Not only severe winter mountain climbing, but also snowy low mountains, summer snowy valleys, or slipping It is effective to prevent slipping even in easy muddy roads. And although there are a lot of light crampons used for such light climbing, it is difficult to put on and take off, it is inconvenient to carry, or depending on the type of shoes It was difficult to say that a satisfactory product was provided because it had either a problem that it was impossible to wear, or it was easily shifted back and forth or left and right while walking.

そこで本発明者はこれらの問題点を解決すべく新たな軽アイゼン（特許文献１）を提案した。
これは、「相互にフレキシブルなジョイント部材で結合され、各々に複数のスパイクを備えたフロントプレート及びヒールプレートと、これらを登山靴に装着するためのバンド手段とを備えたアイゼンに於いて、

かつ前記バンド手段を構成する後部抱持バンド、前上部抱持バンド、該後部抱持バンド及び該前上部抱持バンドの各延長結合片並びに各着脱延長片を弾性材で構成した軽アイゼン」である。 Therefore, the present inventor has proposed a new light crampon (Patent Document 1) to solve these problems.
This is "in the Aizen equipped with a front plate and a heel plate, which are coupled with each other by flexible joint members, each having a plurality of spikes, and band means for attaching them to a mountain climbing shoe.
The spike is a plurality of protrusions projecting downward from both the front plate and the heel plate, each of which includes a protrusion that integrally includes a lateral misalignment prevention pin that rises above the front plate and the heel plate. And
The band means;
A rear holding band supported by a rear rising chain raised from both sides of the heel plate, the rear holding band supporting the rear portion of the shoe in a holding state;
Of the two front riser chains raised from both sides of the front plate, it is connected to the two front riser chains on one side and detachably connected to the two front riser chains on the other side.

And the rear holding band, the front upper holding band, the rear holding band, the extension coupling pieces of the front upper holding band, and the attachment / detachment extension pieces of the front upper holding band constituting the band means " is there.

このような軽アイゼンは、先に述べたそれ以前のアイゼンと比べれば、その着脱も簡単であり、携帯にも不都合がなく、かつ登山靴の種類を問わずに装着可能であり、加えて歩行中に前後若しくは左右にずれたりするような問題もなく優れたものであるということができる。 Such light crampons are easier to put on and take off than the earlier crampons mentioned earlier, are not inconvenient to carry, and can be worn regardless of the type of climbing shoes, and in addition to walking It can be said that it is excellent without any problem of shifting back and forth or from side to side.

しかしその後の更なる検討により、雪が部分的に消えたガレ場、或いは木の枝等が錯綜した灌木帯その他のエリアをこれを外さずに歩いた場合に、バンド手段として使用する弾性材を、その構成上、板状ゴム材を打ち抜いたような部材で構成せざるを得ない関係上、それが損傷する虞を否定し得ないことが明らかになった。 However, by further examination after that, when walking without removing the gale field where the snow partially disappeared, or the shrub belt or other areas where the branches of trees were complicated, the elastic material used as a band means, In view of the configuration, it has been clarified that there is no denying the possibility of damaging it due to the fact that the rubber plate must be made of a member that has been punched out.

またこの軽アイゼンは、それ以前のアイゼンと比べれば、非常に装着の容易なものではあるが、その装着に際し、登山靴でそのヒールプレート及びフロントプレートを踏んだ状態で、結合用の複数のバンド部材を外側から内側に回してそれらの各先端のフックを内側の部材のリングに掛けるように操作すべきものであるため、各バンド部材の弾力により外側又は内側に引張られがちとなり、内外バランス良く装着するのがやや面倒で、使い勝手の点で若干改善の余地がない訳でもないことが分かった。 Also, this light crampon is much easier to wear than the previous crampons, but when it is worn, it can be attached to a plurality of bands that are used for joining with the heel plate and front plate stepped on with climbing shoes. The members should be operated from the outside to the inside so that the hooks at their tips are hooked on the ring of the inside member. It turned out to be a little cumbersome to do and there was no room for improvement in terms of usability.

