Problems solved by technology

This top is proposed in view of the following two problems in the heel protection decoration described in the above-mentioned Patent Document 1: Since the hard urethane layer is formed, the hard urethane layer becomes thick, and the soft urethane layer becomes thicker. Thinning of the urethane layer (problem 1); as its manufacturing method, since the hard urethane resin is mold-cast on the substrate part of the metal part, the hard urethane resin and the soft urethane Ester resin performs two-color molding and integrates the three, so molding is troublesome (problem 2)

Embodiment 1

[0087] This test piece was mounted on a tensile testing machine, and the average peeling force was calculated|required. In addition, on a tensile tester, the end of the hard synthetic resin layer of the test piece was fixed, pulled up with the soft synthetic resin layer interposed therebetween, and the peeling force was evaluated as the strength until peeling. Table 1 shows the results.

Embodiment 2

A mounting pin having a base with a diameter of 7.5 mm and a thickness of 0.8 mm and a shaft portion with a diameter of 3.05 mm and a length of 13.5 mm protruding from the center of the base is placed in a chamber with an inner cavity of 11.1 mm in width x 11.3 mm in length x 7.0 mm in depth The horseshoe-shaped main body of the sky, such as Figure 17 As shown in (b) and (c), a through portion 4a with a diameter of 1.9mm and a depth of 5.0mm can be formed at three positions, and non-through portions are formed between the above-mentioned through portions 4a and at four positions at the center and lower part of the mounting pin. In the mold for injection molding of the concavo-convex portion 4b, a polyurethane elastomer (manufactured by BASF, trade name "ET164D"; hardness 64D) was heated to a temperature of 200 to 210°C, filled and cooled to fix it. The obtained intermediate was inserted into a mold for injection molding of the skin, and a polyurethane elastomer (manufactured b...

Abstract

A toplift comprising a toplift main body composed of two layers consisting of a soft synthetic resin layer ¢I! and a hard synthetic resin layer and, projecting from the toplift main body, a mounting pin. The ground contact surface of the toplift consists of the soft synthetic resin layer ¢I!, and the soft synthetic resin layer ¢I! and the hard synthetic resin layer are joined together by fitting together of projecting and indented portions. As the ground contact surface consists of the soft synthetic resin layer ¢I!, slipping in walking can be prevented. As the junction is made by fitting together, the durability of the toplift main body is excellent.

Description

technical field [0001] The present invention relates to a soft top mounted on the bottom of the heel of a shoe, a shoe with the top mounted on the heel, and a method for manufacturing the top. Background technique [0002] There are shoes in which the skypipe is installed only on the ground contact surface of the heel of the sole. The sky skin, because it is installed on the bottom surface of the heel of the shoe, is directly grounded and protects the heel that is easy to wear. If the sky skin is worn, it should be replaced with a new sky skin to prevent damage to the heel matrix. In addition to the mechanical strength suitable for the protection of the heel base, such a top is required to have the function of eliminating the sound during walking and preventing slippage even when walking on a smooth road surface. [0003] As such a top, a flat base and a shaft portion of a mounting pin protruding from the base protrude, and the base is embedded with a synthetic resin, and h...
