Abstract

See full text

A device for connecting springs together to define a support surface includes four arms each which extend in an outward radial direction from a center of the connecting device, the length of each arm defined by two sides extending in spaced relation to one another. Each arm includes a stiffening portion extending in a widthwise direction between the sides of the arm and extending from an end thereof towards the center of the connecting device only partially along the length of the arm. The straight sides of each arm have identical height dimensions and the stiffening portion has a lesser height than the height of the sides. The sides and the stiffening porting of each arm together define a planar surface of the arm and a finger portion extends from the end of the arm to define with the planar surface a U-shaped recess for gripping a top coil of a coil spring. The four arms define an X-shaped connecting device and further define an X-shaped opening extending through the connecting device which is approximately one-half the size of the X-shaped connecting device. Alternatively, the four arms define a circular opening extending through the connecting device.
