Description

[Detailed description of the invention] "Object of the invention" - (Field of industrial application) The invention of ÷ is 1! Concerning a starting frame forming device using laser light at a boat race track (Prior art) In boat races held at boat racecourses using small motor boats, a flying start system is adopted. As shown in Figure 3, the 6th race boat SO launched from the pit 10 on the side of the stand 12, and once reached the 21! ! Of the turn signs set up at the start line, 18
(The racers gather near the No. 2 turn sign 16 just before zero, take off all at once in accordance with the start signal from the big clock, and race while turning these two signs 14 and 16 in a circular motion a predetermined number of times.

(The point that the invention is trying to solve) The conventional 7-flying start method is - simultaneous start, starting at 718 and 71 before it at 71 - μ fin 20 (
The race is valid if all 30 cars are in that area within 1 second from 0 (18% before), and at least one boat jumps out of this starting line 18 within this time) or Far A /・If you are behind Fin 20, the race will be discontinued. Neon lights are momentarily emitted from Neon Funde on Fin 20 and the starting line 18, and the status of each boat 50 during that time is shown. A slit photograph is taken to determine whether the race is successful or not.

However, if the V-Success is not successful, the amount that must be refunded to the V-Success ticket purchaser will be approximately 100%.

In addition, in this Fufuying O start method, the first
Boat racer 30, who made the first turn from the inner race, stayed in the lead for most of the race and just went!・I often go inside. Therefore, each member tried to take the inside course by killing the first sign 14, so-called ``taking the inside'', and then ``running away''.
do. Each crew member following the top boat said “i< rJ” from above.
, tried to reverse the situation using tactics such as "sashing", but was unable to reverse the situation.
Since there are many cases where you go/l-in in the same position, the outcome of the race is decided by the first person who takes the long sword, and the interest in V-s is halved.

Furthermore, after the net, the six race boats 30 rushed toward the first marker 14 to the sound of ``In Torishi'' and made a turn, but they slipped due to centrifugal force, and each boat came into contact near the 11th marker 14. However, in the worst case scenario, the boat capsizes and the first athlete falls into the water and is injured.

Therefore, it is conceivable to form a start frame on the extension line of the start line 18 by emitting visible light and draw a race boat t4 within these start frames, but since visible light is easily diffused, this method is not recommended. Many lenses must be used to converge p, so the device is large and therefore ineffective.

This invention was made in an attempt to eliminate such conventional problems with t-rays, and its main purpose is to
In the conventional 7-flying start system, laser beam oscillators are installed at regular intervals behind the running course in front of the stand 12, and the laser beams emitted from these laser beam oscillators are used to move the running course at regular intervals. parallel stars) 4
2i11, each race boat 30 is formed into a groove within these starting frames, and the stars are lined up in a row to form an impossible star. - Each time a race starts, a laser beam oscillator is driven to form a starting frame, which determines the fairness and safety of boat race starts.

Furthermore, this invention makes it easier to start a boat race.
Rather than a system, the purpose is to raise the interest of boat racing from the start by lining up in a line across the starting line and launching them, similar to horse racing, bicycle racing, auto racing, etc.

“Invention W4” '5I of this invention! An example will be described with reference to the drawings.

Starting line 18 of the running course in front of stand 12
A laser beam oscillator 22 is provided on the rear quay 15.

The laser beam oscillator n launches the race boat 50 of 611,
Seven oscillators are installed in a line horizontally at regular intervals on the quay 15, one for each oscillator, and control units 22 for these oscillators are installed at required locations in the competition headquarters (not shown).

Also, the laser beams emitted from all the oscillators 22 are parallel to each other starting P? so that it forms.

"Function" (as mentioned above), each laser beam generator 221 - on the quay 13 on the extension line of the starting line 18 in front of the stand 12 -
The control unit 22 is connected to the control unit 22 in the competition headquarters.

At the start of each race, the control unit 24 is operated to emit seven parallel laser beams 22 from the seven laser beam oscillators 22 toward the start line 18 in front of the start 12 as shown in FIG.
t to form starting frames at regular intervals.

"Effect" According to the present invention, six starting frames are formed by the laser beam 26 on the water surface in front of the stand 12, so the six racing boats 30 enter their respective courses and reach the starting line 1.
You can line up in a line horizontally to 8 and start fairly and safely.

If the emission of the laser beam 26 is immediately stopped after each driver passes the starting line 1B, the running of each driver will not be hindered.

Furthermore, there are no facilities on the running course, so the boat race is 60.
There will be no hindrance to the navigation of the other 1 government vessel.
