Description

  The present invention relates to a sports shoe, and more particularly to a shoe in which a spike pin can be made to appear and disappear from the entire sole surface.

  In sports shoes such as golf shoes, spikes or spike pins are provided on the sole so that the ground is firmly gripped during the swing of the golf club and the foot does not slip.

  However, conventional metal spikes and spike pins may leave spike marks on the lawn when walking on the green, which may hinder subsequent players from playing smoothly. Further, when walking on the asphalt surface in the golf course, there is a feeling of pushing up and instability, and further, the impact from the asphalt surface is transmitted from the sole of the foot to the knees and waist, resulting in a great feeling of fatigue. Also, walking in the clubhouse can damage the floor.

  On the other hand, instead of metal spikes and spike pins, synthetic resin spikes and spike pins, so-called “non-metal spikes” have been adopted (Patent Document 1, Patent Document 2). Spikes and spike pins have a small grip force on a golf course, and for example, there is a possibility that the feet slip on a wet lawn or a dry lawn.

  On the other hand, sports shoes in which spike pins made of metal or hard resin are made to appear and disappear from the sole have been proposed (Patent Documents 3 and 4).

  However, the sports shoes described in Patent Documents 3 and 4 have a structure in which the operating lever and the slider or cam are connected to displace the slider or the cam so that the spike pin protrudes and retracts. However, it is difficult to adopt a structure in which the location of the operation lever is limited and the spike pin is made to appear and disappear on the entire sole surface.

  This invention makes it a subject to provide the sport shoes which made it possible to make the spike pin appear and disappear from the sole whole surface in view of this problem.

  Therefore, in the sports shoes according to the present invention, a plurality of insertion holes are formed in the sole, hard spike pins are slidably inserted into the plurality of insertion holes, and the plurality of spike pins are prevented from coming down downward. In addition, a slide cam that is urged upward by a spring member and is in contact with the heads of the plurality of spike pins is provided in the sole, and the plurality of slide cams are connected by a wire and an operation lever is operated. As a result, the slide cam is pulled through the wire and slid between the first position and the second position, and the slide cam projects the tip of the spike pin downward at the first position. The above-mentioned spike pin is immersed.

  One of the features of the present invention is that a spike pin is slidably provided on the entire sole surface, a slide cam is provided above the spike pin, a plurality of slide cams are connected by a wire, and the wire is pushed and pulled by an operation lever. It is in the point where the spike pin is made to appear and slide by sliding.

  As a result, the spike pin provided on the entire surface of the sole can be caused to appear and disappear regardless of the position of the operation lever.

  Only a hard spike pin may be provided on the sole, but an appropriate soft resin spike is provided so that an appropriate grip force can be obtained even when the spike pin is immersed. It is recommended to make the spike pin appear.

  That is, a plurality of mounting holes are formed in the sole, resin spikes are inserted and fixed in the plurality of mounting holes, an insertion hole is formed in the center of the plurality of resin spikes, and a hard spike pin is formed in the insertion hole Is configured so that the tip of the spike pin protrudes downward from the lower end of the resin spike at the first position, and the tip of the spike pin is inserted into the resin spike at the second position. It is preferable to do this.

  It is necessary to provide a space for laying out the slide cam, wire, and operation lever in the sole. Therefore, it is preferable that the sole is composed of a lower sole and an upper sole, and a space capable of accommodating a slide cam, a wire, and an operation lever is formed between the lower sole and the upper sole.

  When the spike pins are laid out over the entire sole surface, the wires connecting the slide cams may be bent and laid out. Therefore, it is preferable to provide a guide for guiding the movement of the cable in the space. For example, a guide roller can be adopted as the guide.

  The material of the spike pin is not particularly limited as long as it has a predetermined hardness. For example, the spike pin can be manufactured using a metal material or a hard synthetic resin material, and a metal core is covered with a synthetic resin material. It can also be produced.

  The slide cam needs only to be able to slide the spike pin by sliding the head of the spike pin on its cam surface, but the cam surface should be held on the spike pin head so that the spike pin can be held in the protruding state and the immersed state. It is preferable to form in a concave shape to fit.

  Hereinafter, the present invention will be described in detail based on specific examples shown in the drawings. 1 to 3 show a preferred embodiment of a sports shoe according to the present invention, which is an example applied to a golf shoe. In the figure, a shoe 10 is provided with a mouth 11, a collar 12 is provided in front of the mouth 11, a shoelace 13 is hung on the eyelet between both sides of the collar 12, and the shoe 10. A sole 20 is fixed to the bottom of the base plate. In addition, although not illustrated above the sole 20, an inner sole (sole) may be further provided.

  The sole 20 is configured by laminating a lower sole 21 and an upper sole 22 and fixing them together, and the lower sole 21 and the upper sole 22 are manufactured by using, for example, an injection molding method using a synthetic resin material such as nylon or urethane.

  The lower sole 21 has five circular attachment holes 21A formed at the front and two rear portions along the outer edge of the sole 20. A female screw is formed on the inner surface of the attachment hole 21A, and a spike 30 is formed in the attachment hole 21A. A male screw is screwed and attached.

  The spike 30 is manufactured by using, for example, an injection molding method using a synthetic resin material such as nylon or urethane, and has a configuration in which a plurality of protrusions 30B are projected at equal angular intervals on the outer edge of the bottom surface of the circular base 30A. An insertion hole 30 </ b> C is drilled in the center in the vertical direction.

  A spike pin 31 is slidably inserted into the insertion hole 30C of the spike 30, and the spike 31 is made of a metal material such as stainless steel, has a cylindrical shape with a sharp tip, and a rear end at the rear end. The head portion 31A is formed with an enlarged diameter, and the spike pin 31 is prevented from coming down by the head portion 31A hitting the periphery of the insertion hole 30C.

  A small-diameter portion is formed in the middle of the spike pin 31, and a coil spring (spring member) 32 is provided on the outer periphery of the small-diameter portion. The lower end of the coil spring 32 is formed by a protrusion (not shown) on the inner surface of the mounting hole 30C. Positioned and locked, the spike pin 31 is urged upward.

  Further, a groove (space) 22A is formed in the upper sole 22 in a shape along the outer shape of the sole 20, and a slide groove 22B is formed in a portion corresponding to the spike pin 31 in the groove 22A. Is slidably arranged.

  The slide cam 23 has two cam surfaces 22A and 23B. One cam surface 23A has a small thickness, and the tip of the spike pin 31 is immersed in the spike 30 when the slide cam 23 is slid to the second position. The other cam surface 23B has a large thickness, and when the slide cam 23 is slid to the first position, the tip of the spike pin 31 protrudes downward from the lower end of the protrusion 30B of the spike 30.

  The plurality of slide cams 23 are connected by a wire 24, and a guide roller (guide) 25 for guiding the wire 24 is provided at a corner portion of the concave groove 22A.

  A storage recess 22C extends in the width direction at a portion corresponding to the arch of the upper sole 22, and an operation lever 26 is stored in the storage recess 22C. A distal end portion of the operation lever 26 is rotatable to the upper sole 22. The wire 24 is connected to the operation lever 26 so that the wire 24 is endless, and a knob 26A of the operation lever 26 projects outward from the sole 20.

  When the player swings the golf club, the slide cam 23 is slid to the first position by operating the knob 26A of the operation lever 26. Then, the cam surface 23B of the slide cam 23 comes into contact with the head portion 31A of the spike pin 31, slides the spike pin 31 downward, and the tip of the spike pin 31 protrudes from the spike 30 as shown in FIG. Since it projects below 30B, the golf club ground can be securely gripped by the entire sole 20 and the golf club can be swung strongly.
