Description

  The present invention relates to a stock pole.

  Ski poles play an important role in both alpine skiing and Nordic skiing to improve skiing efficiency by balancing and taking rhythm work.

  By the way, in order to make a turn in an alpine ski (so-called normal ski before 2000), a turning operation is particularly necessary among the ski operations (loading, squatting, and turning). In other words, at the connecting part of the turn, twist the outer leg of the previous turn (for example, the right leg at the end of the left turn) and twist the outer leg of the next turn (for example, the left leg at the start of the right turn). It was necessary to start the turn.

  In order to assist such movement, the stock pole is parallel to the center axis of the trunk (the trunk axis 20, arm 21, stock pole 22 and snow surface 23 when the rider is seen from the front. The center axis 20 and the stock pole 22 are parallel trapezoidal images (see Fig. 12) or tilted inward with respect to the center axis of the trunk (center axis of the trunk when the rider is seen from the front) An image of making an isosceles triangle with 20, arm 21 and stock pole 22. See Fig. 13) It was thought that it was desirable to strike (this makes it easier to twist the lower limbs and upper limbs, and twisting back and twisting is efficient) Well done.)

  Therefore, as a method of pushing the stock pole, for example, as shown in Patent Document 1, a pushing method in which the wrist is directed in the traveling direction (the bean bone of the wrist joint is directed in the traveling direction) is suitable. And the shape in which the action point is on the little finger side was the mainstream (the grip of the stock pole is mainly grasped by the little finger, ring finger, and thumb).

  By the way, since 2000, with the advent of carving skis, the skiing operation for making a turn has greatly reduced the need for a turning operation compared to the normal skiing era, and a large squaring operation with twisting is also possible. It became unnecessary. That is, twisting back and twisting at the connecting portion of the turn is not necessary.

  Specifically, in the case of carving skis, the corners of the outer rotation of the previous turn (for example, the right foot at the end of the left turn) are removed at the connecting part of the turn to bring the skiing edge closer to the snow surface. In this way, the turn can be started by moving the center of gravity to the inside of the next turn so that the outer leg of the rotation (for example, the left leg when starting the right turn) is in contact with the snow surface.

  In order to assist such movement, the stock pole should be tilted outward with respect to the center axis of the trunk (the center axis 20 of the trunk, the pole 22 and the snow as viewed from the front of the rider). An image of a two-sided triangle in which the center axis 20 of the trunk and the snow surface 23 sandwich a right angle with the surface 23, and a stock pole 22 forming a right-angled triangle with an oblique side (see Fig. 14). Yes.

  For this reason, it is considered appropriate to push the pole on the snow surface (with the bean bone of the wrist joint facing the snow surface) as a way to push the pole in carving skis. There is a need for a stock pole having a grip of the shape.

  An embodiment of the present invention which is considered to be suitable will be briefly described with reference to the drawings showing the operation of the present invention.

  When pole work is performed with the gripping part 3 held by hand, for example, when the pole 2 is moved forward, the thumb is larger than when the pole 2 is moved forward with the little finger side (little finger and ring finger) as a fulcrum. When the palm is pushed forward with the side (thumb and forefinger engaged with the thumb forefinger abutting portion 4) as a fulcrum, the wrist, lower arm, upper arm, etc. are moved less The pole 2 can be moved forward by movement.

  Accordingly, the stock pole 1 according to the present invention is provided with the thumb forefinger abutting portion 4 having a small diameter on the upper side of the gripping portion 3, so that the pole 2 is minimized with the thumb as a fulcrum. For example, when the stock pole 1 is struck with a carving ski, the movement of the wrist or the like is minimal, and the body axis is shaken even when the turn is performed continuously. It becomes difficult and it becomes possible to repeat the turn efficiently.

  The stock pole according to the present invention can be used not only for alpine skiing but also for nordic skiing and nordic walking. In this case as well, pole work can be performed easily.

  Specific embodiments of the present invention will be described with reference to the drawings.

  This embodiment is a stock pole 1 in which a grip 14 is provided on the top of a pole 2, and the grip 14 is provided with a grip portion 3 having a small diameter with respect to the top portion 5. Is provided with a concave thumb forefinger abutting portion 4 for abutting the thumb and forefinger of the hand gripping the gripping portion 3, and the circumference of the thumb forefinger abutting portion 4 is an average of the gripping portion 3. It is set to 70 to 92% with respect to the circumference.

