「産業上の利用分野」
本発明は自動車タイヤに装着するスノくイクを改良して

の快適化を計ろうとする。[Detailed Description of the Invention] "Industrial Application Field" The present invention improves snow tires attached to automobile tires to ensure safe driving and braking on icy and snowy roads, and to prevent wear and tear on the paved road surface. The aim is to prevent the occurrence of so-called car dust pollution as much as possible, and to maintain the promotion of industrial activities and make life more comfortable during the northern winter season and before and after it.
「従来の技術」
これ迄スパイクの改良は種々発表されたが、固い舗装路
面に当った時ゴム層内に引っ込み、氷雪路面では引っ込
まないと云う方式について、その製作から装着使用引抜
き交換に至る一切が確実視され然も比較的簡易低廉と思
われるものは見当らなかった。``Prior Art'' Various improvements to spikes have been announced up to now, but the method of retracting them into the rubber layer when they hit a hard paved road surface, but not retracting on icy and snowy roads, has not been studied in any way, from manufacturing to mounting, pulling out, and replacing them. Although it seems certain that this is the case, I couldn't find anything that seemed to be relatively simple and inexpensive.
「発明が解決しようとする問題点」
スパイクの改良をその材質や形状・付加物等に頼るだけ
では至難かと言える。即ち材質では周辺ゴム層の冷温差
が急且つ犬となるに従いこれに即応が困難となり、形状
・付加物等ではタイヤの方も装着用穴等の構造変更を要
したり引き抜き交換時に付加物が穴の中に残り易い等の
ほかトラブル発生を伴う傾向がうかがえる。``Problems to be solved by the invention'' It can be said that it is extremely difficult to improve spikes by relying solely on their material, shape, additions, etc. In other words, in terms of materials, as the temperature difference between the surrounding rubber layer becomes sudden and large, it becomes difficult to respond quickly, and in terms of shape and additions, it is necessary to change the structure of the tire, such as mounting holes, and when the tire is pulled out and replaced, additions may be removed. It seems that there is a tendency for troubles to occur, such as the tendency to remain in the holes.

設けようとするものである。``Means for Solving the Problems'' The present invention separates the conventionally integrated spike into two parts, the shank and the flange, and enables the shank to move for a predetermined length within seven lunges. A spring is installed between the shank and the flange so that when the shank hits a hard paved road surface, it retracts into the flange by a predetermined length, and when it does not, it is pushed out from the flange by a predetermined length to form an approximately conventional shape.・The idea is to install a strut horn mechanism that restricts movement to a predetermined length by arranging rubber or the like.
「作 用」
圧雪面や凍結面と露出した舗装路面が混じっている一般

クがフランジ内に引っ込み易く且つフランジ外に押し出
され易いようなテーパーをシャンクに付しである。``Function'' On general roads where there is a mixture of compacted snow or frozen surfaces and exposed paved roads, the shank is likely to be moved in and out of the flange quickly and frequently over a specified length, so the resistance friction from the rubber layer surrounding the shank also increases. Become a dog and win. To avoid this, the shank is tapered so that it can easily be retracted into the flange and pushed out of the flange.
