These are the flowcharts which show another example of the manufacturing method of the shoes in embodiment.

  Hereinafter, an example of a shoe sole in an embodiment of the present invention will be described with reference to the drawings. In each figure, the cross direction parallel to the main surface of the laminated shell structure 10 is defined as the width direction X and the length direction Y, and the direction intersecting the width direction X and the length direction Y is defined as the height direction Z. .

(Configuration of sole 1, shoe 100)
With reference to FIG. 1, an example of the structure of the shoe sole 1 and the shoe 100 in this embodiment is demonstrated. FIG. 1 is a schematic perspective view showing a shoe sole 1 and a shoe 100 in the present embodiment.

  As shown in FIG. 1, the shoe 100 includes a shoe sole 1 and a shoe upper portion 110. The shoe sole 1 is joined to the lower surface 110 a of the shoe upper portion 110. As the shape of the shoe upper part 110, for example, a boot type may be used, and for example, a leather shoe type, a shoe type, a high heel type, or the like may be used.

<Laminated shell structure 10>
The shoe sole 1 includes a laminated shell structure 10. The laminated shell structure 10 is joined to the lower surface 110 a of the shoe upper part 110. The laminated shell structure 10 is formed by joining a plurality of layers. FIG. 1 shows a state where the bonded layers of the laminated shell structure 10 are separated.

  The upper surface of the laminated shell structure 10 has the same shape as the conventional one. For this reason, it is not necessary to change the design of the shoe upper part 110 with the joining of the shoe sole 1, and the specification of the shoe upper part 110 can be arbitrarily set. The laminated shell structure 10 can be joined regardless of the type of the shoe upper part 110.

  The laminated shell structure 10 has a storage space 12a, and a control device 7 including electronic components is disposed in the storage space 12a. That is, the shoe sole 1 is for arranging the control device 7 and can have a function corresponding to the control device 7.

  The laminated shell structure 10 includes a toe portion 10f located in the front in the length direction Y and a heel portion 10s located in the rear in the length direction Y. At the top of the toe portion 10f, for example, a toe cap of the shoe upper portion 110 is provided. For example, the heel of the shoe upper portion 110 is provided on the upper portion of the heel portion 10s. When using the shoe 100, the toe portion 10f and the heel portion 10s are less susceptible to deformation due to walking than the other portions. In addition, the laminated shell structure 10 has a top lift 10c located at the bottom end of the heel portion 10s. When using the shoes 100, the top lift 10c is more susceptible to deterioration (scraping) associated with walking than other parts.

<Decorative face layer 11, storage layer 12, bonding layer 13>
The laminated shell structure 10 includes a decorative surface layer 11, a storage layer 12, and a bonding layer 13. The decorative surface layer 11 and the storage layer 12 may be provided only on the heel portion 10s, or may be provided integrally from the toe portion 10f to the heel portion 10s as shown in FIG. 2, for example. In the heel portion 10s, the side surface of the decorative surface layer 11, the side surface of the storage layer 12, and the side surface of the bonding layer 13 are formed on the same plane, for example. Here, the “side surface” refers to the outer peripheral surface of the laminated shell structure 10.

  According to the present embodiment, the shape of the decorative layer 11 and the storage layer 12 may have any shape shown in FIGS. 1 and 2 and can be arbitrarily set according to the design of the shoe 100 or the like. it can. As shown in FIG. 1, when the decorative surface layer 11 and the storage layer 12 are provided only on the heel portion 10 s, portions other than the heel portion 10 s can be formed thin, and the entire shoe sole 1 can be reduced in weight. Become.

  The decorative surface layer 11 is provided on the bottom surface of the laminated shell structure 10 and covers the lower side of the storage space 12a. The storage layer 12 is provided on the decorative surface layer 11 and includes a storage space 12a. The bonding layer 13 is provided on the storage layer 12 and covers the upper side of the storage space 12a. For this reason, the storage space 12 a is provided between the decorative surface layer 11 and the bonding layer 13. Further, the entire control device 7 can be accommodated in the laminated shell structure 10.

