Description

この発明は、雪の上を歩行する際に、足が積雪中に沈んでしまわないよう履き物に組み合わせて使用するものとして古くから使用されてきていて、その用途に供するものとして現在でも変わらず使用され続けている「かんじき」に代表される雪面歩行補助具に関するものであり、主に履物や運動娯楽用品に係わる技術分野に関係する外、金属材料、プラスチック材、竹材や木材等各種素材関係の技術分野、あるいはそれら素材を使って加工する技術分野等、凡そ人間生活に係わる全ての技術分野に属している。     This invention has been used for a long time as it is used in combination with footwear so that the foot does not sink in the snow when walking on snow, and it is still used as it is for its use It is related to snow surface walking aids represented by “Kanjiki”, which is continuously being used, mainly related to technical fields related to footwear and sports equipment, and various materials related to metal materials, plastic materials, bamboo materials, wood, etc. It belongs to all the technical fields related to human life, such as the technical field of the above, or the technical field of processing using these materials.

(視 点)
地球温暖化によって降る雪の量は、雪国北陸・東北・北海道地方でも相当減ってしまっているとはいうものの、雪が無くなってしまった訳ではなく、山間僻地や雪国地域で幹線道路から離れた除雪の行われない所等では、やはりそれなりの積雪はあり、活動するには雨天等に着用する履き物等で全く用をなさないため、今もって昔ながらの「かんじき」を着用するのが唯一有効な手段として継承されている状況にあり、雪国における冬期間の屋外活動において大いに活躍を続けている。
(point of view)
Although the amount of snow falling due to global warming has decreased considerably in the Snow Country Hokuriku, Tohoku, and Hokkaido regions, it does not mean that the snow has disappeared, but snow removal away from the main road in mountainous areas and snowy areas. In places where there is no such thing, there is still a certain amount of snow, and since there is no use for activities such as footwear worn in rainy weather etc., it is the only effective way to wear old-fashioned `` Kanjiki '' As a result, it continues to play an active role in outdoor activities during the winter in snowy countries.

周知のとおり、この「かんじき」は、「泥水や氷、雪等の軟弱な場面を歩行するときに使用する特殊な履物の総称」であって、「田下駄」、「鉄かんじき」「輪かんじき」の三種類に大別され、新石器時代に北欧から北アジア、北アメリカに伝播したものといわれ、我が国にも、縄文時代には既に使用されていたのではないかと考えられ、その後、様々な変遷を経てきた末に、構造としては、「1本の輪材で造られた円形・楕円形・瓢箪形をした単輪型」といわれるもの、「2本の輪材で造られた楕円形の複輪型」といわれるもの、そして「木または割竹を横に並べて簾のようにした簾編型」といわれるもの、の大きく分けて三つのタイプがあり、何れも雪に接する部分を歩行に支障を来さない範囲で、できるだけ拡大したものとすることによって雪に掛かる体重を分散、減少するようにし、長靴等の履き物が積雪中にぬがって歩行できなくしてしまうことを防止するよう、靴底を載せて余りある十分な大きさの楕円または輪形、瓢箪形とした輪郭部で体重を分散させると共に、使用者が着用時にバランスを保てるよう配慮して、略中心部分に靴底を載置、仮固定できるようにした靴載せ装着部を配し、先の輪郭部に渡し掛け、支持する構造のものとなってる。     As is well known, "Kanjiki" is a general term for special footwear used when walking in soft scenes such as muddy water, ice, and snow. It was said that it was spread from Northern Europe to North Asia and North America during the Neolithic period, and it was thought that it was already used by the Jomon period in Japan. After many years of transition, the structure is said to be "single-wheel type with a circle, ellipse, or saddle shape made from a single ring", and "an ellipse made from two rings." There are three main types, the so-called “double-wheeled shape” and the “knob-shaped type with wood or split bamboo arranged side by side,” all of which are in contact with snow. In the range that does not interfere with walking The size of the ellipse is large enough to put on the sole so that the weight on the snow is dispersed and reduced, and the footwear such as boots gets wet during the snow and prevents it from walking. Alternatively, a shoe mounting part that allows the user to balance the weight when wearing it with a ring-shaped or bowl-shaped contour, and to allow the user to maintain a balance when wearing it, so that the shoe sole can be placed and temporarily fixed at the approximate center part. It has a structure in which it is arranged, passed over the previous contour, and supported.

(従来の技術)
このように、「かんじき」としての機能上からは、体重を分散させる上で必要且つ十分な大きさを兼ね備えなていなければなず、しかも、上記のとおり、均衡を図って体重を分散させる必要性から、靴底はそれら輪郭部の中央辺りに位置させた構造、換言すれば、靴底の周囲に略均等に大きく広がった接雪面を有する構造になってしまうことから、普段の歩行をしようとすると、その左右の靴底の周囲に大きく広がった輪郭部を踏み合う格好になって前に進めないため、踏み合わないよう両足を開き、足を外側から夫々半円を描くようにした特殊な歩行(したがって、最初にある程度習熟する必要がある。)とならざるを得ないことと、無理な歩行の所為もあってその間の靴(主に防寒用長靴)との馴染みが悪くて外れてしまうか、外れないまでも歩行を疎外することとなって、長い時間の使用には耐えられず、確かに靴が雪中に沈み込んでしまうことは阻止できても、そのために要する特殊な歩行姿勢と靴との馴染みの悪さとによって体力を相当消耗させてしまうという難点が避けられず、そのため、何とか従来からの「かんじき」の歩行性の悪さを改善しようとする試みが過去に幾つも見受けられる。
(Conventional technology)
Thus, in terms of the function as “Kanjiki”, it must have the necessary and sufficient size to disperse the weight, and as described above, it is necessary to balance and disperse the weight. Because of this, the shoe sole has a structure that is located around the center of these contours, in other words, a structure that has a snow-contacting surface that spreads almost uniformly around the shoe sole. When trying to do so, it would look like it would step on the contours that greatly spread around the left and right shoe soles, so it could not go forward, so both feet were opened so that they would not step on, and each foot was drawn from the outside in a semicircle It is necessary to become a special gait (hence, it is necessary to become familiar with some degree first), and because of the reason of the unreasonable gait, the familiarity with the shoes (mainly winter boots) during that time is bad and it comes off. Or will not come off However, it will be alienated from walking, and it can not withstand use for a long time, and although it can certainly prevent the shoes from sinking into the snow, the special walking posture required for that and familiarity with the shoes Inevitably, the difficulty of exhausting the physical strength due to the poorness of the unavoidable is unavoidable, and there have been several attempts in the past to somehow improve the poor walking ability of the traditional “Kanjiki”.

