Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to above-the ground, flexible plastic, inflatable-type swimming pools. More specifically, the present invention relates to methods and apparatus for a children's wading pool having a multiple-tier, inflatable sidewall and a bottom wall and includes a sun shade canopy that covers the pool and is supported by a pair of inflatable arched tubes which are attachable to and removable from the top of the wading pool by hook and loop fastener means.




2. Description of the Prior Art




The prior art is directed to methods and apparatus for above-the-ground inflatable swimming or wading pools typically fashioned from polyvinylchloride sheeting, having a sun blocking canopy, and used in the out-of-doors.




Swimming and wading pools intended for use by children and comprised of inflatable plastic materials such as polyvinylchloride (hereinafter “PVC”) sheeting and having a multiple-tier inflatable sidewall including appropriate air valves and a plastic bottom wall are known in the art. These swimming and wading pools are intended to hold a minimum amount of water to enable one or more small children to play therein and splash the water on warm days.




Likewise, devices intended to shade people from the direct rays of the sun are also known in the art. For example, several aquatic lounge and floatation devices have been known. These devices do not themselves contain water, i.e., they are not a swimming or wading pool, but are designed to float within a larger body of water such as a swimming pool, pond, lake and the like. For example, one known device is an aquatic lounge having a pair of generally parallel, spaced-apart longitudinally extending buoyant members intended to float in a swimming pool or the like. The aquatic lounge includes a head rest having a small canopy for shading the face of an individual resting on the lounge. The shade canopy is removable from the head rest via a plurality of threaded mechanical fasteners. The aquatic lounge also includes a serving tray attachment having a small canopy positioned thereover for protecting, for example, soft drinks from direct sun light on warm days.




Another known device is a recreational floating apparatus typically used by small children with the assistance of an adult. This device is also an aquatic floatation mechanism which includes a circular foamed plastic float, a supporting fabric seat and an attached frame collapsible canopy. The supporting seat is adapted to support a small child or infant in an upright position. The collapsible canopy is adapted to partially cover the occupant of the floating apparatus to provide protection from the sun. A third known device includes a similar floatation device which can serve as a seat and includes an umbrella shade mechanism positioned directly over the floatation portion of the device. Yet another similar device discloses an umbrella support for attachment to a recreation floatation device such as a large intertube equipped with seats. The umbrella support includes a socket for mounting the support shaft of a sun shade umbrella therein.




Another device is characterized by an inflatable raft-like floatation device for use in, for example, a swimming pool. The raft-like device includes a series of communicating compartments wherein an outermost compartment pair is extendedly formed into a sun shade support. A sun shade having a fixed portion and an adjustable portion is affixed to the sun shade support. Another known device discloses a floating sun shield which has a rectangular floating frame and an arched sun shield canopy mounted over the rectangular floating frame. The floating frame can be comprised of polyvinylchloride and the sun shield canopy can be preferably formed of nylon fabric or similar materials. The arched portion of the canopy can include structural support rods. Many other sun shade type devices are also known in the art and are used typically with, for example, lounge chairs or the like. These sun shade type devices are also removable and replaceable but only via mechanical attachment means.




Thus, there is a need in the art for a children's wading or swimming pool having a multiple-tier, inflatable sidewall and a bottom wall, and where the swimming pool also includes a sun shade canopy where the canopy is supported by a pair of inflatable arched tubes and is quickly attachable to and removable from the top surface of the wading pool by hook and loop fasteners.




SUMMARY OF THE INVENTION




Briefly, and in general terms, the present invention provides a new and improved sun shade pool and method therefore typically used by small children as an above-the-ground wading pool. The sun shade pool includes an inflatable pool and a removable sun shade canopy mounted upon the inflatable pool for blocking direct sun light on warm days. The inflatable pool can be multiple-tiered in height, include a bottom wall and be fashioned from polyvinylchloride sheeting, include a plurality of inflation air valves for inflating the pool and a drain plug for rapidly draining water from the pool.




