[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pump which is free from fatigue due to wear and has high wear stability, a shoe last for producing the pump, and a pump insole suitable for mass production of the pump.

[0002]

[Problems to be solved by the prior art and the invention] FIG.
(A)-(C) is explanatory drawing of the conventional pump. FIG. 1A is an explanatory side view of a conventional pump, in which the soles are an outsole 70, an insole 71, an insole 72, and an insole 71, an insole 7;
It is composed of a shank SK arranged between the two,
The sole contact surface S is inclined forward from the heel toward the toe.
Thus, when the wearer stands up, the wearer stands on the tip of the toe, so that the proportions of the entire leg can be shown well.

[0003] However, in the pump having such a structure,
Weight is always added to the toe side of the toe, and the wearer is forced to take an unnatural posture when standing or walking. For this reason, there have been problems such as bending of the toes, causing hallux valgus, tenderness in the soles and toes, and further, slippage of the shoes and beans.

[0004] By the way, in the last for manufacturing a pump as described above, the bottom is rounded (that is, slightly protruded) for the convenience of the manufacturing operation (such as facilitating the hanging operation). Shape. Therefore, in a pump manufactured using the last of the above shape, the contact of the ball wise portion (measurement path portion on the foot contact surface side when measuring the ball girth) BW shown in the bottom view of FIG. The foot surface tends to be concave and the ground contact surface tends to be convex (FIG. 5 (C) (sectional view in the direction of arrow F in FIG. 5 (B)).
reference). Therefore, as shown by the dotted arrow K in FIG. 3C, when the ball wise portion BW touches the ground during standing or walking, the foot swings (that is, the entire pump swings right and left), so that it is stable. It is lacking in properties and causes the feeling of wearing to be further reduced.

The present invention has been proposed to solve the above-mentioned problems, and has a good feeling of wearing (without fatigue,
Further, it is an object of the present invention to provide a pump having high stability during standing and walking, a shoe last for producing the same, and an insole for the pump.

[0006]

As described above, in the last for producing pumps, since the bottom has a round shape, not only the ball-wise portion but also the bottom portion has a rounded shape.
The foot contact surface of the heel also tends to be concave.

[0007] Particularly in pumps, fatigue due to wearing is also caused by the concave shape of the foot contact surface. The inventor of the present invention believes that the above problem can be solved all at once if the heel and the ball-wise part of the pump are flattened and the toe posture during wear can be eliminated. The conclusion was made and the present invention was made.

[0008] That is, the pump of the present invention has a detachable insole, and is formed such that when the wearer stands, the heel contact surface is parallel to the ground, In addition, the thickness of the insole and / or the insole from the instep to the toe is so set that the ball-wise contact surface and the ground contact surface are parallel to the ground when the wearer stands. Characterized by being given to

The last of the present invention is characterized in that the heel portion is formed flat and the ball-wise portion is formed flat.

The last of the present invention for producing a pump semi-finished product without an insole is characterized in that the bottom of the last is formed by adding a thickness corresponding to the thickness of the insole. I do.
Further, the pump insole according to the present invention is used for the pump semi-finished product, and the pump is completed when the pump insole is attached to the pump semi-finished product.

[0011] Here, "standing" means that the shoe sole is not bent when the wearer is walking.
Also, if the heel height is too high, the toes may receive unnecessary pressure, and the effect of the present invention may not be exhibited, and if the heel height is too low, stability may be impaired. Occurs. For this reason, it is preferable that the heel height of the pump of the present invention is usually about 30 ± 5 mm.

[0012]

In the pump of the present invention, since the heel is parallel to the ground when standing, there is no problem that weight is always applied to the toe side. A similar load is applied to the heel. Therefore, when standing or walking, there is no forward leaning posture, no fatigue due to wearing, no unnecessary compression of the toes, bending of the toes or rubbing of shoes. No problems arise.

Since the bottom of the heel portion and the ball wise portion of the last are flat, the heel portion and the foot surface of the ball wise portion of the pump manufactured by this last are also formed flat. Therefore, in the wearer, the heel portion and the ball-wise portion are not subjected to pressure or the like, and no fatigue occurs due to impaired blood circulation or the like.

Moreover, in the pump of the present invention, since the ground surface of the ball wise portion is flat, the ball wise portion comes into flat contact with the ground when standing and walking. Therefore, the pump does not shake right and left, and the stability is high.

In order to make the foot contact surface of the heel parallel to the ground, it is necessary to increase the thickness of the sole from the stepped portion to the toe. In this case, the increase in the thickness of the shoe sole may be realized by giving a thickness to the insole and the insole, or may be realized by giving a thickness to either the insole or the insole. Good.

In the pump of the present invention thus configured, since the insole is removable, it is possible to manufacture the pump according to the footprint of the wearer. In particular, it is preferably used when the function of the foot on the wear surface is immature or impaired.

In the present invention, when a shoe last provided with the thickness of the insole is used, a semi-finished product of the pump is mass-produced. By adjusting the insole according to the wearer's last at the time of sale, for example, it becomes possible to provide a pump with a high feeling of wearing.

(A sectional view in the direction), the foot contact surface S1 of the heel is formed to be parallel to the ground, and supports the heel of the wearer. Note that the shoe sole in the figure is composed of an outsole 2, an insole 3 and an insole 1 (for reference, the shank is shown by SK). Further, as shown in FIG. 7B, the foot contact surface S2 and the ground contact surface S3 extending from the stepped portion including the ball wise portion BW to the toe portion are formed parallel to the ground, so that a feeling of wearing is obtained. Is increasing. In the present embodiment, the ball-wise portion BW is made parallel to the ground by slightly increasing the thickness of the midsole 3.

The insole 1 is detachable, and is made in consideration of the ups and downs of the sole of the wearer. Even if such an adjustment is made, the foot contact surface of the heel portion is formed parallel to the ground. In the insole 1, the basal surface (the surface on the side of the foot) may be made of, for example, natural or synthetic leather, or may be made of a hard / soft composite sponge material.
