Description
TECHNICAL FIELD
[0001] The present invention relates to a wax scraper for surfboard
for use in scraping off wax coated on a surfboard.
BACKGROUND ART
[0002] Surfing is one of typical marine sports. A surfer slides
down upcoming waves in a posture of standing on a surfboard while
keeping a balance. Wax is applied to all the points of the
surfboard, with which the surfer contacts, such that the surfer
does not slip on the surfboard. Additionally, for the purpose of
increasing gripping power, the surfer sometimes makes lines on the
surface of the wax coated on the surfboard, or makes the surface of
the wax rough.
[0003] The wax is commercially available from some manufacturers.
The wax corresponding to the level of water temperature is used so
as to achieve suitable gripping power. Therefore, when he/she surfs
for the first time in a day, or when the gripping power is
decreased, he/she scrapes off old wax coated on the surfboard, and
applies new optimum wax corresponding to the level of water
temperature. At the time of scraping off the wax, a wax scraper is
used.
[0004] Conventionally, the scraper for surfboard has a scraping
blade for scraping off the wax, which is formed on a side of a
plate member. Additionally, comb teeth for making lines on the
surface of the wax or making the surface of the wax rough are
integrally formed together in the scraper for surfboard (see Patent
Document 1).
[0005] Further, wax is also applied to skis and snowboard, but the
intended purpose of this wax is to make running surfaces of the
skis and snowboard slide better. Therefore, the function of the wax
for skis and snowboard is quite different from the function of the
wax for surfboard as non-skid wax. The wax for skis and snowboard
is applied to the running surface, and then scraped off from the
running surface with use of a wax remover for skis, such that the
thickness of the wax layer remained on the running surface becomes
as thin as possible. As described in Patent Document 2, the wax
remover for skis has a box shape with its upper portion opened, and
consists of a main body having a bottom surface with a long hole, a
scraping blade provided to the main body so as to protrude from the
long hole, and a lid portion having a box shape so as to cover the
upper portion of the main body.

SUMMARY OF INVENTION
Problems to be Solved by the Invention
[0008] The wax scraper for surfboard described in Patent Document 1
has a problem, because waste of the removed wax falls and makes the
surroundings dirty.
[0009] According to the wax remover for skis described in Patent
Document 2, since the wax is thinly scraped off by the scraping
blade and enters the main body through the long hole, the waste of
wax does not fall in the vicinity. However, since the wax remover
for skis has the long hole for receiving the waste of wax in the
middle of the bottom surface of the main body with which the
running surface of the skis contacts, it is necessary to provide
the scraping blade and the main body separately from each other,
such that the scraping blade slightly protrudes from the long hole.
Additionally, since the wax remover for skis is configured to
scrape off the wax such that the thin wax layer remains on the
running surface, it is necessary to provide a sharp scraping blade
and a blade mounting structure for controlling the protruding
amount of the blade edge. Accordingly, since the configuration of
the conventional wax remover for skis is complex and expensive due
to the adjustment of the wax scraping amount, the conventional wax
remover for skis is not suitable for use as the wax scraper for
surfboard, because the wax scraper for surfboard only has to scrape
off the wax.
[0010] Since the long hole for receiving the waste of wax is long
and thin, and the lid portion is covered over the main body, it is
not possible to see an inside of the main body through the long
hole. Therefore, there arises a problem in that how much wax has
been collected cannot be recognized. Additionally, there is
inconvenience in that the lid portion must be detached from the
main body to discharge the waste of wax.
[0011] In view of the above, an object of the present invention is
to provide a wax scraper for surfboard which has a simple structure
and can be produced at a low cost.
[0012] Another object of the present invention is to provide a wax
scraper for surfboard in which how much wax has been collected can
be known easily.
Means for Solving the Problems
[0013] To achieve the above object, a wax scraper for surfboard of
the present invention includes a collecting part for collecting
waste of wax and a scraping blade. The collecting part consists of
a bottom plate, a top plate, a pair of side plates, and a rear
plate. The collecting part has an inlet as an open face which
intersects with a scraping direction and lies at the front in the
scraping direction. The scraping blade is integrally formed with an
edge of the bottom plate for constituting the inlet, and used to
scrape a wax layer coated on a surfboard and feed the waste of
scraped wax to the collecting part.
