[0030] The following will be combined with the attached embodiment of the present invention Figure 1-15 , the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] In these figures, reference numeral 1 will denote an insole according to this embodiment.

[0032] Example 1 Reference Figure 1-15 The invention discloses an insole, which is arranged on the upper part of the sole and comprises a base body for placing the foot. A cooling part is formed in the base body by mixing a coolant.

[0033] An insole having such a construction is used by being placed on the upper surface of the sole on the inner side of a shoe, but when the shoe is worn, the sole of the foot will conform to the insole as previously described.

[0034] A shoe insole, at the same time, because the cooling sensor mixed in the shoe insole plays a role, the temperature rise inside the shoe is suppressed, and the sole of the foot directly or indirectly contacts the cooling part to obtain a cool feeling, so that the steam feeling caused by the heat inside the shoe is reduced.

[0035] In an insole, the cooling part can be arranged on the entire base, or can be arranged separately at a position corresponding to a specific part of the sole of the foot, such as the base of the foot or the heel.

[0036] A shoe insole, furthermore, by forming a base body with an adhesive material, when the shoe insole is attached to a shoe lining, the shoe insole can be closely fitted to the upper surface of the sole, thereby suppressing the problem of deviation from the sole.

[0037] In addition, the insole can reduce the impact when walking by giving the aforementioned base body elasticity, and can also play a synergistic role by reducing the discomfort caused by the aforementioned heat and inhibiting the displacement of the insole, thereby greatly improving the comfort of wearing shoes.

[0038] The utility model relates to an insole, wherein a mesh sheet can be adhered to the upper surface of the base body, that is, the surface on which the foot is placed.

[0039] A shoe insole has such a structure that a plurality of gaps are arranged between the aforementioned base and the bottom side of the mesh sheet, thereby improving the air permeability therebetween.

[0040] The insole can improve the wearing feeling of the shoe by suppressing the displacement of the foot relative to the base body caused by the aforementioned mesh sheet, thereby improving the comfort.

[0041] A shoe insole, in which the mesh sheet is provided, openings are formed at the portion corresponding to the heel, the portion corresponding to the metatarsal bone, and the portion corresponding to the root of the toe, and the cooling portion is also located in these openings.

[0042] In an insole, a part of the base can directly contact a specific part of the sole of the foot by using such a structure, thereby maintaining the function of the mesh sheet and the cooling effect of the coolant can directly act on the foot.

[0043] A shoe insole, at the same time, the cooling component can be integrally provided on the mesh sheet and connected to the base together with the mesh sheet.

[0044] The invention discloses an insole which uses menthol as the cooling agent and can form the cooling part by dissolving the cooling agent in a gel-like polyurethane resin.

[0045] Example 2 Reference Figure 1-15 , a shoe having an insole, like a shoe into which the insole is inserted, the instep is set at the upper part of the sole and a cavity is formed, into which the foot is inserted so as to effectively extract its function, and a through hole extending from the upper surface to the lower surface is formed at a position corresponding to the sole part where the cooling part of the insole is set.

[0046] A shoe with an insole has such a structure that external air contacts the insole through the through hole, a cooling part arranged on the insole can be cooled by the external air, and cold air mixed into the cooling part can suppress the reduction of the cooling effect of the cooling agent.

[0047] A shoe with an insole is preferably provided with a foreign body intrusion prevention component with air permeability, and can prevent foreign bodies from entering between the soles through the soles.

[0048] A shoe with an insole, wherein the foreign body intrusion prevention component is fixed by a fixing sheet adhered to the upper surface of the sole. The fixing sheet is formed with an opening at a portion overlapping with a through hole formed in the sole to ensure heat exchange between the outside air and the insole. In addition, by providing the fixing sheet, the adhesion between the upper surface of the sole and the insole can be improved, and the deviation of the insole can be effectively prevented.

[0049] Example 3 Reference Figure 8-9 , an insole, the insole 1 of this embodiment has a base 2 formed of a viscous elastic material, and by mixing a cooling induction agent in the base 2, the base 2 as a whole becomes a cooling part.

[0050] In this embodiment, the base 2 is made of gelled polyurethane resin, which has peelable adhesiveness and elasticity for daily use of shoes.

