DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slipper for footwear such as golf shoes, a wrench for slipper for footwear for attaching and detaching the slipper for footwear to the bottom of the footwear, and a shoe wrench for such footwear. The present invention relates to a footwear slip set including a slipper and a footwear slipper wrench.

[0002]

2. Description of the Related Art Conventionally, spikes made of metal or ceramics have been used as non-slip devices for golf shoes. In addition, a non-slip device made of a synthetic resin is often used. Since the non-slip protruding portion of such a synthetic resin non-slip tool is more susceptible to abrasion than a metal non-slip component, a metal or synthetic resin male screw portion is provided on the back side of the non-slip component to protrude therefrom. By providing a female screw portion made of metal to be screwed on the bottom of the golf shoe, the non-slip device is configured to be removable.

[0003] In order to screw such a slipper into or out of the female screw portion of the shoe sole, the slipper is provided with a plurality of wrench insertion holes, and a plurality of special wrench insertion holes. The wrench had to be rotated with the rod inserted into the insertion hole of the slipper.

However, since the diameter of the slip stopper is, for example, about 10 to 20 mm, the cross-sectional area of the provided wrench insertion hole and the insertion rod portion inserted into the wrench insertion hole must be considerably reduced. Therefore, when it becomes difficult to release the screw due to long-term use, especially when removing the worn-out slipper, the insertion rod concentrates on the insertion rod to try to transmit a large rotational force to the wrench insertion hole. When a large stress is generated, the insertion thin rod portion and the insertion hole are deformed, and the insertion rod portion easily comes out of the insertion hole due to such deformation or the like, which may cause an injury to a user. In addition, the wrench insertion hole may be clogged with earth particles or gravel or the like, making it impossible to insert the insertion rod portion, and may not be able to release the screw engagement.

The present invention has been made in view of the above-mentioned problems in the prior art, and an object of the present invention is to provide a footwear slipper wrench with respect to a footwear slipper. A footwear slipper and a footwear slipper that can be stably rotated to efficiently transmit a rotational force, and that the screwing and unscrewing of the footwear slipper can be easily and surely and safely performed. A tool wrench and an anti-skid set for footwear.

[0006]

SUMMARY OF THE INVENTION (1) A footwear non-slip set according to the present invention is a footwear fixedly attached to the foot of a shoe to prevent the foot of the foot from slipping on the foot of the foot of the foot. A non-slip set for a footwear comprising a wrench for a non-slip tool for attaching and detaching the non-slip tool to the bottom of the footwear, wherein the non-slip component for the footwear is a bottom part of the footwear. A shaft part fixed in the axial direction and entirely or externally threaded, and a non-slip part which is located at the base end of the shaft part and is in contact with an object to be stepped on by the bottom of the footwear. The slip portion has a slip protrusion protruding in the axial direction toward the base, and one circumferential end of one of the slip protrusions and one of the slip protrusions The other one end in the circumferential direction of the portion is substantially opposite to the axial center line as one side affected portion. The other end in the circumferential direction of one of the non-slip protrusions and the other end of the other circumferential direction in any of the non-slip protrusions are located on the other side, respectively. As a pair of positions that are substantially symmetrical with respect to the axis, a portion of the non-slip portion on the one side in the circumferential direction of the one-side acted portion of the non-slip protruding portion of the axially proximal surface and A portion on the other side in the circumferential direction of the other side acted portion is a receiving surface portion inclined toward the center in the axial center direction, respectively.
The footwear slipper wrench is inclined outward toward the front in the direction of the fixed axis, substantially symmetrically on both sides of the fixed axis at a center angle of about 180 degrees with respect to the fixed axis. A pair of abutting end surfaces along the inclined line, having an operating surface portion on both sides of the abutting end surface portions on the rear side in the constant axial direction, and having an operating surface portion behind the operating surface portion in the constant axial direction, It has a grip portion for a user to grip and rotate around the fixed axis (claim 1).

[0007] A pair of receiving surface portions and a pair of receiving surface portions at one circumferential portion of the pair of one-side actuated portions at positions substantially symmetrical with respect to the axis in the slip portion of the footwear slipper. The pair of receiving surface portions of the other portion in the circumferential direction of the pair of other affected portions at positions substantially symmetric with respect to each other are located at positions substantially symmetric with respect to the axis.

