Description

  The present invention relates to a sports shoe and a toe protection member that is a constituent member of the sports shoe and protects a toe portion.

  Various types of sports shoes are known according to each application. As an example, there are baseball and softball shoes (commonly called spike shoes), but in baseball and softball, the toe part is rubbed against the ground each time a pitching operation is performed. Is prone to local wear. Especially for pitchers that repeat pitching movements, especially for softball pitcher spike shoes that throw with a pitching method (called windmill pitching method) that drags while keeping your dominant foot on the ground. Cheap. For this reason, there is known a spike shoe to which a toe protection member for protecting the spike shoe from local wear is attached.

  For example, in Patent Document 1 below, a protector A (toe protection) comprising a protector body 1 formed in a shape covering the toe portion of the spike shoe B and a protective metal fitting 2 attached to the tip of the protector body 1. Member). By attaching the protector A so as to cover the toe portion of the spike shoe B, the spike shoe B can be protected from local wear of the toe portion.

  By the way, even if it is a spiked shoe to which the toe protection member is attached, since the toe part (toe protection member) is repeatedly rubbed against the ground, it is worn out, and it is necessary to replace the toe protection member as necessary. In Patent Literature 1, the nail 13 is hit against the bottom of the toe of the spike shoe B, and the protector A is attached to the spike shoe B. Replacement of the protector A is performed by removing the worn nail 13 and removing the worn protector A, and then driving the nail 13 and attaching a new protector A. For this reason, if the replacement of the protector A is repeated, there is a problem that the bottom of the toe of the spike shoe B is damaged and it becomes difficult to drive the nail 13 and the replacement of the protector A becomes difficult.

  There are also a method of making a hole and sewing and fixing the toe protection member with a string, and a method of sewing with a sewing machine. However, both methods require a tool for installation and skilled techniques, and there is a problem that it takes time to perform the installation work.

  The present invention has been made in view of such a problem, and an object thereof is to provide a sports shoe having a toe protection member that can be attached and detached without damaging the shoe body, and the toe protection member.

In order to achieve the above object, a sports shoe according to the present invention comprises a sports shoe body and a toe protection member that covers and attaches the toe portion of the shoe body to protect the toe portion. The toe protection member is configured to have an inner surface shaped to cover the toe part, and the toe protection member is adhesively bonded to the inner surface by applying an adhesive to the inner surface. The adhesive has an adhesive strength that can withstand normal use of the sports shoes against a shearing force to move the toe protection member relative to the toe part along the adhesion surface, Adhesive strength in a direction perpendicular to the direction of the shearing force that separates the toe protection member from the toe portion allows the toe protection member to be peeled off without damaging the shoe body Characterized in that it is a strength.

  In the above sports shoes, preferably, the upper front portion of the shoe body is provided with a plurality of shoelaces for shoelaces, and the upper front portion is tightened by tying shoelaces through the plurality of cord holes. The toe protection member has a holding part extending to a position covering at least one of the string holes on the upper surface, and a holding part string hole is formed in the holding part to match the string hole covered by the holding part, A toe protection member is applied to the inner surface excluding the inner surface of the holding part and adhered to the toe part, and the holding part ties the shoelace through the shoe hole and the holding part string hole. By this, it is the structure attached and hold | maintained to the said shoe main body.

  In the sports shoes, more preferably, a reinforcing member made of a highly wear-resistant material is attached to the front end surface of the toe protection member.

  On the other hand, the toe protection member according to the present invention is a toe protection member constituting the above-described sports shoes, and is configured to cover the toe part of the shoe body with the adhesive.

