Abstract: A telescopic counterbalance for a hinged closure includes inner and outer telescopic members which are biased apart to their telescopic outward position. Bearing arrangements on the inner end of each member slidably bear on the other member. The members are located in extended position by a plurality of depressions on the outer member engaged by an integral collapsed rib on the inner member. The depressions and rib are located intermediate the bearing arrangements and the ends of the member to space the bearing arrangements and increase the bending strength of the counterbalance.

Abstract: A closure operator particularly adapted for use with a station wagon tailgate type closure and adapted to permit randomly interchangeable operation of the tailgate in either one of a power mode and a manual mode, the closure operator including a driving member movable from a center position in opening and closing directions corresponding to movement of the closure toward an open position and a closed position, means defining a slot in the driving member, a driven member connected to the closure for moving the latter in the power mode and having a pin thereon engageable on the driving member in the slot, a reversible electric motor for moving the driving member in either one of the opening and closing directions, and a control circuit having a first manually actuable switch for energizing the motor to move the driving member away from the center position in either the opening or closing directions and a second switch responsive to the position of the driving member for reversing the motor to bring the driving member back to the center position and sequencing means for preventing reversing of the motor through the second switch until the first switch is deactuated. In the center position of the driving member the pin is located adjacent one or the other of the ends of the slot when the closure is in the open and closed positions so that movement of the closure in the manual mode effects lost motion between the driving and driven members as the pin traverses the length of the slot while movement of the driving member effects engagement between an end of the slot and the pin to effect movement of the driven member and the closure in the power mode.
