[Figure 3] This is a schematic diagram showing a cross-section of the shoe according to this embodiment. [Figure 4] This is an explanatory diagram showing the shoe lining removed from the outer shoe. [Figure 5] This is a perspective view of a shoe interior. Detailed Description of the Invention

[0011] Embodiments for implementing the shoe and the shoe interior body of the present disclosure will be described below based on the drawings.

[0012] As shown in Figures 1 to 3, the shoe 1 of the present embodiment includes an outer shoe 100, and a shoe interior body 200 that is detachably housed in the outer shoe 100. Note that the shoe 1 may be provided with an unillustrated insole disposed between the outer shoe 100 and the shoe interior body 200, or inside the shoe interior body 200. In addition, the shoe 1 forms a pair for left and right feet, and has a bilaterally symmetric structure. Therefore, the following description will be directed to the shoe 1 for the left foot, and the description of the shoe for the right foot will be omitted as it is symmetrical to the shoe 1 for the left foot.

[0013] Further, in the following description, in the shoe 1, the foot length direction is defined as the front-rear direction X, and the foot width direction is defined as the width direction Y. The direction orthogonal to the front-rear direction X and the width direction Y is defined as the up-down direction Z. Furthermore, the circumferential direction of the foot centered on the up-down direction Z is defined as the foot circumferential direction. In the front-rear direction X, the toe side is defined as the front side, and the heel side is defined as the rear side. In the up-down direction Z, the sole side is defined as the lower side, and the shoe opening side is defined as the upper side.

[0014] The outer shoe 100 is a lace-up type high boot laced up with shoelaces 25. As shown in Figure 1 and other drawings, the outer shoe 100 has a sole 10 and an upper 20.

[0015] As shown in Figure 3, the sole 10 is a plate-shaped member having a ground contact surface 11 that contacts the ground and a top surface on the opposite side. The sole 10 is formed of synthetic rubber, foamed polyurethane or the like. The sole 10 is formed with an uneven shape that serves as a non-slip feature on the ground contact surface 11. In addition, the sole 10 may be of multiple layers, or may incorporate a stainless steel plate or the like.

[0016] The upper 20 is provided on the upper (top surface) of the sole 10 and covers part of the wearer's foot, ankle, shin, and calf. The upper 20 is formed by appropriately combining leather materials such as natural leather or synthetic leather, waterproof and breathable materials, etc. The upper 20 has a toe portion 21, a heel portion 22, a waist portion 23, and a tongue portion 24. The upper 20 also has an outer shoe opening 30 (see Figure 4).

[0017] The toe section 21 is the part that covers the wearer's toes. The toe section 21 contains a rigid, cup-shaped toe cap (not shown) with a closed tip. The toe cap is a component that protects the wearer's toes.

[0018] The heel portion 22 is the part that covers the heel of the wearer's foot. The heel portion 22 has a curved heel core (not shown) built into it that wraps around the wearer's heel. The heel core protects the wearer's heel and prevents the heel portion 22 from losing its shape.

[0019] The waist portion 23 is a part that continuously covers the area of ​​the wearer's foot excluding the toes and heels. The waist portion 23 opens to the left and right in the area facing the instep of the wearer's foot. A pair of wings 23c, which are the ends of the waist portion 23 on the instep side, are provided with multiple lace fixing parts 26 for securing the shoelaces 25. The multiple lace fixing parts 26 are arranged at regular intervals along the front-to-back direction X. In addition, the lace fixing parts 26 provided on each wing 23c are positioned opposite each other in the width direction Y, with the tongue portion 24 in between.

[0020] The waist portion 23 has at least the outer surface of the wing 23c made of leather. Basic It is covered with material to increase its rigidity. The lace fixing part 26 only needs to be able to fix the shoelace 25 to the waist part 23. That is, the lace fixing part 26 is composed of, for example, a through hole through which the shoelace 25 can be inserted, an annular member through which the shoelace 25 can be inserted, or a hook material on which the shoelace 25 can be hooked. The shoelace 25 is a lace that fastens a pair of wings 23c together and is tied to prevent the outer shoe 100 from coming off.

