Abstract

A tumbler lock with a locking rail and at least one plate tumbler, wherein at least two separate zones with passage and release slots that differ from each other are provided and which are provided for interaction with at least two separate locking posts, which are mounted on a separate rotating element, which is mounted with the possibility of rotation on the locking rail, it is proposed that the proposed toggle lock provides a contact stop, which is made on the guide element in the area of the rotating element, Moreover, in the rotating element itself, opposite the contact stop, there is a contact engagement, which is made in such a way that when the locking rail moves in a straight line without rotating the rotating element, it passes alongside the contact stop without interacting with it, and when the rotating element rotates, the contact engagement, rotating, interacts with the contact stop and further rotates the rotating element, removing one of the two locking posts located on it from the plate tumblers.

Description

The invention belongs to the field of construction, in particular to the design of tumbler locks.

A tumbler lock with a reversible two-bit key is known, described in the OA patent

Mo 109384, in which two separate movable rails are provided in place of the usual locking rail: front and rear, each with its own push rail projections, and each with its own locking post. Also, in the tumbler lock there is an offset locking rail with a movement switch, which ensures engagement of the latter either with the front movable rail or with the rear movable rail. In addition, a toggle switch is provided in the toggle lock, which is partially located in the area of the key channel and is in contact with the motion switch. The plate tumblers for this tumbler lock are of a specific design, namely having two separate, distinct areas with release and passage slots for the first locking post and for the second locking post respectively, both locking posts being installed in the tumbler lock with the possibility of horizontal movement . This design of the tumbler lock works on the principle of alternating engagement of the front and rear movable rail with the offset locking rail.

At any initial position of the reversible double-bit key and during its subsequent rotation, only one of the two movable rails can move: either the front movable rail, interacting with the right driving tooth, or the rear movable rail, interacting with the left driving tooth. In the initial position, the offset locking rail is engaged, for example, with the rear movable rail. Then, when the reversible two-bit key in the tumbler lock is rotated from its original position, when the left driving tooth pushes the rear movable rail, the displaced locking rail also moves with it. With further rotation of the double-edged reversible key before the start of interaction of the right driving tooth with the front moving rail, for example, the left driving tooth presses the toggle switch, which, interacting with the movement switch, disengages the rear moving rail from the displaced moving rail and engages the latter with the front moving rail, and then at after further pushing with the right leading tooth of the front movable rail, the locking rail is moved together with the last one. At the end of this half-turn, the motion switch returns to its original position under the action of a spring. Thus, when moving both movable rails to a distance approximately equal to one half-turn of the reversible double-bit key,

The offset locking rail is moved a distance approximately equal to two half-turns of the reversible double-bit key. The front and rear sliding rails can be moved in any sequence. A reversible double-bit key can make any number of half-turns, both even and odd.

The main disadvantage of the tumbler lock of this design is its rather high complexity due to the presence of two separate movable rails and a movement switch, which itself also consists of several parts.

An anti-burglary tumbler lock is known, described in the application OA Mo a 201902001, in which at least one rotating element is provided, which is installed on a locking rail with the possibility of rotation and on which two blocking racks are located at the same time. This tumbler lock includes a housing in which the keyway is formed and in which at least one guide element is rigidly mounted, which fits into a guide slot provided on at least one plate tumbler, which is supported towards the keyway by means of a spring, and in which at least two separate zones are made, which in most cases are different from each other, with upper passage and release slots and lower passage and release slots to interact with the upper blocking post and the lower blocking post, respectively, which are installed in the rotating element, and between the upper the upper and lower tumbler teeth are formed by the through and releasing slots and the lower through and releasing slots.

When trying to open this tumbler lock with the help of a push-manipulation device, both locking racks simultaneously rest on the plate tumblers and try to squeeze into the corresponding upper and lower through slots. But since on one plate tumbler the upper and lower through slots are located at different heights, it becomes very complicated. But with repeated attempts, it still becomes possible, which is its main drawback.

The tumbler lock proposed in the invention is distinguished by the fact that it has a very high protection against opening with the help of any push-manipulation devices (locks).

The specified technical effect is achieved by the fact that the tumbler lock of the proposed design provides a contact stop, which is made on the guiding element in the area where the rotating element is located, and in the rotating element itself, opposite the contact stop 60, there is a contact catch, which is made in such a way that with rectilinear movement of the locking rails without rotation of the rotating element, it passes next to the contact stop, without interacting with it, and when the rotating element rotates, the contact hook, rotating, interacts with the contact stop, i.e., rotates the rotating element even more, diverting one of the two blocking racks located on it from the plate tumblers .

Next, the invention is described with the help of drawings, which are presented in figures 1-11.

