Abstract

The utility model mainly relates to a special concave form that is made from the inner surface of a shoe sole. With the special concave sole, a wearer can overcome the defect of easy arch fatigue in walking on a long way, which is equivalent to increase the bending degree of the arch of the wearer actually, particularly for a man on flat foot. Therefore, the defect of the wearer that is unable to have a long walk is overcome, the shoe upper is not easily wrinkled, and the aesthetic of the shoes is protect thereby.

Description

Special concave sole

The utility model relates to a kind of special matrix sole.

Common sole, though what have also has certain matrix, but the face that sole contacts with pin is made level, like this since sole to people's holding power straight up, so to the moment big (referring to the moment that a contact-making surface produces here) of arch, the time one of walking is long, it is tired that arch is felt easily, for flatfoot person, be difficult for walk long distances especially.In addition, present flat heel is because when walking, toe produces bigger bending, so make and the bigger curvature of vamp formation make vamp wrinkling easily.

The purpose of this utility model is to provide a kind of special matrix sole, and it can overcome the defect that flatfoot person is difficult for walk long distances, can also prevent that vamp is wrinkling.

The sole that the utility model provides, its inner surface is made matrix, have two contact-making surfaces with the position, front and back of pin, the centre is recessed or straight, but does not contact with arch, and the curvature in the interior outside of sole can be different, the outside can be done more smoothly, can contact with outside of foot, promptly in the past the lowest part of contact-making surface plays the back contact-making surface and makes straightly, can certainly make the curvature in the interior outside of sole identical.Connect with smooth curved surface between the interior outside.Following indication all be medial surface, comprise embodiment.Preceding contact-making surface is meant the contact-making surface of toe root and sole inside surface, and perk forwards generally can be made linear, shaped form, and the angle on ground is between 5 °～45 °, curved angle is meant the folded angle of its tangent line and ground, specific use can surpass 45 °, is less than 90 ° certainly.Back contact-making surface can be made with preceding contact-making surface similar, perk backward, and angle is 0 °～10 ° between 0 °～30 ° preferably, specific use can surpass 30 °, but must not surpass 90 °, and general and preceding contact-making surface is in sustained height, also difference in height can be arranged certainly.Because preceding contact-making surface has level component backward to the holding power of pin, therefore, the words of not perk of back contact-making surface, also can form a power forward, after having done like this, the suffered moment of arch will reduce greatly, even walk long distances, arch is indefatigability also, in addition, because preceding contact-making surface is upturned, the scope of toe bending when walking reduces, so reduce the formed curvature of vamp is also corresponding, vamp does not just crease easily.Add a bit, the shoe-pad in the sole also can be made this special concave structure equally.

Technological merit and effect: overcome the fatigable defect of walk long distances arch,, in fact just equal to have increased the degree of crook of arch especially for flatfoot person; overcome difficult defect of walking for a long time, in addition, the perk forward of preceding contact-making surface; make vamp not crease easily, protected the aesthetic measure of shoes.

Below in conjunction with accompanying drawing technology contents of the present utility model and embodiment are described in detail.

Embodiment (1): shown in figure (1), the angle on preceding contact-making surface ［ 2 ］ and ground ［ 12 ］, promptly the angle of the direction of ［ 7 ］ and ground ［ 12 ］ is 20 °, back contact-making surface ［ 3 ］ is parallel to the ground, and preceding contact-making surface ［ 2 ］ is connected as figure (1) with smooth curve with back contact-making surface ［ 3 ］, sole ［ 4 ］ is the plane with the contact-making surface on ground ［ 12 ］, and foot plate surface and sole inside surface ［ 13 ］ keep two contact-making surfaces.

Embodiment ［ 2 ］: shown in figure (2), exactly the lowest part ［ 1 ］ of back contact-making surface ［ 3 ］ and matrix sole is in a horizontal plane, promptly parallel with ground ［ 12 ］, and be lower than the preceding contact-making surface ［ 2 ］ that is upturned, other is similar to embodiment (1).

Embodiment (3): shown in figure (3), be exactly that the back adds a heel ［ 9 ］, the perk slightly rearward of back contact-making surface, become 5 ° of angles with ground ［ 12 ］, the anterior toe root ［ 11 ］ of sole outer surface has located to the front upper place one gradient is arranged to get off ［ 10 ］, between desirable 0 °～90 ° of angle that ground becomes, get 40 ° herein, help the starting of pin like this, also more be difficult for making vamp wrinkling, other and embodiment (1) are similar.

Claims

1, a kind of special matrix sole, it is characterized in that the inner surface [13] of sole or the shoe-pad in the sole make matrix, make preceding contact-making surface [2] to the front upper place perk, and the angle of ground [10] is between 5 °～45 °, back contact-making surface can be parallel with ground [12], also can be to the back upper place perk, and ground [12] angle is between 0 °～30 °.

2, special matrix sole according to claim 1 it is characterized in that toe root ［ 11 ］ located to be inclined upwardly to the front portion ［ 10 ］ of the sole outer surface that gets off, and ground ［ 12 ］ angle can be between 0 °～90 °.

3, special matrix sole according to claim 1 is characterized in that former and later two contact-making surfaces can be in sustained height, also can have difference in height.

4, special matrix sole according to claim 1 is characterized in that the curvature in the interior outside of sole can be identical, and it is littler than inboard concavity also can to make the outside, the outside also in the past the lowest part ［ 1 ］ of contact-making surface ［ 2 ］ to play back contact-making surface ［ 3 ］ be straight.

5, special matrix sole according to claim 1.It is characterized in that the shoe-pad in the sole also can make this special concave structure.
