Description

  The present invention relates to a ski crampon used by being attached to a ski. More specifically, the present invention relates to a ski cramp that can reduce both ski slip and backward slip when climbing a snowy mountain.

  In mountain skiing and telemark skiing, when skiing up a snowy mountain, an anti-slip attachment is attached to the ski. As an attachment for preventing slipping, a ski seal described in Patent Document 1 and a ski cramp described in Patent Document 2 are known. The upper surface of the ski seal is a surface to be attached to the ski, and the lower surface is covered with hair extending toward the rear side. When the ski seal is affixed to the sole of the ski, the ski will not slide backwards when the ski seal is turned upside down, reducing ski slip to the rear when the skier puts his weight on the ski And climbing will be easier. The ski crampons are provided with two plate-like skid prevention blades arranged in parallel and a mounting plate spanned between the two skid prevention blades. The two skid prevention blades are mounted on the ski so as to protrude downward from both sides of the left and right edges of the ski. When the ski crampons are attached to the skis, the ski skis are reduced when the skier puts weight on the skis because the two skid prevention blades bite into the snow on both sides of the skis. , Climbing and skewing become easier.

  Further, Patent Document 3 describes a non-slip tool for causing a non-slip blade to protrude below the sole of the ski as an anti-slip attachment. This anti-skid tool has an upper member disposed on the upper side of the ski, and a lower member provided on the lower side of the ski and provided with a plate-like rear slip prevention blade. Further, the anti-skid tool is attached to the ski by fastening the upper member and the lower member with the ski sandwiched from above and below. When the anti-skid tool is installed, the anti-slip blade is arranged to extend in a direction perpendicular to the skiing direction under the sole of the ski, so that the skier does not slip when the skier puts weight on the ski. Bites into the snow, reducing the slip to the rear of the ski. Therefore, climbing is easier.

  When climbing a snowy mountain, the skier goes up with a ski sticker on the ski. In order to speed up climbing, skiers want to choose a route that goes straight to the summit unless there is a hazard. However, if the slope of the mountain surface becomes steep, it becomes difficult to climb linearly only with the grip force of the ski seal, so the skier is forced to skew zigzag. On steep slopes, skiers use ski seals and ski crampons together to prevent ski skidding. Here, skewing has a high risk of causing an avalanche, and the climbing speed also drops, so the skier wants to return to the route aiming straight at the summit. However, even if the ski seal and the conventional ski crampon are used in combination, the slip to the rear of the ski is not eliminated, and there is a problem that the desired route cannot be restored.

  Also, the snow surface often crusts in the snowy mountains during the remaining snow season. Under such circumstances, the frictional resistance between the snow surface and the ski seal is significantly reduced, and the grip force by the ski seal is weakened. Even in such cases, skiers use both ski seals and ski crampons, but ski slips and conventional ski cramps cannot be used to eliminate slipping backwards from the skis. There was a problem that it could not move forward and exhausted the physical strength.

  Here, in the case of performing skewing or in a situation where the snow surface is crusted, the above-described anti-skid tool having an anti-slip blade to the rear and a conventional ski cramp having an anti-skid blade are used in combination. It is possible. However, the work of attaching a plurality of attachments to each of a pair of skis in a snowy mountain is laborious and time-consuming. Further, if it is necessary to carry a plurality of attachments in addition to the ski seal when climbing, the load becomes bulky and heavy, which is inconvenient.

  In view of these points, an object of the present invention is to propose a ski cramp that can reduce ski skidding and rearward slipping when climbing a snowy mountain.

In order to solve the above problem, the ski crampons of the present invention are
A mounting plate attached to the surface of the ski,
A plate-like skid prevention blade extending from one end in the width direction of the mounting plate to the back side of the mounting plate and extending in the front-rear direction of the mounting plate;
A plate-shaped post-slip prevention blade extending from the inner surface of the skid prevention blade in a direction intersecting with the skid prevention blade;
And a gap for inserting a ski plate formed between the back surface of the mounting plate and an upper end surface of the rear slip prevention blade facing the back surface.