  In addition to penetrating the storage layer 12 in the height direction Z, the storage space 12a may be formed in a concave shape having a bottom surface, for example. The storage space 12a can be arbitrarily formed according to the shape of the control device 7 to be arranged, and is formed in, for example, a rectangular shape or a cylindrical shape.

  For example, in the decorative surface layer 11 in the heel portion 10s, the surface covering the storage space 12a and the surface in contact with the storage layer 12 are provided on the same plane. For this reason, it is not necessary to form the makeup | decoration face layer 11 thinly with arrangement | positioning of the control apparatus 7. FIG. Thereby, it becomes possible to suppress the strength reduction of the shoe sole 1. In addition, it is possible to easily perform replacement accompanying the deterioration of the decorative surface layer 11.

  For example, in the bonding layer 13 in the heel portion 10s, the surface covering the storage space 12a and the surface in contact with the storage layer 12 are provided on the same plane. For this reason, it is not necessary to form the bonding layer 13 thin with the arrangement of the control device 7. Thereby, it becomes possible to suppress the strength reduction of the shoe sole 1. In addition, it is possible to easily perform the exchange accompanying the deterioration of the bonding layer 13.

  The storage space 12a is provided in the heel portion 10s, for example, and is separated from portions other than the heel portion 10s. At this time, the storage space 12a is prevented from being affected by damage unique to the sole 1 such as a heel strike. For this reason, the strength reduction of the shoe sole 1 resulting from formation of the storage space 12a can be suppressed.

  For example, the storage space 12a is separated by 7 mm or more along the length direction Y from the top lift 10c. In this case, when the shoe 100 is used, the influence on the control device 7 due to deterioration of the top lift 10c accompanying walking can be suppressed. Thereby, it becomes possible to suppress the deterioration of the control device 7.

  For example, the storage space 12 a is separated from the bottom surface of the decorative surface layer 11 by 3 mm or more. In this case, when using the shoes 100, it is possible to suppress the influence on the control device 7 due to the deterioration of the decorative surface layer 11 accompanying walking. Thereby, it becomes possible to suppress the deterioration of the control device 7.

  For example, the storage space 12 a is separated from the side surface in the width direction X of the storage layer 12 by 15 mm or more. In this case, when the shoe sole 1 is joined to the shoe upper portion 110, the possibility that a nail or the like penetrates the storage space 12a can be reduced. Thereby, it is possible to prevent the control device 7 from being damaged when the shoe sole 1 and the shoe upper portion 110 are joined.

  For example, the thickness of the decorative surface layer 11 is 3 mm or more, and the thickness of the bonding layer 13 is 5 mm or more. In this case, the durability of the shoe sole 1 can be improved. Moreover, since the joining layer 13 has a predetermined thickness, the shoe sole 1 and the shoe upper part 110 can be easily joined.

  For example, as shown in FIG. 2, the storage layer 12 may have a charging space 12b formed integrally with the storage space 12a. The charging space 12b can be inserted with a charging cable or the like connected to the control device 7 disposed in the storage space 12a.

  For example, the storage layer 12 may be formed of two or more layers. In this case, the control device 7 having a height can be accommodated in the laminated shell structure 10.

  As each layer 11-13 which the laminated shell structure 10 has, for example, synthetic rubber, urethane rubber, foamed rubber, EVA (Ethylene-Vinyl Acetate Copolymer) or the like is used. Different materials may be used for the layers 11 to 13.

  For example, a material having higher strength than the storage layer 12 and the bonding layer 13 is used for the decorative surface layer 11. In this case, the strength can be partially increased in the laminated shell structure 10, and the weight of the entire shoe sole 1 can be reduced.

  For example, the bonding layer 13 is made of a material having a higher elastic modulus or a higher repulsion rate than materials used for the decorative layer 11 and the storage layer 12. In this case, comfort when using the shoe 100 can be improved.

