Definitions

  • the invention relates to a safety ski binding with the features according to the preamble of claim 1.
  • a simple structure and simple assembly of the soleplate or the holder should be retained.
  • the sole plate Since, according to the invention, the sole plate is centered in its central position by a lateral support of the pivot lever, as seen in the longitudinal direction of the ski, the spring load acting on the pivot lever, which must be overcome when the sole plate is triggered laterally, does not result in any tensioning of the sole plate and Bring skis in the longitudinal direction. Because in the longitudinal direction of the ski there is at best the frictional force between the pivot lever and the stop. At the moment of lateral release the pivot pin of the soleplate is therefore largely relieved of additional frictional forces, so that the soleplate can be pivoted easily even with high adjustment forces of the ski binding. In addition, by eliminating the load on the ski section between the pivot pin and the holder, there are no adverse influences on the bending behavior of the ski.
  • a prerequisite for the intention of the invention to keep the ski binding free from holding forces effective in the longitudinal direction of the ski is, seen in the longitudinal direction of the ski, the lateral arrangement of the stop relative to the pivoting lever. This is achieved by each arrangement of the pivot axis of the pivot lever in a plane parallel to the longitudinal direction of the ski and between a position parallel to the surface of the ski that is perpendicular to it.
  • an upright is preferred
  • Sole holder of the sole plate can be arranged.
  • the swivel lever protrudes from the soleplate and the stop is fixed to the ski or vice versa.
  • an arrangement of the pivoting lever or the pivoting levers on the sole plate and the stop on a base plate firmly connected to the ski is preferred.
  • the pivot lever then advantageously extends forwards in the longitudinal direction of the ski, starting from its pivot axis. If, as mentioned, the pivot lever is to center the sole plate in its central position, then a stop against which it rests must be assigned to each of the two side surfaces of the pivot lever. In this case, the swivel lever protrudes
  • the holder is therefore equipped with two pivoting levers preferred which are loaded feder ⁇ in opposite pivoting directions and lie under the spring load on the stop. Since the two pivot levers can be pivoted independently of one another, deviations between the position of the pivot levers and the stop caused by assembly and production are compensated by the spring loading the pivot levers.
  • Swivel levers lie between the two stops and are spread apart by the spring load in their holding position.
  • the preferred arrangement of the pivot lever or levers so that they are attached to the soleplate and directed from their pivot axis towards the ski tip brings an additional advantage in that the lever arm is extended in the event of a ski deflection and the resulting relative movement of the stop to the pivot lever towards the front and thereby the trigger force is reduced.
  • a particularly strong ski deflection which has a relative movement of the ski-fixed stop with respect to the pivoting levers to the front in the order of magnitude of 1 mm
  • Figure 1 is a side view of a safety ski binding according to the invention, partially cut and shown shortened in the longitudinal direction of the ski.
  • Fig. 2 shows a section along the line II-II in Fig. 1, and
  • Fig. 3 shows a section analogous to Fig. 2 of a modified embodiment of the holder.
  • the safety ski binding shown in FIG. 1 has a sole plate 1 which can be pivoted about a pivot pin 2 parallel to the surface of a ski 3, which is only indicated.
  • the pivot pin 2 is screwed onto the ski 3 by means of a base plate.
  • a heel holder 7 is fastened, which engages over the rear sole edge of the ski shoe 6 and is designed such that it releases the sole edge when an upward holding force which is dangerous for the skier is exceeded.
  • the front sole holder 5 and the heel holder 7 are not part of the present invention and are therefore not explained in more detail here. They can be of a known type and training (cf. EP-A 69 753).
  • a holder designated as a whole by 10 by means of which the sole plate 1 is fixed in its central position when in use and held in such a way that when one of the sole plates is exceeded Ski boot 6 can pivot to the side acting torque around the pivot pin 2.
  • the holder 10 consists of a spring part 11 fastened to the end section 8 in a manner not specified in more detail and a base plate 12 screwed to the ski 3, which holds a stop 13 in the form of an obliquely forwardly directed pin.
