Description

  The present invention relates to a shoe that is easily adapted to a user's foot and is also suitable for custom-made.

  For example, ready-made shoes are manufactured by inflating an instep cover that covers the instep of the foot and integrating it with the insole, and attaching the bottom to the bottom surface of the insole. The upper is covered with a foot shape with an insole attached to the bottom surface, and after undergoing fishing to adjust the outer shape to the shape following the foot shape, the lower edge is in contact with the upper surface of the outer peripheral portion of the inner bottom or the lower surface of the outer peripheral portion. And sewn. The lower edge of the upper and the outer periphery of the insole are bent outward (Patent Document 1, [0002] to [0005], [FIG. 4] to [FIG. 6], so-called stitch-down structure) Or bent inside the insole and concealed by the main bottom (Patent Document 2, [Claim 1] [0005] [Fig. 1] and [Fig. 2], for example, cement structure).

Japanese Patent Laid-Open No. 10-137004 Japanese Patent Laid-Open No. 2001-095605

  Shoes that attach the sole to the insole to which the upper is sewn are attached to the bottom of the foot when the upper is inflated, so the surface of the insole often follows the bottom of the foot. Shape. Here, in order for the shoe to fit the user's foot, it is desirable that the upper is shaped like the back of the foot and the surface of the insole is shaped like the sole of the foot. However, with conventional shoes, it is difficult to individually manufacture the foot mold that determines the surface of the insole according to the sole of the user's foot, and the surface of the insole is molded according to the bottom surface of a general-purpose foot mold. I must. For this reason, when the shoe is adapted to the user's foot, an insole formed in a shape following the sole of the user's foot has been inserted separately.

  In addition, shoes that attach the bottom to the insole to which the upper is sewn are sewn on the lower edge of the upper and the outer periphery of the insole, and then the upper is folded with the sewn part facing outward. There is a problem that it is difficult to mold the upper in accordance with the legs of the user because the condition is adjusted and the above-mentioned sewing portion is directed inward and hidden from the bottom. This means that shoes that attach the bottom to the insole to which the upper is sewn are not suitable for custom-made. Therefore, we studied to provide shoes that are easy to adapt to the user's feet and are suitable for custom-made.

As a result of examination, the upper and the sole are joined to each other, and the shoe is configured by placing the insole on the sole, and the upper is previously molded into an outer shape that follows the foot shape. The front and rear sides corresponding to the toes and heels of the upper are relatively thick and the left and right sides sandwiched between the front and rear sides are relatively thin from the outer periphery of the upper surface to the inside of the upper thickness . An annular joining wall is provided, and the lower edge of the upper is joined to the joining wall in a state where the lower edge of the upper covering the bottom of the bottom is in contact with the outer surface of the joining wall. A shoe was developed that was placed on the bottom and concealed the inner part of the upper and the joint wall. The shoes of the present invention can be applied regardless of whether they are men's shoes (for example, men's shoes) or women's shoes (for example, pumps).

  In the shoe of the present invention, the upper and the bottom are joined, and the insole is placed on the upper surface of the bottom or a separately formed fitting plane (see later). The upper is molded in advance following the foot shape, and after joining to the joint wall of the bottom, the joined portion is not bent. Accordingly, the upper can be easily adapted to the user's foot if the outer shape is formed following the foot shape imitating the user's foot. Further, since the insole is only placed on the upper surface of the bottom sole joined to the upper, it can be formed into a shape that follows the sole of the user's foot regardless of the bottom surface of the foot mold. Moreover, since the insole has a thickness that hides the inside of the joint portion of the upper and the joint wall, the insole has a high degree of molding freedom and can be easily shaped to follow the sole of the foot. The structure in which the lower edge of the upper is joined to the outside of the joining wall opens the joining portion of the upper and the joining wall downward. Further, the structure in which the inside of the joint portion of the upper and the joint wall is hidden by the insole does not hit the joint portion on the user's foot.

  The upper is joined to the joint wall with the lower edge part cut off from the outer edge of the upper surface of the outsole as a surplus, and the part protruding from the outer edge of the upper surface of the outsole is cut out as a surplus to the user's foot. Adjust to the appropriate outer shape. The bottom is provided with guide strips extending in parallel with the outer peripheral edge of the upper surface on the outer peripheral surface, and the lower edge portion of the upper and the joint wall are joined together by sewing along the guide strips. In addition, the bottom is relatively thick on the front and rear sides of the joint wall corresponding to the toes and heels of the upper, and the left side of the joint wall sandwiched between the front and rear sides (for example, if the shoe is for the right foot, The inner side) and the right side (for example, the outer side of the foot if the shoe is for the right foot). The main bottom is provided with a reference mark between the outer surface of the joining wall and the outer peripheral edge of the upper surface or on the outer surface of the joining wall. The reference mark may be anything as long as it can specify the circumferential position of the joining wall. Further, a pair of reference marks may be provided on the outer surface of the joining wall in the front-rear direction, and the direction connecting the two may be defined as the front-rear direction.