  When the ski crampons of the present invention are attached to the ski by inserting the ski into the gap for inserting the ski, the skid prevention blade protrudes downward from the side of one edge in the width direction of the ski and protrudes in the front-rear direction. The rear slip prevention blade is disposed so as to extend, and is disposed so as to intersect the skid prevention blade below the sole of the ski. Therefore, when the skier puts his / her weight on the ski, the anti-skid blade and the anti-slip blade that cross each other bite into the snow surface. As a result, it is possible to simultaneously reduce ski skidding and rearward slipping. In addition, since ski slip and backward slip can be reduced with one ski cramp, it is not necessary to attach a plurality of attachments to the ski, and the work of attaching the attachment to the ski in the mountains becomes easy. In addition, luggage can be reduced when climbing a snowy mountain.

  In the present invention, a plate-like second skid prevention blade extending from the other end in the width direction of the mounting plate to the back side of the mounting plate and extending in the front-rear direction of the mounting plate; A gap for a ski board insertion guide formed between an inner surface of the second skid prevention blade and a side end surface of the rear slip prevention blade facing the inner surface, It is desirable that the gap for inserting the skis is connected to the gap for inserting the skis. In this way, when the ski crampons are mounted on the ski, the second skid prevention blade is disposed so as to protrude downward from the side of one edge in the width direction of the ski and extend in the front-rear direction. . As a result, the skid ski is prevented from skidding by the two skid prevention blades, so that the skid skidding effect is improved. In addition, when the skier puts his weight on the ski, a consolidation layer in which snow particles are strongly bonded is formed inside the ski crampion surrounded by the ski and the two skid prevention blades, It will be in the state which digged into this compaction layer. As a result, the backslip prevention blade is prevented from moving to the rear side, so that the skier can securely grip the snow surface. Furthermore, when the ski crampon is attached to the ski, the ski can be inserted from the gap for the ski disc insertion guide into the gap for ski insertion, so that the ski crampon can be easily attached.

  In the present invention, it is preferable that the side end face of the rear slip prevention blade has a contour shape that moves away from the inner surface of the second skid prevention blade as it approaches the mounting plate. If it does in this way, it will become easy to insert a ski board in the gap for ski insertion. Further, since the ski can be inserted into the gap for inserting the ski even if the gap for inserting the ski is narrow, the anti-slip blade can be extended longer. Therefore, it is possible to improve the effect of preventing the ski crampons from slipping backward.

  The present invention has a plate-like second anti-skid blade extending from the other end in the width direction of the mounting plate to the back side of the mounting plate and extending in the front-rear direction of the mounting plate. The backslip prevention blade may be detachably mounted between the side slip prevention blade and the second side slip prevention blade. In this way, when the ski crampons are mounted on the ski, the second skid prevention blade is disposed so as to protrude downward from the side of one edge in the width direction of the ski and extend in the front-rear direction. . As a result, the skid ski is prevented from skidding by the two skid prevention blades, so that the skid skidding effect is improved. In addition, when the skier puts his weight on the ski, a consolidation layer in which snow particles are strongly bonded is formed inside the ski crampion surrounded by the ski and the two skid prevention blades, It will be in the state which digged into this compaction layer. As a result, the backslip prevention blade is prevented from moving to the rear side, so that the skier can securely grip the snow surface. Furthermore, since the rear slip prevention blade is configured to be long so as to be bridged between the side slip prevention blade and the second side slip prevention blade, an anti-slip effect to the rear is improved. Here, when the ski crampon is attached to the ski, after the ski is inserted into the gap for inserting the ski, the rear slip prevention blade may be bridged between the skid prevention blade and the second skid prevention blade. .

  In the present invention, in order to improve the effect of preventing rearward slipping, it is desirable that a plurality of the rear slip preventing blades are arranged at intervals in the front-rear direction of the mounting plate.

  Next, the present invention provides a ski crampon set, the ski crampons described above, a mounting plate fixing tool for mounting the mounting plate of the ski crampons on the surface of the ski plate, and the mounting plate fixing tool as a ski plate. And a fastening bolt that is fastened and fixed to the surface of the mounting plate, and an engaging portion that is detachably engaged with the mounting plate fixture is formed on the mounting plate. In this way, it is easy to detachably attach the ski crampon to the ski.

  When the ski crampons of the present invention are attached to the ski, the skid prevention blade is arranged so as to protrude downward from the side of one edge in the width direction of the ski and extend in the front-rear direction. It arrange | positions so that a skid prevention blade may be crossed under the sole of a board. Therefore, when the skier puts his / her weight on the ski, the anti-skid blade and the anti-slip blade that cross each other bite into the snow surface. As a result, it is possible to simultaneously reduce ski skidding and rearward slipping. In addition, since ski slip and backward slip can be reduced with one ski cramp, it is not necessary to attach a plurality of attachments to the ski, and the work of attaching the attachment to the ski in the mountains becomes easy. In addition, luggage can be reduced when climbing a snowy mountain.

