The cushion part 60 has a thickness corresponding to the part,
The inner skin 40, the outer skin 50, and the cushion portion 60 are laminated in a majority of the upper 3 and integrated with each other.
　本アッパーのクッション部は部位に応じた厚さを有し、そのため、足沿いが良好となるだろう。
　また、内皮、外皮およびクッション部がアッパーの大半において積層されており、したがって、一つの連なった内皮やクッション部を実現できるだろう。そのため、違和感のない足沿いが得られるだろう。 The cushion portion of the upper will have a thickness depending on the site, so that it will be good along the foot.
In addition, the inner skin, outer skin, and cushion portion are laminated in most of the upper, so that one continuous inner skin and cushion portion could be realized. Therefore, you will be able to get along the foot without any sense of incongruity.
　本発明の製造方法は、前記内皮材４と前記外皮材５と前記フォーム材６とを重ねて貼り合わせ積層体７を得る積層工程と、
第１金型と第２金型との間に積層体７を装着する装着工程と、
前記第１金型と前記第２金型とを型締めする型締工程と、
前記型締めした状態で、前記内皮４０、外皮５０およびフォーム材６を所定の温度で加熱し前記フォーム材６が前記部位に応じた厚さとなるように前記積層体７を成型して成形体８を得る成型工程と、
前記第１および第２金型を型開きして前記成形体８を取り出す工程と、
前記成形体８から不要部分８０を除去する工程とを備える。 The production method of the present invention includes a laminating step in which the endothelium material 4, the outer skin material 5, and the foam material 6 are laminated to obtain a laminated body 7,
A mounting step of mounting the laminate 7 between the first mold and the second mold;

In the clamped state, the inner skin 40, the outer skin 50, and the foam material 6 are heated at a predetermined temperature to mold the laminate 7 so that the foam material 6 has a thickness corresponding to the portion. A molding process to obtain
Opening the first and second molds and taking out the molded body 8; and
A step of removing the unnecessary portion 80 from the molded body 8.
　本方法においては、内皮材、外皮材およびフォーム材を貼り合わせ積層体を得た後に、この積層体を加熱してプレス成型する。そのため、立体成型の工程を機械化することができる。したがって、立体成型するための熟練を要しない。また、工程が単純化される。 In this method, after a laminated body is obtained by laminating an endothelial material, a skin material and a foam material, the laminated body is heated and press-molded. Therefore, the three-dimensional molding process can be mechanized. Therefore, skill for three-dimensional molding is not required. In addition, the process is simplified.
　ここで、所定の温度とは、金型等の温度を制御するコントローラ等で設定される温度を意味し、例えば少なくともフォーム材が軟化する温度が好ましく、内皮、外皮およびフォーム材が軟化する温度が更に好ましく、これらが融解しない程度の温度に設定されるであろう。また、所定の温度で素材の表面や端部などの一部が融解してもよい。更に、例えばフォーム材の融点以上の温度に設定されてもよい。前記所定の温度とは所定の温度の範囲であることを意味する。すなわち、温度の管理や測定は金型の温度を前記所定の温度に保つことでなされ、したがって、所定の温度か否かは、プレス機のコントローラの表示などから知ることができるだろう。 Here, the predetermined temperature means a temperature set by a controller or the like that controls the temperature of a mold or the like. For example, a temperature at which the foam material is softened is preferable, and a temperature at which the endothelium, outer skin, and foam material are softened More preferably, the temperature will be set so that they do not melt. In addition, a part of the surface or edge of the material may melt at a predetermined temperature. Further, for example, the temperature may be set to a temperature equal to or higher than the melting point of the foam material. The predetermined temperature means a predetermined temperature range. That is, temperature management and measurement are performed by keeping the temperature of the mold at the predetermined temperature. Therefore, whether or not the temperature is the predetermined temperature can be known from the display of the controller of the press machine.

In the first laminated body 71, the outer skin material 5 and the first inner skin material 41 are laminated on the outer surface and the inner surface of the base 71b via an adhesive (adhesive layer) not shown. The base 71b may be made of a foam material.
前記第２積層体７２はアッパーの概ね後半部に設けられる。この第２積層体７２はベースとなる主フォーム材６１の内表面に第２内皮材４２が図示しない粘着剤を介して積層されている。なお、主フォーム材６１の外表面側には図示しない布帛材が設けられてもよい。 The second laminated body 72 is provided in a substantially second half portion of the upper. In the second laminate 72, the second endothelial material 42 is laminated on the inner surface of the main foam material 61 serving as a base via an adhesive (not shown).

