The invention relates to a zipper device comprising a slider provided with a pull tab (113) having a locking eyelet at its end; a lock comprising locking means able to engage with the eyelet of the pull tab so as to secure and release said eyelet from the lock. The lock comprises a cover (220) that is movable between a closed position and an open position, capable of covering, in the closed position, the end of the pull tab secured to the lock, and of uncovering this end in the open position, the cover being locked in the closed position when the pull tabs are locked in the lock. The invention also relates to a piece of luggage provided with such a zipper device.

The lockset of the present disclosure includes a housing, a lock body, a first A clamping hook and a second A clamping hook. The housing includes a housing top surface, and the housing top surface includes a lock body embedding opening, and a first A insertion hole and a second A insertion hole which are located in two opposite sides of the lock body embedding opening. The lock body is disposed in the housing and includes a lock body top surface. The first A clamping hook corresponds to the first A insertion hole, and is capable of selectively rotating to open or close the first A insertion hole. The second A clamping hook corresponds to the second A insertion hole, and is capable of selectively rotating to open or close the second A insertion hole. When the lockset is in an unlocked state, the lock body top surface is capable of being pushed by an external force at a position adjacent to the first A insertion hole to generate a downward displacement, so that the first A clamping hook is rotated to enable the first A insertion hole to be open; and the lock body top surface is capable of being pushed by an external force at a position adjacent to the second A insertion hole to generate a downward displacement, so that the second A clamping hook is rotated to enable the second A insertion hole to be open.

A magnetic buckle device has a first base, a major inserting head, a second major base, two major components, and a controlling assembly. The major inserting head can be inserted into the first base to engage and lock. The second major base and the first base can be moved or rotated with respect to each other such that the major inserting head enters a disengaging state. The two major components are respectively mounted on the second major base and the major inserting head. When the major inserting head is close to a major insertion hole of the first base, a magnetic force is generated between the two major components to guide the major inserting head to close the major insertion hole and assist the major inserting head in inserting. After the major inserting head is inserted, the magnetic force also assists the major inserting head in staying in the engaging state.

An electronic lockbox uses a rotary actuator with multiple positions to achieve multiple locking states. Multiple positions of the actuator are detected, using optical sensors. The locking mechanism includes an outer sleeve and an inner cylindrical barrel that are coupled with torsion springs. The lockbox has a shackle and a key bin that are retained by the inner barrel when in the locked state, and the barrel can be rotated to either release the shackle or to release the key bin that typically holds a building's key.

Provided is a method, performed by an access authorisation verification apparatus, involving the steps of: obtaining a piece of information from a transmission; identifying a transmission data record using the piece of information obtained from the transmission, wherein the transmission data record comprises address information associated with the transmission; determining an access control apparatus on the basis of a comparison of the address information of the transmission data record with respective address information that is associated with the access control apparatuses and stored on the access authorisation verification apparatus; allowing selection and/or confirmation of an access control apparatus for the determined access control apparatus by a user of the access authorisation verification apparatus; and communicating access authorization information to the access control apparatus in order to gain access to a room associated with the access control apparatus, so that the transmission can be placed into or removed from the room.

A bag lock and its unlocking method, a first limiting slot is provided at a lock hook. The lock body comprises a lock bolt assembly and a rotating block, the rotating block has a locked state and an unlocked state; when the rotating block is in the unlocked state, the torsion spring provides a twisting force to disengage the first limiting slot from the lock bolt assembly, so that one end of the lock hook opposite to the torsion spring is unlocked from the lock hole to unlock the bag lock; when the rotating block is in the locked state, the rotating block limits a position of the lock bolt assembly so that the lock bolt assembly is kept to be locked inside the first limiting slot, thereby the end of the lock hook opposite to the torsion spring is fixed in the lock hole to lock the bag lock.

A parcel receptacle includes a bottom member, an exterior wall that extends upward from the bottom member and that defines an interior space, and a top member that is coupled with the exterior wall and configured to cover an opening of the receptacle to enclose the parcel within the interior space. The parcel receptacle also includes a lock mechanism that is operably coupled with the top member and the exterior wall. The lock mechanism is lockable to prevent user access to the interior space and is unlockable to enable the top member to be opened to allow user access to the interior space. A vertical lip of the top member overlaps at least a portion of the exterior wall so that a seam between the top member and the exterior wall is covered by the vertical lip.
