Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shoe, and more particularly to an improvement in a shoe in which the front incision of the shoe is tightened and released by a band with a velvet hook-and-loop fastener mechanism.

In this type of shoes that are conventionally provided,
In general, bands have a weak waist, so when tightening the incision in the front part of the sleeve when wearing the band, the positions of the hook-and-loop fastener on the band side and the hook-and-loop fastener on the side of the sleeve do not necessarily match; This requires troublesome operations such as manual positioning. In addition, bands are generally made of fake leather, which lacks strength when used alone, so it is strengthened by backing the fabric, but such multi-layer structures are not only cumbersome and expensive to manufacture, but also cause separation, thread breakage, and They tend to fray, become deformed and warp during use, impairing their aesthetic appearance, and reduce the engagement strength due to a decrease in the engagement area of the fastener.

The present invention was made with the aim of eliminating such conventional problems. Namely, the present invention is a method in which the front incision of the headpiece is tightened and opened using a band equipped with a velvet hook-and-loop fastener mechanism. In this shoe, the band is made of a single molded elastomer having appropriate resilience and flexibility, and the band is attached to the inner surface of the tip of the band along the curved surface of the front surface of the shoe. The present invention relates to a shoe characterized in that one hook-and-loop fastener and the other hook-and-loop fastener attached to a clasp at a position opposite to the hook-and-loop fastener are fastened so as to maintain a state of contact and engagement at all times.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is the shoe body, and this shoe body 1
is equipped with a band 4 equipped with a velvet-type hook-and-loop fastener mechanism 3 in order to tighten and open the front incision 2 of the cover as in the conventional product. It is composed of one side fastener 3a attached to the inner surface and the other side fastener 3b attached to the cover at the opposite position.

The present invention provides a shoe of this type, in which the band 4 is composed of a single molded body of elastomer having appropriate resilience and flexibility;
Along the curved surface of the front surface of the shoe, one surface fastener attached to the inner surface of the tip of the band and the other surface fastener attached to the flap at the opposite position are in constant contact and engagement (see Figure 2). ) to hold
The band 4 is shaped by applying a general-purpose heat treatment (80 to
This can be easily achieved by heating at 100°C for 20 to 30 minutes.

1 and 2 show the state in which the front cutout 2 of the cover is tightened, and in this state, the hook-and-loop fastener mechanism 3
By performing the engaging and disengaging operations, the front incision portion 2 can be easily tightened and opened. In this case, in the present invention, the band 4 has excellent rebound elasticity peculiar to the elastomer that is the molding material, so the band 4 does not shift in its set position even during long-term wear. If you always maintain the correct setting position and simply press the band 4 toward the cover without visually checking each time, the hook-and-loop fastener 3a,
3b is engaged stably and reliably over a wide area at the set position, and the engagement operation is much easier than with conventional products that require visual confirmation.

In addition, since the band 4 has excellent rebound elasticity peculiar to elastomer, for example, as shown by the imaginary line in Fig. 2, if the band 4 is stored in a large arch shape against the rebound elasticity and then bounced back. The hook-and-loop fasteners 3a and 3b naturally engage with each other very quickly and reliably, achieving one-touch engagement, and also rapidly and snap-fitting, providing an effect that satisfies the taste buds.

Furthermore, since the band 4 is a single molded elastomer, it is less expensive than conventional products with a composite structure, and there is no risk of separation, thread breakage, or fraying.
Durability can be improved. Furthermore, the band 4 does not lose its shape or warp due to its excellent rebound elasticity, so there is no reduction in the engagement area of the hook-and-loop fasteners 3a and 3b, and the engagement strength remains unchanged and the beautiful appearance is maintained for a long time. It can be maintained for a long time.

In this way, in the shoes of the present invention, although the incision in the front part of the shoe is tightened and released by a band equipped with a hook-and-loop fastener mechanism, the operation when wearing the shoes is extremely simple and easy. At the same time, it has the advantage of being able to maintain its predetermined function and appearance indefinitely, thereby significantly improving the quality of this type of shoe.

In the present invention, various known materials can be used as the elastomer, but thermoplastic polyurethane elastomer can be particularly advantageously used. Thermoplastic polyurethane elastomer has good processability and can create any three-dimensional pattern by one-shot molding, and the direction of the groove pattern on the surface of the band 4 can be changed vertically, horizontally, diagonally, etc. By setting it arbitrarily, the rebound elasticity and flexibility can be adjusted. Furthermore, the hook-and-loop fastener 3a can be integrally attached to a predetermined location of the band 4 during molding. Polyurethane elastomer also has a long lifespan because it is less prone to seam allowance breakage due to sewing thread.
Also, the characteristics of the material make it easy to move the hands.

Such thermoplastic polyurethane elastomers include Pantex T (manufactured by Dainippon Ink Chemical Co., Ltd.),
Elastran (manufactured by Nippon Elastran Co., Ltd.), Paraprene (manufactured by Nippon Polyurethane Industry Co., Ltd.), Peresene (manufactured by Kasei Atupjiyon Co., Ltd.), PUC (Dainichisei Chemical Industry Co., Ltd.)
It is commercially available under the trade names of Takeda Pharmaceutical Co., Ltd.) and Takerakku (Takeda Pharmaceutical Co., Ltd.) and is easily available.
