发明名称 Gate closure mechanism
摘要 Invention is directed to a compression spring mechanism, particularly in combination with a fencing system which incorporates a swinging gate. The mechanism, intended to automatically close a released and opened gate, comprises a cylindrical tube, mounted within the gate, a plurality of compression springs aligned end-to-end within the tube, and a spring housing secured to one end of the tube for receiving one of the compression springs. A cable, of predetermined length, passes through the housing and aligned springs and is secured to the spring end most remote from the spring housing. The other end of the cable is secured to a stationary member, such as a post about which the gate pivots. As the gate is opened, the springs are further compressed storing sufficient energy to allow closure of the gate when released.
