Definitions
- the present invention relates to a device for supporting a ski boot on a ski.
- a modern ski safety binding composed of a front stop and a heel, is equipped with a device for supporting the boot, and more precisely the sole of the boot, on the ski.
- This device comprises a sliding plate which is associated or integrated with the front stop and is intended to serve as a support for a smooth area, of location and of standardized dimensions, which is provided under the front part of the sole.
- This plate is lined with a material with a low coefficient of friction, for example PTFE (polytetrafluoroethylene).
- PTFE polytetrafluoroethylene
- a device of this kind which is described for example in document FR-A-2 150 314, generally gives satisfaction under the usual conditions of use.
- Document DE-A-2 333 166 relates to a device of this type.
- This device comprises a base plate which is fixed on the ski, on which is articulated a plate which can pivot laterally in a plane parallel to the ski, this on one side or the other.
- the insert has a disc-shaped backing pad which can rotate about its own axis relative to the insert.
- the plate is returned to its normal position centered on the ski by means of a hairpin-shaped spring, that is to say made up of a curved spring wire in the shape of a "U” or " V ".
- This known device has the advantage of using a return spring that is both robust, reliable and compact.
- French patent application n ° 89 12761 filed on November 29, 1989 in the name of the applicant, and not yet published on the date of filing of this application, relates to a support device which comprises a base plate carrying a plate laterally movable support.
- the plate is returned to the central position by a torsion spring in the form of a hairpin, the ends of which engage in a transverse slot which is formed in the brochure; guide means are provided which allow the wafer to follow in firstly, a transverse displacement stroke in pure transla ⁇ tion, then, beyond a certain transverse stroke, a tilting of small amplitude in a plane parallel to the ski.
- This device has the advantage of being simple and compact, and of using a support plate whose shape corresponds to the standardized support zone provided under the shoe.
- the tip tilting stroke is necessarily very limited to prevent the ends of the "V" branches of the hairpin spring from unexpectedly escaping from the transverse slot, which would prevent re-centering. subsequent automatic wafer.
- the present invention aims to improve this device by providing it with means which allow - beyond the initial stroke of purely transverse movement - a relatively large tilting of the plate in a plane parallel to the ski, these means further achieving the control of said tilting movement while ensuring with certainty the subsequent automatic refocusing of the movable plate.
- the device which is the subject of the invention is a device of the kind which has just been mentioned, which comprises a return spring having the shape of a hairpin whose two branches extend symmetrically with respect to the axis longitudinal of the ski; according to the invention, each of these branches is provided, at its free end, with a guide piece which engages in a profiled counterbore formed in the underside of the plate, so that the cooperation of this counterbore with the guide parts makes it possible to limit the amplitude of clearance of the plate and to control the tilting movement thereof , in one direction as in the other, then bring the plate back to its central position.
- the guide parts are small plastic blocks which are overmolded on the ends of the branches of the spring, these parts advantageously resting on their underside in a closed curved groove which is formed in the base plate.
- the block-shaped guide parts are in support (apart from play) by their external edges both against the lateral edges of the counterbore and against the ends of the groove.
- the support plate has, when viewed from above, a general rectan ⁇ gular shape (which corresponds substantially to the shape of the standardized sliding zone provided under the sole of the shoe).
- the long sides of the rectangle extend transversely to the ski, each of these long sides having a thin part in the shape of a tenon which cooperates with a tongue integral with the base plate, so as to ensure the retention of the plate on the plate based.
- the tongue located on the spring side forms an integral part of a cover which is attached and fixed, for example by snap-fastening, on the base plate, this cover recou ⁇ vrant the return spring.
- the spring in the form of a hairpin is advantageously housed in a recess whose shape is complementary to that of the spring ("V" shape), this recess being hollowed out in the base plate and constituting a clearance space into which a corner part of the insert can penetrate during its tilting.
- the edge of the thin part forming a tenon has a central part which acts as a support zone for the tilting of the plate relative to the base plate, this central part being bordered by two notches which also constitute clearance spaces.
- the spring it is possible to provide for the spring to be housed in the base plate under a slight prestress (branch slightly tightened relative to the normal state of the spring) so that lateral movement of the plate is only possible if the transverse force exerted by the sole on the plate exceeds a certain threshold; there is therefore a "hard point" which prevents any play in the movable plate during periods of non-use of the binding.
