Problems to be Solved by the Invention

[0004] <​​​​​​​​​

[0006] The footwear according to the present invention is a footwear having a sole member having a transparent or translucent side wall portion that extends circumferentially, and comprises a sheet-like decorative member arranged along the inner circumferential surface of the side wall portion and having a decorative surface that abuts against the inner circumferential surface of the side wall portion, and a retaining member formed in the shape of a ring that extends in a band shape along the inner circumferential surface of the side wall portion, and which holds the decorative member by sandwiching it between itself and the side wall portion while in surface contact with the decorative member.

[0007] Thus, in the sole of the footwear described above, the decorative member is held between a transparent or translucent side wall and a retaining member, and the decorative surface of the decorative member is visible from the outside through the side wall. Therefore, the decorative surface is protected by the side wall while the side of the sole can be decorated with the decorative surface. Moreover, the ring-shaped retaining member extending along the inner circumference of the decorative member can properly hold even thin and unstable decorative members. Therefore, adhesive is not required to fix the decorative member to the side wall, and the decorative surface of the decorative member is not soiled with unnecessary adhesive. Furthermore, several steps, such as the bonding process for decorative components and the coating process for protective films, are unnecessary. In other words, with the above configuration, it becomes possible to protect the decorative surface that decorates the side of the bottom component in an aesthetically pleasing and simple manner without staining it with adhesive.

[0008] In this case, the sole of the footwear is intermittently subjected to vertical impact loads during use, and therefore the decorative and retaining members are also continuously subjected to vibrations associated with the load. Consequently, even with continuous use of the footwear, it is necessary to securely hold the decorative members in place with the retaining members. In contrast, with the above configuration, the retaining member, which extends in a band shape along the inner circumferential surface of the side wall, is inherently a horizontally elongated shape that is weak against vertical external forces. However, because it has a cylindrical ring structure that curves along the side wall and extends vertically, it is less likely to bend even when subjected to vertical vibrations. Furthermore, since the retaining member is in surface contact with the decorative member, it is less likely to shift vertically along the decorative member. Therefore, even if vibrations are continuously applied during use, the retaining member can maintain surface contact with the decorative member and reliably hold the decorative member.

[0009] Furthermore, it is preferable that the retaining member is made of a sheet material. As described above, even if the retaining member is made of a relatively thin sheet material, it is less likely to bend due to vertical vibrations, and the surface contact state with the decorative member is appropriately maintained, so that the decorative member can be held appropriately even with a relatively thin retaining member.

[0010] Furthermore, it is preferable that the retaining member is elastic and configured to bias the decorative member toward the side wall by the elastic force of the retaining member. This makes it possible to hold the decorative member more securely by the elastic force of the retaining member.

[0011] Furthermore, it is preferable that the bottom member includes a lid portion joined to the upper end of the side wall portion, and that a protruding ridge portion is formed on the lower surface of the lid portion, extending along the inner circumferential surface of the side wall portion, and that the protruding ridge portion is configured to hold the retaining member and the decorative member between itself and the side wall portion. As a result, the retaining member that holds the decorative member is further held by the protruding part, making it possible to hold the decorative member more securely.

[0012] Furthermore, the bottom member comprises a bottom body which is a housing composed of a side wall portion, a bottom plate portion located below the side wall portion, and a lid portion located above the side wall portion, and a light source and a power supply that supplies current to the light source are housed inside the bottom body, and the bottom body may be configured to light up to the side by having at least the side wall portion of the bottom body act as a light guide.

[0013] According to the above configuration, the base of the bottom component is a housing, and the light source and power supply are housed within its internal space. The light from the light source is guided at least to the side walls, allowing the base component to be illuminated laterally. Furthermore, since the components of the base component are used as light guides, there is no need to prepare a separate light guide.

[0014] Furthermore, the footwear according to the present invention is a footwear having a sole member having a transparent or translucent side wall portion that extends circumferentially, and includes a decorative member formed in the shape of a ring that extends in a band-like manner along the inner circumferential surface of the side wall portion, the outer surface that abuts against the inner circumferential surface of the side wall portion being a decorative surface, and the decorative member is configured to maintain a state in which the outer surface of the decorative member is in surface contact with the inner circumferential surface of the side wall portion.

