Abstract

PROBLEM TO BE SOLVED: To provide the mounting structure of the spike fitting of a baseball shoe, which is easy to change the rising angle θ of each of spike nails 22 and heightens tightening force to an outsole 11.SOLUTION: The spike fitting 20 consists of a regular polygon board 21 applied to the under surface of the outsole and one spike nail 22 which rises from the surface of the board. If one spike nail is separately attached to the outsole by the board, the attaching position and rising angle θ of each spike nail can be arbitrarily obtained. Thus, the spike nails can be installed in the best position which fully corresponds to the difference of a defense position, the peculiarity of a player, etc. The spike fitting is firmly attached to the outsole by the bite of an acute projection 24 and the insertion of the board to the frame 40 of the outsole. Since the spike nails 22 rise from the linear part (side) 21a of the board, by one piece, the spike fitting can be obtained by raising the spike nails from the board by bending processing.

Description

  The present invention relates to a spike fitting mounting structure in which a spike fitting is attached to the bottom (bottom surface) of an outsole of a baseball shoe.

In baseball shoes, spike metal fittings are provided on the lower surface of the outsole (sole) to secure the tension during running, bat swing, ball throwing, and the like. The spike fittings are mainly made of metal, but there are also plastics.
The base metal shoe spike fitting is generally composed of a substrate fixed to the lower surface of the outsole and a spike claw rising from the surface of the substrate (see Patent Document 1). Further, in the case where the spike claw is made of metal, it is generally a single piece that is bent and raised from the peripheral edge of the substrate, and is generally an outsole for the nail (screw), rivet, etc. By fixing to, the spike fitting is attached to the lower surface of the outsole.

In the baseball shoe spike fitting, conventionally, a plurality of spike claws are provided on a single board, and the spike fitting is based on the change of the mounting position of the board, and the position of the spike claw and the tip direction. (See FIG. 2 in this application, the angle β in the width direction of the spike claw 22 with respect to the left-right direction) can only be changed (see Patent Document 1 FIGS. 1 to 3). That is, it is not possible to change the position of each spike claw, change the rising angle β with respect to the toe direction, or change the rising angle (see angle θ in FIG. 3). .
For baseball players, the best position of spike claws, the best rise angle β with respect to the toe direction, and the best rise angle θ vary depending on the difference in the defensive positions of pitchers, infielders, outfielders, etc. is there.

  On the other hand, there is a spike metal fitting in which one spike claw is provided on a substrate and the substrate is fitted into a frame on the lower surface of the outsole having the same inner peripheral surface shape. In these spike fittings, there is one in which the rising angle β with respect to the tip direction of the spike claw can be changed by fixing the substrate at the required rotational position within the frame (Patent Document 2). There is also one that is a strong fixing means for spike fittings (Patent Document 3).

Japanese Utility Model Publication No. 60-25408 Japanese Utility Model Publication No. 60-146403 Japanese Utility Model Publication No. 60-4206

  By fixing the substrate at the required rotational position within the frame, the rising angle β with respect to the tip direction of the spike claw can be changed (Patent Document 2). Although it has a triangular gear shape and the adjustment ratio of the angle β has a fine advantage, if each tooth shape is not accurate, a gap is generated between the peripheral edge of the substrate and the inner peripheral surface of the frame, and the earth is in the gap. Intrusion of the soil tends to cause troubles such as deterioration of the mounting strength of the spike fitting. In addition, the spike claw is fixed to the substrate by brazing (see FIG. 7 of the same document 2), and there is a problem in its fixing strength.

  Furthermore, although the idea of bending and raising the spike claw from the substrate is also shown (see Patent Document 2 FIGS. 8 to 11), in this spike metal fitting, the rising outer surface of the spike claw, the inner peripheral surface of the frame, A large gap is formed between the two, and the soil that enters the gap causes problems such as deterioration of the mounting strength of the spike fitting. Similarly, there is also shown the idea that the spike claw is bent and raised from the substrate and the substrate is resin-coated in a shape corresponding to the inner peripheral surface of the frame (see Patent Document 2 FIGS. 12 to 17). There is a problem that the metal fitting becomes heavy as much as the resin coating.

  In addition, what used the frame as the strong fixing means of the spike fitting (Patent Document 3) has a substantially rectangular frame (see the same document specification, page 3, lines 15 to 16). There is no idea that the rising angle β of the spike claw with respect to the tip of the spike can be changed because there is a frame in which the frame is a strong fixing means of the spike fitting.

  Under the above circumstances, an object of the present invention is to facilitate the formation of spike claws and to easily change the rise angle and the like of each (individual) spike claws.

