JPS63135891A - Self measurement of time for ski racing - Google Patents

Abstract

PURPOSE:To facilitate time measurement, by transmitting a radio wave manually or automatically to stop measurement after it is started by pressing a start button of a stop watch. CONSTITUTION:At the start, a start button of a stop watch A carried by a skier is pressed to start measurement. At the goal, the skier presses a stop button mounted on a head of a stock grip B to stop the measurement with the stop watch A by transmitting a measurement stopping radio wave 8. Otherwise, a radio wave is radiated onto a goal line 7' from a transmitter C and the moment the skier reaches the goal, the reflection of the radio wave is sensed to stop the measurement by emitting the radio wave 8 for stopping the measurement of the stop watch A. This eliminates the need for setting up large-scale equipment thereby enabling a time measurement with a small and light device.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Purpose of the invention [Field of industrial application]
This invention relates to a method for self-measuring ski race time S1 in which four measuring operations at the start and finish can be performed at hand or with a simple device.

[Prior art] In the time measurement of ski competitions, this type of conventional technology uses a time meter 1IIl installed near the starting line 1.
The starting gate 2 linked to ¥&ii'73 is pushed open to start, and at the goal, a pair of optical sensors connected to the starting gate 2 with a cable 5, etc. are installed on the extension of the goal line 7. The time was sensed by the competitor blocking the space between the timepieces 4, and the measured time was displayed on a large time display board 6 connected by a cable 5 or the like. For full-scale competitions, official tournaments, etc., such obscure equipment is necessary, and
It is completely possible from an operational point of view. However, ordinary skiers
It is not suitable for the purpose of easily enjoying a time race with 131 Germans or a small number of people, or for athletes to easily train.

[Problems to be Solved by the Invention] The present invention does not require the installation of large-scale equipment, unlike the conventional measurement methods described above, and is small! It is lightweight, can be done anytime, anywhere, and with a small number of people without any hindrance to skiing, and is easy to run from the starting point to the finishing point.

(2) Structure of the Invention [Means for Solving the Problems] The present invention attempts to solve the following problems in order to enable the conventional time measurement method to be carried out easily even by a small number of people.

■ Eliminate the need for large-scale construction of cables between the start point, goal timing device, large time display board, etc., and eliminate radio waves that may cause interference between the start point and goal point. In order to eliminate this back and forth, we developed a method in which competitors carry a digital stopwatch with them, which has a timing start signal, a so-called memory function, a time display function, and a timing stop signal reception function.

■ The measurement stop function is implemented by pressing the transmission button on the radio wave transmitter VA placed on the stock grip head held by the athlete, which transmits radio waves to the digital stopwatch and stops measurement.

Furthermore, in case a player does not have time to press the start button, it is possible to install a radio wave transmitting device attached to a ball inserted near the goal.

■ At the start, in the conventional method, a warning signal followed by a start signal is issued mechanically, regardless of the athlete's will, but with the method of the present invention, the athlete himself or herself presses the start button. Since there will be 1 set, we decided to emit the signal sound for several seconds before the start signal in 3 stages in order to enable training on timing and timing of the start, where mental factors greatly affect the time. .

[Example] Embodiments of the present invention will be described with reference to the drawings.

FIG. 2 shows an embodiment of the principle of the invention.

In the figure, 1' is the start line, 7' is the goal line, A is a digital stopwatch, B is a stock grip-mounted push-button manual R-in device, and C is a box-built-in rechargeable automatic transmission device.

First, at the time of the start, the competitor presses the start button 9 on the digital stopwatch shown in Figure 3, which also serves as a digital watch, and the buzzer/alarm sound emitting section 10 of the stopwatch A emits a buzzer. A sound warning beep 1f- sounds for about 3 seconds, followed by a beeping alarm sound for about 5 seconds, and then a start sound is sounded and the measurement is started.

At the finish line, the famous competitors hit the stock grip head 11 with S! ! i! By pressing the stop button 12 of the transmitter B of the stock grip attached push-button handrail 1 shown in FIG.
The second-by-second measurement to the digital stopwatch received by the device stops.

In addition, the built-in charging box shown in Fig. 5 is removably attached to the installation ball 15 inserted into the snow surface directly beside the goal line 7', with the manual screw type mounting bracket 16 at the upper and lower mounting positions. The system automatically senses the diagonal of the radio waves emitted from the radiated radio wave transmitting slit directed above the goal line 7' from the automatic optical transmission device C at the moment the athlete crosses the finish line. After sensing by the part 18, a total of 31q stop radio wave transmitting part 19 transmits a measurement stop radio wave 8 to the digital stopwatch 8 carried by the contestant, and transmits it to the product 1 measurement stop radio wave 14.
The measurement to the digital stopwatch received by
Stubble.

Here, the radiation radio wave transmitting slit 17 and the radio wave sensing section 18 may be omitted, and the measurement stop radio wave 8 may continue to be emitted from the measurement stop radio wave transmitting section 19 when the dial A1 type switch 20 is ON.

In this way, as a 5tiff that stops the =1 measurement to the digital stopwatch, the stock grip attached push button Shikiko IJJ 5f! Although it is possible to use the communication device B and the rechargeable automatic transmitter C with a built-in box, if more accurate 81 measurement is required, such as during training for a competition, the rechargeable automatic transmitter with a built-in box can be used. Use device C.

In addition, if the color of the game is strong, or if you do not want to change the goal point frequently and installing the rechargeable automatic transmitter C with a built-in box is cumbersome, you can use the push button manual transmitter equipped with a stock grip. Device B alone is sufficient. Note that the start button 9 is a two-stage switch, and pressing it twice releases the switch, and pressing it again puts it in the start state.

In the figure, 21 is a digital time display board, 22 is at least 3
A memory button that enables the time memory and display of the time, 23 is a stop button, and 24 is the crown of the watch.

(3) Effects of the invention As described above, the present invention can improve the ski competition time self 3j.
In terms of measuring methods, it is much simpler and easier for individuals to measure time in ski competitions than conventional methods, which was difficult for individuals or small groups to do due to the complexity of so-called 51 stages of equipment. There is no problem with the skiing itself, and the start warning buzzer, alarm, etc. allow you to recreate the situation at the start of a real race, making it suitable for focusing your mind and developing your intuition for timing.

In addition, each device is easily portable, and the rechargeable automatic transmitter with a built-in box can be installed as needed, even if the area near the goal is a steep slope on rough terrain, just by inserting the ball into the snow surface. Place the device body on the ball, upper and lower mounting position: J
Simply attach it to a height that can be set at one section using a simple screw-type fixture.

Furthermore, the time measurement method according to the present invention is no different from the 4-way method which requires a large number of equipment in terms of the basic function of measuring time, so it can be carried out by multiple people.
Lime 1-Lyall lace is also measurable and has extremely large practical effects.
