  • a feature of the invention is the provision of the novel means for supporting the water filled pool liner 12 above ground level under pressure of the water, particularly in the assemblage of the bottom steel channel frame 16 of FIGURE 4 and the top steel channel frame 14 of FIG- URE 5, as hereinafter explained.
  • a stake On assembling the pool structure of FIGURE 1, a stake may be placed in the ground at each corner where the pool structure is to be placed. The ground is then scraped level in all directions in the staked out area. The steel channel bars for the bottom frame 16 are then placed as shown in FIGURE 4, on the scraped level area with U of the channel bars 40, 41, 42 and 43 laying with the open side up.
  • the drain pitch for the bottom 27 of the pool liner 12 may be effected by scraping the ground so as to pitch the level gradually from each of the four sides, making the depth approximately six inches lower at the center drain 32 while the bottom of the U channel bars will be about six inches above the center of the pool and thereafter placing sand within the confines of the bottom frame 16 so formed as to effectively pitch the level of the sand bottom from the sides to the pool drain 32, to the desired incline, as best shown in FIG. 3.

  • a steel bracing strap or straps 51 are placed under the side channel bars 4% ⁇ and 42 and bolted thereto by high tensile bolts 53 and 55.
  • end channel bars 41 and 43 are now back fastened to the side channel bars 40 and 42 by a suitably flat steel fish plaate 48 fastened thereto by suitable high tensile bolts 50, having hand tightening nuts on top as best shown in detail in FIGURE 8.
  • the assembled bottom channel frame 16 is leveled and then the plywood panels 25, shown in FIGURES 1, 3 and 7, are set edgewise in the ground inside the bottom channel frame 16 and against the U channel bar of the frame 16 with the smooth side of the plywood panel 25 facing out.
  • a series of Wooden supporting posts 52 and 54 extend vertically from the channel bars of the bottom frame 16 with the lower ends of the posts 52 and 54 standing in the U channel of the bars of the bottom frame 16.

  • Channel bars 60, 61, 62 and 63 of the upper channel bar frame 14 are next assembled on the top end of the supporting posts 52- and 54 with the U of the channel bars 60, 61, 62 and 62': of the upper frame 14, laying with the open side down on the top of the posts 52 and 54, as shown by FIGURE 3.
  • the end channel :bars 61 and 63 are set at right angles to the side channel bars 60 and 62 as shown in FIGURE 5, with the end channel bars being fastened to the side channel bars at the corners of the upper frame 14 by a suitable flat steel fish plate 68 fastened thereto by suitable high tensile bolts 70, as shown in detail by FIG- URE 6.
  • the fish plate 68 is thus bolted to the top of the corner with the heads of the bolts 70 on top. All corners of the upper frame 14 are similarly connected.

  • camber bars 75 and 77 thus serve to flex or arch the steel channel bars 60 and 62 inwardly so as to provide a flexural top channel bar frame 14 of greater strength for supporting, in cooperative relation with the bottom channel bar frame 16, the pool liner 12 above the ground level and under pressure of the water carried within the liner 12, as will be hereinafter explained.
  • a steel angle bar 83 is then set vertically in each corner of the upper and lower channel bar frames 14 and 16 inside the respective frames and between the plywood walls 25 and the inside flange of the U channel bars of the upper and lower frames 14 and 16. It may be necessary to shift the existing plywood wall 25 to cause the inside corners of the plywood to just meet, while the vertical steel angle bar 83 is positioned so as to be flush to the upper edge of the top of the U channel bar of the upper frame 14, as shown by FIGURES 7 and 9.
  • the plywood panels 25 are nailed to the wooden supporting posts 52 and 54 before they are set in the steel corners of the frame structures, as shown by FIGURES 1 and 3.

(Cl. 4172) ABSTRACT OF THE DISCLOSURE An above ground swimming pool assembly, including top and bottom frames for supporting in a locking relation opposite ends of suitable supporting posts extending between the top and bottom frames and in a contacting supporting relation with outer surfaces of sidewall means for the pool, a liner for carrying the water of the pool above the ground level, together with means carried by the top frame for securing an upper edge of the liner adjacent the top frame, camber bar supporting means for the top frame to permit a pool construction of greater size and water capacity, and an outrigger means carried by the supporting posts extending between the top and bottom frames for supporting a pool deck and a safety fence extending around the pool and deck above the ground level, and a hinged ladder means leading from the ground level to the deck and which ladder means may be raised to prevent non-permissive access to the deck and pool, as by small children so as to protect them from accidentally falling into the pool.
