Abstract:
The locking container is a selectively lockable container for the storage of used cooking oil and the like. The locking container includes a reservoir and both front and side locking mechanisms. The front and side locking mechanisms selectively retain a screen within the reservoir. The container is adapted for the disposal of oils, solvents, acids and various other liquid wastes. The pair of locking mechanisms allow access for storing the liquid waste in the container, but prevent unauthorized removal of the liquid waste. The container includes a lid to cover the screen, with the lid being secured by the front locking mechanism. The side locking mechanism locks the screen to the reservoir.
Abstract:
A padlock comprises a lock body, a shackle, a block member, an elastic member, a combination locking device and a key locking device. The shackle is movable relative to the lock body between a locked position and an unlocked position, and the shackle has a first end movably installed in the lock body and a second end. The block member is movably connected to the lock body and comprises a button provided for retaining the second end of the shackle in the locked position, a supporter protruding from the button, and a base protruding from the supporter. The elastic member is installed around the button and has one end against the lock body and the other end against the supporter. The combination locking device is installed within the lock body for controlling movements of the shackle. The first end of the shackle is movable to the unlocked position when the combination locking device is unlocked. The key locking device is installed within the lock body and connected to the base of the block member for controlling movements of the shackle. The block member is movable axially, when the key locking device is operated by a key.

Abstract:
A remote-controlled burglary preventing door lock includes a motor to be started by a remote controller to rotate reversely and drive a cam disk to rotate counterclockwise and actuate the upper end of a blocking pin to move downward and disengage from the stop rod at the inner end of a deadbolt, letting the deadbolt no longer blocked by the blocking pin. Thus, the door lock can be unlocked. To lock the door lock, the motor is started by a remote controller to rotate clockwise and drive the cam disk to rotate clockwise and actuate the upper end of the blocking pin to move upward and block the rear side of the stop rod at the inner end of the deadbolt, letting the deadbolt blocked by the blocking pin and impossible to retract toward the interior of a lock shell, having an excellent effect of burglary prevention.
Abstract:
A locking device, which mounts a user key (the first key) and a manager key (the second key) separatedly, places a first lock and a second lock unitedly in an outer cylinder. The first lock is opened or rotated by the first key. After the first lock is open, the first key cannot be pulled out of the locking device. If the second lock is open by the second key, the first key can be pulled out together with the second key.
Abstract:
An electronic lock box contains a secure compartment for storing keys to a structure. A linear actuator moves in one direction opening the door to the secure compartment, and moves in the opposite direction releasing a shackle that holds the lock box to the structure. A lock box system uses an encryption algorithm to diversify user PIN data at a central computer, and stores that diversified information on a memory card for later use when the user attempts to access a lock box. The central computer and electronic lock box both keep track of system “epoch time,” and the memory card must be presented to the electronic lock box within a correct epoch time window for the diversified PIN data to be successfully decrypted and compared to the user's PIN data that is entered on a keypad of the electronic lock box.
Abstract:
The invention relates to a safe mechanism for resistance to drilling, by use of a door mounted crankshaft mechanism. The crankshaft includes a shoulder which transfers force to the safe door rather than transmitting it to other lock mechanism components. A crank plate attached to the crankshaft rotates from an open position to a locking position, and by rotation moves a link arm with attached locking pins laterally into engagement with the doorframe. A re-locker device locks both the crank plate and the link arm in place to make entry more difficult.
Abstract:
A lock-picking prevention apparatus is adaptable to a lock (120) having a lock hole (121) and an abutment driver pin (122) for restricting and releasing a key. The apparatus includes a locking body (102) having a front end abutment hook (102d) abutted by the abutment driver pin (122) when the lock-picking prevention apparatus is inserted into the lock hole (121) so as to bury its internal space, an operating bar (102) provided so as to slide over the abutment driver pin (122) to provide guidance, and a new key (110). At the time of unlocking using the new key (110), the operating bar (103) pushes in the abutment driver pin (122) to release the abutment of the front end abutment hook (102d) so as to enable the locking body (102) to be pulled out. The lock-picking prevention apparatus brings about a situation which is equivalent to a plurality of locks being provided.
Abstract:
Although a door locking handle assembly is small as a whole in thickness, it permits through a computerized personal management system of users a plurality of persons or users to have access to instruments contained in a box provided with the door locking handle assembly in an easy manner. In the assembly, a combination lock (19) opened by turning each of a set of its specially marked dial discs (21) a given number of times to establish a unique combination of marks of the dial discs (21) is incorporated in a door handle (13) or a base body (1) of the assembly. In operation, a locking member (44) of the assembly prevents the door handle (13) from being pulled out of the base body (1), and is driven to reach its unlocked position when the combination lock (19) is opened.
Abstract:
A plate pivotally mounted to a padlock hasp adjacent a reciprocally movable operator handle is pivotable from a stored position to one covering the opening of the hasp, the plate having a hole aligned with the opening and smaller than the opening to receive the shackle of a single, scissors-type safety lockout and maintain the shackle in position to block movement of the operator handle to an operated position. The hole is preferably rectangular to conform to the flat, thin shape of the safety lockout shackle to maintain the shackle properly oriented. An additional round hole for a smaller diameter padlock shackle may be provided in said plate.
