Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a sole for golf shoes.

(Prior Art) Conventionally, golf shoe soles having a large number of anti-slip protrusions integrally formed with the rubber sole body 1 on the ground contact surface are generally well known.

Although such soles are convenient because they do not require changing shoes on golf courses, clubhouses, on the streets, etc., they have insufficient grip on the ground during play, particularly during swings, and have problems with swing stability. For this reason, athletic shoe soles with non-slip protrusions made of hard synthetic resin have been proposed in Japanese Patent Publication No. 54-40980, but these soles have problems with walkability on floors and streets. Ta.

(Problems to be Solved by the Invention) This invention solves the problem in that the bottom of the fifth middle phalanx of the sole (a), the bottom of the fifth proximal phalanx (b), the fifth
An almost straight line connecting the tip of the body of the metatarsal bone (c) and the rear end (d), the anterior lateral side of the calcaneus (e), -1 2- the rear part of the calcaneus (f), and the sole of the foot. A substantially straight line M connecting the bottom of the third middle phalanx (g), the middle part between the center of the second and third metatarsal bodies (h), and the medial side of the talus (i). The left and right feet are simultaneously tilted in the medial-lateral direction and the medial-lateral direction, respectively, and these two axes land on the ground respectively during the swing, and the maximum weight pressure is transferred along these axes. By focusing on this and improving the grip of the sole, we aim to provide a sole for golf shoes that provides stability during swings and excellent walkability on the floor and on the road. be.

(Means for Solving the Problems) The present invention will be described below with reference to the drawings. In the present invention, a large number of anti-slip protrusions 11, 11... are formed integrally with the rubber sole body 1 on the ground contact surface.

A nearly straight line connecting the position (a) corresponding to the bottom of the fifth middle phalanx of the sole and the position (b) corresponding to the rear medial side of the calcaneus of the sole, and the third middle phalanx of the sole - At the center of a large number of protrusions 11', 11'... arranged on a substantially straight line M connecting the position corresponding to the bottom of the bone (c) and the position corresponding to the medial side of the talus of the shoe sole (d), respectively. , J.I.
Hardness according to SK6301 spring type hardness test A type is 8
5 to 95 hard rubber studs 2.2... to their tips 21.
21... are sprayed out at the same height or slightly lower than the tips 111', 1.11'... of the protrusions, and the bases 22, 22... are embedded and attached in the sole body 1. The gist of the invention is a sole for golf shoes characterized by the following.

In this invention, the sole body] is made of a solid material or a foam material such as ordinary rubber or urethane rubber, and its hardness (hardness according to JIS K6301 spring type hardness test type A - hereinafter simply referred to as hardness) is 65. It is preferable to set the hardness to ~75, because if the hardness is lower than that, the compressive deformability of the protrusions 1111 formed integrally with the sole body 1 will become too large, resulting in poor landing stability when walking on the road. 4- Also, if the hardness is higher than that, the compressive deformability of the protrusions 11, 11... will be too small, reducing the impact cushioning properties when walking on the road, and making it uncomfortable to wear. There is.

The protrusion 11.11... has a polygonal columnar shape, a polygonal truncated pyramid shape, a cylindrical shape,
Although it may be formed in any suitable shape such as a truncated cone shape, it is convenient to form it in a truncated cone shape or a cylindrical shape so that it will not damage the lawn on a golf course. From the viewpoint of grip to the ground and damage to the lawn during swing, when the protrusions 11.1.1 are formed into a truncated conical or cylindrical shape, the diameter at the ground contact surface should be 4.0 to 9. O
m+, the protrusion height from the sole body 1 is 4, 0 to 8
, 0 + nm, and the interval between the centers 112, 112-... is preferably set to 0.7 to 20 m+.

If the diameter and height are less than that, but the distance is more than that,
The damage to the grass will be reduced, but the grip on the ground will be poor, and the stability when swinging will be reduced.If the diameter and height are larger than that, but the spacing is less than that, the stability when swinging will be poor. However, it tends to cause more damage to the lawn.

