In a handle-returning device of a cylinder lock assembly, a support base has an inner annular flange and an axial spring-retaining lug. A rotation driver has an inner tubular wall extending into the inner annular flange of the support base, and a spring driving element. A torsion spring is disposed around the inner annular flange and between the support base and the rotation driver, and has a spring leg abutting the spring-retaining lug and the spring driving element. A rotary plate abuts the support base opposite to the rotation driver, and has an engaging part engaging a tongue projecting from the rotation driver. A reinforced structure is thus provided to oppose high torsional stresses produced upon rotation of a lever handle.

In a cylinder lock assembly, a latch operating tube has an enlarged end portion extending into an outer drive tube disposed in an outer handle. A locking spindle is disposed in the latch operating tube and has a locking tongue extending radially and outwardly through the outer drive tube to interlock with an outer rose when the locking spindle is pressed by a push button to move to a locked state. A locking plate is sleeved around the locking spindle and has a radial locking part to engage a protrusion that projects radially and inwardly from an inner surface of the enlarged end portion so that the locking spindle is locked against movements to an unlocked state when the locking spindle is in its locked state.

An electric door lock includes a transmission wheel driven by a motor and incorporating a spring with a driving end to drive a driven wheel. The transmission wheel and the driven wheel are rotatably sleeved around an inner drive tube connected to an inner handle. A spindle is inserted into the inner drive tube and has an operating end exposed from the inner handle. The driven wheel is connected integrally to the spindle for rotation. Preferably, a coupling piece extends through an arc-shaped slot in the inner drive tube and interconnects the driven wheel and the spindle.

A door lock includes a first driven wheel connected drivenly to a motor and having two resilient driving elements, and a second driven wheel connected drivenly to a rotary handle and the first driven wheel. The second driven wheel has a driven element disposed between and driven by the driving elements so that the second driven wheel moves to a first or second position to place a latch bolt in a latching or unlatching position. When the latch bolt is jammed, the second driven wheel is inoperative. However, as the driving elements are resilient, the first driven wheel can continue its rotation without being obstructed.

A door lock set including a cylinder lock unit which has a lock shell and a plug is disclosed. The lock shell has an axially extending protrusion which projects outwardly and radially from an outer periphery of the lock shell and which has a plurality of pin holes that receive respective springs and tumbler pins. A cover is disposed over the protrusion to cover the pin holes and is biased outward by the springs. The cover is compressible against the springs to reduce the size of the lock shell so that the lock shell can be inserted easily into a rear shank of a knob of the door lock set for assembly. In a preferred embodiment, the cover has two opposite lateral sides extending over and engaging movably two opposite lateral faces of the protrusion. Methods for assembling and disassembling the door lock set are also disclosed.

A lock with a support structure includes a tubular element connected to a handle having a positioning hole and a center hole. The center hole contains a lock set having a rotatable lock core connected to a transmission element. The transmission element has separated first and second sides. A transversally slidable element is installed to the tubular element for receiving a bias pressure of an elastic element, and includes a protruding portion and a bearing portion. The protruding portion can be moved between engaged and non-engaged positions of the positioning hole of the handle. The support structure includes a support portion. If the first side of the transmission element approaches the support portion of the support structure, the bearing portion of the transversally slidable element will approach the second side of the transmission element for limiting the displacement of the transversally slidable element when an external force is applied.