前記外皮材５、第１内皮材４１、第２内皮材４２および布帛材は、プレスによる立体成型を容易にするために、熱により軟化する素材が採用される。また、前記各フォーム材としては、熱可塑性樹脂の発泡体が採用される。 The outer skin material 5, the first inner skin material 41, the second inner skin material 42 and the fabric material are made of materials that soften by heat in order to facilitate three-dimensional molding by pressing. As each foam material, a thermoplastic resin foam is employed.
前記積層工程の後に孔明工程が実行される。この孔明工程では、図４の装着工程に先立って予め前記積層体７に前記ピン１Ｐに合致する複数の貫通孔７ｈを設ける。 A drilling process is performed after the laminating process. In this drilling step, a plurality of through holes 7h that match the pins 1P are provided in advance in the laminate 7 prior to the mounting step of FIG.
つぎに、図４および図５のように、オス型１とメス型２との間に積層体７を装着する装着工程を実行する。
前記装着工程において前記複数の貫通孔７ｈを前記ピン１Ｐに挿通する。 Next, as shown in FIGS. 4 and 5, a mounting process for mounting the laminate 7 between the male mold 1 and the female mold 2 is executed.
In the mounting step, the plurality of through holes 7h are inserted through the pins 1P.
前記装着工程の後に図６および図７に示す型締工程を実行する。型締工程においては、前記アッパーの履き口を定義する縁部３０およびアッパーの下端の外周囲３１において、前記積層体７のフォーム材６の厚さが薄くなるように前記オス型１とメス型２とが型締される。
なお、アッパーの外周囲３１とは、たとえば、図２Ａおよび図２Ｂに示すように、足裏の周囲に沿って一周して延びるアッパー３の下端縁であってもよい。また、前記縁部３０は履き口の周りにおいてエンドレスのループを形成していてもよい。 After the mounting process, a mold clamping process shown in FIGS. 6 and 7 is performed. In the mold clamping step, the male mold 1 and the female mold are formed so that the thickness of the foam material 6 of the laminate 7 is reduced at the edge 30 defining the upper mouth and the outer periphery 31 of the lower end of the upper. 2 is clamped.
The upper outer periphery 31 may be, for example, the lower end edge of the upper 3 that extends around the sole as shown in FIGS. 2A and 2B. Further, the edge portion 30 may form an endless loop around the mouth.
図７において、前記型締工程の後に、前記内皮４０、外皮５０およびフォーム材６を所定の温度（例えば１６０°～１８０°程度）で所持時間（１５０ｓｅｃ～２５０ｓｅｃ）加熱し前記フォーム材６が前記部位に応じた厚さとなるように前記積層体７を成型して成形体８（図８）が得られる。前記メス型２には前記オス型ベース１１に向かって突出する切断部２２（図５）が設けられている。前記切断部２２がオス型ベース１１に当接ないし近接することで、前記アッパーの下端の外周囲３１において成形体８が薄く、かつ、脆くなる。
前記型締工程において、図５～図７に示すように、前記内皮材４、外皮材５およびフォーム材６は一対の金型１，２の歯合動作時に前記足型部１０および凹所２１の形状に沿って伸びるように変形される。また、前記型締工程の後に前記内皮材４、外皮材４およびフォーム材６は図７の一対の金型１，２からの伝熱により金型１，２の間のキャビティ内で昇温し軟化する。これにより、前記内外皮４，５およびフォーム材６は、元の形状に復元する応力を失いながら、同キャビティの形状に応じた形状や厚みとなる。前記内外皮４，５およびフォーム材６は、後に冷却されて、前記形状や厚みが維持される。なお、例えば前記フォーム材６の少なくとも一部が融解されてもよい。この場合、融解された前記フォーム材は元の形状に復元することなく所期の形状を得やすいだろう。また、同フォーム材は内外皮材に対しアンカー効果により固く付着されるだろう。 In FIG. 7, after the mold clamping step, the inner skin 40, the outer skin 50 and the foam material 6 are heated at a predetermined temperature (for example, about 160 ° to 180 °) for a holding time (150 sec to 250 sec), so that the foam material 6 The laminated body 7 is molded so as to have a thickness corresponding to the part to obtain a molded body 8 (FIG. 8). The female die 2 is provided with a cutting portion 22 (FIG. 5) that protrudes toward the male base 11. When the cutting portion 22 is in contact with or close to the male base 11, the molded body 8 is thin and fragile in the outer periphery 31 at the lower end of the upper.
