Description

toe divider shoes

The present invention relates to toe partition shoes, and particularly to toe partition shoes that suppress the infiltration of water from the toe partition portion.

Shoes with split toes are mainly distributed under names such as tabi shoes. Its characteristic is that the function of tabi (Japanese socks) is applied to shoes. Tabi has the advantage that the first toe (the big foot) and the second toe (the other toes) can move independently. For example, when standing or walking on uneven ground, the first toe and the other toes move separately, thereby improving the ease of gripping the ground with the toes. Therefore, toe partition shoes (Tabi shoes) are a good example of shoes that require complex toe movements for work, sports, etc. (see Patent Document 1, etc.).

For example, in the case of the toe partition shoe represented in Patent Document 1, the tip is divided into two, and the first toe of the foot is divided at a predetermined interval in the bifurcated portion of the interior member of the shoe that divides the first toe and the second toe of the foot. A member dividing the toe and the second toe into left and right sides is inserted. Then, the outside of the shoe, sole, etc. are attached and completed. In this way, in toe slats, the first toe (the thumb of the foot) is independently movable.

However, in the toe partition shoes represented in Patent Document 1, the shape of the nose portion of the shoe is more complicated than that of general shoes, so the number of parts is large and processing becomes complicated. In addition, because the shoe nose is divided into two parts, the adhesive parts of the shoe, such as the outer shell, insole, and sole, are likely to be vulnerable. In particular, in shoes with toe slats for work, sports, etc., increasing the rigidity of the two-pronged nose portion of the shoe hinders the free movement of the toes. On the other hand, if the toe of the shoe, which is divided into two parts, is made too flexible, the strength will decrease, and furthermore, water from the joint area between the members will penetrate into the shoe, causing discomfort, which is a problem.

Patent Document 1: Japanese Patent Laid-Open No. 2015-167670

The present invention was made in consideration of the above points, and in a shoe with a toe partition, the flexibility of the shoe nose portion divided into two is secured to enable free movement of the toes, and the shoe is separated from the joint area between the members. We provide shoes with toe slats that prevent the infiltration of water into the body and prevent discomfort.

That is, the toe partition shoe of the embodiment is a toe partition shoe having a partition between the first toe and the second toe of the foot, and the partition part forms the exterior of the toe partition shoe and is located at the outer skin tip of the shoe outer skin surrounding the foot. The joint of the first toe and the second toe of the foot at the distal outer skin part that enters the joint side of the first toe and the second toe and separates the first toe and the second toe of the foot, and the insole part disposed below the tip of the outer skin. A shoe bottom (sole) formed by entering the joint side of the first toe and the second toe of the foot from the insole cut-out portion formed by entering the side, and the tip of the shoe bottom of the shoe bottom disposed below the insole portion. It has a cutout portion, and the outer skin end of the separated outer skin enters from above the insole cutout portion and adheres to the back side of the insole portion around the insole cutout portion, and the bottom of the shoe is in close contact with the outer skin end and is in close contact with the insole portion.

Additionally, in the toe partition shoe, the separated outer skin may be formed by a single member, and the separated outer skin may be sewn and integrated with the outer skin tip.

Additionally, in the toe partition shoe, an insole curved portion (bending portion) may be formed in the insole portion that is in contact with the insole cut portion.

Additionally, in shoes with toe slats, a curved portion of the shoe sole may be formed in the shoe sole portion that is in contact with the shoe sole cut portion.

Additionally, in shoes with toe slats, a protective piece may be provided at the tip of the sole of the shoe.

Additionally, in the toe partition shoes, a protective piece notch may be formed in the protective piece portion.

According to the toe partition shoe of the present invention, it is a toe partition shoe having a partition between the first toe and the second toe of the foot, wherein the partition forms the exterior of the toe partition shoe and is positioned at the tip of the outer skin of the shoe outer skin surrounding the foot. The separate outer skin part that enters the joint side of the toe and the second toe and separates the first toe and the second toe of the foot, and the insole part disposed below the tip of the outer skin, and the joint side of the first toe and the second toe of the foot at the tip of the insole. an insole cutout portion formed by entering the insole portion, and a shoe bottom cutout portion formed by entering the joint side of the first toe and the second toe of the foot from the tip of the shoe bottom of the shoe bottom disposed below the insole portion, Since the outer skin end enters from the upper part of the insole cutout and adheres to the back side of the insole around the insole cutout, and the bottom of the shoe is in close contact with the outer skin end and adheres to the insole part, in a toe partition shoe, the shoe is divided into two parts. By ensuring the flexibility of the nose portion, free movement of the toes is possible, and also, by suppressing the infiltration of water into the shoe from the joint area between the members, discomfort is less likely to occur.

