Description

本発明は、氷雪域への登山に際して、登山靴の底に装着して使用する、靴底への雪ダンゴの付着防止するアンチスノー機能を備えたアイゼンに関する。 The present invention relates to a crampon provided with an anti-snow function for preventing snow dango from adhering to a shoe sole, which is used by being attached to the sole of a climbing shoe when climbing into an icy and snowy region.

アイゼンは、周知のように、一般に、雪山や氷壁などの地域への登山に際して、滑落等の事故を防止するために、登山靴の底に装着される。このアイゼンを装着して氷雪上を歩行すると、このアイゼンを装着した靴底に雪が付着して雪ダンゴに成長し、アイゼンの爪が機能しなくなって歩行が困難になり、さらに滑落などの事故を防止できなくなるおそれがあり、大変危険な状態になる。 As is well known, Eisen is generally attached to the bottom of climbing shoes in order to prevent accidents such as slipping when climbing to areas such as snowy mountains and ice walls. If you wear this crampon and walk on ice and snow, the snow will adhere to the sole of the cramp and will grow into a snow dango. The claws of the cramp will not work, making it difficult to walk and causing accidents such as sliding down. There is a risk that it will be impossible to prevent, and it will be very dangerous.

従来、このような靴底への雪ダンゴの生成を防止するために、例えば、特許文献１では、プラスチックシートやフィルムなどの離水性を有するシート類を、アイゼンの底面全体を覆うように装着し、このプラスチックシートやフィルムの縁をアイゼンフレームの周囲からその上面に折り返して貼着し、固定する雪ダンゴ付着防止シートが開示されている。また、特許文献２では、図５に示すように、ジョイント部材３３およびボルト４５、ナット４６により相互に連接されるフロントスパイク３１およびヒールスパイク３２の縁枠部３１ａ、３２ａに設けた複数の係合部３６、３８に、ゴムまたは合成樹脂等からなる、雪ダンゴ付着防止用のアンチスノープレート３４、３５にそれぞれ設けた複数の被係合部４０、４２を係合し、同様に突縁部４３、４４を縁枠部３１ａ、３２ａの受段部３７、３９に支持させることにより、アンチスノープレート３４、３５をフロントスパイク３１およびヒールスパイク３２に着脱自在に装着できるようにしたアイゼンが開示されている。
特開平７−８３０６号公報特開２０００−１３９５１５号公報 Conventionally, in order to prevent the generation of snow dango on such a shoe sole, for example, in Patent Document 1, a sheet having water repellency such as a plastic sheet or a film is attached so as to cover the entire bottom surface of the crampon. A snow dango adhesion preventing sheet is disclosed in which the edge of the plastic sheet or film is folded and adhered from the periphery of the crampon frame to the upper surface thereof and fixed. In Patent Document 2, as shown in FIG. 5, a plurality of engagements provided on the edge frame portions 31 a and 32 a of the front spike 31 and the heel spike 32 connected to each other by the joint member 33, the bolt 45, and the nut 46. A plurality of engaged portions 40, 42 provided on anti-snow plates 34, 35 made of rubber, synthetic resin, or the like, respectively, are provided on the portions 36, 38. , 44 is supported by the stepped portions 37, 39 of the edge frame portions 31a, 32a, so that the anti-snow plates 34, 35 can be detachably attached to the front spike 31 and the heel spike 32.

Japanese Patent Laid-Open No. 7-8306 JP 2000-139515 A

しかし、特許文献１および特許文献２に開示された、雪ダンゴ付着防止用のプラスチックシートやアンチスノープレートをアイゼンに装着しても、これらのシートやプレートに雪が全く付着しないわけではなく、付着した雪がダンゴ状に成長する前に、通常、登山者はピッケルで付着した雪を払い落とす。その際に、前記プラスチックシートやアンチスノープレートはピッケルにより損傷を受けやすく耐久性が低いため、前記シートやプレートは消耗品となり、損傷の程度に応じて、適宜、新品に装着しなおす必要があり、登山靴を履いたままの登山歩行過程で新品への装着が必要となる場合もある。特許文献１および２に開示されたように、前記シートやプレートのアイゼンへの装着が簡便化されたとはいえ、とくに登山歩行過程での新品への装着は、手間を要し、煩雑な作業となり、また、予備のシートやプレートを携行する必要があり面倒である。 However, even if the plastic sheet or anti-snow plate for preventing snow dango adhesion disclosed in Patent Document 1 and Patent Document 2 is attached to the crampons, snow does not adhere to these sheets or plates at all. Climbers usually wipe off snow attached to ice ax before the snow grows into a dango shape. At that time, since the plastic sheet and anti-snow plate are easily damaged by ice ax and have low durability, the sheet or plate becomes a consumable part, and it is necessary to reattach to a new article as appropriate according to the degree of damage. In some cases, it may be necessary to attach to a new product while climbing and walking while wearing mountaineering shoes. As disclosed in Patent Documents 1 and 2, although the mounting of the sheet or plate to the crampons has been simplified, mounting to a new article, especially during a mountain climbing process, is laborious and cumbersome. Also, it is troublesome to carry spare sheets and plates.

