LOCKING SYSTEM (VARIANTS) Russian patent published in 2005 - IPC

Abstract RU 2246600 C2

FIELD: access prevention systems.

SUBSTANCE: first variant of locking system has block 1 for receiving code, switchboards 2₁,…,2₃ for unblocking, locks 3₁,…,3₄, working devices 4₁…,4₄. First input of each switchboard 2₁,…,2₃ for unblocking is connected to input of first lock 3₁ and output of code-receiving block 1, one of outputs of locks 3₁,…,3₃ is connected to second input of appropriate switchboard 2₁,…,2₃ for unblocking, output of which is connected to input of following lock 3₂,…,3₄, output of each lock 3₁,…,3₄ is connected to input of executive device 4₁,…,4₄. Second variant of locking system has block 1 for receiving code, switchboards 2₁,…,2₃ for unblocking, locks 3₁,…,3₄, working devices 4₁,…,4₄, switchboards 5₁,…,5₃ for blocking. First input of switchboard 5₁,…,5₃ for blocking is connected to output of code-receiving block 1 and first input of unblocking switchboard 2₃, first input of switchboard 2₁,…,2₂ for unblocking is connected to output of following switchboard 5₂,…,5₃ for unblocking, first output of lock 3₁,…,3₃ is connected to second input of respective switchboard 2₁,…,2₃ for unblocking, output of which is connected to input of following lock 3₂,…,3₄, second output of which is connected to second input of previous switchboard 5₁,…,5₃ for blocking, output of switchboard 5₁for blocking is connected to input of lock 3₁, output of lock 3₁,…,3₄ is connected to input of working device 4₁,…,4₄.

EFFECT: higher efficiency.