  Each part will be specifically described.

  As shown in FIGS. 1 to 4, the grip 14 having the top portion 5 and the grip portion 3 is formed by molding an appropriate synthetic resin member (thermoplastic), and inside the upper portion of the pole 2. The hole (illustration omitted) which inserts is formed. The pole 2 and the grip 14 are connected and fixed by, for example, screwing a connecting bolt that passes through an insertion hole provided in the upper end surface of the top 5 into a screw hole at the upper end of the pole 2. Note that the stock poles in each figure are for the right hand, and illustration of a strap normally provided on the grip 14 is omitted.

  Further, in the present embodiment, the grip portion 3 of the grip 14 includes the surface portion 12 with which each finger or palm abutted by the groove 11 abuts and the other core portion 13 (where the hole is provided). It is composed of members of different colors.

  A concave thumb forefinger abutting portion 4 is annularly provided on the upper portion of the grip portion 3 so as to surround the outer periphery thereof.

  Further, the peripheral diameter of the center position of the thumb forefinger abutting portion 4 of the gripping portion 3 is set to be small so that the thumb and the index finger can be easily grasped. Specifically, it is set to 70 to 92% with respect to the average circumference of the grip portion 3. This is a numerical value determined by repeated experiments. If it is less than 70%, it is too thin to make a smooth pole work, and if it exceeds 92%, it is too thick and there is an appropriate gripping force in the pole work at the thumb fulcrum. I can't show it.

  In addition, a protrusion located between the index finger and the middle finger of the hand gripping the gripping part 3 (below the index finger) is located at the front side of the gripping part 3 and below the thumb index finger contact part 4. 10 is provided. Further, a convex portion 9 for guiding the position of the thumb is provided on the inner side of the grip portion 3 (left side for right hand and right side for left hand). The projection 10 and the convex portion 9 and the thumb forefinger abutting portion 4 provide a state in which the gripping portion 3 is stably grasped by the thumb and the index finger, and good pole work is possible.

  In addition, the lower part of the gripping part 3 is provided with a little finger abutting part 7 on which the little finger of the hand gripping the gripping part 3 abuts, and the palm of the hand gripping the gripping part 3 is abutted on. A palm abutting portion 6 is provided at a site (central portion of the gripping portion 3). In addition, it is formed in the smooth surface which does not have an unevenness | corrugation from the protrusion part 10 to the little finger contact part 7 in the front side of the holding part 3. FIG.

  The palm contact portion 6 is configured to bend in a convex shape toward the palm side. Further, the palm abutting portion 6 is provided with a raised portion 8 protruding outward (on the right side for the right hand and on the left side for the left hand). The maximum circumference of the palm contact portion 6 is set to 105% or less with respect to the average circumference of the gripping portion 3 and 117% or more with respect to the circumference of the center position of the thumb index finger contact portion 4. This is also a numerical value determined by repeated experiments. If it is less than 105% with respect to the average circumference of the gripping part 3, the gripping is too thin and the gripping is not stable. If it exceeds 117% of the circumference, the pole work which is too thick to be pushed out with the palm cannot be properly performed.

  Further, the maximum circumferential diameter position of the palm contact portion 6 has a length L from the center position of the little finger contact portion 7 to the upper side and from the center position of the little finger contact portion 7 to the center position of the thumb index finger contact portion 4. It is provided at a position of 35% or more. After all, this value is also a value determined by repeated experiments. When the length is less than 35% of the length L, the fit to the palm is impaired, and the pole work pushed out with the palm cannot be appropriately performed.

  By the palm contact portion 6 and the convex portion 8 that are curved in a convex shape on the palm side, the grip portion 3 that is stably grasped by the thumb and the index finger can be lightly pushed out by the palm, such as a wrist joint It is possible to perform pole work with an extremely light motion without moving almost.

  The grip 14 is provided on the pole 2 in a state where the axis Q of the grip 14 (grip part 3) is inclined forward by 4 ° or more with respect to the axis P of the pole 2. Experiments have confirmed that if the angle is less than 4 °, the pole stone protrusion cannot be pushed to an appropriate position. Specifically, the hole is formed so as to incline forward by a predetermined angle with respect to the axis P of the grip 14.

