Abstract

The utility model discloses a pair of effort saving shoes without wrinkles, comprising soles and uppers. The utility model is characterized in that each upper is divided into a front, a middle and a back parts, and the middle part which is telescopic is arranged at the bending position between toes and the surface of a foot; the middle part can be made of the materials of elastic tape, rib cloth, nylon fibric, leather bellows, etc., or can be made of a composite material which is composed of leather, artificial leather and elastic fibric. The utility model has the advantages of labour saving for waking by wearing the shoes, no wrinkle on the surfaces of the shoes, good ventilation property, long service life, simple structure, etc.

Description

Shoes without wrinkles and saving effort

The utility model belongs to footwear, and it relates to a kind of footwear that do not wrinkle, and specially refers to a kind of Shoes without wrinkles and saving effort.

At present footwear as leather shoes, sneakers, sport footwear etc., all are that sole and upper of a shoe wrap up comprehensively, the first half of shoes is " pipe " shape.Toe joint wanted crooked when the people walked, and must make this " tube " bending, caused present footwear two big shortcomings:

(1) dress is uncomfortable, walking effort: because walking must make " tube " to bend, promptly the skin above the upper of a shoe is compressed and sole is stretched.According to initial estimate, the road that makes a move is used for about 2 kilograms of power on the wrinkle upper of a shoe, walks one kilometer and will walk 1200 steps, equals to want the power of 2 kilograms of 1200 usefulness, and the time of walking one is long, disadvantages such as pin acid, pin pain can occur.

(2) cause the upper of a shoe crowfoot cracks to fracture: to influence service life: the people walks, and when shoes were crooked, the sole in knee was subjected to pulling force, and upper of a shoe is subjected to an extruding force, and the rubber of general sole is bigger than the skin intensity of upper of a shoe, so the sole crack conditions is less, and the skin of upper of a shoe is difficult to compression, under very big pressure, the skin of upper of a shoe has produced many irregular wrinkles, makes the leather shoes of a pair of light, wearing several times all is wrinkle, time one is long, and upper of a shoe is ruptured, and influences the life-span of whole footwear.For preventing this nest folding of leather shoes, technology (CN89203361.4) that China's (utility model patent communique) once disclosed a kind of " anti-nest laps footwear ".This anti-nest laps footwear are that a long and narrow oblate opening is offered at position easy to break between toe on the vamp and instep, are added with a rubber-like lining under the opening part vamp, and the top of opening is added with the ornamental tape that can cover up oblate opening.Though this leather shoes can overcome the defective of the easy nest folding of existing leather shoes vamp to a certain extent; but because it only is provided with a long and narrow oblate opening on vamp; these both sides to vamp lack effectively protection; and the labor-saving effect is not obvious; simultaneously; its opening part is added with lining and ornamental tape respectively, processes also cumbersome.

The purpose of this utility model just is to overcome the shortcoming of prior art, discloses a kind of comfortable and easy to wearly, is difficult for wrinkle, and processes the technical scheme of more convenient Shoes without wrinkles and saving effort.

The purpose of this utility model is achieved in that and comprises sole, upper of a shoe, it is characterized in that: three parts before, during and after upper of a shoe is divided into, middle is scalable part partly, is located at the knee between toe and the instep, can with make, mode such as bonding or snapping links to each other with forward and backward part.

Because upper of a shoe of the present utility model partly constitutes by three, and be located at knee between toe and the instep in the middle of partly, be telescopic material.It has following advantage:

Unnecessary internal stress when (1) having eliminated walking, wear comfortable especially, light laborsaving during walking, pin phenomenon bitterly can not appear during walk long distances yet.

(2) stressed reasonable, therefore irregular fold when having eliminated footwear walking bending, and the also transposing easily of telescopic resilience thing have improved service life.

(3) because flexible fabric breathability is good, and along with the air-breathing air-blowing effect of walking curved way, the gas permeability in the footwear is improved greatly, help to cure beriberi, eczema.

(4) simple in structure, process more convenient.

Below in conjunction with accompanying drawing, further set forth concrete enforcement of the present utility model.

A kind of structural representation when Fig. 1 is leather shoes for the utility model.

Fig. 2 is intermediate stretchable a kind of plane exploded view partly of upper of a shoe of the present utility model.

See also Fig. 1, it comprises sole 1 and upper of a shoe.It is characterized in that: upper of a shoe be divided into preceding 2, in 3 and 4 three parts in back.Middle part 3 is scalable part, be located at the knee between toe and instep, its material can be elastic braid, rib fabric, RIPSTOP, bellows materials such as (referring to have the leather or the artificial leather composite element of retractility), or the composite of leather, artificial leather and elastic fabric formation.Can with make, bonding or snapping mode links to each other with forward and backward part, processes fairly simple.Because during walking, knee between toe and the instep, partly partly be out of shape bigger at instep than sole, therefore, middle two ends that partly link to each other with sole should be partly narrower slightly than instep, and instep front end partly again should be narrower slightly than the rear end, so middle plane exploded view partly can be used as a kind of long octagon of being made up of three " trapezoidal ", as shown in Figure 2, also can be limit 5, limit 8 in other curve shapes (figure slightly) " trapezoidal " I, the III, in the middle of being equivalent to partly with the end that links to each other on sole two limits; Limit 6, limit 7 are equivalent to two limits of mid portion instep, and they constitute the upper and lower end of " trapezoidal " I, III.And limit 9, limit 10 are equivalent to forward and backward two ends of instep in the trapezoidal II, constitute the upper and lower end of " trapezoidal ".Thereby middle plane exploded view partly is length eight limits as being made up of three " trapezoidal " especially.Telescopic material should be strained during making, make it that certain prestressing force be arranged, when the walking toe was crooked, flexible thing was contraction regularly, like this, just overcame the compression of upper of a shoe with bigger power.And, during walking, make upper of a shoe keep the no wrinkle situation, realized easy to process, laborsaving purpose of not wrinkling.

More than come for example with leather shoes, according to footwear such as above-mentioned, sport footwear, sneakers, also be not unfeasible to those skilled in the art, at this, repeat no more.

Claims

1, a kind of Shoes without wrinkles and saving effort comprises sole and upper of a shoe, it is characterized in that: three parts before, during and after upper of a shoe is divided into, and mid portion is scalable part, is located at the knee between toe and the instep; Can make, mode such as bonding or snapping divides with front and rear portions and links to each other.

2, footwear as claimed in claim 1 is characterized in that: the middle telescopic section material of upper of a shoe can be materials such as elastic braid, rib fabric, RIPSTOP, bellows, or the composite of leather, artificial leather and elastic fabric formation.
