INDEX TO RELATED APPLICATIONS
This application claims benefit to U.S. Provisional Patent No. 61/232,095 filed Aug. 7, 2009 and U.S. Provisional Patent No. 61/371,362 filed Aug. 6, 2010 the disclosures of which are incorporated herein by reference in their entirety.
BACKGROUND OF THE INVENTION
The recreation industry is replete with articles intended to improve the comfort and convenience of sunbathers, pool patrons, and beachgoers. The simple beach lounge has evolved into the central component of floating lounges. Typically, floating lounges are single and double units. A double unit usually includes a broad area for two persons to lounge side by side. While these floating lounges have provided greater service and convenience to their users they still have shortcomings. One particular shortcoming is that a user is required to enter and leave the floating lounge portion on the outermost edges of the elongated side. Another difficulty is the floating lounges do not generally provide for any removable shade devices.
The present invention addresses these problems. The floating lounge of the present invention provides a central corridor or passage through which the user may enter and lie down or sit on either lounge portion and the lounge has incorporated shade devices.
BRIEF SUMMARY OF THE INVENTION
In one embodiment the present invention provides a novel configuration for a floating lounge. The floating lounge provides for two users to have individual lounge chair type portions. Further the configuration of the present invention has a passageway between the individual lounge chair portions and provides the ability of a person to enter and leave in the area between the two lounge chair portions.
In one embodiment the floating lounge of the present invention may be described as:
A floating lounge comprising:
(a) a single base constructed and arranged to float while supporting up to 700 lbs.;
(b) two lounge portions on said base;
(c) a passage between said lounge portions sufficient to allow a user to pass; wherein said passage is adjacent to each of said portions.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The floating cabana or lounge 10 of the present invention is a floating lounge/cabana combination. Cabana 10 provides for a single base assembly 12. Base 12 may be made of any acceptable material such that the frame supports the desired weight and floats. Acceptable material must be such that it can support the weight at least 2 adults. Preferably, the base should be able to support 600 to 700 pounds.
Two lounge portions 14 and 16 extend outward from a platform area 20 such that the overall configuration is of a simplified squared letter “U.” The area between each of lounge portions 14 and 16 are constructed and arranged such that passage 18 is formed therebetween. Passage 18 allows a user to move within the area of passage 18 or at least come within the cabana area in the center passage.
Base 12 is preferably formed of a vacuum molded shell. Base 12 may be formed of a single piece or a plurality of pieces.
Sizes, weights, and dimensions provided herein represent a preferred configuration for illustrative purposes only and are not intended to limit the configuration. Additionally, the figures presented herein are for illustrative purposed and not necessarily drawn to scale. In one embodiment, base 12 is formed of 3/16th inch UV resistant plastic. UV refers to ultraviolet light. Base 12 is approximately twelve inches high and weighs between 80-100 lbs. Foam pads 15 and 17 are secured to base 12 by adhesive.
As shown in FIGS. 2-6, base 12 is constructed and arranged with an interior cavity 40. Base structural support assembly 42 is positioned in interior cavity 40. Base lid 50 is affixed to base 12 in any acceptable manner to create an air tight seal of base lid 50 on base 12.
As seen in FIGS. 1, 7, 8, and 9, base 12 has platform area 20 on one end and each of first lounge portion 14 and second lounge portion 16 extend in the same direction from platform area 20.
A particular difficulty arises in successfully configuring the cabana 10 of the present invention. Typical water vessels having elongated side flotation portions and a portion between the side flotation portions, such as a sailboat or catamaran, have the central portion substantially centered between the ends of the flotation portions. The present invention is configured with platform area 20 at one end of the vessel. This configuration in a substantial block u-shaped configuration represents engineering challenges. The article must be configured such that a person in the water can enter of depart either lounge portion 14 or 16 in either central cavity 18 or from the outer sides of either lounge portion 14 and 16 while cabana 10 maintains relative horizontal stability and does not tip over in the water.
In order to achieve the desired stability, each lounge portion is similarly configured with a concave curvature extending from the front end of each lounge portion 14 and 16 along the length thereof and extending though platform area 20 such that the curvature extends substantially along the entire length of each side of cabana 10.
As seen in FIG. 8, front face 60 of lounge portion 16 is configured with a base having a length 62, extending inward from inner wall 70 and outer wall 72. A curved portion 66 defines a curved cavity 76 (shown in FIG. 7) which extends the length of each side of cabana 10. Curved portion 66 has a maximum height 64 defined when cabana 10 is placed on a flat surface. The distance of lengths 62, height 64, and degree of curvature of curved portion 66 have been arrived at through careful experimentation and engineering such that a person entering cabana 10 from either passage 18 or from the outside of either lounge 14 or 16 does not tip over cabana 10 in the water.
The engineering of curved cavity 76 imparts the desired stability such that any displacement of cabana 10 from a substantially horizontal plane, when cabana 10 is in the water, does not tip over or capsize cabana 10.
As seen in FIG. 10, the curvature can be described as having a constant radius curve defined by each of curved portions 66 and 66′ under each of lounge portions 16 and 14 respectively. In one embodiment, the constant radius curve is a 13.5 inch constant radius curve. For illustrative purposes, axis 92 represents the horizontal plane in which the lowest points of base 12 lie. Base 12 has an outer curved inflection point 82 and 82′ that curve inward towards central axis line 110. Outer radius curve points 84 and 84′ lie in plane 92 and represent the point at which the constant radius curve defined by each of curved portions 66 and 66′ begin. Peak points 86 and 86′ represent the peak of the constant radius curve. In one embodiment, peak points 86 and 86′ have a peak height or amplitude 88 and 88′ being a vertical distance above plane 92. In one embodiment, base 12 has an overall height above plane 92 of approximately ten inches and amplitude 88 and 88′ is approximately 2.25 inches. Inner radius curve points 90 and 90′ define the length of the radius curve as being curvature along curve portion 66 and 66′ from outer radius curve points 84 and 84′. Each of inner radius curve points 90 and 90′ lie in plane 92. The horizontal length in relation to base 12 of each radius curve is defined by distance 100 and 100′ being the horizontal distance along plane 92 from 84 to 90 and 84′ to 90′ respectively.
Each of inner radius curve points 90 and 90′ represent a point of inflection wherein the curvature of base 12 continues inward until a horizontal bottom 112 of platform area 20 is reached. Horizontal bottom 112 has a height 96 from plane 92 to bottom of platform 20 at bottom point 94 of approximately 2 inches.
The present invention provides a floating cabana 10 with stability in the water such cabana tilts from sided to side when a person goes on or off either of lounge portions 14 or 16 such that the side to side tilting does not turn over or capsize the cabana.
While the invention has been described in its preferred form or embodiment with some degree of particularity, it is understood that this description has been given only by way of example and that numerous changes in the details of construction, fabrication, and use, including the combination and arrangement of parts, may be made without departing from the spirit and scope of the invention.
