Description
BRIEF DESCRIPTION OF THE INVENTION
The present invention relates generally to improvements in swimming
pools and, in particular, it relates to an improved swimming pool
which is assembled from prefabricated panels and frame members.
The use of above-ground swimming pools constructed from
prefabricated parts is becoming increasingly popular. However, the
problem of providing an above-ground pool which is easily
assembled, strong and durable, has continued to be a problem in
industry. It is, therefore, a primary object of the present
invention to provide an improved above-ground pool which is easy to
assembly, structurally sound, durable and designed in such a manner
that no reinforcing rods or straps pass across the inside bottom of
the pool. In addition, it is an object to provide a swimming pool
having an elevated deck extending entirely around the upper
periphery of the pool, which has decorative side panels to conceal
the filter system and pumps of the pool, as well as the outer
surfaces of the pool sidewalls. Roll-away steps are also utilized
in the pool of the present invention which can be stored and locked
in place under the deck when not in use so that small children
cannot gain access to the pool.
In accordance with the above objects, the rectangular swimming pool
of the present invention comprises four walls which are joined
together at right angles in such a manner as to assure maximum
strength. The corners of the pool are provided with corner cove
members to prevent water stagnation and the walls are made up of a
plurality of panels having integral channel or L shaped lower
portions, which overlie a block or concrete foundation. The channel
or L shaped portions maintain the lower portions of the walls in
position when internal pressures are exerted on the walls by water
within the pool and also provide a safety ledge around the
perimeter of the pool.
Extruded hanger elements, for anchoring the peripheral edges of the
pool liner in place, extend around the inner edge of the pool deck
and are secured by bolts to the deck and outwardly extending
flanges of the wall panels. Coping elements are provided which both
cover the hanger assembly and help retain the peripheral edge of
the liner on the extruded hanger elements.
The elevated deck, which is provided with leveling jacks, extends
around the upper peripheral edges of the pool, is supported by a
lower pool enclosure assembly and held down by adjustable torsion
cables which are connected to the deck structure so as to exert a
downward and inward force on the deck. The torsion cables are
anchored to the corners of the pool at their ends and passing
around the outer edges of deck frame members intermediate their
ends. The frame members extend along the joints of adjoining deck
panels or sections and are secured to the panels so that the forces
exerted on the frame members by the torsion cables are transmitted
to the deck.
The lower pool enclosure assembly has struts which not only support
the elevated deck, but also carry lower decorative panel assemblies
that hide the outer surface of the pool sidewalls, the pump and the
filter equipment utilized with the pool. Roll-away stairs are
provided at one end of the deck with the upper ends of the stairs
being mounted on tracks which extend beneath the deck so that the
stairs may be stored and locked in place under the deck when not in
use.
Other unique features and advantages of the present invention will
be more thoroughly understood from the following detailed

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIGS. 1 through 4, the swimming pool is generally
designated by reference character 20. The pool comprises sidewalls
22, 24, end walls 26, 28, a level or concave sand floor 30 or a
floor with a hopper 32 and an elevated deck 34 which extends
entirely around the tank of the pool.
The sidewalls 22, 24 and end walls 26, 28 of the pool are made up
of metallic panels 36 or 36' which, as best illustrated in FIGS. 4,
5 and 6, are mounted on a cinder block, cement or similar
foundation. In the preferred form of the invention, a trench about
the depth and width of a standard cinder block is dug around what
will be the inside perimeter of the pool side and end walls. When
the trench has been leveled, a cinder block or cement foundation 38
is placed therein and the wall panels 36 of the pool can be put in
place.
To anchor the wall panels 36, 36' to the cinder block or cement
foundation 38, the lower portion of each panel 36, 36' is provided
with an inwardly extending, downwardly opening, channel or L shaped
extension 40 or 40' which overlies the cinder block or cement
foundation.
