Definitions
- the present invention relates to a ski boot comprising a first part constituted essentially a sole and an enveloping upper the foot and the malleolar region and a second part consisting of a collar articulated with respect to the rod so as to allow movement of the front collar backwards and vice versa, and means for retaining the collar opposing the tilting of the collar towards the rear but yielding when the effort tending to make tilting the collar exceeds a determined value.
- the purpose of such a construction is to protect the knees of the skier, more specifically the cruciate ligament anterior, when excessive forward force is exerted on the tibia relative to the femur. He was observed that ruptures of the anterior cruciate ligament due to excessive effort of this type have increased in a very large extent while other people's injuries types, especially leg fractures and the ankle have decreased considerably due to progress made in security fasteners. A excessive effort on the anterior cruciate ligament produced in particular during a hump passage, whether either by jumping, at the reception, or by descending quickly the bump.
- the present invention proposes to provide the means much more retaining collar. simple and much less expensive than the devices according to prior art.
- the shoe according to the invention is characterized in that that the retaining means are elastic means bistables consisting of a stop integral with a part shoe and an elastically deformable part attached to the other part of the shoe and intended to be deformed by said stop.
- the elastic piece advantageously consists of a simple curved flexible blade embedded by its ends in one part of the shoe, preferably the necklace, so as to form a piece bistable.
- the stop may have come from molding with the other room.
- the elastically deformable part is constituted by the necklace itself, in which. East formed an oblong cut oriented substantially vertically and having two parts of dimensions at least equal to the dimensions of said stud and connected by a narrowing of width less than the horizontal dimension of the stud, so that it opposes the passage of the stud. In this case, we use therefore the elasticity of the plastic constituting the collar.
- Figure 1 is a partial view, from the back, of the first mode of execution before triggering.
- Figure 2 is a partial side view, of the same mode of execution, in which a snatch allows to see the bistable device.
- Figure 3 is a view similar to Figure 1 showing the bistable device after triggering.
- Figure 4 is a back view of the second mode execution.
- Figure 5 is a side view of the third mode execution.
- the ski boot partially shown in Figures 1 to 3, essentially comprises a shell 1, forming a rod 2 surrounding the foot and the ankle at level of the malleoli and a sole 3, and a collar of lower leg 4 articulated on the shell 1 at the level of malleoli at two opposite points 5.
- the collar 4 is retained against rear tilting by a blade flexible 6, for example steel, curved downwards and retained by its ends in two housings 7 and 8 collar 4 which has a cutout at the back concave 9 extending above the blade 6.
- rod 2 has a bearing surface 10 at middle of which is formed a stop in the form of boss 11 coming into contact with the middle of the blade 6.
- the retaining means are in a first state stable.
- the rod 2 is provided with a stud 12 protruding above of blade 6.
- This stud 12 makes it possible to bring the blade 6 in its first stable state, FIG. 1, by the simple bending of the leg: in the position shown in Figure 3, the blade 6 comes indeed abut against the stud 12 during this bending.
- This embodiment also has the advantage of allow the trigger resistance to be adapted to the user morphology by an adequate choice of the blade 6.
- the back of the rod 2 is provided with an oval stud 13 and the collar has an oblong cutout 14 in which is engaged the stud 13.
- the cutout 14 is oriented substantially vertically and has two parts 15 to 16 of dimensions such that the stud 13 can be there housed in all its angular positions with a low clearance. These two parts 15 and 16 are connected by a narrowing 17 of width less than the most large transverse dimension of the stud 13.
- the stud 13 is provided with a screw slot 18 allowing its rotational drive by means of a piece of change.
- the stud 13 In the descent position, the stud 13 is engaged in the lower part 15 of the cutout 14. It occupies the angular position shown in the drawing.
- the collar 4 is retained in position by the stud 13 which abuts against the narrowing 17. If this effort exceeds the determined value, the pad 13 crosses the narrowing 17 while deforming elastically the plastic of the collar 4. There are trigger.
- the stud 13 could present pairs of facets defining different stud widths. At least two pairs of facets have distances, between facets, greater than the width of the narrowing 15. According to the orientation of the stud, the resistance to its passage to through the narrowing 17 will be more or less high.
- FIG. 5 shows the execution shoe. is fitted with a lower leg collar 19 hinged in 20 behind the rod 2.
- the collar is retained against tilting backwards by a stud 21, similar to stud 13, secured to rod 2, on the side of this rod, and engaged in an oblong cut 22 formed in a plate 23, made of metal or plastic fixed obliquely on the collar 19.
- the cutout 22 present, similar to the cutout 14, two parts 24 and 25 of substantially dimensions equal to those of stud 21 and connected by a narrowing 26 of width less than large dimension of the stud 21.
- the cutting 14 could also be formed in a wafer similar to the wafer 23.
- the cutout 22 could be formed in the plastic of the collar.
