RU180731U1 - SUVALD LOCK KEY - Google Patents

Abstract

A key-lock key is proposed, comprising a case 1 with a hole 2 for a level key, at least one shutter 4 is installed in the cavity of the case 1, overlapping the clearance of the well 2 from the inside of the case, characterized in that the shutter is mounted to rotate about its axis 5, the transverse axis of the well 6 to open the well in contact with the key. 3 s.p. f-ly; 8 ill.

Description

The utility model relates to devices for closing keyholes of level locks and can be widely used to prevent unauthorized probing of the lock code.

A device for blocking a key well of a secret lock mechanism is known, which comprises rollers installed directly in the secret mechanism and spring-loaded in the direction of one another, see US Pat. No. 5,934,121. The rollers block the key well. However, this solution has the following disadvantages. Since the rollers are located directly in the secret mechanism, this leads to its very complication. When trying to knock out the rollers, they can get inside the secret mechanism of the lock and cause it to break, and therefore to the subsequent emergency opening of the door, or the rollers can simply jam and to access the key well, it will be necessary to disassemble the secret mechanism.

There is a known key lock of a level lock containing a body with a hole for a level key, at least one shutter in the form of a roller is installed in the body cavity, which overlaps the borehole inside the body, see RF patent, 2385401 C1.

However, this solution has the following disadvantages.

The high cost of well-known klyucheviny due to the use of rollers. Used rollers that close the entrance to the lock well together with their coil springs take up a lot of space in the key, and if the key is also completely laid on, then when using it on a thick door, taking into account the thickness of the key, the key length may not be enough to insert it into Castle. In the event that the key is mortise, then under the rollers it is necessary to prepare a sufficiently deep and large diameter hole in the leaf of the sash. Known klyuchevina is not intended for mounting an external protective pad for a level lock.

The technical result achieved by the proposed utility model is the creation of keyword with reduced dimensions in thickness, which at the same time will make the keyword universal in application.

This technical result is ensured by the fact that the key lock of the level lock contains a body with a hole for a level key, at least one shutter is installed in the cavity of the body, covering the well clearance from the inside of the body. The shutter is mounted to rotate around its axis, the transverse axis of the well, to open the well in contact with the key.

The housing has a removable lid.

The shutter is spring-loaded with a spring element towards the well.

The body of the keyhole is provided with a cavity in which there is a reinforcing plate with holes for attachment to the wings.

The utility model is illustrated by drawings, which depict on:

FIG. 1 is a front view of the key, from the outside of the door;

FIG. 2 - klyuchevina assembled, rear view, well clearance closed with a shutter;

FIG. 3 is a section AA in FIG. 2;

FIG. 4 is a section BB of FIG. 2;

FIG. 5 is a section CC of FIG. 2;

FIG. 6 - complete key, rear view enlarged, well open;

FIG. 7 is a section D-D of FIG. 6;

FIG. 8 - curtain.

The key lock of the level lock contains a housing 1 with a hole 2 for a level key. The key lock of the level lock has a cover 3, removably mounted and located on the outside of the door. It can be of a decorative nature, but also protective when it is made of materials resistant to physical influences. In the cover 3, a hole is made for the key well 2. In the cavity of the housing 1, at least one shutter 4 is installed, overlapping the clearance of the well 2 from the inside of the housing. The shutter is mounted with the possibility of rotation around its axis 5, the transverse axis of the well 6 to open the well in contact with the key and close the lumen of the well when removing the key. The curtain in the latter case is rotated by its own weight. The shutter 4 can be spring-loaded (optional) by the spring element 7 in the direction of the well 2. Additionally, the key body 1 is provided with a cavity 8, in which there is an amplification plate 9 with holes 10 for attachment to the shutters.

The materials from which the elements of klyuchev are made:

The case is made of plastic, but there can be any other material.

The curtain is plastic, but there can be any other material.

The cover is stamped steel, but there may be another material - zinc alloy, or the same coated plastic.

The reinforcement plate is steel, but there may be other material.

Using Keyword.

We install the key in the door panel so that the axis of the key matches the axis of entry of the key into the lock.

In the working position, the shutter under its own weight closes the clearance through the borehole keyhole. But when the key is inserted into the borehole and contacts the shutter, the shutter rotates around the axis of the transverse axis of the borehole and opens the lumen and passage of the key through the borehole. In the case when the key is removed from the key, the shutter under its own weight rotates around its axis and closes the gap in the well.
