ABSTRACT:
A spring-tightened bayonet-type connection for securing an accessory (for example, a flash unit) to a camera housing. A threaded pin or bolt on the accessory carries a cross bar or head of non-circular shape which can pass, in one position of orientation, through a similarly shaped opening in the camera housing. When the bolt is turned, the ends of the cross bar engage behind the edges of the cavity in which the cross bar is received, and the screw thread action of the bolt draws the cross bar against the engaging parts of the camera to draw the accessory firmly against the camera housing. A spring pressed rack meshing with a pinion on the bolt tends to turn the bolt in a tightening direction. A plunger operated latch holds the rack in a spring tensioned position where the bolt is loose and its head or cross bar is oriented to pass into or out of the cavity in the camera. When the accessory and the camera are brought together, the latch is automatically released, allowing the spring pressed rack to tighten the bolt.