そこで、本件出願人は、以上のような従来の軽アイゼンの問題点を解決し、靴の種類を問わずに簡単に、かつ左右のバランス良く装着でき、更に靴の踵側上部は堅くしっかりと係止可能であるとともに、靴の前甲部は必要以上に締付けないように配慮し、加えて安全な歩行を確保するため歩行中は靴に確実に固定されるものである一方で、使用部材の内、特に弾性材について損傷の危険性を低くした、携帯にも便利な軽アイゼンを提供することを目的として新たな軽アイゼンを提案した（特許文献２）。 Therefore, the Applicant has solved the problems of the conventional light crampons as described above, can be easily and well-balanced regardless of the type of shoes, and the upper side of the shoe is firmly and firmly attached. In addition to being able to be locked, the front part of the shoe should not be tightened more than necessary, and in addition, it is securely fixed to the shoe during walking to ensure safe walking. Among them, a new light cramp has been proposed for the purpose of providing a light cramp that is easy to carry and reduces the risk of damage particularly with respect to an elastic material (Patent Document 2).

The fastener 21 is a day-shaped member as viewed from the flat or bottom surface made of a plastic material, and the buckle member 11 is also shaped like an eye when viewed from the flat or bottom surface formed from a plastic material. It is a member. As shown in FIG. 1 and FIG. 2 (a), the main belt member 12 is inserted into the gap on the rear side of the central shaft portion 21a of the fastener 21 from below and passes above the central shaft portion 21a. Inserted into the front gap from above and extended downward, extended as it is, inserted into the gap between the rear shaft portion 11a and the front shaft portion 11b of the buckle member 11 from below, and folded back at the rear shaft portion. 11a passes through the gap on the rear side of the rear shaft portion 11a from above and advances downward, and then returns to the rear on the forward belt as it is. From above, and is inserted from above into the gap on the rear side through the central shaft portion 21a, and pulled strongly backward as it is and fixed at this position. By appropriately adjusting the folding length from the buckle member 11, the length from the intervening ring 7 of the main belt member 12 to the buckle member 11 can be appropriately adjusted.

前記主ベルト部材１２及び副ベルト部材９の後端の介在環７との結合は、図１及び図２(a)、(c)に示すように、各々の後端に結合した長方形の辺に沿った形状の結合環１２ａ、９ａを利用して行うこととしたものである。具体的には、該主ベルト部材１２及び該副ベルト部材９のいずれの場合も、これらと該介在片７、７とは、該介在環７の上辺を該結合環１２ａ、９ａを結合したベルト後端の直前に位置させた上で、該主ベルト部材１２及び該副ベルト部材９のベルト本体を該介在環７の上辺を巻くように折り返し、かつ該結合環１２ａ、９ａ中を貫通させて引き出すことにより結合したものである。 As shown in FIGS. 1 and 2 (a) and 2 (c), the main belt member 12 and the sub belt member 9 are joined to the rear end of the intermediate ring 7 on rectangular sides joined to the rear ends. This is performed by using the connecting rings 12a and 9a having the shape along the line. Specifically, in any case of the main belt member 12 and the sub belt member 9, these and the interposition pieces 7, 7 are belts in which the upper side of the interposition ring 7 is coupled to the coupling rings 12a, 9a. The belt main body of the main belt member 12 and the sub belt member 9 is folded back so as to wrap around the upper side of the intervening ring 7 after passing through the coupling rings 12a and 9a. Combined by pulling out.

前記主ベルト部材１２の先端のバックル部材１１と副ベルト部材９の先端側との着脱自在な結合は種々の態様で行うことが可能である。この実施例では、図２(b)に示すように、該副ベルト部材９の先端を該バックル部材１１の後軸部１１ａと前軸部１１ｂの間の隙間に下方から挿入し、上方で前方に折り返し、前軸部１１ｂの前方の隙間に上方から挿入し、該バックル部材１１の下方で先端方向に延長した上で該バックル部材１１の上方に折り返して、該上方を後方に延長し、後軸部１１ａの後方の隙間に上方から挿入し、該バックル部材１１の下方と主ベルト部材１２の間を後方に強く引く態様で結合を固定する。 The detachable coupling between the buckle member 11 at the tip of the main belt member 12 and the tip side of the sub belt member 9 can be performed in various ways. In this embodiment, as shown in FIG. 2 (b), the tip of the sub belt member 9 is inserted into the gap between the rear shaft portion 11a and the front shaft portion 11b of the buckle member 11 from below, And then inserted into the front gap of the front shaft portion 11b from above, extended in the front end direction below the buckle member 11, then folded back above the buckle member 11, and extended upward to the rear. The coupling is fixed in such a manner that the space between the lower part of the buckle member 11 and the main belt member 12 is pulled backward in the gap behind the shaft part 11a.