In the toe partition shoe 1 (also known as tabi shoe) of the embodiment shown in FIG. 1, the shoe nose 3, which is the tip of the shoe, is divided into two, and a partition portion 2 is formed between the first toe and the second toe of the foot. ) has. By the partition 2, the first toe of the foot (the thumb of the foot) is partitioned from the second to fifth toes and is independently movable. Therefore, free movement is possible, such as spreading the first toe away from the second toe and further bending the first toe and the second to fifth toes separately. For this reason, they are useful as shoes for work, sports, etc., which require adjustment of body balance, such as adjustment of movement of the body's center of gravity through the toes and maintenance of posture.

In such toe partition shoes 1, the structure is likely to be more complicated than that of a typical round shoe without a partition at the toe. Therefore, the toe partition shoe 1 of the embodiment has a configuration that satisfies the ease of movement of the first toe side of the foot and enhances the effect of suppressing water infiltration from the bifurcated portion of the toe. In the case of shoes for work, sports, etc., when used outdoors, the frequency of shoes getting wet by walking in puddles of water is high. From that point on, demand for waterproof specifications is high.

As shown in the perspective view of FIG. 1, the toe partition shoe 1 of the embodiment has the same overall structure as a normal shoe, and mainly includes an exterior 6 (upper) that forms the body of the shoe and surrounds the foot, and a shoe nose. (3), a heel (4), and an upper opening (5). And, a partition portion (2) is formed in the shoe nose (3). The exterior 6 is composed of a shoe outer skin 10 made of natural leather, synthetic leather, or synthetic resin. The exterior 6 is provided with a hole for passing a shoelace. Immediately below the exterior 6, a shoe bottom 30 called a sole is joined. In addition, the toe partition shoe 1 shown is a disclosure of one embodiment, and it is appropriate to use the shape, form, design, etc. of shoes other than those shown. Additionally, if necessary, shoe laces, spikes, etc. may be appropriately attached to the shoe outer skin 10 (not shown).

Figure 2 is an exploded perspective view showing the main components of the toe partition shoe 1. In order from the top, the toe partition shoe (1) mainly includes a shoe outer skin (10), an insole portion (20), and a shoe sole portion (30). Additionally, an inner sole (midsole), fabric, cushion member, thickness adjustment member, protective steel plate, etc. not shown may be added as needed.

The shoe outer skin 10 forms the exterior 6 of the toe partition shoe 1 and wraps the toes, instep, and heel of the person wearing the shoe. In addition, the shoe outer skin portion 10 is a member that reinforces the shoe nose 3 of the toe partition shoe 1 and is provided with a outer skin tip portion 11. The shoe outer skin portion 10 and the outer shoe tip portion 11 may be formed as one fabric or member, or may be combined as separate pieces. And, the separated outer skin portion 13 is provided at the outer skin end portion 11 of the shoe outer skin portion 10. A partition 2 is formed at the tip 11 of the outer shell of the shoe nose 3. The partition portion (2) is a member that divides the first toe and the second toe of the foot, and the separation outer skin portion (13) serves to divide the first toe and the second toe. The separation outer skin portion 13 is a member that enters the joint 12 side of the first toe and the second toe of the foot from the outer outer end portion 11 and separates the first toe and the second toe of the foot.

The insole portion 20 is a member disposed below the shoe outer skin portion 10 and in contact with the sole of the foot of the person wearing the shoe. The insole portion 20 is joined to the shoe outer skin portion 10 by adhesive. The toes, instep, and heel of the person wearing the shoe are surrounded by the shoe outer skin portion 10, and the sole is surrounded by the insole portion 20. wrapped and protected. The insole portion 20 is formed with an insole cut portion 23 that enters from the insole distal end 21 toward the joint 22 of the first toe and the second toe of the foot. The insole cutout portion 23 is a cutout-shaped portion for increasing the mobility of the first toe and the second toe, and in the embodiment, has a long U shape.

The shoe sole portion 30 is disposed below the insole portion 20, is in direct contact with the ground, and is a member that alleviates impact when grounding. The shoe sole portion 30 is joined to the insole portion 20 by adhesive. The shoe sole portion 30 is formed with a shoe sole cut portion 33 that enters from the shoe sole distal end 31 toward the joint 32 of the first toe and the second toe of the foot. The shoe bottom cut-out portion 33 is a cut-shaped portion for increasing the mobility of the first toe and the second toe, and in the embodiment, has a long U-shape like the insole cut-out portion 23. Additionally, a protective piece portion 35 is provided at the tip portion 31 of the shoe sole portion 30 of the embodiment. Additionally, a protective piece cut portion 36 is formed in the protective piece portion 35.

