[Technical field]
[0001] The invention relates to ski pants provided with an edge guard.
Background Art
[0002] When gliding with skis, the edges of the skis often touch the bottoms of ski pants,
at times resulting in tearing of the bottoms. In order to prevent this, ski pants
are known in the prior art which comprise edge guards that protect the bottom sections
from the outer sides (PTLs 1 and 2, for example). In PTL 1, the edge guards are composed
of disposable parts that can be replaced when necessary. The edge guards are made
of a hard synthetic resin, such as hard urethane resin. In PTL 2, each of the edge
guards constructed in a half-folded manner by a member with a size suited for the
bottom opening of the inside bottom on the outer side of ski pants, is attached by
piercing through the fabric of the ski pants, with multiple protrusions extending
from the inside member of the edge guard and fitting with a receiving hole of the
outer side member, and it is anchored by a self-locking structure that forms a protrusion.
This edge guard is formed by a thin synthetic resin, and preferably a semi-rigid synthetic
resin.

Summary of the Invention
Technical Problem
[0004] The edge guard of the invention is not intended for general skiers (users). A conventional
edge guard employs a hard material, against potential tearing of ski pants on the
edges of skis due to error by the skier. The present invention, on the other hand,
is designed to counter phenomena that occur during gliding by advanced skiers such
as professional skiers, and it prevents rupture of the bottoms of ski pants caused
by strong impacts from the edges of skis, and also prevents ripping, since there is
no anchoring to the ski pants. As mentioned above, hard materials such as hard synthetic
resins or semi-rigid synthetic resins are used as edge guard materials. Edge guards
that are rigidly anchored can therefore constitute a hindrance to maneuvering by skiers,
for whom even a delay of less than 0.1 second is crucial during gliding with skis.
Moreover, if the edge guard is instead provided on the back fabric side of the ski
pants for reasons of design, this eliminates the effect of preventing the phenomenon
of tearing by the edges of skis.
Solution to Problem
[0005] In order to solve the aforementioned problems, the invention employs the following
construction.
Specifically, the invention relates to ski pants comprising an edge guard on the inner
thigh side of the bottom section between the bottom edge of the bottom and the area
below the knee, the edge guard being a shock absorbing body such as an elastic solid
or viscoelastic body. The bottom section is provided with shock absorbing body-attachment
means, to attach the shock absorbing body. The shock absorbing body-attachment means
is a shock absorbing body-housing section that houses the shock absorbing body inside
it. Preferably, the shock absorbing body-housing section allows removable of the shock
absorbing body. In addition, the shock absorbing body-housing section is provided
with fall-off preventing means that prevents the shock absorbing body from falling
off. The shock absorbing body-housing section may also be one that does not allow
removable of the shock absorbing body. The shock absorbing body-housing section is
further provided with water removable means that eliminates water that has entered
the shock absorbing body-housing section. Preferably, the water removable means is
a slit opening to allow removable of water, and is provided in the shock absorbing
body-housing section. The shock absorbing body-attachment means may also be bonding
means by which the shock absorbing body is bonded to the bottom section. The ski pants
of the invention are provided with a shock absorbing body on the back side of each
of the bottom sections. When the ski pants of the invention have bottom sections composed
of multiple different fabrics, they may be provided with a shock absorbing body between
the different fabrics, or between the different fabrics and on the back side of the
bottom sections.
Advantageous Effects of Invention
[0006] According to the invention, the edge guard is flexible so that maneuvering is not
impeded by the edge guard when the user is gliding on skis. Even if an edge guard
is provided on the back side of the bottom section or, when the bottom section is
composed of multiple different fabrics, between those different fabrics or between
the different fabrics and on the back sides of the bottom sections, it is possible
to prevent tearing of the ski pants by impact from the edges of skis.
Brief Description of Drawings
[0007]
Fig. 1 is an illustration showing ski pants according to an embodiment of the invention.
Fig. 2(A) is an illustration showing an edge guard provided in ski pants according
to an embodiment of the invention, and Fig. 2(B) is a cross-sectional view along A-A
in Fig. 2(A).
Description of Embodiments
[0008] Ski pants 1 according to an embodiment of the invention will now be described with
reference to Fig. 1 and Fig. 2. The ski pants 1 comprise edge guards 3 to prevent
tearing of the ski pants 1 by impact from the edges of skis. The "edge" of a ski is
an angle formed by the gliding surface of the ski and the normal to the gliding surface.
[0009] Fig. 1 is an illustration showing ski pants 1 according to this embodiment of the
invention. The ski pants 1 of this embodiment are especially suited for use by an
advanced skier. An "advanced skier" is a skier who participates in skiing athletic
competitions, including slalom skiing, super giant slalom skiing, and downhill skiing.
