Definitions

  • the invention relates to a combination of a ski binding and an associated ski boot for a cross-country or touring ski according to the first part of patent claim 1.
  • the holding shell and the pivoting part can be pivoted about a common transverse axis against an elastic element, which by a bearing block mounted on the ski is held, the transverse axis being in the front region of the two components mentioned and a spring holding shell and pivoting part acting in the sense of a spreading apart.
  • the bolt is mounted on an extension of the swivel part on an axis and, in the closed position of the binding, engages in a transverse web of the holding shell provided with a locking groove.
  • the invention has set itself several objects to overcome the disadvantages of this older solution, which are discussed below.
  • the first task is to improve the retention of the ski boot in the holding shell, if necessary even when there is snow in the binding.
  • the measures according to the invention according to the characterizing features of claim 1 ensure good retention of the ski boot in the holding shell.
  • the optimal angle of the contact surfaces is set at approximately 45 °, so that on the one hand the longitudinal displacement of the ski boot does not become too great when there is snow on the contact surfaces, which would be the case at smaller angles and thus to a large load on the locking pin or the hooking element would lead, and on the other hand the ski boot is still provided with sufficient lateral support by the contact surfaces, which would no longer be the case at larger angles.
  • the front region of the ski boot is designed in a particularly advantageous manner.
  • the features of claim 4 allow a particularly good fit of the hooking element on the locking pin.
  • the features of claim 7 determine the support surfaces on the ski boot with which it is supported on the contact surfaces of the holding shell.
  • the features likewise determine the guide surfaces of the ski shoe, namely that the lower guide surface of the ski shoe rests on the bottom of the holding shell and the upper guide surface rests on the guide strips of the holding shell from below.
  • claims 8 and 9 describe various openings in the holding shell, by which it is ensured that snow in the binding is pressed out when boarding. In cooperation with the features of claims 4 and 5, the snow in the binding is led to the openings in the holding shell.
  • the second task is to provide the latch with additional security without increasing the number of components.
  • the bolt has a further lock, so that an unwanted unlocking while walking is not possible due to blows and bumps.
  • the third task is to ensure that getting into the binding always takes place under controlled conditions.
  • the features of claim 12 cause that the pivot angle of the bolt when closing the binding is equal to the minimum pivot angle when opening the same.
  • the position of the bolt and the holding shell relative to one another is determined in the open position of the binding.
  • the bolt must be held by the user with the ski stick in the position in which he releases the pivoting part during the entire alighting process.
  • the invention therefore has the fourth object to eliminate this disadvantage and one To create ski bindings where the user has the opportunity to support himself with both ski poles in the cross-country ski trail during the alighting process.
  • a ski binding for cross-country skiing according to DE-OS 34 05 861 has a base plate arranged under the ski boot sole, which continues towards the tip of the ski in two cheeks, between which a handle lever, which is under the influence of a leg spring, is pivotably arranged on a transverse axis .
  • the leg spring presses the handle lever against a hold-down device for the sole of the ski boot, which can be pivoted about a further transverse axis arranged between the cheeks, on which a step spur is also mounted. The end of the latter engages in a recess in the sole of the ski boot from below.
  • the hold-down In the entry position of the binding, the hold-down is held by the handle lever in that a guide curve of the handle lever engages over a cam of the hold-down.
  • the cam moves along the guide curve, and when the culmination point is exceeded, the hold-down device is pivoted into the locked position.
  • This binding has the disadvantage that the step movement of the skier is brought about only by the elasticity of the sole of the ski boot, but not by an articulated flap in the binding.
  • This known solution therefore differs generically from the object of the invention.
  • claim 17 eliminates the risk of the end of the leg of the leg spring being spiked in the bolt.
  • the measure of claim 18 makes it possible for the bolt to automatically return to its latching position as soon as the end of the leg has been pressed by the crosspiece of the holding shell over the latching projection of the groove.
  • the first embodiment according to FIGS. 1 to 7 and 10 to 12 represents a ski binding for a cross-country or touring ski 1 and an associated ski boot 100.
  • a bearing block 10 is mounted on the top of a ski 1 by means of indicated screws 2. It consists of a base plate 11 with two walls 12, which begin at the front end of the base plate 11 facing the ski tip and lead approximately to the middle of the base plate 11 and carry a transverse axis 20 in the latter area.
  • the base plate 11 carries at its front end a rib 13 and at its rear end a support surface 14 in which the screws 2 are countersunk.
  • a pivoting part 30 is attached, with its bottom 31 on the Support surface 14 of the bearing block 10 rests.
  • the bottom 31 has on its side facing away from the ski 1 from the longitudinal axis of the binding slopes 31 a sloping outwards.
  • the bottom 31 carries a locking pin 32 or bar.
  • a holding shell 40 is also attached to the transverse axis 20, the bottom surface 41 of which has an exemption 41b for the locking pin 32 and further openings 41a (FIG. 6).
  • Guide strips 45 are connected at the top to the side walls 42 of the holding shell 40, which are connected in their front part to a transverse web 43 which carries a latching groove 43a and in their rear region remote from the transverse axis 20.
  • An extension 33 of the pivoting part 30, which projects upwards from the transverse axis 20, carries at its upper end an axis 50 to which a bolt 60 designed as a two-armed lever is articulated, which on its arm facing the holding shell 40 has a groove-shaped stop 63 (FIG. 10 -12) and a detent 61 and on the side of the ski 1 facing away from its second arm carries a recess 62.
  • Corresponding cavities 31b are provided in the bottom 31 of the pivoting part 30 for a spring 70 about the transverse axis 20, which holds the holding shell 40 and the pivoting part 30 in the sense of spreading apart.
  • a locking spring 80 around the axis 50 acts on the locking bar 60 in the closing direction to the holding shell 40.
  • an elastic element 90 is used in such a way that its recess 91 comes to rest over the rib 13 of the base plate 11 and is supported on the pivot part 30 with its part facing away from the rib 13.
  • the elastic element 90 has a bore 92 in order to be able to use the screw 2 unhindered when mounting the binding on the ski 1.
  • the ski boot 100 according to FIG. 7 to be inserted into the binding has in its front area a sole extension 101 which is formed from extensions 101a and a U-shaped hooking element 102 cast into it with its legs 102a.
  • An opening 104 is formed between the hooking element 102 and the end face 103 of the sole.
  • the front region of the sole has wedge-shaped guide surfaces 105a, 105b, the lower guide surface 105b being intended to rest on the bottom surface 41 of the holding shell 40.
  • the angle between the upper 105a and lower guide surface 105b is the same as the angle between the bottom surface 41 and the guide strips 45 of the holding shell 40, since when the ski boot 100 is inserted into the binding, the upper guide surface 105a abuts against the guide strips 45 of the holding shell 40 from below should.
  • the sole area provided with the guide surfaces 105a, 105b has support surfaces 106 which, when the ski boot 100 is inserted, lie parallel to the contact surfaces 44 of the holding shell 40.
  • FIGS. 8 and 9 there are openings 42'a in the side walls 42 'of the holding shell 40' which widen outwards.
  • the ski boot 100 'belonging to this embodiment has beveled surfaces 102'c on the outer surface of the hooking element 102' surrounded by sole material.

