RU56923U1 - LOCKING SYSTEM FOR OPENING-CLOSING DOORS OF DOOR BLOCK (OPTIONS) - Google Patents

Description

The locking system for closing-opening one or two doors of a door block is intended for use in the locking and locking technique for doors, and is also intended to protect the object from unauthorized entry into the room.

As you know, the door locking devices currently used are controlled outside the guarded room, i.e. access to mechanisms for putting them into action can be almost unhindered. When using modern types of locking devices for opening and closing doors, an outsider can observe and study how to open them, as a result of which attackers can only pick up a key or use a master key.

From the patent literature there is known a locking system for a door comprising a door frame and a door leaf, wherein a pad lock for opening and closing the door is located on the inside of the door leaf. (see FR 2572455, IPC E 06 B 5/11, 05/02/1986).

A disadvantage of the known locking system is its low protective characteristics, insufficient reliability against unauthorized persons entering the room due to the presence of only one easy-to-use padlock.

The technical result of the claimed utility model is to increase the reliability of closing the door and the security against unauthorized penetration of unauthorized persons into the premises, as well as the impracticability of using master keys.

The technical result of the claimed utility model is achieved due to the fact that the locking system for closing-opening the door, including a door frame, a door leaf, a through hatch made in that part of the monolithic wall that adjoins the opening-closing side of the door leaf, from the inside of which locking devices are made, one or more, for

closing-opening the door from the inside, and the entrance hole of the through hatch is blocked by a door having an internal lock for closing-opening the door of the through hatch or hatch and door at the same time.

The technical result of the claimed utility model is achieved by the fact that for the claimed locking system on the inner side of the door leaf a protective cover is made, and the locking device is mounted on top or bottom of the protective cover, and the locking device contains crossbars operating in a horizontal plane.

The technical result is achieved due to the fact that the locking system for closing-opening the door of the door unit includes a through hatch made in the door leaf, blocked by a door having an internal lock for closing-opening the door of the through hatch or hatch and door at the same time. On the inside of the door, locking devices are made, one or more, for closing and opening the door from the inside. The locking device is mounted on top or bottom of the protective casing and contains crossbars working in a horizontal plane.

The technical result is achieved due to the fact that the locking system for closing-opening two doors, an external and an internal door unit, includes a through hatch made in an external door, closed by a door having an internal lock for closing-opening a door of a through hatch or hatch, and doors at the same time. Locking devices are made on the inner side of the external door and contain crossbars, which, working vertically, engage with a plate rigidly connected to the inner door of the door block.

The technical result is achieved due to the fact that the locking system for closing-opening two doors, an external and an internal door unit, includes a through hatch made in an external door, closed by a door having an internal lock for closing-opening a door of a through hatch or hatch, and doors at the same time. Locking devices contain crossbars and are mounted on the inner door, and the outer door has a console. When locking the bolts through the console block the external and internal doors between each other.

It should be noted that when two doors are used in the door unit, there is an even greater possibility of increasing the system's inaccessibility due to the fact that the external and internal doors can be locked with each other by a locking device located in the inter-door space.

The essence of the utility model is illustrated by the drawings presented in the application:

1 embodiment of a locking system for closing-opening a door of a door unit.

The door unit comprises a door frame 1 and a door leaf 2. In the part of the monolithic wall 3, which is adjacent to the opening-closing side of the door leaf 2, there is a through hatch 4, the dimensions of which allow you to put your hand inside through the hatch and control locking devices 7, one or several. On the outside of the monolithic wall 3, which is adjacent to the opening-closing side of the door leaf 2, the inlet of the through hatch 4 is blocked by the door 5, for opening and closing of which serves the lock 6 (see Figure 1).

The door locking system according to 1 embodiment works as follows.

First, the door 5 of the through hatch 4, made in the monolithic wall 3, opens. Having put a hand into the through hatch 4, the owner "opens" or closes the locking devices 7 by touch.

2 embodiment of a locking system for closing-opening a door of a door unit.