[0021] The tongue portion 24 is positioned between the pair of wings 23c and continuously covers part of the wearer's instep and shin. The tongue portion 24 is connected to the toe portion 21 and the pair of wings 23c. The tongue portion 24 has lower rigidity than the toe portion 21, heel portion 22, and waist portion 23. Furthermore, when the shoelaces 25 are tightened and the spacing between the wings 23c in the width direction Y narrows, the tongue portion 24 deforms into a folded state. Conversely, when the shoelaces 25 are loosened and the spacing between the wings 23c in the width direction Y widens, the tongue portion 24 deforms into an open state. In other words, the wings 23c of the waist portion 23 and the tongue portion 24 constitute the instep portion of the upper 20, which covers at least the wearer's instep and whose length in the width direction Y is adjustable.

[0022] The instep area can be adjusted in width by loosening the shoelaces 25. Y The length is adjustable. That is, the instep is held in place by the shoelaces 25 on the upper 20 in the width direction. Y The length is adjusted. Also, the outer shoe 100 expands in the width direction Y as the instep expands, which expands the opening of the outer shoe 30 (see Figure 4).

[0023] Furthermore, the upper end portion 24a of the tongue portion 24 is provided with a hem portion 27 that is more rigid than the tongue portion 24.

[0024] The hem portion 27 is attached to the center of the upper end portion 24a of the tongue portion 24 in the width direction. The hem portion 27 stands upright from the tongue portion 24. The upper end portion 23a of the waist portion 23 and the hem portion 27 have leather outer surfaces. Basic It is covered with material, increasing its rigidity.

[0025] Then, the outer shoe 100 is tightened with shoelaces 25. Ta At this time, the upper end 23a of the waist portion 23 and the hem portion 27 are continuous in the direction of the foot, forming the outer shoe opening 30. At this time, the outer shoe opening 30 becomes narrower compared to when the shoelaces 25 are loosened. Also, the outer shoe 100 is when the shoelaces 25 are loosened. TaAt this time, as shown in Figure 4, the distance between the pair of wings 23c widens, and the hem portion 27 separates from the waist portion 23. Then, the upper end portion 23a of the waist portion 23, the hem portion 27, and the upper end portion 24a of the tongue portion 24 form the outer shoe opening 30. At this time, the outer shoe opening 30 becomes wider than when the shoelaces 25 are tightened.

[0026] Specifically, the rear edge of the outer shoe opening 30 on the heel side is formed by the upper end 23a of the waist portion 23. Also, the front edge of the outer shoe opening 30 on the toe side is formed by the hem portion 27. The outer shoe opening 30 is separable from the upper end 23a of the waist portion 23, which is the rear edge, and the hem portion 27, which is the front edge.

[0027] The shoe lining 200 has a boot shape formed in a bag-like manner. As shown in Figure 5, the shoe lining 200 comprises an inner body 40 and an engaging piece 50.

[0028] The inner body 40 is formed from a fabric that can be freely deformed, and it is preferable that it be formed from, for example, a moisture-absorbing and heat-generating material. That is, the inner body 40 may be formed from a two-layered brushed fabric in which a first brushed knit fabric is placed on the outside and a second brushed knit fabric is placed on the inside. Alternatively, the inner body 40 may be formed from a three-layered brushed fabric in which felt is sandwiched between the first and second brushed knit fabrics. Here, it is preferable that the first brushed knit fabric is made mainly of polyester. It is also preferable that the second brushed knit fabric is made mainly of polyester interwoven with acrylate fibers, or made mainly of polyester. Furthermore, it is preferable that the felt is made using, for example, acrylic fibers. The first and second brushed knit fabrics can be bonded together, for example, by spot bonding of the surface and back surface using an ultrasonic welder.

[0029] The inner body 40 is composed of an inner sole 41 and an inner upper 42.

