DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a ski, and an object of the present invention is to provide a ski that has good vibration damping properties and is easy to maneuver.

(Prior art) Conventionally, vibrations caused by the impact applied to the skis from the snow surface during skiing have reduced the ability of the skis to reliably grip the snow surface, which has led to the skis' edging and rotational performance. This hindered the operation and made it difficult to operate.

Therefore, recently, in order to dampen these vibrations faster and improve the maneuverability of skis,
Various methods are known. For example, as shown in FIG. 5, there is a ski 10 in which a vibration damping member 16 made of a viscoelastic material is disposed in the longitudinal direction of the core material 15, and as shown in FIG. It is generally known that a buffer plate 26 made of an elastic material such as rubber or plastic is disposed below the fastener mounting area.

Furthermore, Japanese Utility Model Publication No. 55-49816 discloses a ski in which vibrations are damped by providing a metal plate and a recessed part and forming a rubber layer on the recessed part.

(Problems to be Solved by the Invention) These skis had the following problems. That is, in the ski shown in FIG. 5, since the vibration damping member 16 is disposed only in a part of the ski in the width direction, there is a problem that vibrations caused by impacts from the sliding surface cannot be completely covered. .

In addition, in the ski shown in FIG. 6, the buffer plate 2
6 extends to the side wall of the ski, so that the impact transmitted from the bottom surface can be absorbed over the entire width of the ski. However, in order for the buffer plate to fully exhibit its buffering effect, it is necessary to maintain a certain thickness of the buffer plate, but as shown in Figure 6, even if the thickness of the buffer plate is thin and almost uniform, the impact is large. In this case, there were problems such as the shock absorbing plate being severely compressed and unable to exhibit its vibration damping properties.

Furthermore, in skis in which a flat rubber layer is formed by providing recesses in the metal plate, it is possible to attenuate vibrations with the rubber layer, but this only mainly damps the vibrations generated in the metal plate. It was not possible to dampen the vibrations of the ski itself.

As shown in FIG. 1, in a ski consisting of at least an upper surface component 2, a lower surface component 3, a core member 4, etc., the core member 4 is applied to a required portion of the upper surface, lower surface, or both sides from both ends. A concave portion 5 having a cross section with a peak at the center of the width is provided, a vibration absorbing member 6 having a convex shape that matches the concave portion 5 is disposed, and an upper surface component member is adhered to the upper surface of the vibration absorbing member 6, and a lower surface component member is adhered to the lower surface thereof. This is a ski 1 .

The chevron-shaped concave portion 5 is formed in an inverted chevron shape or a regular chevron shape at a predetermined portion in the longitudinal direction of the core member 4, with the apex extending from both side ends 4a to the central portion 4b. It has a chevron shape that matches the chevron-shaped recess 5 and is configured to sufficiently exhibit a vibration absorption effect.

In addition, when disposing the vibration absorbing member 6 in the core member, the material for molding the vibration absorbing member is placed in a mold together with other ski constituent members during the manufacturing stage of the ski of the present invention. After being inserted into the mold, the mold can be compressed, and the constituent members can be integrally formed by bonding them together with an adhesive or the like.

(Function) In the ski of the present invention, since the inverted chevron-shaped or right chevron-shaped concave portions are provided from both ends of the core member 4 so that the apex is at the center, both sides of the core member serve as ribs to increase the length. The weight of the concave portion can be reduced without reducing the bending strength in both the direction and the width direction. and,
Since the chevron-shaped vibration absorbing member that matches the chevron-shaped recess is disposed, vibrations generated during skiing can be absorbed by the entire width of the ski. In particular, since the vibration-absorbing member is chevron-shaped, vibration waves propagating to the ski are diffused in the chevron-shaped shape, and the vibrations are quickly attenuated, thereby improving the maneuverability of the ski.

(Other Embodiments) As another embodiment of the present invention, as shown in FIGS. 3 and 4, a chevron-shaped vibration absorbing member 6 is attached to the front and rear contact points of the ski and the lower surface of the center member in the binding area. By arranging the vibration damping effect, the vibration damping effect is increased.

In addition, as the material for forming the chevron-shaped vibration absorbing member, materials with elastomer properties such as soft rubber, foamed plastic, and other plastics may be used, or these may be made of fiber-reinforced plastic materials such as glass, carbon, Kevlar, and boron. By using a material surrounded by , it can be placed in a mold together with other structural members, and can be compressed and adhesively molded at the same time.

(Effects of the Invention) As described above, in the ski of the present invention, a concave portion having a cross section with a vertex at the center width from both ends of the core member 4 is provided, and a concave portion having a convex shape is disposed in the concave portion. At the same time, by surrounding the vibration absorbing member with fiber-reinforced resin or embedding a weight made of thin metal wire or plate inside, the rigidity of the ski itself can be adjusted and at the same time vibration damping properties can be improved. It is also possible to adjust the moment of inertia by means of a weight embedded within the vibration absorbing member.

In addition, the shape of the chevron-shaped recess in which the vibration absorbing member is disposed in the core member is formed into a chevron-shaped cross section with the apex at the center of the width from both ends of the core member, so that the vibration-absorbing shape of the chevron conforms to the shape of the chevron-shaped recess. By arranging the members, both sides of the core member become ribs to maintain the deflection strength of the ski, and the vibration of the ski due to impact during skiing is absorbed because the vibration absorbing member has a chevron shape. This increases the ratio, reduces the burden on the skier's legs, and results in a ski with less fatigue.