[0008] A user of the footwear slipper wrench grips a gripper, and a pair of abutting end surfaces of the wrench for a footwear slipper wrench is slightly screwed into a female screw portion at the bottom of the footwear. The wrench for a footwear slipper is rotated in any direction around a fixed axis in a state in which the wrench for the footwear slipper is brought into contact with a pair of receiving surfaces at positions substantially symmetrical with respect to the axis of the slipper. Thereby, a pair of one-side affected portions or a pair of other-side affected portions adjacent to each receiving surface portion can be pushed around in the circumferential direction by the operating surface portion of the wrench for the footwear slipper wrench. Thereby, the shaft part of the footwear slipper can be screwed and fixed to the female screw portion, and similarly, by rotating the footwear slipper wrench in a reverse direction around a fixed axis, The threaded engagement of the shaft portion of the footwear slipper with the female screw portion can be released.

The pair of abutting end faces of the wrench for a footwear slipper are substantially symmetrical on both sides with a center angle of about 180 degrees with respect to a certain axis, and are directed outward in the direction of the certain axis. It is inclined. In addition, a pair of receiving surface portions with which the respective contact end surface portions abut are inclined in the axial direction toward the center. Therefore, as described above, the pair of abutting end surfaces of the wrench for footwear slippers are respectively brought into contact with the pair of receiving surfaces at positions substantially symmetrical with respect to the axis of the slipper portion of the footwear slipper. When the footwear slipper wrench is rotated about a certain axis in the contacted state, the pair of abutting end surfaces are displaced to any side in the radial direction with respect to the slip portion of the footwear slipper. It is difficult to rotate the position and the rotation axis of the wrench for footwear slippers with respect to the footwear slippers in a stable state,
The turning force can be efficiently transmitted from the wrench for the footwear slipper to the footwear slipper to perform the screwing and unscrewing of the shaft portion of the footwear slipper. Also, unlike the related art, there is no need to insert a plurality of wrench insertion rod portions of the wrench into a plurality of wrench insertion holes provided in the slip stopper, so that the screwing and unscrewing operations are easier. .

In addition, the transmission of rotational force from the wrench for the footwear slipper to the slipper for the footwear is performed by the action surface on the rear side of the contact end surface of the wrench for the footwear slipper in the direction of the fixed axis. This is performed on one end or the other end in the circumferential direction of the slip projection of the slip stopper. Therefore, as in the prior art, since the rotational force is transmitted by the insertion thin rod portion inserted into the plurality of wrench insertion holes provided in the slip stopper, the force is concentrated on the insertion thin rod portion and a large stress is generated. Unlike the thin rod part and the insertion hole that deformed and the insertion thin rod part easily slipped out of the insertion hole and could cause injury, the force concentrated on a part of the footwear slipper wrench and large Since no stress is generated, the working surface of the wrench for footwear slippers and the slip projections of the footwear slippers are not easily deformed, and the footwear slippers for screwing and unscrewing are used. The rotation force can be easily and reliably transmitted from the wrench to the footwear slipper, and also safely. Further, unlike the conventional case, the wrench insertion hole is not clogged with soil particles, gravel, or the like, so that the insertion thin rod portion cannot be inserted, and the screw engagement cannot be released. No wrench insertion hole is required.

Of course, it is highly convenient for work such as additional tightening and retightening after the footwear slip fastener is screwed and fixed. (1-1) The wrench for a footwear slipper of the present invention is substantially symmetrical on both sides separated by about a 180-degree central angle with respect to the fixed axis at the tip of the fixed axis direction, and is directed outward. The apparatus has a pair of abutting end faces along an inclined line inclined forward in the constant axial direction, and has a working surface section on both sides of the abutting end face sections on the rear side in the constant axial direction, and has a working surface section, A grip portion for gripping by the user and rotating about the fixed axis substantially behind the action surface portion in (2).

