  • the immobilization device described can therefore modify the ability to pivot the rod between a ski practice position, with or without forward bending ability according to the predetermined construction, and an on-rebound position where the rod is free to pivot.
  • Such an immobilization device is satisfactory if the user sticks to the only flexural capacity. forward of the rod which is determined in advance.
  • forward of the rod which is determined in advance.
  • An object of the present invention is to overcome this drawback of the sports shoes described above, and for this purpose proposes a device for immobilizing the upper of a sports shoe which either suitable for a given angular position of a rotary cam controlled by means of a rotary maneuver, to immobilize the upper of the shoe in the postero-anterior direction in order to skiing while simultaneously providing said rod with a certain bending capacity in the direction postero-anterior before blocking, and, for another given angular position of the cam, always guaranteeing the immobilization of the rod in the antero-anterior direction, by providing at the same time as the rod, another capacity for bending or even eliminating the latter.
  • the invention provides, for a position of constant immobilization of the rod in the anteroposterior direction, two possible immobilization positions in the postero-anterior direction determining two different flexural capacities of said rod.
  • Another object of the invention is to allow the release of the rod in pivoting in the direction antero-posterior in view, for example, of facilitating walking or putting on and taking off, in bringing the rotary cam into at least one intermediate angular position situated between the positions previous angular immobilization of the rod, and this leaving the rod a certain capacity to flexion in the postero-anterior direction.
  • the rigid shell sports shoe has, as in the state of the technique constituted by document EP 521 282, a shell base surmounted by a rod capable of pivot in both directions, antero-posterior and postero-anterior, the rod being provided in its zone dorsal, of an immobilization device with respect to the active shell base for at least one of its pivoting direction, via a stop zone obtained on said shell base.
  • the immobilizer is provided with an operating member provided with a rotary cam which acts on a movable element intended to cooperate, for a given angular position of the cam, with the area of hull base stop.

  • the simultaneous implementation of the two movable elements with the two stop zones causes thus immobilizing the upper of the shoe in both directions of pivoting and implementing of a single mobile element with its stop zone only causes the immobilization of the rod in a pivoting direction.
  • the simultaneous disengagement, or retraction, of the two elements moving causes the rod to be released in both directions of pivoting, while the disengagement of one of the movable elements only causes the release of the rod in a direction of pivoting.
  • the rotary cam of the immobilization device is constituted by a plate which, centered on the operating member, comprises at least one circular probing surface having a high working area and a low working area, and the two movable elements of the device cooperate with this feeler surface by means of a feeler member of which they are provided respectively.
  • the feelers of the mobile elements come into contact of the probing surface of the cam at a distance from each other, each on one of the working zones high and low, at opposite points relative to the axis of rotation of the operating member.
  • the plate constituting the rotary cam has two probing surfaces, one on each side, parallel to each other, and having, each, a high work area and a low work area, each moving element coming cooperate with one of the two probing surfaces by means of its probing member.
  • the plate constituting the cam rotary has a single probing surface having, on 360 °, two bosses in the form of arcs of circle of the same height and different lengths defining between them two slots which their are symmetrically opposite with respect to the axis of rotation of the cam and therefore of the maneuver, the bosses constituting the upper work area and the slots the work area low.

  • the two abutment zones of the shell base are formed, one by a vertical notch open upwards and delimited by flexible edges for its porto-anterior immobilization, and the other by its shoulder for its antero-posterior immobilization.
  • the abutment zone formed by the notch is located above that formed by the shoulder. It is covered by the dorsal area of the stem and is intended for cooperate with one of the movable elements which can, as desired, under the action of the rotary cam and for determined angular positions thereof, to retract from said notch or to be inserted between its flexible edges thereby providing a certain possibility of postero-anterior pivoting of the rod or its immobilization in this direction.
  • the flexible edges of the latter can be bring them closer to each other by elastic deformation under the pushing effect of the dorsal area of the rod which covers it and which describes an engaging trajectory on the heel part of the hull base to the place of said notch.
  • the notch thus constitutes the abutment zone of the shell base capable of immobilizing the rod in the postero-anterior direction, and, depending on the angular position given to the rotary cam by means of the operating member, the abutment zone also capable of authorizing some possibility of bending of the rod in the postero-anterior direction.
  • the shoulder constituting the second stop zone is located below and transversely to the latter, also on the heel part of the shell base, and it is the second movable element of the immobilization device, that is to say the one not associated functionally with the notch, which is intended to cooperate with.
  • this movable element bears on the shoulder under the action of the rotary cam, for a position angular given thereof, and in particular when the rod is urged to bend in the antero-posterior direction.
  • the shoe 1 designated overall, and shown in Figures 1 to 3 is of the "front entry" type.
  • This shoe 1 consists of a so-called rigid shell having a shell base 2 provided a sole 6, and surmounted by a rod 3 capable of pivoting thereon in the anteroposterior direction indicated by arrow 20, and postero-anterior indicated by arrow 21, by rotation around lateral connections 4, 4 ', preferably located in correspondence with the articulation of the wearer's ankle, not represented.
  • An immobilizer 10 located on the dorsal area 5 of the rod 3 is provided with a rotary actuator 11, accessible from the outside of the boot shell, to which two movable elements 12, 13, are subject to displacement by means of a rotary cam (not represented) with which it is provided.
  • Two abutment zones 14 and 15 are obtained in the heel part 16 of the shell base 2 in correspondence of the movable elements 12, 13, of the immobilization device 10. In this way, these elements 12, 13, can come to cooperate, after a displacement generated by the rotary cam, with the abutment zones 14 and 15 for at least one given angular position of the rotary cam, i.e. the operating member 11 which is provided with it.
  • These abutment zones 14 and 15 are oriented so as to oppose the pivoting of the rod 3 in the antero-posterior 20 and / or postero-anterior direction 21, when the element 12 and / or 13 cooperates with.
  • the rod 3 is then free to pivot with a certain amplitude, in the two posterior-anterior 21 and antero-posterior directions 20, around its connections 4, 4 ', with respect to the shell base 2.
  • the shoe 1 is with a great flexibility of upper 3 which is favorable for facilitating walking and / or putting on and taking off for example.
  • the abutment zone 14, covered by the dorsal zone 5 of the rod 3 is constituted by a vertical notch obtained in the heel part 16 of the shell base 2.
  • This vertical notch 14, open upwards, is delimited by flexible edges 14 '.
  • These are intended to reciprocally approach each other by elastic deformation, as indicated by the arrows 22, under the pushing effect of the dorsal zone 5 of the rod 3, when the said rod 3 pivots in the postero-anterior direction 21 around its connections 4, 4 ′, and when the movable element 12 is not inserted between them; it is understood that the force applied to the rod 3 must be greater than the resistant one opposed by the flexible edges 14 'to obtain a some bending.
  • Lateral cutouts 17, 17 ′ can optionally be made in the base of shell 2, relatively in front of the heel part 16 thereof, in order to reduce the resistance to bending of the edges 14 ′ of the notch and therefore giving the upper 3 of the shoe a certain flexibility in the anteroposterior direction which is possible under low effort. It's obvious that the extent and shape of such lateral cutouts 17, 17 ', are provided by construction, during the definition of the structure of the hull base 2, as a function of the initial damping desired at rod level 3.
