Abstract

A truck body compartment lock including in combination, a housing having a manually operated lock; two way solenoid means adapted to operate the latch mechanism between the locked and un-locked positions independently of manual operation; a link between the solenoid actuator and the latch mechanism, adapted to accommodate and cooperate with a barrel mechanism of the manually operated lock by having a specially configured void or cut-out portion with inserts to fit in the voids, and wherein in operation, the lock can be locked or un-locked by providing electrical current to the solenoid or manually by key operation according to the positioning of a locking tongue of the barrel within the void or cut-out portion. There is provision for a kit of parts to modify existing prior art compartment locks to affect the same function.

Abstract

A method of making a seating structure comprising a frame (86) and a membrane (14) supported on the frame under tension is disclosed. A pair of side frames (12), each define a front face (18), a rear face (20) which defines at least one open channel (24), and a curved outer edge portion(16) joining the front and rear faces, A sheet of membrane has a bead secured to each opposed side edge of the sheet by passing the membrane around the bead and stitching it to itself to form a tube. The PVC is a relatively rigid grade of PVC and is rectangular in cross-section. The bead is free to move along the tube. The beads are inserted in the open channels along the rear face of both side frames with the longer axis of the bead directed into the channel. Then the side frames (12) are moved apart on a hydraulic jig to tension the membrane. Tension in the membrane (14) does not cause the bead to come out from the open channel due to the relative length of the longer axis of the bead and the shape of the channel. Since tension tends to cause the bead to rotate about the outer edge of the opening of the channel (24), a protrusion (32) is define in the channel to resist such rotation. Because of the shape of the bead and channel, and the fact that tension applied to the bead tends to cause the bead to rotate rather than be pulled out in the direction of the applied tension, the bead can be a relatively loose fit in the channel. This allows for ease of insertion of the bead in the channel even where several layers of membrane are used and wrapped around the bead. Typically, the bead is heated before being inserted in the channel to allow it to deform sufficiently to match the contour of the side frame (12).
