Definitions

  • the present invention relates to a ski boot shell of the rear opening type comprising a rigid shell bottom, a rod articulated on this shell bottom consisting of a front part and a rear part both articulated and means of closure of this rod put into action automatically by bending the front part of the rod forwards.
  • a shoe of this type is described in the document FR-A-2,540,359.
  • the rear part of the articulated rod hangs, in the open position, tilted back, on a notch of the bottom of the shell, by tensioning a spring.
  • a bending of the front part of the rod has the effect of releasing the rear part which closes on the front part under the effect of the spring.
  • the rear cover is suddenly folded down on the ankle.
  • the automatic closing system does not tighten the rod.
  • the present invention proposes to achieve a softer automatic closure and simultaneously ensuring a tightening of the rod around the leg.
  • the shoe according to the invention is closed by pulling on cables, without a return spring suddenly folding the rear part of the upper.
  • the closure can be done smoothly at the discretion of the user. It is also easy to provide at the rear of the shoe a device for adjusting the final tension of the cables when the traction device arrives in the locked position.
  • a mitten made it possible to solve the problem resulting from the appreciable difference between the possible small displacement of the front part of the rod and the important desired displacement of the posterior part of the rod.
  • the use of a mitten makes it possible to multiply the displacement of the anterior part of the rod.
  • the means for automatic mutual locking of the telescopic parts which are most simply achievable in the form of a pawl are located at the front of the shoe and are therefore easily accessible. It is without other possibility to provide an unlocking by means of a pressure exerted by the end of a ski pole.
  • this elastic element is used simultaneously as an elastic return member for an automatic locking pawl.
  • the shoe shown in Figure 1 is a molded plastic shoe. It consists of a shell bottom 1 made in one piece with the sole 2, on which is articulated around two opposite rivets 3, a rod in two parts, either a front part 4 and a rear part 5. A l inside the shoe is disposed a soft liner 6 whose upper is also split into two parts to be able to open with the upper of the shoe.
  • a cable hooking device 7 for hooking the ends of two cables 22 and 23 passing on each side of the rear part 5 of the rod, in guides, and on each side of the front part 4 of the rod, also in guides, and the other ends of which are attached to a telescopic traction device 8, the ends of which are articulated, of a firstly, in the upper region of the front part 4 of the rod on a stirrup 9 and, secondly, on the bottom of the shell 1, between a pair of projections 10 formed on the bottom of the shell not far from the end of the shoe.
  • the cable hanging device 7 can be produced in the form of a rotary drum allowing the active length of the cables 22 and 23 to be adjusted.
  • the pulling device 8 has the effect of pulling on the cables 22 and 23 when the front part 4 of the rod is bent forward by compressing the telescopic device 8. This pulling device 8 is designed so as to multiply its shortening so as to ensure the closure of the upper of the shoe by the interlocking of its parts 4 and 5 as shown in FIG. 2.
  • the telescopic traction device 8 will be described in detail by means of FIGS. 3 to 5.
  • the female part of the telescopic traction device 8 consists of a substantially rectangular, elongated plate 11 articulated between the projections of the pair 9 and of an elongated rectangular cover 12 U-shaped, positioned on the plate 11, of a firstly by a stud 13 located on a shoulder 30 of the plate 11 and secondly by a pair of lateral tabs 14 of the plate 11 engaging in two notches 15 and 16 of the cover 12.
  • the cover 12 is fixed to the plate 11 by means of a nut 17 screwed to the end of an axis 18 fixed perpendicularly in the plate 11 and carrying a first pair of pulleys 19 and 20 coaxial and of the same diameter.
  • a plate 21 On the axis 18, between the pulleys 19 and 20, is mounted a plate 21 on which is attached the end 22a of the cable 22 and under which is attached the end 23a of the cable 23.
  • two parallel grooves 24 and 25 On the opposite inner faces of the plate 11 and 4 of the cover 12 are formed two parallel grooves 24 and 25 having a first rectilinear part extending parallel to the telescopic device 8, slightly offset with respect to the center line of the device and a curved part 24a, respectively 25a curved in the direction of the other side of its midline.
  • These grooves 24 and 25 serve to house and guide an axis 26 carrying a second pair of pulleys 28 and 29 coaxial and of diameter less than the diameter of the pulleys 19 and 20.
