[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION This invention relates to a sandal insole.

[0002]

2. Description of the Related Art In conventional sandals, an insole and a band are made separately. Further, the conventional insole has a shape that usually matches the shape of the outsole.
In the case of a sandal with a thong-like band, the rear ends of the left and right band pieces are interposed and fixed between the insole and the outsole, and the front ends of both band pieces are inserted into the toes of the insole. It was inserted through the hole and fixed by being interposed between the insole and the outsole.

[0003]

[Problems to be Solved by the Invention] However, if the insole and the band are made separately, both the front end and the rear end of the band must be fixedly interposed between the insole and the outsole, respectively. It was troublesome. In addition, if the shape of the insole matches the shape of the outsole, and if the rear ends of the left and right band pieces are arranged on the outside of both edges of the insole, between the rear end of the band and the side of the foot. Since there was a gap in the band, the band did not fit on the foot, and in this respect, the conventional sandals with a thong band were not comfortable to wear.

An object of the present invention is to provide a sandal insole which solves all the above problems.

[0005]

This invention is an insole used for a sandal with a thong-like band having band insertion holes in the toes, and the insole is inserted at required locations on both left and right edges of the insole. The edge portion is formed, and a pair of left and right band pieces are integrally provided on the bay edge portion in a front oblique wing shape when seen in a plan view.

[0006]

According to the present invention, the bay edge portions are formed at required positions on the left and right edges of the insole having the band insertion holes in the toes, and the pair of left and right band pieces are formed at the bay edge portions. Since it is integrally provided in the shape of a front slanted wing when viewed from the plane, both band pieces are bent in an arch shape, each end is inserted into the band insertion hole, and it is fixed by interposing between the insole and the outsole. As a result, sandals with a thong band are inevitably obtained. Moreover, since the left and right band pieces are integrally provided on the left and right edges of the insole to enter the bay, there is no step at the boundary between the two band pieces, and both band pieces wrap around the sides of the foot. It can have a curved shape.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

The insole (1) (on the right side of the sandals) with a thong-like band shown in FIGS. 1 to 3 is provided with vertically long band insertion holes (4) in the toes, and the middle of the left and right edges is almost the same. A bay edge (5) (6) is formed from the rear to the back, and a pair of left and right band pieces (2) are formed on these bay edges (5) (6).
(3) is integrally provided in a front oblique wing shape when viewed from the plane.

In the figure, (7) is an insole (1) and left and right band pieces (2)
One sheet of synthetic leather common to (3), (8) made of cardboard with sponge upper cushioning material (9) bonded to the insole (1) of the back side of the surface coating (7) Insole core layer, (10) is insole core layer (8)
Gauze back coating layer adhered to the back surface of (11) and (12) are synthetic leather back coating layers bonded to the left and right band pieces (2) and (3) of the back surface of the surface coating layer (7), respectively. (13) (14) is band piece (2)
With the end face of (3) left, the edges of the core layer (8) and the front and back coating layers (7), (11) and (12) in the insole (1) and both band pieces (2) and (3) are laterally U-shaped.
Synthetic leather front and rear edge members wrapped in shape and sewn, (22)
Reference numeral (23) denotes a rivet insertion hole formed near the ends (2a) and (3a) of the left and right band pieces (2) and (3).

2 and 3, the left and right band pieces (2) and (3) are bent in an arch shape, and the respective end portions (2a) and (3a) are insole.
It shows a state in which it is inserted into the band insertion hole (4) of (1) from the front side, bent outward, and fixed to the back surface of the insole (1) by adhesion. In the figure, (15) is a rivet that is provided through the rivet insertion holes (22) and (23) of the left and right band pieces (2) and (3). (3) is formed integrally, and a front part (16) for inserting the crotch of the big toe and the forefinger is formed.

4 and 5 show a sandal (17) completed by using the insole according to the present invention.
The underside of the insole (1) in the state shown in Figure 1, that is, the gauze back coating layer (10) and the ends (2a) of the left and right band pieces adhered to it.
The back surface of (3a) is adhered and fixed to the surface of the foam synthetic resin book bottom (18). In the sandals (17) above, of the left and right band pieces (2) (3), the bay entry edge (5) of the insole (1)
The part between (6) and the left and right edges of the outsole (18) is not glued to the outsole (18), so wrap it around from the bottom according to the shape of the side of the foot. It can have various curved shapes.

6 and 7 show another embodiment of the front part formed on the left and right band pieces (2) and (3). In the one shown in FIG. 6, the front and back portions (19) are formed by horizontally stitching the upper and lower portions of the left and right band pieces (2) and (3) near the band insertion holes (4). In addition, as shown in FIG. 7, before the end portions (2a) and (3a) of the left and right band pieces (2) and (3) are inserted into the band insertion hole (4),
The front part (21) is formed by being folded in two and inserted into the vinyl tube (20).

In the above embodiment, the presence of the single synthetic leather surface covering layer (7) common to the insole (1) and the pair of left and right band pieces (2) and (3) makes the insole (1) Both band pieces (2) (3) are integrally provided, but it is not limited to such a structure, in short, the insole (1) and both band pieces (2) (3) are connected. If you have.

[0014]

According to the present invention, it is inevitable that both band pieces are bent into an arch shape and their ends are inserted into the band insertion holes and fixed between the inner bottom and the outsole. Since a sandal with a thong-like band can be obtained, there is an advantage that the bonding process of the band pieces to be worn on the insole and the outsole can be saved by one step as compared with the conventional sandals in which the insole and the band are made separately. It is economical because it requires less material and processing costs.

Further, since bay-entry edge portions are formed at required positions on both left and right edges of the insole, and left and right band pieces are integrally provided at these bay entry edges, the insole and left-and-right band pieces are provided. There is no step at the boundary between the two, and both band pieces can have a curved shape that wraps around the side of the foot. Therefore, in the sandals obtained by using this device, the band fits the foot well and is very comfortable to wear.
