[Detailed Description of the Invention] (1) Technical Field The present invention provides a shoe insole that has a heat-insulating effect in winter, does not swell, allows air to circulate around the sole of the foot, and has a good feel. and its manufacturing method.

(2) Background technology A variety of shoe insoles with breathability, odor absorbing properties, etc. have been proposed in the past, such as coarse mesh lining fabric A made of vinylidene chloride synthetic resin monofilament, and insole made of vinylidene chloride synthetic resin monofilament. A shoe insole formed by sequentially stacking the honeycomb intermediate woven fabric B and the resin monofilament fine woven surface woven fabric D and welding the peripheral edges, and the method for manufacturing the same. difference
Place an insulating cushioning material made by laminating a polyester film with a thickness of 0.02 to 0.1 mm on paper with a thickness of 0.1 to 0.5 mm, place the laminated woven fabric on top of that, and then place a layer of woven fabric on top of that, and then place a layer of woven fabric on top of that, and then place a layer of woven fabric on top of that.
0.01 mm polyester films are stacked on top of each other, and the upper electrode, whose inner surface of the protrusion at the lower end is inclined and the outer periphery is sharpened, is lowered toward the lower electrode, and the above cushioning material, laminated woven fabric, and film are placed between the two electrodes. A method of manufacturing an insole by simultaneously welding and cutting the peripheral edges of laminated woven fabrics by crimping and passing high-frequency current between both electrodes is as follows:
It is disclosed in Japanese Patent Publication No. 49-48024.

In addition to the above-mentioned shoe insoles, we have added the two functions of odor absorption and anti-microbial properties by adhering spherical activated carbon to vinylidene chloride-based synthetic resin short fiber nonwoven fabric using latex containing an anti-microbial solution and having open cells. A sheet C is made, and the coarse mesh back woven fabric A, the honeycomb intermediate woven fabric B, and the finely woven surface woven fabric D are combined into the lining fabric A, intermediate woven fabric B, sheet C, and surface woven fabric D. A deodorant and antimicrobial shoe insole made by sequentially overlapping and welding the peripheral edges and a method for manufacturing the same are disclosed in Japanese Patent Application Laid-Open No. 54-22252.

In addition, for the purpose of gradually relieving foot fatigue caused by magnetic lines of force, for example, coarse mesh back woven fabric A made of vinylidene chloride-based synthetic resin monofilament, honeycomb interwoven fabric B made of the resin monofilament, resin and/or chloride A sheet S made of a nonwoven fabric made of short vinyl synthetic resin fibers coated with a mixed latex mixed with activated carbon powder, copper powder, and magnetic powder and then heated, and a finely woven surface fabric D made of the resin monofilament. The insole is made by sequentially overlapping the above and welding the peripheral edges, and the weight ratio of activated carbon powder, copper powder, and magnetic powder to 100 parts of latex is 10 to 50, 10 to 50, and 100 to 400, respectively. , the components of the latex used in the above mixed latex are 100% nitrobutyl latex to 100% nitrobutyl latex, 0.5 to 1.5 sodium lauryl sulfate, 0.5 to 1.5 sulfur,
Shoe insoles containing 0.5 to 1.5 zinc oxide, 0.5 to 1.5 vulcanization accelerator, and 1 to 3 anti-aging agents and their manufacturing method were also published by Tokkosho.
It is disclosed in Publication No. 56-18204.

(3) Purpose The above-mentioned insoles are preferably used in spring, summer, and autumn due to the characteristics of the woven fabrics or sheets that make up each insole, but the insulation and heat retention effect in winter is not necessarily the same. It could not be said to be sufficient.

Therefore, the inventors of the present invention have developed a design that has a thermal insulation effect even in winter, does not swell, allows air to flow through the soles of the feet, has a good feel, and is designed to fit the size of each user's feet. We conducted a study to create a shoe insole with consideration given to adjusting the size of the shoe insole.We used honeycomb woven fabric on the back of the shoe insole, and further layered a top sheet with good texture on the surface to make the periphery. After welding and forming multiple cutting lines,
An extremely good shoe insole was obtained and the present invention was completed.

(4) Structure In other words, the insole of the present invention comprises: fine honeycomb woven fabric B made of vinylidene chloride synthetic resin monofilament, honeycomb intermediate woven fabric B made of vinylidene chloride synthetic resin monofilament, vinylidene chloride synthetic resin and/or or Sheet S, which is a nonwoven fabric made of vinyl chloride-based synthetic resin short fibers coated with a mixed latex mixed with activated carbon powder and/or copper powder and then heat-treated; coarse mesh woven fabric A made of vinylidene chloride-based synthetic resin monofilament; and front sheet. V
This invention relates to an insole for a shoe made by sequentially overlapping and welding the peripheral edges, and by welding a plurality of cutting lines or broken cutting lines corresponding to the size of the foot.

The top sheet V constituting the insole of the present invention is preferably one that has a relatively fluffy feel from the point of view of wearing comfort, and examples thereof include boa, tricot (particularly nylon tricot), velveteen (cor-ten), etc. .

