Description

Sole construction with multi-material cleats

technical field

The utility model relates to a shoe sole structure with multi-material shoe claw nails, which is related to the shoe claw nails of the shoe sole.

Background technique

Existing shoe nails, or called foot nails or claw nails, are mostly configured on the soles of golf shoes, mainly for the purpose of providing shock absorption, improving grip or improving controllability, as shown in Figure 1. However, existing shoes The sole 10 of the claw nail has the following disadvantages. The shoe sole 10 is combined with a plurality of shoe claw nails 11 made of metal material, and the shoe claw nails 11 are screwed to the sole 10. not shown), and such a manufacturing process is not only cumbersome and not conducive to mass production, but at the same time, the shoe sole 10 will cause a torsion effect on the claw nails 11 of the shoe sole 10 no matter when it is walking normally or doing a large range of motion. Cause the rotation of the claw nails 11, so that after a period of time, the shoe claw nails 11 will be loosened from the sole 10, and the process of manufacturing the shoe sole 10 needs to be implanted with metal nuts for production, so that the shoe The claw nails 11 can be rotated and locked in, leading to water seepage of the sole 10 due to long-term use;

Therefore more a kind of manufacturing method of the shoe sole that has plastic shoe claw nail comes out, but has following shortcoming equally, plastic shoe claw nail is changed by plastic injection by metal material, reduces material cost and improves production efficiency, but because of its mold structure problem its sole still needs The plastic shoe nails can be locked into the sole by implanting metal nuts for injection production. The water seepage problem still needs to be improved, and the position of the plastic shoe nails on the sole needs to be placed due to the injection of metal nuts. Restricting the distance between the claws and the claws is functionally unable to meet changes in user needs;

There is also a shoe sole with rubber claw studs. The sole is made of plastic, and the spikes are made of rubber. Because the forming conditions and methods of rubber and plastic are different, general forming methods cannot simultaneously form rubber. And plastic, so it must be preformed separately and then glued or bonded separately, and if the uniformity of the glue is not really controlled during the glue application, the lack of bonding stability may occur;

The shape and structure of existing claw nails are limited, because the manufacturing methods are all the same, and the claw nails are locked into the sole by rotation, so the mold release method of the claw nails also needs to be rotated to take out the shoe claws The finished product, the manufacturing method here has a great influence on the shape design of the claw nails. One is that the shoe claw nails can only arrange the positions of the claws in a concentric circle array, and the other is that if the shoe claw nails need to be rotated to lock into the sole , the sole must be implanted with a nut and then injected, and the thickness of the sole will increase the thickness of the nut;

And the sole needs to be implanted with a nut and then injected. When the nut is embedded in the mold of the sole, it needs to be fixed by a thimble. Therefore, the hole of the thimble will be left after the sole is shot, which will easily cause water seepage after the claw nail is rotated and locked.
