Technical Field
[0001] This disclosure relates to a shoe last. Background Technology
[0002] In shoemaking, a shoe last (shoe mold) is used to cover the fabric that makes up the shoe upper in order to shape the shoe upper into a specified shape.
[0003] U.S. Patent Application Publication No. 2018 / 0014609 discloses the manufacture of footwear within a portable casing. U.S. Patent Application Publication No. 2016 / 0206049 discloses a shoe last preform that can be reshaped using shape memory polymers. Chinese Patent No. 109732913 discloses the formation of shoe lasts using 3D printing. Summary of the Invention
[0004] If the entire shoe last is custom-made to conform to the shape of the wearer's foot, the production process is time-consuming.
[0005] On the other hand, regarding the shape of the foot, it is known that there are parts with relatively small differences and parts with relatively large differences between each wearer. Therefore, by using unchanging (common) components to form the shape of the parts with relatively small differences between each wearer, and using variable (custom) components to form the shape of the parts with relatively large differences between each wearer, and by combining these components, it is relatively easy to form any shaped surface corresponding to the shape of the wearer's foot.
[0006] However, after the shoe upper is shaped using this type of last, there is a situation where it is difficult to remove the last from the shoe opening.
[0007] The purpose of this disclosure is to provide a shoe last that can be formed relatively easily with any shaped surface and is easy to remove from the shoe opening after the upper has been formed.
[0008] One aspect of this disclosure is a shoe last having a shoe upper forming surface, the shoe upper forming surface shaping a shoe upper having a shoe opening portion, comprising: a base component including a bottom portion defining the bottom surface of the shoe upper; and a plurality of additional components, each formed as a plate and assembleable to the base component, the base component having: a mounting portion for mounting the plurality of additional components in a multi-layered manner arranged in one direction; and a first forming surface defining a first region in the shoe upper forming surface, the plurality of additional components having a second forming surface, the second forming surface defining a second region in the shoe upper forming surface different from the first region when mounted to the mounting portion, each of the plurality of additional components having an end face, the second forming surface including each of the end faces of the plurality of additional components, the base component having: a first base member including the mounting portion; and a second base member detachable relative to the first base member.
[0009] The described and other objects, features, aspects and advantages of the invention will become apparent from the following detailed description relating to the invention in conjunction with the accompanying drawings. Attached Figure Description

[0034] Embodiments of the present invention will be described with reference to the accompanying drawings. Furthermore, in the drawings referred to below, identical or equivalent components are labeled with the same numbers. In the following description, terms such as foot length direction, foot width direction, front, and rear are used. These directional terms indicate the direction viewed from the perspective of a wearer wearing shoes 1 placed on a flat surface such as the ground. For example, "front" refers to the toe side, and "rear" refers to the heel side.
[0035] Figure 1 This is a perspective view of a shoe made using the shoe last according to one embodiment of the present disclosure. Figure 2 yes Figure 1 A cross-sectional view along line II-II in the diagram. Figure 3 It's an exploded 3D diagram of the shoe. In addition, Figures 1-3 The image shows a shoe 1 for the left foot, but the shoe 1 can also be used for the right foot. The shoe for the right foot has a shape that is symmetrical to or substantially symmetrical to the shoe 1 for the left foot. The shoe 1 can be used, for example, as a running shoe or a walking shoe, and its use is not limited.
[0036] like Figures 1-3 As shown, shoe 1 includes sole 2, upper 3, and shell 4.
[0037] The sole 2 is formed of a resin-based foam material or the like. An upper 3 is disposed on the sole 2. The upper 3 forms the part that contacts the wearer's foot and includes a bag-like component that can be flexibly deformed. The upper 3 includes a fiber sheet containing heat-shrinkable yarn. The upper 3 has an opening 3a.
[0038] The shoe shell 4 houses the sole 2 and the upper 3. The shoe shell 4 constitutes the outermost shell of the shoe 1 and includes a single flexible component formed in a bag shape. The shoe shell 4 covers the bottom surface of the sole 2 and the surface of the upper 3.
[0039] Figure 4 This diagram illustrates the process of photographing the wearer's foot (F) to obtain a foot model (FM). For example... Figure 4 As shown, the image data of the wearer's foot (F) is obtained by using a portable device such as a smartphone (P) or a digital camera. The image data of the foot (F) can also be taken in a store visited by the wearer. The store can be a fixed store or a mobile store using a car or trailer. Alternatively, the image data of the foot (F) can be taken at the wearer's own home. The image data of the foot (F) obtained by the wearer can be sent to the shoe manufacturer's server.
