  • Patent number: 5664769
    Abstract: A gate assembly for tensioned fences, particularly those which encircle home swimming pools and are removable for swimming pool use. The gate in its preferred form is "U" shaped with no rigid bar at the top and has the space between the bars of the gate filled with tensioned mesh fabric similar to the tensioned fence. The gate is supported by poles on each edge which provides spring closed hinging on one edge and an automatic latch at the opposite edge. The poles are in fact pairs of poles at each side which together react to the tension of the fence without transferring the fence tension to the gate. In one form, the two poles at each edge are rigidly connected by bars which define a truss. The gate supporting poles are secured to the pole decking as by insertion in drilled holes which are at cant angles in the order of 5.degree. away from the direction of the fence tension. A process for installing the fence and gate is described.