In the mold clamping step, as shown in FIGS. 5 to 7, the inner skin material 4, the outer skin material 5, and the foam material 6 are used for the foot mold portion 10 and the recess 21 when the pair of molds 1 and 2 are engaged. It is deformed so as to extend along the shape. Further, after the mold clamping step, the inner skin material 4, the outer skin material 4 and the foam material 6 are heated in the cavity between the molds 1 and 2 by heat transfer from the pair of molds 1 and 2 in FIG. Soften. Thus, the inner and outer skins 4 and 5 and the foam material 6 have a shape and thickness corresponding to the shape of the cavity while losing the stress to restore the original shape. The inner and outer skins 4 and 5 and the foam material 6 are later cooled to maintain the shape and thickness. For example, at least a part of the foam material 6 may be melted. In this case, the melted foam material will easily obtain the desired shape without restoring the original shape. Also, the foam material will adhere firmly to the inner and outer skin materials due to the anchor effect.
次に、図８の前記オス型１およびメス型２を型開きして前記成形体８が取り出される。その後、図９Ａの前記縁部３０および外周囲３１の薄くなった部位において前記積層体７が切断されて前記成形体８から不要部分８０が除去される。
たとえば、前記不要部分８０の１つはアッパーの履き口および開口（前記履き口に連なり舌片で覆われる）に相当する箇所の部分であり、残部は前記外周囲３１よりも外の部分である。 Next, the male mold 1 and the female mold 2 in FIG. 8 are opened, and the molded body 8 is taken out. Thereafter, the laminated body 7 is cut at the thinned portions of the edge 30 and the outer periphery 31 in FIG. 9A, and the unnecessary portion 80 is removed from the molded body 8.
For example, one of the unnecessary portions 80 is a portion corresponding to an upper wear mouth and an opening (continuous to the wear mouth and covered with a tongue piece), and the remaining portion is a portion outside the outer periphery 31. .
その後、図９Ｂの前記成形体８に中底１００が取り付けられてアッパー３が生成される。たとえば、中底１００の周囲をアッパーの外周囲３１に縫合してアッパー３が生成される。 Thereafter, the insole 100 is attached to the molded body 8 of FIG. 9B, and the upper 3 is generated. For example, the upper 3 is generated by sewing the periphery of the insole 100 to the outer periphery 31 of the upper.

The female base 21 is provided with a plurality of guide holes 2h through which the pins 1P penetrate.
つぎに、実施例２のアッパーの製造方法が説明される。 Next, an upper manufacturing method according to the second embodiment will be described.
図１２Ａ～図１２Ｃに示すように、積層工程において、図１２Ｂの前記内皮材４および前記外皮材５と前記フォーム材６とを重ねて貼り合わせ図１２Ｃの積層体７を得る。この積層体７の構造の一例について詳述する。 As shown in FIGS. 12A to 12C, in the laminating step, the inner skin material 4 and the outer skin material 5 of FIG. 12B are overlapped with the foam material 6 to obtain a laminated body 7 of FIG. 12C. An example of the structure of the laminate 7 will be described in detail.
図１２Ｂに示すように、前記積層体７は内外一対の第１積層体７１と第２積層体７２との間に内外一対の補助フォーム材６２がサンドイッチされた状態で積層される。 As shown in FIG. 12B, the laminated body 7 is laminated in a state where a pair of inner and outer auxiliary foam materials 62 are sandwiched between a pair of inner and outer first laminated bodies 71 and a second laminated body 72.
内足および外足の各第１積層体７１は、それぞれ爪先から踵までの概ね全域にわたって設けられている。この第１積層体７１はベース７１ｂの外表面に下地材９が図示しない粘着剤（粘着層）を介して積層されている。 Each 1st laminated body 71 of an inner leg and an outer leg is provided over substantially the whole region from a toe to a heel, respectively. In the first laminated body 71, the base material 9 is laminated on the outer surface of the base 71b via an adhesive (adhesive layer) not shown.
前記第２積層体７２はベースとなる主フォーム材６１の内表面に内皮材４が図示しない粘着剤を介して積層されている。なお、主フォーム材６１の外表面側には図示しない布帛材が設けられてもよい。 In the second laminated body 72, the endothelial material 4 is laminated on the inner surface of the main foam material 61 serving as a base via an adhesive (not shown). A fabric material (not shown) may be provided on the outer surface side of the main foam material 61.
前記外皮材５、内皮材４および下地材９は、プレスによる立体成型を容易にするために、熱により軟化する素地が採用される。また、前記各フォーム材としては、熱可塑性樹脂の発泡体が採用される。 The outer skin material 5, the inner skin material 4 and the base material 9 are made of a base material that is softened by heat in order to facilitate three-dimensional molding by pressing. As each foam material, a thermoplastic resin foam is employed.
