[Technical Field]

[0001] The present invention relates to sandals. [Background technology]

[0002] 2. Description of the Related Art Various sandals have been proposed in the past that do not cover the entire foot of a user but are secured to the sole with a string, band, or the like.

[0003] For example, Patent Document 1 describes a sandal that has a sandal base, an instep band attached to the sandal base, and a hemispherical or cylindrical protrusion attached to the underside of the sandal base at a position corresponding to the subcapital area of ​​the first metatarsal bone or the subcapital areas of the second and third metatarsal bones. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2022-070456 Summary of the Invention [Problem to be solved by the invention]

[0005] However, because the sandals described in Patent Document 1 have a fixed size for the instep band, it is difficult for sandals suitable for holding the user's toes (toe side) to properly hold the user's ankle area.Similarly, it is difficult for sandals described in Patent Document 1 suitable for holding the user's ankle area to properly hold the user's toes (toe side). Additionally, depending on the size of the user's feet, it may be difficult to insert the foot into the band.

[0006] The present invention has been made in consideration of the above-mentioned circumstances, and its object is to provide sandals that can be worn on the user's feet even if the position of the user's feet is different. [Means for solving the problem]

[0007] In order to solve the above problem, the present invention provides a sandal comprising a sole portion that contacts the sole of the user's foot and a holding portion that holds the user's foot, the holding portion being positioned directly above the center of gravity of the sole portion and configured so that the length of the inner circumference can be adjusted.

[0008] According to the present invention, the length of the inner circumference of the holding portion can be changed depending on the position of the user's foot, so that sandals can be fitted to the user's foot even if the position of the user's foot being held is different. Furthermore, the length of the inner circumference of the holding portion can be changed depending on the size of the user's foot, so that the sandals can be worn regardless of the size of the user's foot. Furthermore, since the holding portion is positioned directly above the center of gravity of the sole portion, it is easy to maintain balance when wearing the sandals.

[0009] In a preferred embodiment of the present invention, the holding portion has erected portions that stand opposite both ends of the sole portion in the front-to-rear direction, and a holding portion main body that extends from the erected portions, and the holding portion main body includes a first holding portion component and a second holding portion component, and the length of the inner circumference of the first holding portion component or the second holding portion component can be adjusted by changing the relative position of the first holding portion component or the second holding portion component. With this configuration, the opening of the holding portion is maintained when no external force is applied, which contributes to improving the breathability of the sole portion.

[0010] In a preferred embodiment of the present invention, the first holding part constituent or the second holding part constituent is provided with fixing means capable of fixing the adjusted length of the inner circumference. By adopting such a configuration, it is possible to maintain the length of the inner circumference of the holding portion at an appropriate size.

[0011] In a preferred embodiment of the present invention, the bottom surface of the sole portion is formed in a downwardly convex curve in a side view. With this configuration, when a user stands on his / her own, he / she needs to use his / her trunk to maintain balance from front to back, so it is possible to train the trunk and sense of balance.

[0012] In a preferred embodiment of the present invention, the convex apex of the curve is located directly below the center of gravity of the sole portion. This configuration makes it relatively easy for the user to maintain balance when standing upright.

[0013] In a preferred embodiment of the present invention, the sole portion is truncated on the heel side. This configuration shortens the distance from the end of the sole to the center of gravity of the sandal, making it relatively easier for the user to balance themselves when standing on their own.

[0014] The top surface of the sole portion is formed in an upwardly convex curve in a side view. This configuration improves the holding performance of the holding part, and at the same time, the opening of the holding part becomes relatively wider, making it easier to put on. [Effects of the Invention]

[0015] According to the present invention, it is possible to provide sandals that can be worn on the user's feet even when the user's feet are in different positions. [Brief explanation of the drawings]

[Figure 7] 1 is a diagram illustrating a method of using the sandal according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0017] Sandals according to an embodiment of the present invention will be described below with reference to Figs. The following embodiment is an example of the present invention, and the present invention is not limited to the following embodiment. In these figures, the symbol X indicates a sandal for the right foot according to this embodiment. In an actual embodiment, a sandal for the left foot also exists. However, since the sandal for the left foot is symmetrical to the sandal for the right foot X, the description in this specification will be implemented in the same manner, with "for the right foot" being read as "for the left foot." In particular, a detailed description of the sandal for the left foot will be omitted in this specification. Here, the heel side means the side (rear side) on which the user's heel is placed when the user puts on the right sandal X, and the toe side means the side (front side) on which the user's toes are placed when the user puts on the right sandal X. In addition, the front-to-back direction means the direction connecting the heel side and the toe side, the width direction means the direction perpendicular to the front-to-back direction in a planar view, and the height direction means the direction perpendicular to both the front-to-back direction and the width direction. In addition, in the sole portion, the top surface means the surface on which the user's foot rests, and the bottom surface means the surface that comes into contact with the ground.

