PADDLEBOARD
Abstract
A paddleboard includes a hollow paddleboard body made of
plastics by rotational forming and having an enclosed chamber
defined in between opposing top wall and said bottom wall thereof
and inflated with air, and a plurality of hollow posts connected
between the opposing top wall and bottom wall of the hollow
paddleboard body. Each hollow post has a bottom close end connected
to the bottom wall of the hollow paddleboard body, and a top open
end connected to the top wall of the hollow paddleboard body and
exposed to the atmosphere.

Claims
1. A paddleboard, comprising: a hollow paddleboard body made of
plastics by rotational forming, said hollow paddleboard body
comprising opposing top wall and bottom wall and an enclosed
chamber defined in between said top wall and said bottom wall; and
a plurality of hollow posts connected between the opposing top wall
and bottom wall of said hollow paddleboard body.
2. The paddleboard as claimed in claim 1, wherein said enclosed
chamber is inflated with air.
3. The paddleboard as claimed in claim 1, wherein each said hollow
post has a bottom close end formed connected to the bottom wall of
said hollow paddleboard body and a top open end connected to the
top wall of said hollow paddleboard body and exposed to the
atmosphere.
4. The paddleboard as claimed in claim 1, further comprising an
anti-slip pad bonded to the top wall of said hollow paddleboard
body.
5. The paddleboard as claimed in claim 4, wherein said anti-slip
pad is prepared by EVA (ethylene vinyl acetate).
6. The paddleboard as claimed in claim 4, wherein said hollow posts
are arranged in said enclosed chamber subject to a predetermined
pattern.
Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to recreational water boards
and more particularly to a paddleboard, which is inflatable and has
hollow posts arranged therein to reinforce the structural
strength.
[0003] 2. Description of the Related Art
[0004] A paddleboard is a water recreational board that can be
paddled by hand, ridden on the waves or towed behind a power boat.
Conventionally, paddleboards are made in the same way as the
fabrication of a surfboard, generally comprising a polyurethane
base member trimmed by labor or by a CNC lathe, an epoxy resin or
glass fiber cover layer surrounding the polyurethane base, and a
design bonded to or printed on the surface of the epoxy resin or
glass fiber cover layer after the epoxy resin or glass fiber cover
layer is polished. This design of paddleboard has the drawbacks of
low structural strength and high manufacturing cost, and may be
broken easily when the player applies a pressure to the paddleboard
through the legs.
[0005] In order to enhance the structural strength for carrying the
weight of a heavy user, the thickness of the paddleboard may be
increased. However, increasing the thickness of the paddleboard
relatively increases its weight and cost.
SUMMARY OF THE INVENTION
[0006] The present invention has been accomplished under the
circumstances in view. It is therefore the main object of the
present invention to provide a paddleboard, which has the
characteristics of light weight and high structural strength and
inflatability, and allows the user to stand up on it positively and
comfortably.
[0007] To achieve this and other objects of the present invention,
a paddleboard comprises a hollow paddleboard body made of plastics
by rotational forming and having an enclosed chamber defined in
between opposing top wall and said bottom wall thereof and inflated
with air, and a plurality of hollow posts connected between the
opposing top wall and bottom wall of the hollow paddleboard body.
Each hollow post has a bottom close end connected to the bottom
wall of the hollow paddleboard body, and a top open end connected
to the top wall of the hollow paddleboard body and exposed to the
atmosphere.
[0008] Further, an anti-slip pad is bonded to the top wall of the
hollow paddleboard body. Preferably, the anti-slip pad is prepared
by EVA (ethylene vinyl acetate).
BRIEF DESCRIPTION OF THE DRAWINGS
[0009] FIG. 1 is an exploded view of a paddleboard in accordance
with the present invention.
[0010] FIG. 2 is an elevational assembly view of the paddleboard in
accordance with the present invention.
[0011] FIG. 3 is a sectional side, in an enlarged scale, of a part
of the paddleboard in accordance with the present invention.
[0012] FIG. 4 is a schematic drawing illustrating an alternate form
of the paddleboard in accordance with the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0013] Referring to FIGS. 1.about.3, a paddleboard in accordance
with the present invention is shown comprising a hollow paddleboard
body 1 made of plastics by rotational molding, and an anti-slip pad
15 bonded to the top wall 11 of the hollow paddleboard body 1.
[0014] The hollow paddleboard body 1 has an enclosed chamber 14
defined therein and inflated with air, and a plurality of hollow
posts 13 connected between the top wall 11 and the bottom wall 12.
Each hollow post 13 has the bottom end thereof closed and formed
integral with the bottom wall 12 of the hollow paddleboard body 1
and a top end provided with a top opening 132 that is exposed to
the outside of the top wall 11 of the hollow paddleboard body 1 and
kept in communication with the inside space 131 of the respective
hollow post 13. Further, the anti-slip pad 15 is prepared by, for
example, EVA (ethylene vinyl acetate). Thus, the user can stand up
on the anti-slip pad 15 positively and comfortably when playing the
water game. As the hollow paddleboard body 1 is inflated with air,
the weight of the paddleboard is minimized and its buoyancy is
maximized.
[0015] Further, the hollow posts 13 can be arranged subject to any
of a variety of patterns. FIG. 4 illustrates an alternate form of
the arrangement of the hollow posts 13.
[0016] Although a particular embodiment of the invention has been
described in detail for purposes of illustration, various
modifications and enhancements may be made without departing from
the spirit and scope of the invention. Accordingly, the invention
is not to be limited except as by the appended claims.
