Definitions

  • the invention relates to a toe piece according to the preamble of claim 1.
  • Such a toe is already described in AT-PS 347 310.
  • a stop is attached to the base plate with a guide piece, which is equipped with an oblique guide track.
  • the control body is pressed downward by this guideway when one of the two angle levers is pivoted out when the skier loses his or her turn.
  • the engagement of the swiveled-out angle lever with the control body is released, whereupon the control body returns to the starting position by the force of the release spring.
  • the deflected angle lever is returned by means of a support plate which is acted upon by the release spring and an additional leaf spring.
  • This embodiment has the disadvantage that regardless of whether the triggering is by a pure lintel or by a lintel combined with a frontal lintel, the work required for pivoting the bell crank is always constant.
  • the front end of the ski boot is held in place by a holding shell, which is supported at three points on the housing under the influence of a release spring.
  • a lateral triggering of the toe piece is made possible both in the event of a turning fall and in the event of a backward fall of the skier, the toe piece is released upwards.
  • the sole of the ski boot must correspond exactly to the norm and fit in the holding shell.
  • the sole is too small, the ski boot in the holding shell will wobble while driving, which is undesirable. If the sole is too large, however, the holding shell will only touch the sole along two lines, which inevitably can lead to damage to the sole.
  • DE-OS 29 05 837 describes a toe piece in which a release spring is preloaded when the weight of the skier is shifted forward using a pedal, an actuating rod and a control gear.
  • a release spring is preloaded when the weight of the skier is shifted forward using a pedal, an actuating rod and a control gear.
  • the work to be done by the shell-like sole holder is therefore reduced before the sole holder begins its pivoting process.
  • this toe piece is complicated in its construction.
  • the front jaw according to DE-OS 20 30 749 differs from the previously discussed embodiments in that the jaw body can be pivoted about an axis running perpendicular to the top of the ski.
  • the adjustable release spring which acts on a locking ball, is housed in a hole parallel to the swivel axis.
  • the locking ball lies in a longitudinally extending and wedge-shaped narrowing recess in a slidably mounted guide plate to which a toothed rack is fastened, in which a toothed segment engages.
  • the latter has a lever arm that can be depressed by the ski boot in the event of a frontal fall of the skier.
  • the guide plate is first shifted towards the end of the ski, so that the locking ball is supported in the narrowed area.
  • this reduces the force required for triggering, and the cup-shaped sole hold-down, which is fastened to the jaw body, can be pivoted with a lower force than in the case of a pure lintel.
  • This front jaw also has numerous components which make its manufacture more difficult.
  • the control body has on its front side two webs which are arranged one above the other and have different widths with correspondingly designed control surfaces.
  • the two angle levers rest on differently designed control surfaces of the individual webs, the control body experiencing a vertical displacement.
  • the toe piece is released according to two different characteristics.
  • free movement of the drawbar in the vertical plane is required for the vertical displacement of the control body.
  • the pull rod is pivotally mounted in the housing and guided in an elongated hole in the transverse wall.
  • FR-PS 2 624 386 is also mentioned, in which, however, in all embodiments a one-armed pedal is disclosed which is equipped with a two-armed rocker arm referred to as "basculeur 17" (cf. FIGS. 4 and 9) cooperates.
  • basicculeur 17 a two-armed rocker arm
  • two components namely the one-armed pedal and the two-armed rocker arm, are actually required for the power transmission from the ski boot to the toe pieces.
  • the situation is similar with regard to a one-armed pedal with a rocker arm in the solution known from DE-OS 39 37 363.
  • the invention has for its object to eliminate the disadvantages of the known embodiments and to provide a toe piece in which the reduction of the work of swiveling out required in a forward turning fall is maintained without compression of the release spring, but the design of the control element can be simplified. Furthermore, the preload of the release spring should also be constant here, regardless of whether it is a pure lintel or a lintel combined with a frontal lintel.
  • control body is arranged on the actuation pedal and is operatively connected to two control members, which in turn are mounted to be pivotable to a limited extent between three support surfaces, ensures that the increased spring force is compensated for in a simpler manner than was possible in the prior art.
  • the use of a pedal designed as a two-armed lever further simplifies the overall construction.
  • the features of claim 2 determine the support surfaces on which the individual control elements are supported.
  • the changed position of the support members is characterized by the features of claim 3.
  • the features of claim 4 serve to determine the compensation of the increased spring force.
  • the features of claim 5 include a particularly favorable arrangement of the individual control elements.
  • the measure according to the invention is also protected in the case of a front jaw with a non-automatic sole hold-down device.
  • Figures 1 to 4 a first embodiment of a toe piece according to the invention, wherein Figures 1 and 2 show the toe piece in the rest position (driving position) in longitudinal central section or in plan view and partly in section along the line II-II in Fig.1 .
  • Figures 3 and 4 show the front jaws in a similar representation as that Figures 1 and 2, but in a forward turn.
