Comb for plastic windows - features and installation of limiters. How to choose a door opening limiter Window limiter for PVC windows how to install

Changing outdated ones wooden windows on modern metal-plastic ones, customers often try to save money. Minimizing costs primarily concerns fittings, and many clients of window installation companies believe that the window opening limiter is something they can do without. In fact, this small device costs mere pennies, and the benefits from it are not at all as little as it might seem at first glance.

We refurbish our windows

From the name of this item alone, it is clear that it should fix the sash either in a given standard position (open/closed/microventilation), or expand this rather narrow list of window possibilities. Some companies offer their clients to purchase an opening limiter for plastic windows even before installing them, which is the most reasonable option, because then the lock is perfectly adjusted to the profile. However, subsequent installation is quite possible; moreover, you can use not only the standard limiter model offered by the profile manufacturer, but choose another, more suitable option.

There are several types of window opening limiters, each of them has its own advantages and disadvantages. You can learn about each type, as well as the pros and cons of specific models, from this article.

Briefly about the main thing

So, the limiters presented on the domestic market come in five main types:

1. There are several modifications of combs - there are external and internal ones, they are made of PVC, they are easy to install, in addition, this option is the most budget-friendly.
2. An internal window opening limiter that prevents the sash from swinging open and fixes it in a given position. Made of metal, has a simple but reliable design, durable.
3. Window opening limiter with a cable - looks quite aesthetically pleasing, is a structure made of a metal core, 5-10 mm in diameter, in a polymer braid, which is easy to wipe clean from dirt. Strong, safe, has high level indicator for opening and closing, because it is practically not subject to mechanical stress.
4. A lock-limiter for opening plastic windows, the main function of which is the ability to close the sash using a key.
5. Limiter for swing opening, with the ability to set the window to “vent” mode.

Different models of these clamps may differ significantly in appearance, however, their operating principle is similar. Important nuance, which must be reported to the master when placing an order, is the type of window itself, or more precisely, what type of mechanism the sash has (hinged or tilt-hinged).

Comb limiter - best seller

By far the most popular model of device that fixes metal-plastic windows, is a comb. There are several models of this type of device. More often than others, it is customary to use an external window opening limiter. The comb is then located on the visible part of the sash. It looks simple - it is a plate with grooves, which is attached to the immovable part of the profile, and the second part of the device is screwed to the sash - a hook adjusted to size, to which the bar clings. Due to the fact that it has 3-4 connectors, this allows you to fix the window in several positions. The comb is also a good option for installing an opening limiter for wooden windows because it does not require insertion into the mechanism of the window system.

There are also more complex mechanisms - these are internal limiters, which are also made of plastic (white or brown, less often - other colors). There the comb is part sliding mechanism, which is installed between the sash and the profile.

Under lock and key

Some modifications of stoppers are systems with locks that are locked using special keys. Among them is a window opening limiter, which is located directly in the handle. IN closed position it disables the ability to open the window wide, but the function of ventilation and micro-slits remains.

This model involves, first of all, ensuring security, because it is an additional means of protecting the premises from intruders. Also this good way Protect children and pets from the danger of falling out of the window.

Complex designs

The most labor-intensive to install and operate from a technological point of view are internal limiters. Models from this series provide braking of the sash and prevent it from opening wider than an angle of 90º. This device is very small; it is equipped with three grooves that help adjust the opening angle of the window.

The advantage of using this fixation method is that it is invisible, but it is better to install it at the time of assembling the window itself, so that it is more convenient for the master to adjust all the moving parts of the structure (hinges, handles, swinging systems).

Safety comes first

Most common cause To install a limiter is to ensure the safety of children. Curious by nature, they often like to spend time near windows, watching what is happening outside the house. Unfortunately, there have been cases when children fell out of windows, leaning on mosquito net, are happening more and more often.

By installing such a lock on the window, parents will be able to prevent a tragedy without depriving their children of the pleasure of looking out the window and without closing it tightly. Ventilation of the room is also often complicated, because it is not always necessary to open the window wide open. Depending on the time of year, it is necessary to adjust the width of the gap sufficient to ventilate the room. Opening limiters will help you find best option and ensure comfort in the home.

