Description

本発明は、スノーボードやスキーなどの雪上滑走板に関し、特に、そのスプリット・テールに関する。 The present invention relates to snowboards such as snowboards and skis, and more particularly to a split tail thereof.

例えば、特開昭５６−１１６４７４に開示の如く、スキー板の尾端側中央にその尾端から切込みを長手方向に設けてこの切込みを挟んで互いに間隔を保つ一対の幅狭状の尾端片を形成したスプリット・テールを持つスキーが知られており、深雪（粉雪）滑走時においては幅狭状の尾端片が沈み込むことで相対的に先端湾曲部が浮き上がるため、滑走安定性を図ることができる。
特開昭５６−１１６４７４（図１、図２） For example, as disclosed in Japanese Patent Laid-Open No. Sho 56-116474, a pair of narrow tail pieces that are provided with a cut in the longitudinal direction from the tail end in the center on the tail end side of the ski, and keep the gap between the cuts. Skis with split tails are known, and when sliding on deep snow (powder snow), the narrow end of the tail sinks and the curved tip part rises relatively, so that the running stability is improved. be able to.
JP 56-116474 (FIGS. 1 and 2)

しかしながら、幅狭状の尾端片は撓み剛さと捩り強度が低くため、滑走時に暴れ易く、特に、固雪滑走時においては幅狭状の尾端片が過度に撓んだり、折損等が起り易い。 However, the narrow tail piece has low bending stiffness and low torsional strength, so it tends to run out during sliding, and in particular during narrow snow sliding, the narrow tail piece is excessively bent or broken. easy.

そこで上記問題点に鑑み、本発明の課題は、深雪（粉雪）滑走時においても固雪滑走時においても安定滑走が可能なスプリット・テールを備えた雪上滑走板を提供することにある。 Therefore, in view of the above-described problems, an object of the present invention is to provide a snowboard having a split tail that can be stably slid during both deep snow (powder snow) and solid snow.

上記課題を解決するために、本発明は、先端湾曲部を持つ長手状の滑走板本体の尾端側に切込みを当該尾端から長手方向に沿って設け、この切込みを挟んで互いに間隔を保つ一対の尾端片を形成した雪上滑走板において、滑走板本体の切込み近傍部に梁留め具で支持されており、切込みを覆う撓み変形可能な片持ち梁部材を有することを特徴とする。 In order to solve the above-mentioned problems, the present invention provides a cut along the longitudinal direction from the tail end of the longitudinal sliding plate body having a curved tip portion, and keeps a distance from each other across the cut. The snow slide board in which a pair of tail end pieces is formed is characterized in that it has a cantilever member that is supported by a beam fastener in the vicinity of the cut of the slide board body and that can be bent and deformed to cover the cut.

斯かる構成の雪上滑走板によれば、片持ち梁部材が一対の尾端片の反りを抑制する変形抑止機能を発揮するため、固雪滑走においては安定滑走を実現でき、折損事故を抑制できる。また、深雪（粉雪）滑走時においては片持ち梁部材が尾端片から浮き上がって適度に撓み変形し、切込みを介した雪の一部が片持ち梁部材と尾端片との隙間を上方へ通り抜けながら尾端片が沈み込んで先端湾曲側が浮き上がるので、安定滑走を実現できる。 According to the snow sliding board having such a configuration, the cantilever member exhibits a deformation suppressing function that suppresses the warping of the pair of tail end pieces, so that stable snow sliding can be realized and snow break accidents can be suppressed. . In addition, during deep snow (powder snow) sliding, the cantilever member floats from the tail end piece and deforms appropriately, and a part of the snow through the notch moves upward through the gap between the cantilever member and the tail end piece. The tail end piece sinks while passing through, and the curved side of the tip rises, so stable sliding can be realized.

片持ち梁部材を一対の尾端片の上面に対する法線方向に離接規制するガイド手段を設けることが望ましい。片持ち梁部材に幅方向の力が作用しても、ガイド手段が片持ち梁部材の幅方向へのブレを抑制できるため、片持ち梁部材及び梁留め具の故障を抑制でき、長寿命化に寄与する。 It is desirable to provide guide means for regulating the contact between the cantilever member and the upper surface of the pair of tail end pieces in the normal direction. Even if a force in the width direction acts on the cantilever member, the guide means can suppress the blurring of the cantilever member in the width direction, so that the failure of the cantilever member and the beam fastener can be suppressed and the life can be extended Contribute to.