The shape of the wrench for the slipper for footwear does not necessarily have to be symmetrical with respect to the above-mentioned fixed axis. The material of the wrench for the footwear slipper is not particularly limited, but may be, for example, metal.

[0013] The pair of abutting end surfaces are substantially symmetrically formed on both sides of the fixed axis in the front end portion of the wrench for footwear slippers at a center angle of about 180 degrees with respect to the fixed axis. Along the inclined line inclined toward the front in the direction of the constant axis. The inclined line may be, for example, inclined in a concave curve backward in the direction of the fixed axis. Further, the pair of abutting end face portions may form a continuous surface.

[0014] A central portion between the two contact end portions may have a concave portion that is recessed rearward in the direction of the constant axis. When a central portion of the non-slip portion of the footwear slipper has a protrusion in the base axial direction that fits into the concave portion, the concave portion is fitted into the protruding portion to thereby provide the slipper for footwear. Can easily be aligned with the constant axis of the wrench for footwear slippers.

The dimension of each contact end face and the action face in the direction perpendicular to the fixed axis is, for example, one sixth to one half of the radial dimension of the slip portion of the footwear slipper. Preferably, it can be set to about 1/4 to 3/8. More specifically, for example, about 2 to 15 mm, preferably about 3 m
m to 10 mm.

[0016] It is expected that the gripping portion has a suitable position and shape for the user to grip and rotate the wrench for footwear slippers about a substantially fixed axis.
It does not need to be a specific shape.

[0017] The footwear slip wrench may be provided with a green fork behind the working surface in the constant axial direction.

In this case, the green fork and the grip may partially or entirely overlap.

Further, the wrench for the slipper for footwear can be flat as a whole (claim 4).

However, it is not always necessary to have a flat shape. For example, a part or the whole of the edge portion of the plate-shaped body may have a cross-sectional shape that protrudes to both sides in a substantially T-shape.

The portion of the wrench for footwear slipper having the contact end surface and the working surface, that is, the working end, is such that the receiving surface of the footwear slipper is sandwiched between the projections. In this case, the thickness must be such that it can be inserted between the projections.

It is desirable that the working end hardly protrudes outside the outer periphery of the slip portion of the footwear slipper. When rotating the footwear slipper wrench to screw and release the footwear slipper, to prevent the working end from being caught by other objects in the footwear bottom and hindering the work. is there. (1-2) The footwear slipper of the present invention is a footwear slipper fixedly attached to the bottom of the footwear in order to prevent the footwear from slipping on the object which the foot of the footwear touches. A shaft portion fixed in the axial direction and entirely or externally threaded, which is screwed and fixed to a female thread portion provided at the bottom of the footwear, and a bottom portion of the footwear which is located at the base end of the shaft portion and is to be stepped on A non-slip portion, wherein the non-slip portion has a non-slip protruding portion protruding toward the base in the axial direction. The other end in the circumferential direction of the non-slip protruding portion is located at a pair of positions substantially symmetrical with respect to the axis as the one-side affected portion, and the circumferential direction in any one of the non-slip protruding portions The other end and the other end in the other circumferential direction of any one of the anti-skid projections are respectively the other-side acted portions. A pair of positions substantially symmetrical with respect to the axis, and a portion of the non-slip portion on the one side in the circumferential direction of the one-side affected portion of the non-slip protruding portion of the axially proximal surface and the non-slip portion; The portion on the other side in the circumferential direction of the other-side operated portion is a receiving surface portion inclined toward the center in the axial direction toward the center.

The non-slip portion may be made of a relatively soft material as a whole or at least the non-slip projection. In this case, a lawn such as a green of a golf course and floors of various buildings are hardly damaged, and the comfort is good even on a hard road surface or a floor surface. As an example of the relatively soft material constituting the non-slip portion, a relatively soft synthetic resin such as a relatively soft nylon resin or a urethane resin can be given.
The non-slip portion can be formed, for example, in a substantially disk shape having a diameter of 10 to 30 mm.

Examples of the non-slip projection include small projections or small projections, projections or projections, three or more linearly arranged projections, or three or more spirally radially arranged projections. And the like.