例えば、昭和31年実用新案公告第3338号公報「輪かんじき」考案を始めとし、昭和44年実用新案公告第10379号公報に掲載のある「かんじき」考案や昭和64年実用新案公開第22385号公報の「かんじき」考案、あるいは、登録実用新案第3007225号公報にある「カンジキ」考案等々と、件数自体は些程多くはないにしろ、長年に渡って繰り返し同じ課題に取り組んできていたという経緯があることを確認できるものの、上記列挙したものを含め、これまでに提案のあったもの全てが、依然として歩行し難いという難点について十分対応できるところまでには至っておらず、したがって、実施化されて定着しているというものを見出せないのが実情である。     For example, the idea of “Kanjiki” published in utility model public notice No. 3338 published in 1964, the idea of “Kanjiki” published in utility model publication No. 10379 published in 1944, and utility model publication No. 22385 published in 1964 The idea of “Kanjiki”, or “Kanjiki” in Registered Utility Model No. 3007225, etc., has been working on the same issues over many years, although the number itself is not so small. Although it can be confirmed, all of the proposals so far, including those listed above, have not yet reached the point where they can still fully cope with the difficulty of walking. The fact is that we cannot find what we are doing.

(問題意識)
この発明は、以上のような状況に鑑み、その機能上からは、普段の歩行姿勢に比較して、ある程度の不自然さは残しても、何とか靴との馴染みをより良くして容易く外れてしまったり、不自然な歩行を助長してしまうことのないようにした着用性の良い「かんじき」の類いの雪面歩行補助具を案出できないものかと、雪国に住まいをする者の一人として古くから従来品の試験、分析をしてきた。
(Awareness of problems)
In view of the situation as described above, the present invention can be easily removed from the function by improving the familiarity with the shoes, even if a certain amount of unnaturalness remains, compared to the normal walking posture. As one of those who live in a snowy country, whether it is possible to devise a snow surface walking aid of the kind of “Kanjiki” that is easy to wear, so that it does not encourage walking or unnatural walking We have been testing and analyzing conventional products for a long time.

(発明の目的)
そこで、本願出願人は、その過程で得た知見に基づき、歩行の際の足への装着一体感に秀れていて、円滑な歩行が成し得るようにする改良された構造の雪面歩行補助具を創出することを狙いとし、逸速くその開発、研究に着手して長期に渡る試行錯誤と幾多の試作、実験とを繰り返してきた結果、今回、遂に新規な構造の雪面歩行補助具を実現化することに成功したものであり、以下では、図面に示すこの発明を代表する実施例と共に、その構成を詳述していくことにする。
(Object of invention)
Therefore, the applicant of the present application is based on the knowledge obtained in the process, and is excellent in the sense of unity on the foot during walking, and has an improved structure that enables smooth walking. With the aim of creating assistive devices, the development and research of it has been started quickly, and after many years of trial and error and numerous trials and experiments, we finally have a new structure on the snow surface. In the following, the configuration will be described in detail together with an embodiment representative of the present invention shown in the drawings.

(発明の構成)
この発明による雪面歩行補助具は、基本的に次のとおりの構成から成り立つものである。 即ち、長靴底面の輪郭を遥かに超える大きさの輪郭を有する雪面捕獲枠の前後方向略中央辺りか、やや前方寄りとなる個所を、主として靴底土踏まず辺りに当接する所定巾の渡し掛け部に形成する一方、該渡し掛け部には、それより前方の雪面捕獲枠に囲まれた空間内に延び、土踏まずよりも前側の靴底部分に当接するようにした甲部固定ベルト支持部を、またそれよりも後方の雪面捕獲枠に囲まれた空間内に延び、土踏まず辺りから踵までの靴底輪郭に略合致するものとし、その末端側の縁を靴踵外側面に沿って適宜高さ範囲に渡って立ち上がるようにした足首固定ベルト支持部を、夫々連続する一体状のもので、上下方向に適度に弾性変形可能に形成してなる構成を要旨とする雪面歩行補助具である。
(Structure of the invention)
The snow walking aid according to the present invention basically has the following configuration. In other words, a crossing portion of a predetermined width that mainly contacts the shoe sole arch around the center of the snow surface capture frame having a size much larger than the contour of the bottom of the boots in the front-rear direction approximately in the middle or slightly forward. On the other hand, the crossing portion is provided with an upper fixing belt support portion that extends into a space surrounded by a snow surface capturing frame ahead of it and is in contact with the shoe sole portion on the front side of the arch. In addition, it extends into the space surrounded by the snow surface capture frame behind it, and it should substantially match the shoe sole contour from the arch to the heel, with the edge on the end side as appropriate along the outer surface of the heel A snow surface walking aid that has a structure in which the ankle fixing belt support portion that stands up over a range of height is formed in a continuous and integral manner so that it can be elastically deformed appropriately in the vertical direction. is there.

この基本的な構成を、より具体的な構成のものとして示すと、長靴底面の輪郭を遥かに超える大きさの輪郭を有し、その輪郭に沿った内側所定幅部分が雪面捕獲枠に形成されると共に、該雪面捕獲枠の前後方向略中央辺りか、やや前方寄りとなる個所に、同雪面捕獲枠に囲まれた空間を横断し、靴底方向とは直交状配置とするようにした渡し掛け部を形成する一方、該渡し掛け部には、それより前方の雪面捕獲枠に囲まれた空間内に延び、土踏まずよりも前側の靴底部分に当接するようにした甲部固定ベルト支持部を、またそれよりも後方の雪面捕獲枠に囲まれた空間内に延び、土踏まず辺りから踵までの靴底輪郭に略合致するものとし、その末端側の縁を靴踵外側面に沿って適宜高さ範囲に渡って立ち上がるようにした足首固定ベルト支持部を、夫々連続する一体状のもので、上下方向に適度に弾性変形可能に形成してなるものとした構成の雪面歩行補助具となる。     When this basic configuration is shown as a more specific configuration, it has a contour that is far larger than the contour of the bottom of the boots, and an inner predetermined width portion along the contour is formed on the snow surface capturing frame. At the same time, approximately in the front / rear direction of the snow surface capture frame, or slightly forward, the space surrounded by the snow surface capture frame is crossed and orthogonal to the shoe sole direction. On the other hand, the upper part that extends into the space surrounded by the snow surface capturing frame in front of it and comes into contact with the shoe sole part on the front side of the arch The fixed belt support shall extend into the space surrounded by the snow surface capture frame behind it, and shall approximately match the shoe sole contour from the arch to the heel, with the edge on the end side outside the shoe heel Ankle fixation belt support that stands up over a range of heights along the side And each one integral-shaped continuous, the vertical direction moderately elastically deformable formed to become as that the structure of the snow surface walking aid.

さら具体的には、長靴底面の輪郭を遥かに超える大きさの輪郭を有し、その輪郭に沿った内側所定幅部分が雪面捕獲枠に形成されると共に、該雪面捕獲枠の前後方向略中央辺りか、やや前方寄りとなる個所に、同雪面捕獲枠に囲まれた空間を横断し、靴底方向とは直交状配置とするようにした渡し掛け部を形成する一方、該渡し掛け部には、それより前方の雪面捕獲枠に囲まれた空間内に延び、土踏まずよりも前側の靴底部分に当接するようにした甲部固定ベルト支持部を、またそれよりも後方の雪面捕獲枠に囲まれた空間内に延び、土踏まず辺りから踵までの靴底輪郭に略合致するものとし、その末端側の縁を靴踵外側面に沿って適宜高さ範囲に渡って立ち上がるようにした足首固定ベルト支持部を、夫々連続する一体状のもので、上下方向に適度に弾性変形可能に形成すると共に、少なくとも渡し掛け部および足首固定ベルト支持部の下面からは所定長さの食込み突部、またはピン付き食込み突部が下方に向けて突設されてなる構成の雪面歩行補助具が含まれる。     More specifically, it has a contour that far exceeds the contour of the bottom surface of the boots, and an inner predetermined width portion along the contour is formed on the snow surface capturing frame, and the front and rear direction of the snow surface capturing frame. Around the center or a little closer to the front, a crossing section that crosses the space surrounded by the snow surface capture frame and is arranged orthogonal to the shoe sole direction is formed. The hanging part has an upper fixing belt support that extends into a space surrounded by a snow surface capturing frame in front of it and is in contact with the shoe sole part on the front side of the arch. It extends into the space surrounded by the snow surface capture frame, and almost matches the shoe sole contour from the arch to the heel, and rises up to the appropriate height range along the outer edge of the shoe heel. The ankle fixing belt support portion thus made is a continuous one-piece, upper and lower And a biting protrusion with a predetermined length or a pinning protrusion with a pin projecting downward from at least the lower surface of the crossing part and the ankle fixing belt support part. Includes snow walking aids.