[0030] The inner sole 41 is the part that comes into contact with the wearer's sole. The inner upper 42 is provided above the inner sole 41 and integrally covers the wearer's foot, ankle, shin, and part of the calf. The inner opening 60 is formed in the inner upper 42.

[0031] Furthermore, the inner upper 42 has two notches 43 that extend downward from the inner opening 60. The periphery of the inner opening 60 is divided by the two notches 43 into a rear portion on the heel side and a front portion on the toe side.

[0032] Furthermore, when the inner body 40 is housed in the outer shoe 100, the bottom edge 43a of the notched portion 43 is at approximately the same height as the upper edge 24b of the tongue portion 24. Therefore, the inner body 40 hardly protrudes from the outer shoe 100.

[0033] The engaging piece 50 is a piece of fabric positioned on the outside of the inner body 40, with at least a portion attached to the inner upper 42. The engaging piece 50 has a two-layer structure of leather and fabric, with the leather facing the outside of the inner body 40. The upper end 50a of the engaging piece 50 is fixed to the periphery of the inner opening 60, that is, to the upper edge 42b of the inner upper 42, and hangs down from the inner opening 60.

[0034] Furthermore, the engaging piece 50 has a rear engaging piece 51 on the heel side and a front engaging piece 53 on the toe side.

[0035] The rear engaging piece 51 extends along the entire length of the rear portion of the inner shoe opening 60. The upper end 50a of the rear engaging piece 51 is fixed to the rear portion of the inner shoe opening 60, and both side edges 51a in the direction of the foot are fixed to the inner body 40 along the notch 43. As a result, a pocket-shaped rear space 52 is formed between the rear engaging piece 51 and the inner body 40, with the upper end 50a and both side edges 51a closed and open downwards.

[0036] Furthermore, a pair of lace fixing parts 55 for securing the shoelace 25 are provided on the outer circumferential surface of the rear engaging piece 51. The lace fixing parts 55 are positioned near both side edges 51a. The lace fixing parts 55 only need to be able to secure the shoelace 25 to the rear engaging piece 51. The lace fixing parts 55 are composed of, for example, through holes through which the shoelace 25 can be inserted, annular members through which the shoelace 25 can be inserted, or hooks that can be used to hook the shoelace 25.

[0037] The front engaging piece 53 extends along the entire length of the front portion of the inner shoe opening 60. The upper end 50a of the front engaging piece 53 is fixed to the front portion of the inner shoe opening 60, and both side edges 53a in the direction of the foot are fixed to the inner body 40 along the notch 43. As a result, a pocket-shaped front space 54 is formed between the front engaging piece 53 and the inner body 40, with the upper end 50a and both side edges 53a closed and open downwards.

[0038] In other words, the rear space 52 and the front space 54 are separated by the notch 43.

[0039] The engaging piece 50 is exposed to the outside of the outer shoe 100 when the inner body 40 is housed in the outer shoe 100, and covers at least a portion of the outer shoe opening 30. Here, the upper end 23a of the waist portion 23, which is the rear edge portion on the heel side of the outer shoe opening 30, is inserted into the rear space 52 and covered by the rear engaging piece 51. Also, the hem portion 27, which is the front edge portion on the toe side of the outer shoe opening 30, is inserted into the front space 54 and covered by the front engaging piece 53.

[0040] The operation of the shoe 1 and shoe lining 200 in this embodiment is described below.

[0041] As shown in Figure 1, etc., before the wearer puts on the shoe 1, the inner body 40 of the shoe lining 200 is pre-installed in the outer shoe 100. With the inner body 40 installed, the upper end 23a of the waist portion 23, which is the rear edge on the heel side, is inserted into the rear space 52 of the outer shoe opening 30. The hem portion 27, which is the front edge on the toe side, is inserted into the front space 54. At this time, the engaging piece 50 is exposed on the outside of the outer upper of the outer shoe 100. The upper end 23a of the waist portion 23 is covered by the rear engaging piece 51. The hem portion 27 is covered by the front engaging piece 53.

