Description

[Detailed Description of the Invention] [Industrial field of application] According to the present invention, a ridge is provided around a ridge surrounding a ridge extending from a connecting portion between a skin body constituting a skin and a shoe sole to an upper edge of the shoe sole. And a slash shoe in which these skins and ridges are individually formed.

[Prior Art] Conventionally, in a slash shoe including a skin in which a shoe sole is integrally formed on a lower peripheral edge of a skin main body, from a connecting portion between the skin main body and the shoe sole to an upper edge portion of the shoe sole. The ridge is provided around the ridge surrounding portion.

Incidentally, the conventional ridge is integrally formed by the slush method with the same material having the same hue as this skin.

[Problems to be solved by the device]

By the way, in the conventional slash shoes, the ridge is integrally formed with the material having the same hue as that of the skin, so in order to make the hue of the ridge different from the skin and improve the design of the shoe, Since the paint had to be applied to the surface of, the workability was poor and the incidence of defective products was relatively high.

Similarly, since the ridge and the skin are integrally formed of the same material, it is difficult to make the skin and the ridge different from each other to further improve the functionality and design of the shoe.

In addition, because it is difficult to perform sewing on only this ridge due to its structure, it is not possible to further improve the design of the shoe by sewing the stitch sew on the ridge with stitch threads to create the texture of leather shoes. It was

Temporarily, the slash shoe is provided with a skirt with a flat shape on the side of the skin around the skin where the shape of the connecting portion between the body of the same shape and the sole of the shoe has a substantially right-angled shape in cross section. In such a case, pinholes may be generated at the connecting portion between the skin body and the shoe sole during the molding of the skin due to the fact that air bubbles do not escape during the slush manufacturing method. Further, when the skin is released from the mold, it is difficult for the skin to be released from the skin because it is caught in the corner of the connecting portion having a substantially right angle.

Moreover, since this skin is manufactured by the slush molding method, the inner surface of the skin has irregularities, so it is difficult to insert the last that fits properly at this connecting part into the skin, which results in the lower peripheral edge of the skin body. The connection between the edge and the ridge tends to be insufficient.

Further, even when using this slash shoe, the connecting portion between the skin body and the shoe sole has a substantially right-angled shape in cross section as described above, so that the load due to the bending of the shoe during walking is There is also a risk that the shoes may be damaged by concentrating on the corners of this connecting portion.

The present invention has been made on the background of such a conventional technique, and it is possible to easily make the skin and the rim different in color and different from each other, and it is also possible to use the rim sewn by the sewing machine with the stitch thread without any trouble. It is also possible to prevent pinholes that occur at the joint between the skin body and the sole of the skin during skin molding, and it is also easy to remove the skin from the skin molding die after skin molding. To provide a slash shoe that can surely and easily connect the portion and the ridge, and further reduce the risk that the load due to the bending of the shoe during walking is concentrated on the corner of the connecting portion and damages the shoe. With the goal.

[Means for Solving the Problems]

The present invention relates to a slash shoe having a skin in which a shoe bottom is integrally formed on a lower peripheral edge of a skin body, in which a connecting portion between the skin body and the shoe sole is curvedly formed to the inside of the shoe, and these skins are also formed. On the ridge peripheral portion extending from the connecting portion between the main body and the shoe sole to the upper edge portion of the shoe sole, a ridge whose skin side surface is a curved surface substantially corresponding to the curvature of the ridge peripheral portion is provided. It provides the characteristic slash shoes.

[Action]

In the slash shoe of the present invention, first, the skin and the ridge made of an arbitrary hue and material are individually formed in advance. Therefore, the skin and the ridge can be easily made different in color and different from each other, and the ridge sewn by the sewing machine stitch with the stitch thread in order to improve the design of the shoe can be used without any trouble.

At this time, this skin is formed by the slush molding method, and since the connecting portion between the skin body and the shoe sole is curved toward the inside of the shoe, the connecting portion between the skin body and the shoe sole during skin formation is formed. The generated pinholes can be prevented, and the skin can be easily removed from the skin molding die after the skin molding.

After that, a ridge is circumferentially provided by a predetermined means on the ridge peripheral portion extending from the connecting portion between the skin body and the shoe sole to the upper edge portion of the shoe sole, with the skin side surface facing the ridge peripheral portion side. .

At this time, since the skin side surface of the ridge is fitted and fixed to the curve of the ridge peripheral portion including the connecting portion, the lower peripheral edge portion of the skin body and the ridge can be surely and easily connected.