The last but not least reason for installing a limiter is to protect slopes and walls from damage resulting from excessive opening of the window. This can be done by the owner of the premises through negligence, or it can be the result of a draft. In any case, it is better to initially install a limiter, the cost of which does not exceed several hundred rubles, than to deal with repairs later.

Master or hand-made?

The window opening limiter can be installed independently if the lock model is external. Then you need to attach the stopper parts to the sash profile and frame. Before securing the elements, you need to outline the places where they will be placed. The clamps are secured with self-tapping screws using a screwdriver or screwdriver.

It is better to entrust the installation of devices with more complex modifications to specialists. Even minimal intervention in the window system can lead to disruption of the mechanism, and then the window will not fit tightly to the frame due to displacement of the elements. As a result, the window will lose its soundproofing and energy-saving abilities.

Specialization: master of internal and exterior decoration(plaster, putty, tiles, drywall, lining, laminate and so on). In addition, plumbing, heating, electrical, conventional cladding and balcony extensions. That is, renovations in an apartment or house were done on a turnkey basis with all necessary types works

Let me start with the fact that a window opening limiter can imply not only different mechanisms, but also different functions - it all depends on what you are going to limit and why.

For example, you can block the function of fully opening the sash from children so that the child does not accidentally fall out of the window. Or you can install shut-off valves that provide micro-ventilation mode.

Let's look at this in more detail and learn about the types of child locks and devices for air exchange from the street.

Window restrictors

Note. The very word “limiter” as a mechanism implies a forced reduction of any area of ​​​​action. And each of them has its own instructions for installation and use.

Children's locks

I. Handle-lock

Perhaps the most popular stops for plastic windows are metal handles with built-in shut-off valves that can be opened with a key. The advantage of such a lock is that in appearance and general configuration it is no different from a standard handle.

Therefore, to install it, it is enough to simply swap the mechanisms. After replacement, you will be able to lock the transom in two modes - closed or folding, from which you can only exit with a key.

II. Rim lock

Such a limiter is quite easy to install with your own hands: it is screwed onto the lower sash on the swing side. Pay attention to the top photo - you can clearly see that the working part of the lock is beveled, which makes it possible to open the transom in a folding mode without using a key.

But here you should be very careful when installing so as not to protrude beyond the rebate and not to support the rubber seal, as this will prevent a tight fit and the transom will not close.

III. Wrap-limiter

The principle of operation of a restrictive lock is very similar to that of a rim lock, but it is not fixed to the sash, but underneath it to the lower profile of the frame - you can see this in the photo above.

The essence of the operation of the device here is quite simple - you turn the screw flag and lock the mechanism with a key. The restriction here is effective only for the swing mode - folding opening can also be performed in the closed position of the device.

IV. Mortise lock

In the top image you see what a mortise installation of restrictive shut-off valves for plastic windows looks like. According to the principle of operation, the design is very similar to the overhead version and the twist.

However, installation here is much more difficult - you will need a tool to mill the bottom profile. Therefore for self-installation such a mechanism is not always acceptable. Here, too, only the swing mode is locked - the tilting function is not limited.

V. Handle instead of a key

Now let's figure out how to install a handle with a plug, which functions exactly the same as standard option, but is removed after switching to the desired mode. For installation:

• the original handle is removed;
• in its place is screwed a socket with a decorative cover, which moves up and down, opening and closing the adjustment hole.

Essentially, this is the same key, only slightly larger.

VI. Stopper with chain

A children's restraint with a cable is similar in design to a door chain, only most often it acts as a restrictor metal cable in isolation, but there is also a circuit.

This locking option does not provide for fixing the sash in any specific mode - they all function. Only with a swing opening can the transom move away only within the length of the cable that is locked with a key. For a child, such protection is quite enough.

VII. Locking sliding windows

Blockers for sliding systems. For example, it is much more convenient to make a plastic or aluminum window on a loggia sliding rather than hinged - this saves usable space.

Of course, here you can adapt the kind of blocker that we discussed in the first paragraph, but it is still much more convenient to fix it on the side, as shown in the top photo. Several holes are drilled in the frame, and you can fix this lock in any mode that is convenient for you and safe for the child.

