Child locks on windows. Installation from 20 minutes on the day of application

No. 1. Types of window locks

Window locks are fairly simple and inexpensive designs that can be installed on all types of windows , whether plastic or wooden. They allow you to make the window safe for the baby, bring peace of mind to parents, and at the same time increase the burglary resistance of the window - thieves from outside will not be able to open the lock. Often, locking structures are also installed by pet .

Based on the operating principle and installation location, locks are divided into several types:

• handles with a lock or button;
• rim locks;
• mortise locks;
• blockers;
• cable locks.

There is also a socket lock or plug , which does not have a locking mechanism, but the function of the design is the same - to prevent the child from opening the window on his own. Also, some people classify a “comb”-type window restrictor , but its usefulness is questionable - almost any child will be able to fold back such a restrictor and open the sash.

The choice of pen is yours

Which option is best? As you know, there is no friend for taste and color. If you need to leave the house for a long time, but want the premises to be ventilated, it is better to give preference to the first and third options. If reliability comes first, the second and fifth options will help out best.

Well, when it is important to combine maximum efficiency with aesthetic appeal, there is nothing better than the fourth and seventh options. Fortunately, almost all of the listed methods for protecting windows can be easily implemented on your own. You just need to buy the necessary parts and read the installation manuals, which are found in large quantities on the World Wide Web.

No. 2. Handle with lock

Some parents use the most budget-friendly and at the same time the most inconvenient way to protect windows - they simply unscrew the handle. No handle means no way to open the window. Cheap and cheerful. After a couple of weeks of using this method, all its disadvantages and inconveniences, which you can already guess, will come out. It’s better to spend a little money, but get a design that’s really easy to use.

A handle with a lock is one of the most popular and effective ways to secure a window structure. The regular handle is replaced with a special one with a built-in lock, and it can only be activated with a key. The sash can be fixed in an open, closed or tilted position - the functionality of the window does not disappear anywhere; the sash can be opened and closed only after the key is inserted into the lock. The only negative is that you will have to carry the keys with you and use them even when you need to open the window for ventilation.

Some manufacturers make the keys quite bright, since at first, according to collected statistics, many parents forget the keys in the window handle.

A type of handle with a lock is a handle with a button . The operating principle is the same: to turn the handle, you need to press a button. It is pressed quite hard, so a child, even the strongest, will not be able to do it. Plus for adults - no need to look for keys and carry them with you.

Installing a new handle to replace the old one is not difficult - almost anyone can do it. You will need to turn the plug, unscrew the bolts hidden under it, remove the old handle, insert a new one, tighten the bolts and close it all with the plug. The new handle is inserted in the same position in which the old one was removed. Nothing complicated. With minimal experience, this is a matter of 10 minutes.

Window locks in open position

There are times when it is necessary to ventilate a room with the door in the open position, for example, in offices, apartments or country houses where children have grown up. Or fix the open door to bring furniture into the house. An open and unfixed sash, due to a draft, can hit the window slopes, knocking off flower pots and everything that previously stood or lay on the windowsill.

Types of sash locks in the open state:

• Sash rotation lock
• Sash lock – stopper

Let's look at them in more detail:

• Sash rotation lock

• Allows you to firmly fix the open window in a comfortable position up to 90°. You can ventilate the room with the desired intensity. Also convenient when cleaning windows;
• Simple control: open the sash to the desired angle and lower the handle down - the sash will lock;

For example, the manufacturer of window fittings Roto has such a blocker called locking scissors Roto 486820*.

Flaws:

• Installed in production;
• A user who is inexperienced or unfamiliar with this lock can “break it” by trying to slam the door - repairs can only be made by a specialist.

No. 3. Rim lock

A child lock on windows built into the handle complicates the ventilation process, and if this is critical for you, then it is better to install a padlock. Its main advantage is that even without a key, the door can be folded back , letting fresh air into the apartment.

A rim lock consists of two elements: the main part with the locking mechanism is attached to the bottom of the sash, the second block with a tongue is mounted on the frame. The key is only needed to open the window completely.

Installing such a structure should not cause any problems for those who know how to use a drill. First, the places where the lock elements will be fixed are marked on the sash and frame, and then holes are made for them, after which they are fastened with bolts. All necessary elements and parts are usually supplied with the lock.

More information about the operating principle of children's window locks can be found on the website https://oknafdo.ru/accessories/kids_lock/.

