Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to recreational flotation devices and more particularly pertains to a float with sun shade which may be employed to float a human on a body of water while simultaneously providing shade from the sun for a portion of the human. 
     2. Description of the Prior Art 
     The use of rafts and flotation devices is known in the prior art. More specifically, rafts and flotation devices heretofore devised and utilized for flotation of a human body upon a body of water are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements. 
     The present invention is directed to improving devices for a float with sun shade in a manner which is safe, secure, economical and aesthetically pleasing. 
     For example, U.S. Pat. No. 4,894,033 to Chang discloses a multipurpose and inflatable raft. The Chang invention comprises an inflatable circular raft unit, an inflatable spherical raft unit, and an inflatable back seat wherein each raft unit has several retainer plates disposed thereon for the purpose of interconnection and providing a raft of high buoyancy susceptible to introduction of a pedaling device. The Chang invention has no provision for shielding humans disposed thereupon from sunlight. The present invention comprises a raftlike floatation device having a sun screening provision for all or portions of a human disposed thereupon. 
     In U.S. Pat. No. 5,049,102 to Hull a recreational raft apparatus is disclosed comprising an inflatable raft portion with an inflatable pillow and at least one closable pocket portion, and furthermore includes a clip fastened towel cover for the topmost side of the invention. There is no provision in the Hull invention for shading the user from sunlight. The present invention comprises an inflatable raft having a sun shade which screens potentially harmful sunlight from a human disposed thereupon. 
     In U.S. Pat. No. 4,750,447 to Spinosa et al. an inflatable life raft is disclosed comprising an inflatable passenger receptacle having a removable canopy for covering the passenger receptacle. The Spinosa et al. invention treats a non-recreational life raft having pockets for survival gear and automated inflation devices, and furthermore the user of the Spinosa et al invention is disposed therein in a substantially seated position wherein the raft conforms to the buttocks, back, and legs of the user. The Spinosa invention has a plurality of bleeder cords in communicating air chambers thereby facilitating inflation and deflation during emergencies. The removable canopy is devised to protect the user from the effects of waves and high winds and, although effective as a sunshade, does not provide for free air flow therethrough wherein the user is susceptible to extreme discomfort and dehydration if the Spinosa et al. raft is used for recreational purposes in warm weather. The present invention comprises a substantially planar inflatable raft having a sun shade disposed upon an inflatable raft portion thereof. The sun shade of the present invention may be an inflatable section or an unrolling shade, or a meshlike screen susceptible to blocking a portion of sunlight passing therethrough yet permitting substantially free passage of breezes. 
     In U.S. Pat. No. 4,127,909 to Pizzo an inflatable raft construction and method is disclosed for simplified construction of substantially right angle tubular joints in inflatable rafts. A disadvantage in this prior art lies in a lack of provision for attaching a sun shade to a raft so constructed, and furthermore the Pizzo invention requires substantially orthogonal disposition of tubular communicating raft portions. The present invention requires disposition of a sun shade upon a portion of the raft structure and additionally the present invention does not generally employ orthogonally disposed communicating tubular portions. 
     U.S. Pat. No. 5,205,086 to Heim discloses an inflatable tent. The disclosure teaches a tent having a flexible canopy, a floor, and a series of inflatable tubes serving as frame hoops. The disclosure makes no provision for flotation of humans for recreational purposes. Furthermore, there are no provisions for a partial enclosure forming a sun shade. The present invention comprises a raftlike inflatable flotation device having a fixed or deployable sun shade disposed thereon. 
     In this respect, the float with sun shade according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of providing recreational flotation of humans with substantial protection from sunlight. 
     Therefore, it can be appreciated that there exists a continuing need for new and improved floats with sun shades which can be employed for recreational human flotation without the potentially adverse action of sunlight. In this regard, the present invention substantially fulfills this need. 
     As illustrated by the background art, efforts are continuously being made in an attempt to improve raftlike flotation devices. No prior effort, however, provides the benefits attendant with the present invention. Additionally, the prior patents and commercial techniques do not suggest the present inventive combination of component elements arranged and configured as disclosed and claimed herein. 
     The present invention achieves its intended purposes, objects, and advantages through a new, useful and unobvious combination of method steps and component elements, with the use of a minimum number of functioning parts, at a reasonable cost to manufacture, and by employing only readily available materials. 