  According to the sports shoes of the present invention, the adhesive strength for bonding the toe protection member to the toe part of the shoe body is against the shearing force to move the toe protection member relative to the toe part along the adhesion surface. Because it has adhesive strength that can withstand normal use of this sport shoe, the toe protection member does not come off during sports, and the toe part of the shoe body is securely attached to the toe protection member It can protect and prevent wear and damage of the toe part. On the other hand, the force in a direction perpendicular to the shearing direction, that is, the adhesion force to the peeling force in the direction of separating the toe protection member from the toe part of the shoe body, is a strength that can tear off the toe protection member without damaging the shoe body. Therefore, when the toe protection member is worn, etc., it is possible to peel off the toe protection member without damaging the shoe body, and attach a new toe protection member with an adhesive, and use the shoe body repeatedly. it can.

  Further, the sports shoe according to the present invention is configured to be fixed to the foot by tying the shoelace through a lace hole provided in the upper front portion of the shoe body, and covering at least one of the lace hole on the upper surface of the toe protection member It is preferable that a holding portion extending to the position is provided and the holding portion cord hole provided in the holding portion is passed through and tied together when the shoelace is passed through the shoe hole. In this case, it is preferable to apply an adhesive to the inner surface except the inner surface of the holding part of the toe protection member and adhere to the toe part. In this way, since the shoelace is tied to the strap hole and the holding strap hole, the toe protection member can be firmly held on the shoe body by the shoelace in addition to the adhesive bonding, and the holding portion that is not bonded Further, it is possible to prevent the force in the direction of peeling it from the shoe body. In addition, when the toe protection member is worn out or damaged and replaced with a new one, the unattached holding part is released if the shoelace is removed. The force in the peeling direction can be easily applied, and the toe protection member can be easily peeled off from the shoe body.

In the above sports shoes, a reinforcing member made of a highly wear-resistant material may be attached to the front end surface of the toe protection member. By attaching the reinforcement member in this way, the strength of the toe protection member is increased and the service life thereof is extended. can do.

  On the other hand, the toe protection member according to the present invention is a toe protection member that constitutes the above-described sports shoes, and is attached to cover the toe part with an adhesive. The resulting sports shoes can be provided.

It is a perspective view which shows the spike shoe main body (state which removed the shoelace) which comprises this spike shoe. It is a figure which shows the toe | tip tip protection member which comprises the said spike shoes, Comprising: Fig.3 (a) is the top view, FIG.3 (b) is the side view, FIG.3 (c) is the bottom view. It is sectional drawing which shows the IV-IV part of the spike shoes shown in FIG. It is a perspective view which shows the spike shoes which concern on another embodiment of this invention. FIG. 6A is a plan view, FIG. 6B is a side view, and FIG. 6C is a bottom view of a toe protection member that constitutes another spike shoe. .

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a spike shoe 3 for softball as an example of a sports shoe according to the present invention. Although FIG. 1 shows the spike shoe 3 for the right foot, the same configuration can be used for the left foot. The spike shoe 3 is configured by attaching the toe protection member 1 shown in FIG. 3 to the toe portion of the shoe body 2 shown in FIG.

  As shown in FIG. 2, the shoe body 2 includes a sole 21 that forms the bottom, an upper 22 that is connected to the peripheral edge of the sole 21 and extends upward, and is attached to the toe side of the upper 22 to cover the upper part of the foot. It comprises a tongue piece 23 and a shoelace 24 for connecting and fastening the front portion of the upper 22 to fit and fix the spiked shoe 3 to the foot. FIG. 2 shows a state in which the shoelace 24 is removed.

  A plurality of spikes 21 a protruding downward are provided on the lower surface of the sole 21. A foot opening 24 is formed on the rear side of the upper 22, and a front opening 25 is formed on the front side and is closed by the 23. A plurality of lace holes 26 through which the shoelaces 24 are passed are provided in the front part of the upper 22 in the front-rear direction, and the shoelaces 24 are attached therethrough as shown in FIG.

  As shown in FIG. 3, the toe protection member 1 attached to the toe part of the shoe body 2 includes a front cover part 11 formed in a curved shape that protrudes forward so as to cover the outer surface of the toe part 27, and The lower cover 12 is connected to the lower part of the front cover 11 and extends in the horizontal direction, and the upper cover 13 is connected to the upper part of the front cover 11 and extends rearward.