This invention relates generally to a swimming pool assembly and means for supporting sidewalls of the pool and more particularly to a novel swimming pool assembly that may be erected above ground and including novel camber bar supporting means for the sidewalls of the pool providing greater sidewall strength to prevent distortion and bursting of the sidewalls and permit a construction of a pool of greater size and water capacity.
Heretofore, above ground swimming pools have been limited to pools of relatively small size and water capacity due to limitations in the strength of the sidewalls and extremely high pressures exerted by the water within the pool on the sidewalls of the pool with increase in the size and volumetric water content of the pool.
An object of the invention is to provide an above ground swimming pool of a simple construction that may be readily assembled with no special tools or skills and with novel sidewall supporting camber bars providing superior strength and support to prevent distortion and bursting of the sidewalls of the pool under the pressure of the water contained therein.
Another object of the invention is to provide an improved swimming pool construction including novel top and bottom frames of steel channel bars for supporting a liner for the pool above ground level.
Another object of the invention is to provide in combination with such novel bottom and top frames of steel channel bars, a novel steel strap arrangement for supporting the corners and intermediate portions of the bottom channel bar frame, and a novel flat steel camber bar arrangement for flexing or arching the channel bars of the top frame inwardly so as to provide a flexural top channel bar frame for supporting in cooperative relation with the bottom channel bar frame a liner for the pool above ground level and under pressure of the water carried within the liner of the swimming pool.
Another object of the invention is to provide a novel steel frame for supporting a swimming pool liner which may be readily assembled by merely bolting the several elements of the frame together so that the structure of the pool may be rapidly erected above ground by other than skilled workman.
Another object of the invention is to provide a novel supporting frame for a liner of a swimming pool in the provision of top and bottom steel channel bar frames interconnected by steel angle bars to effect automatic alignment and squaring of all components in the ready assembly thereof.
Another object of the invention is to provide in such a novel supporting frame for a liner of a swimming pool a series of supporting posts assembled between the top and bottom steel channel bar frames for supporting a pool deck and safety fence extending around the pool deck.
These and other objects and features of the invention are pointed out in the following description in terms of the embodiments thereof which are shown in the accompanying drawings. It is to be understood, however, that the drawings are for the purpose of illustration only and are not a definition of the limits of the invention, reference being had to the appended claims for this purpose.

FIGURE 11 is a top plan View of a modified form of the bottom steel channel bar frame of FIGURE 4 to be used in the assembly of a pool structure of the type shown in FIGURE 1 of a greater water capacity; and
FIGURE 12 is a top plan view of a modified form of the top steel channel bar frame of FIGURE 5 to be used with the frame of FIGURE 11 in the assembly of a pool structure of the type shown in FIGURE 1 of a greater water capacity.
Referring to the drawings and particularly FIGURES l and 2, there is shown a swimming pool construction 10 embodying the present invention and mounted above ground level 11. The pool 10 includes a fluid tight liner indicated generally by the numeral 12 and carried above the level of the ground by a novel assembly of a rec tangular top frame 14 of steel channel bars supported by a corresponding rectangular bottom frame 16 of steel channel bars resting on the ground level, as shown in FIGURE 3.
The liner 12 may be of any suitable flexible sheet material that is somewhat stretchable, and a vinyl plastic material such as polyvinyl chloride has been found to be very satisfactory. Along the upper or top free edge of the liner 12 there is provided an extruded bead that is snapped into a liner lock strip 18 and wedged therein in a conventional manner. The lock strip 13 is fastened by suitable means to the underside of an inner joist 2t] supporting a pool deck, as shown in FIGURE 3 and explained in greater detail hereinafter. This construction permits the replacement of a worn or damaged liner 12 without any disassembly of the supporting structures of the pool 10.
