Sole for footwear

Abstract: The sole is of the type that is comprised of a bottom part or sole (1) upon which the top part or front part of the sole (2) couples, the sole (1) having a low top perimetric extension (3) that begins from the edge thereof and whose contour (4) is irregular defining fanciful shapes. The front part of the sole (2) has in its side perimetric wall a shoulder (5) made in the bottom part of said perimetric side wall, whose contour (4) adapts exactly to the contour of the top perimetric extension (3) of the sole (1), all so that upon carrying out the assembly on the front part of the sole (2) on the sole (1), one adjusts perfectly with the other, in such a way that the perimetric side wall of both pieces remain perfectly aligned one being flush with the other.

Description: OBJECT OF THE INVENTION The present invention consists of a sole for footwear of the type comprised of two parts, a bottom part that constitutes the sole itself, and a top part that defines the front part of the sole that forms the support area on which the wearer's foot rests. Now then, the present invention has the purpose of facilitating the adjustment of the top part of the sole on the sole, in such a way that the side surface that comprises the perimeters of both parts, upon being assembled one on top of the other, remain perfectly aligned making flush with each other, in such a way that the side contour has a better appearance. BACKGROUND OF THE INVENTION Manufacturing of soles for footwear which are comprised of two parts, a bottom one which comprises the sole itself, and another top one which comprises the front part of the sole that forms the support area where the wearer' foot rests, is conventionally known, see DE-A-31 08 359. The connection of both parts, is done in such a way that the side surface that comprises the perimeters of said parts, upon being assembled one on top of the other, define a shoulder defined by the difference of perimeters of both parts, whereby the side contour has an irregular appearance. DESCRIPTION OF THE INVENTION In order to overcome the irregularity of the side contour, the bottom part of the sole that constitutes the invention, has a conventional shape in which on the top and in correspondence with the edge thereof, includes a low top perimetric extension whose top edge has different undulations, with which in order to achieve after assembly of the top part of the sole on the sole, both parts remain flush at their side surface, a shoulder that goes from the bottom part to about half of the height of said profile, with a contour equivalent to that of the top edge of the top perimetric extension of the sole, has been made on the top surface or sole and in its side or perimetric wall; in other words, it adapts to the different undulations made in the same. In this way, upon carrying out the assembly of the top part of the sole on the sole, they adjust together in such a way that the perimetric side wall of both parts remain perfectly aligned being flush with each other. This type of assembly considerably improves the quality of the sole and provides a new and attractive aesthetic appearance, as well as a finish of the side contour without shoulders, different from the ones presently known. Hereinafter to provide a better understanding of this specification and forming an integral part of the same, a series of figures wherein the object of the invention has been represented in an illustrative and non-restrictive manner, is attached hereto. BRIEF DESCRIPTION OF THE FIGURES Figure 1 shows an exploded side view of the two parts that comprise the sole object of the invention. Figure 2 shows a plan view of the sole object of the invention, wherein the two parts are assembled. Figure 3 shows a view according to A-B section of the previous figure. DESCRIPTION OF AN EMBODIMENT OF THE INVENTION A description of the invention based on the above mentioned figures is made hereinafter. Just as it was commented on above, the invention consists of a sole of the type that is comprised by a bottom part (1) that constitutes the sole itself and by a top part (2) that constitutes the front part of the sole that forms the support area upon which the wearer's foot rests. The novelty of this invention basically rests on the coupling area between both parts (1) and (2), in such a way that said coupling is carried out effectively at the same time that it offers an improved finish. In order to obtain these objectives, the bottom part or sole (1) of the invention, has a conventional shape in which on the top and in correspondence with its edge includes a low top perimetric extension (3) whose top edge has different undulations (4). On its part, the top part of the sole has in its perimetric or side wall, a shoulder (5) that goes from the bottom part up to about half of the height of said profile, with a contour complementary to the top edge (4) of the perimetric extension (3) of the bottom part of the sole (1). Therefore, the contour of the shoulder (5) of the top part of the sole (2) adapts to the different undulations (4) included in the edge of the perimetric extension (3) of the bottom part of the sole (1) . The thickness of the shoulder (5) of the top part of the sole (2) is equivalent to the thickness of the wall that defines that top extension (3) that starts from the edge of the bottom part of the sole (1); all of this placed advantageously, in such a way that the top part of the sole (2), by means of the shoulder (5) made in the side surface thereof, fits perfectly in the bottom part of the sole, the contour (4) of the extension (3) remaining in correspondence with the contour of the shoulder (5) made in the perimetric side wall of the top part of the sole (2) . This type of assembly considerably improves the quality of the sole and provides a new and attractive aesthetic appearance.

Claims: Sole for footwear of the type that is comprised of a top part of the sole (2) and of a bottom part of the sole (1) upon which the top part of the sole (2) couples, the bottom part of the sole (1) having a low top perimetric extension (3) that begins from the edge thereof, characterized in that the contour (4) of said low top perimetric extension (3) is irregular defining fanciful shapes, the top part of the sole (2) has in its side perimetric wall a shoulder (5) made in the bottom part of said perimetric side wall, whose contour adapts exactly to the contour of the top perimetric extension (3) of the bottom part of the sole (1), all so that upon carrying put the assembly of the top part of the sole (2) on the bottom part of the sole (1), one adjusts perfectly with the other, in such a way that the perimetric side wall of both pieces remain perfectly aligned one being flush with the other. Sole for footwear, according to claim 1, characterized in that the contour (4) of the low top perimetric extension (3) of the bottom part of the sole (1) is provided with a series of undulation type recesses and projections with the exception of the toe piece and the heel.