     SUMMARY OF THE INVENTION 
     In view of the foregoing disadvantages inherent in the known types of rafts, and inflatable flotation devices now present in the prior art, the present invention provides an improved float with sun shade construction wherein the same can be utilized for recreational human flotation in direct sunlight while shielding the human at least in part from receiving a significant solar radiation dosage. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved float with sun shade apparatus and method which has all the advantages of the prior art rafts and human flotation devices and none of the disadvantages.

The float with sun shade 10 comprises a raftlike flotation portion 16 having disposed thereon a sun shade support portion 18 and a pull down sun shade 20. In use, a human lies upon the raftlike flotation portion 16 having their head positioned at an and of the raftlike flotation portion 16 substantially beneath the sun shade support portion 18 and manually moves pull down sun shade 20 to one side or another to effectively block sunlight from reaching the user&#39;s face. 
     More specifically, it will be noted that the float with sun shade 10 comprises raftlike flotation portion 16 which is formed into sun shade support portion 18 by a first ninety degree bend 30 and a second ninety degree bend 32. See FIG. 2. Raftlike flotation portion 16 comprises a multi-compartmented polymeric structure susceptible to being inflated by introduction of a volume of air therewithin. Raftlike portion 16 has a first end portion 34, a central portion 36, and a second end portion 38. First end portion 34 is a free end thereof and is rounded forming a smoothly curving terminating surface 40. Second end portion 38 terminates at first ninety degree bend 30 of sun shade support portion 18. Central portion 36 comprises a plurality of inflated communicating compartments 50 thereby providing a significant buoyant force adequate to furnish flotation of a human disposed thereupon. See FIG. 3. Communicating compartments 50 are bonded or otherwise joined at seams 52. Ports 54 disposed between adjoining compartments 56 and 58 permits air flow communicatively therethrough. Raftlike flotation portion 16 may be of vinyl or rubberized cloth composition, or any other construct which provides a durable inflatable platform substantially unaffected by water contact and sunlight impingement. 
     Sun shade support portion 18 comprises an extension of a first compartment 60 and a second compartment 62 wherein first and second compartments 60 and 62 are the outermost of communicating compartments 50. See FIG. 4. First compartment 60 and second compartment 62 form sun shade support portion 18 by a framelike structure comprising first ninety degree bend 30, first tubular support portion 64, second ninety degree bend 32, second tubular support portion 66, third ninety degree bend 68, support interface tube 70, fourth ninety degree bend 72, third tubular support portion 74, fifth ninety degree bend 76, fourth tubular support portion 78, and sixth ninety degree bend 80. See FIG. 5. First ninety degree bend 30 and sixth ninety degree bend 80 comprise extensions of compartments 60 and 62 wherein a right angular bend is made thereto without substantial change in the free internal diameter of either compartment 60 or compartment 62. 
     First ninety degree bend 30 and sixth ninety degree bend 80 result in a substantially parallel disposition of first tubular support portion 64 and fourth tubular support portion 78, and furthermore result in a substantially orthogonal disposition of first tubular support portion 64 and fourth tubular support portion 78 with respect to a plane substantially containing a major surface of raftlike flotation portion 16. Second ninety degree bend 32 and fifth ninety degree bend 76 result in a substantially parallel disposition of second tubular support portion 66 and third tubular support portion 74, and furthermore result in a substantially parallel disposition of second tubular support portion 66 and third tubular support portion 74 with respect to a plane substantially containing a major surface of raftlike flotation portion 16. Third ninety degree bend 68 and fourth ninety degree bend 72 provide a disposition of support interface tube 70 wherein support interface tube 70 lies in a plane substantially parallel to a plane substantially containing a major surface of raftlike flotation portion 16. 
     Referring again to FIG. 4 and to FIG. 5 pull down sun shade 20 comprises a first fixed shade portion 82, a second fixed shade portion 84, and a pull down portion 86. Pull down sun shade 20 may be of polymeric composition such as a substantially opaque vinyl sheet or as a meshlike screen wherein the vinyl sheet blocks sunlight and air flow, and the meshlike screen blocks a portion of sunlight and permits some air flow therethrough. First fixed shade portion 82 is affixed to second tubular support portion 66, third ninety degree bend 68, support interface tube 70, fourth ninety degree bend 72, third tubular support portion 74 by a continuous bond thereto wherein the continuous bond may be a weld or adhesive fastening.