- FIG. 1 is an exploded perspective view, partially broken away, of all the elements of a device according to the invention
- FIG. 2 is a partial view, cut by a vertical longitudinal plane of a part of the device - in this case of the part comprising the movable plate -;
- FIG. 3 are top views diagram ⁇ ticks cut by the plane 111-111 of Figure 2, on a smaller scale than that of this figure, of the device, these figures showing three successive positions of the wafer during its lateral release movement;
- FIG. 7 is a schematic top view, on a larger scale, intended to show the shape of the guide piece which is provided with a branch of the spring.
- the device shown in the figures comprises a base plate 1 of plastic with high mechanical strength obtained in one piece by molding.
- the plate 1 comprises a relatively thick part 10 intended to be directed towards the rear of the ski (not shown) and a thinner part 11 intended to be turned towards the front.
- the width of the plate 1 corresponds substantially to the width of the ski.
- In the thin part 11 are provided holes 110 for the passage of screws for fixing the front stop on the ski; the plate 1 is therefore fixed to the ski at the same time as the front stop (not shown). From back to front, plate 1 has:
- transverse tongue 14 which defines a vertical bottom groove 140
- film 5 made of a material with a low coefficient of friction, for example PTFE, which is bonded to the upper face of the part 10;
- Part 15 in the form of a plate which comes in excess thickness on the upper face of the base plate 1.
- Part 15 has the general shape of a "V", the opening of which is directed towards the rear and which is arranged symmetrically with respect to the longitudinal axis XX 'of the plate 1, an axis which corresponds after mounting to the longitudinal axis of the ski.
- the side branches of the "V" portion 15 have been designated by the reference 16 and by the reference 17 the interior edges of the portions 16. These edges define an interior space (recess) referenced 170.
- the ends of the portions 16 are shaped into parts 18 facing outwards, whose rear edges, of small width, are referenced 19.
- a cylindrical stud 100 At the top of the "V" clearance 170 is arranged a cylindrical stud 100, centered on the axis XX ', and the height of which corresponds to that of the part 15.
- the curved groove 13 is a closed groove, the edges 130 of which stop a little before the lateral edges of the plate 1.
- the front part 12 of the thin part 11 has an advantageously rounded shape, which corresponds to the front contour of the plate of the front stop.
- the mobile support plate has been designated by reference 2.
- This plate has a body 20 of high-strength plastic obtained by molding.
- the body 20 has a rectangular shape adapted to be engaged laterally, in the manner of a drawer, on the base plate 1 between the groove 140 and the edge areas 19. After engagement, it therefore rests on the film. 5, in good conditions to slide laterally.
- the underside of the body 20 is a flat face while the top of this body is an arcuate face 26 in which is embedded and bonded a lining 6 made of a material with a low coefficient of friction, for example PTFE. It's this lining which is intended to serve as a support for the standardized sliding zone provided under the sole of the shoe.
- the body 20 On its two long sides (sides arranged transversely to the axis XX) the body 20 has thin parts, or tongues, 22, 27 playing the role of tenons.
- the tongue 27 which is directed towards the front of the ski has a straight edge 28; on the contrary, the tongue 22 facing the rear of the ski has a cut contour comprising a straight central part 24, of short length, as well as two lateral parts 23 also straight and of short length; the part 24 is connected to each of the lateral parts 23 by curved portions conca ⁇ ves, which define notches 25.
- the rear tenon 22 is overhung by the rear edge of the upper wall of the body 20 so that the parts 21, 22 define a complementary groove of the tongue 14 of the base plate.
- the return spring of the plate 2 has been designated by the reference 3.
- This spring has the general shape of a hairpin; it is formed in a spring steel wire wound on itself to form a few helical turns 33 and having two divergent branches 31 which give it the general appearance of a "V".
- the ends 32 of the branches 31 are slightly bent towards the outside, and carry guide pieces 9.
- the latter are small pavers of plastic material which are attached by overmolding on the ends of the parts 32, these ends having preferably been previously crushed to improve the quality of the retention of the parts 9 on the spring and in particular to avoid their rotation relative to the wire.
- the part 33 is shaped to fit onto the cylindrical stud 100.
- the spring 3 when the spring 3 is in its natural state, its two branches 31 form an angle (acute) which is slightly larger than the angle of convergence of the walls 17 of the clearance space 170.
- this natural state of the spring has been illustrated, by representing one of its branches, referenced 31 ′, in dashed dashed lines, the associated guide part being designated 9 '.
- the spring 3 is shaped in such a way that it can be placed in the space 170, the parts 9 then coming to be placed in the curved groove 13, bearing against the edges 130 of this groove.
- the device also comprises a part 4 forming a cover which comprises a main body 40 whose rear edge 43 has the shape of a transverse tongue.
