Description

The present invention relates to an assembly device, no-

  especially for fixing a ski boot to a ski, with coupling parts of a coupling device which, by means of a bearing assembly, are fixed, in particular in an adjustable manner, in a transverse plane oriented substantially obliquely or perpendicularly to the longitudinal direction

  from the ski, and at a preset distance from the ends of the ski.

  Various assembly devices are already known for fixing

  and assemble ski boots to skis According to the European patent

  péen EP-104 185, such an assembly device is produced in the form of a ski binding, and it comprises as coupling device a front jaw and a rear jaw or a heel clamp In order to obtain a better shock absorption and vibration undergone by the ski, the front jaw and the heel clamp are arranged on a rigid support element in flexion This support element is rigidly screwed at one end of the ski, while at the opposite end of the supporting element in the longitudinal direction of the ski, the screws

  are guided in oblong holes extending parallel to the

  in the longitudinal direction of the ski We thus obtain a long mobility

  gitudinal of the front part of the ski with respect to the rigid carrying element in bending In order to therefore absorb shock and vibration, a respective elastic damping element is disposed between the fixing means and the front regions of the oblong orifices which are located on either side of these fixing means. The longitudinal movements between the ski and the carrier element are thus damped.

  rigid in flexion, which are triggered by a deformation of the ski

  tically on its sliding face We have thus been able to somewhat reduce the shocks and vibrations undergone by the ski user. The use of a rigid bending support element makes it possible to obtain that independently of the elastic deformation of the ski, the distance between the front jaw and the rear jaw, or the angular position between the

  contact face of the ski boot and the contact face of the ski

  front and rear jaw, always extends so

  parallel on the ski surface But the downside is that it

  undesirably undermines the elasticity of the ski.

  According to the ski binding of the firm ESS, equipped with the va r system, an assembly device is also known in which the differences between the arc length of the deformed ski and the distance between the front jaw and the rear jaw which is determined by the length of the rope, differences which appear during the elastic deformation of the ski following stresses perpendicular to the sliding face, are compensated for by the fact that the rear jaw is mounted, with the possibility of adjustment in the longitudinal direction of the ski, in a longitudinal adjustment device fixed on the ski, and

  is assembled in displacement in the longitudinal direction of the ski to the hand

  front choir, via a tightening band.

  The use of the longitudinal adjustment device makes it possible to obtain longitudinal compensation between the ski which deforms in an arc and

  the sole of the ski boot which forms a rope, in their

  front and rear jaws with longitudinal spacing

  fixed by the shoe The clamping forces required between the shoe

  front choir and rear jaw are exerted via the tightening band When coupling the ski boot and the ski, and following this coupling, the tightening band fixes the distance between the front jaw and the rear jaw, and it simultaneously fixes the distance between the rear jaw and the point

  for fixing the front jaw The front jaw and the rear jaw

  here are fixed on the ski, and their contact faces turned

  towards the ski surface take, during deformations of the ski perpendicular

  cularily on its surface, different angular positions relative to the contact face of the ski boot, so that undesirable tensions still occur between the front jaw, the

  rear jaw and ski boot.

  Another assembly device, known from patent AT-302,103, consists of a sole plate for the coupling parts of the coupling device, that is to say the jaw

  front and rear jaw of a ski binding

  is assembled to the ski in the region of its two ends At one end, the plate is rigidly fixed, or pivotally mounted by

  through an axis perpendicular to the longitudinal direction of the ski.

  At the other end, the sole plate is prevented from coming off, and guided in the longitudinal direction of the ski. Certainly, one thus obtains a possibility of relatively free movement of the ski compared to the

  coupling device consisting of the front jaw and the jaw

  rear choir, but we need an independent soleplate for fixing the coupling device on the ski, which separates the sole of the boot even more from the surface of the ski which is

facing this sole.

  The object of the present invention is to allow free deformation

  tion of the ski in the region of the coupling device and a posi-

  predefined relative tion between the ski boot and the parts

  coupling device, even in the presence of

variable ski training.

