A locking apparatus is provided that relates to a fastener and is used to solve a problem that time and labor are consumed and installation efficiency is low in a locking process of an existing locking apparatus. The locking apparatus is configured to lock a first module and a second module, and includes a locking body that is installed on the first module and a locking piece that is installed on the second module. The locking body includes a housing and a rotating block disposed inside the housing, where the rotating block is connected to a handle that drives the rotating block to rotate out of or into the housing, and the locking piece has a notch that accommodates the rotating block. The present invention is used to implement locking between modules.

A locking assembly for a door of a storage container is provided. The storage container defines a door frame, and the door is movably mounted to the door frame. The locking assembly may include a first keeper secured to the door frame, a first locking cam configured to movably engage the first keeper, and a handle assembly coupled to the first locking cam. The handle assembly may be movable between a first position in which the handle assembly is in contact with the door frame and the first locking cam engages the first keeper to maintain the door in the closed position relative to the door frame and a second position in which the first locking cam disengages the first keeper to allow the door to open. The first and second positions of the handle assembly illustratively define an obtuse angle therebetween.

A door latch activator system for a trailer or truck body coupled to a door latch, including: a plunger installed in a path of the door latch; a switch configurable into one of an open or closed position by the plunger; and a pneumatic valve configured to control flow of pressurized air through the pneumatic valve depending on the position of the switch, wherein the plunger is moved toward or away from the roller switch by the door latch operating in the path, which activates the pneumatic valve to control the pressurized air flowing through the pneumatic valve.

A lock lever structure includes a shaft; a cam attached to the shaft to fit a different-shaped portion of the shaft to prevent rotation of the cam in a circumferential direction of the shaft, the different-shaped portion having a different shape in cross section from a round portion of the shaft; a lever having an inner hollow cylindrical portion larger than an outline of the shaft and attached to the shaft to be rotatable in the circumferential direction of the shaft; a spring attached to the shaft to press the cam and the lever in an axial direction of the shaft; and a retainer attached to the shaft to retain the spring, the cam, and the lever to the shaft. The cam has at least two valley portions. The lever has a contact portion to contact the cam. The contact portion has a base shape.

A fenestration operation hardware assembly includes latch mechanisms configured for coupling to respective top and bottom sashes, and a paddle member configured for coupling the latch mechanisms. The latch mechanisms include movable latch bolts, and at least one of the latch mechanisms includes an operator interface feature movable between at least initial and operating positions. In an initial position, the latch bolts are in respective projected positions, and the top and bottom panels are immobilized. In a first withdrawn position, at least one of the top and bottom panels is movable, and in a second withdrawn position, at least one of the top and bottom panels is tiltable. In an example, a top latch bolt is moved by the paddle member according to movement of the bottom latch bolt.

A door latch activator system for a trailer or truck body coupled to a door latch, including: a plunger installed in a path of the door latch; a switch configurable into one of an open or closed position by the plunger; and a pneumatic valve configured to control flow of pressurized air through the pneumatic valve depending on the position of the switch, wherein the plunger is moved toward or away from the roller switch by the door latch operating in the path, which activates the pneumatic valve to control the pressurized air flowing through the pneumatic valve.

A fenestration operation hardware assembly includes at least one latch mechanism and an operation hardware assembly configured for coupling with a panel slidable within a frame. The latch mechanism includes a latch bolt and a latch biasing element coupled with the latch bolt. An operator of the operation hardware assembly is remote from the latch mechanism and is coupled with the panel. The operator includes an operator interface feature movable between initial and operating positions. In the initial position the latch bolt is in a projecting position, and in the operating position the operator interface feature moves the latch bolt into one or more withdrawn positions. The operation hardware assembly includes a retention assembly for retaining the latch bolt in a withdrawn position.

An operating mechanism is provided for an electrical enclosure. The operating mechanism includes a switch operator, and a housing to house the switch operator. The switch operator includes a portion which extends through one of one or more holes in the electrical enclosure, and can be manipulated by an external handle to operate an electrical switching device, such as a circuit breaker, that is housed in the electrical enclosure. The housing includes a cavity to house and protect an external antenna or other electrical device, which is connectable to an electrical cable that extends from the cavity into an interior of the electrical enclosure via the hole(s). The electrical cable can be connected to a monitoring system inside of the electrical enclosure. The housing is mountable onto an exterior surface of a wall of the electrical enclosure to cover the hole(s).

The disclosure relates to a closure device for attaching to a robot, preferably quick closure device and/or for overpressure-tight closing of a cavity of the robot up to at least 175, 200 or 225 mbar. The closure device comprises a removable covering element for covering a cavity of the robot and a fastening apparatus for fastening the covering element to the robot, wherein the fastening apparatus comprises a rotatable closure element. The fastening apparatus is characterized in particular in that it has a rotational closing movement between 45 and 215 and thus can be moved by a rotational closing movement between 45 and 215 into a closure position.