[0014] It is preferable that an openable lid is integrally formed
with the top plate to allow a wax product for application to be
contained in the collecting part.
[0015] It is preferable that, a guide projection having a
positioning surface is formed at an edge of each of the pair of
side plates for constituting the inlet, and when the positioning
surface is made in contact with a surface of the wax layer, the
scraping blade is kept at a predetermined angle with respect to the
surface of the wax layer. Further, preferably, the scraping blade
has an upper blade surface and a lower blade surface, and the lower
blade surface is located on an extended line of the positioning
surface. Note that an angle made between the upper and lower blade
surfaces of the scraping blade is preferably in the range of
70.degree. to 80.degree..
[0016] It is preferable that a plurality of comb teeth for making
non-skid lines on the wax layer are integrally formed with an edge
of the top plate for constituting the inlet. Further, the rear
plate preferably has an arc-like curved surface. Furthermore, a cap
is preferably provided to cover the inlet.
Effect of the Invention
[0017] The collecting part of the present invention consists of the
bottom plate, the top plate, the pair of side plates, and the rear
plate. The collecting part has the inlet as the open face which
intersects with the scraping direction and lies at the front in the
scraping direction. According to the present invention, since the
scraping blade is integrally formed with the edge of the bottom
plate for constituting the inlet, the structure of the collecting
part is simple, and the collecting part can be produced at a low
cost.
[0018] Further, according to the present invention, since the inlet
as the open face of the collecting part is widely opened, how much
waste of wax is collected can be easily known by looking into the
inside of the collecting part through the inlet, and the waste of
wax can be easily discarded through the inlet.
[0019] Since the openable lid is provided to the top plate, the
collecting part can be used as the chamber for containing the wax
product when the wax scraper is not used. Further, since the
collecting part is exposed through the inlet by opening the
openable lid, it is also possible to discard the waste of wax
through the inlet. Furthermore, when part of or all of the
components of the collecting part are made of transparent material,
how much waste of wax is collected can be easily known.
[0020] Since the guide projection is provided to each of the pair
of the side plates, the scraping blade can be kept at a
predetermined angle with respect to the wax layer during the wax
scraping operation, and it is possible to scrape the wax layer
cleanly.
[0021] Since the comb teeth are formed at a position corresponding
to the scraping blade, it is possible to easily make non-skid lines
on the wax layer. Further, since the rear plate has an arc-like
curved surface so as to be in contact with user' s hand more
easily, the wax scraping operation can be readily performed.
Furthermore, when the cap is provided to cover the inlet of the
collecting part, it becomes possible to put the comb teeth out of
the way.

MODE FOR CARRYING OUT THE INVENTION
[0031] According to the present invention, as shown in FIGS. 1 and
2, a wax scraper 10 intended for surfboards includes a collecting
part 11, a scraping blade 12, guide projections 13a and 13b, comb
teeth 14, and an openable lid 15, which are integrally formed
together. The wax scraper 10 is made of ABS resin, for example,
through injection molding, and the respective components thereof
are integrally formed together. Therefore, the wax scraper 10 can
be produced at a low cost.
[0032] The collecting part 11 has a box shape including a bottom
plate 11a, a top plate 11b, side plates 11c and 11d, and a rear
plate 11e (see FIG. 3). Concretely, the collecting part 11 is a
rectangular parallelepiped in which each of the side plates 11c and
11d is a trapezoid. The width of each of the side plates 11c and
11d is gradually increased from the side of the bottom plate 11a to
the side of the top plate 11b. The collecting part 11 has an inlet
11f at the front side in a direction for scraping off the wax.
Spirally-rolled waste of scraped used wax is collected through the
inlet 11f into the collecting part 11. The waste of the wax has
viscosity similar to that of rubber clay, and adhered to the inside
of the collecting part 11.