In a preferred embodiment, the removable shade canopy is attachable to and detachable from a top surface of the inflatable pool by a plurality of hook and loop fasteners. The sun shade canopy is formed from a pair of inflatable arched tubes and a sun blocking fabric suspended therebetween. Each of the inflatable arched tubes are generally identical in form, are separated by a pair of inflatable cross members which provide structural support, include an inflation air valve, and are inflated into a generally U-shaped tubular arch. The pair of inflatable arched tubes are mounted on opposite sides of the top surface of the inflatable pool. The sun blocking fabric is suspended between the inflatable arched tubes and over the inflatable cross members by attaching the fabric to each of the arched tubes by a known method such as by the use of radio frequency sealing or an adhesive. The inflatable arched tubes, inflatable cross members, and the sun blocking fabric can also be comprised of polyvinylchloride sheeting. However, the sun blocking fabric can also be formed of other known natural materials.




In the present invention, the sun shade canopy is attachable to and detachable from the inflatable pool by a plurality of hook and loop fasteners. The inflatable pool is typically rectangular in shape but is not limited to that geometric form. The top surface of a rectangular-shaped inflatable pool includes four corners. Each hook and loop fastener includes a hook portion and a loop portion. One suitable method of attachment and detachment of the sun shade canopy to the inflatable pool is to affix a hook portion of a hook and loop fastener to each of the two bottom ends of each of the pair of inflatable arched tubes. Likewise, the loop portions of the corresponding hook and loop fasteners are affixed to the top surface of the inflatable pool at each of the four corners. This design layout ensures that the hook portions will intersect with the corresponding loop portions and enables the sun shade canopy to be conveniently attached to and removed from the top surface of the inflatable pool.




The present invention is generally directed to a sun shade pool and method therefore typically used by children in an above-the-ground environment for use in the out-of-doors. The inventive sun shade pool provides an attractive and economic solution to parents with small children who seek relief from hot weather during the warm months of the year. The sun shade pool including the shade canopy enables the small child to enjoy the fun associated with splashing in water but simultaneously be protected from direct sun rays. Further, the sun shade pool provides these features without the necessity of the child being in the vicinity of a conventional swimming pool. In its most fundamental embodiment, the sun shade pool exhibits a construction including an inflatable pool having a sidewall sealed to a bottom wall for containing a fluid. A removable sun shade canopy for covering a top surface of the inflatable pool is also included. The canopy includes a pair of inflatable arched tubes attachably and detachably mounted to the top surface of the inflatable pool by a plurality of hook and loop fasteners. A sun blocking fabric is also suspended between the pair of inflatable arched tubes.




These and other objects and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings which illustrate the invention, by way of example.

DESCRIPTION OF THE INVENTION




The present invention is a sun shade pool


100


typically used by children in an above-the-ground environment for use in the out-of-doors. The sun shade pool


100


includes an inflatable pool


102


and a removable sun shade canopy


104


as shown best in

FIG. 1

but also in

FIGS. 2-5

. The inflatable pool


102


includes a continuous sidewall


106


comprising one or more vertical tiers. In the preferred embodiment, the continuous sidewall


106


includes two vertical tiers


108


,


110


, each comprised of a flexible inflatable material such as, for example, polyvinylchloride sheeting (typically referred to as PVC).




The vertical tiers


108


and


110


are independent air chambers and are fused together by means known in the art such as, for example, radio frequency sealing. Since each of the two vertical tiers


108


,


110


are independent air chambers, each includes an inflation air valve


112


as shown in

FIG. 3

for the insertion and discharge of pressurized air. It follows that the gauge thickness of the polyvinylchloride sheeting of the vertical tiers


108


,


110


is suitable for the air pressure with which the vertical tiers


108


,


110


are charged. Since each of the vertical tiers


108


and


110


are charged with pressurized air, each of a plurality of side surfaces


114


are rounded as shown with the appropriate shading in

FIGS. 1-5

,


10


and


11


.




The upper vertical tier


110


of the continuous sidewall


106


has a top surface


116


which is continuous with the side surfaces


114


of the vertical tiers


108


and


110


. The top surface


116


of the vertical tier


110


and the rounded side surfaces


114


of the vertical tiers


108


and


110


are more clearly shown in the cross-sectional view of FIG.