この発明の雪面歩行補助具は、使用者がバランスを取るときに爪先や踵に加わる力による反力は固よりのこと、もっとも大事な歩行前進に際しての爪先や踵の上下動によって加えられる力に起因して得られる筈の反力(キック力の一部)が、雪面捕獲枠の前後方向略中央辺りか、やや前方寄りとなる個所で土踏まず辺りに対応するよう規制した渡し掛け部に夫々一体形成した、爪先側の部分に対応する甲部固定ベルト支持部、および踵側の部分に対応する足首固定ベルト支持部の弾性変形による復元力として、夫々が確実に渡し掛け部から雪面捕獲枠に伝えられ、雪面捕獲枠から雪へと効率的に分散、支持されるようにしたことから、使用者が装着して足を踏み出したときに得られる歩行前進のためのキック力が効率的且つ安定したものとなって、柔雪のような降雪直後で深い雪面であっても所望どおりの行動を効果的に実施可能にするという、雪面歩行補助具として、従前までのかんじき等では到底達成することができなかった秀れた特徴を発揮できるものとなる。     The snow walking aid of the present invention has a strong reaction force due to the force applied to the toes and heels when the user balances, and the force applied by the vertical movement of the toes and heels during the most important walking advance The trap reaction force (a part of the kick force) obtained due to the snow is restricted to correspond to the arch around the center of the snow surface capture frame in the front-rear direction or slightly forward. As a restoring force due to elastic deformation of the upper part fixing belt support part corresponding to the toe side part and the ankle fixing belt support part corresponding to the heel side part, which are integrally formed, respectively, the snow surface is surely Since it is transmitted to the capture frame and efficiently dispersed and supported from the snow surface capture frame to the snow, the kicking force for walking advance obtained when the user wears and steps out Efficient and stable As a snow surface walking aid that makes it possible to effectively perform the desired action even on a deep snow surface immediately after snowfall, such as soft snow, it can be achieved at all by conventional wiping. It will be able to demonstrate the outstanding features that did not exist.

そして、この発明の雪面歩行補助具における雪面捕獲枠の前方側を斜め上方に傾斜させると同時に、後方側が、後方から見て下弦の月状に上方に湾曲させてあるもの、あるいは何れか一方を採用してなるもの等は、大股の動作の中にもその着地前後における雪面捕獲枠前端側および/または同後端側を雪面に引っ掛けて突っ込んでしまう割合が改善されることから、上記特徴に加え、歩行前進の動作、つまり交互に足を出していく動作が、そのような構成を採用していないものに比較して遥かに円滑なものにすることができるという大きな特徴も合わせもったものになる。     And, the front side of the snow surface capture frame in the snow surface walking aid of the present invention is inclined obliquely upward, and at the same time, the rear side is curved upward in the shape of a lower chord as viewed from the rear, or either In the case of using one of them, the ratio of the front and / or rear end of the snow surface catching frame hooked on the snow surface before and after the landing is improved even during the movement of the crotch. Therefore, in addition to the above features, the forward movement of walking, that is, the action of taking out the foot alternately, can be made much smoother than those that do not employ such a configuration. Will also be combined.

雪面捕獲枠は、使用する者が、後述する渡し掛け部に片足ずつ載せて全体重をこの発明の雪面歩行補助具に掛けたときに、雪面を捕らえてその荷重をできるだけ平均化して分散し、積雪中に深く沈んでしまわないようにする機能を果たすものであり、その機能を果たすため、最大で片足に全体重が加わえたとき(例えば、片足立ちのとき)であっても、その荷重を支持するに足るだけの面積の雪面を捕獲できているような大きさ(平面的な大きさだけに限定されず、立体的な形状を伴う大きさも含む。)、構造のものとして形成されなければならず、その大きさが確保されるものであれば、その全体輪郭形状は特に制限されず、後述の実施例に取り上げるような概略小判状形状のものから、従前までの伝統的なかんじきの形状である楕円形や円形、あるいは異形の瓢箪型の外、諸外国でオーソドックスな太短ソリ型等といった形状のものとすることが可能であり、上記したとおりの機能を達成可能とするだけの(したがって、長靴底面の輪郭を遥かに超える)大きさの輪郭を有するものとして形成される。     The snow surface capture frame, when the user puts one foot on the crossing section described later and hangs the entire weight on the snow surface walking aid of the present invention, captures the snow surface and averages the load as much as possible. It functions to disperse and prevent it from sinking deeply into the snow, and to fulfill that function, even when the maximum weight is added to one foot (for example, when standing on one foot) As a structure that can capture a snow surface with an area sufficient to support the load (not limited to a planar size, but also includes a size with a three-dimensional shape) As long as it has to be formed and its size is ensured, its overall contour shape is not particularly limited, and it has a generally oval shape as described in the following examples, and has traditionally been used. The shape of ellipse In addition to the shape or deformed bag shape, it can be of a shape such as an orthodox thick and short warp type in other countries, and can only achieve the functions described above (therefore, the bottom of the boots) It is formed as having a profile that is much larger than the profile.

それら所望の輪郭で予定された所定の大きさ、構造とする雪面捕獲枠は、夫々に全体重が掛かることを想定し、その全体重を雪面上に均衡させて分散させ得るだけの強度を有する素材、例えばポリエステルやポリエチレン、ポリカーボネート等といった比較的機械強度、耐久強度を兼ね備えたプラスチック材を単独でか、あるいはそれらを強化したFRP材や金属材と組み合わせた素材からなるもので、後述する構成要素各部と一体成形あるいはそれに近い連続、一体化したものとして形成するのが望ましいが、使い捨てタイプのものにする等といった特段の事情によっては、それら素材に拘泥することなく、その他の素材、例えば竹材や木質材等を単独でか、適宜組み合わせた上、接着剤や金物、紐等を使って連結、一体化してなるものとすることもできる。     The snow surface capture frame having a predetermined size and structure planned with the desired contour is assumed to have an overall weight, and the strength is sufficient to balance and distribute the entire weight on the snow surface. It is made of a material having a relatively high mechanical strength and durability such as polyester, polyethylene, polycarbonate, etc., or a material combined with an FRP material or a metal material reinforced with these materials, which will be described later. It is desirable to form each component as a single piece or as a continuous, integrated one, but depending on special circumstances such as making it disposable, other materials such as, for example, Bamboo, wood, etc. alone or combined as appropriate and then connected and integrated using adhesives, hardware, strings, etc. Rukoto can also.