このガイド手段としては、例えば、尾端片のそれぞれに設けたスリットと、片持ち梁部材の自由端側に固定されており、スリットに対応して遊嵌する差し込み片とを有する構成とすることができる。片持ち梁部材が撓んで尾端片から離れた際に、片持ち梁部材側の差し込み片が尾端片側のスリットになおも嵌って片持ち梁部材の横ブレや尾端片の過度な撓みを抑止できる。 As this guide means, for example, it is configured to have a slit provided in each of the tail end pieces and an insertion piece fixed to the free end side of the cantilever member and loosely fitted corresponding to the slit. Can do. When the cantilever member bends and moves away from the tail end piece, the insertion piece on the cantilever member side still fits into the slit on the tail end piece side, and the lateral deflection of the cantilever member or excessive bending of the tail end piece Can be suppressed.

また、梁留め具としては、片持ち梁部材の撓み剛性を増減可能な調節機構を有することが望ましい。適宜、片持ち梁部材の撓み剛性を調節できるため、深雪や固雪の雪質や深さの程度梁留め具としては、片持ち梁部材の固定端側に重ねる押え板と、この押え板において固定端寄りの第１の位置で片持ち梁部材を貫いて切込み近傍部に締着する１以上の第１の止めネジと、押え板において第１の位置よりも自由端寄りの第２の位置で片持ち梁部材を貫いて切込み近傍部に締着する１以上の第２の止めネジとを有し、この第２の止めネジに弾力性部材を嵌めて成ることが望ましい。第２の止めネジの締着加減による弾力性部材の締め付け力が変わり、片持ち梁部材の実質的な梁長さの可変により撓み剛性を変えることができる。 Moreover, as a beam fastener, it is desirable to have an adjustment mechanism which can increase / decrease the bending rigidity of a cantilever member. Since the flexural rigidity of the cantilever member can be adjusted as appropriate, the level of the snow quality and depth of deep snow and solid snow is limited to the press plate that is stacked on the fixed end side of the cantilever member and the press plate. One or more first set screws that pass through the cantilever member at the first position near the fixed end and fasten to the vicinity of the notch, and the second position closer to the free end than the first position in the presser plate It is desirable to have one or more second set screws that pass through the cantilever member and fasten in the vicinity of the incision, and a resilient member is fitted to the second set screws. The tightening force of the elastic member due to the tightening of the second set screw is changed, and the bending rigidity can be changed by changing the substantial beam length of the cantilever member.

FIG. 4 is a perspective view showing an enlarged exploded state of the tail side in the snow boat, and FIG. 5 is a cross-sectional view taken along the line AA ′ in FIG.

本例のスプリット・テール形スノーボードは、湾曲先端部１を持つ長手状のスノーボード本体１０の尾端側において、切込み３が尾端２から長手方向に沿って設けられており、この切込み３を挟んで互いに間隔を保ち二股に分かれた一対の尾端片５，６を有している。尾端片５，６の側縁はスノーボード本体１０の側縁を延長したものであり、尾端片５，６はスノーボード本体１０から後方へ張り出た略一様幅となっている。切込み３の奥縁は鈍角の略Ｖ字状となっている。また、図５に示す如く、切込み３に臨む尾端片５，６の内側面５ａ，６ａは下稜線よりも上稜線が切込み３に張り出た逆勾配面となっている。なお、図１〜図４においてはスノーボード本体１０に取り付ける靴留め具（ビンディング）が省略されている。 In the split-tail type snowboard of this example, a notch 3 is provided along the longitudinal direction from the tail end 2 on the tail end side of the longitudinal snowboard body 10 having the curved tip portion 1, and the notch 3 is sandwiched between the notches 3. And have a pair of tail end pieces 5 and 6 which are separated from each other and spaced apart from each other. The side edges of the tail end pieces 5 and 6 are obtained by extending the side edges of the snowboard body 10, and the tail end pieces 5 and 6 have a substantially uniform width projecting rearward from the snowboard body 10. The inner edge of the notch 3 has an obtuse angle V shape. Further, as shown in FIG. 5, the inner side surfaces 5 a, 6 a of the tail end pieces 5, 6 facing the notch 3 are reverse slope surfaces in which the upper ridge line projects from the notch 3 rather than the lower ridge line. In FIGS. 1 to 4, a shoe fastener (binding) attached to the snowboard body 10 is omitted.

