A push and/or pull handle lockset, comprising: latch tongue (4) in first extended position, and operable to second retracted position; biasing means (6) urging the latch tongue (4) in first position; a linking means (12) to link the latch tongue to the actuator (16); sliding shaft (20) extending through lockset roses (27, 36), and operable from first position to second operating position; a biasing means (26) urging the sliding shaft to first position; an engagement means (21) for sliding shaft (20) to engage with actuator (16); lock accommodations (22, 30) for locking means; actuator (16) to translate movement of said sliding shaft to operate latch tongue (4) into second position; locking means (45) interposed between the lockset roses in parallel alignment with sliding shaft (20) including latch arm (46) which is rotatable in and out of lock sockets (22, 30); lockset unit operation is reversed by rotating the lockset unit one hundred and eighty degrees (180°) about it's horizontal lateral axis, changing the direction of actuator (16) or handle (43, 44) operation.

A latch mechanism includes a hook-handle assembly coupled to a first panel and a clevis coupled to a second panel. The hook-handle assembly engages the clevis to secure the first panel relative to the second panel.

A compression latch assembly for latching a panel to a frame includes a housing assembly, a lockplug assembly, a handle actuator assembly, and a rotating pawl assembly. The housing assembly defines an exterior well and a first and second compartment. The lockplug assembly resides within the first compartment and includes a lockplug having a circumferential guide surface. The handle actuator assembly has a handle within the exterior well, a crank coupled to the handle, and a drive shaft coupled to the crank. The handle and the crank rotate about common pivot point within the second compartment. The handle is selectively captured and ejected by interaction between the circumferential guide surface and a locking pin on the handle. The rotating pawl assembly has a hook defining a slot that receives the drive shaft. Pivotal movement of the handle actuates the hook by movement of the drive shaft within the slot.

A security reinforcement system for a door assembly having a door frame with first and second spaced-apart vertical structural supports and a door hinged thereto has first- and second-channel base plates respectively mountable to the first and second vertical structural support. Pivotally attached to the first and second base plates, respectively, are first and second opposed pluralities of security arms which rotate from a retracted position to an extended position in which security arms of the opposed pluralities extend toward each other across a portion of the door, reinforcing the door when first and second actuator arms operatively coupled to the first and second pluralities, respectively, are rotated from a vertical position to a horizontal position and are releasably coupled together by a sleeve.

A door-locking mechanism is for locking a door of a cabinet with respect to a main body of the cabinet. The door-locking mechanism includes a supporting component being operatively mountable onto the door, a driving component being operatively moveable with respect to the supporting component between at least first and second configurations, and at least one transmission component being operatively moveable with respect to the supporting component between drawn-in and drawn-out configurations. The door-locking mechanism also includes at least one locking rod being operatively connectable to the at least one transmission component and being movable between disengaged and engaged configurations with respect to a corresponding catch-rod of the cabinet, in response to the at least one transmission component being operated between the drawn-in and drawn-out configurations respectively, via an operation of the driving component from the first to the second configuration.

A cover for a handle of a cargo door to cover hasp elements and a lock. The cover includes a first housing with a first front wall, first side walls each having a front and rear edge, and a top end wall and define a first housing interior. A guide leg and a latch is disposed on the first housing. A second housing includes a second front wall, second side walls, and a bottom end wall that define a second housing interior. The second housing includes a guide socket configured to receive the guide leg and a catch configured to receive and retain the latch. The housing interiors define a cover interior that covers the hasp elements and an installed lock with one of the guide leg and the latch disposed behind the handle and the other of the guide leg and the latch disposed in front of the handle.

A handle for a compartment of a low, medium or high voltage switchgear includes: a body part; a hand grasping part; and a lock. The handle is movable from a closed position to an open position. When the handle is in the closed position, the handle is not useable to open a door of a compartment of the switchgear. When the handle is in the open position, the handle is useable to open the door of the compartment of the switchgear. In the open position, the hand grasping part is positioned so as to be graspable by a human user. In the closed position, a transition of an active element in the compartment of the switchgear from a quiescent state to an active or potentially active state activates the lock. Activation of the lock stops the handle from moving from the closed position to the open position.

This invention discloses a lock that set on a suitcase of being opened or closed without using a zipper, which including an operating component and a locking component that are separately-mounted; the operating component is set on a non-border position of the suitcase, and the locking component is set on the border of the suitcase, wherein the locking component comprises at least one locking unit, the force transfer between the operating component and the locking component is provided by a force transmission mechanism that connected between the operating component and the locking component; the operating component comprises an operation member, and the locking unit comprises a lock head and a lock hook, wherein driving the operation member can drive the lock head or the lock hook to move through the force transmission mechanism, to lock or unlock the lock. This invention also provides a suitcase provided with the lock as described above. This invention set the operating component and the locking component separately, which solves the problem that the lock can only be installed on the border of the suitcase, and only the locking component needs to be installed on the border of the suitcase, while the operating component can be installed at any position of the suitcase other than the border.

A structure of lock includes a core shaft, a swing arm, a push bar, and a keeper plate that are arranged in a lock. The swing arm is arranged at one side of the core shaft to selectively push or separate from a bolt. The push bar is arranged on an axle and has a top edge forming a notch. The keeper plate includes an elongate slide hole formed therein and an elongate positioning hole also formed therein and located below the slide hole. The slide hole is slidably fit over the axle and the positioning hole is slidably fit over a bar in such a way that the keeper plate is movable up and down along a curved path.

A security swing handle comprises a housing and a handle pivotally mounted to the housing between a closed position and an open position. A locking insert is rotatably supported in the housing and operatively connected to a latch to actuate the latch to release the handle to an open position. A hasp assembly includes a hasp at the bottom of the housing and a plate member disposed within an interior of the housing adjacent to a bottom of the latch. A pin on the locking insert is disposed within an aperture of the plate member to move the plate member against the latch to release the handle to the open position when the locking insert is rotated. If a padlock locked to the hasp is subjected to blunt force, edges of the aperture shear the pin from the locking insert disabling the locking insert.
