Description

[Detailed description of the invention] (Field of industrial application) This invention relates to footwear boots. More specifically, the present invention relates to the structure of a boot in which the lining fabric of the foot portion and the cylindrical portion, and the cylindrical portion and the foot portion constituting the boot are respectively joined.

(Prior Art) In the structure of conventional boots of this kind, as shown in FIG. There is a structure in which the material of the cylindrical portion 2 is made into a bag shape as shown in FIG. However, these conventional boot structures have various problems.

(Problems to be solved by the invention) In other words, in the boots with the structure shown in Fig. 2, the cylindrical portion is simply made of one layer, so the heat retention, which is the original function of the boot, is not sufficient. Since the part is pasted and joined to the outside of the foot, it has a step-like appearance, which has the disadvantage of detracting from the aesthetics. Further, in the boot having the structure shown in FIG. 3, even though the cylindrical portion has a bag-like shape, it cannot fully exhibit the function of the bag-like structure. In other words, in the two-layered bag-like wall, in its current state, the two layers (two sheets) are in close contact with each other and are not separated, and as a result, there is no space inside the bag, so the heat retention effect of air is It's as good as nothing. Moreover, the joint part connects the layer at the end of the leg part 1 to the two layers of the cylindrical part 2.
Since the edges of the pieces are sandwiched and joined, the outer appearance is uneven, spoiling the aesthetic appearance, and the inner surface is uneven, which makes it hard to get rid of the discomfort when worn. .

This invention was developed by paying attention to the structure of the conventional boot as described above, particularly the structure of the cylindrical portion, the joints thereof, and the joint structure, and devising various ideas.

(Means for Solving the Problem) For this reason, in this invention, the cylindrical part of the boot is joined to the foot part at two places. That is, in a boot in which the foot part 1 and the cylindrical part 2 are made of different materials, the lining fabric 3 of the boot is extended above the foot part 1 and its end is joined to the end of the cylindrical part.
This problem is solved by folding the other end of the cylindrical part 2 and joining it to the leg part 1 to make the cylindrical part 2 into a bag-like shape. In this invention, the materials of the foot part 1 and the tube part 2 are different depending on the material of which the boot is made, but they need to be different. In other words, in general, a slightly harder material such as rubber or leather is suitable for the foot part in terms of durability and comfort, whereas a slightly softer material such as leather, cloth, or leather is suitable for the tube part. As appropriate, the combinations of different materials can be diversified. Moreover, it can exhibit an excellent aesthetic sense in terms of variation in color, design, etc. There are no restrictions on the structure of the lining fabric 3, such as woven fabric, knitted fabric, non-woven fabric, etc., and the material is polyurethane foam,
A combination with a heat insulating material such as a boa is suitable.

The joining structure of the cylindrical portion 2 in this invention is as follows:
First, the lining fabric 3 of the boot is provided to extend above the foot 1, and the extended end thereof is preferably approximately 1/2 the length of one side of the bag-shaped 2 of the cylindrical portion 2, but there is no particular limitation. In this case, it is preferable that the seam allowance 3 is contained inside the tubular bag-shaped portion 2. By doing so, the bag-shaped portion 2 is constantly inflated and encloses air, which further enhances the heat retention effect.

Further, it is preferable that the other end of the cylindrical portion 2 and the end 4 of the foot portion 1 be joined so as to overlap the stepped portion 5. This is because by doing so, the boots are superior in appearance and comfort.

(Function) In the boot of this invention, the joints of the cylindrical portion 2 are not at the same place, but are distributed at two places, so the stress of bending can not only be softened and dispersed, but also the joints If the part is sewn without using glue, there will be no hardness in that part, making it more comfortable to wear.
Excellent feel to the feet. In addition, by using a waterproof and breathable material for the cylindrical part 2 and emphasizing its differences from the material composing the foot part 1, it is possible to diversify the selection and create an excellent aesthetic sense with colors and patterns. It can be demonstrated. Furthermore, since the cylindrical part 2 of the boots of this invention is in the form of a bag 2, it serves as a place for dissipating stuffy air inside the foot when worn, and at the same time,
In cold weather, the inside of this bag is filled with air, which provides excellent heat retention. Moreover,
Focusing on this heat-retaining effect, when a heat-retaining material such as polyurethane foam or boa is used as the lining cloth, a further heat-retaining effect can be exhibited by making the length of the lining fabric longer. However, when looking at the boot as a whole, the joint between the cylindrical part and the foot part has a step and is sewn together to form an integral joint structure, which gives it a beautiful appearance. It can be folded back in length, making it easy to create a pair of boots or a pair of short boots.

