Abstract: A multiple function lock, which has dual, independently operated, locking mechanisms. In one embodiment, the multiple function lock is further comprised of a combination locking mechanism and a keyed locking mechanism. In one embodiment, the multiple function lock is further comprised of a gate mechanism for selectively securing and releasing a shackle of the lock.

Abstract: A padlock comprises: a casing; a shackle having a free first end and a second end, the second end being pivotally connected to the casing; a locking mechanism received within the casing and limiting the axial movement of the second end of the shackle; a latching tube received and operative to be moved within the casing; and a stop member driven by the latching tube so as to be moved between a first position where the first end of the shackle can be rotated by using the second end thereof as a center of rotation, and a second position where the stop member prevents the first end of the shackle from moving, and the shackle and the casing co-define a closed loop.

Abstract: The present invention relates to an electrical receptacle having a safety mechanism. The electrical receptacle includes a latch installed internally, where the latch is operated through a switch member positioned externally. The latch can be switched to a locking position or an unlocking position by the switch member. In the locking position, the plug is constrained to be unplugged or the plug is restricted to be inserted. In the unlocking position, the plug is free to be inserted or unplugged.

Abstract: A bonding lock comprises a body and a connecting member. An end of the connecting member joins to a fixed object, another end connecting to the body and constructing a loop for locking objects. The body has a slot with a slot opening, and the connecting member enters the slot via the slot opening for quickly completing buckling after a loop is formed by the connecting member and the body.

Abstract: A retractable wire lock includes cables or steel wires of different lengths to serve as connection members to couple with a first guarding member and a second guarding member, and a winding reel pivotally located in a casing to couple with and wind the connection members. The winding reel can adjust the length of the connection members according to actual requirements or fully wind the connection members for storing.

Abstract: A combination lock having a combination lock mechanism and a key lock mechanism. The combination lock mechanism is able to unlock and lock the combination lock by switching a plurality of dials exposed on the surface of the combination lock, while the key lock mechanism allows the user to unlock the combination lock with a key.

Abstract: A lock mechanism for latching a first object then coupling with a second object includes a case, a first shackle and a second shackle. The case includes a bolt assembly. The first shackle may be selectively coupled with the case to form a closed boundary with the case and latch the first object at a latch position, and unfasten the closed boundary at a release position. At the latch position, the first shackle is latched and anchored by the bolt assembly. The second shackle is movably mounted on the case and may latch the second object at a first position and release the second object at a second position.
