United States Patent O 3,499,647 AQUATIC RECREATIONAL AND EDUCATIONAL DEVICE Max F. Nestler, RD. 1, Leesport, Pa. 19533 Filed Jan. 23, 1968, Ser. No. 699,948 Int. Cl. A63g 31/.00; A63h 23/00; B63b 21/52 U.S. Cl. 2721 Claims ABSTRACT OF THE DISCLOSURE A board having weights on its bottom.

A number of float members are detachably connected to rings extending upwardly from the board. In use, persons can take turns remaining under water and removing as many elements as possible while holding their breath.

SUMMARY OF THE INVENTION A flat weighted board was secured to the upper surface a plurality of spaced apart rings which are vertically displaced upward from the surface. A like plurality of vertical members or elements such as bowling pins, are each provided at the bottom end with a snap hook detachably engaging the corresponding ring. The board can rest on the bottom of the lake, pool, river, ocean or other body of water for use in the manner described above.

The members can be lighter than water so that they will remain upright when secured to the rings and will float upward to the surface of the water when released.

BRIEF DESCRIPTION OF THE DRAWINGS In the drawings:

FIG. 1 is a top view of my invention;

FIG. 2 is a bottom view thereof;

FIG. 3 is a side view thereof as taken through 3--3 in FIG. 1; and

FIG. 4 is an end view but with the members removed as taken through 4-4 in FIG. 1.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT Referring now to FIGS. 1-4, a thin flat rectangular fiberglass board has two opposite disposed weighted elongated bars 12 of lead or other metal whereby the responding holes in the board with threaded ends which are secured to nuts 26 on the bottom surface of the board.

A plurality of floats 28, each having the shape of a bowling pin, are employed. A vertically downward extending snap hook 30 is secured to the bottom end of each pin and detachably engages a corresponding one of rings 22. Typically there can be twenty-one pins.

The resulting structure can then be used as described above. In addition to such uses, it can also be used in training divers to carry out working operations under water.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. An aquatic recreational and educational device comprising:

a flat board extending horizontally;

weight means secured to the bottom surface of the board;

a plurality of rings extending vertically upward and vertically displaced above the top surface of the board; and p 1 a like plurality of vertical members, each detachably secured at its bottom end to a corresponding ring.

2. A device as set forth in claim 1 wherein said weight means includes first and second horizontal spaced apart parallel weighted bars.

3. A device as set forth in claim 2 wherein each ring has a shank extending vertically downward therefrom and secured at its bottom end to said board,

4. A device as set forth in claim 3 wherein each vertical member is a float having the shape of a bowling pin.

5. A device as set foith in claim 4 wherein a separate snap hook is secured to the bottom end of each pin to detachably secure same to the corresponding ring.
