Abstract

The utility model discloses a retractable shoe sole composed of a shoe sole body and a retractable part. The retractable part comprises an internal malleolus retractable part and a lateral malleolus retractable part, and is located between the flank part line on one side and the first toe plantar line and the fifth toe plantar line on the other side. The retractable shoe sole is characterized in that the side face of the retractable part is in a rectangular concave face shape or in a triangular concave face shape, the internal malleolus retractable part has three concave faces, the front face of each concave face is triangular, and the distance between the top corner of each triangle and the bottom center line of the corresponding shoe tree ranges from 8 mm to 12 mm; the lateral malleolus retractable part is composed of large concave faces and a small concave face, the small concave face is located between the two large concave faces, and the concave faces of the lateral malleolus retractable part and the concave faces of the internal malleolus retractable part are arranged to form two corresponding sector structures. According to the retractable shoe sole, the shape of a traditional shoe sole is changed, a retractable part structure is added based on the shoe sole body, and the width of the shoe sole of a children shoe can be adjusted automatically according to the foot changing situation of a user. The shoe sole can automatically retract in the process of walking, abundant activity space is provided for the foot, the shoe is prevented from being too tightened, the foot fatigue is prevented, and shoe fitness and comfort of the shoe can be further improved.

Description

At the bottom of Telescopic shoe

Technical field

The utility model belongs to footwear manufacturing technology field, relates to specifically a kind of design for children's footwear sole and manufacture.

Background technology

Along with the development in epoch, material life abundant, the heads of a family more and more pay attention to child's growth health now, the problem that particularly child's foot is grown.If children wear unaccommodated footwear in the foot stage of development, not only can hinder foot bones to grow, produce flat foot phenomenon, also can increase the chance of ligament injury.So except attractive in appearance, the more important thing is comfortable fitting for the requirement of children's footwear, be conducive to upgrowth and development of children.This makes people improve constantly for the comfortable requirement of fitting of children's footwear series products.In the design or personalized customization process of children's footwear sole, need gradual perfection or improve its comfortableness, foot-suitability.

Because the bone between vola has ligament to connect, ligament can be along with pressure change length.And walk after one day as people, ligament can elongate, pin will show more greatly, the late opisthodetic ligament of sleeping can recover again the original length, so the pin in morning is just aobvious a little bit smaller.And because children are in the foot stage of development, more obvious than adult in this variation on the one hand, common children's footwear cannot well adapt to this situation and become and do not fit, and the foot that has influence on children is grown.At present, improve the method for children's footwear foot-suitability and comfortableness both at home and abroad, and for the comfortable design of children's footwear sole, actual effect is also not obvious.And different children's foot girth of a garment are different, face the foot that different wearers and moment are changing, need footwear to there is good personalized regulatory function, this is particularly outstanding aspect the foot-suitability raising of children's footwear.

Utility model content

For the deficiencies in the prior art, the purpose of this utility model is: at the bottom of a kind of Telescopic shoe is provided, change conventional soles shape, on the basis of sole own, increased pars contractilis structure, can, according to user's foot situation of change, automatically regulate the width of children's footwear sole.And automatic telescopic when walking, and then make foot have abundant move place, prevent that shoes tension from causing medicine, further improve foot-suitability and the comfortableness of footwear product.

For achieving the above object, at the bottom of a kind of Telescopic shoe is provided, be made up of sole itself and pars contractilis, wherein, pars contractilis comprises internal malleolus pars contractilis and external malleolus pars contractilis, and pars contractilis is between flank position line to the first, five toe sole of the foot lines.

Specifically, the rectangular concave in pars contractilis side or triangular shaped recess surface shape, internal malleolus pars contractilis has three concave surfaces, each concave surface front is triangular in shape, triangle drift angle apart from corresponding shoe last or hat block at the bottom of center line 8mm-12mm, external malleolus pars contractilis is made up of large concave surface and little concave surface, and little concave surface is between two large concave surfaces, and the arrangement of external malleolus pars contractilis and internal malleolus pars contractilis is two corresponding sector structures.By described pars contractilis design, can automatically carry out as required appropriateness and regulate, and then improve foot-suitability and the comfortableness of footwear product.And the design of the big or small concave surface of external malleolus pars contractilis can adapt to more complicated careful variation, further improve the foot-suitability of footwear product.

In preferred technique scheme, gap between internal malleolus pars contractilis concave surface is 3mm, gap between the large concave surface of external malleolus pars contractilis and little concave surface is 2mm, external malleolus pars contractilis concave surface is tightr than internal malleolus pars contractilis concave surface, the variation in this is conducive to adapt to wearer while standing vola, and loose between internal malleolus pars contractilis concave surface, can make to walk time, pressure be more naturally convenient to the transition of internal malleolus by external malleolus, and then the medicine of releiving, improve the comfortableness of whole footwear.

In addition the long 25mm-30mm of pars contractilis rectangle concave surface or triangular shaped recess surface, wide 3-4mm.

Accompanying drawing explanation

Fig. 1 is the utility model front schematic view;

Fig. 2 is the utility model side schematic view.

The specific embodiment

Now by reference to the accompanying drawings and specific embodiment, the utility model is further illustrated.

As shown in Figure 1 and Figure 2, at the bottom of a kind of Telescopic shoe, be made up of sole itself 1 and pars contractilis 2, wherein, pars contractilis 2 comprises internal malleolus pars contractilis 21 and external malleolus pars contractilis 22, and pars contractilis 2 is between flank position line 3 to first, five toe sole of the foot lines 4.

Specifically, the pars contractilis 2 rectangular concave in side or triangular shaped recess surface shapes, internal malleolus pars contractilis 21 has three concave surfaces 211, each concave surface 211 is positive triangular in shape, triangle drift angle apart from corresponding shoe last or hat block at the bottom of center line 8mm-12mm, external malleolus pars contractilis 22 is made up of large concave surface 221 and little concave surface 222, and little concave surface 222 is between two large concave surfaces 221, and the arrangement of external malleolus pars contractilis 22 and internal malleolus pars contractilis 21 is two corresponding sector structures.

Wherein, the gap between internal malleolus pars contractilis 21 concave surfaces 211 is 3mm, and the gap between the large concave surface 221 of external malleolus pars contractilis 22 and little concave surface 222 is 2mm.

In addition pars contractilis 2 rectangle concave surfaces or the long 25mm-30mm of triangular shaped recess surface, wide 3-4mm.

More than illustrate the utility model just illustrative; and nonrestrictive, those of ordinary skills understand, in the case of not departing from the spirit and scope that claim limits; can make many modifications, variation or equivalence, but within all falling into protection domain of the present utility model.