この例の場合、前記第１積層体７１、補助フォーム材６２および第２積層体７２の外表面側には、外皮材５が積層される。こうして、フォーム材６１，６２の外表面には外皮材５が積層され、内表面には内皮材４が積層される。 In this example, the outer skin material 5 is laminated on the outer surface side of the first laminated body 71, the auxiliary foam material 62 and the second laminated body 72. Thus, the outer skin material 5 is laminated on the outer surface of the foam materials 61 and 62, and the inner skin material 4 is laminated on the inner surface.
前記積層工程の後に孔明工程が実行される。この孔明工程では、図１５の装着工程に先立って図１４の前記積層体７に前記ピン１Ｐに合致する複数の貫通孔７ｈを設ける。 A drilling process is performed after the laminating process. In this drilling step, a plurality of through holes 7h that match the pins 1P are provided in the laminate 7 in FIG. 14 prior to the mounting step in FIG.
つぎに、図１４および図１５のように、オス型１とメス型２との間に積層体７を装着する装着工程を実行する。
前記装着工程において前記複数の貫通孔７ｈを前記ピン１Ｐに挿通する。 Next, as shown in FIGS. 14 and 15, a mounting process of mounting the laminate 7 between the male mold 1 and the female mold 2 is executed.
In the mounting step, the plurality of through holes 7h are inserted through the pins 1P.
前記装着工程の後に図１６および図１７に示す型締工程を実行する。型締工程においては、前記内足部３Ｍの周囲３２Ｍおよび前記外足部３Ｌの周囲３２Ｌにおいて前記積層体７のフォーム材６の厚さが薄くなるようにオス型１とメス型２とが型締めされる。
なお、内足部および外足部の周囲３２Ｍ，３２Ｌは、たとえば、図１０Ａおよび図１０Ｂに示すように、それぞれ、アッパー３の仮想の中心ラインに沿って延びている。 After the mounting process, a mold clamping process shown in FIGS. 16 and 17 is performed. In the mold clamping step, the male mold 1 and the female mold 2 are molded so that the thickness of the foam material 6 of the laminate 7 is reduced at the periphery 32M of the inner foot portion 3M and the periphery 32L of the outer foot portion 3L. It is tightened.
In addition, the circumferences 32M and 32L of the inner foot portion and the outer foot portion respectively extend along virtual center lines of the upper 3, as shown in FIGS. 10A and 10B, for example.
図１７において、前記型締工程の後に、前記内皮４０、外皮５０およびフォーム材６を所定の温度（例えば１６０°～１８０°程度）で所持時間（１５０ｓｅｃ～２５０ｓｅｃ）加熱し前記フォーム材６が前記部位に応じた厚さとなるように前記積層体７を成型して図１８の成形体８が得られる。前記メス型２には前記オス型ベース１１に向かって突出する図１５の切断部２２が設けられている。前記切断部２２がオス型ベース１１に当接ないし近接することで、前記内足部３Ｍの周囲３２Ｍおよび外足部３Ｌの周囲３２Ｌにおいて成形体８が薄く、かつ、脆くなる。
前記型締工程において、図１５～図１７に示すように、前記内皮材４、外皮材５およびフォーム材６は一対の金型１，２の歯合動作時に前記足型部１０および凹所２１の形状に沿って伸びるように変形される。また、前記型締工程の後に前記内皮材４、外皮材４およびフォーム材６は図７の一対の金型１，２からの伝熱により金型１，２の間のキャビティ内で昇温し軟化する。これにより、前記内外皮４，５およびフォーム材６は、元の形状に復元する応力を失いながら、同キャビティの形状に応じた形状や厚みとなる。前記内外皮４，５およびフォーム材６は、後に冷却されて、前記形状や厚みが維持される。なお、例えば前記フォーム材６の少なくとも一部が融解されてもよい。この場合、融解された前記フォーム材は元の形状に復元することなく所期の形状を得やすいだろう。また、同フォーム材は内外皮材に対しアンカー効果により固く付着されるだろう。 In FIG. 17, after the mold clamping step, the inner skin 40, the outer skin 50 and the foam material 6 are heated at a predetermined temperature (for example, about 160 ° to 180 °) for a holding time (150 sec to 250 sec), so that the foam material 6 The molded body 8 shown in FIG. 18 is obtained by molding the laminate 7 so as to have a thickness corresponding to the part. The female die 2 is provided with a cutting portion 22 of FIG. 15 protruding toward the male base 11. When the cutting part 22 is in contact with or close to the male base 11, the molded body 8 is thin and fragile in the periphery 32M of the inner foot part 3M and the periphery 32L of the outer foot part 3L.