そして、望ましくは、この雪面捕獲枠は、輪郭から内側に所定巾となって雪面を捕らえることとなる部分で、少なくとも平面形の左右両側に位置することとなる部分の主要部分が、その垂直断面で、後述の実施例にあるとおり、下に開口するV型断面のようなものとするか、あるいはV型断面を含む広く溝型のものとして形成されるようにすべきであり、それら全体側面形は殆ど直状のままに形成される外、少しでも歩行動作がし易くなるよう配慮して、全体側面形の中、平面形で前方側となる部分の主要部分だけが、側面形でやや斜め上方に傾斜した形状のものとするか、または渡し掛け部よりも前方辺りから全体が次第に斜め上方に傾斜していくようになるものにすると共に、平面形で後方側となる部分の主要部分が、後方から見て左右全幅か左右幅の大部分が下弦の月状に湾曲してなるようなものに形成すべきである。     Desirably, the snow surface capturing frame is a portion that captures the snow surface with a predetermined width inward from the contour, and at least a main portion of the portion that is positioned on both the left and right sides of the planar shape is The vertical cross section should be like a V-shaped cross section that opens downward, or as a wide groove type including a V-shaped cross section, as in the examples described later. In addition to the overall side shape being formed almost straight, only the main part of the front side of the flat side is the side shape. It should have a shape that is slightly inclined obliquely upward, or the entire portion gradually inclines obliquely upward from the front side of the crossing portion, and the rear portion of the planar shape The main part is left and right as seen from the rear Most of the width or horizontal width is to be formed like formed by curved waning moon shape.

渡し掛け部は、上記のようにして形成される雪面捕獲枠に渡し掛けられて、少なくとも全体重に相当する荷重を上記雪面捕獲枠に確実に伝えるようにする機能を果たすと共に、後述する甲部固定ベルト支持部および足首固定ベルト支持部を夫々形成、支持するための基部としての機能を果たし、使用者の長靴等冬履の靴底を安定して載置でき、しかも体重を伝える上で足裏への負担がなるべく苦にならない状態で伝えられる箇所にうまく当接するようにした機能をも果たすものであり、したがって、前記雪面捕獲枠の前後方向略中央辺りか、やや前方寄りとなる個所を、同雪面捕獲枠に囲まれた空間を横断して、靴底方向とは直交状配置とするようにした所定巾のもの、即ち、少なくとも全体重を受けてもその荷重を安全、確実に周辺の雪面捕獲枠に伝える上で十分な強度と配置構造とが考慮されたものでなければならない。     The passing portion is passed to the snow surface capturing frame formed as described above, and functions to ensure that a load corresponding to at least the total weight is transmitted to the snow surface capturing frame. It functions as a base for forming and supporting the instep fixation belt support and ankle fixation belt support so that it can stably place the sole of winter boots such as user's boots and convey weight. It also serves the function of making good contact with the point that is transmitted in a state where the burden on the sole is not as painful as possible. Of a predetermined width across the space surrounded by the snow surface capture frame and perpendicular to the shoe sole direction. Surely the surrounding snow surface A sufficient strength because they convey the caught frame and arranged structure shall have been considered.

上記目的、機能を実現するため、前記した雪面捕獲枠に対し、同一素材による一体成形、例えば圧延したものの打ち抜き成形や射出成形等、一体化成形手段として従前から採用されているあらゆる手段の採用が可能になる外、場合によっては、雪面捕獲枠とは別体のもの(したがって、必ずしも同一素材によるとは限らない。)として形成した上、両者間に予め設けてある強力な連結構造か、適宜介添え材を使う連結構造や介添え材を接着剤や溶着を使う連結手段等によって確りと連結、一体化してしまうようにするのが望ましいといえる。     In order to realize the above-mentioned purpose and function, any means that has been conventionally adopted as an integral molding means, such as integral molding of the same material, such as punching molding or injection molding of a rolled material, is adopted for the above-described snow surface capturing frame. In some cases, it is formed as a separate body from the snow surface capture frame (thus, not necessarily made of the same material), and a strong connection structure provided in advance between them. It can be said that it is desirable that the connecting structure using an intermediary material as appropriate or the intermediary material be securely connected and integrated by a connecting means using an adhesive or welding.

加えて、メーカーによって微妙に異なる靴底へ巧く当接してその状態を安定させるようにする上で都合の良い形状、構造のものであるべきであり、しかも、後述する甲部固定ベルト支持部や足首固定ベルト支持部の形成、支持を確実にするだけの強度も必要とし、しかも、使用中に甲部固定ベルト支持部や足首固定ベルト支持部に掛かる前進する際のキック力や制動反力、バランスを取るための支持力等を全て受支して確実に雪面捕獲枠に伝え得るだけのものとして形成するようにしなければならなず、そのための補強リブを付設するなり、刳り貫き孔を設ける、あるいはその大きさを選択する、材圧に変化を付ける等したり、断面形状を工夫して靴底に馴染む形とする、あるいは、靴底に当接する面にゴムやスポンジ体、厚手の生地その他緩衝、滑り止め等用に特殊素材を積層、一体化してなるものとする等、種々の工夫を取り入れることは自由であり、適宜必要に応じて採用可能になることは言うまでもない。     In addition, it should be of a shape and structure that is convenient for skillfully abutting slightly different shoe soles depending on the manufacturer to stabilize the condition, and the upper fixing belt support portion described later. In addition, it is necessary to have sufficient strength to ensure the formation and support of the ankle fixing belt support part, and the kicking force and braking reaction force when moving forward on the upper fixing belt support part and the ankle fixing belt support part during use It must be formed so as to be able to receive all the supporting force for balancing, etc., and transmit it to the snow surface capture frame reliably, and it will be provided with reinforcing ribs for that purpose. Select the size, change the material pressure, etc., devise a cross-sectional shape to fit the shoe sole, or rubber or sponge body, thick on the surface that contacts the shoe sole Other fabrics Collision, laminated special material for slip or the like, etc. and made integral, it is free to incorporate various measures, it is needless to say that allows employed depending on necessity.

甲部固定ベルト支持部は、上記渡し掛け部から、その前方の雪面捕獲枠に囲まれた空間内に、当該渡し掛け部に一体のものとしてか、別体としたものを適宜連結、一体化してなるものとして延伸、形成し、土踏まずよりも前側となる靴底部分、即ち爪先までの靴底全面をカバーできるものとしても差し支えないが、歩行性(つまり、歩行中に靴底との間に雪が挟まったり、雪面捕獲枠とは別に積雪面に食込み状となる状態等の不都合)を勘案して、後述する実施例のもののように親指の付け根辺りか、その近傍に当接するようにしたものとして形成され、長靴の甲部を着脱自在に固定する甲部固定ベルトを取着、支持する機能を果たし、後述する足首固定ベルトと相俟って、装着したこの発明の雪面歩行補助具が使用者の長靴から離脱してしまわないようにする機能が果たし得るようにすることを保証し得るものとしなければならない。     The upper part fixing belt support part is connected to the above hanging part in a space surrounded by the snow surface capturing frame in front of it, or it is connected to the hanging part as a single part or separately connected as appropriate. It can be stretched, formed, and covered with the sole part on the front side of the arch, that is, the entire shoe sole up to the toe. In consideration of inconveniences such as snow trapped on the snow surface and biting on the snow surface separately from the snow surface capture frame, etc., so that it touches the base of the thumb or the vicinity thereof as in the embodiments described later. Attaching and supporting the upper part fixing belt for detachably fixing the upper part of the boots, in combination with an ankle fixing belt, which will be described later. The tool has left the user ’s boots It must be assumed to be able to ensure that as the ability to be free I can play.

