Description

  The present invention relates to a shoe having leather or artificial synthetic leather as a sole, and in particular, by fitting a cushioned thick medium article to the sole, while maintaining the flexibility and flexibility of the shoe and The present invention relates to a shoe that has a certain thickness and can improve comfort.

  Conventionally, various shoe manufacturing methods have been devised and widely used. In particular, there are manufacturing methods such as the Goodyear Welt manufacturing method, the McKay manufacturing method, and the rubber manufacturing method (cement type) as traditional manufacturing methods. Various manufacturing methods are selected and used according to the shape and application of the shoe Has been.

  The Goodyear welt manufacturing method is a manufacturing method in which an upper, a lining, and a welt (thin leather) are sewn to a rib attached to an insole, and then the welt and a sole (sole) are sewn together. The McKay manufacturing method is a manufacturing method in which the upper and the bottom are directly sewn with a dedicated sewing machine (McKay sewing machine). The rubber manufacturing method (cement type) is a manufacturing method in which the upper and the bottom are not sewn as in the Goodyear Welt manufacturing method, but are bonded with an adhesive. Each of these is a manufacturing method that has been widely used for a long time, and each has advantages and disadvantages. Therefore, methods and techniques for manufacturing various shoes with improved shortcomings have been developed.

  For example, in Japanese Patent Application Laid-Open No. 2011-235066, as a technique related to the structure of a shoe, an upper (upper) is placed along the outer periphery of the insole into which a sufficient space for filling a cushion material is removed. After the direct sewing, the bottom of the sole is filled by filling the bottom of the bottom with cushion material, and then sewing the bottom and the other bottom along the common outer circumference. It is disclosed. It is suggested that this technology makes it possible to produce shoes that combine the flexibility and design of the Mackay manufacturing method with the durability and cushioning of the Goodyear welt manufacturing method.

  According to this manufacturing method, it is said that it is possible to produce shoes having both flexibility and cushioning properties. However, according to this technique, the layer filled with the cushioning material and the layer to be grounded are made of different leathers, and there is a possibility that water will be immersed in the shoe from the gap unless the two are securely joined. Further, since the number of types of members constituting the shoe increases, it cannot be said that the cost required for manufacturing can be reduced.

  Also, in Japanese Patent Application Laid-Open No. 2014-167331, as a technique related to comfortable shoes in accordance with differences in the shapes of the soles of various people, the shoe sole and the shoe sole side end are partially folded inward. Further, there is disclosed a technique having a platform structure including an upper and a cushion disposed in the shoe, wherein the cushion is detachably disposed on the shoe bottom. According to this technology, it is possible to attach and remove cushion materials without disassembling the platform structure while having the features of platform structure shoes, and comfortable shoes that match the uneven shape of various people's soles. It is suggested that it will be possible to provide.

  However, according to this technique, there are problems that the types of members constituting the shoe increase and the structure becomes complicated, and further, it is difficult to ensure sufficient flexibility from the viewpoint of flexibility. It was.

Shoes with leather or artificial synthetic leather as the sole have a problem that they are hard to walk and easily rub the shoes immediately after production because the leather is hard. Therefore, it has been desired to develop a shoe that is flexible even before the leather gets used, and that is comfortable while keeping the flexibility of the shoe.

  In order to solve the above-mentioned problem, the present invention is a shoe having leather or artificial synthetic leather as a sole, and in particular, a medium consisting of a cushioned thick layer is fitted to the sole to be flexible. Providing shoes with good comfort while maintaining the flexibility and flexibility of shoes.

  In order to achieve the above object, a shoe according to the present invention is a shoe comprising a bottom made of leather or an artificial synthetic leather material, a cushioning medium placed on the bottom, and an upper. In order to improve the comfort of the shoe while maintaining the flexibility of the shoe, the outsole is provided with a fitting recess in the center so that a rib is erected at a fixed position along the outer periphery of the shoe sole, The inside is formed in the same shape as the fitting recess, the inside is fitted in the fitting recess, and the upper is fixed to the bottom by sewing the periphery of the upper to the rib with a sewing thread. It is.

Moreover, the said shoes are the structures which installed the insole on the inside item of shoes.
In addition, the upper has a folding part in which the bottom end of the bottom is folded inward, and the upper is fixed to the bottom by sewing the folding part and the rib to be erected. is there.

