DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a ski plate.

[0002]

2. Description of the Related Art Conventionally, as a ski having a fixed plate plate, for example, Japanese Patent Application Laid-Open No. 3-133472 "Ski" is known. That is, in the “ski”, “a ski comprising a ski body and a slab attached to an upper binding portion of the ski body, the forefoot slab attached to the upper part of the ski body has a coating having bending rigidity. A ski comprising a layer and an underlying intermediate layer of lower bending stiffness, wherein the absorbing slider is placed in a binding near the upper surface of the ski body. "

[0003] When an integrated object composed of a coating layer having a bending rigidity on the upper surface and an elastic body made of rubber or the like on the lower surface is attached to a solid, the vibration damping effect is remarkably improved. Measures are known (for example, "Noise Control" Vol.N issued by the Japan Noise Control Engineering Society.

By the way, when the braking plate is attached to the ski plate portion, the load on the skier's foot is reduced due to vibration. However, as shown in FIG. 10, when the top and heel bindings (metal fittings) of the ski 52 are respectively fixed to one braking plate 51, a fixing screw for fixing the top binding 53 to the braking plate,
Since the fixing screws of the heel binding 54 are completely fixed to the plate plate 51, three-point bending fatigue of two-point support occurs during skiing. That is, the ski boot is attached to the brake plate before and after the ski boot by the top binding and the heel binding, and the ski runs in contact with the brake plate on the bottom surface of the ski boot.

[0005] For this reason, large strain is likely to be generated at the center of the brake plate, which is the ground contact portion of the ski boot between the top binding 53 and the heel binding 54. Then, a large force is generated on the brake plate attached to the ski, causing a motion different from that of the ski, and the brake plate 51 is provided between the heel binding screw and the top binding screw.
Peeling occurs and the brake plate 51 itself breaks.

In order to prevent the occurrence of distortion, it is necessary to completely bond the brake plate and the ski body with a strong adhesive, but in this case, the braking force is affected, and the ski body is affected. Since another reinforcing plate is bonded, the rigidity of the portion becomes too strong, and the ski becomes completely different from the original balance, and there is a problem that the properties of the ski are significantly impaired.

[0007]

Means for Solving the Problems The present invention provides

[0008] The top binding attachment portion to which the top binding is attached and the heel binding attachment portion to which the heel binding is attached are connected via an elastic body, and the top binding attachment portion and the heel binding attachment portion each have bending rigidity. A ski plate, comprising a layer and an elastic layer laminated on the lower surface of the rigid layer,

Is provided.

[0010]

[Operation] The vibration of the ski to which the plate is attached can be obtained by the action of the rigid layer and the elastic layer.

The strain generated between the top binding mounting portion and the heel binding mounting portion during ski running is absorbed by the elastic body.

Reference numeral 11 denotes a ski. In FIG. 1, the left side of the ski 11 is a ski top, and the right side is a ski tail. 1
2 is a ski plate. Ski plate 1
2 is a top binding mounting portion 21 to which the top binding 13 is mounted, and a heel binding 1
Heel binding mounting part 22 to which the four are mounted
Consists of

As shown in FIG. 3, each of the top binding mounting portion 21 and the heel binding mounting portion 22 has a rigid layer 31 and an elastic layer 3 from the front side.
2. The adhesive layer 33 is sequentially laminated from above. The rigid layer 31 is made of an aluminum plate having a thickness of 1 mm or less in this embodiment. The elastic layer 32 is made of a synthetic rubber or a natural rubber outside the SBR. The adhesive layer 33 is made of an adhesive such as a double-sided adhesive tape. That is, it has a certain degree of tackiness even when dried. The rigid layer 31 may be made of a metal plate other than the aluminum plate and a rigid plate other than the aluminum plate as long as the rigid layer 31 has relative rigidity as compared with the elastic layer 32. do it.

Reference numeral 23 denotes an elastic body. The elastic body 23 is made of a material having elasticity such as synthetic rubber, and connects the top binding mounting portion 21 and the heel binding mounting portion 22. The elastic body 23 penetrates from the front surface to the back surface, and the rigid layer 31 and the elastic body layer 3 of the top binding attachment portion 21 and the heel binding attachment portion 22
2. The thickness of the adhesive layer 33 is combined. Elastic body 23
Has a width of 2 mm or more as shown in FIG.

The mounting ends of the top binding mounting portion 21 and the heel binding mounting portion 22 with the elastic body 23 have irregularities in plan view, and the other convex portions 25 are provided corresponding to the one concave portion 24, respectively. And an elastic body 23 is connected between them. The unevenness may have a curved shape as shown in FIGS. 2, 7, and 9, or may be angular as shown in FIGS. Further, FIGS. 2 and 5
As shown in FIG. 6, one unevenness may be provided, or a plurality of unevennesses may be provided as shown in FIGS. Further, large and small irregularities may be combined as shown in FIG. Top binding attachment part 21 and heel binding attachment part 22
Since the mounting ends are mutually uneven, the two mounting portions are connected in an intricate state, and the length of the elastic body 23 is also long. Then, the bending between the top binding attachment portion 21 and the heel binding attachment portion 22 is absorbed. That is, the stress is dispersed by the unevenness.

The top binding attaching portion 21 is attached to a sock portion of the friction reducing plate 15 for opening the boot top of the top binding 13. Reference numeral 16 denotes a screw, which fixes the top binding 13 and the top binding attaching portion 21, and the heel binding 14 and the heel binding attaching portion 22, respectively.

Next, the operation of the embodiment will be described. By the action of the rigid layer 31 and the elastic layer 32, a vibration damping effect of the ski 11 to which the plate is attached can be obtained.

A top binding mounting portion 21 and a heel binding mounting portion 22 generated during skiing are provided.
Is absorbed by the elastic body 23.

[0020]

EFFECTS OF THE INVENTION A top binding mounting portion which is obtained during skiing while obtaining a ski damping effect,
Reduces the strain created between the heel binding attachment.