In order to achieve the above-mentioned object, one means of the present invention is that a spike fitting comprises a regular polygonal substrate in plan view and a single spike claw that rises from at least one side of the substrate by bending. It was.
In this way, if one spike claw can be attached to the outsole with the substrate, the attachment position of the spike claw, the rising angle β with respect to the toe direction, and the rising angle θ can be obtained arbitrarily. The spike claw can be provided with the best position, the rising angle and the like sufficiently corresponding to the difference in the defensive position and the player's heel.
In addition, since the substrate is polygonal in plan view and spike claws are raised from at least one side of the substrate, the spike fitting can be manufactured by punching and bending from a single piece of metal. In addition to being inexpensive, since the bending process is performed, the fixing strength of the spike claw to the substrate is also high.

Next, according to the present invention, a frame surrounding the periphery of the substrate applied to the lower surface of the outsole is formed, and the inner peripheral surface of the frame is a regular polygon in a plan view same as the substrate.
According to this configuration, before the substrate (spike claw) is fastened to the outsole, the substrate is arbitrarily rotated at each vertex angle of the regular polygon in plan view, so that a plurality of directions with respect to the toe direction can be obtained. The rising angle β can be easily obtained.
In addition, since it fits within the frame, the fixing strength of the spike fitting to the outsole is sufficient, and since the substrate periphery and the frame inner peripheral surface are the same regular polygon in plan view, the substrate periphery and the frame inner periphery It is difficult to create a gap with the surface, and it is difficult for dirt to enter the gap.

  As a configuration of the present invention, the spike fitting mounting structure of the baseball shoe provided with a spike fitting on the lower surface of the outsole, the spike fitting is a planar regular polygonal substrate applied to the lower surface of the outsole, It consists of a single spike claw that rises from at least one side of the substrate by bending, and forms a frame surrounding the periphery of the substrate applied to the lower surface of the outsole. It is polygonal, and the board is fitted in the frame and fastened to the outsole with screws, nails or rivets passed through the holes in the board. It is possible to adopt a configuration in which the angle of the spike claw with respect to the toe direction can be adjusted by rotating the substrate.

Another means of the present invention for achieving the above-described object is that, similarly to the above-described means, the spike fitting is a polygonal substrate in plan view and a single spike claw that stands up by bending from at least one side of the substrate. It consisted of
The significance of this configuration is the same as above, but in this means, the substrate does not have to be a “planar regular polygon”, but is a “planar polygon”. This is because it cannot fit into the frame.

Next, according to the present invention, the substrate is provided with a sharp protrusion that bites into the lower surface of the outsole.
By doing so, the sharp projections bite into the lower surface of the outsole, and the spike fitting is firmly positioned on the outsole, and the positioning is ensured regardless of the position of the substrate and the direction of the spike claw. For this reason, the spike metal fitting is firmly positioned and fixed to the outsole at an arbitrary attachment position and rising angle of the spike claw.
At this time, even if there is no frame, the corners of the polygonal substrate bite into the outsole, so that the effect of increasing the fixing strength of the substrate to the outsole can be obtained.

  As a configuration of this invention, it is a mounting structure of a spike fitting of a baseball shoe provided with a spike fitting on the lower surface of the outsole, the substrate has a sharp protrusion that bites into the lower surface of the outsole, A board having a polygonal shape in plan view applied to the lower surface of the outsole and a single spike claw that rises by bending from at least one side of the board, and a screw, nail or In addition to fastening with rivets, the sharp protrusions bite into the lower surface of the outsole to make the substrate unrotatable.Before the fastening, the angle of the spike claw with respect to the tip of the spike claw is set by rotating the substrate around the hole. A configuration that can be adjusted can be employed.

  In both the above inventions, since the substrate has a polygonal shape in plan view, spike claws can be raised individually by bending each side thereof. That is, a spike claw that rises at a required angle α can be easily obtained (see FIG. 5 of the present application). At this time, if the spike claw is provided on at least one side of the substrate, the function of the spike is exhibited, but if provided on a plurality of sides, the spike force is increased. Furthermore, if it is continuous on each side, the substrate is a regular polygon in plan view, so that the catching force of the spike claw does not change at any rising angle β.

