Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a member for partially enhancing the rigidity of a ski in the vicinity of a ski center.

[0002]

[Prior art]

 Thickening the ski is the simplest and most effective way to increase the rigidity of the ski, but if it is partially done, the shape will become discontinuous, which will hinder the installation of the binding. Therefore, as shown in FIG. 3, for example, the aluminum plate-shaped member 2 is attached to the upper surface of the ski center (hereinafter, simply referred to as the center) 22 of the ski 20 via the plate-shaped hard rubber 10. By doing so, a rigidity-enhancing member 1a devised so as to absorb the vibration of the ski 20 generated at the time of sliding and to increase the rigidity near the center 22 is known.

[0003]

[Problems to be solved by the device]

 However, in the conventional rigidity-enhancing member 1a having the above-described structure, the rear end 5 of the plate member 2 arranged toward the tail side 21 of the ski 20 is immovably attached to the ski 20 by the screw 3a, On the side of the front end 7 that is arranged toward the top side 23 of the ski 20, there are a long hole 11 provided in this portion so as to be elongated in the front-rear direction, and a screw hole 13 provided in a substantially J-shaped mounting member 12. By being screwed through the screw 3c to the ski 20, the ski 20 is mounted slidably in the front-rear direction. Therefore, when the ski 20 bends by receiving an external force, the plate member of the rigidity enhancing member 1a is bent. The shear stress received by 2 is almost zero due to the sliding of the plate member 2 and the ski 20.

Therefore, the total rigidity of the ski 20 in the vicinity of the center 22 is obtained by simply adding the rigidity of the plate member 2 to the rigidity of the ski 20, and the increase in rigidity cannot be expected so much. On the other hand, in terms of weight, the weight of the hard rubber 10 is also added, for example, the weight becomes 550 g, which is a drawback that it cannot be used by skiers with weak leg strength.

The mounting member 12 is immovably attached to the upper surface of the ski 20 by the screw 3c. Further, 14 is a hard rubber which is fitted into the elongated hole 11 and serves as a shock absorbing material.

[0006] Therefore, a proposal for a lightweight member for strengthening rigidity, which can remarkably increase rigidity, has been expected.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention has a plate-shaped member attached to the upper surface of a ski center of a ski, and a mounting means for immovably mounting the substantially central portion and the ski tail side of the plate-shaped member to the ski. It is intended to provide a rigidity enhancing member for a ski, which comprises an attaching means for slidably attaching the ski top side of the plate member to the ski.

[0008]

[Action]

 The approximately central portion and the tail side of the plate-shaped member are immovably attached to the ski center upper surface of the ski, and the top side is slidably attached, so that the approximately central portion of the ski center and the member of the present invention are provided. The rigidity of the ski increases only while the rear end is attached, and this part is less likely to deform.

Therefore, in the ski having the rigidity-enhancing member for a ski according to the present invention attached thereto, the deformation of the part mainly catching the snow surface from the ski center to the tail is small, so that the ski boot is attached to this part. If set, the force applied to the sole of the ski shoe is smoothly transmitted to the snow surface, and the operability is remarkably improved.

[0010]

【Example】

 An embodiment of the present invention will be described below in more detail with reference to FIGS. 1 and 2. In order to facilitate understanding, in these figures, the parts having the same functions as those shown in FIG. 3 are designated by the same reference numerals, and the description thereof is omitted to the extent that it does not hinder the understanding of the present invention. .

As shown in FIGS. 1 and 2, reference numeral 1 in the drawings denotes a rigidity-enhancing member according to the present invention, and like the conventional rigidity-enhancing member 1a shown in FIG. It is attached to the surface and is used to strengthen the rigidity of this part.

The rigidity enhancing member 1 illustrated here is a plate member 2 made of, for example, aluminum, and screws 3 a, 3 b, 3 c for attaching the plate member 2 to the upper surface of the center 22 of the ski 20 and a substantially J-shape. And the sliding mounting member 4 of FIG.

The plate-shaped member 2 has a flat lower surface so that it can be attached to the flat upper surface of the ski 20, and a flat upper surface except both ends in the front-rear direction so that the binding 30 can be attached. The substantially central portion 6 and the rear end 5 which are formed flat are immovably attached to the upper surface of the ski 20 by the screws 3b and 3a, and the front end 7 is attached by the sliding attachment member 4 to the ski. It is designed to be slidably mounted on the upper surface of 20.

The sliding attachment member 4 is attached immovably to the upper surface of the ski 20 by means of a screw 3c, and a gap 8 formed between the sliding attachment member 4 and the upper surface of the ski 20. The thin front end 7 of the plate-like member 2 is slidably inserted in the middle and set.

In the rigidity-enhancing member 1 having the above-described structure, the plate-shaped member 2 has a flat upper surface, so that the binding 30 can be easily attached. Further, the ski 20 which receives an external force is hard to be deformed between the screws 3a and 3b to which the plate-like member 2 is immovably attached, but is easily deformed at a portion between the screws 3b and 3c. .

That is, since the deformation of the portion of the ski 20 from the center 22 to the tail that mainly catches the snow surface is small, the force applied to the sole of the ski shoe 31 is smoothly applied to the snow surface. The operability is remarkably improved.

Since the present invention is not limited to the above-mentioned embodiments, various modifications can be made in accordance with the spirit of the scope of claims for utility model registration.

For example, a plurality of screw holes are provided at different positions so that the mounting position by the screw 3b can be adjusted in the front-rear direction, and the rigidity can be freely selected according to the weight and leg strength of the skier. Is also possible. Also, if the mounting position can be adjusted in the width direction, it is possible to make a difference in torsional rigidity between the valley foot side and the mountain foot side.

[Effect of device]

 As is clear from the above description, the present invention has a plate-shaped member attached to the upper surface of the ski center of the ski, and a mounting means for immovably mounting the substantially central portion and the ski tail side of the plate-shaped member to the ski. Since this is a rigidity enhancing member for a ski, which comprises a mounting means for slidably mounting the ski top side of the plate-shaped member to the ski, the ski having the rigidity enhancing member for a ski according to the present invention, The rigidity of the part that mainly catches the snow surface from the ski center to the tail is increased, making it difficult to deform. Therefore, if a ski shoe is set in this portion, the force applied to the sole of the ski shoe is smoothly transmitted to the snow surface, and the operability is remarkably improved.

Further, since the rubber used in the conventional technique is not used, the weight increase is about 350 to 400 g, and even a skier with weak leg strength can easily operate it.
