Description

【０００１】
【発明の属する技術分野】
本発明は積雪時に雪面を歩行する際に使用する雪面歩行具に関し、特に滑降による移動も可能な雪面歩行具に関する。
【０００２】
【従来の技術】
従来、積雪時に雪面を歩行する際に使用する器具としては、カンジキ、ワカン、スノーシュー等が知られている。これらの雪上歩行具は、靴底よりも広い接地面積を稼ぐことにより、積雪層内への沈み込みを抑制するとともに、スパイク状の突起（爪）をフレームの下面から突出させることで、滑り止めをしている。しかし、このような雪上歩行具では、積雪面の雪質に合わせた最適の接地面積を得ることができないうえ、斜面を登ることが難しいという問題があった。
【０００３】
そこで、歩行器具の骨枠を出退移動可能に組み合わされている前後パイプフレームで構成し、接地面積を調整可能したものが提案されている（例えば、特許文献１）。
【０００４】
【特許文献１】
特開２００１−１１２５１２号公報
【０００５】
【発明が解決しようとする課題】
ところが、前述の接地面積を調整可能にした雪上歩行具では、靴を固定している前フレームに対して、後フレームを出退するように構成しているから、歩行時には前端部分に荷重が集中し、後ろ側が長く延出する状態となることから、平地歩行時や下り坂歩行時には歩行し難いという問題がある上、靴固定部の下面にスパイク状突起が位置することから、下り坂時でも滑走することはできない。
【０００６】
本発明は、このような点に着目して、平地、上り坂、下り坂等、どのような地形状態にでも対応して安定した歩行ができるとともに、下り坂では滑降することも可能な雪上歩行具を提供することを目的とする。
【０００７】
【課題を解決するための手段】
上述の課題を解決するために請求項１に記載の発明は、下面をソール面に形成した短尺橇状の歩行具本体の前端寄り部分の下面に滑り止め突起を位置させ、歩行具本体の上面に靴固定具を前後移動可能な状態で配置し、この靴固定具を歩行具本体に少なくとも後端位置、中間位置、前端位置で選択的に固定可能に構成したことを特徴としている。
【０００８】
また、請求項２に記載の発明は、前記請求項１に記載した雪上歩行具での靴固定具を歩行具本体の後端位置に位置させた状態では、靴固定具の後部底部が歩行具本体の後端部分に係合して靴固定具の踵部が歩行具本体から浮かないように構成したことを特徴としている。
【０００９】
【発明の作用】
請求項１に記載した発明では、下面をソール面に形成した短尺橇状の歩行具本体の前端寄り部分の下面に滑り止め突起を位置させ、歩行具本体の上面に靴固定具を前後移動可能な状態で配置し、この靴固定具を歩行具本体に少なくとも後端位置、中間位置、前端位置で選択的に固定可能に構成していることから、靴固定具を歩行具本体の前端位置に固定した状態では、歩行具本体の前寄り部分に形成した滑り止め突起の上に靴固定具が位置することになる。このため、滑り止め突起に荷重（体重）が十分に作用することから、滑り止め突起が確りと雪面を捉えることになるうえ、後端部を雪面から離れた状態とすることで、歩行具本体と雪面との接触面積を低減させることができるから急な上り坂を移動する際に登りやすくなる。
【００１０】
また、靴固定具を歩行具本体の中間位置に固定した状態では、前後のバランスがとりやすく、歩行具本体の前寄り部分に形成した滑り止め突起にも適度な荷重が作用することになるから、軽いのぼり勾配や平地での歩行を楽に行うことができる。さらに、靴固定具を歩行具本体の後端位置に配置した状態では、後荷重となることから、歩行具本体の前端が雪面から浮くような状態となって歩行具本体の前寄り部分に形成した滑り止め突起への荷重が軽減されることにり、下り坂での滑降移動が可能となる。また、下り坂で歩行具本体の前端寄り部分を雪面から浮かすことによって、制動をかけた状態での滑降移動や、歩行下降が可能になる。
【００１１】
さらに、請求項２に記載したように、固定具を歩行具本体の後端位置に配置した状態で、後部底部が歩行具本体の後端部分に係合して靴固定具の踵部が歩行具本体から浮かないように構成した場合には、滑降移動時に靴と歩行具本体とが一体となることから、ショートスキーと同じ感覚で無理なく滑降することが出来ることになる。
【００１２】
【発明の実施の形態】
図は本発明の一実施形態を示す片側の雪上歩行具を示し、図１は一部を切除した分解斜視図、図２は縦断側面図、図３は平面図である。
この雪上歩行具は、短尺橇状の歩行具本体（１）と、この歩行具本体（１）の上面に前後移動可能な状態で配置した靴固定具（２）とからなり、歩行具本体（１）の前端寄り部分の底面に滑り止め突起（３）を位置させるとともに、滑り止め突起（３）の配設位置を除く部分をソール面（踏面）に構成してある。
【００１３】
歩行具本体（１）は、短尺金属製底板（４）の後端部と左右側部とに立上り壁（５）を形成するとともに、底板前端部分を斜め上方に反らせて短尺の橇状に形成し、底板（４）の前寄り部分に窓孔（６）を開設し、この窓孔（６）部分に側面視鋸歯状に形成した金属板（７）を配置し、この鋸歯先端部分を底板（４）の底面から下方に突出させることで滑り止め突起（３）としている。そして、立上り壁（５）の左右側壁部（５ａ）に後述する靴固定具（２）を歩行具本体（１）の後端位置、少なくとも１個所の中間位置、前端位置に固定するための係合孔（８）が透設してある。また、踵部に対応する立上り壁（５ｂ）では、底板（４）との間にスリット状の溝孔（９）が形成してある。