このスノーボード本体１０においては、切込み近傍部７に梁留め具で支持されており、切込み３を覆う撓み変形可能な片持ち梁板８が設けられている。この片持ち梁板８は切込み３の全面を覆い、その両側が一対の尾端片５，６の上面に重なっている。片持ち梁板８の切込み近傍部７上に重なる固定端側は中央湾曲縁８ａとこれを間においた一対の前突片８ｂ，８ｃとを有している。 In this snowboard body 10, a cantilever plate 8 that is supported by a beam fastener and is supported by a beam fastener in the vicinity of the notch 7 and that covers the notch 3 can be deformed. The cantilever plate 8 covers the entire surface of the notch 3, and both sides thereof overlap the upper surfaces of the pair of tail end pieces 5 and 6. The fixed end side which overlaps with the notch vicinity part 7 of the cantilever plate 8 has a central curved edge 8a and a pair of front projecting pieces 8b and 8c sandwiching the central curved edge 8a.

片持ち梁板８を片持ち支持するための梁留め具としては、まず、片持ち梁板８の固定端側に重ねる押え板９を有する。この押え板９は片持ち梁板８の固定端側の形状に倣い、中央湾曲縁９ａとこれを間においた一対の前突片９ｂ，９ｃとを有する。また、この押え板９の前突片９ｂ，９ｃのネジ孔Ｈ_１で片持ち梁板８の前突片８ｂ，８ｃのネジ孔ｈ_１を貫いて切込み近傍部７に締着する２つの第１の止めネジＳ_１と、ネジ孔Ｈ_１よりも自由端寄りのネジ孔Ｈ_２で片持ち梁部材８のネジ孔ｈ_２を貫いて切込み近傍部７に締着する３つの第２の止めネジＳ_２とを有している。Ｗは金属製ワッシャであるが、第２の止めネジＳ_２には厚みのある弾力性ワッシャ（ゴムワッシャ）Ｘが嵌められている。なお、弾力性ワッシャＸの代りに、スプリングを用いても構わない。 As a beam fastener for supporting the cantilever plate 8 in a cantilever manner, first, there is a presser plate 9 that is superimposed on the fixed end side of the cantilever plate 8. The presser plate 9 has a central curved edge 9a and a pair of front projecting pieces 9b and 9c sandwiching the same, following the shape of the cantilever plate 8 on the fixed end side. The front protrusion 9b of the pressing plate 9, before protrusion 8b of the cantilever plate 8 by screw hole H ₁ of 9c, the two that fastened to the cut part near 7 through the screw hole h ₁ of 8c first One set screw S ₁ and a screw hole H ₂ closer to the free end than the screw hole H ₁ are passed through the screw hole h ₂ of the cantilever member 8 and are fastened to the incision vicinity portion 7. and a screw _{S 2.} W is a metal washer, the second the set screw S ₂ is fitted resilient washer (rubber washer) X a thick. In place of the elastic washer X, a spring may be used.

一方、尾端片５，６は板厚方向に貫く切込みスリット５ｂ，６ｂが形成されており、これに対応して、片持ち梁部材８の自由端側の隅部には、切込みスリット５ｂ，６ｂに遊嵌する差し込み片１１ａ，１２ａを持つＬ形金具１１，１２が設けられている。このＬ形金具１１，１２は片持ち梁部材８の自由端側の隅部に形成した取り付けスリット８ｄ，８ｅに差し込み片１１ａ，１２ａを挿入して接着固定されており、片持ち梁部材８を一対の尾端片５，６の上面に対する法線方向に離接規制するガイド手段として機能している。 On the other hand, the tail end pieces 5 and 6 are formed with slits 5b and 6b penetrating in the thickness direction. Correspondingly, the slits 5b and 6b are formed at the corners on the free end side of the cantilever member 8. L-shaped metal fittings 11 and 12 having insertion pieces 11a and 12a that are loosely fitted to 6b are provided. The L-shaped brackets 11 and 12 are bonded and fixed by inserting insertion pieces 11a and 12a into attachment slits 8d and 8e formed at the corners on the free end side of the cantilever member 8. It functions as a guide means for restricting contact / separation in the direction normal to the upper surfaces of the pair of tail end pieces 5 and 6.

