(54) TRAINERS FOR FENCERS

one

The invention relates to sports simulators and is intended for fencing trainers.

Known simulator for fencers, containing weapons with a sensor of injections, target and indicator device with counters 1.

The disadvantage of the known simulator is that it does not allow measuring the temporal parameters of the movements of the fencer.

The purpose of the invention is to increase the accuracy of the assessment of movements of the fencer.

The goal is achieved by the fact that the swordsman's simulator containing a weapon with a thrust sensor, a target and an indicator device with counters has an acceleration sensor mounted on the weapon, and the indicator device contains three counters and a command bar, the first output of the acceleration sensor being connected to the input The start of the first counter and the input Stop of the second counter, the second output of the acceleration sensor are connected to the inputs of the Stop of the first and second counters, the inputs of the Start of the second and third counters are connected to the bus

The “command and input” Stop of the third counter is connected to the injection sensor.

The drawing shows a structural diagram of the simulator.

The simulator contains a motion analyzer 1 consisting of the first counter 2, counting the delay time, and the second counter 3 counting the latent time, the third counter 4 counting the total time, the input command bus 5 mounted on the weapon of the fencer of the acceleration sensor 6, the body of which made of electrically insulating material, such as plexiglass. The acceleration sensor has two outputs, representing two pairs of contacts 7 and 8. The first output 7 is located in the direction of correct movement relative to

15 drops of mercury 9, which is in potential me. In order to eliminate false positives, the channels for promoting mercury are machined at an angle to the horizontal line, somewhat larger than the angle of the weapon in the fencer's stance. Sensor attached to

20 to the arms 10. A debris 11 or an electrically conducting bib, worn on the trainer, is attached to the common (ground) point of the entire

,;: 1s: in the device's circuit, the same acceleration sensor is attached to the trainer's weapon.

Unlike sensor / .ka, on the weapon of the tested athlete, in the sensor of the trainer both contact pairs are paralleled. The latent 3 and total 4 time counters have a common starting bus 5. The start input of the delay time counter is connected to the first output, i.e., to the contact pair 7, which is closed when the movement is incorrect. Input “Stop delay counter is connected to the cat acts 8 (second exit). Since the counter of latent time must be triggered at any beginning of movement, this counter has two inputs: Stop, connect,:;: -h to both outputs 7 and 8 of the athlete's sensor. Weapon 10 of the athlete is connected to the entrance “Moan counter 4 total time. The start input of counter 4 is connected to a common command 5 command.

The device works as follows.

Before the beginning of the test, the coach gives the athlete an introductory image. The idea that when moving his (coach) arms, the athlete must make an injection into the breastplate of the coach. Drop the electrical circuit of the counters to zero. When a trainer's weapon moves, a mercury ball in the “Teams” sensor closes one of the contacts, and “Teams. Counters 3 and 4 are running. If the athlete makes a shot incorrectly, i.e., makes an initial movement in the direction of the back shot, then the counter 2 is started from the contact 7 and the counter 3 stops from the same contact. Then the weapon goes to the side of the breastplate and the contacts 8 are closed, stopping the counter 2 delays. The “Stop at counter 3” signal does not change anything, since it has already been stopped. Further, when the weapon 10 touches the bib or the target 1, the total time counter 4 stops. Thus, three inscriptions appear on the display of the device:

1. The time taken by the athlete to perform the wrong part of the movement.

2. Hidden - latent time.

3. The total time spent on the reception.

When properly performed, after the arrival of the signal, Command Counter 2,

not starting, it is immediately set to Stop. With the same signal from bus 8, counter 3 also stops. In this case, counter 2 flashes 000, ms, counter 3 — ABC, ms, that is, three

latent time digits and counter 4 flash three digits — total reception time, ms. The proposed device allows detecting the faults of fencing equipment in the form of express analysis directly during training. The proposed device is used as a device-informer and simulator that promotes the development of correction techniques and speed of fencing techniques.

The economic effect of the invention is to reduce the time spent on training athletes.
