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° away from the direction of the fence tension. A process for installing the fence and gate is described.

Claims

1. A lightweight fence and gate for swimming pools surrounded by a deck comprising a plurality of poles adapted to be inserted into the pool decking adjacent said pool;

a mesh screen tensioned between said poles having top and bottom bindings;

a gate in said fence including a frame having a pair of spaced upright support members, a first horizontal brace for spacing the upright support members and a length of mesh screen tensioned between said upright support members;

support means capable of withstanding lateral tension forces of said screen for supporting and latching said gate;

hinges secured to said support means on one side of said gate; and

a latch device secured to said gate and to said support means on the opposite side of said gate.

2. A lightweight fence and gate as claimed in claim 1 wherein said hinges have internal gate self closing springs.

3. A lightweight fence and gate as claimed in claim 1 wherein said latch device includes a magnetic latch tending to pull said gate closed and latched.

4. A lightweight fence and gate as claimed in claim 1 wherein said support means includes on each side of said gate a pair of poles inserted into the pool deck in close proximity to each other with cross members attached to both of said pair of poles.

5. A lightweight fence and gate as claimed in claim 4 wherein said poles are secured to the pool deck at a small angle opposing the tension force of said mesh screen.

6. A lightweight fence and gate as claimed in claim 4 wherein said gate includes a generally U-shaped frame opening upwardly with said first horizontal brace secured to the lower ends of said upright support members and a second horizontal brace secured to said upright support members on the pool side of said mesh screen at a height well below the top of said gate fabric.

7. A lightweight fence and gate as claimed in claim 4 wherein said latch device includes a magnetic latch tending to pull said gate closed and latched.

8. A lightweight fence and gate as claimed in claim 4 wherein said latch device includes a ferromagnetic rod carried on one of said poles of said support means and said gate and a magnet having a socket secured to the other of said poles of said support means and said gate for receiving said ferromagnetic rod.

9. A lightweight fence and gate as claimed in claim 8 wherein said latch device includes manual means for disengaging said ferromagnetic rod from said socket.

10. A lightweight fence and gate as claimed in claim 9 wherein said latch means includes a key operated lock for preventing said ferromagnetic rod from being disengaged from said socket.

11. A lightweight fence and gate for swimming pools surrounded by a deck comprising a plurality of poles adapted to be inserted into said deck adjacent said pool;

a first length of mesh screen tensioned between said poles defining the pool fence;

a gate in said fence including a generally U-shaped frame opening upwardly having a pair of spaced upright support members and a second length of mesh screen tensioned between said upright support members of said gate; and

support means to which said first length of mesh screen is attached for supporting said fence and gate and latching said gate including a truss structure capable of isolating the lateral tension forces of said first length of mesh screen on opposite sides of said gate.

12. A lightweight fence and gate as claimed in claim 11 wherein said poles are set in openings in said pool deck at a small angle to the vertical opposing the tension force of said first length of mesh screen.

13. A lightweight fence and gate as claimed in claim 11 wherein said latch device includes a ferromagnetic rod carried on one of said truss structure and said gate and a magnet having a socket secured to the other of said truss structure and said gate for receiving said rod.

14. A lightweight fence and gate as claimed in claim 13 wherein said latch device includes manual means for disengaging said ferromagnetic rod from said socket.

15. The method for installing a self closing gate in a tensioned removable swimming pool fence comprising a plurality of poles interconnected by flexible mesh fencing comprising:

inserting a series of said plurality of poles into a deck surrounding a swimming pool with the flexible mesh fencing in tension to maintain the fence in tension;

the first and last poles of said series of poles defining a gate opening;

said first and last poles each constituting a pair of poles interconnected to each other to define a support structure capable of absorbing the tension of the flexible mesh fencing;

fabricating a gate including a pair of side rails, a cross rail and flexible mesh tensioned between said side rails;

hinging the first of said pair of side rails of said gate to the first of said pair of poles; and

installing a latch between the second of said pair of side rails of said gate and said last pole of the tensioned fence;

whereby the gate is free to open and close without interference by the tension of the mesh of said fencing.

16. The method in accordance with claim 15 wherein said plurality of poles are removably secured to the pool deck by drilling holes at intervals sufficient to tension the mesh between adjacent poles and the deck and introducing the lower end of adjacent poles into successively drilled holes;

wherein the holes in the deck adjacent to the gate location are drilled at a slight vertical angle away from the direction of tension applied by the mesh fabric.

17. The method in accordance with claim 15 wherein the gate is installed by drilling a pair of holes on each side of the gate location, one for each pole of the pair of poles.

18. The method in accordance with claim 15 including securing the poles of each pair together to define a fencing tension absorbing support for the gate.

19. The method in accordance with claim 18 wherein the step of securing the poles of each pair together comprises attaching at least one rigid strap between poles.
