Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an insole that constitutes the bottom of a shoe.

[0002]

[Prior art]

 The insole of the shoe is used to sandwich and secure the instep between the shoe sole and the sole of the shoe, and since it directly touches the sole of the wearer, it must be durable enough to be used for a long time. On the other hand, when walking or running, a certain degree of flexibility is required in the front half of the toe of each toe so as to follow the movement of the wearer's foot.

Therefore, as shown in FIGS. 3 and 4, the base plate 1 is made of compressed pulp having excellent rigidity and hygroscopicity, and a hollow portion 7 is provided in the front half of the base plate 1. A generally known insole is a hollow portion 7 in which a flexible material 8 such as a sponge is embedded.

[0004]

[Problems to be solved by the device]

 However, the insole in which the soft material is embedded has the problems of poor durability and poor wearing comfort, and the number of manufacturing steps and time required for manufacturing, which leads to increased cost of the product. It was

Therefore, an object of the present invention is to provide a shoe insole which does not impair durability and wearing comfort and has sufficient flexibility to follow the movement of the foot.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, in the insole according to the present invention, a large number of through holes are provided in a mesh shape in the front half of the base plate.

In a shoe using such an insole, since the front half of the base plate is easily bent due to the mesh-like through holes, appropriate flexibility is imparted even if the base plate has high rigidity. The durability is not impaired. In addition, since it is not necessary to provide a hollow portion or a flexible material, it does not take time and effort during manufacturing. In addition, the through hole reduces the contact area between the sole and the base plate, and the weight can be reduced by the amount of the through hole. You can

[0008]

[Embodiment of the invention]

 The inner sole of the shoe shown in FIGS. 1 and 2 is composed of a base plate 1 obtained by cutting compressed pulp using RGP (Refiner Ground Pulp) or the like into a size for mounting one foot of a wearer, so that it fits the sole of the foot. The shape is slightly curved in the width direction.

The front half portion 1a extending from the toe portion of the base plate 1 to the middle position is slightly bulged outward from the rear half portion 1b extending from the middle position to the heel portion, and has a rhombic shape. A large number of through holes 2 are formed in a mesh shape. These through holes 2 are formed at one time by punching after cutting the base plate 1 into the above-mentioned foot shape and keeping the periphery thereof intact. The number of through holes 2 is, for example, 20 to 3 cm × 3 cm. It is preferable to provide 30 pieces. The shape of the through hole 2 is arbitrary, but it is preferable that one side or the diameter is about 2 mm to 3 mm. A piece of paper 3 is attached to the upper surface of the toe portion of the base plate 1.

On the lower surface of the rear half 1 b of the base plate 1, a reinforcing core 4 made of spring steel for reinforcement and a reinforcing cover 5 made of compressed pulp which is slightly thicker than the base plate 1 are provided. The reinforcing core 4 is fixed to the reinforcing cover 5 with rivets 6, and the reinforcing cover 5 is sandwiched between the reinforcing core 4 and the lower surface of the base plate 1 and the peripheral portion thereof is sewn on. , Fixed to the base plate 1.

In a shoe using such an insole, since the front half portion 1a of the base plate 1 is easily bent by the mesh-shaped through holes 2, even if the base plate 1 has high rigidity, it has appropriate flexibility. Can be imparted and durability is not impaired. Moreover, since it is not necessary to provide a hollowed-out portion or a flexible material, it does not take time and effort during manufacturing. Furthermore, since the through hole 2 reduces the contact area between the sole and the base plate 1, and the weight of the through hole 2 can be reduced by the amount of the through hole 2 provided. Can get

The base plate 1 may be made of natural leather or synthetic leather in addition to the compressed pulp.

[0013]

【effect】

 As described above, the shoe insole according to the present invention has a large number of through holes formed in a mesh shape so as to impart appropriate flexibility to the front half portion without impairing the durability of the shoe. You can Further, since it is not necessary to provide a hollow portion or a flexible material, the manufacturing process can be simplified and the cost of the product can be reduced. Moreover, since the weight can be reduced by providing the through holes, the shoe using the insole is easy to walk and wear, in combination with the flexibility.
