Definitions

  • the invention relates to a heel hold-down device with a base plate that can be fastened to the ski or guided in a guide rail in the longitudinal direction of the ski, and a base block arranged on it and essentially U-shaped in cross-section, in the upper area of which a unit consisting of a sole hold-down device and a step spur surrounds Axle stub is pivotally mounted and in its preferably lower area removed from the stub axles, a control lever interposed between a pressure element acted upon by a detent spring and the unit is arranged, to which an intermediate lever is assigned, which is pivotally mounted in the unit on an axis.
  • Such heel hold-down devices are described in FIGS. 3 and 5 of DE-OS 26 28 748.
  • the known designs had the advantage that the force required for arbitrary release was very low (in one version only the friction of the release lever had to be overcome and in the other the load spring of a ball lock was compressed), but they had the disadvantage that the Getting in the ski boot in the first version had to overcome the full pressure of the detent spring and that in the second version the ball lock only came into operation when the unit consisting of the sole retainer and the step spur moved upwards.
  • the ball lock was not able to cope with the rough stresses that occur when skiing because the lock ball could easily be blocked by dirt and the function of the heel hold-down was put in question.
  • the aim of the invention is to eliminate the disadvantages of the known designs and to create a heel hold-down device of the type outlined at the outset, by means of which, on the one hand, proper involuntary triggering in the conventional sense and, on the other hand, a much easier entry of the ski boot into the heel hold-down device compared to the known embodiments becomes.
  • the intermediate lever is under the influence of a spring which is substantially weaker than the catch spring, preferably a compression spring, and has an arcuate branch of a control cam on its side remote from the pivot axis, on which in the event of an involuntary triggering the control lug of the control lever is guided, the tangential plane through the respective point of contact between the intermediate lever and the control lever on the control curve with a tagential plane through the point of contact at a circular cylinder running through the point of contact about the pivot axis of the intermediate lever including an angle that is less than is the angle of friction between the materials of the two levers.
  • a spring which is substantially weaker than the catch spring, preferably a compression spring, and has an arcuate branch of a control cam on its side remote from the pivot axis, on which in the event of an involuntary triggering the control lug of the control lever is guided, the tangential plane through the respective point of contact between the intermediate lever and the control lever on the control curve with a tagential plane through the point of
  • the intermediate lever is pivoted away against the force of the weak spring when entering the ski boot in the heel hold-down device, so that the control lever is only acted on to a reduced extent by the sole hold-down device.
  • This also compresses the detent spring to a lesser extent, which considerably reduces the force required to get the ski boot on.
  • another feature of the invention aims that the other branch of the control cam of the intermediate lever in its depressed position extends at least approximately coaxially to the two stub axles or tangentially to a cylinder, the axis of which passes through the two stub axles.
  • the intermediate lever is designed as a two-armed lever, on the lower arm of which is free of a control curve, a nose of the control lever rests in the driving position of the heel hold-down device .
  • the invention further provides that the unit consisting of sole hold-down device and step spur has a recess for the intermediate lever on the side of the same which is distant from the pivot axis and projects towards the control member. This area considerably reduces the area in which the control element touches the intermediate lever.
  • the intermediate lever according to the invention has one or more grooves into which tooth-like projections of the edge of the unit protrude. Furthermore, it has proven to be advantageous if the intermediate lever, in its area distant from the pivot axis, is parallel to the pivot axis Penetrates the edge and in this way limits the pivot angle of the intermediate lever.
  • FIG.l is a longitudinal section through a first embodiment in the driving position and Fig.2 in the boarding position.
  • 3 and 4 show analog sections through a second embodiment.
  • 3a shows a detail of FIG. 3 on a larger scale with the forces acting between the control lever and the intermediate lever, and
  • FIG. 3a shows an associated force plan.
  • 5 and 6 illustrate a section through a third embodiment in the driving position and a detail of this embodiment.
