types of hinges for plastic doors and their adjustment

Plastic doors are practical, inexpensive and therefore very popular products. They are used as balcony partitions, as well as entrance and interior structures. They can be of different sizes and purposes, but they will not be able to work without fittings. Therefore, hinges for plastic doors must be selected carefully and adjusted in a timely manner. It is these elements that bear the main load. Next, let's look at the differences between hinges for plastic doors and how to choose them correctly.

The procedure for adjusting the hinges of plastic doors

Plastic doors have long conquered the market and are in great demand as entrance and interior structures. The material is quite practical and reliable in operation, but just like other doors, plastic ones can sag over time, rub against the frame, etc. But in order to fix the problem, it is not at all necessary to call a specialist, because the main thing is to find the source of the malfunction. And the main reason for door sagging is in the hinges, so it’s worth understanding how to properly adjust the hinges of plastic doors.

Pros of hidden awnings

Hidden hinges for doors are now in quite high demand and the reason for this is a number of undeniable advantages of these mechanisms.

• Hidden canopies are anti-vandal fittings; these mechanisms are not visible, which means they cannot be affected in any way, for example, by cutting them off;
• The range of hidden awnings is impressive in its diversity; there are awnings in furniture design, for light cabinets, and at the same time, powerful metal hinges for doors and a quarter are produced;
• Door canopies for hidden installation are especially valued in furniture production; such fittings do not spoil the appearance of the products;
• The amplitude or opening angle of a hidden canopy is often greater than that of its traditional counterpart;
• Hidden hinges are made of either stainless steel or high-strength alloys and can withstand quite heavy loads.

Hidden hinges are made of high-strength alloys, especially for canopies for steel doors

Balcony door adjustment options

This process is quite simple and does not require specialist intervention or special skills. The main rule is to follow the instructions for setting up the mechanism.

Door sagging

The main signs of fabric subsidence:

In these cases, it is necessary to begin adjustment. Due to this malfunction, a small gap forms between the hinge and the sash, so horizontal adjustment of the leaf will be required. The sash must be pulled either to the right or to the left. To adjust the bottom hinge, you need to find the screw that is located at the bottom of the frame. After that, take the hexagon, insert it into the screw and turn it counterclockwise (to move the hinge away from the door leaf) and clockwise (to bring it closer).

After adjusting the lower unit, move on to the upper one. To do this, you need to open the door to see the top hinge. Its design is slightly different from the bottom one, but it also has a hole for a hexagon. Here, too, it turns in the required direction until the lower loop stops clinging to the threshold.

Height adjustment

How to adjust the hinges on plastic balcony doors if abrasions and dents are noticeable on the seals? To correct the problem, you need to tighten the lower hinge assembly. First you need to find the screws, which are most often covered with a special decorative cover. To remove it, the pad first pulls towards itself, and only then upwards.

After removing it, you can get free access to the screw, which is tightened to the left to vertically lift the blade down and to the right to lift it up.

Setting the pressure

It is recommended to carry it out several times a year: in winter in order to seal and retain heat in the room, and in summer to loosen it to improve air circulation. In addition, the clamping mechanism may become weaker due to deformation of the web or due to wear of the seals. As a result, a gap is formed and the structure loses its heat-insulating and sound-proofing properties.

To eliminate the malfunction, it is necessary to replace the seal with a new one, or adjust the clamping mechanism. To do this, at the end of the mechanism there is a cylindrical element - an eccentric. There can be up to 7 pieces on one canvas.

Adjustment of the clamping mechanism takes place in several stages:

Setting up loops

Many people have a question: how to adjust the hinges on plastic balcony doors? And this can be done either vertically or horizontally. The vertical adjustment was discussed a little higher, but as for the horizontal adjustment, we still need to figure it out.

To do this, open the door and remove all the screws from the hinges using a hex key. After this, you can remove the decorative trims, under which the adjustment screws are hidden. The screws on each hinge must be turned the same number of times.

The need for the procedure

Plastic doors and windows are airtight and prevent dust, moisture, and cold from entering the room. As a result, they become practical for living spaces, but require periodic adjustment of the mechanisms.

Adjustments are made as needed

When manufactured at the factory, windows and doors are adjusted in height, taking into account the pressure against the frame and the inclination. After installation, the product does not require special operation, but over time the mechanism wears out, the fastenings become loose and the need for adjustment arises. This process may be required in the following cases:

• disruption of easy movement of the sash, jamming of the mechanism when opening/closing;
• loose pressing of the sash to the frame, penetration of cold air;
• loosening of the handle mechanism;
• change from cold to warm season;
• sagging window or door sash.

There are situations when even professional adjustment does not allow returning the functionality of a plastic product and serious repairs are required. This is necessary if the quality of the fittings that were used to install the product is poor. Incorrect assembly during installation also causes breakdowns. Such defects cannot be eliminated on your own and require the help of a specialist.

