Definitions

  • the present invention relates to a shoe intended to allow the practice of sliding sports such as alpine skiing, surfing, in-line skating, ensuring leg support and the connection between the sliding member and the athlete's foot at the using a shell-type structure and a rigid or semi-rigid rod.
  • the first large family is that of so-called front entry shoes which have a shell provided on the front part with a longitudinal slit, allowing the introduction of the foot and the leg, and whose edges or flaps overlap and are provided with closing and clamping means arranged on either side of the slot.
  • a shell is also called a variable-volume shell due to the possibility of adapting its volume to that of the foot and the leg by action on the closure and tightening means.
  • the foot and the leg are pressed by the flaps of the shell against the sole and the rigid rear part of the shoe.
  • the leg is then said to be referenced towards the rear and it is the rear part of the shoe which defines the angle of inclination of the axis of the leg with respect to the sliding member.
  • the second major family is that of shoes known as rear entry shoes, the shell of which has a rigid and substantially non-deformable front part, known as a constant-volume shell, and a rear cover articulated on the base of the shell and comprising closing and tightening means. on the front part of the hull.
  • the opening of the rear cover allows the introduction of the foot into the shoe from the rear.
  • the leg is pressed by means of the rear cover against the front part of the shell.
  • the leg is then said to be referenced forwards and it is the front part of the shell which defines the angle of inclination of the leg relative to the sliding member.
  • hybrid or “mid” shoes comprising a stem-collar made up of two front and rear covers articulated on a shell base, and which can open "in tulip” for a central entry from the foot to the inside the shoe.
  • blocking means for example of the abutment type, are associated with one of the cowls, generally the rear cowl, to maintain the latter in a determined reference position, the other cowl closing and locking on said cover to enclose the leg.
  • Such a shoe has the advantage of "adapting" by its two parts of the upper to the skier's leg and not the reverse.
  • Such a shoe has never really given satisfaction because it does not allow any satisfactory rear support or referencing.
  • the object of the present invention is to remedy these drawbacks and to provide an improved design of shoe of the shell type offering good referencing for the wearer's leg and a "fixed" advance angle, whatever the morphology of the wearer. , and without requiring the wearer to adapt to the shoe.
  • the shoe according to the invention which is of the type consisting of a shell base capable of receiving the foot of the user and of a rod-collar in two parts articulated on the shell base, and comprising means for reconciling and locking the two parts of the rod in the tightening position of the lower leg, by the fact that it comprises, in combination, means for referencing a first part of the rod relative to the base variable hull depending on the degree of opening / closing of this first rod part, first clamping and locking means associated with said first rod part and controlling the relative movement between said rod part and the shell base, second clamping and locking means associated with the second rod part and controlling the relative movement of the second rod part relative to the first rod part, and by the fact that the clamping and the ve scrambling of the second clamping and locking means and the referencing of the first part of the rod relative to the shell base are controlled by the clamping and locking of the first clamping and locking means, so as to maintain an angle of inclination the axis of the stem-collar substantially constant regardless of
  • the construction envisaged makes it possible to maintain a constant angle of advance whatever the dimensions of the lower leg and in particular of the tibia / calf, since this angle of advance corresponds in fact to the angle of inclination formed by l 'longitudinal axis of the stem-collar, which remains constant.
  • FIG. 1 represents the invention applied to a ski boot 1.
  • This boot 1 essentially consists of a shell base 2, made of rigid synthetic material, and provided on the front with an opening 3 covered by a cover 4 , and on each side of a vertical extension constituting a lateral wing 5, as well as a stem-collar 6 in two parts respectively front 7 and rear 8 each articulated on the shell base according to substantially transverse articulation axes 9 and 10 respectively, and which can be moved towards or away from each other using a common clamping and locking system or tensioning lever 20.
  • the shell base 2 is intended to receive the foot and may comprise, in a manner known per se, an internal clamping system for the foot (not shown in the drawing).
  • This shell base 2 can also be provided with variable volume with a slot, two flaps and clamping / locking means, or on the contrary be of fixed volume as in shoes known as conventional rear entry shoes.
  • the stem-collar 6, 7, 8 is intended for receiving and enclosing the user's lower leg by bringing the two parts of the stem 7, 8 together.
  • the rear rod part 8 is connected to the hull base, in addition to its articulation 10, by an inextensible flexible link or cable 11 anchored at each end, for example by riveting 12, on each of the wings 5 of the hull base.
  • This cable 11 therefore forms a loop, the middle part 13 of which is engaged on a movable nut 21 of the tensioning lever 20 as will be seen below.
  • Each strand of the cable 11 is also guided and returned to the rod part 8 by two slots 14-15 arranged respectively on the side and at the rear of this rod part 8.
  • the cable 11 could also be replaced by two cables each anchored on the shell base and on the movable nut 21 of the tensioning lever 20.
  • the front rod part 7 is connected to the rear rod part 8 by a cable 16 anchored by a rivet 17, or other similar connecting means, on each of the sides of this rod part 7, and the middle part is also engaged on the tensioning lever 20 and its movable nut 21.
  • each strand of the cable 16 is guided and returned to the rod part 8 by two slots 18, 19, arranged respectively on the side and on the rear of this rod part 8.
  • This cable 16 could also be replaced by two cables each anchored on the rod part 7 and on the tensioning lever 20.
  • the tensioning lever 20 essentially consists of a body 22 articulated by means of a transverse axis 23 on the rear of the rear rod part 8.
  • a worm screw 24, connected to an actuating wheel 25 is, in a manner known per se, mounted free in rotation but locked in the axial direction on the body 22 of the lever.
  • This screw 24 carries the nut 21 which, in its own way, is blocked, but axially movable in rotation.
  • a rotation of the screw 24 by means of the wheel 25 causes the displacement along this screw of the nut 21, and consequently the tightening or loosening of the cables 11 and 16 engaged on this nut.
  • the cable 11 is slidably mounted in a semicircular groove 21a of the nut 21.
  • the cable 16 is wound around two semicircular bosses 21b of the nut 21.
  • this cable 16 passes over a semi-circular boss 22a of return provided on the body 22, fixed relative to the nut, of the tensioning lever 20.
  • the reeving of the cable 16 produced using the two bosses 21b of the nut and the boss 22a or fixed point of the body 22 of the lever makes it possible with respect to the cable 11 to double the length of the cable 16 released or as the case may be, tightened when the thumbwheel 25 is actuated.
  • the displacement ratio of the two parts of rods 7 and 8 can be modified and go through example from 2/1 to 3/2.
  • This advance angle " ⁇ " is, as indicated above, defined by the length of cable 11 between the anchor point 12 and the first reference 14. It will suffice to modify the anchor point 12 to obtain angles of advanced " ⁇ " of the entire different rod. This adjustment of the anchor points 12 can be obtained for example and in a manner known per se, by a boss system cooperating with a loop of the cable 11 (not shown in the drawing).
  • the direct connection of the cable 11 to the shell base 2 makes it possible to have very precise referencing of the rear flap part relative to this shell base, and therefore makes it possible to obtain rear support.
  • the referencing of the rear rod part 8, or the rear support, could also be obtained in any other way known per se, for example using an adjustable rear stop cooperating with the rear rod part.
  • shell type that is to say comprising a shell base completely surrounding the base, the main thing being that the shell base comprises the rigid parts necessary for the articulation of the rod parts.
  • joints of the rod parts could also be arranged differently depending on the desired results without departing from the scope of the present invention.