In addition, in the insole of the present invention, two types of honeycomb woven fabrics b and B are present on the back side of the insole, and in particular, the woven fabric b present on the backmost side is the intermediate woven fabric B.
Compared to , the woven fabric should have a finer weave.

(5) Examples Hereinafter, examples of the present invention will be explained with reference to the drawings. A sheet S was prepared by applying a mixed latex mixed with powder and activated carbon powder and then heat-treated, and as shown in FIGS. 1 and 2, the fine honeycomb woven fabric B, the honeycomb intermediate woven fabric B,
This shoe insole is made by stacking a sheet S, the coarse mesh woven fabric A, and a top sheet V in this order, welding the peripheral edges, and welding a plurality of cutting lines L corresponding to each foot size. In addition, in FIG. 1, a indicates a welding part other than the peripheral part (for regulating relative movement of each laminated material).

Next, an example of the method for manufacturing the shoe insole of the present invention will be explained with reference to FIG. The fine honeycomb woven fabric B, the honeycomb intermediate woven fabric B, the sheet S obtained by coating and treating the mixed latex on the nonwoven fabric, the coarse mesh woven fabric A, the top sheet V, the woven fabric b, the intermediate woven fabric B, A laminate L in which the sheet S, the woven fabric A, and the top sheet V are stacked in this order is intermittently pulled out along the upper surface of the flat lower electrode 3 via a roller 10 by a tensioning device (not shown), and the laminate L and the flat plate Between the lower electrode 3 and the
An insulating cushioning material 4 made of paper with a thickness of 0.1 to 0.5 mm laminated with a polyester film of 0.02 to 0.1 mm in thickness is applied to the upper surface of the laminate L via rollers 11 and 12, and a thick layer is applied to the upper surface of the laminate L via rollers 13 and 14. Layer polyester films 6 with a thickness of 0.01 to 0.02 mm, move these three intermittently at the same speed, lower the upper electrode 7 shaped like the outer periphery of the shoe insole toward the lower electrode 3, and remove the upper cushioning material 4. , the laminated woven fabric 5 and polyester film 6 are crimped between both electrodes, and a high frequency current is passed between the electrodes 3 and 7 to weld the periphery of the laminate. A cutting line or a broken cutting line is formed by welding, and then punched out.

FIG. 4A shows a bottom view of the upper electrode, and FIG. 4B shows a sectional view taken along the line -- in FIG.

The upper electrode 7 has an electrode 7' shaped like the outer periphery of a shoe insole, and an electrode 7'' for welding a plurality of cutting lines or broken cutting lines corresponding to the size of the foot.
The fourth electrode 7' has the shape of the outer periphery of the shoe insole.
As shown in Figure B, it has a shape with an inclined inner surface and a sharpened outer circumference.

Therefore, welding and cutting of the peripheral edge of the laminate are performed by the electrode 7', and welding of a plurality of cutting lines or broken cutting lines corresponding to the size of the foot is performed by the electrode 7''.

(6) Effects The shoe insole of the present invention has the above-described laminated structure and can exhibit the following excellent effects due to the characteristics of each laminated material.
In other words, since the sheet S and the front sheet exist,
It can provide heat insulation properties, and when worn, the sole of the foot is less susceptible to temperature changes directly under the shoe, thus contributing to improved comfort.

B. Intermediate woven fabric B and further woven fabric b are laminated on the back side of sheet S, and woven fabric A is placed on the back side of front sheet V, so that the heat shielded by each sheet S and V can be transferred to each woven fabric B, It can be released through b and A, so the sole of the foot does not get stuffy.

C. Woven fabrics b and B present on the back side are both thickly woven into a honeycomb shape, so they have a cushioning effect, but in particular, woven fabric b present on the back side is compared to intermediate woven fabric B. The insole has a fine weave, giving it durability. In other words, when the insole is inserted into and taken out of the shoe, or when the insole is worn, the innermost surface of the insole "rubs" against the shoe, especially the upper surface of the insole, and this also causes the woven fabric b to Does not wear out easily.

(d) The presence of vinylidene chloride-based woven fabrics, especially woven fabrics A and B, provides excellent elasticity and contributes to improved comfort.

Since the sheet contains activated carbon, it can absorb the bad odor generated inside the shoes, and since it contains copper powder, it can prevent the occurrence of athlete's foot.

F. Since the top sheet is placed in a position that directly contacts the sole of the foot, that is, on the outermost side, it provides good feel on the sole of the foot, thus contributing to improved comfort.

G. Since multiple cutting lines or broken cutting lines are formed,
The size of the insole can be changed using the cutting line depending on the shoe in which the insole is used, and therefore, the insole has wide versatility.

In addition, in this method of manufacturing shoe insoles, it is impossible to manufacture them by welding and cutting in one operation due to the presence of the top sheet, but since welding can be done using high frequency, it can be made more efficient by performing the punching separately. It can be manufactured.

As described above, the shoe insole of the present invention has an insulating effect even in winter, does not get stuffy due to air circulation in the sole of the foot, has a good feel, and has an insole during use. It is especially excellent in that it takes care to adjust the size of the bed.
