本発明は超硬ピンを有する滑り止め片に係わり、タイヤ
のトレッド部分に脱着的に装着して、自動車走行中のタ
イヤの滑りを防ぐ滑り止め片の作り方に関する。Detailed Description of the Invention (Industrial Application Field) The present invention relates to an anti-slip piece having a carbide pin, which is detachably attached to the tread of a tire to prevent the tire from slipping while the car is running. Concerning how to make a stopper piece.
（従来の技術）

わってタイヤのトレッド面に脱着できる超硬ピンを有す
る滑り止め片が用いられるようになった。(Prior Art) As is well known, anti-slip means are attached to the tires of vehicles to prevent them from slipping when driving on snowy or icy roads. In the past, tire chains were often used, but later on, spiked tires came to be used due to the inconvenience of attaching and detaching them. However, due to the harmful effects of dust, etc., anti-slip pieces having carbide pins that can be attached to and removed from the tire tread surface have recently been used instead of the tire chains and spiked tires mentioned above.
即ち、ゴム、又はプラスチックなどに超硬ピンをピン部
分のみ表面に露出するようにして埋め込まれている滑り
止め片が使われている。That is, an anti-slip piece is used in which a carbide pin is embedded in rubber or plastic with only the pin portion exposed to the surface.

する為に次の方法によって製造されているのが現実であ
る。Now, if we look at the conventional manufacturing method of the anti-slip piece having this carbide pin, as shown in Figures 5 and 6, when molding the anti-slip piece of rubber or plastic, a super A hole for embedding the hard pin 5 is made and molded, and then the flange part 5C, shank part 5b and pin part 5 prepared in advance are made.
It was manufactured by embedding a carbide pin 5 made of a material into the embedding hole 6. In this case, as a matter of course, the flange portion 5C of the carbide pin 5 was embedded so as to be located at the bottom of the embedding hole 6, leaving only the pin portion 5a exposed on the surface. In this case, the molded rubber piece 7 once expands due to its ductility when press-fitted, and returns to its original state due to the elastic restoring force of the rubber when it is completely set, so that the carbide pin 5 is fixed there. However, a problem has arisen in which the carbide pin 5 falls out of the embedded hole 6 when the vehicle is driven for a long time. Therefore, the reality is that conventionally, carbide pins have been manufactured by the following method in order to prevent them from falling out.
第７図、第８図に示したように、超硬ピン８をフランジ

形し製作しているものであった。As shown in FIGS. 7 and 8, it is natural that the carbide pin 8 is formed of a flange portion 8C, a shank portion 8b, and a pin portion 8a, but the flange is a double 7 flange 8C, and the carbide pin 8 When a plurality of are lined up in a predetermined arrangement, the wire 9 is crossed over the flange portion 8C to pass the rack, the carbide pins 8 are held in mutual position, and then set in a rubber mold or plastic mold. However, the carbide pin 8 was manufactured by vulcanization or injection molding, with only the pin portion 8a of the carbide pin 8 exposed on the surface.

常に手間がかかるものであった。(Problems to be Solved by the Invention) According to the above-mentioned prior art, since each of the carbide pins embedded in the anti-slip piece made of rubber or plastic is connected to each other with a wire, It is true that compared to the press-fit type, the carbide pin has the advantage of not falling out when extracted. However, although it is possible to automatically pass the wire between each double flange, the equipment is expensive and requires a lot of effort.

Particularly, it is an object of the present invention to provide a manufacturing method that can produce a non-slip piece that is easy to manufacture using an automated process or that can be supplied to the market at low cost.

。In FIGS. 1 and 2, 1 indicates a carbide pin, and the carbide pin has the following configuration. That is, a so-called pin-type carbide pin is shown in this example, in which a flange portion 1c is formed at the bottom, a shank portion tb is integrally provided on the top, and a pin portion 1a is planted on the shank portion. has been done. Prepare a plurality of these carbide pins 1, prepare a very thin metal plate, specifically, an iron plate 2 of about 0.5~law, and arrange the plurality of carbide pins 1 appropriately. For example, it is shown in FIG. Then, these carbide pins 1 are fixed to an iron plate 2. Several examples can be given of the fixing method. One method is to use spot welding, or the flange portion IC of the carbide pin 1 and the iron plate 2 are both made of iron, so they can be fixed 17 using a strong adhesive that easily adheres to each other.

Furthermore, when this is embedded in a mold made of rubber or plastic, each carbide pin l is inserted into the metal plate 2.
Since they are connected with each other, they are prevented from falling off. By the way, when this anti-slip piece is attached to the tread of a tire, it is forced to curve during driving. However, if the metal plate 2 is made extremely thin, it can withstand this problem.

。(Effects) As described in detail below, according to this invention, since each carbide pin is connected by a metal plate, it is of course possible to effectively prevent the carbide pins from being pulled out or falling. In order to connect each carbide pin, a metal plate is used, but the connection is done by an easy method such as spot welding, and the flange part of the carbide pin needs to be made into a double flange. This method has the advantage that it can be supplied to the market at a low cost because it requires less investment in equipment and labor costs for processing, welding, manufacturing, etc. compared to conventional manufacturing methods.