このような構成のスノーボードにおいては、片持ち梁板８が一対の尾端片５，６の反りを抑制する変形抑止機能を発揮するため、固雪滑走においては尾端片５，６の過度な撓みを無くすことができ、安定滑走を実現できると共に折損事故を抑制できる。また、深雪（粉雪）滑走時においては片持ち梁板８が尾端片５，６から浮き上がって適度に撓み変形し、切込みを介した雪の一部が片持ち梁板８と尾端片５，６との隙間を上方へ通り抜けながら尾端片５，６が沈み込んで先端湾曲部１側が浮き上がるので、安定滑走を実現できる。 In the snowboard having such a configuration, the cantilever plate 8 exhibits a deformation suppressing function that suppresses the warping of the pair of tail end pieces 5 and 6. The bending can be eliminated, stable running can be realized and breakage accidents can be suppressed. In addition, during the deep snow (powder snow) run, the cantilever plate 8 floats up from the tail end pieces 5 and 6 and is appropriately bent and deformed, and a part of the snow through the incision is part of the cantilever plate 8 and the tail end piece 5. The tail end pieces 5 and 6 sink while passing through the gap with the upper end 6 and the tip bending portion 1 side rises, so that stable sliding can be realized.

この片持ち梁板８の撓み剛性は第２の止めネジＳ_２の螺着度合いで調節できる。即ち、第２の止めネジＳ_２を強くねじ込んで弾力性ワッシャＸを圧迫する程、片持ち梁板８の梁長さが実質的に短くなり、撓み剛性が大きくなるので、自由端側の撓み変形量を抑制でき、他方、第２の止めネジＳ_２を緩めて弾力性ワッシャＸの圧縮を緩和する程、片持ち梁板８の梁長さが実質的に長くなり、撓み剛性が小さくなるので、自由端側の撓み変形量を増大できる。このため、体重や雪質などに合わせて片持ち梁板８の撓み変形量を適宜調節でき、安定滑走を実現できる。 The flexural rigidity of the cantilever plate 8 can be adjusted in the second screwing degree of the set screw S _2. That is, as to compress the resilient washer X is screwed strongly second set screw S _2, since the beam length of the cantilever plate 8 becomes substantially shorter, flexural rigidity increases, deflection of the free end deformation amount can be suppressed, while the more relaxed compressive elasticity washer X by loosening the second set screw S _2, the beam length of the cantilever plate 8 becomes substantially longer, flexural rigidity is reduced Therefore, the amount of bending deformation on the free end side can be increased. For this reason, the amount of bending deformation of the cantilever plate 8 can be appropriately adjusted according to the weight, snow quality, etc., and stable sliding can be realized.

ここで、傾斜滑走やカーブ操作中では、片持ち梁板８が撓んだ際、片持ち梁板８と尾端片５，６のいずれか一方との間に大きな隙間を生じ、そこを通り抜ける雪の圧力で、片持ち梁板８に撓みや捩れ変形ばかりか、尾端片５，６に過度な撓みを伴うものとなり、片持ち梁板８又は梁留め具としての押え板９や止めネジＳ_１，Ｓ_２に緩みやガタツキなどの不具合の生じ、尾端片５，６の折損が生じる恐れがある。しかしながら、片持ち梁板８の捩れ変形に対しては弾力性ワッシャＸが緩衝材として作用し、また、ある程度の撓みや捩れに対して、差し込み片１１ａ，１２ａが切込みスリット５ｂ，６ｂに嵌っているため、片持ち梁板８の横ブレや尾端片５，６の過度な撓みを抑止できる。このため、片持ち梁板８，尾端片５，６や留め具の長寿命化を図ることができる。 Here, when the cantilever plate 8 is bent during slanting or curve operation, a large gap is generated between the cantilever plate 8 and one of the tail end pieces 5 and 6 and passes through the gap. Due to the pressure of snow, not only the cantilever plate 8 is bent or twisted, but also the tail end pieces 5 and 6 are excessively bent, and the cantilever plate 8 or the presser plate 9 as a beam fastener or a set screw. There is a possibility that defects such as looseness and rattling occur in S ₁ and S ₂ and breakage of the tail end pieces 5 and 6 may occur. However, the elastic washer X acts as a cushioning material against the torsional deformation of the cantilever plate 8, and the insertion pieces 11a and 12a fit into the slits 5b and 6b against a certain degree of bending and twisting. Therefore, it is possible to suppress lateral deflection of the cantilever plate 8 and excessive bending of the tail end pieces 5 and 6. For this reason, the lifetime of the cantilever plate 8, the tail end pieces 5 and 6, and the fastener can be increased.

なお、上記実施例は本発明を適用したスノーボードの例であるが、スキーなど一般に雪上滑走板において適用できることは云う迄もない。 In addition, although the said Example is an example of the snowboard to which this invention is applied, it cannot be overemphasized that it can apply in general on a snow slide board, such as skiing.