  • the spring part 11 has a housing 15, at the front end of which two pivot levers 17 which are symmetrical to one another are pivotably mounted by means of a bearing pin 16.
  • the swivel lever 17 has a bearing eye 18 which projects laterally to its longitudinal extension and which is on its rear side has a notch 19.
  • a bridge member 20 is supported, which is fastened to the front end of a guide pin 21, for example riveted, and is acted upon by a prestressed compression spring 22.
  • the compression spring 22 is clamped between the rear wall of the housing 15 and a spring plate 23 which is screwed onto a thread 2 of the guide pin 21.
  • the spring preload can be changed by a screw slot 25 at the rear end of the guide pin 21, since the spring plate 23 is not shown in detail
  • the pivot levers 17 are pivotally arranged one above the other on the bearing journal 16 with their bearing eyes 19, but are cranked in their further course, so that they lie in one and the same plane on opposite sides
  • the inner surfaces of the pivot levers 17 abutting the stop 13 are each designed in the manner shown in FIG. 2 to form a curve, the course of which shows the force / travel characteristic of the compression spring 22 when the pivot levers 17 are pivoted out laterally and thus the torque / pivot angle -Characteristic of the sole plate 1 determined when swiveling.
  • a torque / swivel angle characteristic is sought which, when the sole plate 1 is moved out of its central position, initially includes a steep increase in the release torque and then a constant torque during the further swivel until the final release.
  • the base plate 12 carrying the stop 13 has at its front end a link 28 which is gripped by an angled plate projection 29 of the sole plate 1.
  • the sole plate 1 is held at its end section 8 with respect to a movement perpendicular to the ski surface and is guided during its sideways pivoting.
  • the end section 8 of the sole plate 1 forms an angle of approximately 20 ° with the ski surface (FIG. 1).
  • the interacting components of the holder 10 are aligned, ie the spring part 11 including the pivot lever 17 is inclined at the same angle to the ski surface and the stop 13 accordingly has an inclination to the perpendicular to the ski surface from this angle, too, so that in parallel to the ski surface of the sole plate 1 Seitier ⁇ move the pivot lever 13 can slide n circumferential direction on the cylindrical peripheral surface of the stop pin 17th
  • the flange of the pivot pin 2 which can be seen in FIG. 1, can be removed in a manner not specified, so that the pivot pin 2 can be inserted into a corresponding recess 2 '. Since, under the action of the compression spring 22, the pivot levers 17 are pivoted against one another until their inner surfaces abut against one another, the pivot levers are pushed onto the stop pin 13 when the soleplate 1 is placed with the opening formed by the grooves 26. Then the sole plate can be moved to the rear, so that the. Impact pin 13 spreads the pivot levers 17 apart and brings them into their holding position. In this position, the sole plate 1 with the recess 2 'on the pivot pin 2 and fastened by replacing the flange.
  • the operation of the safety ski binding according to FIGS. 1 and 2 is as follows: If a lateral torque is exerted on the sole plate 1 by the ski boot 6, which remains below a limit value set on the compression spring 22, the sole plate 1 becomes mutually opposed centered on the stop 13 canceling lateral support forces of the pivot lever 17 in their central position. If the torque acting on the soleplate 1 increases to such an extent that the spring preload is overcome, one of the pivot levers 17 is deflected in accordance with the direction of the torque while the soleplate 1 is pivoted sideways in the system at the stop 13. As a result, the bridge member 20 is displaced rearward by means of the locking notch 19 of this pivot lever 17 and the compression spring 22 is thereby further compressed.
  • the sole plate 1 is pivoted further while maintaining the pivoting of the corresponding pivot lever 17 until the ski boot is completely released from the sole plate 1 if the front sole holder 5 or the heel holder 7 responds is released.
  • the pivoting levers 17 are also moved relative to the stop 13 with the soleplate 1 as the pivoting angle of the soleplate 1 increases. However, there is no further pivoting of the pivot lever 17 and therefore no further compression of the compression spring
  • FIG. 3 differs from the one described above essentially only in that the pivot levers 17 'are each individually supported on their own journal 16' and are spread apart by the compression spring 22 '.
