Definitions

  • the invention relates to a door running rod for skiing, in particular a door running rod for ski slalom racing
  • the ski slalom is an alpine competition discipline in which the racer on the descent a variety of
  • Each individual gate or gate combination consists of one or two tilt rods anchored in the snow or ice, which the athlete, whose body is protected by protectors, touches and turns over when he passes the gate.
  • the measurement of the race time is usually electric and begins when the competitor crosses the starting line with the lower leg; it ends when the
  • Competitor passes the finish line with any part of the body or equipment.
  • Runners and, for example, a leading runner can be commented on.
  • the invention is based in a basic idea of detecting the instantaneous event of the passage of a gate through the gate shaft itself and this information to transmit an electrical device to an evaluation unit.
  • the door bar according to the invention is characterized in that an electrical device is provided, which controlled by an event that triggers a racer when he passes the gate and pushes against it, sends a directed to an evaluation event message in the space.
  • a door running rod which is designed as a tilting rod, which consists of an upper part, an elastic tilting part and a bottom part anchored in the ground, wherein the electrical device is arranged in the upper part.
  • the electrical device preferably has a detector device and a transmitting device with an antenna.
  • the radio transmission is an arrangement in which the antenna is arranged at an upper end remote from the bottom part of the upper part of the door running rod. This is particularly advantageous in a message transmission in radio technically unfavorable terrain.
  • the electrical device has a self-sufficient energy supply in the form of an electric battery, which is preferably accommodated in the lower region of the tilting rod. This ensures that the impact force that acts on the body of the racer when knocking over, not unduly high.
  • a time module is provided in the electrical device. Through this time module, it is possible to include in the event message, a time information that the actual
  • the time module may be a conventional electronic clock module that provides a time base appropriate to the application.
  • the transmitting device, the detector device and the time module are formed by an integrated electrical circuit. This chip can be easily integrated into the tilt rod.
  • the integrated circuit and the antenna are embedded in polymeric material.
  • the embedding can be done during the polymer consolidation during the manufacturing process of the gate.
  • Preferred as a polymeric material is polycarbonate, which does not splinter when the door running bar and the risk of injury of the athlete is reduced.
  • a preferred embodiment of the door running bar is characterized in that the event message has a first message field that contains identification information which is assigned to the door running bar and that the event message is transmitted synchronously with the time of the impact. This ensures that in the evaluation the interim time from the date of communication and a, in the Evaluation unit tracking, precise time base, can be determined very accurately.
  • the event message has a first message field which contains identification information, which is associated with the touched door running bar, and has a second message field in which a time entry present in the time module at the time of the impact is entered , This ensures that the
  • Evaluation unit from the received event messages can easily determine the time between two gates by subtraction.
  • a time recording system is created in connection with an evaluation unit, which enables real time detection of intermediate times at each gate or gate combination.

  • FIG. 1 show a slalom competitor 20 in a chronological sequence of rastered individual images when passing individual goals or goal combinations of a racetrack 19.
  • the goals usually consist of two color-coded door runners 2, which are designed as so-called tilt rods and according to the competition rules are driven around. As can be seen from the sketch, these tilt rods 2 are handled by the competitor 20 when he passes the gate.
  • FIG. 2 shows a tilting bar 2 in a sectional view. It consists of a top 3, a elastic tilting joint 4 and an anchored in ice or snow 6 bottom part 5.
  • a racer 20 drives around a tilting rod 2
  • there is almost always a repelling of the tilting bar 2 either by the skier of the competitor 20 or by his body.
  • the upper part 3 of the tilting rod 2 tilts and, after passing through the gate, returns to its vertical starting position.
  • the door running rod 2 is now provided with an electrical device 7, which detects the reversal or a shock applied to the door running rod 2, and transmits a message to an evaluation unit 17 as a function of this event via radio.
  • the evaluation unit 17 receives via an antenna 18 this wirelessly transmitted message.
  • the evaluation unit 17 forms within the time recording system 1 a central unit in which the incoming event messages 12 of the individual goal posts 2 are evaluated and processed for presentation. This can be done, for example, such that the instantaneous intermediate time 21 or speed of a racer 20 is compared with a best time 22 and the comparison is displayed in a suitable form on a display device 25 (see FIG. 1) or included in the annotation of the racing event.
  • the electrical device 7 is shown in a block diagram. It consists essentially of an integrated circuit 26, which is supplied by a battery 11 with electrical energy.
  • the integrated circuit 26 has a transmitting unit 9, which is connected to an antenna 8.

  • the electrical device 7 may be integrated by embedding in the polymeric material of the tilting rod 2.
  • the electrical unit 7 also has a receiving device 27.
  • This receiving device 27 serves to receive a signal sent by the evaluation unit 17 trigger signal.
  • the electrical unit 7 is brought from an operating state with a reduced power consumption, a so-called “sleep mode", into a "normal operating mode.”
  • the time module 15 is set to a start value by the triggering signal.

  • the event message 12 shown in FIG. 4 is transmitted by the transmitting device 9 immediately after the detected initiation in this first exemplary embodiment.
  • the transmission time is delayed by one, technically conditioned, time interval. Because of this
  • the evaluation unit 17 can calculate the actual time back. In conjunction with a running in the evaluation unit 17 time base thereby the intermediate times of a racer 20 over the entire racetrack 19 can be determined exactly.
  • FIG. 5 shows a second exemplary embodiment of the invention.

  • the event message 12 is transmitted via the free space transfer channel 16 to the evaluation unit 17.
  • the time of transmission to the evaluation unit 17 is irrelevant, since the event message 12 in addition to the identification of the door running rod 2 (number 037) also carries the time of the impact event with it.
  • a comparison with a central time base in the evaluation unit 17 is no longer necessary for the detection of the meantime here.

  • the invention is of course not limited to the illustrated embodiments.
  • the electrical device 7 could take into account not only the acceleration and the angle of inclination but also other parameters, such as a proximity sensor.
  • the door running rod 2 according to the invention are also used in other sporting competitions, such as, for example, snowboarding or whitewater sports.