As shown in FIG. 5, L shaped extension 40' comprises an
intermediate horizontal web 44' about the width of a cinder block
and a vertical 3-inch flange 46' extending downwardly from the
inner end of web 44'. Flange 46' engages the inner surface of
foundation 38 while the lower terminal portions of vertical channel
members 48 engage the outer surface of foundation 38. With this
arrangement, inner flange 46' maintains the lower portions of the
panels, and consequently, the sidewalls in a fixed position when
the sidewalls are subjected to internal pressure from water within
the pool. In addition, the L shaped extension 40' along with the
lower terminal portions of frame members 48 provide means for
properly aligning and positioning adjacent wall panels 36' of the
assembly. The panels 36' of sidewalls 22, 24, and end walls 26, 28
are bolted or otherwise secured to the webs of vertical channel
frame members 48 which extend along the joints formed by the
abutting or overlapping edges of the wall panels from the upper
edges of the panels to 3 inches below the juncture of terminal
extensions 40' with the upper vertical portions of panels 36'.
As shown in FIG. 6, the channel-shaped extension 40 comprises an
outer vertical flange 42, an intermediate horizontal web 44 about
the width of a cinder block and an inner vertical 3-inch flange 46.
The inner flange 46, which engages the inner surface of foundation
38, maintains the lower portions of the panels, and consequently,
the sidewalls in a fixed position when the sidewalls are subjected
to internal pressure from water within the pool. In addition, the
channel-shaped extension 49 provides means for properly aligning
and positioning adjacent panels of the assembly, The panels 36 of
the sidewalls 22, 24, and end walls 26, 28 are bolted or otherwise
secured to the webs of vertical channel frame members 48 which
extend along the joints formed by the abutting or overlapping edges
of the panels from extensions 40 to the upper edges of the
panels.
Horizontal braces 47 extend between adjacent channel frame members
48 along the outer surfaces of panels 36 or 36' to strengthen the
middle panels 36 or 36' of the side and end walls. Braces 47 are
not provided for the corner panels of the side and end walls where
the additional bracing is not needed. As shown in FIG. 4, which has
some of the braces 47 removed to better illustrate the
construction, and FIG. 5, the webs of horizontal braces 47 extend
beyond the flanges at each end of the brace to form tongues which
are received in slots 49 of channel frame members 48. During
assembly of the pool, one of the tongues is inserted in a slot 49
of a frame member 48 already secured to panels 36 or 36' and the
other end is inserted in the slot of an adjacent frame member 48
prior to securing the frame member 48 to the wall panels.
Pool sidewalls 22 and 24 extend perpendicular to pool end walls 26
and 28 with the tank of the pool thereby being rectangular in
horizontal cross section. The rectangular configuration of the pool
with the resulting right angle corner joints, FIG. 9, enables the
pool corners to be constructed so as to provide for maximum
strength. The corner panels at each of the corner joints are bolted
to vertical angle or W shaped support frame members 50 or similar
angle members which lend great strength and rigidity to the pool
structure. While this construction is very strong and durable, it
is not desirable to have a pool with right angle corners since the
water within the pool tends to stagnate in such corners resulting
in an accumulation of dirt. To eliminate stagnant water and dirt
accumulation in the sharp corners and to reduce burbling of the
water circulation, thereby improving filtration, corner cove panels
52 are provided at each corner of the pool. The corner cove panels
52 extend from channel or L shaped extensions 40, 40' which are
mitered at the corners to insure a proper fit, to the upper edges
of the wall panels 36, 36'. The inner surfaces of panels 52 are
generally smooth and concave thereby rounding out the corners of
the pool so that there are no places for the water within the pool
to stagnate. These panels 52 are bolted or otherwise secured to
corner panels 36, 36' and as can be readily appreciated, not only
improve the circulation of water within the pool, but also provide
an aesthetically pleasing appearance.
The sidewalls 22 and 24 of the pool are provided with external
torsion cables 54, 56, respectively, which hold the deck panels or
sections in and down. As best shown in FIGS. 4, 7 and 8, the cables
are secured at each end of the vertical corner support frame
members 50 at points spaced below the upper edges of the pool walls
by means of brackets 58, 58', which are bolted, welded or otherwise
secured to the corner frame members. The brackets 58, 58' are made
up of legs 60, 60' and 62, 62', which extend perpen-dicular with
respect to each other, and diagonal extensions 64, 64' that diverge
outwardly from the pool sidewall and which are integral with legs
62, 62'. The cables 54 and 56 are mounted on the brackets by means
of cable clevis or yokes 66 having pins which pass through
apertures in the diagonal extensions 64, 64' of the brackets. Turn
buckles 67 and 67' are provided in each cable so that the tension
in the cable can be adjusted as necessitated.
