Description

[Technical field]

[0001] The present disclosure relates to footwear, particularly short boots. [Background technology]

[0002] Japanese Patent Laid-Open No. 2022-139151 (Patent Document 1) describes footwear having a heel part at the rear end of the upper, in which a hard protrusion part extending upward and diagonally backward is formed at the upper end of the heel part. In this conventional example of footwear, the protrusion part guides the heel of the foot into the footwear, so that the footwear can be put on correctly without using hands or a shoe horn.

[0003] However, for example, people with weak muscles (children, elderly people, etc.) or people with diseases or disabilities in some parts of the legs (for example, knees, etc.) tend to have their feet fall onto the inside (arch side) of both feet when trying to put on footwear. This is because when standing, the center line of the body is the center of gravity, and when stepping on the ground to put on shoes, the weight is shifted to the center line of the body, making it easier to lean towards the inside (arch side) of the foot. For this reason, when trying to put on such footwear, there is no action to support the heel of the footwear by adjusting the angle slightly inward, as when using a hand or a shoe horn, and the arch side of the footwear is easily crushed by the foot. In addition, similar inconveniences can occur not only in people with weak muscles, etc., so it is believed that if the above-mentioned inconveniences could be eliminated, footwear that is easy for everyone to wear could be realized.

[Diagram 2] FIG. 2(A) is a plan view of the footwear of the embodiment, and FIG. 2(B) is a rear view of the footwear of the embodiment. [Diagram 3] FIG. 3 is a perspective view of the inner part 13 as viewed from the right side. [Figure 4] FIG. 4 is a plan view of the inner portion 13 as viewed from above. [Diagram 5] FIG. 5 is a diagram showing a schematic diagram of the slope shape of the upper end portion of the inner portion 13. As shown in FIG. [Figure 6] FIG. 6 is a diagram showing a schematic diagram of the positional relationship between the ankle of the left foot and the inner part 13. As shown in FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, footwear (shoes) according to an embodiment will be described with reference to the drawings. Note that the following description will be directed to footwear for the left foot. Detailed description of footwear for the right foot will be omitted since it has a symmetrical structure to the footwear for the left foot described below.

[0010] Fig. 1(A) is a left side view of the footwear of one embodiment, Fig. 1(B) is a right side view of the footwear of one embodiment, Fig. 2(A) is a plan view of the footwear of one embodiment, and Fig. 2(B) is a rear view of the footwear of one embodiment.

[0011] The footwear of this embodiment shown in each drawing includes a sole portion 11 and a main portion 10 provided thereon. The main portion 10 has a total length L of, for example, about 20 to 30 cm according to the size of the foot, and is configured to cover the entire foot of the wearer (i.e., the toes, instep, sides of the foot, etc.). The main portion 10 has an opening 10a at the rear end for inserting the foot. The sole portion 11 is provided at the lower portion of the main portion 10. The sole portion 11 is a portion for supporting the sole of the foot.

[0012] The main body 10 has a protrusion 12 at the top of the rear end side. The protrusion 12 protrudes rearward and diagonally upward from the main body 10. This protrusion 12 is a part for allowing the heel to be smoothly inserted without using hands or a shoehorn when putting the left foot into the footwear. For this reason, the protrusion 12 and the heel part 12a as a part of the main body 10 that supports the protrusion 12 have a certain degree of hardness so that the shape is not easily distorted when the heel of the foot is inserted. The protrusion 12 is a part that comes into contact with the heel of the wearer's foot during the putting-on action, and serves to facilitate the heel sliding into the inside of the footwear.

[0013] The main body 10 is provided with inner parts 13 arranged from the heel portion 12a to the left and right sides so as to extend to the front of the main body 10. The inner parts 13 are formed, for example, using a core material arranged inside the inner cloth covering the inside of the main body 10 and a flexible cushioning material arranged around the core material, and are arranged inside the main body 10. In each drawing, a pattern is added to show the range in which the inner parts 13 are arranged so as to make it easier to understand.

[0014] Fig. 3 is a perspective view of the inner part 13 as viewed from the right side, and Fig. 4 is a plan view of the inner part 13 as viewed from above. Here, the state in which only the inner part 13 is extracted from the main body part 10 is shown. The inner part 13 has a protruding part 20, a first side part 21, a second side part 22, and a rear end part 23. The inner part 13 is made of a material (soft elastic material) having a certain degree of flexibility, and can flexibly contract to a certain degree according to the shape of the left foot when the left foot is placed inside the footwear (i.e., when the footwear is worn).