  Further, the length N from the center position of the little finger contact portion 7 to the intersection position of the axis P of the grip 14 and the axis Q of the pole 2 is determined from the center position of the little finger contact portion 7 to the thumb index finger contact portion 4. The fitting hole is configured to be below the position of 55% of the length L to the center position. This is because if it exceeds 55% of the length L, the pole stone protrusion cannot be pushed to an appropriate position.

  Here, in this embodiment, the average circumference of the gripping portion 3 is the circumference of the center position of the thumb forefinger contact portion 4 (the circumference of the AA position in FIG. 2) and the maximum of the palm contact portion 6. The average value of the peripheral diameter (the peripheral diameter at the CC position in FIG. 2) and the peripheral diameter at the center position of the little finger contact portion 7 (the peripheral diameter at the BB position in FIG. 2) is used. Further, the center position of the thumb forefinger contact portion 4 is the intermediate position in the longitudinal direction of the thumb index finger contact portion 4, and the center position of the little finger contact portion 7 is the intermediate position in the longitudinal direction of the little finger contact portion 7.

  FIG. 11 shows a dimension example of the comparative example and the example. In FIG. 11, the thumb portion indicates the thumb index finger contact portion, the little finger portion indicates the little finger contact portion, and the palm portion indicates the palm contact portion.

  The comparative example 1 illustrated in FIGS. 5 to 7 is an example in which the fulcrum at the time of pole work is not particularly conscious, and the comparative example 2 illustrated in FIGS. 8 to 10 is an example in which the operation is easy with the little finger side as a fulcrum. It is.

  Comparative Examples 1 and 2 also have grips 14 'and 14 "(top portions 5' and 5", gripping portions 3 'and so on provided on the top of the poles 2' and 2 "constituting the stock poles 1 'and 1". 3 ″), the thumb forefinger abutting portion 4 ′ · 4 ″ is the portion where the thumb abuts, the little finger abutting portion 7 ′ · 7 ″ is the portion where the little finger abuts, and the palm abutting portion 6 ′ is the portion where the palm abuts.・ 6 ”.

  The length M from the center position of the little finger contact portion 7 ', 7 "to the center position of the palm contact portion 6', 6" in the longitudinal direction of the grip 14 ', 14 "is 14 mm in Comparative Example 1. The comparative example 2 is 24 mm, and the embodiment is 30 mm. From the center position of the little finger contact portion 7 '· 7 ", the axes Q' · Q" of the grips 14 '· 14 "and the shafts of the poles 2' · 2" The length N up to the intersection with the centers P ′ and P ″ is 41.94 mm in Comparative Example 1, 47.73 mm in Comparative Example 2, and 36.94 mm in the Example.

  Here, in the present embodiment, the circumference of the center position of the thumb forefinger contact portion 4 is 87.59% of the average circumference of the gripping portion 3, and the maximum circumference of the palm contact portion 6 is the gripping portion. 103.41% with respect to the average circumference of 3 and 118.06% with respect to the circumference of the center position of the thumb index finger contact portion 4, and the maximum circumference position of the palm contact portion 6 is the center position of the little finger contact portion 7. It is 41.48% of the length from the center position of the little finger contact portion 7 to the center position of the thumb forefinger contact portion 4 from the upper side to the upper side, and the axis Q of the grip 14 from the center position of the little finger contact portion 7. The length N from the center position of the little finger contact portion 7 to the center position of the thumb forefinger contact portion 4 is 51.07% of the length N from the center position of the pole 2 to the axis P of the pole 2. Within the above numerical range.

  On the other hand, in Comparative Example 1, the circumference of the center position of the thumb forefinger contact portion 4 ′ is 93.75% of the average circumference of the grip portion 3 ′, and the maximum circumference of the palm contact portion 6 ′ is the grip. 108.71% with respect to the average circumference of the holding part 3 ′ and 115.95% with respect to the circumference of the center position of the thumb index finger contact part 4 ′, and the maximum circumference of the palm contact part 6 ′ is the little finger contact. It is 19.44% of the length from the center position of the small finger contact portion 7 'to the center position of the thumb forefinger thumb forefinger contact portion 4' from the center position of the portion 7 ', and the little finger contact portion The length N from the center position of 7 'to the intersection position of the axis Q' of the grip 14 'and the axis P' of the pole 2 'is determined from the center position of the little finger contact part 7' to the thumb index finger contact part 4 It is 58.25% of the length L to the center position of 'and both are outside the above numerical range.

