Definitions

  • the invention relates to a safety ski binding with a releasable jaw, in which at least one holding member engaging a ski shoe to be held is held in its holding position by a two-part holding part, on one part of which a spring determining the holding force, supported on a housing part, engages and the latter second part engages on or on the holding member (s), these two parts being releasable with one another via a coupling device or at least connected in a movement-locking manner in the direction of the force of the spring, which coupling device is controlled by an evaluation circuit processing signals from at least one force transducer , reversible electric motor is controlled in its direction of rotation.
  • the coupling device has overlapping sections of the two, coaxially arranged parts of the holding part, in the area of which coupling bodies, preferably balls, are held on the overlapping section having an inclined shoulder, and in the overlapping section openings, the size of which is large the coupling body corresponds at least, are arranged.
  • This overlapping section is surrounded by a sleeve which has at least one clearance on its inner wall for receiving the coupling body, which covers the openings of the overlapping section in the released position of the coupling device and can accommodate the coupling body.
  • the sleeve itself is axially displaceable by an electric motor which is acted upon by a circuit which detects the forces acting on the binding.
  • the aim of the invention is to avoid these disadvantages and to propose a binding of the type mentioned at the beginning, in which it is possible to find out with a small and only little energy-consuming electric motor and nevertheless a high degree of safety against tripping is ensured even in the event of icing.
  • the coupling device is pretensioned with a coupling spring against its disengaged position in which the positive connection between the two parts of the holding part is released.
  • coupling bodies preferably balls
  • this overlapping section is surrounded by a sleeve which has at least one clearance on its inner wall for receiving the coupling body, which can cover the openings of the overlapping section and receive the coupling body in the released position of the coupling device
  • the coupling spring engages the sleeve in the circumferential direction and furthermore on a pawl part which is pivotally held and cooperates with the sleeve engages, wherein the shaft of the electric motor can be brought into drive connection, optionally via a transmission member with the pawl part and the sleeve.
  • the transmission member and the pawl part are arranged on the shaft of the electric motor, the former being held non-rotatably and the latter being rotatable.
  • the pawl part is substantially L-shaped, one leg cooperating with a radially protruding shoulder of the same, or can be brought into abutment against it and the second leg at in Release direction rotating shaft of the electric motor with an eccentric approach to the same or the transmission member can be brought into engagement.
  • the device monitoring the position of the shaft of the electric motor can be provided by position sensors which are arranged at certain points around the shaft and are connected to a corresponding evaluation circuit, or by a stepping motor which is used to drive the shaft controlling the transmission element is, and a corresponding control circuit is formed with a counter counting the individual steps of the stepping motor, the outputs of which cause a corresponding reversal and stopping of the stepping motor.
  • position sensors can be dispensed with, which also eliminates the need for adjustment work.
  • the transmission member is essentially cam-like and, when the shaft of the electric motor rotates in the direction of engagement of the clutch arrangement, comes to rest on and protrude from an extension thereof projecting in the radial direction from the sleeve, which preferably also engages the clutch spring the sleeve rotates against the force of the clutch spring.
  • the binding has two holding members which can be pivoted about axles 1 fixed to the housing and which serve as sole holders 2 and are L-shaped. These have an essentially L-shaped cross section and their legs, which run essentially parallel to the surface of the ski, overlap the sole of a ski boot.
  • the shorter legs 3 of the sole holder 2 are overlapped by a pressure plate 4 which is arranged on the end face of a two-part pull rod 5 serving as a holding part.
  • This pull rod 5 passes through a wall 6 of the housing of the jaw which runs essentially perpendicular to the ski surface and the longitudinal extent of the ski and is held displaceably in the latter.
  • the two parts 7 and 8 of the two-part tie rod 5 can be connected to one another via a coupling 9.
  • the part 8 of the two-part pull rod 5 is provided with a collar 10 and is axially displaceably guided in a bore in a further wall 11 of the housing of the jaw, which is essentially perpendicular to the surface of the ski and perpendicular to its longitudinal extent.
  • a spring 12 is supported, which is further supported on a further wall 13 which extends essentially perpendicular to the surface of the ski and perpendicular to its longitudinal extension and is designed as a compression spring.
  • the coupling 9 consists essentially of a sleeve 14 which passes through the wall 13 with play. 2 to 4, which show a view of the coupling 9 in the direction of the sole holder 2 with the wall 13 and the spring 12 omitted, this sleeve 14 is provided with four axially extending grooves 15 machined into its inner wall.
  • the sleeve 14 is provided with a cam-like extension 16 on which a clutch spring 17 engages, the second end of which is suspended in a pawl part 18.
  • the clutch spring 17 engages with one end in a bore 19 of the shoulder 16.
  • the cam-like extension 16 has a support shoulder 20 which interacts with a corresponding recess 21 on the pawl part 18.