The shaft may be made of a relatively hard material. As a result, it is possible to prevent the shaft portion from being torn due to an unexpected force acting during use, the male screw portion of the shaft portion being damaged by a screwing operation or the like, and the function being unable to function or the function being reduced is prevented. It is. As the relatively hard material forming the shaft portion, for example, a relatively hard metal material such as stainless steel, a fine ceramic material, a relatively hard nylon resin, a Duracon, and a relatively hard fiber reinforced as necessary. Of synthetic resin.

The axial direction of the footwear slipper is the axial direction of the shaft portion. The base in the axial direction is a direction in which the bottom of the footwear faces a stepping target such as the ground.

It is preferable that the one-side acted portion and the other-side acted portion of the non-slip protruding portion are end faces or edges which are as parallel as possible in the axial direction. The axial dimension of the one-side affected part and the other-side affected part can be, for example, 1 to 10 mm, and preferably 2 to 5 mm.

The non-slip protruding portion protrudes toward the base in the axial direction, and can be located at a portion near the outer periphery. In particular, a part or all of each one-side actuated part and each other-side actuated part can be located on the outer peripheral part of the non-slip part. In this case, the torque acting on the footwear slipper from the working surface of the footwear slipper wrench increases.

Further, in this shoe slipper, the one-side affected portion and the other-side affected portion may be located on both circumferential sides of the receiving surface portion.

In this case, when the footwear slipper is rotated in any direction, the contact end surface of the footwear slipper wrench may be brought into contact with the same receiving surface portion. High convenience.

Furthermore, this footwear slipper has a columnar body made of a relatively hard polymer material having a lateral projection on the base end side and a shaft end on the distal end side, and a side of the columnar body. A non-slip portion made of a relatively soft polymer material and enclosing the overhanging portion can be integrated.

Such a non-slip portion is formed by solidifying a relatively soft polymer material so as to cover, for example, a laterally extending portion of a columnar body made of a relatively hard polymer material manufactured in advance. Can be manufactured by In this case, for example, the side projecting portion may project sideways over the entire circumference (for example, in a disk shape or a polygonal shape), but it is ensured that the columnar body and the non-slip portion are integrated. In doing so, several directions (for example, 2
Direction, 3 directions, 4 directions, etc. It is preferable that a relatively soft polymer material that protrudes to the side is solidified and spreads between the side protruding portions. In the case of a projecting sideways in several directions, it is preferable to provide side projecting portions at equal center angles. Also, a through hole in the axial direction is provided in the side projection, and a relatively soft polymer material is spread over the through hole and solidified so as to secure the integrity of the columnar body and the non-slip portion. You can also. (2) The footwear slipper of the above (1) is a footwear slipper fixedly attached to the footwear bottom so that the foot of the footwear comes into contact with the stepped object and prevents the footwear from slipping on the target. A shaft portion made of a relatively hard polymer material screwed and fixed to a female screw portion provided at the bottom of the footwear, and a relatively soft portion located at the base end of the shaft portion and in contact with an object to be stepped on by the bottom of the footwear. A non-slip portion made of a polymer material is provided, and a fixed portion or the whole in the axial direction in the outer peripheral portion of the shaft portion is a male screw portion, and a part of the male screw portion has a valley having a cross-sectional area of another. It may be provided with a locking portion smaller than the portion.

Since the non-slip portion of the bottom of the footwear in contact with the object to be stepped on is made of a relatively soft polymer material, it greatly contributes to prevention of damage to the green of a golf course, the floor of a building, and the like, and improvement of comfort. Also, the shaft portion screwed and fixed to the female screw portion provided on the bottom of the footwear is made of a relatively hard polymer material (for example, hard nylon resin), and the whole is made of a relatively soft polymer material. Since the shaft part is torn by unexpected force during use, or the male screw part of the shaft part is damaged by screwing work, it can be prevented that the tightening function can not be exhibited or reduced. In addition, the weight is reduced as compared with the case where the shaft portion is made of a metal material. Usually, a large number of such slippers for footwear are used by being fixed to the sole of each footwear, so that the effect of weight reduction is great. Also, even if it falls down into the lawn from the bottom of the footwear and bites into the blade portion of the lawn mower, the risk of damaging the lawn mower or the like is low.