[0042] When the inner shoe body 40 is inserted, the shoelaces 25 attached to the outer shoe 100 are loosened, and the instep area is widened. This expands the opening 30 of the outer shoe, making it easy to insert the inner shoe body 40.

[0043] The wearer then puts on the outer shoe 100 via the inner shoe lining 200. Therefore, even if the wearer sweats, the inner shoe lining 200 prevents the outer shoe 100 from getting wet or dirty. Furthermore, the wearer can keep the inside of the outer shoe 100 dry and clean by replacing the inner shoe lining 200 as needed.

[0044] Furthermore, in shoe 1, with the inner body 40 housed in the outer shoe 100, the upper end 23a of the waist portion 23 is covered by the rear engaging piece 51, and the hem portion 27 is covered by the front engaging piece 53. Therefore, the wearer puts on shoe 1 with the engaging piece 50 hooked onto the opening 30 of the outer shoe. In addition, the inside of the outer shoe 100 is covered by the inner body 40, and the structure that fixes the inner body 40 to the outer shoe 100 does not come into contact with the wearer. As a result, shoe 1 can suppress displacement of the shoe lining 200 relative to the outer shoe 100 without causing discomfort to the wearer.

[0045] In addition, in shoe 1, the rear engaging piece 51 and the front engaging piece 53, which constitute the engaging piece 50, are fixed to the upper edge 42b of the inner body upper 42, which is the periphery of the inner body opening 60.

[0046] Therefore, when the inner body 40 of shoe 1 is housed in the outer shoe 100, the inner body 40 is prevented from being exposed from the opening 30 of the outer shoe. As a result, it is difficult to tell from the outside that the shoe 1 has an inner shoe body 200 attached, thus improving its appearance.

[0047] Furthermore, shoe 1 is a long, lace-up boot with an outer shoe 100 secured by shoelaces 25. In other words, the upper 20 of the outer shoe 100 covers at least the wearer's instep, as well as the width direction. Y It has an adjustable instep portion (wingtip 23c and tongue portion 24). The instep portion is held in place by shoelaces 25 which are attached to the upper 20 in the width direction. Y The length is adjusted. The engaging piece 50 of the shoe lining 200 has a lace fixing part 55 that secures the shoelace 25 to the rear engaging piece 51.

[0048] Therefore, the shoe lining 200 is tightened against the outer shoe 100 by the shoelaces 25 being fixed to the lace fixing portion 55 provided on the rear engaging piece 51. As a result, the shoe 1 can further suppress the misalignment of the shoe lining 200 relative to the outer shoe 100.

[0049] Furthermore, in shoe 1, the outer shoe opening 30 has a rear edge portion on the heel side, which is the upper end portion 23a of the waist portion 23, and a front edge portion on the toe side, which is the hem portion 27. In addition, the engaging piece 50 has a rear engaging piece 51 on the heel side and a front engaging piece 53 on the toe side. Here, the rear engaging piece 51 has both side edges 51a fixed to the inner body 40. The rear engaging piece 51 forms a pocket-shaped rear space 52 between itself and the inner body 40, with its upper end portion 50a and both side edges 51a closed and open downwards. The front engaging piece 53 has both side edges 53a fixed to the inner body 40. The front engaging piece 53 forms a pocket-shaped front space 54 between itself and the inner body 40, with its upper end portion 50a and both side edges 53a closed and open downwards.

[0050] Furthermore, in shoe 1, the rear edge of the outer shoe opening 30 (the upper end 23a of the waist portion 23) is inserted into the rear space 52 of the shoe lining 200. Also, the front edge of the outer shoe opening 30 (hem portion 27) is inserted into the front space 54.

