Abstract: The present invention discloses a coin operated device, whereby the articles inside the locker can still be taken out with the spare key of the locker provider without damaging the coin operated device when the key is lost. The coin operated device is installed in the door frame of a locker and comprises first and second lock cylinders respectively for the insertion of the spare key and the key. The second lock cylinder is used to lock or unlock the locker, wherein a coin is inserted into the coin operated device, and a coin triggered module lets the coin fall into a coin accommodation module; then, the key is turned to latch the lock tongue and lock the locker, and the coin accommodation module is simultaneously driven to let the coin stay in behind the coin return.

Abstract: A coin-operated locking device includes a locking unit, a retaining unit, a driving unit, a coin-actuated unit, a user input unit, and an actuating unit. The locking unit is movable between locking and unlocking positions. The retaining unit is movable between a retaining position, where the retaining unit prevents movement of the locking unit between the locking and unlocking positions, and a non-retaining position, where the retaining unit permits movement of the locking unit between the locking and unlocking positions. The driving unit drives movement of the retaining unit between the retaining and non-retaining positions when actuated. The actuating unit actuates the driving unit upon receipt of the coin-deposited signal from the coin-actuated unit and a user input signal from the user input unit.

Abstract: A lock assembly includes a plurality of lock devices and a locking chain. Each lock device includes: a lock housing unit including upper and lower lock housings respectively formed with a rod hole and a jaw hole; a jaw actuating unit including a jaw actuator operable to move between locking and unlocking positions, and an urging member for urging the jaw actuator to the locking position, the jaw actuator having a ring portion and an operating rod extending through the rod hole; and a jaw unit including two locking jaws each having a hooking section that extends out of the jaw hole and an opposite force bearing section, and two biasing members for biasing the force bearing sections toward each other. The locking chain is extended removably through the positioning rings and the ring portion of each of the lock devices.

Abstract: A security lock includes a housing, a pair of intersecting and pivotally interconnected locking arms that respectively have hooks extending outwardly of the housing and heads extending into the housing; and a key-operated lock disposed inside the housing and has a lock shell, and a rotatable core. The core has a tail projecting therefrom to extend between the heads, and includes two opposite first sides and two opposite second sides. A cross-section of the tail that is transverse to the first and second sides has a long distance between the first sides, and a short distance between the second sides. The hooks may be changed in position to engage or disengage a slot formed in an article by merely turning the core using a key.

Abstract: A computer lock includes a housing having a groove opening at an outer surface thereof to receive an end of a fastening cable and/or a part of a computer. An actuator is disposed in the housing and actuated by a lock assembly disposed inside the housing so as to move toward the locking groove when the lock assembly is in a locking position. The actuator has a moving seat, a penetrating pin, and a push pin. The penetrating pin extends into the locking groove and engages the end of the fastening cable and/or the part of the computer received in the locking groove when the lock assembly is in the locking position. An anchor unit is disposed in the housing and controlled by the push pin to interlock with a hole of the computer.

Abstract: A computer security lock includes a main housing, a key-operated lock having a lock housing disposed in the main housing and having a lock bar extending movably through the lock housing, and a pair of scissors-type levers. Each lever has opposite proximal and distal end portions, and a medial part between the proximal and distal end portions. The distal end portion has a hook extending outwardly of the main housing to engage a slot in a computer housing. The medial parts of the levers are pivoted to the main housing at a common pivot point. The proximal end portions of the levers are biased to place the hooks in an unlatching position in which the hooks overlap. A cam is moved by the lock bar to extend toward and between the proximal end protions so that the hooks move away from each other. A cable holder extends around the main housing, and a security cable is connected pivotally to the cable holder.

Abstract: A combined clamp and lock includes: a lower clamp member having a lower abutment plate, a wall projecting upwardly from the lower abutment plate, and a lock-mounting hole extending through the wall; an upper clamp member having an upper abutment plate, and at least one leg extending downwardly from the upper abutment plate and overlapping the wall; a fastening unit fastening the leg to the wall so that the lower and upper abutment plates define a clamping space therebetween; and a lock extending through the lock-mounting hole. A notebook computer may be prevented from being opened when clamped within the clamping space and locked by the lock.

Abstract: A lock device includes a lock housing unit, a jaw actuating unit, and a jaw unit. The lock housing unit includes an upper lock housing formed with a rod hole, and a lower lock housing formed with a jaw hole. The jaw actuating unit includes a jaw actuator operable to move between locking and unlocking positions, and an urging member for urging the jaw actuator to the locking position. The jaw actuator has a ring portion disposed adjacent to a positioning ring of the upper lock housing, and an operating rod extending through the rod hole. The jaw unit includes an overlapping pair of locking jaws received in the lower lock housing and each having a hooking section that extends out of the jaw hole and an opposite force bearing section, and two biasing members for biasing the force bearing sections of the locking jaws toward each other.

Abstract: A master key includes a key base having a key handle, a fixing seat and a sleeve, all of which are connected to each other integrally. The fixing seat has a plurality of angularly spaced apart spring holes having respective key springs. A key tube includes a large cross-section tube section inserted into the sleeve, and a small cross-section tube section fixed to the fixing seat. The large tube section includes a plurality of angularly spaced apart long and short grooves. The long grooves are aligned with the respective spring holes to receive slide pieces, and the short grooves have respective shoulder faces. A tubular lock to be used with the master key is also disclosed.
