Abstract:
A door locking device of a distribution board of an air circuit breaker, including a transmission shaft transmitting power for drawing in and out a circuit breaker body, a shaft link rotatably coupled to one end of the transmission shaft, a link rod having one end rotatably coupled to a portion of the shaft link, a cam plate rotatably coupled to the other end of the link rod and pushing or pulling the circuit breaker boy, and a constraint plate installed in a distribution board door, further includes a pressing part protruding from a portion of the link road, and a hook plate rotatably coupled to a side of the cradle and having one end in contact with the pressing part to receive rotational force and the other end restricting or releasing the constraint plate, wherein the hook plate releases the constraint plate in a disconnection position.
Abstract:
An access panel for an opening in a duct is provided. The access panel includes an exterior and an interior. The access panel further includes a section positioned on the interior and having a profile substantially corresponding to the opening in the duct. A plurality of fasteners is positioned about the section. Each fastener has a dip configured to move to a position defined to extend away from the profile of the section on the interior. When the access panel is positioned with the section on the interior against the opening in the duct and the fasteners are moved to the locking position the clips rotate to extend over the profile and secure a portion of the duct adjacent to the opening against the interior of the access panel.
Abstract:
A device may limit opening of a sash hingedly coupled to a master frame, and includes: a bracket attached to the sash; a first arm having a first end pivotally coupled to the bracket; a second arm having a first end pivotally coupled to the first arm's second end; means for biasing the second arm into a retracted position; and a release assembly. The release assembly is secured to the master frame and includes a hook pivotable between a first position and a second position, which, in the first position, may be releasably received in an opening in the second end of the second arm when the second arm is in the retracted position, as the sash is closed and received within the master window frame The second arm is disengaged from the hook, permitting fill opening of the sash, when the hook is pivoted into the second position.
Abstract:
The invention relates to a lock (1) which can be actively released and locked by control technology, particularly for use in automatic storage machines having a plurality of compartments with compartment doors (2) which are to be opened individually, and to an automatic storage machine having at least one such lock (1). The lock (1) comprises a detent pawl (14), which can lock a locking element (9), which is permanently connected to a compartment door (2), in the lock such that the compartment door (2) can be held in closed position. The lock further has a first electric drive element (17) which transitions the detent pawl (14) from the locking position to a release position upon the applying of electrical power, such that the compartment door (2) can be opened. The lock (1) further comprises a security device (32), which prevents an automatic reset of the detent pawl (14) from the release position to the locking position when the lock (1) is in an unpowered state or the automatic storage machine is in an unpowered state, and an unintentional, accidental or improper locking of a compartment door can thus be avoided. In order to properly lock a compartment door, the security device (32) of the lock (1) comprises a second electric drive element, by means of which the detent pawl (14) can be transitioned back to the locking position thereof upon the applying of electrical power to said second electric drive element during closing of the compartment door (2).

Abstract:
An enclosure and enclosure locking system for an enclosure having an opening with a door or access panel utilizes first and second side mounting brackets that are each coupled to opposite portions of the enclosure. First and second locking strap members overlie the door or access panel when the door or access panel is in the closed position when in a locked condition. A staple assembly is used for receiving a shackle or lock pin of a pad lock and also for coupling the strap members together and locking the locking system 30 in a locked condition.
Abstract:
A locking device for a container having a hinged lid, comprises a base unit adapted to be fixed to the container and a pivotable unit mounted to the base unit and pivotally movable between open and closed positions. The base unit includes a locking mechanism comprising a casing, a rotatable shaft, a blocking member fixed to the shaft and disposed in the casing, and a rolling member. The pivotable unit is mounted to the shaft of the base unit. The rolling member is provided to move within the casing between a blocking position wherein the rolling member blocks movement of the pivotable unit relative to the casing to prevent unauthorized opening of the lid, and a release position wherein the rolling member moves away from the blocking member to permit the movement of the blocking member relative to the casing thereby permitting opening of the lid.
Abstract:
The disclosure is directed to motorized closure assembly, comprising: an opening frame configured to fit around the opening; a substantially rectangular closure slab having a closure slab frame configured to surround the substantially rectangular closure slab and sealingly fit within the opening frame; and a motorized driver, wherein the motorized driver is entirely embedded within the closure slab frame or within a combination of the closure slab frame and the opening frame, the motorized driver con figured to slidably move the slab between an open position and a closed position.