Center deck and cable support struts 68 and 70 are positioned
midway along the upper edges of sidewalls 22 and 24, respectively,
and extend perpendicular to the sidewalls 22, 24 in a generally
horizontal plane. The struts are bolted to the undersides adjacent
deck panel sections with the struts extending along the joints
formed by the middle deck panel sections of sides 22, 24. The inner
ends of struts 68 and 70 do not abut frame members 48 and the outer
ends are engaged by the torsion cables 54 and 56. In the preferred
form of the invention, a horizontally extending notch 71 is
provided in the outer edge of each center deck and cable support
strut within which is mounted tube 72 or some similar element which
prevents the torsion cable from chafing.
As can be readily seen from FIGS. 4 and 7, the center deck and
cable support struts 68 and 70 are mounted on the undersides of
abutting deck panels of the swimming pool at a greater height than
the ends of the torsion cables 54 and 56 which are secured to the
brackets at the corners of the pool. As a result of this assembly,
the lines of force acting on the center deck and cable support
struts 68 and 70 not only are directed inwardly, but also
downwardly so that the cables help to hold deck 34 in and down.
FIGS. 17 and 18 are diagrammatic views illustrating modifications
of the torsion cable assembly to be utilized on pools of greater
width and length than the one illustrated in FIGS. 1 to 4. FIG. 17
illustrates a pool which is of such a width that torsion cable
assemblies 200, 200', similar to those illustrated in FIGS. 7 and
8, are required along the ends of the pool as well as the sides.
The brackets 202, struts 204 and cables 206 utilized in the
assembly of FIG. 17 can be the same as those of FIGS. 7 and 8 or,
if desired, along the end of the pool having the wide deck, the
cables can be secured to the cable support struts at points spaced
inwardly from the outer end of the struts. FIG. 18 illustrates a
second modification of the torsion cable assembly for use on a pool
of greater width and length than the pool illustrated in FIGS. 1 to
4. The torsion cable assemblies along the ends of the pool are the
same as those illustrated in FIG. 17. However, due to the length of
the pool, torsion cable assemblies 208, 210 and 212 are not only
secured on each side of the pool to the center deck and cable
support strut 214, but also deck and cable support struts 216, 218
on either side of the center deck and cable support strut. Support
struts 216, 218 are secured to deck at the joints between the
middle panel sections 220, 222 and panel sections 224, 226
respectively, while strut 214 is secured to the deck at the joint
between the middle panel sections in the same manner that struts 68
and 70 are joined to the deck 34. With the above arrangement, the
outer edges of a pool deck of great length and width can be
securely held down and in place.
The floor of the pool can be flat, level or concave as shown by
floor 30 in FIG. 4, or, as shown in FIGS. 1 to 3, the pool can be
provided with a hopper at one end which extends below the surface
of the ground. When it is desired to have a pool with a flat, level
or concave floor such as 30, a flexible liner 73 of water-proof
material is laid over sand or suitable fill enclosed by the
sidewalls and end walls of the pool and the liner is secured to
hangers on deck 34 and adjacent the upper edges of sidewalls 22, 24
and end walls 26, 28 as will be fully explained hereinafter. Of
course, a suitable drain can be provided in the floor of the pool
which, in combination with outlet 74 in end wall 26, connects the
tank of the pool with the conventional pump and filtration system
75.
When it is desired to construct a pool with a hopper, a tubular
frame assembly 32, such as the one shown in FIGS. 2 and 3, is
utilized. Frame assembly 32 is laid within an excavation at one end
of the pool and is made up of a lower square center framework 76, a
larger upper square framework 78 and connecting members 80 which
extend from the corners of framework 76 upwardly and outwardly to
the corners of framework 78. The tubular frame members of the
assembly are bolted, welded or otherwise secured to each other
along their abutting edges. As in the embodiment utilizing a flat,
level or concave floor, the interior of the pool is lined with a
flexible liner 73 of water-proof material. The liner is laid over
sand or other suitable fill at the shallow end of the pool and over
the tubular frame assembly 32 at the deep end of the pool with the
liner being so shaped as to conform to the contours of the tubular
frame assembly 32. As in the previous embodiment, a drain 81 can be
provided in the liner which is mounted on strap 82 extending
between tubular frame members of lower framework 76.