それと共に、使用者が装着し、足を踏み出して歩くときに、長靴の爪先側が雪面捕獲枠に囲まれた前方空間内で遊んでしまい、踏み出すための反力(キック力の一部)を得られなくしてしまわないようにする機能をも果たし、したがって、爪先側に掛けた力が、渡し掛け部を通じて雪面捕獲枠からの反力として効果的に得られるよう、それ自体の弾発力や渡し掛け部への連結強度が十分に勘案された上、最適な素材、形状、構造が予め吟味されることとなる。 なお、この甲部固定ベルト支持部におけるベルト取着部における固定ベルト脱着自在構造は制限されず、従前から公知の様々なベルト着脱、調節機構を事情に合わせて適宜選択、採用すれば足りる。     At the same time, when the user wears and walks while stepping on the foot, the toe side of the boots will play in the front space surrounded by the snow surface capture frame, and the reaction force to step out (part of kick force) It also functions to prevent it from being lost, so its own resilience so that the force applied on the toe side can be effectively obtained as a reaction force from the snow surface capture frame through the passing part In addition, the connection strength to the crossing portion is sufficiently taken into consideration, and the optimum material, shape, and structure are examined in advance. It should be noted that the fixing belt detachable structure in the belt attaching portion in the upper fixing belt support portion is not limited, and it is sufficient to appropriately select and adopt various known belt attaching / detaching and adjusting mechanisms according to circumstances.

一方、足首固定ベルト支持部は、前記渡し掛け部を挟んで上記した甲部固定ベルト支持部と反対側、即ち後方側に配設されるようになるものであり、渡し掛け部よりも後方の雪面捕獲枠に囲まれた空間内に延び、土踏まず辺りから踵までの靴底輪郭に略合致するものとして形成され、その末端側の縁を靴踵外側面には靴踵の輪郭に略沿うようにして適宜高さ範囲に渡って立ち上がって小壁部分を形成し、靴踵の後方移動を阻止し得るよう機能すると共に、同小壁部分を使って靴の足首部分を固定するためのベルトが着脱自在に装着できるようにする機能を果たすものである。     On the other hand, the ankle fixing belt support portion is disposed on the opposite side to the above-described upper fixing belt support portion with respect to the above-described hanging portion, that is, on the rear side. It extends into the space surrounded by the snow surface capture frame and is formed so as to substantially match the shoe sole contour from the arch to the heel, and the outer edge of the shoe heel is approximately along the contour of the shoe heel. In this way, a belt for standing up over an appropriate height range to form a small wall portion and preventing rearward movement of the shoe heel and fixing the ankle portion of the shoe using the small wall portion It fulfills the function of enabling detachable attachment.

更に当該足首固定ベルト支持部は、この発明の雪面歩行補助具を靴底に装着、使用しているときに、土踏まず部分から踵部分、特に踵の上下動に伴って得られる制動反力や姿勢バランス保持のための支持力等、歩行・停止作動に必要となる反力が確実に得られるようにする機能をも果たすものであり、それら反力が効果的且つ確実に雪面捕獲枠から渡し掛け部を介して伝えられるよう、それ自体の弾発力や渡し掛け部への連結強度が勘案され、最適な素材、形状、構造が吟味されることとなるのは、上記した甲部固定ベルト支持部の場合におけると同様であり、また、このベルト取着部への固定ベルト脱着自在構造はやはり制限されてはおらず、従前から公知の各種ベルト着脱、調節機構を事情に合わせて適宜選択、採用できることも、甲部固定ベルト支持部の場合のそれと全く同様である。     Further, the ankle fixing belt support portion is provided with a braking reaction force obtained from the arch portion to the heel portion, particularly when the heel is moved up and down, when the snow surface walking aid of the present invention is attached to the shoe sole. It also functions to ensure that the reaction force necessary for walking / stopping operation, such as support force for maintaining posture balance, is obtained, and these reaction forces are effectively and reliably removed from the snow surface capture frame. In order to be transmitted through the crossing part, the elastic material and the connection strength to the crossing part are taken into consideration, and the optimal material, shape, and structure are examined. This is the same as in the case of the belt support part, and the structure for detaching and fixing the fixed belt to the belt attachment part is not limited, and various conventionally known belt attachment / detachment and adjustment mechanisms are appropriately selected according to the circumstances. Can also be adopted, the upper It is exactly the same as that in the case of the constant belt support unit.

そして、少なくともこの足首固定ベルト支持部や渡し掛け部、必要があれば甲部固定ベルト支持部や雪面捕獲枠も加えた部分の下面からは、雪面からの滑り動作を阻止する機能を果たすための所定長さの食込み突部、またはピン付き食込み突部が下方に向けて突設されるようにししなければならず、それらの構造は特に限定されるものではなく、予め足首固定ベルト支持部や渡し掛け部等に一体的に形成してしまう定型のものとする外、それらとは別体の後付けのものとし、したがって、必要に応じて着脱使用ができたり、状況(柔らかい新雪面や、硬くざらついた堆積雪面等)に応じて構造の違うものを交換使用できたり、破損、紛失に際して補充することができるようなものとしても差し支えなく、例えばそれら個々の形状も、後述の実施例のように水平断面が矩形状のもので、それらの配置が矩形状の長辺方向を一部不揃いとなるようにしたものとする等、その機能達成のために必要かつ最適な配置具合と本数によるものとすることができる。 以下、上記したこの発明の雪面歩行補助具の構成が、より明確なものとなるように、その代表的な実施例について図面を参照しながら具体的な説明を加えていく。     And, at least from the lower surface of the ankle fixing belt support part and the crossing part, and if necessary, the upper part fixing belt support part and the snow surface capturing frame, the function of preventing the sliding operation from the snow surface is achieved. For this reason, it is necessary that the biting protrusion of a predetermined length or the pinning protrusion with a pin protrude downward, and the structure thereof is not particularly limited, and the ankle fixing belt support is previously provided. In addition to the fixed type that is integrally formed on the part and the hanging part, etc., it should be attached separately from them, so that it can be attached and detached as necessary, and the situation (soft fresh snow surface or Depending on the snow surface, etc., which is hard and rough, etc., it may be possible to replace and use different structures, or to be able to replenish in the event of damage or loss. As shown in the example, the horizontal cross section is rectangular, and the arrangement is such that the long side direction of the rectangular shape is partially irregular. It can depend on the number. In the following, a specific description will be given with reference to the drawings with respect to typical embodiments so that the configuration of the above-described snow walking aid of the present invention becomes clearer.

