[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is to provide a shoe for absorbing the impact of the foot when walking and to provide an insole for absorbing the impact of the foot.

[0002]

[Prior art]

 Recently, the importance of shock absorption of shoes has been recognized, and as for the radial shoes, many shoes in which a composite insole of EVA sponge is inserted. However, in formal shoes, since the style of the shoe is emphasized, it is difficult to insert a thick insole, and the thick outsole or the sponge bottom is used for the outsole. Some shoes have a low-density sponge with a cloth attached on the insole, but it does not have a good impact-absorbing effect, and the adhesive film prevents the insole from absorbing moisture. Just marginalize. In women's pumps, the heels are high and the weight on the feet is large, and countermeasures against this are desired, but until now, no appropriate measures have been taken.

[0003]

[Problems to be solved by the device]

 For shock absorption, it is effective to install a cushion material at the part closest to the sole of the foot, and if the thickness is not less than 2 mm, it is ineffective. Since the current insole is thin and hard, it may cause fatigue of the foot and cause "octopus" and "blister". Improvement of foot contact is required. However, attaching a sponge to the upper and lower surfaces of the insole increases the thickness of the shoe's limbs and destroys the style of a formal shoe. In particular, women's pumps weigh more than 50% on the foot of a thin sole, but it is a difficult problem to deal with as a shoe expressing a fashion on the toes. The role of the insole is to have a good feel on the top and to absorb sweat from the sole of the foot, and on the bottom to adhere and fix the scab that is pulled strongly. Therefore, pasting a sponge or the like on the insole also impairs its function. On the other hand, the bag-type moccasin-made shoe with no insole has a lot of enthusiasts due to its structure, with less pressure on the toes and good return of the sole. However, the lack of a midsole has the drawback that the hard feelings and unevenness on the road affect the soles of the feet through the thin outsole, but it cannot be interrupted by the midsole.

[0004]

[Means for Solving the Problems]

 In the present invention, as the first method of the shock absorbing insole, a cushion material is sandwiched between the insole and the function of the insole currently used is divided into upper and lower. That is, the front half of the insole is split into two pieces, and in the middle, a cushion material that is slightly smaller than the insole and has its periphery removed is sandwiched, and the periphery is glued or stitched. Since the central part of the insole rises to the bottom due to the thickness of the cushioning material, the conventional midsole that filled the step between the scabbard suspending part and the insole should be abolished and the tip of the hanging allowance should be scraped off. , If you scrape off with an adhesive brushed buff, the bottom surface will be horizontal as before. Further, sponge and cork sheets are used as the traction material, but all of them are required to have a quality capable of withstanding the high pressure of insole.

As a second method of shock-absorbing insole, a cushion material, which is slightly smaller than the outer periphery of the insole, is temporarily attached to the upper surface of the front half of the cut thin insole material, Further, a woven or non-woven fabric having high hygroscopicity or natural leather is further covered thereon, and the periphery is adhered or sewn to form a habit.

[0006] For women's shoes such as ladies' shoes with an insole attached to the entire insole, moisture absorption is not taken into consideration, and only the cushion material that has been scraped off is attached on the front half of the existing insole. Stick a backer on the back of the heel and use a quirky insole.

There is also a method of attaching a cushioning material only to the stepped portion where the weight is concentrated on the insole of the women's shoe which has a particularly high heel and requires a delicate toe shape.

[0008] The bag-type moccasin shoe is characterized by softly wrapping the foot in the skin, and a method of blocking unevenness on the ground is to absorb the shock by sandwiching a cushion material that does not prevent the bottom from bending. Let In other words, at the time of smoldering, a sponge or cork sheet, whose periphery has been scraped off, is adhered between the skin and the back skin (including woven or non-woven fabric) of the scabbard at the outsole adhesion position, suspended, and bottomed. On top, sew Mackay. When shoes with a moccasin method are to be bottomed by cement method, a thin pulp board of about 1 mm is cut into a bottoming surface shape, and the cushioning material with the peripheral part slanted off is pasted on it. Insert the bottom into the bottom position of the front and back skins and fix it. When using pulp board, sandwiching the leather skin between the outsole and the board strengthens the bond and eliminates the need for bottom sewing.

[0009]

[Work]

 The suspended insole of the present invention has the same thickness as the conventional insole in the periphery, and there is no biting of the wiper when suspending the skin. Therefore, the thickness of the side surface of the finished shoe does not change, so it is possible to hang it with the conventional size of scabbard, and the style of the shoe is not lost. The cushioning material of the bag type moccasin absorbs the impact on the ground without damaging the return of the bottom. When an open-cell sponge is used as the cushion material or a sponge with numerous small holes is used, not only does it absorb impact, but the air moves due to the compression motion of walking, drying the insole from the back side. At the same time, it also leads to the exhaustion of high-humidity air inside the shoes, which also improves foot stuffiness.

[0010]

【Example】

 As an example of the cushion insole of men's shoes, split the leather part of the middle insole of natural leather with a thickness of 2mm into two pieces, and make a few small holes in the toe part of the upper insole. It was For the cushioning material, a punch mesh-processed urethane sponge with a thickness of 2 mm was used, the circumference was cut 6 mm smaller than the size of the insole, and the periphery was obliquely scraped off and inserted, and the periphery of the insole was adhered and habituated. Adhesive naps for hanging the scabbard were scraped to zero, and the inside was abolished and the bottom was directly sewn and Mackay was sewn.

As another cushion insole processing method for men's shoes, a 25 mm thick urethane having a shape that is 6 mm smaller than the insole on the inside of a 1.5 mm pulp board insole The sponge was partially stopped, pigskin was placed on the sponge, and the surroundings were adhesively sewn, and a cement shoe was finished using the habitual insole.

[0012] The cushioning plate for the stepping part for women is set to cut a 1.5 mm pulp board in a horizontal row in the middle bottom, and cut it into a length of 27 cm and a width of 110 cm, and a sponge only at the position of the stepping part. I stuck it sideways long and thin. As the sponge, an open-cell sponge having a thickness of 25 mm and a width of 7 cm, which was scraped off at the front and back, was used, and a gauze-like cloth was further attached to the entire surface of the board and cut with a midsole type. Both sides of the cross section of the sponge were scraped off diagonally, and a shank-backed backer was attached to the lower surface of the heel to create a quirky insole for a medium-heel pumps finish.

To absorb the impact of the bag-type moccasin shoe, a punch mesh urethane sponge with a thickness of 2 mm is cut into a bottom shape and the peripheral part is slanted off. Adhered to, and made with the back skin. This was suspended and bottomed as usual, and the outsole was sewn with mackey.

[0014]

[Effect of device]

 In the wearing test of the shoe made by the suspension method using the insole of the present invention, even if you step on the pebbles on the concrete, it will be a soft foot contact. Became. Feet of men's shoes have less stuffiness than the conventional insoles, and even when worn for a long time, the surface of the insoles is silky and the dryness is improved. In women's shoes pumps, the feel of the road that hits the foot is soft, and even when walking for a long time, not only the soles of the feet, but also the legs are less tired. The bag-type moccasin shoes have the elasticity of a sponge that wraps around the soles through the back skin, the return of the outsole is the same as the conventional product, and the unevenness on the ground is not felt on the soles. In addition, the mace sewing thread inside the shoe sinks, improving the feel of the foot. Depending on the method of processing the cushion material processed into the insole, there are differences in cost and function, but it is necessary to select from these depending on the purpose of the shoe and the set price.
