The X-axis, Y-axis, and Z-axis shown in the drawings represent Cartesian coordinates arbitrarily set for the purpose of illustrating the drawings. In other words, the Z-axis is not necessarily an axis along the vertical direction, and the X-axis and Y-axis are not necessarily located within a horizontal plane.

[0012] In addition, in the following, a plurality of disclosures may be collectively described as one embodiment, and some of the contents described below may be described as optional components related to the present disclosure.

[0013] FIG. 1 is a perspective view of a shoe 100. FIG. 2 is an exploded perspective view of the shoe 100. FIG. 3 is a cross-sectional view showing the heel portion of the shoe 100. Note that while FIGS. 1 and 2 show a shoe for a left foot, a shoe for a right foot may be similar (as a mirror image). The shoe 100 includes an upper 110, an insole 120, an outsole 130, and a display unit 140. The type of shoe 100 is not limited to the athletic shoes (sneakers) shown in the figures. It may also be any footwear that includes an upper 110 and a sole member (including the insole 120 and outsole 130), such as slippers, sandals, or other open-toe footwear, or boots that cover the ankles, shins, calves, etc.

[0014] The upper 110 is a part that secures the shoe 100 to the user's foot. The material that constitutes the upper 110 is not limited, and examples include textiles, foam resin, natural leather, synthetic leather, etc. The upper 110 also includes band-like or string-like members that are wrapped around the instep, ankle, etc.

[0015] The sole member is attached to a lower portion of the upper 110 and is disposed between the ground and the foot fixed to the upper 110. The sole member may be divided into multiple layers, each of which may be given a name, but in this embodiment, the sole member is divided into two layers, and the layer of the sole member disposed on the foot side is referred to as the insole 120, and the layer of the sole member disposed on the ground side is referred to as the outsole 130.

[0016] The insole 120 is disposed on the bottom of the upper 110 and is a part that comes into direct or indirect contact with the sole of the foot fixed to the upper 110. In the present embodiment, the insole 120 is fixed so as to cover the bottom of the upper 110. Note that the insole 120 may include a component that is removably disposed within the upper 110.

[0017] The outsole 130 is connected to the ground side of the insole 120, and is a member that attenuates impacts from the ground and generates friction by contacting the ground. The outsole 130 is provided with a storage section 131 that stores a portion of the display unit 140. In the present embodiment, as a typical example, the storage section 131 is a concave portion that opens toward the upper 110 (insole 120) and is recessed toward the ground. The shape of the storage section 131 corresponds to the shape of the portion of the display unit 140 that it stores, but does not necessarily have to match as long as the shape is suitable for storage. In the present embodiment, the shape of the storage section 131 and the shape of the portion of the display unit 140 that it stores are roughly the same, and because the portion of the display unit 140 that the storage section 131 stores is rectangular, the shape of the storage section 131 is also rectangular.

[0018] The method of joining the outsole 130 to the upper 110 and the insole 120 is not limited, and examples of joining methods include stitching, adhesive bonding, welding, and fastening. In the present embodiment, the outsole 130 is detachable from the upper 110 and the insole 120, and the housing 131 can be exposed by removing the outsole 130 from the upper 110 and the insole 120. This allows maintenance of the display unit 140.

[0019] FIG. 4 is a perspective view showing the display unit 140 in an exploded state. The display unit 140 is a unit capable of displaying at least one type of image, such as a color, pattern, or text, and includes a display device 141, a display control device 142, and a housing 143. The display unit 140 may also display moving images by displaying different images at predetermined time intervals. Here, the display unit 140 may be configured to include either or both of a photovoltaic element 144 and a switch 145. As an example, in this embodiment, the display unit 140 includes both the photovoltaic element 144 and the switch 145.

[0020] The display device 141 is disposed in a shape that conforms to the outer surface shape of the upper 110 and is capable of displaying images, including colors, patterns, text, and moving images. The type of display device 141 is not limited, and examples thereof include electronic paper, a liquid crystal display, and an organic electroluminescence (EL) display. The display device 141 may be flexible enough to conform to the outer surface shape of the upper 110, or may be manufactured to conform to the outer surface shape of the upper 110. In this embodiment, the display device 141 is connected to the display control device 142 via a flat cable 146 having a plurality of conductors arranged in a planar shape and equipped with connectors at the ends. Note that a cable such as a wire harness, a cable harness, a flexible flat cable (FFC), or an FP cable (FPC) may be used instead of the flat cable 146.

