Abstract
An adjustable grip latch has a slippable, friction-type drive connection provided between a shaft and a pawl which is carried on the shaft. A stop extends alongside the shaft for limiting the travel of the pawl to a range of movement extending between latched and unlatched positions. When the pawl is in its latched position it engages one portion of the stop. When the pawl is in its unlatched position it engages a different portion of the stop. The slippable drive connection transmits only a limited amount of torque from the shaft to the pawl, thereby enabling the shaft to move the pawl between its latched and unlatched positions, and enabling the shaft to rotate relative to the pawl when the pawl has engaged the stop. The slippable drive connection utilizes a wave spring washer to effect transmission of limited torque from the shaft to the pawl.