Adjusting the plastic entrance door

A plastic door is installed not only on balconies, but also in offices and as an entrance structure. This option is more practical if, for example, compared with a wooden door. It can withstand sudden changes in temperature, is resistant to high humidity and does not dry out over time. The only thing is that it needs to be periodically adjusted using loops.

The need for adjustment

The first thing you should pay attention to is the feeling of drafts in the house when the door is closed. This indicates that there is a gap in the door that needs to be repaired. You can determine the displacement of the canvas in a simple way: draw a pencil around the perimeter, after which it will become noticeable that the lines do not run parallel to each other. Another way to check the tightness of the door is to place a small piece of paper between the frame and frame and close the door. If the leaf is pulled out when the door is closed, then it is necessary to adjust the pressure; if the leaf does not come out, everything is in order with the density.

Sometimes it becomes necessary to adjust the handle itself if it begins to wobble or falls out of its socket. If at least one malfunction is detected, it is worth starting the adjustment, but if the warranty period of the installed door has not expired, then you should not take any action yourself, otherwise the company may refuse its warranty obligations.

Three-hinged door adjustment

The entrance type of door, for example, unlike the interior door, has a slightly different adjustment mechanism. On such a canvas there are basically three loops - the top, bottom and a loop, which can be either in the middle or located next to the top. This is the most optimal arrangement needed to support the weight of the sash. Adjustment of a plastic door with three hinges is carried out depending on the design of the hinge itself and the clamping mechanism.

It can be adjusted in three planes. To move the leaf horizontally or vertically, you need to turn two screws in the desired direction, and the door pressure is adjusted using a screw and a bar, which is located between the hinge and the frame.

In order to adjust the misalignment, you need to remove the decorative trim on the hinge, then open the door and remove the screw that secures the strip. Now you can remove the bar, under which 6 mounting screws and an adjustment screw will immediately become visible. With its help, you can adjust the vertical displacement of the door by 5 mm in one direction or another.

To raise or lower the door, you need to find the adjusting screw, which is located below, at the end of the hinge. It is also covered with a decorative strip, which is very easy to remove. Using a screw, the door can be either raised by 4 mm or lowered by 1 mm.

At the upper end of the hinge there is an adjusting clamping screw, which is used to adjust the door clamping mechanism.

How to adjust plastic entrance doors horizontally and vertically on WX type hinges? To adjust the blade horizontally, you need to use the side screw. It is located under the decorative trim, but first the screw that secures the hinge itself is unscrewed, then the screw that locks the decorative body of the hinge is unscrewed, and only after that you can get to the adjusting screw. By turning the screw, you can shift the position of the blade either to the left or to the right.

In order to loosen or strengthen the pressure of the door leaf, you need to use the hinge located on the door frame. First, the decorative cap is removed and an eccentric with slots will be visible under it. To be able to rotate it in the required direction, first unscrew the locking screw, after which the required eccentric angle is set and locked in the required position. In this way you can loosen or strengthen the pressure.

Adjusting the clamping mechanism

In other words - frontal setting. It is worth adjusting the pressure twice a year: in winter - tighten it, and in summer - loosen it. To do this, from the end of the canvas you need to find the locking pin, which has a special notch that helps determine the position of the clamping mechanism. If the notch is turned towards the frame, the pressure is weakened; if it is turned away from the frame, it is strengthened.

Sealant

If a plastic entrance door has been used for a long time in a skewed state, then there is a possibility that the seal has worn out or become deformed. In this case, it must be replaced with a new one with a similar cross-section.

The old deformed seal is removed, and the groove itself is cleaned of possible dust, glue and dirt, after which it is coated with glue and a new seal is installed.

The same principles apply to the adjustment of interior plastic door structures. As you can see, there is nothing complicated and you can cope with the work yourself without anyone’s help. It is necessary to regularly monitor the operation of both the plastic entrance door and the interior door, and then the structure will last for decades and keep the house cozy and warm.

What should I do if the handle does not turn all the way?

1. Check how the strikers are installed and rearrange them if necessary - see how to do this above.
2. It is easy to determine the installation of fittings with an offset:

• Open the sash, the handle should be in a strictly horizontal position.
• Look at how the trunnions are located - the protruding elements on the lock. They should be exactly in the center of the slot.

Photo: we check the position of the trunnions using thin lines (marks). Different hardware manufacturers may have two or one risk. © oknamedia If the trunnions (one or more) are not centered, you will have to disassemble the fittings a little. We do not recommend doing this yourself, because during the dismantling process you can damage the fittings - it is better to call a specialist.

And if you know how to use a screwdriver and want to take a chance, let’s start making adjustments.

The entire mechanism on the sash consists of several parts. You need to find the element on which the pin is displaced.