  • Figure 5 is similar to Figure 1, but with an extended function for a reverse turn.
  • the Fig.6 is a similar representation as Fig.1, but with a manually adjustable sole hold-down, for forward and backward lintels.
  • the front jaw is designated 1 in its entirety.
  • the front jaw 1 has a housing 2, which is fixed in a known manner on the top of a ski 3 by means of only indicated fastening screws 4.
  • a bore 2b is recessed in the housing 2, in which a release spring 5 designed as a helical spring is accommodated.
  • the trigger spring 5 is supported at one end on a transverse wall 2c of the housing 2 and at its other end on a spring plate 6, which is guided in the bore 2b adjustable by means of a threaded sleeve 7 in the direction of the axis of the trigger spring 5.
  • the threaded sleeve 7 is screwed onto a pull rod 8, which passes through the release spring 5 in the center, protrudes through a bore 2d in the transverse wall 2c of the housing 2 and carries a control plate 9 at its rear end.
  • the control plate 9 is provided with a display 9a which can be moved longitudinally below a window in a manner known per se and which indicates the respectively set spring force by means of a scale (not shown).
  • a vertically extending adjusting pin 16 is provided for a sole hold-down device 17, the latter being always pushed towards the base of the housing 2 by a compression spring 18.
  • a pedal 12 articulated on an axis 13 with an elongated hole 12a is attached below the sole hold-down device 17 and in the lower section of the adjusting bolt 16.
  • the pedal 12 is designed as a two-armed lever, the axis 13 of the pedal 12 running at a distance behind the front jaw 1 transversely to its longitudinal axis.
  • a transverse plane which lies between the longitudinal axis of the adjusting bolt 16 and the control plate 9, are located in the housing 2, symmetrically to the vertical longitudinal center plane of the Front jaw 1, two vertical axes 10, on which angle levers 11 are mounted (see Fig. 2).
  • These angle levers 11 rest with their shorter angle lever arms 11a, each with the interposition of a control element 20, on the front of the control plate 9 and with their longer lever arms 11b against a ski boot 21, which is only indicated in FIG.
  • a control body 19 is arranged on the end section of the pedal 11 facing the control plate 9, the configuration of which will be discussed later.
  • the two control members 20 are arranged on the angle levers 11 symmetrically to the vertical longitudinal center plane of the front jaw 1. They are supported on surface sections of the control body 19, the shorter lever arms 11a of the angle lever 11 and on their axes 10. Each control member 20 is held in position in the travel position, as shown in FIGS. 1 and 2, by the force of the release spring 5 via the control plate 9.
  • FIG. 5 shows a front jaw 1 ', which is also suitable for compensating the torque to be overcome in the event of a reverse turning fall.
  • a force is exerted by the ski boot, not shown, in the direction of arrow P2 on the sole hold-down device 17 '.
  • This is now pushed up from its seat originally occupied on the pedal 12 'against the force of the compression spring 18' along the shaft of the adjusting bolt 16 '.
  • the pull rod 8 ', release lever 5' and release plate 9 ' remain in their original position according to FIG. 1 until the compression spring 18' is compressed to the stop.
  • control pin 16 ' The upper section of the control pin 16 'is guided in an elongated hole 22'a of a holding member 22' which is pivotally mounted on the housing 2 'about a transverse axis 23'.
  • the adjusting bolt 16 ' pulls the pedal 12' with the control body 19 ', whereby the balancing of the torques takes place in the manner already described with reference to FIGS. 3 and 4.
  • a screw bolt 16 ′′ is provided as an adjusting bolt for adjusting the height of the sole hold-down device 17 ′′.
  • the other parts of the toe piece 1 ′′ correspond to those of the first exemplary embodiment according to FIGS. 1 to 4 (analogously without the compression spring 18).
  • the adjustment of such a sole hold-down device 17 ′′ by means of a screw bolt 16 ′′ is known per se and does not form the subject of the present invention.
  • the procedure is the same for a forward turn that of the type described in FIGS. 3 and 4 and for a reverse turn that of FIG. 5, so that these details will not be discussed further.
  • the axis 13 of the pedal 12 is on a section 2e, 2'e, 2''e pointing backwards of the housing 2.2 ', 2''mounted.
  • the arrangement of the individual control members 20, 20 ', 20''in the associated angle lever 11, 11', 11 '' is such that each control member 20, 20 ', 20''is seen in cross section between the lower and the upper boundary wall U is open to limited use in the direction of the shoe 21.
  • the limit of freedom of movement is determined by the support surfaces described at the beginning for the individual control elements. It can be seen from the comparison of FIG. 4 with FIG.
  • FIGS. 4 and 2 show the change in the arrangement of the adjoining section of the control element 20 on the vertical axis 10 and on the control surface 19a of the control body 19.
  • the design of such control surfaces (19a) is known, for example, from the prior art mentioned at the outset (see EP-A2-0415 006, FIG. 5).
