Limiter (latch) for opening the front door: characteristics and installation procedure. Locks for doors

Having started working in 2005, we could not imagine that we would be engaged not only in the installation of windows in St. Petersburg, but also in the repair of plastic windows, modernization, and the sale of fittings and window seals. Window seal and fittings are designed for a service life of about 10 years. In those days, there was no need to repair windows and sell spare parts for plastic windows in St. Petersburg. Of course, there was a need to adjust or lubricate the fittings, to eliminate the problem of double opening (the sash opens and reclines at the same time), but these were rare cases. Not many people know that window structures need to be serviced: adjust fittings, clean, lubricate the seal. It is advisable to carry out these service works annually, check the windows for operability, tightness. Over time, it became clear that everything around us in this world and windows also require maintenance. Now in 2019, no one will be surprised that it is necessary to adjust the windows, lubricate, and replace the seal. In the window industry, there is a wide variety of profile manufacturers and suppliers, it is worth noting that they all differ from each other. For example: the Rehau seal will not fit the KBE profile, the Roto NT fittings will not fit the GU. Windows are private. The window consists of four main components:

The profile from which the structure is made

Double glazing for thermal insulation

Fittings that allow you to open, tilt the window

Sealant for tightness

The main thing is to choose a good profile for the subsequent manufacture of a window structure, choose fittings, a double-glazed window and a sealant (German Schlegel Q-lon seals with a service life of up to 21 years have now appeared on the market). The second stage is the installation, where the window must be level, securely fixed in the opening. After that comes the installation of slopes, which not only perform an aesthetic, but also a thermal insulation task. It turns out 3 steps, each must be performed at a level so as not to get windows that will disappoint: they close poorly, blow through, whistle, etc. We advise you to contact trusted and reliable companies. We offer Rehau window structures using Roto Nt fittings, of course, you can save money and choose a technical profile and the cheapest fittings. It's up to you, we advise you to choose something in between, and not cheap or overly expensive.

We decided to modernize window structures, you know, it is almost always possible to replace a double-glazed window with a warmer one, install a triplex, tinted or armored double-glazed window in an existing window. But it is better to invite a window master, he will tell you exactly what to do, calculate the cost of completing the task. It is better to pay from 500 rubles to the master and find out exactly what is right to do. The experience of the masters of our company in the repair of plastic, wooden and aluminum windows has 12 years. Ask for help, advice or for a comprehensive solution to your problems.

Now the problem of ensuring the safety of children from falling out of windows is urgent, please do not delay the solution of this issue and familiarize yourself with the options to help keep peace and your family. You can find a handle with a lock, a child lock, a cable lock on the website and place an order for installation or purchase. You can install these security elements yourself, we recommend that you call us, we will solve this problem at a convenient time for you.

What is it needed for open position lock(abbreviated - FOP)? There are situations when it is necessary to fix the door in the open position, for example, in order to carry a load, so that a person with limited legal capacity can pass, so that a mother can carry a stroller with a child through the door, an orderly can carry a gurney with a patient, in a shopping center open the door to the full business day, etc. Suitable for such situations mechanical lock open position... Such latches are disconnectable and non-disconnectable, built into the closer and offered by manufacturers as an additional option to the closer.

Let's consider mechanical locks of the open position using the example of DORMA closers.

DORMA (with a lever in the form of a grasshopper's foot), like closers from all other manufacturers, do not have a built-in lock. The function of the open position lock is taken over by a special lever, supplied either as an option or already complete with a door closer (for example, DORMA TS 68 with FOP). Such a lever comes with the function of turning on / off the latch and with a permanently on latch.

FOP levers for DORMA door closers:

Similar to classic closers, they do not have a built-in latch of the open position, and only the DORMA TS 93 closer (and analogues from other manufacturers) has a built-in time delay function for closing the door, which is regulated by a special screw on the closer’s body and is somewhat similar to the function FOP... The clamps for these closers are supplied by the manufacturer as an additional option. The advantages of these clamps are that they are installed in the sliding channel of the closer, you can do this even after installing the closer and not buy a new lever, as is the case with classic closers. All FOPs for sliding channel closers have an on/off function.

Open position locks for DORMA door closers with sliding channel:

DORMA (and analogues from other manufacturers) are equipped with a built-in door lock in the open position with a certain locking angle of 90° or 105°, or they are available without locking. The built-in locking of the floor springs cannot be switched off, except for the BTS 80 model, where the locking can be turned on and off with a special screw.

DORMA floor springs with integrated hold-open:

For all closers using open position lock You can adjust the door fixing angle in the range from 80° to 120°. Exceptions are models BTS 60, BTS 65, BTS 75V, BTS 84 and their analogues.

