【考案の詳細な説明】
この考案は、射出成形靴に関するものであって、その目
的とするところは軽量で、靴底と中底との接着強度なら
びに胛被と靴底との接着強度に優れたものを提供しよう
とするものである。[Detailed description of the invention] This invention relates to injection molded shoes, and its purpose is to be lightweight and to have excellent adhesive strength between the sole and the midsole, as well as between the shoe cover and the sole. The aim is to provide the following.
従来、ラステンダストリング方式の胛被に、即ち胛被の
下周縁に、その全周にわたって、縫糸でかがり縫を施し

靴底に中底を接着した射出成形靴は公知である。Conventionally, in the rusten dust string method, overlock stitching is applied to the lower periphery of the string over the entire circumference of the string to form a large number of loops, and the string string is inserted through the loops. Injection-molded shoes are known in which a shoe sole is injection molded onto a shoelace that is tightened so that the shoelace is suspended from a shoe last, and an insole is bonded to the shoe sole.

に比較して、胛被の縫製作業が簡単で、しかも靴型に対
する型態み（密着性）が良好であるために、種々の射出
成形靴の製造に採用されている。Injection-molded shoes using this last-string-type shoe cover are easier to sew the shoe cover than injection-molded shoes that use the conventional bag-stitched shoe cover, and the shape of the shoe mold is much smaller. Because of its good adhesion, it is used in the manufacture of various injection molded shoes.

As shown in No. 55 or Fig. 5, the sole and the insole are bonded at the outer periphery of the shoe through the hanging part of the shoe cover, and the hanging part of the shoe cover is Since the unevenness is formed by the large number of loops and the string strings inserted therein, the adhesive strength between the sole and the midsole through the hanging part of the shoe cover is significantly reduced.
特に、この種の射出成形靴において、靴底の踵部には、

Multiple cavities are formed to reduce weight, and these cavities reduce the adhesive area with the insole, and the heel area is free from the bulge formed in the hanging part of the heel. The pleats, combined with the aforementioned loops and strings,
Since the unevenness formed in the hanging part of the shoe cover is made more complex, the adhesive strength between the sole and the midsole through the hanging part of the shoe cover is more significantly reduced. It had become.
この考案は、これらの欠点を除去したものであって、以

特徴とする射出成形靴を要旨とするものである。This invention eliminates these drawbacks, and will be described below with reference to the drawings. In the heel part of a shoe in which the sole 2 is injection molded on the lace 1 of the rusted dust ring type, laces are formed on the periphery of the heel. When the loop a and the string are tied above the hanging part 11 of the cover, it extends to cover the folds C, and also connects the sole 2 and the anchor through the hole 111 made in the hanging part 11 of the cover. The insole 4 is attached to a plurality of sole reinforcing beams 3゜3..., which are provided with integrated extension portions 31, 31... and integrally protrude from the sole 2. The gist of the invention is an injection molded shoe characterized by adhesive bonding.
この考案において、胛被１は、布、皮革、合成樹脂シー
ト、またはそれらを貼合せたもの等の公知なもので形成