As best shown in FIGS. 6 and 14, the peripheral edges of liner 73
is heat sealed or otherwise secured to vertical extensions 83 of
extruded vinyl hooks 84. Hooks 84 are retained on hangers 85 which
extend around the inner edge of deck 34. Hangers 85 are preferably
made of extruded aluminum members and comprise base portions 86
that are secured to deck 34 by bolts which pass through deck panels
94 and into nuts mounted in upper flanges 100 of the vertical wall
panels 36 or 36'. Hanger members 85 have vertical web portions 87
extending upwardly from the inner ends of base portions 86 and
horizontal flanges 88 which extend outwardly from the upper end of
web 87 to form hooks which retain hooks 84 of liner 73.
An extruded vinyl coping 89 is provided to cover the hanger
assembly and help retain the complementary hooks of the hanger
assembly (members 84, 85) in place. Coping 89 has a hollow section
90 with a convex inner surface that extends below extensions 83 to
cover the upper edges of the liner 73 and give the inner rim of the
pool an aesthetically pleasing appearance. Hook portion 91 extends
outwardly from the upper end of hollow section 90 and when the
coping 89 is in place, FIG. 14, hook portion 91 overlies hook 84
and is retained on hangers 85. A resilient extension 92, which, as
shown in FIG. 15, is normally curved, merges with hook portion 91.
Extension 92 covers the outer ends of hangers 85 and due to its
resilience, maintains hook portion 91 on hanger 85 thereby insuring
that the coping 89 is firmly anchored in place.
The elevated deck 34, which extends around the upper edge of the
swimming pool tank, is approximately 2 feet wide along sidewalls
22, 24 and end wall 28 and 6 feet wide along end wall 26. As shown
in FIGS. 6 and 10, the deck comprises a series of plywood panels 94
which have complementary alignment dowels 96 and apertures 98 along
their abutting edges; while the outer edges of the panels have
molding strips 99 secured thereto which hide horizontal deck frame
members 102 and strengthen the outer perimeter of the deck. The
inner edges of panels 94 extend along and are supported by the
upper flanges 100 of the vertical wall panels 36. The bottom
surfaces of panels 94, adjacent their abutting edges, have wood
nuts 104 mounted therein that are aligned with apertures in the
horizontal deck frame members 102 which extend part of the way
along the joints of the deck panels 94 from the outer edge of the
deck to points spaced from the side or end walls. Bolts passing up
through the webs of the channel-shaped horizontal deck frame
members rigidly secure the deck 34 to these members. In addition, a
series of holes are provided in panels 94, which are aligned with
apertures in the upper wall flanges 100 of the vertical sidewall
panels 36 so that the inner ends of the deck panels can be rigidly
secured to the side and end walls by the same bolts which secure
hangers 85 to the deck. With the use of coping 89 around the inner
perimeter of the deck along with wood nuts 104, the deck has a
smooth upper surface completely free of obstructions.
The outer edge of deck 34 along sidewalls 22, 24 and end wall 28 is
supported by diagonally extending frame members 106. Members 106
are bolted, pinned or otherwise secured at their lower ends to the
vertical frame members 48 adjacent the lower ends of the vertical
frame members and have plates 108 welded to or fabricated as part
of the upper ends of the diagonal frame members 106. As best shown
in FIG. 16, plates 108 are secured to the outer edges of the deck
panels 94 by jack assemblies 150. Jack assemblies 150 comprise
studs 152, railing base members 154, plates 108, nuts 156, 158, 160
and plates 162 or extensions of the webs of frame members 68, 70 or
102 when the jack is located at a joint between deck panels 94. The
heads of studs 152 are mounted within railing base members 154 and
extend downwardly through apertures in panels 94, plates 162 or the
web extensions and plates 108. Nuts 156 are tightened against
plates 162 or the web extensions to rigidly secure the base members
154 and plates 162 or web extensions as well as studs 152 to the
deck. Nuts 158 and 160 engage the upper and lower surfaces of plate
108 so that by loosening and tightening nuts 158, 160, the level of
the outer edges of deck 34 along sides 22, 24 and end 28 can be
adjusted.
