Definitions

  • the invention relates to a releasable ski binding with a shoe or sole holder pivoting when triggered about a ski-side vertical axis, which by means of a spring-loaded piston, which is displaceable within a longitudinally non-rotatable guide in the longitudinal direction of the ski, in the shoe or sole is pressed in the essentially ski-fixing normal position, in the projections or recesses on the shoe or sole holder end of the piston on both sides of a vertical plane containing the vertical axis and extending in the longitudinal direction of the ski from the spring force urging the piston against the shoe or sole holder in centering engagement with Recesses or projections of the shoe or sole holder are held.
  • the shoe or sole holder and the piston in the normal position form a practically rigid unit held together by the spring force, which only within the scope of the play of the piston within the guide or the play of the shoe or sole holder on the vertical axis is able to perform movements.
  • the piston in the previous bindings is unable to follow this movement component oriented in the ski cross direction due to its largely play-free bearing in the guide in the ski cross direction. Accordingly, larger relative movements involving friction occur inevitably between the one side of the shoe or sole holder and the piston when the trigger is pivoted, that is to say the trigger pivot is counteracted by a further greater frictional resistance, which is heavily dependent on contamination of the areas of the shoe or sole holder and piston sliding on one another .
  • the invention is based on the general idea of arranging the end of the piston on the shoe or sole holder side so that it can move in the direction of the ski, so that the projection and the recess or the projections and the recesses respectively engage when the shoe or sole holder is pivoted remain, only interact with each other in the manner of joint elements and accordingly larger sliding movements between these elements relative to one another are avoided. This can significantly reduce the friction between the piston and shoe or sole holder.
  • the binding such that the Protrusions and recesses in the normal position on the shoe side of a vertical plane containing the vertical axis and extending in the transverse direction of the ski are such that the protrusions and recesses which remain in engagement with one another on one side of the shoe or sole holder when the trigger is pivoted with maximum pivoting of the shoe or sole holder take a position on the other side of this vertical plane and the distance to this vertical plane is approximately the same size as in the normal position.
  • the guide is essentially only open at its end on the shoe or sole holder side - for the piston parts protruding from the guide - and the space between the guide and the shoe or sole holder is closed off by a bellows-like cover.
  • Soiling of the elements essential for the release resistance of the binding can be avoided in a structurally particularly simple manner.
  • the projections or the like as narrow strips, wedges or the like. form, which practically only have line contact with the associated recesses. It can be used in conjunction with transverse mobility The end of the piston on the shoe or sole holder side can be achieved with almost no friction between the piston and the shoe holder.
  • the single figure shows a top view of a binding according to the invention, the lower half of the binding in the figure being drawn horizontally cut at the level of the piston axis.
  • the binding shown which serves to hold the front end of the sole of a ski boot, not shown, has a base plate 1, which is attached to the top of a ski and which integrally merges into a housing 2 in the direction of the ski towards the front or with the same in the state in which the ski is mounted is firmly connected.
  • a pin 3 approximately parallel to the ski vertical axis, is arranged in the center of the ski, on which a shoe or sole holder 4 is pivotably mounted.
  • This shoe or sole holder 4 has, in a generally known manner, the front sole region of the ski shoe, which has a leg 4 'which laterally encompasses the side with an edge 4' 'which overlaps the sole of the shoe.
  • the front part of the ski boot can thus be held in with the shoe or sole holder 4 held in place Ski direction are held while the edge 4 '' cooperates with the base plate 1 for vertical mounting of the ski boot.
  • the shoe or sole holder 4 On both sides of the pin 3, the shoe or sole holder 4 has, on its side facing the housing 2, approximately parallel grooves or grooves 5 on the side of the pin 3, which are preferably designed such that a tangent to the bottoms of both grooves or grooves 5 extended plane is offset to the right in the drawing relative to a plane containing the axis of the pin 3 and extending in the ski transverse direction when the shoe or sole holder 4 assumes its normal or central position as shown.
  • a bore 6 Arranged within the housing 2 is a bore 6 which extends in the longitudinal direction of the ski and which has a cylindrical section 6 ′ with a constant cross section at its left end in the drawing. This is followed on the right by a section 6 ′′ which, at least in the direction of the ski, widens conically toward the shoe or sole holder 4.