  • the two pairs of pulleys 19, 20 and 28, 29 constitute two mittens, respectively for the cable 22 and for the cable 23.
  • the cable 23 crosses the shoulder 30 on the other side of the latter to pass around the pulley 19, then around the pulley 29 to come and attach by its end 23a to the attachment plate 21.
  • the male part of the telescopic traction device 8 consists of a rectangular metal part pro U-shaped 31 articulated on the stirrup 10.
  • One of the sides of this part 31 has an edge 32 folded parallel to the plate 11.
  • the width of this folded edge 32 is such that it lets the axis 18 of the pulleys 19 and 20 pass freely, but that it abuts at its end 33 against the axis 26 of the pulleys 28 and 29 when this axis 26 is in the rectilinear part of the grooves 24 and 25.
  • the bent edge 32 therefore extends between the grooves 24 and 25, in their rectilinear parts, but only in this rectilinear part, so that when the axis 26 of the pulleys 28 and 29 engage in the curved parts 24a and 25a of the grooves, the pulleys 28 and 29 escape the end 33 and that the bent flange 32 can pass next to the pulleys 28 and 29.
  • the flange 32 has a notch 36 serving as a limit stop for travel to the axis 18, that is to say ie the extension of the traction device.
  • the other side of the male part 31 also has a flange 34 bent parallel to the plate 11, but it extends longitudinally less far than the edge 32, so that its end 35 does not interfere with the movement of the pulleys 28 and 29 in the curved parts 24a and 25a of the grooves 24 and 25.
  • the length of the edge 34 is however sufficient to ensure satisfactory guidance of the two telescopic parts in one another. Over a certain length, the edges 32 and 34 form two parallel arms between which there remains a space for the passage of the axis 18 pulleys 19 and 20. A corresponding slot is provided on the bottom of the part 31.
  • a pawl 39 extending parallel to the axis of the telescopic traction device and on the elastic block 37 which also serves as spring for the pawl 39.
  • the pawl 39 has a bent lower end against which the elastic block 37 bears, which thus also keeps the pawl 39 in the working position.
  • the pawl 39 is provided with two nozzles 40 and 41 intended to cooperate with two notches 42 and 43 formed by the ends of two parallel longitudinal grooves 44 and 45 formed in the inner face of the cover 12 of the female part.
  • the pawl 39 can be raised to the position 39 ⁇ shown in phantom, for the establishment of the block of elastic material 37 or to replace this block, for example with a block of different hardness.
  • the end 33 of the longest arm of the male part 31 pushes back the axis of the pulleys 28 and 29 along the rectilinear part grooves 24 and 25, so that the two sets of pulleys move away from each other.
  • the distance from which the two sets of pulleys deviate results in a shortening of the cables 22 and 23 equal to twice the said distance, which has the effect of ensuring rapid closure of the two parts. 4 and 5 of the upper of the shoe.
  • the initial length of the cables and the shortening is chosen so that the upper of the boot is tightened around the ankle of the skier.
  • this axis 26 engages in the parts curves 24a and 25a of the grooves and escapes at the end 33.
  • the male part 31 can continue its penetration into the female part 11, 12 without further modifying the spacing of the two sets of pulleys, that is to say without increasing tightening the upper of the shoe.
  • the pulleys 19 and 20 abut against the block of elastic material 37 by compressing it slightly and the spouts 40 and 41 of the pawl 39 come to hang behind the notches 42 and 43 of the female part.
  • the traction device 8 is then locked in the closed position for skiing.
  • the block of elastic material 37 acts as an elastic stop ensuring the elasticity of the upper of the shoe to flexion.
  • the telescopic device 8 is susceptible of numerous variant embodiments.
  • the stop 33 could act directly on the shaft 26, passing between the pulleys 28 and 29, so as to reduce the braking action on the pulleys.
  • the pulley sets could include more than two pulleys if it were necessary to increase the multiplication of the telescopic device stroke.
  • the curved parts 24a and 25a of the grooves could be simply oblique rectilinear.
  • the two cables could be replaced by a single cable.
  • the pawl 39 could be mounted on the other telescopic part. It could be replaced, for example, by two lateral pawls.
