Definitions

  • the invention relates to a new plastic ski boot.
  • a modern plastic ski boot essentially comprises: - a shell intended to receive the liner into which the foot is introduced; - a collar, formed in one or two parts, articulated on the shell; - means for closing the collar on the lower leg (buckles, racks, hooks, etc.); - possibly means for clamping the foot in the shell.
  • the invention overcomes these drawbacks. It relates to a ski boot in which, by means of a single tightening member, it is possible to obtain good grip of the foot in all of its parts, namely the lower leg, the heel, the instep and the forefoot, to ensure precise handling of the ski, while allowing easy entry of the foot into the hull. It also relates to a shoe of the type in question in which by a single tightening member, it is ensured sequentially, a tightening of these different parts of the foot in the shell. This clamping member allows, thanks to intermediate positions, easier walking with these shoes, which nevertheless remain held on certain parts of the foot. Finally, it relates to ski boots with rear or mixed entry, having effective rear support, similar to that obtained with shoes with traditional entry.
  • the invention relates to a plastic ski boot which allows, by action on a single member, to obtain a modular and independent tightening, initially of the instep and the forefoot, or even of the heel, while ensuring a pre-tightening of the bottom of the leg, then in a second step of the bottom of the leg.
  • This plastic ski boot which comprises: . a shell intended to receive the skier's foot and which comprises a sole and a rear face, and has a median longitudinal plane; . an articulated collar, intended to enclose the bottom of the leg; . foot holding members in the shell; . clamping members of the collar on the lower leg; . cables for actuating the members for holding the foot and for tightening the collar; . a rigid U-shaped hoop, the two branches of which follow the rear of the shell, cooperates with the members for holding the foot and possibly for tightening the lower leg, and the ends of which are articulated on the shell in the plane longitudinal median thereof; .
  • a U-shaped jumper and gutter whose longitudinal axis is, in the position of use of the shoe, arranged in a direction substantially parallel to that of the tibia of the leg in place in the shell, and whose portion of gutter-shaped connection surrounds the rear of the collar and the bottom of the leg, said jumper also being articulated in the median longitudinal plane of the shell, and cooperating with the tightening members of the bottom of the leg, is characterized in that, under the effect of tilting the rider in the median longitudinal plane of the hull and upwards: -
  • the rigid arch is also driven upwards, until it locks in the high position on the rear face of the shell, to cooperate with the cables which progressively actuate the holding members of the foot in the shell, while the rider cooperates with the cable which actuates the clamping member of the collar to ensure pre-tightening of the lower leg; - then, in a second step, this jumper cooperates with the cable which actuates the clamping member of the collar on the lower leg, to complete the
  • the rigid arch is articulated on an axis crossing the sole in the vicinity of the middle of the latter, and the collar is articulated on the branches of the arch;
  • the collar is, in known manner, made in two parts, respectively a front cuff and a rear cuff, and the front cuff is articulated on the branches of the rigid arch around an axis disposed in front of the passing plumb by the axis of articulation of the rigid arch in the sole;
  • the clamping members are constituted by cables adjustable in tension, in particular by micrometric screws; - two cables actuating the holding member of the foot and a third cable the clamping member of the collar, passes on ramps coming from molding, serving as angle transmission, arranged on the rigid arch, then on pulleys mounted free in the sole, respectively on either side of the median longitudinal plane of the shell, and then above the foot support member, in a housing provided for this purpose, respectively for the first cable at the forefoot, and poir the second cable at the instep, then descend
  • the rear support stop of the hoop on the hull marking the end of the first step (first tightening sequence of foot holding), .
  • a fixed cam is provided on each side at the level of the jumper's hinge pin, to increase the clamping forces, when the assembly is actuated;
  • the rigid arch and the collar form a single piece.
  • This ski boot essentially comprises a shell designated by the general reference (1), a front cuff (2) and a rear cuff (3).
  • the shell (1) has a point (4), two lateral sides (5), a rear (6) with the heel piece and a sole (7). In known manner, this shell has a median longitudinal plane which is not shown, and frequently coincides with the molding joint plane.
  • This shell (1) has on the top, moldings (see Figures 2 and 3) a longitudinal axial slot (10), symmetrical longitudinal slots (8) arranged on each side (5) which, on the one hand, go up on the bottom of the leg (9) and on the other hand, towards the tip (4) provide two transverse slots (11,12) arranged at the level of the toes.
  • the two symmetrical longitudinal slots (8) are connected by a transverse slot (13) disposed at the level of the wedge.
  • This shell (1) is intended to receive a conventional liner in which is inserted the foot of the skier who enters the opening (16) thus formed (see Figures 2 and 11).
  • the rear portion (6) of the shell disposed above the heel has a rigid tongue (17) capable of being pushed towards the tip (4) to ensure by action on the heel pressing the foot against the inner sole of the shell (1).
  • the shoe also includes a rigid hoop designated by the general reference (20) consisting of two branches, respectively (21) and (22), connected together by a connection portion (23) disposed behind the top of the heel (6).
  • the ends of the two free arms (21,22) have circular openings, respectively (24) and (25) intended to be clipped onto complementary cylindrical pins (26) of (24.25), molded and provided for this purpose in the sole (7), to form a hinge pin, designated by the general reference (27), of this rigid hoop (20) in the sole (7 ).
  • the fictitious axis (27) crosses the sole (7) at the level and under the arch.
