BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to improvement of the sole of an athletic shoe suitable for bowling.

[0002]

2. Description of the Related Art In bowling, the body is supported by the foot opposite to the hand throwing the bowl and the foot is slid during pitching. This slip has a great influence on the score and also depends on the habits and physical condition of the person, the state of the approach of the bowling alley, for example, the lane of the bowling alley makes it slippery or less slippery, and also depends on the environment (temperature, humidity, etc.). Therefore, one type of shoe (specific shoe sole) cannot sufficiently meet the above conditions.

Therefore, each athlete (wearer) attaches a sheet of polytetrafluoroethylene resin (trade name: Teflon) to the ground contact surface of the shoe sole in order to improve his / her preferred slipping. Had been improved. However, this not only takes a lot of time for the sticking work, but also has an adverse effect such as dust adhering to the sheet even after peeling.
Further, in order to improve this, there is also one in which recesses are provided in a part of a part of the ground contact surface of the shoe sole so that it can be replaced with some materials having different slips. However, this is not enough to solve the above problems.

[0004]

SUMMARY OF THE INVENTION In order to overcome the above-mentioned defects of the sole of the conventional bowling shoes, the present invention is directed to the conditions of the lane of the bowling alley, room temperature and humidity, and the physical condition of the athlete (wearer). The solution is to remove and replace the parts on the grounding surface side, which have different dynamic friction coefficients and have a large sliding effect on part or all of the grounding surface of the shoe sole depending on the habit or the like.

[0005]

SUMMARY OF THE INVENTION In the present invention, a base portion a to which a velvet fastener engaging element 4 is attached and a bottom surface b are formed on the lower surface side and a velvet fastener engaging element 5 is attached to the upper surface side. Toe part 1 and heel part 3 and both parts 1 and 3
It is made up of a central part 2 except for the above, and it is novel to removably connect the engaging part 5 of the toe part 1, the engaging part 5 of the central part 2 and the engaging part 5 of the heel part 3 to the engaging part 4 of the base portion a. Use it as a means.

[0006]

In the shoe sole A of the bowling shoe of the present invention, the toe part 1 forming the ground contact surface bottom b, the engaging portion 5 having the central portion 2 and the heel portion attached to the upper surface side thereof, the lower surface side of the base portion a. It is detachably coupled to the engaging element 4 attached to the. Further, the toe portion 1, the central portion 2 and the heel portion forming the ground contact surface bottom b have dynamic friction coefficients of 0.2 to 0.8 and 0.2, respectively.
Prepare a plurality of ones in the range of 0.7 to 0.3 and 1.2 to 1.2, and select the desired one in accordance with the conditions of the bowling alley lane, room temperature, humidity, and the like.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A shoe sole A for bowling according to the present invention comprises a toe part 1, a center part 2 and a heel part 3 which form a ground contact surface bottom b.
The sliding condition and pressure distribution of about 12 professional bows,
After studying the load conditions, etc., a person who controls the slip by applying a load to the toe part, a person who controls the slip by applying a load to the center part, or a load from the heel part controls the slip There are people who do this, and if there is a portion with a large dynamic friction coefficient where a large load is applied, resistance will increase and it will be difficult to slip, so use parts with an appropriate dynamic friction coefficient according to the size of the applied load. I was careful. That is, as shown in FIGS. 1 and 2, the bowling shoe sole A of the present invention is composed of a base portion a and a ground contact surface bottom b, and the base portion a is shown in FIGS. As described above, the engaging element 4 such as a so-called velvet fastener (product name: Velcro tape, etc.) is attached to the lower surface side. Similarly, the ground contact surface bottom b is divided into a toe part 1, a center part 2 and a heel part 3, etc., as shown in FIGS.
The parts 1, 2 and 3 of the ground surface bottom b are joined to the base a by the engagement elements 5 engaging the engagement elements 4 of the base a on the respective upper surfaces. Further, each part of the ground contact surface bottom b may be any so long as it is the sole of a well-known bowling shoe, for example, artificial leather such as (Exeine: trade name), synthetic leather, cowhide, natural leather such as deerskin, synthetic resin or Examples thereof include solid bodies such as natural or synthetic rubber and foams.
Further, specifically, resin-coated nap-like artificial leather or nap-like artificial leather is selected for the toe component 1, and deer leather velor or cowhide velor is selected for the heel component 3. Further, the dynamic friction coefficient of each of the components 1, 2 and 3 forming the ground contact surface bottom b is the dynamic friction coefficient by the test performed by the surface quality measuring device HEIDON-14DR of Shinto Scientific Co., Ltd., and the test conditions at that time are as follows. Floor material: Resin coated plywood Speed: 1050 mm / min Load: 1000 g Moving distance: 35 mm Test piece: 60 × 60 mm, toe part 1 having a dynamic friction coefficient in the range of 0.2 to 0.8, central part 2 dynamic friction The coefficient is in the range of 0.2 to 0.7, and the heel part 3 has a dynamic friction coefficient of 0.3 to 1.2.
Is.

Materials having a standard coefficient of dynamic friction for each part 1, 2 and 3 of the ground contact surface sole b of the shoe sole A are as follows:
For example, the toe part 1 is napped artificial leather having a dynamic friction coefficient of 0.33, and the central part 2 is resin coated napped artificial leather having a dynamic friction coefficient of 0.28.
The heel component 3 may be a combination of deer velours having a dynamic friction coefficient of 0.37. The base a is the bottom of the ground plane b.
As in the case of each of the parts 1, 2 and 3, etc., a conventional shoe sole member such as artificial leather, synthetic leather, natural leather and a mixture of two or more sets of any of synthetic or natural rubber or synthetic resin or a solid body of these or Either of the bubbles may be used.

Further, each portion 1, 2 and 3 of the ground contact surface bottom b
May have any shape, but includes, for example, a heel portion having a normal width as in the embodiment shown in FIG. 6, or the heel part 3 of the heel portion 3 as in the embodiment shown in FIG. A part of the part is extended toward the central part 2, and further, as shown in FIG. 8, a recess b is formed in the arch part where the load of part of the central part 2 is hardly applied. You can also suggest things.

In the sole A of the bowling shoe of the present invention, the parts 1 and 2 and 3 of the ground contact surface bottom b can be used by combining the desired parts 1 and 3 within their respective dynamic friction coefficients. The engagement elements 4 and 5 can be detachably used for exchange.

[0011]

The sole A of the bowling shoe according to the present invention is formed so that each component forming the ground contact surface bottom b, that is, the toe component 1, the central portion 2 and the heel portion 3 are easily and detachably connected from the base portion a. Therefore, even if any one of the parts 1, 2 and 3 is worn, the same one can be prepared and replaced, so that it is not necessary to replace the shoe or the sole A, which is economical. Similarly, each part 1, 2 and 3 should have a specified coefficient of dynamic friction so that it can be adapted to the wearer's (player) 's own habits, physical condition, bowling room temperature and humidity, lane conditions (hardness and applied oil), etc. Any combination can be used so that the shoe wearer can play under his own conditions and get the highest score.
