Key combination lock operates as follows.

If · the padlock, then the crossbar 3 closes or opens the handle of the padlock, if the door lock and so on. ' then the bolt 3 locks by connecting and entering the recess of the fixed part of the door. The exit of the bolt 3 is the closing of the door, the entry of the bolt 3 into the housing 1 of the lock is the opening of, for example, a door, a safe, etc. The key combination lock is encrypted. When the key 4 is inserted, when all the stops 12 are in the working guide grooves 14, the cipher is set up by inserting and turning the key 23, which displaces the forks 18 with its beards 22, and those disengage the digital disks 8 with the guide gears 13, Digital disks 8 rotate freely and set to the desired number, thereby re-encode before any locking, then remove the key 22 and, by turning the key 4, gear 11 is turned and the bolt leaves the housing '1, thereby closing the door, etc. The key 4 is removed, the springs 7 extend the upper 6, and the lower 5 lock latches, and the stops J 2 come out of the working guide grooves 14, then rotate the digital disks 8, while it is not visible which cipher was dialed before, and since the digital the disks 8 are meshed with the guide gear 13, then it rotates so that dummy guiding slots 15 are installed opposite the stops 12. If someone tries to open the lock in the absence of the owner, this fails, since the cipher can be locked every time change, not knowing the cipher If it is impossible to make a key mold, since the upper 6 and lower 5 locking latches do not match between the body 1 and the core 2 with their adjacent 5 ends when selecting keys or removing the impression, the stops 12 will not enter into the working guide grooves 14, but into the fictitious guide slots 15. A key code lock 10 opens as follows.

At the beginning, an encoded cipher is dialed, thereby the working guide grooves 14 are installed opposite the stops 12, a key 4 is inserted, 15 - which lifts the lower 5 with its barbs, and those upper 6 locking latches, the stops 12 go all the way into the working guide grooves 14, thus , the lower 5 locking 20 latches are installed in the core 2, and the upper 6 in the housing 1, thereby not interfering with the rotation of the core 2 and the entry of the crossbar 3.

A key combination lock is applicable 25 for any kind of locks, we do not open it to strangers without knowledge of the code, counterfeiting the key by taking a cast is not possible.

Claims (3)

This invention relates to key combination locks. A key lock is known, comprising a housing with a core mounted in it, spring-loaded twin locking pins coaxially located in the radial openings of the housing and core, and a key D 1. The well-known key lock cannot change the recording combination. The purpose of the invention is to increase secrecy. The goal is achieved by the fact that a key combination lock, comprising a housing with a core rotatable in it, spring-loaded paired locking pins coaxially located in the radial openings of the housing and the core, and a key, has a crossbar located in the housing, mounted on the core and contact with the bolt, spring-loaded digital disks, guide gears with working and fictitious grooves in contact with them, limiters rigidly connected to the record located in the grooves of the gears ayuschimi pins, and an additional key to change cipher mounted for contact with tsifrovmi disks. FIG. 1 shows a SSIMOK, a general sectional view; in fig. 2 - section 3 - section A-A in FIG. one; FIG. 4, view B on BB, FIG. 2; in FIG. 2. The lock has a case I with a core 2 rotatable in it, a bolt 3, a key 4, a bottom 5 and a top 6 locking pins, spring-loaded springs 7, digital discs B, spring-loaded springs 9, The bolt 3 has a tooth 10, which is permanently This engagement with the gear 1J of the core 2, and the upper locking pins 6 are rigidly connected to the stops 12, which cooperate with the guide gears 13, having a working guideway 13 and a fictitum, 1e directing grooves 15. The guide gears 13 has a tooth 16 that meshes with qi The rim disks 8 disks 8 have teeth J7, and the possible disengagement between them is carried out by forks 18 mounted on shaft 19 and spring-loaded springs 20, the forks have a wedge 21 interacting through barbs 22 with a key 23, the Key code lock works as follows in a way. If the lock is viscous, then the bolt 3 will close or open the handle of the padlock, if the door lock and i. Then bolt 3 locks, connects and enters the recess of the fixed part of the door. The exit of the transom 3 is the closing of the door, the entry of the transom 3 into the body 1 of the lock is the opening of, for example, a door, a safe, etc. The key code lock has a cipher configuration. When key 4 is inserted, when all the stops 12 are in the working guide grooves 14, the cipher is tuned by inserting and turning key 23, which with its beards 22 biases the forks 18, and the digital disks 8 are disengaged guiding gears J3, Digital disks 8 are freely rotated and set to the desired number, thereby recoded before any locking. Then the key 22 is taken out and by turning the key 4, the gear 1J is turned and the bolt exits the housing 1, thereby closing the door, etc. The key 4 is taken out, the springs 7 push the upper 6, and those lower 5 locking latches, and the stopper J 2 exit the operating guide slots 14. Then the digital disks 8 are rotated, but the cipher has been typed before, and As digital discs 8 are in engagement with guide gear 13, it also rotates so that, against J 2 stops, I install dummy guide slots 15. If, in the absence of a host, someone tries to open the lock, it is not succeeds, since the cipher can be changed every time it is locked, and not and if it is impossible to manufacture 5 of a key impression, since the upper 6 and lower 5 locking latches do not fit between case 1 and core 2 with their adjacent ends when selecting keys or taking an impression, limiters 12 will not enter working grooves 14, and into the dummy guide grooves J5. The key combination lock is opened as follows. At the beginning, the coded cipher is typed, thereby the working guide grooves 14 are installed opposite the stops J2, the key 4 is inserted, which with its beards lifts the lower 5, and those top 6 locking latches, the stops 12 go all the way into the working guide grooves 14, Thus, the lower 5 locking latches are installed in the core 2, and the upper 6 in the housing 1, thereby not interfering with the rotation of the core 2 and the deadbolt 3. The key code lock is applicable for any type of lock, cannot be opened by strangers without knowledge of the cipher, the key can not be falsified by taking an impression. Claim Code Lock, comprising a housing with a rotatable body in it, spring-loaded twin locking pins coaxially located in the radial openings of the housing and the core, and a key that is designed to increase secrecy in the housing bolt, gear gear mounted on the core and in contact with the bolt, spring-loaded digital disks, guide gears with working and dummy grooves in contact with them, located in the grooves of the gear n constraints, rigidly connected with locking brackets and an additional key for changing the cipher, installed with the possibility of contact with digital disks.
