SWIMMING POOLS AND METHOD OF CONSTRUCTING THE SAME Allan Gordon Lorimer, Douglaston, N. Y., assignor to Malcolm A. Vendig, Sands Point, N. Y.
Application April 14, 1955, Serial No. 501,352 7 Claims. (Cl. 4172) The present invention relates to swimming pools, and more particularly to outdoor swimming pools for private or family use.
The construction of outdoor swimming pools for private or family use has heretofore been greatly restricted on account of the cost. By use of the present invention, pools can be placed wherever there is suflicient land area. A relatively shallow excavation will provide back fill to hold the pool structure in place.
In carrying out the present invention, an excavation of the desired size and vertical contour is made in the ground. A wall made of prefabricated panels of reinforced concrete or other suitable material of proper size is assembled on the site, a waterproof liner of proper shape is placed inside the walls, and a prefabricated, sectionalized coping of proper size is placed on top of the wall and rim of the liner. The coping is held in place by a tie cable. Back fill outside the wall panels holds the panels against spreading. The contour of the pool is preferably inwardly concave to provide a continuous arch to resist external pressure.
The accompanying drawings show, for purposes of il lustrating the present invention, one embodiment in which the invention may take form, it being understood that the drawings are illustrative of the invention rather than limiting the same.
In these drawings:
Figure 1 is a top plan view of the swimming pool;
Figure 2 is a longitudinal vertical section on the line 2-2 of Figure 1;
Figure 3 is a fragmentary side view showing a tightening cable and turnbuckle;
Figure 4 is an enlarged fragmentary sectional view on the line 2-2 of Figure 1;
Figure 5 is a still further enlarged sectional view on the line 22 of Figure 1;
Figure 6 is a horizontal, sectional view on a plane indicated at 6-6 in Figure 4; and
Figure 7 is a transverse view on the line 7-7 of Figure 1.
While the side walls of the swimming pool may be placed entirely above the existing grade of the ground, it is usually preferable to make an excavation for a part or all of the depth of the pool. In Figures 2 and 7, an existing grade is indicated by the dotted line 10-10. The complete excavation may be made initially or a ditch dug Where the peripheral walls of the pool are to be placed. The bottom is carefully leveled where the wall is to be placed.
The peripheral wall of the pool is made up of a. number of panel units 20 of metal, reinforced concrete or plastic, of suitable height, width and contour. As shown in Figures 4 and 6 these panel units have a substantially vertical; inwardly concave inner wall 21, a relatively wide bottom flange 22, a narrow top flange 23 and side flanges 2424. These side flanges are provided with holes to receive rust resistant tie-bolts 25 and spring lock washers 25. The vertical height of the panels is such as to provide a pool of suitable depth, for example, 3 feet at the shallow end. The lock washers allow limited expansion of the tank under excessive pressure.
The panel units are preformed and of shapes when assembled to form portions of cylinders. At the large diameter end of the pool such sections are assembled about an arc of as indicated at the left of Figure 1. Panel units for the narrow or right hand end of the pool will be constructed to form a cylindrical arc of shorter radius and less angle, as indicated at 26, Figure 1. The sides of the pool employ similar panels 27, but of much greater radius of curvature. Thus the assembly of panels presents the continuous arched construction well adapted to resist external forces.
A suitable pool 36 long, 22'6 wide may employ thirteen panels at the large end, five panels at the short end, and eight panels on each side.
After the side panels have been secured together to give the pool its general form and shape the excavation is completed to give the pool bottom the desired contour. The preferable contour is indicated in. Figures 2 and 7. Here the pool has a relatively shallow portion at the right and a deeper portion at the left. The bottom ofthe pool is very carefully prepared by the use of suitable templates which relate the bottom of the pool to the upper edge of the assembled side panels.
' Back fill indicated at 31 is placed outside the assembled panels. This is solidly packed back of these panels and in the cells formed by the flanges so that the assembled structure is thoroughly protected against spreading due to internal pressures.
After the panels have been arranged in place and the excavation made of the desired contour, a plastic liner 32, preferably made of heavy gauge vinyl sheet, is placedinto the pool. This liner is made accurately to size so that it fits the bottom of the pool, and the inner faces of the panels, and extends outwardly about the upper flanges of the side panels, as indicated at 33, Figures 4 and 5.
Coping blocks dicated at 41 are side walls. liner. centered about the same centers as the panels on which they rest and preferably of greater angular width. They are arranged as shown in the drawing to slightly overhang the side panels both inside and outside. These blocks have external grooves 43 adapted to receive a cable 44. The cable extends to the coping blocks and one of the blocks, such as the one at the left of Figure l, and shown in detail in Figure 3, has an enlarged cutout or notch 45, to accommodate cable clamps 46 whereby the cable may be tightened.
In ordinary use the swimming pool will be filled with water up to the top of the plastic liner. Usual pool accessories, such as ladders, diving stands and recirculating sys- 40 with downwardly facing channels inplaced on top of the flanges 23 and the Gaskets 42 protect the rim portion 33 of the terns may be employed if desired. The pool is preferably kept filled during the winter as this causes no damage to the liner or change in the contour of the bottom of the pool. The pool may also be used as a skating rink. When so used it is preferable to fill it up with water to a level abovethe top of the plastic liner so as to protect the liner against injury.
Since it is obvious that the invention may be embodied in other forms and constructions within the scope of the claims, I wish it to be understood that the particular form shown is but one of these forms, and various modifications and changes being possible, I do not otherwise limit myself in any way with respect thereto.
What is claimed is:
1. An outdoor swimming pool having an earth bottom,
a plurality of panels extending upwardly from said bot- These coping blocks are short annular sections tom at the periphery thereof and disposed side by side to form anenclosing wall, an earth embankment'outside the wall to resist outward displacement of said wall, a water tight liner fitting said enclosing wall and bottom and extending outwardly over the tops of the sidewall panels, and coping units forming a continuous coping covering the outwardly extending portion of the liner, said coping units having downwardly opening channels to fit about the tops of the side panels, and having a tie cable about the coping units to hold them in place.
2.