図1の片足に装着した状態を一点鎖線で加えたものの側面図、図2の同平面図、以下図3同底面図、図4同正面図、図5同背面図、図6同右側面図に示す各展開図、および図7のA〜A断面図、図8のB〜B断面図、図9のC〜C断面図、図10のD〜D断面図からも明確に把握できるように、この実施例に取り上げた雪面歩行補助具は、ポリカーボネートのような強度あるプラスチック製で、雪面捕獲枠と渡し掛け部とは勿論のこと、渡し掛け部とそれに連設、一体化される足首固定ベルト支持部および甲部固定ベルト支持部、そうして足首固定ベルト支持部および甲部固定ベルト支持部夫々に形成される各部分構成まで(但し、何れも足首固定ベルトないしは甲部固定ベルトは別体)が、一個取りの金型によって射出成形されてしまうようにした、この発明の基本的構成からなる代表的な事例によるものである。     1 is a side view of what is attached to one foot in a dotted line, a plan view of FIG. 2, a bottom view of FIG. 3, a front view of FIG. 4, a rear view of FIG. 5, a rear view of FIG. 7 and A-A cross-sectional view of FIG. 7, BB cross-sectional view of FIG. 8, CC cross-sectional view of FIG. 9, and DD cross-sectional view of FIG. In addition, the snow walking aid taken up in this embodiment is made of strong plastic such as polycarbonate and is integrated with and integrated with the crossing section as well as the snow surface capturing frame and the crossing section. Up to each partial configuration formed on the ankle fixing belt support part and the upper part fixing belt support part, and thus on each of the ankle fixing belt support part and the upper part fixing belt support part (however, either an ankle fixing belt or an upper part fixing belt) Will be injection molded with a single die To the is due Typical examples consisting of basic configuration of the present invention.

雪面捕獲枠1は、図のように全長が凡そ47ないし48cm前後、全幅が25ないし26cm前後の変形長円形、即ち両側縁の大部分を平行とし、その後方側を半径約12ないし13cmの半円形(したがって、側縁間の巾寸法が25センチ前後)の後端部12に形成するも、同前方側だけは、その半円形の頂部辺りを直線状に変形させてなる長円形の輪郭にすると共に、側面形は、その前方側の半円形頂部辺りを直線状に変形させた部分だけを斜め上方に傾斜させた構造のものとし、後方側の半円形部分は、後方から見て左右全幅か左右幅の大部分が下弦の月状に上方に湾曲してなるものに形成してある。     As shown in the figure, the snow surface capturing frame 1 is a deformed oval having an overall length of about 47 to 48 cm and an overall width of about 25 to 26 cm, that is, most of both side edges are parallel, and the rear side has a radius of about 12 to 13 cm. Although it is formed at the rear end 12 of a semicircular shape (therefore, the width between the side edges is about 25 cm), only the front side of the semicircular shape is formed by linearly deforming the top of the semicircular shape. In addition, the side shape has a structure in which only the part of the front side of the semicircular top that is linearly deformed is inclined obliquely upward, and the rear side semicircular part is left and right as viewed from the rear. The entire width or most of the left and right widths are formed so as to be curved upward in a moon shape of the lower chord.

そして、雪面捕獲枠1の直線状の前端部11側を除く大部分を、当該輪郭から平面巾4〜5センチ内外で高さが2〜3cm程度となる山形縦断面(上下転倒V字形縦断面)のものとし、前端部11側だけは、山形縦断面の外側となる片だけを上に開いて半ばソリ状形状にしてなる、厚さを1.5〜2mm程度のものとして形成してあり、山形縦断面に形成してなるその下面凹部に雪を抱え込むようにして雪面を捕獲、圧縮してしまうようにして、この発明の雪面捕獲枠1に加わる使用者の体重をうまく雪面に分散させてしまい、支持力の弱い雪面でも局所に荷重が集中しない状況を常時確保し続けられるようにすることにより、当該雪面捕獲枠1の雪面中への沈み込みが無くせるものとしてある。     And most of the snow surface capture frame 1 except for the straight front end portion 11 side is a mountain-shaped longitudinal section (vertical upside down V-shaped longitudinal section) having a height of about 2 to 3 cm inside and outside the plane width of 4 to 5 cm from the outline. Only the front end 11 side is formed with a thickness of about 1.5 to 2 mm, with only the outer part of the chevron vertical cross section opened upward to form a half warp shape. Yes, the snow surface is captured and compressed in such a way that the snow is held in the lower surface recess formed in the vertical cross section of the mountain, and the weight of the user who is added to the snow surface capturing frame 1 of the present invention is well controlled. It is possible to eliminate the sinking of the snow surface capturing frame 1 into the snow surface by always maintaining a situation in which the load is not concentrated locally even on the snow surface having a weak supporting force. As a thing.

この雪面捕獲枠1の前後方向略中央には、当該雪面捕獲枠1によって囲まれた空間を前後(つまり、使用時の踵から爪先)方向に概略二分するようにして、厚さが雪面捕獲枠1と略同等の1.5〜2mm程度の厚さで、表裏面側とも平板状とした渡し掛け部2を射出成形によって一体形成してあり、使用者の長靴等スノーシューズの種類に拘わらず、その土踏まず辺りにうまく馴染み、ずれてしまうことのないようにしてあり、さらに装着して歩行する際の足のキック力を確実に雪面捕獲枠1に伝え得るようにした強度を維持するために、図表示を省略しているが、リブも兼ねて全面に多数の凹凸部に形成(目的に適えば特にその凹凸形状は問わない。)してある。     In the approximate center of the snow surface capturing frame 1 in the front-rear direction, the space surrounded by the snow surface capturing frame 1 is roughly bisected in the front-rear direction (that is, from the heel to the toe in use). It has a thickness of about 1.5 to 2mm, which is almost the same as the surface capture frame 1, and has a flat hanging part 2 on both the front and back sides by injection molding. Regardless of the arch, the strength is such that it is well adapted to the arch and does not slip off, and that the foot kick force when wearing and walking can be reliably transmitted to the snow surface capture frame 1. In order to maintain the figure, the display of the figure is omitted. However, it is also formed with a large number of uneven portions on the entire surface also serving as ribs (the uneven shape is not particularly limited as long as it suits the purpose).

この渡し掛け部2からは、該渡し掛け部2と略同一面として前方側に3cm前後の巾で突き出し、三方を渡し掛け部2よりも前方側となる雪面捕獲枠1に囲まれたような状態にした甲部固定ベルト支持部3が一体、形成されると共に、同後方側には、当該渡し掛け部2に使用者のスノーシューズを所定どおりに載せるようにしたときの底載置部2よりも後ろに位置することとなる靴の踵部分までを載置可能とする形状、大きさを有し、やはり三方を後方側の雪面捕獲枠1に囲まれたような状態とした足首固定ベルト支持部4が一体、形成してある。     From this crossing part 2, it protrudes with the width of about 3 cm to the front side as the substantially same surface as this crossing part 2, and three sides seem to be surrounded by the snow surface capture frame 1 which becomes the front side rather than the crossing part 2. The instep fixed belt support portion 3 is integrally formed, and on the rear side, a bottom placement portion when the user's snow shoes are placed on the crossing portion 2 as prescribed. The ankle has a shape and size that can be placed up to the heel part of the shoe that will be located behind 2, and is also in a state surrounded by the snow surface capture frame 1 on the back side The fixed belt support portion 4 is integrally formed.