[0033] As shown in FIG. 3, the scraping blade 12 is formed at the
front edge of the bottom plate 11a, which is in contact with the
inlet 11f, so as to be integral with the collecting part 11. The
scraping blade 12 has a lower blade surface 12a and an upper blade
surface 12b. An angle .alpha. made between the lower blade surface
12a and the upper blade surface 12b is preferably in the range of
70.degree. to 80.degree. for the purpose of scraping off the wax
more easily.
[0034] The guide projection 13a is provided at the front edge of
the side plate 11c, and the guide projection 13b is provided at the
front edge of the side plate 11d. The guide projections 13a and 13b
protrude forward with respect to the scraping blade 12. A
positioning surface 16a is formed at the front portion of the guide
projection 13a, and a positioning surface 16b is formed at the
front portion of the guide projection 13b. Between the scraping
blade 12 and an extended line of each of the positioning surfaces
16a and 16b is made a predetermined angle .beta.. Thus, when the
positioning surfaces 16a and 16b of the guide projections 13a and
13b are made in contact with a surface 22a of a wax layer 22 (see
FIG. 6), the scraping blade 12 is kept with a predetermined angle
.beta. with respect to the surface 22a of the wax layer 22. It is
to be noted that the angle .beta. made between the scraping blade
12 and the extended line of each of the positioning surfaces 16a
and 16b is preferably in the range of 40.degree. to 50.degree..
[0035] The lower blade surface 12a of the scraping blade 12 is on
the extended line of each of the positioning surfaces 16a and 16b
of the guide projections 13a and 13b. Thus, when the positioning
surfaces 16a and 16b are made in contact with the surface 22a of
the wax layer 22, the lower blade surface 12a of the scraping blade
12 comes in contact with the surface 22a of the wax layer 22.
[0036] The comb teeth 14 are configured to make lines on the wax
layer 22 for the purpose of increasing nonskid characteristics of a
surfboard. A plurality of the comb teeth 14 are arranged at regular
intervals at the front edge of the top plate 11b. The thickness of
each of the comb teeth 14 is the same as that of the top plate 11b.
Each of the comb teeth 14 has a width gradually becoming narrower
toward the front side so as to be shaped as a triangle.
[0037] As shown in FIG. 4, the collecting part 11 can be used as a
chamber for containing a wax product 20 when the wax scraper 10 is
not used. An aperture 17 is formed in the top plate 11b to take out
the wax product 20. The aperture 17 is normally covered with the
openable lid 15. The size of the collecting part 11 is defined in
accordance with the size of the wax product 20.
[0038] The openable lid 15 is integrally formed with the collecting
part 11 with use of a thin hinge portion 18 formed at a side in
contact with the aperture 17. The openable lid 15 is openable and
closable between an opening position (see FIG. 5) for exposing the
inside of the collecting part 11 through the aperture 17 and a
closing position (see FIG. 1) for covering the aperture 17.
Further, the openable lid 15 has engaging portions 19 formed at a
side opposing to the hinge portion 18. The engaging portions 19 are
engaged with a periphery of the aperture 17, so as to keep the
openable lid 15 at the closing position. When a user inserts
his/her fingernail into a dent 17a and lifts up the openable lid 15
from the closing position to the opening position, the engaging
portions 19 are elastically deformed and get over the periphery of
the aperture 17, and the engagement between the engaging portions
19 and the periphery of the aperture 17 is canceled. Thus, the
openable lid 15 is allowed to open.
[0039] Next, by referring to FIGS. 6 and 7, an operation of the wax
scraper 10 is explained. Before applying new wax to the surfboard,
it is necessary to remove old wax therefrom. The wax product 20 is
generally contained in the collecting part 11, and the openable lid
15 is opened so as to take out the wax product 20 through the
aperture 17.