10


. It is the top surface


116


of the upper vertical tier


110


of the continuous sidewall


106


that supports the sun shade canopy


104


as will be discussed more fully hereinbelow with regard to

FIGS. 6 and 11

enclosed herewith.




The inflatable pool


102


also includes a bottom wall


118


as best shown in

FIGS. 7 and 8

but is also partially shown in FIG.


1


. The bottom wall


118


is also preferable comprised of polyvinylchloride sheeting but can be of a lower gauge thickness than the vertical tiers


108


and


110


. The bottom wall


118


, which serves as a floor surface, can be of a lower gauge thickness since it is not exposed to pressurized air. Thus, the gauge thickness of the bottom wall


118


is suitably selected for its intended use. The bottom wall


118


is sealed to the lower vertical tier


108


of the continuous sidewall


106


along a sealing line


120


as is best shown in FIG.


7


. The sealing line


120


is not visible in the top planar view of the inflatable pool


102


shown in

FIG. 8

because of the overhang of the top surface


116


. The sealing or fusing of the bottom wall


118


to the vertical tier


108


is accomplished in a manner known in the art such as, for example, radio frequency sealing or adhesive sealing.




Thus, the polyvinylchloride sheeting of the bottom wall


118


is sealed or fused to the polyvinylchloride sheeting of the vertical tier


108


along sealing line


120


to complete the construction of the inflatable pool


102


. The completed inflatable pool


102


is then capable of containing a fluid such as water which can be introduced into the inflatable pool


102


with, for example, a garden hose. Located within the polyvinylchloride sheeting of the bottom wall


118


is a drain plug


122


. The drain plug


122


can be of, for example, a flexible or semi-rigid polyvinylchloride construction as is known in the art. The drain plug


122


typically includes a base flange


124


(see

FIG. 8

) which is fused as by radio frequency sealing to the polyvinylchloride sheeting about the perimeter of a penetration (not shown) formed in the bottom wall


118


. The discharge end of the drain plug


122


passes through the penetration (not shown) and serves as an exit point for the water when the drain plug


122


is in the open position as is shown in FIG.


7


.




The sun shade canopy


104


comprises three main components including a pair of inflatable arched tubes, i.e., a first inflatable arched tube


126


and a second inflatable arched tube


128


, and a sun blocking fabric


130


. Each of the inflatable arched tubes


126


and


128


and the sun blocking fabric


130


are shown in

FIGS. 1

,


4


,


5


and


6


. Additionally, a pair of inflatable cross members, i.e., a first inflatable cross member


132


and a second inflatable cross member


134


are incorporated into the sun shade canopy


104


as shown in FIG.


9


. The sun shade canopy


104


is attachable to and detachable from the inflatable pool


102


by a plurality of hook and loop fasteners


136


as is shown in

FIGS. 1 and 11

. It is noted that the entire interior volume of the inflatable pool


102


including the top surface


116


is covered by the sun shade canopy


104


as shown in FIG.


1


. Thus, a child seated at any location within the interior of the inflatable pool


102


will be shaded from damaging sun rays during those hours of the day when the sun is directly above.




The first inflatable arched tube


126


and the second inflatable arched tube


128


serve to hold the sun blocking fabric


130


over the inflatable pool


102


. The pair of inflatable arched tubes


126


and


128


are separated and structurally reinforced by the first inflatable cross member


132


and the second inflatable cross member


134


as is clearly shown in FIG.


9


. Each of the inflatable arched tubes


126


and


128


are essentially identical in construction and form and are comprised of a robust flexible plastic such as, for example, polyvinylchloride sheeting. Each of the pair of inflatable arched tubes


126


and


128


include an inflation air valve


138


as known in the art for the insertion and discharge of pressurized air as is best shown in FIG.


1


. Once inflated, the first and second inflatable arched tubes


126


and


128


adopt a generally U-shaped tubular arch form and are parallel mounted on opposite sides of the top surface


116


of the inflatable pool


102


. The first and second inflatable arched tubes


126


and


128


are independent air chambers.