[0015] According to the above configuration, the decorative member maintains a state in which its outer surface is in surface contact with the inner surface of the side wall. Therefore, no adhesive is required to fix the decorative member to the side wall, and the decorative surface is not soiled with unnecessary adhesive. Thus, this configuration also makes it possible to protect the decorative surface easily without soiling it with adhesive.

[0016] Here, the sole of the footwear is intermittently subjected to vertical impact loads during use, and the decorative member is also continuously subjected to vibrations associated with the load. In contrast, the decorative member, which extends in a band shape along the inner circumferential surface of the side wall, is inherently weak against vertical external forces due to its elongated shape. However, because it has a cylindrical ring structure that curves along the side wall and extends vertically, it is less likely to bend even when subjected to vertical vibrations. Furthermore, since the decorative member is in surface contact with the inner circumferential surface of the side wall, it is less likely to shift vertically along the inner circumferential surface of the side wall. Therefore, even when the decorative member is continuously subjected to vibrations during use, it can maintain its surface contact with the inner circumferential surface of the side wall.

[0017] Furthermore, the present invention relates to a method for manufacturing footwear, comprising the steps of: arranging a sheet-like decorative member having a decorative surface along the inner circumferential surface of the side wall and bringing the decorative surface into contact with the inner circumferential surface of the side wall; and holding the decorative member between a ring-shaped retaining member extending along the inner circumferential surface of the side wall and the side wall.

[0018] In this way, the decorative member is held in place by being sandwiched between the ring-shaped retaining member and the side wall, eliminating the need for an adhesive bonding process to fix the decorative member to the side wall. Furthermore, the coating process of a protective film to protect the decorative surface, as in conventional methods, is also eliminated. Therefore, the number of processes is reduced, and the decorative surface can be protected easily without being contaminated with adhesive. [Effects of the Invention]

[0019] According to the present invention, it is possible to provide footwear and a method for manufacturing the same that can easily protect the decorative surface that decorates the side of the sole member without soiling it with adhesive. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0021] Hereinafter, embodiments of the present invention will be described in detail based on the drawings. Note that the present invention is not limited to the following embodiments. 《Embodiment 1》

[0022] Figure 1 is a perspective view showing the external appearance of the zori sandal 1 in this embodiment 1. Figure 2 is a perspective view of the sole body 10 that constitutes the sole member 3. In this embodiment 1, the zori sandal 1 is given as an example of footwear for explanation. However, the footwear in the present invention may be other than the zori sandal 1, such as slippers, sandals, geta (wooden clogs), shoes, or other footwear having a sole member 3.

[0023] As shown in Figures 1 and 2, the sandal 1 comprises a sole member 3 and an upper member 6, a thong 7, and a toe strap 8, which are attached to the upper part 5 on top of the sole member 3. The upper member 6 is the part on which the user's foot rests, and the thong 7 and toe strap 8 are attached to it.

[0024] The bottom member 3 has a bottom body 10 to which the top member 6 is joined on the upper side, and a sole portion 11 to which the bottom body 10 is joined on the lower side. Here, Figure 3 is a perspective view showing the side wall portion 12 and the bottom plate portion 13, and Figure 4 is a bottom view showing the lid portion 14. Figure 5 is a plan view showing the side wall portion 12 and the bottom plate portion 13.

[0025] As shown in Figures 3 to 5, the base body 10 is composed of a circumferentially extending side wall portion 12, a bottom plate portion 13 positioned below the side wall portion 12, and a lid portion 14 positioned above the side wall portion 12, forming an overall enclosure. The inside of the base body 10 is hollow.

[0026] As shown in Figure 5, the sole plate portion 13 has an oval shape. That is, the sole plate portion 13 has a toe-side portion 13a and a heel-side portion 13b, whose outer edges are formed in an arc shape, and straight side portions 13c and 13d connecting them.

[0027] The bottom plate portion 13 is formed integrally with the side wall portion 12 so as to close the lower part of the side wall portion 12. As shown in Figure 5, the side wall portion 12 extends along the outer circumference of the bottom plate portion 13. Therefore, the side wall portion 12 has a curved toe-side portion 12a and a heel-side portion 12b, and substantially flat side portions 12c and 12d connecting them. As a result, the upper edge portion of the side wall portion 12 is oval-shaped. Furthermore, the side wall portion 12 constitutes the side surface of the bottom member 3 along its entire circumference.

