Child lock and protection for plastic windows: types, installation

When choosing double-glazed windows, it is customary to pay attention to their heat and sound insulation properties. Undoubtedly, these are the most important characteristics for which they are valued. And modern windows are equipped with handles that can be easily opened by even the smallest children - the consequences of their curiosity can be sad. Therefore, it is equally important to think over a security system for windows, especially if there are children in the house.

The conventional term “children's window locks” combines various devices that prevent the window sashes from fully opening. These are reliable means of protecting children and pets from falling out of windows. In addition, comprehensive equipment of the apartment with such mechanisms will help prevent illegal entry into the home.

There are many types of locks on the market that can be installed when replacing double-glazed windows or on existing windows. The choice should be made based on the design of the window, frame material and the reputation of the manufacturer. Let's look at the most common and popular types of protection.

Handle with built-in lock

This hardware looks like a standard window handle, only with a key cylinder. Suitable for plastic and wooden frames with tilt or turn mechanism. The lock secures the sash in two positions - fully closed and folded. Installed to replace a conventional handle; no additional drilling or other work is required.

Installation

Remove the decorative trim, unscrew the screws and remove the base handle.
Measure the length of the pin.
Select a suitable handle with a lock with the same parameters.
Install it into the existing holes and secure it.

Minuses

The need to open the window with a key every time to ventilate the room. It is not possible to open a window equipped with a handle with a lock slightly.
The key can be lost.
You need to be careful and not leave the key in the lock. Manufacturers specially produce them in red to make them more visible.
After each manipulation of the sash (closing, moving to the folding position), do not forget to lock the lock with the key.

Other types of blockers

The steel mechanical lock is convenient for installation on windows that do not have a tilt-and-turn function. The device is mounted on the inside of the frame and allows you to open the sash over a limited distance.

There are more budget designs - wrappers and lockers with buttons without locking with a key, handles with a comb or hook, opening angle limiters. Such mechanisms will be sufficient to protect pets from accidental falls. Children will quickly understand where to press or how to remove the hook to open the window.

Screw fastening with a key.

Manufacturers produce protective accessories in various colors. You can easily choose an option that suits the overall interior of the room. It is important to understand that even the most expensive, but poorly installed locks and interlocks will not perform their functions. Therefore, if you are not confident in your practical skills, invite a specialist for installation.

Overhead window lock

Attaches to the bottom of the sash and frame. It is the most reliable protection against plowing. The most convenient design for frequently opened tilt and turn sashes. The window can easily be switched to ventilation mode without a key (as opposed to handles with a lock), while full opening is blocked.

Installation

It features simple installation, consisting of the following steps:

install the locking part of the mechanism in the lower end part of the frame;
close the sash;
through special holes, mark the location of the lock mate on the frame;
fix it with self-tapping screws;
install decorative elements;
insert the key and check the installation quality.

Minuses

The disadvantages of such a lock include the need to drill holes in the double-glazed window frame, although this does not in any way affect its thermal insulation properties. A popular company for the manufacture of such locks is Roto, a cheaper analogue is (BSL Baby Safe Lock).

Mortise lock for windows

Child locking of windows is also done in radical ways. One of these is the installation of a mortise locking device. It is mounted inside the profile, showing only a key hole from the outside.

Installation

Installing protection on windows in the form of a mortise lock allows you to achieve complete confidence that it will be impossible to open the unit. The installation of the entire device is carried out exclusively inside the profile, so only the connector for the key protrudes outside.

To carry out independent installation work, you will need a milling machine.

You should work extremely carefully; one careless movement can damage the mechanisms and disable all the fittings.

The installation process goes like this:

process the sash with a power tool to create a niche. Its dimensions must match the parameters of the purchased blocker;
place the parts of the part into the hole;
secure with bolts;
prepare a second niche;
insert a well;
secure with the fasteners included in the kit.

