Abstract: Disclosed herein is a lock comprising a movably housed shackle stop, a shackle that is movably mounted and a shackle stop receiver for receiving the shackle stop to immobilise the shackle. The lock includes a shackle stop actuator is pivotable around a laterally orientated pivot axis and comprises a lateral cam surface configured to outwardly move the shackle stop into receipt by the shackle stop receiver. The lock includes a body configured to simultaneously receive a plurality of cylinder locks for actuation of the shackle stop actuator by any one of the plurality of cylinder locks.

Abstract: A latchbolt retractor (12) is described herein. The latchbolt retractor (12) comprises a latchbolt retraction mechanism (30) mounted to a carriage (28). The latchbolt retraction mechanism (30) comprising a latchbolt assembly coupler (32) for operational coupling to a latchbolt assembly (22). The carriage (28) is configured to slide along at least one rail (14,16) for positioning the latchbolt assembly coupler (32) relative to the latchbolt.

Abstract: Disclosed herein is a mechanism (30) for a lockset (10). The mechanism (30) comprises a latchbolt retractor (22) that is rotationally actuatable. The mechanism (30) comprises a rotationally mounted handle coupler (36). The rotationally mounted handle coupler (36) is rotatable by a rotation of a handle (12) when coupled thereto and comprises an adaptor receiver (46) for receiving any one of a plurality of adaptors (48,52,54). The rotationally mounted handle coupler is configured to engage with at least one of the plurality of adaptors (48,52), but not all of the plurality of adaptors (54), for transmission of the rotation of the handle (12) to a latchbolt retractor actuator (22).

Abstract: Disclosed herein is a mechanism (10) for transmitting a torque applied to a handle (12). The mechanism (10) comprises a torque transmitter (18). The torque transmitter (18) is for transmitting the torque applied to the handle (12) coupled thereto. The mechanism (10) comprises a torque transmitter stop (40) within the housing (14). The torque transmitter (18) and the torque transmitter stop (40) are cooperatively arranged for the torque transmitter stop (40) and the torque transmitter (18) to engage to arrest a torque transmitter rotation. The torque transmitter (18) and the torque transmitter stop (40) are cooperatively arranged for the torque transmitter stop (40) and the torque transmitter (18) to disengage when the torque so applied exceeds a predetermined torque value. Also disclosed herein is a method for operating the mechanism (10) for transmitting a torque applied to the handle (12).