[0021] The position of the display device 141 on the upper 110 is not limited, but in this embodiment, the display device 141 is curved and positioned so as to cover the heel portion of the upper 110 from the outside to the inside of the foot. In this embodiment, the display device 141 has a cutout at the top of the part corresponding to the rear of the foot in order to position the photovoltaic member 144.

[0022] The display control device 142 is a device that displays an image on the display device 141, and is formed on a substrate 147. The substrate 147 is provided with a connector for connecting to the display device 141. In the present embodiment, the substrate 147 is further provided with a connector for connecting to the photovoltaic element 144 and a connector for connecting to the switch 145. By using the connectors provided on the substrate 147, the display device 141, the photovoltaic element 144, and the switch 145 can be easily disconnected from and connected to the display control device 142.

[0023] The substrate 147 is fitted with a battery 148 that supplies power to the display device 141 and the display control device 142 and is charged by the photovoltaic element 144 .

[0024] Photovoltaic member 144 is a so-called solar cell that generates electricity using light such as sunlight. Like display device 141, photovoltaic member 144 is preferably arranged in a shape that follows the shape of the outer surface of upper 110. Photovoltaic member 144 may be a perovskite solar cell that follows the shape of the outer surface of upper 110 due to its flexibility, or may be a silicon solar cell manufactured to follow the shape of the outer surface of upper 110. In the present embodiment, photovoltaic member 144 is connected to battery 148 via a conductor equipped with a connector at its tip.

[0025] The position of the photovoltaic member 144 on the upper 110 is not limited, but in this embodiment, it is located in the part of the upper 110 that corresponds to the rear of the foot, and is positioned so as to fit into a notch provided in the display device 141. The upper edge of the photovoltaic member 144 is positioned at the same height as the upper edge of the display device 141.

[0026] The switch 145 outputs to the display control device 142 a signal for, for example, turning on / off the display of the display device 141 or switching the content displayed on the display device 141. The type of the switch 145 is not limited, but in this embodiment, the switch 145 is a push-button switch.

[0027] The housing 143 is a member that houses the display device 141 and the display control device 142. In the present embodiment, the housing 143 also houses the photovoltaic component 144, various conductors, various connectors, a circuit board 147, a battery 148, and the like. The housing 143 includes a clamping section 151, a gap section 152, and an electrical section 153.

[0028] The clamping portion 151 is disposed on the outside of the upper 110 and is a portion that holds at least the display device 141 in a clamped state. In the present embodiment, the clamping portion 151 holds the photovoltaic member 144 in a clamped state. The clamping portion 151 also holds the switch 145 at its upper end. The shape of the clamping portion 151 corresponds to the shape of the display device 141 that it holds. In the present embodiment, the shape of the clamping portion 151 when viewed from above is U-shaped and covers the heel portion of the upper 110.

[0029] The clamping portion 151 is composed of an inner clamping portion 154 arranged on the upper 110 side and an outer clamping portion 155 arranged outside the inner clamping portion 154, and the display device 141 and the photovoltaic element 144 are held in a sandwiched state between the inner clamping portion 154 and the outer clamping portion 155.

[0030] Here, the upper 110 and the clamping portion 151 may or may not be connected and fixed. Alternatively, the upper 110 and the clamping portion 151 may be partially connected and fixed. When fixed, for example, they may be bonded and fixed using an adhesive, or they may be fastened and fixed using screws. By fixing the upper 110 and the clamping portion 151, the strength around the heel is improved. When they are not fixed, the part that comes into contact with the user's heel remains in the same state as a normal shoe, ensuring comfort for the user. In the configuration of FIG. 3, the upper 110 and the clamping portion 151 are not connected and fixed.

[0031] The inner clamping portion 154 has an inner flange 156 integrally formed on its upper edge and its vertically extending edge, which protrudes outward. The inner flange 156 covers the upper edge and the vertically extending edge of the attached outer clamping portion 155. The inner flange 156 functions as a rib that improves the structural strength of the inner clamping portion 154. The inner flange 156 is also bonded to the outer clamping portion 155 with an adhesive or the like, thereby improving the degree of sealing between the outer clamping portion 155 and the inner clamping portion 155.