  For example, only a rubber-based material may be used for the laminated shell structure 10. In this case, it is possible to smoothly transmit and receive various types of information in the stored control device 7.

<Wiring unit 14>
For example, as shown in FIG. 3, the laminated shell structure 10 includes a wiring portion 14 provided between a decorative surface layer 11 and a bonding layer 13. For example, the wiring part 14 is sandwiched between the decorative surface layer 11 and the storage layer 12. That is, the wiring part 14 is not exposed on the surface of the laminated shell structure 10.

  The wiring unit 14 is connected to the control device 7 disposed in the storage space 12a. For example, when the control device 7 includes the sensor unit 71 disposed in the storage layer 12, the wiring unit 14 is connected to the control device 7 and the sensor unit 71. Thereby, the control device 7 can control the sensor unit 71 via the wiring unit 14 in a state where the wiring unit 14 is not exposed on the surface of the laminated shell structure 10.

  For example, when a shank (not shown) is disposed on the shoe sole 1, the wiring portion 14 is provided along the shank. For this reason, since the wiring part 14 is supported by the shank, it becomes possible to suppress the deterioration of the wiring part 14.

  For example, the wiring portion 14 may have a slack portion in a region between the toe portion 10f and the heel portion 10s. For this reason, when using shoes 100, it becomes possible to control degradation of wiring part 14 resulting from a deformation of lamination shell structure 10 accompanying walking.

  As the wiring part 14, a copper wire with an insulating film is used, and for example, a thin film conductive member may be used.

  For example, as shown in FIG. 4, the storage layer 12 may have a wiring space 12c formed integrally with the storage space 12a. In this case, the wiring part 14 can be stored in the wiring space 12c. For this reason, it is possible to suppress the displacement and deterioration of the wiring portion 14 due to the joining of the layers of the laminated shell structure 10. Thereby, simplification of a manufacturing process can be achieved. Moreover, when using the shoes 100, it becomes possible to suppress the deterioration of the wiring part 14 accompanying walking.

<Recess 12d>
For example, as shown in FIG. 5, the storage layer 12 may have a recess 12 d provided on a side surface. The recess 12d is provided in the toe portion 10f, for example. The recess 12 d is provided between the decorative surface layer 11 and the bonding layer 13. A plurality of recesses 12d may be provided.

  For example, the sensor unit 72 included in the control device 7 is disposed in the recess 12d. The recess 12 d is formed on the inner side with respect to the side surface of the decorative surface layer 11 and the side surface of the bonding layer 13. For this reason, it can arrange | position so that the sensor part 72 may not protrude from the shoe sole 1. FIG.

  For example, the recess 12d is provided at a position 15 mm or more away from the toe portion 10f side in the length direction Y with reference to the position of the maximum width W1 in the width direction X of the laminated shell structure 10. In this case, when the shoe 100 is used, the sensor unit 72 can be disposed at a position that is not affected by the deformation of the laminated shell structure 10 associated with walking. Thereby, it is possible to suppress the deterioration of the sensor unit 72.

  The sensor unit 72 is connected to the control device 7 via the wiring unit 14. In this case, the control device 7 can control the sensor unit 72 via the wiring unit 14. For example, the sensor unit 72 may be connected to the control device 7 via wireless communication.

  For example, as shown in FIG. 6, the laminated shell structure 10 may include a protective member 15 provided in a part of the recess 12 d. By providing the protection member 15, it is possible to suppress the deterioration of the sensor unit 72. In addition to the above, when, for example, silicon is used as the protection member 15, it is possible to improve waterproofness. Moreover, when resin or a plastic is used as the protection member 15, for example, it is possible to suppress a decrease in strength of the shoe sole 1.

  For example, as shown in FIG. 7, the storage layer 12 may have a wiring space 12c formed integrally with the storage space 12a and the recess 12d. In this case, the manufacturing process can be simplified as in the configuration described above. Moreover, when using the shoes 100, it becomes possible to suppress the deterioration of the wiring part 14 accompanying walking.

