Description

The utility model relates to devices for closing keyholes of level locks and relates to an overlay for a lock well, which can be installed both from the outside and from the inside of the door and can be widely used, for example, to prevent the ingress of dirt, dust and foreign objects into the lock mechanism.

A device is known for blocking a key well of a secret lock mechanism, which contains rollers spring-loaded in the direction of one another and mounted on an additional lock key (RU No. 2385401, IPC E05B 17/18 (2006.01), 2010).

The known solution has several disadvantages. Cylindrical rollers have a contact area tending to an infinitely narrow line, which increases the likelihood of a gap between them. Also, the rollers do not have seats for the spring, which increases the likelihood of skewing the rollers.

Known key lock, containing a lock, a cover mounted on the outside of the housing, a safety strip covering the cavity of the housing, key wells coaxially made in the housing, in the cover and in the safety strip, protective elements installed in the cavity of the housing. The protective elements are made spring-loaded with the possibility of blocking the key well of the casing, free from the key, and with the possibility of diluting the protective elements and opening the key well of the casing when entering the key. The housing has means for securing it outside the door leaf. The protective elements are made in the form of plates equipped with rods at opposite ends, coaxial, offset relative to the longitudinal axis of the plates and which are installed in grooves made in the housing. At least one rod for each plate is provided with a protrusion with a hole, one end of the spring is installed in the hole of the protrusion, and the other is mounted on a pin placed protruding in the cavity of the housing. The safety strip is mounted on the housing from the side facing the door leaf (see RF patent No. 2584668, IPC E05B 17/18 (2006.01), 2016).

This setup has a complex design due to the use of two curtains and a complex design to bring them into action, because springs used.

Known klyuchevina level lock containing a housing with a well under a level key. One shutter is installed in the body cavity, overlapping the borehole 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 when in contact with the key (see RF patent No. 180731, IPC E05B 17/00 (2006.01), 2018). This decision was made as a prototype.

The technical result indicated in the description for reducing the size of the clavine in thickness was not achieved, because the configuration of the curtains and the body does not allow achieving the declared result.

The technical problem solved by the utility model is to expand the arsenal of devices for protecting the wells of level locks while simplifying the design and reducing the thickness of the device.

The posed technical problem is solved due to the fact that in the well-known key lock of a level lock containing a body with a hole for a level key, in the cavity of which is installed with the possibility of rotation around its axis, the transverse axis of the well, the shutter overlapping the gap of the well from the inside of the body, in accordance with the useful model, the shutter is made in the form of a plate with lateral protrusions included in the vertical grooves of the body.

The grooves are made on the side walls located at the edges of the well.

The shutter is made in the form of a flat plate.

The shutter is made with a bevel in the lower part of the plate, on the side of contact with the key.

On the back side of the curtain, protrusions are made.

The technical result from the use of all the essential features of the claimed utility model is to reduce the thickness of the key, while simplifying the design and maintaining a high degree of protection of the lock mechanism from exposure to foreign objects, aggressive substances, as well as from dirt and dust entering the secret lock mechanism.

The implementation of the shutter in the form of a flat plate with lateral protrusions included in the vertical grooves of the casing can significantly reduce the thickness of the key, while simplifying the design and maintaining a high degree of protection of the lock mechanism from exposure to foreign objects, aggressive substances, as well as from dirt and dust entering the secret lock mechanism.

The side protrusions made on the flat plate of the curtain serve as an axis. When placing the protrusions in the vertical grooves of the body, the shutter has the ability to rotate around the protrusions (axis), and when exposed to it with a turned key, the shutter has the ability to climb along the vertical grooves, ensuring the key to move freely when opening (closing) and withdrawing it from the well.

The bevel on the contact bottom of the curtain contributes to a more active movement of the curtain up the grooves. The protrusions on the rear side of the curtain do not allow the curtain to move its center of gravity beyond the axis of rotation during rotation.

When you remove the key, the curtain returns to its original position under its own weight.

FIG. 4 - a key of a level lock in an open position, isometry;

FIG. 5 - case and curtain separately, isometry

The key lock of the level lock contains a housing 1 with a hole 2 for a level key. Along the edges of the borehole 2, side walls 3 are made in the body, forming a body cavity. In the upper part of the walls 3 there are vertical grooves 4 (see Figs. 1, 2, 4, 5). In the cavity of the casing 1, limited by the side walls 3, a shutter 6 is installed that can rotate around its horizontal axis 5, overlapping the borehole 2 from the inside of the casing (see Figs. 1, 4). The shutter 6 is made in the form of a flat plate with side protrusions 7 included in the vertical grooves 4, made in the upper part of the side walls 3 of the housing (see figure 5).

The shutter 6 can be made with a bevel (not shown conditionally) in the lower part of the plate located on the side of contact with the key.

On the rear side of the curtain 6, protrusions 8 are made.

Klyuchevina can be equipped with a decorative plate 9.

The device is assembled as follows.

The shutter 6 is installed in the housing 1 so that its lateral protrusions 7 enter the vertical grooves 4 made in the side walls 3 of the housing 1. The axis 5 of rotation of the shutter 6 should not be lower than the top of the well 2 under the leveling key. To facilitate assembly and compensation of possible technological defects during manufacture, the length of the vertical grooves 4 should allow the curtain 6 to rise up. The width of the grooves 4 provides free rotation of the curtain 6 around its horizontal axis 5. The housing is mounted on the door in a known manner.

The shutter 6 completely blocks the well 2 under the lever key, preventing mechanical and visual probing and evaluating the lock mechanism and the premises on the other side of the door, and also prevents dirt, dust and foreign objects from entering the lock mechanism.

When the key is removed from the well 2, the shutter 6 returns to its original position under its own weight.

In order that the center of gravity of the curtain during lifting does not go beyond the axis of rotation 5 (the curtain does not stick in the upper position), protrusions 8 are made on the inside of the curtain.

The proposed device allows to reduce the thickness and simplify the design of the key of a level lock, while maintaining a high degree of protection of the lock mechanism from the effects of foreign objects, aggressive substances, in particular, when trying to open them without a key and from unauthorized probing of the lock code, as well as from dirt and dust inside the lock mechanism with high reliability and durability of the protective mechanism.

The inventive device can be made of modern materials on existing equipment.

The utility model can be used for a wide range of doors, gates and other devices in which level locks can be installed.
