Coupling for Quick Attachment to Plate-Like Structure.

Pagination or Media Count:
A coupling which is readily attachable to a plate, panel or like structure includes a rotatable shaft for thrusting a bearing element through a circular hole in the structure when the bearing element and the hole are in concentric relationship. Thereafter, the shaft is rotated by less than a complete revolution to bring the bearing element and the hole into a selected eccentric relationship, and also to activate a locking mechanism to maintain the eccentric relationship. When the bearing element and hole are in the eccentric relationship, a bearing surface of the bearing element abutts the structure to impose substantial force thereupon. Author