[0051] Therefore, when the shoe lining 200 rotates in the direction of the foot, both side edges 51a of the rear engaging piece 51 interfere with the rear edge (upper end portion 23a of the waist portion 23). Also, both side edges 53a of the front engaging piece 53 interfere with the front edge (hem portion 27). As a result, the rotation of the shoe lining 200 relative to the outer shoe 100 is restricted. Consequently, the shoe 1 can suppress the displacement of the shoe lining 200 relative to the outer shoe 100 in the direction of the foot.

[0052] Furthermore, the inner upper 42 has a notch 43 that extends downward from the inner opening 60. The rear space 52 and the front space 54 are separated by the notch 43. As a result, when the shoelaces 25 are loosened and the outer shoe opening 30 is widened, the inner shoe body 200 does not hinder the deformation of the inner body 40 that follows the deformation of the tongue 24. The inner shoe body 200 can also widen the inner opening 60.

[0053] Although embodiments of this disclosure have been described in detail above, this disclosure is not limited to these embodiments. Naturally, the shoes and shoe interiors of this disclosure can be modified within the scope of the technical concept of this disclosure.

[0054] For example, the above example shows an example in which the engaging piece 50 of the shoe lining 200 has a rear engaging piece 51 and a front engaging piece 53. However, the engaging piece 50 only needs to cover at least a part of the outer shoe opening 30. That is, the engaging piece 50 may consist of, for example, only the rear engaging piece 51. In this case, only the rear edge (upper end 23a of the waist portion 23) of the outer shoe opening 30 of the shoe 1 is covered by the engaging piece 50. Alternatively, the engaging piece 50 may consist of only the front engaging piece 53. In this case, only the front edge (hem portion 27) of the outer shoe opening 30 of the shoe 1 is covered by the engaging piece 50. Furthermore, the engaging piece 50 may be provided continuously around the entire circumference of the lining opening 60 in the foot direction. In this case, the entire circumference of the outer shoe opening 30 of the shoe 1 is continuously covered by the engaging piece 50.

[0055] Furthermore, the above example shows that both side edges 51a of the rear engaging piece 51 and both side edges 53a of the front engaging piece 53 are fixed to the inner body 40. However, it is sufficient that at least the upper end 50a of the engaging piece 50 is fixed to the inner body 40. In other words, both side edges 51a of the rear engaging piece 51 and both side edges 53a of the front engaging piece 53 do not need to be fixed to the inner body 40.

[0056] Furthermore, the above example shows a case where it is desirable for the inner body 40 to be made of a moisture-absorbing, heat-generating material. However, the material of the inner body 40 can be arbitrarily selected. Therefore, the inner body 40 may be made of a cooling material. In this case, it is possible to reduce the heat felt by the wearer. In addition, the inner body 40 may be made of a material having antibacterial and deodorizing properties. Furthermore, the inner body 40 may have a conductive structure (not shown).

[0057] Furthermore, the above example shows the outer shoe 100 as a lace-up type long boot. However, the outer shoe 100 may also be a short shoe with the upper 20 reaching to the wearer's ankle. In addition, the outer shoe 100 may define the length of the instep in the width direction Y using hook-and-loop fasteners or the like. Moreover, the outer shoe 100 may also be a slip-on type or a boot type in which the length of the instep in the width direction Y does not change.

[0058] Furthermore, the above example shows that the engaging piece 50 is fixed to the periphery of the inner lining opening 60 (the upper edge 42b of the inner lining upper 42). However, the engaging piece 50 may also be fixed closer to the inner lining sole 41 than to the periphery of the inner lining opening 60. In other words, the engaging piece 50 may be fixed to the outer circumferential surface of the tubular portion of the inner lining upper 42 that covers the shin. In this case, when the inner body 40 of the shoe lining 200 is housed in the outer shoe 100, a part of the inner lining upper 42 protrudes from the outer shoe opening 30. The shoe 1 can then prevent water, snow, etc. from entering the inner lining upper 42 by, for example, contracting the inner lining opening 60 with rubber, while the engaging piece 50 prevents water, etc. from entering the upper 20 from the outer shoe opening 30.