In addition, the fitting recess is configured to be cut so as to be the same height as the inside object.
Further, the shoe has a configuration in which an insole having a length approximately half of the bottom is fitted to the heel portion of the bottom.
Furthermore, the said insole is also the structure which installed the plate-shaped core along the longitudinal direction of shoes.

Since the present invention is configured as described in detail above, the following effects are obtained.
1. Since the fitting recess is cut out in the center of the bottom, the flexibility of the bottom is ensured, and a shoe that maintains the overall flexibility can be configured. In addition, since the rib is erected along the outer periphery of the bottom bottom in accordance with the cutting of the fitting recess, it is possible to easily form a portion where the upper and the bottom bottom are stitched. Moreover, since it is set as the structure which inserts the inside thing with cushioning properties in a fitting recessed part, it becomes possible to provide a comfortable shoe with a certain thickness.
2. Since the insole is installed on the midsole, it is possible to suppress the displacement and deformation of the midsole and improve the comfort.

3. Since the folding portion is provided at the upper bottom end portion of the upper, it becomes possible to finish the junction between the main bottom and the upper neatly.
4). Since the fitting recess has been cut so as to be the same height as the height of the midsole, the midsole and the bottom are integrated.

5). Since the insole of approximately half the length of the bottom is fitted to the heel of the bottom, it is possible to ensure comfort even with high heels with high heels.
6). Since the plate-shaped core is provided on the insole, it is possible to prevent deformation of the insole.

Hereinafter, the shoes according to the present invention will be described in detail based on the embodiments shown in the drawings. FIG. 1 is a sectional view of a shoe according to the present invention, and FIG. 2 is a sectional view of a shoe produced by the Goodyear Welt manufacturing method. FIG. 3 is a cross-sectional view of the valley shoe, and FIG. 4 is a perspective view of the bottom with the insole inserted.
The shoe 1 of the present invention is a shoe that includes a bottom 10, a midsole 20, an upper 30, and a sewing thread 60, and has both flexibility and comfort.

  The outsole 10 is a member of the bottom portion of the shoe. Since the member is in direct contact with the ground or the like, sufficient rigidity is required, and in this embodiment, leather or artificial synthetic leather is used as the material in order to reduce the load during walking. The bottom 10 is not limited to leather and artificial synthetic leather as in the present embodiment, and other materials such as reinforced rubber having rigidity and flexibility can be used.

  The midsole 20 is a cushioning member installed in the bottom 10. In this embodiment, rubber, flexible urethane foam, felt, or the like is used as the material of the midsole 20, but is not limited thereto, and may be appropriately selected and used depending on the use of the shoe. Is possible. Further, the upper 30 is a part of the instep of the shoe 1, and in this embodiment, as shown in FIG. 1, the upper 30 is constituted by a front leather 32 that becomes the surface of the shoe 1 and a back leather 34 that becomes the inner wall of the shoe 1. Has been. The shoe 30 is formed by sewing the upper 30 to the bottom 10 on which the midsole 20 is installed.

  As shown in FIG. 4, a fitting recess 50 is provided at the center of the bottom 10. The fitting recess 50 is a concave recess cut in the outsole 10, and in this embodiment, as shown in FIG. 1, a constant width is left along the outer periphery of the shoe sole, and the center portion is shaved. The fitting recess 50 is formed. Further, in this embodiment, by further cutting with a constant width from the outer peripheral edge of the shoe sole, the rib 40 is left standing in a fixed position on the inner side along the outer periphery of the shoe sole. ing.

  The intermediate product 20 is formed to have the same shape as the cut-out fitting recess 50. Thereby, it becomes possible to fit the inside 20 into the fitting recess 50. In this embodiment, the fitting recess 50 is formed by scraping the inside of the outsole 10 along the outer periphery of the shoe sole while leaving a certain width, so that a recess into which the inside 20 is fitted can be easily formed. Further, since the dent is cut out on the thick outsole 10, the shoe sole becomes soft and the flexibility of the shoe can be secured.

  Since the midsole 20 is stabilized in the shoe by being fitted into the fitting recess 50, there is no fear of shifting during walking. Moreover, since it is a member with a cushioning property, the comfort of shoes is improved.

