Description

[Detailed description of the device]

[0001]

[Industrial applications]

 According to the present invention, the mouth opening is folded back to the outside without losing its shape, and the covering end of the tubular member on the boot body forms a natural continuous surface. The present invention relates to boots that allow easy foot insertion.

[0002]

[Problems to be solved by conventional techniques and devices]

 For example, in slush molding boots, a paste such as PVC is poured into a tubular shoe-shaped mold, the surrounding area is heated for a short time to gel the paste, and then excess paste that is not gelled is removed from the mold. After it is discharged into the mold, it is further heated to completely solidify the gelled skin left in the mold and then molded. By the way, since the mold for slush molding is expensive, when changing the surface shape of the boot, the upper end of the boot after molding is cut off and a different material (for example, synthetic leather, knit fabric, A woven fabric, a non-woven fabric, etc.) is used to cover a tubular member so as to diversify the design or to improve the cold protection and heat retention.

However, when a normal tubular member is covered with a tubular member and joined using a bias tape or a means such as sewing, swelling occurs at the end of the tubular member covering the boot body. , Appearance may be impaired. Therefore, as shown in the partial enlarged cross-sectional view of the mouth opening portion of FIG. 4, a step P is formed at a predetermined height position of the skin tubular portion 71 so as to reduce the thickness of the upper portion of the skin tubular portion 71. It is also attempted to cover the thinned portion with the tubular member 73 to realize a natural surface shape. In FIG. 4, the backing cloth 72 is extended above the upper end position a ₂ of the skin tubular portion 71, one edge of the tubular member 73 is sewn to the edge of the backing cloth 72, and the other end of the tubular member 73 is sewn. Edge of the skin tube portion 71 is brought into contact with the step P of the skin tube portion 71.

However, in the above case, the seam allowance Q between the back cloth 72 and the tubular member 73 is contained in the bag portion J formed by the back cloth 72 and the tubular member 73, and the seam allowance Q is shown in FIG. _As shown in Fig. ₁ , there is an inconvenience that it appears on the outer surface of the boot and impairs the appearance of the boot. Further, at the upper end position a ₂ of the skin cylinder portion 71, the corner of the upper end of the skin cylinder portion 71 may appear as a bulge on the surface, and in this case also, the appearance of the boot is impaired.

In order to eliminate such inconvenience, the inventor of the present invention proposes a boot having a boot structure as shown in a partially enlarged sectional view of FIG. 5 (A) as Japanese Patent Application No. 4-8094. ing. In the boot having the boot structure shown in FIG. 6A, a step P that reduces the thickness of the skin is formed at a predetermined height position of the skin cylinder 81, as in the case of FIG. The thin portion of the portion 81 is tapered toward the edge of the skin cylinder portion 81. Here, the tubular member 83 is configured by stitching one edge of the tubular member element 83a and one edge of the tubular member element 83b, and the other edge of the tubular member element 83b is a back side. The upper end of the cloth 82 is sewn, the other edge of the tubular member element 83a abuts on the step P, and the tubular member 83, the skin tubular portion 81, and the back cloth 82 are sewn along the step P. . In this boot, seam allowance Q of the cylindrical member elements 83b and the back fabric 82 than the upper end position a ₂ skins tubular portion 81 is provided below, thereby never seam allowance Q appears on the outer surface of the boot . Further, since the thin portion of the skin tubular portion 81 is formed in a taper shape as described above, the corner of the upper end of the skin tubular portion 81 does not appear on the surface, and a natural appearance can be exhibited. it can.

By the way, there is also proposed a boot in which a tubular member is attached to the tubular portion of the main body, the boot being used by folding the tubular member back to the outside of the mouth (for example, Japanese Utility Model Publication No. 3-42801). See the bulletin). However, since the boot described in this publication and the boot shown in FIGS. 4 and 5A described above are designed to be used by extending the tubular member upward, the tubular member is folded back to the outside. The following inconveniences occur when used as follows.

That is, in the boot having the boot structure shown in FIG. 4, when the tubular member 73 is folded back to the outside in the vicinity of a ₂ , the back cloth and the seam allowance Q appear on the outer surface of the boot, and the appearance is degraded. There's a problem. Although not described with reference to the drawings, the same problem occurs in the boot described in the above publication. Further, in the boot having the boot structure shown in FIG. 5 (A), since the skin tubular portion 83 is not suitable for folding back, the tubular member 83 cannot be folded back below a ₂ . Therefore, the skin tubular portion 81 is folded back at the upper end position a ₂ , but in this case, since the thin portion of the skin tubular portion 81 is tapered, the skin tubular portion 81 tries to be folded back together with the tapered portion. Therefore, it is not easy to fold back the tubular member 83 at an appropriate position (that is, the upper end position a ₂ of the skin tubular portion 81). Even if the tubular member 83 can be folded back to the outside at the position a ₂ , the seam allowance Q with the back cloth 82 is the seam R between the tubular member elements 83a and 83b (located at the top of the skin tubular portion 83). However, there is a problem that it warps outward as shown in FIG. 5 (B).

