Abstract

FIELD: manufacture of locks. SUBSTANCE: according to the claimed method, lock is opened and closed by acting of control members through devices of code reception, sensing and fixing by actuator. In course of closing, lock combination degree is set up, and in lock opening with lock low combination, lock is acted upon by one control member. With combination degree set up by one control member, devices of code sensing and fixation engageable with other control member are interlocked, and with higher combination degree, devices of fixation engageable with both control members are mutually interlocked. During lock opening, with lock of higher combination degree, lock is acted upon by both control members by their location in two recesses. The first and second control members are used in form of keys, or the first control members are used in form of keys, or the first control member is used in form of key and releasing device operating during closing, and the second control member is used in form of key. Setting up of degree of lock combination and interlocking of devices of code sensing and fixation are effected from lock both sides. In setting of lock low degree of combination, device of code reception engageable with other control member is interlocked. In lock closing, high degree of its combination is set up by the first control member. EFFECT: improved conditions of lock use and higher degree of its combination with its negligible lowering in course of lock use. 3 dwg

Description

 The invention relates to mechanical engineering and can be used in the manufacture of locks.

 A known method of operation of a device for locking a door, including controlling the device for locking the door by dialing a code combination [1].

 The disadvantage of this method is the relatively easy access of the attacker to the code receiving device, made in the form of rings with numbers, which allows him to make attempts to open the lock without any devices, which increases the number of possible crimes. In addition, after each opening of the device, it is necessary to change the dialed code combination, since otherwise the door will not be locked, which causes inconvenience in operation. The operation is complicated by the fact that when using the device by several persons, a new code combination can only be established after its universal approval.

 The prototype is the method of operation of a mechanical lock, according to which the lock is opened and closed by acting on the actuator by means of control elements through a code receiving device, reading and fixing, in the process of closing the degree of security of the lock is set, and in the process of opening the lock with a lesser degree of secrecy, exposure to one element management [2].

 This method has the following disadvantages. The degree of security of the lock when it is exposed to it by the second control element (key) practically does not change, since the second key, in contrast to the first key, has one different protrusion interacting via a pin with an actuator. The remaining protrusions (teeth) of the second key fully (in shape and height) coincide with the protrusions of the first key. Given that the difference between the uneven protrusions of the keys is essentially predetermined by the design of the lock, then picking up the second key, having information about the first, is not difficult. The impact of both controls on the same code pins reduces the service life of the lock, and the establishment of a greater degree of secrecy with both keys reduces the ease of use of the lock. In addition, the availability of a key code receiving device makes it possible to perform a consistent selection of keys, which reduces the degree of security of the lock.

 The aim of the invention is to eliminate these disadvantages, namely, improving the operating conditions of the castle and increasing its degree of secrecy, including a slight decrease in the process of operation.

 This goal is achieved by the fact that in the method of operation of the mechanical lock, according to which the lock is opened and closed by acting on the actuator by means of control elements through the code receiving device, reading and fixing, the degree of security of the lock is established in the process of closing, and in the process of opening the lock to a lesser extent secrecy carry out the impact of one control element, when installed with one control element of a lesser degree of secrecy, code reading and fixing devices are blocked, interacting with another control element, and with a greater degree of secrecy, mutually lock the locking devices interacting with both control elements, while in the process of opening the lock with a greater degree of secrecy, they influence both control elements by placing them in two grooves. The keys are used as the first and second controls. Establishing the degree of secrecy and locking of code reading and fixing devices is carried out on both sides of the lock. When a lower degree of secrecy is established, a code receiving device that interacts with another control element is blocked. The key and the trigger device that is triggered when closing are used as the first control element, and the key is used as the second control element. In addition, in the process of closing the lock, a greater degree of secrecy of the lock is established by the first control element.

 The prior art does not reveal solutions that have signs that match the distinguishing features of the claimed invention and have the same effect as they, on the technical result, which consists in improving the operating conditions of the castle and increasing its degree of secrecy with a slight decrease during operation.

The invention is reflected in the operations:
- the establishment of at least one control element the degree of secrecy of the castle in the process of closing it;
- blocking, to a lesser degree, of code reading and fixing devices interacting with another control element;
- mutual blocking with a greater degree of locking devices interacting with both elements;
- opening the lock: to a lesser extent, the impact of one control, and with greater secrecy - both controls by placing them in two grooves.

 Moreover, the keys are used as the first and second controls. The degree of secrecy and the locking of code reading and locking devices are established on both sides of the lock. When a lower degree of secrecy is established, a code receiving device that interacts with another control element is blocked. The key and the trigger device that is triggered when closing are used as the first control element, and the key is used as the second control element.

 These operations allow you to achieve compared with the prototype of the following advantages.

