Abstract
The utility model relates to a sole structure improvement. A local body or the integral outer rim are provided with an edge portion, a surface layer is adhered on the outer surface of the edge portion, and the rigidity of the edge portion is greater than the rigidity of the body. Since the edge portion has larger rigidity, the capability of compressive resistance or extruding resistance is greater, the effect of restoring from deformation under force to initial state is great, thereby ensuring the surface layer not appearing drape or bulge.
Description
[technical field]
The utility model is about a kind of footwear sole construction, refers in particular to identical or similar footwear such as applying to sneakers, leather shoes, playshoes, and the whole outer fringe surface of this sole is provided with cortex or layer of cloth.
[background technology]
See also Fig. 1 and Fig. 2, present common sole (10), for example in the end, be to go out a body (12) by PU material or EVA material foaming, outer rim that in addition can this body (12) and lower surface are sticked and one of are constituted superficial layer (14) by leather or cloth.
See also Fig. 2 and Fig. 3, this superficial layer (14) can form fillet (16) at corner location after fitting with this body (12).In the middle of the end combine with a big end (19), then the fillet (16) of sole (the middle end) (10) and greatly understand not driving fit between the end (19) and form an opening columnar structure is so for whole outward appearance, obviously not attractive in appearance.
In addition, the superficial layer (14) that all is sticked in the side of sole (the middle end) (10) and bottom surface forms waste of material, and locate at fillet (16), the surface of superficial layer (14) is easy to generate wrinkle or protuberance (18), particularly after the effect of be under pressure (F), be more prone to produce the problem of wrinkle or protuberance (18).
[summary of the invention]
In view of the superficial layer of general footwear sole construction produces the problem of wrinkle or protuberance easily when making and use, the utility model is the footwear sole construction that a kind of innovation is provided, in order to solve the problem that prior art produced.
The purpose of this utility model is that a kind of footwear sole construction improvement is being provided, and it has the effect that makes the superficial layer that is coated on this sole outer rim not produce wrinkle and protuberance.
The utility model is achieved in that its sole is to comprise a body, is provided with one side portion in the whole or local outer rim of this body, and a superficial layer is sticked in this limit portion side edge surface, and wherein the hardness of this limit portion is greater than the hardness of this body.
Advantage of the present utility model is: because this limit portion has big hardness, so the ability that compressive resistance/resistance to compression is squeezed is preferable, the effect that returns back to original state behind stress deformation is better, it is hereby ensured that this superficial layer does not produce wrinkle or protuberance.
In addition, manufacture process of the present utility model is to utilize the strength of body foaming, pushes this superficial layer to the die cavity wall, and then makes this superficial layer form smooth structural form in this limit portion outside, so this superficial layer is smooth-going more attractive in appearance.

[specific embodiment]
See also Fig. 4 and Fig. 5, the end footwear (20) that the utility model disclosed comprise a body (22), one side portion (24) and a superficial layer (26).Wherein this body (22) is all made by expanded material with this limit portion (24), is for example made by the PU material, and the material that is disclosed more than the thought is not as limit as illustrative purposes only.In addition, this body (22) can be identical or different system material with this limit portion (24).
It should be noted that this limit portion (24) is the element of a columnar structure, it cements in the outer ledge of this body (22).This limit portion (24) can adhere to partial lateral or whole outside of this body (22), and in present embodiment, this body (22) does not only set this limit portion (24) in the front end local location.
In addition, the hardness of this limit portion (24) is greater than the hardness of this body (22).The characteristic that it can utilize different materials itself makes this limit portion (24) and this body (22) form different hardness respectively.In addition, can utilize forming technique, make this made limit portion (24) of identical or different material and this body (22) have different hardness.Wherein the hardness of this limit portion (24) is big, has preferable compressive resistance/resistance to compression and squeezes ability, is higher than this body (22) so this limit portion (24) reverts back to the ability of original state after stressed.This superficial layer (26) is the outer surface in this limit portion (24) of being sticked.This superficial layer (26) can be leather, cloth or other analog.
See also Fig. 5 and Fig. 6, when this sole (20) is subjected to an external force (F) effect, though this body (22) all can produce the extrusion distortion with this limit portion (24), but because this limit portion (24) has preferable recovery capacity, so can impel this superficial layer (26) to revert back to original state simultaneously, and not stay wrinkle or protuberance.
The evenness that original state can have influence on this superficial layer (26) that combines of this limit portion (24) and this superficial layer (26) from the above.Therefore manufacturing of the present utility model can be reached according to the following stated.
See also Fig. 7, the producer can produce this limit portion (24) earlier and combine with this superficial layer (26), and this limit portion (24) of combination places in the die cavity (42) of a mould (40) with this superficial layer (26).Follow limit portion (24) the interior zone injecting frothing material in this die cavity (42) to form this body (22).It should be noted that, the expansion molding process of this body (22), meeting and this limit portion (24) good bond, and push the combination of this limit portion (24) and this superficial layer (26) wall of this die cavity (42) to, then this superficial layer (26) is subjected to this mould (42) wall and the effect of mould temperature thereof and produces the ironing effect.In other words, this superficial layer (26) has smooth-going original state.
Be to make the superficial layer (26) of sole (20) be difficult for producing wrinkle or protuberance,, meet user demand so can make the outer surface of sole (20) smooth-going more attractive in appearance in manufacture process or use with, the structure that the utility model disclosed; In addition, manufacturing of the present utility model is easy, so can satisfy the manufacturing demand.Superficial layer (26) only is sticked at the lateral surface of sole (20) again, thus can save material, simultaneously again because do not commonly use the radiused configuration of structure, so more driving fit and outward appearance are better for a utility model and a big bear building-up credit union.
See also Fig. 8 and shown in Figure 9, the made sole (30) of the another embodiment of the utility model is the combination that comprises a body (32) and one side portion (34), wherein the outside of this limit portion (34) more forms one of the structure avris (38) of kicking up, make the whole formation of sole (30) can coat the structure of sole, the hardness of this limit portion (34) is greater than the hardness of body (32) in addition.The outer surface of this limit portion (34) superficial layer (36) that has been sticked again.
See also shown in Figure 10, the manufacturing of present embodiment can be earlier and limit portion (34) that have avris (38) higher with hardness combine with superficial layer (36), and be placed in the die cavity (52) of a bed die (50), bed die (50) top correspondence is provided with one and has mould (60) on the avris (68).
See also shown in Figure 11, when mold (60) and bed die (50) closing, and inject the material that constitutes body (32) at limit portion (34) inner space, the thrust that then can utilize body (32) to expand, push limit portion (34) and superficial layer (36) to bed die (50) internal face, and the avris (68) of mold (60) leans on mutually with the avris (38) of limit portion (34).Utilize the mould temperature of bed die (50), can make superficial layer (36) smooth in limit portion (34) surface.