  According to the invention, this object is achieved by the fact that each of the coupling parts is fixed to the ski by means of an approximately elastically deformable bearing assembly.

  perpendicular to the longitudinal direction of the ski and at least perpendi-

  The main advantage of this solution

  inventive tion is to prevent possible convergence between the coupling device and the ski boot, for example between

  a front jaw and a rear jaw, by a deformation curve

  harmonious tion of the bearing assembly both in the region of the

  choire before that in the region of the rear jaw, that is to say of the two coupling parts of the coupling device, and that in the presence of variable deformations of the ski, the forces of release of the

  coupling device, which is for example an automatic fixing

  ski tick, are not changed Simultaneously, it is guaranteed in the region of the coupling device better support of the face of

  ski slips in the presence of various deformations, in particular of

  brations in the front or rear region of the ski, as well as

  which is set up simultaneously with the deformation, deflection movements or relative movement-movements between

  ski and ski boot This application on a large sur-

  face of the sliding face of the ski allows it to face the conditions

  a wide variety of canvassing and skiing conditions with

  low ground clearance, which eliminates the risk of the ski sinking and

  the related braking and deceleration forces This allows, no-

  especially in the field of competition, to obtain a higher speed in curve and a finer control of the changes of direction For the skiers who do not make competition, one obtains the advantage that the force to exert for the changes of direction is weaker thanks to the reduced ground pressure, and therefore that the ski turns more easily The force to be exerted to initiate turns, whether it is competition or leisure skiing, is thus improved.

  surprisingly simple, initially unpredictable If-

  simultaneously, the track behavior and consequently the safety of skiing are improved, because the differences in ground pressure and the

  acceleration and deceleration by jerks which are linked to it are re-

  We obtain in particular a harmonious tension curve and a regular distribution of the rigidity over the length of the ski, because

  that the deformation movement of the ski is no longer blocked by the provision

  coupling coupling which holds the ski boot This also provides an improved edge attack over the entire length of the

  edges To this is added advantageously that the tension curve har-

  monieuse, and therefore the qualities sought by ski manufacturers, are respected in the most diverse conditions of skiing and

  solicitation, since they are no longer adversely affected

  created by the coupling device, i.e. by fixing and

  by ski boots held by the binding.

  According to an additional configuration, it is expected that

  the bearing assembly comprises two elastically deformed bearing bodies

  formables, which are arranged in mutually transverse planes

  distant in the longitudinal direction of the ski, so that the region

  tielle of the ski which is stiffened by the bearing assembly can

  extend over a reduced and short distance.

  It is also advantageous for the elastically deformable bearing body to comprise an elastically deformable body, for example a

  rubber block or plate, placed between two mounting plates

  floor, and that a mounting plate is assembled while traveling on the ski

  by means of fixing, and that the other is sufficiently-

  locked in movement to the coupling part of the coupling device by means of fixing means. It is thus possible to obtain a quick and precise mounting of the bearing assembly on the ski, and a very solid fixing, with a few points. fixing, between the bearing assembly and the coupling device, in particular

  the front or rear jaw of a ski binding.

  It is also possible that the mounting plate includes housings for several means of fixing the coupling part of the coupling device, so that support can be obtained at several points and a rigid fixing in rotation and in torsion coupling parts on the bearing assembly. According to another additional configuration, provision is made for the mounting plate to be provided with several similar housings, but mutually in the longitudinal direction of the ski, for fixing means, since it is thus possible to obtain variable positions of the parts.

  coupling, i.e. the front or rear jaw of the device

  coupling device, which makes it easy to adapt the mounting position of the coupling parts to different sizes of

  ski, and in particular to different sizes of ski boots.

  It is also advantageous that the bearing body is made up of

  killed by an elastically deformable block of rubber and / or material

  plastic, because we can thus obtain in a simple way a low resistance during relative displacements between the parts

  coupling and skiing, accompanied by a damping of the movements-

diversions.

  The plastic and / or rubber block can also be reinforced, in particular by carbon fiber wires or metallic intermediate layers. Thanks to this additional reinforcement by suitably configured inserts, it is possible, with

  housing of bearings of small section or volume, transmit in a ma-

  correct and reliable, without deterioration of the bearing housings, the high peak stresses which appear, especially for

  ski bindings, between the ski and the coupling parts.

  The two mounting plates can also be guided in

  a guide rail, in a direction parallel to the long direction

  tudinal of the ski and perpendicular to the ski surface This slide allows a precise transmission of the control forces in the direction perpendicular to the longitudinal direction of the ski, and especially of the corresponding forces of pressure of the edges, since from a

  certain value of the relative displacement in perpendicular directions

  laires in the longitudinal direction of the ski, direct force transmission

  the boot on the ski is guaranteed.

  According to another additional configuration, provision is made for the mounting plates to be made in a U-shape, the branches of the U-shaped mounting plates being turned towards one another, and a free width between the branches of a plate. mounting corresponding approximately to an outside width between the mutually opposite sides of the two legs of the other mounting plate, and

  that a thickness of the elastically deformable bearing body corresponds to

  lays, in the unsolicited state, at a length of the branches of a

  first mounting plate, plus part of the length of the branches of the second mounting plate, so that guidance is obtained

  precise lateral between the boot and the ski over the entire elas-

  tick possible between shoe and ski.