[0015] The protrusion 20 is a portion that corresponds to the protrusion 12 of the main body 10 described above, and protrudes rearward and obliquely upward from the main body 10, similar to the protrusion 12. The protrusion 20 is disposed inside the protrusion 12 of the main body 10. The upper end position of the protrusion 20 is substantially equal to the upper end position of the protrusion 10 (see FIG. 1(A) etc.).

[0016] The first side portion 21 is a portion of the main body portion 10 that is disposed on the arch side of the left foot. The second side portion 22 is a portion of the main body portion 10 that is disposed on the opposite side to the arch side of the left foot.

[0017] The rear end portion 23 is a portion that is disposed on the rear end side of the main body portion 10. The rear end portion 23 is configured to bulge out toward the rear of the main body portion 10 so as to encase the heel of the left foot.

[0018] The first side portion 21, the second side portion 22, and the rear end portion 23 are integrally formed as shown in the figure, and are configured to be generally J-shaped in plan view as a whole (see FIG. 4). The first side portion 21 is a portion that contacts the side surface of the arch side of the left foot and supports said side surface. The second side portion 22 is a portion that contacts the side surface opposite the arch side of the left foot and supports said side surface. The rear end portion 23 is a portion that contacts the heel of the left foot and supports the heel. As shown in the above-mentioned FIG. 3 and FIG. 4, the first side portion 21, the second side portion 22, and the rear end portion 23 have a certain degree of thickness and are configured to bulge toward the inside of the footwear.

[0019] The length L1 of the first side portion 21 (see FIG. 2(A)) is configured to be about 1 / 3 of the total length L of the main body portion 10. More specifically, the length L1 of the first side portion 21 is preferably configured to be 30% to 40% (0.3L≦L1≦0.4L) of the total length L of the main body portion 10. This allows the first side portion 21 to support the portion of the foot skeleton from the calcaneus to the metatarsal (first metatarsal), providing more support for the arch side where the left foot tends to collapse, thereby making it easier to insert the foot.

[0020] The second side portion 22 is configured so that its length L2 (see FIG. 2(A)) is about 1 / 4 of the total length L of the main body portion 10. More specifically, the length L2 of the second side portion 22 is preferably configured to be 20% to 25% of the total length L of the main body portion 10 (0.2L≦L2≦0.25L). This improves the hold from the heel to the arch side and the opposite side, and allows the left foot to be inserted smoothly.

[0021] As shown in FIG. 1(B) and FIG. 3, the first side portion 21 is configured to have a slope shape in which the height of the upper end portion gradually decreases from the protruding portion 10 toward the position where the sole portion 11 is present. In this embodiment, the upper end portion of the first side portion 21 is configured to have a first portion 21a in which the degree of change in the distance from the sole portion 11 is relatively small, and a second portion 21b in which the degree of change in the distance from the sole portion 11 is relatively large. FIG. 5(A) is a diagram showing a schematic diagram of the slope shape of each upper end portion of the first portion 21a and the second portion 21b. In the example shown in FIG. 5(A), the boundary between the first portion 21a and the second portion 21b and the boundary between the first portion 21a and the protruding portion 20 are each shown by dotted lines for ease of understanding.

[0022] The degree of change in distance here refers to the magnitude of change in distance (change in length on the Y-axis in FIG. 5(A) etc.) between the upper end portion and the sole portion 11 per unit distance on the longitudinal axis of the main body portion 10 (X-axis in FIG. 5(A) etc.), where a small amount of change corresponds to a "small degree of change" and a large amount of change corresponds to a "large degree of change." In the example shown in FIG. 5(A), the curve showing the outline of the upper end portion of the first portion 21a has a gentler (gentler) inclination with respect to the X-axis as it moves to the left in the figure (i.e., forward of the main body portion 10), while the curve showing the outline of the upper end portion of the second portion 21b has a steeper inclination with respect to the X-axis as it moves to the left in the figure (i.e., forward of the main body portion 10).