  The front cover 11 includes a curved main body 14 that protrudes forward, and a reinforcing member 15 attached to the front surface of the main body 14. The main body 14 is formed using, for example, a resin material, leather, or the like. The reinforcing member 15 extends from the metal plate material to the left and right, and is attached along the front surface of the main body portion 14 using bolts 16 and nuts 17 (see also FIG. 4). The reinforcing member 15 may be made of a material other than a metal material, for example, a material having high wear resistance such as reinforced plastic or FRP. The attachment method of the reinforcing member 15 to the main body 14 is not limited to the method of fastening using the bolt 16 and the nut 17, and other attachment methods such as adhesion may be used.

The lower cover portion 12 is formed using a resin material, leather, or the like, and is a portion that covers the front portion of the sole 21 from the lower side when the toe protection member 1 is attached to the shoe body 2. The upper cover portion 13 is formed of resin, leather, cloth, or the like, and is a portion that covers the toe portion 27 from above in a state where the toe protection member 1 is attached to the shoe body 2. As can be seen from this, the toe protection member 1 has an inner surface space shaped so as to be in close contact with and cover the toe portion 27 of the shoe body 2.

  The toe protection member 1 has a desired adhesive strength and is attached to the toe portion 27 of the shoe body 2 by using an adhesive S that can be peeled off. The adhesive S has an adhesive strength that prevents the adhesive S from being peeled by a shearing force acting on the toe protection member 1 during use of the spike shoe 3. That is, it has sufficient adhesive strength that can withstand the force in the shearing direction caused by normal use of the spike shoe 3. On the other hand, the adhesive force with respect to the peeling force in the direction perpendicular to the shearing direction, that is, the direction in which the toe protection member 1 is separated from the toe portion 27 of the shoe body 2 is not so large. Specifically, the adhesive strength is such that when the force in the direction away from the toe portion 27 of the shoe body 2 is applied to the toe protection member 1, the toe protection member 1 can be removed without damaging the shoe body 2. Such an adhesive S has been known and put into practical use for more than 20 years. For example, there is a product name “SEICA GROUT PACK 1” manufactured by Nippon Sika Co., Ltd. The component and content of the adhesive S are 40 to 50% for the modified silicone polymer, 1 to 2% for the colorant (such as titanium oxide), 55 to 60% for the inorganic filler, and 0.5 to 0.5% for the organometallic compound. 0.9%.

  If this adhesive S is applied to the inner surface of the toe protection member 1 and adhered to cover the toe portion 27 of the shoe body 2, the inner surface of the toe protection member 1 is brought into close contact with the outer surface of the toe portion 27. Adhesive joining is performed to complete the spike shoe 3. FIG. 4 shows a cross-sectional view of a state in which the toe protection member 1 is attached to the toe portion 27 using the adhesive S. In FIG. 4, the thickness of the adhesive S is exaggerated and thick, but it is actually a thin layer.

  The spike shoe 3 according to the present embodiment is suitable for use by, for example, a softball pitcher. As described above, in the softball, the toe portion is rubbed against the ground every time the pitching operation is performed, and thus this portion is likely to be locally worn, but the toe protection member 1 prevents the toe portion from being worn. In the softball, the toe portion is easily worn by the windmill throwing method or the like while the dominant foot is attached to the ground, and the toe portion is particularly easily worn, but the toe protection member 1 effectively prevents this. At this time, the wear prevention effect is enhanced by the reinforcing member 15 attached to the front surface of the front cover portion 11.

  As described above, since the toe protection member 1 is attached with the adhesive S, the adhesive strength will be described. When the pitching operation as described above is performed while wearing the spike shoes 3, the toe protection member 1 is rubbed against the ground, and a force in the direction along the adhesive layer of the adhesive S acts on the shoe body 2 from the toe protection member 1. To do. That is, a shearing force mainly acts on the adhesive layer. As described above, the adhesive S has an adhesive strength that does not peel off against the force in the shearing direction that acts on the toe protection member 1 during normal use in sports performed by wearing spike shoes 3. There is no possibility that the toe protection member 1 is peeled off during use.