Thus, the ski pants 1 are most preferably used for skiing competition.
[0010] As shown in Fig. 1, the ski pants 1 are provided with edge guards 3 on the inner
thigh side of each bottom section 2 between the bottom edge of the bottom 4 of the
ski pants 1 and the area below the knee. The edge guard 3 is most preferably provided
near the bottom edge of the bottom 4, where the edge guard 3 is most likely to contact
with the ski pants 1. For an improved design property and to prevent impairing the
appearance of the ski pants 1 by the edge guard 3, the edge guard 3 is provided on
the back side (back fabric side) of the ski pants 1. Here, the fabric of the ski pants
1 that can be seen from the outer side of the ski pants 1 is referred to as the "front
fabric", and the fabric on the back side with respect to the front fabric is referred
to as the "back fabric".
[0011] The edge guard 3 is a shock absorbing body that absorbs impacts incurred when the
edge of a ski contacts the ski pants 1. The "shock absorbing body" is a material that
disperses and absorbs impact force by elastic deformation of the material, or by elastic
deformation and viscous flow of the material. Therefore, the shock absorbing body
is preferably an elastic solid or viscoelastic body. The shock absorbing body according
to this embodiment of the invention includes not only shock absorbing bodies composed
of shock absorption materials, but also shock absorbing bodies comprising both shock
absorbing materials and non-shock absorbing materials. Such shock absorbing bodies
do not include hard materials such as hard synthetic resins, for example hard urethane
resins, or semi-rigid synthetic resins. The shock absorbing body used in the edge
guard 3 is not particularly restricted so long as it absorbs impacts by the edges
of skis, and shock absorbing bodies include polyurethane-based resins, silicon-based
resins, acrylic-based resins, polyethylene-based resins, vinyl-based resins, styrene-based
resins, rubber, shock-absorbing gels, polypropylene-based resins, polyolefin-based
resins, polystyrene resins, and combinations of the foregoing. Particularly preferred
are shock-absorbing resins, shock-absorbing rubber and shock-absorbing gels, which
have excellent ability to disperse and absorb impact force through elastic deformation
and viscous flow.
[0012] The edge guard 3 provided on the back side of the ski pants 1 absorbs shearing stress
generated when the edge of a ski contacts with the ski pants 1, potentially tearing
the ski pants 1. During gliding on skis, therefore, it is possible to prevent contact
of the edges of the skis with the ski pants 1 from tearing the ski pants 1 by impact.
The present inventors have confirmed this by experimentation. The experimentation
that was conducted is described below.
[0013] An edge guard 3 provided on ski pants 1 according to an embodiment of the invention
will now be described in detail with reference to Fig. 2(A) and (B). Fig. 2(A) is
an illustration showing an edge guard 3 provided on ski pants 1 according to this
embodiment of the invention, and Fig. 2(B) is a cross-sectional view along A-A in
Fig. 2(A).
[0014] As shown in Fig. 2(A) and (B), a pocket is formed by a pocket fabric 51 and the back
fabric 22 of the ski pants 1, the rectangular edge guard 3 being housed in the pocket.
In order to prevent the edge guard 3 from falling from the pocket, a covering fabric
52 is provided to seal the opening of the pocket formed by the pocket fabric 51 and
the back fabric 22 of the ski pants 1. The pocket fabric 51 and covering fabric 52
are sewn onto the back fabric 22 of the ski pants 1.
[0015] As shown in Fig. 2(B), the covering fabric 52 partially overlaps with the pocket
fabric 51, and the edge guard 3 can be removed from the pocket while widening the
overlapping section and folding the edge guard 3, or the edge guard 3 can be housed
in the pocket through that section.
[0016] In order to prevent the edge guard 3 from moving in the pocket formed by the pocket
fabric 51 and the back fabric 22 of the ski pants 1, the pocket is constructed to
match the size of the edge guard 3. That is, the size of the edge guard 3 is a size
such that the edge guard 3 cannot move when the edge guard 3 is housed in the pocket.
[0017] The materials of the pocket fabric 51 and covering fabric 52 are selected from the
group consisting of mesh fabrics, woven fabrics, knitted fabrics, leather, and combinations
of the same, although there is no limitation to these. The material of the pocket
fabric 51 may be the same as or different from the material of the covering fabric
52. The materials of the pocket fabric 51 and covering fabric 52 may also be the same
as or different from the material of the ski pants 1.
[0018] As shown in Fig. 2(B), slit openings for water removable 53 are formed at the two
corners on the bottom edge of the bottom 4 side of the pocket fabric 51. These sections
of the pocket fabric 51 are not sewn, and snow that has entered into the pocket formed
by the pocket fabric 51 and the back fabric 22 of the ski pants 1 can be eliminated
as water through each slit opening for water removable 53.
