Description

[Technical Field]

[0001] This disclosure relates to the last. [Background technology]

[0002] When making shoes, a last (shoe mold) is used to cover the fabric that makes up the upper in order to form the upper into a predetermined shape.

[0003] U.S. Patent Application Publication No. 2018 / 0014609 discloses manufacturing footwear in a portable housing, U.S. Patent Application Publication No. 2016 / 0206049 discloses a remoldable last preform made from shape memory polymers, and Chinese Patent No. 109732913 discloses forming a last by 3D printing. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] US Patent Application Publication No. 2018 / 0014609 [Patent Document 2] US Patent Application Publication No. 2016 / 0206049 [Patent Document 3] Chinese Patent No. 109732913 Summary of the Invention [Problem to be solved by the invention]

[0005] If the entire last is custom-made to form a molded surface that matches the shape of the wearer's foot, it will take a long time to produce.

[0006] On the other hand, it is known that there are parts of the foot where the difference in shape between wearers is relatively small and parts where the difference is relatively large. Therefore, by configuring the parts where the shape is relatively small from unchanging (common) parts and configuring the parts where the shape is relatively large from variable (custom-made) parts and combining them, it becomes possible to relatively easily form any shaped surface that matches the shape of the wearer's foot.

[0007] However, after the upper is formed using such a last, it may be difficult to remove the last from the opening of the upper.

[0008] An object of the present disclosure is to provide a last that can form any desired molding surface relatively easily and that can be easily removed from the upper opening after the upper has been molded. [Means for solving the problem]

[0009] A last according to one aspect of this disclosure is a last having an upper molding surface that molds an upper having an opening portion, and comprises: a base part including a bottom portion that defines the bottom surface of the upper; and a plurality of additional parts, each formed in a plate shape and capable of being assembled to the base part; the base part has an attachment portion for attaching the plurality of additional parts so that the plurality of additional parts are arranged in multiple layers along one direction; and a first molding surface that defines a first region of the upper molding surface; the plurality of additional parts have second molding surfaces that, when attached to the attachment portion, define a second region of the upper molding surface that is different from the first region; each additional part in the plurality of additional parts has an end surface, and the second molding surface is constituted by the end surface of each of the plurality of additional parts; and the base part has a first base member including the attachment portion; and a second base member that is detachable from the first base member. [Effects of the Invention]

[0010] According to this disclosure, it is possible to provide a last that can be formed with any desired molding surface relatively easily and that can be easily removed from the upper opening after the upper has been molded. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0012] An embodiment of the present invention will be described with reference to the drawings. In the drawings referred to below, the same or equivalent components are designated by the same numbers. In the following description, terms such as foot length direction, foot width direction, forward direction, and backward direction are used. These directional terms indicate directions as seen from the perspective of a wearer wearing shoe 1 placed on a flat surface such as the ground. For example, forward refers to the toe side, and backward refers to the heel side.

[0013] FIG. 1 is a perspective view of a shoe made using a last according to an embodiment of the present disclosure. FIG. 2 is a cross-sectional view taken along line II-II in FIG. 1. FIG. 3 is an exploded perspective view of the shoe. Although FIGS. 1 to 3 show a shoe 1 for a left foot, this shoe 1 can also be used for a right foot. The shoe for the right foot has a shape that is symmetrical to the shoe 1 for the left foot, or a shape that is roughly similar to that of the shoe for the left foot. The shoe 1 can be used, for example, as a sports shoe for running or the like, or as a walking shoe, and the use of the shoe 1 is not limited.

[0014] As shown in FIGS. 1 to 3, the shoe 1 includes a sole 2 , an upper 3 , and a shell 4 .

[0015] The sole 2 is made of a resin foam material or the like. The upper 3 is placed on the sole 2. The upper 3 constitutes the part that comes into contact with the wearer's foot and is made of a bag-like member that is flexibly deformable. The upper 3 is made of a fiber sheet containing heat-shrinkable yarn. The upper 3 has an opening part 3a.