[0040] Figure 5 It is a 3D model of the foot shape FM. Figure 5The foot model FM shown is a three-dimensional foot model generated based on measurement data of various parts of the wearer's foot F obtained from image data of the foot F. For example, if the wearer's foot F is photographed using 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 can be generated by performing calculations using the photographed image data and data from a server used by the shoe manufacturer.
[0041] The foot model FM can be formed to match the shape of the wearer's foot F. Alternatively, based on design or functional reasons, specific parts of the foot model FM can be modified to the required size relative to the shape of the wearer's foot F.
[0042] Figure 6 It is a 3D model of the shoe last (LM). Figure 6 The shoe last model LM shown is based on Figure 5 The foot model FM shown is a model of a shoe last custom-made according to the shape of the wearer's foot F. A shoe last 10 (see reference) is made using the shoe last model LM. Figure 7 The upper 3 is shaped to create custom shoes 1 specifically for the wearer.
[0043] Figure 7 This is a perspective view of a shoe last according to one embodiment of the present disclosure, made based on a shoe last model. The shoe last 10 has an upper forming surface S1 for forming the upper 3. The shoe last 10 includes a base component 100, a plurality of additional components 200, and a connecting structural component 300 (see reference). Figures 12-14 ).
[0044] The base component 100 includes materials such as resin or wood, metal, or a cured slurry. For example... Figure 8 As shown, the base component 100 has a bottom 110, a mounting portion 120, and a first forming surface S10.
[0045] The bottom 110 defines the bottom surface of the upper 3. The bottom 110 is formed as a flat plate. The bottom 110 has a shape that extends from the rear end of the upper forming surface S1 to the front end.
[0046] The first forming surface S10 defines a first region in the shoe upper forming surface S1. The first region is a region where the differences in the shape of each wearer's foot are relatively small. In this embodiment, the first region has a toe region R11 and a middle region R12.
[0047] The toe area R11 is the area that forms the part of the upper 3 that covers the toe of the wearer. The toe area R11 is formed at the front end of the bottom 110.
[0048] The intermediate region R12 is the area that forms the middle part of the wearer's foot in the length direction of the foot in the upper 3. The middle part is the part that coincides with the wearer's ankle in the height direction. That is, the intermediate region R12 is the area below the shoe opening 3a in the upper 3. The intermediate region R12 includes the shoe opening forming part S12 that forms the shoe opening 3a.
[0049] The mounting section 120 is a part used to mount multiple additional components 200 in a multi-layered manner arranged in one direction. For example... Figures 8-10 As shown, the mounting section 120 has a front mounting section 122 and a rear mounting section 124.
[0050] The front mounting portion 122 is located in front of the shoe opening forming portion S12. The front mounting portion 122 is formed on the shoe 1 at a position corresponding to at least the forefoot of the wearer. The front mounting portion 122 is formed between the toe area R11 and the middle area R12.
[0051] like Figure 8 and Figure 9 As shown, the front mounting section 122 has multiple spacers 122a and a track section 122b.
[0052] Each spacer plate 122a has a shape that stands upright from the bottom 110 and extends along the width of the foot. The multiple spacer plates 122a are arranged in a spaced-apart configuration along the length of the foot. Figure 7 and Figure 8 As shown, the distance between a pair of adjacent spacers 122a along the leg length direction is set to a size that allows each additional component 200 to be arranged between the pair of spacers 122a.
[0053] The track section 122b is connected to a plurality of spacers 122a. The track section 122b has a shape that extends along the length of the legs. The track section 122b has a shape that stands upright from the bottom 110. The height of the track section 122b may be greater than the height of each spacer 122a.
[0054] The rear mounting portion 124 is located behind the front mounting portion 122. The rear mounting portion 124 is formed behind the intermediate region R12, including the shoe opening portion S12. For example... Figure 8 and Figure 10 As shown, the rear mounting part 124 has a back surface 124s, multiple spacers 124a, and a track part 124b.
[0055] The back side 124s stands upright from the bottom 110. The back side 124s is formed flat. The back side 124s is perpendicular to the bottom 110.
[0056] Each spacer plate 124a has a shape that protrudes parallel to the bottom 110 from the back side 124s and extends along the width direction of the foot. The multiple spacer plates 124a are arranged in a spaced-apart configuration along the height direction. Figure 7 , Figure 8 and Figure 10 As shown, the distance between a pair of adjacent spacers 124a in the height direction is set to a size that allows for the arrangement of each additional component 200 between the pair of spacers 124a. Figure 10 As shown, the multiple spacers 124a have a shape in which the length in the foot width direction gradually increases as they approach the bottom 110.