そこで、この発明の課題は、前記プラスチックシート類やアンチスノープレートを装着する必要がなく、登山中に煩雑な装着作業を伴わず、耐久性に優れた雪ダンゴ生成防止機能を有するアイゼンを提供することである。 Accordingly, an object of the present invention is to provide a crampon that does not require the mounting of the plastic sheet or anti-snow plate, and does not involve complicated mounting work during mountain climbing, and has an excellent durability for preventing snow dango generation.

A connecting member provided with a through hole, and one end side of the connecting member is locked to the front mounting frame portion, and the heel mounting frame portion and the connecting member are relatively slid to fit the shoe size, In the crampons in which an optimal through hole is selected from the plurality of through holes to connect and fix the front mounting frame portion and the heel mounting frame portion, the front mounting frame portion is connected to the toe side frame member. The frame member on the connecting member side is formed by gently connecting the both side surfaces of the frame member so that the front mounting frame portion is movable around the connected portion of the both side surfaces when walking. It is characterized by.

このように、つま先側の枠部材と連結部材側の枠部材とを緩やかに連結して、フロント装着枠部が歩行時に実質的に撓むようにすれば、雪が靴底に付着しても、歩行時にフロント装着枠部とともに靴底も撓むため、付着した雪がダンゴ状に成長する前に剥がれ落ち、雪ダンゴの成長を防止することができる。 In this way, if the frame member on the toe side and the frame member on the connecting member side are gently connected so that the front mounting frame part substantially bends during walking, even if snow adheres to the shoe sole, Since the shoe sole is bent together with the front mounting frame portion, the attached snow is peeled off before growing into a dango shape, and the growth of the snow dango can be prevented.

請求項３に係るアイゼンは、前記アイゼンを純チタンおよび／またはチタン合金で形成したことを特徴とする。 The crampons according to claim 3 are characterized in that the crampons are formed of pure titanium and / or a titanium alloy.

上記チタン金属で形成されたアイゼンは、従来の鋼製アイゼンに比べて重量が半減し、耐食性に優れ、またアルミ金属製アイゼンに比べて強度特性面で優れ、しかも外観面でも高級感があり、使用者に安心感も与える。 The crampons formed with the above titanium metal are half the weight compared to conventional steel crucibles, excellent in corrosion resistance, superior in strength characteristics compared to crucibles made of aluminum metal, and also have a high-class appearance. Gives the user a sense of security.

この発明では、アイゼンのフロント装着枠部の、つま先側の枠部材と連結部材側の枠部材とを、前記装着枠部を覆うように配置した可撓性を有する金属板で接続することにより、または、つま先側の枠部材と連結部材側の枠部材とをこの枠部材の両側で連結することにより、それぞれ形成するようにしたので、いずれのフロント装着枠部でも、歩行時に雪がフロント装着面の接地側面に付着しても、フロント装着面が撓むため、付着した雪がダンゴ状に成長する前に剥がれ落ち、雪ダンゴの成長を防止することができる。従って、本発明のアイゼンは、雪ダンゴ生成防止用のプラスチックシート類やアンチスノープレートを装着する必要がなく、登山歩行過程で煩雑な装着作業を伴わず、耐久性に優れた雪ダンゴ生成防止機能を有する。 In this invention, by connecting the toe side frame member and the connecting member side frame member of the front mounting frame portion of the crampon with a flexible metal plate arranged so as to cover the mounting frame portion, Alternatively, since the toe side frame member and the connecting member side frame member are connected to each other on both sides of the frame member, they are formed respectively. Even if it adheres to the ground contact side surface, the front mounting surface bends, so that the attached snow peels off before growing into a dango shape, and the growth of the snow dango can be prevented. Therefore, the crampons of the present invention do not require the installation of plastic sheets and anti-snow plates for preventing snow dango generation, and do not involve complicated mounting work during mountain climbing and walking, and have excellent durability for preventing snow dango generation.

この発明の実施形態は以上のような構成であり、以下にその作用について説明する。 The embodiment of the present invention is configured as described above, and the operation thereof will be described below.