前記ベルト環２２は、前記連結片１３を主ベルト部材１２に取り付けるための手段であり、前記し、図１、図２(a)及び図４に示すように、主ベルト部材１２の途中に移動可能に緩やかに外装したものであるが、より詳細には、先端と留め具２１との間のベルトが二重になっている部位に外装したものである。該ベルト環２２は、主ベルト部材１２及び副ベルト部材９と同様な伸縮性のない強靱なベルト素材で環状に構成するものであり、このとき、前記前記連結片１３の取付スリット１３ｃに該ベルト素材を通過させた上で、その両端を結合し、該主ベルト部材１２と留め具２１及び介在環７との結合前に、該主ベルト部材１２に外装しておくものである。 The belt ring 22 is a means for attaching the connecting piece 13 to the main belt member 12, and moves in the middle of the main belt member 12 as shown in FIGS. 1, 2A and 4. Although it is gently packaged as much as possible, in more detail, it is packaged at a portion where the belt between the tip and the fastener 21 is doubled. The belt ring 22 is formed of a tough belt material having no stretchability similar to the main belt member 12 and the sub belt member 9, and at this time, the belt 13 is formed in the attachment slit 13c of the connecting piece 13. The material is allowed to pass through, and both ends thereof are coupled, and the main belt member 12 is sheathed before the main belt member 12 and the fastener 21 and the intervening ring 7 are coupled.

なお、前記連結片１３は、図１に示すように、平面又は底面から見て概ね四辺形を基本とする板状部材であり、その中央部に後方に向かって直線に伸び最奥部でＴ字状に両側方に伸びる導入スリット１３ｂを有し、該導入スリット１３ｂの最奥部の両側端部から各々前方に伸び、最前部で中央側に若干膨らんだ連結スリット１３ａ、１３ａを備え、更に最も奥側には奥側の片に沿った取付スリット１３ｃを備えたものである。なお該連結スリット１３ａ、１３ａ及び取付スリット１３ｃは、都合により一部を先に説明した。 As shown in FIG. 1, the connecting piece 13 is a plate-like member that is basically a quadrangle as viewed from the plane or bottom surface, and extends in a straight line toward the rear at the center, and is T at the innermost part. It has introduction slits 13b extending in the shape of both sides in the shape of characters, and includes connection slits 13a, 13a that extend forward from both ends of the innermost part of the introduction slit 13b and slightly swell toward the center at the frontmost part. The innermost side is provided with a mounting slit 13c along the inner side piece. The connecting slits 13a and 13a and the mounting slit 13c have been partially described above for convenience.

前記上部抱持ベルト１４は、前記主ベルト部材１２及び副ベルト部材９と同様の伸縮性のない強靱なベルト素材を用いて構成したものであり、先に述べ、図１、図３(a)、(b)及び図４に示すように、両端の掛止環１５、１５を介して前記フロントプレート１の両側の側部抱持鎖１６、１６間を接続するように配したベルト部材である。 The upper holding belt 14 is constructed by using a tough belt material having no stretchability similar to the main belt member 12 and the sub belt member 9, and as described above, FIG. 1 and FIG. 3 (a). 4 (b) and FIG. 4, the belt member is arranged so as to connect between the side holding chains 16 and 16 on both sides of the front plate 1 via the retaining rings 15 and 15 on both ends. .

該上部抱持ベルト１４は、特に図３(a)に示すように、その一端は、前記主ベルト部材１２及び副ベルト部材９の後端と前記介在環７、７との結合と同様に、該一端に結合した長方形の辺に沿った形状の結合環１４ａを利用して一方の掛止環１５に結合し、その他端は、二つのほぼ正方形の辺に沿った形状の四辺形の結合環１４ｂ、１４ｃ及び連結ベルト環１４ｄを利用して他方の掛止環１５に結合するようにしたものである。 As shown in FIG. 3 (a) in particular, the upper holding belt 14 has one end thereof similar to the connection between the rear ends of the main belt member 12 and the sub belt member 9 and the intervening rings 7 and 7, The coupling ring 14a having a shape along a rectangular side coupled to one end is coupled to one retaining ring 15, and the other end is a quadrilateral coupling ring having a shape along two substantially square sides. 14b, 14c and the connecting belt ring 14d are used to couple to the other retaining ring 15.