  • 7 and 8 show sections through a fourth embodiment in the driving position and in the boarding position.
  • FIGS. 9-12 show a fifth embodiment in the driving position, during the involuntary triggering process, in the open state and during the boarding process. Since this heel hold-down largely corresponds to the previous ones in its construction, only the parts essential for the control have been shown here.
  • the heel hold-down device shown in FIGS. 1 and 2 has a base plate 1 to which a bearing block 2 which is essentially U-shaped in cross section is fastened.
  • a bearing block 2 which is essentially U-shaped in cross section is fastened.
  • two stub axles 3 are arranged, around which, on the one hand, a spring housing 4 for the detent spring 5, which acts on a pressure member 6, and on the other hand, a unit 9 consisting of the sole hold-down 7 and the step spur 8 is pivotably mounted independently of one another are.
  • a control lever 11 is rotatably arranged in the lower region of the legs of the bearing block 2 in the lower region of the legs of the bearing block 2 there is an axis 10 on which a control lever 11 is rotatably arranged. This protrudes into the space between the pressure member 6 and the unit 9.
  • a recess 12 in which a two-armed intermediate lever 13 about an axis 14 is pivotally mounted.
  • a compression spring 15 or the like In the recess 12 there is also a compression spring 15 or the like. (This can also be formed by a rubber plug), one end of which is supported on the unit 9 and the other end of which is supported on the intermediate lever 13.
  • the control lever 11 carries a control nose 11a on the side facing the unit 9, which in the event of an involuntary release of the heel hold-down device, e.g. in the event of a frontal fall, slides along the inside of the unit 9 or along one arm 13a of the intermediate lever 13.
  • the arm 13a On its side facing the control lever 11, the arm 13a carries a control curve, of which the branch 13c in its end region forms an angle with the control nose 11a of the control lever 11 which is smaller than the friction angle between the control lever and the intermediate lever 13.
  • the other branch 13d of the control curve runs approximately parallel to a vertical plane through the axis 14 of the intermediate lever 13.
  • the control lever 11 has on the side facing the pressure member 6 a projection 11b, on which the pressure member rests.
  • the control lever 11 carries at its lower end a nose 11c which, in the driving position, bears on the second arm 13b of the intermediate lever 13.
  • this nose 11c causes the intermediate lever 13 initially to remain in the position raised from the bottom of the recess 12, in which the full force of the detent spring 5 acts on the unit 9.
  • This position is further maintained in that, due to the magnitude of the angle between the control lug Ila of the control lever 11 and the branch 13c of the control cam of the intermediate lever 13, the arm 13a of the friction lever is pulled out of the recess by the friction.
  • FIG. 3 and 4 The embodiment shown in Figures 3 and 4 is similar to that described first. It differs from this only in that a rubber spring 15 'is accommodated in the recess 12 instead of a helical compression spring 15 and that the axis 14' is not located at the lower end of the recess 12, but rather in its central region.
  • the function of this embodiment corresponds to the function of the heel downholder described first.
  • a tangential plane also goes to curve 13c.
  • This tangential plane is designated t l in FIG. 3b.
  • the component P n of the force P normal to the tangential plane encloses an angle ⁇ with the latter.
  • This component P n is therefore P.cos ⁇ .
  • the other component P t is effective in the tangential plane t 1 and is P.sin ⁇ .
  • the normal component P n causes a frictional force (sliding resistance) which is opposite to the tangential component and is ⁇ .P.cos ⁇ .
  • ⁇ is the coefficient of friction.
  • a second tangential plane t 2 is drawn through the point of contact A, which is placed on a circular cylinder running through the point of contact A about the pivot axis 14 of the intermediate lever 13 and includes an angle ⁇ with the tangential plane t 1 that is smaller than is the angle of friction f between the materials of the two levers 11 and 13.
  • the designer has the option of changing the Course of the control curve 13c and / or to bring about the function of the heel hold-down according to the invention by selecting the materials sliding on one another.
