Definitions

  • the invention relates to an orthopedic shoe; a thin, flexible and elastic metal blade is provided under the sole with the part closest to the toe of the shoe fixed to the sole and that closest to the heel, free relative to the sole but connected to a pushing device towards the tip of the shoe, hidden in the heel; the force applied to the free end of the blade has an active effect directed towards the ground which causes the tip of the shoe to rise when the foot is lifted from the ground.
  • the object of the present invention is to propose a remedy for the difficulty of wandering these subjects.
  • GB 525 963 discloses a shoe provided with an elastic metal blade placed by one of its ends rigidly in the heel and, by its other end, in contact with or attached to the rear of the sole of the shoe. But said metal blade has the sole purpose of helping the functioning of the shoe, that is to say making walking less tiring for those who have good foot; it is not used for those who have a paralyzed or malformed foot, since it is not an orthopedic shoe and does not allow the automatic erection of the tip of the shoe when the foot is lifted from the ground, to be carried forward.
  • This invention solves the problem of inducing the automatic lifting of the toe of the shoe while the foot of the wearer is released from the weight of the body and must, during the locomotion , be carried forward.
  • the advantages obtained thanks to this invention consist in that the toe of the shoe is lifted automatically each time the shoe is released from the weight of the body; that said lifting may concern the entire width of the sole or, pre-eminently, only half, depending on the infirmity of the wearer's foot; that the lifting can also include a twisting of the sole, which is of great use in the case of equine, varus or supine feet.
  • Fig. 1 shows the overall view of a straight shoe according to the invention, in the non-use position
  • fig. 2 shows the same shoe in the position of use with the foot loaded with the weight of the body
  • fig. 3 shows the same shoe in the position of use with the foot released from the weight of the body as during the advancement phase for walking;
  • fig. 5 shows the same shoe seen from below and whose pushing device acts in the direction of the longitudinal axis of the shoe
  • fig. 5 shows the same shoe seen from below and whose pushing device acts in an oblique direction relative to the longitudinal axis.
  • Its basic constitution includes a shoe of substantially usual shape and structure, where on the lower part of the sole 1 is applied a metal blade 2, thin but robust, flexible and elastic, the part closest to the tip of the shoe is fixed, using known means, to the sole 1, while the other part, which is conveniently restricted towards the end, is free and therefore capable of detaching from the sole under the effect of a force lateral thrust directed downwards and applied at its end; a sub-sole 3 having the function of covering the face of the blade 2 directed towards the ground and of forming a non-slip surface; of a pushing device of said blade 2 comprising at least: a compression type spring 4, housed in a tube 5 fixed in the heel 6, this spring 4 transmitting its compression action to the blade 2 via a piston 7 and a connecting rod 8 shaped so that it is hidden under the central arch 9 of the shoe and connected at one end directly to the piston 7 and by the other at the end 2 'of the blade 2 by means of a hinge 22.
  • a compression type spring 4 housed in a tube 5 fixed
  • said spring 4 has adequate dimensions in relation to the thrust that it is desired to obtain and that it is variable depending on the infirmity and the weight of the person wearing the shoe.
  • the force F1 with which the spring 4 in extension acts on the blade 2 has a component F2 in the free end 2 'of the blade, which component F2 is transverse or oblique to the blade and directed downwards: this determines the uplift of the tip of the shoe.
  • the longitudinal axis of the spring 4 and of the link 8 is either in a plane which has the longitudinal axis YY of the shoe as its outline (example illustrated in FIG. 4), so that the toe of the shoe undergoes a simple lifting by rotation around the trans axis versal XX; either in a plane parallel to it or else oblique (example illustrated in fig. 5) so that the toe of the shoe undergoes a lifting with torsion by effect of the rotation around the axis X'X '.
  • the blade part 2 intended to be fixed to the sole 1 has a variable width extension in order to be extended over the entire width of the sole or else on a part which may be central or lateral with respect to the sole.