[0016] The shell 4 houses the sole 2 and the upper 3. The shell 4 constitutes the outermost shell of the shoe 1 and is made of a single flexible member formed in a bag shape. The shell 4 covers the bottom surface of the sole 2 and the surface of the upper 3.

[0017] FIG. 4 is a diagram showing how a wearer's foot F is photographed to obtain a foot model FM. As shown in FIG. 4, the wearer's foot F is photographed using a mobile device capable of photographing, such as a smartphone P or a digital camera, to obtain image data of the foot F. The image data of the foot F may be photographed at a store visited by the wearer. The store may be a fixed store or a mobile store using a car, trailer, or the like. Alternatively, the image data of the foot F may be photographed at the wearer's home. The wearer may photograph the image data of the foot F themselves and send it to a shoe manufacturer's server.

[0018] Fig. 5 is a perspective view of a foot model FM. The foot model FM shown in Fig. 5 is a three-dimensional foot model generated from measurement data of each part of the wearer's foot F obtained from image data of the foot F. For example, when a photograph of the wearer's foot F is taken with a smartphone P, the foot model FM can be generated based on the image data using software pre-installed on the smartphone P. Alternatively, the foot model FM may be generated by performing calculations using both the photographed image data and data stored in a server used by a shoe manufacturer.

[0019] The foot last model FM may be formed to have the same shape as the shape of the wearer's foot F. Alternatively, for design or functional reasons, certain portions of the foot last model FM may be corrected to the shape of the wearer's foot F by desired dimensions.

[0020] Fig. 6 is a perspective view of a last model LM. The last model LM shown in Fig. 6 is a model of a last customized to fit the shape of a wearer's foot F, created based on the foot shape model FM shown in Fig. 5. A custom-made shoe 1 is produced specifically for the wearer by molding an upper 3 using a last 10 (see Fig. 7) created in accordance with this last model LM.

[0021] 7 is a perspective view of a last according to one embodiment of the present disclosure, created based on a last model. The last 10 has an upper molding surface S1 that molds the upper 3. The last 10 includes a base part 100, a plurality of additional parts 200, and a connecting member 300 (see FIGS. 12 to 14).

[0022] The base part 100 is made of resin, wood material, metal, solidified pulp, etc. As shown in Fig. 8, the base part 100 has a bottom part 110, a mounting part 120, and a first molding surface S10.

[0023] The bottom portion 110 defines the bottom surface of the upper 3. The bottom portion 110 is formed in a flat plate shape. The bottom portion 110 has a shape that extends from the rear end portion to the front end portion of the upper molding surface S1.

[0024] The first molding surface S10 defines a first region of the upper molding surface S1. The first region is a region where the difference in foot shape between wearers is relatively small. In this embodiment, the first region has a toe region R11 and a middle region R12.

[0025] The toe region R11 is a region that forms a part that covers the toes of the wearer in the upper 3. The toe region R11 is formed at the front end of the sole 110.

[0026] The middle region R12 is a region of the upper 3 that forms a portion covering the middle portion of the wearer's foot in the foot length direction. The middle portion is a portion that overlaps the wearer's ankle in the height direction. In other words, the middle region R12 is a region that forms a portion of the upper 3 below the opening portion 3a. The middle region R12 includes an opening portion forming portion S12 that forms the opening portion 3a.

[0027] The mounting section 120 is a section for mounting the multiple additional parts 200 so that the multiple additional parts 200 are arranged in multiple layers in one direction. As shown in FIGS. 8 to 10 , the mounting section 120 has a front mounting section 122 and a rear mounting section 124.

[0028] The front attachment portion 122 is located in front of the opening forming portion S12. The front attachment portion 122 is formed in a position corresponding to at least the forefoot of a wearer of the shoe 1. The front attachment portion 122 is formed between the toe region R11 and the middle region R12.

[0029] As shown in FIGS. 8 and 9, the front mounting portion 122 has a plurality of partition plates 122a and a rail portion 122b.

