Description

The utility model relates to devices for closing keyholes of level locks and can be widely used in leveling keys of any design of a mechanism for closing a keyhole opening.

Known pad locks of various designs. The difference in the construction of the leveling plates is mainly in the technical solutions of the closing mechanism for the turnkey hole (hereinafter referred to as klyucheviny).

Known pads with movable spring-loaded elements moving along the axis perpendicular to the axis of the key installed in the key pad. Mobile spring-loaded elements can be made of various cross-sectional shapes.

Known keyword of the level lock RU 180731 U, publ.: 06/21/2018, containing a casing with a hole for a leveling key, one shutter is installed in the cavity of the casing, overlapping the clearance of the borehole from the inside of the casing, characterized in that the shutter is mounted for rotation around its axis transverse axis of the well to open the well in contact with the key.

When using lever locks with overlays in doors of large thickness, the distance from the hole of the key of the key to the hole of the key of the lock body becomes large and in order for the key to freely penetrate the key of the key and enter the key of the body of the key lock, a guide for the key should be made in the structure of the key. In the absence of a guide in the construction of the levers, the leveling key, when moving from the key of the leveling pad to the key of the body of the level lock, can easily change the direction of movement and will not fall into the key of the body of the lock.

To solve these problems, use the keys of a level lock with an integrated guide, for example, patents DE 3808560, publ.: 05.10.1989, WO 2009139007, publ.: 2009-11-19.

The closest is CH 450952, publ.: 05.15.1968. This solution is chosen as a prototype.

The technical problem of the prototype and other known solutions for a key lock of a level lock with an integrated guide is that such a key can be used for doors with a large thickness and cannot be used for doors with a small thickness. In doors with a small thickness, such a lever key rests against the lock body with its extension cord and does not allow the lever key to be fixed to the door leaf or requires a shortening of the lining guide.

In the conditions of mass production of entrance doors, it is inconvenient to use a wide range of levers with key mechanisms with different lengths or without a guide mechanism. It is much more convenient to have one model of a lever key with a removable key guide mechanism of a key of various lengths depending on the model of the door block (thickness of the door leaf).

In this utility model, a problem is proposed for solving this problem.

The technical result of the utility model is the implementation of a universal keyhole with removable guiding mechanisms of various lengths depending on the model of the door block (thickness of the door leaf).

The specified technical result is achieved due to the fact that the claimed key lock, containing a key guide fixed on the inside of the key body, in which a hole is made under the key key, characterized in that the key guide is removable and has a mounting base in the form of a plate moreover, on the inside of the keyhole, grooves and protrusions are made at the edges of the borehole under the leveling key, located around the edges of the borehole under the leveling key in such a way that passes into the grooves, and between the protrusions there is a mounting base of the key guide.

Preferably, the protrusions are located on two sides opposite each other, and the grooves are located on two other sides opposite each other, and one of the protrusions is made wedge-shaped.

Preferably, the grooves are formed by recesses of a thickening framing the body on the inside of the keyhole around its perimeter.

The body of the key can be made of metal or plastic.

Utility Model Implementation

The key lock of the level lock contains a key guide 3 for the key, fixed on the inside of the case 1 of the key. In the housing 1, a well 2 is made under a lever key.

What is new is that the key guide 3 is removable and has a mounting base 4 in the form of a plate. On the inner side of the keyhole, along the edges of the borehole 2, grooves 5 and protrusions 6, 7 are made for the leveling key. Grooves 5 and protrusions 6, 7 are located around the edges of the well so that passes into the grooves 5, and between the protrusions 6 and 7 there is a mounting base 4 of the guide 3 for the key, thereby providing the ability to remove and install the guide 3 of the desired length.

The protrusions 6 and 7 can, for example, be located on two sides opposite each other, and the grooves 5 are located on two other sides opposite each other. In this case, one of the protrusions 7 is made wedge-shaped.

The grooves 5 can be formed, for example, by recesses of the bulge 8, framing the housing 1 from the inside of the key, along its perimeter.

The case 1 of the keyword can be made of metal or plastic.

Guide 3 can be made of plastic, most often polypropylene. The manufacture of a guide 3 of plastic increases the thermal conductivity of the product as a whole.

When installing the lock in the door in the grooves 5 and between the protrusions 6, 7 of the key, a removable guide 3 for the key of this thickness is inserted, depending on the thickness of the door, which allows the guide 3 not to abut its extension into the lock body and secures the level key to door leaf without the need to shorten the guide 3. Thus, the claimed utility model reflects a universal key, with removable guide mechanisms of various lengths depending on the model of the door block (thickness of the door leaf).