  According to an advantageous embodiment, the mounting plate opposite the ski is formed by a base plate which receives so

  adjustable housing of the coupling part Such an embodiment

  sation allows in a simple way, by the association of a body of

  elastically deformable bearing, to continue to use without the

  to define conventional fasteners, while obtaining the advantages

brought by this configuration.

  According to an additional configuration, a base plate of the coupling part is assembled by means of a device

  adjustment to the mounting plate of the bearing assembly which is op-

  placed on the ski, so that no modification of known and marketed bindings is necessary to obtain the advantages provided

  by the elastically deformable bearing body.

  According to another additional configuration, the coupling parts of the bearing assembly which are mutually distant in the longitudinal direction of the ski, in particular the front jaw and the rear jaw of a ski binding, are assembled in displacement by the intermediate a spacer, in particular a traction strip Thanks to this spacer, the bearing assemblies and in particular their elastically deformable bearing bodies are not stressed by the preload forces which are necessary

  between the coupling parts, in particular the front jaw and the

  rear choir of a ski binding, so that the entire deformation stroke and the bearing capacity of the bearing housings

  are available for deformations between the boot and the ski.

  It is also advantageous if the traction strip is assembled

  hinged in an articulated manner to the mounting plate via an axis approximately perpendicular to the base plate Thanks to the articulated assembly between the spacer element and the mounting plate or the bearing assembly, the coupling parts of the coupling device can adjust and center themselves when the ski boot is placed in the coupling device, so that unnecessary deformation between the coupling parts of the coupling device and the shoe

ski.

  According to an alternative embodiment, the traction strip is

  made of a material, in particular a metallic strip, which is

  extensible but nevertheless flexible perpendicular to the plate

  mounting, so that this strip can follow possible deformation

  the sole of the ski boot in perpetual directions

  dicular on the surface of the ski, and that one can thus obtain a damping

  additional shock between the two coupling parts

  of the coupling device, in particular the front jaw and the jaw

  rear choir of a ski binding.

  According to another alternative embodiment, it is expected that the

  mounting plate which faces the ski is mounted in sliding

  sement in a longitudinal guide fixed on the ski, which reduces the deformation strokes that can be received by the elastically deformable bearing body, and therefore the stresses of the latter, without limiting the possibility of free movement

  of the ski in relation to the coupling device or even to the boot

  In addition, such an arrangement allows easy adaptation to

different shoe sizes.

  It is also advantageous that the guide rail for the mounting plate of the bearing assembly which faces the ski

  either elastically deformable in a direction perpendicular to the sur-

  face of the ski, because thus, despite the possibility of free movement of the bearing assembly in the longitudinal direction relative to the ski,

  does not stiffen the ski over a distance extending

  beyond the length of the bearing assembly in the longitudinal direction

ski.

  According to another alternative embodiment, the length of

  the spacer element is adjustable.

  tion simplified to different shoe sizes, the modifications of the length of the spacer can be effected by a different deformation of the elastically deformable bearing bodies in the longitudinal direction of the ski, or by the possibility of adjustment

  longitudinal, described above, of the bearing assembly.

  The mounting plate can also be provided with several hous-

  elements for a pin of the joint articulated between the strip

  assembly plate and mounting plate, which provides a

  additional information for the distance between the parts of the

  mating, by arranging the pins in different housings-

the mounting plates.

  According to another additional configuration, it is provided that the mounting plate which faces the ski has a face, parallel to the surface of the ski, smaller than the mounting plate

  associated with the coupling parts, which guarantees sufficient fixing

  securely stable of the coupling part on the mounting plate, while keeping the stiffness exerted on the ski by the

  mounting plate facing the ski.

  The mounting plate which faces the ski can also consist of several plate parts which are mutually

  assembled, or mutually discarded by being for example respective-

  independently assembled to the bearing housing, by means of weakening zones and / or articulation points oriented perpendicularly to the ski but parallel to the ski surface. This effectively prevents stiffening of the ski, even if Rather long mounting plates are assembled to the ski. It is also advantageous that a base plate or a bearing plate of a coupling part, for example of the front jaw of the coupling device, is fixed at a distance from the surface of the ski by means of several sets of bearings distributed over the surface of the ski, and which each of these sets of bearings has

  a mounting plate associated with the ski and the base plate or

  link, and an elastically deformable bearing body disposed between them The use of several sets of bearings makes it possible to obtain a punctual support of the part of the coupling device on the ski and consequently a minimal stiffening effect, as well as a montage

  statically defined of the coupling part.