Figure 3 is a plan view showing an enlarged portion of the partition portion 2 of the toe partition shoe 1. As understood from FIGS. 2 and 3, the partition portion 2 of the toe partition shoe 1 extends from the upper shoe outer skin 10 to the lower shoe sole 30, and the shoe nose 3 When viewed from the front, it is formed to be separable into left and right sides. Accordingly, the first toe of the foot (the thumb of the foot) can move up and down or left and right independently from the other second to fifth toes, and the range of motion of the first toe is expanded.

Figure 4 is a front schematic diagram showing the separated outer skin portion 13, which is configured as the partition portion 2 of the shoe outer skin portion 10, expanded. As can be understood from the illustration, the separate skin portion 13 is formed by a single member. In particular, it is made of the same material as the outer tip 11 of the shoe outer skin 10, such as natural leather, synthetic leather, or synthetic resin. Then, the separate outer skin portion 13 of a single member is sewn to the outer skin tip 11 side of the shoe outer skin portion 10 and integrated. The symbol '14' in the drawing is a cut-out adhesive portion, which will be explained later in FIG. 6.

In order to form a partition portion (2) at the distal end portion of the outer skin (11) to separate the first toe and the second toe by the separation outer skin portion (13), a detailed curvature corresponding to the toe is required. The curved portion is formed by adjusting the seam allowance when sewing multiple members. When the partition part is divided into fine parts and sewn to form the curved part, the sewing process increases and the weight increases. Additionally, it becomes easy for water to penetrate from the sewn portion. Therefore, in order to form a curved portion by both suppressing water infiltration and reducing the sewing portion, the separate outer skin portion 13 is made into a single member, like the separate outer skin portion 13 in FIG. 4, and the separate outer skin portion 13 ) and the outer shell distal end 11 side are integrated by sewing.

Figure 5 is a schematic diagram showing the positional relationship of the separated outer skin portion 13 encroaching on the insole cutout portion 23. The separated outer skin portion 13 is bent into a V shape in plan view and sewn to the outer skin distal end 11 (see Fig. 4). Then, the bent separate outer skin portion 13 is inserted into the insole cutout portion 23. As shown, the separated outer skin portion 13 is in contact with the insole cutout portion 23 of the insole tip portion 21 of the bifurcated insole portion 20. In this way, the shoe nose 3 is divided into two sections: the first toe of the foot (the thumb of the foot) and the second to fifth toes.

Figure 6 is a partially enlarged bottom view of the insole portion 20 near the insole tip portion 21. The outer skin ends (cut-out adhesive portion 14, adhesive portion 15) of the separated outer skin portion 13 enter from the upper side of the insole cut-out portion 23 and penetrate the insole portion 20 around the insole cut-out portion 23. It is attached to the bottom surface portion 28 of the shoe on the back side. And, as shown in Figures 1, 3, etc., the shoe bottom 30 is in close contact with the outer shell end (cut adhesive portion 14, adhesive portion 15) and is in close contact with the insole portion 20.

In the city, the shoe outer skin 10 is covered with the insole portion 20 and fixed in a predetermined position, and the adhesive portion 15 (the portion left for gluing) that bonds the shoe outer skin 10 and the insole portion 20 is It appears. Then, the adhesive portion 15 is bent and adhered to the insole bottom portion 28 of the insole portion 20, and the shoe outer skin portion 10 is fixed to the insole portion 20. At the same time, the bent separate outer skin portion 13 is inserted into the insole cutout portion 23 (see Fig. 5), and the cut adhesive portion 14 of the separate outer skin portion 13 (a portion reserved for gluing) is also revealed. The cut adhesive portion 14 is also bent like the adhesive portion 15 and is bonded to the insole bottom portion 28 of the insole tip portion 21 around the insole cut portion 23 (see Fig. 5). In addition, the cut adhesive portion 14 is provided with an appropriate cut portion to correspond to the U-shaped cut shape of the insole cut portion 23, and the ease of bending is improved in addition to the flexibility of the material itself. there is.

It cannot be denied that the structure of the partition portion 2 tends to be complicated, so when it is desired to suppress the infiltration of water from the sewn portion as much as possible, a single water-resistant material is used, as in the separation outer skin portion 13 of the embodiment. It is preferable that it be formed as a member with character. Therefore, the separation outer skin portion 13 is formed with a sufficient length required to provide the cut adhesive portion 14. For this reason, the partition portion 2 is constructed without damaging the integrity of the separation outer skin portion 13. In particular, the area around the joints 12, 22 of the first toe and the second toe of the foot when grounded is protected without damage by bending of the outer skin 13 and the cut adhesive portion 14, thereby improving water resistance performance. improves.

