ABSTRACT:
A support rod is maintained in position by two load-bearing leaf springs disposed at each end of the rod. The leaf spring members are partially U-shaped in cross-section and the rod is maintained with a loop formed by the U and a back plate. This loop is under a predetermined tautness, the strength of which is created by presetting the tension of a coil spring on the upper flat portion of the load-bearing leaf spring member from which the U-shaped section extends. When an overload is placed upon the support rod, the weight causes the rod to move the U-shaped section of the leaf spring outwardly which thereupon releases the rod from its engagement within the U-shaped loop. As a consequence, the rod will fall with the weight thereon under the force of gravity.