Further, generally, when the boot is mounted, the foot is inserted into the boot without grasping the mouth opening, and the elasticity of the material of the boot cylinder is used to keep the foot inside the boot. Actually, it is often done to operate with and push it completely inside. For example, in the boot having the boot structure shown in FIG. 4, since the thin portion above P of the skin cylinder portion 71 is not tapered, the skin cylinder portion 71 itself is not inferior in shape retention. However, since the seam allowance Q is formed inside the mouth (in other words, not formed at the upper end of the mouth), the shape retention of the tip of the mouth is poor. The same applies to the boot described in the above publication. Further, in the boot having the mouth opening structure of FIG. 5 (A), since the suture portion R is formed at the upper end of the mouth opening, the shape retention of the tubular member 83 itself is not so low, but the skin tubular portion 81 is thin. The shape retention of the part is poor.

For this reason, in the boot as described above, if a person tries to put in the foot without gripping the mouth opening portion, the shape retention of the foot opening portion is poor, so that the rear end of the tubular member is located inside the foot opening. You may be caught and unable to wear it. In particular, in the case of elderly people, infants, and children of the younger age group, they do not wear by grasping the boots, but wear them only by the movements of their feet, or even their feet inside the boots. Since the boots are often worn without being operated, the boots described above are not suitable for the elderly or children's shoes. Although the slush-molded boot has been described above, the same disadvantage occurs with an injection-molded boot having the same mouthpiece structure as described above.

The present invention has been proposed to solve the above-mentioned problems, in which the mouth opening is folded back to the outside without losing its shape, and the end of the tubular member covering the boot body is naturally continuous. An object of the present invention is to provide a boot that is configured to form a surface, has high heat retention, and can be easily put into the foot even for elderly people.

[0011]

[Means for Solving the Problems]

 The boot of the present invention has been proposed to achieve the above-mentioned object, and is provided near the boundary between the main body foot and the main body tubular part or in the middle of the main body tubular part, and is mounted above the main body tubular part. A step is formed to reduce the thickness to a substantially uniform thickness, one edge of the tubular member is joined to the backing cloth inside the main body tubular portion, and the other edge of the tubular member is joined to the step. The tubular member is joined so as to abut, and covers the thin portion of the main body tubular portion and forms a bag portion between the joint portion with the back cloth and the upper end of the main body tubular portion. It is characterized by being folded back to the outside.

The boot of the present invention can be applied to either a slush molded boot or an injection molded boot. However, since the configuration of the present invention is suitable for wearing during snowfall or in cold regions, It is preferably applied to slush molded boots with high waterproofness.

[0013]

[Action]

 In the boot of the present invention, since the tubular member covers the thin portion of the main tubular portion, the boundary portion between the tubular member and the skin forms a natural continuous surface. In addition, the portion above the stepped portion of the main body cylindrical portion, which has a substantially uniform thickness and is thin, has an appropriate shape retention property. As a result, when the bag portion formed between the back cloth and the upper end of the main body tube is folded back to the outside, the tubular member is not folded back along with the upper part of the main body cylinder, and is not attached to the upper end portion of the main body cylinder. Folds along.

By folding back the bag portion, the mouth opening portion has a quadruple structure of the tubular member material, so that the shape retaining property of the foot opening portion is further enhanced. Further, the heat retaining effect of the mouth opening portion is improved, and the effect of preventing cold and heat can be enhanced by enlarging the folded portion (enlarging the bag portion).

Usually, the tubular member is made of a material different from the material of the boot body (for example, synthetic leather, knitted fabric, woven fabric, non-woven fabric, or the like in which urethane foam or the like is laminated). A unique appearance is performed. The tubular member is made of a heat insulating material (for example, knitted fabric, woven fabric, non-woven fabric made of wool, or synthetic leather or synthetic fiber knitted fabric, woven fabric, nonwoven fabric laminated with urethane foam, etc.) In the case of the above configuration, the above-mentioned cold protection and heat retention effects are further improved.

Further, in the boot of the present invention, since the main body cylinder portion reaches the uppermost portion of the mouth opening, it has a good restoring force. As a result, for example, when the foot is inserted into the tube without gripping the mouth opening, even if the heel of the foot bends the mouth opening inward or crushes the rear part of the boot, the body tube is restored. The force naturally pushes the foot into the boot. In addition, since the tubular member has a single-layer structure inside the skin tubular portion, the foot can be easily inserted.

It should be noted that, for example, when snowing, the tubular member can be used as a snow protection boot by extending upward from the shoe opening and covering the legs above the shoe opening. Even when used in this manner, the tubular member exerts a cold protection effect.

【Example】

 FIG. 1 is a diagram showing an embodiment in which the structure of the boot of the present invention is applied to a slash molding boot. FIG. 1A is an external view of the boot body, and FIG. 1B is a cross-sectional explanatory view of the boot.

