Locks to prevent doors from closing: types and features


Few people like loud slams of doors and walls broken by door handles. To avoid these minor troubles, a door opening limiter was invented. Let's try to understand the types and purposes of such mechanisms, and for dessert you will learn how to install a door stop with your own hands.

Door opening limiters have always existed in one form or another, but over the past half century the range of these accessories has grown hundreds of times.

Closed position latches

Such devices limit the opening of doors. They are used in residential buildings for doors dividing rooms and leading to the balcony, as well as in crowded places: shopping centers, supermarkets, etc.

Ball (roller)

Installation is carried out on both sides of the door. One part of the mechanism is attached to the end of the door leaf, and the second - to the door. When installing, be sure to maintain the same level. The mechanism works by fixing the tongue ball in a special hole on the opposite side. The reliability of this device has been proven by a long period of trouble-free use.

The convenience of using the mechanism lies in the ease of installation. Installation does not involve removing the door lock or handle. Ball latches operate independently of the door handle. This advantage is used in areas where there is a need to keep doors closed.

False

This type of latches differs from ball latches in that they depend on the door handle when opening. The mechanism operates by inserting a beveled tongue into a similar hole on the side of the box. The door opens when the handle is turned.

The device securely holds the door leaf even in strong drafts or when a child tries to open the door. Installation of the door mechanism leading to the balcony requires the installation of a double-sided handle for free exit from the outside.

Hinged latches do not require a regular door handle. The devices serve as its replacement. During installation, you should discuss with the manufacturer the possibility of installing the mechanism.

Trouble-free operation of the device depends on correct installation. The tighter the door fits, the more reliable the system. Sagging doors are the cause of halyard latch failure. The problem will disappear after adjusting the hinges.

Types of products and their features

I will talk about three product options:

  • Floor opening limiters;
  • Wall products;
  • Over-the-door options.

Floor type limiters

This is the most common and popular option and has several advantages:

  • Huge variety . There are a lot of design options; they can have different sizes, colors, and designs. This allows you to choose the optimal solution for any interior;

Magnetic latches

Devices for plastic doors look like magnetic plates mounted on the door frame and leaf. During operation, the metal does not deteriorate because there is no friction. Sometimes demagnetization occurs. During normal use, this hardware is considered one of the most durable.

For doors with handles, magnetic latches provide quiet and secure operation. The devices are characterized by easy installation and excellent holding function. Fastening occurs without strict adherence to the installation level. The installation location is chosen arbitrarily. Sagging of the sash will not affect the function of the magnetic lock. Reliability and ease of use are the main advantages of clamps.

Making a door stop with your own hands

If you wish, you can make a door stop yourself. The construction of a soft restrictive device is based on the manufacture of a small pupa (tilde) and a filler. To increase the weight of a homemade interior door stop, you will need sand or small pebbles.

The door stop is located on the handle on the opening side of the door leaf. The locking device must have a loop. Everyone determines the color and design of the tilde at their own discretion. Ready-made patterns can be found on the Internet or in magazines.

To make the device you will need the following consumables:

  • Pin;
  • Textile;
  • Threads matching the color of the fabric;
  • Soft filler, for example, synthetic winterizer.

First of all, you need to focus on the volume of the tilde. It should be enough to soften the impact of the blade when opening. Each individual element is cut out in 2 copies. The cut blanks are stitched together, leaving a small section unsewn to fill the volume with filler. Next, you need to unscrew the components of the future interior door stop, fill them with padding polyester or other soft material, and completely sew them up. The homemade door travel stop is ready, all that remains is to install it on the door structure.

Opening limiters

This type of mechanism is represented by wall and floor limiters. The peculiarity of the work is that it is securely fastened at the base of the leaf, which does not allow the door leaf to open fully in the future. When installing fixing devices, the wall covering and furniture will be protected from possible mechanical damage. In situations where it is not possible to install a limiting mechanism on a wall or floor, fastening is carried out on top of the door frame. The stop of the latch will be directed towards the stopper installed on the door slope. This type of installation can cause problems as there is a risk of damage to the slope due to its fragility. A sudden opening will result in defects.

Kinds

Small mechanisms that can be installed on or under a door to limit opening are called technical locks.

Based on the mounting location, devices are divided into:

  • opening limiters. Keep the door closed, protecting against arbitrary opening;
  • floor Using wedges, the specified position of the web is ensured;
  • wall-mounted Protect the wall surface from possible impacts with a handle;
  • over-wall. Ensure smooth door movement and closing.

Stoppers

These devices are used in residential premises, as well as in industrial buildings and public institutions. These mechanisms are inexpensive and small in size. The use of clamps has a number of positive aspects, namely:

  • safe presence of children in the room when there is a need to leave them unattended for a short time;
  • free movement of pets from room to room without the risk of injury from being hit by the door;
  • locking the door in case of oversized items entering;
  • safety of the wall and nearby furniture from accidental damage due to careless opening of doors;

Installation

The floor door opening limiter is installed in several stages. So, at the first stage, the necessary tools are prepared. This is a hammer drill, drill, screwdriver and marker or pencil. When purchasing a product, it is important that it is equipped with special fasteners.

At the second stage, you need to select a suitable location. The main thing here is to choose exactly the right place. To do this, open the door leaf and then fix it in such a position that about 5 cm remains from the door to the wall. At the same time, make sure that the distance from the door to the wall is no less than the length of the door handle, otherwise the stop will not work. If the product will be installed in a walk-through room, then it should be mounted as close to the wall as possible.

Next is the marking stage. At this stage, mark the place where the device will be placed. Then two holes are drilled in the floor - one for the dowel, the second for the pin. A dowel is hammered into one of the holes and the products are installed in this place. It is important that the pin also fits into the second hole. Then you can fix the element.

Limiters are very useful and practical products. They protect walls and furniture without worrying about children's fingers or pets.

Installation details

You can install limiting devices yourself, since manufacturers equip the fittings with the necessary mounting holes.

The following tips will help you properly attach the fasteners:

  • do not install the mechanism at the level of the door hinges;
  • choose a place closer to the end of the canvas. This way the doors will last longer and will not be damaged by impacts;
  • pay attention to the size of the handle. The latch should not allow the wall to come into contact with the handle.

Installation of floor limiters is carried out according to the following recommendations:

  • wide passage. Do not install the clamp in the path of people;
  • Maintain maximum proximity to the end when installing the clamp. This will preserve the integrity of the door leaf longer;
  • Consider the dimensions of the handle. Failure to comply with the dimensions will result in damage to the wall.

Attaching the limiting devices is not difficult. Installation of clamps occurs according to the following plan:

  • Selecting the location of the fastener and making marks with a pencil at the designated points.
  • Drilling holes for dowels in the marking areas.
  • Fixing the device on the wall or floor using self-tapping screws.