• We find the joining points of this element and unscrew all the screws that hold the part to the sash.
• We hook the part by the edge and pull it out of the profile.
• Using your fingers, return the pin to its place - exactly in the center between the risks or align one at a time (depending on the brand of fittings).
• We insert the part into place and tighten the screws

Photo: aligning the trunnions is not as difficult as it seems, but skill and a screwdriver are required. © oknamedia

Sometimes it happens that the handle itself fails. It is easiest to diagnose its breakdown, because the handle is the most visible part. How to replace the handle on a balcony door, read the article How to replace a window handle?

Adjustment when blowing through the balcony door

There are several reasons why a balcony door may leak:

• The door is installed with a violation of the geometry of the frame and/or sash, the pressure of the sash is uneven - as we have already explained, it will not be possible to eliminate this defect on your own.
• Thin reinforcement is installed in the sash or it is cut into pieces when installing the lock. In this case, the sash bends, will not fit tightly to the frame in the upper and lower corners, and will leak. This defect can only be eliminated by replacing at least the sash.
• The seal has dried out and does not perform its function.

Photo: inspect the seal: if it is cracked, looks dry and does not regain its shape after pressing, it is time to replace it. © oknamedia

• The sash is sagging and there is no proper pressure - this defect and the method for eliminating it have already been described
• The mounting plates on the fittings were not selected for this profile - this may be a manufacturing error. The mounting strips depend on the size of the profile system and vary in thickness.

Photo: if the striker is thinner than necessary, the sash will not be pressed tightly and airflow is guaranteed. If it is thicker, the sash will close very tightly*. © Roto The defect can be corrected by installing the correct strikers; this can only be done by a specialist.

If it is blowing strongly and you have to wait a long time for the technician, you can slightly increase the pressure by adjusting the trunnions. You will need a 4mm hex wrench or pliers

Photo: you need to open the sash and turn the trunnion towards the room. The trunnions have an eccentric and when turning they either move away or, on the contrary, approach the counter strips. As a result, the clamping force can be adjusted to a value of ± 0.8 mm (using the example of a Roto fitting trunnion)*. © Roto This is a simple option as a temporary measure, but it is better to install the correct strikers and return the trunnions to the neutral position.

Hinges for metal-plastic doors: a generalized view

Plastic doors have become widespread in Russia and have received well-deserved love from consumers due to their exceptional properties and interesting design features. They are not structurally complex, but require some attention.

Cons of hidden awnings

In the material world, absolutely ideal things, in principle, do not exist; hidden models of canopies also have disadvantages.

• Installing hidden canopies is much more difficult than installing conventional hinges;
• Canopies with decent quality hinges and supporting parts cost from 1,800 rubles. a piece. Of course, there are loops on the market for 500 - 700 rubles, but they are not regulated and are often of dubious quality;
• Not all canopy models can be disassembled, so in order to remove a door leaf based on cheap hinges, these hinges must be completely unscrewed;
• To embed such a canopy, the door leaf must have the appropriate thickness. Hidden hinges for metal doors usually have somewhere to go, but problems can arise with framed interior doors.

Not every interior door is thick enough to install hidden hinges

Design Features

The hinges are subject to significant loads, which necessitates their manufacture from metal and stainless steel. Some parts may be made of Teflon. All these materials are strong enough to provide the mechanism with a long service life.

The purpose of installing hinges is to secure the canvas to the frame so that it can be opened. Hinges should not only serve as an element necessary for opening the door, but also ensure smooth and easy opening, as well as a tight fit of the door leaf to the frame.

The correct choice of hinges, timely and qualified adjustment will ensure excellent operation of the mechanism throughout its operational period.

The hinge for plastic doors consists of:

People who understand the design of hinges for ordinary wooden interior doors will notice that they have a similar design. However, a feature of the hinges under consideration is that they require adjustment of both their position and the position of the fabric attached to them.

The adjustment makes it possible to move the leaf in any direction relative to the doorway by a few millimeters. With proper adjustment, you can achieve a tight, gap-free fit of the door to the frame, as well as trouble-free operation of the locks.

The hinge for a plastic door is in most cases installed through a special tab, which is also called a template. The template is fixed on the door in the place where the hinge will be installed in the future. It is the template that allows you to adjust the door horizontally.

Vertical adjustment is carried out thanks to special adjustment screws hidden in the hinge itself. The screws are closed under special caps that protect the mechanism from dust and are also installed for decorative purposes.

Long service life of doors is achieved through the use of durable materials. The design of the hinges uses Teflon - a very durable and lightweight material that ensures the durability of the mechanism. In addition, special ball-type bearings are built into the hinges, ensuring easy opening of the blade and reducing wear on the mechanism.

Don’t forget that the design allows you to take care of it at any time, carry out lubrication procedures, and adjustments. It is thanks to the design features of the mechanism and the possibility of maintenance that good reliability and durability of the product is achieved.

There are also situations when the hinge for a plastic door cannot withstand the load and requires replacement. Basically, such problems can arise due to defects in the production of structural elements of the mechanism; as a rule, the product body (most often aluminum) or the axial cylinder fails.