(Installation of ski crampons on skis)
FIG. 3A is a perspective view of the ski crampons attached to the skis as seen from the front side of the skis, and FIG. 3B is a perspective view of the ski crampons attached to the skis as seen from the sole side of the skis. FIG. The ski crampons 2 are used by being attached to each of the pair of skis 40. Since the mounting of the ski crampons 2 on the skis 40 is performed in the same manner on each ski disc 40, the operation of mounting the ski crampons 2 on one ski 40 will be described and the operation of mounting on the other ski 40 will be described. Description is omitted.

  In this example, a telemark ski binding 41 is attached to the ski board 40. Further, between the front side fixing portion 42 and the rear side fixing portion 43 of the binding 41, the mounting plate fixing tool 30 is fixed in advance with the flange portion 35 facing upward. That is, the mounting plate fixing tool 30 is fastened and fixed to the ski plate 40 by the fastening bolts 31 to 33 that pass through the fastening bolt through holes 37 to 39 and are screwed into the ski plate 40. In a state where the mounting plate fixing tool 30 is fixed to the ski plate 40, the mounting plate 4 can be inserted from the front side along the surface 40 a of the ski 10 between the flange portion 35 and the surface 40 a of the ski 10. An insertion groove is formed.

  When the ski crampons 2 are attached to the ski board 40, first, as shown by the arrow in FIG. 2B, the ski board 40 is inserted into the ski insertion gap 27 via the ski board insertion guide gap 28. The ski crampons 2 are arranged between the front side fixing portion 42 of the binding 41 and the mounting plate fixture 30. Here, since the rectangular notch 8 is formed at the front end portion of the mounting plate 4, interference between the mounting plate 4 and the front fixing portion 42 is avoided. In a state where the ski plate 40 is inserted into the gap 27 for inserting the ski, the front surface 40a of the ski plate 40 abuts against the back surface 4a of the mounting plate 4, and the first skid prevention blade 5 is located on the side of one edge 40b. The second anti-skid blade 6 is positioned on the side of the other edge 40c, and the anti-slip blade 7 is positioned below the sole 40d.

  Next, the attachment portion 12 of the attachment plate 4 is detachably engaged with the attachment plate fixture 30. More specifically, while the leaf spring 11 is elastically deformed and the connecting portion 11c is pushed upward, the ski crampon 2 is slid rearward along the surface 40a of the ski 10 to form a semicircular cut in the mounting plate 4. The arc-shaped opening edge portion 10 a of the notch 10 is inserted into the insertion groove between the flange portion 35 and the ski 40. Thereby, the movement of the mounting plate 4 in the vertical direction and the width direction of the ski plate 40 is restricted.

  Thereafter, when the leaf spring 11 is returned to the original state, the leaf spring 11 is disposed at a position where the attachment plate 4 can be prevented from coming off from the insertion groove in the front-rear direction of the ski plate 40. As a result, the ski crampons 2 are attached to the ski board 40.

  Here, when the ski crampons 2 are loose in the width direction when the ski crampons 2 are first attached to the ski board 40, they are formed on the first skid prevention blade 5 and the second skid prevention blade 6. The pair of protrusions 14 are bent inward, and the tips of the pair of protrusions 14 are brought close to the left and right side surfaces of the ski 40 to prevent rattling.

  Note that the ski crampons 2 can be removed from the ski board 40 by performing the operation opposite to the attaching operation. In addition, the ski board 40 with the ski seal attached can be inserted into the gap 27 for inserting the ski, and the ski crampons 2 can be attached thereto. That is, the ski crampons 2 can be used in combination with a ski seal.

(Function and effect)
When the ski board 10 is inserted into the gap 27 for inserting the ski board and the ski crampons 2 are attached to the ski board 10, the first and second skid prevention blades 5 and 6 are located on the left and right edges 40b and 40c side of the ski board 40. The rear slip prevention blade 7 is disposed so as to extend in the direction perpendicular to the skiing direction below the sole of the ski 10. Therefore, if the ski mountain is climbed using the ski board 40 equipped with the ski crampons 2, when the skier puts his / her weight on the ski board 40, the ski skis 40 are prevented from skidding by the first and second skid prevention blades 5 and 6. The slip to the rear of the ski 40 is reduced by the rear slip prevention blade 7.

