Definitions

  • the present invention relates to a ski boot consisting of a lower part comprising the sole and intended to surround the foot and the heel and of a rod-shaped rod articulated on the lower part and having, at the rear, a deep notch open towards the bottom allowing a wide tilting of the collar towards the rear, the region discovered by the notch being occupied by a cover also articulated on the lower part of the shoe at two opposite points situated below the articulations of the collar , the collar and the cover being interconnected by a rigid arm.
  • the support is made by means of the arm connecting the collar to the cover, by the cover itself and by a pawl resting on the lower part of the shoe.
  • the support of the pawl on the lower part of the shoe also gives the desired inclination to the upper of the shoe.
  • This construction therefore requires a cover which is sufficiently resistant and rigid to withstand the pressure of the leg and the reaction on the axis of the pawl.
  • This requires the use of a sufficiently thick plastic material and the articulations of the arm and the pawl on the hood which are largely dimensioned.
  • the link arm and the pawl form unsightly protruding external elements.
  • the present invention aims to unload the hood and improve the aesthetics of the shoe.
  • the shoe according to the invention is characterized in that it comprises a second rigid arm connecting the axis of articulation of the first arm to the hood to the lower part of the shoe, at a point located above the heel, the axis of articulation of these two arms between them being slidably mounted in a slide secured to the cover and situated in a plane parallel to the plane of oscillation of the collar and the cover on the lower part of the shoe, the two arms forming a toggle locking the collar in position of use when the cover is pushed back to cover said notch.
  • the hood is no more than an actuating member which is pulled back or pushed forward to actuate the toggle, that is to say respectively unlock and lock it. this.
  • the rear support on the collar is transmitted directly to the rigid heel part of the inner part of the shoe by the knee pad.
  • the latter preferably made of metal, can, under reduced dimensions, easily withstand compression and tensile forces.
  • the cover when folded back in the notch of the collar, it completely covers and hides the toggle joint ensuring the continuity of the collar which is thus free of protrusion or external protuberance.
  • the knee lever also makes it possible to eliminate the pawl of the prior art.
  • a certain flexibility can be given to the collar by using toggle arms having a certain elasticity in traction and possibly also in compression.
  • This elasticity can be achieved by means of a piston sliding in a cylinder and subjected to the pressure of a spring or two opposing springs.
  • Figure 1 shows a view in the open position of the cover, partially in section.
  • Figure 2 shows the same shoe in the closed position of the hood.
  • the shoe shown comprises a lower part 1 in the form of a plastic shell with variable volume. This was only shown schematically. In reality, it closes on the top of the foot by two flaps provided with loops according to a well known design.
  • a collar 2 On this lower part 1 is articulated a collar 2 by means of two opposite rivets 3 located at the height of the malleolus, that is to say of the natural ankle joint.
  • the collar is also provided with loops, for example loops as shown in patent EP 0286 586, for closing and tightening it around the leg.
  • the collar 2 has, in its upper part 22, an internally ribbed thickening 23, and, in its upper part, a deep notch 4 opening downwards and extending on each side of the shoe, from the region of the 'articulation of the collar approximately halfway up thereof.
  • This notch 4 allows the collar to tilt widely back without coming up against the part 5 of the shell 1 extending around and above the heel.
  • the notch 4 is bordered by a zone of lesser thickness 21 forming a reinforcement in the collar 2, relative to its upper part 22.
  • a plate 7 In the upper part of the zone of lesser thickness 21, above the notch 4, is fixed a plate 7 provided with two stirrups 8 and 9 located one above the other.
  • stirrup 8 is articulated, around an axis 10, a first metal arm 11, the other end of which is articulated by an axis 12 at one of the ends of a second metal arm 13, the other end of which is articulated around an axis 14 on a stirrup 15 fixed to the bottom of the shell 1.
  • the axis 12 common to the two arms 11 and 13 is slidably mounted in a slide 16 formed by two opposite parallel openings cut in a metal U-shaped support 17 fixed on the inside of a cover 18 made of plastic.
  • the cover 18 is in the form of a stirrup articulated on the lower part 1 of the shoe by means of two rivets 20 at two opposite points situated below the articulation 3 of the collar 2.
  • the plate 17 is also also provided with a stirrup 19.
  • the two arms 11 and 13 constitute a toggle.
  • stirrups 9 and 19 engage one in the 'other so as to cling to each other by elastic deformation.
  • the wings of one of the stirrups have, in a known manner, round holes and the other stirrup of bosses which come to engage in the holes of the first stirrup.
  • the cover 18 is thus fixed to the collar 2, but in such a way that it can be detached from the collar by manual traction of moderate force.
  • a certain elasticity in bending can be easily given to the toggle by making one of the arms 11 or 13 in the form of a piston mounted in a cylinder with a spring. Such a construction is indicated in Figure 2 for the arm 13.
  • the axis 12 is at the end of a piston 21 on which acts a spring 22 working in compression.
  • a pivoting of the collar 2 forwards, under the effect of the bending of the leg, has to compress the spring 22.
  • a damping in rear support could be obtained by a second spring placed under the piston 21 or by a spring mounted in the arm 11.
  • the slide 16 could have come in one piece with the cover 18.
  • the cover 18 could be extended towards the top of the collar to facilitate its handling.
  • the cover may be asymmetrical in its upper part.
