[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an injection molded shoe covering material.

[0002]

[Prior Art]

 Conventionally, as the California method cover material for injection-molded shoes, the toe of the cover is curved to form a curved surface, so the length of the lower peripheral edge of the cover is 5-10% longer than the length of the outer peripheral edge of the insole. It has been customary to form a hem and sew the hem and insole while putting a fold in the lower part of the crepe at the toe. However, it requires a high degree of skill and attention to sew with a fold and fold around the undercover where the toe reinforcement of the synthetic leather resin etc. is attached to the toe of the cover. Met.

Therefore, when sewing the insole and the insole having the toe reinforcing piece attached to the toe portion, it is not necessary to draw folds around the insulative bottom so that the lower periphery of the insole and the insole do not have to be gathered. The length of the outer peripheral edge of the cover is substantially the same, that is, the toe part of the cover is compared with a conventional one, and the lower peripheral edge of the cover and the outer peripheral edge of the insole are sewn together on the palm of the hand. It has also been proposed as a cover material. However, when the suspension cover thus constructed is suspended in the shoe mold during the injection molding process of the shoe, as shown in FIG. 6, the seam allowance S between the cover and the insole is formed at the toe portion. However, the tip of the tip of the toe is located at the side of the tip of the toe with the tip of the tip as the apex. The reinforcing tape must be rolled up along the curved curved surface of the toe and above the covering, and since the toe reinforcing tape is extremely thin compared to the sole, the seam allowance part is It is exposed on the surface of the toe reinforcing tape centering on the tip, or the seam allowance part during injection molding blocks the flow of molding material into the toe reinforcing tape forming cavity, and the tape part is partially chipped. However, there was a drawback that the appearance was significantly reduced.

[0004]

[Problems to be Solved by the Invention] The present invention is an injection molding having a toe reinforcement tape which is easy to sew on the cover and the insole and has a good appearance by simply devising the insole. They are trying to provide shoes.

[0005]

[Means for Solving the Problems]

 Referring to the drawings, the present invention forms a lower peripheral edge 11 of a cover 1 having a toe reinforcing piece 13 attached to a toe portion and an outer peripheral edge 21 of an insole 2 in substantially the same length. In a California type caulking material in which the lower peripheral edge 11 of the object 1 and the outer peripheral edge 21 of the insole 2 are seam-sewn 3, the insole 2 is thickly formed on the toe portion toward the longitudinal centerline of the insole. In addition, a crescent or convex lens-shaped notch 4 is used, in which the opposing cutting edges 41 and 41 'are drawn together and sewn together 5, and a draping material for an injection-molded shoe is devised. It is a summary.

In this invention, the insole 4 of the insole is pulled up by the opposing cutting edges 41 and 41 ′ and sewn together 5, so that when the garment material of this invention is hung in a shoe mold, Sewn seam and insole at the tip of the toe 3 The seam allowance is to be pulled down to the bottom or the lower peripheral edge of the last, and is punched into a crescent or convex lens shape. ing. The sewing work 5 of the facing cutting edges 41 and 41 ′ is convenient if it is performed before the sewing of the cover 1 and the insole 2.

[0007]

【Example】

 In the embodiment of the present invention, the cover 1 is constructed by punching and cutting a usual material such as cloth, leather or synthetic resin sheet, and the insole 2 is made of cloth, leather or fiber board. It is configured by punching and cutting a non-woven fabric or the like. When the cover 1 and the insole 2 are cut, the lower peripheral edge 11 and the outer peripheral edge 21 thereof are formed to have substantially the same length. Specifically, the covering 1 is developed and cut according to a conventional method, and the insole 2 is formed by extending a crescent-shaped extension portion (hatched portion) 22 in the toe portion as compared with the conventional one. The outer peripheral edge 21 is designed to match the length of the lower peripheral edge 11 of the cover 1. In the rear of the crescent-shaped extension portion 22, both end edges 411.411 'are substantially adjacent to both end edges 221.221' of the crescent-shaped extension portion 22, and a convex lens-shaped notch 4 is formed. Opposing cutting edges 41 and 41 'of the convex lens-shaped notch 4 are drawn together and sewn together 5, and the extended portion 22 is drawn up to almost the lower edge 222 thereof. The lower peripheral edge 11 and the outer peripheral edge 21 of the insole 2 thus prepared are sewn together by a conventional method to provide a shoe cover material for injection molding.

[0008]

[Effect of the device]

 Since the covering material of the present invention is configured as described above, if it is suspended in the shoe mold 6 in the injection molding process of the shoe, the insole 2 becomes wide in the longitudinal direction along the center line of the insole 2. Since the width is shortened outwardly and inwardly on the left and right sides, the seam allowance portion can be pulled down to the bottom surface or the lower peripheral edge portion of the shoe last 6 by the shortened width. Therefore, it is not necessary to wind up the edge tape on the upper part of the cover by the toe part of the cover as in the conventional case, and the tape part is not chipped or the seam allowance part is not exposed on the tape part. An injection-molded shoe 7 having a good appearance can be obtained.
