SHEET 2 [IF 3 INVENTORS. J'eun B.Wilson,-d BY Dell Y. Angerer ATTORNEYS CHAIR-BOAT STRUCTURE The present invention relates to buoyant structures and more particularly to buoyant chairs, lounges, supports, toys, and the like for use in water or on a solid surface.

The principal objects of the present invention are: to provide a buoyant structure adapted to support an occupant therein when the chair is on a solid surface or floating in water; to provide such a buoyant structure wherein the occupant may assume a comfortable seated and reclining or lounging position; to provide such a buoyant structure adapted to support the occupant in a dry position while the structure is floating in water; to provide such a buoyant structure of unitary and sturdy construction which is safe from loss of buoyancy and particularly stable in use to permit an occupant therein to move as desired and as necessary to manually propel the structure; to provide such a unitary buoyant structure of novel shape formed of unicellular buoyant material which is economical to manufacture, durable in use, light weight in construction so as to be easily transported between solid supporting surfaces and bodies of water, and particularly well adapted for the proposed use.

Other objects and advantages will become apparent from the following description taken in connection with the accompanying drawings wherein are set forth by way of illustration and example certain embodiments of this invention:

Referring more in detail to the drawings:

The reference numeral 1 generally designates a buoyant structure adapted to be supported by solid supporting surface 2 and to float on water (not shown) with an occupant 3 therein. The buoyant chain 1 has an elongate buoyant deck portion 4 having a generally horizontal concave upper surface 5 adapted to support the occupant 3 thereon. The buoyant structure 1 is proportioned to position a center of buoyancy for stability when the occupant 3 is supported thereon and for stability when on the surface 2. The buoyant structure 1 has support portions 6 depending from the deck portion 4 for engaging the surface 2 for supporting the deck portion 4 and the occupant 3 thereon in a position above the surface 2.

The buoyant structure 1 may be formed in a plurality of shapes such as in the form of buoyant toys, chairs and the like. In the preferred embodiment, the buoyant structure 1 is illustrated as a chair having back portion 7 extending upwardly and rearwardly from a rearward end of the deck portion 4 to permit the occupant 3 to assume a comfortable position, such as a reclining or lounging position, therein. Arm portions 8 and 9 extend upwardly from opposite sides of the deck portion 4 adjacent the rearward end thereof to increase the comfort of the occupant 37 within the buoyant chair 1. The support portions are illustrated as a front leg 10 and a pair of rear legs 11 and 12 depending from the deck portion 4 for engaging the supporting surface 2 to support the chair 1 and occupant 3 therein.

In the illustrated structure, the elongate deck portion 4 has a forward end 14 and a rearward end 15 joined by the back portion 7 and the deck portion 4 has opposed

side edges

16 and 17 extending between the forward and rear ends 14 and IS. The arm portions 8 and 9 extend upwardly from each of the

side edges

16 and 17 adjacent the rearward end 15 of the deck portion 4. The deck portion 4, back portion 7, and the arm portions 8 and 9 are sized to support the occupant 3 in comfortable position, such as reclining position with their legs 18 supported on the deck portion 4.

The back portion 7 intersects the deck portion 4 to form an obtuse angle 19 with the generally horizontal deck portion 4 thereby permitting the occupant 3 to assume a reclining or lounging position intermediate an upright position and a supine position. The back portion 7 also has a concave interior surface 20 merging with the concave upper surface 5 of the deck portion 4 to provide a smooth transition between the deck and back portions 4 and 7.

The arm portions 8 and 9 each have an upper surface, 21 and 22 respectively, which extends substantially normal or perpendicular to the back portion 7 whereby the occupant 3 in the chair 1 may support their

arms

23 and 24 in a natural or comfortable position while reclining or lounging therein.

Each of the arm portions 8 and 9 has an arcuate interior surface, 25 and 26 respectively, which merges with the concave upper surface 5 of the deck portion 4 and the concave interior surface 20 of the back portion 7 to provide a smooth transition between the back portion 7, deck portion 4, and the arm portions 8 and 9.

The buoyant chair structure 1 is adapted to support the occupant 3 in a completely dry position while the chair 1 is floating in water (not shown) and the deck portion 4 has a length sufficient to support the legs 18 of the occupant 3 maintain same above the water, however, the arm portions 8 and 9 terminate at a point sufficiently rearwardly of the forward end 14 of the deck portion 4 to permit the occupant 3 to place their legs 18 into the water while remaining in the reclining positron.

It is desirable to provide a substantially streamlined shape for the buoyant structure I to direct the water therearound in smooth unbroken flow, therefore, the front leg 10 and the forward end 14 of the deck portion 4 are shaped to part the water when the chair 1 is suitably propelled in a forward direction, as by a paddle (not shown). The front leg 10 has a planar bottom surface 27 for engaging the supporting surface 2 and the front leg 10 is illustrated as a generally conical structure tapering rearwardly from the forward edge 14 of the deck portion 4 to form a bowlike portion of the structure 1.

The rear legs 11 and 12 are transversely spaced apart and depend from the rearward end 15 of the deck portion 4 adjacent the rearward portion of the

side edges

16 and 17. The rear legs 11 and 12 also have

planar bottom surfaces

28 and 29 respectively to engage the supporting surface 2 and in cooperation with the front leg 10 provide a triangular threepoint support for the buoyant chair structure 1. Forward edges of the rear legs 11 and 12 are also arcuate and conically shaped to part the water when the chair I is suitably propelled in a forward direction.

As illustrated in FIG. 6, the buoyant chair 1 is formed of a suitable rigid, lightweight plastic foam material, such as polystyrene plastic or other suitable thermoplastic material of closed cell or unicellular construction which is light weight and rigid. It is desirable that the surface be specially treated, as by heating or coating same to provide a hard, waterproof sur face and to protect the exterior surface of the structure I.

To use the buoyant structure 1 for floating in a body of water (not shown) the structure 1 is placed therein and the occupant 3 assumes a lounging or reclining position with their legs 18 supported on a forward portion of the deck portion 4. The chair and occupant may be permitted to float in an uncontrolled random manner while the occupant relaxes or the chair I may be suitably propelled, as by a paddle (not shown), to move the chair to a desired location within the body of water. When it is desired to place the chair 1 on a suitable supporting surface 2, such as on a floor, patio, a dock, a walk adjacent a swimming pool, or the like, the chair is simply removed from the water and positioned with the bottom surface 27 of the front leg 10 and the

bottom surfaces

28 and 29 of the rear legs 11 and 12 engaging the respective supporting surface 2. The occupant 3 may then assume a sitting or reclining position therein.

FIG. 7 illustrates a modified buoyant structure 30 formed of hollow members to provide the necessary buoyancy to float on 3 4 water (not shown) with an occupant therein.