In situations where doors must be kept open, and in case of fire, close to prevent the spread of smoke, fire and protect the room from oxygen, use closers with electromechanical locking of the door in the open position... Usually the control of these latches is connected to a fire alarm or smoke detectors. When the fire alarm is triggered, these doors will close immediately. Possible versions of door closers with electromechanical locking made of classic closers- DORMA TS 73 EMF and TS 73 EMR models (this model has an electromechanical lock and a built-in smoke detector). From door closers with sliding channel- models TS 93 EMF, TS 93 EMR and ITS 96 EMF. From floor closers- model BTS 80 EMB.

You can purchase any door closer with an open position lock from us. If you did not find the door closer model you are interested in, then send us a request by e-mail and our specialists will select the necessary door closer for you as soon as possible.

The ZE door hold-open device is designed to hold the door open at any opening angle. Retention is ensured by the departure of the crossbar to the required distance from the lower edge of the door to the floor level. The crossbar is always in a state of tension due to the action of the spring.

Clamps are available in five versions: bolt outlet is 25, 60, 75, 90, 160 mm. A latch with a 160 mm outlet can hold the door with a maximum distance from the bottom edge of the door to the floor level. However, the dimensions of this retainer are the same as the retainer with a 90 mm bolt outlet. Thanks to the use of an integrated spring in the heel of the bolt, the door remains firmly fixed even on uneven and polished floors.

All metal parts of the retainer are made of either aluminum or stainless steel, including internal parts. The pushbutton of the 25, 60, 75 and 90 mm models is made of rubber, while the 160 mm model is made of metal. The open position lock is ideal for use outdoors and in wet areas. The uniform design of the body and internal parts makes the ZE door lock a very reliable and durable device.

The standard version of the open position lock is painted with silver enamel. Other designs are available on request.

Installation:

When choosing the required model for installation on the door, you need to make sure that the crossbar reaches the floor. The open position lock ZE is installed on the door leaf at the maximum possible distance from the hinges (near the very edge of the door leaf). The tip of the bolt must be flush with the bottom edge of the door.

Fixing the door in the desired position is very simple; it is necessary to press with your foot on the upper stop of the crossbar of models with a reach of 25, 60, 75 and 90 mm, or on the metal ledge of the latch with a reach of 160 mm. The internal spring of the device will firmly fix the door in the open position.

To unlock the door, press the metal tab located under the upper stop. The piston will automatically release the spring to its original position, and the door can move freely.

The lineup:

A magnetic door latch often becomes an actual solution to everyday problems. Thanks to this design, it is possible to protect households from injuries that can be obtained if the mechanism closes abruptly due to a draft. Thus, the limiters will extend the durability of the door structure, protecting it from impacts. Before purchasing a magnetic latch for interior doors, you need to familiarize yourself with the varieties, features and other parameters of this product.

Magnetic stop option for interior doors

Everyone has their own motives for purchasing a door stop with a magnetic lock. This element will increase the level of security of the walls, the door structure itself, as well as the residents of an apartment or house.

It is worth installing a latch for the following reasons:

These are the main reasons why you need to install a magnetic latch. Each person has their own motives and preferences for arranging such a mechanism.

Scope of application of magnetic clamps

Products such as magnetic latches can be used in different rooms, regardless of their purpose. If there are openings in the space leading to other rooms, then the restrictive metal strips can find their place in it.

Variant of the design of the magnetic retainer

The choice and installation of latches for doors is most often carried out:

representatives of educational institutions;
owners of entertainment establishments;
medical personnel;
owners of country houses or apartments.

Looking at the above information, you can understand that there are no specific establishments in which door latches are most often installed. Such elements for safety and comfort are used everywhere.

Magnetic retainer option

Analyzing the statistics of demand, the staff of building stores claims that the number of people wishing to purchase a structure opening limiter in a set for the door leaf is increasing every year. At the same time, different types of products are purchased.

Types of magnetic clamps

To choose the door opening limiter accurately, you should study what types they are in general. There are two main types of magnetic clamps by type, and their installation location also varies:

The principle of their work is similar, but still there are some differences. People who go to the store to buy this product should be aware of these differences.

Dimensional drawing of magnetic retainer

Floor fixer

There may be floor stops. Such clamps are most common among consumers. Regardless of which door the element for the PVC loggia or for the bedroom will be installed with, its location is behind the door.

Instructions for mounting the floor magnetic fixer

The floor clamp performs two functions at the same time. The first of these is to control the degree of opening of the door leaf sash. At the same time, the limiter is an element that holds the door in a single position when open.

The principle of operation of the floor clamp

At the same time, at the installation stage, it is necessary to determine the angle of the door in the open position in order to correctly fix the stopper.

wall bracket

According to the principle of its action, it is similar to the floor element limiter. The only difference between the wall limiter is the installation technology.
See in the video the equipment and operation of the magnetic lock for the door.

