Torlaufstange for skiing

Technical area

The invention relates to a door running rod for skiing, in particular a door running rod for ski slalom racing

State of the art

The ski slalom is an alpine competition discipline in which the racer on the descent a variety of

Direction changes with different, sometimes very tight radii is required. The directional changes are dictated by a composition of individual gates and gate combinations adapted to the terrain. 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.

In order to increase the tension in a competition, intermediate times or intermediate speeds are measured at certain points of the slalom route and commented on during the presentation of the competition event. Usually, in the meantime measurement electronic photoelectric sensors used, which are interrupted by the slalom driver when passing through the measuring point. In this way, the commentary of the competition gains in tension, because not only the end time but in real time during the race, a comparison between the current

Runners and, for example, a leading runner can be commented on.

In ski slalom or gate running, the distance between two consecutive goals is often very narrow. It is difficult with photocells to capture a representative number of split times. Due to the high speed of the racer, there is also a high event density of the measured values to be processed. With previously known measuring methods, it is hardly possible to exactly grasp the time at which a racer actually passes a gate running bar.

Presentation of the invention

It is an object of the present invention to provide a Torlaufstange for ski racing, through which in a ski race, the detection of split times in a simple manner and with high accuracy is possible.

This object is achieved by a door running rod with the features of claim 1. Advantageous embodiments of the invention are the subject of dependent claims.

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.

Preference is given to 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.

Favorable for 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.

Advantageously, it is provided in a preferred embodiment that 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. In a further embodiment it is provided that 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

Time of impact reflected on the tilt rod. The time module may be a conventional electronic clock module that provides a time base appropriate to the application.

With regard to the miniaturization, it is favorable if 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.

Advantageously, 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.

Another preferred embodiment of the door running bar is characterized in that 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.

When equipping the entire racetrack of a door run with the door running rods according to the invention, 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.

In the preparation of these measurement data, comparisons between a pre-racer or a topper can be displayed anywhere in the slide show presentation of the slalom race by a numerical representation or by a graphic, .B a time bar, anywhere.

Brief description of the drawing

To further explain the invention, reference is made in the following part of the description to the drawings in which further advantageous embodiments, details and further developments of the invention can be found. Show it: FIG. 1 shows a time recording system according to the invention;

Figure 2 is a sectional view of the door running rod according to the invention with an electrical device;

FIG. 3 is a block diagram of the electrical device;

Figure 4 shows a first embodiment of the invention with an event message in which a

Identification information of the door running bar according to the invention is included;

Figure 5 shows a second embodiment of the invention with an event message, in which in addition to the

Identification information also includes a time entry.

Embodiment of the invention

The sketches in 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. When 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. When reversing, 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 according to the invention 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 race course on goal bar base can thus be represented by the "intelligent goal pole" according to the invention. A comparison with the respective leader, the development of a projection or an enlargement of the residue can be directly displayed in a live transmission of the competition event. In Figure 3, 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 transmitting device 9 may be a conventional radio module. The impact exerted by the racer 20 on the gate 2 is detected by a detector device 10. The detector device 10 may be designed as an acceleration sensor or as a tilt angle sensor. Such sensors, which can detect an acceleration or inclination in three dimensions, are commercially available in a miniaturized design. The electrical device 7 may be integrated by embedding in the polymeric material of the tilting rod 2.

As drawn in the block diagram, 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. By means of the triggering 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." On the other hand, the time module 15 is set to a start value by the triggering signal.

4, the event message 12 of a first embodiment of the invention is shown schematically. The event message 12 has a first message field 13, in which an identification information 23 is included. On the basis of the identification information 23, each gate runner 2 of the evaluation unit 17 clearly be identified. In the present example, this is the door running bar number 37, which reports the event of the abutment or the inclination angle change. 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. Within a time recording system 1, which is constructed with gate rods 2 of this embodiment of the invention, the transmission time is delayed by one, technically conditioned, time interval. Because of this

Time interval for all gate runners 2 is equal, 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. Here, the event message 12 is composed of a first 13 and a second message field 14. In the second message field 14, a time information 24, which indicates the time of the impact again. The detection of this time takes place in the door running rod 2. Here, at the moment of the abutment, the time predetermined by the time module 15 is taken over into the second message field 14. The time module 15 is a commercially available electronic clock module. In the example shown in FIG. 5, this time is given as follows: three minutes, sixteen seconds and thirty-first hundredths of a second. Also in this

Embodiment of the invention, the event message 12 is transmitted via the free space transfer channel 16 to the evaluation unit 17. Unlike the first Embodiment (Figure 4), 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 time of sending must be timely only in terms of the presentation of the information, but is irrelevant for the recording of the meantime.

The invention is of course not limited to the illustrated embodiments. For example, 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. Furthermore, it appears possible that the door running rod 2 according to the invention are also used in other sporting competitions, such as, for example, snowboarding or whitewater sports.