これら甲部固定ベルト支持部3および足首固定ベルト支持部4とも、上下方向に適度に弾性変形可能になるものに形成してあり、この発明の雪面歩行補助具を装着、使用する段に、渡し掛け部2に使用者の靴の土踏まず辺りを支持して体重を雪面捕獲枠1に分散、伝達するようにした状態から、歩行前進しようとしてそのための反力を得るために爪先側、踵側に交互に力を加えた場合に、従前までのものであれば、使用者の靴の爪先側の部分あるいは踵側の部分が自由、勝手に動いてその反力がうまく雪面捕獲枠1に伝わり難くなってしまうか、あるいは、周囲の雪面捕獲枠1に連結されていて動きが規制され、爪先側の部分あるいは踵側の部分の動きが雪面歩行補助具そのものの動きに直結してしまい、歩行前進に必要な動きがぎこちなくなってしまうかの何れかでしかなかったのに対して、それらの動きに追随支持し、適度な反発をもって上下する動作が極めて円滑なものとなるよう、その素材が予め吟味されるだけではなく、サイズを吟味した刳り貫き孔44,45を設ける等してあって、歩行前進の動作に都合が良くなる工夫がしてある。     These upper part fixing belt support part 3 and ankle fixing belt support part 4 are also formed so as to be appropriately elastically deformable in the vertical direction, and in the stage where the snow surface walking aid of this invention is mounted and used, In order to obtain a reaction force for trying to move forward from a state in which the arch of the user's shoes is supported by the crossing part 2 and the weight is dispersed and transmitted to the snow surface capture frame 1, If the force is applied alternately to the side, if it is a conventional one, the toe side portion or the heel side portion of the user's shoes are free, and the reaction force moves smoothly and the snow surface capturing frame 1 Or it is connected to the surrounding snow surface capture frame 1 and its movement is restricted, and the movement of the toe side part or the heel side part is directly linked to the movement of the snow surface walking aid itself. The movement necessary for walking forward is awkward The material was not only examined in advance so that the movement to move up and down with moderate repulsion would be extremely smooth, while following the movement. In addition, there are contrivances that make it convenient for advancing the walk, such as by providing drill holes 44 and 45 whose size has been examined.

なお、甲部固定ベルト支持部3は、靴巾を中央に取った両端辺りに、付属の甲部固定ベルト3aを組み込むためのベルト取着部31,31が設けてあり、また、足首固定ベルト支持部4の方には、後端縁を靴の踵の形状に略相当する円弧状のものに形成した上、その縁に沿わせて、図示にあるとおり、踵面の略全体が覆える程度の約5ないし8cm程度まで立ち上げた小壁42に形成してあって、装着時に当該足首固定ベルト支持部4から靴が勝手に外れてしまう靴の脱げ現象が起きないようにしてあり、そして、同小壁42にはベルト取着部41,41が穿孔されていて、該ベルト取着部41,41を使って付属の甲部固定ベルト4aを取り付け、使用段階には、その甲部固定ベルト4aを靴の足首部分前方側に廻すようにして固定できるようにしてある。     In addition, the upper part fixing belt support part 3 is provided with belt attaching parts 31 and 31 for incorporating the attached upper part fixing belt 3a around both ends of the shoelace in the center, and an ankle fixing belt. On the support portion 4, the rear end edge is formed in an arc shape substantially corresponding to the shape of the shoe heel, and the substantially entire surface of the heel is covered along the edge as shown in the figure. It is formed in a small wall 42 that is raised to about 5 to 8 cm, so that the shoe will not be detached from the ankle fixing belt support 4 when worn, The small wall 42 is perforated with belt attaching portions 41, 41, and the attached upper fixing belt 4a is attached using the belt attaching portions 41, 41. The fixing belt 4a can be fixed by turning to the front side of the ankle portion of the shoe. Unishi are.

また、これら甲部固定ベルト支持部3および足首固定ベルト支持部4は、使用者の長靴等スノーシューズの種類に拘わらず、その使用者の靴の爪先側の部分あるいは踵側の部分の靴底にうまく馴染み、ずれてしまうことのないようにすると共に、装着して歩行する際の足のキック力を確実に雪面捕獲枠1に伝え得るようにした強度を維持するため、渡し掛け部2の場合と同様に図表示を省略してしまっているが、リブも兼ねて全面に多数の凹凸部(目的に適えば特にその凹凸形状は問わない。)に形成してある。     The upper fixing belt support 3 and the ankle fixing belt support 4 are provided on the toe side portion or the heel side portion of the shoe of the user regardless of the type of snow shoes such as the user's boots. In order to prevent the slippage from getting out of place and to prevent the slippage, and to maintain the strength to ensure that the foot kick force when wearing and walking can be reliably transmitted to the snow surface capture frame 1, In the same way as in the case of FIG. 2, the illustration is omitted, but it is also formed with a large number of uneven portions (in particular, the uneven shape is not limited as long as it suits the purpose) also serving as a rib.

そして、渡し掛け部2の両側縁辺りの裏面、および足首固定ベルト支持部4の場合は、略靴のヒールに相当する辺りの裏面に、夫々下方方向に2〜3cm程度突出するようにしてなる食込み突部(場合によっては、先端に食込みを強化して滑り止め効果を高めるようにするピン付きの食込み突部としてもよい。)21,21、あるいは43,43,……を設けてあり、停止時は固より、歩行前進する場合にでも、雪面に踏み込んだこの発明の雪面歩行補助具の位置が不用意に滑って立ち姿勢を不安定にさせてしまうことのないようにしたものとしてある。それらの形成個数は限定されていないが、全方位における安定を求めるためにも、平面配置具合や一個一個の向き等に配慮したものとすべきであり、この実施例では、特に足首固定ベルト支持部4の食込み突部43,43,……の配置が、図からも判るとおり、平面矩形状の長辺方向が全て不揃いとなるようにして、全方位性が実現できるようにしてある。     And in the case of the back surface of the both sides of the crossing part 2, and the ankle fixing belt support part 4, it protrudes about 2 to 3 cm in the downward direction on the back surface of the area corresponding to the heel of the shoe. The biting protrusion (in some cases, it may be a biting protrusion with a pin that enhances the biting and enhances the anti-slip effect at the tip.) 21, 21, or 43, 43,... When stopping, even when walking forward, the position of the snow walking aid of this invention that has stepped on the snow surface will not slip carelessly and make the standing posture unstable. It is as. Although the number of them formed is not limited, in order to obtain stability in all directions, it should be considered in terms of the plane arrangement and the direction of each one. In this embodiment, in particular, the ankle fixing belt support As can be seen from the figure, the arrangement of the biting protrusions 43, 43,... Of the portion 4 is such that all the long sides of the plane rectangular shape are not aligned, so that omnidirectionality can be realized.