  When the skier puts his / her weight on the ski board 40, a consolidation layer in which snow particles are strongly bonded to each other inside the ski ski 2 surrounded by the ski board 40 and the first and second skid prevention blades 5 and 6. As a result, the backslip prevention blade 7 is in a state of biting into the compacted layer. As a result, the backward slip prevention blade 7 is prevented from moving to the rear side, so that the skier can securely grip the snow surface.

  Further, since the ski crampons 2 of the present example are provided with the first and second skid prevention blades 5 and 6 and the rear slip preventing blade 7, the ski skis 40 can be skid and moved backwards only by using the ski crampons 2. Slip can be reduced. Therefore, it is not necessary to attach an attachment other than the ski crampon 2 to the ski board 40, and the work of attaching the attachment to the ski board 40 in the mountains becomes easy. In addition, luggage can be reduced when climbing a snowy mountain. Furthermore, since the ski crampons 2 prevent slipping backward, a ski seal with a weak grip can be used when the ski crampons 2 and ski seals are used together. That is, as a ski seal, an inexpensive one such as a short ski seal or a narrow ski seal can be used, which is economical.

  Further, when the ski board 40 is inserted into the ski insertion gap 27 through the ski board insertion guide gap 28 and the attachment portion 12 is attached to the ski board 40, the mounting on the ski board 40 is completed. 2 is easy to install.

  Further, since the side end face 26 of the rear slip prevention blade 7 has a contour shape that moves away from the inner surface 6a of the second skid prevention blade 6 as it approaches the mounting plate 4, the ski plate 40 is inserted into the ski. Therefore, it is possible to avoid the ski board 40 from being damaged at the time of insertion. Further, if the side end face 26 has such a shape, the ski board 40 can be inserted into the ski insertion gap 27 even if the ski board insertion guide gap 28 is narrow. The blade 7 can be lengthened. Accordingly, it is possible to improve the backward slip prevention effect.

(Modification)
In the ski crampons 2 described above, the length dimensions in the front-rear direction of the first skid prevention blade 5 and the second skid prevention blade 6 are substantially the same as the length dimensions of the mounting plate 4. In order to improve the effect, the length dimension of the first skid prevention blade 5 and the second skid prevention blade 6 may be longer than the length dimension of the mounting plate 4.

  Further, in the ski crampons 2 described above, the rear slip prevention blade 7 is attached to the inner surface 5 a of the first skid prevention blade 5, but the rear slip prevention blade 7 is placed on the inner surface 6 a surface of the second skid prevention blade 6. The attachment and rear slip prevention blade 7 may extend from the second skid prevention blade 6 toward the first skid prevention blade 5.

  Further, the rear slip prevention blade body 20 of the rear slip prevention blade 7 extends so as to be orthogonal to the first skid prevention blade 5, but the second skid prevention blade 6 side may be inclined toward the front side, You may incline toward the rear side. Further, the blade portion 20a of the rear skid prevention blade 7 may protrude below the blade portions 13c, 13d, 13e of the first skid prevention blade 5 and the second skid prevention blade 6, and is located above. Also good. Further, in the above-described ski crampons 2, the rear slip prevention blade body 20 of the rear slip prevention blade 7 has a flat plate shape, but it is an arc-shaped plate that is slightly curved so that the lower end portion faces the rear side. Can do. Or it is good also as an arc-shaped board curved so that the 2nd skid prevention blade 6 side may go to a rear side.

  In the ski crampons 2 described above, the rear slip prevention blade 7 and the first skid prevention blade 5 are separate from each other, and the rear slip prevention blade 7 is fixed to the inner surface of the first skid prevention blade 5 with screws. It may be formed by bending a single plate member having a predetermined shape.

  In the ski crampons 2 described above, the number of rear slip prevention blades 7 is one. However, a plurality of rear slip prevention blades 7 may be arranged at intervals in the front-rear direction and attached to the first skid prevention blade 5. In this case, by making the length in the front-rear direction of the first skid prevention blade 5 longer than that of the mounting plate 4, a space for attaching the plurality of rear skid prevention blades 7 to the first skid prevention blade 5 is secured. Also good.