  If the inner surface of the joint wall has a taper surface with a downward slope from the outside to the inside, even if it is a flat insole that is equal to the planar shape surrounded by the inner surface of the joint wall, it can be easily fitted inside the joint wall. Become. In this case, the insole forms a reverse taper surface that is a transfer shape of the taper surface of the joining wall, and the taper surface and the reverse taper surface are brought into close contact with each other or elastically deformed or plastically deformed itself. It is advisable to prevent gaps from occurring. When the lower edge portion of the upper and the joining wall are sewn, the strength of the joining wall can be ensured by sewing below the tapered surface. Further, the bottom has a fitting plane that is lower than the upper surface on the inner side of the joining wall, and an insole that satisfies a range surrounded by the joining wall and the fitting plane is placed on the fitting plane, and the insole is covered with the insole. And if it is the structure which hides the junction part inside of a joining wall, it comes to be able to fit an insole into a sole, and can prevent lateral displacement of an insole better. In addition, since an insole thicker than the height of the joining wall can be used, the degree of freedom in forming the insole is increased.

  The present invention provides a shoe that fits a user's foot and is suitable for custom-made. In addition to being able to be used without deforming the upper that has been molded to the outer shape in advance to follow the foot shape, the insole that does not need to be joined to the upper is thickened to follow the sole of the user's foot This is an effect of being able to be formed into a shape. The structure in which the lower edge of the upper is joined to the outer surface of the joint wall opens the joint portion of the upper and the joint wall downward, and thus has an effect of preventing dust and water from entering. Further, the structure in which the inside of the joint portion of the upper shell and the joint wall is hidden by the insole has an effect of not causing discomfort because the joint portion is not applied to the user's foot.

  The structure that joins the lower edge of the upper shell with the excess cut off to the joint wall adjusts the length of the lower edge of the upper shell with respect to the joint wall and forms the outer shape to fit the user's foot The effect that can be done. The guide strip provides a sewing machine track when sewing the lower edge of the upper and the joint wall to join, and has the effect of neatly finishing the sewing line and improving the aesthetics of the bottom. . The joint walls with the front and rear sides relatively thicker than the left and right sides make it easier to deform the left and right of the upper according to the movement of the foot while suppressing the deformation of the toes and heels of the upper. The combination of shape retention and partial shoe flexibility makes it possible to provide shoes with excellent comfort. The reference mark has an effect of grasping the direction of the upper with respect to the bottom (for example, grasping the center deviation of the upper with respect to the bottom) and accurately cutting off the excess protruding from the outer peripheral edge of the upper surface of the bottom.

  The joint wall has a tapered surface with a downward slope from the outside to the inside so that no step is formed at the boundary between the joint wall and the upper so that the comfort is not impaired and the insole is easy to fit. Thus, for example, it is possible to easily fit an insole formed in accordance with the sole of the user's foot into the inside of the joint wall. Further, the structure in which the insole is placed on the fitting plane lower than the upper surface and fitted inside the joining wall has an effect of preventing the lateral displacement of the insole thicker than the height of the joining wall. Thus, the shoe of the present invention can adjust the outer shape of the upper, and the insole can be formed in accordance with the sole of the user's foot, but it can be moved to the inside of the joining wall without being displaced. A shoe suitable for custom-made, such as being easily fitted, can be obtained.

It is an exploded perspective view showing an example of shoes to which the present invention is applied. It is a top view showing the bottom of this example. It is a side view showing the bottom of this example. It is AA sectional drawing in FIG. It is BB sectional drawing in FIG. It is a side view showing the state which covers the upper shell with a surplus on the bottom. It is a side view showing the state which sewn the lower edge part of the upper and the joining wall. FIG. 5 is a cross-sectional view corresponding to FIG.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. As shown in FIG. 1, the shoe 1 of the present invention has a semi-order specification and is mainly composed of an upper 2, a bottom 3 and an insole 4. The shoe 1 of this example illustrates only for the right foot for explanation. The left foot is manufactured symmetrically with the shoe 1 of this example. However, as will be described later, an appropriate amount of the lower edge 21 of the upper 2 can be excised and the cross-sectional shape can be shaped according to the user's foot. It may be different.

  The upper 2 is formed in advance in an outer shape following a foot shape (not shown). However, the upper 2 of this example forms surplus 211 (see FIG. 6 described later) on the left and right sides of the lower edge portion 21 so that the cross-sectional shape can be shaped following the user's foot. After the appropriate amount of the surplus 211 is excised, the upper 2 is in contact with the lower edge 21 against the upper surface of the bottom 3 and with the inner surface of the lower edge 21 facing the outer surface 321 of the joining wall 32. The joint wall 32 is sewn. A sewing line 22 between the upper 2 and the joining wall 32 appears parallel to the upper surface 31 of the bottom 3.