In each of the above inventions, if the rising angle of the spike claw located at the buttocks is 72 to 75 degrees, which is a backward warp with respect to the board, when the player slides into the baseball baseball, the player usually puts the baseball shoe on the ground. On the other hand, since it slides with an inclination of about 15 degrees (15 to 18 degrees), the spike claw bites into the ground at a substantially right angle. A right-angled bite can provide a stable braking effect.
Setting the rising angle θ of the spike claw to 72 to 75 degrees with respect to the substrate is set to 72 to 75 degrees of back warping or forward bending not only in the buttocks but also in all spike claws such as the toe portion. be able to. For example, if the rising angle θ of the spike claw at the toe part is 72 to 75 degrees that is bent forward with respect to the substrate, the toe part tilts backward and upward when traveling, so that the spike claw is substantially perpendicular to the ground. It will become a bite. A right-angled bite can provide a stable grip effect. The rising angle of 72 to 75 degrees can be employed only for the spike claw at the toe portion.

  S45C, S50C, S55C, S60C, and S65C that are the same as conventional materials can be used as the material (steel piece) of the spike fitting, but it is intended to further balance the wear resistance of the spike claw and the bending strength of the substrate. Can be SCM415, SCM420, SUS420, SUS420, or SUS440 that are not used as conventional spike fittings. Incidentally, Young's modulus (GPa) of S45C, S50C, and S55C is 206, Young's modulus of SCM415 and SCM420 is 210, Young's modulus of SUS420 and SUS440 is 204.

  When the substrate is fastened to the outsole with a screw, it is preferable to form a protrusion on the entire periphery of the hole of the substrate by burring or the like. In this way, the fastening washer can be substituted by the protrusion, and loosening of the screw after fastening can be prevented. For this reason, sufficient fastening of the spike fitting can be obtained for many years. As long as the ridge is an aspect that exerts the function of a washer on the entire circumference of the hole periphery, for example, any of the protrusions may be used.

Since the present invention is configured as described above and each spike claw can be attached at a required position and rising angle on the bottom surface of the outsole, it is best to sufficiently cope with differences in defensive positions, player's wrinkles, etc. It is possible to easily obtain a baseball shoe having a spike claw having a required rising angle at a position.
In addition, spike fittings can be manufactured at low cost, and the fixing strength of the spike claws to the substrate is high, and the fixing strength of the spike fitting to the outsole is sufficient. It is difficult for the gaps to occur, and it is difficult for soil to enter the gaps.

1 to 4 show an embodiment of a baseball shoe according to the present invention. In the baseball shoe of this embodiment, the shoe body 10 has an outsole 11 constituting a shoe sole, and an upper surface of the outsole 11. The inner member 12 is provided, and the upper 13 has a lower edge fixed to the entire peripheral edge of the outsole 11. Although not shown, an insole is appropriately provided on the intermediate member 12.
A spike fitting 20 is attached to an appropriate position on the lower surface of the outsole 11.

  This spike fitting 20 uses steel pieces such as S45C, S50C, S55C, SUS420, SUS440, SCM415, SCM420, etc., for example, 1.2 mm thick quenching made by Sumitomo Metal Industries, Ltd. It is manufactured by punching, bending and drawing steel pieces. At this time, it is preferable to increase the rigidity and elasticity of the spike fitting 20 by performing an austempering process, a shot peening process, a carbonitriding and quenching process, etc. according to the use environment, for example, for an outfielder.

  Incidentally, the thickness of steel pieces supplied and used (manufactured and sold) by the above-mentioned materials for spike fittings is 1.4 mm and 1.6 mm today. 0.0mm and 1.2mm are also manufactured and sold. In this embodiment, a steel piece with a thickness of 1.2mm is used in order to provide a higher elastic function than conventional spike fittings, and manufacturing tolerances Is ± 0.1 mm, the preferable thickness of the spike fitting (substrate) is 1.1 mm to 1.3 mm. At this time, even if it is a steel piece having a thickness of 1.4 mm, if it is a thin steel piece, in the case of a thickness of 1.3 mm, the thin steel piece having a thickness of 1.4 mm is also included. . Moreover, even if it is a steel piece of thickness: 1.0 mm, if it is a thickened steel piece, when the thickness is 1.1 mm, the steel piece of thickness: 1.0 mm is also included.

The spike fitting 20 includes a substrate 21 applied to the lower surface of the outsole 11 and a single spike claw 22 rising from the surface of the substrate 21. As shown in FIG. 4, the substrate 21 has a regular pentagonal shape in plan view, and a quadrangular spike claw 22 is formed by bending from a straight side 21 a at the periphery of the pentagon.
The rising angle θ of the spike claw 22 is generally a right angle (90 degrees) with respect to the substrate 21 as shown in FIG. 3 (a). θ is set to 72 to 75 degrees of back warping (see FIG. 5C).