  According to another additional configuration, provision is made for a base plate and / or a mounting plate and / or a bearing plate to be assembled in displacement with the body or the bearing bodies, in particular with the block, of elastically deformable material, the bodies of

  bearings being fixed on the ski by means of mounting plates

  preferably mutually independent, so that the number of parts can be advantageously reduced, while nevertheless obtaining a statically defined attachment of the coupling parts to the ski. According to an advantageous embodiment, the bearing body

  or the block of elastically deformable material, rubber or elasto

  mother in particular, is assembled by means of a layer of glue to the base, bearing and / or mounting plates The use of an independent layer of glue makes it possible to carry out just before mounting

  the assembly between the bearing body or the block of elastic material

  only deformable and the mounting or base plates and / or pa-

link associated with it.

  The bearing housing or the block of elastically deformed material

  mable can also be assembled to the mounting, base or bearing plate during the manufacturing process, in particular the foaming or injection process, so that an intimate assembly is obtained

  and durable between the mounting plate and the bearing housing.

  Finally, it is also advantageous if the bearing body or the

  block is vulcanized on the mounting or base or bearing plate.

  Vulcanization makes it possible to directly assemble the bearing body or

  the elastically deformable block to any element of a device

  assembly sitive, and in particular to its base plate, so that one can do without an additional mounting plate as well as other high-strength assembly means between the plate

  base and such a mounting plate.

  This assembly device 3 comprises a coupling device which

  consists of several coupling parts, in particular a

  front chock 4 and rear jaw 5.

  The front jaw 4 consists of a housing 6 in which a sole support 7 is adjustably mounted against the action of a release spring 8 which, for a front jaw designed as a safety attachment, determines release force A

  following the loosening of a stop device consisting of a

  rillon 9, the housing 6 is slidably mounted relative to a base plate 10 in the longitudinal direction of the ski 1 In addition, a spacer 12 for the sole support 7 is fixed to the jaw there

  front 4, preferably on a pivot 11, element which extends parallel-

  lying in the longitudinal direction (arrow 13) of the ski 1 and which is assembled in displacement with a housing 15 of the rear jaw 5, by

  through an adjustment device 14 The housing 15 of the

  rear choir 5 also houses a sole support 7 which maintains a sole 16 of the ski boot in position relative to the ski 1 This tight position of the sole support, keeping the sole 16 in the schematically represented position, can be released at

  using an actuating lever 17 or, in the event of ex-

  cessive, by the action of the release spring 8 The force which must be exerted by the ski boot 2 on the sole support 7 to produce a release of the boot, can be adjusted to

using an adjustment screw 18.

  So that the ski boot is tight without play between the supports

  sole ports 7 of the front jaw 4 and the rear jaw 5, (tensioning preload springs 19 are arranged in the housing 15, the pressure force of which can be preset and through which the housing 15 is pressed the adjustment device 14, which is here, for example, an adjustment worm This adjustment device 14 makes it possible to adjust both the distance between the front jaw 4

  and the rear jaw 5, in order to adapt to different lengths

  the sole of the ski boot 2, that the force of

  prestressing exerted by the prestressing springs 19 The provision

  coupling coupling, consisting of the front jaw 4, the rear jaw 5 and the spacer 12, together with the ski boot 2 constitutes a closed and autonomous force system, which

  does not exert support or clamping forces on the ski 1.

  The front jaw 4 and the rear jaw 5 are fixed to the ski 1 by means of sets of bearings 20.21 Each of these

  bearing sets consists of a 22.23 turn mounting plate

  born towards ski 1 and a mounting plate 24.25 associated with the

  front or rear choir 4.5 bearing bodies 26 are arranged between the mounting plates 22, 24 and 23.25 these bearing bodies 26 are formed by a block 27 or an insert in the form of a plate of elastically deformable material, in particular an elastomer, a soft synthetic foam or rubber, optionally mixed with corresponding plastics The bearing bodies 26 or their blocks 27 can be formed by injection or foaming on the mounting plates 22,24 or as the case may be 23,25, or be injected or foamed

  between these plates, or else be assembled to one of the two plates by one of the aforementioned processes, and to the other mounting plate by a pro-

  vulcanization stop or a layer of adhesive 28 (FIG. 7) Any process or process and assembly means known in the prior art can be used here. Of course, the mounting plates 22 to 25 can also be provided with suitable surfaces. or recesses or openings, in order to obtain a satisfactory anchoring and a

  high load capacity assembly between these plates and the

  step bearings 20.21 or their blocks 27.

  Housings 29 are arranged in the mounting plates 24.25

  for fixing means 30, for example threaded bolts or no-

  particularly metal or plastic self-tapping screws, with the help of which the base plate 10 of the front jaw 4 or a base plate 31 of the rear jaw 5 can be fixed respectively to the

mounting plate 24 or 25.