[0051] Furthermore, for example, menthol is used as the aforementioned coolant, and the menthol is dissolved in the aforementioned base 2 and mixed.

[0052] Furthermore, the mesh sheet 3 is also pasted on the upper surface of the aforementioned base 2.

[0053] The mesh sheet 3 has openings 3a, 3b, 3c at each of the middle portions corresponding to the heel portion, the portion corresponding to the metatarsal bone of the foot, and the portion corresponding to the base of the toes.

[0054] The mesh sheet 3 is made of a material selected from antibacterial and deodorizing fibers and has antibacterial and deodorizing functions. Due to the good air permeability of a large number of ventilation holes, it has the function of dissipating sweat and heat.

[0055] like Fig. 9 As shown, in the state where the aforementioned mesh sheet 3 is adhered to the base 2, the mesh sheet 3 passes through the openings 3a, 3b, 3c formed in the mesh sheet 3 to form protrusions 2a, 2b and 2c protruding from the upper surface, and the protrusion 2a formed corresponding to the heel has a plurality of protrusions 2d.

[0056] When the foot is placed on the insole 1, the protrusions 2a, 2b, 2c will be better fused and deformed, so that the base 2 is adapted to the heel, metatarsal bones and bases of fingers, so that the insole 1 fits the foot firmly.

[0057] Example 4 Reference Figure 1-7 , a shoe equipped with the insole as described in the above embodiment is described.

[0058] In these figures, the shoe indicated by reference numeral 10 is composed of a sole 11 and an instep 12 which is arranged on the upper portion of the sole 11 and forms a cavity A into which the foot is inserted, and the aforementioned sole 11 is formed with a through hole 11a extending from the upper surface to the lower surface, and the aforementioned insole 1 is in close contact with the upper surface of the sole 11 by its adhesiveness, thereby covering the through hole 11a.

[0059] In the present embodiment, the base portion 2 is made of a gel-like polyurethane resin, and the through hole 11 a is sealed watertightly.

[0060] Furthermore, if Figure 3 and Figure 4 As shown, a recess 11b is formed on the upper surface of the aforementioned sole 11 to include the portion forming the aforementioned through hole 11a. In the recess 11b, a foreign matter intrusion prevention component 13 is installed that covers the through hole 11a from the inner surface side of the shoe 10 and has air permeability and can prevent foreign matter from passing through.

[0061] like Figure 5 As shown, the foreign body intrusion prevention component 13 is composed of a substrate 13a formed with a plurality of slits S and an upper plate 13b formed with micro holes as a whole, and the upper plate 13b is mounted on the substrate (see Figure 6 ).

[0062] like Figure 3 As shown, the aforementioned foreign matter intrusion prevention component 13 is fixed to the upper surface of the sole 11 and covered by the fixing sheet 14 .

[0063] An opening 14a is formed on the fixing plate 14 at a position overlapping with the through hole 11a formed in the sole 11, and the inside and outside of the sole 11 are connected to each other through the through hole 11a.

[0064] Next, while describing the function of the shoe 10, the function of the aforementioned insole 1 will also be explained.

[0065] The foreign body intrusion prevention component 13 is fixed in the shoe 10 by the fixing plate 14 , and is inserted into the insole together, and is also tightly installed with the fixing plate 14 .

[0066] Thus, in the shoe 10 equipped with the insole 1, a portion of the lower surface of the insole 1 is covered by the opening 14a of the fixing plate 14, the gap of the foreign matter intrusion prevention component 13, and the through hole 11a of the inner wall 11a of the sole 11.

[0067] When the aforementioned shoe 10 is worn on the foot, the sole of the foot is pressed against the upper surface of the insole 1 according to the weight of the wearer.

[0068] Here, the protrusions 2a, 2b, 2c provided on the base 2 of the insole 1 at the respective parts of the heel, the metatarsal part of the foot and the base of the fingers can withstand the deformation after being crushed.

[0069] According to this, each of the protruding portions 2a, 2b, 2c is brought into contact with each of the heel, metatarsal portion and base of the fingers so that these portions can be firmly held.

[0070] Furthermore, the aforementioned sole of the foot is pressed against the mesh sheet 3 provided on the upper surface of the base 2, thereby preventing the foot from being misplaced.

