By adopting the technical proposal, the sole overcomes the defect of the prior art to provides a novel sole with changeable width according to the change of a foot.

Description

The sole of changeable width

Technical field

The utility model relates to a kind of sole, is meant the sole of varying width at any time especially.

Background technology

The sole of present footwear is of a great variety, the footwear that sounding is arranged, luminous footwear are arranged, have the band pulley etc., the footwear of the various patterns of being made by these soles bring more selection to the consumer, made things convenient for vast consumer's selection, and given the consumer enjoyment of more life, but these all are some auxiliary functions, the crowd who is fit to is not very wide, and does not improve the comfort level that the people wears footwear.

Present people likes wearing playshoes, and its main purpose is convenient and comfortable, and playshoes is adapted at wearing any season; But it also exists some shortcomings, and as in one day, people's pin can change, particularly people's pin is wideer than the morning afternoon time, the half sole position of pin particularly, and the size of footwear does not change, at this time people wear footwear and will feel tightly, and are uncomfortable; When some people went to buy footwear in addition, the socks of wearing on the pin were thinner, and it is proper to try footwear like this on, but somewhat cold when weather, and when wearing thick socks, these footwear are just very tight like this, and it is also uncomfortable to walk.Also there is not a kind of solution at the problems referred to above.

Summary of the invention

The utility model has overcome the deficiency that prior art exists, provide a kind of can be according to the variation of pin, the novel sole of appropriate change sole width.

For achieving the above object, the utility model provides following technical scheme: a kind of sole of changeable width, the connecting portion that includes the corresponding district of ball of foot, the corresponding district of heel and connect above-mentioned two districts, it is characterized in that: the corresponding district of the ball of foot of described sole upper side vertically is provided with and stretches fluting, and the bottom surface of described sole is provided with the convex tendon corresponding with developing tank.

The utility model is by being provided with developing tank and convex tendon, and its purpose is exactly the leeway that has an expansion to sole, and by mechanics principle, after the both sides of sole were applied in outside pulling force, developing tank will stretch to both sides, thereby realizes the function of broadening sole.

Further setting of the present utility model is: described developing tank has two, is separately positioned on the both sides of sole upper side longitudinal centre line, and the convex tendon on the corresponding sole bottom surface also has two; Described developing tank becomes " V " shape with the cross section of convex tendon.

In such scheme, the purpose of both sides that developing tank and convex tendon is arranged on the longitudinal centre line of sole is the wearing and tearing that reduce convex tendon, prolong the service life of sole, concrete principle is, because the stressed emphasis of longitudinal center's line position of the bottom surface of sole, so the wearing and tearing of this position are the most serious, and convex tendon is avoided this position and is provided with and just can realizes the purpose that reduces to wear and tear; Developing tank becomes " V " shape with the cross section of convex tendon in addition, such scheme, and its varying width is more reasonable.

Below in conjunction with accompanying drawing the utility model is further described:

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is the A-A cut-away view of Fig. 1;

Fig. 3 is the B-B cut-away view of Fig. 1.

The specific embodiment

As depicted in figs. 1 and 2, a kind of sole of changeable width, include the corresponding district 1 of ball of foot, corresponding district 3 of heel and the connecting portion 2 that connects above-mentioned two districts, in the utility model embodiment, the corresponding district of the ball of foot of described sole 1 upper side vertically is provided with and stretches fluting 12, the bottom surface 14 of described sole is provided with the convex tendon 11 corresponding with developing tank 12, the utility model is by being provided with developing tank 12 and convex tendon 11, its purpose is exactly the leeway that has an expansion to sole, pass through mechanics principle, after the both sides of sole are applied in outside pulling force, developing tank 12 and convex tendon 11 will stretch to both sides, thereby realize the function of broadening sole, satisfy people's demand.

In the utility model embodiment, described developing tank 12 has two, be separately positioned on the both sides of sole upper side 13 longitudinal centre lines, convex tendon 11 on the corresponding sole bottom surface 14 also has two, here the purpose of both sides that developing tank 12 and convex tendon 11 are arranged on the longitudinal centre line of sole is the wearing and tearing that reduce convex tendon 11, prolong the service life of sole, concrete principle is, because the stressed emphasis of longitudinal center's line position of the bottom surface 14 of sole, so the wearing and tearing of this position are the most serious, and convex tendon 11 is avoided this position and is provided with and just can realizes the purpose that reduces to wear and tear; Described developing tank 12 becomes " V " shape with the cross section of convex tendon 11, such scheme, its varying width is more reasonable, " V " shape developing tank 12 is just the same with spring with convex tendon 11, when the power that is subjected to when the sole both sides reaches certain, " V " shape developing tank 12 just launches with convex tendon 11, so that increase the width of sole.Certainly in the utility model embodiment, the number that developing tank 12 and convex tendon 11 are provided with and the position of setting also can be otherwise, as are provided with four or one, and the position also can be different with the foregoing description in addition.

Claims (3)

1, a kind of sole of changeable width, the connecting portion that includes the corresponding district of ball of foot, the corresponding district of heel and connect above-mentioned two districts, it is characterized in that: the corresponding district of the ball of foot of described sole upper side vertically is provided with and stretches fluting, and the bottom surface of described sole is provided with the convex tendon corresponding with the developing tank position.

2, the sole of changeable width according to claim 1 is characterized in that: described developing tank has two, is separately positioned on the both sides of sole upper side longitudinal centre line, and the convex tendon on the corresponding sole bottom surface also has two.
