Abstract

Toggle lock with a locking rail and a housing in which a key channel is made and in which at least one guide pin is rigidly inserted into the guide slot provided on at least one plate toggle switch having at least two separate zones with through and release passages , which differ from each other and which interact with at least two separate locking struts, where the toggle lock provides at least one contact element, which is mounted on a locking rail with the possibility of rotation, and both locking struts are located on one contact element.

Description

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

A tumbler lock is known, described in patent OA Mo 108978, which provides a locking rail, which is remote from the area of rotation of the key in the key channel, and spring-supported plate tumblers, which have zones with specific slots for interaction with the locking rack located on the locking rail, and the plate tumblers are installed with the possibility of rectilinear movement along at least two guide fingers, which are located in the guide slots on the plate tumblers, and with a movable element that is installed with the possibility of displacement under the action of a separate, spring-supported pushing device, which is not rigidly connected to the closing rail, has at least one control protrusion that extends into the area of rotation of the double-bit key, and is installed with the possibility of rotation relative to the movable element, and the movable element is located in the body of the tumbler lock, or in its fixed parts, without the possibility of rotation, at least on one side relative to the direction own movement has at least one pointed end, according to which at least one plate tumbler is provided with at least one corresponding locking notch.

In this tumbler lock, when an attempt is made to open it with the help of a special push-feeling device introduced through the key channel, correctly and incorrectly installed plate tumblers are blocked equally due to the fact that the movable element has the ability to move under the action of a separate push device, for example: a lever, and its pointed finally enter the blocking recesses.

The main disadvantage of the tumbler lock of this design is the need for a lever, when using which the load on the double-bit key increases, which leads to its rapid wear.

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. Additionally, the tumbler lock is provided

Zo is located partially in the area of the key channel and the switching toggle switch 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 interlocking post and for the second interlocking post, respectively, and both interlocking posts are 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. On further rotation of the reversible double-bit key before the right-hand drive tooth begins to engage with the front moving rail, for example, the left-hand driving tooth depresses the toggle switch, which, interacting with the motion switch, disengages the rear moving rail from the offset moving rail and engages the latter with the forward moving rail, and then with further pushing with the right leading tooth of the front movable rail, the displaced locking rail moves together with the latter. At the end of this half-turn, the motion switch returns to its original position under the action of a spring. Thus, when both movable rails are moved by a distance approximately equal to one half-turn of the reversible double-ended key, the displaced locking rail is moved by a distance approximately equal to two half-turns of the reversible double-ended 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 motion switch, which itself also consists of several parts.

The tumbler lock proposed in the invention is distinguished by the fact that it has an extremely simple design and can work when a suitable ordinary two-bit key is inserted into the key channel in any position with the possibility of its further rotation by a certain number of half-turns and displacement of the locking rail by a certain distance, and this the tumbler lock has a sufficiently high protection against opening with the help of any push-feeling devices (keys).

The specified technical effect is achieved by the fact that in the tumbler lock of the proposed design, at least one contact element is provided, which is installed with the possibility of interaction with two locking racks at the same time, and the contact element is installed on the locking rail with the possibility of rotation.

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 body 1 in which a key channel 2 is made and in which at least one guide finger 3 is rigidly mounted, which enters the guide slot 4 provided on at least one plate tumbler 5, which is supported in the direction of of the key channel 2 by means of a spring b, and in which at least two separate zones are made, which in most cases ARE different from each other, with the upper passage 7 and the release 8 slots, as well as the lower passage 9 and the release 10 slots for interaction with the upper by the locking rack 11 and the lower locking rack 12, which are movably installed in the contact element 13 in the upper 14 and lower 15 contact slots, respectively, and the contact element 13 itself

Zo 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 protrusion 17. Since the contact element 13 has sufficiently large dimensions, the locking rail 16 cannot be directed relative to the guiding finger 3, and for this in the tumbler lock a guide plate 18 is provided, which is contained simultaneously in the guide rail groove 19 and in the horizontal grooves 21 made in the body 1 and in the cover 20 of the body, and to stabilize the locking rail 16 from lateral displacement, bent elements 22 are provided on the guide plate 18, which are in free in the space between the locking rail 16 and the housing cover 20 and between the locking rail 16 and the housing 1. To prevent the interaction of the guide plate 18 with the plate toggle switch 5, a through toggle groove 23 is provided in the latter. To prevent the interaction of the guide finger Z with the contact element 13 during its movement and rotation in the last before a rotary-through groove 24 is visible. To ensure rectilinear horizontal movement of the upper 11 and lower 12 locking racks during rotation of the contact element 13 in the housing 1 and in the cover 20 of the housing, the corresponding upper guiding groove 25 and lower guiding groove 26 are provided.

Regarding Fig. 4 and 5, the activation of the tumbler lock from the corresponding two-bit key 21 is shown, when during the initial rotation of the latter in the key channel 2, the plate tumbler 5 is set in the position when the upper release slot 8 is located opposite the upper locking rack 11 and it becomes possible to move the locking rail 16 and the upper of the locking rack 11 in the horizontal direction, and the lower locking rack 12 remains resting on the plate tumbler 5 and when the locking rail 16 moves, the contact element 13 is rotated clockwise.

Thus, plate tumbler 5, when positioned correctly, when there is a release slot opposite one of the locking racks, remains blocked by another locking rack, which provides a sufficiently high protection of this tumbler lock against opening with the help of any push-manipulation devices (keys). At the same time, it does not matter which of the two locking racks is locked, and opposite which is the releasing slot. That is: the movement of the locking rail 16 becomes possible also in the position when the upper locking rack 11 is resting on the plate tumbler 5, and opposite the lower locking rack 12 is the lower releasing slot 10 (not shown in Fig.).

Regarding Fig. b, upon further rotation in the key channel 5 of the corresponding two-bit key 27, its other prong sets the plate toggle switch 5 in a position where the lower release slot 10 is located opposite the lower locking rack 12 and further movement of the locking rail 16 and the lower locking rack 12 in the horizontal direction becomes possible , and the upper locking rack 11 remains resting on the plate tumbler 5 and when the locking rail 16 moves, the contact element 13 is rotated counterclockwise.

Regarding Fig. 7, 8 and 9, another version of the proposed tumbler lock is shown, in which the upper 11 and lower 12 locking posts are rigidly fixed to the contact element 13.

This design is much simpler, but with this design, the two-bit key 27 must be inserted into the key channel 2 only in the appropriate position. In this version, the tumbler lock works in the same way as indicated above, but the upper 8 and lower 10 release slots are made circular, because when the contact element 13 is rotated, both locking racks 11 and 12 also move in a circular direction. Therefore, a variant of the proposed tumbler lock (not shown in Fig.) is possible, in which only one, the upper 11 or the lower 12 blocking post is rigidly fixed, and the other remains movable.

Regarding Fig. 10 and 11, shows the additional protection of the tumbler lock against opening with the help of a corresponding push-manipulation device 28 inserted through the key channel 2, which is achieved by the fact that above the upper 25 and lower 26 guide grooves, or only one of them, in the housing 1 and an upper additional groove 29 and a lower additional groove 30 are made in the cover 20 of the case, which make it possible for the upper 11 and lower 12 locking racks, or one of them, to move in the vertical direction during manipulation attempts to lift the plate tumblers 5, when the upper 11 and lower 12 locking racks racks, or one of them, are persistent in plate tumblers 5. To return the upper 11 and lower 12 locking rack, or one of them, to the initial position in the tumbler lock, at least one contact spring 31 is provided.
