Definitions

  • the invention relates to a ski binding for a cross-country or touring ski according to the preamble of claim 1.
  • a holding shell is provided for receiving the front area of a cross-country ski boot.
  • the holding shell has a base plate with a recess for a locking pin and, at a distance above it, retaining strips, the base plate and retaining strips being designed to converge towards the front.
  • the associated cross-country ski boot has a U-shaped bracket on its front end area, which forms an opening with the sole of the boot. The locking pin protrudes into this opening in the closed position of the ski binding.
  • the front sole area of the cross-country ski shoe is provided with upper and lower guide surfaces, which guide surfaces are designed such that they are supported on the base plate and on the guide strips of the holding shell when the ski shoe is inserted.
  • the invention has set itself the task of designing the holding shell in a ski binding of the type mentioned in such a way that wear-related changes in the outsole of the cross-country ski boot no longer have an effect on the support thereof in the holding shell.
  • the set goal is achieved according to the invention by the characterizing features of claim 1. Characterized in that the bottom plate of the holding shell with at least one raised Provided area on which the inserted ski boot with its bracket or crossbar rests, the support of the cross-country ski boot in the holding shell is guaranteed independently of possible wear of the outsole.
  • the measures of the characterizing features of claim 2 provide a particularly advantageous embodiment of the raised areas while at the same time making the holding shell more compact.
  • claim 3 have the effect that the crossbar of the cross-country ski boot is particularly secured against unintentional sliding out to the rear.
  • the configuration according to the features of claim 4 ensures a construction of the holding shell that is favorable in terms of production and, in particular, that it is easier to remove from the mold.
  • a base plate 2 of a cross-country ski binding is mounted on a ski 1 in any known manner.
  • the base plate 2 has a bearing block 3 on which a holding shell 5, which is described in more detail below, is pivotably mounted on a transverse axis 4.
  • a pivot part 6 is also mounted on the transverse axis 4.
  • the pivoting part 6 carries a locking pin 7 on one arm and a further transverse axis 8 on its other, upwardly directed arm, to which a bolt 9 designed as a two-armed lever is articulated.
  • the holding shell 5 articulated on the transverse axis 4 essentially has a base plate 51 with a recess 52.
  • side walls 53 adjoin each.
  • the side walls 53 are provided at their upper ends with holding strips 54 directed inwards, that is to say towards the longitudinal axis.
  • the holding shell 5 has in its area facing the transverse axis 4 a transverse web 55 with a locking groove 56.
  • a lever arm of the bolt 9 designed as a locking lug 10 engages in this locking groove 56 in a known manner.
  • a cross-country ski boot labeled 20 is inserted into the holding shell.
  • the cross-country ski boot 20 has a sole 21, in the front end region 22 of which a U-shaped bracket 23 is anchored in a known manner. This creates an opening 24 between the bracket 23 and the sole 21, into which the locking pin 7 projects when the ski binding is closed.
  • the front end region 22 of the sole 21 has wedge-shaped upper and lower guide surfaces 25 and 26, the lower guide surface 26 being intended to rest on the base plate 51 of the holding shell 5.
  • the angle between the upper 25 and lower guide surfaces 26 is the same as the angle between the guide strips 54 and the base plate 51 of the holding shell, since when the ski boot 20 is inserted into the binding, the upper guide surface 25 should rest against the guide strips 54 of the holding shell 5 from below.
  • FIG. 1 it can be seen that the lower guide surface 26 wears out after long use of the cross-country ski boot 20 and is no longer in contact with the base plate 51. This situation is shown in broken lines and the worn lower guide surface is designated by 26 '. As a result of this wear, the cross-country ski boot 20 is no longer held securely and without play in the holding shell 5.
  • the base plate 51 has side surfaces 57. In their section closer to the transverse axis 4, the side surfaces 57 are provided with regions 58 which are raised relative to the base plate 51. As shown in the drawing, these raised areas 58 can be formed approximately parallel to the base plate 51.
  • This embodiment variant is particularly favorable in relation to the simplest possible design of the injection mold and the ease of demolding. However, it is also possible to design the raised areas 58 to be inclined forward. This solution will be chosen if emphasis is placed on a particularly secure hold of the bracket 23 in the ski binding.
  • the bracket 23 of the cross-country ski boot 20 rests on the raised areas 58 of the base plate 51.
  • wear of the lower guide surface 26 or 26 'of the sole 21 no longer has a negative effect on the positioning of the cross-country ski boot 20 in the holding shell.
