【考案の詳細な説明】
［産業上の利用分野］
本考案は冬山登山、特に氷壁登攀に使用するピ
ツケルの改良構造に関するものである。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an improved structure of a pickkel used for winter mountain climbing, especially ice wall climbing.
［従来の技術］
従来、ピツクの先端部分を半円状のチユーブと
したピツケルは知られている。[Prior Art] Pickels in which the tip of the pick is a semicircular tube have been known.
［考案が解決しようとする問題点］
ところで、この種のピツケルは、ピツクを氷壁
に打込んだときにチユーブ内に氷片が詰まつた
り、空気が籠るために氷層へのくい込みが悪くな
り、その結果、必要十分なアンカーポジシヨンが
得られずスリツプを起こしたり、滑落事故につな
がる虞れがあつて、いま一つ安全面で問題があつ
た。[Problems that the invention aims to solve] By the way, when this kind of pickle is driven into the ice wall, the tube gets clogged with ice chips, and air gets trapped, making it difficult to penetrate into the ice layer. As a result, the necessary and sufficient anchor position could not be obtained and there was a risk of slipping or falling accidents, which caused another safety problem.
本考案は、上記事情にかんがみて創案されたも
のである。 The present invention was devised in view of the above circumstances.
［問題点を解決するための手段］
本考案は、先端部分を半円状のチユーブとした
ピツクを備えるピツケルにおいて、チユーブ部分
に小孔を穿設して成る。[Means for Solving the Problems] The present invention is a pick that includes a pick whose tip portion is a semicircular tube, and a small hole is bored in the tube portion.
［作用］
ピツクを氷壁に打込んだ際に、半円状のチユー
ブ内に詰まる氷片や空気が小孔から押し出され
る。これによつて、ピツクが氷壁にしつかりくい
込み、登攀を安全かつ容易とする。[Operation] When the pick is driven into the ice wall, ice chips and air stuck in the semicircular tube are pushed out through the small hole. This allows the pick to cling to the ice wall, making climbing safe and easy.
［実施例］
図において、１は所要長さのシヤフト２の上端
に一方をハンマー３とし、他方をピツク４とした
ヘツド５を取付けたピツケルであり、シヤフト２
の下端にはシユピツツエ６が取付けられている。[Example] In the figure, 1 is a pickle with a head 5 attached to the upper end of a shaft 2 of a required length, one with a hammer 3 and the other with a pick 4.
Shupitsue 6 is attached to the lower end of.
ピツク４は、先端部分に下面で開口した半円状
のチユーブ７が形成され、両側開口縁は鋸歯状に
カツトされている。 The pick 4 has a semicircular tube 7 opened at the bottom at its tip, and edges of the opening on both sides are cut into a sawtooth shape.
而して本考案によれば、前記チユーブ７の頂部
部分に２個の小孔８，８を適当間隔を離して前後
位置に突設する。 According to the present invention, two small holes 8, 8 are provided in the top portion of the tube 7 so as to protrude from the front and back at an appropriate distance.
このように構成された本考案のピツケルは、ピ
ツク４を氷壁に打込んだ際に小孔８，８が排出口

め、チユーブ７内に詰まる氷片や空気による打ち
込み抵抗が減少されることになり、氷層に十分に
喰い込んで安全なアンカーポジシヨンが得られ、
スリツプや滑落事故の発生が防止できる。 The pickle of the present invention constructed in this way has the small holes 8, 8 acting as an outlet when the pick 4 is driven into the ice wall, so that the ice chips and air stuck inside the tube 7 are released from the tube 7. being pushed out. For this reason, the driving resistance due to ice pieces and air that get stuck in the tube 7 is reduced, and a safe anchor position is obtained by sufficiently biting into the ice layer.
This can prevent slips and falls from occurring.
なお、実施例では小孔８を二個設けているが、
１個でも良く、またチユーブ７部分の強度を損ね
ない限り数を増したり、孔径を大きくすることで
本考案の効果を一層高めることができる。 In addition, although two small holes 8 are provided in the example,
The effect of the present invention can be further enhanced by increasing the number of holes or increasing the hole diameter as long as the strength of the tube 7 portion is not impaired.

等その実用価値はきわめて大である。[Effects of the invention] As described above, the pickle of the present invention has small holes 8, 8 bored in the semicircular tube 7 provided at the tip of the pick. Ice chips and air stuck in the groove are pushed out, significantly increasing penetration and providing strong support. Therefore, its practical value, such as the ability to safely climb ice walls, is extremely great.