[0023] In this way, by configuring the upper end portion of first side portion 21 so that the height gradually decreases from protrusion 10 toward sole portion 11, it is possible to ensure the function of suppressing deformation of main body portion 10 caused by the heel of the left foot when inserting the left foot to put on the footwear, and also to allow the arch of the left foot to smoothly enter inside main body portion 10 without being hindered much by first side portion 21. Furthermore, as a result of smoother insertion of the left foot, it is also possible to obtain the effect of making the height of protrusion 12 lower.

[0024] In particular, by providing the first portion 21a, in which the degree of change in distance from the sole portion 11 is relatively small, and the second portion 21b, in which the degree of change in distance from the sole portion 11 is relatively large, the first portion 21a can provide more support to the arch side when the left foot begins to be inserted into the main body portion 10, and after the left foot has entered the main body portion 10 to a certain extent, the contact area of ​​the second portion 21b with the arch side is reduced, so that the movement of the left foot into the main body portion 10 is not hindered. Therefore, the insertion of the left foot into the main body portion 10, i.e., the action of putting on footwear, becomes smoother. In addition, the height of the protruding portion 12 can be lowered accordingly, so that the degree of freedom in designing the protruding portion above the heel of footwear that does not require the use of hands or a shoehorn can be increased.

[0025] In addition, by using the first portion 21a and the second portion 21b shown in FIG. 5(A), as shown in the schematic diagram of FIG. 6, when the left foot 30 is inserted into the main body portion 10, it is easy to ensure the size of each of the first portion 21a and the second portion 21b necessary and sufficient for smooth insertion of the left foot while preventing discomfort caused by the inner portion 13 hitting the ankle 31 of the left foot 30. As shown by the dotted line in FIG. 6, the height of the upper end portion of the inner portion 13 can be appropriately set according to the function and design of the footwear. As shown by the dotted line in FIG. 5(B), the slope shape of the upper end portion of the first side portion 21 may be a curved shape such as a circular arc. In this case, the slope shape of the upper end portion is a curved shape that is convex upward in the illustrated example, but the slope shape of the upper end portion may be a curved shape that is convex downward. In addition, the upper end portion of the first side portion 21 may change to a straight line as shown by the example in FIG. 5(C). On the other hand, the upper end portion of the first side portion 21 may be configured to have three or more portions. That is, as long as the height of the upper end portion of the first side portion 21 gradually decreases toward the sole portion 11, the slope shape may be any shape.

[0026] 1(A) and 4, the second side portion 22 has an upper end portion configured to have a slope shape in which the height gradually decreases from the protrusion 10 toward the sole portion 11. In this embodiment, the upper end portion of the second side portion 22 is configured to have a first portion 22a in which the change in distance from the sole portion 11 is relatively small, and a second portion 22b in which the change in distance from the sole portion 11 is relatively large. In other words, the first portion 22a has a relatively small inclination with respect to the sole portion 11, and the second portion 22b has a relatively large inclination with respect to the sole portion 11.

[0027] In this way, by configuring the upper end portion of the second side portion 22 so that it gradually decreases in height from the protrusion portion 10 toward the sole portion 11, it is possible to ensure the function of suppressing deformation of the main body portion 10 caused by the heel of the left foot when the left foot is inserted to put on the footwear, and it is possible for the portion of the left foot opposite the arch to smoothly enter the inside of the main body portion 10 without being obstructed significantly by the first side portion 21.

[0028] The upper end portion of the second side portion 22 does not necessarily have to be configured to have two portions as described above, and the upper end portion of the second side portion 22 may change linearly. On the other hand, the upper end portion of the second side portion 22 may be configured to have three or more portions. In other words, it is sufficient that the height of the upper end portion of the second side portion 22 gradually decreases toward the sole portion 11.

[0029] According to the above-described embodiment, footwear that is easy to wear for anyone can be provided.

[0030] The present disclosure is not limited to the above-described embodiment, and various modifications can be made within the scope of the present disclosure. For example, the above-described embodiment illustrates footwear having a main body 10 that does not use laces, but the scope of application of the present disclosure is not limited to this, and can be applied to footwear having a main body that uses laces (so-called lace-up shoes) and other types of footwear having main bodies. In the above-described embodiment, the inner part 13 has the first side part 21 and the second side part 22, but the second side part 22 may be omitted and the inner part 13 may have the first side part 21 and the rear end part 23.