  A hole 23 is formed in the center of the substrate 21, and a sharp protrusion 24 is provided on a surface of the substrate 21 that is applied to the lower surface of the outsole 11. The position and number of the protrusions 24 are appropriately determined in consideration of the biting strength. On the spike claw 22 side around the hole 23, a ridge 25 is formed on the entire circumference by burring. As shown in FIG. 3, when the spike fitting 20 is fastened with the screw 30, the protrusion 25 substitutes for a fastening washer by the protrusion 25 to prevent loosening of the screw 30 after fastening. .

A through hole 15 is formed at the attachment position of the spike fitting 20 of the outsole 11, and the cylindrical fitting 16 is fitted into the hole 15. The mounting bracket 16 has a sharp protrusion 18 on the end flange 17 of the end. The protrusion 18 bites into the outsole 11 (inner material 12), and the mounting bracket 16 is firmly fixed to the outsole 11.
The outer peripheral surface of the cylindrical body portion of the mounting bracket 16 is provided with uneven processing 16a. The unevenness 16a can bite into the inner surface of the hole 15 to obtain a high insertion strength into the hole 15. In addition, the surface of the substrate 21 and the spike claw 22 that is in contact with the ground (the ground surface) can be subjected to uneven processing to suppress the adhesion of soil.

As shown in FIG. 3 (a), the spike fitting 20 includes a screw (fitting through the hole 23 of the substrate 21 after fitting the fitting 16 into the hole 15 of the outsole 11 and biting the projection 18. Screws 30 are screwed into the mounting bracket 16 to fasten the spike bracket 20 to the lower surface of the outsole 11. The protrusion 18 and the protrusion 24 can be omitted as long as no troubles such as loosening of the spike fitting 20 occur.
As shown in FIG. 3B, instead of the screw 30, fastening with a rivet 31 can be used, and as shown in FIG. 3C, conventionally known nail fastening (fastening) 32 can be used. FIG. 3C shows a case where the rising angle θ of the spike claw 22 is backward warp or forward bending 72 to 75 degrees.

  As a form of the spike claw 22, not only a simple “square piece” shown in FIG. 4 but also a triangle piece, a pentagon piece, and the like are conceivable, and an aspect in which the square pieces are connected at a predetermined angle, for example, FIG. As in FIG. 5, it may be composed of two square pieces. In the case of the plurality of quadrangular pieces, if the substrate 21 is a polygon, preferably a regular polygon, each spike claw 22 can be raised from the straight sides 21a by bending.

  At this time, if there are two or more linear portions (sides) 21a adjacent to each other, as shown in FIG. 5, the spike claw 22 can be raised from the two or more linear portions 21a by bending and drawing. it can. That is, the spike claw 22 rising with the angle α can be easily obtained. In this way, when the adjacent side edges are raised in contact with each other, it can be considered as one spike claw 22, so this aspect is also “one spike claw” referred to in the invention according to the present application. As shown in FIG. 1, a plurality of spike claws are located at positions that are not adjacent to each other, and are different from a mode in which they are not continuous (separated). The adjacent spike claw pieces may be continuous in the horizontal direction as shown in FIG. 5 or may be separated in the horizontal direction and discontinuous.

  As the polygonal shape of the substrate 21, a triangle, a quadrangle, a hexagon, and the like shown in FIGS. 6A to 6C can be considered, and a circle shown in FIG. 6D can also be considered. In the case of these substrates 21, rotation is prevented (fixed at the rising angle β) by the protrusion 24 at any rotation angle (rising angle β). The substrate 21 of the above embodiment is a regular polygon except for FIG. 6D, but may be a polygon, and from the easiness of the spike claw 22 to start up, a concave portion (for example, a gear shape) is formed around it. Those without are preferred.

  When the substrate 21 has a polygonal shape, as shown in FIG. 7, as shown in FIG. 8 and FIG. 9A, if a convex frame 40 having the same shape in plan view on which the substrate 21 fits is formed on the lower surface of the outsole 11. In addition, the substrate 21 can be attached in a state in which the rotation of the substrate 21 is prevented by fitting the substrate 21 in the frame 40. At this time, if it is a regular polygon, the angle of its corner, for example, 60 degrees if it is a regular hexagon, and 72 degrees if it is a regular pentagon, the rising angle β of the spike claw 21 with respect to the toe direction. You can make changes. Moreover, when the board | substrate 21 is fitted to the frame 40, since the rotation of the board | substrate 21 is prevented by the fitting, the said sharp protrusion 24 can be abbreviate | omitted.

