Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carving ski compatible stock and a cover for snow contact with a grip portion for the carving ski compatible stock.

[0002]

BACKGROUND OF THE INVENTION Generally, in a ski, the width of a skiing surface is narrow at a center portion and a width of a top and a tail portion is wide. Attention has been paid to a type called a carving ski having a deeply formed side curve. And
In such a carving ski with a deep side curve,
Compared to conventional skis where the side curve is not so deep, the top and tail are more likely to penetrate the snow surface, so even beginners who have poor distribution of the load applied to both skis during skiing and poor sense of the load transfer While the turn can be easily performed, an advanced person who has a feeling of appropriate load distribution and load movement can perform a so-called sharp turn with less deviation.

[0003] By the way, such carving skis, especially for advanced skiers, have an extreme curve type in which the side curve is extremely deep so that a sharper turn can be performed. There is. In the case of the extreme curve type carving skis, when the skid that fully utilizes the characteristics of the carving skis is achieved by fully utilizing the deep side curves, the outward inclination of the conventional normal skis is required. Gliding technology cannot sufficiently withstand centrifugal force, so it is necessary to have a glide technology that inclines the body axis more inwardly. The skiing technique is akin to a carving turn on a snowboard.

[0004] Here, the skier usually slides with the stock in his hand, but if the hand with this stock is to touch the snow, it must be done with the finger holding the grip. It is easy to cause injuries and is not preferable for safety.
Therefore, when making such an extreme curve turn, the skier slides without holding the stock as in the case of snowboarding, wears snowboarding gloves, etc., and touches the snow on the palm side. I have.

[0005]

By the way, ski slopes generally have a large number of slopes with different slopes and the like according to their skiing skill levels, from beginners to experts, and the slopes between the slopes are wide. Since the vehicle is communicated through a narrow passageway or the like, the vehicle does not always make an extreme curve turn in which the hand touches the snow during the gliding, but also glides with the gliding technology based on the conventional outward inclination posture.

[0006] Therefore, when sliding on a slope or a communication passage that is not suitable for the turn of the extreme curve, it becomes difficult to slide without the stock, and if the user slides with the stock, the turn of the extreme curve is attempted. There was a problem that it would be a hindrance when doing so.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a bank sensor by making a hand holding a stock snow-contact even when making an extreme curve turn by carving skis. To provide a carving ski compatible stock that can slide safely while fulfilling the role of a grip, and a grip part snow cover that can be attached to an existing stock and easily changed to a carving ski compatible stock. It is in.

A shell for snow contact curved so as to cover the shell is provided, and the outer surface of the shell for snow contact is formed as a smooth sliding surface.

According to a second aspect of the present invention, in the configuration of the second aspect, the shaft is laterally separated from a skier's body at a position below a lower end of the snow contact cover. And at the same time, it is bent rearward, and bent back forward at a position above the basket mounting position.

According to a third aspect of the present invention, there is provided a snow contact cover for a carving ski-compatible stock, wherein a snow contact cover attached to cover a grip provided at an upper end of a shaft of the ski stock is gripped by a finger at a front portion of the grip. A shell which is curved so as to cover the holding portion with a space for gripping the outer surface and has an outer surface formed on a smooth sliding surface without irregularities, and a rearward portion from an upper end of the shell to cover an upper end surface of the grip. An upper fixing portion which is integrally formed to extend and is integrally fastened and fixed to an upper end surface of the grip by a screw for connecting the grip to the shaft; and And a lower fixing portion composed of a boss portion fitted to the shaft portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 shows an embodiment of a carving ski-compatible stock according to the present invention, wherein FIG. 1 (a) is a side view and FIG. 1 (b) is a rear view. FIG. 1 shows the right arm of a pair of left and right symmetrical stocks. As shown in FIG. 1, the carving ski-compatible stock 2 includes a shaft 4, a grip 6 provided at an upper end of the shaft, a basket 8 provided below the shaft 4, and a snow contact covering the front portion of the grip 6. And the main cover 12.