なお該掛止環１５は、図１、図３(c)、(d)及び図４に示すように、針金状部材で構成したほぼ二等辺三角形の辺に沿って三角形に構成した部材であり、該上部抱持ベルト１４の両端は、いずれもその底辺と結合することとしたものである。なおまた前記結合環１４ｂ、１４ｃは、後述するように、該上部抱持ベルト１４の長さ調節手段を兼ねるものでもある。 As shown in FIGS. 1, 3 (c), 3 (d) and 4, the hook ring 15 is a member configured in a triangle along the side of a substantially isosceles triangle formed of a wire-like member. Both ends of the upper holding belt 14 are connected to the bottom thereof. The coupling rings 14b and 14c also serve as length adjusting means for the upper holding belt 14 as will be described later.

まず該上部抱持ベルト１４の一端は、掛止環１５とは、図３(a)、(c)に示すように、その底辺を前記結合環１４ａを結合した該上部抱持ベルト１４の一端の直前に位置させた上で、そのベルト本体を、該掛止環１５の底辺を巻くように折り返し、かつその後該結合環１４ａ中を貫通させて引き出すことにより結合したものである。 First, as shown in FIGS. 3A and 3C, one end of the upper holding belt 14 is one end of the upper holding belt 14 having the bottom side coupled to the coupling ring 14a. The belt main body is folded so as to wind the bottom side of the retaining ring 15, and then coupled by pulling out through the coupling ring 14a.

該上部抱持ベルト１４の他端は、図３(a)、(b)、(d)に示すように、前記結合環１４ｂ、１４ｃの内部を通過させた上で折り返し、外部側の結合環１４ｃの一辺上を通過させた上で、再度内側の結合環１４ｂの内部を通過させて元の方向に戻すべく引き、該結合環１４ｂ、１４ｃの前記一辺と平行な他辺側を同時に強く引くことで該結合環１４ｂ、１４ｃと該上部抱持ベルト１４との結合を確実なものとする。また図３(a)、(b)、(d)に示すように、該当する側の掛止環１５は、その底辺に連結ベルト環１４ｄを外装状態に配し、同様に該結合環１４ｂ、１４ｃの前記一辺と平行な他辺側にも該連結ベルト環１４ｄを外装状態に配し、これによって該結合環１４ｂ、１４ｃと掛止環１５との相互の結合を確保する。要するに該結合環１４ｂ、１４ｃと掛止環１５とは、前者の該当する辺と後者の底辺とを前記連結ベルト環１４ｄの内部を通すことにより、相互に連結するものである。 As shown in FIGS. 3 (a), 3 (b), and 3 (d), the other end of the upper holding belt 14 is folded after passing through the inside of the coupling rings 14b and 14c. After passing through one side of 14c, it is pulled again to pass through the inside of the inner coupling ring 14b and return to the original direction, and the other side parallel to the one side of the coupling rings 14b, 14c is pulled strongly at the same time. As a result, the coupling between the coupling rings 14b and 14c and the upper holding belt 14 is ensured. Further, as shown in FIGS. 3A, 3B, and 3D, the retaining ring 15 on the corresponding side has a connecting belt ring 14d arranged on the bottom side in an exterior state, and similarly, the coupling ring 14b, The connecting belt ring 14d is also arranged on the other side parallel to the one side of 14c so as to ensure mutual coupling between the coupling rings 14b and 14c and the retaining ring 15. In short, the coupling rings 14b and 14c and the retaining ring 15 are connected to each other by passing the corresponding side of the former and the bottom of the latter through the inside of the connecting belt ring 14d.

更に該上部抱持ベルト１４には、図１、図３(a)及び図４に示すように、ベルト環１７を外装する。これは、該上部抱持ベルト１４の掛止環１５及び結合環１４ｂ、１４ｃとの結合の前に行うのが都合がよい。結合後であれば、後者の結合環１４ｂ、１４ｃとの結合を解除した上で行う。結合環１４ｂ、１４ｃとの結合の解除は、該上部抱持ベルト１４の上側のベルトを結合環１４ａ側から連結ベルト環１４ｄ側に押し戻して緩め、図３(b)に示すように、結合環１４ｂ、１４ｃの間隔を広げ、更に上側のベルトを戻しながら下側のベルトを結合環１４ａ側に引けば容易に行うことができる。こうした後に、前記ベルト環１７を該上部抱持ベルト１４に外装する。 Further, the upper holding belt 14 is provided with a belt ring 17 as shown in FIGS. This is conveniently performed prior to coupling of the upper holding belt 14 with the retaining ring 15 and the coupling rings 14b, 14c. If it is after the bonding, the bonding with the latter bonding rings 14b and 14c is released. To release the coupling with the coupling rings 14b and 14c, the upper holding belt 14 is loosened by pushing back the belt from the coupling ring 14a side to the coupling belt ring 14d side, as shown in FIG. 3 (b). It can be easily performed by widening the distance between 14b and 14c and pulling the lower belt toward the coupling ring 14a while returning the upper belt. After that, the belt ring 17 is mounted on the upper holding belt 14.

