Abstract
A securing device for releasably attaching the columns or legs of chairs, tables and the like. The securing device is fixedly mounted to the underside of the chair seat or table top and includes a receiver in which the column or leg is inserted. A gripper shoe can be advanced radially against the column to hold it in place. The radial displacement of the gripper shoe is caused by the force exerted by an eccentric stack of discs of different size which are assembled into an integral body that is rotated about an axis, thereby forcing the larger eccentric discs into camming engagement with mating extensions of the gripper shoe. Upon release of the eccentric, the column may be pushed out of its receiver by the upward motion of a handle which pivots about a ball joint resting on the eccentric body and exerts an axial downward force on the column to be removed.