The slash shoe manufactured in this manner is used in the same manner as a general shoe, but as described above, since the connecting portion between these skin bodies and the sole is curved and formed inward of the shoe,
The load due to the bending of the shoe at the time of walking can be distributed to almost the entire connecting portion, and therefore the risk that the load at the time of walking is concentrated on the connecting portion and the shoe is damaged can be reduced.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings, but the present invention is not limited to this embodiment.

In describing this embodiment, a boot for men having a relatively short length will be taken as an example.

As shown in FIG. 1, the entire structure of the slash shoe according to the embodiment of the present invention includes a skin S in which a shoe bottom 20 is integrally formed with a lower peripheral edge 10a of a skin body 10.

The skin S is a body member of a slush shoe molded by the slush molding method, and the material of the skin S in this embodiment is soft polyvinyl chloride which is relatively soft so as to have good wearing comfort and walking ability. Although adopted, it is not necessary to limit to this,
Other thermoplastic synthetic resins can also be used.

The hue of the skin S is light gray in this embodiment, but the hue is not necessarily limited to this.
Any hue may be used.

In order to manufacture the skin S, first, a boot (not shown) is actually manufactured, and then a metal layer is formed on the surface of the boot (not shown) by an electroforming method or a metal vapor deposition method, and the metal layer is peeled off from the boot. Do not provide a hollow mold. In addition, the connecting portion between the skin body 10 and the shoe sole 20.
The molding location of S1 is curved toward the inside of the shoe.

Next, a molding material for the skin S (not shown) such as plastisol of vinyl chloride resin paste is poured into the hollow mold (skin molding die) (not shown), and then heated in the oven from the outside to the inner surface of the die. The sol is gelated from the contact portion of and is grown to a predetermined thickness. At this time, as described above, the connecting portion between the skin body 10 and the shoe sole 20.
Since the molding portion of S1 is curved toward the inside of the shoe, it is possible to prevent pinholes generated at the connecting portion S1 between the skin body 10 and the sole 20 during molding of the skin S, and the skin S
It is also easy to remove the skin S from the hollow mold after molding.

Next, the ungelled sol inside is discharged again, and the remaining gelled layer is heated and cooled to form a boot-shaped skin S as shown in FIG. 1 in which the skin body 10 and the shoe sole 20 are integrated. Then, again on the back surface of this skin S, the backing cloth B shown in FIG.
Is manufactured by expanding.

If the shoe sole 20 has a thick heel, for example, that portion may be added later.

Next, the feature of the configuration of the present invention is that the connecting portion S1 between the skin body 10 and the shoe sole 20 is also shown in FIG.
Is curved toward the inner side of the shoe, and the skin side surface 30a is almost on the ridge circumference S2 on the ridge circumference S2 that extends from the connecting portion S1 between the skin body 10 and the shoe sole 20 to the upper edge 20a of the shoe sole 20. This is a point in which a ridge 30 that is a curved surface corresponding to the bending of the installation portion S2 is provided around.

The connecting portion S1 here includes not only the connecting portion between the skin body 10 and the shoe sole 20 in the strict sense, but also the range between the skin body 10 and the shoe sole 20 near the connecting portion. It is a waste. The degree of curvature of the connecting portion S1 may be arbitrary. Further, in this embodiment, the connecting portion S1
To the upper edge portion 20a of the shoe sole portion 20, the ridge peripheral portion S2 is curved over almost the entire area, but it is not necessarily limited to this, and at least the connecting portion S1 may be curved.

As described above, the ridge 30 includes the skin body 10 and the shoe sole 20.
A strip-shaped member that is provided around the ridge peripheral portion S2 that extends from the connecting portion S1 to the upper edge portion 20a of the shoe sole 20, and the material in this embodiment is the ridge when the shoe S is bent with the skin S. Prevents cracking and peeling of 30 and has a ridge on a curved portion with a large bend such as a toe portion and a heel portion.
In order to flexibly accommodate around 30 skins, soft polyvinyl chloride having substantially the same hardness and the same material as the skin S is used, but it is not necessarily limited to this, and for example, a polyurethane elastomer resin may be used. Other thermoplastic synthetic resins such as, for example, may be adopted, and different materials may be used to improve the functionality of the shoe without having to use the same material as the skin S as in this embodiment.

Further, the hue of the ridge 30 of this embodiment is dark gray which is different from the hue of the skin S in order to improve the design of the shoe, but it is not necessarily limited to this and, for example, the hue of the skin S is The same light gray color or other hues may be used.