In the embodiment shown, the grip 6 is a general conventional type formed in a closed cylindrical shape, and is fitted and mounted axially outside the upper end of the shaft 4 to penetrate the lid. The strap 10 is fastened and fixed via a fixing bush embedded inside the upper end of the shaft 4, and the strap 10 is also fastened and fixed together by the screw.

As shown in FIGS. 2 (a) to 2 (e), the snow cover 12 has a three-dimensionally curved shell 14 and an upper fixing portion 16 integrally formed on the upper end of the shell 4.
The lower fixing portion 18 is formed integrally with the lower end portion, and is integrally formed of a resin material. 2, (a) is a left side view, (b) is a front view, (c) is a rear view, (d) is a top view, and (e) is a right side view of a lower fixing portion.

The shell 14 is formed so as to cover a portion to be gripped mainly by fingers at the front part of the grip 6 and is formed in a three-dimensionally curved bowl shape with a space for gripping the upper and lower sides. Are wide, and the width of the central part is narrowed to be slightly narrower. Then, in side view, the shell 14 is curved in an arch shape, and the widthwise central portion of the upper end portion extends rearward to reach and cover the upper end surface of the grip 6, and the portion becomes the upper fixing portion 16, Screw 2 for fixing the grip
0 and are fixedly connected to the upper end surface of the grip 6. The lower end of the shell 14 extends downward of the grip 6, and is connected and fixed to the shaft 4 at the lower portion. That is, at the lower end of the shell 14, a boss portion 22 that fits into the shaft 4 as the lower fixing portion 18 is integrally formed to extend downward. The boss portion 22 has a slit 24 along the axial direction on the rear side, and a pair of flanges 26 projecting rearward from the slit groove 24. Then, the lower end of the shell 14 is firmly fixedly connected to the shaft 4 by tightening the boss 22 with a fixing bolt 28 provided on the flange 26. Flattened side walls 30, 30 are integrally formed on both sides of the narrowed central portion of the shell 14, and the side walls 30, 30 function as reinforcing ribs to improve the strength of the shell 14. I have. Further, the outer surface of the shell 14 is formed as a smooth surface having no protrusions or depressions and a smooth surface having a small coefficient of friction.

On the other hand, the shaft 4 is bent at three points in a three-dimensional direction as shown in FIG. That is, FIG. 3 shows the shaft 4 of FIG. 1 alone, and FIG. 3 (a) is a side view and FIG. 3 (b) is a rear view. It has a second inflection point 34 and a third inflection point 36, and when viewed from the back side with the center of the longitudinal center thereof being vertical, the skier is above the first inflection point. Towards the side that separates,
That is, in the case of the stock 2 for the right arm in the illustrated example, the stock is bent rightward, and its position is set to an angle in the vicinity of immediately below the lower end of the snow contact cover 12 attached to the upper end of the shaft 4. About 3 degrees (Fig. 3
(B)). In addition, the second bending point 34 is set at a position of about 2/7 from the upper end with respect to the entire length of the shaft 4, and is bent about 7 degrees backward toward the rear.
The bending point 36 is set at a position about 1/6 from the lower end of the shaft, and near the upper end of the basket 8 attached to the relevant portion, the angle is set toward the front in the opposite direction to the second bending point 34. About 3 degrees (Fig. 3
(A)). The basket 8 has a triangular pyramid shape.

In the carving ski-compatible stock 2 of the present invention having the above-described structure, the front part of the grip 6 is covered with the snow contact cover 12, so that when the skier makes a turn in an extreme curve, he / she slides. When the posture is set to the inward inclining posture and the body axis approaches the slope, the shell 14 of the snow contact cover 12 is brought into contact with the snow to press the grip 6 of the stock 2 against the snow surface. Since the shell 14 can be protected and the outer surface of the shell 14 is formed as a smooth sliding surface without curved irregularities, the shell 14 in contact with the snow may be caught by the irregularities on the snow surface and the like, and the upper body may be out of balance. Therefore, while holding the stock 2, the user slides his hand through the snow contact cover 12 while actively sliding on the snow surface while performing the role of a bank sensor. Bets can be, and can be prevented as much as possible from snowflakes from entering the inside by the side wall 30 provided on the shell 14 parts on both sides of Seyyukiyo cover 12.

