Description

The invention relates to locks and bolts and can be used to protect critical facilities with the automatic issuance of an electrical signal for both successful and failed opening of the locking device.

A known method of controlling an attempt to enter a room, the door of which is closed to a locking device including a housing, a code mechanism and a plate fastened to a signal rod, which means that the plate is fastened to a code mechanism, and the signal rod is brought out of the housing and upon successful opening or closing of the locking device, as well as upon unsuccessful opening or closing of the locking device, the signal rod is moved, characterized in that when the opening is not successful, of the locking device, the signal rod is moved around its longitudinal axis, and if the locking device is successfully opened or closed, the signal rod is moved in a straight line in the corresponding direction (see decision of March 20, 2007 on the grant of a patent for an invention according to application No. 2005138419/12 (042882 ), paragraph 6 of the claims).

A locking device (sliding deadbolt) is also known, comprising a housing which is made in the form of a plate with bent side edges forming guide grooves in which the movable plate is placed, while in the housing there is a longitudinal slit passing into the first hole opposite which in the movable plate the second hole is made and a code disk with a plate is inserted in it, which is included in the first hole of the housing with the possibility of rotation of the code disk with the plate, and also with the possibility of longitudinal movement movably the plate when combining the code disk plate with the longitudinal slot of the housing, characterized in that the code disk plate is fastened with a signal rod that extends beyond the limits of the housing plate (see decision of 20.03.2007 on the same application No. 2005138419/12 (042882) , paragraph 3 of the claims).

The known method of controlling an attempt to enter a room, the door of which is closed to a locking device, as well as the known locking device (sliding bolt) are adopted as the closest analogues.

The invention is directed to the guaranteed issuance of informational electric signals both with a successful and with a failed opening of the locking device with the possibility of subsequent analysis of the issued signals.

In a method for monitoring an attempt to enter a room, the door of which is closed to a locking device including a housing, a code mechanism and a signal rod in contact with it, namely, when an attempt is made to decode a code mechanism, the signal rod is moved, the essence of the invention is that after the start of the movement of the signal rod, an electric signal is issued, and the issuance of the electric signal is stopped after decoding the code mechanism, while the success or failure of rushing into a room is judged by the totality of the duration of the electrical signals or (and) the gaps between them.

In a locking device comprising a housing, a code mechanism and a signal rod in contact with it, the invention consists in the fact that the code mechanism includes a first cylinder located in the housing, coaxial holes are made in the housing and in the first cylinder, in the housing openings and the first cylinder placed spring-loaded locking pins, and in the holes of the first cylinder there are pushers with the possibility of contact with the spring-loaded locking pins and the key with protrusions, and the signal rod it is made in the form of a second cylinder, which is located inside the first cylinder and the ends of the pushers abut against the surface, while the channel for the key is made in the second cylinder, when the key is inserted into it, its protrusions extend beyond the surface of the second cylinder with the possibility of stopping the protrusions of the key at the ends of the corresponding pushers when turning the second cylinder with a key at a certain angle while the first cylinder is stationary, a cavity is made in the first cylinder in which the ends of the pushers are placed with the possibility of placement in this cavity and protrusions of the key, while the end of the second cylinder extends beyond the housing and a permanent magnet is fastened to the end of the second cylinder, and a reed switch is fixed on the outside of the housing with the possibility of its operation when the second cylinder is rotated.

Figure 1 shows a locking device, the analogue of which is a cylinder lock mechanism according to the patent of the Russian Federation No. 2222676, EV 27/00, front view.

Figure 2 is a section along aa of figure 1.

Figure 3 is a section along BB-2 of figure 2 with a key inserted into the second cylinder.

The drawings indicate: a locking device (cylinder lock mechanism), comprising a housing 1, inside which a first cylinder 2 is placed. Inside the first cylinder, a second cylinder 6 with a channel 7 for a key is placed, while cylinder 6 acts as a signal rod, both cylinders 2 and 6 made and placed with the possibility of their separate and mutual rotation around the axis "O-O" and to prevent movement along the axis. The second cylinder 6, with its left end face, abuts against the first cylinder 2, and its right end end is provided with a flange 10. In the flange 10, a slot 11 is made, which coincides with the channel 7 and is intended to enter a flat key with protrusions into it. Along the generatrix of the first cylinder in the body and in the first cylinder there are made radial coaxial holes: the spring-loaded locking pins (delays) 3 are located in the holes of the body, which partially enter the holes of the cylinder 2 at different distances B. The pushers 5 are in contact with the delays 3, which their ends abut against the surface of the cylinder 6.

The pushers are L-shaped and consist of cylindrical proper pushers (pins) 5 and rectangular protrusions 8 attached to them at right angles, which are placed across the axis "O-O". The pins 5 and their ends 8 are deprived of the possibility of rotation around their axes by applying one of the possible known methods (not shown). A rod 4 is fastened to the left end face of the second cylinder 6, which is a continuation of the signal rod (second cylinder 6) and, through an opening in the housing 1, is brought out of the housing.

At the end of the rod 4 is fixed one of its ends made in the form of a bar permanent magnet 15.