Examples
Test to confirm prevention of tearing of ski pants
1. Test method
[0019]
- (1) A tester had both legs covered with ski pants, and then ski boots were worn on
both feet. The ski boots were covered by the ski pants from the shin section to the
bottom section. The ski pants had the following cross-sectional structure: front fabric,
filling cotton, back fabric.
- (2) At the overlapping section of the ski pants and ski boots, a shock absorbing body
pad made of soft urethane foam was attached to the back side of the right leg of the
ski pants. That is, the right leg of the ski pants had a structure in which a shock
absorbing body pad was sandwiched between the fabric of the ski pants and the ski
boots. No shock absorbing body pad was attached on the left leg of the ski pants.
- (3) The tester held one ski in both hands, and forcefully struck the ski boots on
both legs 40 times each with the edge of the ski, from above the ski pants. During
this time, the striking force of the edge of the ski against the ski pants was considerably
stronger than normally expected force.
- (4) The damage to the ski pants covering the ski boots was compared between the right
leg (with a shock absorbing body pad) and the left leg (without a shock absorbing
body pad).
2. Test results
(1) Right leg of ski pants (with shock absorbing body pad)
[0020] Scuffing produced by abrasion with the edge of the ski was observed. Impact-caused
cuts (holes) of approximately 3 mm were observed at two locations in the front fabric.
(2) Left leg of ski pants (without shock absorbing body pad)
[0021] Scuffing caused by abrasion with the edge of the ski was observed. Impact-caused
cuts (holes) of approximately 20 mm were observed at 12 locations in the front fabric.
Cuts of approximately 3 mm were observed at 9 locations. Of the 20 mm-sized cuts,
6 were found to be deep enough to reach the filling cotton section.
(3) Discussion
[0022] By comparing test results (1) and (2), it was confirmed that attaching an edge guard
3 to the back side of ski pants 1 has an effect of inhibiting contact of the edge
of skis with ski pants 1, and tearing of the ski pants 1. In this experiment, the
ski was impacted with a much stronger force than expected when the edge of a ski contacts
with ski pants during ski gliding, and therefore no tearing is to be expected even
when the edge of a ski contacts with ski pants during ski gliding.
[0023] The following functions and effects are exhibited by the ski pants 1 of the embodiment
described above.
(1) The edge guard 3 is a shock absorbing body composed of an elastic solid or viscoelastic
body. Since the edge guard 3 is therefore flexible, maneuvering is not impeded by
the edge guard 3 when the user is gliding on skis. The effect is particularly notable
for advanced skiers, for whom a delay of even less than 0.1 second is crucial during
gliding on skis.
[0024] (2) The edge guard 3 is housed in a pocket formed by the pocket fabric 51 and the
back fabric 22 of the ski pants 1. This allows the edge guard 3 to be easily attached
to the back side of the bottom section 2 of the ski pants 1. In addition, the front
side of the edge guard 3 is simply in contact with the back fabric 22 of the ski pants
1, without being anchored to it. This allows deformation of the front side of the
edge guard 3 without it being constrained by the back fabric 22, so that reduction
in the shock absorbing force of the edge guard caused by attachment of the edge guard
3 to the ski pants 1 can be minimized. Furthermore, since the front fabric 21 and
the edge guard 3 shift slightly when the edge of a ski has contacted the ski pants,
it is possible to further inhibit rupture of the ski pants caused by impact of the
edge guard.
[0025] (3) The edge guard 3 can be removed from the pocket formed by the pocket fabric 51
and the back fabric 22 of the ski pants 1. This allows the edge guard 3 to be replaced
in accordance with the skiing skill level and preference of the user.
[0026] (4) A covering fabric 52 is provided, to prevent falling out of the edge guard 3,
on the pocket formed by the pocket fabric 51 and the back fabric 22 of the ski pants
1. This can prevent the edge guard 3 from falling out while the user is gliding on
skis.
[0027] (5) Slit openings for water removable 53 are provided in the pocket formed by the
pocket fabric 51 and the back fabric 22 of the ski pants 1, through which water entering
the pocket is eliminated. This can prevent melted water from collecting in the pocket
even when snow has entered the pocket.
[0028] (6) The edge guard 3 is provided on the back side of the bottom section 2 of the
ski pants 1. This can prevent impairment of the appearance of the ski pants 1 by the
edge guard 3, while also avoiding tearing of the ski pants by the edges of skis. With
conventional hard edge guards, however, providing them on the back sides of bottom
sections 2 results in easy tearing of the ski pants by the edges of skis, similar
to how paper is easily cut on a hard cutter mat.
[0029] The ski pants 1 of the embodiment described above may also be modified, in the following
manner.