This is not a common occurrence and when using high-quality fittings, breakdowns practically do not occur. If a breakdown does occur, the loop can be replaced with a new one that is suitable in size. Structurally, the procedure for replacing the hinge is quite simple and does not cause problems even for beginners.

The canvas touches the edge of the box or is not covered tightly

This problem can be encountered in the autumn-winter period if the fittings were moved away from the corner as much as possible. The frame deforms slightly and engages with the axles.

To fix the problem, you need to move the sash horizontally

It is important to do this evenly and avoid distortion. The mechanism is adjusted in two places: on the upper and lower loop

Before you adjust the plastic balcony door yourself, you need to open it completely. This will provide convenient access to the mechanisms.

Sequentially rotate the screws of the upper and lower hinges. We control the moment when the pins stop clinging to the door frame.

After this, the adjustment can be stopped. But it is better to achieve a position in which both edges of the sash are equidistant from the inner edge of the installation box. This can be easily checked by tracing the outline of the closed canvas with a pencil.

The first thing to do is to identify the location of the loose fit:

This allows you to determine the clamping density. When adjusted correctly, the leaf should be pulled equally tight at all points.

If it passes freely, you will need to adjust the gap by turning the trunnions. On one side they have a mark: a slot or a stamped dot. In the factory state it is directed upwards.

To make the clamp tighter (winter mode), turn the trunnion with a hexagon or a screwdriver with a mark toward the room. If you need to loosen the door, turn the mechanism in the opposite direction - with the mark facing the street.

Modern fittings allow you to additionally change the clamp using the lower loop. If you look at the opening with the door panel closed, you will see a screw on the front. By rotating it, you can achieve the necessary pressure in the loop area.

Sometimes it is not possible to achieve the desired effect using this method.

This means that the cause of the malfunction lies in the deformation of the structure itself or a violation of the installation technology. The defect can be temporarily eliminated by twisting the strike plate a couple of millimeters towards the street. But it is better to call qualified specialists for repairs.

The handle is attached to the blade with two screws. Over time they become loose. To tighten the fastening, turn the plastic plug that closes it 90 degrees and use a screwdriver to tighten the screws until they stop.

If the handle closes tightly, not completely, or the fittings move with a squeak, the cause of the malfunction is improper engagement of the pin with the strike plate. In spring and summer, the frame may be slightly deformed due to warming. Therefore, the problem is solved by turning the axle to the “summer” position - with the mark towards the street.

Sometimes a defect appears after adjusting the balcony door. In this case, we look at how the mechanism engages when closing:

If the above methods do not help, then the problem lies in the tape mechanism of the fittings. It is better to entrust repairs to a qualified installer.

For clarity, we suggest that you familiarize yourself with the technical aspects by watching the video.

How to choose?

When choosing hinges, you need to pay attention to such details as the material from which the part is made, the overall quality of the part, and the manufacturer of the part.

If you choose hinges from a branded manufacturer, you can be sure that such fittings will serve you for many years. As a rule, both the upper and lower hinges are designed for an average of 200 thousand openings and the same number of closings.

If you have chosen a budget option for hinges for metal-plastic doors, then you’ll be lucky, but in most cases they are also enough for a long period of use.

For entrance doors that are subject to frequent opening and closing, reinforced aluminum alloy hinges should be selected. Durable material significantly increases the reliability of fastening.

For balcony doors, it is necessary to select hinges, the assembly feature of which suggests the possibility of adjustment. This feature will allow for vertical or horizontal adjustment of the structure.

Hinges on balcony doors: requirements for them, main types

First of all, canopies installed on double-glazed windows and balconies must be strong and durable. When checking these qualities, the product must withstand at least 20 thousand cycles of closing and opening the valves. And therefore, in balcony-window double-glazed windows, window awnings are most often installed, which have a special design and can withstand regular loads and a large number of closing and opening cycles.

The manufacturer usually equips door structures for balconies with awnings with a profile installed in the overlay (photo).

But if the product is installed in an office or other public place where the load cycle will be greater, it is better to abandon the balcony type of metal-plastic door and choose a regular door with regular door hinges.

If you have made your choice in favor of ordinary doors that will be installed in the opening between the balcony and the living room, then you will need to use special canopies for installing the structure.

Preparing to remove the door and hinges

Removing the fabric from the hinges is not very difficult and can be done even by a non-professional. To remove the door, you need to prepare tools, without which completion of the procedure is impossible.

It would be a good idea to read the instructions for a specific product, since the procedure for removing each specific door may differ slightly due to the peculiarities of the mechanism. As a rule, any instructions outline the procedure for removing the door.

Once the tools are purchased or found in the household, the plastic door hinge can be removed. Removal must be done sequentially, according to the points below.

Conductor setup

The conductor provides the following adjustments:

— adjustment of the height of the overlap

- adjustable sash width

— horizontal adjustment of the carriage (similar to the hinge carriage)

— adjustment of the offset of the fastening in the frame in relation to the edge of the sash (carried out using pads in the jig)

Using the adjustments described above, we adjust the jig based on the preset of the hinge, the width of the sash, the height of the overlap, as well as the desired location for attaching the hinge to the frame.

