Abstract

The utility model relates to a slope-type EVA middle sole. The utility model is characterized in that the sole is composed of an upper layer sole and a lower layer sole. A continuous flange that is low at the front end and high at the rear end is projected at the periphery of the lower layer sole, forming into a sole groove on the sole face; the upper layer sole is made into a sphenoid sole that is thin at the front end and thick at the rear end, and the upper layer sole is inlaid into the sole groove of the lower layer sole. The utility model has the advantages in that the utility model can raise the high quality of the middle sole, simplify process, reduce labor amount and material waste, and save cost.

Description

Slope type EVA middle sole

The utility model relates to footwear, is the end in a kind of footwear made from the EVA plastics.

In the design of existing athletic shoe sole, the middle end that EVA plastics (ethene-vinyl acetate copolymer) commonly used are made sole,, it is with injection mo(u)lding and imposes foaming and handle and make integral structure.Because foaming EVA has good performance aspect the consistency and elasticity requirement, thus comfortable and easy to wear with the sole that make at the end in the EVA plastic shoes, be widely used in shoe industry and make various shoes.In design to sport footwear; only considered to run to jump the comfortable of motion in the past; flexible simple demand, along with the development of sports science, the characteristic demand and the protection of foot motion when the design of proposition sport footwear also must be considered human foot structure and different motion; for example; some sports events needs the sole some to have different hardness, perhaps has different colors; also should consider the manufacture craft that sport footwear is relevant with price and quality simultaneously, as should get rid of local bonding method as far as possible.Make the end in the footwear if will consider above factor, bottom structure can not meet the demands in the then existing EVA footwear.

The purpose of this utility model is in order to propose the end in a kind of improved footwear, both to have made the structure that the end has an integrality in the footwear, can satisfying the specific (special) requirements of foot different motion form to it again.

The utility model of realizing above-mentioned purpose by the upper strata at the bottom of and constitute at the bottom of the lower floor, periphery at the bottom of the lower floor protrudes out the high continuous flange in a low rear end of circle front end, make at the bottom of the upper strata at the bottom of the thick wedge shape in the thin rear end of front end, and make the outer peripheral edges at the bottom of the upper strata identical with the kerve inner peripheral that upper flange surrounded at the bottom of the lower floor, the height of the flange at the bottom of its thickness and the lower floor adapts, and its upper surface is equal when making at the bottom of the upper strata in the chimeric kerve of going at the bottom of the lower floor.The end in the said sloping die bed EVA footwear, can be configured to different hardness or color at the bottom of its EVA upper strata and at the bottom of the EVA lower floor, also can be configured to different hardness or color by different parts at the bottom of giving the system upper strata or at the bottom of the lower floor time.Also can form at the bottom of the described upper strata by at the bottom of the double-deck of different hardness or three layer.

This by the end at the bottom of the upper strata and in the sloping die bed footwear that are combined at the bottom of the lower floor, its preparation method is also fairly simple.At first, mixed EVA plastics are made the idiosome that dwindles by the foaming ratio with injection moulding, then in the chimeric kerve of going at the bottom of the lower floor that the edge raises up of idiosome at the bottom of the upper strata, the operation of foaming and finalize the design of end idiosome in these footwear that assemble, then become the end in the all-in-one-piece slope end formula EVA footwear at last.

Structure by the end in the footwear is as mentioned above seen, owing to be combination and the structure that is combined into one again at the bottom of the multilayer, it is synthetic and have at the end in the footwear of different hardness requirement to make one by the different foaming of EVA plastics ratios, the specific (special) requirements of foot motion when the utility model both can satisfy the characteristics of human foot structure and different motion as far as possible in manufacturing and designing, the end is high-quality in the raising footwear, make work simplification again, reduce the amount of labour and reduce waste of material, save cost.Utilize the utility model can be particularly suitable for developing high-grade sports shoes.

Embodiment of the present utility model as shown in drawings.

Description of drawings:

Fig. 1 is an exploded perspective view of the present utility model.

Fig. 2 is a stereogram of the present utility model.

See by Fig. 1, present embodiment by lower floor at the bottom of 1 and the upper strata at the bottom of 2 constitute, 1 edge protrudes out a circle continuous flange 10 that front end is low, the rear end is high at the bottom of the lower floor, makes at the bottom of the lower floor 1 centre be a kerve; 2 make at the bottom of the wedge shape that front end is thin, the rear end is thick at the bottom of the upper strata, and its size and thickness match with the size of 1 kerve 11 at the bottom of the lower floor and the height of flange 10.See by Fig. 2, at the bottom of the upper strata 2 chimeric go at the bottom of the lower floor in 1 the kerve 11 after, 2 upper surface is equal with the end face of 1 flange 10 at the bottom of the lower floor at the bottom of the upper strata.

Claims
