Abstract

PURPOSE:To put a titled measuring instrument to practical use, and to utilize it widely in other field, too, by providing a time counting device, a caluculating device, an optical display panel, etc. on one measuring instrument. CONSTITUTION:As for a time counting device, when a power source 1 is turned on, a second flickering 2' is started, a time-set button 2 becomes on automatically, a time is displayed on a display panel 5 by a numerical key 6, and thereafter, said device is started. As for a calculating means, a calculating key of a mode 3 is depressed. Addition, subtraction, multiplication and division, an angle, % and a square root can be calculated by calculation operating keys 6, 7 and 8. When the key is depressed again after the calculation has been ended, the means is returned to a time display. When a measured value on a map as an actual value, a reduced scale display key of a mode 9 is depressed. Said value is displayed optically by graduations and a numeral on a panel 11 and 11'. As for a reduced scale which is different depending on a map, said operation is executed by selecting the key of the mode 9.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an orienteering A1 equipment equipped with various devices and notification means.

In an orienteering competition, participants accurately trace points or courses shown on a map and compete for the best time. Therefore, measuring the position and distance of the course at opening is an important task for the competitors. For example, competitors start by memorizing or writing down the start time on a watch they carry, but sometimes they need to calculate the elapsed time. In orienteering competitions, points are set between the start and the finish line, and calculating the time taken to pass the point and the time between points is troublesome.

A device equipped with a conventional orienteering compass Kid timing device.

Orienteering is a sport that makes full use of maps and magnets, but competitors must interpret the values measured on the map as actual measurements.

For example, in a map with a scale of 1:25,000, the length of 11 pieces on the scale is actually Ki-t 25 m. Competitors must make these conversions each time they are measured. In order to find a point, the contestant finds a reference point on the map, calculates the direction and distance on the point map using the number of steps, and looks at the point. However, the L7, the conventional orienteering compass Vcn, and the popular VC are equipped with a conversion scale [
7, and high-end products are replaced with attachments for each scale side. These attachments are often lost during competitions, or become unusable due to damage or bending.

Recently, orienteering competitions have begun to include point) K questions. For example, a problem is set that requires calculations such as the difference in elevation between points and how many meters is the horizontal distance between points. Question f requires more complex calculations, making it a difficult task for the contestants in a time-competitive competition, and points will be deducted even if the answer is wrong. However, conventional orienteering compasses have
Computing equipment is equipped and powerful.

As described above, there is no known product among conventional orienteering instruments that is equipped with a notification means that can convert the scale scale using a timing device, a calculation device, or an optical display.

The present invention has been made in view of these drawbacks; its purpose is to put a timekeeping device, a calculation device, an optical display panel, etc. into one instrument and put it into practical use.

Hereinafter, the present invention will be described in detail by way of examples and with reference to the accompanying drawings.

FIG. 2 is a plan view of a specific orienteering instrument made according to the present invention.

When you turn on the power with the clock device 1, 2' stops blinking and the time set button d of 2 automatically turns on and 6
After displaying the time on the display panel LC9 of 5 using the numeric keys,
Start button 2. Timing starts from this point. This time measurement continues until the power supply 1 is turned off.

1. When you press the mode 3 calculation key, the time display on the display panel 5 disappears and the calculation key 6.7.8 is pressed.
With the VC, you can calculate addition, subtraction, multiplication, division, angle, %, and 1/''. After completing the calculation, press the key again to return to the time display.

In addition, to display the measured values on the map as actual values vcB, press the scale display key in mode 9, and panel
is displayed optically with a scale and numbers. Different scales depending on the flI diagram are performed by selecting the mode 9 key. 1o
and 10' are always displayed in centimeter scale. 12 is a magnetic needle, 13 is an angled rotary disk, 14 and 1
4' is the magnetic north line.

Example 1 The contestant sets the starting statute of limitations 1 in advance, that is,
When you turn on the power at step 1, the clock mechanism goes into standby.
2' starts flashing seconds. After displaying the time on the panel 5 using the number key 6, press the time set button VC2 at the same time as the start button 7.

At this time, the blinking of seconds at 2' corresponds to 0, and from this point on, timekeeping begins and continues until the power supply 1 is turned off. Therefore, competitors do not need to memorize or take notes on the start time using this device.

To actually locate points on the map in the field,
After selecting a reliable location that is common to both the map and the field, find out the actual measurements from the selected location to the point on the map. That is, when the same scale display key as the map is pressed in mode 9 of the present invention, the scale and numbers are converted to actual values and displayed on corners A, 11 and 11'. The contestant can easily find out the actual distance (α meters) by applying the scale section 11 or 11' to the selected point on the map.

Next, when you press the mode 6 calculation key, the time display on the display panel 5 becomes ready for calculation, and the actual value (α meters) is displayed on the display panel 5 using the numeric keys, and you can calculate your average walking time. Divide by the width (h centimeters) to find the number of steps. Next, by using the magnetic needle 12 and the rotary disc with variable angle, you can find the point by taking the number of steps in the direction you need to go.

There are questions for each point, and there are 6 calculation keys for questions such as horizontal distance between points, altitude difference, angle, etc.
．． 7.8 allows addition, subtraction, multiplication, division, angle calculation, etc.

It goes without saying that the orienteering instrument of the present invention can be widely used not only in orienteering but also in the fields of mountain climbing, skiing, trekking, and driving.
