産業上の利用分野
本発明は、必要のないときはスパイクがタイヤ内に引き
込むようにしたスパイクタイヤに関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a spiked tire in which the spikes are retracted into the tire when not needed.
従来の技術
従来のスパイクタイヤは、スパイクが常時突出した固定
構造になっており、積雪時以外に使用すると路面を傷つ
けて粉塵公害を起こし、大きな社会問題となっている。Conventional technology Conventional spiked tires have a fixed structure in which the spikes protrude at all times, and when used outside of snowy conditions, they damage the road surface and cause dust pollution, which has become a major social problem.
この問題を解決するために、近時スパイクを形状記憶合
金で製作し、一定温度以上になるとタイヤ内にスパイク
が引き込むようにしたものが提案されている。In order to solve this problem, it has recently been proposed that spikes are made of a shape memory alloy so that they retract into the tire when the temperature exceeds a certain level.
発明が解決しようとする問題点
しかしながら、形状記憶合金でスパイクを製作すると高
価になる欠点があり、実用上未だ粉塵公害を回避するま
でに至っていない。Problems to be Solved by the Invention However, manufacturing spikes using shape memory alloys has the disadvantage of being expensive, and dust pollution has not yet been avoided in practice.
本発明は、上記実情に鑑み創案されたものであって、必
要のないときはスパイクがタイヤ内に引き込み、使用時
には自由にタイヤの踏み面から露出させることが出来、
しかもその露出量が自在に調整でき、そして形状合金製
に比べて安価に製作することが出来るスパイクタイヤを
提供することを目的とする。The present invention was devised in view of the above circumstances, and allows the spikes to be retracted into the tire when not needed, and to be freely exposed from the tire tread when in use.
Moreover, it is an object of the present invention to provide a spiked tire whose exposure amount can be freely adjusted and which can be produced at a lower cost than those made of shaped alloys.
問題点を解決するための手段
上記問題点を解決するために種々研究した結果空気槽を
設けて、該空気槽の圧力差により、スバイクをタイヤ面
から出入させることを知得し、本発明に到達したもので
ある。Means for Solving the Problems In order to solve the above problems, as a result of various researches, it was learned that an air tank is provided and the bike is moved in and out from the tire surface by the pressure difference in the air tank, and the present invention has been made. It has been reached.
即ち、本発明のスパイクタイヤは、タイヤ外周ゴム部に
、下端に刃部を有し上部に受圧板を有する内函と、該内
函が摺動自在に嵌合された外函とからなるスパイク体を
配設すると共に、該スパイク体の上部のゴム部内部に空
気槽を設けてなり、該空気槽内の圧力差により前記刃部
がタイヤ外周から出入することを特徴とする構成を採用
したものである。That is, the spiked tire of the present invention includes a spike comprising an inner case having a blade portion at the lower end and a pressure receiving plate at the upper end, and an outer case in which the inner case is slidably fitted to the outer peripheral rubber part of the tire. In addition to the spike body, an air tank is provided inside the rubber part at the top of the spike body, and the blade part moves in and out from the outer periphery of the tire due to a pressure difference in the air tank. It is something.
作用
空気槽に空気を注入して空気槽が膨張すると、内函の上
面に固定されである受圧板が空気槽に押され、内函が外
函内部を摺動して、刃部がタイヤ外部に突出してスパイ
クとなる。従って、空気槽への空気注入量を調整するこ
とによって、刃部の突出量を調整することができる。When air is injected into the working air tank and the air tank expands, the pressure receiving plate fixed to the top surface of the inner case is pushed by the air tank, the inner case slides inside the outer case, and the blade part touches the outside of the tire. It becomes a spike that sticks out. Therefore, by adjusting the amount of air injected into the air tank, the amount of protrusion of the blade portion can be adjusted.
そして、必要のないときには空気槽の空気を抜き圧力を
下げれば、空気槽の収縮により引き上げられ、刃部は踏
み面内部に引き込まれる。Then, when it is not needed, if the air in the air tank is removed and the pressure is lowered, the blade will be pulled up by the contraction of the air tank and the blade will be drawn into the inside of the tread surface.
実施例

である。FIG. 1 is a cross-sectional view of a spiked tire according to an embodiment of the present invention, in which the right side from the center line shows a state where the spike is retracted into the tread surface, and the left side shows a state where the spike is exposed from the tread surface. In the figure, 1 is a tire, and the outer peripheral rubber (
A steel spike body 3 is built into the tread surface. The spike body 3 has an inner case 5 having a blade part 6 at the lower end and a pressure receiving plate 7 at the upper end, and an outer case 8 into which the inner case is slidably inserted. Lower lead wire 11゜1
2 are provided as shown in FIG. A pole bearing 13 is arranged on the sliding surface of the outer case 8 and the inner case 5 to facilitate sliding.

Upper lead wires 16 are embedded vertically and horizontally between the air tank 15 and the inner screen of the tire, and a vertical lead wire 18 connects the lead wires 16 and the lower lead wire 11 inserted through the bracket. It is fixed.

remains within the tread surface. When air is injected into the air tank 15 and the air tank 15 expands, the inner box 5
The pressure receiving plate 7 fixed to the upper surface of the tire is pushed, the inner case 5 slides inside the outer case 8 via the bearing 13, and the blade part 6 protrudes to the outside of the tire to become a spike. Since the lower lead wires 11, 12 and the upper lead wire 16 are connected by the vertical lead wire 18, the volume fluctuation of the air tank 15 due to the weight of the vehicle is suppressed, and the spikes are fixed. Works the same way. Therefore, by adjusting the amount of air injected into the air tank 15, the amount of protrusion of the blade portion 6 can be adjusted.
そして、必要のないときには空気槽の空気を抜−苧一
き圧力を下げれば、空気槽の収縮により引き上げられ、
刃部６は踏み面内部に引き込まれる。Then, when it is not needed, the air in the air tank is removed and the pressure is lowered.
The blade portion 6 is drawn into the inside of the tread surface.
以上は本発明の一実施例を示したが、本発明は該実施例