[0028] As shown in Figures 2 and 4, the lid portion 14 is a plate-shaped member formed separately from the side wall portion 12 and is joined to the side wall portion 12 so as to close the upper part of the side wall portion 12. The lid portion 14 has an oval outer edge, similar to the upper edge portion of the side wall portion 12. That is, the lid portion 14 has a toe-side portion 14a and a heel-side portion 14b, whose outer edges are formed in an arc shape, and straight side portions 14c and 14d connecting them.

[0029] The side walls 12, bottom plate 13, and lid 14 are formed from a transparent synthetic resin material such as polycarbonate. The side walls 12, bottom plate 13, and lid 14 may also be made from other transparent or translucent materials. For example, materials other than polycarbonate, such as acrylic, can be used. However, polycarbonate is preferred because it is more rigid. Here, "transparent" includes both colorless and colored transparent materials.

[0030] As shown in Figures 3 and 5, a first through-hole 21 is formed on the toe side of the bottom plate portion 13 through which the front thong 8 is inserted, and two second through-holes 22 are formed on the heel side of the bottom plate portion 13 through which the rear end of the thong 7 is inserted. The two second through-holes 22 are arranged side by side at a predetermined interval in the width direction of the sandal 1.

[0031] On the other hand, as shown in Figures 2 and 4, a first opening 31 opposite the first through hole 21 is formed on the toe side of the lid portion 14, and a second opening 32 opposite the second through hole 22 is formed on the heel side of the lid portion 14. The first opening 31 is larger than the first through hole 21. The second opening 32 has an oval shape that extends in the width direction of the sandal 1.

[0032] Here, Figure 6 is a perspective view showing the decorative member 23, and Figure 7 is a perspective view showing the retaining member 25. Figure 8 shows a magnified view of the joint 25a of the retaining member 25, and Figure 9 shows a magnified view of the joint 23a of the decorative member 23. Figure 10 is a magnified longitudinal cross-sectional view showing a part of the bottom body 10.

[0033] For example, as shown in Figures 3 and 10, the bottom member 3 has a sheet-like decorative member 23. The decorative member 23 is arranged along the inner circumferential surface 12e of the side wall portion 12 of the bottom body 10. The decorative member 23 can be made of, for example, woven fabric, cloth, or a synthetic resin sheet.

[0034] As shown in Figure 6, the decorative member 23 is formed in a ring shape by joining both ends of a strip-shaped sheet material at a joint 23a. The joint 23a of the decorative member 23 can be formed by stitching or other joining methods that do not use adhesive. The joint 23a is located, for example, on the toe-side portion 12a of the side wall portion 12.

[0035] The outer circumferential surface of the decorative member 23 is a decorative surface 24. The decorative surface 24 is decorated by, for example, embroidery, weaving, or printing. As shown in Figure 10, the decorative surface 24 is positioned to abut against the inner circumferential surface 12e of the side wall portion 12.

[0036] For example, as shown in Figures 3 and 10, the bottom member 3 further includes a retaining member 25 for holding the decorative member 23. The retaining member 25 is formed in a ring shape that extends in a band-like manner along the inner circumferential surface of the side wall portion 12, and is configured to hold the decorative member 23 by sandwiching it between the retaining member 25 and the side wall portion 12 while in surface contact with the decorative member 23.

[0037] As shown in Figure 7, the retaining member 25 is made of sheet material. For example, the retaining member 25 is formed in a ring shape by joining both ends of a strip-shaped sheet material at a joint 25a. The joint 25a of the retaining member 25 is formed without the use of adhesive, for example, by attaching adhesive tape 26 with both ends of the sheet material butted together. The joint 25a is located on one side portion 12d of the side wall portion 12. The joint 25a of the retaining member 25 is located in a different position from the joint 23a of the decorative member 23.

[0038] The retaining member 25 has substantially the same shape as the decorative member 23, but its outer shape is slightly smaller than that of the decorative member 23. In other words, the retaining member 25 has dimensions and a shape such that its outer peripheral surface 25b is in close contact with the entire circumference of the inner peripheral surface 23b of the decorative member 23, thereby enabling it to hold the decorative member 23 between itself and the side wall portion 12.