前記フロント装着枠部２は、可撓性を有する金属板５で接続されてフロント装着面Ｆが形成されているため、アイゼン１を登山靴に装着して歩行するときに、フロント装着枠部２が撓んで、雪が靴底に接するフロント装着面Ｆの接地側面に付着しても、フロント装着面が歩行時に撓むため、付着した雪がダンゴ状に成長する前に剥がれ落ち、雪ダンゴの成長を防止することができる。また、上述のように、フロント装着枠部２が撓むことにより、従来のプラスチックシートやアンチスノープレートを装着する型式のアイゼンに比べて、歩行がしやすく、登山中の足の疲れも軽減される。さらに、図３（ａ）、（ｂ）に示したように、ヒール装着枠部３の直線状の枠部３ａに設けた突起１３を、連結部材４に設けた通し孔１４に嵌め込んで係合させる簡単な操作で、フロント装着枠部２とヒール装着枠部３との間隔を登山靴のサイズに適合するように連結・固定することができため、アイゼンの装着性が格段に向上する。 Since the front mounting frame portion 2 is connected by a flexible metal plate 5 to form a front mounting surface F, the front mounting frame portion 2 is used when walking with the crampons 1 mounted on mountain climbing shoes. Even if the snow bends and the snow adheres to the ground contact side of the front mounting surface F that contacts the shoe sole, the front mounting surface bends during walking, so the attached snow peels off before growing into a dango shape, and the snow dango grows. Can be prevented. In addition, as described above, the front mounting frame portion 2 is bent, so that it is easier to walk and the fatigue of the feet during climbing is reduced compared to the conventional type of crampons that are equipped with plastic sheets and anti-snow plates. The Further, as shown in FIGS. 3A and 3B, the protrusion 13 provided on the linear frame portion 3 a of the heel mounting frame portion 3 is fitted into the through hole 14 provided in the connecting member 4 to be engaged. Since the distance between the front mounting frame portion 2 and the heel mounting frame portion 3 can be connected and fixed so as to match the size of the mountaineering shoe by a simple operation to be combined, the wearing ability of crampons is remarkably improved.

図４は他の実施形態のアイゼンの要部を示したもので、図１および図２に示したアイゼンとは、フロント装着枠部２の構造のみが異なる。この実施形態では、つま先側の枠部材２ａと連結部材４側の枠部材２ｂの両側面の連結部位に、接地側への折り曲げ部１９、１９がそれぞれ形成されている。そして、それぞれの枠部材２ａ、２ｂを、その連結部位を連結したときにフロント装着枠部２が連結部位の周りに可動となるように、所要の間隔をおいて対向させ、両側の折り曲げ部１９、１９を、接続片２０、２０を介して、ボルト２１およびナット２２で緩やかに、すなわちルース(loose)に締結して、フロント装着枠部２が実質的に撓むように形成されている。このようしてフロント装着部２を形成すれば、連結部ががたついて実質的に撓むため、氷雪域での歩行の際に、このアイゼンを装着した靴底が、アイゼンを装着しないときと同様に撓んで、靴底に付着した雪がダンゴ状に成長する前に剥がれ落ち、雪ダンゴの成長を防止することができる。 FIG. 4 shows a main part of a crampon according to another embodiment. Only the structure of the front mounting frame 2 is different from the crampons shown in FIG. 1 and FIG. In this embodiment, bent portions 19 and 19 to the ground side are formed at the connecting portions on both side surfaces of the toe side frame member 2a and the connecting member 4 side frame member 2b, respectively. And each frame member 2a, 2b is made to oppose at a required space | interval so that the front mounting frame part 2 may move around a connection part when the connection part is connected, and the bending part 19 of both sides is carried out. , 19 are loosely fastened with bolts 21 and nuts 22 via connecting pieces 20, 20, that is, loosely, so that the front mounting frame 2 is substantially bent. If the front mounting portion 2 is formed in this manner, the connecting portion rattles and substantially bends. Therefore, when walking in an icy and snowy area, the shoe sole on which this crampon is worn does not wear the crampon. It can be bent in the same manner as above, and the snow attached to the shoe sole can be peeled off before growing into a dango shape, thereby preventing the snow dango from growing.

なお、前記チタン合金としては、Ｔｉ−６Ａｌ−４ｖなどのα−β合金、１５Ｖ−３Ｃｒ−３Ｓｎ−３Ａｌなどのβ型合金、α合金およびニアα合金のいずれの合金をも用いることが可能であり、いずれも、通常、焼鈍状態での使用で充分である。 As the titanium alloy, any one of α-β alloys such as Ti-6Al-4v, β-type alloys such as 15V-3Cr-3Sn-3Al, α alloys, and near α alloys can be used.
