Abstract
A handle operating mechanism that may be lockable includes a housing that defines a forwardly facing recess for receiving a handle that is movable from a nested non-operated position to an extended operated position. A connection plate located behind the housing is pivotally supported by the housing for limited angular movement from a non-operated orientation to an operated orientation in response to movement of the handle from the non-operated position to the operated position. The connection plate is provided with a plurality of connection formations arrayed in a novel way about the pivot axis of the connection plate to ensure that pairs of lengthy, oppositely directed links coupled to the connection formations move concurrently and substantially equidistantly to operate various arrangements of remotely located latches including pairs of latches situated on opposite sides of the handle operating mechanism. A linkage that drivingly connects the handle to the connection plate may include a lock operated disconnect for preventing the handle from pivoting the connection plate when locked.