なお、序でに上部抱持ベルト１４の長さの調節の仕方を述べると、前記し、図３(b)に示すように、結合環１４ｂ、１４ｃの間隔を広げれば、必要に応じて、同図中上側のベルトを右側に移動させ、下側のベルトを左に移動させて、該上部抱持ベルト１４の長さを長くすることができるし、下側のベルトを右に移動させ、上側のベルトを左に移動させて、該上部抱持ベルト１４の長さを短くすることができる。結合環１４ｂ、１４ｃは、上部抱持ベルト１４の長さ調節手段としても機能するわけである。 In the introduction, how to adjust the length of the upper holding belt 14 will be described. As shown in FIG. 3 (b), if the interval between the coupling rings 14b and 14c is widened, if necessary, In the figure, the upper belt is moved to the right, the lower belt is moved to the left, the length of the upper holding belt 14 can be increased, the lower belt is moved to the right, The upper belt 14 can be shortened by moving the upper belt to the left. The coupling rings 14 b and 14 c also function as a length adjusting means for the upper holding belt 14.

該ベルト環１７は、前記上部抱持ベルト１４と同様に伸縮性のない強靱なベルト素材で構成した無端ベルト状部材であり、予め係止リング１８を係止した状態で構成する。図１、図３(a)及び図４に示すように、該係止リング１８は、これを該ベルト環１７に交差状態にして該ベルト環１７に係止するものである。なおこの係止リング１８は、針金状部材で円環状に形成してなるものである。 The belt ring 17 is an endless belt-like member made of a tough belt material that does not stretch as in the case of the upper holding belt 14, and is configured in a state where a locking ring 18 is locked in advance. As shown in FIGS. 1, 3 (a) and 4, the locking ring 18 is engaged with the belt ring 17 by crossing the locking ring 18 with the belt ring 17. The locking ring 18 is formed of a wire-like member in an annular shape.

また該係止リング１８には、前記し、かつ図１、図３(a)及び図４に示すように、両端に連結球１９、１９を結合した連結紐２０の中央部を結合する。該連結紐２０は弾力伸縮性のある紐状部材で構成したものである。該連結紐２０は、その長さ方向中央部で折り、その中央部を該係止リング１８の内部に挿入通過させた上で、該紐の連結球１９、１９を結合した側を該係止リング１８の該当する部位を巻いてその外側から該連結紐２０の中央部のＵ字形の部分の内部を通して強く引くと、該連結紐２０の中央部付近は該係止リング１８の該当する部位に巻き付き固定された状態になる。 Further, as described above and as shown in FIGS. 1, 3 (a) and 4, the locking ring 18 is joined with the central portion of the connecting string 20 having connecting balls 19, 19 connected to both ends. The connecting string 20 is constituted by a string-like member having elastic elasticity. The connecting string 20 is folded at the center in the longitudinal direction, the center is inserted and passed through the locking ring 18, and the side of the string connecting the connecting balls 19, 19 is locked. When the corresponding part of the ring 18 is wound and pulled strongly from the outside through the inside of the U-shaped part of the central part of the connecting string 20, the vicinity of the central part of the connecting string 20 becomes the corresponding part of the locking ring 18. It will be in the state fixed by winding.