A part of the male screw part in the shaft part is provided with a locking part in which the cross-sectional area of the valley is smaller than that of the other part, and this locking part is used in a screwing operation when screwed and fixed. Since it is plastically deformed and comes into pressure contact with the female screw portion to exhibit a locking function, the locking effect can be generated while the screwing operation is performed relatively smoothly.

The shaft portion is made of a relatively hard polymer material (for example, a relatively hard synthetic resin such as a hard nylon resin).

The non-slip portion is formed of a relatively soft polymer material (for example, a relatively soft synthetic resin such as a soft nylon resin or a polyurethane resin) which is located at the base end of the shaft portion and in contact with an object to be stepped on by the bottom of the shoe. Or synthetic rubber). It is preferable that the non-slip portion has a non-slip protruding portion that protrudes in the direction of the axis of the shaft portion (the direction in which the bottom of the footwear faces the object to be stepped on).

It is desirable that the locking portion is provided on the base side of the male screw portion.

In this case, when the shaft portion is screwed and fixed to the female screw portion, the locking portion is screwed to the female screw portion and plastically deforms at a later stage of the screwing operation, and is pressed against the female screw portion to prevent loosening. Therefore, the screwing can be smoothly performed as a whole, and the loosening prevention function is prevented from being impaired due to excessive plastic deformation due to the screwing.

The length of the locking portion in the helical direction of the valley may be, for example, 2 to 45 degrees over a central angle. The central angle is preferably 5 to 20 degrees. The length of the locking portion is determined according to the difficulty of the screwing and the degree of the locking effect.

The locking portion may have, for example, one to four (preferably two to three) turns in the spiral of the valley. The locking part is
For example, one to six locations may be provided during one rotation of the spiral of the valley. Preferably, there are two or three places. These are determined as necessary, such as the difficulty of screwing and the degree of the locking effect.

The cross-sectional area of the valley can be made smaller than that of the other parts by filling the bottom of the valley with the same material as that of the shaft.

In this case, also in the locking portion, the male screw portion of the shaft portion can be more smoothly screwed into the female screw portion, and the locking function can be sufficiently exhibited, and the bottom of the normal male screw portion is filled. It is easy to manufacture.

The depth of filling the bottom of the valley can be, for example, 1/5 to 4/5, preferably 1/4 to 3/4 of the depth of the valley. The filling depth is determined according to the difficulty of screwing and the degree of the effect of preventing loosening, etc.,
Depends on the shape of the thread. The whole of the valley bottom side in the width direction of the valley can be buried or a part thereof.

Embodiments of the present invention will be described with reference to the drawings.

FIGS. 1 and 2 show a non-slip set for footwear for golf shoes as an example of an embodiment of the present invention (which can also be used for other athletic shoes and other footwear).

FIGS. 1A and 1B show a footwear slipper 10 and a columnar body 12, wherein FIG. 1A is a plan view of the footwear slipper 10, and FIG. FIG. 2C is a cross-sectional view, FIG. 2C is a plan view of the columnar body 12, and FIG.

FIGS. 2A and 2B show a footwear slip set including a footwear slipper wrench 30 and a footwear slipper 10, wherein FIG. 2A is a front view thereof, and FIG. It is a center longitudinal cross-sectional view of the wrench 30 for stoppers.

The footwear slip stopper 10 comprises a columnar body 12 made of a hard nylon resin and a slip part 14 made of a polyurethane resin (a relatively soft synthetic resin).

At the upper end of the columnar body 12, there is provided a laterally extending portion 12a which projects in a cross shape in the front, rear, left and right horizontal directions.

The side projection 12a is molded and solidified so as to be covered with a polyurethane resin (a relatively soft synthetic resin) to form the non-slip portion 14, whereby the side projection 12a is formed.
The slipper 14 is included from above and below and from the outer periphery to constitute the footwear slipper 10 in which the columnar body 12 and the slipper 14 are integrated. The polyurethane resin also spreads to the concave portion 12b opened at the center of the upper surface of the columnar body 12 and the through hole 12c formed in the side projection 12a, so that the integration of the columnar body 12 and the non-slip portion 14 is strengthened.

