Abstract:
1. An operating device for a lock, with the operating device comprising: a mounting plate including inner and outer faces spaced from each other along a first axis, with a window extending from the inner face through the outer face of the mounting plate along the first axis, with the mounting plate adapted to be mounted to an outer side of a door, with a receiving space extending from an inner side of the door through the outer side of the door and having an outer end covered by the mounting plate, with the window being aligned with and in communication with the receiving space; a frame adapted to be received in the receiving space of the door, with the frame including two first sidewalls spaced from each other along a second axis perpendicular to the first axis, with the frame further including a second sidewall extending between the two first sidewalls, with the second sidewall of the frame fixed to the inner face of the mounting plate, with the two first sidewalls including two aligned first holes and two aligned second holes, with each of the two aligned second holes spaced from one of the two aligned first holes along a third axis perpendicular to the first and second axes; a push member including a push section and a pivotal section spaced from the push section along the first axis, with the pivotal section including a pivot hole with the aligned with the two aligned first holes, with the pivotal section further including a sliding groove aligned with the two aligned second holes, with the sliding groove including first and second ends spaced from each other along the first axis, with an actuating pin mounted to the pivotal section and spaced from the sliding groove along the third axis, with the actuating pin intermediate the two first sidewalls of the frame, with a first pivot extending through the two first holes and the pivot hole, with a second pivot extending through the two second holes and the sliding groove and movable between the first and second ends of the sliding groove, with the push section extending out of the receiving space and adapted to be operably connected to a latch movable between an extended, locking position not allowing opening of the door and a retracted, unlocking position allowing opening of the door, with the push member pivotable between first and second positions about a first pivot axis defined by the first pivot, with the second pivot being in the first end of the sliding groove when the pushing member is in the first position, with the second pivot being in the second end of the sliding groove when the push member is in the second position; a lever including first and second ends spaced from each other along the first axis, with a lug formed on the second end of the lever and extending through the window into the receiving space of the door, with the lug including a first pin hole, with the second pivot extending through the first pin hole, allowing pivotal movement of the lever between an upper position and a lower position about a second axis defined by the second pivot, with the lever operably connected to the actuating pin, such that pivotal movement of the lever causes movement of the push member; wherein when the lever moves from the upper position to the lower position, the actuating pin drives the push member to pivot from the first position to the second position when the lever is pivoted from the upper position to the lower position, and the push section operates to move the latch from the extended, locking position to the retracted, unlocking position.
