Abstract
A timing gear arrangement, an idler gear arrangement and a code gear arrangement are mounted in parallel with each other such that the timing gears are in mesh with the idler gears which are in mesh with the code gears. Push buttons are associated with each of the idler gears on the idler gear arrangement, and each push button is connected to a slider plate which will cause its associated code gear to rotate a predetermined distance when the push button is depressed. Further, the code gear arrangement is removably mounted in the lock control assembly.
Claims11
A permutation type lock control assembly, comprising;
- a timing gear arrangement comprising a plurality of timing gears mounted on a timing gear shaft for rotation with said timing gear shaft;
- an idler gear arrangement comprising a plurality of idler gears, equal to said plurality of timing gears, mounted on an idler gear shaft for rotation about said idler gear shaft, each of said idler gears being aligned with a respective one of said timing gears;
- a code gear arrangement comprising a plurality of code gears, equal to said plurality of timing gears, mounted on a code gear shaft for rotation about said code gear shaft, each of said code gears being alignable with a respective one of said idler gears;
- a plurality of push buttons, equal to the plurality of timing gears, each of said push buttons being associated with a respective one of said idler gears;
- means connecting each of said push buttons to their associated code gears to rotate the code gears a predetermined distance when the associated push button is depressed, each said code gear being rotatable by a motion substantially perpendicular to the motion of its associated push button when its associated push button is depressed.
A permutation type lock control assembly, comprising;
- a timing gear arrangement comprising a plurality of timing gears mounted on a timing gear shaft for rotation with said timing gear shaft;
- an idler gear arrangement comprising a plurality of idler gears, equal to said plurality of timing gears, mounted on an idler gear shaft for rotation about said idler gear shaft, each of said idler gears being aligned with a respective one of said timing gears;
- a code gear arrangement comprising a plurality of code gears, equal to said plurality of timing gears, mounted on a code gear shaft for rotation about said code gear shaft, each of said code gears being aligned with a respective one of said idler gears;
- a plurality of push buttons, equal to the plurality of timing gears, each of said push buttons being associated with a respective one of said idler gears;
- said code gear arrangement being removably mounted in said lock control assembly.