The liner 12 has a vertical portion 22 which is adapted to be pressed against the inner surfaces of sidewalls or plywood panels 25. Each of the panels 25 has an upper edge mounted in a suitable channel 28 provided in joists 20. The panels 25 are positioned between the joists and the ground level, as shown in FIGURES 1 and 3, and serve not only to lock the plywood panels in a vertical position but also to automatically align and prevent any shifting of the pool deck.
The portion 22 of the liner 12 maybe spaced somewhat from the inner surface of the panel 25 when installed prior to the filling of the pool with water. When the pool is filled with water this portion 22 of the liner 12 will be stretched somewhat and pressed tightly and smoothly against the inner surface of the sidewalls 25 without wrinkling under the pressure of the water.
The bottom portion 27 of the liner 12 will also be stretched and pressed tightly under the pressure of the water filling the pool against a sand bottom 30 suitably formed so that the bottom portion 27 of the liner 12 is pitched at an incline from the vertical wall portions 22 of the liner 12 toward a suitable drain opening 32 provided therein and connected through suitable plumbing means to drain the water from the pool, as desired.
Further, as shown in FIGURE 1, there is provided a water inlet fixture 33 which opens through the wall portion 22 of the liner 12 and is connected to suitable water supply means for filling the pool, while a water outlet skimmer fixture 35 of conventional type also projects through the wall portion 22 and is connected through suitable plumbing means to drain the water from the pool so as to maintain the water in the pool at a predetermined level.
A feature of the invention is the provision of the novel means for supporting the water filled pool liner 12 above ground level under pressure of the water, particularly in the assemblage of the bottom steel channel frame 16 of FIGURE 4 and the top steel channel frame 14 of FIG- URE 5, as hereinafter explained.
Assembly of pool structure On assembling the pool structure of FIGURE 1, a stake may be placed in the ground at each corner where the pool structure is to be placed. The ground is then scraped level in all directions in the staked out area. The steel channel bars for the bottom frame 16 are then placed as shown in FIGURE 4, on the scraped level area with U of the channel bars 40, 41, 42 and 43 laying with the open side up.
The drain pitch for the bottom 27 of the pool liner 12 may be effected by scraping the ground so as to pitch the level gradually from each of the four sides, making the depth approximately six inches lower at the center drain 32 while the bottom of the U channel bars will be about six inches above the center of the pool and thereafter placing sand within the confines of the bottom frame 16 so formed as to effectively pitch the level of the sand bottom from the sides to the pool drain 32, to the desired incline, as best shown in FIG. 3.
In assembling the bottom frame 16, a steel corner brace strap 45 is placed under the U channel bar at each corner, as shown in FIGURE 4, and suitably bolted at 47 and 49 to the end channel bars 4-1 or 43 and side channel bars 40 or :2, as the case may be, with high tensile bolts having hand tightening nuts on top. A steel bracing strap or straps 51 are placed under the side channel bars 4%} and 42 and bolted thereto by high tensile bolts 53 and 55.
The end channel bars 41 and 43 are now back fastened to the side channel bars 40 and 42 by a suitably flat steel fish plaate 48 fastened thereto by suitable high tensile bolts 50, having hand tightening nuts on top as best shown in detail in FIGURE 8.
The assembled bottom channel frame 16 is leveled and then the plywood panels 25, shown in FIGURES 1, 3 and 7, are set edgewise in the ground inside the bottom channel frame 16 and against the U channel bar of the frame 16 with the smooth side of the plywood panel 25 facing out.
A series of Wooden supporting posts 52 and 54, as shown in FIGURES 1 and 3, extend vertically from the channel bars of the bottom frame 16 with the lower ends of the posts 52 and 54 standing in the U channel of the bars of the bottom frame 16. The bottoms and tops of the supporting posts 52 and 54 are suitably chamfered, as indicated at 53 in FIGURE 3, to fit the channels of the U bar of the top frame 14 and bottom frame 16 so as to render full bearing surface for the plywood panels 25.
Care should be taken that the plywood panels 25 are flush with the bottom of the channel bars of the bottom frame 16, as shown in FIGURE 3. The plywood panel 25 is then secured by nails or suitable WOOd screws 57 to the posts 52 and 54.