  The upper 30 is configured to be firmly fixed to the bottom 10 by sewing the periphery of the rib 40 formed by shaving the bottom 10 with a sewing thread 60. As shown in FIG. 1, the rib 40 is erected vertically. The bottom 10 and the upper 30 are sewn and fixed by sewing the end portion of the upper 30 with the sewing thread 60 from the outside of the vertically erected rib 40. With this structure, the bottom 10 and the upper 30 can be easily stitched together.

  For example, according to the conventional Goodyear welt manufacturing method, as shown in FIG. 2, after inserting the midsole 120 between the bottom 110 and the insole 170, the welt 140, the upper 130 and the insole 170 are raked. The shoe 100 is manufactured by stitching at 160, further pulling out the welt 140 and the outsole 110 and stitching with the sewing thread 162. This manufacturing method has a problem in that it is difficult to ensure the flexibility of the shoe because the sole remains thick. Further, when the midsole 120 has a high cushioning property, the thickness of the shoe sole increases, so it is difficult to ensure the flexibility of the shoe and improve the comfort. This was the same in the cement type manufacturing method and the McKay manufacturing method.

  Further, according to the production method of the valley shoes, as shown in FIG. 3, the shoe 200 directly stitches the bottom sole 210 and the upper 230 with the sewing thread 260, so that it is difficult to make the bottom sole thick, Although it is possible to insert the insole 270, since it is difficult to insert the insole, there is a problem that it is difficult to improve the comfort even if the flexibility of the shoe can be secured. Moreover, since it is a unique structure as a valley shoe, there was a lack of versatility.

  Since the shoe 1 according to the present invention has a configuration in which the midsole 20 is fitted in the fitting recess 50 cut out on the outsole 10, the above-mentioned problems are solved, and the flexibility of the shoe is secured and the comfort is improved. Furthermore, it has become possible to ensure versatility at the same time.

  As shown in FIG. 1, the shoe 1 may have a configuration in which an insole 70 is installed on the midsole 20 inside the shoe 1. By adopting this configuration, it is possible to prevent displacement, peeling, and dropping of the midsole 20, improve ease of wearing, and achieve a cleaner inner design.

  As shown in FIG. 1, the upper 30 can be configured to have a folded portion 36 in which an end portion on the bottom 10 side is folded inward. In the present embodiment, the bottom 10 and the upper 30 are stitched together via the ribs 40, and the bottom 10 and the upper 30 are fixed by sewing the folding portion 36 and the standing rib 40. Thus, it is possible to finish the joining portion between the outsole 10 and the upper 30 neatly and increase the strength of the joining portion, so that the sturdy shoe 1 can be configured.

  In the present embodiment, the fitting recess 50 is configured to be cut so as to be the same height as the height of the intermediate 20 as shown in FIG. With this configuration, the upper surface of the midsole 20 and the tip of the rib 40 are flush with each other, so that the outsole 10 and the midsole 20 are integrated with each other, and when the shoe 1 is worn, It is possible to provide a comfortable shoe 1 without feeling uncomfortable feeling such as unevenness.

  As another embodiment of the shoe 1 according to the present invention, as shown in FIG. 4, a configuration is adopted in which an insole 80 having a length approximately half of the bottom 10 is fitted to the heel portion 11 of the bottom 10. It is possible. In this embodiment, the insole 80 is fixed by McKay stitches after being bonded to the main bottom 10. With this configuration, when a heel is attached to the shoe heel, it is possible to prevent the bottom 10 from hanging down due to a step, and the shoe 1 according to the present invention is applied to a high heel with a heel. Even if it exists, it becomes possible to ensure comfort.

  As shown in FIG. 4, the insole 80 has a configuration in which a plate-shaped core 82 is installed along the longitudinal direction of the shoe 1. With this configuration, it is possible to prevent the deformation of the insole 80, and it is possible to configure a shoe 1 that is sturdy and difficult to deform and that lasts long. In the present embodiment, the insole 80 uses the same leather or artificial synthetic leather material as the outsole 10, but is not limited to this, and any material having an appropriate strength can be selected as appropriate. is there. Further, the core 82 can be appropriately selected and used as long as it is a rigid material having an appropriate strength strong against twisting.
