Definitions

  • the invention relates to a heel tensioner for safety ski bindings with a spring-loaded, as an obtuse angle thrust member for the heel of the boot, which is pivotally and displaceably mounted by means of a pivot axis extending transversely to the longitudinal axis of the ski relative to a bracket, which is directly or indirectly on the ski is arranged, the thrust member is secured in the tensioned position relative to the bracket by a coupling which is pivotally mounted on the thrust member and cooperates with the bracket or a part connected thereto in the coupled position in which it is held by spring action, and which after the uncoupling allows a free pivotability of the thrust member relative to the bracket about the pivot axis, the first lever arm extending between the pivot axis and the support point of the thrust member on the heel serves as a sole hold-down and is essentially formed by one leg of the angle, un d wherein the coupling associated with the thrust member is arranged on the second lever arm, which is essentially through the other leg of the angle is formed.
  • the object of the invention is to design the coupling so that a comfortable arbitrary uncoupling is possible, for example, by actuation by means of the ski pole or by stepping on it by means of the ski boot, without the risk of unwanted decoupling.
  • This configuration enables two types of arbitrary decoupling.
  • the first possibility is that the actuator slides along the slope of the thrust member by exerting pressure from above, for example through a ski pole or through the ski boot, and thereby causes the coupling to pivot relative to the thrust member, with the result that the coupling of the bracket is released.
  • the second possibility of actuation is that the actuator is pivoted upward by hand, which creates a handle with which the coupling can be pivoted about its pivot axis against the spring action from the coupling position.
  • the pivot axis of the actuating member is provided in the area of the clutch facing away from the sole holder and this actuating member is designed as a one-armed lever, it is located in the area of the pushing member since it must cooperate with the slope on the pushing member so that it does not protrude to the rear. This avoids the risk of unwanted tripping.
  • a particularly preferred embodiment of the invention is that the coupling has a substantially U-shaped base part, which is pivotally mounted with its free ends on the thrust member and interacts with the bracket with its base part, that on the legs of the U-shaped base part above, the thrust member between receiving cheeks are arranged, that at the upper ends of the cheeks the actuating member is pivotally mounted, which is designed as a flap and that the slope is formed at the upper end of the thrust member. If, in a further advantageous embodiment of the actuating member, covers the upper open end of the thrust member, the side walls of which are formed as an incline at their upper edges, a coupling is created which fits the upper end of the thrust member with the exception of the base part, which cooperates with the bracket, closely surrounds.
  • the coupling can have a cross bar connecting the two cheeks at the upper ends of the cheeks, which is in the coupling position as a limit stop for the coupling on the thrust member.
  • This not only increases the stability of the coupling and limits its swivel range in the direction of the bracket, but this crossbar can also be used in a wider range advantageous embodiment serve as a stop for the actuator when it is used as a handle for decoupling by hand.
  • the actuating member can have a detent depression for the use of a ski pole. Additionally or alternatively, in a further embodiment, the actuating member can be provided on its upper side with an uneven, preferably corrugated surface. This uneven surface is intended to prevent the ski boot from sliding off when the actuator is pressed down.
  • an extension is formed on the lower side of the actuating member facing the slant on the pushing member with an inclined sliding surface which is adapted to the angle of inclination of the slope is.
  • the heel tensioner shown in the drawing comprises a bracket 1 which is pivotally mounted in bearing eyes 2 about an axis 3 lying transversely to the longitudinal direction of the ski, the bearing eyes 2 being attached either to the ski or to a touring plate or a touring frame.
  • the bracket 1 has V-shaped legs 4, 4 ', which merge into a U-shaped part, the legs with 5, 5' and the transverse web is designated 6.
  • the bracket 1 is bent forward, ie in the direction of the ski boot by about 45 °.
  • a pivot axis 7 is provided, which is firmly connected to the legs 5, 5 '.
  • the pivot axis 7 is used to support a thrust member 8 which is designed as a two-armed angle lever 9, 10, the individual arms 9, 10 enclosing an angle with one another which is greater than 90 °.
  • the thrust member 8 is in the area of the longer arm 10 as an after Bottom open sleeve-like housing 11 which receives a compression spring 12 which is held between two spring plates 13, 14 and is penetrated by a clamping screw 15 which is supported with its head 16 on the upper spring plate 14 and screwed into a threaded tension member 17 which is attached to the pivot axis 7.
  • the lower spring plate is supported on an inwardly projecting shoulder 18 of the housing 11.
