Definitions

  • the present invention relates to shoe with separable sole and upper.
  • a shoe according to the present invention is of the type in which the sole and the upper are reversibly attached to each other by means of a coupling device which allows their stable association during the assembly phase and during their use, and, when required or desired, also their separation.
  • the main aim of the present invention is to propose a shoe with a separable sole and upper particularly easy to realize and to use without compromising the stability of the coupling between the sole and the upper.
  • the present invention it is possible to manufacture a shoe of the type mentioned above, in which the assembling and disassembling operations of the shoe, that is to say the joining and the separation of the sole with respect to the upper are remarkably simplified so as to enhance the advantages of this type of shoe, as regards both production and the end user- utilization. Moreover, it is possible to ensure a perfect holding of the sole to the upper in any employment condition. Furthermore, the manufacture of the shoe is simplified and this contributes to the reduction of its whole cost.

  • the upper disc (51) and the lower disc (53) feature respective axial extensions (510,530) which act as pins which can be housed in corresponding seats presented by the lower surface (6) of upper (7) and by sole (1) in correspondence to the aforementioned depression (200) .
  • reel (5) can be braked by means of a ring made of friction material (shown in Fig. 12) which acts on the lower face (532) of the disc (53), positioned in depression (200) below the disc (53) .
  • said friction ring is marked by reference "531”.
  • the reel (5) is housed in the seat defined by depression (200) so that a part of the knurled edge (53') is outside and beyond said window (200) in order to allow the manual rotation of reel (5) about axis (x-x) from the exterior of the sole.
  • the lower surface (6) of the upper (7) features a corresponding succession of tubular elements (8) which are also annularly disposed and distanced from one another by a predetermined value so as to form a sort of annular toothing with tubular teeth.
  • the annular profile defined by the tubular elements of the upper (7) is identical to the annular profile defined by the tubular elements (4) of the sole (1) and it presents an interruption (zone without tubular elements 8) in correspondence to the end points (40,41) of the profile defined by the tubular elements of the sole (1) .
  • the thread (9) is used to associate the sole (1) to the upper (7) .
  • the said thread for example, can be made of plastic material, such as PVC or similar materials and it is passed through tubular elements (4,40,41,8) of sole (1) and respectively of upper (7).
  • the movement of the thread (9) through said tubular elements (4,40,41,8) is determined by the rotation of the reel (5) about the axis (x-x) .
  • the reel (5) can be operated from the interior of the shoe instead of being operated from the exterior as in the example described above.
  • the upper axial extension (510) features an axial cavity (512) which can be engaged by a tool such as an alien key (CB) .
  • the upper features a corresponding opening which allows the intervention of tool (CB) .
  • the upper (7) is positioned on the sole (1) so that each tubular element (8) is disposed into depression (10) on the upper part of sole (1) between two tubular elements (4) of the sole, so as to obtain a basically continuous tubular structure which has the profile of an open annular figure (as elements 40 and 41 are in communication with the depression 200) .

Abstract

L'invention concerne une chaussure avec une semelle et une tige séparables. La semelle (1) comprend une surface supérieure (2) sur laquelle une pluralité d'éléments tubulaires (4) sont appliqués de manière à être éloignés les uns des autres selon une valeur prédéterminée. La tige (7) comprend une surface inférieure (6) sur laquelle une pluralité d'éléments tubulaires (8) sont appliqués de manière à être éloignés les uns des autres selon une valeur prédéterminée, la tige (7) pouvant être associée à la semelle (1) par positionnement de la surface inférieure (6) de la tige (7) sur la surface supérieure (2) de la semelle (1) et par insertion des éléments tubulaires (8) de la tige (7) dans les éléments tubulaires (4) de la semelle (1). La tige (7) est fixée de manière réversible à la semelle (1) grâce au passage d'un fil (9) dans les éléments tubulaires de la semelle et de la tige une fois ladite tige positionnée sur la semelle. La chaussure est caractérisée en ce que lesdits éléments tubulaires appliqués sur la semelle (1) sont positionnés selon un agencement annulaire ouvert avec deux éléments tubulaires (40,41), chacun étant positionné de manière à correspondre à une extrémité respective dudit agencement annulaire ouvert et de façon à communiquer avec un logement (200) dans lequel des moyens de manipulation destinés à déplacer le fil (9) sont disposés et agissent.