<Stuck-proof part 16>
For example, as shown in FIG. 8, the laminated shell structure 10 includes a tread-resistant portion 16 provided between the decorative surface layer 11 and the bonding layer 13. The tread-resistant portion 16 has a shape equal to that of the decorative surface layer 11, for example. The tread-proof portion 16 is provided, for example, between the decorative surface layer 11 and the storage layer 12, and covers the lower side of the storage space 12a. For this reason, the strength fall of the shoe sole 1 resulting from formation of the storage space 12a can be compensated.

  The tread-resistant part 16 may be provided on the wiring part 14, for example, and the wiring part 14 may be sandwiched between the decorative surface layer 11 and the tread-resistant part 16. In this case, when the shoe 100 is used, it is possible to suppress the deterioration of the wiring portion 14 due to stepping or the like.

  The tread-proof portion 16 may include a reinforcing portion 16a provided between the storage layer 12 and the bonding layer 13, for example. By providing the reinforcing portion 16a, it is possible to further suppress deterioration of the control device 7 due to stepping or the like when the shoe 100 is used.

  Further, the tread-resistant portion 16 is provided in the laminated shell structure 10. For this reason, when joining the shoe sole 1 having the tread resistant part 16 to the shoe upper part 110, it is not necessary to change the shape of the conventional shoe upper part 110. As a result, the shoe sole 1 and the shoe upper portion 110 can be easily joined.

  For example, in the ruggedness portion 16 in the heel portion 10s, the surface covering the storage space 12a and the surface in contact with the storage layer 12 are provided on the same plane. In this case, it is not necessary to form a recess or the like for arranging the control device 7 in the tread-resistant portion 16. For this reason, it becomes possible to form easily the shape of the tread-resistant part 16.

  For example, the tread-proof portion 16 may be provided only under the storage space 12a. In this case, the strength reduction of the shoe sole 1 due to the formation of the storage space 12a can be compensated in a state in which the weight of the shoe sole 1 is suppressed.

  For example, a material having a hardness higher than that of the storage layer 12 is used as the ruggedness portion 16. Stainless steel is used as the step-through resistant portion 16. For this reason, the step-out resistance (step-through resistance) of the shoe sole 1 can be improved. Thereby, when the shoe sole 1 is used as the shoe 100, it is possible to further suppress the deterioration of the control device 7 due to use. In particular, it is possible to further improve the step-out resistance by setting the thickness of the step-through portion 16 to 0.5 mm or more.

  According to the present embodiment, the laminated shell structure 10 having the pierce-proof portion 16 can realize 1100 N or more or 1300 N or more in the step-out resistance test (JIS 8101). For example, the shoe sole 1 is used for safety shoes. Is possible.

  For example, a material having a higher tensile strength than the storage layer 12 may be used as the ruggedness resistant portion 16. In this case, an aromatic polyamide-based resin (for example, Kepler (registered trademark)) is used as the rugged portion 16. In this case, when the shoe sole 1 is used as the shoe 100, it is possible to further suppress the deterioration of the control device 7 accompanying use.

<Nail hole 17>
For example, as shown in FIG. 9, the laminated shell structure 10 has a nail hole portion 17 that penetrates from the decorative surface layer 11 to the bonding layer 13. The nail hole portion 17 is separated from the storage space 12a. For example, when at least any one of the charging space 12b, the wiring space 12c, and the recess 12d is provided, the nail hole portion 17 is separated from the components 12b to 12d. In this case, when the shoe sole 1 and the shoe upper portion 110 are joined, the joining can be easily performed without damaging the control device 7 or the like. This makes it possible to simplify the manufacturing process. Note that the number of the nail hole portions 17 is arbitrary.

<Control device 7>
In the shoe sole 1 in the present embodiment, an arbitrary control device 7 and sensor units 71 and 72 can be set according to applications. Hereinafter, an example of the control device 7 and the sensor units 71 and 72 will be described.
