ELECTRIC-MECHANICAL LOCK Russian patent published in 2005 - IPC

FIELD: electronic control systems.

SUBSTANCE: device (fig. 1) has mechanism 1 for unblocking, standard code block 2, locking gear 3, working gear 4, comparator block 5, indicators 6₁…6_M, generator 7, pulse distributor 8, power enabling element 9, code input element 10, counters 11₁…11_M, counter starting value generation blocks 12₁…12_M, transforming block 13. transforming block 13 is made in form of cylinder, mounted on axis of kinematic connection between gear 1 for unblocking and locking gear 3 with possible effect on element 9 and element 10. first output of element 9 is connected to input of generator 7, output of which is connected to first input of each counter 11₁…11_M, group of outputs of block 2 is connected to group of inputs of block 5, output of which is connected to working gear 4, mounted with possible effect on said cylinder by blocking rotation of the latter around its axis, group of outputs of each counter 11₁…11_M is connected to group of inputs of appropriate indicator 6₁…6_M and to appropriate second groups of comparison inputs, input of distributor 8 is connected to output of element 10 and inputs of blocks 12₂…12_M, outputs of distributor 8, starting from first one, are connected to second input of respective counter 11₁…11_M, (M+1) output - to gating input of block 5, output group of each block 12₁…12_M is connected to input group of respective counter 11₁…11_M. on outer surface of cylinder 13 two recesses are made, wherein in starting state elements 9 and 10 are placed, second output of element 9 is connected to input of block 12₁. recesses dimensions are made in such a way, that in case of small turn of cylinder 13 element 9 would fall onto surface of cylinder 13 and enable power, and in case of even greater turn element 10 would fall onto surface of cylinder 13 and pick required code digit. Further rotation of cylinder 13 around its axis for unblocking locking gear 3 is limited by working gear 4. Length of recess should be appropriate for length of power enabling and code inputting elements in non-compressed state.

EFFECT: higher reliability.