Opening limiter

Opening limiters include several types of devices, among which the most popular are the “comb” and the rotation lock. “Comb” is considered the simplest child lock that does not require the use of keys. The product allows you to open the sash only to a certain level, which is regulated by special grooves on the comb. The mechanism is located at the top of the window, so a small child cannot reach it. However, older children will have no difficulty climbing onto the windowsill and easily throwing back the comb.

The rotation lock is mounted in the upper part of the window system and allows you to open the window for ventilation, locking it in the desired position. As a rule, such window blockers are installed on budget plastic structures that do not have a window mode. With their help, you can open the door by 30 degrees or less, which allows you to let fresh air into the room, but minimize the risk of an unwanted fall.

No. 4. Mortise lock

As the name of the design suggests, a mortise lock differs from a rim lock only in that its elements are hidden in the sash and frame . It is impossible to guess its presence, the aesthetics of the window are not spoiled, and the functionality completely coincides with the functionality of a rim lock, i.e. You can open the door without a key. True, for this it will be necessary to install the structure at the bottom of the window.

Installation of mortise window locks is somewhat more complicated than all others. The performer will need training and the availability of professional tools. Milling is done in the sash for one part of the lock. For this, a special milling machine is used, which must very accurately and accurately cut out a niche of the same dimensions as the locking mechanism. The frame is perforated with the subsequent installation of a keyhole. In order not to spoil the appearance of the window and ensure the required functionality of the lock, it is better to seek help from a professional.

Varieties

All child locks for plastic windows have a similar device, which looks like this:

• Guide angle with a gasket that protects the PVC surface from mechanical damage;

Design diagram of the guide angle

• The shutter mechanism is in a housing with a gasket that protects the PVC surface from mechanical damage;

• Key that allows you to change the shutter mechanism mode.

Now let's move on to getting to know the different types of locks:

Group of “fuses” No. 1: handle locks

A window handle with a lock is practically no different from a regular handle

A very simple device that, in general, practically does not change the appearance of the double-glazed window. The principle of its operation: an additional mechanism is installed in the handle, which, when closed, blocks its movement. That is, you can:

• Set the window for ventilation;
• Lock the handle in the desired position by turning the key;
• Pick it up;
• Have complete confidence that the baby will not be able to change the position of the sash in any way.

The installation instructions in this case are not complicated. For example, for me it consisted of the following actions:

1. I chose which tool to use to adjust the locks during their installation. For me it was a medium-sized Phillips screwdriver, but you can use the bolts that come with the product as a guide;
2. I moved aside the plugs that hide the heads of the screws that secure the old handle;
3. I unscrewed the fastening elements , slightly loosened the closing device in its seat, and then carefully removed it;

Unscrewing the old handle

1. I inserted the purchased product into the vacated groove and secured it with bolts;

Installing a child lock in the form of a handle using a screwdriver

Be sure to insert the new lock handle in the same position in which you removed the old handle. Otherwise, you may break the opening and closing mechanism of the window itself.

1. Returned the plugs to their original position.

Can be used

Do-it-yourself repairs are carried out in essentially the same way, since they usually simply involve replacing a broken locking device with a new one.

And an example of such a lock for a PVC window, which can be found in a specialized store:

Sample lock handle

Pros:

• Almost complete absence of changes in the appearance of the window;
• Possibility of blocking different positions of the window sash;
• Low price.

The downside is that a breakdown of the locking mechanism can have a negative impact on the handle itself. That is, until you replace it, you will not be able to open or close the window at all.

Group of “fuses” No. 2: overhead

Overhead child locks on windows are independent devices

The overhead copy consists of a body with a locking mechanism, which is fixed on the window sash, and a counter part mounted on the frame. It is no longer connected to the handle at all, so if it suddenly breaks, you can continue to use the window as usual. But, however, you will have to come to terms with the appearance of an additional visual element on the double-glazed window.

Also, a distinctive feature of this sample is that with it you can tilt the sash for ventilation, but you cannot open the window wide.

I installed it like this:

1. I made markings on the sash and frame for installing both components of the lock;
2. Drilled holes in the marked places;
3. I screwed on the housing with the locking device, and then its counterpart.