【００１４】
靴固定具（２）は、図示を省略した靴の踵部から中足部分までの側部に対応する立上り壁（１０）と、踏板（１１）と、この踏板（１１）の先端部分に配置した係合片（１２）とで構成してあり、係合片（１２）は中間巻回部を有する開きバネ（１３）の先端部をそれぞれ外側に折り曲げて形成した折り曲げ線材で構成してある。そして、係合片（１２）が前述の係合孔（８）に嵌まり込むことで靴固定具（２）を歩行具本体（１）に固定するようにしてある。また、踏板（１１）の後端部分（１４）は立ち上がり壁（１０）の後端位置よりも後まで突出しており、靴固定具（２）を歩行具本体（１）の後端位置にセットした状態では、この踏板（１１）の後端部分（１４）が歩行具本体（１）の立上り壁（５）での後端部分に形成したスリット状溝孔（９）に嵌まり込んで、靴固定具（２）の踵部が歩行具本体（１）から浮かないようにしている。
【００１５】
図中符号（１５）は、靴固定具（２）の立上り壁（１０）での踵部に対応する個所に形成した流れ止めバンド係合部、（１６）は靴固定具（２）の立上り壁（１０）の左右側壁中間部に形成した靴固定バンド係合部である。
【００１６】
上述の構成からなる雪上歩行具は、靴固定具（２）が歩行具本体（１）の中間位置や前端位置に位置している状態では、靴固定具（２）と歩行具本体（１）とは靴固定具（２）の先端部分に配置した係合片（１２）だけで連結されることになるから、その姿勢では靴固定具（２）の後端部すなわち靴の踵部分を歩行具本体（１）から浮かせることができる。この結果、靴固定具（２）を歩行具本体（１）の中間部分に配置した状態での平地や軽い登り勾配個所の歩行時、あるいは靴固定具（２）を歩行具本体（１）の前端部分に配置した状態での急勾配の登坂時に歩行具本体（１）を大きく持ち上げなくても良くなり、歩行を楽におこなえる。
【００１７】
また、靴固定具（２）を歩行具本体（１）の後端位置に位置させた状態では、靴固定具（２）の先端部分に配置した係合片（１２）での連結に加えて、靴固定具（２）の踏板後端部（１３）が歩行具本体（１）の踵部対応立上り壁（５ｂ）と底板（４）との間に形成したスリット状の溝孔（９）に挿入されて連結されることから、靴固定具（２）は靴の踵部を浮かせることなく、一体的に連結されることになるから、下り坂を降りる際にショートスキーとして滑降することが出来ることになる。この時、荷重（体重）は歩行具本体（１）の後端部に集中することになるから、歩行具本体（１）前端寄り部に配置した滑り止め突起（３）が滑降移動の邪魔になることは殆どない。また、下り坂を降りる際に歩行具本体（１）の前側を浮かすことにより、制動をかけた状態での滑降移動あるいは、踵部分を使用した歩行下降が行えることになる。
【００１８】
【発明の効果】
本発明では、下面をソール面に形成した短尺橇状の歩行具本体の前端寄り部分の下面に滑り止め突起を位置させ、歩行具本体の上面に靴固定具を前後移動可能な状態で配置し、この靴固定具を歩行具本体に少なくとも後端位置、中間位置、前端位置で選択的に固定可能に構成していることから、靴固定具を歩行具本体の前端位置に固定した状態では、歩行具本体の前寄り部分に形成した滑り止め突起の上に靴固定具が位置することになる。このため、滑り止め突起に荷重（体重）が十分に作用することから、滑り止め突起が確りと雪面を捉えることになるうえ、後端部を雪面から離れた状態とすることで、歩行具本体と雪面との接触面積を低減させることができるから、急な上り坂を移動する際に登りやすくすることができる。
【００１９】
また、靴固定具を歩行具本体の中間位置に固定した状態では、前後のバランスがとりやすく、歩行具本体の前寄り部分に形成した滑り止め突起にも適度な荷重が作用することになるから、軽いのぼり勾配や平地での歩行を楽に行うことができる。さらに、靴固定具を歩行具本体の後端位置に配置した状態では、後荷重となることから、歩行具本体の前端が雪面から浮くような状態となって歩行具本体の前寄り部分に形成した滑り止め突起への荷重が軽減されることになり、下り坂での滑降移動が可能となる。この時、歩行具本体の長さは短いが、培以上の安定感を感じることができる。また、下り坂で歩行具本体の前端寄り部分を雪面から浮かすことによって、制動をかけた状態での滑降移動や、歩行下降を可能にすることができる。
【００２０】
さらに、請求項２に記載したように、固定具を歩行具本体の後端位置に配置した状態で、後部底部が歩行具本体の後端部分に係合して靴固定具の踵部が歩行具本体から浮かないように構成した場合には、滑降移動時に靴と歩行具本体とが一体となることから、ショートスキーと同じ感覚で無理なく滑降することができる。
【００２１】
また、本発明に係る雪上歩行具は雪面のみならず、雪の少ないスキー場あるいは砂浜や砂丘でも雪上と同じように使用することができることから、サンドスキーとしてオールシーズンでしようすることが可能である。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a snow-walking device used when walking on a snow surface during snowfall, and more particularly to a snow-walking device that can be moved downhill.
