Definitions

  • the present invention relates to an apparatus for acquiring the morphology of a foot, in order to realise an orthosis for a foot or a shoe or a form (so-called "last") or a shoe component or an insole or a similar element.
  • a scanning apparatus comprising a plate made of transparent material onto which laying the foot and optical acquisition means placed below said plate for acquiring, from below, the image of the sole of the foot laying on it.
  • a limitation of such an apparatus is caused by that the soft tissues of the foot, which are pressed against the plate, are deformed, thus taking a substantially flat configuration that does not correspond to the actual morphology of the foot.
  • Such an apparatus does not allow to effectively acquire the morphology of the foot in a neutral position, which corresponds to the neutral configuration of the foot in terms of subtalar articulation, namely the optimal configuration of the bones with which the foot should support the body weight.
  • an apparatus of the above-indicated type exclusively allows the acquisition of the image of the foot lying on a horizontal plane. In fact, through such an apparatus it is not possible to acquire the morphology of the foot positioned so as to simulate the posture taken by the foot itself inside a heeled shoe.
  • an apparatus for the foot scanning comprising a front platform and a rear platform movably connected to a supporting structure instead of a single laying plate.
  • a posture with the raised heel similar to that taken, for example, by the foot inside a heeled shoe.
  • US 2010 / 0229422 shows a supporting surface of the foot such that the relative vertical position between a front portion and a rear portion is adjustable.
  • this apparatus is not able to overcome the inconvenience regarding the deformation of the soft tissues of the foot previously described, since each of the front platform and of the rear platform causes the uncontrolled deformation of the soft tissues of the foot laying thereon. This is due to the fact that the supporting surface is substantially rectilinear in the transverse direction, i.e. in the lateral-medial direction, and the soft tissues adhere on such a surface depending on the position of the foot and on the applied load.
  • the soft tissues are not supported and held in the lateral-medial direction. Moreover, such an apparatus does not allow acquisition from below of the morphology of the foot.
  • US 2001/0030297 describes a device configured to hold a foot in an unloaded condition and in a flat position, i.e. associated with a non-heeled shoe.
  • an object of the present invention is to provide an apparatus for acquiring the morphology of a foot in the context of a solution able to limit the deformation phenomena of the soft tissues of the foot, typical of traditional apparatuses.
  • Another object of the present invention is to provide an alternative solution of an apparatus for acquiring the morphology of a foot allowing the bones of the foot to take the most suitable configuration for the user, for example the so-called neutral position in the podiatric field or one specific position to compensate and/ or to correct specific problems of the biomechanical type and to hold the foot in such a position during the process of acquisition.
  • a further object of the present invention is to provide an apparatus for acquiring the morphology of a foot in order to realise orthoses for the foot to be used with heeled shoes or in order to realise a shoe with a personalized heel, in which the morphology of the shoe and the dimensions of the heel, with particular reference to the height thereof, can be optimized according to specific biomechanical or ergonomic needs of a user.
  • Another object of the present invention is to provide an apparatus for acquiring the morphology of a foot able to make the foot to take the postures taken by it during a race or a walk.

  • the position of the foot can be either flat, as previously mentioned, or with the raised heel to simulate a heeled shoe; for each position of the foot a plurality of configurations of the feet bones are possible, e.g.
  • the connecting means can adjust the vertical height of the flexible element with respect to the horizontal plate in one or more peripheral points of the flexible element itself. In this way it is possible to adjust the distribution of the soft tissues and the configuration of the bones in a controlled and particularly precise way. In particular for realising shoes with tailored heels not applying harmful loads to the foot, it is important being able to accurately adjust using a single tool the position of the foot, the configuration of the bones and the distribution of the soft tissues. Such data are usable for producing orthotics or shoes with improved comfort.
  • the movable support for supporting and/ or defining an abutment for the heel of the foot with respect to the forefoot is bar-shaped and it is arranged to protrude in the position extracted from a medial side and from a lateral side of the foot for not interfering too much with the image acquisition from the perspective of the sole of the foot.

  • Acquisition apparatus 1 provides the effective acquisition of the foot positioned against horizontal plate 5 or with the heel raised with respect to the forefoot.
  • Acquisition apparatus 1 indeed, provides the positioning and stably holding of the foot in a position with a heel raised with respect to the forefoot, and the acquisition of the morphology of the foot in such a posture.
  • the data thus acquired may be used to manufacture orthoses for heeled shoes or the structure of the sole of a custom made footwear or a shoe or a form (so called 'last') or a footwear component or an insole or the like.
  • Acquisition apparatus 1 described above is easy to use and can be completely automatized.
  • connecting means 14 of flexible element 8 with respect to support frame 2 may be managed by a control unit not shown in the figures and connected to the connecting means.
  • the actuation of mobile support 26 between the retracted configuration and the extracted one and vice versa may be caused by the actuation of rear portion 12 of flexible element 8 with a simple and easy-to-use solution.
  • Acquisition apparatus 1 is very flexible to use providing the acquisition of the real morphology in substantially any posture of the foot, and in particular in that wherein the heel is raised with respect to the forefoot, thus overcoming the drawbacks of the traditional apparatuses.
  • support frame 2 may be configured in such a way to house all mechanical and/ or electronic devices needed for the functioning of acquisition apparatus 1.
  • Optical acquisition scanning apparatus 1 for a foot described above may be modified with many modifications and variants within the scope of protection of the following claims.
