Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to shoes, and more particularly to an upper with a toe and a heel and a shoe made of the same.

[0002]

[Prior art]

 As is well known, shoe uppers are made of leather, plastics, fabrics or a combination thereof, but one of the essential requirements for these uppers is to be fairly flexible. . Usually, these materials are cut into respective members constituting each part of the upper, and then sewn to each other by a sewing machine to form the upper, and the upper thus formed already has an appropriate shape. However, since each cut member is originally flat, in order to make it into a curved three-dimensional shape that can be worn on the foot, the toe part, heel part, and waist leather part are formed by conventional laborious work. It is processed into a three-dimensional upper.

The upper is further formed into a relatively rigid structure by connecting an insole to the lower end by an adhesive bonding or stitching method. The upper is used to provide boots or a shaft portion and upper. When building boots, there is some inconvenience in finishing the shoe because the bottom end of the upper is already closed by the insole. That is, since the subcutaneous edge is closed and there is no passage to the inside of the shoe shell, operations such as connecting the boot shaft and the upper skin, stitching if brown, adhesive bonding, etc. It is necessary to insert the required tool through the opening of the plane, and since the operating space is narrow and it is far from the connecting part of the shaft part and the upper, it is inconvenient to finish the boot, especially the shaft part. It is quite difficult to insert the required tool into the upper through the top line opening of the to make a waterproof seal, and it can be seen that the conventional waterproof sealing process for the seam between the shaft of the boot and the upper is neglected. . On the other hand, even in the case of short shoes, the waterproof sealing when the insole is attached to the bottom line of the upper is performed from the top line opening of the upper, so it is also inconvenient and the upper is usually flexible. Does not maintain a three-dimensional shape, but presents a crushed state, and it requires time and effort to maintain a three-dimensional shape during the work. There are examples of attempts to solve.

In addition, in the conventional molding method of the upper shell, for example, the injection molding method and other molding methods, three-dimensional molding of each of the above-mentioned members, for example, the toe portion, the heel portion and the insole portion into a one-piece structure, and the above-mentioned stitching are performed. Although it solves the troublesome problem in the method, it is inevitable that the material for manufacturing the instep must be fairly flexible as described above, and therefore it is likely to be deformed when pressed. This one-piece molded shoe shell (instep) is used as the instep of the boot consisting of the shaft and the instep, or as the instep of boots.

FIG. 4 shows one of the boots, which is shown to use an appropriate insole 2 and an upper 1 molded integrally with the appropriate insole 2. Although the slit 3 is provided in the longitudinal direction from the toe portion to the heel portion, it is difficult to apply the waterproof sealing treatment to the seam between the shaft portion and the upper of the boot anyway. Then, the insoles 2 on both sides of the slit usually have a flat shape and are closely closed to each other, and they act as an obstruction during the work. Therefore, it is necessary to bend this portion to open the slit. . That is, the slit is not convenient as an entrance for processing operations such as sewing, adhesive bonding, waterproof sealing, etc., and even if an attempt is made to open the slit with a tool, the existence of the tool is rather reversed. It becomes a hindrance, and it is extremely difficult to carry out waterproof sealing with a tool through the slit. Therefore, the boot is not waterproofed and sealed at the joint between the shaft and the upper, and the closed bottom of the upper or the insole is to be processed internally. It is considered that there is no passage.

[0006]

[Problems to be solved by the device]

 As described above, the bottom line opening edge of a conventional shoe shell or upper does not have a flange or a curved portion for forming the flange, and it lacks rigidity, and the bottom line opening end of the shoe shell does not carry or carry a large amount. It is easily deformed or curved when stored. Even if the bottom line opening edge of the shoe shell is deformed, the adhesive joining or sewing work becomes inconvenient, which is inconvenient, so generally, after the shoe shell is molded, the bottom line opening edge is subsequently joined by adhesive joining or sewing. Although a shoe sole, such as an insole or an outsole, is connected to the shoe sole, because of the concern that the above problem will occur, the shoe sole is not attached to the shoe sole after the completion of molding the above-mentioned upper shoe. There is a hindrance to carrying out the division of labor by transferring to different work sites, factories or national characteristics.

In view of the above-mentioned problems in the conventional shoe shell structure or upper shell, the first object of the present invention is to provide a flange for strengthening rigidity at the opening edge of the bottom line to form a normally open passage. It is possible to avoid the deformation problem of the above, and to sew the seam between the upper and the shaft through the passage, perform the adhesive bonding or the waterproof sealing operation, and also have a rigid hollow shape that can be used as a shoe shell for boots or boots. It is to provide a one-piece upper.

A second object of the present invention is to manufacture the above-mentioned upper skin, and to apply a waterproof sealing treatment to the joint between the shaft portion and the upper skin or the joint between the upper skin and the sole of the shoe. It is to provide shoes such as boots or boots.

[0009]

[Means for Solving the Problems]

 In order to solve the above problems, the upper skin of the present invention has an integrated structure having a top line opening edge and a bottom line opening edge, and the toe part and the heel part are connected by both side surface parts thereof, A flange having an appropriate width is extended inward along the opening edge, and the annular edge of the flange surrounds and forms a longitudinally elongated opening whose width size is smaller than the lateral width of the bottom line opening edge. Both edges of the annular edge, which face each other in the width direction orthogonal to the longitudinal direction, are always kept at a constant interval. Further, shoes such as boots made by using the upper of the present invention are provided with a shaft portion and a sole in addition to the upper portion, and the shaft portion is connected to the top line opening edge of the upper portion, In addition, a shoe sole is connected to the bottom line opening edge of the upper, and the joint between the upper and the shaft is waterproofed.

It is more preferable to form a roundness between the flange and the bottom line opening edge of the upper.