  The bearing assemblies 20, 21 are assembled by means of other fixing means 32, for example screws with

  wood, to a central part of the ski made up of wooden profiles 33.

  But it is of course also possible to use Parker or other screws, which are screwed into corresponding inserts of the ski, made of metal or of high-strength plastic, of the ski With a view to inserting the means

  fixing 32, the bearing sets 20,21 are provided with

  holes 34 which are larger than the largest section of the fixing means, perpendicular to a surface of the ski 1 A diameter 35 of these holes 34 is chosen so as to allow, relative to

  example to a screw head 36 of the screw constituting the fixing means

  tion 32, an unimpeded movement of the mounting plate 24 while

  perpendicular to the surface than perpendicular to the direction

gitudinal (arrow 13) of ski 1.

  FIG. 3 shows that a protruding end 37 of the fixing means 30 is less than a thickness 38, which allows compression of the bearing bodies 26 over an extent 39 As also shown in FIG. 3, it is of course possible to provide a diameter 35 of the hole 34 significantly greater, for example, than the diameter of the screw head 36, which also allows lateral offsets of the two

  mounting plates 22,24, with simultaneous crushing of the body

link 26 over the entire extent 39.

  FIG. 3 also shows that the ski 1 can comprise, in addition to the wooden profiles 33 which usually constitute the central part, corresponding intermediate layers 40, an upper layer 41 and a sliding face coating 42, thus than

edge profiles.

  FIG. 2 also shows that the mounting plates 22, 23 which are turned towards the surface 43 of the ski 1 can have an elasticity oriented in the longitudinal direction of the ski 1. This can be obtained by the fact that the mounting plates 22, 23 consist of a plastic plate which has weakening sections extending perpendicular to the longitudinal direction of the ski. However, in order to obtain the necessary elasticity in the case for example of metal mounting plates 22, 23, it is possible to also make these plates from articulated elements arranged perpendicular to the longitudinal direction of the ski, in the form of a link band or in several pieces, and arrange them at a mutual distance in the direction

longitudinal of the ski.

  Note that in order to better highlight the inventive solution,

  the representations of figure 1 and the following figures are often

  wind at a distorted scale and some parts have been shown

  disproportionately enlarged.

  We will now explain, using the diagram representation

  Figure 2, the operation of the bearing assemblies

*, 21 configured in accordance with the invention.

  In the unsolicited state, the ski 1 takes the position shown in solid lines in FIG. 1 or also in dotted lines in the figure.

  2, position in which the sole 16 extends approximately pa-

  paralleling to a surface 43 of the ski 1 This simplified representation of the position of the ski 1 was chosen in order to be able to better explain the action of the assembly device according to the invention In reality, the skis 1 have a prestressing This prestressing has for effect that in the unsolicited state, the ski 1 does not rest on a flat surface in the region of the assembly device, but is in contact with the ground only before and after the assembly device In the region where the assembly device is located, the ski does not apply

  so usually not on a flat surface.

  When using ski 1, passing through basins, and in particular descending from bumpy tracks, the ski rests on runway 44 only in its front end region and in its final region The ski is thus deformed in the position visible in FIG. 2 The assembly device 3, which is constituted by a length 45 of the sole 16 and by the length of the front and rear jaws 4.5, then constitutes a rope relative to the shape of arc formed by the ski 1 Depending on the deformation of the ski 1, while the radius of curvature 46 decreases, a difference 47 between the mounting plates

  23.25 which are overlapped in the rest position (Figure 1), diff-

  ference which was represented schematically and strongly exaggerated for a better understanding, does not cease increasing in the direction

  longitudinal of the ski If the front jaw 4 or as the case

  rear choir 5 is rigidly fixed to the ski, as is the case for the most recent known ski bindings, the length modifications produced by the differences 47 are compensated by a corresponding elastic system, as described for example in the

Patent AT-334,560.

  On the other hand, in the arrangement according to the invention, the longitudinal offset between the two mounting plates 22, 24 and 23, 25 is compensated to a preselectable extent, preferably entirely, by a corresponding deformation of the bearing body 26 or still from block 27 So there is no need for relative displacement of the housing 15

  of the rear jaw 5 relative to the base plate 31 which

  But it also means that the forces by which the ski boot 2 is fixedly clamped between the sole supports 7

  The release values, at which the sup-

  sole ports 7 must release the ski boot 2 in order to avoid

  injuries of the user of such a ski 1, are therefore not modi

wronged.

