Description

  The present invention relates to a shoe insole that can improve exercise performance by adjusting the amount of friction generated between a sole and an insole during exercise and increasing the grip force in the vertical direction and the horizontal direction.

  Traditionally, shoe insoles have functions such as breathability, antibacterial, deodorant, shock absorption, comfortable fit, arch support, flex, rebound, among others, breathability, antibacterial, deodorant, shock absorption Such functions are emphasized.

  In addition, as shown below, a shoe sole, a midsole attached to a shoe, and a cup insole have been proposed in which a groove is formed on the surface structure.

  Japanese Patent Application Laid-Open No. 2002-282010 discloses that the toe part has a sufficient flexibility even when a relatively hard material is used for the insole material, and it is easy to walk. An arbitrary number of horizontally long through grooves are provided substantially parallel to a line connecting a portion corresponding to the thumb base portion and a portion corresponding to the little finger root portion, and the groove width of the through groove is set to 100 to 50% of the thickness of the insole material. An insole material for shoes is disclosed (Patent Document 1).

  Japanese Patent Application Laid-Open No. 07-289309 has a purpose of obtaining an insole of a footwear made of a natural material made of wood and having a depth slightly shorter than the thickness of the wood layer on the surface of the wood. An insole for footwear is disclosed in which a plurality of V-shaped grooves are formed at predetermined pitches in the vertical and horizontal directions (Patent Document 2).

  In addition, utility model registration No. 3071186 discloses a plurality of ventilation grooves provided on the upper surface, an air chamber communicating with the ventilation grooves in the heel, and ventilation grooves for the purpose of manufacturing shoes with good ventilation. There is disclosed a shoe sole that includes a vent hole that communicates with the air vent and opens on the outer side surface, and a check valve type air valve that suppresses ventilation from the outside to the inside provided in the vent hole (Patent Document 3). ).

  In addition, the utility model registration No. 3002407 discloses a shoe insole that is superior in preventing foot spilling and deodorizing effects, and has a number of longitudinal grooves on the upper surface of the insole body from the toes toward the heel. A shoe insole in which a plurality of lateral grooves are communicated with the longitudinal groove is disclosed (Patent Document 4).

  In addition, Japanese Utility Model Publication No. 08-778 discloses a shoe insole that is easy to walk and exercise smoothly even when worn for a long time. In addition, a groove that communicates with each other is formed in the lower surface of the portion where a gap is likely to be generated between the sole and the insole when not stepped on, and a plurality of holes are formed on the groove almost vertically. And a shoe insole that is tapered from between the toes and the ball portion is disclosed (Patent Document 5).

  In addition, Japanese Utility Model Laid-Open No. 04-36803 discloses that it is possible to prevent the occurrence of sagging and deformation in the portion from the buttocks to the front of the stepping portion even with an uneven load, and to bend appropriately during walking. For the purpose of fully exhibiting the performance and resilience, as the reinforcing plate, the rear reinforcing plate extending from the substantially front end position of the heel portion of the shoe sole body to the vicinity of the stepping portion and the rear reinforcing plate are arranged separately. A shoe sole including a front reinforcing plate extending from the tip end side of the finger base to the toe side is disclosed (Patent Document 6).

In this case, since the lateral concavo-convex groove 21 and the vertical concavo-convex grooves 23 and 24 are formed integrally with the main body of the 25 shoe insole 20, a firm concavo-convex groove can be formed on the surface of the main body.

  When the shoe insole 20 having the above-described configuration is inserted into the inner bottom of the shoe and used, the lateral concave and convex grooves 21 grip the toes during straight vertical movement to increase the straight driving force. The vertical concave and convex grooves 23, 24, and 25 can grip and stretch the rear part of the toes (the thumb ball part and the little finger ball part) during lateral movement, enabling quick and well-balanced movement. Become.

  FIG. 3 is an explanatory view showing a third embodiment of a shoe insole according to the present invention.

  As shown in FIG. 3, the region corresponding to the toe portion on the surface of the main body where the sole of the insole 20 hits the foot (in the region of the toe portion from the line 22) is continuous in both vertical and horizontal directions across both sides of the insole 20. A plurality of grid-like projections 30 are formed. In addition, the area corresponding to the thumb ball part and the little finger ball part on the surface of the main body where the sole of the shoe insole 20 hits, and the area between the little ball part and the front of the buttocks (in the area behind the toe part from the line 22) A plurality of continuous undulating grooves 23, 24, and 25 having a continuous corrugated shape arranged in the longitudinal direction across both sides of the shoe insole 20 are formed. The line 22 indicating the boundary between the toe portion and the back of the toe portion is not limited to the shape shown in the present embodiment, and the lattice-shaped protrusion 30 and the vertical uneven grooves 23, 24, and 25 are separated. Thus, a shape that can be formed can be employed as appropriate.

  The insole 20 is characterized in that a lattice-like protrusion 30 and vertical concave and convex grooves 23, 24, and 25 are formed in order to increase both the vertical and horizontal gripping force of the toe portion and the lateral gripping force behind the toe portion. It becomes. The grid-like projections 30 are set in a range of 0.5 mm to 4 mm in height, and the concave and convex grooves 23, 24 and 25 are set in a range of depths of 0.5 mm to 4 mm and widths of 1 mm to 5 mm. The effect of can be produced. These concave and convex grooves are formed in a continuous corrugated shape in order to increase the amount of friction generated between the sole and the insole, as in the second embodiment described above, to increase the gripping force. ing.

  As a method for manufacturing the shoe insole 20, a method is employed in which a foamed polyurethane material is used and molded by hot pressing at a high temperature, as in the first embodiment.