[0039] The retaining member 25 can be made of, for example, a synthetic resin sheet such as PET. The retaining member 25 is elastic, and is configured to bias the decorative member 23 toward the side wall portion 12 by the elastic force of the retaining member 25. The retaining member 25 has greater elasticity than the decorative member 23.

[0040] As shown in Figure 10, the retaining member 25 is held by a protruding ridge 16 formed on the lid portion 14. The protruding ridge 16 is formed to protrude from the lower surface of the lid portion 14. As shown in Figures 2 and 4, the protruding ridge 16 is positioned on the toe side portion 14a, the heel side portion 14b, and both side portions 14c, 14d of the lid portion 14, and extends along the inner circumferential surface 12e of the side wall portion 12, respectively.

[0041] As shown in Figure 10, the protruding portion 16 is configured to hold the upper portion of the retaining member 25 and the decorative member 23 by sandwiching them between it and the side wall portion 12. The protruding portion 16 is positioned to support at least a portion of the inner circumferential surface 25c of the retaining member 25.

[0042] Here, Figure 11 is a bottom view showing the bottom member 3. As shown in Figures 1 and 11, the bottom surface of the bottom member 3 is composed of a sole portion 11. The sole portion 11 is formed of a synthetic resin material such as EVA.

[0043] For example, as shown in Figure 3, the bottom plate portion 13 of the bottom body 10 has a first recess 33 and a second recess 34 formed on the back surface, which is the side facing the sole portion 11. A first through hole 21 is formed at the bottom of the first recess 33, and two second through holes 22 are formed at the bottom of the second recess 34.

[0044] As shown in Figure 11, the tip 8a of the front cushion 8, which penetrates the top member 6 and extends through the first through-hole 21 of the bottom body 10, is positioned in the first recess 33. The tip 8a of the front cushion 8 is housed in the first recess 33 together with the locking device 37, while being locked and fixed in place by the locking device 37.

[0045] Meanwhile, the two rear ends 7a of the thong 7, which penetrate the top member 6 and extend through the second through hole 22 of the bottom body 10, are positioned in the second recess 34. Each of the two rear ends 7a of the thong 7 is provided with a hook-and-loop fastener and is housed in the second recess 34 in a state where it is attached and joined to one another.

[0046] The sole portion 11 has a first tongue piece 11a positioned opposite the first recess 33 and a second tongue piece 11b positioned opposite the second recess 34. The first tongue piece 11a is configured to open and close the first recess 33, and the second tongue piece 11b is configured to open and close the second recess 34. This allows the length of the thong 7 and the front strap 8 to be adjusted to improve comfort.

[0047] In manufacturing the sandals 1 according to this embodiment 1, the process involves manufacturing the bottom member 3 and attaching the upper part 5 to the bottom member 3. In the process of manufacturing the bottom member 3, the sole part 11 is attached to the bottom body 10 to manufacture the bottom member 3. In the process of attaching the upper part 5, first, the top member 6 is joined to the upper part of the bottom body 10. Then, the thong 7 and the front strap 8 are attached to the top member 6 and the bottom member 3.

[0048] In the process of manufacturing the base body 10, a side wall portion 12 and a bottom plate portion 13 are prepared as a single unit. Next, a sheet-like decorative member 23 having a decorative surface 24 is placed along the inner circumferential surface of the side wall portion 12, and the decorative surface 24 is brought into contact with the inner circumferential surface 12e of the side wall portion 12. At this time, a ring-shaped decorative member 23 is formed by joining both ends of a strip-shaped sheet material such as cloth by sewing or the like. The joint portion 23a of the decorative member 23 is placed, for example, on the toe side portion 12a of the side wall portion 12.

[0049] Next, the decorative member 23 is held between the ring-shaped retaining member 25, which extends along the inner circumferential surface 12e of the side wall portion 12, and the side wall portion 12. At this time, the ring-shaped retaining member 25 is formed by attaching both ends of a strip-shaped sheet material such as synthetic resin with adhesive tape 26. The joint portion 25a of the retaining member 25 is positioned on one of the side portions 12d of the side wall portion 12.