If preinstalling the loop and setting up the template causes difficulties, the technical support department will prepare instructions (installation diagram) specifically for the client’s profile system. To do this, the client provides the technical department. support samples of profiles (frame, sash) with reinforcement and seal, or drawings of these elements in dwg format.

When to adjust doors

Any, even the most expensive and beautiful plastic door, sooner or later needs adjustment. The need for periodic adjustment is caused by the following reasons:

• The building itself may sink. In this case, the box warps slightly.
• Problems may be caused by incorrect installation. Here the errors will appear within a month. As a rule, the door closes tightly or poorly.
• Incorrect or intensive use. Often this requires adjusting the hinges and replacing the seal.
• Doors can sag under their own weight. Here the hinges are also tightened in height, plus sometimes the pressure of the plastic door needs to be adjusted.

Before adjusting a plastic door, you need to diagnose it. This will give a clear understanding of which node needs to be configured.

First of all, inspect the door leaf and the receiving frame around the perimeter. Minor abrasions indicate that the door has sagged. Immediately mark these places with a pencil.

Scuffs at the end of the door leaf indicate subsidence.

If you notice that it has begun to leak through the doors, it means that there is a gap somewhere along the perimeter of the canvas. It is useless to examine the clamp with a lit candle in plastic doors; the flame will begin to fluctuate only if there is a very large gap, while small cracks are covered with a seal, and the candle does not react to them.

The sagging area can be identified using a sheet of paper. You need to insert a sheet of paper between the frame and the door leaf, then close the doors and try to pull the paper out. If the pressure is good, the paper will sit tightly, but if the pressure is poor, you will pull out the sheet freely. This way the entire perimeter is examined.

Diagnostics of pressing of plastic doors with a sheet of paper.

To identify the curvature of the door leaf horizontally and vertically, you need to completely close the doors and trace the leaf along the contour with a simple pencil. Next, take a ruler and measure the distance from the drawn line to the edge of the box.

Vertically you need to measure at three or four points, horizontally at two or three points. Although sometimes without measurements, the naked eye can see where the doors have moved.

We trace the door leaf along the contour.

Not so often, but it still happens that the cause of problems with doors is the locks themselves, the strike and locking strips of the locks, as well as the latches and the door closer. Therefore, when diagnosing, we recommend disconnecting the closer first, and then checking the lock group. If everything is in order there, then you can begin checking according to the scheme described above, that is, searching for abrasions, checking the pressure with a paper sheet and outlining the outline of the canvas.

By the way, if you find out that the reason is in the closer, then information on setting it up can be found “here”.

The main components of a standard plastic door.

Removing the door and hinges

So, the sequence of actions is as follows:

The door is moved to the closed position, and the protective caps covering the hinge mechanism are removed. The protruding part of the cylinder is recessed from above using a hammer and a punch, and then, at the bottom of the loop, using pliers, the cylinder is grabbed and pulled down until it comes out of the groove.

The door tilts forward (toward itself) and pulls upward with force. It is necessary to lift the door five centimeters to release the lower support pin. The fact is that the lower part is not secured in any way, so to remove the door you just need to pull the door up and move it a little to the side. The hinges are unscrewed from the door and frame using a hexagon or screwdriver.

The process is completed, the hinge for the plastic door is removed. After purchasing a new hinge, the assembly procedure is performed in reverse order.

We make the adjustment ourselves

Whatever the cause of the problem, you may need the following tools to fix it:

• hex keys of different sizes;
• screwdrivers - flat and Phillips;
• roulette;
• pliers;
• plastic gaskets.

Set of hex keys for adjustment

When sagging

If, when opening, the balcony door touches the frame with the lower edge of the sash, the sagging should be eliminated by adjusting it. To do this, the door leaf is “moved” up and shifted to its upper hinge.

1. Open the sash in the swivel position (note, this is not the ventilation position).
2. Using a 4 mm hex adjustment wrench, turn the screw near the top hinge at the end of the sash. Make a few turns to the right (clockwise) to tighten the sash. After that, close the door.
3. Remove the decorative plastic caps from the bottom hinge. This will give you access to the top adjustment screw on the top end of the hinge.
4. Turn it clockwise. The door will rise.
5. Check the freedom of movement of the sash. If necessary, repeat the operation.

Adjustment on the top loop when sagging

When touched in the middle part

In this case, the sash needs to be moved closer to the hinges.

1. Move the sash towards the bottom hinge. Insert the adjusting key into the side adjusting screw and pull the sash in the direction of the hinge.
2. If this is not enough, repeat the process for the top loop. We described its adjustment above.

Bottom Hinge Adjustment

Usually this procedure is enough for the sash to stop clinging to the frame.