[0002]
[Prior art]
Conventionally, swordfish, wakan, snowshoe, and the like are known as devices used when walking on the snow surface during snowfall. These snow-walking gears have a larger ground contact area than the soles of the snow to suppress sinking into the snow layer and prevent spike-like projections (claws) from projecting from the lower surface of the frame to prevent slipping. You are. However, with such a snow walking tool, there is a problem that an optimum contact area according to the snow quality of the snow-covered surface cannot be obtained, and it is difficult to climb a slope.
[0003]
In view of this, there has been proposed a structure in which a bone frame of a walking device is configured by front and rear pipe frames combined so as to be able to move in and out so that the contact area can be adjusted (for example, Patent Document 1).
[0004]
[Patent Document 1]
JP 2001-112512 A
[Problems to be solved by the invention]
However, in the above-mentioned snow-walking equipment with an adjustable contact area, the rear frame moves away from the front frame to which the shoes are fixed, so that the load concentrates on the front end when walking. However, since the rear side is extended for a long time, there is a problem that it is difficult to walk when walking on flat ground or when walking downhill.In addition, since the spike-shaped projection is located on the lower surface of the shoe fixing part, even when going downhill, You cannot glide.
[0006]
Focusing on such points, the present invention enables stable walking corresponding to any terrain condition such as flat ground, uphill, downhill, etc. The purpose is to provide tools.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the invention according to claim 1 is characterized in that a non-slip projection is located on a lower surface of a short sled-shaped walking tool body having a lower surface formed on a sole surface, near a front end, and an upper surface of the walking tool body is formed. The shoe fixing device is arranged so as to be able to move back and forth, and the shoe fixing device can be selectively fixed to the walking tool body at least at a rear end position, an intermediate position, and a front end position.