Selecting a lock for a PVC structure is a responsible matter; each device meets certain requirements, but may not meet the requirements of the owner of the house. Therefore, you should consider all the presented models and select the one that will cope with the requirements placed on it and prevent childish pranks.

Advantages and disadvantages

A mortise lock has different qualities.

Advantages:

reliability;
invisibility;
fixation strength.

Flaws:

complexity of installation work;
the need to make a hole in the profile.

Setting priorities

Why is a window dangerous for a child? He can break it and get hurt by the fragments . It can open the door and fall out . But even if nothing like this happens, an open or broken window during the cold season is the most direct path to colds, sore throats and other diseases.

What exactly your child is capable of, you yourself may not know. Even if he has never been overly active and has never thrown toys, breaking a window can happen completely by accident. And a bird flying onto the windowsill will make even the least curious child want to get it.

A minute is enough for the baby to climb onto the window

And it’s not so important what exactly you need: protecting children from windows or protecting windows from children, the main thing is that the presence of a little tomboy in the house forces you to think seriously about it. Which made me study the methods and methods of this protection. There were a lot of them. In addition, most of them are also excellent anti-hacking tools.

So, decide what you need: so that the windows do not open at all, open only for ventilation, or entirely, but with a guarantee that the child will not fall out when leaning out into the street. And choose.

Child lock for moving window sash

The lock is a small latch that secures the sash. It can be installed in several places at once: at the bottom, in the center and at the top of the window. It is suitable for children's rooms that need frequent ventilation.

Installation

The blockers are attached simply: just mark the mounting points and screw the block using self-tapping screws onto the fixed part of the window structure.

Attach the blocker to the stationary part of the sash and make markings with a pencil.
Drill holes with a drill.
Install the blocker and secure it with self-tapping screws.
Close one hole with a decorative plug, and insert a lock with a key into the second.
In the closed position, the sash only works for ventilation.

Lock with locking cable

The system is installed in the middle of the frame and is often equipped with a cable - in the locked position, the sash can only be opened to a distance limited by the length of the cable. To open the window completely, you need to use a key. Suitable for installation on balcony doors, vents and other opening elements.

Installation

Find the area where the block with the locking device will be located (it is better to prefer the lower part; if you attach the mechanism at the top, it will interfere with the functioning of the valves).
Mark the plane.
Make holes with an electric drill.
Place the block and secure it.
Place the part on the opening sash.
Secure the cable.
Check the correct functioning of the system.

When the installation is completed, an adult must put the entire system into operation, try to open the sash, the installation is done correctly, when this is impossible.

pros

Quite a high degree of protection both from opening from inside the room and from penetration from the outside - the cable can withstand a load of up to 500 kg, and it is impossible to break it without auxiliary means.
Installed on any type of frame (plastic, aluminum, wood).
Possibility of fixing the opening of the sash to the desired angle.

Hardware lock or child opening limiter

A metal strip is installed at the top of the window between the frame and the sash. The limiter is not visible at all when the window is closed: it is adjacent to the profile. When locked, the hardware lock does not allow the window to be opened more than 8-9 cm.

Installation

The left strip is attached to the frame, and the right one is attached to the window sash. When the window is closed, the slats form one line: the right bar slides into the groove of the left one. A small lever with the letters FSMB is needed to unlock it - to open the window, turn it.

This stopper is suitable for swing and tilt-and-turn sashes. There's no key here. Installs in 5 minutes using a screwdriver and a ruler. If you have a screwdriver, you can do it even faster. Be careful: you will need to tighten three self-tapping screws while standing on the windowsill near an open window.

Step by step instructions

Let's look at the most popular options.

Installing a handle with a key

This is one of the most popular locks, which is installed on windows in apartments and country houses.
A locking mechanism is built into a special handle , to which a key is supplied. For any actions with the sash, you will need a key surface.

Replacement is carried out not only with professional help, but also independently.

To do this, execute the following instruction:

The plug is turned to reveal hidden bolts for fastening elements.
Take a suitable size screwdriver and remove the bolts, then remove the locking device.
Install a new handle with a locking element.
The plug is installed in its original position.