従ってこの実施例の軽アイゼンによれば、その登山靴Ｓへの装着が簡単にでき、かつこれを装着して氷雪上や泥道を歩く際に滑り止めとして有効に機能すると共に、これが歩行中に前後又は左右等にずれることもなく、しかも装着手段の殆どが容易に損傷の生じない部材で構成され、外部の岩等に接触すると損傷の虞のある連結紐２０は登山靴Ｓへの装着時には、その甲の中央付近に位置し、そのような接触、そしてこれによる損傷の虞も極めて少ないので、滑落等を防止しながらより安全な歩行を確保することができる。更にはその取り外しも簡単であり、携帯及び保管にも便利である。加えて、この軽アイゼンを装着する登山靴のサイズ如何に関わらず装着が容易であり、調整が必要な場合に前記上部抱持ベルト１４はその長さの調節が可能であり、かつ極めて簡単に調節ができる。 Therefore, according to the light crampons of this embodiment, it can be easily attached to the mountain climbing shoes S, and it functions effectively as an anti-slip when walking on ice and snow or on a muddy road. The connecting cord 20 is configured with a member that is not easily displaced in the front-rear or left-right direction, and that is not easily damaged, and that may be damaged when it comes into contact with an external rock or the like. Since it is located near the center of the instep and there is very little risk of such contact and damage due to this, it is possible to secure a safer walking while preventing slipping or the like. Furthermore, it is easy to remove and convenient to carry and store. In addition, it is easy to mount regardless of the size of the mountaineering shoe to which this light crampon is mounted, and when the adjustment is necessary, the length of the upper holding belt 14 can be adjusted, and it is very simple. You can adjust.

この実施例の軽アイゼンの登山靴Ｓへの装着は次のように行う。
装着に先立って、フロントプレート１とヒールプレート２とを結合するジョイント鎖３の長さを調節しておく。これは、必要以上に長い部分をカットすることにで行うことができる。また登山靴Ｓの踵部を、両側の連結鎖６、６及びこれらを介在環７、７を介して接続する係止バー部材８によって、十分な締付力をもって締付け得るように前記連結鎖６、６の長さを適切に設定しておく。 The light crampons of this embodiment are attached to the mountain climbing shoes S as follows.
Prior to mounting, the length of the joint chain 3 that joins the front plate 1 and the heel plate 2 is adjusted. This can be done by cutting longer than necessary. Further, the connecting chain 6 can be fastened with a sufficient tightening force by the connecting bars 6 and 6 on both sides and the locking bar member 8 that connects these via the intervening rings 7 and 7 to the heel portion of the mountain climbing shoe S. , 6 is set appropriately.

このように調節した後、図１に示すように、フロントプレート１及びヒールプレート２を、前者を前に後者を後に位置させながら、その横ズレ防止ピン５、５…の立ち上がった面を上向きにして配し、この上に、図４に示すように、登山靴Ｓを載せる。図中にはこれを履いている登山者の足は描かれていないが、これは作図の都合上であって、実際には登山靴Ｓは登山者が履いた状態でこの軽アイゼンの装着を行う。 After adjusting in this way, as shown in FIG. 1, the front plate 1 and the heel plate 2 are placed so that the rising surfaces of the lateral displacement prevention pins 5, 5. A mountain climbing shoe S is placed thereon as shown in FIG. The figure does not show the feet of the climber wearing this, but this is for the convenience of drawing. Actually, the climbing shoe S is worn by the climber and this light crampon is worn. Do.

As shown in FIG. 4, at this time, the upper holding belt 14 and the side holding chains 16 and 16 on both sides connected to both ends of the upper holding belt 14 through the retaining rings 15 and 15 are lifted, and the portions surrounded by these are held. The front part of the mountain climbing shoes S is put in a charged state. When the size of the charging space is not appropriate, as described above, the length of the upper holding belt 14 is adjusted by operating the coupling rings 14b and 14c so that the size of the charging space is appropriate. Needless to say, it should be adjusted.

次いで、この状態で、図５に示すように、前記連結鎖６、６を持上げて、前記介在環７、７を介して支持されている前記係止バー部材８を登山靴Ｓの踵部の後側で、靴底部の周縁（コバ）Ｓ１上部に配置させる。このとき、登山靴Ｓの靴底部の周縁Ｓ１の該当部位の後方への張り出し量が十分にあれば、該係止バー部材８はこれに係止し、そうでない場合であっても、この部位に直方体状の踵部付属片を接着固定しておけば、これに係止することで上記周縁Ｓ１への係止に代えることができる。 Next, in this state, as shown in FIG. 5, the connecting chains 6, 6 are lifted and the locking bar member 8 supported via the intervening rings 7, 7 is attached to the heel portion of the mountain climbing shoe S. On the rear side, it is arranged on the periphery (edge) S1 of the shoe sole. At this time, if there is a sufficient amount of rearward extension of the corresponding part of the peripheral edge S1 of the shoe sole portion of the mountaineering shoe S, the locking bar member 8 is locked to this, and even if this is not the case, this part If the rectangular parallelepiped buttock attachment piece is bonded and fixed to this, it is possible to replace it with locking to the peripheral edge S1 by locking to this.