[0008]
According to a second aspect of the present invention, when the shoe fixing device of the snow walking device according to the first aspect is positioned at a rear end position of the walking device main body, the rear bottom portion of the shoe fixing device is a walking device. The shoe fixing device is characterized in that the heel portion of the shoe fixing device does not float from the walking device main body by engaging with the rear end portion of the main body.
[0009]
Effect of the Invention
According to the first aspect of the present invention, the anti-slip projection is positioned on the lower surface of the short sled-shaped walking tool main body having the lower surface formed on the sole surface, near the front end, and the shoe fixing tool can be moved back and forth on the upper surface of the walking tool main body. It is arranged in such a state that the shoe fixing device can be selectively fixed at least at the rear end position, the intermediate position, and the front end position to the walking device main body, so that the shoe fixing device is located at the front end position of the walking device main body. In the fixed state, the shoe fixing device is located on the anti-slip projection formed on the forward portion of the walking tool main body. For this reason, the load (weight) sufficiently acts on the anti-slip projection, so that the anti-slip projection captures the snow surface with certainty. Since the contact area between the tool body and the snow surface can be reduced, it is easy to climb when moving on a steep uphill.
[0010]
In addition, in a state where the shoe fixing device is fixed at the intermediate position of the walking tool main body, the front-rear balance is easy to take, and an appropriate load acts on the anti-slip projection formed on the front portion of the walking tool main body. This makes it easy to walk on light climbing slopes and on level ground. Furthermore, in the state where the shoe fixing device is arranged at the rear end position of the walking tool main body, since the rear load is applied, the front end of the walking tool main body floats from the snow surface, and the front portion of the walking tool main body is located near the front part. By reducing the load on the formed anti-slip projection, it is possible to slide downhill on a downhill. In addition, by lifting a portion of the walking tool body near the front end on a downhill from the snow surface, it is possible to perform a downhill movement or a walk down while braking is applied.
[0011]
Further, as described in claim 2, in a state where the fixing device is disposed at the rear end position of the walking device main body, the rear bottom portion engages with the rear end portion of the walking device main body, and the heel portion of the shoe fixing device walks. In a case where the shoe and the walking tool main body are integrated so as not to float from the tool main body during the downhill movement, the downhill can be smoothly downed with the same feeling as short skiing.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 shows a walking implement on one side showing one embodiment of the present invention, FIG. 1 is an exploded perspective view with a part cut away, FIG. 2 is a longitudinal side view, and FIG. 3 is a plan view.
This walking tool on snow consists of a short sled-shaped walking tool body (1) and a shoe fixing device (2) arranged on the upper surface of the walking tool body (1) so as to be movable back and forth. The non-slip projection (3) is located on the bottom surface of the portion near the front end of 1), and the portion other than the disposition of the anti-slip projection (3) is formed on the sole surface (tread surface).
[0013]
The walking tool body (1) forms a rising wall (5) at the rear end and the left and right sides of the short metal bottom plate (4), and forms a short sled by bending the front end of the bottom plate obliquely upward. Then, a window hole (6) is opened at a front portion of the bottom plate (4), and a metal plate (7) formed in a sawtooth shape in a side view is disposed at the window hole (6) portion. The non-slip projection (3) is formed by projecting downward from the bottom surface of (4). A shoe fixing device (2) to be described later is fixed to the left and right side wall portions (5a) of the rising wall (5) at the rear end position, at least one intermediate position, and the front end position of the walking implement body (1). A through hole (8) is provided. Further, a slit-shaped slot (9) is formed between the rising wall (5b) corresponding to the heel and the bottom plate (4).
[0014]
The shoe fixing device (2) is arranged at a rising wall (10) corresponding to a side portion from a heel portion to a middle foot portion of a shoe (not shown), a tread plate (11), and a tip portion of the tread plate (11). The engaging piece (12) is formed of a bent wire formed by bending the distal end of an open spring (13) having an intermediate winding portion outwardly. . Then, the shoe fixing device (2) is fixed to the walking tool body (1) by fitting the engaging piece (12) into the above-mentioned engaging hole (8). Further, the rear end portion (14) of the tread (11) projects beyond the rear end position of the rising wall (10), and the shoe fixing device (2) is set at the rear end position of the walking implement body (1). In this state, the rear end portion (14) of the tread plate (11) fits into the slit-shaped slot (9) formed in the rear end portion of the rising wall (5) of the walking tool body (1). The heel of the shoe fixing device (2) is prevented from floating from the walking device body (1).