  Further, the second skid prevention blade 6 may be omitted from the ski crampons 2 described above.

  In addition, the mounting position of the ski crampons 2 on the ski board 40 may be on the front side or the rear side of the binding 41. Further, if the binding 41 and the mounting plate 4 do not interfere when the ski crampons 2 are mounted, the rectangular cutout portion 8 of the mounting plate 4 can be omitted.

  The ski crampons 2 are manufactured from a metal having strength and good workability. Examples of such metals include iron, aluminum, titanium, and alloys thereof.

  Further, the attachment plate fixing tool 30 and the attachment portion 12 formed on the attachment plate 4 are configuration examples, and the ski crampons 2 can be detachably attached to the ski plate 40 using other known configurations. Alternatively, a through hole for screwing may be formed in the attachment plate 4 as the attachment portion 12, and the ski crampons 2 may be attached to the ski plate 40 with screws. In this way, the ski crampons 2 can be fastened and fixed to the ski plate 40 without the mounting plate fixture 30.

(Another example of ski crampons)
FIG. 4 is a perspective view showing another example of the ski crampons. FIG. 5A is a side view of the ski crampon of this example, and FIG. 5B is a front view thereof. Since the ski crampons 2A of the present example have the same configuration as the ski crampons 2, common portions are denoted by the same reference numerals and description thereof is omitted. In the ski crampons 2A of this example, the rear slip prevention blade 7A is detachably mounted between the first side slip prevention blade 5A and the second side slip prevention blade 6A.

  As shown in FIGS. 4 and 5, the side-slip prevention blade body 13 </ b> A of the first side-slip prevention blade 5 </ b> A has a fixing bolt through hole 50, a first protrusion 51, and a second protrusion 52 from top to bottom. It is formed in order. The first protrusion 51 and the second protrusion 52 protrude from the inner surface of the first skid prevention blade 5. The first protrusion 51 is formed on the front side of the fixing bolt through hole 50, and the second protrusion 52 is formed on the rear side of the fixing bolt through hole 50. The second skid prevention blade 6A has the same configuration as the first skid prevention blade 5A.

  The rear slip prevention blade 7A includes a rectangular plate-like rear slip prevention blade body 20A that is long in the width direction, and a mounting cylinder 21A that extends along the upper end of the rear slip prevention blade body 20A.

  As shown by the arrow in FIG. 5A, the rear slip prevention blade 7A is arranged so that the attachment cylinder 21A passes between the first protrusion 51 and the second protrusion 52, and the first skid prevention blade 5 from below. And the second skid prevention blade 6. The mounting cylinder 21 </ b> A is arranged so as to be coaxial with the fixing bolt through hole 50. Thereafter, the fixing bolt 53 is passed through the fixing bolt through hole 50, the hollow portion of the mounting cylinder 21A, and the fixing bolt through hole 50 of the second skid prevention blade 6A from the first skid prevention blade 5 side. 2 A fixing nut 54 is fastened to the fixing bolt 53 on the side skid prevention blade 6 side. Accordingly, the rear slip prevention blade 7A is bridged between the first side slip prevention blade 5A and the second side slip prevention blade 6A. Further, a ski insertion gap 27 into which the ski plate 40 is inserted is formed between the second skid prevention blade 6 </ b> A and the mounting plate 4.

  When attaching the ski crampon 2 to the ski plate 40, the ski plate 40 is inserted into the gap for inserting the ski before the anti-slip blade 7A is bridged between the first skid prevention blade 5A and the second skid prevention blade 6A. 27, and the attachment portion 12 and the attachment plate fixture 30 are engaged. Thereafter, the backslip prevention blade 7A is bridged between the first skid prevention blade 5A and the second skid prevention blade 6A from the sole 40d side of the ski 40.

  When the snowy mountain is climbed using the ski board 40 equipped with the ski crampons 2A of the present example, the ski skis 40 are moved by the first and second skid prevention blades 6 in the same manner as when the ski crampons 2 are fitted to the ski board 40. Side slip is reduced. In addition, the slip to the rear of the ski 40 is reduced by the rear slip prevention blade 7A. Further, since the rear slip prevention blade 7A is configured to be extended between the first side slip prevention blade 5A and the second side slip prevention blade 6A, the rear slip prevention effect is high. Therefore, it is easier to climb and skew the snowy mountains.