[0050] In the process of attaching the thong 7 and the front strap 8 to the top member 6 and the bottom member 3, the tip 8a of the front strap 8, which extends downward through the top member 6, is passed through the first opening 31 and the first through hole 21 of the bottom body 10 and housed in the first recess 33. Next, the tip 8a of the front strap 8 is locked and secured within the first recess 33 with a locking device 37, and the first tongue piece 11a is closed. Furthermore, the two rear ends 7a of the thong 7, which extend downward through the top member 6, are passed through the second opening 32 and the second through hole 22 of the bottom body 10 and housed in the second recess 34. Subsequently, within the second recess 34, the two rear ends 7a of the thong 7 are joined together with hook-and-loop fasteners, and the second tongue piece 11b is closed. In this way, the sandal 1 is manufactured.

[0051] As described above, according to this embodiment 1, the decorative member 23 is held between the transparent or translucent side wall portion 12 and the holding member 25, and the decorative surface 24 of the decorative member 23 is visible from the outside through the side wall portion 12. Therefore, the decorative surface 24 can be protected by the side wall portion 12 while the side surface 24 can decorate the side of the bottom member 3.

[0052] Furthermore, the ring-shaped retaining member 25 extending along the inner circumferential surface 23b of the decorative member 23 allows the decorative member 23 to be properly held even if it is thin and has an unstable shape (for example, made of cloth or paper). Therefore, adhesive is not required to fix the decorative member 23 to the side wall 12, preventing the decorative surface 24 from being stained with unnecessary adhesive. Moreover, multiple processes such as the bonding process for the decorative member 23 and the coating process for the protective film are also unnecessary. Thus, the decorative surface 24 decorating the side of the bottom member 3 can be protected in an aesthetically pleasing and simple manner without being stained with adhesive.

[0053] Here, the bottom member 3 of the sandal 1 intermittently receives vertical impact loads during use. Although the bottom body 10 bears the load, the decorative member 23 and the retaining member 25 are continuously subjected to vibrations associated with the load. As a result, the decorative member 23 may move slightly within the bottom body 10 and may shift. Therefore, even if the sandal 1 is used continuously, it is necessary to securely hold the decorative member 23 with the retaining member 25. In contrast, in this embodiment 1, the retaining member 25, which extends in a band shape along the inner circumferential surface 12e of the side wall 12, is a horizontally elongated shape that is inherently weak against vertical external forces. However, because it is a cylindrical ring structure that extends vertically and curves along the side wall 12, it is less likely to bend even when subjected to vertical vibrations. Furthermore, since the retaining member 25 is in surface contact with the decorative member 23 around its entire circumference, it is less likely to shift vertically along the decorative member 23. Therefore, even if the retaining member 25 is subjected to large vibrations during use, it can maintain surface contact with the decorative member 23 and reliably hold the decorative member 23.

[0054] Furthermore, even if the retaining member 25 is made of a relatively thin sheet material, it is less likely to bend due to vertical vibrations, and the surface contact state with the decorative member is appropriately maintained. Therefore, the decorative member 23 can be held effectively even with a relatively thin retaining member 25. In particular, since the elastic force of the retaining member 25 biases the decorative member 23 toward the side wall portion 12, the decorative member 23 can be held more securely.

[0055] In addition, in this embodiment 1, the protruding portion 16 formed on the lower surface of the lid portion 14 of the bottom body 10 is configured to hold the retaining member 25 and the decorative member 23 between itself and the side wall portion 12. As a result, the retaining member 25 that holds the decorative member 23 is further held by the protruding portion 16, so the decorative member 23 can be held more securely. In this description, as shown in Figure 10, a configuration in which a protruding ridge 16 is formed on the lower surface of the lid portion 14 has been explained. However, in addition to the protruding ridge 16 on the lid portion 14, a configuration in which a protruding ridge (not shown) opposite to the protruding ridge 16 is provided on the upper surface of the bottom plate portion 13 may also be used. By having these opposing protruding ridges positioned vertically, the holding member 25 and the decorative member 23 can be held more securely at their upper and lower ends.

[0056] As mentioned above, a problem arises in that the decorative member 23 and the retaining member 25 are subjected to continuous large vibrations when the sandals 1 are used. However, in this embodiment 1, the decorative member 23 and the retaining member 25 are ring-shaped, being shorter in the vertical direction (up and down) and longer in the horizontal direction (horizontal). Thus, since the decorative member 23 and the retaining member 25 have a structure that is curved in the horizontal direction, even if the decorative member 23 and the retaining member 25 are fixed in only a few places, their shape is less likely to bend, and they are also less likely to bend in the vertical direction. Therefore, even a relatively small protrusion 16 can adequately support the decorative member 23 and the retaining member 25, and the molding of the lid portion 14 using a mold becomes easier.