  The material of the upper 2 is not limited. The material of the upper 2 may be any material as long as it retains the outer shape that has been formed in advance by following the foot shape and can relatively easily cut off the surplus 211 that is provided for forming the cross-sectional shape. Further, the shoe 1 of this example is an example in which the lower edge portion 21 of the upper 2 is sewn to the joining wall 32 of the outsole 3. However, if the joining means has sufficient joining strength and is difficult to separate, it can be bonded. I do not care. When using adhesion as a joining means, in addition to using an adhesive, it is also conceivable to thermally or ultrasonically weld the resin upper 2 and the joining wall 32.

  The upper 2 is formed with surplus 211 over the entire circumference of the lower edge portion 21, and may be shaped in all of the front, rear, left and right of the upper 2. However, the part that requires adjustment of the upper 2 is mainly the upper part of the foot 5 (see FIG. 6 described later, the same applies hereinafter), and there is little need to adjust the front and rear toes and heels. Rather, it is preferable to form a cross-sectional shape corresponding to the back of the user's foot 5 so that the left and right lower edge portions 21 can be adjusted with the front and back of the upper 2 as they are, and the front and rear as a reference. The surplus 211 in this example has a substantially crescent shape with a continuous contour on the lower edge 21 in the front and rear, but if the surplus 211 can be excised so that the continuity of the lower edge 21 is maintained in appearance, for example, the front and back A substantially rectangular protrusion having a step with respect to the lower edge portion 21 may be used.

  As shown in FIGS. 1 to 5, the bottom 3 is an integrally molded product made of rubber in which an annular joining wall 32 is provided from the outer peripheral edge of the upper surface 31 to the inside of the upper shell. A guide strip 331 is formed on the outer peripheral surface 33 of the main bottom 3 of this example along the outer peripheral edge of the upper surface 31. Further, the main bottom 3 of the present example has an inner side surrounded by the joining wall 32 as a fitting plane 34 deeper than the upper surface 31. In the fitting plane 341 of this example, three concave grooves 341 extending left and right are provided at equal intervals in the front-rear direction from the front-rear middle to the front side so that the bottom 3 can be easily bent forward and backward. The bottom 3 is provided with the concave groove 341 so that the vicinity thereof is relatively easily bent forward and backward as compared to the front and rear.

  Since the joining wall 32 of this example is provided with a fitting plane 341 lower than the upper surface 31 on the inner side, the inner surface 322 standing from the fitting plane 34 is longer than the outer surface 321 standing from the upper surface 31. The insole 4 has a thickness that follows the upper edge of the joining wall 32 and has an inversely tapered surface 41 that serves as a transfer structure for the tapered surface 323 of the joining wall 32, thereby closely contacting the tapered surface 323 and the inner surface 322. Conceal both. If the insole 4 is deformed by the weight of the user's foot 5, the upper edge of the joint wall 32 may touch the user's foot 5. The tapered surface 323 reduces the level difference of the upper edge of the annular wall 32 with respect to the inside of the upper 2 so as to reduce the uncomfortable feeling caused by the contact of the upper edge.

  The joining wall 32 is an annular wall similar to the contour shape in plan view of the outsole 3 (see FIG. 2). The joining wall 32 in this example has a thickness (interval between the outer surface 321 and the inner surface 322) that is not uniform in the circumferential direction, and the front and rear thicknesses Fth and Bth are relatively thick, and the inner side (left side) and the outer side. The thicknesses Ith and Oth of the (right side) are relatively thin (comparison of FIGS. 4 and 5). The change in thickness is continuous in the circumferential direction, and there is no step in the circumferential direction. The joining wall 32 of this example is not easily deformed on the thick front side and the rear side, the joining with the upper 2 is stable, the thin inner side and the outer side are easily deformed, and the deformation of the upper 2 is not hindered.

  In addition, the joining wall 32 of this example is provided with a front reference mark 324 and a rear reference mark 325 on the front and rear outer surfaces 321 respectively. The front-side reference mark 324 and the rear-side reference mark 325 in this example are vertical stripes extending from the upper edge of the joining wall 32 to the upper surface 31 of the bottom 3 and are recognized as appearance lines with almost no thickness. The front reference mark 324 and the rear reference mark 325 serve as a reference for the front side and the rear side of the upper 2 respectively. In addition, a lateral shift of the upper 2 with respect to the bottom 3 is confirmed from a straight line connecting both.

