<p>Apparatus for rigidly coupling a first member to a second member along a longitudinal axis while avoiding line contact therebetween and providing a positive disconnect action to avoid hangup or stick with prolonged usage wherein one of the members (100) carries a pair of wedges (131, 132) coupled to opposite threaded ends of a differential screw (130). The other one of the two members (110) includes a reaction surface (111) confronting wedging surfaces (133, 134) on each of the two wedges. Upon rotation of the differential screw, the wedges are moved in opposite directions to bear against the reaction surface with substantially a surface area contact to force the first and second member into rigidly coupled engagement. Upon rotation of the differential screw in an opposite direction, the wedges are positively moved in reverse opposite directions to effect coupling.</p> |