[0032] The outer clamping portion 155 is integrally provided with an outer flange 157 that protrudes inward from its upper edge. The outer flange 157 abuts against the outer surface of the inner clamping portion 154, thereby ensuring a space (gap) for arranging the display device 141 and the photovoltaic component 144. The outer flange 157 functions as a rib that improves the structural strength of the outer clamping portion 155. The outer flange 157 is joined to the inner flange 156 with an adhesive or the like while overlapping in the vertical direction, thereby improving the sealing between the inner clamping portion 154 and the outer clamping portion 155. The outer clamping portion 155 has a wall 158 that separates the clamped display device 141 and the photovoltaic component 144 and determines the position of the photovoltaic component 144.

[0033] Gap portion 152 is fixed to shoe 100 while being sandwiched between insole 120 and outsole 130, and is a portion that holds clamping portion 151 at a predetermined position on the outside of upper 110. Gap portion 152 is plate-shaped, and the shape of the rear edge is curved to correspond to the U-shaped clamping portion 151.

[0034] The gap 152 is composed of an upper gap 161 arranged on the insole 120 side and a lower gap 162 arranged on the outsole 130 side.

[0035] The upper gap 161 is flat. The inner clamping portion 154 extends integrally from a portion of the periphery of the upper gap 161. This improves the structural strength of the inner clamping portion 154 and the upper gap 161.

[0036] The lower gap 162 is flat. The outer clamping portion 155 extends integrally from a portion of the periphery of the lower gap 162. This improves the structural strength of the outer clamping portion 155 and the lower gap 162. The lower gap 162 is provided with an insertion hole 163 that penetrates in the thickness direction (vertical direction) and communicates with the interior space of the electrical unit 153. Furthermore, at least one of the lower gap 162 and the upper gap 161 (only the lower gap 162 in this embodiment) is provided with a wiring groove 164 that communicates with the insertion hole 163. Wires extending from the display device 141, the photovoltaic component 144, and the switch 145 can be routed through the wiring groove 164 and connected to the display control device 142 housed in the electrical unit 153 via the insertion hole 163.

[0037] The electrical unit 153 is disposed in the housing 131 of the outsole 130 and houses at least the display control device 142. In the present embodiment, the electrical unit 153 is in the shape of a container that opens toward the gap 152, and the display control device 142, battery 148, circuit board 147, etc. are housed in the internal housing space. The shape of the electrical unit 153 is not limited, and any shape is sufficient as long as it can house at least the display control device 142. A flange 165 is provided on the edge of the open end of the electrical unit 153. The flange 165 increases the contact area with the lower surface of the lower gap 162, thereby improving the degree of sealing with the connected lower gap 162.

[0038] When the electrical part 153 is attached to the lower gap 162, the electrical part 153 is sealed and waterproof except for the insertion hole 163. The electrical part 153 is attached to the lower gap 162 so that it can be removed from the lower gap 162.

[0039] The material of the housing 143 is not particularly limited, but the portion of the outer clamping portion 155 facing the display device 141 and the portion facing the photovoltaic member 144 are made of a material that has light-transmitting properties, such as transparent or translucent. This allows the image displayed on the display device 141 to be seen from the outside and allows light to reach the photovoltaic member 144. In this embodiment, the material of the housing 143 is resin. The inner clamping portion 154 and the upper gap portion 161 are molded integrally by resin molding. The outer clamping portion 155 and the lower gap portion 162 are also molded integrally by resin molding. The electrical portion 153 is also a resin molded product.

[0040] Next, an example of a manufacturing method for the display unit 140 will be described. The display device 141, photovoltaic component 144, and switch 145 are attached to the outer clamping portion 155, and the conductors extending from the display device 141, photovoltaic component 144, and switch 145 are routed through the wiring grooves 164 in the lower gap 162 integral with the outer clamping portion 155. Connectors on each conductor are passed through the insertion holes 163. The integral inner clamping portion 154 and upper gap 161 are connected to the integral outer clamping portion 155 and lower gap 162. While the connection method is not limited, in this embodiment, connection using an adhesive is exemplified. The adhesive is applied along the edges of the inner clamping portion 154 and outer clamping portion 155, except for the insertion holes 163, to seal the gap between them. Furthermore, adhesive is applied in a planar manner between the upper gap 161 and the lower gap 162. The wiring groove 164 and the insertion hole 163 may be filled with an adhesive or the like.

[0041] Next, the connector drawn out from the insertion hole 163 is connected to the corresponding connector on the board 147, and the board 147 is housed in the electrical part 153. The flange part 165 of the electrical part 153 and the lower gap part 162 are connected using an adhesive so as to ensure a sealed state.