You are tired of loudly slamming doors and impartial chips on the walls left by the door leaf, so it's time to purchase and install a door opening limiter. Next, we will analyze in detail the types of such devices, and finally we will show how to install a door stopper with your own hands.

Door opening limiters are quite diverse.

The stool pushed under the door and a homemade wooden wedge are slowly disappearing into history. Now the industry produces a wide variety of stops, which are sometimes difficult to understand.

Limiter classification

In fact, the door stop is one of the varieties of small fittings. Doors are divided into entrance and interior doors, the weight and dimensions of the canvases can vary greatly, respectively, and the stops on the door are different.

In addition, door stops can perform different, sometimes opposite, functions. It’s one thing when you need a stop so that the canvas doesn’t hit the wall, and it’s completely different when you need to protect children’s fingers from a door that doesn’t close at the right time.

But how to make the right choice, if often an ordinary person has a rather vague idea of what kind of mechanism he needs. First, let's go over the basic terms.

Original door stop design.

Stops - designed to limit the angle of the door turn, and sometimes fix the door leaf at the end point when in contact with the stop;
Chips - are needed to soften or prevent the impact of the door leaf on the wall or any other object, for example, furniture;
Stoppers - these structures must rigidly fix the canvas at a certain point. The most prominent representative of stoppers can be called a well-known chain;
Overlays - prevent the door from completely slamming, leaving a small gap between the jamb and the door leaf;
Latches are, in fact, a kind of lock, the latch fixes the door in the closed state. There is still no consensus among experts whether to refer latches to locks or still to stops;
Closer - as a rule, this is a limiter for opening the front door. The direct purpose of the closer is to ensure smooth closing of the doors, but there are models that allow you to fix the canvas open at a certain point.

Many modern closers can be adjusted locally.

Despite the variety of terms and countless models, all these designs are divided into 3 fundamental areas:

Limiters installed on the floor;
Limiters mounted on the wall;
Limiters installed on the door itself.

Floor models

A floor stop for a door is perhaps the most reliable option, because the floor is static, it will not go anywhere, plus the price of most floor models, as a rule, does not “crawl out” beyond 200 rubles.

The color of the permanently fixed post-post should be in harmony with the overall design.

Metal stops-columns are stationary limiters that are rigidly attached to the floor. The height of such an emphasis ranges from 3 to 7 cm, the average cylinder diameter is 20 - 30 mm. In order not to "cripple" the door on the column there is a groove with a rubber or polyurethane seal.

With proper installation, the column itself does not threaten anything, but the seals will have to be changed periodically. In the residential area of an apartment or a private house, it is better not to put columns, since it is easy to stumble on them, but as a limiter for opening the front door, the column fits perfectly.

When choosing such a column, it is better to give preference to shiny and contrasting models. They are at least visible from afar and less likely that a person will stumble.

Semicircular door stop.

The semicircular door opening limiter looks like a quarter of a dissected ball with a shock-absorbing gasket. There is no fundamental difference in the operation of posts and semicircular stops, but when installing the latter, the installation angle must be taken into account so that the door leaf comes into contact with the rubber gasket and does not hit the metal.

The magnetic door stop keeps the door open.

A door stop equipped with a magnet is already a more functional design. A small magnet is built into the head of the stationary stop, and a counter metal plate is attached to the door, as a result, the door leaf is fixed when it comes into contact with the stop.

Of course, magnetic structures are not suitable for entrance doors, because the strength of the magnet is not enough to hold the canvas in gusts of wind, but in the room such stops work flawlessly.

Cork stops are only suitable for the corresponding design.

Cork, rubber and polyurethane stops are a variation of the same posts, the difference is only in the material. But before you put such an original emphasis, you need to think carefully, because a soft limiter is not a guarantee that you will not “beat off” your fingers about it, plus the cork is practically invisible on the carpet.

The ability to close the head of the stop in a latch mounted on the door jamb is quite a useful feature. Especially well, such devices have proven themselves on the front doors of offices, administrative buildings and shops, in general, wherever a simple latch can pop out by negligence or from a gust of wind.

The spring stopper is a good solution for temporarily fixing the door leaf.

The design solution is ingeniously simple: synthetic anti-slip "hedgehogs" are fixed on both sides of the flexible steel plate, you only need to slightly bend the plate and slide it under the doors.

Such a device is well suited for temporarily fixing doors, for example, if you need to bring furniture. With this emphasis, even if the door moves from an accidental push, expensive laminate or parquet will remain intact.

The wedge retainer is the simplest solution to the problem.

Wedge-shaped or as they are also called, mobile clamps are now made from different synthetic materials, but in fact these are the same wooden wedges that our grandfathers inserted under the doors, only the external surroundings have changed. Although synthetics must be given credit, such a door stopper does not slip on the floor.

