RU60113U1 - DOOR LOCK - Google Patents

Abstract

Usage: in the field of key hardware, and in particular in the castle, providing the necessary locking of rooms or objects. The essence of the utility model: the control cabinet contains a housing 1, inside which there are bolts 6 with reverse code slots and spring-loaded with pushers 7. The key 5 has a central rod 9 with a U-shaped element at the end, on the outer or outer and inner surfaces of parallel rods 9 of which made code ledges interacting with the corresponding grooves of the crossbars. 1 s.p. f-ly, 12 ill.

Description

The utility model relates to lock and hardware products for use in locks providing the necessary locking of rooms or objects.

Known overhead lock containing a housing and a lock plate, which is made with coaxial holes, a spring-loaded bolt with a group of code grooves, a latch position of the bolt, a keyhole and a key, on the rod of which a group of code ledges is made (see RU, patent No. 2054107, E 05 On 9/06, 1992)

The objective of the described utility model characterizing the overhead lock is to increase the reliability and secrecy of the lock and to exclude the possibility of opening it.

The specified technical result in the design of a padlock containing a housing and a lock plate with coaxial holes, a spring-loaded bolt with a group of code grooves, a bolt position lock, a keyhole and a key, on the core of which a group of code protrusions is made, is achieved by the fact that the key is made with П- a shaped element mounted on the end of the key rod, covering the latter with its parallel rods, and the code protrusions are made on the outer surfaces of these rods of the U-shaped element, in addition, codes The protrusions can be made on the inner surfaces of the parallel rods of the U-shaped element for interaction with the second group of code grooves, also made on the crossbar.

Figure 1 shows a lock in section; figure 2 is a section aa of figure 1; figure 3 is a section bB in figure 1; figure 4 is a section bb In figure 1; figure 5 - also without housing; Fig.6 is a section DD DD of Fig.5; Fig.7 -

on Fig - section FJ of Fig.7; in Fig.9 is a section ZZ of Fig.7; figure 10 - locking mechanism of the crossbars; figure 11 - lock on the door; in Fig.12 is a section GG of Fig.1.

The door lock includes a housing 1, which is secured to the base of the door 2 by means of a door trim 3 and a lock trim 4, which are a single part in which coaxial holes are made. The housing 1 and the lock plate 4 are made with coaxial key holes 5 and make up a single unit, assembled during installation by connecting with screws and bolts. In the housing 1 there are bolts 6 with reverse inclined code grooves, spring-loaded with pushers 7. The key 5 has a gripping ring 8, a central rod 9, at the end of which a U-shaped element 10 is fixed, covering the central rod 9 with its parallel rods. Groups of code protrusions can be performed on the outer surfaces of the rods 9, as well as on their inner surfaces, for interaction with the corresponding inclined code grooves of the bolts 6. In the claimed patch lock, the key-bolt clutch mechanisms are completely spaced relative to the inner hole of the keyhole, which eliminates damage mechanism. The area of operation of the key 5 is limited by a protective casing 11, mounted on the lock case. When installing the housing 1, the locking plate 12 is installed with the formation of the ledge. Each key-bolt clutch mechanism works only on its own code. The locks are provided with locks 13 of the crossbars, as well as a lockable stopper-clamp 14, which holds the clamps 13 in the non-worn state of the crossbars (the door is open) or in the closed state.

The described lock design provides reliable door closure, has increased secrecy and virtually eliminates unwanted opening of the lock.

Claims (2)

1. An overhead door lock comprising a housing and a lock plate made with coaxial holes, a spring-loaded bolt with a group of inclined code grooves, a bolt position lock, a keyhole and a key with one group of code ledges made on the rod, characterized in that the key is made with A U-shaped element mounted on the end of the key rod, covering the latter with its parallel rods, while the code protrusions are made on the outer surfaces of these rods of the U-shaped element. 2. The overhead door lock according to claim 1, characterized in that the code protrusions are made on the inner surfaces of the parallel rods of the U-shaped element, and the second group of code grooves for interacting with the code protrusions located on the inner surfaces of the said parallel rods is made on the crossbar.