Important! The handle should be installed in the reverse order of how the individual elements are removed from it. This is especially important when doing independent work, as well as when there is a lack of experience.

Another similar type of device is a handle with a push-button lock. It can only be opened if you press the button. Young children practically cannot cope with this.

Invoice and bsl

Installation is carried out according to the following scheme (including from BSL):

Marks are applied to the frame, which are necessary to connect the main block.
Take a drill, thanks to which you create holes according to the markings.
The main part is secured using the supplied bolts.
Then the additional element is connected.

There are two main elements - the main and additional block. The first is attached directly to the window sash. The second element is mounted on the frame. The main difference is the simple opening of the window structure for ventilation. This completely prevents the sash from opening.

Mortise

Fastening of such a product is carried out directly into the profile. The device is suitable for PVC windows with various design features. After proper installation, only the hole of the mechanism itself is visible on the surface.

Installation requires the following sequence of steps:

The sash is milled, where the main part of the lock will be fixed (a milling machine is used, and the dimensions of the niche must correspond to the dimensions of the locking device).
A part of the lock is fixed in the niche, after which it is fastened with bolts included in the package.
A hole is made in the profile to fix the turnkey well.
The keyhole is installed and securely fastened.

Important. It is important to carry out the work with extreme caution. Protection is provided not only for the frame made of plastic or wood, but also for the locking device itself.

Dummy lock

The cover lock is represented by a separate type of handle, which is removed after closing the window.
As a result, the child does not have the opportunity to open the window wide open or in another plane.

Installing a removable handle involves replacing conventional fittings that do not have a built-in locking element .

The main difference is the presence of a special fastening and a rotating mechanism.

On the sash with a cable

Such locks include three parts. The first is the main one and one end of the cable is connected to it. To remove the opening restriction, the manufacturer is developing a mechanism with a special key. An additional part is provided for fastening the limit cable. The latter is fixed to it during operation of the device.

Installation includes the following sequence of actions:

Select a location for installation and take careful measurements and markings.
The holes for the bolts are made using a drill (it is important not to use a hammer drill, as serious damage is possible).
Using a screwdriver or screwdriver, install the limiter, which is the first part of the device.
Using a similar scheme, an additional block is fixed to the opening window sash.
A cable supplied in the kit is connected to both components of the lock.

Important! Professional installers recommend using the bottom of the window for fixation. This ensures simple opening of the window structure, and the mechanism operates quite accurately.

"Plug" with removable handle

Child protection on plastic windows is done by replacing the standard handle with a removable handle that has a plug in the form of a socket. Such fittings have a special locking device that protects the mechanism from outside influences. An important advantage of such a device is the ability to perform ventilation.

You can buy a similar handle anywhere (in a hardware store or a company that sells PVC structures and is involved in their installation or repair).

Installation

Installation of protection on windows of this type can only be mounted with tilting structures, without a rotating mechanism. After closing the sash, the handle is removed and the hole is closed with a decorative plastic element. Such a system does not give the child a single chance of discovery.

Installation is also absolutely simple: the stationary handle is unscrewed, a new block is mounted, secured with only one bolt.

Advantages and disadvantages

Advantages of a removable handle:

pleasant appearance;
the presence of a plug that masks the mounting holes;
high level of protection.

Disadvantages of the pen:

the constant need to attach and then disconnect the mechanism when opening or closing is required;
there is a possibility of putting the fittings away and then having to search for them for a long time when the need arises.

What it is?

The name “child lock” is a conventional name for a number of stops that are necessary to secure the rotary function of the sash .
The installation ensures daily ventilation of the premises, but does not allow children to fully open the window.

Such solutions exclude the child from going out onto the balcony or cornice. Fastening blockers is allowed on any type of frame, including wooden or plastic models. This also includes modern design options, such as eurobeams.