[0057] The track section 124b is connected to a plurality of spacers 124a. The track section 124b has a shape that extends along the height direction. The track section 124b has a shape that protrudes from the back side 124s. The length of the track section 124b in the leg length direction may be the same as the length of each spacer 124a in the same direction.
[0058] like Figures 7-10 and Figure 15 As shown, the base component 100 has a first base member 100A and a second base member 100B. The second base member 100B is detachable relative to the first base member 100A. Figure 15 As shown, the second base component 100B can be divided in the vertical direction relative to the first base component 100A.
[0059] The boundary between the first base member 100A and the second base member 100B is formed in the intermediate region R12, that is, at a position that passes through the shoe opening forming portion S12 in the height direction. The boundary extends along the height direction. The front mounting portion 122 is located in front of the boundary portion, and the rear mounting portion 124 is located behind the boundary portion. That is, the first base member 100A has a front mounting portion 122, a toe region R11, and a front portion of the intermediate region R12, and the second base member 100B has a rear mounting portion 124 and a rear portion of the intermediate region R12.
[0060] like Figure 9 and Figure 15 As shown, a first engaging portion 101 is formed at the rear end of the first base member 100A, and a second engaging portion 102 that engages with the first engaging portion 101 is formed at the front end of the second base member 100B. In this embodiment, the first engaging portion 101 includes a groove extending along the height direction, and the second engaging portion 102 includes a convex shape extending along the height direction and having a shape corresponding to the first engaging portion 101. However, the first engaging portion 101 may also include a convex shape, and the second engaging portion 102 may include a groove.
[0061] Figure 11 This is a schematic diagram showing a pattern of multiple additional components arranged on a board. The multiple additional components 200 are... Figure 11 Cut from the shown plate B. Among the multiple additional parts 200 formed on plate B, the additional parts 200 marked with numbers are those installed on the front mounting part 122, and the additional parts 200 marked with letters are those installed on the rear mounting part 124. Furthermore, the pattern formed on plate B is based on the shoe last model LM.
[0062] Board B may include, for example, medium-density fiberboard (MDF). However, board B is not limited to MDF and may also include other wood-based panels such as insulation fiberboard (IB) or hard fiberboard (HB). Examples of IB include: Class A insulation board, tatami board, or sheathing board. Examples of HB include standard board or tough board. Alternatively, board B may be formed from materials suitable for additional component 200, such as highly recyclable cardboard or cork, metal, or thermoplastic resin.
[0063] Multiple additional components 200 can be mounted on the mounting portion 120 of the base component 100. Each additional component 200 is formed in the shape of a plate. The multiple additional components 200 are in a state of being mounted on the mounting portion 120. Figure 7 The second forming surface S20, which defines a second region in the shoe upper forming surface S1 that differs from the first region, is shown in the state described. The second region is the region where the shape of each wearer's foot varies relatively greatly. In this embodiment, the second region has a front region R21 corresponding to the instep of the wearer and a rear region R22 corresponding to the heel of the wearer.
[0064] Each additional component 200 has an end face 202. The second forming surface S20 includes the end faces 202 of the multiple additional components 200. The front region R21 includes the end faces 202 of the multiple additional components 200 mounted on the front mounting portion 122, and the rear region R22 includes the end faces 202 of the multiple additional components 200 mounted on the rear mounting portion 124.
[0065] like Figures 12-14 As shown, each additional component 200 has an insertion hole 200h and a groove 204 formed thereon.
[0066] The 200h through hole is a through hole used to insert the 300 connecting structural component. For example... Figure 12 and Figure 13As shown, the connecting member 300 connects the multiple additional members 200 by inserting through holes 200h into each of the multiple additional members 200. The connecting member 300 is formed in a straight-line extending shape (rod-shaped). The connecting member 300, which is inserted into each of the additional members 200 mounted on the front mounting portion 122, is inserted into the recess 103 formed in the toe region R11 (see reference). Figure 9 The connecting member 300, which passes through each of the additional components 200 installed in the rear mounting part 124, is inserted into the recess 104 formed in the bottom 110 (see reference). Figure 10 ).
[0067] The groove 204 has a shape that can receive the track section 122b and the track section 124b. The groove 204 is formed on the end face opposite to the end face 202 that constitutes the second forming surface S20 in the outer peripheral surface of the auxiliary member 200.
[0068] An upper forming material (the upper before forming) comprising a fiber sheet containing protective heat-shrinkable yarn is wrapped over the shoe last 10 described above, and then subjected to heat treatment. As a result, the heat-shrinkable yarn contained in the upper forming material shrinks, thus forming the upper 3 along the upper forming surface S1 of the shoe last 10.