FIG. 7 (a) is a partially enlarged plan view of the insole tip portion 21 of the insole portion 20, and FIG. 7 (b) is a cross-sectional view taken along line A-A in the same figure (a). An insole curved portion 24 is formed on the insole portion 20 that is in contact with the insole cut portion 23. That is, the insole curved portion 24 is formed around the U-shape of the insole cutout portion 23 including the joint 22. Additionally, in the insole portion 20 of the embodiment, the insole curved portion 24 is formed around the entire periphery of the insole portion 20.

The insole curved portion 24 is formed around the U-shape of the insole cut portion 23, thereby creating a round on the insole bottom portion 28 (see Fig. 6) side of the partition portion 2. Therefore, when the cut adhesive portion 14 of the separate outer skin portion 13 is attached to the bottom surface portion 28 of the insole cut portion 23, the cut adhesive portion 14 is formed at the corner due to the curvature of the insole curved portion 24. It is not easily damaged. In addition, the curvature of the insole curved portion 24 follows the shape of the first toe (big foot) and the second toe of the foot, and the wearing comfort of the shoe is improved.

Figure 8(a) is a partially enlarged plan view of the shoe sole tip 31 of the shoe sole 30, and Figure 8(b) is a cross-sectional view taken along line B-B in the same figure (a). A shoe sole curved portion 34 is formed on the shoe sole portion 30 in contact with the shoe sole cutout portion 33. That is, the shoe sole curved portion 34 is formed around the U-shape of the shoe sole cutout portion 33 including the joint 32. Additionally, in the shoe sole 30 of the embodiment, a shoe sole curved portion 34 is formed around the entire circumference of the shoe sole 30. The illustration is a schematic cross-sectional view, and if necessary, the back side (tread surface) of the shoe bottom 30 is provided with appropriate shoe grooves, anti-slip surfaces, spikes, etc. (not shown).

By forming the shoe sole curved portion 34 around the U-shape of the shoe sole cut portion 33, the adhesion with the insole portion 20 provided with the insole curved portion 24 of FIG. 7 described above is improved. The inclination and curvature of the curved portion of the shoe sole 34 are determined by the curved portion of the insole 24, the thickness of the incised adhesive portion 14 and the adhesive portion 15 attached thereto, and the wrinkles of the adhesive portion 15 that are formed by bending. The thickness, etc. are taken into consideration and specified. In this way, the integrity of the insole curved portion 24 of the insole portion 20 and the shoe bottom curved portion 34 of the shoe bottom 30 is increased, and when the first toe of the foot (the thumb of the foot) is moved, the partition portion ( In 2), followability to the movement of the first toe increases, and fit and mobility improve.

Here, as can be understood from FIGS. 2, 3, and 8, the shoe sole tip portion 31 is provided with a protective piece portion 35. The protective piece portion 35 may be made of the same member as the shoe sole portion 30, or may be separately joined to the shoe sole portion 30 and other members. In the embodiment, the shoe sole portion 30 is composed of two layers of synthetic resin material, and the outermost ground portion is extended to form a protective piece portion 35. The protective piece portion 35 protects the shoe nose 3 and the outer shell tip portion 11 from impact. In the case of shoes for work, sports, etc., the shoe nose 3 is prone to hitting other objects. In addition, with the conventional round shoe toes, the shock can be distributed throughout the entire shoe nose, and the shock to the toes is alleviated. However, since the toe partition shoe 1 is provided with the partition portion 2, the impact cannot be distributed throughout the shoe nose. Therefore, the protective piece portion 35 receives the shock in advance, making it difficult for the shock to be transmitted directly to the first toe and the second toe within the separate outer skin portion 13.

Additionally, a protective piece cut portion 36 is formed in the protective piece portion 35. The protective piece cut portion 36 is formed as a partition portion 2 to separate the left and right sides. For example, if the protection piece portion 35 is made of a single connection member, the mobility of each toe in the partition portion 2 is reduced by the single connection protection piece portion 35. Therefore, a protective piece cutout portion 36 is provided in the protective piece portion 35, and the shoe sole cutout portion 33 is made independently movable between the first toe and the second toe.

As a series of explanations, in the toe partition shoe 1 (Tabi shoe), the first toe and the second to fifth toes of the foot are made independently movable by the partition, and the body's center of gravity is moved through the toes. They are useful as shoes for work, sports, etc. that require adjustment of body balance, such as coordination and posture maintenance. Additionally, the partition portion separating the first toe and the second toe of the foot is sewn without complicating the structure, and the effect of suppressing water infiltration into the two-pronged portion of the partition portion, mainly the joint portion, is increased. Accordingly, the discomfort of getting wet when the shoes are continuously worn is reduced.