  • the guide pin 21 'itself forms a bridge member with its front end face 20', in that the end face 20 'presses on one shoulder 19' of the pivoting lever 17 '.
  • the pivot levers 17 ' protrude between two stops 13' and rest on their outer surfaces under the action of the compression spring 22 '. These outer surfaces are in turn designed to form a curve which defines the torque / swivel angle characteristic of the soleplate in the same way as explained above.
  • the part of the shoulder 19 'which extends parallel to the guide pin 21' has the lateral distance from the front end of the guide pin 21 'shown in FIG. 3, which is dimensioned such that this part of the shoulder extends at a certain spreading angle Swivel angle 17 'is applied to the outer surface of the guide pin 21' and a further spreading of the swivel levers 17 ' prevented. This enables the pivoting levers 17 'to be inserted between the stops 13' when the sole plate 1 is placed on the ski.
  • the pivot levers 17 ' can be arranged in the same plane, since when the sole plate 1 swings out to the side and the resultant pivoting of one of the pivot levers 17' inwards, the other pivot lever 17 ', which is then no longer under the spring load, can yield . However, it is also possible here to crank the pivot levers 17 'in such a way that they can also pivot over one another in the course of their pivoting movement.
  • the bridge member 20 (FIG. 2) or the end face 20 ′ of the guide pin 21 ′ (FIG. 3) forming a bridge member is designed symmetrically to the longitudinal axis of the respective guide pin 21 or 21 ′.
  • the bridge member 21 or the end face 20 presses the pivot levers 17 or 17' into a central position centered on the ski.
  • the sole plate 1 and with it the ski boot of the skier standing thereon are held in the corresponding center position centered on the ski.
  • the construction according to the invention also allows a targeted decentred position of the sole plate 1 relative to the ski.
  • Such a targeted, decentred position is particularly desired by ski racers in order to enable the skis to be aligned very precisely in relation to the individual foot position of the skier.
  • one side of the bridge member 20, which is supported in the associated notch 19 of the one pivot lever 17, can be kept shorter than the other side. This allows the Swivel the shorter part of the bridge member 20 associated pivoting lever 17 further to the rear, while the pivoting lever 17 associated with the longer part of the bridge member 20 is pivoted further forward.
  • the resultant equilibrium position of the pivot levers 17 thus results in an eccentric position of the opening formed between the two pivot levers 17, in which the stop 13 is located.
  • the sole plate ⁇ 1 is correspondingly off-center of the ski, ie, held at an angle with respect to the ski longitudinal axis relative to, as long as no lateral force acts on the set of the compression spring 22 limit.

  • the end face 20 'thus does not form a right angle with the longitudinal axis of the guide pin 21' - as can be seen in FIG. 3 - but an angle deviating from 90 °.

Abstract

L'invention concerne une fixation de ski de sécurité comprenant une plaque de semelle pivotant parallèlement par rapport à la surface du ski et qui est reliée au ski (3). La plaque de semelle est fixée dans une position centrale, de façon qu'elle ne puisse pas pivoter latéralement par rapport au ski, au moyen d'une fixation (10) soumise à la sollicitation d'un ressort et placée à l'extrémité arrière de ladite plaque de semelle. Cependant, si un certain couple de rotation prédéterminé est dépassé, la plaque de semelle peut pivoter latéralement par rapport au ski en surmontant la force de sollicitation du ressort. Pour éviter que le pivot de la plaque de semelle (1) et le ski lui-même soient sollicités par la force exercée par le ressort (22), il est prévu que la fixation (10) soit pourvue de leviers de pivotement (17) qui, lorsqu'ils sont en position de retenue, position dans laquelle ils maintiennent la plaque de semelle (1) dans sa position centrale, reposent contre une butée (13) placée à côté desdits leviers de pivotement, transversalement par rapport au ski.
