Abstract

PURPOSE: To detect rise and fall without changing the line of sight and to constitute a variometer simply and inexpensively. CONSTITUTION: Light guiding bodies 36 and 37 are mounted to the upper and lower edges of a shield plate 21a of goggles 21 which a paraglider pilot wears and each edge part of the light guiding bodies 36 and 37 is inserted into a housing part 23 provided at a string 21b of the goggles 21, thus applying each emitted light of the light emitting elements 22a and 22b in the housing 23. When the flight-rising exceeds a specific value, the light emitting element 22a is turned on, light is emitted downward from the total length of the light guiding body 36. Then, when the flight-lowering exceeds a specific value, the light emission element 22b is turned on, light is emitted upward from the total length of the light guiding body 37, thus alarming is given to each pilot.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a variometer for detecting a change in atmospheric pressure when a paraglider or a hang glider is used to detect rising and falling of the flight and notify the operator.

[0002]

2. Description of the Related Art FIG. 4 shows a conventional variometer for detecting changes in atmospheric pressure. A meter type display 12 is provided on the upper front of the housing 11, a numerical type display 13 is provided in the center, setting switches 14 such as a power switch and a reset switch are provided below, and a buzzer sound is emitted. The indicators 12 and 13 in which the holes 15 are formed are composed of light emitting diodes (LEDs). The housing 11 is provided with a fixing band 16,
For example, it may be attached to a paraglider harness, or attached to the legs of an operator. A pressure sensor or the like is provided in the casing 11, a change in flight altitude is detected from a change in atmospheric pressure during flight, and a change in flight ascending or descending is displayed on the indicators 12 and 13 and a buzzer sounds. .

[0003]

In the conventional variometer for detecting atmospheric pressure change, the detection information is given to the operator by a buzzer sound and a meter such as an LCD. However, the information notification by the display has the following problems. It was 1) Paragliders fly in good weather,
Sunlight may enter the display, making it difficult to see.

2) In view of the visibility of the display in flight, there is no degree of freedom in the mounting position and it has to be attached to the foot, which may hinder the movement. 3) Since the display is viewed during flight, it takes time to look at the display with the field of view temporarily removed from the direction of travel or other places to which the eyes are directed. 4) Meter type display and numerical display are expensive in themselves.

Further, the notification of the buzzer sound has the following drawbacks. 1) Cannot be used together with wireless communication. 2) The sound of wind may interfere. 3) Since the housing 11 has to be mounted in a place where the buzzer sound is easily heard, the degree of freedom in mounting is small.

4) In order to make it easier to hear, a buzzer with a large sound pressure must be used, and the buzzer becomes large, the power consumption becomes large, and the power source becomes large. There was a limit to miniaturization.

[0007]

According to the present invention, the goggles to be mounted during flight are provided with light emitting elements, and the light emitting elements are controlled to be lit by detection outputs of flight ascent and descent. The means for detecting the ascent and descent of the flight are provided away from the goggles. Especially, the upper edge light guide and the lower edge light guide are attached along the upper edge and the lower edge of the inner surface of the shield plate of the goggles, respectively, and the light of the light emitting element turned on by the rising detection output is guided by the upper edge light guide. The light of the light emitting element which is incident on one end of the body and is turned on by the fall detection output is incident on one end of the lower edge light guide.

FIG. 1 shows an embodiment of the present invention. The operator of the paraglider wears the goggles 21 as eyeglasses to protect his eyes from wind pressure, and the light emitting element 22 is attached to the goggles 21. That is, in the goggles 21, the front surface facing both eyes is a shield plate 21a, and both ends thereof are connected to the ears 21b and 21c for hanging on the ears. Vine 2
A thin plate-shaped small accommodating portion 23 is formed near the shield plate 21a of 1b, and an LED (light emitting diode) is provided in the small accommodating portion 23.
A light emitting element 22 such as

On the other hand, the portion for detecting the ascent and descent of the flight is provided as the main body 24 apart from the goggles 21,
For example, as shown in FIG. 2, a harness 26 of, for example, a paraglider is sandwiched between a sandwiching piece 25 attached to the back surface of the main body 24 and the main body 24, and held by the harness 26. As shown in FIG. 3A, for example, an atmospheric pressure sensor 27 and an electric power source unit 28 are accommodated in the main body 24, and the atmospheric pressure detected by the atmospheric pressure sensor 27 is stored in the CPU.
Is input to the signal processing unit 29, and it is determined whether the flight has started to rise or fall from the state of change in the detected atmospheric pressure, and the drive unit 31 is controlled by the rise or fall of a predetermined value or more to control the inside of the goggles 21. Lighting control of the light emitting element 22 is performed. In other words, the goggle 21 is provided with the ascending light emitting element 22a and the descending light emitting element 22b, the ascending light emitting element 22a is lit when the ascent rises above the predetermined value, and the descending light emitting element 22b is caused when the ascent falls above the predetermined value. It is lit.

In this example, pin jacks 33 are attached to both ends of the cord 32, one of the pin jacks is connected to a connector provided in the accommodating portion 23 on the goggle 21 side, and the other pin jack 34 is connected to the connector of the main body 24. The driving unit 31 is coupled and connected to the light emitting elements 22a and 22b. A part of the body 24 serves as a lid 35 for replacing the battery in the body 24.

As shown in FIG. 1D, a sponge layer is formed on the inner peripheral edge of the shield plate 21a of the goggles 21 in order to improve the feeling of contact with the face and to maintain a space between the face and the shield plate 21a. 38 is formed, but in this example, an upper edge light guide 36 made of, for example, an acrylic resin is provided between the upper edge of the inner surface of the shield plate 21a and the sponge layer.
Between the lower edge of the inner surface of the shield plate 21a and the sponge layer 38, and the lower edge light guide 37 is attached along this.

One end of each of the upper edge light guide 36 and the lower edge light guide 37 is extended and inserted into the accommodating portion 23 of the goggle 21, and the light emission of the light emitting elements 22a and 22b is incident on the inner end portion of the insertion. Is being done. The light emitting elements 22a and 22b are mounted on a printed circuit board 41, and the printed circuit board 41 is mounted with a connector 42 that is coupled to the pin jack 33.

When the ascending / descending detecting means 43 including the atmospheric pressure sensor 27 and the signal processing section 29 detects the ascending flight of a predetermined value or more, the light emitting element 22a is turned on,
As shown in FIG. 3B, light is emitted from the entire length of the upper edge light guide 36 to the lower side, and the operator is informed that the light is rising above a predetermined value. When the detection means 43 detects a flight descent of a predetermined value or more, the light emitting element 22b is turned on, and light is emitted upward from the lower edge light guide 37 over its entire length, as shown in FIG. It is reported that it is descending more than the value.

It is also possible to change the blinking cycle of the light emitting elements 22a and 22b according to the ascending and descending speeds of the flight. The upper edge light guide 36 is omitted, a plurality of light emitting elements 22a are arranged and provided at the position of the upper edge light guide 36, and the lower edge light guide 37 is omitted, and the lower edge light guide 37 is omitted. A plurality of light emitting elements 22b may be provided at the position.
