Abstract

Use: in devices for locking doors, in particular for locking doors of garden houses, garages, sheds, lockers for personal belongings and clothes in production premises of enterprises, etc. The essence of the invention: the lock contains a hollow body, a sleeve installed in the body with rotatable by 90 °. The hub has a central seat under the hinge lugs. The locking member is located in coaxial bores of the sleeve, communicating with its central socket. The rotary axes are evenly spaced around the circumference of the lock case with the cams attached to them having code elements. Fixed coded elements are installed in the sleeve, spring-loaded from the center of the lock by flat springs. The locking elements interact with the code elements of the cams. 7 il.

WITH

The invention relates to devices for locking doors and can be widely used in various fields.

The closest to the proposed technical essence is a lock containing a cylindrical body, at the base of which are mounted rotary axes with code disks (cams), each of which has a protrusion at the periphery and a glass (sleeve) having cut-outs at the base, made in accordance with the protrusions of the code disks, and the body and the glass have annular recesses in which the code disks are located.

The disadvantage of the known lock is that it is inconvenient to use and all operations on the use of the lock are carried out with two hands.

The aim of the invention is to improve the usability

The goal is achieved by the fact that in a known lock containing a hollow body, the rotary axes with cams having code elements installed in the body cavity can be rotated bushing with a central slot for locking door ears and communicating with the socket radial holes , a locking member located in the radial holes of the sleeve and arranged in accordance with the rotary axes and associated with the sleeve code-fixing elements for contacting with the code Vym elements cams - in the walls of the housing and the sleeve respectively formed coaxially -skvoznye blind holes and slots for retaining the cam elements, the latter are in the form of pins mounted for axial re-h on ate ate

Code Navba Bezduzhkovy lock

, " BUT

It contains a hollow body 1 s (a hollow bottom, a sleeve mounted in the body rotatably 90 °, which is determined by a groove 3, in the body and a protrusion 4 on the sleeve which also has a blind central slot 5 for lockable eyelets of the hinges (on the Drawings shown), a bolt, made in the form of balls 6, which are located in holes 7 coaxial with each other on both sides of the central socket, rotary axes 8, evenly spaced around the circumference of the lock case with code cams 9 fixed on them, made in the form of eccentric disks, the pushers 10 are spring-loaded from the center of the lock by flat springs 11, while the pushers 10 are located perpendicular to the axis 8 and interact each with one end with the cams 9, and the opposite with the grooves 12 made in the sleeve 2, in the case there are radius grooves 13, the case below closed with a lid 14.

Code lock works as follows.

To open the locked lock, you need to dial the lock code on the rotary axles, while the eccentric code cams 9 rotate with their minimum lengths to the pushers 10 and the springs 11 push the last of the slots 12, thereby breaking the connection of the sleeve 2 with the housing 1, after which case 1 is turned counterclockwise by 90 ° due to the movement of the protrusion 4 in the groove 3 and the lock is locked to itself - it comes off the ears of the hinges of the locked door, since the balls 6 under

 by the action of the eyelets of the hinges of the door, they go into the grooves 13,

Locking the lock. The lock with the dial in the open code position is put on

the eyelets of the hinge of the lockable door, which, entering the slot 5, push the balls into recesses 13. Then the lock case 1 is turned clockwise, while the balls 6 are pushed out of the recesses 13 and locked

ears of door hinges. By turning the axles 8 by arbitrary sizes, they knock down the lock code, while the eccentric cams 9 overcome the resistance of the springs 11 and push the pushers 10 into the grooves 12 on the hub 2,

thus, it becomes impossible to open the lock without knowing its code.

The proposed lock is convenient to use, since all operations for opening-locking can be performed

with one hand and it is not necessary to take the parts of the lock out of its body, no additional items are required for opening.
