Definitions

  • the invention relates to a safety ski binding with a releasable jaw, in which at least one holding member engaging on a ski boot to be held is held in the holding position by a two-part holding part, on one part of which a spring which determines the holding force and is supported on a housing part engages and its second part engages on or on the holding member (s), these two parts being detachable or detachable with one another via a coupling device. At least in the direction of the force of the spring, it is possible to connect them in a movement-locking manner, which coupling device is controlled by an electric motor which is controlled by an evaluation circuit which processes signals from at least one force transducer and which is reversible in its direction of rotation.
  • the coupling device has overlapping sections of the two parts of the holding part arranged coaxially to one another, in the area of which coupling bodies, preferably balls, are held on the overlapped section having an inclined shoulder and openings in the overlapping section , the size of which corresponds at least to the size of the coupling body.
  • This overlapping section is surrounded by a sleeve which has at least one clearance on its inner wall for receiving the coupling body, which, in the released position of the coupling device, has the openings in the overlapping section ⁇ covers 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 sufficiency with a small electric motor which requires little energy, and nevertheless a high degree of safety against tripping even in the event of a failure solution is guaranteed.
  • this is achieved in that the coupling device is pretensioned with a coupling spring against its disengaged position, in which the movement-locking connection of 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 cover the openings of the overlapping section in the released position of the coupling device and receiving the coupling body
  • the coupling spring engages the sleeve in the circumferential direction and further a swiveling one that cooperates with the sleeve attacks the older pawl part, the shaft of the electric motor being able to be brought into the drive connection, possibly via a transmission element with the pawl part and the sleeve.
  • the transmission element 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 essentially L-shaped, the one leg cooperating with an extension of the sleeve protruding radially from the sleeve, or being able to be brought into contact with the latter, and the second leg can be brought into engagement with an eccentric extension of the same or the transmission member when the shaft of the electric motor rotates in the triggering direction.
  • the device which monitors the position of the shaft of the electric motor can be controlled 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 transfer member controlling shaft see vorge, and a corresponding drive circuit counting with the individual steps of the stepping motor Zäh ⁇ be formed ler whose outputs tion a 'corresponding Umsteue ⁇ and stopping effect of the stepping motor.
  • the arrangement of position sensors can be dispensed with, which also makes adjustment work unnecessary.
  • the transmission member is essentially cam-shaped and, when the shaft of the electric motor rotates in the direction of engagement of the clutch arrangement, on an extension thereof protruding in the radial direction, on which the clutch spring preferably also engages. comes to rest and rotates the sleeve 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, with their thighs running 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.
  • the coupling 9 consists essentially of a sleeve 14, which passes through the wall 13 with play.
  • This sleeve 14 is, as shown in FIGS. 2 to 4 which is a view of the clutch 9 show in the direction of the sole holder 2 with omission of the wall 13 and the spring 12, with fourlichar in their inner wall ⁇ beitete axially extending grooves 15 provided.
  • the sleeve 14 is provided with a cam-like projection "- provided 16 to which a clutch spring engages 17, whose second end is suspended in a pawl member 18
  • the Kupplungsfe engages ⁇ 17 with its one end into a bore 19 of the lug sixteenth
  • the cam-like projection 16 has a support school ⁇ ter 20, which cooperates with a corresponding recess 21 on the pawl member 18th
  • the part 7 of the two-part tension rod-5 engages in the sleeve 14 and has a head formed as Ab ⁇ section 22 having an open at its free end face bore 23rd
  • the head 22 is guided with slight play in the sleeve 14 and hold it axially displaceable ge ⁇ .
  • the second part engages 8 of the two-part tow rod 5 a, which is also provided with a formed as a head portion 24, the leaf via a KEGE ⁇ lateral surface 25 in the remaining area of the part exceeds 8 goes.
  • Coupling bodies 26, which are designed as balls, bear against 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, which is non-rotatably connected to the part 7 and 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 prevents it is.
  • the grooves 15 cover the bores 27 of the head 22.
  • the coupling bodies 26 can therefore radially follow through the conical outer surface 25 of the head 24 of the part 8 be pushed outside, 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 On this drive shaft 30, a transmission member 31 is held in a rotationally fixed manner.
  • This transmission link 31 has a driver 32, which cooperates with the pawl part 18, which is substantially L-shaped.
  • the driver of the transfer member 31 In the in Fig. 5 and 2 rest position of the clutch, corresponding to the normal state of the binding, and is provided in a Ü ⁇ Bertra supply of tensile forces shown, is the driver of the transfer member 31 on the shorter leg of the pawls ⁇ part 18 at the 32nd
  • the ratchet member slides with its longer leg in a lateral exemption 34 of the lug 16, in the region of this at ⁇ set a smaller thickness (Fig. 3) .
  • the electric motor 37 can be controlled via corresponding position sensors, which, for example. the position of the transmission member 31 and thus that of the drive shaft 30 and the direction of rotation of the electric motor 37 as soon as it receives a trigger signal which, in a known manner, is processed by an evaluation circuit which processes signals from force transducers and which, for. B. can be designed according to DE-OS 25 19 544, has traveled a sufficient distance for triggering in the triggering direction (arrow A).
  • the trigger signal which is provided by such an evaluation circuit only for a very short period of time, can be used e.g. B. by means of a monostable multivibrator circuit for a sufficiently long time, e.g. 20sec.
  • a further reversal of the direction of rotation takes place after reaching the in the Fig. 4 illustrated position of the transmission member 31 or. the drive shaft 30.
  • the electric motor is stopped.
  • 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 by a control circuit which can be triggered by a trigger signal and which defines the above-mentioned sequence in the form of certain number of steps in both directions.
  • the release can take place very rapidly due to the 30 ge rings required therefor path of the drive shaft, the relatively strong spring clutch 17 for rapid rotation of the sleeve 14 even when 'difficult conditions, such. B. with ice buildup.
  • the binding can be put back into the usable state after a release, since after a skier falls, a time span of about 20 to 30 seconds can be expected until the skier is able to get back into the binding.

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.