  To allow this relative offset of the mounting plates

  22.24 or 23.25, blocks 27 are compressed in their regions by-

  mutually opposite bodies, elongated in their partial opposite regions and simultaneously stretched in the longitudinal direction of the ski (arrow 13) According to the elastic characteristics, such as for example the hardness and the resistance to deformation or the modulus of elasticity, the force necessary for the deformation of the blocks 27 is

  more or less important, or more or less strongly depreciated In function

  tion of what, the ski will adapt quickly and therefore better or less

  pidly, to the irregularities of runway 44 In this context, it is

  of course also possible to endow the blocks 27 with elasticities or

  core with different resistance characteristics, for example in the longitudinal direction of the ski (arrow 13) of the ski and perpendicular to its surface 43 It is thus possible, for example, to oppose the deformation of the blocks 27 in the longitudinal direction of the ski, deformation which is due

  flexion of the ski, less resistance than deformation in di-

  section perpendicular to the longitudinal direction.

  In addition, thanks to the use of sets of bearings 20 and 21, and especially of the elastically deformable blocks 27, the shocks transmitted by the ski 1 to the boot 2 both perpendicularly to the surface 43 and in any other spatial directions are

  considerably amortized, and the stress on the user, and no-

  so much of his spine, is therefore reduced.

  In addition, by having a respective bearing assembly in the

  region of the front jaw 4 and the rear jaw 5, deforms them

  respective mations which appear in these regions, which are event-

  different, can be directly received and compensated, so that the relative compensation during shifts of ski 1 can

  be done uniformly with respect to the front jaw 4 and the jaw-

  rear choir 5, and not only in the region, for example, of the rear jaw This gives a better appearance of the flexion curve of the ski, compared for example to what it was with assembly devices in which a length compensation was only carried out in the region of one of the two coupling parts,

  namely either the front jaw 4 or the rear jaw 5.

  At the same time, this solution also compensates for the warping error which, with front 4 and rear 5 jaws fixedly mounted on the surface 43 of the ski 1, comes from the fact that the supports

  sole 7 are arranged at a distance perpendicular to and above

  above the surface 43 of the ski Thanks to the free movement in height of the mounting plates 23, 25 assembled to the front jaw 4 or rear, these plates assume a position parallel to the sole 16 of the ski boot 2 and therefore to the rope formed by the latter, instead of taking a tangential position with respect to ski 1, as

  this is the case with a fixed mounting on the surface 43 of the ski 1 In use

  reading an assembly device according to the invention, there is therefore no need for an expensive elastic mechanical system to compensate for the

  different pressure forces between the sole supports 7 which

  appear as a result of warping of the parts of the coupling device.

  As also shown in Figure 3, it is possible to modify

  proud the shape of the mounting plate 22, which can be for example in

  U-shaped or provided with guide plates 48 extending perpendicularly

  rement on the surface 43 These guide plates 48 can constitute a slide 49 for the lateral edges 50, 51 of the mounting plate 24 which are turned towards them. As shown in particular in the top view of FIG. 4, this embodiment has the advantage that, during the different offsets between the mounting plates 22, 24 or 23, 25 which appear following the deformation of the ski 1 shown on

  Figure 2, we can obtain a precise transmission of the lateral forces.

  rales from the ski binding or the boot 2 on the ski.

  The steering movement that the skier prints via his feet on ski 1 is thus neither delayed nor deformed, but takes

  effect directly and without modification.

  In this case, it is of course possible to place between the guide plates

  dage 48 and the lateral edges 50,51 of the damping materials cor-

  corresponding, for example blocks or plates of high resistance plastic, in order to allow a certain damping before the direct force transmission takes effect between the mounting plates 23 and 25 and the guide plates 48 or even the branches of the U-profile. FIG. 5 represents another alternative embodiment, in which the mounting plate 22 and the mounting plate 24 are configured in U-profiles 52, 53 in the region of the front jaw. 4 In addition, the mounting plate mounting 24 simultaneously constitutes the base plate 10 for the housing 6 of the front jaw 4 The two U-shaped sections 52, 53 are designed such that an external width 54 of the U-shaped section 52 corresponds approximately to an internal width

  between the branches 46 of the U-shaped section 53.

  The configuration of the mounting plates 22,24 in U-shaped sections 52,53 allows, as has already been described with the aid of FIG. 2, precise lateral guidance of the mounting plates relative to the other, but also, with a corresponding configuration of the block 27 of the bearing body 26, a possibility of sufficient relative adjustment in the longitudinal direction of the ski or even perpendicular to the

surface 43 of the ski.