[0018] <Configuration> As shown in FIG. 1, the right sandal X includes a sole portion 1 that comes into contact with the sole of the user's foot, and a holding portion 2 that holds the user's foot.

[0019] Since the sole part 1 and the holding part 2 form a cylindrical shape, the holding part 2 can hold the user's foot.

[0020] As shown in FIGS. 2 and 3, the sole portion 1 is shortened on the heel side.

[0021] As shown in FIG. 4, the bottom surface of the sole portion 1 is formed in a downwardly convex curve in a side view. More specifically, the apex of the downwardly convex curve is located directly below the center of gravity of the sole portion.

[0022] As shown in FIG. 4, the top surface of the sole portion 1 is formed in an upwardly convex curve in side view. More specifically, the convex apex of the curve is located directly above the center of gravity of the sole portion. This allows the right sandal X to be stored in an upright state when not in use.

[0023] The sole portion 1 also has a pressing portion 11 that presses against the sole of the user's foot, and a groove portion 12 that prevents the bottom surface of the sole portion 1 from slipping.

[0024] The pressing portion 11 is formed in a semi-spherical shape. This makes it possible to stimulate the pressure points on the soles of the user's feet. In this embodiment, the material of the pressing portion 11 is formed from the same material as the top surface of the sole portion 1, but it may be a different material as long as it has enough rigidity to stimulate the acupressure points on the soles of the user's feet.

[0025] Moreover, a plurality of pressing portions 11 are provided on the top surface of the sole portion 1. More specifically, the pressing portions 11 are arranged in a row in the front-rear direction, and the row is further arranged in a plurality of rows along the width direction. This allows the pressing portion 11 to stimulate the acupressure points on the soles of the user's feet, regardless of the positions of the acupressure points on the soles of the user's feet.

[0026] The groove portion 12 is provided on the bottom surface of the sole portion 1.

[0027] As shown in FIG. 3 in particular, the grooves 12 are formed in the shape of a rounded rectangle with the longer sides extending in the width direction when viewed from the bottom, and a plurality of grooves 12 are provided at equal intervals along the front-rear direction. This prevents the user from sliding back and forth when wearing the right sandal X, since the user sways back and forth. Furthermore, since the edges forming the grooves 12 come into contact with the ground, it becomes relatively easy to maintain balance.

[0028] As shown in FIGS. 4 to 6, the holding part 2 has erected parts 21 erected opposite to each other in the width direction from both ends of the sole part 1, and a holding part main body 22 extending from the erected parts 21. In this embodiment, nylon is preferably used as the material for the standing portion 21 and the holding portion main body 22, but there are no particular limitations as long as the material has enough rigidity to maintain its shape when not subjected to external force. Also, the materials for the standing portion 21 and the holding portion main body 22 may be different.

[0029] The standing portion 21 includes a first standing portion constituent 21a and a second standing portion constituent 21b.

[0030] The first standing portion constituent 21a and the second standing portion constituent 21b maintain an upright state when not subjected to an external force. This makes it possible to hold an opening formed by the first holding part constituent 22a and the second holding part constituent 22b, which will be described later.

[0031] The first standing portion constituent 21a and the second standing portion constituent 21b are formed so that the length in the front-rear direction from the sole portion 1 along the height direction gradually becomes shorter. This allows the standing portion 21 to maintain its standing state when not subjected to external force, and contributes to reducing the manufacturing cost and weight of the holding portion 2.

[0032] The holding portion main body 22 includes a first holding portion constituent 22a extending from the first standing portion constituent 21a and a second holding portion constituent 22b extending from the second standing portion constituent 21b.

[0033] The first holding part constituent 22a and the second holding part constituent 22b form the inner periphery of the holding part 2 into which the user's feet are inserted, and are configured so that the length of the inner periphery can be adjusted by changing the relative positional relationship between them.

[0034] The first holding part constituent 22a and the second holding part constituent 22b are provided with fixing means F for fixing them together. This makes it possible to fix the length of the inner circumference of the holding portion main body 22.

[0035] The fixing means F is, for example, a hook-and-loop fastener. This makes it easy to fix or release the first holding part constituent 22a and the second holding part constituent 22b to each other. Moreover, it becomes possible to fix the first holding part constituent 22a and the second holding part constituent 22b regardless of the size of the inner circumference.

[0036] <How to use> Hereinafter, a method of using the right sandal X will be described with reference to FIGS. The left sandal (shown) is used in the same way as the right sandal X.

[0037] When putting on the right sandal X on the user's foot (not shown), the user first releases the fastening means F as shown in FIG.

[0038] Next, the user places his / her foot on the top surface of the sole portion 1. At this time, the user's feet (not shown) are positioned so that the holding portion 2 can hold the user's feet.

