Abstract: A coupling assembly includes a female member having a bore and a male member capable of being received in the bore of the female member. A trigger assembly is disposed between the male and female members and includes an actuator, housing, and biasing member. The male member includes an engagement mechanism to engage the trigger assembly and facilitate axial movement of the actuator. Axial movement of the actuator induces expansion of the biasing member and the engagement of the actuator and the male member. Accordingly, the male member is urged or propelled into the bore of the female member upon expansion of the biasing member. To disconnect, the male and female members are utilized to return the trigger assembly to an inactivated position.

Abstract: A shipping rack for flat glass sheets and the like including a base for supporting the sheets on edge and an integral inclined rear wall against which they are supported. Vertical corner posts are affixed to the base behind the inclined wall. A removable split gate, comprised of two individual sections having interconnecting cross bar segments, is provided at the front of the rack. The rear frame is adapted to store the individual sections of the front gate when not in their working position, whereby the gate sections remain with the rack and a number of empty racks can be stacked in nested relationship for storage and return shipment.