Channel bars 60, 61, 62 and 63 of the upper channel bar frame 14 are next assembled on the top end of the supporting posts 52- and 54 with the U of the channel bars 60, 61, 62 and 62': of the upper frame 14, laying with the open side down on the top of the posts 52 and 54, as shown by FIGURE 3.
The end channel :bars 61 and 63 are set at right angles to the side channel bars 60 and 62 as shown in FIGURE 5, with the end channel bars being fastened to the side channel bars at the corners of the upper frame 14 by a suitable flat steel fish plate 68 fastened thereto by suitable high tensile bolts 70, as shown in detail by FIG- URE 6. The fish plate 68 is thus bolted to the top of the corner with the heads of the bolts 70 on top. All corners of the upper frame 14 are similarly connected.
Camber bars 75 and 77 are next fastened at opposite ends to the outer flanges of the U side channel bars 60 and 62, respectively, by bolts 7 9, as shown by FIGURES 5 and 6. The camber bars 75 and 77 are formed of hot rolled flat steel which is bowed, as shown in FIGURES 5 and 10, in relation to the U steel channel bars. The initial position of the camber bar '75 in relation to the U steel channel bar 66 is shown by solid lines in FIGURE 10.
Wooden camber blocks or wedging means 80A and 80B are inserted between the bowed camber bar 75 and the U steel channel bar 60 so that there is effected an approximate five degree inward bow or arch in the middle of the U steel channel bar 60, as shown by dotted lines in FIGURE 10.
Similarly wooden camber blocks or wedging means 82A and 82B are inserted between the bowed camber bar 77 and the U steel channel bar 62 so that there is effected a similar inward bow or arch of approximately five degrees in the middle of the U steel channel bar 62, as shown in FIGURES 5 and 10.
The camber bars 75 and 77 thus serve to flex or arch the steel channel bars 60 and 62 inwardly so as to provide a flexural top channel bar frame 14 of greater strength for supporting, in cooperative relation with the bottom channel bar frame 16, the pool liner 12 above the ground level and under pressure of the water carried within the liner 12, as will be hereinafter explained.
A steel angle bar 83, as shown by FIGURE 9, is then set vertically in each corner of the upper and lower channel bar frames 14 and 16 inside the respective frames and between the plywood walls 25 and the inside flange of the U channel bars of the upper and lower frames 14 and 16. It may be necessary to shift the existing plywood wall 25 to cause the inside corners of the plywood to just meet, while the vertical steel angle bar 83 is positioned so as to be flush to the upper edge of the top of the U channel bar of the upper frame 14, as shown by FIGURES 7 and 9.
The plywood panels 25 are nailed to the wooden supporting posts 52 and 54 before they are set in the steel corners of the frame structures, as shown by FIGURES 1 and 3. An important feature of the corner steel angle is that it prevents the adjacent corner of the plywood panel 25 and the liner 12 resting against it from moving out of position or bursting.
Each of the supporting posts 52 has fastened thereto a supporting beam 90 and a cross bar 92 to provide an outrigger means which, in turn, carries an outer deck joist 95 arranged in spaced relation to the inner deck joist 20 carried by the top channel frame 14 for supporting a pool deck.
The pool deck includes suitable planks 100 which are nailed to the joists 2t) and 95, while top posts 102, shown in FIGURE 1 and in detail in FIGURE 3, are each secured to the cross bar 92 of the outrigger means by suitable bolts 105 and to the back deck joist 95 by a second bolt 107.
The rail 110 is pre-slotted or dadoed to receive the top of the posts 102, thereby automatically aligning them vertically and making them structurally stronger.
When the tops of the posts 102 have been fitted within the dado slots, the top rail 109 and the rail 110 may be nailed together and to said posts. The sill or top rail 109 on the rail 110 are offset with respect of the joists 20, which provides a very important safety feature of reinforcing the superstructure or fence.
The fibre glass panel 115 may now be nailed to the posts 102 around the entire fence perimeter of the pool, as shown in FIGURE 1, with the rail 110 abutting the top edge of the fibre glass panel 115 while the bottom edge of the fibre glass panel 115 abuts an upper edge of a rail 117 fastened to a lower portion of each of the fence posts 102.