(Example) Hereinafter, an example of this invention will be described in detail based on the accompanying drawings.

Fig. 1 is a side sectional view showing the structure of the boot of this invention, Figs. 2 and 3 are side sectional views showing the structure of the conventional boot, and Fig. 4 shows the foot and tube parts in Fig. 1. A partially enlarged cross-sectional view showing the bonded state of each is shown.

In the figure, 1 is the foot part of the boot, 2 is the tube part, 2 is the bag-shaped part of the tube part 2, 3 is the seam allowance between the foot part 1 and the tube part 2, 3
4 indicates a seam allowance between the lining fabric 6 and the tube portion 2, 4 indicates a serpentine end portion of the foot portion 1, and 5 indicates a stepped portion for joining the tube portion 2 to the end portion 4 of the foot portion 1.

In the conventional boot construction shown in FIG. 2, the barrel 2 is stitched to the foot 1, in particular to the end 4 of the foot 1, with an overlapping seam on the outside. Similarly, in FIG. 3, each end of the two bag-shaped parts 2 is joined to the end part 4 of the foot part 1 by pinching and sewing. For this reason, when looking at the joint part from the outside of the boot, the cylindrical part 2
Since the thickness of the foot protrudes outward from the foot, it forms a step and spoils the aesthetic appearance. The same applies to the case of FIG. Moreover, even though the boot in Figure 3 forms a two-layer bag-like object, it does not exhibit this bag state, but the two walls of the bag overlap each other, and the inside of the bag does not exhibit this bag state. The structure makes it difficult for air to be trapped inside. On the other hand, in the structure of the boot of this invention shown in FIG. has been done. Therefore, the two walls of the bag-like part 2 are constantly isolated from each other and do not come into close contact with each other, so the bag-like part 2 always contains air, so the air has a higher heat retention effect. is brought about. In this case, the lining cloth 6
The position of the seam allowance 3 at the joint between the tubular part 2 and the tubular part 2 is within the length of one turn of the bag-shaped part 2, and it is particularly appropriate that the seam allowance 3 be located at a position approximately half that length. This is because the seam allowance 3 is located approximately at the center of the bag-shaped portion 2, which impedes the mutual adhesion of the bag walls. On the other hand, the tube part 2 and the end part 4 of the foot part 1 are joined by providing a stepped part 5 and sewing them together.
The appearance is smooth and aesthetically pleasing with no irregularities.
In other words, the upper end of the lace member consisting of two pieces, the lace front 7 and the lace back 8, is slightly longer than the lace front material, and the cylindrical portion 2 is stacked on the stepped portion 5 to form the upper end of the leg portion 1. The two parts are sewn together so that the cylindrical part 2 is flat in appearance. The structure of the boot of this invention can be selected and used in appropriate combinations of various materials.

(Effects of the invention) As described above, according to this invention, the cylindrical part 2 always has air inside, so it has a heat-retaining effect, and the lining cloth 6 is made of a heat-retaining material such as polyurethane foam. And its heat retention effect is further improved. Moreover, since the tube part 2 is bag-shaped, the stuffy air inside the foot part 1 of the boot is dispersed from there, thereby preventing the feet from getting stuffy due to perspiration and maintaining comfort. Furthermore, since the material of the tube part is waterproof and breathable, it is possible to diversify the foot part 1 and the tube part 2 by appropriately combining different materials. Due to the flexibility of the pouch-like part, the boots can be folded outward or inward at will, and the structure of a pair of boots combines the functionality of both long boots and short boots.