The signal limiter can become the last bastion on the way of robbers. Cheaper models simply make a loud sound when the door leaf comes into contact with them, and the "advanced" stops silently send a radio signal to some kind of receiving device, for example, to a mobile phone or a security console.

wall models

Installing a door stop on a wall is an excellent solution for rooms where, for one reason or another, it is not desirable to fix the device to the floor, for example, expensive floor coverings, such as marble or natural parquet.

Classic wall stop for a door.

The cost of wall fixtures starts from 150 rubles, although this is not a lot, but still more than floor limiters.

The market leader here is a standard stop with a platform and a rubber shock absorber mounted on top of a metal rod. It is distinguished from the floor version of cork by the presence of a wider support platform and a stem with a length of 5 to 15 cm.

When choosing, you need to consider what material your wall is made of. There is no difference for monolithic brick or concrete walls, but for drywall you need to buy a device with a wide mounting platform (at least 100x100 mm), otherwise the GKL will simply break through from a point impact.

The simplest wall limiter with fixation on self-tapping screws.

The wall-mounted version of the magnetic device may differ from its floor-mounted "brother" only in the length of the stem, otherwise they are identical.

Often there is no way to fix the limiter on the floor, and rubber shock absorbers with a rod leave hard-hitting marks on the door leaf. In this case, a soft pad on the wall under the handle will help you.

Soft synthetics will smoothly absorb the blow, you don’t need to drill a wall to mount the stop, just stick the fixture on double-sided tape, and most importantly there are a lot of design options and choosing a model for your interior is not difficult.

Soft model with support under the handle

There are in the line of wall fixtures and stops with a reliable lock. As shown in the photo below, the mechanism itself is attached to the wall with self-tapping screws, and the hook with the platform is screwed from the bottom end on the door leaf.

The principle of operation is simple: a rounded door hook, approaching the stopper, lifts the movable part and, thanks to the spring, the latch clings. The only inconvenience is that to release the doors, the latch will have to be pushed back manually.

Wall version of the stop with a latch.

Door fittings

The beauty is that if we are talking about wooden or plastic doors, then you only need a screwdriver to fix such a limiter, and in some cases you can get by with one glue. Plus the walls and floor will remain intact.

In folding metal stops, the base plate is screwed to the door leaf with self-tapping screws, but during installation, you need to carefully consider setting the angle of inclination of the limiter relative to the floor, an acute angle can cause the mechanism to break. The optimal slope is around 45º.

In addition, when choosing, it is better to give preference to mechanisms in which there is a folding spring, they are an order of magnitude more reliable.

Folding metal overdoor limiter.

The tape stop can be safely called a symbol of simplicity. Self-tapping pads are attached on both sides of the strong tape, you just need to screw these pads to the doors and the jamb.

True, the appearance of this limiter leaves much to be desired, plus such tapes fray or tear rather quickly.

If you still decide to buy a tape stop, then it is better to choose elastic stretchable models, their price is not much higher, but such stops are more convenient to use.

Tape stop is considered one of the simplest and most affordable options.

The retractable overdoor stop is a rod with a kind of brake shoe. It is installed in a vertical position and you yourself can decide where exactly to fix the structure.

The retractable overdoor stop is a fairly compact and convenient device.

The sliding model is designed to rigidly fix the door leaf at certain points, there may be several points, it all depends on the number of cutouts in the solid base groove.

This device cannot be called completely over the door, since the base part with a groove is attached to the door jamb, and only the movable stem is fixed on the canvas. Although this is not essential, on some models the fasteners can be interchanged.

The undoubted advantage of such an emphasis is the installation at the top of the doors, where it does not interfere with anyone. On the other hand, to release the stem from the locking groove, you will have to reach it, which is not always convenient.

One of the popular models of sliding stop.

Soft slips protect a door from slamming. These devices are especially convenient in children's rooms, with such pads your child's fingers are much less likely to be squeezed in the door. There is no need to talk about installation at all, the rubber band is simply put on the door.

The soft slip is designed to protect the doors from accidental slamming.

Installation technique

Installing a door stop is pretty easy. We will not talk about gluing options, you can handle this yourself, as for fixing to screws, the instructions are something like this:

We install a door with a gap between the handle and the wall of about 20 mm and mark the position on the floor;
According to the mark on the floor, set the emphasis at the desired angle;
We drill a hole for the dowel for the self-tapping screw and insert the dowel itself;
We fasten the stop with a self-tapping screw to the floor.

Wall and door opening stops are mounted in approximately the same way, so there is no point in retelling this simple instruction.

Conclusion

We tried to most fully reflect all types of door stops. Watch the video in this article for more information on this topic.
