Problems solved by technology

When the top has two inserting shafts, three insert moldings are required, and when there are three inserting shafts, four insert moldings are required, and the manufacturing process is complicated.
[0009] In addition, Japanese Patent Application Laid-Open No. 2005-304978 describes that, in view of the excellent affinity between soft urethane resin and hard urethane resin, hard urethane resin is made of hard urethane resin by insert molding. The insert shaft part made of ester resin and the top body part made of soft urethane resin are bonded to each other, but when the parts are small like the top part of women's high-heeled shoes, there is a problem that it cannot secure enough due to the small contact surface. The condition of the cohesive force

Embodiment 1

[0066] An intermediate member made of soft urethane resin containing 20% ​​by weight of glass fiber is mounted on a mounting pin having a base portion with a diameter of 6 mm and a shaft portion with a diameter of 3.00 mm and a length of 13.0 mm protruding from the center of the shaft portion. (Hardness JIS A 90A) is a ring shape with a diameter of 9.0mm, an inner diameter of 2.985mm, and a thickness of 1.5mm. A square part with a width of 17.0mm x a length of 14.0mm x a height of 5.0mm is used as the main body of the sky and is inserted into the center. And the installation pin and the middle part are fixed. In addition, soft urethane resin (hardness JIS A 90A) is used for the main body of the sky skin.

[0067] Use three such sky skins, clamp the embedded shaft of the sky skin in the mold, clamp the sky skin body with a tester (dial type torque wrench, trade name "TONE / T3DN15"), rotate at 20mm per minute, and evaluate at the same time strength. The intensity at this time i...

Abstract

The invention provides nature skin manufactured easily with superior fixity of mounting pin. The mounting pin constituted by basis and axial region set on the basis makes the axial region eminently fix on the body of the nature skin, wherein an intermediate element with penetrating hole is set on the axial region, and the intermediate element and the said basis are both fixed on the body of the nature skin.

Description

technical field [0001] The present invention relates to a toplift (toplift) mounted on the bottom of the heel of a shoe and a shoe with the toplift mounted on the heel. Background technique [0002] A top made of hard rubber or the like is attached to the end of the heel of women's shoes or the like. Such a top is used to protect the heel, which is prone to wear, when it directly contacts the ground by being installed on the bottom surface of the heel of a shoe. In order to prevent damage to the heel abutment, when the top is worn, it is properly replaced with a new one. [0003] Generally, the joining of the heel abutment and the main body of the top can be performed by nailing, joining with an adhesive, or pressing the top with synthetic resin protrusions. In addition, as shown in FIG. 7 , in the heel base ( 11 ) that is drilled with a vertical hole ( 13 ) and inserted into the metal pipe ( 15 ), an insert-molded heel is fitted and installed in the vertical hole ( 13 ). ...
