Description

The invention relates to locking mechanisms and can be used as a lock to protect the premises.

Known shaft stopper with a locking mechanism to the patent of the Russian Federation №2324610 (publ. 05/20/2008). The shaft stop is equipped with a key for unlocking the secret mechanism and consists of a housing, a drum and a gripper. The housing and the drum are provided with pins located coaxially around the circumference along the axis with the formation of the locking mechanism. The drum is mounted in the housing with the possibility of rotation around its axis. The grip is rigidly mounted in the housing. In the grip and in the drum cutouts are made under the lockable shaft. A central cylindrical hole is made in the drum, into which a spring-loaded step piston is installed, which interacts with the pins of the end and cylindrical parts. Each pin consists of at least three parts. One part is stepped, interacting with a key, the other is a composite of a cylinder and a rod with the possibility of a fixed change in length, and the last is cylindrical, interacting with a piston. The last part of the pins is made stepwise, except for one pin, which is made cylindrical. The stepped pins are mounted with a smaller diameter in the drum and a larger one in the housing. In this case, a part of the stepped pin with a smaller diameter of the pins is located both in the housing and in the drum.

To open such a lock with master keys, as certification has shown, is extremely difficult or almost impossible. In most cases, the locking mechanism is jammed, and with a rough effect on the pins, it leads to complete blockage.

The disadvantage of this design is unstable operation - frequent jamming of the secret mechanism, the high complexity of manufacturing its parts, namely the piston and the rear stepped pins interacting with it. Even with high accuracy of their manufacture, as shown by the practice of operating the shaft stop, jamming of the locking mechanism or its complete blocking is possible. It is impossible to remove the secret mechanism from the wedge. The installation of such a stopper on a car in the form of an anti-theft device leads to extremely undesirable consequences and inconvenience, since unlocking the lock mechanism is possible only by cutting it.

The closest in the largest number of essential features is the castle mechanism to the patent of the Russian Federation No. 2549048 (published on 04/20/2015). The locking mechanism is equipped with a key for unlocking it and consists of a housing, a drum and a grip. The housing and the drum are provided with pins located coaxially around the circumference along the axis with the formation of the mechanism itself. The drum is installed in the housing with the possibility of rotation around its axis. The grip is rigidly mounted in the housing. In the grip and the drum, cutouts or protrusions are made under the locked part. Each pin consists of at least three parts. The last part of the pins is made integral - from a stepped shaft and a cylinder into which a stepped shaft enters. The length of the part of the stepped shaft included in the cylinder is less than the last. The last part of the pins is equipped with springs. Coaxial holes are made in the case and the drum of the lock - in the case of a greater length than in the drum. The holes in the housing are equipped with additional pins that interact with the drum during vibration. The length of the additional pins is equal to the length of the holes made in the housing. An increase in the reliability of the lock mechanism is achieved. Increases resistance to criminal hacking, vandal resistance and, most importantly today, resistance to vibration.

The disadvantages of this castle mechanism is the inability to install it on the door to protect the room.

The present invention solves the problem of expanding the possibility of using a reliable locking mechanism.

To achieve this technical result, in the door lock, equipped with a key for unlocking it and consisting of a housing, a drum, a gripper, a crown and spring-loaded pins installed in the housing and in the drum, constituting the secret lock mechanism, a radial hole is made in the drum and a pin is mounted rigidly connecting the drum and the crown, and in the grip there is a radial groove for the possibility of free rotation of the latter together with the housing around its axis when unlocking the secret lock mechanism, the crown is equipped with a threaded the lock for the lock in the door, in addition, the lock is equipped with a bolt, a bolt base, a thrust bearing, while the bolt base is mounted on a threaded sleeve with the possibility of free rotation on it, and the bolt itself is rigidly installed in the diametric groove made in the bolt base, in the bolt and in the grip are grooves that are interconnected with a spring-loaded button installed in the inner sleeve, and the latter is placed on the grip, which is threaded, and at the opposite end of the bolt there is a threaded hole in which installed glides.

Distinctive features of the proposed lock is that a radial hole is made in the drum and a pin is installed that rigidly connects the drum and the crown, and a radial groove is made in the grip to allow the latter to rotate freely together with the housing around its axis when the secret lock mechanism is unlocked, the crown is equipped with a threaded sleeve to secure the lock in the door, in addition, the lock is equipped with a bolt, a bolt base, a thrust bearing, while the bolt base is mounted on a threaded sleeve with the possibility of free rotation on it, and in the diametrical groove made at the base of the crossbar, the crossbar itself is rigidly installed, grooves are made in the crossbar and in the grip, which are interconnected with a spring-loaded button installed in the inner sleeve, and the latter is placed on the grip, which is threaded, and at the opposite end of the crossbar a threaded hole is made in which a thrust bearing is mounted.

The presence of significant features makes it easy to install the lock on the door leaf, making it only one hole under the crown. There is no need to make grooves and holes in the door jamb under the crossbars, which greatly simplifies the process of installing the lock.

