Description
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.

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 15. 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 position.
It is desirable to provide a substantially streamlined shape for
the buoyant structure 1 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 three-point 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
1 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 surface and
to protect the exterior surface of the structure 1.
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 1 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 water (not
shown) with an occupant therein. The modified buoyant structure 30
has a buoyant upper portion 31 which is a hollow structure having
an upper member 32 shaped to provide a concave upper deck surface
33. Sidewalls 34 are substantially normal to the upper member 32
and extend from the peripheral edges thereof. End walls 36 and 37
extend from opposite ends of the upper member 32 and are connected
to the sidewalls 34 to form a continuous wall member normal to the
upper member 32. A bottom member or wall 38 is substantially
parallel to the upper member 32 and is secured to lower or outer
edges of the sidewalls 34 and the end walls 36 and 37 to provide an
enclosed buoyant chamber 39.
In the illustrated structure, one end of the buoyant upper portion
31 is upperwardly inclined to form a back portion 40 and the
generally horizontal deck portion 32. Arm portions 42 are formed by
transversely spaced walls 44 and 45 extending from the upper member
32 and closed by an upper wall 46 and an end wall 47.
Support portions 48 are illustrated as a front leg 49 and
transversely spaced rear legs 50 each being hollow members and
depending from the bottom wall 38 of the deck portion 32.
FIG. 8 illustrates a further modified buoyant structure 52
particularly useful as a floating toy having a buoyant deck portion
53, having a generally horizontal concave upper surface 54 adapted
to support an occupant, such as a child, thereon. The deck portion
53 is proportioned to position a center of buoyancy (not shown) for
stability when the occupant is supported thereon. The buoyant
structure 52 is adapted to be supported on a solid surface 55 and
to float on water (not shown) with an occupant therein and in the
illustrated structure support portions 56 depend from the deck
portion 53 for engaging the solid surface 55 for supporting the
deck portion 53 and the occupant thereon in a position above the
solid surface 55.
The buoyant surface 52 may assume the shape of some living
creature, such as an animal, reptile or the like, having legs 57
depending from the deck portion 53 to support an occupant thereon
in a position above the solid surface 55.
It is to be understood that while we have illustrated and described
certain forms of our invention, it is not to be limited to these
specific forms or arrangement of parts herein described and
shown.
