Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snow runner that allows a user to enjoy a refreshing run easily and further, so-called "wheelie run" in which the tail portion is used as a fulcrum and the tip is lifted with respect to the snow surface. Also, the present invention relates to a snow sliding tool that can easily perform so-called “fakey sliding”, which is sliding backwards.

The snow skiing equipment includes not only ordinary skis but also short-sized skis (skis having a total length of 1000 mm or less), snowboards, monoskis for people with physical disabilities, sleds, and the like.

2. Description of the Related Art Sports using the above-mentioned snow runners have been increasingly popular in recent years, and families can enjoy themselves on relatively easy courses, or they can challenge difficult courses to improve their skills. ing. And experienced skiers can enjoy new skiing by adding various techniques such as "Willie gliding" and "Fakey gliding", as it is not enough to glide down from the top of the mountain. Is coming.

[0004]

However, when performing "wheelie gliding" or "faky gliding", the conventional snow runner does not make any new work on the runner itself, so Even if he could improve his skiing skills with his skill and skill, he had a limit to enjoy new skiing, and it was difficult for beginners to perform these skiings themselves. Especially for short-sized skis and snowboards, unlike ordinary skis, even on skis with steep slopes or bumps, it is difficult for even an expert to apply the brakes, such as "wheelie sliding" and "faky sliding". Met. For example, in "wheelie skiing", a single-chip type model that has an upturn part where only the skid tob part is warped is generally used. Since the tail part was slippery, it was difficult to apply the brake and it was difficult to change the direction and rotate the subtlety. Also, in "Fakey gliding", a "twin chip" type is used that has an upturn part that is warped upward on both the top part and the tail part of the ski, but the tail part is lifted as a fulcrum. When the ski becomes unstable,
It was difficult for beginners, and it was difficult for even a skilled person to do it easily.

The present invention solves the above-mentioned problems, and even a beginner can perform a difficult technique, and even an expert can easily perform "wheelie sliding" on a steep slope or a hump-shaped snow surface. It is an object of the present invention to provide a snow runner that allows users to enjoy "Fakey gliding" and also to visually enjoy the gliders themselves and third parties, as well as to perform exhilarating glides.

[0006]

In order to solve the above-mentioned problems, the snow runner according to the present invention is constructed as follows. That is, the bottom surface is a sole surface, and the snow runner is provided with a runner body that is formed in a substantially plate-like shape in which a warp portion that faces upward is formed on the front side and a rear side, respectively. On the back warp,
It is characterized in that a projecting portion is provided which projects downward from the main body of the sliding equipment and which has a tip portion arranged above the lower horizontal surface of the sole surface.

It is more preferable that the tip of each of the protrusions is formed in a spherical shape.

More preferably, a guide channel for guiding the snow on the snow surface from the sole surface to the upper side of the sliding tool body is provided in the rear portion of the sliding tool body in front of the projecting portion. Anything that

[0009]

EFFECTS OF THE INVENTION In the snow runner according to the present invention, since the warp portion is formed at the front and rear of the runner body, and the rearward warp portion is provided with the downwardly projecting portion, the wheelie running is performed. When you do, even if it is a steep slope or a bumpy snow surface, you can let the protruding part bite into the snow surface,
You can easily apply the brakes to decelerate. Therefore, the projecting portion serves as a fulcrum to facilitate the direction change. Further, in the fake skiing, the projecting portion is arranged ahead of the skiing, but since snow can be released around the projecting portion, it is possible to facilitate the backward sliding. This makes it possible for beginners as well as beginners to easily perform difficult techniques and enjoy a bold run.

In addition, since the tip of the protruding portion is located above the sole surface, it is possible to perform a normal skiing without wheelie sliding without braking and without slowing down the skiing speed. You can enjoy skiing on the snow.

Further, according to the invention of claim 2, since the tip end portion of each projecting portion is formed into a spherical shape, snow can be smoothly released around the spherical projecting portion, and of course straight running is possible. That means you can enjoy a stable run even when you run diagonally or backward.

Further, according to the third aspect of the present invention, since the guide passage for guiding the snow upward from the sole side is provided at the rear portion of the main body of the sliding equipment, the snow is allowed to escape from the guide passage to the outside. Therefore, the snow pressure at the time of gliding is released, which facilitates gliding. Moreover, snow can be lifted up from the guide passage. As a result, the skier himself and a third person can enjoy it visually, and even beginners can enjoy a refreshing slide like a professional gliding and have a sliding feeling that has never been seen before.

Further, on the upper surface 14 of the plate body 10, a storage portion 17 is provided in a projecting position in front of the through hole 15a. Inside the storage portion 17, the ball 17b and the ball 17b are formed through the through hole. A ball plunger type detent means having a spring 17a for urging in the direction of 15a is incorporated. The spring 17a and the ball 17b are used for the plate body 10
It is covered with a cover 17c fixed to the upper surface 14 of the.
The cover 17c covers the upper surface side of a flange portion 62 of the tubular member 6 which will be described later so as to prevent the tubular member 6 from coming out upward.

