Abstract
A retractable pool shade, for use with a pool having a pool edge and a pool deck extending outside of the pool edge, having a shading assembly and a stand. The stand has a pair of horizontal members which extend parallel to each other and are supported by legs. The shading assembly includes a shading element which is selectively deployable along the horizontal members. Wheels are provided at the bottom of the legs to selectively provide mobility to the pool shade around the pool deck. Suction cups are associated with the legs to selectively engage the pool deck to maintain the stand in a stationary position.
Description




BACKGROUND OF THE INVENTION




The invention relates to retractable pool shade which is attached to a support stand having legs which each have wheels so that the shade can be easily moved to various locations surrounding the pool. The wheels can be retracted thereby allowing suction cups above each wheel to engage the deck of the pool, causing the pool shading assembly to be immobilized.




SUMMARY OF THE INVENTION




It is an object of the invention to produce a shade which can be used to protect people who are swimming in a pool from the direct rays of the sun. Accordingly, the shade extends directly over and across a pool to selectively block the sun from reaching the pool.




It is a further object of this invention to provide a shade which may be easily moved to various locations above and surrounding the pool. The repositioning of the shade will allow the pool to be continuously shaded from the sun, in spite of the differing position of the sun at various times of the day. Accordingly, the shade is supported by a frame having wheels which are selectively deployable to the ground to allow the shade to be moved so as to extend over different areas of the pool.




It is a further object of this invention to provide a shade assembly which, once it has been wheeled to a desired location, may be easily immobilized to remain at that location. Accordingly, by the retraction of the wheels, suction cups located above each wheel are able to contact and attach to a surface.




It is a further object of this invention to provide the owner with a product which allows easy interchangeability of the shading element with other designs and shapes, so that its use may be tailored to different occasions. Accordingly, the shading element can be made of fabric which is easily interchanged with other fabric shading elements-while using the same frame structure.




To the accomplishment of the above and related objects the invention may be embodied in the form illustrated in the accompanying drawings. Attention is called to the fact, however, that the drawings are illustrative only. Variations are contemplated as being part of the invention, limited only by the scope of the claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS





FIG. 1

illustrates a retractable pool shade


10


. Referring momentarily to

FIG. 4

, the pool shade


10


is used in conjunction with a pool


50


, defined by a pool edge


52


. The pool edge


52


is surrounded by a pool deck


54


. The pool edge


52


includes a pair of opposite sides


55


.




The pool shade


10


has a stand


12


and a shading assembly


14


. The stand


12


includes a pair of horizontal members


30


, which extend substantially parallel to each other. Each horizontal member


30


has a top surface


30


T having a longitudinal groove


32


. The horizontal members


30


have a proximal end


30


P and a distal end


30


D. The horizontal members


30


are each supported by a pair of legs


34


, wherein one leg is generally located at the proximal end


30


P of each horizontal member


30


, and another leg is generally located at the distal end


30


D of each horizontal member


30


D.




The shading assembly


14


includes a shading element


20


and a roller


22


for selectively storing and deploying the shading element


20


. Naturally, the shading element


20


is made of a sheet-like flexible material, such as plastic or fabric. The shading element


20


has a forward edge


20


F and a pair of sides


20


S, which extend parallel to each other. The shading element


20


is sized so that the sides


20


S of the shading element


20


correspond with the horizontal members


30


. The roller


22


is located near the proximal end of the horizontal member


30


. Accordingly, in deploying the shading element


20


, the forward edge


20


F of said shading element


20


is moved along the tops


30


T of the horizontal members


30


from the roller


22


at the proximal end


30


P of the horizontal members


30


toward the distal end


30


D of the horizontal members


30


.




Referring to

FIG. 2

, to facilitate smooth movement of the shading element


20


along the tops


30


T of the horizontal members


30


, the shading element


20


has a pair of runners


24


, each runner extending near and parallel to one of the sides


20


S of the shading element


20


. Referring to

FIG. 2

, each runner


24


is slidably mounted within one of the grooves


32


. Accordingly, the runners


24


guide the shading element as it is deployed, preventing lateral movement of the shading element


20


. Preferably, the groove is closed at both the proximal and distal end of the horizontal member to prevent the shade from extending past either of said ends.




It should be noted that the horizontal members


30


need not extend perfectly straight in the vertical plane. Accordingly, “horizontal” should be interpreted herein as “generally” horizontal, but not necessarily strictly horizontal. In particular, both horizontal members


30


may be arched upward in an identical fashion. Provided that the runners


24


are configured to engage the longitudinal grooves


32


in a suitable fashion to allow the runners to follow a possibly arched longitudinal groove


32


while remaining within said longitudinal groove


32


, the shading element can indeed follow such an arched configuration. Accordingly, the configuration shown in

FIG. 2

may be modified, as would be appreciated by one of ordinary skill in the art, to maintain the runner


24


within the groove


32


so as to follow a curved or angular redirection of the groove. In this regard, with such accomodation, the horizontal members may even be peaked at their center.