[0030] Each partition plate 122a stands upright from the bottom 110 and extends in the foot width direction. The multiple partition plates 122a are arranged side by side at intervals in the foot length direction. As shown in Figures 7 and 8, the distance between a pair of partition plates 122a adjacent to each other in the foot length direction among the multiple partition plates 122a is set to a size that allows each additional part 200 to be placed between the pair of partition plates 122a.

[0031] The rail portion 122b is connected to the plurality of partition plates 122a. The rail portion 122b has a shape that extends in the leg length direction. The rail portion 122b has a shape that stands upright from the bottom portion 110. The height of the rail portion 122b may be greater than the height of each of the partition plates 122a.

[0032] The rear mounting portion 124 is located rearward of the front mounting portion 122. The rear mounting portion 124 is formed rearward of the intermediate region R12 that includes the opening forming portion S12. As shown in FIGS. 8 and 10, the rear mounting portion 124 has a back surface 124s, multiple partition plates 124a, and rail portions 124b.

[0033] The rear surface 124s stands upright from the bottom 110. The rear surface 124s is formed flat. The rear surface 124s is perpendicular to the bottom 110.

[0034] Each partition plate 124a has a shape that protrudes from the back surface 124s parallel to the bottom portion 110 and extends in the foot width direction. The multiple partition plates 124a are arranged so as to be spaced apart in the height direction. As shown in FIGS. 7, 8, and 10, the distance between a pair of partition plates 124a adjacent to each other in the height direction among the multiple partition plates 124a is set to a size that allows each additional part 200 to be placed between the pair of partition plates 124a. As shown in FIG. 10, the multiple partition plates 124a have a shape that gradually increases in length in the foot width direction as they approach the bottom portion 110.

[0035] The rail portion 124b is connected to the plurality of partition plates 124a. The rail portion 124b has a shape that extends in the height direction. The rail portion 124b has a shape that protrudes from the back surface 124s. The length of the rail portion 124b in the leg length direction may be the same as the length of each partition plate 124a in the same direction.

[0036] 7 to 10 and 15, the base part 100 has a first base member 100A and a second base member 100B. The second base member 100B is detachable from the first base member 100A. As shown in Fig. 15, the second base member 100B can be separated in the vertical direction from the first base member 100A.

[0037] The boundary between the first base member 100A and the second base member 100B is formed in the middle region R12, i.e., at a position that passes through the opening portion forming portion S12 in the height direction. The boundary extends in the height direction. The front attachment portion 122 is located in front of the boundary, and the rear attachment portion 124 is located behind the boundary. In other words, the first base member 100A has the front attachment portion 122, the toe region R11, and the front portion of the middle region R12, and the second base member 100B has the rear attachment portion 124 and the rear portion of the middle region R12.

[0038] 9 and 15, a first engagement portion 101 is formed at the rear end of the first base member 100A, and a second engagement portion 102 that engages with the first engagement portion 101 is formed at the front end of the second base member 100B. In this embodiment, the first engagement portion 101 is configured as a recessed groove extending in the height direction, and the second engagement portion 102 is configured as a convex shape that extends in the height direction and has a shape corresponding to the first engagement portion 101. However, the first engagement portion 101 may be configured as a convex shape, and the second engagement portion 102 may be configured as a recessed groove.

[0039] Fig. 11 is a diagram schematically showing a pattern in which a plurality of additional parts are arranged on a board. A plurality of additional parts 200 are cut out from the board B shown in Fig. 11. Of the plurality of additional parts 200 formed on the board B, the additional parts 200 marked with numbers are the additional parts 200 to be attached to the front mounting part 122, and the additional parts 200 marked with letters are the additional parts 200 to be attached to the rear mounting part 124. The pattern formed on the board B is set based on the last model LM.

