Abstract

The invention relates to a relaxation sole (1) has a top face, a bottom face, a sole body containing a housing, which opens at least to the bottom face, on the sub-calcaneus supporting area (2), an elastically deformable structure located in the housing of the sole body, and a skin which covers top faces of the sole body (5) and the elastic structure.

Description

At the bottom of the playshoes and be furnished with the shoes of this sole

Technical field

The present invention relates to a kind of be suitable for to the user provide maintain a good state the sensation playshoes at the bottom of.This sole is used to be set to shoes.

Background technology

The invention particularly relates to the improvement at the bottom of the existing playshoes, more specifically is the improvement to the described sole of French Patent (FRP) No.2765779.

Summary of the invention

The present invention realizes at the bottom of the playshoes by a kind of novelty, it is characterized in that it comprises:

-sole body, it has end face and bottom surface and comprises the cavity that is arranged in inferior calcaneum (sub-calcaneum) support zone, and described cavity leads to the bottom surface at least;

-be arranged on the elastically deformable structure in the cavity of sole body; And

The end face of-covering sole body and the top layer of elastically deformable structure.

In a preferred embodiment of the invention, the cavity of sole body also leads to the sole body end face, and the elastically deformable structure fabrication becomes with the top layer that covers sole body to cooperate to form protuberance a little.

The existence of elastically deformable structure makes easier acquisition produce the inferior calcaneum support of resilience effect in the sole body cavity, and this is corresponding to the pin rear portion of being given prominence to forward, thus the dynamic effect that generation helps the user Gong to maintain a good state.

Especially, when cavity is when running through cavity, can place an elastic construction therein, elastic construction extends on the whole thickness of sole body at least.In patent No.FR2765779, be that the elastomer element by overmolded on sole body makes inferior calcaneum support rubber-like.As a result, in order to obtain bigger resilience effect, the thickness of this element must be quite big.If owing to make, this element provides the elasticity littler than required elasticity, sole will become uncomfortable so, and this is opposite with the purpose that will realize.

In the present invention, elastic construction can have quite big, can produce big resilience effect and avoid the thickness of the problems referred to above simultaneously.Have less than required flexible elasticity even elastic construction unexpectedly presents, under the situation that does not have quite high protuberance, also can not cause any uncomfortable.

For example, elastic construction can be to be made of the deformable material piece.In a modification, elastic construction can be a sandwich construction, for example, double-layer structure, wherein one deck is made of deformable material at least.

In one embodiment of the invention, elastic construction comprises by frothed latex and is dispersed in the deformable material that the granulated cork in the frothed latex constitutes.This material has the hardness less than sole body hardness.

Elastic construction can remain in the sole body cavity by adhesive, certainly, also can use other fixing means under the situation that does not break away from the object of the invention.

The height of the protuberance in inferior calcaneum support zone for example can be preferably about 1mm at 0.1mm in the scope of 3mm.

In one embodiment of the invention, sole comprises one or more inserts, insert is sandwiched in sole body and the support zone under two metatarsals in front or between the top layer in the support zone under the head of last three metatarsals, perhaps is clipped in simultaneously between the top layer in sole body and above-mentioned two zones.

Insert can comprise that a slice or multi-disc become piece cork foam.

Sole body can be made by the plastic material foam, for example be by Shore A hardness be 30 to 35, density is about 100kg/m ³Polyethylene make.

In one embodiment of the invention, the top layer comprises and is coated with film, especially can washes the foam of non-woven membrane, especially polyurethane foam.

Antibiotic and antimycotic processing can be stood in the top layer.

On perpendicular to the cross section on the plane of sole longitudinal axis, the thickness of sole body is constant basically.

In heel area, it is flat end face basically that sole can have, except the protuberance relevant with elastic construction.

The present invention also provides is furnished with the shoes of sole as mentioned above.

Description of drawings

By below in conjunction with the description of accompanying drawing to the non-limiting embodiment of the present invention, the present invention is more prone to be understood, wherein:

Fig. 1 is the schematic plan view according to sole of the present invention;

Fig. 2 is the side view of the sole of Fig. 1;

Fig. 3 is the schematic sectional view along the line III-III of the sole of Fig. 1; And

Fig. 4 is the schematic sectional view on top layer of the sole of Fig. 1.

The specific embodiment

Fig. 1 shown according to sole 1 of the present invention, and it comprises inferior calcaneum support 2, be positioned at the support 3 under two metatarsals in front and be positioned at support 4 under the head of last three metatarsals.For the detail of the position of

relevant support

2,3 and 4, can be with reference to French Patent (FRP) FR2765779, its content is as with reference to introducing in this specification.

In the example shown, inferior calcaneum support zone 2 is the egg type shape basically, and its major axis points to support the place ahead.

Specifically as shown in Figure 3, sole 1 comprises the sole body of being made by polyethylene 5, for example by supplier Podofrance with Podofoam ^The foam that the XA800 title is sold, this foam is can wash and corrosion-resistant, excellent support and pliability, good mechanical strength, good thermal insulation, good resistance chemical reagent can be provided, and soft sense of touch is provided.

Sole body 5 have be arranged in inferior calcaneum support zone 2 run through cavity 6, described cavity leads to its bottom surface 5a and end face 5b.

Cavity 6 receives elastically deformable structures 7, and the elastically deformable structure gives support 2 big resilience effect.

In described example, elastically deformable structure 7 is to be made of the frothed latex piece that comprises granulated cork.

As shown in Figure 3, elastically deformable structure 7 cooperates with top layer 10 on adhering to sole body 5 end face 5b, to form the protuberance 8 that height h is approximately 1mm.

As shown in Figure 4, top layer 10 is to be made of the nonwoven 11 that is lined with polyurethane foam thin layer 12.The 10 pairs of humidity in top layer change relative insensitivity, have good anti-sweat and good antibiotic and antifungal activity.

Elastically deformable structure 7 is inserted in the cavity 6 and by adhesive and remains on wherein.

Support 3 becomes piece cork 15 to obtain with 4 by be provided with two in the corresponding region, and two become the piece cork to be sandwiched between sole body 5 and the top layer 10, as shown in Figure 2.

Certainly, the present invention is not limited to embodiment as mentioned above.

Elastically deformable structure 7 is inserted in replacement in cavity 6, for example can directly inject foam therein.