[0069] Then, the second base member 100B is moved upward relative to the first base member 100A, thereby separating the second base member 100B from the first base member 100A, and removing the second base member 100B and the plurality of additional components 200 mounted thereon from the shoe opening 3a of the upper 3. Next, the first base member 100A and the plurality of additional components 200 mounted thereon are removed from the shoe opening 3a.
[0070] As explained above, in the shoe last 10 of this embodiment, any second forming surface S20 can be easily formed by selecting the additional component 200 of the mounting portion 120 installed in the base component 100. Furthermore, since the base component 100 has a first base member 100A and a second base member 100B, after the upper 3 is formed using the shoe last 10, the second base member 100B is separated from the first base member 100A, thereby making it easy to remove the shoe last 10 from the shoe opening portion 3a of the upper 3.
[0071] The following describes variations of the embodiments.
[0072] (First variation)
[0073] like Figure 16As shown, the mounting portion 120 may only include 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 forming surface S10. In this example, the first region also includes a rear region R13 defined along the surface of the heel portion. Furthermore, in this example, the second base member 100B may be configured in a way that allows it to be divided along the leg length direction.
[0074] (Second variation)
[0075] like Figure 17 As shown, the toe region R11 can be formed in a manner smaller than the toe region R11 in the described embodiment. In this example, the front mounting portion 122 extends forward in the foot length direction.
[0076] (Third variation)
[0077] like Figure 18 As shown, 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 the example described, the end faces 202 of each additional component 200 mounted on the intermediate mounting portion 126 also constitute part of the second forming surface S20.
[0078] (Fourth variation)
[0079] like Figure 19 As shown, a plurality of locking portions 122c may be provided on the track portion 122b in a manner arranged along the length of the leg, and a pair of protrusions 206 that engage with the locking portions 122c may be provided on each additional component 200. Figure 19 In the example shown, each locking portion 122c includes a through hole extending through the track portion 122b along the width of the foot. A pair of protrusions 206 have a shape that protrudes from the inner side of the groove portion 204 in a direction toward each other. In this configuration, the upward disengagement of each additional component 200 from the front mounting portion 122 is suppressed.
[0080] The above situation can also be applied to the rear mounting section 124 and the additional components 200 mounted thereon.
[0081] (Fifth variation)
[0082] like Figure 20 As shown, each spacer 122a may have a protrusion 122d extending along the leg length direction, and each additional component 200 may have an engaging portion 208 that engages with the protrusion 122d. Figure 20 In the example shown, the engaging portion 208 includes a through hole extending through the additional member 200 along the thickness direction of the additional member 200.
[0083] In the described configuration, the position of each additional component 200 in the foot width direction relative to the first base member 100A can be effectively determined, and the disengagement of each additional component 200 from the front mounting portion 122 upward is suppressed.
[0084] The above situation can also be applied to the rear mounting section 124 and the additional components 200 mounted thereon.
[0085] (Sixth variation)
[0086] like Figure 21 As shown, the second base component 100B to the bottom 110 may also be omitted, and multiple vertical components 210 and multiple horizontal components 220 may be included as multiple additional components 200.
[0087] The plurality of longitudinal members 210 include a central member 212 having a shape extending rearward from the rear surface of the second base member 100B. The central member 212 is connected to the back side of the second base member 100B. A plurality of slots are formed in the central member 212 at intervals along the height direction, each slot having a shape extending forward from the rear end of the central member 212.
[0088] Each horizontal member 220 is positioned relative to the central member 212 by being inserted into a slot in the central member 212. Each horizontal member 220 is provided with a radially extending slot.
[0089] The components of the plurality of longitudinal components 210, excluding the central component 212, are inserted into the slots of each transverse component 220. Thus, the plurality of longitudinal components 210 are arranged in a generally radial manner when viewed from above.
[0090] In the example, the rear region R22 includes each end face of a plurality of longitudinal members 210 and each end face of a plurality of transverse members 220.
[0091] (Seventh variation)
[0092] like Figure 22 As shown, a notch 10a can be provided on the shoe last 10 for hooking the upper forming material (the portion that becomes the shoe opening 3a). Furthermore, in the example described, a notch 10a is shown in the shoe last 10 for hooking the upper forming material. Figure 21 The shoe last 10 shown has a notch 10a, but the shoe last 10 in the embodiment or the various modifications may also have a notch 10a.
[0093] (Eighth variation)
[0094] In the described embodiment, an example is shown where each of the additional components 200 is made based on image data of the wearer’s foot F, but a large number of additional components 200 with various shapes can also be prepared in advance, from which components that are close to the shape of the wearer’s foot F can be appropriately selected.