[0040] Board B is made of, for example, medium density fiberboard (MDF). However, board B is not limited to MDF and may be made of other wood boards such as insulation fiberboard (IB) or hard fiberboard (HB). Examples of IB include class A insulation board, tatami board, and sheathing board. Examples of HB include standard board and tempered board. Alternatively, board B may be made of a material suitable for the additional part 200, such as highly recyclable cardboard, cork, metal, or thermoplastic resin.

[0041] The multiple additional parts 200 can be attached to the attachment portion 120 of the base part 100. Each additional part 200 is formed in a plate shape. When attached to the attachment portion 120 (the state shown in FIG. 7), the multiple additional parts 200 have a second molding surface S20 that defines a second region of the upper molding surface S1 that is different from the first region. The second region is a region where the difference in foot shape between wearers is relatively large. In this embodiment, the second region has a front region R21 that corresponds to the instep of the wearer's foot and a rear region R22 that corresponds to the heel of the wearer's foot.

[0042] Each additional part 200 has an end surface 202. The second molding surface S20 is made up of the end surfaces 202 of the multiple additional parts 200. The front region R21 is made up of the end surfaces 202 of the multiple additional parts 200 attached to the front mounting part 122, and the rear region R22 is made up of the end surfaces 202 of the multiple additional parts 200 attached to the rear mounting part 124.

[0043] As shown in FIGS. 12 to 14, each additional part 200 has an insertion hole 200h and a groove 204 formed therein.

[0044] The insertion hole 200h is a through-hole for inserting the connecting member 300. As shown in FIGS. 12 and 13, the connecting member 300 is inserted into each insertion hole 200h of the multiple additional parts 200, thereby connecting the multiple additional parts 200. The connecting member 300 is formed in a shape that extends linearly (rod-like). The connecting member 300 inserted into each additional part 200 attached to the front attachment part 122 is inserted into a recess 103 (see FIG. 9) formed in the toe region R11. The connecting member 300 inserted into each additional part 200 attached to the rear attachment part 124 is inserted into a recess 104 (see FIG. 10) formed in the bottom part 110.

[0045] The groove 204 has a shape that can receive the rail portions 122b, 124b. The groove 204 is formed on the outer peripheral surface of the additional part 200 on the end surface opposite to the end surface 202 that constitutes the second molding surface S20.

[0046] An upper molding material (pre-molding upper) made of a fiber sheet containing heat-shrinkable yarn is placed over the last 10 described above, and this is then heat-treated. As a result, the heat-shrinkable yarn contained in the upper molding material shrinks, forming an upper 3 that conforms to the upper molding surface S1 of the last 10.

[0047] Thereafter, the second base member 100B is moved upward relative to the first base member 100A, whereby the second base member 100B is separated from the first base member 100A, and the second base member 100B and the multiple additional parts 200 attached thereto are removed from the opening portion 3a of the upper 3. Subsequently, the first base member 100A and the multiple additional parts 200 attached thereto are removed from the opening portion 3a.

[0048] As explained above, with the last 10 of this embodiment, it is possible to easily form any second molding surface S20 by selecting the additional part 200 to be attached to the attachment portion 120 of the base part 100. Furthermore, because the base part 100 has the first base member 100A and the second base member 100B, after the upper 3 is molded using this last 10, by separating the second base member 100B from the first base member 100A, it becomes easy to remove the last 10 from the opening portion 3a of the upper 3.

[0049] Modifications of the above embodiment will now be described.

[0050] (First Modification) As shown in FIG. 16, the mounting portion 120 may be configured only with the front mounting portion 122 of the first base member 100A, and the second base member 100B may not have a rear mounting portion. In this case, the surface of the second base member 100B forms part of the first molding surface S10. In this example, the first region further includes a rear region R13 that defines a surface along the heel portion. In this example, the second base member 100B may be configured to be separable in the foot length direction.

[0051] (Second Modification) 17, the toe region R11 may be formed smaller than that in the above embodiment. In this example, the front attachment portion 122 extends forward in the foot length direction.

