Definitions

  • the invention relates to a locking device according to the preamble of claim 1.
  • Sole hold-downs have the task of holding a ski boot on a ski binding or on a ski during the descent or releasing a ski boot in the event of a fall that is dangerous for the runner.
  • the sole hold-down devices are mounted on the ski binding and are either acted upon directly by a latching mechanism or act via a control cam against a latching rocker or the like, which is acted upon by a release spring.
  • a binding with sole hold-downs that absorb both lateral and vertical forces is described in AT-PS 376.895, in which a control rod is designed as a push rod, which in turn, under certain circumstances, e.g. bie larger lengths require a stronger dimensioning of the control rod than would have to be the case with a tensile load.
  • the object of the invention is to provide a locking device in which the forces are absorbed by components which are as wear-resistant as possible and in which as little friction as possible occurs between the parts which interact with one another, as a result of which the above disadvantages should be avoided. Furthermore, a compact design is to be made possible and the main holding forces are transmitted through tensile stress.
  • the control slot has a cam or the like on its one guide surface. and on its other guide surface a recess, the width of which is tapered in the driving position by the locking member.
  • the locking member thus prevents the sole holding-down device from opening, while the main tensile force transmitted from the sole holding-down device to the other binding parts is initially caused by the cam or the like. in that part of the ski collar that also holds the sole hold-down and is therefore extremely robust due to its construction.
  • the control slot has a cranked shape over its length, the one guide surface on the side facing the sole retainer having a bulge and the other guide surface on the side facing the sole retainer having an opposite recess.
  • the offset of the position of the end region or the control rod and thus the standby or departure position of the binding is defined.
  • the control slot is simple and, in cooperation with the locking member, can optimally absorb even the highest tensile forces of the sole hold-down device.
  • the end region of the control rod is provided with an integrally formed or rigidly fastened fitting piece which is guided in the control slot, as a result of which Game between the end area and the control slot is kept very low and therefore the sole hold-down or the hold-down hold the ski boot in the driving position with a steady force and with constant force.
  • the fitting piece is designed as a profile bolt with a prallelogram-like outline and preferably rounded corners.
  • the adapter is designed as a roller.
  • the locking member is designed in the form of a pawl, pivotably mounted on the ski binding part and acted upon by an engagement part which transmits a release function movement of the binding.
  • all moving parts that are directly responsible for triggering the sole hold-down device are thus advantageously stored in a single ski binding part, as a result of which it is compact and an undesirable relative play between these components is avoided even during the toughest operation.
  • a particular field of application of the invention results for a center-point binding with a sole plate pivotable about a vertical bolt with a torsion measuring and control mechanism in the sole plate and with a pivotable heel-side tread plate with two sole hold-downs, which absorb both the vertical and horizontal forces.
  • Hiebei are after further training Invention the sole retainer articulated on the tread plate, the attacking part being controlled by the torsion measuring and control mechanism.
  • a safe functional solution has been found, by means of which two trigger mechanisms, which are separate per se, are coupled to one another, namely for vertical and lateral triggering, via the locking member.
  • FIG. 1 to 4 show a tread plate of a center-point binding partially cut with an integrated control slot
  • Fig.l shows a tread plate 11 partially cut, as used for example in a center binding for the heel area.
  • the tread plate 11 is a robust component which is essentially made of one piece and which is mounted, for example, by means of a transverse axis 12 (FIGS. 3 and 4) on a rotatable plate of the center point binding, not shown.
  • the tread plate 11 has lateral tabs 13 which carry two opposing sole hold-down devices 1 via bearing pins 14.
  • the tread plate 11 is constructed symmetrically over the vertical center plane on the upper side 15 of the ski.
  • the sole hold-down devices 1 are shown in the figure approximately perpendicular to the top of the tread plate 11 in the driving position.
  • the sole hold-down 1 encompass opposing points of attack on a ski boot, not shown, by means of lateral surfaces 16, transverse surfaces 17 to the longitudinal direction of the ski and hold-down surfaces 19 which extend approximately parallel to the top of the tread plate 11.
  • the ski boot, not shown, is thus held pressed sideways in the driving position, in the longitudinal direction of the ski and to the top of the tread plate.
  • the individual sole hold-down devices 1 each have a control rod 2 which is hinged at one end to the sole holding-down device 1 via a further bearing journal 20 and carries a profile bolt 10 with a parollelogram-like outline at its end region 3 facing away from the sole holding-down device 1, locked by the profile pin 10 being held in a cranked control slot 4 on the crank by a locking member 5.
  • the cranking of the control slot 4 forms a bulge 18 to overcome which the profile bolt 10 should slide upwards. However, this sliding afterwards is prevented by the locking member 5, in that the locking member 5 engages between the top of the profiled bolt 10 and the guide surface 7 of the control slot 4.
  • the recess 8 of the other guide surface 7, which is the same as the bulge 18 of the one guide surface 6, thus offers a recess for the profiled bolt 10, provided that the locking member 5 is not in engagement.
  • the profiled bolt 10 can be guided through the control rod 2 along the one guide surface 6 of the control slot 4 and overcome the bulge 18, as a result of which Shoe, not shown, is released from engagement with the sole hold-down 1.
  • the profiled bolt 10 also briefly slides on the other guide surface 7. Instead of the profiled bolt 10, a roller could also be provided.
  • the sectional side view of a tread plate 11 according to FIG. 3 also shows the driving position with locked sole hold-down devices 1.
  • the locking member 5 is designed as a pawl and is pivotably mounted on the tread plate 11 via a pivot bearing 21.
  • the locking member 5 engages between the profile bolt 10 and the guide surface 6 of the control slot 4.
  • the profile bolt 10 is rigidly connected to the control rod 2, for example by a press fit, in a bore 22 in the end region 3 thereof.
  • the pivoting movement of the locking member 5 is by an engagement part 9 brought about, which engages around the locking member 5 and causes a torsion of the plate, not shown, of the center link by means of the torsion measuring and control mechanism, which is integrated in the plate and is also not shown.
  • the triggered ready position is shown in FIG.
  • the locking member 5 pivots back, for example by a leg spring, not shown, back into the locking position and locks the sole retainer 1 in the manner described above as soon as it is in the driving position according to Fig.l or 3 have returned.