[0039] Next, the user covers the first holding part constituent 22a and the second holding part constituent 22b on the user's feet (not shown). At this time, the user adjusts the length of the inner circumference of the holding part main body 22 by changing the relative positions of the first holding part constituent 22a and the second holding part constituent 22b according to the holding part of the user's foot (not shown) and the size of the foot.

[0040] Next, the user uses the fixing means F to fix the first holding part constituent 22a and the second holding part constituent 22b together.

[0041] This allows the user to wear the right sandal X regardless of the position or size of the user's foot.

[0042] Next, when it is desired to change the size of the inner circumference of the holding part main body 22 from the state of the right sandal X in FIG. 7(a), the user releases the fixing of the fixing means F and moves the first holding part constituent 22a and the second holding part constituent 22b to the outside of the right sandal X on the left and right, respectively, when viewed from the front.

[0043] Next, the user uses the fixing means F to fix the first holding part constituent 22a and the second holding part constituent 22b together. By doing so, the size of the inner circumference of the holding part main body 22 of the right sandal X can be changed as shown in FIG. 7(b). In particular, even if the position of the user's foot is different, it is possible to attach the right sandal X to the user's foot. For example, the holding portion 2 can be changed from a state (Figure 7(a)) suitable for holding the user's foot near the toes (toe side) to a state (Figure 7(b)) suitable for holding the user's foot near the ankle.

[0044] Next, when training the trunk and sense of balance using the right sandal X, the user stands while wearing the right sandal X and the left sandal (not shown). By doing so, the convex shape of the bottom of the sole causes the right sandal X and the left sandal (not shown) to swing back and forth when the user stands, making it possible to train the core and sense of balance.

[0045] When taking off the right sandal X that has been worn, the user moves the user's foot toward the heel (rear) side of the right sandal X. At this time, if it is difficult to take off the right sandal X, the user releases the fixing of the fixing means F. In this way, the user can take off the right sandal X.

[0046] <Effects> According to this embodiment, the right sandal X comprises a sole part 1 that contacts the sole of the user's foot and a holding part 2 that holds the user's foot. The holding part 2 is positioned directly above the center of gravity of the sole part 1 and is configured so that the length of the inner circumference can be adjusted. Therefore, even if the position of the user's foot to be held is different, the right sandal X can be put on the user's foot. Furthermore, it is possible to wear the right sandal X regardless of the size of the foot. Furthermore, since the holding part 2 is disposed directly above the center of gravity of the sole part 1, it becomes easy to maintain balance when wearing the sandals.

[0047] Furthermore, the holding portion 2 has erected portions 21 that stand opposite both ends of the sole portion 1 in the front-to-rear direction, and a holding portion main body 22 that extends from the erected portions 21, and the holding portion main body 22 includes a first holding portion component 22a and a second holding portion component 22b, and the length of the inner circumference of the first holding portion component 22a or the second holding portion component 22b can be adjusted by changing the relative position of the first holding portion component 22a or the second holding portion component 22b, so that the opening formed by the holding portion 2 is maintained when no external force is applied, which contributes to improving the breathability of the sole portion 1.

[0048] Furthermore, since the first holding part constituent 22a or the second holding part constituent 22b is provided with fixing means F that can adjust and fix the length of the inner circumference, it becomes possible to maintain the length of the inner circumference of the holding part 2 at an appropriate size.

[0049] In addition, since the bottom surface of the sole part 1 is formed in a downward convex curve when viewed from the side, when the user stands on their own, they need to use their trunk to balance themselves front to back, making it possible to train the trunk and sense of balance.

[0050] Furthermore, since the convex apex of the curve is located directly below the center of gravity of the sole portion 1, it becomes relatively easy for the user to maintain balance when standing on their own.

[0051] Furthermore, since the heel side of the sole portion 1 is shortened, the distance from the end of the sole to the center of gravity of the sandal is shortened, making it relatively easier for the user to balance when standing on their own.

[0052] In addition, the top surface of the sole part 1 is formed in an upwardly convex curve when viewed from the side, which improves the holding performance of the holding part 2 and also relatively widens the opening of the holding part 2, making it easier to put on.

[0053] <Example of change> The shapes and dimensions of the components shown in the above-described embodiment are merely examples and can be modified in various ways based on design requirements, etc.

[0054] For example, the fastening means F may be a buckle pin type belt. This prevents the right sandal X from accidentally falling off when the user makes vigorous movements, compared to a hook-and-loop fastener.

[0055] Also, for example, the fixing means F may be a snap. In addition, a plurality of such snaps may be provided along the width direction. This makes it possible to hold the user's foot more firmly than with a hook-and-loop fastener. Furthermore, since the fixing means F is not formed as an outer shape of the right sandal X, various designs can be applied to the holding part 2.

[0056] Also, for example, the holding part 2 may be formed of one belt, and the fixing means F may be a through-type buckle. [Explanation of symbols]