[0052] (Third Modification) 18, the second base member 100B may further have an intermediate mounting portion 126 located between the front mounting portion 122 and the rear mounting portion 124. In this example, the end surface 202 of each additional part 200 mounted on the intermediate mounting portion 126 also forms part of the second molding surface S20.

[0053] (Fourth Modification) As shown in FIG. 19, the rail portion 122b may be provided with a plurality of locking portions 122c arranged side by side in the foot length direction, and each additional part 200 may be provided with a pair of protrusions 206 that engage with the locking portions 122c. In the example shown in FIG. 19, each locking portion 122c is configured as a through-hole that penetrates the rail portion 122b in the foot width direction. The pair of protrusions 206 have a shape that protrudes in directions approaching each other from the inner surface of the groove portion 204. In this embodiment, each additional part 200 is prevented from coming off upward from the front attachment portion 122.

[0054] The above can also be applied to the rear mounting portion 124 and the additional part 200 mounted thereon.

[0055] (Fifth Modification) 20, each partition plate 122a may be provided with a protrusion 122d that protrudes in the leg length direction, and each additional part 200 may be provided with an engaging portion 208 that engages with the protrusion 122d. In the example shown in Fig. 20, the engaging portion 208 is configured as a through-hole that penetrates the additional part 200 in its thickness direction.

[0056] In this embodiment, the position of each additional part 200 relative to the first base member 100A in the foot width direction is effectively determined, and the upward detachment of each additional part 200 from the front attachment part 122 is suppressed.

[0057] The above can also be applied to the rear mounting portion 124 and the additional part 200 mounted thereon.

[0058] (Sixth Modification) As shown in FIG. 21, the bottom part 110 may be omitted from the second base member 100B, and the multiple additional parts 200 may include multiple vertical parts 210 and multiple horizontal parts 220.

[0059] The multiple vertical parts 210 include a central part 212 that has a shape that extends rearward from the rear surface of the second base member 100B. The central part 212 is connected to the back surface of the second base member 100B. The central part 212 has multiple grooves that are spaced apart in the height direction, and each groove has a shape that extends forward from the rear end of the central part 212.

[0060] Each lateral part 220 is positioned relative to the central part 212 by being inserted into a groove in the central part 212. Each lateral part 220 is provided with grooves extending radially.

[0061] Of the multiple vertical parts 210, parts other than the central part 212 are inserted into the grooves of the respective horizontal parts 220. Therefore, the multiple vertical parts 210 are arranged so as to be generally radial in plan view.

[0062] In this example, the rear region R22 is configured by the end faces of the plurality of vertical parts 210 and the end faces of the plurality of horizontal parts 220.

[0063] (Seventh Modification) As shown in Fig. 22, the last 10 may be provided with a cutout 10a for hooking the upper end of the upper molding material (the portion that becomes the shoe opening portion 3a). Note that in this example, the last 10 shown in Fig. 21 is provided with the cutout 10a, but the lasts 10 in the above-described embodiment and each of the above-described modified examples may also be provided with the cutout 10a.

[0064] (Eighth Modification) In the above embodiment, an example is shown in which each additional part 200 is created based on image data of the wearer's foot F, but a large number of additional parts 200 having various shapes may be prepared in advance, and one that is closest to the shape of the wearer's foot F may be selected from among them as appropriate.

[0065] (Ninth Modification) The last 10 described in the above embodiment may be used as a shoe keeper. In this case, the upper molding surface S1 of the last 10 functions as an upper holding surface that holds the shape of the upper 3 of the shoe 1. In other words, the last 10 described in the above embodiment functions as a molding component that can be used as both a last and a shoe keeper.

[0066] When the molding member is used as a shoe keeper, the configuration is as follows. That is, the shoe keeper comprises a base part including a bottom, and a plurality of additional parts, each formed in a plate shape and capable of being assembled to the base part. The base part has an attachment portion for attaching the plurality of additional parts so that the plurality of additional parts are arranged in multiple layers in one direction, and a first holding surface that defines a first region of the upper holding surface. The plurality of additional parts have a second holding surface that defines a second region of the upper holding surface that is different from the first region when attached to the attachment portion. Each of the plurality of additional parts has an end surface. The second molding surface is constituted by the end surface of each of the plurality of additional parts. The base part has a first base member including the attachment portion, and a second base member that is detachable from the first base member.

