Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention mainly relates to a shoe sole which is required to have an anti-skid effect and prevent thrusts in outdoor sports, for example, short-distance competition, baseball, golf, and the like. The present invention relates to a shoe sole for sports shoes which is provided with a spike in a state where it is projected.

[0002]

[Prior art]

 Conventional spikes for sports shoes, especially spikes for golf shoes, have a configuration in which the spike pins protrude to the ground contact surface and are fixed to the soles of the shoes so that they do not protrude and disappear in the piercing direction of the spike pins. On a golf course with a downed golf course, the landing posture is large, and if the ground surface is hard, the thrust is large, pain is applied to the back of the leg, slippage occurs, and walking fatigue is severe. there were. This is the case in other sports, though to varying degrees.

[0003] In order to reduce the thrust and facilitate walking, for example, as disclosed in Japanese Patent Application Laid-Open No. 10-104, a male screw which is screwed with a female screw inserted into a sole member is disclosed. A cylindrical body having a screw formed thereon is protruded from one side of a seat plate having a pin hole formed at the center, and a spike pin is passed through the pin hole from the cylindrical body, and a rear end of the spike pin is provided with an elastic machine ( Japanese Patent Laid-Open No. 10-105 discloses a spike for shoes in which the male screw of the tubular body is screwed so as to be detachable from the female screw in which the male screw is pushed by an elastic material such as a coil spring or rubber. As disclosed in the official gazette, there is known a structure in which a spike pin assembly incorporated so as to be protruded and retracted by the action force of an ammunition is inserted into a sole member of a shoe, and in each case, the spike pin assembly is used to reduce the action force of the ammunition The strong acting force of the spike pin If the tip is received, the spike pins retract and act to mitigate the thrust from the ground contact surface.

[0004]

[Problems to be Solved by the Invention] However, in the conventional spikes for golf shoes described above, since a single spike pin applies a projecting force to the single spike pin by a bullet, it is stronger than the bullet. When the acting force acts on the tip of the pin, the pushing force can be reduced to some extent, but the acting force exceeding the relaxed force acts intensively on the sole via a single spike pin. Therefore, there is a common problem that not only pain is often accompanied by walking, but also slipping because the immersed spike pin does not provide any slipping effect. Since the entire material is inserted in a non-watertight state and cannot be removed, it can be easily broken due to rust of the armature due to water intrusion, fatigue due to repeated expansion and contraction, and infiltration of fine sediment. By leading to inhibition of movement of the studs, and it can no longer sufficiently achieve the desired effect, it is repaired there is a problem in that extremely difficult.

[0005] The present invention not only disperses and alleviates the pushing-up force, but also secures a slipping effect to ensure safe and low-fatigue walking, and is excellent in durability and easily as required. It is an object of the present invention to provide a shoe sole for sports shoes that can be restored in function.

FIG. 4 is a partial cross-sectional view of a state in which it is screwed into the bottom member (3). The medium-hard synthetic resin, for example, a thermoplastic polyurethane resin “Elastoran” ET-195 (hardness 95A / JIS) A) consisting of a bottom member (3) with a metal (stainless steel) nut (2) embedded at the position where the spike (1) is screwed in and fixed, and a spike (1) screwed into the nut (2). And a ring packing (6) interposed in a threaded portion between the bottom member (3) and the spike (1).

The spike (1) has a screw leg (8) integrally formed at the center thereof so as to protrude therefrom, and is integrally formed on a concentric circle around the screw leg (8) at intervals of 120 degrees. A cylindrical portion (15) through which the insertion hole (9) penetrates, and an aluminum alloy seat core (51) having an outer diameter of 18 mm having a notch hole (14) for fastening formed between the cylindrical portion (15). In addition, the pin insertion hole (9) is ensured to penetrate, the notch hole (14) for tightening is secured to the ground plane side, and the pin insertion hole (9) opened to the ground plane side is penetrated. A transparent urethane member (52), which is a jacket member covered around a cylindrical portion (15) to be surrounded by a bulged portion (12) having a height of about 2 mm and a flat ellipse, and a spike at the tip. An end and a rear end are formed of a cemented carbide formed on a seal contact flange (11), for example, three cermet rod-shaped spike pins (10), and the seat core (51) is By means of insert molding It is buried in the urethane member (52), and only the screw legs (8) protrude without being covered to form a spike seat plate (5). Is inserted to strengthen the integrity of the resin and metal, and the insertion port of the tightening tool is opened on the grounding side.The interior of the insertion port is blind, and water, which causes rust, There is no entry into the counterbore (7) where the soil and sand nuts (2) are exposed.

The bottom member (3) has a counterbore (not shown) having a depth equal to or less than a wire diameter of the ring packing (6) and a diameter to which the spike seat plate (5) fits. 7) and a part of the nut (2) buried in the center of the bottom of the counterbore (7) slightly protrudes to form a groove around which the ring packing (6) fits.