The housing 1 is fastened to the door leaf 14 of the secured premises (as shown in FIG. 2) or completely recessed in the opening of the leaf 14, as one of the possible options in which a hole is made through which the signal rod 4, 6 is inserted into the inside of the secured room, which acts as a rotation lock for the signal rod.

A sealed magnetically controlled contact - a reed switch 16 is fastened to the protrusion of the sash 14, which is located on the circle described by the free end of the magnet 15 when it is rotated so that the reed switch 16 can be triggered when the signal rod 4, 6 is rotated.

To accommodate the protrusions 8 of the pushers 5, as well as the protrusions of the key and ensure their movements simultaneously with rotation by a certain angle of the cylinder 6 in the cylinder 2, a longitudinal cavity 9 is made, the dimensions of which allow the free rotation of the cylinder 6 by a certain angle and the movement of the pushers 5 with the cylinder 2 stationary .

Either cylinder 6, or cylinder 2, or a signal rod 4 attached to cylinder 6 can be used as the drive of the lock bolt, therefore, the diagram of the connection of one of them with the bolt is not shown in the drawings, since it (the circuit) depends on the particular design of the lock.

The key to the cylinder mechanism of the lock is made in the form of a plate 13 having a constant width, with protrusions 12 having different heights. The constant width of the key plate is equal to the height of the channel 7, that is, the diameter of the cylinder 6, so that the key inserted into the cylinder 6 with its protrusions 12 extends beyond the cylinder into the cavity 9, and after turning the cylinder 6 clockwise, the protrusions 12 of the key alternately (depending on the length of a particular protrusion) abut against the ends of the protrusions 8 of the respective pushers 5.

The proposed method for monitoring an attempt to enter a room, the door of which is closed to a locking device (lock), which includes a housing, a code mechanism and a signal rod in contact with it, includes the following operations:

1. The signal rod 6 is displayed outside the housing in the form of a rod 4.

2. The signal rod 6, 4 is fastened with a permanent magnet 15, which acts as a fixator for the angle of rotation of the signal rod.

3. A reed switch 16 is inserted into the composition of the locking device with normally open contacts, the input of which (to one of which) is supplied with electric voltage.

4. The signal rod is freely rotated by a certain angle around its longitudinal axis and during the rotation, by the action of the magnet 15, the contacts of the reed switch are closed and from its output (from the second contact) an electrical signal is output to the control panel for the operation of the locking device (not shown).

5. When you try to decode the code mechanism after the start of the movement of the signal rod, an electric signal is issued, and stops issuing an electric signal after decoding the code mechanism, while a successful or unsuccessful entry into the room is judged by the totality of the duration of the electrical signals or (and) the gaps between them.

In the initial presentation, the hovering device is closed: the spring-loaded locking pins 3 are inserted into the cylinder 2 at a distance B and inhibit its rotation, while the input of the reed switch 16 is energized, and its contacts are open, since the magnet 15 is located away from the reed switch.

To open the locking device, the key is inserted into the channel 7 and with it the second cylinder 6, the rod 4 and the permanent magnet 15 are rotated, while during the rotation when the magnet 15 passes over the reed switch 16, its contacts are closed and remain closed until the protrusions 12 of the key stop the protrusions 8 of the pushers and brake the cylinder 2, while the protrusions 12 of the key abut against the cylinder 2, during rotation of which the lock opens, while during the rotation of the cylinder 2 and the permanent magnet 15 the contacts of the reed switch 16 open. After the key is turned back, the lock is locked, the magnet 15 is set to its original position and the key is removed from channel 7, the locking device mechanism returns to its initial position, and when the magnet 15 is turned back after the pushers enter the cylinder 2, the reed switch 16 gives a secondary electrical signal, according to which You can judge the fact of closing the locking device.

Thus, when opening and locking the locking device with a standard key, the reed switch gives out two electrical signals of short duration, practically less than one second.

With a failed attempt to open the locking device, the protrusions 12 of the key abut against the protrusions 8 of the pushers and lift them up, but the cylinder 2 remains inhibited by the delays 3 placed in it, which leads to repeated attempts to brake the cylinder 2, which is characterized by the following symptoms:

- an increase in the number of sequentially issued signals,

- different time intervals between successively issued signals,

- different duration of individual signals.

The advantage of the proposed control method is that when it is used, it is possible to carry out double control by using a special control panel developed for this control:

a) for an attempt to illegally open the locking device (without breaking it) in order to steal the protected property;

b) for the normal operation of the locking device, since if there are several guarded premises, recording the facts of opening and closing the corresponding premises (with recording the opening and closing times) can help solve crimes related to the theft of various valuables by the staff serving or protecting these premises.

I consider it necessary to note that the proposed control method can be implemented in locks of any design with a high degree of awareness of the facts of illegal opening of the locking device by issuing an electrical alarm even before attempting to open the lock when turning the signal rod with any object, even with your hand. When using an autonomous power supply and transmitting a signal over the air, it is practically impossible to turn off the proposed alarm system.

Such locks are unknown to me and their introduction, I think, will be useful.

It would be nice even to patent this invention abroad, but for me, an ordinary pensioner, this is impossible.

I am ready to sell my invention, but for this I have no business connections and even no computer.