In this embodiment, the plurality of small holes 16a formed in the warp portion 12a of the tail portion 12 are arranged in three rows behind the through hole 15a along the longitudinal direction of the plate body 10 as shown in FIG. , The four small holes 16a are arranged in the first row near the through hole 15a, and the three small holes 16a are arranged in the second row.
Are arranged, and two small holes 16a are arranged in the third row. The protruding member 8 inserted into each small hole 16a is shown in FIG.
As shown in FIG. 5, a spherical tip portion 8a arranged on the lower surface side of the warp portion 12a and a body portion 8b inserted into the small hole 16a.
And is formed to have a body portion 8 as shown in FIG.
b is tightened with the cap nut 9 while sandwiching the plate thickness (plate body 10) of the warp portion 12a, or is screwed into the screw portion 16b formed in the small hole 16a as shown in FIG. 5 (b). Alternatively, it is pressed into each small hole 16a.

Further, of the protruding members 8 inserted into the small holes 16a arranged in three rows, the tip head portion 8a of the protruding members 8 inserted into the small holes 16a in the first row near the through hole 15a.
Has a small spherical portion (that is, the height of the tip head portion from the sole surface 13a in the tail portion 12 is small), and the second row
Larger parts are formed in order along the third row. Moreover, 1
The tip head portion 8 of the protruding member 8 inserted into the small hole 16a in the row
a is arranged above the lower horizontal surface of the sole surface 13a.

As a result, when the top portion 11 is lifted with the projecting member 8 as a fulcrum to slide (wheelie slide),
The warp portion 12a of the tail portion 12 comes into contact with the snow surface, and the projecting member 8 bites into the snow surface to perform a braking action, so that a slight direction change or rotation can be easily performed.

As shown in FIG. 6A, the protruding member 8 may be a protruding portion 8A which is directly formed integrally with the warp portion 12a of the tail portion 12, or as shown in FIG. 6B. Then, the seal member 8C having the protruding portion 8B is attached to the warp portion 1
You may make it adhere | attach on the sole surface 13a of 2a entirely. In this case, the protrusions 8A and 8B are arranged in three rows in the same manner as in the above-described embodiment, and four, three, and two are arranged from the row close to the through hole 15a, respectively, and the small holes 16a are not formed. May be.

Further, in order to easily perform the "wheelie sliding" with the ski 1, if the projecting member 8 projects so as to bite into the snow surface when the main plate body 10 is obliquely lifted, the brake is applied. Since it can be easily made, for example, one spherical object, hemispherical object, angular object, etc. may be projected on the lower surface side of the warp part 12a of the tail part 12, and a large number of linear materials such as brushes are arranged. However, the shape and configuration thereof are not limited.

As another form of the ski 1, although not shown, the protrusion 8 can be provided on the tail portion 12 of the ski 1 without the cylindrical member 6.
The form of the protruding member 8 is as described above. However, it is desirable to provide the tubular member 6 in order to release the snow pressure at the time of gliding.

The cylindrical member 6 is an example of an extension cylindrical portion, and as shown in FIGS. 2 to 4, it is constructed by using a resin (for example, acrylic) cylindrical body having an inclined axis. Main body 61, and the main body 61 is connected and fixed to the main body 6
1 and a flange portion 62 that projects from the outer peripheral surface on the lower end side in the radial direction of the main body portion 61 over the entire circumference.
The flange portion 62 is slidably fitted onto the upper end of the guide cylinder 15 and is covered by a cover 17c extending from the storage portion 17 so as to be a center of rotation in the vertical direction along the plate thickness direction of the plate body 10. As a result, rotation is allowed to prevent the collar portion 62 from coming off upward. Further, ratchet teeth 63 which can engage with the balls 17b are provided on the outer peripheral surface of the collar portion 62 at substantially equal intervals.

The tubular member 6 has a recess 6 between any two adjacent ratchet teeth 63 in the collar 62.
4, the ball 17 urged by the spring 17a
Since b is fitted, the careless rotation of the tubular member 6 is suppressed. Then, as shown in FIG. 4, the substantially linear extension flow path 65 formed in the internal space of the main body 61 of the tubular member 6 communicates with the main flow path 30 of the guide flow path 20, and The path 30 is extended above the plate body 10.

In the embodiment, since the main body 61 is in a state where its axis is inclined, the extension flow path 6
The path of 5 is inclined with respect to the plate thickness direction of the plate body 10. Further, since the tubular member 6 is rotatably held with respect to the plate body 10 by using the cover 17c and as a central axis of rotation of the plate body 10 in the vertical direction which is the thickness direction of the plate body 10, The inclination direction of the path of the extension flow path 65 can be appropriately changed according to the rotation applied to the member 6. In addition,
With the rotation of the tubular member 6, the ball 17b is disengaged from the recess 64 between the two adjacent ratchet teeth 63, and then is fitted into the new recess 64.

Next, the ski 1 constructed as described above
The usage state of will be described with reference to FIGS.

