A door assembly for selectively interlocking opposing doors each pivotably mounted at a hinge side thereof to a door frame so as to both open and close in the same direction includes a door handle assembly mounted to one door at a latch side thereof opposite the hinge side and carrying a first plurality of magnets, and another door handle assembly mounted to the other door at a latch side thereof opposite the hinge side and carrying a second plurality of magnets. The door handle assemblies are arranged relative to each other with the first and second pluralities of magnets aligned such each aligned pair of the first and second pluralities of magnets have opposite magnetic polarities, and the aligned first and second pluralities of magnets magnetically couple to each other as the door handle assemblies are brought into contact with each other.

A lock having a rotatable auxiliary positioning structure is adapted to connect with a latch element which includes a drive orifice, and the lock contains: a first locking assembly and a second locking assembly. The first locking assembly includes a transmission unit and a guide seat, the guide seat has at least one guiding extension. The second locking assembly includes a driving element, and a connecting position is defined between the first locking assembly and the second locking assembly in a rotatable direction. At least one of the transmission unit and the driving element is rotatably received in and drives the drive orifice of the latch element, the at least one guiding extension is configured to be connected with the latch element and to guide the first locking assembly to be positioned on the connecting position along the rotatable direction opposite to the latch element.

Described is a handle (10) with floor and/or ceiling lock which comprises: a first part (11) and a second part (12) one having an internal cavity (14); a connecting element (15) having two opposite ends (151, 152) to each of which can be fixed one of the parts (11, 12); a closing/opening device (17) comprising a knob element (18), a latch element (19) and a transmission mechanism (20) which connects them.

The second part (12) has a housing seat (22) for a Mortise cylinder unit (100) which has a lever (101) which is rotatable with respect to tan actuation axis (A).

The transmission mechanism (20) comprises a crank element (23) configured in such a way as to transform a rotation of the knob element (23) into a translation of the latch element (19) with respect to the cavity (14).

The crank element (23) faces in the housing seat (22) in such a way that a protrusion (231) of the crank element (23) interferes with a trajectory of rotation of the lever (101) of the Mortise cylinder unit (100) for operating the latch element (19).

The disclosure relates in general to a locking mechanism for a door. Specifically, the disclosure relates to a thumbturn latching mechanism having a triggered rotation-arresting assembly therein, configured to inhibit rotation of the lock mechanism upon unauthorized removal of the posterior portion of the latching mechanism, while still allowing for selectably bypassing the rotation-arresting mechanism from the anterior portion of the locking mechanism.

The invention relates to a flat key (1) for a cylinder lock (11), said flat key comprising: a key bow (2) and a key shaft (3) that extends substantially parallel to a key longitudinal axis (L) and has a key tip (4), wherein at least one surface coding (6) designed to be read in the cylinder lock (11) is located at the end face (5) of the key tip (4); and a cylinder lock (11) for receiving such a flat key (1), and a locking system comprising one or more such flat keys (1) in combination with one or more such cylinder locks (11).

A lockset with a sliding spindle assembly allows ingress using a key on the outside or a button on the inside. The sliding spindle assembly provides first and second sliding mechanisms operated from the outside and inside, respectively, that operate a clutch to couple the outside handle to the main spindle. Each sliding mechanism comprises a key cylinder or twist and/or push button lock that rotates a cam to linearly advance (slide) a cam follower that incorporates a spindle receiver. The first sliding mechanism slides its spindle receiver between clutching and non-clutching positions with respect to the main spindle. The second sliding mechanism slides the main spindle itself between clutching and non-clutching positions with respect to the first sliding mechanism's spindle receiver. The sliding spindle assembly can be incorporated into a legacy lockset and also be used in a double-latch lockset.