[0040] The wax removing operation is started after closing the
openable lid 15. In the wax removing operation, the positioning
surface 16a of the guide projection 13a and the positioning surface
16b of the guide projection 13b are made in contact with the
surface 22a of the wax layer 22 coated on a surfboard 21, so as to
position the scraping blade 12 at a predetermined angle with
respect to the surface 22a. Then, the wax scraper 10 is moved in
parallel with the surfboard 21, while the scraping blade 12 is
pushed against the wax layer 22 such that the scraping blade 12
partially sinks in the wax layer 22. Thereby, the scraping blade 12
scrapes the wax layer 22. The scraped wax is spirally rolled, and
collected as waste of wax 23 through the inlet 11f into the
collecting part 11. Accordingly, the waste of wax 23 caused upon
the wax scraping operation is readily collected without being
splattered in the vicinity.
[0041] Since the inlet 11f is widely opened, how much waste of wax
23 is collected can be easily known by looking into the inside of
the collecting part 11 through the inlet 11f. When an appropriate
amount of the waste of wax 23 is accumulated in the collecting part
11, the openable lid 15 is opened and the waste of wax 23 is thrown
away through the aperture 17 to a trash box. Since the user only
has to discard the waste of wax 23 collected in the collecting part
11, the user does not get his/her hands dirty. Further, since the
collecting part 11 is almost entirely exposed by opening the
openable lid 15, it is possible to discard the waste of wax 23 and
clean the inside of the collecting part 11 more easily.
[0042] After removing the old wax, the user rubs the wax product 20
against the surfboard 21 to make a new wax layer. The rest of the
wax product 20 or unused purchased wax product 20 is put into the
collecting part 11 through the aperture 17 after opening the
openable lid 15. Once the wax product 20 is contained in the
collecting part 11, the openable lid 15 is closed. Thereby, the wax
product 20 is blocked by the base of the scraping blade 12, and
does not get out of the collecting part 11 through the inlet 11f.
Accordingly, it is possible to store the wax product 20 together
with the wax scraper 10 without losing the wax product 20.
[0043] For the purpose of increasing nonskid characteristics of the
surfboard 21 by making lines on the wax layer 22 coated on the
surfboard 21, as shown in FIG. 7, the wax scraper 10 is moved in
parallel with the surfboard 21 while the comb teeth 14 are pushed
against the wax layer 22. Since the comb teeth 14 protrude forward
with respect to the scraping blade 12 and the guide projections 13a
and 13b, the scraping blade 12 and the guide projections 13a and
13b never scratch the wax layer 22 at the time of making lines on
the wax layer 22 by the comb teeth 14.
[0044] Additionally, the wax scraper 10 may be provided with a cap
for covering the inlet 11f so as to put the comb teeth 14 out of
the way. In an example shown in FIG. 8, a box-shaped cap 24 is
provided to cover the collecting part 11 from the side of the inlet
11f. In this case, the cap 24 can cover and protect not only the
comb teeth 14 and the guide portions 13a and 13b but also the
scraping blade 12.
[0045] Although the collecting part 11 has a box shape in which the
top plate 11b is wider and longer than the bottom plate 11a and
each of the side plates 11c and 11d is a trapezoid in the above
embodiment, the present invention is not limited thereto. The
collecting part 11 may be in any shape as long as it can collect
the waste of wax. For example, the collecting part 11 may be a
rectangular parallelepiped, in which all of the top plate, bottom
plate, side plates, and rear plate are rectangles. Alternatively,
as shown in FIG. 9, the rear plate may have an arc-like curved
surface so as to form a protruding portion 25 protruding from the
rear side of the collecting part 11. In this case, since the
protruding portion 25 comes in contact with the user's hand at the
time of scraping off the wax, it becomes easier to push the wax
scraper 10.
[0046] In the case where the wax product 20 is not put into the
collecting part 11, it is unnecessary to provide the aperture 17 of
the top plate 11b and the openable lid 15. In this case, the waste
of scraped wax 23 is taken out from the collecting part 11 through
the inlet 11f with use of user's finger or a spatula.
[0047] Although ABS resin is taken as an example for the material
of the wax scraper in the above embodiment, the present invention
is not limited thereto. The wax scraper may be made of other
resins, or metal such as SUS. Additionally, transparent resin may
be used to make the openable lid 15 or the whole collecting part 11
transparent, such that the inside of the collecting part 11 can be
seen from outside.