(1) So long as the edge guard 3 can be attached to the bottom section 2 of the ski
pants 1, the means of attachment is not limited to one that houses the edge guard
3 in the pocket formed by the pocket fabric 51 and the back fabric 22 of the ski pants
1. For example, bonding means such as a hook-and-loop fastener may be provided on
the front fabric 21 (see Fig. 2(B)) or the back fabric 22 of the ski pants 1 and on
the edge guard 3, the edge guard 3 being attached to the bottom section 2 of the ski
pants 1 by the bonding means. This also allows the edge guard 3 to be easily attached
to the bottom section 2 of the ski pants 1. Also, if the bonding means is one such
that the edge guard 3 is detachable, replacement of the edge guard 3 becomes possible.
[0030] Furthermore, if the front fabric 21 and edge guard 3 are slightly shifted when the
edge of a ski has contacted with ski pants, it will be possible to further inhibit
rupture of the ski pants by impact of the edge guard, and therefore in cases where
the attachment means is one such that the front fabric 21 and edge guard 3 are slightly
shifted when the edge of the ski has contacted with the ski pants, the attachment
means is not limited to one in which the edge guard 3 is housed in the pocket formed
by the pocket fabric 51 and the back fabric 22 of the ski pants 1.
[0031] (2) Housing of the edge guard 3 is not limited to housing in the pocket, so long
as the edge guard 3 can be housed. For example, the edge guard 3 on the back fabric
22 of the ski pants 1 may be covered by a prescribed fabric, the fabric being sewn
without open sections, for attachment of the edge guard 3. That is, the edge guard
may be housed and attached in a closed pouch that is unremovable.
[0032] (3) The fall-off preventing means provided by the covering fabric 52 is not limited
so long as it can prevent falling off of the edge guard from the pocket. For example,
a fastener may be provided on the opening of the pocket formed by the pocket fabric
51 and the back fabric 22 of the ski pants 1, to prevent the edge guard from falling
out from the pocket.
[0033] (4) So long as it is possible to eliminate water that has entered the pocket housing
the edge guard 3, the water removable means is not limited to water-eliminating slit
openings 53 provided in the pocket. For example, it may be means allowing water to
be eliminated by forming the pocket fabric 51 or covering fabric 52 from mesh fabric.
[0034] (5) The edge guard 3 was provided on the back side (back fabric 22 side) of the ski
pants 1, but it may instead be provided on the front side (front fabric 21 side) of
the ski pants 1. In this case as well, the edge guard 3 will be able to absorb impacts
from the edges of skis, and prevent tearing of the ski pants 1. When the ski pants
1 comprise multiple different fabrics (for example, the front fabric 21 and back fabric
22 in Fig. 2(B)), the edge guard 3 may be provided between the multiple different
fabrics (for example, between the front fabric 21 and back fabric 22 in Fig. 2(B)).
This can also prevent impairment of the appearance of the ski pants 1 by the edge
guard 3, while also avoiding tearing of the ski pants 1 by the edges of skis. An edge
guard may also be provided on the back side of the ski pants 1 and between the multiple
different fabrics. This can likewise prevent impairment of the appearance of the ski
pants 1 by the edge guard 3, while also avoiding tearing of the ski pants 1 by the
edges of skis.
[0035] (6) The shape of the edge guard 3 was rectangular, but there is no limitation to
this embodiment. For example, it may be circular, semicircular, triangular or the
like.
[0036] (7) The size of the edge guard 3 is not limited to the size in this embodiment. Most
notably, since the edge guard 3 of the ski pants for this embodiment of the invention
can reduce the degree of hindrance the user feels from the edge guard 3, it can therefore
be made larger. For example, the edge guard may be provided on half of the inner thigh
around the bottom section of the ski pants, the edge guard may be provided on half
of the bottom edge side of the bottom section, or the edge guard may be provided on
half of the inner thigh and half of the bottom edge side of the bottom. Since the
edge guard can thus be increased in size, it is possible to more reliably prevent
tearing of the bottom of ski pants when the edge of a ski contacts with the bottom.
[0037] (8) If the ski pants 1 of the invention are provided with an edge guard on the bottom
section, such as across roughly the entire bottom edge side of the bottom at the bottom
section, tearing of the ski pants 1 can be avoided even when the edge of the ski of
another person contacts with the ski pants 1. As explained above, the edge guard 3
can be increased in size in the ski pants 1 of the invention, thereby allowing this
modification to be made. In the case of snowboarding as well, since snowboarding pants
can also tear when contacted with the edge of the snowboard of another person, the
ski pants of the invention are suitable as pants for snowboarding.
[0038] The aforementioned embodiments may be applied in combination with one or more of
these modifications. The modifications may also be applied in combination with each
other.
[0039] The explanation provided above is merely for illustration, and the invention is in
no way restricted to the construction of the described embodiments.
