Door hardware - how to protect yourself and add functionality to doors

There is no stupid thing than a door without a handle. Even the grandmother from a famous fairy tale tied a rope to her to open. Surely there was simply no furniture store in the village with a catalog of door hardware, otherwise the grandmother would have bought a reliable lock and a peephole with a good view and a strong chain. And she would live and live without fear of wolves from the forest.

Types of fittings

Fairy-tale times are long gone, and the problem of uninvited guests will remain relevant for a long time. In a modern apartment or house, the doors, in addition to ensuring security, should be convenient and functional. For all this, the door fittings are responsible:

pens;
locks;
peephole;
chain;
the closer.

We begin the review with the most necessary - with door handles.

Doorknobs

This type of hardware differs in its form and principle of operation, as well as in the material of manufacture. Experts advise choosing them based on the purpose of the door - entrance, interior, bath; ergonomics and mechanism of action of the handle itself. There are three types of handles according to the principle of action:

stationary;
file with pressure;
falevy with a turn.

Stationary handles do not have a latch mechanism and serve only to pull them, opening or closing the door. They are fastened with screws or screws. Handles with a push mechanism have a latch in the door leaf. When the handle is pressed, the spring moves the latch, freeing the door. Handles with a rotary mechanism are spherical or elongated. In the center of it there may be a keyhole, and on the reverse side there is a blocking button. Such handles are convenient for rooms and bathrooms. For the manufacture of door handles, the following materials are usually used:

metal;
plastic;
tree;
glass.

Metal - the most reliable and durable. They are made of stainless steel, aluminum, brass and various alloys. High decorativeness and respectability are distinguished by forged handles. Plastic is sold in a huge assortment, they are cheap, but have less strength. Plastic handles are placed where the door leaf does not exert much effort. Wooden is usually selected for the appropriate interior or for a bath. Wood furniture looks stylish in various ethnic styles - country, rustic, Scandinavian. Good for classic, victorian and provence style. For baths and saunas, only wood is used, since any other materials either heat up very much, which can lead to burns, or can be deformed by the action of temperature. Glass pens are made from Murano or Bohemian glass.They are selected for other details of the situation. The door handles made of natural stone look luxurious. Usually they are decorated with carvings or cuts.

Locks

The lock is the second most necessary part for the door leaf. They vary in appearance, locking mechanism and degree of reliability. The most inexpensive and simple types are suitable for interior doors, the options are selected more seriously for the entrance doors, and the most powerful ones are put on safes and rooms with increased security requirements. Door locks according to the installation method are of the following types:

mounted;
waybills;
mortise.

According to the locking mechanism, they are divided into crossbar, electronic and code.

Door eyes

A peephole is usually completed with an entrance door in apartments where there are children and elderly people who are easy to mislead. Yes, and adults sometimes do not bother to make sure that the appearance of the postman corresponds to his angelic voice, and a couple of his assistants are not hiding behind him. We owe the creation of the door eye in its modern form to Robert Wood, an American scientist. It was he who invented the fisheye optical lens. It gives the largest viewing angle - the main characteristic of good door peepholes.

Closers

The door closer serves only for smooth movement of the door when closing. They are most often installed in public places and offices with high traffic, so that the sound of a slamming door does not irritate or distract employees. Closers are of three types:

top
floor;
hidden.

Closers consist of two main elements - a spring and a shock absorber. The spring, while straightening, helps to close the door, and the shock absorber gives the movement smoothness and noiselessness. Properly selected and correctly installed door fittings will perfectly fit into the interior, enhance security and add comfort to the room.
