Description

LATCH FOR LOCK

The utility model relates to hardware, namely, to the design of the latch for the lock, designed to improve operating conditions and increase the security of the lock from unauthorized use.

As the closest analogue, the invention according to the British patent No. 2089417, MgaC E 05 B 19/06, publ. 1982. According to the invention, a leveling lock is patented, comprising leveling plates located on the crossbar, made with rectangular code grooves. The crossbar plate is made with attached bolts and a guide; with a pin fixed to the crossbar with the possibility of stirring; they can be inserted into the code grooves when interacting with leveling plates. In addition, the lock is made with a bolt; a Christmas tree mounted on a plate fixed with a key with the bolt bolts fully extended, turning the latch into an additional bolt.

The known design of the lock does not allow you to use the latch independently regardless of the main bolts, i.e. the latch cannot be used without locking the lock.

The task to which the utility model is directed is to expand technical capabilities by ensuring that the latch is used not only for its intended purpose, but also as an additional bolt of the lock, regardless of the operation of the main bolts.

The technical result consists in providing the possibility of locking the latch and turning it into a bolt by increasing the length and disabling the manual drive.

To achieve a technical result, there is a known latch for a lock containing a plate spring-loaded relative to the housing, on which a latch element is mounted, which is capable of locking a door and connected to a manual drive.

IPC EOS on 19/06

which secures a latch element that is installed with the possibility of locking the door and connected with a manual drive, characterized in that it is equipped with a controlled mechanism for converting the latch into a bolt, the driven element of which is connected to the p5D1NY drive with the possibility of increasing the length of the latch element to the size of the bolt and unlocking the manual drive with latch element.

In addition, the controlled mechanism for converting the latch into a bolt is made in the form of a rotary mounted two-arm lever, on one shoulder of which there is a groove with an eccentric located in it, controlled from the handle, and the second shoulder is placed in a groove made on a plate bearing a thrust element that is installed with the possibility of interaction with the element of the manual drive in the operation mode of the latch, while in the operation mode of the latch as a bolt, the thrust element is not connected with the element of the manual drive.

The above signs characterizing the construction of the code part of the level lock are essential and interconnected causally with the formation of a set of essential signs sufficient to achieve a technical result, in particular, to ensure that the latch is locked regardless of the state of operation of the lock.

The essence of the utility model is illustrated by drawings, where

figure 1 shows a General view of the latch for the lock in the operating mode "latch;

on Fig, 2 shows a General view of the latch for the lock in the operating mode "deadbolt.

The utility model is illustrated by a specific implementation example, which, however, is not the only possible one, but clearly demonstrates the possibility of achieving this set of essential features of a given technical result.

According to the proposal, the latch for the lock contains a plate 2 spring-loaded relative to the housing 1 (FIG. 1), on which a latch element 3 is mounted, which is capable of locking the door and connected to the manual actuator 4. The latch element 3 is a cylindrical rod with a bevel at the end, having two working plot: cylindrical 5 and beveled 6, the first is designed to operate in the "deadbolt" mode, and the second - in the "latch" mode.

To expand technical capabilities, the mechanism 7 of converting the latch into a bolt is made in the form of a rotary mounted two-arm lever, on one shoulder 8 of which a groove 9 is made with an eccentric 10 located therein, controlled from the handle 11, and the second shoulder 12 is placed in a groove 13 made on the plate 2. The stop element 14, mounted on the plate 2, is arranged to interact in the “latch” mode with the element 15, mounted on the support 16 rotary mounted in the housing 1, the lever handle 17 of the manual drive 4. In this case, turn the left handle 17 moves the latch element 3 inside the casing 1, when removing the load from the lever handles 17, the plate 2 with the latch element 3 under the action of the spring 18 returns to its working position. In the "deadbolt" mode, the latch element 3 functions as a deadbolt, and the thrust element 14 is brought out by the mechanism 7 from contact with the manual drive element 15.

The device operates as follows.

For the operation of the latch of the lock in the "deadbolt" mode, the control handle 11 of the conversion mechanism 7 is set to the "deadbolt" position corresponding to the arrangement of parts in Fig. 2. In this mode, the second shoulder 12 moves the plate 2 along the guides 19 with the possibility of increasing the length by size "A, transforming it into a deadbolt. In this case, the thrust element 14 is also shifted from the axis of rotation of the halyard handle 17 of the manual drive 4 and leaves the interaction with the element 15, i.e. the halyard handle 17 in the "deadbolt" mode retains angular mobility, but does not move the plate 2 with the latch element 3. Thus, the latch acts as a deadbolt controlled by the handle 11 mounted on the side of the lockable space. The design of the latch allows you to use it in combination with any lock, regardless of the design of its secret mechanism. At the same time, the latch can be used independently of the lock as an independent product.

To use the latch for its intended purpose, it is necessary to turn the handle 11 clockwise (Fig. 1) 180 ° to the “latch” position, while the eccentric 10 also rotates by this angle, thereby turning the two-arm lever, which, in turn, acts by shoulder 12 on the plate 2, moves the plate 2 to the right along the guides 19 in the position "latch. Moving the plate 2 to the right led to a change in the position of the stop element 14, in which the element 15 comes into contact with the stop element 15 under the action of the spring 18 in the direction of the doorway. In this position, the latch element 3 is reduced by the value of "A and only its working section 5 is working.

The use of a utility model allows to expand the technical capabilities of the latch.

The utility model meets the patentability condition “industrial applicability, since its implementation is possible using existing means of production using well-known technological operations. The manufactured prototypes confirm the possibility of achieving a technical result. 4