  In Comparative Example 2, the circumference of the center position of the thumb index finger contact portion 4 ″ is 98.87% with respect to the average circumference of the grip portion 3 ″, and the maximum circumference of the palm contact portion 6 ″ is the grip. 110.34% of the average circumference of the holding part 3 "and 111.60% of the circumference of the center position of the thumb index finger contact part 4", the maximum circumference of the palm contact part 6 "is the little finger contact 33.3% of the length from the center position of the little finger contact portion 7 ″ to the center position of the thumb forefinger thumb forefinger contact portion 4 ″ from the center position of the portion 7 ″, and the little finger contact portion The length N from the center position of 7 ″ to the intersection position of the axis Q ″ of the grip 14 ″ and the axis P ″ of the pole 2 ″ is from the center position of the little finger contact portion 7 ″ to the thumb index finger contact portion 4 ”Is 66.29% of the length L to the center position of“, ”which is outside the above numerical range.

  In the case of the configuration as in Comparative Examples 1 and 2 that does not have the configuration of the present embodiment, when the thumb and index finger are gripped, the thumb and index finger can be stably held by the thumb and index finger due to the large diameter of the thumb index finger contact portion. Can not be performed, or there is no palm abutment that curves in a convex shape on the palm side, pushing out by the palm does not work well, and pole work is performed with very light movement without moving the wrist joint etc. I have confirmed that I can not.

  Since the present embodiment is configured as described above, when the pole work is performed in a state where the grip portion 3 is gripped by hand, for example, when the pole 2 is moved forward, the little finger side (little finger and ring finger) is used as a fulcrum. Compared to the case where the pole 2 is moved forward, the case where the palm is pushed forward with the thumb side (thumb and forefinger engaged with the thumb forefinger abutting portion 4) as a fulcrum is more effective for the wrist, lower arm and upper arm. The pole 2 can be moved forward with less movement of the wrist or the like without greatly moving the joint.

  Therefore, for example, when the stock pole 1 is struck with a so-called carving ski having a side cut (arc constituting the side surface of the ski) of less than R20 (radius 20 m) (for example, radius 15 m), the movement of the wrist and the like is minimized. When the turn is performed continuously, the body axis becomes difficult to shake and the turn can be repeated efficiently.

  By the way, when a stock pole is struck by skiing, there is a physiological characteristic that "even if only the wrist is moved, the elbow joint which is one of the trunk side joints is affected by the wrist joint movement". Shaking of the body axis when pushing the stock pole is often caused by the movement of the shoulder joint. In skiing exercises, it is often the case that the fall of the body pole caused by the movement of the shoulder joints is caused by the movement of the stock pole, which is the connection between the right (left) turn and the left (right) turn. .

  Actually, in normal skiing, when you turn the wrist with the wrist in the direction of travel where the lower limbs and upper limbs are easy to twist (turn the bean bone of the wrist joint in the direction of travel) Because the wrist joint and elbow joint move simultaneously, the shoulder joint on the trunk side of the wrist moves, and as a result, there are many beginners who fall due to body axis blurring.

  In ski school training, detailed training was given on the position and posture of wearing snow stock.

  In the present embodiment, even an beginner is able to move the elbow joint affected by the wrist joint movement, but there is almost no influence on the shoulder joint, so the body axis blur is extremely reduced. The skiing feeling test was conducted on the slopes by several testers from the skiing experience level to the qualified person level, but there was no faller and a smooth turn exercise was possible.

  Note that the present invention can be used not only for alpine skiing but also for nordic skiing and nordic walking, and in this case as well, pole work can be performed easily.

  Therefore, in this embodiment, pole work can be performed with less wrist movement, and for example, when turning a carving ski, it is possible to prevent blurring of the body axis and to enable efficient start of the turn. It will be excellent.