  Further, when the spike fitting 20 is rotated in the frame 40 to change the rising angle β of the spike claw 22, the spike claw 22 is bent from the substrate 21 so that there is no gap between the frame inner peripheral surface and the substrate 21 peripheral edge. It is necessary to process. For example, as shown in FIG. 9B, a notch 22a having a plate thickness is made at both rising edges of the spike claw 22 where the spike claw 22 is raised, and bending is performed at the tip (inner end) of the cut 22a ( As shown in FIGS. 8 and 9A, the peripheral shape of the frame 40 and the peripheral edge of the substrate 21 (the outer edge of the spike claw 22) are the same regular polygon in plan view. It is preferable to have a shape.

  As shown in FIGS. 10 and 11, the spike fitting 20 fitted to the frame 40 can be formed by bending the spike claw 22 continuous on two sides, three sides, etc. of the substrate 21 by bending drawing. . At this time, the spike claw 22 can be raised at a right angle to the substrate 21 as shown in FIG.

  The shape of the spike fitting 20 in the embodiment in which the frame 40 is provided is not limited to the above-described regular pentagon in plan view, but includes a regular triangle, a regular square, a regular hexagon, a regular octagon, and the like shown in FIGS. Furthermore, a regular heptagon, a regular pentagon, a regular decagon, a regular eleven, a regular dodecagon, a regular dodecagon, etc. are conceivable, but the spike claw 22 is continuous from two or more sides. In consideration of starting up by bending and drawing, it is preferable that each apex angle be 90 degrees to 135 degrees, such as a regular square to a regular octagon. In particular, a regular pentagon (vertical angle: 108 degrees) is more preferable, and the mounting strength by fitting into the frame 40 is also high.

  Thus, when the steel plate having the thickness of 1.2 mm is used and the spike claw 22 is continuously formed on two or more sides, the ridge portion continuing to each side has a “<” shape in a plan view. It is bent to become high rigidity. For this reason, on the substrate 21 having a thickness of 1.2 mm steel slab, a spike claw 22 having the same strength as the conventional (1.4 to 1.6 mm thick steel slab spike claw) can be obtained by punching and bending drawing. Incidentally, when the steel piece has a thickness of 1.4 mm or more, it is difficult to start up the bent shape when punching, bending and drawing, and the spike claw is likely to be broken at the base. For this reason, conventionally, if the strength can be ensured, the actual situation is that the character-shaped bending rise is not performed.

  Furthermore, as an aspect of the spike claw 22 provided on the substrate 21, as shown in FIGS. 13 (a) to 13 (h), the spike claw 22 is separated and provided on each side of the substrate 21, or continuously on two or more sides. Can be provided. When the plurality of spike claws 22 are provided, the height of each spike claw 22 can be changed.

Incidentally, as shown in FIG. 14, the substrate 21 and the spike claw 22 can be made into a three-dimensional shape, and this spike tool (metal fitting) 20 is optimal for a point-type spike.
The spike tool (metal fitting) 20 may be a cast / forged / cut product such as steel, aluminum or cemented carbide, a resin molded product, or the like. The shape is arbitrary such as a triangular pyramid shape, a triangular frustum shape, a quadrangular pyramid shape, a quadrangular pyramid shape, a conical shape, a truncated cone shape, a pentagonal pyramid shape, a pentagonal pyramid shape, and the like. These can be attached to any position of the outsole 11 by fastening means such as screws 30 and rivets. Further, the rising angle θ and the angle β may be arbitrary.
Furthermore, in these, if it is a regular polygonal pyramid, its plan view becomes a regular polygon. For example, as shown in FIG. 15, if a frame 40 corresponding to the regular polygon is formed on the bottom surface of the outsole 11, The rising angle β can be changed by rotation around the screw hole 23. At this time, as shown in the figure, if a seat 20a that fits in the frame 40 is provided at the bottom, no gap can be formed between the spike fitting 20 and the inner surface of the frame 40.

In addition, the rising angle θ of 72 to 75 degrees of the spike claw 22, the irregularity processing for forming irregularities on the surface of the substrate 21, the spike claw 22, the screw 30, etc., and the protrusion 25 on the periphery of the screw hole 23 are: The conventional spike fitting having a plurality of spike claws shown in FIG. 1 of Patent Document 1 can also be employed.
In the above embodiment, the rising angle θ of the spike claw 22: 72 to 75 degrees can be adopted not only for the buttocks, but also for the toe part, or only for one side. Of course, the rising angle θ can be made perpendicular to the outsole 11 in all the spike claws 22.
Further, in the embodiment in which the frame 40 is provided, the protrusions 24 can be provided on the substrate 21. The frame 40 does not have a convex shape on the lower surface of the outsole 11 as in the above embodiments, and a recess is formed on the lower surface of the frame 40 as long as the strength of the outsole 11 is not hindered. A fitting frame can also be configured.