  The manufacturing procedure of the shoe 1 based on this invention is demonstrated. The upper 2 and the outsole 3 are selected from semi-finished products having different sizes manufactured in advance according to the size of the user's foot 5. The upper 2 has surplus 211 on the inside and outside of the lower edge portion 21 and cuts off the surplus 211 in accordance with the user's foot 5. The position and size of the surplus 211 removed from the upper 2 are determined by adjusting the direction of the upper 2 in accordance with the front reference mark 324 and the rear reference mark 325 provided on the joining wall 32 of the outsole 3. .

  Specifically, the insole 4 formed in a shape that follows the back of the user's foot 5 is temporarily placed on the fitting plane 34 of the outsole 3, and the user's foot 5 is placed on the insole 4 Then, as shown in FIG. 6, the selected upper 2 is placed on the outer side of the joining wall 32 of the outsole 3, and the upper reference mark 324 and the rear reference mark 325 provided on the joining wall 32 are covered. After the orientation of 2 is adjusted, the surplus 211 that the lower edge portion 21 of the upper 2 shaped according to the user's foot 5 protrudes from the upper surface 31 of the bottom 3 is specified. The insole 4 may be temporarily fixed with an adhesive or the like so that it does not slip when the surplus 211 is specified, but is temporarily removed when the upper 2 is sewn to the bottom 3 after the surplus 211 is specified. . The surplus 211 is excised as it is after specification, or is excised from the upper 2 removed from the bottom 3.

  As shown in FIG. 7, the upper 2 from which the surplus 211 has been removed has the lower edge portion 21 abutting against the upper surface 31 of the bottom base 3 and contacting the outer surface 321 of the joining wall 32 over the entire circumference. Sews to the wall 32. Since the insole 4 is an obstacle to the sewing work, it is temporarily removed. The lower edge 21 of the upper 2 and the joint wall 32 of the bottom 3 are sewn using a dedicated sewing machine (for example, BC20 / 9 manufactured by CMCI, Italy). The dedicated sewing machine has the same height over the entire circumference by moving the needle along the guide strip 331 provided on the outer peripheral surface 33 of the outsole 3. The lower edge 21 of the upper 2 and the joint wall 32 of the bottom 3 can be sewn, and the sewn line 22 can be finished beautifully. The sewing line 22 is formed between the lower edge of the tapered surface 323 of the joining wall 32 and the upper surface 31 of the bottom base 3 (a portion thicker than the tapered surface 323), and the joining strength by sewing is ensured.

  After joining the upper 2 and the outsole 3 by sewing, as shown in FIG. 8, a separately formed insole 4 is inserted into the upper 2 and the mating plane 34 of the outsole 3 is inserted. The shoe 1 is completed. The insole 4 is a custom-made type in which irregularities are formed in advance on the back of the user's foot 5 and is not bonded to the bottom 3 in order to be exchangeable. The custom-made insole 4 can be manufactured by using various conventionally known devices (for example, HDVAC2 manufactured by Sidus). Since the insole 4 in this example is placed on the fitting plane 34 formed inside the joining wall 32 of the bottom 3, the thickness is equal to the total height of the inner surface 322 and the tapered surface 323 of the joining wall 32. Yes. For this reason, the insole 4 has a degree of freedom in forming the surface, and can easily form an uneven surface matched to the back of the user's foot 5.

  In this way, the thick insole 4 hides the inside (joint portion inside) of the sewing line 22 between the lower edge portion 21 of the upper 2 and the joining wall 32 of the outsole 3. The insole 4 in this example has a reverse taper surface 41 that is a transfer shape of the taper surface 323 of the joining wall 32, and the reverse taper surface 41 is in close contact with the taper surface 323 so as to hide it. The entire joining wall 32 can be hidden (see the enlarged portion in FIG. 8). This eliminates the possibility that the inner side of the sewing line 22 contacts the user's foot 5 to give a sense of incongruity. As described above, even if the insole 4 is elastically deformed and the upper edge of the joining wall 32 is exposed from the surface of the insole 4, the inner surface of the upper 2 is joined by the tapered surface 323 provided on the joining wall 32. There is no possibility that a step is felt inside the wall 32 and the user's foot 5 is uncomfortable. Rather, the shoe 1 of the present invention can provide good comfort because the cross-sectional shape of the upper 2 and the surface of the insole 4 match the foot 5 of the user.

  Thus, the shoe 1 of the present invention is completed by the procedure of joining the upper 2 to the bottom 3 and inserting the insole 4. As described above, the insole 4 is not bonded to the bottom 3 in order to be exchangeable. The upper 2 is shaped in advance so as to follow the foot shape, and can be joined to the bottom 3 only by excising the surplus 211 of the lower edge 21. The insole 4 can be formed as a made-to-order product. Both of these operations are possible at a sales store, and do not take much time. From now on, by utilizing the present invention, a custom-made shoe 1 matched to the user's foot 5 can be provided.
