SURFBOARD OR PADDLEBOARD SPLITTABLE INTO TWO PARTS
Abstract
A large surfboard or paddleboard cannot be carried in an
automobile or a train, but it is extremely convenient if it can. A
board using carbon fiber or glass fiber and an epoxy resin for
weight reduction is divided into two parts, two holes are provided
in each cut surface, a female pipe is inserted in each hole, two
male pipes to be fitted in each of the female pipes are used for
matching the both with each other, and both cut surfaces are firmly
fixed by a screw and a swing-preventing plate. Alternatively, a
retaining member using projections and recesses are provided and
the both cut surfaces are abutted to each other, and the cut
surfaces are firmly fixed. As above, the board which can be carried
in a train or in an automobile and in which bonding in use is
extremely easy and reliable is provided.

Claims
1. A surfboard or paddle board splittable into two parts,
characterized in that: the board is laterally divided into two
parts, two pipe holes are provided in each of cut surfaces, female
pipes are pushed into the holes and two male pipes are inserted
into the female pipes in the two holes of each part, respectively,
and then, the both parts are abutted to each other, and the both
ends of the board can be fixed by a screw.
2. The surfboard or paddleboard splittable into two parts according
to claim 1, wherein two swing-preventing members are used for
stabilizing joint by using projections and recesses of the cut
surfaces.
Description
BACKGROUND OF THE INVENTION
[0001] 1. Technical Field
[0002] The present invention relates to a surfboard or paddleboard
that can be easily carried and be divided into two parts.
[0003] 2. Background Art
[0004] The inventor of the present invention filed Japanese
Unexamined Patent Application Publication No. 11-59574. This
invention needs a large number of screws for fixing, and assembling
thereof is somewhat cumbersome.
[0005] An example proposed in a foreign country is fixed by a
single rod, but this has a defect that the rod is broken
easily.
SUMMARY OF INVENTION
[0006] Prior-art examples had a problem that assembling was
cumbersome. The present invention is firmly fixed and easily
assembled and is not broken easily as in the case of using a single
pipe. Moreover, materials of a wall, each pipe, and a male pipe are
carbon fiber or glass fiber and an epoxy resin, and thus, they are
tough.
[0007] The present invention is a surfboard or paddleboard
splittable into two parts obtained by laterally splitting a board
into two parts, in which two pipe holes are provided in each of cut
surfaces, female pipes are pushed into the holes, respectively, two
male pipes are inserted into two holes, respectively, and then,
they are abutted to each other, and the both ends of the board can
be fixed by a screw.
[0008] Since the present invention uses carbon pipes and there are
two pipes, strength is improved. Moreover, the material has
strength. The board can be carried in an automobile or a train and
can be made compact so that it can be handled extremely easily.
BRIEF DESCRIPTION OF DRAWINGS
[0009] FIG. 1 is a perspective view of a board;
[0010] FIG. 2 is a perspective view illustrating a pipe;
[0011] FIG. 3 is a plan view illustrating a swing-preventing
member;
[0012] FIG. 4 is a plan view of the board fixed as a single body;
and
[0013] FIG. 5 is an extended perspective view illustrating a
retaining plate.
DESCRIPTION OF EMBODIMENTS
[0014] Meaning of an embodiment of the present invention will be
described below on the basis of FIGS. 1 to 5. A board which is
strong and can be separated and joined firmly is provided.
[0015] As illustrated in FIGS., reference numeral 1 denotes a
nose-side board, and reference numeral 2 denotes a tail-side board.
Each of them has two female pipes that is, female pipes 3, 4, 5,
and 6. Moreover, swing-preventing female members 7 and 8 and male
members 9 and 10, that is, two members are provided respectively on
each board. They are abutted to each other in joining while all are
attached to thin walls 11 and 12.
[0016] The thin walls 11 and 12 and the two female pipes for each
part, that is, four pipes in total are firmly formed integrally.
Moreover, the male pipes are also formed of the same material.
[0017] The board is formed by carbon fiber or glass fiber and an
epoxy resin in order to reduce weight and to obtain strength. Even
a usual completed board can be made into a board splittable into
two parts by dividing a main body thereof, drilling a hole in each
part, inserting a female pipe therein and bonding it with a wall,
and removing projections. It is naturally possible to fabricate the
board as described above in advance and to offer it for sale.
[0018] The male pipes 13 and 14 are fitted in the female pipes 3,
4, 5, and 6 for both boards, respectively, and the both are joined
by using a screw and fixed. At this time, two members using
projections and recesses are matched with each other for preventing
swing.
[0019] Regarding the screw, a retaining plate 16 having two holes
15 is used to fit the screws in the holes, and the plate is fixed
across the both.