Note! Installation of special locks with child protection is possible not only on new windows, but also on previously installed structures.

Most of these structures include the following elements :

Guide corner.
A gasket under the main element that protects the external material from mechanical stress.
Housing with locking mechanism.
Key to unlock the locking device.

When choosing a lock, it is necessary to take into account the specifics of a particular window design, the type of opening and the dimensions of the device. Manufacturers produce models from different materials that differ in color. This allows you to select suitable elements for different types of frames. The choice is also made taking into account the interior design.

Popular window lock manufacturers

There are many companies involved in the production of window accessories. Here are the most popular manufacturers of high-quality window fittings:

Austrian company MACO. All of the company’s fittings undergo additional anti-corrosion treatment. The manufacturer's warranty is 10 years or 40 thousand cycles of use. The company mainly produces window handles with a lock or a push-button interlock as security devices. The average cost of one mechanism is 550 rubles (at the time of writing);
German company ROTO. Specializes in the production of various security locks for any windows. The average cost of the mechanism is 300-500 rubles. The company’s specialists can develop an individual design of fittings at the request of the customer. However, such products will have a high cost;
The European company Baby Safe Lock specializes in devices that protect children from various troubles. The BSL window lock differs from similar products from other manufacturers by additional protection in the form of a red key. This aspect allows you to control the presence of a key in the lock and remove it during the process. The company produces a large number of window locks, the average cost of which ranges from 450 to 1000 rubles;
The English company JACKLOC mainly produces window stops or cable locks. The average cost of products from this manufacturer exceeds 1,500 rubles. Window locks with stops are available in a variety of colors. The length of the cable is 200 mm, which allows you to open the window to a maximum of 150 mm. The products fully comply with Russian standards and have a high safety margin.

What other protection is there for windows against children falling out?

Professionals advise using comprehensive child protection for plastic windows, and not limiting yourself to one device, especially since the price is reasonable. If a smart kid opens one lock, the next one will stop him.

Some rely on mosquito netting. The material and fastening are not able to withstand the weight of children; it is better to use it only against insects.

Anti-vandal film coating and grilles can be recommended as additional protective equipment.

Other types of protection

It is recommended not to limit yourself to one type of lock - use a set of protective measures. If a child manages to overcome one obstacle on the way to an open window, the next one will stop him.

Many people still believe that a mosquito net is pretty good protection. This is not true - ordinary material cannot support the weight of a child. Now nets are offered from modern durable fabrics, which can already be considered as one of the elements of protection, but they are quite expensive and must be used in conjunction with mechanical devices. As additional window security measures, we can recommend:

Double-glazed windows with anti-vandal film, which will protect the child from injury if the glass breaks. You can paste the film yourself onto an already installed window. In addition to safety, such glass has another advantage - if damaged, it does not crumble into fragments, maintains relative integrity and can perform its functions for some time.

The film prevents the glass from shattering into fragments
Grilles restricting access to the casement window. They can be equipped with the entire window or only a potentially dangerous area. Installed on the inside or outside of the window. It is important to securely fasten the grille to the supporting structures. This is a necessary and useful option if you like to keep your windows completely wide open in the summer. When choosing it, you need to pay attention to the fact that the distance between the rods is small and the parts do not have sharp ends. There is no need to install bars on all windows; at least one should be left free in case of fire.

These grilles are installed across the width of the window frame using bolts.
So called "security gate" installed in front of the door to the balcony. They are a low metal fence with a gate that can be locked with a key. An effective means of restricting children's access to the balcony. For older children, this is no longer a serious obstacle.

A well-thought-out system of locks, blockers and other means can protect your family from harm. But you should not blindly rely on mechanisms and devices, because even the most reliable of them can fail. Explain to children the rules of safe behavior, do not keep objects near windows that a child could climb onto the windowsill, try not to leave children without constant supervision.