In the present invention configured as described above, a flange having an appropriate width is extended inward along the bottom line opening edge of the upper to enhance rigidity, and thus the annular edge of the flange is used. There is no problem even if the shoe sole is joined and molded after the seam of the instep and the shaft portion is sewn through the opening formed in the enclosure, the adhesive joining or the waterproof sealing treatment is performed first, and the waterproof sealing treatment is performed. The manufactured shoes can be manufactured much more conveniently and separately compared to the prior art.

[0012]

[Embodiment of the invention]

 Hereinafter, the present invention will be specifically described based on an embodiment, but the present invention is not limited to this example.

As shown in FIG. 1, a relatively preferred embodiment of the upper of the present invention includes a unitary shoe shell 10 having a topline opening edge 11 and a bottomline opening edge 12, the shoe shell 10 comprising: It is composed of a toe portion 13, a heel portion 14, and both side surface portions 15 connecting the toe portion 13 and the heel portion 14, and the bottom line opening edge 12 has a flange 16 of an appropriate width extending inward along the peripheral edge. Is provided to enclose and form a longitudinally elongated opening 18 from the toe portion 13 to the heel portion 14 by the annular edge 17 of the flange 16 and the width size of the opening 18 crosses the bottom line opening edge 12. Make it smaller than the face length. The edge portion 17a of the annular edge 17 is the other edge portion of the annular edge 17 (17a indicated by the alternate long and short dash line in FIG. 1) facing each other in a direction orthogonal to the longitudinal direction extending from the toe portion 13 to the heel portion 14. Therefore, the opening 18 always has an open state. The shoe shell 10 can be molded by injection molding or other known molding methods, and the shoe shell 10 of the present invention may be molded using a conventional material for manufacturing the upper.

It should be noted that the flange 16 is molded to such a strength that the bottom line opening edge 12 of the shoe shell 10 can resist deformation, and the opening 18 is used for sewing, adhesive bonding and sealing operations. In this case, since a space that is easy to operate is provided inside the shoe shell 10 and the flange 16 is provided, a roundness 19 is formed at the bottom line opening edge 12 to make the wearer's foot feel comfortable. There is an advantage to give.

FIG. 2 shows a relatively preferred embodiment of a boot 20 made using the upper of the present invention, of which structural members are similar to those already shown in FIG. Other than the members, different numerical symbols are attached to the explanation. This embodiment includes a shaft portion 21, an upper 22, a midsole 23, and an outsole 24. The upper 22 is made of, for example, a waterproof material such as polyurethane, polyvinyl chloride or other elastic material. 21 is made of a relatively flexible material such as waterproof leather or imitation leather. Further, the midsole 23 is formed of ethylene vinyl acetate polymer, and the outsole 24 is formed of wear resistant rubber material.

The shaft portion 21 is assembled and manufactured by a conventional method, and includes an ankle joint area 21a and a cog 21b for passing a lace.

The upper 22 used in the present embodiment is the shoe shell 10 having the integral structure shown in FIG. 1, and the top line opening edge 11 of the upper 22 is used as the bottom line opening edge of the shaft portion 21. The bottom line opening edge 12 of the upper 22 is connected to the midsole 23, and the joint 25 between the bottom line opening edge of the shaft 21 and the top line opening 11 of the upper 22 is sewn. The joints are joined together, and a waterproof layer 26 as shown in FIG. 3 is further provided on the joint 25.

When the boot 20 is assembled and formed, first, the upper 22 and the shaft portion 21 are joined by the stitching method to form the joint 25, and then the conventional method is used to form the joint 25, for example. A waterproof agent is rubbed into the joint 25 or a waterproof tape is attached to the joint 25 to seal the joint 25 with a waterproof layer 26. That is, since the bottom 18 of the upper 21 has the opening 18, the seam 25 can be conveniently sealed by inserting a tool through the opening 18. Subsequently, the midsole 23 and the outsole 24 are connected to the bottom line opening edge 12 of the upper 22 by a conventional method. What we would like to mention here is that the opening 18 is not only large and the shaft 18 is not large. Since it is closer to the joint 25 than the top line opening edge of the portion 21 and forms an insertion port of the tool into the upper 22 and facilitates the work operation in the joint 25. It is convenient for watertightly treating the joint 25 of the boot 20 using the upper of the present invention.

Next, as shown in FIG. 3, an insole 28 is connected to the bottom line opening edge 12 of the upper 22 by a sewing method, and an outsole 24 is joined by a conventional method, and the conventional method is used. Thereby, the waterproof layer is rubbed or the waterproof tape is attached to the bottom surface of the insole 23 and the adjacent surface of the upper 22 and the midsole 23 to form the waterproof layer 27. What is clarified here is that the bottom line opening edge 22 of the upper 22 is provided with the flange 16, so that the rigidity is improved as compared with the conventional shoe shell having the bottom line opening edge. It is possible to easily carry out various manipulations inside the joint 25, and these manipulations cannot be achieved by the conventional shoe shell having no bottom closure or bottom opening. The flange 16 is joined to the midsole 23 with a larger connecting area.

[0020]

[Effect of the invention]

 According to the present invention constructed as described above, since the flange having an appropriate width is extended and strengthened inward along the bottom line opening edge of the upper skin, it is surrounded by the annular edge of the flange. Even if the insole and the outsole are joined and formed after the seam of the upper shell and the shaft portion is sewn through the opening, the adhesive joining is performed, or the waterproof sealing treatment is performed, the problems of the prior art are not caused. In addition, the shoe manufacturing process can be performed easily and conveniently, and it is naturally allowed to transport the upper to a different work place, factory or national pattern for division of labor. Further, it is possible to easily build up a shoe that is waterproof and sealed at the joint between the shaft portion and the upper or the joint between the upper and the sole using the above upper.
