Description

[Detailed description of the invention] [Industrial application field] This invention mainly relates to an insole for shoes that is formed by placing and fixing the contact surface shape of the foot (hereinafter referred to as ball heel shape) on the insole material. It is something.

[Conventional technology]

Conventionally, in shoes using this type of insole, especially in medium-to-high size women's shoes, when fixing the heel to the external bottom of the heel, it is done by inserting a nail or screw, etc. from the insole side toward the heel. was.

[Problem that the invention attempts to solve]

However, if you fix the heel using the above method,
The following problems arose.

(1) Since this type of insole has some cushioning properties, it is difficult for nails, screws, etc. to be completely effective, and a stable fixation of the heel cannot be obtained.

(2) The heads of the nails and screws inserted as described above dig into the synthetic rubber or synthetic resin forming the ball heel, damaging the shape of the insole and making it uncomfortable for the foot.

(3) When manufacturing shoes made using the Bolognaise method or Platz method using such an insole, in order to hide the heads of nails and screws, it is necessary to cut or penetrate the insole that is the contact surface of the insole. In addition to inserting nails and screws, it becomes necessary to lay other insoles on top of the nails and screws, which takes a lot of effort and time, increases costs, and also deteriorates the appearance of the shoe.

[Means for solving problems]

This idea is based on a shoe in which a ball-heel shape is placed and fixed on the rear half of the midsole material, and a heel fixing nut that has an integrated collar with a claw protruding from the bottom surface at a position corresponding to the heel of the midsole material. The insole for shoes is characterized in that the foot part of the shoe is fitted over the heel part which overlaps with the lower part of the foot part.

[Effect]

When using the above-mentioned insole, the heel fixing nut with a wide brim has a claw on the underside of this brim that sticks into the insole material to prevent rotation, and the foot of this nut is under the insole material. This heel fixing nut is inserted all the way to the heel part that is attached to the side, and it stabilizes not only the heel fixing nut but also the heel part, so fixing the heel can be easily and quickly done by inserting the bolt from the ground side. Not only can this be done reliably, but the bolt is screwed into the foot of the nut to prevent a part of this bolt from digging into the synthetic rubber, synthetic resin, etc. that forms the ball heel, and the inside of the bolt has a good feel for the foot. The shape of the sole can be maintained stably, and the shoes can be manufactured easily without damaging the insole or having to install the insole twice, reducing costs. Appearance can be significantly improved.

〔Example〕

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

1 to 7 show one embodiment of this invention.

The insole for shoes in this embodiment is constructed as follows. In other words, as shown in FIGS. 1 to 3, this insole has an insole material 1 as a base made of cellulose fiber or the like, and a cushioning material is provided on the rear half surface of this insole material 1. A ball heel shape 2 formed to match the contact surface of the foot is placed and fixed using good synthetic rubber or synthetic resin, and a shank 4 is placed in the same plane as the center band of the upper surface on the bottom surface of the rear half of the insole material 1. In the midsole to which the backer board 3 made of a material such as pulp fiber is fixed, the following nut 5 is attached to the heel portion of the midsole material 1. There is.

The above nut 5 is constructed as follows.
That is, as shown in FIGS. 6 and 7, the nut 5 is made of a light metal (such as aluminum alloy) or an engineering plastic that has excellent heat resistance, wear resistance, and insulation properties. , a thin circular brim 6 with a predetermined diameter is attached to the upper part.
is being formed. A cylindrical foot portion 7 is vertically provided at a position directly below the center of the collar 6, and a screw hole 8 having a standard diameter is screwed into the inner diameter surface of the foot portion 7. On the lower surface of the collar 6, anti-rotation pawls 9 are provided to protrude at intervals in the axial direction.

As shown in FIGS. 4 and 5, the nut 5 as described above has a foot portion 7 attached to the heel portion of the insole material 1 directly below the ball heel shape 2 described above.
After it is inserted and stored, the collar 6 is pressed against the surface of the inner sole material and the nail 9 is driven into the lower surface of the inner sole material, so that it is fixed in a state where it is prevented from falling off and rotating, and the entire structure is fixed. Composed at the bottom of the bulk body.

In the above configuration, when the heel (not shown) is to be fixed after inserting the insole into a shoe (not shown), the upper part of the heel is brought into contact with the external bottom surface of the shoe, which corresponds to the heel, and the insole is attached. By screwing a bolt (not shown) from the ground side into the screw hole 8 of the nut 5 attached to the heel and tightening it, the nut 5 has its collar 6 pressed against the upper surface of the insole material 1. Furthermore, each claw 9 is driven into the surface of the midsole material 1 to prevent both falling off and rotation, so that the heel can be easily and quickly and reliably fixed. In this case, since the leg portion 7 of the nut 5 is formed into an elongated body, even if a bolt is screwed in from below, its tip will not protrude to the upper part of the screw hole 8. Therefore, it is possible to prevent the bolt from biting into the synthetic rubber, synthetic resin, etc. forming the ball heel.

FIGS. 8 and 9 show other embodiments of this invention.

Insole material 1 constituting the insole in this embodiment,
The main parts of the ball heel shape 2, backer board 3 with shank 4, and nut 5 are completely the same as in the previous embodiment. However, in this embodiment, the nut 5 is attached to the inner sole material in advance when the inner sole is formed.
After the foot part 7 is inserted into the heel of the back car board 3 with the shank 4 located directly below the shank 4, the shank 4 is pressed against the collar 6 and the nail 9 is driven into the underside of the shank 4 to prevent it from falling off. It is fixed in such a way that it is prevented from rotating, and is thereby formed at the inner bottom of the unit.

In the above configuration, when the insole of this embodiment is inserted into a shoe (not shown) and a heel (not shown) is fixed, the heel is attached to the outer bottom surface of the shoe, which corresponds to the heel, as in the previous embodiment. The upper part of the nut 5 is in contact with the upper part of the shank 4, and a bolt (not shown) is inserted from the ground side into the screw hole 8 of the nut 5 attached to the heel of the inner sole and tightened. It is pressed against the top surface, and each claw 9 is driven into the surface of the shank 4 to prevent it from falling off and rotating, so it can be easily and quickly heeled.
And it can be fixed securely. In this case, the foot 7 of the nut 5 is elongated, so even if the bolt is screwed in from below as described above, its tip will not protrude to the top of the screw hole 8, and therefore the bolt will form a ball heel. This prevents it from digging into the synthetic rubber, synthetic resin, etc. Note that since the nut 5 of this embodiment is housed at a deeper position than the nut 5 of the previous embodiment, there is an advantage that the heel can be fixed in a more stable state.

[Effect of idea]

As explained above, this invention is based on an insole for shoes that forms a ball heel shape, by attaching a heel fixing nut with a flange at a position corresponding to the heel of the insole. When fixing a heel, the heel can be fixed easily, quickly and reliably by inserting a bolt from the ground side, and in addition, a part of the bolt forms a ball heel using synthetic rubber, synthetic resin, etc. This prevents the insole from digging into the insole, stably maintaining the shape of the insole that feels good against the foot, and making it easy to manufacture shoes without damaging the insole or having to install the insole twice. This has the effect of reducing costs and greatly improving the appearance of shoes.