In the mold clamping step, as shown in FIGS. 15 to 17, the inner skin material 4, the outer skin material 5, and the foam material 6 are used for the foot mold portion 10 and the recess 21 when the pair of molds 1 and 2 are engaged. It is deformed so as to extend along the shape. Further, after the mold clamping step, the inner skin material 4, the outer skin material 4 and the foam material 6 are heated in the cavity between the molds 1 and 2 by heat transfer from the pair of molds 1 and 2 in FIG. Soften. Thus, the inner and outer skins 4 and 5 and the foam material 6 have a shape and thickness corresponding to the shape of the cavity while losing the stress to restore the original shape. The inner and outer skins 4 and 5 and the foam material 6 are later cooled to maintain the shape and thickness. For example, at least a part of the foam material 6 may be melted. In this case, the melted foam material will easily obtain the desired shape without restoring the original shape. Also, the foam material will adhere firmly to the inner and outer skin materials due to the anchor effect.
その後、図１８の前記オス型１およびメス型２を型開きして前記成形体８が取り出される。その後、図１９の前記各周囲３２Ｍ，Ｌの薄くなった部位において前記積層体７が切断されて前記成形体８から不要部分８０が除去される。これにより、内足部３Ｍおよび外足部３Ｌが得られる。
前記内外足部３Ｍ，３Ｌについて、それぞれ、たとえば、前記不要部分８０の１つは、アッパーの履き口および開口（前記履き口に連なり舌片で覆われる）に相当する箇所の部分であり、残部は前記各周囲３２Ｍ，３２Ｌよりも外の部分である。 Thereafter, the male mold 1 and the female mold 2 in FIG. 18 are opened, and the molded body 8 is taken out. After that, the laminated body 7 is cut at the thinned portions of the surroundings 32M and L in FIG. 19 and the unnecessary portion 80 is removed from the molded body 8. Thereby, the inner foot part 3M and the outer foot part 3L are obtained.
For each of the inner and outer feet 3M and 3L, for example, one of the unnecessary portions 80 is a portion corresponding to an upper wear mouth and an opening (connected to the wear mouth and covered with a tongue piece), and the remaining portion. Is a portion outside the surroundings 32M and 32L.
その後、図２０に示すように前記内足部３Ｍと外足部３Ｌとは、内外の中央において互いに縫合される。本例では図１０Ａに示すように、爪先の上面、足裏および踵の後端にわたって内足部３Ｌと外足部３Ｌとが互いに縫合されている。 After that, as shown in FIG. 20, the inner foot portion 3M and the outer foot portion 3L are stitched together at the inner and outer centers. In this example, as shown in FIG. 10A, the inner foot portion 3L and the outer foot portion 3L are stitched together over the upper surface of the toe, the sole, and the rear end of the heel.
ところで、前記各実施例では、アッパーを全長にわたってプレス成型したが、アッパーの前足や後足などの一部を成型して得ることもできる。 By the way, in each said Example, although the upper was press-molded over the full length, it can also be obtained by shape | molding some front legs, back legs, etc. of an upper.
たとえば、以下のような方法でアッパーの後足のみをプレス成型してもよい。
すなわち、前足を有していない後足のアッパーは、積層工程、装着工程、型締工程、成型工程、型開工程、取り出し工程および不要部分の除去工程により得ることができる。 For example, only the upper rear leg may be press-molded by the following method.
That is, the upper part of the hind foot that does not have the front foot can be obtained by a lamination process, a mounting process, a mold clamping process, a molding process, a mold opening process, a removing process, and an unnecessary part removing process.
こうして得たアッパーの後足に常法により作成したアッパーの前足を接合し、アッパーが成形されてもよい。 The upper forefoot created by a conventional method may be joined to the rear leg of the upper thus obtained, and the upper may be molded.
以上のとおり、図面を参照しながら好適な実施例を説明したが、当業者であれば本明細書を見て、自明な範囲で種々の変更および修正を容易に想定するであろう。
たとえば、前記成形型又は成型前に、所定の部位に紐通し孔が機械加工等より形成されてもよい。更に、パーツがインサート成形されてもよい。
また、ピンがメス型に設けられ、ガイド孔がオス型に設けられてもよい。
また、金型の内足型および外足型は、１つのベースではなく、それぞれ別々のベースに設けられていてもよい。