(実施例の作用)
この発明の雪面歩行補助具は、以上、詳述したとおりの構成からなるものであって、積雪地帯において、スノーシューズとして例えば長靴を履いている使用者は、先ず、当該雪面歩行補助具をできるだけ平坦な箇所に肩巾程度の間隔を空けて並べ置き、片足ずつ、夫々の土踏まず部分か、それよりもやや前方となる部分が渡し掛け部2に位置するように位置合せしながら、靴SのヒールS1が足首固定ベルト支持部4に設けられている円弧状の小壁42内側に当接状としてしまうことにより、自然に靴の爪先側の部分S3、正確には土踏まずS2に近い爪先側の部分S3が甲部固定ベルト支持部3上に位置するものとなって、その状態を維持しながら注意して、どちらからでも差し支えはないが、甲部固定ベルト支持部3、足首固定ベルト支持部4に組み込んである甲部固定ベルト3a、足首固定ベルト4aの何れも然るべき部位において着脱自在に固定するようにして、左右の長靴Sにこの発明の雪面歩行補助具を装着してしまう。この間の操作は、慣れてしまえば忽ち完了させることができる。
(Operation of Example)
The snow surface walking aid of the present invention is configured as described above in detail, and a user wearing, for example, boots as snow shoes in a snowy area, first, the snow surface walking aid Place the shoes on the flat part as much as possible with an interval of about the width of the shoulders, and align the shoes so that each foot is located on the crossing part 2 so that the part of each arch is slightly forward Since the heel S1 of the S is brought into contact with the inside of the arc-shaped small wall 42 provided on the ankle fixing belt support 4, the toe naturally close to the toe-side portion S3, more precisely, the arch S2 The side portion S3 is located on the upper fixed belt support portion 3, and while maintaining that state, there is no problem either way, but the upper fixed belt support portion 3, the ankle fixed belt Branch Instep ratchet belt 3a that is incorporated into part 4, as none of ankle brace belt 4a is detachably fixed at appropriate sites, thus wearing the snow surface walking aid of the invention to the left and right boots S. The operation during this time can be completed once you get used to it.

使用者は、装着したままの状態で、新雪が積ったままとなって未だ踏み固められていない雪面に向かって歩を踏み出せば、それまで装着するために止まっていた平坦で硬かった箇所では、裏面に突出している食込み突部32,32、あるいは43,43,……のために、うまく足裏を水平状にすることができずに不安定になっていたものが、それらは雪面の中に吸収されてしまって全く違和感なく普通の起立姿勢を保つことができることになる。但し、停止しているときでも、歩行を始めたときでも、この実施例の全長が凡そ47ないし48cm前後、全幅が25ないし26cm前後の変形長円形の雪面歩行補助具は、縦横寸法ともに2倍以上の大きさの履物となってしまうため、普段よりもかなり大股の姿勢を意識的にとるように心掛けないと、片方の雪面捕獲枠1でもう片方の雪面捕獲枠1を踏み付けて踏み付けてしまい、特に前進歩行体制に入っているとき等にこの状態に陥ってしまうと確実に前のめりに転倒してしまうことになり、慣れるまでの間は注意が必要となる。     If the user steps on the snow surface that is still worn and fresh snow is still piled up, the user must keep the flat and hard part that has been stopped for wearing. Then, because of the biting protrusions 32, 32 or 43, 43,... Protruding on the back surface, the soles could not be leveled well and became unstable. It is absorbed into the surface and can maintain a normal standing posture without any sense of incongruity. However, even when stopped or when walking is started, the deformed oval snow surface walking aid having a total length of about 47 to 48 cm and a total width of about 25 to 26 cm is 2 in both vertical and horizontal dimensions. Since it will be more than double the size of the footwear, you must step on the other snow surface capture frame 1 with one snow surface capture frame 1 unless you try to consciously take a large thigh posture than usual. If you fall into this state, especially when you are in a forward walking system, you will surely fall forward and you need to be careful until you get used to it.

異常な歩巾での歩行に慣れて難無く歩行前進が可能になると、この発明の雪面歩行補助具の場合は、一歩を踏み出そうとしてそのための反力を得るために爪先側、踵側に交互に力を加えたときに、従前までのものであったならば、使用者の靴Sの爪先側の部分S3あるいは踵側の部分S4が自由、勝手に動いてその反力がうまく雪面捕獲枠1に伝わり難くなっていたり、あるいは、周囲の雪面捕獲枠1に連結されていて爪先側の部分S3あるいは踵側の部分S4の動きが規制され、雪面歩行補助具そのものの動きに直結してしまい、歩行前進に必要な動きがぎこちなく、しかも足への負担が異常に掛かってしまっていて、何れにしても効率的な動作とするには程遠いものであったのに対し、爪先側の部分S3で踏み付けて得られる反力は甲部固定ベルト支持部3の弾性変形による復元力として、また踵側の部分S4で加えた力で得られる反力は足首固定ベルト支持部4の弾性変形による復元力として、夫々が渡し掛け部2から雪面捕獲枠1に伝わり、雪面捕獲枠1の大部分を占める縦断面山形断面の凹所に抱え込んだ雪に効率的に分散、支持される結果、柔雪の場合であっても決して雪面内に沈み込んでしまうこともなく、歩巾の広いことを除き、歩行前進の動きは極めて円滑なものとなってこの種器具として必要な作用を遺憾なく発揮できる。     If you are comfortable with walking with an unusual stride and you can walk forward without difficulty, in the case of the snow surface walking aid of this invention, in order to get a reaction force for trying to take one step, alternately on the toe side and heel side If the force is applied to the toe, the toe side portion S3 or the heel side portion S4 of the user's shoe S is free and moves freely, and the reaction force captures the snow surface well. It is difficult to be transmitted to the frame 1, or it is connected to the surrounding snow surface capture frame 1 and the movement of the toe side portion S3 or the heel side portion S4 is restricted, and directly connected to the movement of the snow surface walking aid itself However, the movement required for walking forward is awkward and the load on the foot is abnormal, and in any case it was far from efficient movement, but on the toe side The reaction force obtained by stepping on part S3 is the upper As the restoring force due to the elastic deformation of the constant belt support portion 3 and the reaction force obtained by the force applied at the heel side portion S4, as the restoring force due to the elastic deformation of the ankle fixing belt support portion 4, As a result of being efficiently dispersed and supported by the snow trapped in the recess of the mountain-shaped cross section that occupies most of the snow surface capture frame 1, it is never It does not sink in the plane, and the movement of walking forward is extremely smooth except for the wide stride, and the necessary action as this kind of device can be exhibited without regret.

(実施例の効果)
実施例に取り上げたこの発明を代表する構成による雪面歩行補助具の場合には、前述したこの発明の秀れた特徴を余すところなく実現可能にすると共に、雪面捕獲枠1の大部分を占める縦断面山形断面により、その凹所に雪面を確りと抱え込んで逃がすことがないものとなり、さらには甲部固定ベルト支持部3および足首固定ベルト支持部4各々の裏面に特定の位置関係で配してあるピン付き食込み突部32,32、あるいは43,43,……を設けて雪面に食い込み状になるようにしてあって、歩行を止めて停止したときは固より、歩行前進する最中でも、雪面に踏み込んだこの発明の雪面歩行補助具の位置が不用意に滑って立ち姿勢を不安定にしてしまうことがないという特筆すべき効果までももたらされることになる。