[0095] (Ninth variation)
[0096] The shoe last 10 described in the embodiment can be used as a shoe support. In this case, the upper forming surface S1 of the shoe last 10 functions as an upper retaining surface that maintains the shape of the upper 3 in the shoe 1. That is, the shoe last 10 described in the embodiment functions as a mold component that can be used as both a shoe last and a shoe support.
[0097] The structure of the molded component used as a shoe tree is as follows. That is, the shoe tree includes: a base component including a bottom; and a plurality of additional components, each formed in a plate shape and capable of being assembled to the base component. The base component has: a mounting portion for mounting the plurality of additional components in a multi-layered manner arranged in one direction; and a first retaining surface defining a first region of the shoe upper retaining surface. The plurality of additional components have a second retaining surface, which, when mounted to the mounting portion, defines a second region of the shoe upper retaining surface different from the first region. Each of the plurality of additional components has an end face. The second forming surface includes the end face of each of the plurality of additional components. The base component has: a first base member including the mounting portion; and a second base member detachable relative to the first base member.
[0098] (Tenth variation)
[0099] like Figure 23 and Figure 24 As shown, the portion of the first base member 100A located below the front mounting portion 122 in the bottom 110 can be omitted. In this case, each additional member 200 mounted on the front mounting portion 122 has a bottom end face 203. The bottom end face 203 of each of the plurality of additional members 200 mounted on the front mounting portion 122, together with the bottom 110 of the base member 100, defines the bottom surface of the upper 3.
[0100] Those skilled in the art will understand that the plurality of exemplary embodiments are specific examples of the following forms.
[0101] One aspect of this disclosure is a shoe last having a shoe upper forming surface, the shoe upper forming surface forming a shoe upper having a shoe opening portion, and comprising: a base component including a bottom portion defining the bottom surface of the shoe upper; and a plurality of additional components, each formed as a plate and capable of being assembled to the base component, the base component having: a mounting portion for mounting the plurality of additional components in a multi-layered manner arranged in one direction; and a first forming surface defining a first region in the shoe upper forming surface, the plurality of additional components having a second forming surface, the second forming surface defining a second region in the shoe upper forming surface different from the first region when mounted to the mounting portion, each of the plurality of additional components having an end face, the second forming surface including each of the end faces of the plurality of additional components, the base component having: a first base member including the mounting portion; and a second base member detachable relative to the first base member.
[0102] In the shoe last, any second shaped surface can be easily formed by selecting additional components installed in the mounting portion of the base component. Furthermore, since the base component has a first base member and a second base member, after the shoe upper is formed using the shoe last, the second base member can be separated from the first base member, thereby making it easy to remove the shoe last from the shoe opening of the shoe upper.
[0103] Furthermore, the first forming surface may include a shoe opening forming portion, which forms the shoe opening, and the mounting portion may include a front mounting portion located in front of the shoe opening forming portion, and the first base member may include the front mounting portion. In this case, it is preferable that the boundary between the first base member and the second base member is formed at a position in the height direction corresponding to the shoe opening.
[0104] In the described configuration, after the upper is formed, the first base component and the second base component can be separated within the projection plane of the shoe opening, making it easier to remove the shoe last from the shoe opening of the upper.
[0105] In this case, the front mounting portion may have multiple spacers, each of which stands upright from the bottom and has a shape extending along the width of the foot, and is arranged at intervals along the length of the foot. The distance between a pair of spacers that are adjacent to each other along the length of the foot is set to a size that allows each additional component to be arranged between the pair of spacers.
[0106] In this configuration, by arranging additional components between a pair of spacers, the position of each additional component relative to the first base member in the leg length direction can be effectively determined.
[0107] Furthermore, the front mounting portion may also include a track portion connected to the plurality of spacers, having a shape extending along the leg length direction. Each of the additional components has a groove formed in a shape capable of receiving the track portion.
[0108] In this configuration, by inserting a track portion into the groove, the position of each additional component in the foot width direction relative to the first base member can be effectively determined.
[0109] Furthermore, each of the additional components mounted on the front mounting portion may have a bottom end face. The bottom end face of each of the plurality of additional components mounted on the front mounting portion, together with the bottom of the base component, defines the bottom surface of the shoe upper.
[0110] In this configuration, it is not necessary to form the portion of the first basic component located below the front mounting portion, thus increasing the freedom of shape for the bottom surface of the shoe upper.
[0111] Furthermore, the mounting portion may also include a rear mounting portion, which is 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.
[0112] In this configuration, the rear of the shoe upper can also be formed into any shaped surface.