Regarding fig. 1, 2 and C, the tumbler lock includes a housing 1 in which a key channel 2 is made and in which at least one guiding element 3 is rigidly installed, which enters the guiding slot 4, provided on at least one thrust plate tumbler 5, which is supported in the direction to the key channel 2 by means of a spring b, and in which at least two separate zones are made with upper passage 7 and release 8 slots, as well as lower passage 9 and release 10 slots for interaction, respectively, with the upper blocking post 11 and the lower blocking post 12, which are installed in the rotating element 13, and the upper toggle teeth 14 are formed between the upper through 7 and the releasing 8 slots, and the lower tumbler teeth 15 are formed between the lower through 9 and the releasing 10 slots. The rotating element 13 is installed with the possibility of rotation in the locking rail 16, which has located in the area of the key channel 2 at least one push rail projection 17. Also in the tumbler lock is provided with a contact stop 18, which is made on the guiding element C in the area of the rotating element 13, and in the rotating element 13 itself, opposite the contact stop 18, there is a contact catch 19, which is made below the contact stop 18 in such a way that with rectilinear movement of the locking rail 16 without rotation of the rotating element 13, it passes next to the contact stop 18, without interacting with it.

In addition to the thrust plate tumbler 5, the tumbler lock contains at least one coded plate tumbler 20, in which the upper tumbler tooth 14 is slightly distant from the upper locking post 11, and the lower tumbler tooth 15 is absent at all, and the lower passage 9 and release 10 slots about are combined into one continuous, horizontally enlarged release-through slot 21 opposite the lower locking rack 12.

Regarding fig. 4, 5 and 6 show the activation of the tumbler lock from the corresponding two-bit key 22, when during the initial rotation of the latter in the key channel 2, the stop plate tumbler 5 is set in the release position, when the upper release slot 8 is located opposite the upper locking post 11, and opposite the lower blocking post 12, the lower releasing slot 10 is located, at least one coded plate toggle switch 20 is also set in the releasing position, when the upper releasing slot 8 is located opposite the upper blocking post 11, and the releasing passage slot 21 is located opposite the lower blocking post 12, and movement of the locking rail becomes possible 16 in the horizontal direction together with the rotating element 13, since neither the lower blocking post 12 nor the upper blocking post 11 touch either the stop 5 or the code 20 plate tumblers. At the same time, the rotating element 13 does not rotate, and the contact hook 19 located on it passes next to the contact stop 18, without interacting with it, and further movement of the locking rail 16 becomes possible.

Regarding fig. 7 when the push-manipulation device 23 is inserted into the tumbler lock through the key channel 2 and the thrust plate tumbler 5 is installed in the release position, when the upper release slot 8 is located opposite the upper locking post 11, and the lower release slot 10 is located opposite the lower blocking post 12, the code plate toggle 20 remains in the position when the upper toggle tooth 14 is located opposite the upper locking rack 11, and the release passage 21 is located opposite the lower locking rack 12, since the upper toggle tooth 14 is slightly distant from the upper locking rack 11.

Regarding fig. 8 during further rotation of the push-manipulation device 23, the locking rail 16 continues to move in the horizontal direction and the upper locking rack 11 hits the upper rocker tooth 14 of the code plate rocker switch 20, only slightly touching the latter, while the lower locking rack 12 remains free.

Regarding fig. 9 during further rotation of the push-manipulation device 23, the locking rail 16 moves even further in the horizontal direction, while the upper locking rack 11 remains resting on the upper rocker tooth 14 of the code plate rocker switch 20, only slightly touching the latter, and the lower locking rack 12, remaining free , advances even further, while starting to rotate the rotating element 13 to the position when the contact hook 19 enters the zone of contact with the contact stop 18 and begins to interact with it.

Regarding fig. 10 during further rotation of the push-manipulation device 23, the locking rail 16 moves even further in the horizontal direction, the contact catch 19 of the rotating element 13 interacts with the contact stop 18 and further rotates the rotating element 13, diverting the upper locking rack 11 located on it from the code plate tumblers 20, since the distance from the contact catch 19 to the center of rotation of the rotating element 13 is less than the distance from the latter to the upper blocking rack 11. Further movement of the locking rail 16 in the horizontal direction becomes impossible, since the contact catch 19 is fixed in the contact stop 18, and the upper 11 and lower 12 locking racks are separated from the coded plate tumblers 20, which does not give any possibility to set the latter in the releasing position with the help of any push-manipulation device.

Regarding fig. 11 shows a variant of the tumbler lock, in which a retaining spring 24 is installed between the rotating element 13 and the locking rail 16, which only presses the rotating

From the element 13 to the locking rail 16, it prevents the accidental rotation of the rotating element 13 when unlocking with the help of the corresponding double-edged key 22, and, accordingly, the accidental blocking of the tumbler lock through the accidental interaction of the contact catch 19 with the contact stop 18.