At this time, the shaft 4 of the stock 2 is bent outward at the first bending point 32 immediately below the grip 6, so that the snow contact cover 12 can be contacted slightly forward of the side of the body. Even if this is done, the rear end side of the shaft 4 opens outward so as to separate from the body, and it is difficult for the shaft 4 to hinder the sliding. Further, since the shaft 4 is bent rearward at the second bending point 34, the rear end side of the shaft is separated upward from the snow surface in a state where the snow contact cover 12 is in contact with the snow, and the basket 4 8 is also formed in the shape of a triangular pyramid, so that it is hardly affected by snow surface resistance, and therefore, the sliding balance in the front-rear direction is hardly disturbed.

Therefore, according to the carving ski-compatible stock 2, turns of the extreme curve can be safely performed without difficulty while holding the stock. In addition, in the case where the turn of the extreme curve is not performed, it is possible to easily slide while using the stock by the conventional sliding technique based on the outward inclination posture. At this time, the shaft 4
Is bent back forward at a third bending point 36 just above the basket 8, so that when the tip of the stock pierces the snow surface, the angle between the tip and the grip 6 in the front-rear direction is They are almost the same, and the operability of the stock work is hardly impaired.

The snow contact cover 12 has its upper fixing portion 16 fixed to the upper end surface of the grip 6 by fastening together with a screw 20 for fixing the grip 6 to the shaft 4, and the lower fixing portion 18 has its lower fixing portion 18 fixed thereto. Since the boss is fitted and fixed to the shaft 4 below the grip 6, the boss can be easily attached at the same time as the grip 6 is attached. The existing stock can be easily changed to a carving ski compatible type.

The snow contact cover 12 is desirably made of a fiber-reinforced resin material reinforced with fibers such as carbon or Kevlar in order to secure the strength and rigidity. Also,
The basket 8 is not limited to the triangular pyramid shape shown in the illustrated example, and may be a spherical shape or the like that is hard to catch on the snow surface.

[0022]

As described in detail above, according to the carving ski compatible stock according to the first aspect of the present invention, the front part of the grip is covered with the snow-contact cover, so that the skier is excited. When making a stream curve turn, when the sliding posture is inwardly inclined and the body axis is brought close to the slope, the shell of the snow contact cover is brought into contact with the snow and the grip part of the stock is pressed against the snow surface Even if it does so, the finger can be protected, and the outer surface of the shell is formed with a curved smooth running surface, so the shell that has come into contact with the snow will be caught by the unevenness of the snow surface and the upper body will be out of balance. Therefore, while holding the stock, it is possible to slide while actively sliding on the snow surface through the snow contact cover, while performing the role of a bank sensor. That.

According to the carving ski compatible stock according to the second aspect of the present invention, since the shaft is further bent outward at the first bending point near the portion directly below the grip, the snow contact cover can be attached to the body. Even when the shaft touches the snow a little in front of the side, the rear end of the shaft tends to open outward so as to separate from the body, so that it is possible to prevent the shaft from hindering the running as much as possible.

Also, since the shaft is bent rearward at the second bending point, the rear end of the shaft tends to move upward away from the snow surface with the snow contact cover in contact with the snow. This makes it difficult to receive the sheet resistance, so that it is possible to prevent the sliding balance in the longitudinal direction from being disturbed as much as possible.

Further, since the shaft is bent back forward at the third bending point near the upper portion of the basket, the tip of the shaft is bent back forward. Are almost the same, so that the operability of the stock work can be prevented from being impaired as much as possible.

According to the grip cover for a carving ski compatible stock according to claim 3 of the present invention, the upper fixing portion is jointly fixed to the upper end surface of the grip by screwing together the screw for fixing the grip to the shaft. However, since the lower fixing part has a structure in which the boss part is fitted and fixed to the shaft part below the grip, it can be easily attached at the same time when the grip is mounted, and once removed from the existing stock, the grip is remounted. Therefore, the existing stock can be easily changed to a carving ski compatible type.
