Definitions
- the invention relates to a new plastic ski boot.
- the single collar or the two cuffs have been articulated on the hull, exclusively around an axis substantially perpendicular to the median plane of the hull.
- the invention relates to a ski boot made of plastic material of the shell and articulated collar type, in which all the degrees of freedom of the leg, ankle and foot are respected.
- the invention consists in hinging the collar relative to the shell in two orthogonal planes, respectively one to allow the movements of the collar forward in a longitudinal plane, the other the movements in the lateral direction in a plane practically orthogonal to the longitudinal plane, and this thanks to an intermediate piece: the rigid stirrup articulated around the shell, preferably at the heel, so that this rigid stirrup is articulated around the rear of the the shell, like a ball joint.
- the boot allows the skier to use in its entirety all the deflections of the leg on the ankle and on the foot, as well in the longitudinal plane as in the lateral plane and all the derived planes, which one does not didn't know how to get in current plastic ski boots.
- Figure 1 illustrates, side view, a first embodiment of the invention of a shoe with a single collar.
- FIG. 2 also shows a side view of another embodiment of the invention suitable for shoes with rear entry (front and rear cuffs).
- Figure 3 shows in longitudinal section the rear of the shoe on the heel side, while Figure 4 is a rear view of this shoe.
- Figure 5 shows an improved embodiment of this rear of the shoe, while Figure 6 shows a section A-A of this embodiment.
- the ski boot comprises a shell (1) of plastic material of common use and hardness for this application.
- This shell (1) comprises a sole (2) and a heel (3) with a rear (4).
- the shoe also includes a single collar (5) ( Figure 1) or two cuffs, respectively front (6) and rear (7) ( Figure 2).
- References (8) and (9) designate known clamping members (8) of the foot in the shell and (9) of the collar on the lower leg, such as loops, racks, etc.
- the shoe comprises a rigid U-shaped stirrup, designated by the general reference (10), for example in molded plastic material, possibly reinforced, or in metal.
- This rigid bracket comprises two lateral branches, respectively (11) and 12), interconnected by a connection portion (13).
- the connection portion (13) of the two lateral branches (11,12) is articulated at (15) on the rear (4) of the shell (1) at the heel, and more precisely at or near the top calcaneus.
- This axis (15) is arranged in a longitudinal plane of the hull.
- the two branches (11,12) see FIG.
- this rigid bracket (10) behaves vis-à-vis the hull (1), and more precisely from the rear of the hull (4), to the like a gimbal element, which allows it to be articulated around the shell and more precisely around an axis arranged inside a longitudinal plane and a plane parallel to the plane of the sole ( 3), in the direction indicated by the arrow F1.
- the articulation axis (15) of the rigid stirrup (10) on the shell (1) is, as already said, situated in the median longitudinal plane and in a horizontal plane with respect to the plane of the sole (3) of the shell (1), passing between the two malleoli (18) respectively internal and external, and at equal distance from these two malleoli.
- the single collar (5) ( Figure 1) or the two cuffs (6,7) ( Figure 2) are articulated at the malleoli (18) on the two branches (11,12 ) of the stirrup (10) on axes or more precisely on lugs coming from molding for this purpose (20,21).
- the axis of articulation defined by the two points of articulation (20,21) is substantially perpendicular to the median plane (P) of the stirrup ( Figure 4).
- the internal face of the free end of these lateral branches (11, 12) has a convex rounded shape, intended to match the concave external shape of the bulges of the malleoli (18) on the shell (1).
- the respective faces facing the stirrup (10) of the shell (1) and the stirrup (10) and the collar (5,6 or 7) are covered with a material with a low coefficient of friction, in particular of polytetrafluoroethylene.
- the collar (5; 6,7) is articulated in the direction indicated by the arrow F2, around an axis perpendicular to the longitudinal plane.
- the characteristic axes (15, 20, 21) can be produced in any known manner: rivets, nipples, pins, etc. .
- the bottom of the lateral flanks of the shell (1) has viscoelastic elements, adjustable in height, intended to limit and dampen the deflections of the legs (11,12) of the stirrup downwards , so the necklace.
- the shoe comprises means making it possible to temporarily block the movements of the stirrup (10) around its axis of articulation (15), for example for the practice of slalom.
- stirrup (10) articulated (F1) around the shell (1) on an axis (15) has in a longitudinal plane, on which is in turn articulated (F2) the collar (5; 6,7), that this set allows the collar to have degrees of freedom in all planes and all inclinations, like the foot and the leg which can move freely around the ankle.