  When designing the block 27 or the bearing body 26, it must be taken into account that it must have a thickness 57 which is greater than a length 58 of the branches of the zen profile U 52, but which is less than the sum of the length 58 of the branches of the U-shaped profile 52 and a length 59 of the branches 56 of the U-shaped profile 53 Thanks to the difference between the length 58 of the branches of the U-shaped profile 52 and the thickness 57 of the block 27, a compression stroke 60 can be predefined In addition, this embodiment guarantees that there is already an overlap between the branches of the U-shaped sections 52 and 53, in directions perpendicular to the longitudinal direction of the ski, when the device d the assembly is not stressed, which allows, in all operating conditions, a reliable transmission of the forces of

  lateral guide of ski boot 2 on ski 1.

  In this embodiment, the figure also schematically shows that the block 27, which for example consists of a

  elastomer, foam plastic, rubber or any mixtures

  conch of these materials, can, using intermediate layers 61, for example éa u dains uainnliq-ps dethz 1 if Is in a = i TL i cdi carbon or fiberglass, or by a configuration in sandwich

  blocks 27, to allow the transmission of forces to be higher

  between the mounting plates 22,24 or 23,25 And above all, by a

  appropriate distribution of the direction of action of the intermediate layers

  diaries 61, one can also act on the damping characteristics or the resistance to deformation of the blocks 27 in spatial directions different from each other, or

  further adapt them to desired values.

  Figures 6 to 8 show another alternative embodiment

  of an assembly device 3 according to the invention, in which the material

  front chuck 4 and rear jaw 5 are arranged, completely

  depending on one another and without any assembly by means of a spacer 12, on a bearing plate 62 or even on a mounting plate 25 designed as a base plate 63. Since this embodiment uses most of the elements of the embodiments previously described according to FIGS. 1 to 5, the same reference numerals have been used for

  parts that remain unchanged.

  While, as shown in particular in FIG. 7, the front jaw 4 is fixed by its base plate 10 to the bearing plate 62 by means of fixing means 64, which are here threaded bolts, the housing 15 of the rear jaw 5 is directly attached

  by its base plate 31, by means of a retaining device

  glage 65, on a base plate 63 which constitutes the mounting plate

  It should of course be mentioned here that we can configure both the

  choire before the rear jaw as shown in figure 7

  or 8, or else use, within the framework of the invention, a combination

  any of the sets of bearings 20.21 described on the same ski 1.

  The adjustment of the front jaw 4, in order to adapt to different sizes of the ski boot 2, can for example

  be effected by the fact that the housings 29 for the fixing means

  tion 64 are arranged in several copies, with a spacing 66, on the bearing plate 62 This spacing 66 can always be the

  even - or variable, or increase or decrease gradually -

  It is thus possible, as shown in Figure 6 by dotted lines and

  mixed lines in the front jaw region, raise the jaw

  choir before 4 at different relative positions in the long direction

gitudinal (arrow 13) of ski 1.

  The bearing plate 62 can then remain the same, even for different shoe sizes, but with identical front 4 or rear 5 jaws, and it is each time fixed to the ski 1, by

  through the bearing bodies 67 to 69, at the average value

  finished as avorable for the different adjustment positions.

  The advantage is that, by the arrangement of three bodies of pa-

  separate liers 67 to 69, a statically defined fixation of

  the front jaw 4 on the ski 1 and the resistance can be reduced

  bale to deformation thanks to the smaller cross section of the body

  liers 67 to 69 In addition, the shear forces which appear in the different spatial directions inside the bearing bodies during the deformation are thus reduced As already described with the aid of the preceding figures, the bodies of bearings 69 are respectively fitted with mounting plates 22, 24, and assembled by means of these plates, by fixing means 30 or 32, to

  the bearing plate 62 or else on the ski 1.

  The embodiment of the assembly device 3 which is shown

  shown in Figure 8 for fixing the rear jaw 5 on the ski 1, certainly also has three bearing bodies 67 to 69 arranged independently of each other, but they are assembled on a mounting plate 25 common for the three bodies , as shown for example in FIG. 7, by a layer of glue 28 or by a process of vulcanization, injection or foaming However, the support and the fixing of the bearing bodies 67 to 69 on the ski takes place, according to the alternative embodiment already described with the aid of FIG. 7, by means of independent mounting plates 22. In this alternative embodiment, it turns out to be advantageous to insert, before the positioning of the plate mounting 25 in the ski 1, anchor pivots 70, after which the plate is threaded

  25 fitted with bearing bodies 67 to 69 and fixed in place

  sition on the ski 1 using a fixing device in position 71 schematically shown, for example a ball lock or the like operable from the outside In the region of the rear jaw 5, it can be seen that a device 65 is provided for

  adjust this jaw to different relative positions relative to

  wearing the ski in the longitudinal direction (arrow 13) of the latter,

  positive which consists of mutually corresponding teeth 72 on the opposite sides of the base plate 31 and the mounting plate 25 The rear jaw 5 can be moved relative to the ski 1, in its longitudinal direction (arrow 13), in accordance with the pitch of the teeth of the toothing 72, and fixed in the desired position by

  by means of a fixing means 73.