The proposed door lock is illustrated by the drawings shown in FIG. 1-9.

In FIG. 1 - shows a front view (the lock is installed in the door leaf, the lock position is closed);

in FIG. 2 - key front view of the secret grooves;

in FIG. 3 - general view from above;

in FIG. 4 is a section Α-A of FIG. 3;

in FIG. 5 is a section BB of FIG. four;

in FIG. 6 is a front perspective isometric view (the lock is installed in the door leaf, the lock position is closed);

in FIG. 7 is a front isometric view (the lock is installed in the door leaf, the lock position is open);

in FIG. 8 is a front isometric view (the lock is installed in the door leaf, the lock position is closed);

in FIG. 9 is a front isometric view (the lock is installed in the door leaf, the lock position is open).

The door lock consists of a housing 1, a housing cover 2, a button 3, a spring of a button 4, a key 5, a drum 6, a grip 7, a crown 8, front pins 9, middle adjustable pins 10, rear pins 11, springs of the rear pins 12, all together making up the secret mechanism of the castle; as well as the threaded sleeve 13, the base of the crossbar 14, the crossbar 15, the pin of the drum 16, the inner sleeve 17, the spring button 18 and the thrust bearing 19. The door leaf is indicated by 20, the door jamb 21, and the lining on the door jamb 22.

A spring-loaded button 18 installed in the inner sleeve 17 connects the grip 7 and the crossbar 15 to transmit torque from the grip 7 to the crossbar 15. When the spring-loaded button 18 is pulled out of the inner sleeve 17, the connection between the grip 17 and the crossbar 15 is interrupted.

The door lock operates as follows. When installing the key 5 in the hole in the cover of the housing 2, made for him (Fig. 1, 4), the key 5 with its cutout (Fig. 2) enters the small diameter of the button 3 and sits on it. Then it is fed into the body of the housing 2 with the button 3 until it stops at the end of the housing 2. As a result of this movement, the key 5 interacts with its recesses with the end part of the front pins 9, moving the latter by certain code distances. The front pins 9 move the middle adjustable pins 10, and they respectively move the rear pins 11. As a result of these movements, when the key 5 is fully entered, the code for the middle adjustable pins 10 is set, they are installed in the contact plane of the housing 1 and the drum 6, and the secret mechanism is unlocked . After that, acting on the inserted key 5, the housing 1, rigidly connected with the cover of the housing 2 and with the claw 7, can rotate around its axis relative to the drum 6. With this action, button 3 is always pressed until the secret mechanism rotates 90 °. The rotation is carried out counterclockwise (Fig. 7).

When the housing 1 is rotated, the grip 7 is also rigidly connected with the latter, and through the spring-loaded button 18 acts on the crossbar 15, which rotates 90 ° together with the base of the crossbar 14, the inner sleeve 17 and the thrust bearing 19.

In this state, the lock is open, since the thrust bearing 19 of the bolt 15 does not affect the plate 21. The door 20 can be opened. After opening the door 20, the key 5 is removed from the cover of the housing 2. For this, the action on the button 3 is stopped, which is pushed out together with the key 5 under the action of the spring 4, and the key 5 is freely removed from the slot of the lock.

To lock the door, all actions are similar to those described above, except for turning the secret mechanism, which is performed in the opposite direction.

To close the door from the inside of the room, when the lock was opened from the outside, the following actions are performed:

- by hand we pull the spring-loaded button 18 from the inner sleeve 17 towards ourselves until it stops (the interconnection of the bolt 15 and the gripper 7 through the spring-loaded button 18 disappears) and turn the bolt 15 for the thrust bearing 19 from vertical to horizontal. The door is locked inside the room.

To unlock the door from the inside of the room, we perform the above steps in the same order, but we turn the bolt 90 degrees from horizontal to vertical. In this position, it is fixed by a spring-loaded button 18. The door is open from the inside of the room.

To close the door outside the room when it is open from the inside, we perform the following actions.

1. We leave the room and close the door until it stops.

2. Insert the key 5 into the hole of the housing cover 2, press the button 3 all the way and in the pressed position, turn the housing cover 2 with the key 5 clockwise until it stops in the cover plate 21.

3. We remove the key 5 from the lock, for which we release the button 3, which, under the influence of the spring 4, will slide out of the lock body and push out the key 5, which can be removed from the opening of the housing cover 2. When the key is removed, the secret mechanism will be fixed.

To open the door outside the room, which is closed from the inside, we perform the following actions:

1. Insert the key 5 into the hole in the cover of the housing 2, press the button 3 all the way and in the pressed position, turn the cover of the housing of the lock 2 with the key 5 clockwise until it stops. With this action, the bolt 15 is fixed with the spring-loaded button 18.

2. Without releasing the button 3, turn the lid of the housing 2 with the key 5 counterclockwise until it stops, moving the crossbar 15 in a vertical position.

3. Next, remove the key 5, open the door 20 and go into the room.

Such a lock easily adapts to existing protection - installed locks - and can be mounted next to them to significantly improve the quality of protection of the room.
