ABSTRACT:
A spring stretcher for stretching furniture springs, such as no sag springs, commonly found in sofas, lounge chairs and the like. This spring stretcher stretches a replacement spring in an obstructed environment, thus will stretch a replacement furniture spring without having to remove the upholstery from the piece of furniture. The spring stretcher includes a ratchet mechanism having a barrel threadably attached to one end of the ratchet mechanism and a telescoping rod is inserted through the opposite end of the ratchet mechanism which passes through the ratchet mechanism and is fed into the barrel. A hook is fastened to the end of the barrel opposite its threadably attached end and another hook is fastened to the exposed end of the telescoping rod. The hooks rotatably fastened to the device further enhance its application in a confined area. The spring is secured at each end to one of each of the hooks. As the ratchet mechanism actuates the telescoping rod, the two hooks diverge to stretch the spring. Once the spring has reached a desired length, a quick release is provided to relieve the tension on the spring.