As shown in FIG. 1 (A), the boot body (skin 2) is composed of a main body foot portion (skin foot portion 21) and a main body tubular portion (skin tubular portion 22) that are integrally formed. In the embodiment, the step P is formed at the boundary between these. The thickness T ₂ of the skin tubular portion 22 (this thickness is substantially uniform) is formed thinner than the thickness T ₁ of the skin foot portion 21. In order to prevent the corners of the skin cylinder from appearing on the outer surface of the boot, the boot in which the thin part of the cylinder is tapered (see Fig. 5 (A)) requires delicate heating control of the mold. Becomes On the other hand, in the boot according to the present invention, even if the thickness of the skin tubular portion 22 is substantially uniform, the corners of the skin tubular portion do not appear on the outer surface, and therefore the skin tubular portion need not be tapered. Therefore, delicate heating control of the mold is not required.

FIG. 1B illustrates a boot 1 manufactured using the skin 2. In FIG. 1B, a heel block 31 is embedded in the heel portion and an insole board 32 is laid in the shoe sole portion. In addition, a back cloth 42 sewn with a midsole cloth 41 is attached to the inside of the skin of the skin foot portion 21 and the inside of the tubular portion 22. One edge of the tubular member 5 is sewn to the back cloth 42 at the inner side of the skin tubular portion 22 (position lower than the upper end position) (the seam allowance is indicated by Q), and the other edge is the boot. 1 is in contact with the step P on the outer surface. The tubular member 5 is attached to the thin portion of the skin tubular portion 22. The tubular member 5 is sewn to the skin tubular portion 22 along the contour of the step P (the sewn portion is indicated by L). With this structure, the skin tube portion 22 forms the bag portion J between the stitched portion with the back cloth 42 and the upper end of the skin tube portion 22. The bag portion J is folded back to the outside of the mouth opening, as shown in the figure, during normal wear.

Since there is no seam allowance in the bag portion J, when folded back to the outside, the hem of the folded portion bends outward and the appearance is impaired (see FIG. 5B). The tubular member 5 is made of synthetic leather, knitted fabric, woven fabric, non-woven fabric, or the like in which urethane foam or the like is laminated. FIG. 2 is an external view of the boot 1 configured as described above.

In the above embodiment, the step P is formed in the vicinity of the boundary between the skin foot portion 21 and the skin cylinder portion 22, but for example, the cylinder portion is shown in FIGS. 1 (A), 1 (B) and 2. In a boot longer than the boot 1, since the step P is determined by the mold, in order to make the boot long, the cut position at the upper end of the skin tubular portion is increased and the tubular member is considerably lengthened. Also, when the folding width of the collar is changed with the same length, the tubular member may be lengthened to widen the folding width and shortened to narrow the folding width.

In the above-mentioned embodiment, the upper end of the skin cylinder is cut in a flat state, but as shown in FIGS. 3A and 3B, a thickness can be formed at the edge. (A) of the same figure shows an overall view of the skin, and (B) of the same figure is an enlarged cross-sectional explanatory view of the mouth part of the boot manufactured using the skin of (A). In FIGS. 3A and 3B, the same code elements as those used in FIGS. 1A and 1B are the same as those described in FIGS. 1A and 1B. 2A and 2B show a state in which a bead M is formed on the upper end of the skin cylinder portion 22. With this structure, the shape retention of the mouth opening is further enhanced.

[0024]

[Effect of device]

 Since the present invention is configured as described above, the following effects can be obtained.

(1) Since the portion above the level difference of the main body cylindrical portion and having a substantially uniform thickness has an appropriate shape-retaining property, it is formed between the back cloth and the upper end of the main body cylindrical portion. When the bag portion is folded back to the outside, the tubular member is not folded back along with the upper portion of the main body tubular portion, and can be easily folded back along the upper end portion of the main body tubular portion.

(2) Since the mouthpiece portion has a quadruple structure made of a tubular member material, the shape retention property of the mouthpiece portion is further enhanced. In addition, the heat retaining effect of the mouth opening is improved, and the effect of preventing cold and heat can be enhanced by enlarging the folded-back portion (enlarging the bag portion).

(3) Due to the elasticity of the main body tubular portion reaching the mouth opening, the tubular portion has a good restoring force. As a result, for example, when the foot is inserted into the tube without gripping the mouth opening, even if the heel of the foot bends the mouth opening inward or crushes the rear part of the boot, the body tube is restored. Due to the force, the foot naturally goes inside the boot. In particular, due to the improvement in the above-mentioned foot insertion, there is little danger that the tubular material will bend at the tip of the toe or heel, and will fall due to being caught in or caught in the inside of the boot. Is also suitable.

(4) Since the tubular member can be extended upward from the shoe opening portion and cover the leg portions above the shoe opening portion, it can be used for snow protection.

(5) The boundary between the tubular member and the skin forms a natural continuous surface.