The portion of the column 12 protruding downward from the non-slip portion 14 is the shaft portion 16. The shaft 16 has a female screw hole (for example, made of stainless steel) provided in the bottom of the golf shoe.
A male screw portion 16a that is screwed into the inside so as to be fitted thereinto is provided on the outer peripheral portion over the entire length.

The male screw portion 16a is provided at the same position in the circumferential direction at each of two rotations from the base portion of the spiral of the valley portion 16a1 at a center angle of about 15 degrees and at the bottom half side.
Is formed integrally with the shaft 16 in a state where the depth of the shaft 16 is filled with the same material as the shaft 16 in the width direction of the valley 16a1.

The upper surface of the non-slip portion 14 (excluding the central projection 19 and non-slip projection 20 described later) gradually bulges upward toward the center. A central projection 19 is provided on the upper surface of the non-slip portion 14, and is disposed at equal intervals in the circumferential direction around the central projection 19, and has an arc shape having a center angle of about 50 degrees in plan view, with the central portion facing the center. It has four upwardly protruding non-slip projections 20 of a protruding shape.

In FIG. 1 (a), the circumferentially clockwise front end of each anti-slip projection 20 is a front affected portion 20a, and the clockwise rearward end is a rear affected portion 20b. is there.
The front-side affected portions 20a of the two non-slip projections 20 facing each other across the center of the non-slip portion 14, and the rear-side affected portions 20b of the two non-slip projections 20 opposite each other across the center are respectively axis-aligned. It is located at a pair of positions symmetric with respect to the cord.

The upper surface of the non-slip portion 14 (the surface on the proximal side in the axial center direction).
The portion between the front-side affected portion 20a of any of the non-slip projections 20 and the rear-side affected portion 20b of the non-slip protruding portion 20 located in the clockwise direction in the circumferential direction is all upward toward the center. It is a receiving surface part which is convexly inclined upward.

The slipper wrench 30 for footwear is made of a stainless steel flat plate and has a symmetrical shape with respect to a vertical center line (constant axis) in FIG. 2 (a).

At the lower end of the wrench 30 for footwear slippers, a pair of abutting end surfaces 32 which are inclined symmetrically to the left and right with respect to the center line and outward and concave upward are provided at the lower end. A concave portion 34 that is recessed upward is provided at a central portion between the two contact end surface portions 32. The front and rear portions on the upper side of the respective contact end surface portions 32 are the operation surface portions 36, and the contact end surface portion 32 and the operation surface portion 36 constitute an operation end portion 38.

The working end 38 is inserted into a portion between the front-side actuated portion 20a of the non-slip projection 20 and the rear-side actuated portion 20b of the non-slip protruding portion 20 which is located clockwise in the circumferential direction. The thickness to get.

Above the working end 38 is a grip 40 for the user to grip and rotate about a center line, and the upper half is a green fork 42.

The shaft 16 of the footwear slip stopper 10 is slightly screwed (in this example, clockwise rotation) into the female screw at the bottom of the golf shoe.
The user holds the grip 40 of the wrench 30 for footwear slippers, and the pair of contact end surfaces 32 of the wrench 30 with respect to the axis of the slipper 14 of the slipper 10 for footwear. In the state of being brought into contact with a pair of receiving surfaces at substantially symmetric positions,
By rotating the footwear slipper wrench 30 clockwise around the center line, the pair of front-side actuated portions 20a adjacent to the respective receiving surface portions is moved to the action surface portion 36 of the footwear slipper wrench 30. Can be pushed clockwise in the circumferential direction. Thereby, the shaft portion 16 of the footwear slip stopper 10 can be screwed and fixed to the female screw portion. Since all of the front-side affected portions 20a and the rear-side affected portions 20b are located on the outer peripheral portion of the slip portion 14, the footwear slipper wrench 3 is provided.
The torque acting on the slipper 10 for footwear from the zero action surface 36 increases. In addition, the working end 38 of the footwear slip wrench 30 hardly protrudes outside the outer periphery of the slip portion 14 of the footwear slip device 10, so that the footwear slip device wrench 30 is used. When rotating, the working end portion 38 is prevented from being caught by another object on the bottom of the golf shoe, and the work is prevented from being hindered.