Folded forward at the top, inserted into the front gap of the front shaft portion 11b from above, extended in the front end direction below the buckle member 11, folded back above the buckle member 11, and extended upward backward Then, it is inserted into the gap behind the rear shaft portion 11a from above, and the lower portion of the buckle member 11 and the main belt member 12 are coupled in a manner of pulling backward, and the coupling is fixed.

次いで、図４に示すように、前記上部抱持ベルト１４に外装したベルト環１７をその中央に位置するように位置決め調整した上で、該ベルト環１７及びこれに係止した係止リング１８を介して該上部抱持ベルト１４に接続した連結紐２０の両端を登山靴Ｓの足首側に引っ張り、そのそれぞれ先端を前記主ベルト部材１２にベルト環２２を介して接続した連結片１３に結合する。 Next, as shown in FIG. 4, after positioning and adjusting the belt ring 17 sheathed on the upper holding belt 14 so as to be positioned at the center thereof, the belt ring 17 and the locking ring 18 locked thereto are moved. Both ends of the connecting string 20 connected to the upper holding belt 14 are pulled toward the ankle side of the mountain climbing shoe S, and the respective ends thereof are coupled to the connecting pieces 13 connected to the main belt member 12 via the belt ring 22. .

以上の該連結紐２０の両端部の該連結片１３への結合は以下のようにして行う。
該連結紐２０の両端部を引っ張って順次該連結片１３の導入スリット１３ｂを通じてその奥部に導入し、一方は左側に、他方は右側に移動させ、この後、それぞれ前方に引っ張ると、各先端部は各々連結スリット１３ａ、１３ａに導かれる。連結紐２０の両端部にはいずれも連結球１９が構成してあり、これらが該連結スリット１３ａ、１３ａの周縁部に係止することとなるため、図４に示すように、該連結紐２０の両端部は該連結片１３に係止されることになる。なお、以上の結合操作を行うに先立って該連結片１３の位置が登山靴Ｓの足首前部中央に位置するように、これを主ベルト部材１２に取り付けたベルト環２２の位置を調節しておくものとする。 The connection of the both ends of the connecting string 20 to the connecting piece 13 is performed as follows.
When both ends of the connecting string 20 are pulled and sequentially introduced into the inner part of the connecting piece 13 through the introduction slit 13b, one side is moved to the left side and the other is moved to the right side. The parts are guided to the connecting slits 13a and 13a, respectively. As shown in FIG. 4, the connecting string 20 has a connecting ball 19 formed at both ends of the connecting string 20, and these are engaged with the peripheral edges of the connecting slits 13a, 13a. Both ends of the are locked to the connecting piece 13. Prior to performing the above coupling operation, the position of the belt ring 22 attached to the main belt member 12 is adjusted so that the position of the connecting piece 13 is positioned at the center of the front part of the ankle of the mountain climbing shoe S. I shall keep it.

こうしてこの実施例の軽アイゼンの登山靴Ｓへの装着は完了である。 Thus, the mounting of the light crampons of this embodiment on the mountain climbing shoes S is completed.

なお、登山靴Ｓからこの実施例の軽アイゼンを取外す場合は、以上に説明した装着の手順と逆の操作を行えば良く、先ず、前記連結紐２０を前記連結片１３から取り外す取外す操作から始める手順が操作し易い。 In addition, when removing the light crampons of this embodiment from the mountain climbing shoes S, an operation reverse to the mounting procedure described above may be performed. First, the operation starts by removing the connecting string 20 from the connecting piece 13. The procedure is easy to operate.

以上の説明は、図４に示すように、左側の登山靴Ｓへの装着に関してのみ行ったが、この軽アイゼンは、左右の区別なく使用することができるものであり、右側の登山靴Ｓへの装着操作も左側のそれと同様に行えば良く、同様に簡単に装着できる。 The above description has been made only with respect to the mounting on the left hiking shoe S as shown in FIG. 4, but this light crampon can be used without distinction between the left and right, and the right hiking shoe S can be used. The mounting operation can be performed in the same manner as that on the left side, and can be easily mounted in the same manner.