Referring once again to

FIG. 1

, a semicircular bracket


18


supports the roller


22


and extends perpendicularly between the horizontal members


30


at the proximal ends


30


P thereof. In order to deploy or retract the shade element


20


, the roller


22


is rotated by means of an axially mounted crank handle


16


. Rotation of the roller causes the shading element


20


to slide to various positions along the horizontal members


30


, thereby allowing the position of the shading element


20


to be adjusted even without necessitating the repositioning of the stand


12


. In order to maintain the horizontal members


30


parallel to each other, a pair of cross members


31


preferably extend between the horizontal members


30


at the proximal


30


P and distal


30


D ends thereof and extend perpendicular to the horizontal members


30


.




The legs


34


provide a means for supporting the shading assembly


14


. The legs


34


have a top portion


34


T, a bottom portion


34


B, and at least one leg side


34


S. Specifically, the top portion of the legs


34


T are attached immediately beneath the horizontal members


30


.




Wheels


36


are mounted to the bottom portion


34


B of each leg


34


, thereby allowing the retractable pool shade


10


to be moved to various positions surrounding the pool depending on the position of the sun and the desire of the user. In particular, the wheels


36


are mounted to the leg bottom


34


B using a caster frame


37


. The wheels


36


may be prevented from contacting the ground when the user desires to immobilize the retractable pool shade at a given position by using an immobilizing block


40


.




In particular, the immobilizing of the wheels is accomplished by pressing down on the immobilizing block


40


which is located above each wheel


36


. To accomplish the same, referring to

FIG. 3

, each immobilizing block


40


has a block top


40


T, a block bottom


40


B, and a bore


41


extending fully between the block top


40


T and block bottom


40


B. The bore


41


is sized and shaped to closely accommodate the leg


34


, such that the leg


34


extends fully through the bore


41


and allows the block to slide vertically upward and downward upon the leg


34


.




As illustrated in

FIG. 3

, attached to the side


34


S of each leg above the the leg bottom


34


B is a spring clip


38


. This spring clip is capable of supporting the weight of the immobilizing block


40


, and thereby maintaining the block


40


well above the leg bottom


34


B. When the immobilizing block


40


is positioned above the spring clip


38


, as seen in

FIGS. 1 and 3

, the wheels are not prevented from rolling on the pool deck and the retractable pool shade


10


is easily wheeled to any desired location along the pool deck


54


. Accordingly, the shade


10


may be easily repositioned as the position of the sun changes, and the user's need or desire for shade varies.




However, after the retractable pool shade has been rolled to its desired position, the block


40


is lowered to prevent further movement of the retractable pool shade


10


along the deck


54


, as seen in FIG.


4


. In order to lower the block


40


, the block


40


is pressed downward by the user. In this regard, the spring clip


38


which normally supports the weight of the block


40


and keeps it well above the wheel


36


on the side of the leg


34


S can be easily overcome by such pressure by the user, so as to allow the block to move below the spring clip toward the bottom of the leg


34


B. The block bottom


40


B will fall beyond the leg bottom


34


B such that the block bottom


40


B may come into direct contact with the pool deck


54


. By friction alone, the block


40


is capable of preventing the wheels


36


from rolling on the pool deck


54


, thus immobilizing the entire retractable pool shade


10


.




Additionally, referring once again to

FIG. 3

, suction cups


42


may be mounted to the block bottom


40


B. The suction cups


42


extend and are oriented downward from the block bottom


40


B to positively adhere to the pool deck


54


such that the block


40


is more effective at preventing the wheels


36


from rolling and thereby for immobilizing the pool shade


10


, as shown in FIG.


4


.




In use, after ensuring that the blocks


40


are elevated off the pool deck


54


, and preferably positioned above the spring clips


38


, the pool shade


10


can be wheeled to a desired location on the pool deck


54


by pushing against the stand


12


. Generally, it is positioned so that the pool shade extends across the pool


50


, with the legs


34


on opposite sides


55


of the pool


50


. Once suitably positioned, the blocks


40


are lowered to the deck


54


, engaging the deck with the suction cups


42


. Then, the shading element


20


may be deployed across the stand


12


by moving the forward edge


20


F of the shading element


20


across the horizontal members


30


toward the distal ends


30


D thereof. This is generally accomplished by turning the crank handle


16


to unreel the roller


22


which stores the shading element


20


. The user can adjust the position of the forward edge


20


F, and thereby the extent by which the shading element


20


extends across the horizontal members


30


, and/or move the stand to achieve the desired shading from the shading device


10


. When the sun changes position in the sky, or the user's desire for shade is otherwise altered, the shading element


20


can be retracted by turning the crank handle


16


to store the shading element


20


upon the roller


22


and/or the blocks


40


can be raised and disengaged from the deck


54


so that the stand


12


can be repositioned as desired.




In conclusion, herein is presented a pool shade which may be wheeled to any desired location and then immobilized by retracting the wheels and causing the overlying suction cups to contact the pool deck. The invention is illustrated by example in the drawing figures, and throughout the written description. It should be understood that numerous variations are possible, while adhering to the inventive concept. Such variations are contemplated as being a part of the present invention.