For most blockers, self-tapping screws are used when installing them. When choosing screws, I advise you to limit yourself to a diameter of 3-3.5 mm and a length of up to 15 mm, so that it does not rest against the steel profile inside the PVC.

3 modes of micro-ventilation

1. Microclimate handle:

The handle of the right sash is in micro-ventilation mode, the left one is in the “closed” position

• some manufacturers of plastic windows provide a small opening function in tilt mode even during the manufacture of windows;
• in fact, you buy a product and you don’t need to do anything to make a minimum air exchange - everything is done when arranging the shut-off valves;
• for such designs there are four handle positions:

1. if the lever is turned vertically down, this means that the window is completely closed;
2. a horizontal position of 90° indicates the possibility of swing opening;
3. tilted position up 45°, this is micro ventilation;
4. vertical upward rotation allows you to open the sash in tilt mode.

1. Comb blocker:

• A blocker of this type allows you to limit the opening of the sash in several modes, that is, by the number of notches on the latch. IN in this case there are four of them, but there may be more;
• this lock consists of two parts - a comb strip, which is screwed to the frame at a distance of one millimeter from the sash, and a counter part, which is placed under the handle;
• Since installing a limiter on plastic windows (meaning a comb) is very simple, even a teenager can do it. To do this, one screwdriver and two self-tapping screws are enough.

1. Climate valve:

• The climate valve is not a lock in the mechanical sense of the term, however, it is a limiter that regulates the flow of air from the street;
• since the installer attaches it inside the profile, then from the outside (from the street side and from the room side) only decorative overlays, which do not spoil at all appearance window frame(they are selected by color);
• It is noteworthy that the noise level during operation of such a valve almost does not increase, in any case, you will not feel it, since there is no direct hole here, and the sounds are damped by the walls of the valve;
• The humidity level is controlled by polyamide sensors due to their own coefficient expansion, that is, the dampers do not require power supply.

Conclusion

In order to figure out how to correctly install this or that limiter, you need to carefully read the instructions, which are usually supplied by the manufacturer.

In addition, the installation of some models is described on the site and the video in this article also contains useful information. And if you have your own suggestions, tell us about it on the forum or on this page in the comments.

Previously, to fix the door, various objects or crumpled paper were placed under it. However, progress moves rapidly, and today no one uses sheets of paper to hold the door. And along with such door fittings as handles, latches and hinges, as an alternative to the well-known door chain, special door opening limiters are widely used, which allow the door to open slightly at a given distance.

The need to limit door opening

Limiting door opening using special latches can be useful in different cases, most often - when it is necessary to rationally plan the space in the room and ensure the safety of opening the door. In a similar way can be protected not only door leaf, but also furniture and walls from damage caused by excessively swinging the door open, as well as prevent injuries that can be caused by a sharply slammed door from a draft.

Sometimes it becomes necessary to fix the door in a certain position, for example, if you need to bring a large object into the room or ensure unhindered movement large groups visitors. This is often necessary when the house has Small child, who may accidentally pinch his fingers or hit the doors. It is also somewhat burglar-proof.

The use of special clamps where they are installed at the entrance is becoming especially relevant. double doors, which in open position not easy to hold at the same time. Let's say in suburban buildings It is often customary to install two input structures- steel and glass. The first door can be fully open during the day, held by a latch in a given position, and the glass sheet is used at this time as the main protection and additional source of lighting.

Types of door opening limiters

Door limiters are on the market door hardware V wide range. Each manufacturer strives to make them in intricate designs, polished, chrome-plated, silver or gold, as can be seen in the photo of the door opener. When choosing a door latch, it is advisable to select it in harmony with the fittings already present on the door.

Floor limiters

Exist different types stoppers that are installed on the floor. Some of them are capable of holding the door leaf in a given position, others simply do not allow it to swing open enough to damage the standing pieces of furniture behind the wall or the wall decoration. Among them there are mobile and stationary products.

Stationary floor models include:

1. Magnetic holder. The principle of its operation is quite simple: in the lower part a small metal plate, and the stopper itself with a magnet is attached to the floor in the place beyond which the door should not swing open. When the door is opened, such a plate is magnetized to the stopper and fixed in this position.
2. Door stop. This is the simplest product that does not fix the door itself, but at the same time does not allow it to open more than necessary.

