The present invention relates to a security locking system of the type comprising a cylinder (3) provided with a set of pistons (8) that are able to be positioned by elastic means on the impression formed in the edge (7b, 7c) of a control key (7) perpendicularly to the direction in which said key (7) is introduced into the cylinder (3), these pistons (8) being able to take up two positions, namely a position retracted into the cylinder (3) when the key (7) is introduced into the latter and an extended position when the key (7) is withdrawn there from. This system is characterized in that:—the cylinder is made up of a locking block (3) of parallelepipedal shape that is able to be received in a receiving block (5),—it comprises locking means which are activated when the locking block (3) is introduced into the receiving block (5).

The lock according to the invention is meant for locking cabinets, vaults and different machines. The lock has a lock frame, which comprises a bolt. A lock cylinder has been arranged in connection with the lock frame. The lock frame further comprises a power transmission mechanism between the lock cylinder and the bolt. The power transmission mechanism comprises a transmission lever and a latch. The transmission lever additionally comprises a retaining protrusion. The bolt comprises a locking pin and the lock frame additionally comprises a hole for the locking pin. The lock is arranged to allow movement of the lock cylinder and the power transmission mechanism in the direction of the longitudinal axis of the lock cylinder due to an external hit or drilling of the lock cylinder, whereby the movement in the direction of the longitudinal axis moves the retaining protrusion away from the locking pin. Thus, the end of the locking pin moves into the hole in the frame.

A lockable door hardware assembly for securing a door in closed configuration includes a mortice lock that is coupled to a door. The mortice lock comprises a latch bolt, which in turn comprises a head and a shaft. The head is circumferentially larger than the shaft. A strike plate is mounted to a doorframe in which the door is positioned. A channel extends into the door from an interior surface of the door so that the head of the latch bolt is positioned between the doorframe and the channel when the latch bolt is extended through the strike plate. A rod is selectively insertable into the channel. The rod is positioned to abut the head of the latch bolt to prevent the latch bolt from retracting from the strike plate, thereby rendering the door unlockable from either side of the door.

A base member for a tablet computing device including a fastener to removably couple a tablet computing device to the base. A receptacle can receive a security lock to secure the base, wherein the security lock is to prevent the fastener from releasing the tablet computing device in a first mode and allows the releasing of the tablet computing device in a second mode.

A door lock assembly includes a door lock that is installed in a door of a building. The door lock includes a pair of door knobs and a latch bolt. The latch bolt engages a recess in a doorjamb when the door is closed for retaining the door in a closed position. Conversely, the latch bolt disengages the recess in the doorjamb when either of the door knobs is rotated thereby facilitating the door to be opened. A pin is extendable though the latch bolt of the door lock when the door is closed such that the pin abuts the door. In this way the latch bolt is inhibited from being urged into an unlocking position thereby inhibiting an intruder from defeating the door lock and opening the door.
