Abstract: A lock mechanism for sealing a goods compartment has a housing (10) supporting a shackle (62) movable between open and closed positions to permit hoops on the ends of an elongate sealing member (44) to be connected thereto and then held thereby. The shackle (62) is retained in its closed position by a spying loaded push-button (32) and also by an auxiliary lock (64) including an electric actuator (71) controlled by a control unit (15). The housing (10) has a display device (17, 18, 19) to indicate the lacking condition and sealing of the mechanism and also has a proximity card reader adapted to read information from a presented smartcard, operation of the auxiliary lock (64) being controlled by presentation of an appropriate smartcard.

Abstract: A security system for a goods-carrying compartment such as of a vehicle is arranged to indicate the sealed status of an access door 40 to the compartment. Following loading of the compartment, the system is used to seal the door closed by passing a security cable 34 through components 46, 50 of a lock mechanism associated with that door. The cable 34 is re-entered into the system housing 30 and then, using a key inserted into a security switch 14, the system is activated to show proper sealing. An interrogation switch 12 may be pressed to illuminate LED 22 if the door 40 has not been opened following sealing or LED 24 if the door has been opened and not properly re-sealed with a key. Two different keys may be provided, one for use with the initial sealing of the compartment and the other for re-sealing by an authorized person such as a driver, so long as the compartment was opened for a legitimate purpose on route between dispatch and the ultimate destination.

Abstract: A locking mechanism for a hinged door comprises first and second actuators having first and second bolts associated therewith, each said bolt being movable between free and locked settings. The first actuator is adapted for mounting on a frame for the hinged door, and the second actuator is adapted for mounting on the door at a location spaced from the first actuator. A drive mechanism interconnects the second actuator with the first bolt when in its locked setting, such that operation of the first actuator to move the first bolt to its locked setting causes operation of the second actuator to move the second bolt to its locked setting.
