Quick-Disconnect Fastener

Proposed quick-disconnect fastener for two or more parts resists shear loads and torque. Device centers parts to be joined, clamps and tightens them into single unit. Potential applications for removable fastener include holding parts for welding, brazing, soldering, riveting, and gluing. Other possible uses are for attaching removable panels and panels with poor access on one side and plugging leaks in pressure vessels.

Ball Joint for Quick Connections and Disconnections

Joint is strong in shear and tension. When release tool is inserted into sleeve of joint, locking balls engage sleeve and allow it to be pulled upward compressing spring and releasing collet fingers. When sleeve is released, spring forces sleeve and collet fingers over ball on fixed part of joint.