[0071] According to this, a sense of unity can be obtained between the foot and the shoe 10, and a good sense of comfort can be achieved.

[0072] Furthermore, a coolant is mixed into the base 2 of the shoe 1 that is pressed by the foot, so that the cooling effect of the coolant acts on the sole of the foot, and the discomfort such as steam can be alleviated.

[0073] From this point of view, the comfort of the shoe 10 can be improved.

[0074] Furthermore, since the mesh sheet 3 forms a large number of gaps on the sole of the foot, ventilation can be achieved on the sole of the foot and the temperature rise around the sole of the shoe can be suppressed.

[0075] Furthermore, the outside air constantly contacts the lower surface of the insole 1 through the through hole 11 a of the sole 11 and the gap between the foreign matter intrusion prevention member 13 .

[0076] The insole 1 and the coolant mixed in the insole 1 are continuously cooled by the outside air, thereby maintaining the cooling effect of the coolant.

[0077] As a result, the above-mentioned good comfort performance is continuously maintained.

[0078] Here, one foot is wearing a shoe to which a common insole of EVA resin (ethylene vinyl acetate copolymer) without a cooling compound is attached. The other foot is wearing the insole 1 of the present invention and Fig.10 To represent the temperature change inside the shoes after walking for 1 hour.

[0079] exist Fig.10 In FIG. 1 , curve X represents the change in the internal temperature of a shoe wearing the insole 1 of the present embodiment, and curve Y represents the change in the internal temperature of a shoe wearing a common insole.

[0080] The temperature at the elapsed time "0" represents the internal temperature before the shoe is worn.

[0081] Like this, the internal temperature of the shoe with the general insole rises to above 35° C. immediately after the start of walking, and then gradually rises to the maximum temperature point of 37.4° C. The internal temperature of the shoe 10 to which the insole 2 of the present embodiment is attached gradually rises from the start of walking and its maximum temperature is suppressed to 35.1° C. The effect is clear.

[0082] On the other hand, in the present embodiment, since the through hole 11 a is closed in a watertight state by the insole 1 on the inner surface side of the shoe 10 , water does not enter the shoe 10 .

[0083] Even if foreign matter enters the through-hole 11 a , it is possible to prevent the foreign matter from entering the shoe 10 through the foreign matter intrusion prevention member 13 .

[0084] It should be noted that the shapes, compositions, dimensions, etc. of the components described in the above embodiments are merely examples and can be modified in various ways according to design requirements, etc.

[0085] For example, in the above-mentioned embodiment, an example is shown in which the base material 2 is formed of a gel-like polyurethane resin, but it is apparent that a conventional gel material may also be used.

[0086] Furthermore, the base 2 may be formed of a variety of elastic materials.

[0087] In addition, for example, a large number of fine pores are formed in the base 2. This is also a structure having air permeability.

[0088] By adopting such a structure, the cooling effect can be further improved by mixing the coolant into the base body 2 so that it can have good contact with the external air.

[0089] In addition, you can use Figures 11 to 15 The insole 20 is shown.

[0090] like Fig.15 As shown, the insole 20 includes a base 21 , a mesh sheet 22 bonded to the upper surface of the base 21 , and a cooling portion 23 disposed on the mesh seat 22 .

[0091] On the base 21, as Fig.15 As shown, openings 21a and 21b are formed at a portion corresponding to the heel and a portion corresponding to the base of the toes of the foot, respectively.

[0092] On the other hand, when the grid sheet 22 is attached to the upper surface of the base 21 , the cooling portion 23 provided on the grid sheet 22 is arranged at a position covering the openings 21 a and 21 b formed in the base 21 .

[0093] According to the insole 20 of the present embodiment constructed as described above, each cooling portion 23 is inserted into the through hole 11 a and the openings 21 a , 21 b formed in the base 21 in a state in which the upper surface of the sole 11 of the insole 20 is grounded.

[0094] As a result, a temperature rise in the cooling unit 23 can be suppressed, thereby ensuring a cooling effect.

[0095] In addition, since the cooling portion 23 corresponds to the base of the toes and the heel, a cooling feeling can be applied to the foot that may be heated.

[0096] It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is limited by the appended claims rather than the above description, and it is intended that all changes within the meaning and scope of the equivalent elements of the claims are included in the present invention.