Mobile floor clamps are much more diverse:

• The most common door stopper in the open position is a regular wedge that has a non-slip base and can be made in the form of a figurine toy.
• Another type of floor stopper is a device that fits onto the bottom end of the door, and its legs, which are non-slip, rest against the floor on both sides.

To close or open the door, just press the floor stop of the interior door with your foot, thereby releasing it from the groove. There are other configurations of similar devices on sale, but they all work on a similar principle.

Wall stops

According to their purpose, wall clamps are divided into door slamming and door swinging limiters. Door swing limiters are small parts various forms and styles that are attached to the wall with screws and do not allow the door to hit it. Such devices are simple and magnetic. Their installation is justified when you do not want to spoil expensive parquet flooring with floor limiters, or if you have a “warm floor” system installed under your floor covering.

The open door stoppers that are attached to the top trim are considered more functional. The design in the tilted position does not prevent the door from closing, but if you turn it down 90 degrees, it will create an obstacle to the door closing completely. However, we want to reassure you: you should not be afraid that wall or floor opening limiters will damage the finish of the door. They are made from soft materials or staffed rubber pad in places of contact with the door leaf.

Door stops

If you only want to protect your pets and children from a slamming door, you can put a C-shaped stop on its side or top end, which is made of elastic plastic, rubber or other soft material.

If you need door leaf hold under the right angle, then you should pay attention to the door opening angle limiter, which consists of a metal body that is screwed to the door, as well as a brake pad. In order for the brake pad to extend and the door to lock against opening, you just need to press the foot pedal. To remove the fixation, simply lift the brake pad by pressing the lever.

Locking device limiters

When it is necessary to restrict access to a specific room, locking devices are usually installed. Locks are rarely installed on interior doors. If it is possible to restrict access to the room, for example, to the bathroom, then it is customary to choose door handles with stopper. Such handles are equipped with a latch that holds the door in the closed position using a tongue that fits into the hole of a special strike plate on the frame. Magnetic latches are no less popular.

For entrance doors, locks are installed so that it is not possible to open the door with a key from the outside. Entrance doors often tend to slam shut at the most inopportune moment, for example, when you decide to take out the trash. Magnetic opening limiter front door This will not allow this to happen, since it holds the lock tongue inside the mechanism. For an interior door, a similar function is performed by closing limiters - attachments on the door or stand-pegs under the bottom of the door.

Door stop material

There are a huge number of door locks on store shelves. The price of door opening limiters often depends on the material from which the device is made. Steel, aluminum, steel alloys, brass, plastic and wood can be used to produce door stops. The stronger the raw material from which the latch mechanism is made, the more it can withstand a greater load.

If the latches are intended for a massive and heavy door to the living room or bedroom, it is worth buying stable mechanisms made of metal. If you want to make your bathroom door functional, just choose plastic limiter, which conditionally makes it clear to guests or household members that the room is occupied. If you want to protect your children from accidental finger bruises, then you need to buy plastic or rubber door stops.

If you plan to prevent your front door from swinging open, you should choose metal clamps. In addition, they must have strong magnetization, which can stop the movement of the massive door leaf. For the lungs interior doors Magnetic latches with a lower magnetization force are intended.

If you have to protect furniture sets and finishing from the strong swinging of the door, it is better to choose wall clamps that stop the door from the wall at a certain distance. To prevent damage to the door finish, you should choose stops made of soft materials, for example, rubber, or clamps with soft pads.

It turns out that the door opening limiter is very useful thing. It will protect your furniture, wall decoration, and the door leaf itself from damage when the door is suddenly closed. In addition, your children will be protected from accidental injuries.

To prevent the door from slamming or opening/closing spontaneously, so that it can be fixed at any angle, there is a door opening limiter. There are many types of limiters. They differ from each other structurally, in location, in design. You can choose an element that will match the rest of the door fittings.

Varieties

1. The simplest floor door stop is a wedge with a non-slip base. Designed to limit the door so that it does not open wider than necessary.

2. Another floor stopper is placed on the door at the bottom. It is equipped with non-slip feet that rest on the floor. When opened, the door is released from the groove and set in motion.

3. Magnetic door stop. It consists of a clamp with a magnet located on the floor and a counter plate on the canvas. When opened, the parts connect and hold the door in a certain position.