[0042] As a result, the housing 143 is sealed, preventing the intrusion of liquids such as water and protecting the devices, components, etc. housed in the housing 143 from liquids. Furthermore, the structural strength of the housing 143 can protect the devices, components, etc. housed in the housing 143 from pressure and the like from the outside. Of course, the housing 143 can also prevent the intrusion of solids such as sand and dust.

[0043] Next, inner clamping portion 154, which is located on the upper 110 side of clamping portion 151, is placed on the surface of upper 110, upper gap portion 161, which is located on the insole 120 side of gap portion 152, is attached to the surface of insole 120 on the outsole 130 side, electrical portion 153 is placed in storage portion 131 provided in outsole 130, and upper 110, insole 120, and outsole 130 are joined together. In this manner, shoe 100 is manufactured.

[0044] The shoe 100 according to the embodiment comprises an upper 110, an insole 120 connected to the lower part of the upper 110, an outsole 130 connected to the lower part of the insole 120, and a display unit 140 capable of displaying images. The display unit 140 comprises a display device 141 arranged in a shape that conforms to the outer surface of the upper 110, a display control device 142 that causes the display device 141 to display images, and a housing 143 that houses the display device 141 and the display control device 142. The housing 143 comprises a clamping section 151 that is arranged on the outside of the upper 110 and that clamps and holds the display device 141, a gap section 152 that is arranged between the insole 120 and the outsole 130, and an electrical section 153 that is arranged below the insole 120 and that houses the display control device 142.

[0045] Such shoe 100 can prevent display device 141 from being deformed due to distortion of shoe 100 during walking, etc., and from falling off upper 110 or breaking down. Furthermore, even if shoe 100 gets wet due to rain or the like, housing 143 is sealed, so water does not seep into the interior, and display device 141, display control device 142, etc. can be protected from water.

[0046] In addition, the clamping portion 151 has an inner clamping portion 154 arranged on the upper 110 side and an outer clamping portion 155 arranged outside the inner clamping portion 154, the gap portion 152 has an upper gap portion 161 arranged on the insole 120 side and a lower gap portion 162 arranged on the outsole 130 side, and the electrical portion 153 is container-shaped and opens toward the gap portion 152.

[0047] According to such a shoe 100, the display device 141 that displays an image can be easily arranged on the outside of the upper 110, and the display control device 142 can be easily arranged on the outsole 130.

[0048] Furthermore, the lower gap portion 162 and the electrical portion 153 may be detachable and waterproof when attached.

[0049] According to such a shoe 100, the display unit 140 can be easily maintained.

[0050] Alternatively, the inner clamping portion 154 may be integrally extended from a portion of the periphery of the upper gap 161 , and the outer clamping portion 155 may be integrally extended from a portion of the periphery of the lower gap 162 .

[0051] According to such a shoe 100, the housing 143 can be structurally strengthened, and even if the shoe 100 is made of a lightweight material, the display device 141 can be sufficiently protected.

[0052] Furthermore, a photovoltaic element 144 that generates electricity using light may be provided, and the photovoltaic element 144 may be housed in the clamping portion 151 .

[0053] According to such shoes 100, the power required to display an image can be supplied to the battery 148 without opening the housing 143.

[0054] Furthermore, a manufacturing method of shoe 100 according to an embodiment is a manufacturing method of shoe 100 including upper 110, insole 120 connected to the lower part of upper 110, outsole 130 connected to the lower part of insole 120, and display unit 140 capable of displaying images, wherein display unit 140 includes display device 141 arranged in a shape along the outer surface of upper 110, display control device 142 that causes display device 141 to display images, and housing 143 that houses display device 141 and display control device 142, and housing 143 includes clamping section 151 arranged on the outside of upper 110 and clamping and holding display device 141, gap section 152 arranged between insole 120 and outsole 130, and electrical section 153 arranged below insole 120 and accommodating display control device 142, An inner clamping portion 154 arranged on the 10 side is attached to the surface of the upper 110, an upper gap portion 161 arranged on the insole 120 side of the gap portion 152 is attached to the surface of the insole 120 on the outsole 130 side, a display device 141 is arranged in the gap between the inner clamping portion 154 and an outer clamping portion 155 arranged on the outside of the inner clamping portion 154, and a display device 141 is arranged in the gap between the upper gap portion 161 and a lower gap portion 162 arranged on the outsole 130 side. A conducting wire is arranged to electrically connect the display device 141 and the display control device 142, the display control device 142 is arranged inside a container-shaped electrical section 153, the inner clamping section 154, the outer clamping section 155, the upper gap section 161, the lower gap section 162, and the electrical section 153 are joined together to seal the housing 143, the electrical section 153 is arranged in a storage section provided in the outsole 130, and the upper 110 or the insole 120 and the outsole 130 are joined together.