The first inflatable cross member


132


and the second inflatable cross member


134


are parallel positioned between and orthogonal to the first inflatable arched tube


126


and the second inflatable arched tube


128


as is shown in FIG.


9


. The first and second inflatable cross members


132


and


134


are generally identical in shape and are typically straight, tubular-shaped independent air chambers. Each of the first and second inflatable cross members


132


and


134


include an inflation air valve


140


as known in the art for the insertion and discharge of pressurized air as is shown in FIG.


9


. The first and second inflatable cross members


132


and


134


are sealed or fused to the first and second inflatable arched tubes


126


and


128


by means known in the art such as, for example, radio frequency sealing or adhesive sealing. The first and second inflatable cross members


132


and


134


once fused to the first and second inflatable arched tubes


126


and


128


form a stable structure.




The sun blocking fabric


130


serves to block the direct rays of the sun to protect the children playing in the inflatable pool


102


. In the present invention, the sun blocking fabric


130


is suspended between the first and second inflatable arched tubes


126


and


128


as shown in FIG.


1


. Likewise, the sun blocking fabric


130


is positioned over the first and second inflatable cross members


132


and


134


as shown in FIG.


9


. Suspension of the sun shade fabric


130


between the first and second inflatable arched tubes


126


and


128


is accomplished by attaching the fabric


130


to each of the arched tubes


126


and


128


by a known method such as by the use of radio frequency sealing or adhesive sealing. Like the first and second inflatable arched tubes


126


and


128


and the first and second inflatable cross members


132


and


134


, the sun blocking fabric


130


can also be comprised of polyvinylchloride sheeting. However, the sun blocking fabric


130


can also be formed of any one of a plurality of woven fabrics such as cotton.




In the present invention, the sun shade canopy


104


is attachable to and detachable from the inflatable pool


102


by a plurality of hook and loop fasteners


136


best shown in

FIGS. 8

,


9


and


11


. The inflatable pool


102


is typically rectangular in shape but can adopt any geometric form. The top surface


116


of the rectangular-shaped inflatable pool


102


shown in

FIG. 8

includes a plurality of four identical corners


142


. Each hook and loop fastener


136


includes a hook portion


144


and a loop portion


146


. One suitable method of attachment and detachment of the sun shade canopy


130


to the inflatable pool


102


is to affix as by gluing a hook portion


144


of a hook and loop fastener


136


to each of the two bottom ends


148


of each of the first and second inflatable arched tubes


126


and


128


. Likewise, the loop portions


146


of the corresponding hook and loop fasteners


136


are affixed as by gluing to the top surface


116


of the inflatable pool


102


at each of the four identical corners


142


. This design layout ensures that the hook portions


144


of the hook and loop fasteners


136


will intersect with the corresponding loop portions


146


and enable the sun shade canopy


104


to be conveniently attached to and removed from the top surface


116


of the inflatable pool


102


.




The present invention provides novel advantages over other inflatable pools for use by small children known in the prior art. A main advantage of the sun shade pool


100


of the present invention is that the sun shade canopy


104


is removable, i.e., it is attachable to and detachable from the top surface


116


of the inflatable pool


102


. This feature is helpful in transporting and storing the sun shade pool


100


. Further, the sun shade canopy


104


is held in position by the pair of inflatable arched tubes


126


and


128


that utilize hook and loop fasteners


136


to attach to and detach from the inflatable pool


102


. Thus, conventional mechanical attachment means are avoided. Additionally, the sun shade canopy


104


including the pair of support inflatable cross members


132


and


134


and the sun blocking fabric


130


cover the entire surface area of the inflatable pool


102


. Consequently, the inventive sun shade pool


100


enables small children to obtain relief from hot weather and to enjoy splashing in water without exposure to direct sun rays. Further, the present invention eliminates the necessity for small children to be in the vicinity of a conventional swimming pool. Additionally, the sun shade pool


100


of the present invention is lightweight, easy to assemble and disassemble, and is robust and stable in construction.