In this invention, on a substantially straight line, when worn in a shoe, the bottom of the fifth middle phalanx of the foot (a), the bottom of the fifth proximal phalanx (b), and the tip of the body of the fifth metatarsal. (Q), the rear end (d), the anterior lateral side of the calcaneus (e), and the posterior part of the calcaneus (f) are approximately located, and on the straight line M is the third part of the foot when worn inside the shoe. The bottom of the middle phalanx (g), the middle part between the center of the second and third metatarsal bodies (h), and the medial side of the talus (i)
When the shoes are swung, the left and right soles are tilted outwards about the straight line, and inwardly about the straight line M. And the straight sole of the shoe, M
The protrusions 11', 11'... arranged on the top are formed in a cylindrical shape from the viewpoint of grip on the ground during swing, and a rubber stud 2 is placed in the center of the cylindrical protrusions 11', 11'... .2... is its tip 21, and 21... is the tip 11], ', 111'... of the cylindrical protrusion, which is approximately the same height 6-.
6- If exposed slightly lower than that, when weight pressure is applied to protrusions 11', 11'... during swing,
The protrusions 11', 11'... are easily compressed and deformed, and the tips 21, 21... of the rubber studs 2゜2... exposed at their centers are projected onto the ground (grass surface) and pressed into contact with the grass. For,
The grip on the ground is further improved, and when walking on the floor or the road, cushioning properties are imparted by compressive deformation of the cylindrical protrusions 11'', 11', etc., resulting in even better walking performance.

In this invention, the protrusions 11', 11'... are straight.

They may be arranged at regular intervals on M, or they may be arranged concentrated on the parts of the sole where the maximum pressure is applied during swing, such as the toe, treading part, and heel part. Good too.

In this invention, the hardness of the rubber studs 2.2... attached to the protrusions 11', 11'... is limited to 85-95, because if the hardness is less than that, the rubber studs 2.2...
The compressive deformability of the material becomes too large and the grip on the ground decreases.

7- If the swing stability of the sole decreases and the hardness exceeds that level, it will easily damage the floor, road surface, grass, etc., and when used on hard surfaces such as asphalt, concrete, tiles, etc. This is because when landing, the upward pressure from the ground against the sole of the foot increases through the rubber studs 2, 2, etc., resulting in a disadvantage that the feeling of wearing such as walking and running performance deteriorates.

In this invention, the rubber studs 2.2... may be formed independently, but a plurality of rubber studs 2.2... having a φ truncated conical shape are connected in series via the plate portion 20. When molding the sole body, set it in the mold by fitting the tip of the stud into the holding hole formed on the bottom of the mold, and place the sole body molding material in the mold cavity. This is then heated and pressurized to form the sole body 1.
When molded, the plate portion 20 is embedded in the sole body 1 along with the base portions 21, 21 of the studs,
It is possible to set a large number of studs 2, 2... in the mold cavity at the same time, and when molding the sole body 1, studs 2.
．． 2... does not move and is convenient to mold, and the shoe sole formed in this way has a plurality of rubber studs 2. Since the plate part 20 is embedded in the sole body 1 along with the rubber studs 2.2...
It can significantly increase the burial strength against
The upward pressure from the ground applied to any of the rubber studs 2, 2, .

Furthermore, in the present invention, the anti-slip protrusion is located at a position (e) corresponding to the head (j) of the first proximal phalanx of the shoe sole, which is subjected to the maximum stepping pressure during swing, or at a position adjacent thereto. 11'', protrusions 11', 11'...same rubber studs 2
．． By additionally attaching 2..., it is possible to further improve the grip on the ground during the swing special and further improve the stability during swing.

(Operations and Effects of the Invention) As described above, in this invention, since the anti-slip protrusions 11, 11... are formed integrally with the rubber sole body 1, the floor surface,
The shoes are comfortable to wear when walking on the road, and do not damage the floor or road. Also, when the left and right shoe soles are simultaneously tilted in the medial-lateral direction and the medial-lateral direction during swing, the protrusions 11', 11'... arranged on the straight M (inclination axis) move the maximum weight pressure. The tips of the hard rubber studs 21, 21, which are compressed and buried in the center, are pressed against the grass and bite into the grass, providing good grip on the ground and providing stability during swing. In good condition. Also, since the studs 2, 2... are made of rubber, they will not damage the lawn.