[0057] Furthermore, by positioning the joint portion 25a of the holding member 25 on the flat plate-shaped side portions 12d of the side wall portion 12, even if the holding member 25 is made of a synthetic resin material such as PET, the joint portion 25a can be maintained in a planar shape, thereby enabling stable holding of the decorative member 23.

[0058] Furthermore, the decorative member 23 may be formed from a colored transparent material, such as a single color or a gradient pattern. In this case, if the retaining member 25 is also formed from a colored transparent material, the overlapping of the retaining member 25's color with the decorative member 23's color allows for a change in color to be enjoyed. Additionally, by providing multiple pieces of at least one of the decorative member 23 and the retaining member 25, the effect of overlapping more colors can be obtained. Embodiment 2

[0059] Next, Embodiment 2 will be described with reference to Figures 12 and 13. Figure 12 is a perspective view showing the decorative member 53 in Embodiment 2. Figure 13 is a longitudinal cross-sectional view showing an enlarged portion of the bottom body 10 in Embodiment 2. In subsequent embodiments, the same reference numerals are used for the same parts as in Embodiment 1, and their detailed descriptions are omitted.

[0060] In this second embodiment, the sandal 1, like in the first embodiment, has a transparent or translucent bottom member 3 with a circumferentially extending side wall portion 12. In the first embodiment, the decorative member 23 was held between the retaining member 25 and the side wall portion 12, whereas in this second embodiment, the decorative member 53 itself is configured to maintain surface contact with the inner circumferential surface 12e of the side wall portion 12. In other words, the decorative member 53 has the same retaining function as the retaining member 25 in the first embodiment. To put it another way, the decorative member 53 has the same decorative function as the retaining member 25 in the first embodiment.

[0061] As shown in Figures 12 and 13, the decorative member 53 is formed in a ring shape that extends in a band-like manner along the inner circumferential surface 12e of the side wall portion 12. Furthermore, the outer circumferential surface 53b of the decorative member 53 that abuts against the inner circumferential surface 12e of the side wall portion 12 serves as the decorative surface 54. The decorative pattern on the decorative surface 54 is formed, for example, by printing or laser processing.

[0062] The decorative member 53 is made of sheet material. For example, the decorative member 53 is formed in a ring shape by joining both ends of a strip-shaped sheet material at a joint 53a. The joint 53a of the decorative member 53 is formed without the use of adhesive, for example, by attaching adhesive tape 56 with both ends of the sheet material butted together. The joint 53a is located on one side portion 12d of the side wall portion 12.

[0063] The decorative member 53 has dimensions and a shape such that its outer peripheral surface 53b is in close contact with the entire circumference of the inner peripheral surface 12e of the side wall portion 12. As a result, the decorative member 53 is configured to maintain a state in which its outer peripheral surface 53b is in surface contact with the inner peripheral surface 12e of the side wall portion 12.

[0064] The decorative member 53 can be made of, for example, a synthetic resin sheet such as PET. The decorative member 53 is elastic, and its elastic force causes the decorative member 53 itself to be pressed against the side wall portion 12.

[0065] As shown in Figure 13, the decorative member 53 is held in place by a protruding ridge 16 formed on the lid portion 14. Similar to Embodiment 1 above, the protruding ridge 16 is formed to protrude from the lower surface of the lid portion 14.

[0066] As shown in Figure 13, the protruding portion 16 is configured to hold the upper portion of the decorative member 53 between itself and the side wall portion 12. The protruding portion 16 is positioned to support at least a portion of the inner circumferential surface 53c of the decorative member 53.

[0067] According to this second embodiment, the decorative member 53 is configured to maintain a state in which its outer peripheral surface 53b is in surface contact with the inner peripheral surface 12e of the side wall portion 12. Therefore, no adhesive is required to fix the decorative member 53 to the side wall portion 12, and the decorative surface 54 is not soiled with unnecessary adhesive. Thus, this second embodiment also allows for easy and safe protection of the decorative surface without soiling it with adhesive.

