Problems to be Solved by the Invention

[0006] The purpose of this disclosure is to provide a shoe and a shoe interior that can suppress displacement of the shoe interior relative to the outer shoe without causing discomfort to the wearer. [Means for solving the problem]

[0007] To achieve the above objective, the shoe of the present disclosure is a shoe comprising an outer shoe having a sole and an upper provided on the upper side of the sole and having an outer shoe opening formed thereon, and an inner shoe body detachably housed in the outer shoe, wherein the inner shoe body comprises an inner body composed of an inner sole and an inner upper provided on the upper side of the inner sole and having an inner shoe opening formed thereon, and an engaging piece disposed on the outside of the inner body, with its upper end fixed and hanging downward, wherein the engaging piece covers at least a portion of the outer shoe opening when the inner body is housed in the outer shoe.

[0008] Furthermore, the shoe interior of the present disclosure comprises an inner body having an interior sole and an interior upper provided on the upper side of the interior sole and having an interior opening formed thereon, and is a shoe interior that is removablely housed in an outer shoe, and is provided with an engaging piece disposed on the outside of the inner body, with its upper end fixed and hanging downward, wherein the engaging piece covers at least a part of the opening of the outer shoe when the inner body is housed in the outer shoe. [Effects of the Invention]

[0009] As a result, the shoes and shoe linings of this disclosure can suppress misalignment of the shoe lining relative to the outer shoe without causing discomfort to the wearer. [Brief explanation of the drawing]

[0010] [Figure 1] This is a perspective view of the shoe according to this embodiment. [Figure 2] This is a front view of the shoe according to this embodiment. [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. [Modes for carrying out the invention]

[0011] Embodiments for implementing the shoes and shoe linings of this disclosure are described below with reference to the drawings.

[0012] As shown in Figures 1 to 3, the shoe 1 of this embodiment comprises an outer shoe 100 and a shoe interior 200 that is detachably housed in the outer shoe 100. An insole (not shown) may be placed between the outer shoe 100 and the shoe interior 200, or inside the shoe interior 200. The shoe 1 is a set of left and right shoes, but has a symmetrical structure. Therefore, the following description will focus on the left shoe 1, and the description of the right shoe will be omitted as it is symmetrical to the left shoe 1.

[0013] Furthermore, in the following explanation, in shoe 1, the length direction of the foot is defined as the front-to-back direction X, and the width direction of the foot is defined as the width direction Y. Also, the direction perpendicular to the front-to-back direction X and the width direction Y is defined as the up-to-down direction Z. In addition, the circumferential direction of the foot centered on the up-to-down direction Z is defined as the foot circumference direction. And in the front-to-back direction X, the toe side is considered forward and the heel side is considered backward. Furthermore, in the up-to-down direction Z, the sole side is considered downward and the opening side is considered upward.

[0014] The outer shoe 100 is a long upper shoe of the knitting type with a shoelace 25. As shown in FIG. 1 etc., the outer shoe 100 has a shoe sole 10 and a vamp 20.

[0015] As shown in FIG. 3, the shoe sole 10 is a plate-like member having a ground contact surface 11 that contacts the ground and an opposite top surface. The shoe sole 10 is formed of synthetic rubber, foamed polyurethane, or the like. The shoe sole 10 has an uneven shape that provides anti-slip on the ground contact surface 11. Also, the shoe sole 10 may be multiple layers or may incorporate a stainless steel plate or the like.

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

[0017] The toe part 21 is a part that covers the toe of the wearer's foot. A cup-shaped hard toe core (not shown) with a closed tip is incorporated in the toe part 21. The toe core is a member that protects the wearer's toe.

[0018] The heel part 22 is a part that covers the heel of the wearer's foot. A heel core (not shown) curved in a shape that wraps around the wearer's heel is incorporated in the heel part 22. The heel core is a member that protects the wearer's heel and prevents the heel part 22 from losing its shape.

[0019] The waist part 23 is a part that continuously covers the area excluding the toe and heel of the wearer's foot. The waist part 23 has an area facing the instep of the wearer's foot open to the left and right. And a plurality of string fixing parts 26 for fixing the shoelace 25 are provided on a pair of wings 23c that are the instep-side ends of the waist part 23. The plurality of string fixing parts 26 are arranged at regular intervals along the front-rear direction X. Also, the string fixing parts 26 provided on each wing 23c are arranged at positions facing each other in the width direction Y with the throat part 24 interposed therebetween.

[0020] The waist part 23 is such that at least the outer surface of the blade 23c is covered with a leather material and its rigidity is enhanced. Also, the string fixing part 26 only needs to be able to fix the shoe string 25 to the waist part 23. That is, the string fixing part 26 is constituted by, for example, a through-hole through which the shoe string 25 can be inserted, an annular member through which the shoe string 25 can be inserted, a hook material that can hook the shoe string 25, and the like. The shoe string 25 is a string that binds the pair of blades 23c together so that the outer shoe 100 cannot be taken off.

[0021] The vamp part 24 is arranged between the pair of blades 23c and is a part that continuously covers a part of the wearer's instep and shin. The vamp part 24 is connected to the toe part 21 and the pair of blades 23c. And the vamp part 24 has a lower rigidity than each of the toe part 21, the heel part 22, and the waist part 23. Further, when the shoe string 25 is tightened and the interval in the width direction Y of the blade 23c becomes narrow, the vamp part 24 is deformed into a folded state. Also, when the shoe string 25 is loosened and the interval in the width direction Y of the blade 23c becomes wide, the vamp part 24 is deformed into a widened state. That is, the blade 23c of the waist part 23 and the vamp part so at least cover the wearer's instep and constitute the instep part of the instep covering 20 whose length in the width direction Y can be adjusted.

[0022] The length of the instep part in the width direction W can be changed by loosening the shoe string 25. That is, the length of the instep part in the width direction W is adjusted by the shoe string 25 held by the instep covering 20. Also, when the instep part expands in the width direction Y, the wearing opening 30 of the outer shoe 100 expands (see FIG. 4).

[0023] Furthermore, a hem part 27 having a higher rigidity than the vamp part 24 is provided at the upper end part 24a of the vamp part 24.

[0024] The hem part 27 is attached to the central part in the width direction of the upper end part 24a of the vamp part 24. And the hem part 27 stands upright upward from the vamp part 24. Also, the outer surfaces of the upper end part 23a of the waist part 23 and the hem part 27 are covered with a leather material and their rigidities are enhanced.

[0025] When the shoelaces 25 are tightened, the upper end 23a of the waist portion 23 and the hem portion 27 of the outer shoe 100 are continuous in the direction of the foot, forming the outer shoe opening 30. At this time, the outer shoe opening 30 is narrower than when the shoelaces 25 are loosened. Also, when the shoelaces 25 are loosened, 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. The upper end 23a of the waist portion 23, the hem portion 27, and the upper end 24a of the tongue portion 24 form the outer shoe opening 30. At this time, the outer shoe opening 30 is 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 lace-up type long boot with an outer shoe 100 secured by shoelaces 25. That is, the upper 20 of the outer shoe 100 covers at least the wearer's instep and has an instep portion (wingtip 23c and tongue portion 24) whose length in the width direction W is adjustable. The length of the instep portion in the width direction W is adjusted by the shoelaces 25 held in place by the upper 20. The engaging piece 50 of the shoe inner body 200 has a lace fixing part 55 that secures the shoelaces 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. 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.