- the part 4 On its underside, the part 4 carries a pair of hooks 42 in the shape of an inverted "L". These hooks are located on the two lateral edges of the part 4, near the tongue 43; they have their free branch directed inward and are adapted to engage in complementary recesses formed on the sides of the parts 18 of the base plate 1. Similarly, the front edge of the part 4 has a part forming a hook, of section in the shape of an inverted "L", the branch of which is directed towards the rear. This part 41 is intended to come into engagement with the thinned edge 150 of the front wall of the part 15.
- this counterbore opens out towards the front of the skiing; it has an outline, most of which 82 has the general shape of an arc of a circle, similar to the shape of the groove 13, the center of curvature of which is directed towards the front of the ski and is centered on the axis of longitudinal symmetry XX '.
- the portion 82 is connected on each side to a straight portion 81 which diverges slightly towards 10
- portion 81 se. connects to another portion 80 which converges towards the axis XX to open out on the front side of the plate (see FIG. 6).
- the sum of the depths of the groove 13 on the one hand and the counterbore 8 on the other hand is very slightly greater than the thickness js of the guide blocks 9.
- the assembly of the various constituent elements of the device is done as follows.
- the spring 3 is firstly put in place on the plate 1, after slight tightening of the branches 31, so that the winding 33 comes to cover the stud 100, and the branches 31 come to be placed near the walls 17 of the clearance space 170.
- the guide pieces 9 come to bear against the edges 130 of the groove 13.
- the plate 2 is then placed on the plate 1 so that the tenon 22 is inserted into the groove 140 and that the counterbore 8 is placed on the pieces 9. The latter are therefore trapped between the bottom of the groove 13 and the bottom of the counterbore 8.
- the counterbore 8 is profiled and dime ⁇ sion ⁇ é, and the plates
- each of the parts 9 are shaped, so that in the rest position each of the parts 9 is supported both against the groove edge 130 by a first facet 91 and against the counterbore portion 81 by a second facet 90, as is shown in Figure 6.
- a reverse arrangement is naturally also possible, the slight clearance being in this case provided between the facets 91 and the edges 130, while the facets 90 are applied against the counterbore portions 80.
- the cover 4 is then put in place by sliding it. on the part 15 in a longitudinal movement directed from the front to the rear of the ski so that the hooks 41 on the one hand and 42 on the other hand snap onto the parts 150, respectively 18.
- this mounted assembly is fixed to the ski at the same time as the front stop.
- the ski boot will rest on the lining 6 of the pad 2.
- the slightly domed shape of this lining permanently ensures its correct contact with the underside of the sole, even in the event of irregular wear. of the latter, in the event of the boot tilting forward during skiing, or during a multidirectional fall, in particular in pre-torsional fall.
- this force is transmitted by the boot to the front stop which is moved laterally, in one direction or the other, against the elastic return system which the team, and whose hardness has been preset according to certain characteristics specific to the skier.
- the other branch 31b remains in contact via the part 9b against the corresponding end of the groove 13.
- the plate is guided at its four angles because the rear edge regions 23 of the plate bear against the groove 140 of the base plate and the edge 28 of the front tongue 27 is facing with respect to the vertical support zones 19 of the lateral parts 18 of the base plate.
- the plate 2 therefore follows a purely transverse trajectory. Beyond a stroke referenced ⁇ in Figure 4, the zones 19 no longer provide guiding in translation of the wafer.
- the plate 2 is shown in a position offset laterally by a stroke j_ pa r relative to the longitudinal axis XX 1 .
- the movable plate can also tilt and move back, in order to accompany the shoe as faithfully as possible and avoid relative slippage between the sole and the lining 6.
- Tipping is possible due to the fact that the corner part of the pad which has arrived in the central region of the ski is located opposite the clearance space 170, inside which it can engage freely, and partially. However, this tilting is controlled by the fact that the guide piece 9a is constantly trapped inside the counterbore 8, in contact against the edge of this counterbore. Note in Figure 6 that the rear edge of each plate 9 has one. rounded area 92 capable of both sliding against this rim and serving as a tilting area for the insert.
- the edge region 24 of the tongue 22 serves as a fulcrum for tilting the plate against the groove bottom 140, while the clearances 25 located on either side of this zone 24 effectively authorizes this tilting.
- the spring branch 31a automatically brings the movable plate back to its central position on the ski.
- the movable plate is kept centered on the ski without significant play even in periods of non-use, especially when the skier carries the skis before putting them on. put on or after heaving.