  • the bore 6 is open to the shoe or sole holder 4.
  • a flange-like collar 7 is formed on the housing 2, which annularly surrounds a central opening.
  • the head of an adjusting screw 8 projects through this central opening and has an annular web formed on the screw head on the inside of the collar, which can rest or support on the inside of the collar 7 in the manner shown.
  • a threaded sleeve 9 On the threaded part of the adjusting screw 8 a threaded sleeve 9 is arranged, which has a flange 9 ', which engages with a radial extension (not shown) in an axial groove in the wall of the bore 6 (not visible in the drawing) and thus screw-adjustable on the threaded section of the adjusting screw 8, but relative to the housing 2 is held non-rotatably. If the adjusting screw 8 is rotated relative to the housing 2 by means of a screwdriver, the threaded sleeve 9 moves in the axial direction of the adjusting screw 8 relative to the housing 2.
  • the threaded sleeve 9 or its flange 9 ' serve as a housing-side abutment for one end of a helical compression spring 10, the other end of which is stretched against the bottom of a hollow piston 11 which is arranged in the bore 6.
  • the piston 11 has a sufficient axial length, such that the piston end facing away from the shoe or sole holder 4 projects into the section 6 'of the bore 6 when the piston 11 - as shown - with web-like lasts 12 molded onto it in normal - or middle position of the shoe or sole holder 4 rests on the bottoms of both grooves or grooves 5 of the shoe or sole holder 4.
  • the cross section of the piston 11 is adapted to the cross section of the section 6 'of the bore 6, at least in the cross-ski direction, such that the left end of the piston 11 in the drawing in the section 6' is guided practically without play in the cross-ski direction.
  • the right end of the drawing is Piston 11 movable in the ski transverse direction, the piston 11 executing a pivoting movement about a vertical ski axis passing through the other piston end when its right end moves in the ski transverse direction.
  • the binding shown works as follows: Depending on the axial setting of the threaded sleeve 9 on the threaded part of the adjusting screw 8, the helical compression spring 10 has a more or less large preload with which the piston 11 in the illustrated normal or central position of the shoe or sole holder 4 against the shoe or Sole holder 4 tensioned and the grooves or grooves 5 and the web-shaped lasts 12 are held in mutual engagement.
  • the bias of the helical compression spring 10 is sufficient to keep the piston 11 rigid relative to the shoe or sole holder 4, i.e. Shoe or sole holder 4 and piston 11 remain immovable relative to one another and form a jointly movable unit.
  • the shoe or sole holder 4 executes a pivoting movement with respect to the axis of the pin 3, in each case one of the web-like strips 12 of the piston 11 emerges from the associated groove or groove 5 of the shoe or sole holder 4, while the respective other strip 12 remains in engagement with the groove or groove 5 assigned to it.
  • the piston 11 is inserted into the bore 6 with increasing compression of the helical compression spring 10.
  • the groove or groove 5 which remains in engagement with the associated last 12 practically runs through an arc path which practically guides the associated last 12 and thus the end of the piston 11 facing the shoe or sole holder 4 are able to follow without constraint, because the right end of the piston 11 can move sufficiently transversely due to the taper of the section 6 ′′ of the bore 6, at least within a limited pivoting range of the shoe or sole holder 4 that forms the elasticity range of the binding.
  • the shoe or sole holder 4 If the shoe or sole holder 4 is pivoted to a limited extent, the end of the ski shoe or the shoe sole held by the same is not yet released. Rather, the shoe or sole holder 4 can return the ski boot to the normal or central position when pivoted back by the spring-loaded piston 11.
  • the entire bore 6 is cylindrical with a constant cross section and for the piston 11 to be tapered with a taper in the direction of the shoe or sole holder 4 in order to enable the desired transverse mobility of the right piston end while at the same time ensuring that the other piston end is guided free of play in the direction of the ski.
  • lasts 12 can be arranged on the shoe or sole holder 4 and the grooves or grooves 5 on the piston 4.
  • shoe or sole holder 4 can additionally be arranged so as to be pivotable about a transverse axis in order, if necessary, to enable the ski boot to be released upwards by pivoting about this axis - without any pivoting about an axis parallel to the ski vertical axis.
  • the binding shown can also be used to hold the heel or the heel of a ski boot.
