Definitions

  • the invention concerns coupling means for arch-supports, ap­plicable to shoe-trees, comprising inclined lamellar bodies, with the front parts curved and pointed and the bases stiffly fixed to the bottom of said shoe-trees or supported on them in seats in which said pointed parts are indented during the idle periods of said shoe-trees.
  • one of the first operating phases provides the application of arch-supports to shoe-trees in order to be able to carry out the following preassembly-assembly phases of the uppers.
  • the toothed ends slightly project from the bottom surface of the shoe-trees, while the opposite ends of the mobile rods are ready to be aligned by means of pressors, through which said teeth are thrust in the arch-supports which are thus fixed to the trees.
  • the rods are withdrawn, the teeth slacken their grip on the arch-supports and the shoe-trees carded with the underside of the upper are sent to the following phases.
  • the scope of the present invention is to eliminate the above problems.
  • the invention as characterized by the claims, solves the problem by means of coupling means for arch-supports, application to shoe-trees, with which the following results are obtained: the lamellar bodies forming the coupling means are in­clined and have the front part curved and pointed; the position of said bodies is towards the point of the shoe-­trees, in the front zone and in opposite direction in the zone of the heel; the lamellar bodies may be of stiff type, indented type or mixed; they are preferably applied in alignment, along the longitudinal central axis of the base of the shoe-trees.
  • the advantages of the present invention mainly consist in the fact that the arch-supports are easily and rapidly fixed to the base of the trees, by simple manual pressure with light longitudinal pull; with the same facility, the uppers complete with arch-supports or finished shoes can be removed from the trees, after the preassembly-assembly and carding operations; said operations, besides being easily and rapidly effectable, do not need any external means for their execution.
  • FIG. 1 show coupling means for arch-supports, appli­cable to shoe-trees, essentially comprising inclined lamel­lar bodies (1) and (1′), with the front parts (2) curved and pointed.
  • the bases of said bodies (1) may be of fixed type (4), or rotating mobile type (5).
  • the bases of fixed type (4) are substantially engaged di­rectly on the bottom (6) of the shoe-trees (7), while those of rotating type (5) are fixed to a small support, preferivelyably cylindrical (8), by means of a trasversal pin (9).
  • the rotating bases (5) are also equipped with small rear lever (10), through which it is possible to make the cor­responding lamellar bodies (1′) rotate in such a way as to indent them under the level of the bottom (6) of the shoe-­trees (7), or make them project above same.
  • the small rear lever (10) presents the sides and ends roun­ded and chamfered in order not to produce, in its projected state, any cut or graff to any surrounding trees, when they are stacked in containers.
  • Each small cylindrical support (8) is pressure-thrust into corresponding, complementary seats, obtained on the bottom (6) of the shoe-trees (7).
  • two lamellar bodies (1) or (1′) are applied in the arch support zone and one lamellar body (1) or (1′) in the heel zone.
  • Application may be made with all lamellar bodies (1) of fixed type, or all or mobile type (1′), or also mixed, preferably aligned to one another along the longitudinal axis of each shoe-tree (7).
  • the arch-supports (11) are first supported to said lamellar bodies projecting from the arch support zone and pressed on them with a light backward movement.
  • the lamellar bodies (1) and/or (1′) penetrate the arch-supports and are coupled to same by means of their front curved pointed parts.
  • the heel part is then pressed on the corresponding lamellar body, or bodies (1) and/or (1′) until it is wedged on same.
  • the shoe-trees (7) may be easily removed from the uppers, removing first the rear part then the point.
  • the lamellar bodies (1) and/or (1′) are removed from the notches of the arch-supports, produced by them during application, without causing any tears, and the existing notches are subsequently re-covered with glueing of the lining.
  • the solution with the fixed lamellar bo­dies (1) is the most economical, it may be less preferable since, at the end of use, the shoe-trees (7) are generally stacked in a container.
  • the pointed lamellar bodies (1) may cause cuts, scratches or at any rate damage to the surrounding shoe-trees (7). If this must be pre­ vented, on the shoe-trees (7) are applied the mobile lamel­lar bodies (1′), which, by means of the small rear lever (10), may be made project during use and made indent du­ring stacking periods.
  • the small rear levers (10) disappear below the level of the bottoms (6) of the shoe-trees (7), in the spe­cial niches (14).
  • the cutting lamel­lar bodies (1′) are made disappear below the same level of the bottoms (6), while the small rear levers (10) project from it; this does not cause any damage, however, thanks to their rounded, chamfered shape.
  • At least one return spring (15) is placed between the rotating bases (5) and small supports (8) and put in tension.