このようにこの実施例の軽アイゼンによれば、図４に示すように、フロントプレート１及びヒールプレート２を、登山靴Ｓの足首後部側では、連結鎖６、６とこれらと介在環７、７を介して結合する係止バー部材８とで支持し、甲部側では、両側部の側部抱持鎖１６、１６とこれらを掛止環１５、１５を介して結合する上部抱持ベルト１４とで支持し、ベルト環１７、係止リング１８及び連結紐２０とベルト環２２及び連結片１３とで該上部抱持ベルト１４と主ベルト部材１２とを接続することにより、確実に登山靴Ｓに装着するものであり、登山靴Ｓの種類を問わず安全確実にしかも簡単かつスピーディに装着できるものである。 Thus, according to the light cramp of this embodiment, as shown in FIG. 4, the front plate 1 and the heel plate 2 are connected to the connecting chains 6 and 6 and the intermediate ring 7 on the rear side of the ankle of the mountain climbing shoe S. The upper holding belt is supported by the locking bar member 8 that is connected via the belt 7, and on the upper side, the side holding chains 16, 16 on both sides and the hooks 15, 15 that are connected to these. 14, and by connecting the upper holding belt 14 and the main belt member 12 with the belt ring 17, the locking ring 18, the connecting string 20, the belt ring 22 and the connecting piece 13, the mountain climbing shoes can be securely connected. It is to be attached to S and can be safely and securely attached to any type of mountaineering shoes S in a simple and speedy manner.

また、この実施例の軽アイゼンは、前記ヒールプレート２及び前記フロントプレート１の下部にスパイク４、４…を突出させてあり、これによって氷雪上や泥道に於ける滑り止めの効果が十分発揮できるのは云うまでもなく、該ヒールプレート２及び該フロントプレート１の上面に横ズレ防止ピン５、５…が立ち上がっているため、連結鎖６、係止バー部材８及び側部抱持鎖１６、１６の作用と相俟って、歩行中に該ヒールプレート２及び該フロントプレート１が前後又は左右にズレるような虞がない。それ故一層歩行の安全性が確保できるものである。 Further, in the light crampons of this embodiment, spikes 4, 4... Protrude from the lower portions of the heel plate 2 and the front plate 1, so that the effect of preventing slippage on ice and snow and in mud can be sufficiently exhibited. Needless to say, since the lateral displacement prevention pins 5, 5... Stand up on the upper surfaces of the heel plate 2 and the front plate 1, the connecting chain 6, the locking bar member 8 and the side holding chain 16, In combination with the action of 16, there is no possibility that the heel plate 2 and the front plate 1 are displaced back and forth or left and right during walking. Therefore, walking safety can be further secured.

更に前記装着手段の前後連結部を構成する連結紐２０は、装着時に登山靴Ｓの甲側足首部に配置されている前記連結片１３にその先端が結合され、登山靴Ｓの甲側上部にのみ配置されるものであるため、雪の消えたガレ場の岩や、灌木帯等での木の枝、或いは木の根等に接触する虞が低下し、その損傷の虞は非常に低いものとなる。また他のベルト部材である副ベルト部材９及び主ベルト部材１２、並びに上部抱持ベルト１４は、非伸縮性の極めて丈夫なベルト素材で構成されているため、たとえ、それらの岩などに接触するようなことがあったとしても容易に破断等の損傷を生じる虞がなく、より安全に使用できるものである。 Further, the connecting string 20 constituting the front / rear connecting portion of the mounting means is coupled at its tip to the connecting piece 13 disposed on the back side ankle portion of the mountaineering shoe S at the time of wearing, and is attached to the upper side of the mountain climbing shoe S. Therefore, the risk of contact with the rocks of the galley where the snow disappeared, the branches of trees in the shrub belt, or the roots of the trees is reduced, and the risk of damage is very low. . Further, the auxiliary belt member 9, the main belt member 12, and the upper holding belt 14, which are other belt members, are made of a non-stretchable and extremely strong belt material. Even if there is such a case, there is no possibility of causing damage such as breakage easily, and it can be used more safely.

またこの実施例の軽アイゼンは、登山靴のサイズ如何に関わらず装着が容易であり、前記したように、調整が必要な場合にも、上部抱持ベルト１４の長さを調整することにより容易にそれに対応できる。 In addition, the light crampons of this embodiment can be easily mounted regardless of the size of the mountaineering shoes, and as described above, it is easy to adjust the length of the upper holding belt 14 even when adjustment is necessary. Can respond to it.