Unlike the diagonal support frame members 106 along sides 22, 24
and end 28, no jack assemblies interconnect the upper ends of
diagonal support frame members 112 to the deck along end 26 of the
pool. Instead plates 114 of the diagonal frame members are rigidly
secured to the deck in a fixed position by studs passing down from
railing base members 154. Diagonal support frame members 112,
instead of extending from the lower end of the vertical end wall
frame members 48, extend upwardly from and are bolted to
1-inch-diameter extension tubes 116 which are, in turn, secured at
their inner ends to the lower portions of vertical wall support
frame members 48. These extension tubes are, in turn, linked
together by a series of frame members 118 which run parallel to end
wall 26.
As shown in FIG. 11, the outer ends of extension tubes 116 are
provided with deck leveling jack assemblies 120 which each comprise
a stud 122 that is mounted on a plate 124 and passes through a pair
of apertures in one of the extension tubes 116. Nuts 126 are
provided on either side of the extension tube 116 so that by
loosening and tightening the nuts 126, the level of the outer ends
of extension tubes 116 can be altered, thereby altering the
elevation of the outer edge of the deck.
As shown in FIGS. 11 and 12, the diagonal support frame members
108, 114 are preferably made from either H shaped frame members or
T shaped frame members. These frame members 108, 114 not only
support the elevated deck, but also carry decorative panels 128
which extend from the lower ends of frame members 108, 114 to the
upper ends of these members to give the outside of the pool an
aesthetically pleasing appearance. These panels 128, which are
preferably either the coiled type, awning type or narrow panel
type, are made of plastic, aluminum, wood or similar materials and
are slid into position between adjacent diagonal deck frame
members.
When using the H shaped frame members, the decorative panels are
maintained in place between the pairs of flanges 130, 130' on each
side of the web so that there is no need for using screws, bolts or
other types of fasteners to keep the panels in place. In the
preferred form of the invention, approximately 6 inches of the rear
flange 130' of the H member is cut away at the top to permit the
panels 128 to be slid into place. However, it is contemplated that
the amount of flange 130' which is cut away can be varied as
required by the type of decorative panel used.
When a T shaped frame member is utilized, the lateral edges of the
outer surfaces of the decorative panels 128 rest on flanges 132;
while the inner surfaces of the decorative panels adjacent their
lower and upper edges engage vertical sidewall frame members 48
and/or a stop means 133 on extensions 116 and horizontally
extending plates 108 or 114, respectively, which thereby maintain
the decorative panels 128 in place.
Roll-away stairs 134 (FIG. 13) are mounted at one end of the pool
to provide access to and from the deck 34. The upper end of the
stairs are provided with a pair of outwardly extending roller 136
which are received in spaced-apart roller tracks 138 mounted on the
underside of the deck and secured by bolts or similar means to the
flanges of two of the horizontal deck support members 102. The
spaced-apart pair of tracks 138 extend parallel with regard to each
other from the outer edge of the deck to points adjacent the
vertical end wall 26 and are provided with stops or protrusions 140
at the inner and outer ends to keep the rollers 136 of ladder 134
from rolling off the tracks. While in the preferred form, the
tracks 138 are generally C shaped with each track having a slot
extending longitudinally along one side through which the support
axles for rollers 136 pass, it is contemplated that tracks 138 can
be of any suitable cross-sectional configuration. With this
arrangement, the stairs can be stored (as shown in dashed lines in
FIG. 2) under deck 34 simply by raising the lower end of the stairs
and pushing the stairs inwardly until rollers 136 engage the inner
stops 140. Apertures 141 can be provided in one of the tracks so
that a lock, similar to a bicycle lock, can be utilized to prevent
the stairs from being pulled out of storage by unauthorized
persons.
For the safety of those using pool 20, the pool has a railing 142
that extends entirely around and is secured to the outer perimeter
of deck 34. The railing has a gate 144 directly above stairs 134
and, as discussed above, base members of the railing form an
integral part of the deck leveling assemblies along sides 22, 24
and end 28.
While the preferred form of the invention has been shown and
described, it is to be understood that all suitable modifications
and equivalents may be resorted to which fall within the scope of
the invention as claimed.