The result of the performed manipulations

As an example, I will give the German-made Roto model:

Sample Roto model

Group of “fuses” No. 3: mortise

Mortise window lock with key

Here I want to note two main distinctive features:

1. Difficulty in installation . Inserting a product into a window profile is not so easy, especially without relevant experience;
2. Stealth . After finishing the work, only a small keyhole remains outside, which practically does not affect the appearance of the entire window.

Work performed during the installation process:

1. Using a milling machine, we cut out a seat on the window sash that corresponds to the dimensions of the locking mechanism;
2. partially insert the product into the resulting cavity and secure it with bolts ;
3. Now we process the window profile , creating a hole there for the second part of the device;
4. We install and fix it together with the well.

As a result, the castle is almost invisible to an outside observer

An example of a mortise device that can be seen on store shelves:

Samples of mortise locks with different keyhole colors

Group of “fuses” No. 4: blind locks

Tricky plug

This option does not have a locking mechanism, which provides two significant advantages:

1. Low cost . The simpler the product, the cheaper it is;
2. No breakdowns . No mechanics - nothing to break.

The principle is very simple: the old handle is replaced with one that can be pulled out. That is, you closed the window and took the device with which you can open it again.

The child simply has nothing to open the window with

Installation is similar to the process I described when installing the handle-lock.

Fuse group No. 5: locks with cables

This is what a device with a limiting cable looks like

Three components can be observed here:

• The main element on which one edge of the cable can be fixed with a key;
• Mate holding the second end of the limiter;
• The cable itself.

Here I performed the installation work as follows:

1. I applied markings on both parts of the window for the installation of all functional elements;

Advice: I recommend choosing the bottom part of the window for installation, so that the cable does not interfere with the sash being exposed for ventilation in the future.

1. I drilled with a drill ;
2. Using a screwdriver, I first secured
3. Attached the cable.

Finished work

Here are the characteristics of the English Jacklock model:

Example of the Jacklock model

And the less expensive Ukrainian model “BSL Cable Prime”:

Sample model "BSL Cable Prime"

Group of “fuses” No. 6: latches with keys

Example of a window blocker

In this case, the main feature is fairly effective protection against intrusion by thieves . The device is a main part with a locking mechanism, on which there is a retractable fragment capable of firmly blocking the window sash.

The installation looks like this:

1. In any convenient place, that is, at least on top of the window, at least on the side, at least at the bottom, markings are applied;
2. Holes for fastening elements are drilled;
3. The device is fixed with screws;
4. The screws are closed with decorative plugs so as not to disturb the aesthetics of the double-glazed window.

Blocker in action

I suggest taking a closer look at the example of the Ukrainian model “BSL SASH PRIME”:

No. 5. Lock-lock

Usually lock-locks (or locks) are called ordinary mortise, overhead or handle-mounted locks or buttons. Some manufacturers mean completely different designs by blockers. This is not even a lock, but rather a latch, and it is recommended to install several of them at once on the sides and top of the window. The structure is attached to the sash, and when the “tongue” is lowered, it does not interfere with opening and tilting the window. If you turn the moving elements of the latch, the window can be closed tightly. The child will not be able to open all the elements - they are fixed very tightly and high. There are also locks where locking occurs using a button or key.

In terms of convenience and functionality, such locks are inferior to other children's window locks, but they are very cheap and easy to install. Another nuance is the appearance of a window with blockers: not everyone may like the visibility of these elements.

Design and main functions of a window lock

Locks for plastic windows come in various types, but they all have practically the same operating principle. A special device is locked with a key, thereby preventing opening.

The window lock consists of the following elements:

• a guide angle and a corresponding gasket that protects the window plastic from damage;
• housings with a locking mechanism;
• linings under the body to protect window plastic;
• key that unlocks the mechanism.

Window lock device

The window lock is used for:

• protecting children from falling out of the window opening. Almost all children are curious. They like to play with window handles and other mechanisms. A small child will not be able to open the window without a key, and, therefore, will not be able to fall out of it;

Without a window lock, children's games are unsafe

• protection against window break-ins and entry into the apartment. Most thieves cannot open strong metal doors, so they try to enter the apartment through window openings.

Burglar protection is the second important function of locking devices

It is always better to prevent a tragedy than to suffer its consequences.

No. 6. Plug or socket lock

The name of the socket lock is not very safe. The design was named this way because they saw similarities with the functioning of any electrical device. It is enough to insert a special removable handle into the positioned hole for the window to “work.” This hole in the frame is aesthetically covered with a special plug. The child will have no chance of opening the window, since the handle will be hidden from the parents. The sash can be fixed in any position. The main disadvantage is that the pen must be carried with you or hidden in the most unpredictable place so that the baby does not find it. This solution will cost minimal waste, but is suitable mainly for plastic windows.

