A latching system includes a guide body, and a latch rod slidably retained by the guide body. Latch assemblies fixed to the latch rod, are spaced apart from one another, and independently biased to a latched position. A first rod-biasing spring is coaxial with the latch rod and disposed between the guide body and a first latch assembly. The first rod-biasing spring biases the latch rod to a rest position corresponding with a latched position of the latch assemblies. Multiple catches are secured at a spacing equal to a spacing of the latch assemblies on the latch rod such that the latch assemblies latch to the catches independently of one another. A force on the latch rod against the first rod-biasing spring moves the latch rod along the longitudinal axis of the latch rod from a rest position to an actuated position and unlatches the latch assemblies simultaneously.

The invention relates to an electromagnetic door opener comprising a housing for installing in a door frame, a pivotable cover which can be rotated between an open position and a closed position, and a security device operating counter to a forced rotation of the cover from the closed position into the open position, which comprises a primary security step and a secondary security step. Said door opener is characterized in that the secondary security step comprises a locking element which is supported in a form fit on the base of the housing of the door opener housing.

The present invention is a security display case comprising: an enclosure having a plurality of sidewalls defining a safe portion, one of the sidewalls having an opening formed therein; at least a pair of panels hingedly attached over the opening of the enclosure, at least one first locking mechanism disposed on a first panel of the at least a pair of panels and a second locking mechanism disposed on a second panel of the at least a pair of panels; a display housing moveable in and out of the safe portion of the enclosure; at least one locking assembly mounted within the enclosure to facilitate locking and unlocking the display housing within the enclosure; and a control system for operating the movement of the display housing and the locking assembly.

A door locking device is applied to an electronic apparatus including a hinged door arranged in an opening portion of a casing. The door locking device includes a key cylinder and a pivot hook. When the door is closed and a movable element of the key cylinder is at a locked position, the pivot hook is caught on the casing to prevent the door from being opened. The door locking device further includes a rod member crank-coupled to the movable element of the key cylinder on an inner side of the door and configured to be displaced by interlocking with the movable element. When the door is closed and the movable element is at the locked position, a distal end (roller) of the rod member is held in contact with a rod receiving surface formed in the casing. Thus, the rod member keeps a closed state of the door.
