Description

  The present invention relates to a waterproof waterproof shoe that is waterproof and also has conductivity so as not to accumulate static electricity in the human body.

  In order to prevent rainwater from infiltrating during walking, waterproof shoes with waterproofing measures on the upper and seams, and shoes with synthetic resin inners on the inner side of the upper are known.

  Also, in dry environments, there are shoes that can discharge the generated static electricity to the ground in order to avoid the shock that is felt when you touch the knob of a room or car due to static electricity generated by friction of clothes etc. Yes.

There are the following two documents regarding shoes having both waterproofness and conductivity.
JP 2003-88404 A JP 2003-93105 A

  The technology disclosed in the above two publications is a useful invention having both waterproofness and conductivity. However, daringly speaking, the structure disclosed therein requires a large number of members and the manufacturing process is complicated. Therefore, the present invention aims to provide an improved shoe for the same purpose by paying attention to this point.

  The invention disclosed in Patent Document 1 is a thread-sewing with a conductive thread over the inner side surface and the outer side surface of the inner bag formed in a foot shape, forming a waterproof treatment layer at the seam to be a conductive part, This is brought into contact with the conductive portion of the shoe sole through the respective conductive portions of the insole and the midsole, and is made conductive.

  In addition, the invention disclosed in Patent Document 2 is a structure in which a waterproof inner formed in a bag-like foot shape is integrated with an upper shell, but the document 1 extends from the inner surface to the outer surface of the waterproof inner. The conductive part is made by threading with conductive thread, while the waterproof inner is sewed with conductive thread and the seam is waterproofed with conductive waterproof film or sheet, and this conductive waterproof film or sheet is used as the conductive part. It is.

  The present invention also includes a waterproof inner formed in the shape of a bag in the shape of a foot on the inside of the shoe, and the conductive part provided on the waterproof inner is connected to the conductive part of the shoe sole via the conductive part of the midsole and the midsole. It is the same in that the two are brought into contact with each other, and the two are made conductive. The main difference is in the method of forming the conductive portion provided on the bottom surface of the waterproof inner and the midsole / midsole.

  According to the present invention, a waterproof shoe having both waterproofness and conductivity can be obtained with the above-described configuration and materials.

  The present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view of a conductive waterproof shoe according to the present invention, FIG. 2 is a longitudinal sectional view of the essential part of the shoe, and FIG. 3 is a plan view of the waterproof inner essential part.

  Generally, it is preferable that the material of the waterproof inner has a certain degree of cushioning and wear resistance, so that a waterproof material such as a polyurethane film is disposed on the outside as described in the above-mentioned known literature, It is preferable that the inside has a structure in which several layers of materials having a certain level of cushioning properties are stacked during walking. For example, a pile fabric such as nylon or tetron, or cold koji is used.

  Even in the present invention, first, a waterproof material such as a polyurethane-based waterproof film is arranged on the outside, and a smooth material that is difficult to get dirty is used on the inside that touches the foot. It shall have a structure in which several layers of fabric materials such as pile fabric and polyurethane foam are stacked so as to have properties. The waterproof inner 1 sews these materials cut into a bottom part, both side parts, etc. into a bag shape, but there is no need to use a conductive thread for the sewing, and the usual use that is generally used A waterproof tape 7 is attached to all the seams.

  The conductive portion 3 provided on the bottom surface of the waterproof inner 1 is formed as follows. First, a window hole 4 having an appropriate shape is provided on the bottom surface of the waterproof inner 1, a rubber sheet piece 5 having the same shape as that of the window hole 4 is applied to the portion, and the peripheral edge of the window is sewn using a normal thread 6 to the window. The inner edge of the hole 4 is sewed, and waterproof tape 7 is attached to the seam.

  The conductive portion 3 provided on the bottom surface of the waterproof inner may be attached by applying a rubber sheet piece having conductivity larger than that of the window hole 4 or may be sewn using a normal thread. . In that case, waterproof tape should be applied to the seams.

  An insole 8 is located below and in contact with the bottom surface of the waterproof inner 1. The insole 8 is commonly referred to as a texon board, and is made of a synthetic material by compression molding or made of a chemical fiber non-woven fabric. A window hole 9 is provided at a position where the conductive portion 3 of the waterproof inner 1 of the inner bottom 8 abuts, and a conductive material is also fitted there to form a conductive portion. In the embodiment, the fabric piece 10 is used in which the fabric is formed by threading the conductive fabric using conductive yarn so that the thickness is substantially the same as the thickness of the insole 8. Instead, a conductive rubber piece is used. May be fitted.

  A midsole 11 is located below the midsole 8. Some ordinary shoes have a structure in which the midsole is formed by integral molding with the outsole so that the bottom surface of the shoe is directly the sole, but in this embodiment, it is separate from the outsole. ing.

  That is, the midsole 11 is made by molding EVA or urethane foam, and has a horizontally long pore 12 that intersects the line connecting the toe and the heel substantially at a position where the conductive portion of the insole 8 comes into contact. Is provided, and a conductive rubber piece 13 is fitted therein to form a conductive portion.

  The reason why the horizontally elongated pore 12 is provided at a position that intersects the line connecting the toe and the heel substantially at right angles is to consider the bending of the shoe sole during walking.

  In addition to the above method, the conductive portion provided in the midsole 11 is provided with a slit at the same position in place of the rubber piece 13 fitted into the pore 12, and a conductive ribbon-like piece of cloth is provided in the slit. You may form by inserting and bending both end pieces.

  A shoe sole 14 having a thickness of several mm is attached below the midsole 11. The shoe sole may be affixed to the entire lower surface of the midsole with an integrally molded product from the heel portion to the toe, or the heel portion and the shoe sole front half portion 15 as separate bodies. In any case, it is assumed that the shoe sole front half 15 has conductivity.

  With the above-described configuration, the conductive portion of the midsole 11 comes into contact with the conductive shoe sole front half portion 15, so that the generated static electricity passes through the conductive portion 3 provided on the waterproof inner 1. Then, the electric conduction is made to the shoe sole 14 sequentially through the conductive portion of the insole and the conductive portion of the midsole.

  As described in (0016) above, when the midsole and the outsole are formed by integral molding, if the front half of the shoe sole that is integrated has conductivity, the insole Since the conductive portion directly contacts the midsole integrated with the shoe sole, the same effect can be obtained.

  Although not mentioned above, in an actually completed shoe, an insole (not shown) is usually laid inside the waterproof inner 1. Therefore, in that case, of course, it is necessary to provide a conductive portion formed by sewing a conductive cloth piece with a conductive thread and sewing it at a portion of the insole that contacts the conductive portion of the waterproof inner. There is.
