Abstract

<P>PROBLEM TO BE SOLVED: To provide an insole of a shoe capable of securely maintaining a deodorization effect by dravite powders not flaking away. <P>SOLUTION: Innumerable projections 3 consisting of the dravite fine powders of powdery agglomerate consisting of a cementing material and a blowing agent are disposed in parallel on the whole area of a surface sheet 2 made of a cloth covering and adhering to an upper face 1a of an insole base 1. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a bottom material of a shoe such as an insole that constitutes an upper surface layer of the shoe sole.

  So-called drabite (a kind of tourmaline) is known to have various effects such as far-infrared rays, deodorization, deodorization, antibacterial activity, and promotion of plant growth. Focusing on the deodorizing effect, it is used as a component for insoles of shoes.

  As an application of tourmaline to an insole for shoes, there is a structure in which a cotton-like layer is provided on an insole substrate and tourmaline fine particles and powder are contained in the cotton-like layer (for example, Patent Document 1). .

Japanese Patent Laid-Open No. 2001-70008

  The conventional example uses the cushioning property in the thickness direction of the flocculent layer to allow air to flow in and out of the flocculent layer (when walking) and to contact the tourmaline contained in the flocculent layer, and to achieve the desired effect. As expected, since tourmaline particles and powder are in a free state with respect to the fibers constituting the cotton-like layer, the particles fall off from the cotton-like layer (insole), and as time passes This effect is reduced, and because the insole itself has a cotton-like layer, moisture is prevailed. From this point, it is a problem whether the expected effect can be expected. Since it cannot be expected to return to the state, there are various restrictions in use such as avoiding rain.

  Innumerable protrusions made of fine powder of drabite, which are made up of particles of a bonding agent and a foaming agent, are arranged in parallel across the entire surface sheet made of cloth that is bonded to the upper surface of the bottom substrate. It is made a configuration.

  According to the present invention, since the drabite powder is arranged in a state of being fixed to the substrate, the drabbit powder is prevented from falling off, and therefore, the bottom material such as an insole using the drabite that prevents the reduction of the function due to the dropping is prevented. Can provide.

  In addition, since the sole is placed on the sole through a protrusion including drabbit, a slight gap is created between the sole and the sole, air is circulated, preventing moisture retention and moisture. Can prevent various harmful effects.

  The drawings show an embodiment in which the bottom material of a shoe such as an insole according to the present invention is applied to the insole. FIG. 1 is a plan view, FIG. 2 is a cross-sectional view of FIG. 1, and FIG. is there.

  The insole A according to the present invention is an EVA resin (which may be polyurethane or rubber) that has a contour shape approximate to the contour shape of a shoe sole, and is placed in the shoe and overlapped on the shoe sole (insole). The upper surface 1a of the insole substrate 1 is formed by overlaying a cloth surface sheet 2 and bonding the back surface thereof with an adhesive 4 to cover the upper surface 1a.

  The top sheet 2 is made of a fiber body made of polyester fiber (may be nylon fiber), and the countless protrusions 3,..., Made of a mixture of a bonding material and a foam material, mixed with fine powder of drabite ceramics on its surface. By using a fabric sheet 2 having a small weave diameter as a woven fabric, 4 layers of adhesive, 2 layers of surface sheets and 3 layers of protrusions are layered on the upper surface of the insole substrate 1. The uppermost protrusions 3 are formed on the surface sheet 2 layers.

  In order to obtain the insole A of the example, on the adhesive applied to the upper surface of the insole substrate 1 (injection-molded), a mixture consisting of a bonding agent, a foaming agent and fine powder of Drabite was printed on the upper surface by printing means. When the cloth surface sheet 2 is overlaid and heated, and the cloth surface sheet 2 is pressed against the substrate 1 while heating, the mixture swells with a foaming agent to form protrusions 3,..., And the insole A can be obtained. .

  In the embodiment, the present invention is applied to the insole. However, the present invention may be used for a so-called insole. In this case, the illustrated insole substrate 1 is integrated with the bottom material. Configure the substrate.
