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.
In an apparatus for securing chair or table columns or the like to the underside of chair seats, table tops or the like, said apparatus including a securing device capable of attachment to the underside of the chair seat or table top or the like and having a bore for receiving the upper end of said column, said securing device including a gripper shoe which is radially displaceable with respect to the column and can be pressed against the column, thereby immobilizing the column with respect to said securing device, the improvement wherein said securing device includes an eccentric body disposed on the side of said gripper shoe remote from said column, said eccentric body being pivotable about an axis and bearing on one side against said gripper shoe and on the other side against a wall of the securing device, and wherein said eccentric body is fixed at the top by means of a bearing assembly disposed between said eccentric body and said chair seat or table top and extending into a pivotable operating lever.