  • the unit 9 'consisting of sole hold-down device 7 and step spur 8 has a recess 12' for the intermediate lever 13 'on the side of the recess which is distant from the pivot axis 14, against the control lever 11 projecting edge 16.
  • this edge 16 which contributes to considerable protection of the intermediate lever 13 'and of its pivot axis 14, - seen in section - would run in a wedge shape, which entails strength problems.
  • the intermediate lever 13 ' is provided in its upper region with one or more grooves 13'a, into which projections 16a of the edge 16 protrude tooth-like.
  • the intermediate lever 13 ' is under the influence of a helical compression spring 15, which tries to push it out of the recess 12'.
  • the intermediate lever 13 ' is penetrated in its upper region by a bolt 17 which is guided in arcuate slots 18 in the projections 16a of the edge 16.
  • This function essentially does not change the function of the heel hold-down device.
  • the only difference compared to the first two versions lies in the fact that only part of the branch 13c of the control curve of the intermediate lever 13 'is used to control the heel hold-down device in the event of an involuntary release, since the predominant area of this branch is covered by the edge 16 and therefore does not function.
  • FIGS. 7 and 8 Another embodiment for a heel hold-down device according to the invention is shown in FIGS. 7 and 8.
  • the intermediate lever is designed as an angle lever 13 ", one leg 13a” in the driving position in the recess 12 of the unit 9 "and the other leg 13b” has a shoulder 19 or a V-shaped recess at its free end, into which one involuntary triggering of the heel retainer a pin 20, which is attached to the upper end of the control member 11 ", engages.
  • control member 11 slides "with its control nose 11a" along the inside of the unit 9 ", which carries a control cam here. In this case, the force of the detent spring 5 is fully effective. However, if the end position of the unit 9" is, in which it is in the highest position, the pin 20 of the control member 11 "enters the recess or the shoulder 19 of the leg 13b".
  • the intermediate lever 13 "' in contrast to the previous embodiments, is designed as a one-armed lever which can be pivoted about an axis 14 in a recess 12 of the unit 9"'.
  • the intermediate lever 13 "'on the side facing the control member 11"' has on the one hand a projection 13a "'and on the other hand a recess 13b"', which elements have a recess 11a "'and a projection 11b"' on the control element 11 "'.
  • the two recesses and projections work together in the manner of a joint.
  • the control element 13'" adjoins the recess 13b "" in the direction of the ski boot.
  • the control element 11 "" also has a second recess 11 c '''.
  • this heel hold-down device is as follows: in the driving position, the two projections 13a "'and 11b"' lie in the associated recesses 11a “'and 13b”'. If an involuntary release of the heel hold-down device is initiated, the intermediate lever 13 '"is pivoted clockwise. This pushes the control member 11"' back against the action of the detent spring 5, which acts directly on the control member. As soon as a certain angular position of the intermediate lever 13 "'is reached, the control cam 13c'" lifts the two projections 13a "'and 11b”' from the associated recesses 11a "'and 13b”', so that the articulated connection of the intermediate lever 13 "' with the control member 11 "'is released. The projection 13a "'is received by the second recess 11c"'. In this position, the heel hold-down is ready to start the ski boot.
  • the intermediate lever 13 "'is pivoted counterclockwise against the bottom of the recess 12 in the unit 9"'.
  • the projection 13a "'of the intermediate lever 13” "leaves the recess 11c"' of the control member 11 '"and the projection 11a"' of which rests against the rear of the intermediate lever.
  • the two projections arrive 13a "'and 11b"' in engagement with the associated recesses 11a "'and 13b"'.
  • the invention is not tied to the exemplary embodiments described above and shown in the drawing. Rather, various modifications thereof are possible without leaving the scope of the invention.
  • the Pivot axis for the control lever can also be arranged in the upper area of the substantially U-shaped bearing block instead of in the vicinity of the base plate.