The door unit comprises a door frame 1 and a door leaf 2. A door hatch 4 is made in the door leaf 2. On the outside of the door leaf 2, the inlet of the through hatch 4 is closed by door 5 with a lock 6 made therein to close-open the door 5 of the through hatch 4 or hatch and door at the same time. On the inner side of the door leaf 2 above and below it, or "randomly" is a system of locking devices 7 for closing and opening the door (see Figure 2).

For the above first and second embodiments of the locking system for closing and opening the door, it is also possible to execute a protective cover 8 from the inside of the door leaf 2 (see FIG. 3) so that the exit opening of the through hatch 4 is located inside the protective cover. The latter can act as a “trap” for the key (in case the locking devices 7 installed on the inside of the door leaf, made in the form of locks with masks), dropped out of the hands of a person, and as a protection of the room from unauthorized entry into the room of strangers , unwanted objects through the through hole.

In addition, for the above first and second embodiments of the locking system for closing and opening the door, it is also possible to arrange the locking device 7 on the inside of the door leaf from above and (or) similarly from below, the protective casing 8 so that the key is inserted into it from below , and (or) from above, and the crossbars of the locking device 7 work in the horizontal direction (see Figure 3, Figure 4).

3 embodiment of a locking system for closing-opening two doors of a door unit.

The door unit includes a door frame 1 and two doors - an internal 9 and an external 10. A through hatch is made in the outer door 10 4. On the outer side of the outer door 10, the inlet of the through hatch 4 is closed by door 5 with a lock 6 made therein for closing and opening the door 5 through hatch 4 or hatch and door at the same time. A plate 11 is rigidly attached to the inner door 9 with mating holes for the bolt of the locking device 7. The locking device 7, in turn, is mounted on the side wall of the protective casing 8. The bolts of the locking device 7 in the closed position through the plate 11 mounted on the internal door 9 are rigidly locked between the outer 10 and inner 9 doors, (see Figure 5, Figure 6)

For the specified 3 variants of the execution of the locking system for closing-opening two doors of the door block, it is possible to perform a locking device 7

in the following way. On the external door 10, the console 12 is either integral with the external door 10 or rigidly fixed to the external door 10 (for example, by welding or threaded connection, etc.). The console 12 has holes for the entry of the bolts of the locking device 7. The latter is mounted on the inner door 9 and is controlled through the through hatch 4. In the closed position, the bolts of the locking device 7 through the holes in the console 12 are fixed in the box 1 of the door block, rigidly blocking the external 10 and inner 9 doors.

The described embodiments of the locking system for closing and opening doors allow:

firstly: use the lock of the door of the through hatch both for closing-opening the door of the through hatch, and for short-term closing of the door, for example, turning the key by 1 revolution ensures closing the door of the through hatch and turning the key by 2 turns ensures closing the door for a short time without the participation of a system of locking devices;

secondly: locking devices located on the inner side of the door leaf or in the inter-door space can have various designs and can be controlled from the inside of the door leaf.

The apparent simplicity of the locking system is an effective way to protect against unauthorized opening of doors, since the locking devices are controlled from the inside of the door in a limited inter-door space and are hidden from the visual examination of the locking devices.

The locking system for opening and closing the door is designed in such a way that only the owner of the room knows the location of the locking device, and a random person cannot find the right locking device in a short time. To increase the efficiency and reliability of the locking system for opening and closing the door, connection to locking devices of signaling or blocking devices (so-called devices - traps) can be used. In addition, one of the advantages of the locking system according to option 1 is that the implementation of the through hatch in a monolithic wall prevents the use of a through hatch by intruders to attach devices for breaking or tearing the door leaf out of the door frame.

It should also be noted that another advantage of the locking system declared as a useful model for opening and closing a door is that the through hatch can be used to transfer small items (documents, mail, etc.) without opening the door to the owner of the room.

The advantage of the claimed system is the ability to use the space behind the inner side of the door leaf or the space between two doors. Locking devices can be oriented in different planes, which increases the stability of the locking devices from destruction.

It is also important to note that when blocking the external and internal doors between themselves, an attacker who entered the premises through the window will not be able to get out of the room through the door, since he will not be able to open the door from the inside.

The claimed utility model offers opportunities for improving existing locking devices, as well as designing new models of locking devices.

The claimed locking system can be widely used and used not only for residential premises (apartments, private houses), but also for garages, safes, etc.
