Automatic gate closer latch
摘要:
An automatic gate closer latch for use in centrally securing a commercial or industrial swinging gate to a stationary fence post, especially useful in the farming and ranching applications, includes a gate catcher assembly mounted on a swivel bolt, complete with directional pressure finders, a bearing tensioner assembly consisting of a bearing tensioner plate, a roller bearing, a tension spring and mounting hardware. The said gate latch catcher assembly is a flat bar segment composed of three right angled bends designed similar to open fingers, to catch the oncoming protruded gate edge post. The directional pressure fingers incorporated in the opposite ends of the gate catcher finger assembly allows the spring tension assembly to maximize its distance in the central neutral position thus causing an automatic closed latch phenomenon. Above normal pressure from an implement on either side of the gate will promote the fingers to open allowing the gate to swing open. The bearing tension assembly consists of a tension spring encircling an all thread bolt promoting pressure to the end roller bearing, all mounted perpendicular to the gate catcher assembly in a sliding tensioning phenomenon through two angle irons mounted on the flat bar mounting irons.
