Apparatus to axially hold a featureless shaft has an abutment for abutting the side of the shaft and a cam to wedge the shaft against the abutment. The cam has a convexly radiused face which is generally opposed to the abutment. The generating radius for the face is offset from the pivot axis of the cam in the direction in which a shaft is inserted into the apparatus. Consequently, once the cam wedges the shaft against the abutment any withdrawal force on the shaft will tighten the wedging effect since the eccentric radiused face will attempt to move closer to the abutment.

Linear latch

Apparatus for deploying an articulated panel array comprises a spring motor between adjacent panels and a latch between adjacent panels. The latch between a given pair of panels is released by an abutment on the panel which is adjacent to the pair and toward the proximal end of the array only when the more proximally disposed panel of the pair moves to its fully deployed position. With this arrangement, only a single group of panels of the array moves at any given time providing an accurate deployment envelope.