Pressure adjustment

The pressing force of the door leaf to the frame is adjusted using locking elements. They are located on the sash itself. Most fittings are equipped with locking elements in the form of eccentrics. Rotate them using pliers or an adjusting wrench until the pressure is optimal.

To achieve greater efficiency, before the adjustment process, read the corresponding diagrams in the instructions or on the hardware manufacturer’s website.

It is usually recommended to adjust the pressure twice a year: in the winter, set a tighter pressure, in the summer - looser.

Handle adjustment

This is the simplest task that you can easily complete in a short time. A common problem with handles is that they become loose over time.

1. Rotate the plastic cap at the base of the pen 90 degrees.
2. Tighten the exposed screws with a screwdriver. Do this carefully so as not to damage the pen body.
3. If the play does not disappear after tightening the screws, this may indicate a crack in the handle body. In this case, the handle needs to be replaced.

Adjusting the hinges

Hinges on plastic doors need to be adjusted from time to time. You can understand that the time for adjustment has come based on various signs:

Depending on what defect was identified in the operation of the door mechanism, horizontal, vertical adjustment, or adjustment of the door pressure (for drafts) may be necessary. You should not delay adjustment for a long time, since improper operation of the door will loosen the entire system, and if used incorrectly, a complete replacement of the mechanism may be required, which will incur additional costs.

Horizontal adjustment

This type of adjustment is necessary when the door is sagging. The door sag under its own weight and at the slightest distortion it becomes necessary to interfere with its operation.

The process can be divided into the following steps:

Vertical adjustment

This type of adjustment is made when it is necessary to raise or lower the door. To make adjustments, you need to find an adjusting screw. The screw is located directly on the hinge, at the bottom end. It may be closed with a special plug that needs to be removed.

Adjustment is made using a 5 mm hexagon. By rotating the hex clockwise, the blade rises, and counterclockwise, it lowers.

Pressure adjustment

The pressure of the door is essential; if the door does not fit tightly enough, a draft occurs. Adjustment is very simple and is done using a hexagon.

You need to find the pin that locks the door. There is a special notch on it, which determines the tightness of pressing the door to the frame. To increase the pressure, the trunnion is rotated “away from the frame”; to weaken it, vice versa.

So, a plastic door hinge can be easily removed, installed, or adjusted if necessary. If you were unable to resolve the problem yourself, you can always call a qualified specialist who, for a small sum, will adjust the hinges, replace them, or perform other actions necessary to bring the mechanism into proper condition.

Adjustment instructions

Once you have discovered that the door needs adjustment, try not to put this off for too long, otherwise it may require expensive repairs (see Repairing plastic doors with your own hands).
A dented seal, a displaced sash, or tight turning of the handle are clear signals that it’s time to take action. Below are instructions on how to adjust plastic doors.

Horizontal adjustment

Most often, it is necessary to eliminate sagging that occurs due to the door’s own weight:

• Open the door to gain access to the screws that secure the trim trim. Unscrew the screws from the two top hinges with a three-millimeter hexagon.
• Close the door and remove the trim, which contains several adjustment screws. You want the longest one, positioned horizontally.

Vertical adjustment

Sometimes you need to raise or lower the entire door evenly. To understand how to adjust a plastic door vertically with your own hands, you need to find an adjusting screw at the bottom end of the hinge, directed along the axis of the hinge.

A 5mm hex wrench is needed for adjustment. Rotating it clockwise will raise the door, counterclockwise will lower it.

Pressure adjustment

The pressure adjustment of plastic doors should be changed regularly when the season changes - loosen for the summer and strengthened for the winter. This is done very simply, using the same tool - a hexagon.

• Locate the locking pin on the door frame.

As you can see, there is nothing complicated in such a matter as adjusting plastic doors - the video on our website will help you understand this in more detail.

If you have more serious problems than those described here, call a specialist to your home - he will fix everything quickly and efficiently. You must call a specialist during the entire period of warranty service.

Tips for use

To make the hinges last longer, they need to be lubricated. To do this, you can use WD-40 or other similar greasy lubricants. Machine or refined oil and hot wax work very well. This procedure should be carried out periodically, which will increase the reliability of the part. Lubrication of hinges involves the following steps:

How to replace the hinges of a plastic door, watch the video.

Loop adjustment

Note

Horizontal adjustment of the hinge must be done with the cover removed (the same principle in the hinges KTV, KTN (Dr Hahn), DHN, DHV (Astex)), because :

— in this model there are hinges, the side plug can only be removed from the removed cover

- quite often, in order to make horizontal adjustment, it is necessary to “loose” the fastening screws

To remove the cover you need to use a slotted screwdriver.

Installation of hidden door hinges

For smooth and easy opening of doors, the hinges must be correctly selected and installed. Secret or hidden hinges are popular. To install them, special holes are made in the door frame and leaf, and when the door is closed, such canopies are not visible.