A pool entry ladder 124} provides a convenient access to the pool through an opening 125 in the pool fence, and the ladder 120 may be conveniently hinged so as to permit the same to be readily raised or lowered.
With the pool thus assembled a garden hose may be used to start the filling of the liner 12 with water. Should any small wrinkles appear in the liner 12, the same may be removed by gently pulling the liner 12. After the initial filling of the pool, further filling and draining of the pool may be effected by the conventional plumbing equipment heretofore described, including the water inlet fixture 33, pool drain 32 and the skimmer 35.
The assembled pool may be modified so as to include a sun deck 139, shown by dotted lines in FIGURES 1 and 2.
It will also be obvious that by making other appropriate modifications of the top and bottom channel frames 14 and 16, the pool may be constructed in many other shapes from the rectangular shape illustrated in the drawings. For example, the principles of the invention may easily and readily be incorporated in a pool of square shape, triangular shape, T-shape, U-shape as well as many other distinctive shapes.
The size and water capacity of the above ground pool embodying the principle of the invention are practically unlimited without danger of distortion or breakage of the liner 12 due to an improved construction of the supporting top and bottom channel frames 14 and 16, as shown by FIGURES l1 and 12, in which corresponding numerals indicate corresponding parts to those indicated and described with reference to FIGURES 3, 4 and 5. It will, of course, be obvious that as the size of the pool is increased the size of the channel frames, supporting posts, joists, etc. must be correspondingly increased in accordance with accepted standards for maintaining the same safety ratio.
In such improved construction, there is provided an improved rectangular bottom U channel bar frame 16 in which there is utilized a plurality of steel bracing straps 51A, 51B and 51C bolted to the underside of the channel bars 40 and 42 by high tensile bolts 53A, 53B and 53C and 55A, 55B and 55C, as shown by FIGURE 11.
Furthermore, arranged in cooperative relation with the bottom U channel bar frame 16 of FIGURE 11, there may be provided a corresponding rectangular improved top U channel bar frame 14, as shown by FIGURE 12.
In the improved frame 14, of FIGURE 12, there are provided the camber bars 75 and 77 fastened at opposite ends to the outer flanges of the side U channel bars 60 and 62 by high tensile bolts 79.
Wooden camber blocks 80A, 80B and 80C are inserted between the bowed camber bar 75 and the U steel channel bar 60 so that there is effected an inward bow or arch in the middle of the U steel channel bar 60 while similar Wooden camber blocks 82A, 82B and 82C are inserted between the bowed camber bar 77 and the U steel channel bar 62 so that there is effected a similar inward arch or bow in the middle of the U steel channel bar 62, as shown by FIGURE 12.
There are also provided camber bars 85 and 86 which, like the camber bars 75 and 77, are formed of hot rolled fiat steel and bowed, as shown in FIGURE 11, in relation to the end U steel channel bars 61 and 63, respectively, provided at the ends of the rectangular top frame 14. The camber bars 85 and 86 are fastened at opposite ends to the outer flanges of the U channel bars 61 and 63 by high tensile bolts 87.
A wooden camber block or serted between the bowed camber bar 85 and the U steel channel bar 61 so that there is effected an inward arch or how in the middle of the U steel channel bar 61. A similar wooden camber block or wedging means 89 is inesrted between the bowed camber bar 86 and the U steel channel bar 63 so that there is effected a similar inward bow or arch in the middle of the U steel channel bar 63.
The four U steel channel bars 60, 61, 62 and 63 of the top frame 14 are thereby arched or bowed inwardly under tension of the respective camber bars 75, 85, 77 and 86 so as to provide a substantial increase in the strength of the structural support provided for the liner 12 by the top frame 14 of FIGURE 12 in cooperation with the bottom frame 16 of FIGURE 11. Thus the water capacity of the liner 12 supported above ground level may be substantially increased without danger of distortion or bursting of the sidewalls of the assembled pool under the pressure of the water contained therein.
Although several embodiments of the invention have been illustrated and described, various changes in the form and relative arrangements of the parts, which will now appear to those skilled in the art, may be made without departing from the scope of the invention.