  In the present embodiment, in order to avoid, during use, an undesirable modification of the tightening of the ski boot 2 between the front jaw 4 and the rear jaw 5, and in order to thus obtain a reliable release of the safety fastening, the

  mounting plate 25 and bearing plate 62 are now mutual-

  Lement assembled by means of a spacer 74.

  In order to allow, for example, an adaptation of the distance between the front jaw 4 and the rear jaw 5 for different shoe sizes, without moving these jaws relative to the bearing plate 62 or even to the base plate 63, the spacer 74 may consist of two traction bands 75 and 76, which can be fixed at different relative positions by means of an adjustment device 77 having an adjustment stroke 78 But it is also possible to use a continuous spacer element 74, in one piece This gives a fixed relative position of the front jaw 4 and the rear jaw 5, independently of the

  deformations of bearing housings 67 to 69 If adaptation to dif-

  different shoe sizes is then effected by a modification of the total length of the spacer 74, the relative movement, necessary for this purpose, between the mounting plates 22, 24 or 23, 25 can be carried out by a corresponding equivalent deformation of

bearing housings 67 to 69.

  Such an embodiment is mainly suitable for ski bindings which have already been on the market for a long time and which it is desired to provide the advantages of the invention with a minimum of costs.

modification.

  In addition, this exemplary embodiment shows that the spacer 74 can be pivotally assembled around axes 80, by means of an articulated assembly 79, to the base plate 63 or

  to bearing plate 62 or to mounting plates 25 or 24.

  The assembly can then be carried out by means of a pin 81 By providing several different housings 82 in the plate

  mounting 24 or 25 for pin 81, it is also possible, by introducing

  s the pin 81 in different housings 82, modify the

  tance between the sole supports 7 of the front jaw 4 and the

rear jaw 5.

  Thanks to the articulated assembly 79, it is now possible, when entering with a ski boot 2 into the assembly device 3 according to the invention, to adjust to a certain extent the front jaw 4 and the rear jaw 5 to the boot, in order to be able to compensate for inaccuracies or even a shift of the application faces in the longitudinal direction of the ski, without creating forces

deformation.

  In the embodiment shown in FIGS. 9 and 10 of an assembly device 3 according to the invention, the mounting plate 22 or 24 for the front jaw 4, or also the mounting plate 23

  or 25 for the rear jaw 5, is slidably mounted in a

  longitudinal guide positive 83 In the simplest case, this

  device may consist of a guide slide 84, dry-

  tion in C, which receives the mounting plate 22 or 23 and which, like the

  schematically shows figure 9, can be provided with notches available

  located in the vertical branches of the C Thanks to these notches, the

  longitudinal guide positive 83 can allow an adjustment range

  of corresponding value of mounting plate 22 or 23, without any-

  times stiffen the ski in an undesirable way vis-à-vis bending perpendicular to the surface 43 The assembly between the bearing bodies 26 and the upper mounting plate 24 or 25 can

  be carried out in accordance with the embodiments previously described

  crits Similarly for the assembly between the mounting plates 22,23 and

the front jaw 4 or rear jaw 5.

  The main advantage of this solution is that it prevents

  excessive stress on the bearing housings during long shifts

  gitudinal between the front jaw 4 and the rear jaw 5 as well

  that ski 1 which, during deformations of the ski shown schematically for example-

  ple in Figure 2, appear as a result of the distance between the rope dimension and the arc dimension, since a major part of the longitudinal compensation can be obtained by a translation of at least one of the mounting plates sets of

steps 20.21.

  Of course, the different embodiments described above

  before, and the variants and the different embodiments presented

  ted in these exemplary embodiments, may constitute independently

  inventive solutions to each other but can also

  be combined with each other at will.

  The bearing housing can also have different deformation characteristics in different directions relative to

to the longitudinal axis of the ski.

  Thus, the resistance to deformation in the perpendicular direction

  area at the longitudinal axis of the ski and parallel to its surface can be

  larger than in the longitudinal direction of the ski or even perpendicular to

  lairement on the surface of the ski This can be obtained by the fact that the bearing body has several different elastic elements, -which are arranged at a distance from each other or which are joined by

  bonding between a common block The different elastic elements can

  wind then have elastic characteristics or

different depreciation.