According to regulations, door hinges, including hidden ones, must provide the following characteristics:

• free opening and closing of the door leaf;
• reliable fixation of the door and frame during operation;
• safety, they should not allow spontaneous separation of the leaf from the door frame;
• possibility of fixing the blade in extreme positions;
• high-quality performance of functions during the warranty period.

Hidden hinges from well-known manufacturers are highly durable and can withstand up to 200,000 operating cycles.

To create hidden hinges installed on interior doors, an alloy of four metals called tsamak is usually used. It contains magnesium, aluminum, zinc and copper. Tsamak has good fluidity at a low melting point, so high-temperature furnaces are not required to organize production. It has sufficient strength and a smooth surface.

To give finished hinges an attractive appearance, a nickel, chrome or brass coating is used, which can be glossy or matte.

Hidden door hinges do not spoil the appearance of the door leaf, since they are not visible in its closed position

If we talk about the design of hidden hinges, it will be more complicated than that of overhead or mortise models.

The invisibility loop includes the following elements:

• metal case;
• hinge, it hides in the hinge body;
• lever, this element consists of two parts, which are fastened together by a steel movable axis, and ensures the connection of the hinge and the blade;
• anti-friction bushings, they serve to improve sliding.

The hidden hinge consists of the following main elements: a central rotary (1) and two fixed axes (3), a lever (2)

Before purchasing hidden hinges, you need to decide on the direction in which the door will open. There are left-handed and right-handed products, as well as universal ones. The latter can be installed on any side of the box.

In addition, there is a division of hidden hinges into unregulated and adjustable. It is clear that the cost of the latter will be higher. If we talk about the materials of the door frame and sash in which such hinges are installed, then these are wood, aluminum or steel.

To ensure maximum service life, experts recommend installing three hidden hinges, especially for heavy door leaves.

Depending on the load the hidden hinges are designed for, their sizes will differ. For interior doors, it is enough to install parts that can withstand a load of 40–50 kg. The weight of entrance doors can reach up to 200 kg, so more powerful models will be needed here.

Although universal hinges are more convenient to install, they are less reliable. Experts recommend choosing hidden hinges taking into account the opening of the canvas.

Left and right door hinges are more reliable, but universal models can also be purchased

Hidden hinges with closer

These models appeared relatively recently. Since the hinge and the closer are combined in one mechanism, there is no need to additionally install a shock-absorbing device. Externally, such products are practically no different from traditional ones. They may be larger in size, but the main difference is in the design.

A hinge with a closer has a built-in shock-absorbing mechanism, the main working element of which is a spring. When the door leaf is opened, it stretches, and when released, it begins to shrink. Thanks to this, the sash returns to its original closed position.

In order for the door to close smoothly, an oil shock absorber is used. In this case, the spring is placed in a cylinder. It has a system of valves through which oil moves from one chamber to another. When opening a door, the process occurs in one direction, and when closing it, in the opposite direction. The spring is in a viscous medium, so the compression rate decreases. This allows the door leaf to close more slowly and softly and avoid hitting the frame.

The closer spring, placed in a cylinder with oil, ensures smooth closing of the door

When choosing hidden hinges with a closer, you must take into account that they cannot be installed on all types of doors. Such models cannot be used for heavy products, since the hinges will not be able to perform their functions normally and will quickly fail.

The number of hinges will depend on the weight of the door leaf:

• for a sash weighing 40–50 kg, experts recommend installing two hidden hinges with a closer;
• for doors weighing from 50 to 90 kg, it is necessary to install three canopies;
• For fabrics weighing more than 100–120 kg, it is not recommended to use such loops; it is better to install a powerful closer separately.

Another disadvantage is that the door block must be positioned with a slight deviation from the vertical. This is necessary to facilitate the operation of the parts mechanism. In each case, the angle is determined individually. If you make the slope large, then the door will close on its own even without a closer. At a small angle of the blade, the operation of the mechanism becomes more complicated, and it fails faster.

Due to the presence of a built-in shock-absorbing mechanism, such hinges have a number of advantages:

• no impacts of the canvas on the box, which prolongs the service life, and if there are children in the house, then the presence of a door closer will minimize the risk of injury;
• there is no need to hold the door when closing;
• no drafts.

How to adjust a plastic door

Over time, plastic doors begin to let in cold air. The doors do not fit tightly, the closing and opening mechanism does not work well. We will tell you how to adjust a plastic door yourself.

Plastic doors need to be serviced regularly: lubricate fittings, change seals, adjust sashes. We recommend checking the condition of the doors once a year. It is easier to identify and correct deficiencies at the initial stage in order to prevent expensive capital repairs.

How to adjust plastic doors: identifying damage

After several years of operation, plastic balcony and entrance doors let cold air through, do not fit tightly, and jam when closing and opening. Self-adjustment eliminates malfunctions. Before starting repairs, determine the nature of the defect.

The canvas clings to the box and creaks. The door opens and closes with interference, friction is noticeable. Adjusting plastic doors eliminates the defect: if it is not corrected in time, the profile will be damaged.