Window grilles

Perhaps the most well-known way to prevent babies from falling out of the window is protective bars on the windows. However, their installation requires significant costs and must be performed by an experienced technician. If the main function of the protective grille is the safety of the child, then it makes no sense to install a continuous sheet; it is enough to cover only the lower part of the window to a height of no more than 100 cm, depending on the height of the baby. In this case, it remains possible to quickly leave the premises in the event of a fire. If the owners pursue the goal of additionally protecting their property and preventing strangers from entering the house, the grille should be solid.

When choosing a protective grille, special attention must be paid to the following factors:

There are no horizontal elements that the child could use as supports and climb out.
Strength and reliability of the entire structure.
Possibility of installing a mosquito net on the window.
The distance between the bars should not exceed 10 cm so that children cannot crawl between them.

Children's bars on windows

The first thing you need to do before you start installing grilles on windows is to carefully measure the dimensions, because if an error is made in the calculation, installation will be impossible. You should also pay attention to appearance, although this is of course more a matter of taste and aesthetics, but you always want to combine business with pleasure.

Children's window bars are less functional than those designed to protect the home, but they are less bulky, do not spoil the external design of the window, and can be easily moved by adults when necessary. The materials of the kidstop grille are durable and metal. Many products are already painted from the factory, but if necessary, you can repaint them in the style you want. This product does not seem bulky, but it is quite durable and can withstand even high loads well.

Protective grilles for kidstop windows have the following advantages:

The frame is made of steel, the rods are vertical, located close to each other. The device provides good protection against falls from heights.
The frame is attached in close proximity to the slope; steel brackets are used for this.
When fastening, only the side slope is involved, so you do not have to worry about the integrity of the plastic window. The grille does not interfere with the use of the mosquito net.
The fence can be removed fairly quickly.

Grill installation method

Knowing how to put a grill on a plastic window , you can either do it yourself or follow the work of the installer. Any work must begin with site preparation. To do this, you need to measure the window, subtract a few centimeters from its size, since the grille should be slightly smaller than the window opening. It wouldn't hurt to provide a lock. When purchasing a structure, pay attention to how often the rods are positioned: the farther they are from each other, the less efficient and rigid the structure is.

Installation begins with marking the wall for pins. The most convenient way to do this is to simply attach the fence to the wall, after which holes 15 cm deep are drilled in the wall, into which pins are driven. The frame is welded onto them. The hinges are mounted in a counter pattern; this will help fix the grille, and it can no longer be removed. After this, the structure is welded to the hinges. Irregularities are smoothed out, the structure is cleaned, degreased and painted.

A baby guard will help protect your baby from falling out of the window. You can calmly go about your business without worrying that the child will climb onto the windowsill and fall out.

Dangerous games with window handles

Imagine the situation: you left the children to play alone in the room, being completely confident that the situation was under control. Really, what could happen? There are no fragile or sharp objects there, no medications, there are plugs on the sockets, special, safe furniture has been chosen.

However, children are extremely unpredictable people. They suddenly decided to play pirates, and one of them had already opened the window and leaned out of it to check what the ship was heading for. Trouble is not far away... Children fall out of windows.

This plot may sound like a Hollywood thriller script, but it is actually much more real than you think. It is enough to type the phrase “a child fell out of a window” into a search engine to understand that such accidents occur alarmingly often in the country. The news is literally full of reports of such tragedies.

Photo: an open window - the path to pediatric traumatology Modern windows are truly high-risk devices, especially if the rules of use are not followed. Opening does not require any effort, and the mosquito net only creates the illusion of safety - it will not catch the child if he falls.

Anti-vandal film on windows as an additional protective agent

The film is an additional safety net if the child accidentally breaks the window. The glass will not shatter into fragments and will not harm the child; in addition, parents receive several bonuses:

theft protection. It is much more difficult to break glass with anti-vandal film; this requires additional effort;
tinting - the matte surface of the film has a reflective effect and prevents the penetration of sunlight into the room on a hot day.

You can stick the protective film yourself on the inside of the sash, and if handled carefully, it will last for many years.