The skin side surface 30a of the ridge 30 in this embodiment is
Almost the entire surface is curved to the surface side in accordance with the shape of the ridge peripheral portion S2, but it is not necessarily limited to this, and any shape can be used as long as it matches the curve of the ridge peripheral portion S2. It may be curved within the range and to any degree. In this way, since the skin side surface 30a of the ridge 30 is aligned with the curvature of the ridge peripheral portion S2, the skin side surface 30a of the ridge 30 is familiar and fixed to the curve of the ridge peripheral portion S2 including the connecting portion S1, Therefore, the lower peripheral edge portion 10a of the skin body 10 and the ridge 30 can be joined securely and easily.

Further, in the center portion in the width direction of the ridge 30 of this embodiment, the third
As shown in the figure, stitch yarn 31
The sewing thread has been sewn on the machine to improve the design of the slash shoe, but this stitch thread is not always necessary.
No need to apply sewing stitch sewing with 31.

Further, as shown in FIG. 2, the tip of the ridge 30 of this embodiment on the side of the skin body 30b is provided with the ridge 30 and the skin body 10.
In order to improve the design of the shoe by giving a sharpness to the appearance of the connection with the outer edge, it is formed into an acute angle, and the skin main body side 30b of this ridge 30 is formed into an elliptical wall thickness in cross section. Thus, when the ridge 30 is lapped, it can be laid in a clean line without distortion along the curve of the ridge peripheral portion S2, but it is not necessarily limited to this, and for example, the fourth line can be used.
It may have any shape, such as that shown in FIGS.

Furthermore, the shoe sole side 30c of the ridge 30 in this embodiment.
Is relatively thick as shown in FIG. 3, and its surface is flat to improve the design of the shoe by exposing the flatness of the end of the ridge 30 on the sole side 30c. Although it is a surface, it is not necessarily limited to this, and may be a curved surface as shown in FIG. 7, for example.

Further, as the means for surrounding the skirt 30 around the skin S, the bonding method is adopted in this embodiment, but it is not necessarily limited to this. For example, the skin side surface 30a of the rim 30 is heated to provide the rim. Any method can be adopted such as a fusion bonding method in which the peripheral portion S2 is pressure-bonded.

As the adhesive used in the bonding method of this example, a polyurethane-based adhesive having good adhesiveness to polyvinyl chloride is adopted, but it is not necessarily limited to this, and for example, acrylic graft Polymer adhesives, neoprene adhesives, etc. can also be adopted.

The slash shoe shown in FIG. 1 manufactured in this way is used in the same manner as a general shoe, but as described above, the connecting portion S1 between the skin body 10 and the shoe sole 20 is curved to the inside of the shoe. Since it is formed, it is possible to disperse the load due to the bending of the shoe at the time of walking to almost the entire connecting portion S1, and therefore it is possible to reduce the risk that the load at the time of walking is concentrated on the connecting portion S1 and damages the shoe.

Although the embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and the present invention includes a design change and the like without departing from the scope of the invention.

For example, in the examples, relatively short men's boots were taken as an example, but it is not always limited to this, and for example, long men's boots, women's boots and short shoes are manufactured by the slush molding method. It can be used for any shoes.

[Effect of device]

In the slash shoe of the present invention, the skin and the ridge made of any hue and material are individually molded in advance, so that the skin and the ridge can be easily made different in color and heterogeneous, and the design of the shoe is improved. Therefore, the ridge stitched by the sewing thread with the sewing thread can be used without any trouble.

In addition, since the connecting part between the skin body and the sole is curved toward the inside of the shoe, it is possible to prevent pinholes from occurring at the connecting part between the skin body and the sole when forming the skin by the slush molding method. In addition, it is possible to easily remove the skin from the skin forming die after the skin forming.

Furthermore, since the skin side surface of the ridge is fitted to the curvature of the ridge peripheral portion including the connecting portion, the lower peripheral edge portion of the skin main body and the ridge are separated from each other when the ridge is provided around the ridge peripheral portion. The effect that the connection can be surely and easily obtained is obtained.

In addition, the slash shoes manufactured in this way are
Generally, it is used in the same way as shoes, but as described above, since the connecting part between the skin body and the sole is curved and formed inward of the shoe, the load due to the bending of the shoe during walking is applied to this connecting part. It is possible to disperse the load almost all over, so that it is possible to reduce the risk that the load at the time of walking is concentrated on this connecting portion and the shoes are damaged.
