Description

Cushioned footwear.

Object of the invention

The present invention, as expressed in The statement of this specification refers to a shoe cushioned tread whose essential purpose is to provide the user greater comfort while walking, softening the forces that operate in the heel area, also determining a minor twin muscle strain; all under an insert internal elastic that facilitates a damping effect on the tread and a driving effect by releasing the pressure of said tread.

Background of the invention

Various footwear are known cushioned, such as sports shoes with soles special materials or with soles provided with cameras air dampers and the like; presenting this type of footwear  inconveniences related to excessive cost of realization and a great difficulty of application in non-sports shoes certain types.

On the other hand, footwear of cushioned tread applied exclusively on footwear heel for women and that consist of said heel presents compression and elongation possibilities, normally facilitated by internal springs. In these cases there are inconveniences relative to these spring means deteriorating easily and that the corresponding application is limited to a modality of very determined footwear, being unfeasible in other types of footwear.

We do not know in the current state of the art no cushioned footwear that is based on making a emptying in the inner central part of the sole area corresponding to the heel, providing an insert of flexible material on which a template is arranged internal, as does the cushioned footwear of the present invention

Description of the invention

To achieve the objectives and avoid drawbacks indicated in previous sections, the invention consists of a cushioned footwear that is applicable in footwear that have a sole on which it can be placed or not a template.

Novelly, according to the invention, in the part corresponding to the heel of said sole a hole is made or emptying open towards the upper surface of the sole; housed in said emptying an insert of flexible material that stands out to some extent with respect to that upper surface; from so that if the template is placed as if it is dispensed with it, when pressing on the heel during the tread the insert it is compressed by determining a damping effect, while at releasing said pressure the insert expands determining an effect of drive.

According to the preferred embodiment of the invention, the emptying has a rectangular prism shape with the side rounded back and occupies a large central area of that part corresponding to the heel of the sole, while the insert is a geometry latex block corresponding to the emptying and equipped with roundings that soften the edges in the part that protrudes from the aforementioned upper surface of the sole.

On the other hand, according to different embodiments of the invention, the template is capable of having a zone adapted in the form of recess, projection, tongue or other, whose contour corresponds to the perimeter of the insert to the object that on the tread that adapted area coincides with the edges referral internal emptying.

According to different embodiments of the invention, the aforementioned adapted area of the template is likely to be a protrusion up in flexible templates, a protrusion towards down on rigid templates, and a rocker tab on semi-rigid templates.

With the structure described, the footwear of the invention has advantages relative to that with some means very simple and low cost of realization is provided a damping effect on the tread and a drive effect on the release the pressure of the tread, enabling these effects that the forces operating on the user's heel are softened, reducing the muscular work of the twins. Another advantage important of the invention is that due to its simplicity and to the mentioned configuration or structure, it presents the possibility to be applied in almost any type of footwear.

Then, to facilitate a better understanding of this descriptive report and being an integral part of the same, some figures are accompanied in which with character illustrative and not limiting the object of the invention.

Brief description of the figures

Figure 1.- Represents a perspective view, partial and exploded of a cushioned footwear made according to the present invention.

Figure 2.- Represents a profile view, partial and longitudinally sectioned of the footwear of the previous Figure 1, showing the assembled layout of the components that they appeared in explosion in said figure 1.

Description of an embodiment of the invention

Following is a description of a example of the invention with reference to numbering Adopted in the figures.

Thus, the cushioned footwear of the The present example of the invention can be applied in practically any type of footwear as long as it has a sole 2 on the that a template 3 may or may not be placed on that sole 2 in the inside the footwear.

In the part corresponding to the heel of said sole 2 is made a hole or emptying 4 open upwards, this it is towards the upper surface of the sole 2, as it is appreciate in figure 1.

In that recess 4 a material insert is housed  flexible 1 which, as shown in figure 2, stands out in certain measure with respect to that upper surface mentioned previously.

In addition, by contacting insert 1, you have superiorly a template 3, as can be seen in the figures, of so that in footwear with these characteristics when performing the stepped on insert 1 is compressed by determining an effect damping, while releasing the pressure of the tread the insert 1 expands given a drive effect.

In the present example, as can be seen in figure 1, the recess 4 has a rectangular prism shape with the rounded back side and occupies a large central area of the part corresponding to the heel of the sole 2.

On the other hand, in the present example the insert 1 is a geometry latex heel corresponding to the of the emptying 4 and equipped with roundings that soften the edges in the part that comes out with respect to the aforementioned surface upper sole; not discarding other materials for others realizations

\hbox{vaciado 4.}

In addition, the template 3 may include an adapted zone 5 corresponding to the perimeter of the insert 1 so that in that step that adapted zone 5 coincides with the internal edges of the

 \ hbox {emptied 4.} 

In the present example, that adapted zone 5 of the template 3 consists of a tilting tongue provided for semi-rigid insoles and made using a "U" cut in the back area of the corresponding template, as appreciate in figure 1.

However, in other embodiments the area adapted 5 of the template 3 may consist of a projection towards top applicable in flexible templates, a protrusion down applicable in rigid templates, or be another type of adapted area; also giving the possibility that template 3 lacks the aforementioned adapted zone 5.

Claims (4)

1. Cushioned footwear, applicable in footwear that have a sole on which a template can be placed or not; characterized in that in the part corresponding to the heel (2) of said soleplate a hollow or void (4) is made towards the upper surface of the sole; said insert (4) housing an insert of flexible material (1) that protrudes to a certain extent with respect to said upper surface; so that both if the template (3) is placed as if it is dispensed with, when pressing on the heel during the tread the insert (1) is compressed determining a damping effect, while releasing said pressure the insert is expands by determining a drive effect. 2. A cushioned footwear according to claim 1, characterized in that the recess (4) has a rectangular prism shape with the rounded back side and occupies a large central area of that part corresponding to the heel (2) of the sole, in so much so that the insert (1) is a block of latex of geometry corresponding to that of the emptying (4) and equipped with roundings that soften the edges in the part that protrudes with respect to the aforementioned upper surface of the sole. 3.
