Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a lining fabric for boots that is comfortable to wear, is resistant to unraveling, and has excellent durability.

[Conventional technology]

Generally, the inner surface of boots made of rubber or vinyl has a lining fabric that prevents the foot from coming into direct contact with the boot material and also serves to absorb sweat that is generated when the boots are worn. It is installed.

As shown in FIG. 3, such a boot lining fabric is made by cutting out an irregular square piece 8 having a concave arc-shaped edge 8a on the lower side and an irregular half-moon-shaped piece 9 having a concave arc edge 9a on the upper side, respectively, using a cutting die. Prepare the punched lining material, and cut the irregular square piece 8 and the irregular half-moon piece 9.
along the central polygonal lines 8c and 9c, respectively.
Bend 180 degrees to form a concave arc-shaped edge 8 of an irregular square piece 8
a and the concave arcuate edge 9a of the odd-shaped half-moon-shaped piece 9 and stitch them together to integrate both pieces 8 and 9,
The two side edges 8b of the odd-shaped rectangular piece 8 and the two side edges 9b of the odd-shaped half-moon piece 9 were sewn together using a lock sewing machine to form a sock shape as shown in FIG. 4.

[Problem that the invention attempts to solve]

However, when the boot lining fabric as shown in FIG.
The seam part a and the seam part from the two side edges 8b to 9b, which are sewn by a lock sewing machine, intersect in a criss-cross pattern, and as a result, when the lining material is made of a relatively thick material, a large number of sewing threads are formed. There was a problem in that the protrusions gathered together and became hard, making them extremely uncomfortable to wear, and the protrusions were likely to tear due to strong pressure and friction from the heel.

[Means for solving problems]

As a result of intensive research in order to solve the above-mentioned problems with the conventional lining fabric for boots, the inventor of the present invention did not punch out the lining fabric into two separate pieces (upper and lower), but instead punched out the lining fabric on the left and right sides of the heel part of the lining fabric itself. Cut out the other two pieces of heel cover in a symmetrical shape, and abut the other two pieces of heel cover on both of the cut parts, suture the abutting edges and the cut edges of the lining fabric body, and also stitch the lining fabric body along the longitudinal center line. If the fabric is bent and the left and right edges are sewn together, the stitched part located at the rearmost part of the heel is only a straight line, so a boot lining fabric that is comfortable to wear and does not easily unravel can be obtained. After researching this, they completed the present invention.

That is, the present invention consists of two pieces of similar shape, each having a lining fabric body that is bilaterally symmetrical and has a cutout at the heel, an edge that abuts the cutout edge, and a convex arc-shaped edge on the opposite side of the edge. The lining fabric body is bent along its longitudinal center line, and its left and right edges are aligned and sewn together except for the upper end and the cut edge. The two pieces of the heel cover are sewn together with their respective convex arched edges aligned, and the abutting cut edges of the lining fabric main body and the two pieces of the heel cover are sewn together to form a sock shape. The object of the present invention is to provide a lining fabric for boots, which is characterized in that:

〔Example〕

Hereinafter, one of the lining fabrics for boots according to the present invention is shown in the drawings.
Examples will be described in detail.

Fig. 1 is a front view of an embodiment of the main body and heel cover punched out with a cutting die to produce the lining fabric for boots according to the present invention, and Fig. 2 is a front view of an embodiment of the main body and heel cover of Fig. 1. FIG. 2 is a side view of one embodiment of the manufactured lining fabric for boots according to the present invention.

In the drawings, reference numeral 1 denotes a resection portion 1b that is symmetrical with respect to the longitudinal center line 1a, and has semicircular resection edges 1d and 1e in which the heel portion is resected in a semicircular arc shape;
1c is the main body of the lining fabric, and the shape of the cut edges 1d and 1e is not limited to a semicircular shape, but may be a dogleg shape or the like, as long as it is left-right symmetrical. The material of this lining body 1 is that the surface that comes in contact with the foot is made of a fabric that feels good on the skin, the outer side is made of a synthetic resin foam sheet that has good elasticity and sweat absorption, and the outer side is made of rubber that is the lining material. A three-layer structure made of fabric is preferably used so that vulcanization and adhesion are easy. 2 and 3 are edges 2 that abut the cut edges 1d and 1e of the lining main body 1, respectively.
a and 3a and the convex arcuate edges 2b and 3b on the opposite side
They are heel covers of mutually similar shapes. The convex arc-shaped edges 2b and 3b of the heel covers 2 and 3 are doglegged, and the curved portions have a relatively large arc shape. This is preferable because it can be easily formed into a sock shape when sewn together, and can be easily fitted to the heel. 4 aligned with this
are the left and right edges of the lining body 1 and the heel covers 2 and 3.
The convex arcuate edges 2b and 3b are lock-stitched with a suture thread. 5 is the cut edge 1d of the lining body 1
This is a suture thread that stitches the contact portions of 1e and the edges 2a and 3a of the heel covers 2 and 3. 6 and 7 are intersections where the suture thread 4 and the suture thread 5 intersect in a criss-cross pattern, the bottom intersection 6 is located at the arch of the foot, and the upper intersection 7 is located at the rear of the foot. It is preferable for the shoes to be comfortable to wear.

[Effect]

The lining fabric for boots according to the present invention having such a structure is
As shown in FIG. 1, the lining fabric main body 1 is manufactured by punching out a shape in which left and right symmetrical cutouts 1b and 1c are provided on the left and right sides of the heel part, and the cutouts 1b and 1c are cut out. Two pieces of similar-shaped heel covers 2 and 3 having edges 2a and 3a that abut edges 1d and 1e, respectively, are separately punched out using a cutting die, and cut edges 1d and 1e of lining fabric body 1 and heel covers are produced. 2
The edges 2a and 3a of 3 and 3 are butted against each other and sewn together with the suture thread 5 in a staggered stitch, and the left and right edges are aligned and folded along the longitudinal center line 1a of the lining body 1 to form the aligned left and right edges. Aligned convex arcuate edges 2b and 3b of the heel covers 2 and 3
are sutured with suture thread 4 except for the upper end surface to form a sock shape and complete.

The lining fabric for boots according to the present invention thus formed into a sock shape can be hung into a mold, and then a rubber sheet can be attached to the outer surface and vulcanized in the same manner as in the past to manufacture rubber boots. It can be done.

〔effect〕

The lining fabric for boots according to the present invention as detailed above is
Before being sewn into a sock shape, the lining material is separated into the lining material itself and two pieces of heel cover that cover the heel, and when these are sewn together to form a sock shape, there is a layer at the back of the heel. The sutures placed are only straight sutures,
Since there is no hard protrusion caused by the cross-shaped seams of conventional products, it is comfortable to wear, and the protrusion is less likely to come loose due to strong pressure and friction from the heel, making it highly durable. The sutures between the cut edge of the cut out part of the lining body and the edge of the heel cover, which is the sutured part that comes into contact with the collar, are stitched together by aligning these lines, so there is no protruding part, so it is comfortable to wear. In addition, if the intersection of the staggered seam and the aligned and lock-stitched seam of the lining fabric and heel cover is placed on the arch or back of the ankle, the hard protrusion will protect the foot. Since it is placed in areas that do not come in direct contact with the wearer, it can be more comfortable to wear, and its practical value is extremely great.