  • the rigid U-shaped arch (20) follows the rear (6) of the hull and is articulated at (26) around the axis (27) in the median longitudinal plane of the hull.
  • the shoe also includes a rigid rider articulated also in the median longitudinal plane of the shell (see FIGS. 4 and 5).
  • This rigid jumper (30) which acts as an operating member, seen from the side, in the shape of a Z essentially comprises two branches respectively (31) and (32) whose general direction, in the position of use, is substantially parallel to that of the tibia, and which are connected at the top by a connection portion (33) in the shape of a U and a gutter, to marry the bottom of the calf. Almost halfway up, these two rigid branches (31,32) are connected by a second connection portion (34) arranged in the use position, just above the calcaneus.
  • This rigid rider (30) in the form of a Z finally comprises two inclined branches (35) and (36), the lower free ends of which have circular orifices (37, 38) intended to engage on pins provided for this purpose.
  • ears (28,29) coming from molding arranged on the branches (21,22) of the rigid hoop (20) to thereby form a hinge pin (80).
  • the rear cuff (3) is also articulated on this rigid hoop (20) on this same axis (80). In other words, in this embodiment, the axis of articulation of the rider (30) and the rear cuff (3) on the rigid hoop (20) are combined (80).
  • the front cuff (2) is articulated on this same rigid hoop (20) in an axis (39), also arranged on ears which have come from molding, but shown in FIG. 2 so as not to overload it unnecessarily.
  • This axis (39) is disposed above and in front of the plumb passing through the articulation axis (27) of the rigid stirrup (20) in the sole (7) in the direction of the tip (4) .
  • the locking of the stirrup on the top of the rear of the rear cuff (3) is carried out by any known means.
  • the arrangement shown in FIG. 5 is used.
  • the top of the external face (41) of the rear cuff (3) has a lug (42) which cooperates with a bolt (43) which in turn cooperates with a spring (44 ), so that the tip (45) of this bolt (43) traps or releases, as appropriate, the top of the connection portion (33).
  • shell (1) shell (1), front cuff (2), rear cuff (3), rigid hoop (20), rider (30), are made of plastic material in common use for this application with, however different rigidities.
  • the hoop (20) and the rider (30) must be made of a more rigid material than the hull (1).
  • the shell (1) is covered with a cover (19) of suitable shape shown in dotted lines in FIG. 3.
  • the rigid hoop (20) cooperates with three clamping cables (50, 60, 70) which, under the effect of its tilting upwards, that is to say in the direction of the calf, will ensure the tightening respectively of the forefoot, the instep and the bottom of the leg and this, sequentially and independently.
  • the first cable (50) is fixed at its first end (51) in the branch (21) of the rigid arch (20) in the vicinity of the connection portion (23). It passes first on a first ramp (52), coming from molding, also formed on this branch (21), then on a deflection pulley (53) mounted idly in the sole (7), for example on the interior side ( hence the dotted lines) of the shoe.
  • This cable (50) then passes over another ramp (54), coming from molding, formed on the bottom of the sidewall (5) of the shell (1) in front of the axis (27), then rises at an angle on this side (5), passes over the tile (14) where it is held by a guide (17) provided for this purpose, then descends along the opposite side to be fixed at (55) in the sole (7) of the opposite side of (51), i.e. outer side of the shoe.

  • This cable (70) rises upwards to come to bear on a deflection lug (72) fixed on the bottom of the branch (35) of the rigid jumper (30) above the common articulation axis (80 ).
  • these two cables are combined into a single (70) which starts from (76), passes around the pulley (71), rises in (72) and (73), bypasses the top and the front of the front cuff to descend by a symmetrical path on the other side of the shoe, to its fixed point of attachment; a micrometric screw, similar to (75) makes it possible to adjust the length of the two arms of this cable (70) and thereby the tension on the bottom of the leg.
  • connection portion (23) of the rigid arch (20) comprises an adjustable means, such as for example a progressive boss, bearing, in the high position, on the tongue (17 ) from the back of the hull (1) (see Figure 2), to push this tab forward and down, and thereby ensure the heel is held in the hull.
  • adjustable means such as for example a progressive boss, bearing, in the high position, on the tongue (17 ) from the back of the hull (1) (see Figure 2), to push this tab forward and down, and thereby ensure the heel is held in the hull.
  • the rigid hoop (20) and the rider (30), and more specifically the connection portions (23, 34), are secured and disengaged by an articulated rocker device illustrated in FIGS. 6 to 10.
  • rear (6) of the hull (1) cooperates with the L-shaped rocker designated by the general reference (100) which rests on a ramp (101) provided for this purpose on the rear (6) of the hull ( 1).
  • This rocker (100) is fixed by an axis (105) in a clearance (102) provided for this purpose in the connection portion (23) of the rigid arch (20) and passes through a complementary window (110) disposed at its tower and opposite on the lower connection portion (34) of the rigid jumper (30).
  • the L-shaped rocker (100) has two orthogonal branches respectively (103) and (104), articulated around the axis (105) parallel to the plane of the base of the sole (7).
  • the lower part (39) of the jumper In the position of use, the lower part (39) of the jumper, more precisely of the connection portion (34), is always in contact with the branch (104) of the rocker (100), so as to properly hold this rocker ( 100) in this locking position.
  • This rocker locking-unlocking device (100) can be positioned either at the rear in the connection portion (23) as shown in FIG. 6, or on the side or sides of the rear of the hull and in the branches (21,22) of the rigid arch (20) (one or two rockers).