4. Wall-mounted door stop (swing stop) - an element that is installed on screws in the place on the wall where the door should stop swinging. When opened, the door rests against it and does not hit the wall. This door opening limiter can be conventional or magnetic.

5. A clamp that is attached to the platband at the top of the box. When turning down at a right angle, an obstacle is installed to prevent the door from slamming. To avoid damaging the canvas, wall stops are equipped with rubber gaskets or made of soft materials.

6. A C-shaped plastic clamp is placed on the end of the leaf and thereby prevents the door from slamming.

7. Opening angle limiter. Metal device, which is installed on the door. The brake pad is equipped with a pedal. The pedal is pressed to fix the blade. To set it in motion, the block is raised using a lever.

8. Latch limiters. Inside apartments they are most often used in bathrooms and kitchens. Usually this is a tongue, which, when fixed, fits into the corresponding groove of the strike plate. There are also magnetic varieties.

9. Entrance door latches. When installed, the door cannot be opened from the outside with a key. Magnetic latches prevent the door from slamming shut when you enter the stairwell.

The choice of door opening limiter is determined intended purpose, ease of use, design and features of the room (for example, if the apartment has warm floors or expensive flooring, prefer wall clamps).

Window sash opening limiter (aka “comb”, aka “crocodile”) is a window ventilator. It consists of two parts - a comb (a small bar with indentations) and a retainer. The clamp is attached to the movable window sash, and the comb itself is fixed to the frame. Please note that the window comb merely secures, but does not lock, the window.

Combs are used for controlled ventilation of rooms on rotary PVC or wooden windows. They provide the ability to fix the sash in 2 planes: vertical and horizontal.

Plastic comb (installation under the handle)

Available options:

Plastic comb with 4 positions. Length - 10 cm.

Plastic comb with 5 positions. Length - 12.5 cm.

The window opening limiter is supplied with a painted fastener installed under the handle of the plastic window.

Materials from which the comb for plastic windows is made:
- metal part under the handle made of painted galvanized metal,
- body - made of high-strength ABS plastic.

Operating principle of the comb

The comb window limiter is the most economical option sash opening restrictions.

The principle of operation is very simple: depending on the amount of fresh air you want to provide, the size of the gap between the sash and the frame is selected, a strip with slots is placed on the protruding pin of the lock.

The window comb can be installed on any plastic windows from any profile. And not just for windows! The comb can also be placed on the balcony door.

Why do you need a comb window stop?

A window sash limiter in the form of a comb (crocodile) is needed to limit the opening of the window sash. A window equipped with a comb can be easily locked in the open or ajar position. Fresh air will enter the room through the gap formed between the frame and the window sash. In this case, the comb will ensure rigid fixation of the sash in the position you need. This allows you to avoid strong drafts when ventilating the room, which is especially important in winter.

In addition, if you have pets like a cat who love to sit on the windowsills and look outside, then you simply need such a limiter. Through the narrow gap left by the limiter, your beloved animal will not be able to climb onto the ledge and leave you.

The comb sash opening limiters allow you to leave the fixed window sash unattended, without fear that a gust of wind will swing the window open.

Advantages of the comb

• low price
• ease of installation - installation does not require special skills
• installation “under the handle” allows you to install the “comb” limiter on both plastic and wooden windows
• opportunity to pick up suitable color- white or brown - depending on the color of your windows.

How to install the comb

To install a comb on a window, you must have on hand: at least one comb, 2 self-tapping screws, and a screwdriver.

If you forgot your screwdriver in the garage, you can use a regular screwdriver, as shown in our series of photos.

To install the comb on the window, you must first remove the handle from the window sash. To do this, turn the cover and unscrew the handle screws. One screw on top and one screw on bottom.

Then install the mating part of the comb with the rod on the handle.

Put the handle back in place.

Place the comb itself on the box opposite the mating part, located on the window sash under the handle, and mark the location of the screw with an orange felt-tip pen.

Secure the comb using two self-tapping screws and a screwdriver. Since the combs can be installed on plastic, wood or aluminum windows, you need to purchase screws yourself, based on the window material; they are not included with the combs.

As you can see, installing the comb on plastic window- The process is easy and takes very little time.