[0015]
In the figure, reference numeral (15) denotes a flow stop band engaging portion formed at a position corresponding to a heel portion on a rising wall (10) of the shoe fixing device (2), and (16) denotes a rising portion of the shoe fixing device (2). It is a shoe fixing band engaging portion formed at the intermediate portion between the left and right side walls of the wall (10).
[0016]
The snow walking tool having the above-described configuration has the shoe fixing device (2) and the walking device body (1) when the shoe fixing device (2) is located at the middle position or the front end position of the walking device body (1). Is connected only by the engagement piece (12) arranged at the tip of the shoe fixing device (2), and in this position, the user walks the rear end of the shoe fixing device (2), that is, the heel portion of the shoe. It can be floated from the tool body (1). As a result, when the shoe fixing device (2) is placed in the middle part of the walking device main body (1), when walking on a level ground or a light uphill, or when the shoe fixing device (2) is placed on the walking device main body (1). The walking implement main body (1) does not need to be lifted greatly when climbing a steep slope with the front end portion disposed, so that walking can be performed easily.
[0017]
In the state where the shoe fixing device (2) is located at the rear end position of the walking tool body (1), in addition to the connection by the engaging pieces (12) arranged at the front end portion of the shoe fixing device (2), The rear end (13) of the tread plate of the shoe fixing device (2) has a slit-like slot (9) formed between the rising wall (5b) corresponding to the heel portion of the walking tool body (1) and the bottom plate (4). Since the shoe fixing device (2) is inserted and connected to the shoe, the shoe fixing device (2) is integrally connected without lifting the heel portion of the shoe, so that it is possible to slide down as a short ski when descending downhill. You can do it. At this time, since the load (weight) is concentrated on the rear end of the walking tool main body (1), the anti-slip projection (3) arranged near the front end of the walking tool main body (1) hinders the downhill movement. It rarely happens. In addition, by lifting the front side of the walking implement main body (1) when descending downhill, it is possible to perform downhill movement with braking applied or walking down using the heel portion.
[0018]
【The invention's effect】
In the present invention, the anti-slip projection is located on the lower surface near the front end of the short sled-shaped walking tool body having the lower surface formed on the sole surface, and the shoe fixing tool is arranged on the upper surface of the walking tool body so as to be movable back and forth. Since the shoe fixing device is configured to be selectively fixable to the walking tool main body at least at the rear end position, the intermediate position, and the front end position, in a state where the shoe fixing device is fixed to the front end position of the walking tool main body, The shoe fixing device is located on the anti-slip projection formed on the forward portion of the walking tool body. For this reason, the load (weight) sufficiently acts on the anti-slip projection, so that the anti-slip projection captures the snow surface with certainty. Since the contact area between the tool main body and the snow surface can be reduced, it is possible to easily climb when moving on a steep uphill.
[0019]
In addition, in a state where the shoe fixing device is fixed at the intermediate position of the walking tool main body, the front-rear balance is easy to take, and an appropriate load acts on the anti-slip projection formed on the front portion of the walking tool main body. This makes it easy to walk on light climbing slopes and on level ground. Furthermore, in the state where the shoe fixing device is arranged at the rear end position of the walking tool main body, since the rear load is applied, the front end of the walking tool main body floats from the snow surface, and the front portion of the walking tool main body is located near the front part. The load on the formed anti-slip projections is reduced, and it is possible to slide downhill. At this time, although the length of the walking tool body is short, it is possible to feel a sense of stability higher than the culture. In addition, it is possible to perform a downhill movement or a walking down with braking applied by floating a portion near the front end of the walking implement main body on a downhill from the snow surface.
[0020]
Further, as described in claim 2, in a state where the fixing device is disposed at the rear end position of the walking device main body, the rear bottom portion engages with the rear end portion of the walking device main body, and the heel portion of the shoe fixing device walks. In the case where the shoe and the walking tool main body are configured so as not to float from the tool main body at the time of downhill movement, it is possible to easily downhill with the same feeling as a short ski.
[0021]
In addition, since the snow walking implement according to the present invention can be used not only on the snow surface but also on a ski area with little snow or on a sandy beach or a dune in the same manner as on snow, it can be used as a sand ski in all seasons. is there.