  However, if the use is repeated, it is inevitable that the toe protection member 1 is gradually worn, and it is necessary to remove it from the shoe body 2 and replace it with a new toe protection member 1. At this time, a force in the direction of separating the toe protection member 1 from the shoe body 2, that is, a peeling force is applied. As described above, the adhesive S does not have a large adhesive force with respect to the peeling force in the direction perpendicular to the shearing direction, that is, the direction in which the toe protection member 1 is separated from the toe portion 27 of the shoe body 2 and damages the shoe body 2. The toe protection member 1 can be removed without any trouble. As described above, when the toe protection member 1 is peeled off, an adhesive layer may remain on the toe portion of the shoe body 2, but in the case of the adhesive S layer, it can be easily peeled off.

  After the toe protection member 1 thus worn is peeled off and removed from the shoe body 2, the replacement is completed when the new toe protection member 1 is attached to the toe portion of the spiked shoe 2 again using the adhesive S. To do. For this reason, the toe protection member 1 that has been worn can be easily attached and detached as necessary, and the shoe body 2 can be used continuously without causing local wear on the shoe body 2.

  Instead of the above-described toe protection member 1 (toe protection member 1 shown in FIGS. 1 and 3), a toe protection member 1 'shown in FIGS. 5 and 6 may be used. The toe protection member 1 ′ is different from the toe protection member 1 shown in FIGS. 1 and 3 in that the rear portion of the upper cover portion 13 ′ extends rearward and a holding portion 13a is provided. A shoelace 24 is attached to the holding portion 13a. The difference is that a holding portion string hole 13b that can be inserted is formed. Similarly to the toe protection member 1 shown in FIGS. 1 and 3, this toe protection member 1 ′ is coated with an adhesive S on the inner surface of the toe protection member 1 and bonded to the toe portion 27 of the shoe body 2. . However, at this time, the adhesive S is applied to the inner surface of the toe protection member 1 ′ except for the inner surface region of the holding portion 13a (the region indicated by the hatching of the dotted line in FIG. To do. That is, the holding part 13a in which the string hole 13b is formed is not bonded.

  When the toe protection member 1 ′ is bonded to the toe portion 27 in this manner, the holding portion string hole 13 b is aligned with the foremost string hole 26 on the left side of the shoe body 2. Therefore, the shoelace 24 is attached to the strap hole 26 and the holding strap hole 13b (see FIG. 5). If the shoelace 24 is tied in this state, as shown in FIG. 5, the toe protection member 1 ′ is held in the shoe body 2 by the shoelace 24 in addition to adhesive bonding. As a result, it is possible to prevent the force in the direction of peeling the toe protection member 1 ′ from the shoe body 2 from acting on the non-bonded holding portion 13 a.

  On the other hand, when the toe protection member 1 ′ is worn and damaged and replaced with a new one, if the shoelace 24 is removed, the unbonded holding portion 13 a is released. Therefore, a force in the direction of peeling off from the shoe body 2 can be easily applied to the toe protection member 1 ′ by grasping the holding portion 13a, and the toe protection member 1 ′ can be easily peeled off from the shoe body 2. it can.

  In the embodiment described above, the spike shoes used for baseball and softball have been described as examples of sports shoes whose toe portions are likely to be locally worn. The toe protection member 1 according to the present invention may be attached to sports shoes used in sports where the toe portion other than baseball and softball is likely to be locally worn. In this case, the toe protection member is also necessary. If 1 is attached and detached, the sports shoes can be used continuously without causing local wear on the sports shoes.

  In the above-described embodiment, the configuration in which the toe protection member 1 is attached to a sports shoe (the shoe body 2) that is tightened by the shoelace 24 is described as an example. It is also possible to attach the protective member 1.
