Definitions

  • the present invention relates to a device for detecting incorrect posture on a ski, comprising a arranged on the ski binding for receiving a ski boot, wherein below the ski boot a plurality of communicating with an evaluation unit, vertical pressure receiving vertical sensors for detecting the center of gravity of the ski boot wearing Person are arranged.
  • Such a device is already out of the US Publication 2005/0050945 A1 previously known.
  • two sensor arrangements which should provide conclusions about the attitude of a person standing on these sensor arrangements.
  • These are pressure sensors, which are connected to an evaluation unit, which determine whether a strong or less strong pressure on the forefoot or under the heel of the skier loads.
  • the evaluation unit will record the measurement results of the pressure sensors and determine whether the skier holds himself more or less straight on the ski. From the determined values of the evaluation unit, a recommendation for the correction of the attitude of the skier is determined, which is forwarded to the skier via a display arranged on the ski tip.
  • the sensors are in this case subdivided into two groups of four sensors, of which in each case a cross-linked group of sensors are arranged below the front region of the foot and below the heel region of the foot.
  • a cross-linked group of sensors are arranged below the front region of the foot and below the heel region of the foot.
  • an array of four sensors each is used to cover a common area of the shoe. This is the case because any unevenness must be compensated below the shoe, so that an average value of each interconnected sensors is determined in a common area. In addition to the unevenness and possibly still existing within the binding mobility of the shoe, this requires a regular recalibration of the system, if not the accuracy is to be reduced to a level that no reasonable evaluation allows more.
  • the present invention is based on the object of specifying a simplified device for detecting incorrect postures on a ski, which can simultaneously improve the measurement accuracy and thus provide a more accurate assessment of malpositions on the ski while improving handling ,
  • the sensors are still arranged below the ski boot, but these are located between the binding and the ski itself.
  • the ski boot is on the binding plate, which in turn presses flat on the vertical sensors and thus already provides an averaged result for the sensors.
  • the accuracy of the sensors can be significantly improved.
  • a preliminary configuration for determining the shoes acting on the pressure sensors can thereby be dispensed with.
  • the center of gravity of the skier who is more or less vertically above the binding, is determined by evaluation with the aid of an evaluation unit.
  • the sensors are in data connection with the evaluation unit, for which purpose either a cable connection or a radio connection between the sensors and the evaluation unit is kept ready.
  • a suitable energy store or a generator, via which both the sensors and the evaluation unit are fed, is also provided.
  • the binding is mounted floating on the vertical sensors, that is connected exclusively via the vertical sensors with the ski. Actuation of the sensors by the pressure acting on the binding is ensured in this case. A bridging of individual sensors due to attachment of the binding directly to the ski is thereby avoided.
  • the vertical sensors according to the invention may be subdivided into front and rear vertical sensors in order to be able to determine the center of gravity between the front and the rear measuring point, similar to the prior art.
  • the front and rear vertical sensors may each include right and left vertical sensors, which also allow to detect a cornering of the ski in which the pressure on one side increases, while on the other side it is lowered.
  • the overall arrangement may also be associated with at least one horizontal sensor, which can each receive a horizontal pressure and / or a horizontal tension.
  • a horizontal sensor will be arranged in front of or behind the binding, so that the binding exerts pressure or tension on the horizontal sensor when driving downhill or uphill.
  • Both such a horizontal sensor can be arranged on one side of the binding, ie front or back, as well as in both positions.
  • sensors may be provided, in particular sensors for determining the driving speed or inclination sensors, which may support the evaluation by the evaluation unit. For example, it may be useful to determine, for a determination of the incorrect attitude during cornering, whether such cornering exists at all, or whether unevenness of the runway or the like is possibly no longer present. Furthermore, it is possible for the evaluation units of the two skis used at the same time to be in a data connection with one another, so that the values of the two skis are determined and taken into account in connection with each other.
  • piezoelectric pressure sensors can be used as sensors, which allow a very exact determination and provide directly usable input signals for the evaluation unit.
  • a display which in the field of vision of the driver corrective suggestions for the attitude of the driver displays.
  • a display can be arranged, for example, on the skis themselves, but an arrangement can also be arranged in the form of a head-mounted display, or an integrated display on the ski poles or other aids of the skier.
  • a transmission to a device such as the wrist is so far conceivable without further notice.
  • a display in this sense can be either a high-resolution TFT, LCD, LED or other appropriate display, or even a display consisting of individual LEDs, which only forward rudimentary information.
  • the evaluation unit passes on the instructions for correcting incorrect postures to a vibrator band which the skier has wrapped around his leg.
  • a vibrator belt are associated with a plurality of eccentric motors via its annular circumference, upon actuation of which a vibration occurs in the respective region of the belt.
  • the driver can be taught in which direction he should shift his weight.
  • Such a vibrator belt may in turn be cable-connected either to the ski and thus to the evaluation unit, but also to communicate with the evaluation unit by suitable radio technology, Bluetooth and the like.
  • the vibrator band can be an energy storage available for this purpose, which on the one hand allows communication and on the other hand operated the Exzentermotoren.
  • FIG. 1 shows a ski 1 on which a person stands using a ski boot 2.
  • the ski boot 2 is connected to the ski 1 via a binding, wherein the binding fixes the ski boot 2 in a front area by means of a centering holder 4 and in the rear area by means of a heel holder 5 on the ski 1.
  • the ski boot 2 is in this case flat on a binding plate 3, on which also the centering 4 and the heel 5 are arranged.
  • vertical sensors 7 are arranged, which can determine a vertical pressure, which causes the skier on the binding plate 3.
  • front and rear vertical sensors 7 are to be distinguished, from whose position the possibility arises to locate the position of the center of gravity of the skier on the ski 1.
  • a horizontal sensor 6 is arranged, which is connected to the binding plate 3.
  • the horizontal sensor 6 will be able to detect both a pressure and a drag of the binding plate 3 and thus be able to determine whether the ski 1 is just possibly passing a bump and therefore has a particular pressure on one of the vertical sensors 7, or if the Drive downhill at a certain time.
  • An evaluation unit not shown here is in communication with all sensors 6, 7 in the data exchange and evaluates the measurements of the sensors 6, 7 from. From this the evaluation unit generates a recommendation for the attitude of the skier, whereby in the case that an intervention in the momentary attitude is necessary seems to be a signal to the skier passed.
  • a signal is given in the present case via a control of an eccentric motor, which is arranged on a vibrator belt 8, which carries the skier around his thigh. Due to the position of the vibration which can be detected when driving on the vibrator belt 8, the skier knows that a corresponding correction of his posture is required. An influence is possible in this way, without having to direct the skier's view away from the slope to a display and thus to provoke accidents from carelessness.
  • FIG. 2 shows a ski 1 with removed binding plate 3, only with the horizontal and vertical sensors 6, 7. While a horizontal sensor 6 is sufficient, as far as this is loadable on pressure and train, in the present case a total of four vertical sensors are used, on which the binding plate 3 is attached. This allows a distinction of a pressurization not only front and rear, but also right and left, so that more information about cornering and the corresponding attitude when cornering can be determined.
  • the ski can be assigned further sensors, such as inclination sensors or speed sensors, which can enhance the evaluation of the vertical sensors 7 and of the horizontal sensor 6.