[0055] According to this manufacturing method of the shoe 100, the manufacturing of the upper 110 and the outsole 130 and the manufacturing of the display unit 140 can be divided into separate tasks, thereby improving the manufacturing efficiency of the shoe 100.

[0056] It should be noted that the present disclosure is not limited to the above-described embodiments. For example, the present disclosure may be embodied in another embodiment realized by any combination of the components described in this specification or by excluding some of the components. Furthermore, the present disclosure also includes modifications obtained by applying various modifications to the above-described embodiments that would occur to a person skilled in the art without departing from the spirit of the present disclosure, i.e., the meaning of the wording of the claims.

[0057] For example, the method of joining the components constituting the housing 143 is not limited to adhesive, and welding, fastening, or the like may also be used. In particular, the joining between the lower gap 162 and the electrical unit 153 may be performed by, for example, providing a groove for an O-ring on the upper end surface of the flange portion 165 of the electrical unit 153, and joining the lower gap 162 and the electrical unit 153 with a fastening member such as a bolt. In this way, when the lower gap 162 and the electrical unit 153 are fastened together, a waterproof state can be ensured by the O-ring. Furthermore, by releasing the fastening, the electrical unit 153 can be separated from the lower gap 162, allowing maintenance of the display control device 142, etc.

[0058] Furthermore, instead of including the photovoltaic power generating member 144, it is also possible to include a power generating member that generates electricity from vibrations such as walking, a power generating member that generates electricity from pressure fluctuations caused by walking, or a power generating member such as a coil that generates electricity from electromagnetic induction from outside the shoe 100. If such a power generating member is included, it is placed in a position that takes into consideration ease of power generation. For example, if a power generating member that generates electricity from vibrations is used, it is placed so that the direction of walking and the direction in which vibrations are detected are roughly aligned. If a power generating member that generates electricity from pressure fluctuations is used, it is placed somewhere on the bottom of the shoe 100 (such as on the upper or lower surface of the sole member, between the insole and outsole, or inside the insole or outsole). If a power generating member that generates electricity by electromagnetic induction is used, it is placed on the lower surface of the sole member, for example.

[0059] Furthermore, the location where display device 141 is placed is not limited to the vicinity of the heel, and it may be placed on the toes, instep, side of the foot, etc. Furthermore, the entire upper 110 may be covered with display device 141. Furthermore, multiple display devices 141 may be placed at different locations on upper 110, such as the toes and heel, or the instep and heel.

[0060] In addition, in this embodiment, when the shoe 100 is viewed from the side, the outsole 130 has a continuous structure extending from the toe to the heel. However, this is not limited to this, and the outsole 130 may have a structure divided into multiple sections, as shown in Fig. 5. For example, the outsole 130 may be divided into two sections, one at the front and one at the back, midway from the toe to the heel. Furthermore, in the divided outsole 130, an appropriate space may be provided between the toe-side section and the heel-side section. In this case, the storage section 131 may be provided in the toe-side section or the heel-side section.

[0061] Furthermore, in the above-described embodiment, as a typical example, the storage section 131 has a concave shape that opens toward the upper 110 (insole 120) and is recessed toward the ground, but it need not be such a concave shape. For example, as shown in Fig. 6, the storage section 131 provided in the outsole 130 may have a shape in which a portion of the wall-like portion surrounding the electrical section 153 is cut out when the shoe 100 is viewed from the side. In this case, the storage section 131 is formed in whole or in part by cutting out the space in the outsole 130 from the heel end toward the toe.

[0062] Furthermore, the depth of the cut from the heel end toward the toe end may be constant or may vary across the width of the shoe 100 or across the vertical direction of the shoe 100. For example, as shown in Fig. 7, the cut may be deeper near the center of the width of the shoe 100 and shallower near the side of the shoe 100. When the outsole 130 has such a cut-out shape, a cover may be attached to the display unit 140 or the outsole 130 to cover the cut-out portion.

[0063] The present disclosure can be used for all types of shoes, including leather shoes, sneakers, sandals, boots, and flats.
