1. Field of the Invention
The present invention relates to portable devices to provide shade from the sun. More specifically, a sun shade which is buoyant and can provide shade to users while in a swimming pool or other body of water. The shade is based upon a structure similar to an umbrella which is of common known in the art. The fabric cover for said umbrella is opaque so as to prevent the penetration of the rays of the sun. The frame of the umbrella is equipped with flotation devices which function to keep the structure afloat. The sun shade is oriented so the flotation devices are oriented toward the sun to protect the user from the sun's harmful rays. The shade is collapsible and can be placed in a carry bag for easy transport.
2. Description of the Prior Art
The prior art generally is directed to various structures, such as chairs, small swimming pools to which various attachments to umbrellas to provide shade from the sun. Generally the devices which are in the nature of a covered or shaded swimming pool have the covers clamped or otherwise attached to the side of said swimming pool. Additional prior art discloses a buoyant frame attached to a rigid support over which shade material is stretched. Another structure comprises a folding chair with an elongated back from which shade material is suspended, said shade material being attached by cord or string to the forward end of extensions incorporated in the arms of said chair thereby forming a space under said shade material for the occupant.
Additional prior art discloses an umbrella from which shade material generally of a design similar to a window shade is suspended and wherein said suspended shade material is oriented towards the sun.
The invention provides a collapsible sun shade in the general form of an umbrella, which is commonly known in the art. The material stretched over the umbrella frame is generally opaque so as to provide shade from the sun.
Attached to a portion of the circumference of the umbrella are buoyant devices. In the preferred embodiment, the flotation device is elongated, extruded foam plastic, such as styrofoam, which is generally of a circular cross section. These elongated plastic items are generally sold as floatation aids and commonly referred to as “noodles”. Two pieces of noodles are employed, one longer than the other. The longer noodle is affixed to a portion of the outer circumference of the umbrella by first piercing the foam plastic with the ends of the ribs of the umbrella frame. The noodle is affixed to said umbrella by flexible strips of material, fixedly attached to the fabric of said umbrella at one end and removably attached to said fabric at the other end by the use of material such as Velcro®. A second shorter “noodle” with a central cavity longitudinally therethrough is affixed to the handle of said umbrella to maintain an angular flotation attitude.
A further understanding of the present invention will become apparent upon consideration of the following detailed description taken in connection with the accompanying drawings, wherein:
A first embodiment of the present invention shall be discussed with reference to
The umbrella portion of the invention, 1, comprises a central support member, 10, having a first, or top, end, and a second, or bottom, end. A plurality of primary support members, extend radially from the top end of the central support member 10. Optionally, secondary support members 15b are attached to both the primary support members 15a and the central support member 10, providing support to the primary support members 15a. A first end of the secondary support member 15b is attached to the primary support member 15a. A second end of the secondary support members 15b is attached to the central support member 10, preferably slidably attached, enabling radial expansion and collapsing of pivotably attached primary support members 15a. A circular opaque covering, 20, having an inside surface, 23, and an outside surface, 25 and dimensioned to span the radial area of the primary support members, 15a, is fixedly attached to the primary support members 15a. The outer edge 40 of the cover 20 presents a perimeter.
The floatation portion of said invention comprises at least two buoyant members 30, 35, operable to float the device 1 on the surface of a body of water. In the preferred embodiment, the buoyant members 30, 35 are composed of buoyant foam plastic, such as Styrofoam®, but other buoyant materials are in the spirit of this invention. The preferred buoyant members 30, 35 are shaped with a generally circular cross-section and present a longitudinal axis therethrough. The preferred buoyant members 30, 35 comprise what are known as “noodles” in the flotation art. In an alternate configuration, the buoyant member 30 or 35 can comprise an inflatable plastic bladder.
The first buoyant member 30 is fixed, preferably removably, to the edge 40 of the cover 20 using a fastener. In a first configuration, the fastener comprises an end 17 extending from the primary support member 15a, where the end 17 extends slightly beyond the cover 20. One or more ends 17 is inserted or “poked” into the first buoyant member 30. In an alternate configuration, the fastener comprises one or more longitudinal attachment strips 28 secured to opposing surfaces 2325 of the cover 20 by means in the art such as hook and loop, gluing, or sewing. The longitudinal attachment strips 28 have a first end attached to the outside surface 25 of the cover 20. A second end 29 is attached, preferably removably, to the inside surface 23 of the cover 20. The attachment strip 28 defines a perimeter through which the first buoyant member 30 can be introduced.
The second buoyant member 35 is joined, preferably removably, to the bottom end of the central support member 10 using a coupling. The second buoyant member 35 is preferably substantially shorter than the first buoyant member 30. The preferred coupling comprises a bore 37, approximately the diameter of the central support member 10, through the longitudinal axis of the second buoyant member 35. The coupling may further comprise a connection strip 39, a flexible strip of material for tightly wrapped around the second buoyant member, 35, in order to further prevent unwanted longitudinal movement along the central support member, 10.
In preparation for use, said ends, 17, are inserted into said first buoyant member, 30, at several points along the edge 40 of the cover 20. The first ends of the attachment strips, 28 are attached to the outside surface 25 of said opaque cover, 20. The second ends, 29, of the attachment strips, 28 are attached to the inside surface, 23, of said opaque covering, 20. The second buoyant member 30 is attached to the bottom end of the central support member 10. The sun shade 01 is placed on the body of water with the outer surface 25 of the cover 20 facing the sun.
The invention has been described with reference to certain preferred embodiments thereof. It will be understood, however, that modifications and variations are possible within the scope of the appended claims. The invention is not limited to the specific mechanical structures illustrated in the preferred embodiments for folding sun shades, but instead, is intended to cover any buoyant, foldable umbrella used as a sun shade.