  • downwardly open guide slots 19 are provided in the longitudinal direction of the housing 11, with which the housing 11 is plugged onto the pivot axis 7. These guide slots 19 not only allow pivoting of the thrust member 8, but also a displacement of the thrust member 8 against the action of the spring 12 for the purpose of triggering the spring tensioner in the event of an overload.
  • a pivot axis 20 is provided, about which a coupling, designated overall by 21, is pivotably mounted.
  • the coupling 21 has an essentially U-shaped base part 22, which is mounted with its free ends on the thrust member 8 so as to be pivotable about the axis 20.
  • the legs of the base part 22 protrude beyond the thrust member in the direction of the sole holder and are bent downward in the region projecting beyond the thrust member, as a result of which the two Leg of the base part 22 connecting base part 23 can overlap the cross bar 6 of the bracket 1.
  • the legs of the base part 22 are at a greater distance from one another than this corresponds to the width of the bracket 1 in the region of the transverse web 6.
  • two side cheeks 24 and 25 are made in one piece, which together with the base 22 accommodate the thrust member 8 between them.
  • a cross bar 26 connecting the cheeks 24 and 25 serves as a limit stop for the clutch 21, which is loaded by a hairpin-shaped spring 27 in the sense that the cross bar 26 serving as a limit stop is pressed against the housing 11, as a result of which the base part 23 of the base part 22 always occupies the same position with respect to the thrust member 8 when the base part 23 is engaged on the crosspiece 6 of the bracket 1.
  • the spring 27 is accommodated in a recess 28 of the housing 11 and is held on the cheek 25 on one of its two legs by means of a pivot axis 35.
  • the other free leg is supported on the thrust member 8 within the recess 28.
  • an actuator 29 designed as a cap pivoted about an axis 30 which is supported by the cheeks 24 and 25.
  • a spring 31 is wound around the axis 30, one end 32 of which is supported on the cross bar 26, while the other end 33 engages in an opening 34 of the actuating member 29 and loads it downward.
  • the actuator 29 covers the housing 11, which is open at the top, and has on its underside an extension 36, which is provided with a lower inclined sliding surface 37, which is formed on a slope formed on the upper edges of the housing 11 38 rests.
  • the coupling 21 is hooked and coupled to the bracket 1
  • the inner end of the sliding surface 37 lies on the outer end of the bevel 38.
  • a recess 39 is provided for the use of a ski pole for pressing the actuator 29 in the direction of arrow 40. Furthermore, the surface 41 of the actuating member is designed to be grooved in order to prevent the ski boot from slipping off when the actuating member 29 is pressed down by means of one.
  • the cross bar 26 also serves as a stop for the actuator 29 when it is pivoted up in the direction of the arrow 42.
  • the thrust member 8 is pushed upwards with compression of the spring 12, the housing 11 being displaced with respect to the pivot axis 7 due to the arrangement of the guide slots 19. If a certain displacement path is achieved due to a corresponding force that is greater than this corresponds to the overlap of the base part 23 on the cross bar 6 of the bracket 1, the base part 23 comes free from the cross bar 6 and the thrust member 8 can pivot about the pivot axis 7, whereby the Boots released from the heel strap.
  • the actuator 29 can be pivoted in the direction of arrow 42 against the action of the spring 31 until it abuts the cross bar 26.
  • the actuating member 29 forms a handle in order to pivot the coupling, designated overall by 21, about the pivot axis 20 against the action of the spring 27.
  • the base part 23 is released from the crosspiece 6 of the bracket 1, as a result of which the thrust member 8 can be pivoted about the pivot axis 7.
  • the shorter arm 9 of the thrust member 8 serving as the sole holder is released from the boot.
  • a force is applied to the actuating member 29 in the direction of arrow 40 by means of a ski stick or a ski boot.
  • the sliding surface 37 of the actuating member 29 slides on the bevel 38 of the thrust member 8, as a result of which the coupling 21 is pivoted rearward about the pivot axis 20, which likewise leads to the base part 23 being released from the transverse web 6.
  • the bracket 1 can also be arranged firmly on the ski. In this case, a height adjustment of the thrust member is required so that it can be adapted to the different heel heights of the ski boot.
  • the actuator 29 can be made of a plastic that has particularly favorable sliding properties, so that this favors the opening process shown in FIG. 6, in which the sliding surface 37 of the actuator 29 slides on the slope 38 of the thrust member.
