この発明は、スキー板に関するもので、スキー
板の振動減衰性や、慣性モーメントや操縦性を改
良することにある。DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a ski, and its object is to improve the vibration damping properties, moment of inertia, and maneuverability of the ski.
（従来の技術）
従来より、スキー板には、木製、FRP製、メ
タルグラス製等のものが公知となつている。又最
近では、滑走中の振動をより早くすみやかに減衰
させて、スキー板の操縦性を改善するために種々
多様な素材を組み合わせたスキー板が提供されて
いる。(Prior Art) Conventionally, skis made of wood, FRP, metal glass, etc. have been known. Recently, skis have been provided that are made of a combination of various materials in order to more quickly attenuate vibrations during skiing and improve the maneuverability of the ski.
例えば、第１０図に示すスキー板１０のように
粘弾性材から成る振動減衰部材１１をスキー板の
用途と特性にあわせて、中芯長さ方向任意の位置
に任意数配設したものや、第１１図に示すように
スキー板のシヤベル部分１２に錘を包含させたプ
ラスチツク製の振動吸収装置１４を取り付けたス
キー板なども公知となつている。 For example, a ski 10 shown in FIG. 10 in which an arbitrary number of vibration damping members 11 made of a viscoelastic material are arranged at arbitrary positions along the length of the ski according to the purpose and characteristics of the ski; As shown in FIG. 11, skis are also known in which a plastic vibration absorbing device 14 containing a weight is attached to the shovel portion 12 of the ski.
これらスキー板においては、以下のような問題

あるため、テール部分（後端）１３で生じる振動

していた。 These skis had the following problems. That is, the ski 10 in FIG.
This structure can only be attached to the shovel part (tip) 12 of the ski, so it is not possible to reduce the vibrations generated at the tail part (rear end) 13. This had problems such as reduced maneuverability of the board.

来のスキー板の補強部材を配する位置に当るた
め、スキー板の強度や剛性に及ぼす影響が大き
く、スキー板自体の設計の自由度が著しく低下し
てしまうなどの欠点をも有していた。 In addition, the ski shown in FIG. 10 uses a flat plate vibration damping member 11 made of a viscoelastic material in which a restraining member such as piano wire or an aluminum plate is embedded in a rubber sheet or other viscoelastic material. However, even if a restraining member with a high elastic modulus is interposed, the vibration damping member itself does not have rigidity, so if you want to make the skis more rigid, you will need to use other reinforcing members. This has the disadvantage that the cost is relatively high, and the weight of the ski itself increases, resulting in poor maneuverability. Furthermore, since the vibration damping member 11 is a flat plate, it only damps vibrations in an average and distributed manner, and cannot quickly dampen desired areas, and the built-in position is similar to the position where a reinforcing member of a conventional ski is placed. This has the disadvantage that it has a large effect on the strength and rigidity of the ski, and the degree of freedom in designing the ski itself is significantly reduced.
そこで、こうした従来のスキー板の欠点を解消
するために、本発明者等は、特開昭59−166174号
に開示したようなスキー板、即ち第１２図に示す

発明した。 Therefore, in order to eliminate these drawbacks of conventional skis, the present inventors developed a ski as disclosed in JP-A-59-166174, that is, a ski with a protrusion on the upper surface as shown in FIG. 4, and the protrusion 4 is filled with a vibration absorbing material 4a, thereby inventing a ski that is easy to design in terms of rigidity, torsional strength, etc., has good vibration damping properties, and has excellent directivity. did.

などの問題点があつた。 However, the skis manufactured by the method disclosed in JP-A No. 59-166174 have improved the drawbacks of skis made before this published invention, but they do not have a roof or other protrusion in the center of the upper surface of the ski. Due to the shape of the skis, they can be scratched by crossing the skis or contacting the edges while skiing, and if used frequently, the marks and designs printed on the protruding parts of the top of the skis may be damaged. There were problems such as the images disappearing or becoming unrecognizable.

好ましい。(Means for Solving the Problems) To explain one embodiment of the present invention, as shown in FIGS. 1 and 2, an arbitrary portion (a first A core material 5 with excellent vibration damping properties, which is thicker on both sides of the ski width and thinner toward the center, is disposed between the core body 9 on the bottom surface (the figure shows the front and rear excluding the fastener mounting area). The ski board 1 is characterized in that a recess 2 that substantially matches the shape of the core material is formed in the upper surface component 6 at a portion corresponding to the core material. The shape of the recessed portion is preferably V-shaped in cross section as shown in the figure, as well as U-shaped, arcuate, or similar shapes.

作用を奏する。(Function) As described above, in the ski of the present invention, the width of both sides of the ski is thicker and the center part is thinner, between the upper surface component of the upper surface of the ski and the lower surface of the core. The core material has excellent vibration damping properties, so the vibrations of the skis that occur while skiing are reduced.
It is diffused in accordance with the thickness distribution of the core material, and the thicker side parts are quickly attenuated, so that the effect of making use of edges is achieved.

A core material 5 with excellent vibration damping properties, which is thicker on both sides of the width of the ski and thinner toward the center, is disposed between them, and the core material 5 is placed on the upper surface component of the area corresponding to the core material. This is a ski in which a concave portion 2 is formed which approximately matches the shape of the ski. The core material 5 is preferably made of foamed synthetic resin, lightweight wood, foamed light metal, synthetic resin containing microballoons, light rubber, or other materials singly or in combination. Then, as shown in Figures 8 and 9,
If a high elastic material 7 made of a metal plate such as aluminum, glass/carbon, boron, steel, or other fiber-reinforced plastic is built into the core material 5, the moment of inertia can be freely adjusted, and the bending rigidity and torsion are improved. Rigidity is also improved.

易になる。(Effects of the Invention) As described above, in the present invention, a center core with excellent vibration damping properties is formed between the upper surface component 6 and the core body 9, which is thicker on both sides of the width of the ski and thinner toward the center. Because the material 5 is provided, the vibrations that occur in the ski when skiing are damped more quickly on both sides than in the center of the width, making it easier to use the edge, and the recess formed in the upper surface component helps prevent twisting. Since the drag force is transferred to both side edges, the stiffness of both side edges of the ski is increased, and the edging operation during rotation becomes easier.
特に、上面構成部材に形成する凹部を締具取付
領域の前後の捩れやすい部分に設けると、この部
分の捩れに抗力を発揮し指向性が向上する。 In particular, if the recesses formed in the upper surface component are provided in areas that are prone to twisting before and after the fastener attachment area, resistance to twisting in these areas will be exerted and directivity will be improved.