 The establishment of a greater degree of secrecy by one control element allows, firstly, to improve the operating conditions of the castle (its consumer qualities) by reducing the time it takes to close it. Secondly, the devices for receiving the code, reading the code and fixing interacting with the key are not subjected to increased wear, which preserves a high degree of security of the lock during its operation.

 Blocking, with a lesser degree of secrecy, devices for receiving a code, reading a code, and locking devices interacting with another control element, completely eliminate the selection of keys (master keys) that can be used by attackers as a second control element.

 Mutual locking with a greater degree of secrecy of the locking devices interacting with both controls significantly increases the degree of security of the lock, since even if one of the keys is picked up by an attacker, a locked locking device will not allow him to rotate this key, and therefore, determine the correctness of the selected code (key). He will be able to do this only if he unlocks another locking device by selecting a second key, which complicates the selection procedure and unauthorized opening of the lock.

 Providing the possibility of installing different degrees of secrecy and blocking of code reading and fixing devices on both sides of the lock allows simplifying the procedure for opening the lock and on the other hand, for example, from the inside, with one key (handle) for a small degree, and two keys for a large one. An attacker who, for example, enters an apartment through a window and does not have a key, will not be able to open the lock from the inside with a handle if, when it was closed, the landlord established a high degree of secrecy. At the same time, the owner, being in the apartment and having established a lesser degree of secrecy when closing the lock, can open the door easily and quickly with the handle, if necessary, open the door.

 The execution of the first control in the form of a key and a trigger device, triggered when the lock (door) is closed, makes it possible to automatically set the desired degree of secrecy without using a key, which further improves operating conditions.

 The invention is illustrated by drawings, which shows a diagram of the mechanical lock: figure 1 - the location of the parts of the lock in the position when the lock is open; figure 2 - the location of the parts of the lock in the position when the lock is closed by turning the key one revolution; figure 3 - the location of the parts of the lock in the position when the lock is closed by turning the key two turns.

 The lock contains grooves 1, 2 for entering the key, in which the push pins 3, 4 are placed with the possibility of movement, interacting with the fixing pins 5, 6, which are pressed by the springs 7, 8. The groove 1 is made in the rotor 9, mounted for rotation in the stator 10 and rigidly connected to the gear wheel 11, which is engaged with the gear rack-bolt 12. In the bolt with axial movement, restrictive pins 13 are mounted, preloaded by the spring 14. The bolt is mounted to move along the guides 15 and 16 (with groove 2) and engagement with to yak 17 door.

 The method is implemented as follows.

 Insert the key into the groove 1 and turn it one turn. In this case, the gear 11 will partially move the crossbar 12 to the jamb 17, and the door will be locked. In this case, a lesser degree of security of the lock is established, and to open it, it is necessary to insert the key in the groove 1 and turn it one revolution in the opposite direction. It should be noted that when the bolt is partially moved, the pins 4 (code reader) and the pins 6 (fixation device) are blocked, and therefore the attacker does not have every opportunity to select the second key.

 To increase the degree of security of the lock, insert the key into the groove 1 and turn it two turns. The movement of the bolt along the guides 15 and 16 leads to the fact that the locking pins 6 are opposite the pressure pins 4, lifting the latter, partially go into the holes, fixing the bolt. The pins 6 and 5 (locking devices) turn out to be mutually locked through the bolt 12, so an attacker can only open the lock by simultaneously selecting the keys placed in grooves 1 and 2. If any one key is picked up, the lock will not change its state, but therefore, the attacker does not know: he picked up the key correctly or not.

 The opening of the lock begins with the placement of the second key in the groove 2, while the pins 6 and 4 occupy a position in which the line of contact coincides with the surface of the bolt 12, and it will be released in this place. Then insert the first key into the groove 1 and turn it in the opposite direction by two turns, and the bolt comes out due to engagement with the jamb 17. Then, remove the second key from the groove 2, and the lock returns to its original position.

 Thus, the complexity and duration of the castle control procedure are directly proportional to the degree of secrecy that the owner of the castle chooses at his discretion, which increases the operational properties of the castle. In addition, the automatic blocking of the most important components of the lock increases its reliability and significantly complicates the selection of keys for cybercriminals. The convenience of using the castle can be further enhanced. To do this, use a trigger device, with which the bolt moves when the door is closed without a key, while a lower degree of secrecy is automatically established. The establishment of a greater degree of secrecy in this case is carried out by turning the first key one revolution. Opening the lock in both cases is carried out by the described method.

 Choosing the right degree indoors also increases the convenience of using the lock, for example, in the daytime you can quickly open and close the lock by turning the key one turn, and at night, closing the lock by turning the key two turns, make it difficult to open it from the outside.

 The implementation of the invention will increase the reliability of the castle and its operational properties, which, ultimately, will improve its quality and consumer properties.