Similarly, by turning the wrench for footwear slipper 30 around the center line in the opposite direction, the threaded engagement of the shaft 16 of the footwear slipper 10 with the female screw portion can be released. it can. Since the front affected portion 20a and the rear affected portion 20b are located on both sides in the circumferential direction of the receiving surface portion, the wrench 30 for the footwear slipper wrench 30 when the footwear slipper 10 is rotated in any direction. May be brought into contact with the same receiving surface portion. Further, operations such as additional tightening and retightening after the footwear slip stopper 10 is screwed and fixed can be similarly performed.

The pair of abutting end surfaces 32 of the footwear slip wrench 30 are inclined symmetrically to the left and right with respect to the center line, and are inclined downward and downward in the outward direction. Further, a pair of receiving surface portions with which the respective contact end surface portions 32 are in contact are inclined upward to protrude toward the center. For this reason, the pair of contact end surfaces 32 of the footwear slipper wrench 30 are respectively brought into contact with the pair of receiving surface portions of the slipper 14 of the footwear slipper 10 at positions substantially symmetric with respect to the axis. When the footwear slipper wrench 30 is rotated around the center line in the contacted state, the pair of contact end face portions 32 with respect to the slip portion 14 of the footwear slipper 10 can be any radial direction. The wrench 30 for footwear can be rotated in a state in which the position and the rotation axis of the wrench 30 for footwear are relatively stable with respect to the slipper 10 for footwear. The rotational force can be efficiently transmitted to the tool 10, and the screwing and unscrewing of the shaft 16 of the footwear slip stopper 10 can be performed.

The transmission of the rotational force from the footwear slipper wrench 30 to the footwear slipper 10 is carried out by the working surface 36 of the footwear slipper wrench 30. This is performed on the front-side affected portion 20a or the rear-side affected portion 20b of the portion 20. For this reason, since the force is not concentrated on a part of the footwear slip wrench 30 and a large stress is generated, the working surface portion 36 of the footwear slip wrench 30 is not generated.
And the slippery protrusion 20 of the footwear slipper 10 is hardly deformed, and the transmission of the rotational force from the footwear slipper wrench 30 to the footwear slipper 10 for screwing and unscrewing is easy and easy. It can be performed securely and safely.

As described above, in the slipper for footwear 10 attached to the sole of a golf shoe, the slip portion 14 in contact with an object to be stepped on by the bottom of the footwear is made of polyurethane resin which is a relatively soft synthetic resin. It greatly contributes to the prevention of damage to greens and floors of buildings and to the improvement of comfort.
Further, since the shaft portion 16 screwed and fixed to the female screw portion provided on the bottom of the golf shoe is made of a hard nylon resin, an unexpected force acts during use, and the shaft portion 16 is torn or screwed. This prevents the external thread portion 16a of the shaft portion 16 from being damaged and not being able to exhibit the tightening function, or preventing the male screw portion 16a from deteriorating, and is reduced in weight as compared with the case where the shaft portion 16 is made of a metal material.

Further, since the locking portion 18 is provided on the shaft portion 16 at the base side of the male screw portion 16a, the shaft portion 1 is provided.
When the screw 6 is screwed and fixed to the female screw portion, the locking portion 18 is screwed to the female screw portion and plastically deformed in the latter half of the screwing operation, and is pressed against the female screw portion to exhibit the locking function. for that reason,
The screwing can be performed more smoothly as a whole, and the plastic deformation due to the screwing is prevented from progressing excessively, thereby preventing the loosening prevention function from being impaired. In addition, since the bottom of the valley portion 16a1 is filled with the same material as the shaft portion 16, the male thread portion 16a of the shaft portion 16 can be more smoothly threadedly engaged with the female thread portion. In addition, since the function of preventing loosening can be sufficiently exerted and the bottom of the normal male screw portion 16a is filled with the same material, the manufacture is easy.

Note that the vertical positional relationship in the description of the above embodiment is for convenience of description based on the drawings, and does not limit the actual use state and the like.