Installation is easy to do yourself. Instead of the old handle and plug, a new decorative plug is mounted, and on one bolt, so that it can be turned and a removable arm can be inserted.

Rules for installing the grille

In order to correctly install the kidstop grille, you must:

1. Pay attention to the location of the bars, that is, only vertically, so that the baby does not have the opportunity to climb onto the bars, as if on steps.
2. The structure must be rigid, and the rods must be made of high-quality and inflexible metal.
3. Installation and fastening of the structure is carried out externally, on the side slopes of the main wall, and only by experienced specialists.
4. The width between the bars should be such that a child’s leg or hand does not get stuck.
5. In accordance with fire safety requirements and in order to prevent accidents, the grille should not be lower than one meter.

No. 7. Cable lock

The cable lock closely resembles typical bicycle locks. One part of the structure with a locking mechanism is attached to the sash, the second - to the frame, with a cable located between them. The length of the cable is chosen so that it is possible to open the window for ventilation, but at the same time it would be impossible to open it. It is better to choose removable locks that, if you have a key, allow you to get rid of the cable and completely open the window.

Cable locks are the most popular installation option for sliding window structures . It simply does not allow the sash to be opened wider than intended.

Types of sliding window grilles

Sliding grilles can be divided into types; their differences depend on the features of operation and operation.

Moving the grille along the length of the window in one direction

This type of sliding grille is a complex structure. If it is folded, then it is located on the side of the window opening or overlaps the window structure. When folded, the grille can be hidden between the main wall and the combined wall.

Moving the grill along the length of the window in both directions

This type of lattice is called an “accordion”. It is one structure of two halves, and also has the ability to move apart like an accordion, that is, to simultaneously move in both directions along the length of the window opening.

There are cases when accordion-type gratings are used in combination. One part of the structure is fixed fixedly, and the other can be moved apart like an accordion along the length of the window.

If the length of the window is large, you can use a sliding window grille, the middle part of which is fixed permanently, and the movable elements of the “accordion” structure can easily be moved to both sides of the window opening.

Sliding bars on windows

Moving the grid using the principle of scissors movement

This type of design involves a sliding mechanism that works on the principle of scissors: sliding metal gratings are fastened together by movable elements and move along rollers that are located at the bottom of the structure or at the top, on a suspension.

No. 9. Manufacturers of child locks for windows

When it comes to the safety of children and the apartment, it is better not to save, since the small amount saved will not compensate for the sad consequences of installing low-quality locking hardware. Many companies produce locks for windows, but it is better to give preference to the largest and most reputable ones:

• MACO is a large Austrian company that produces pens with locks and buttons. All metal elements undergo anti-corrosion treatment, so the manufacturer provides a long warranty on the mechanism;
• Baby Safe Lock mainly produces overhead locks, which are simply installed and allow the window to open in ventilation mode. The block can be white or brown, and the key has a red holder - you won’t be able to forget it in the lock. The lock can be installed on any type of profile;
• ROTO is a German company that develops window locks of various designs, but most of all in the range of special handles with locks. It is possible to manufacture custom-made lock elements;
• JACKLOC produces cable locks and handle locks, all of which have a high safety margin;
• PENKID – Turkish locks for sliding windows have an excellent price/quality ratio.

How to limit window opening?

When installing new windows in your home, you need to pay attention not only to the appearance of the product, but also carefully study the technical characteristics of the future window.

Many companies take into account all customer comments and produce structures to special order, taking into account all the nuances of the room. Recently, it has become very important to install a child lock immediately at the company. It is very comfortable. The lock will fit perfectly under the window. It doesn't need to be customized.

A logical question would be: “Since the window opens, does that mean a child or pet can easily get through the gap and get out?” Fortunately, falling out is not possible. The gap is very small and it is impossible to crawl through it.

In conclusion

The desire to save money leads craftsmen to invent homemade window locks. Usually these are metal chains. Sometimes mosquito nets and combs are used for protection purposes: these elements have completely different tasks, so they will not be able to ensure the safety of the baby to the required extent. Special locks with a well-thought-out design are not so expensive as to risk the life and health of the baby.
