Abstract: A locking system (20) allows a plurality of vehicle service doors (22) to be locked and unlocked by operating a single electrical switch in a suitable location such as the vehicle cab. The locking system (20) includes a lock (24) having a bolt (26) and a blocking cam (40). An actuator (144) moves the acm (40) between locked and unlocked positions via an extension member (46). The actuator (144) includes an actuating member in the form of a combined piston (148) and rack (150). A spring (170) urges rack (150) to remain in either of two selected positions.

Abstract: Vehicle desks (20, 220) are disclosed which are spaced from a front vehicle seat (32) to present the work surface (24) of a rotatable shelf (52) to the driver or the front seat passenger. A rotatable arm (58) facilitates placement of the shelf in a convenient position. When not needed, the major portion of the desk is easily removed from the vehicle.