[0068] Here, the sole member 3 of the sandal 1 intermittently receives vertical impact loads during use, and the decorative member 53 is also continuously subjected to vibrations associated with the load. In contrast, the decorative member 53, which extends in a band shape along the inner circumferential surface 12e of the side wall 12, is originally a horizontally elongated shape that is weak against vertical external forces, but it has a cylindrical ring structure that extends vertically and curves along the side wall 12, so it is less likely to bend even when subjected to vertical vibrations. Furthermore, since the decorative member 53 is in surface contact with the inner circumferential surface 12e of the side wall 12, the decorative member 53 is less likely to shift vertically along the inner circumferential surface 12e of the side wall 12. Therefore, even if the decorative member 53 is continuously subjected to vibrations during use, it can maintain its surface contact state with the inner circumferential surface 12e of the side wall 12.

[0069] In addition, in this second embodiment, the decorative member 53 is held by being sandwiched between the protruding portion 16 and the side wall portion 12, so that the close contact between the decorative member 53 and the inner circumferential surface 12e of the side wall portion 12 can be maintained more reliably.

[0070] Furthermore, as described above, the decorative member 53 has a cylindrical ring structure that curves along the side wall portion 12 and extends vertically, making it resistant to bending even when subjected to vertical vibrations. Therefore, even if the decorative member 53 is fixed in only a few places by the protruding portion 16, it can maintain its shape and be less likely to collapse. Thus, even a relatively small protruding portion 16 can adequately support the decorative member 53. Embodiment 3

[0071] Next, this third embodiment will be described with reference to Figures 14 and 15. Figure 14 is a plan view showing the light source and power supply housed in the sole body of this third embodiment. Figure 15 is a perspective view showing the external appearance of the footwear in this third embodiment.

[0072] As shown in Figure 14, the sandal 1 in this third embodiment houses multiple light sources 41 and a power supply 42 that supplies current to each light source 41 inside the sole body 10. The light sources 41 are composed of, for example, LEDs. Furthermore, a switch 43 is provided to switch the light sources 41 on or off. In addition, a control circuit (not shown) is provided inside the sole body 10 to control the lighting patterns of the multiple light sources 41 in response to the operation of the switch 43.

[0073] The switch 43 can be housed, for example, in the second recess 34. Therefore, the switch 43 can be operated by opening the second tongue piece 11b of the sole portion 11.

[0074] In this third embodiment, the side wall portion 12, the bottom plate portion 13, and the lid portion 14 are each made of transparent material, thereby acting as light guides for the light source 41. Therefore, the light from the light source 41 enters the side wall portion 12, the bottom plate portion 13, and the lid portion 14, which act as light guides, and is guided so that the bottom body 10 lights up to the side, as shown in Figure 15.

[0075] Furthermore, it is sufficient that at least the side wall portion 12 of the base body 10 acts as a light guide. For example, the decorative member 23 can be made of a light-shielding sheet material, and a notched pattern (not shown) can be formed on the sheet material by laser processing or the like. In this way, a light pattern may be made to appear as light passes through the notched pattern and the side wall portion 12.

[0076] According to this third embodiment, similar to the first embodiment, the decorative member 23 is held between the transparent or translucent side wall portion 12 and the holding member 25. Therefore, the decorative surface 24 that decorates the side of the bottom member 3 can be easily protected without being stained with adhesive. In addition, the light source 41 and power supply 42 can be housed using the internal space of the bottom body 10. The light from the light source 41 can be guided to the side wall portion 12, the bottom plate portion 13 and the lid portion 14, causing the bottom body 10 to emit light to the side. Thus, in this third embodiment, the components of the bottom body 10 are used as light guides, so the bottom member 3 can be lit without separately preparing a light guide. As a result, for example, the lighting of the sandals 1 can give a surprising impression to the viewer. It can also ensure the safety of the user at night.

[0077] In the embodiments 1 and 2 described above, examples of a retaining member 25 made of sheet material were explained, but for example, a ring-shaped retaining member 25 with a relatively large thickness may also be used, and other shapes that are arranged along the inner circumferential surface of the side wall portion 12 are also possible. [Industrial applicability]

[0078] As described above, the present invention is useful for footwear having a protected decorative surface on the side of the sole member and for a method of manufacturing the same. [Explanation of Symbols]