  • the locking pin 32 penetrates the opening 104 in the sole extension 101 of the ski boot 100 from below.
  • the slope of the linear section 32a of the locking pin 32 serves in the first phase of the depression of the holding shell 40 to facilitate the threading of the locking pin 32 into the opening 104 until the ski boot 100 rests with its support surfaces 106 on the contact surfaces 44 of the holding shell 40.
  • the hooking element 102 continues to move along the linear section 32a, but with increasing tension.
  • the tension remains constant as the hooking element 102 moves along the circular arc section 32b to its final position, since the circular arc section 32b is centered in the transverse axis 20 Has.

Abstract

Fixation de ski ci-décrit avec une enveloppe de retenue (40) qui se déplace avec une pièce pivotante (30) et qui, pour assurer une transition entre une position ouverte et une position fermée par rapport à la pièce, est montée de manière pivotante sur un axe transversal horizontal (20) qui résiste aux mouvements de ski, la position fermée de la fixation étant bloquée par un élément (60) de verrouillage à ressort. La partie pivotante (30) comporte un élément de blocage (32) qui en position fermée de la fixation s'engage dans un évidement sur l'enveloppe de retenue (40). Ladite enveloppe (40) recouvre la protubérance avant (101) de la semelle d'une chaussure de ski (100), alors que l'élément de blocage (32) descend également à travers une ouverture (104) dans la protubérance (101) de la semelle. En position ouverte de la fixation, par contre, l'élément de blocage (32) est éloigné de l'intérieur de l'enveloppe de retenue (40). Selon l'invention, l'enveloppe de retenue (40) et la partie pivotante (30) sont montées de manière pivotante sur un axe transversal commun (20), fixé sur un bloc de support (10). Le pivotement combiné de l'enveloppe de retenue (40) et de la partie pivotante (30) est réalisé contre l'action d'un élément élastique (90). La partie pivotante (30) porte, sur une protubérance (33) orientée vers le haut, la pièce de blocage (60) qui, en position de blocage de la fixation, s'engage dans l'enveloppe de retenue (40). Un ressort (70) écarte l'enveloppe de retenue (40) de la pièce pivotante (30).
