Definitions

  • the invention relates to a cross-country ski binding with a holding device for the given, all-elastically resilient holding of a sole or shoe attachment of a ski shoe to be held in the binding, a ball plate on which the sole of the ski shoe comes to rest when it occurs and a heel plate .
  • the elastically resilient holder does not enable safety tripping but only serves to make walking easier, it is often, e.g. To monitor performance training or the like, it is desirable to have an indication of the steps taken or an indication of the repulsive force applied in the individual steps.
  • the aim of the invention is to propose a binding of the type mentioned at the outset, which makes it possible to display the steps taken and / or the repulsive force applied.
  • a transducer which responds to physical quantities and emits electrical signals is provided, which is connected to an evaluation circuit which controls a display device, the transducer being located in or under the bale or Fe plate or is arranged in the elastically resilient holding device.
  • the transducers When the transducers are arranged in the resilient holder, it is possible to accommodate all of the assemblies of the device according to the invention in a confined space, it being possible to dispense with exposed connecting lines.
  • the physical variables to which the transducer responds can be forces, but also distances of parts of the transducer moving in one step of the rotor or angular relationships.
  • such displacement transducers can also be used to determine forces.
  • the force acting on it can be determined on the basis of a detected distance and knowledge of the spring constant of a part monitored by a displacement transducer.
  • the proposed measures make it possible, depending on the design of the switch-off, to display the steps taken or to display the repulsive force applied. In any case, it is possible to determine the corresponding values from the signals of the transducer corresponding to the applied forces.
  • FR-PS 2 510 ⁇ 9 ⁇ already proposed to arrange an electronic display device for displaying the pretension of the detent spring for a downward binding.
  • this can only be used to infer the holding force of the binding that is present in the respective circumstances.
  • e.g. recognize changes in the triggering forces or the setting values due to snow coverings.
  • the Auswe tesclien is designed as an integor, which is preceded by a threshold switch and which integrated signals of the transducer exceeding a certain value.
  • the number of steps covered can be determined, since each step is associated with the application of a corresponding, albeit small, repulsive force or a bending of the foot, as a result of which a change in the distance of a part of the shoe from the ski, or a change in the angle between the sole of the shoe and the ski occurs.
  • the evaluation circuit is formed by a peak value memory which detects the pressure peaks occurring in each step and which can be reset to a value close to zero each time the signals of the transducer fall .
  • This type of evaluation of the signals coming from the transducers makes it possible to monitor the repulsive force exerted at each step, which also enables the athlete's training performance to be appropriately monitored. It is also possible to transmit these values wirelessly to a display .. '. * i
  • the transducer is formed in two parts, one of these parts in or on the ball or heel plate and the other part on the base body, or one part on the pawl and the other part on the spring or is arranged on the mounting bracket, and that one part is formed from a permanent magnet and the other part from a Hall probe or another sensor that responds to a magnetic field.
  • the repulsive force applied at each step can also be determined, at least approximately.
  • EADERSHIP form can be provided that, the display device is connected to a selector switch which allows switching of the An ⁇ pointing mode.

  • 3 shows a vertical longitudinal section through an embodiment of a binding in the open state
  • FIG. 4 shows the embodiment according to FIG. 3 in the closed state
  • FIG. 5 is the top view corresponding to FIG. 2, and FIG. 6 shows the top view Fig. 4, the pawl is partially omitted.
  • FIG. 1 shows a block diagram of a device for displaying the steps taken or the pressure peaks occurring during the repulsion in the individual steps, as is provided for a binding according to the invention.
  • This device has a transducer 30 which measures the forces occurring or the distances or angular positions between the individual components of a binding having an elastically resilient holding device. corre sponding electrical signals.
  • This transducer 30 is connected to an evaluation circuit 31 ', which in turn can optionally be activated via an on-off switch 32, this on-off switch establishing the connection to a power source (not shown).
  • the evaluation circuit 31 is connected to a display device 33, which can be switched in its operating mode via a selector switch 34.
  • the evaluation circuit 31 can expediently essentially be formed by an integrator, which is preceded by a threshold switch. In this way, the integrator integrates all of the output signals of the transducer 30 that correspond to the threshold value being exceeded. This enables e.g. a display of the steps taken.
  • the evaluation circuit 31 can have a peak value memory which detects the pressure peaks occurring in each step due to the repulsion of ski and which can be reset to a value close to zero each time the corresponding signals of the transducer 30 drop. With such an evaluation circuit, the pressure peaks of the individual steps can be grasp.
  • these values can be displayed directly by means of the selector switch 34 or, if this is desired, for example, for monitoring the training of an athlete, by means of a transmitter (not shown) on a remotely arranged display device transferred, which may process these values even further. These values can be averaged over a certain time, for example. The latter can of course also be carried out in the evaluation circuit 31.
  • FIGS. 2 to 6 makes it possible to attach a shoe 22 which is only provided with a relatively short sole extension 6, in which through openings 23 are provided for receiving locking pins 2 of the binding (FIG. 2 and 5).
  • Di 's bond to the attachment of such a shoe comprises a bracket 1 having a ball plate 7, engages over the edge of the sole extension 6 of the shoe 22 and fixes soamit in the vertical direction.
  • a pivoting part 3 carrying a locking pin 2 cooperates with the holding bracket 1 in a manner that is evident from FIGS. 3 and 4.
  • Both the retaining bracket 1 and the swivel part 3 are mounted on a transverse axis 4, a spring S formed as a leg pivoting the retaining bracket 1 upward into the position shown in FIG. 3, as far as one to be described resilient holding device 10, 11 does not prevent this.

  • the pawl 10 and the spring 11 together also form the resilient holding device 10, 11.

The shoe is then pivoted downward together with the holding bracket 1 into the position according to FIG. 4 and held by the locking pins 2 which penetrate the through openings 23 in the sole extension 6.

  • This transducer 30 arranged in this way is expediently covered by a protective plate 30 'glued onto it.
  • a variant of the arrangement of the transducer 30 on the resilient holding device 10, 11 consists in arranging it in the area of the support of the spring 11.

Abstract

Fixation pour ski de fond comportant un mécanisme de retenue permettant de retenir, le cas échéant de manière élastique, un épaulement de semelle ou de chaussure sur une chaussure de ski à bloquer dans la fixation, et une plaque de talon. Dans le but de permettre à une telle fixation d'indiquer le nombre d'enjambées effectuées ou la force d'élan appliquée, un transducteur (30) monté d'une manière connue en soi, réagissant aux forces exercées et délivrant des signaux électriques, est relié à un circuit d'évaluation (31) qui commande le système d'affichage (33). Ledit transducteur est disposé dans le mécanisme de retenue (10) ou bien dans ou sous la plaque (7) d'éminence du gros orteil ou la plaque de talon, de manière à être protégé contre l'endommagement.