  • the part 7 of the two-part pull rod 5 engages in the sleeve 14 and has a section 22 which is designed as a head and has a bore 23 which is open on its free end face.
  • the head 22 is guided with little play in the sleeve 14 and held axially displaceable therein.
  • this bore 23 engages the second part 8 of the two-part tie rod 5, which is also provided with a section 24 designed as a head, which merges into the remaining area of part 8 via a conical lateral surface 25.
  • Coupling bodies 26, which are designed as balls, are in contact with this conical lateral surface 25 of part 8 and are guided in radial bores 27 of head 22.
  • the position of the bores 27 is determined by the pressure plate 4 connected to the part 7 in a rotationally fixed manner, which has an essentially rectangular shape and can slide along a base plate 28, whereby rotation of the pressure plate 4 and thus of the part 7 is prevented.
  • the grooves 15 cover the bores 27 of the head 22.
  • the coupling bodies 26 can therefore be pushed radially outwards by the conical outer surface 25 of the head 24 of the part 8 are, whereby the positive connection is released and a transmission of tensile forces via the coupling 9 is practically no longer possible.
  • all that is required to pivot the sole holder 2 is to overcome the force of a relatively weak return spring 29, which is supported on the shoulder of the head 22 and the wall 6 and is designed as a compression spring.
  • the control of the clutch 9 can be seen better from FIG. 5.
  • the pawl part 18 is loosely rotatable on a drive shaft 30 which passes through the wall 13.
  • the electric motor 31 driving the drive shaft 30 is arranged between the walls 13 and 11 of the housing and is provided with an attached gear.
  • a transmission member 31 is held in a rotationally fixed manner on this drive shaft 30.
  • This transmission member 31 has a driver 32 which cooperates with the pawl part 18, which is substantially L-shaped.
  • the driver 32 of the transmission member 31 bears against the shorter leg of the pawl part 18.
  • the drive shaft 30 is rotated by the clutch spring 17 in the direction of arrow R.
  • the control edge 35 of the transmission member 31 comes to rest against the cam 36 of the extension 16 and rotates it back together with the sleeve 14 until the position shown in FIG. 4 is reached and the support shoulder 20 of the extension 16 into the recess 21 of the pawl part 18 snaps into place.
  • the electric motor 37 rotates the drive shaft 30 and thus the transmission member 31 back into the position shown in FIG. 2, in which the driver 32 rests on the pawl part 18 or only a very small gap remains between the latter and the driver 32 to be able to trigger the jack part 18 after a short distance.
  • the electric motor 37 can be controlled via corresponding position sensors which, for example, detect the position of the transmission element 31 and thus that of the drive shaft 30 and reverse the direction of rotation of the electric motor 37 as soon as it receives a trigger signal which processes it in a known manner by signals from force transducers Evaluation circuit, which can be designed, for example, according to DE-OS 25 19 544, has traveled a sufficient distance in the triggering direction (arrow A) for triggering.
  • the trigger signal which is in itself only available for a very short period of time from such an evaluation circuit can be maintained, for example, by means of a monostable multivibrator circuit for a sufficiently long time, for example 20 seconds.
  • a further reversal of the direction of rotation takes place after reaching the position of the transmission member 31 or the drive shaft 30 shown in FIG. 4. After reaching the rest position shown in FIG. 2, in which the driver 32 is very close to the shorter leg of the pawl part 18 the electric motor is shut down.
  • the position of the drive shaft 30 or the transmission element 31 can also be monitored without a position sensor.
  • the electric motor 37 can be designed as a stepping motor, which is controlled via a control circuit that can be triggered by a trigger signal and that defines the above-mentioned sequence in the form of certain number of steps in both directions.
  • the triggering can take place very quickly due to the small required travel of the drive shaft 30, the relatively strong coupling spring 17 for rapid rotation of the sleeve 14 even in difficult conditions, such as e.g. with ice buildup.
  • the binding can be reset to the usable state after a release, since after a skier falls, a time span of approx. 20 to 30 seconds can be expected before he is able to get back into the binding. Since the opening of the clutch spring 17 can take place at a very low speed when the sleeve 14 is reset, since at least 30 seconds elapse between a fall with the binding being released and re-entry into it, the electric motor need only have a correspondingly low output, so that it is small can be built.

Abstract

Une fixation de sécurité pour skis à mâchoire libérable comprend au moins un organe de retenue qui s'applique sur la chaussure de ski à retenir et qui dans sa position de retenue est retenu par une pièce de retenue en deux parties. Un ressort qui s'appuie sur une pièce formant boîtier agit sur la première partie de la pièce de retenue et détermine la force de retenue. La deuxième partie de la pièce de retenue agit sur le ou les organes de retenue. Ces deux parties peuvent être reliées l'une à l'autre par un dispositif d'accouplement (9), de manière détachable, ou peuvent au moins se déplacer ensemble dans la direction où s'exerce la force du ressort (12). Le dispositif d'accouplement (9) est commandé par un moteur électrique (37) à sens de rotation reversible commandé par un circuit d'évaluation des signaux provenant d'au moins un transducteur de force. Afin de pouvoir remettre une telle fixation avec une force minime, une fois qu'elle a été libérée, le dispositif d'accouplement (9) est précontraint par un ressort d'accouplement (17) dans le sens opposé à sa position libérée, position dans laquelle la liaison entre les deux parties (7, 8) de la pièce de retenue (5) qui les fait se déplacer ensemble est défaite.