The doors sagged. Failure is detected during inspection of the structure. If a gap forms in the upper part of the door, and the lower part touches the threshold, this means that the canvas is sagging.

The handle wobbles or jams. In the first case, the cause of the defect is inaccurate operation, in the second - wear of the lock core, clogging or sagging of the door leaf.

The 3-way mechanism jams. The reason may be contamination of the part or its wear.

Adjusting plastic doors yourself: instructions

Before you start adjusting the entrance or balcony plastic doors, check the integrity of the seal. Often its defects become the cause of drafts and leaks. If the seal is damaged, replace it with a new one. In this case, there is no need to disassemble and adjust the mechanisms.

Before starting repair work, close the doorway and outline the frame around the perimeter. The contour should be parallel to the inner edges of the door frame. If there are curvatures, you need to eliminate the sagging of the sash and adjust the canvas in height.

First remove the decorative trims from the hinges, this will provide access to the screws.

Door pressure adjustment

Loosely fitting doors lead to drafts in the house and the formation of condensation on the glass. Before you start adjusting the door pressure, you need to determine the place where the gap appears.

If there are areas where the sashes do not fit tightly, you need to correct the defect by turning the axles. These are bushings at the end of the door frame, located along its perimeter. When the door opens and closes, they move.

On one side of the pins there is a mark or a stamped point - this is a mark. It should be directed upwards. To make the clamp tighter, turn the axle with the hexagon mesh towards the room. So the door is switched to “winter” mode. To loosen the fit, turn the mechanism towards the street.

The pressure of the sashes is also adjusted using the lower hinges. Open the door and look at the door leaf: you will see a screw at the bottom. Rotate it to obtain the required pressure on the door leaves.

If both methods of adjusting plastic doors did not help, the problem lies in deformation of the structure or incorrect installation. To eliminate the defect, move the strike plate 1–2 mm closer to the street and secure it.

Adjusting the plastic door height

Sagging of the sashes more often occurs with double-chamber double-glazed windows - they have more weight and more load. To lift the sash, you need to rotate the screw on the bottom hinge. To do this, take a 4 mm hexagon and turn it clockwise - the canvas will rise, counterclockwise - it will fall. This method helps if the canvas has sunk evenly around the entire perimeter.

The skew of the door leaf is indicated by the sagging of one side relative to the bottom edge of the opening. To level the defect, adjust the upper and lower side loops. Turn the screw with a hexagon. If you turn to the right, the canvas moves in the direction of the key, if you turn to the left, in the opposite direction.

Displacement of the blade leads to an increase in the load on the glass. If the defect is not corrected, the glass unit will burst.

If moving the adjusting screws does not help, the sagging is corrected with pads under the glass unit. To install them, the glazing beads are dismantled and calibrated wedges are installed. Leave repair work to the masters: you must strictly follow the technology so that the door does not become deformed.

Adjusting plastic door hinges

The hinges of the door panels are adjusted if their lower part catches the frame or does not fit tightly. The problem arises in the autumn-winter period, if the fittings are relegated to a corner. To eliminate the defect, the sash is moved horizontally: the position of the top and bottom hinges is adjusted.

Attention! To adjust the plastic profile, tighten the upper and lower hinges. If you adjust only one, then the position will change only at this point. The entire profile may become deformed.

The sequence of actions is as follows.

Open the door and trace the outline of the canvas with a simple pencil. If both edges are equidistant from the inside of the installation box, you can complete the adjustment of the plastic door.

The back adjusting screw may be located in the corner or above the door leaf.

Adjusting plastic door fittings: handle repair

The handle is attached to the door with two screws. Over time, the structure becomes loose, the fastening needs to be tightened. To do this, turn the plastic plug hiding the screws 90°. Screw the screws until they stop.

Two screws are hidden under the plastic plug.

If you cannot turn the plastic plug, pull the door handle towards you and try again. Loose screws may rest against the plug and interfere with rotation.

If the handle turns worse after repair, remove the plastic plug again and loosen the screws a little. Try opening and closing the door again.

If the handle closes poorly, does not turn completely or creaks, you need to correct the coupling of the pin with the strike plate. The principle of operation is the same as in the case of the clamp: turn the axle with the mark towards the street, that is, move it to the “summer” position.

Breakage of the handle may be the result of incorrect adjustment of the balcony door. In this case, the sequence of actions is as follows.

If the above adjustment methods did not help, this means that the problem lies in the wear of the belt mechanism.

Adjusting the fittings of a plastic door includes working with hinges. If during operation they become loose and begin to wobble, you need to tighten them with a hex wrench. If the lower fastening is torn out, you need to change the hinge. There are two reasons for the breakdown.

If the handle makes sharp sounds when opening and closing the front door, remove the handle and lubricate the mechanism. If lubrication of the moving parts does not help, you need to change the locking system.

To lubricate handles and other moving parts, use machine oil. Source https://legkovmeste.ru/
