Abstract:
A circuit pack handling system comprising:a handle assembly storage pocket formed in the sidewall of a circuit pack; a carrying handle assembly hinge-mounted within the pocket and adapted to retract substantially within the storage pocket, the handle assembly comprising: at least two legs, an inner leg and an outer leg, of substantially equal length hinge-mounted at their circuit pack ends within the pocket; and a gripping member hinge-jointed to the extended ends of the legs to form the carrying handle assembly, whereby the legs range between a stored position inside the storage pocket and substantially parallel to the sidewall, and a deployed position outside the storage pocket and substantially perpendicular to the sidewall, the legs pivoting about the sidewall hinge pins with the handle assembly maintaining a substantially parallelogram configuration with the sidewall, the gripping member moving horizontally while remaining substantially parallel with the sidewall; and a handle locking sub-assembly affixed within a backplane end of the storage pocket between an inner wall of the pocket and the inner leg of the handle assembly so as to lock the handle assembly into the deployed position, the sub-assembly comprising: a leaf spring housing top section; a leaf spring housing bottom section; a leaf spring housed within the leaf spring housing sections; a locking member hinge-jointed at one end to the inner leg and the circuit pack end being adapted to interact with the sub-assembly; and a locking cavity formed in the leaf spring housing top and bottom sections and adapted to entrap the circuit pack end of the locking member so as to lock the handle assembly into the deployed position.