[0067] (Tenth Modification) 23 and 24, a portion of the bottom part 110 located below the front attachment part 122 may be omitted from the first base member 100A. In this case, each additional part 200 attached to the front attachment part 122 has a bottom end surface 203. The bottom end surface 203 of each of the multiple additional parts 200 attached to the front attachment part 122, together with the bottom part 110 of the base part 100, defines the bottom surface of the upper 3.

[0068] It will be appreciated by those skilled in the art that the exemplary embodiments described above are examples of the following aspects.

[0069] A last according to one aspect of this disclosure is a last having an upper molding surface that molds an upper having an opening portion, and comprises: a base part including a bottom portion that defines the bottom surface of the upper; and a plurality of additional parts, each formed in a plate shape and capable of being assembled to the base part; the base part has an attachment portion for attaching the plurality of additional parts so that the plurality of additional parts are arranged in multiple layers along one direction; and a first molding surface that defines a first region of the upper molding surface; the plurality of additional parts have second molding surfaces that, when attached to the attachment portion, define a second region of the upper molding surface that is different from the first region; each additional part in the plurality of additional parts has an end surface, and the second molding surface is constituted by the end surface of each of the plurality of additional parts; and the base part has a first base member including the attachment portion; and a second base member that is detachable from the first base member.

[0070] With this last, it is possible to easily form any second molding surface by selecting the additional part to be attached to the attachment portion of the base part. Furthermore, because the base part has a first base member and a second base member, after the upper is molded using this last, by separating the second base member from the first base member, it becomes easy to remove the last from the opening portion of the upper.

[0071] The first molding surface may include an opening forming portion that forms the opening, the attachment portion may include a front attachment portion located in front of the opening forming portion, and the first base member may include the front attachment portion. In this case, it is preferable that the boundary portion between the first base member and the second base member is formed at a position corresponding to the opening in the height direction.

[0072] In this embodiment, after the upper is molded, it is possible to separate the first base member and the second base member within the projected surface of the opening portion, making it easier to remove the last from the opening portion of the upper.

[0073] In this case, the front attachment portion may have a plurality of partition plates each standing upright from the bottom portion and extending in the foot width direction, and arranged at intervals in the foot length direction. The distance between a pair of partition plates adjacent to each other in the foot length direction is set to a size that allows each of the additional parts to be placed between the pair of partition plates.

[0074] In this embodiment, by arranging the additional parts between the pair of partition walls, the positions of the additional parts relative to the first base member in the foot length direction are effectively determined.

[0075] The front attachment section may further include a rail section that is connected to the plurality of partition plates and extends in the foot length direction. Each of the additional parts has a groove section that is shaped to receive the rail section.

[0076] In this aspect, by inserting the rail portion into the groove portion, the position of each additional part relative to the first base member in the foot width direction is effectively determined.

[0077] Each of the additional parts attached to the front attachment portion may have a bottom end surface, and the bottom end surface of each of the multiple additional parts attached to the front attachment portion, together with the bottom part of the base part, defines the bottom surface of the upper.

[0078] In this embodiment, it is not necessary to form a portion of the first base member that is located below the front attachment portion, which increases the degree of freedom in the shape of the bottom surface of the upper.

[0079] The mounting portion may further include a rear mounting portion located behind the boundary between the first base member and the second base member. In this case, it is preferable that the second base member includes the rear mounting portion.

[0080] In this embodiment, the rear portion of the upper can also be formed into any desired molding surface.

[0081] It should be noted that the embodiments disclosed herein are illustrative in all respects and should not be considered limiting. The scope of the present invention is defined by the claims, not by the description of the above embodiments, and further includes all modifications within the meaning and scope of the claims.