First, as shown in FIG. 7, in the present ski 1 as well, as in the case of a normal ski, the sole surface 13a of the main plate body 10 may be brought into contact with the snow surface S to slide on the snow surface S. it can. At this time, in the plurality of protruding members 8 arranged on the tail portion 12 of the plate body 10, the tail portion 12 has the sole surface 13
has a warp portion 12a directed upward with respect to the horizontal portion of a,
Since it is located above the horizontal portion of the sole surface 13a, it does not contact the snow surface S.

As shown in FIG. 8, during this gliding, the top portion 11 of the plate body 10 is placed on the snow surface S with the plurality of projecting members 8 arranged on the tail portion 12 of the plate body 10 as fulcrums. On the other hand, when it is lifted in an inclined manner, that is, when the wheelie is slid, the warp portion 12a of the tail portion 12 comes into contact with the snow surface S and the projection member 8 sinks into the snow surface S, and the snow on the snow surface is cut. The snow scraped by the projecting member 8 is guided from the sole surface 13a side of the plate body 10 to the guide passage 20.
Continuously flowing into the guide channel 2
The main body flow passage 30 and the extension flow passage 65 of 0 are sequentially passed, and the upper side of the plate body 10 is continuously jetted.

In the case of the Willy gliding, the skiing speed of the ski is momentarily reduced by the projection member 8 sinking into the snow surface S. This allows the planer to
It becomes easy to slightly change the direction of the ski 1 and rotate it.

Further, when the wheelie gliding state is entered, since the tip heads 8a of the projecting members 8 arranged in three rows are formed larger as they are arranged on the rear row side, the lifting angle of the top portion 11 is increased. The protruding member 8 can be submerged in the snow surface S without leaning too much.

Further, the skier can easily rotate the ski 1 to perform fakey skiing in which the ski is slid in the back direction. As shown in FIG. 9, in the fake skiing, the tail portion 12 is located in the front in the traveling direction and the top portion 11 is located in the rear, so that the protruding member 8 arranged in the tail portion 12 is arranged in the front. It will be.

When skiing a fake, the snow on the snow surface S not stepped on the ski 1 first comes into contact with the projecting member 8 and is stepped on the horizontal surface of the sole surface 13a in order. When the snow comes into contact with the protruding member 8, the gliding speed is reduced from the normal gliding speed.
Since snow can smoothly pass between the projecting members 8 formed in a spherical shape, the projecting members 8 do not impede the fake skiing.

In the above embodiment, the extension flow path 6
Since 5 is opened above the ski 1 for the right leg with an inclination to the right side, the snow passing through the guide flow path 20 is diagonally upper right above the ski 1 for the right leg. Is injected into. Then, in the left ski 1 forming a pair with the ski for the right leg, the extension flow paths 65 are symmetrically arranged.
Since the ski is opened to the left above the ski 1, the snow is spouted diagonally upward on both the left and right sides of the skier.

In the present embodiment, the tubular member forms the extension flow path 65 in an inclined state with respect to the plate thickness direction of the plate body 10, and the tubular member 6 has the plate thickness of the plate body 10. It is rotatable as a rotation center axis along the direction. Therefore, when the tubular member 6 is rotated in a desired direction by a predetermined rotation amount, the inclination direction of the extension flow path 65 is rotated in the desired direction. For example, the extension flow path 65 may be replaced by the plate body 1
Above 0, the snow can be jetted toward the rear side of the ski 1 by inclining it toward the rear of the tail portion 12 of the ski body 10.

As described above, the ski 1 of the embodiment is
The top portion 11 and the tail portion 12 of the plate body 10 are respectively formed with warp portions 11a and 12a, and the warp portion 12 of the tail portion 12 is formed.
Since a plurality of downwardly projecting members 8 are provided in a, it is possible to make the projecting members 8 bite into the snow surface during the sliding of the wheelie and to form a steep slope or a bumpy snow surface. Even so, the brake can be easily applied to decelerate. Therefore, the plurality of projecting members 8 serve as a fulcrum to facilitate direction change and rotation. Further, in the fake skiing, the plurality of projecting members 8 are arranged ahead of the skiing, but since snow can be released between the plurality of projecting members 8, it is possible to facilitate the backward sliding. . As a result, beginners as well as beginners can easily perform difficult techniques and can enjoy a bold run.

Moreover, since the tip head portion 8a of the projecting member 8 is located above the sole surface 13a, in normal skiing without wheelie skiing, the skiing speed is not reduced and the skiing speed is not reduced in normal skiing. You can
You can enjoy snow gliding according to the condition of each gliding.

Further, since the tip end head portion 8a of each projecting member 8 is formed in a spherical shape, the snow can be smoothly released along the spherical surface of the projecting member 8 and not only straight running but also slanting. Stable gliding can be carried out even when going down a row or backwards.

Further, since the guide passage 20 for guiding the snow toward the upper surface 14 from the sole surface 13a side is provided at the rear portion of the plate body 10, the snow can be released from the guide passage 20 to the outside. As a result, the snow pressure at the time of gliding is released, which facilitates gliding. Moreover, by gliding the snow from the guide flow path 20 during the run, the runner himself and a third person can enjoy it visually, and even beginners can enjoy the refreshing slide like a professional run. It is possible to have a sliding feeling that has never been seen before.
