Description

本発明は、岩盤上や氷上を歩行するのに好適であるとともに、通常の地面を歩行するのにも好適な杖に関するものである。 The present invention relates to a cane that is suitable for walking on rock and ice, and also suitable for walking on normal ground.

従来より、岩盤上や氷上を歩行する目的と通常の地面を歩行する目的の両方に役立つ杖が知られている（たとえば、特許文献１，２参照）。これらの杖は一本で岩盤上や氷上を歩行するための鋭利な岩盤用先端部分と通常の地面を歩くための樹脂あるいは硬質ゴムからなる丸みのある通常用先端部分とが選択的に切り換えられて使われるものである。 Conventionally, a cane that is useful for both the purpose of walking on a rock or ice and the purpose of walking on a normal ground is known (for example, see Patent Documents 1 and 2). These canes selectively switch between a sharp rock tip for walking on rock and ice and a normal tip with a round shape made of resin or hard rubber for walking on the normal ground. It is used.

これらよく知られた杖は、先端に硬質ゴムからなる接地部をもつ杖本体と杖本体の接地部付近に回動自在に取り付けられたレバーとレバーの他端に取付けられた円錐状の岩盤用先端部分とからなるもので、レバーを回動させることにより、鋭利な岩盤用先端部分を硬質ゴムからなる通常用先端部分の直下に位置させるものである。また、岩盤用先端部分が通常は本体からはずれており、用途に応じて硬質ゴム等の通常用先端部分に嵌合装着されるものもよく知られている。 These well-known canes are for a cane body with a grounding part made of hard rubber at the tip, a lever that is pivotally mounted near the grounding part of the cane body, and a conical bedrock that is attached to the other end of the lever. It consists of a tip portion, and by turning the lever, the sharp tip portion for rock is positioned directly below the tip portion for normal use made of hard rubber. It is also well known that the rock tip is normally detached from the main body, and is fitted to the tip end for normal use such as hard rubber depending on the application.

しかし、上記従来の杖では、岩盤用先端部分がレバーにより本体に取付けられているものの場合、通常の歩行中、岩盤用先端部分が本体外部にあるため危険であったり、また、レバーによる切り換えが複雑かつ壊れやすく、さらに高価であるといった欠点があった。また、岩盤用先端部分が通常、本体からはずれているものの場合、装着してもはずれやすくまた紛失しやすいといった欠点があった。 However, in the above-mentioned conventional cane, when the rock tip is attached to the main body by a lever, it is dangerous because the rock tip is outside the main body during normal walking, and switching by the lever is not possible. It has the disadvantages of being complicated, fragile and expensive. Moreover, when the tip part for the bedrock is usually detached from the main body, there is a drawback that it is easy to come off even if it is attached and is easily lost.

Since the method of assembling the first cane body 11 and the second cane body 12, the method of assembling the second cane body 13 and the third cane body, and the method of assembling the grip 30 to the first cane body 11 are well known, they are omitted here. To do.
First, one end of the shaft 14 is press-fitted into the third cane body 13. Then, the coil spring 17 is inserted into the shaft 14, and then the movable part 16 is inserted in the direction in which the contact parts 16b and 16c come to the main body side. Then, the movable portion 16 is pressed to press the coil spring 17 and the pin 15 is press-fitted into a hole provided in the shaft 14 so as to be in the two notches 16a. At this time, the coil spring 17 always has a sufficient elastic coefficient so that the two contact portions 16 b and 16 c of the movable portion 16 are pressed against the pin 15 with sufficient strength.

（３）杖の作用
以下に図５を参考にしながら本実施例の作用について説明する。
通常、杖１を使用しないときは、第１杖本体１１の中に第２杖本体１２がたたみ込まれ、第２杖本体１２の中に第３杖本体１３がたたみ込まれ、持ち運びが便利な長さになっている。通常の地面を歩行する際には、杖１は十分な長さに伸ばされ、可動部１６の切り欠き１６ａの第１当接部１６ｂがピン１５にコイルばね１7の弾性力によっておしつけられ、軸１４の接地部１４ａは可動部16、即ち筒状先端部３０の中に隠れる。この状態で杖1を使用すると地面にはゴム製の筒状先端部３０の下面があたり、杖1が滑ることなくスムーズに歩行できる。岩盤上や氷上を歩行する際には、筒状先端部３０を把持して、この筒状先端部３０と共に可動部16をコイルばね17の弾性力に抗して軸方向に押し付け、切り欠き１６ａの第２当接部１６ｃがピン１５に当接するように可動部の位置を変更する。こうすると、軸１４の接地部１４ａが筒状先端部３０の下面より突出される。この状態で杖１を使用すると岩盤あるいは氷には接地部１４ａの先端があたるため、やはり杖１が滑ることなくスムーズに歩行できる。また、再び通常の地面に使ったり、使用を止める際にはピン１５が第２当接部１６ｃから第１当接部１６ｂにあたるように切り換える。 (3) Operation of Cane The operation of the present embodiment will be described below with reference to FIG.
Usually, when the cane 1 is not used, the second cane body 12 is folded into the first cane body 11, and the third cane body 13 is folded into the second cane body 12, which is convenient to carry. It is length. When walking on the normal ground, the cane 1 is extended to a sufficient length, and the first abutting portion 16b of the notch 16a of the movable portion 16 is applied to the pin 15 by the elastic force of the coil spring 17 and the shaft The 14 grounding portions 14 a are hidden in the movable portion 16, that is, the cylindrical tip portion 30. When the cane 1 is used in this state, the lower surface of the rubber cylindrical tip 30 hits the ground, and the cane 1 can walk smoothly without slipping. When walking on rock or ice, the cylindrical tip 30 is gripped, and the movable portion 16 is pressed together with the cylindrical tip 30 against the elastic force of the coil spring 17 in the axial direction, thereby forming a notch 16a. The position of the movable portion is changed so that the second abutting portion 16 c abuts on the pin 15. As a result, the grounding portion 14 a of the shaft 14 protrudes from the lower surface of the cylindrical tip portion 30. When the cane 1 is used in this state, the tip of the ground contact portion 14a hits the rock or ice, so that the cane 1 can walk smoothly without slipping. Further, when using again on the normal ground or stopping the use, the pin 15 is switched from the second contact portion 16c to the first contact portion 16b.

（４）本実施例の効果
本実施例による杖１を使用すれば、通常の歩行の場合には鋭利な接地部１４ａがかくれているため、安全性にすぐれ、また、構造が簡単なので壊れにくく、しかも安価である。さらに、部品の脱着がないため、部品を紛失することがない。 (4) Effects of the present embodiment If the cane 1 according to the present embodiment is used, the sharp grounding portion 14a is hidden in normal walking, so that the safety is excellent and the structure is simple and is not easily broken. And it is cheap. Furthermore, since there is no detachment of parts, parts are not lost.
