Definitions

  • the invention has the nbjec+ to provide a sole for sandal, clog and similar footwear, which is made up of: a plurality of strips linked to each other along complementary surfaces of articulation, said strips being connected to each other by flexible elements which cross them along transverse through holes formed in said strips; and of two end members rigidly fixed to the two end strips. Tnese end members are so shaped as to complete the sole in the front and back part.
  • the two end members present surfaces which are complementary to the external ones of the end strips, and are fixed thereto even by glueing.
  • the surfaces to which said end members are to be fixed present notches able to house the ends for the anchoring of said flexible elements to the end strips.
  • the sole according to the invention comprises a plurality of strips 3 articulated i.e. linked to each other in order to permit the sole to deform itself when the shoe is being worn; the longitudinal dimensions of the strips 3 change along the sole so as to comply with its outer profile, wkile the cross dimensions are usually - but not necessarily - equal to each other.
  • the strips 3 are linked to each other along complementary surfaces of contact and artioulation, so that each strip presents a convex surface 5 which is in contact with a corresponding concave surface 7 of the adjacent strip, all of them having a section according to an arc of circumference.
  • the strips 3 present internally two transverse through holes 9 for the passage of a connecting flexible element 11.
  • the flexible element 11 is a single one according to the example in the drawing, although two elements may be used in its place with the same result.
  • the ends of the flexible element 11 (or of the two flexible elements instead) are fixed to front and back end-strips respectively denoted by 3A and 3P.
  • the flexible element 11 is constrained with both its ends 12 to +he strip 3P, and its central part 11C rests on the front surface of the strip 3A between the two holes.
  • the two ends 12 may be also welded to each other at 12A.
  • the sole according to the invention is completed in the front and back part with two end members indicated by 13 and 15 respectively, having an arcuate profile; the end members 13 and 15 present surfaces complementary to the external ones of the strips 3A and 3P respectively; besides, they are rigidly fixed - especially by glueing at least - to the relevant end strip 3A and 3B respectively.
  • the member 15 is developed throughout the heel and instep zone, and may be shaped so as to provide an internal support for the foot arch.
  • the end members 15 and 13 present, respectively, canal shaped notches or cavities 17 and 19 for receiving said ends 12 and said central part 11C.
  • the flexible element 11 or the flexible elements result completely inside the sole and thus protected and not visible.
  • a partial upper 20, of a type for sandal or clog may be engaged to the strips 3A, 3, 3P, and it presents, advantageously, forwardsarcuate slots 22, which correspond to the connecting surfaces between adjacent strips; this conformation keeps the upper substantially non-deformed when the sole is curved.
  • the sole according to the invention has the advantages derived by its being articulated and hence flexible, while owing to the presence of the end members 13 and 15, a same sole may be suited to several shoe sizes. To adapt it to a smaller size, it is sufficient to reduce, by suitable means, the front or back projection of said end members which may be overdimensioned, within certain limits, and then reduced to obtain the smaller sizes. Further, as the flexible element 11 is not visible, the aesthetic problems of the product have been solved.
