DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As required, detailed embodiments of the present invention are disclosed herein. However, it is to be understood that the disclosed embodiments are merely exemplary of the invention which may be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed structure. [0021]
Reference is now made to the drawings, wherein like characteristics and features of the present invention shown in the various FIGURES are designated by the same reference numerals. [0022]
FIG. 1 shows an [0023] aluminum segment 2, consisting of a hallow tube having a cylindrical shape, a circular ring 19 on one end and a grip 3 on the other end.
FIG. 2 shows [0024] joint 4 with side openings, one of which can be used to insert grip 3 of segment 2 and attach it thereto.
FIG. 3 shows that [0025] grip 3 of cylindrical hallow tubes or segments 6 can likewise be inserted inside an opposite side opening of joint 4, to assemble a pair of side arms 7, with combinations of aluminum segments 2 and 6.
FIG. 4 shows how [0026] grip 3 of segments 2 and 6 is locked inside joint 4. Each grip 3 has a pin 64 which retracts inside grip 3 as a spring 65 is pressed. As the spring then returns to its normal extended position, pin 64 locks grip 3 inside a central chamber on joint 4.
FIG. 5 shows a set of three identical rectangular-like [0027] inflatable sacks 8. Each inflatable sack 8 has two separate inner longitudinal passages 10 across its width, which end on C-shaped recesses 11 on the long sides of said sacks. The longitudinal passages 10 are shown generally parallel with their counterpart passages but spaced not so distantly to be adequately separated from the edges of the short sides of said rectangular-like sacks.
FIG. 6 shows how connected [0028] segments 2 and 6 can be snugly fitted inside inner longitudinal passages 10 to assemble sets of side by side inflatable sacks 8, with said rigid aluminum segments 2 and 6 located well underneath the cushioned surfaces of said sacks when inflated. Circular rings 19 at the end of the pair of side arms 7 (formed by connected segments 2 and 6) are located within C-shaped recesses 11 and thus do not protrude beyond the main periphery of said rectangular-like sacks. Joints 4 connecting segments 2 and 6 are also shown within opposing C-shaped recesses 11.
FIG. 7 shows a series of [0029] slats 44 joined together by two pairs of elastic and parallel bands 101. The slats can be made of aluminum. As shown in this
FIGURE the elastic bands secure the slats side by side to comprise a straight aluminum sheet. The elastic bands thus allow the slats to be readily positioned in horizontal alignment. [0030]
FIG. 8 shows the series of [0031] slats 44 no longer in horizontal alignment but rolled up as elastic bands 101 hold them together. This rolled or folded position of slats 44 facilitates their storage and transportation when not in use.
FIG. 9 shows [0032] slats 44 as they form a flat and rigid surface secured by elastic bands 101 and also a pair of rigid parallel aluminum tubes 102 removably attached underneath said slats by suitable fasteners (e.g., screws). Tubes 102 are interconnected to four perpendicular tubes 87, also underneath slats 44. Each of the four perpendicular tubes 87 is then connected to a circular ring 18. Aluminum tubes 102 rigidly support slats 44, so that the set of slats comprise a flat and firm underwater surface, even as people stand and walk over it. But as said aluminum tubes 102 are removed and said slats 44 are again joined together only by the two pairs of elastic bands 101, the slats can be rolled up as previously shown in FIG. 8.
FIG. 10 additionally shows four separate short [0033] vertical aluminum segments 22. Each short segment 22 is secured to a different circular ring 18. Short vertical segments 22 are passed through circular rings 18 and removably attached thereto with pins 20 passing through holes 90.
FIG. 11 shows a set of three [0034] inflatable sacks 8 and a pair of side arms 7 connected to a side of slats 44 and another set of three inflatable sacks 8 and a pair of side arms 7 secured to an opposite side of said slats 44. The slats and the two sets of inflatable sacks are all shown connected at approximately the same level. Slats 44 are connected between the pairs of side arms 7 and the two sets of inflatable sacks 8 with aluminum short vertical segments 22, which secure circular rings 19 and 18. Each one of the four short vertical segments 22 passes through a circular ring 19 (of segments 2 of side arms 7) and a circular ring 18 (of perpendicular tubes 87), and is removably secured thereto with upper pins 58 and lower pins 20, which rest on corresponding holes 98 and 90. Upper pins 58 thus secure short vertical segments 22 to circular rings 19 while lower pins 20 secure the same short vertical segments to circular rings 18. Circular rings 18 are located underneath circular rings 19.
FIG. 12 then shows the [0035] apparatus 50, which includes four additional vertical segments, namely, long vertical segments 28, which are attached over short vertical segments 22 and are in essence an extension of said short vertical segments.
FIG. 13 shows the [0036] apparatus 50 as it is deployed for use, with slats 44 aligned horizontally and lowered a few feet under inflatable sacks 8 to provide a recreational underwater platform, while said inflatable sacks float on the water surface, providing cushioned above the water platforms on opposite sides of said slats and also support and stability to the entire apparatus. The underwater platform provided by the lowered slats enable people to stand and walk with their lower bodies under water. To lower slats 44 as shown in this FIGURE the four upper pins 58 are removed from corresponding holes 98 so that short and long vertical segments 22 and 28 can slide downward. Upper pins 58 are thus shown in FIG. 13 resting on holes 99 (not 98) in the upper end of long vertical segments 28. Holes 99 are located immediately under stopper 29 on top of long vertical segments 28. However, vertical segments 28 can also have other intermediate holes (not shown) between holes 99 and 98, where pins could rest to hold the underwater platform at an intermediate depth. Stoppers 29 are designed to stop the downward slide of short and long vertical segments 22 and 28 so that upper pins 58 can be more easily introduced on holes 99.
FIG. 14 shows a small-sized [0037] inflatable sack 149 underwater, underneath lowered slats 44 and tubes 102 and 87. This small inflatable sack is optional and has a flexible air hose 167 connected to an air pump 168 out of the water. Inflatable sack 149 is designed to remain deflated while apparatus 50 is deployed for use and is intended to be inflated only to facilitate the lifting of the underwater platform (comprised of slats 44, elastic bands 101, and tubes 102 and 87) from beneath the water surface, once upper pins 58 are removed from holes 99.
