Description

DETAILED DESCRIPTION OF THE INVENTION A8 OBJECTS OF THE INVENTION 1) Industrial Application Field The present invention relates to underwater goggles, and particularly to underwater goggles capable of displaying various information.

2) Prior Art Conventional underwater goggles generally consist of an eyeglass frame and a window formed by a transparent plate that is watertightly connected to the eyeglass frame.

The underwater glasses are used for swimming, scuba diving, and the like. The conventional underwater goggles are used for the purpose of keeping the eyes open underwater and observing underwater scenes.

3) Problems to be solved by the invention However, it is not only convenient for middle-aged people to be able to swim while knowing their time and pulse during swimming practice, but also because they know that the body is given an excessive amount of exercise. It can lead to heart failure. Also, if you can swim underwater while knowing the amount of oxygen remaining in the oxygen tank or the depth of the water while scuba diving, you may become so absorbed in swimming that you may be slow to notice that the remaining amount in the tank is low, or you may develop diving disease. It is possible to prevent accidents caused by erroneously diving to a depth that may occur.

In view of the above-mentioned circumstances, it is an object of the present invention to provide underwater goggles that can display various information. .

B1 Structure of the Invention 1) Means for Solving the Problems In order to solve the above problems, the underwater glasses of the present invention include a glasses frame and a window formed by a translucent plate watertightly connected to the glasses frame. It is visible because it is configured.

2) Function The underwater glasses of the present invention having the above-mentioned features include a display housing case fixed to the main body of the underwater glasses.

This display storage case houses an optical image display means having a display surface for optically displaying information, and an optical member for projecting information display light emitted from the display surface toward the inner surface of the transparent plate. Therefore, when various information is displayed on the display surface, the information display light emitted from the display surface is projected onto the inner surface of the light-transmitting plate by the optical member. The information display light is reflected on the inner surface of the light-transmitting plate, and is displayed on the optical image display means, which is a transmissive liquid crystal panel D1 as a display surface for optically displaying information, and then The light source D2 for backlighting is arranged at both sides. Further, the optical member A includes a concave lens A1,
It is composed of a prism A2 and a convex lens A3. The optical member A is configured to allow information display light emitted from the liquid crystal panel D1 to enter the inner surface of the transparent plate 2a. In addition, the liquid crystal panel DI
And the light source D2 is connected to the display circuit 4.

Next, the display circuit 4 will be explained with reference to FIG.

The display circuit 4 includes a switch 5 connected to the light source D2 and a power source 6 for the light source D2. The display circuit 4 also includes a power source 8 connected to the liquid crystal display D1 via a switch 7.

Further, the display circuit 4 has a clock circuit 9 operated by a crystal oscillator, and a clock signal outputted from the clock circuit 9 is transmitted to a clock circuit 10 and a counter circuit 11.
has been entered. The clock circuit 10 is reset by a reset signal from a reset button (not shown),
Measure the elapsed time (time) since the reset. The output terminal of this clock circuit 10 is connected to a selected terminal 12a of a changeover switch 12 for display data selection.

Further, the display circuit 4 includes a pulse sensor 13. This pulse sensor 13 has a near-infrared LED 13a and a near-infrared photodiode 13b arranged to face each other inside the tip of a clothespin-shaped clip, and is commercially available. When the ear tab P is inserted at the tip of the clip, the near-infrared light L
The near-infrared rays emitted from the ED 13a are transmitted through the ear tab P and detected by the near-infrared ray circuit 17. The detection signal of this bridge circuit 17 is amplified by an amplifier 18 and input to an A/D converter 19. This A/D converter 19
outputs a digital value of water pressure. The output terminal of the A/D converter is connected to the selected terminal 12c of the display data selection switch 12.

Selection terminal 1 of the changeover switch 12 for selecting display data
20 is connected to the liquid crystal panel D1 via a decoder 20 and a liquid crystal drive amplifier 21.

Next, the operation of the above embodiment will be explained.

The wearer of the underwater goggles 1 can view the underwater scene outside through the window 2 formed by the transparent plates 2a and 2b.

On the other hand, when the switches 5 and 7 are turned on, the selected terminals 12a, ], 2b, 1 of the changeover switch 12
However, the amount of light received by the diode 13b decreases each time more blood flows, so the number of fluctuations in the amount of light received is the same as the pulse rate. The detection signal of the pulse sensor 13 is amplified by an amplifier 14 and shaped into a rectangular wave by a waveform shaping circuit 15.

The rectangular pulses output from the waveform shaping circuit 15 are counted by a counter circuit 11 and converted into a pulse rate. The output terminal of this counter circuit 11 is connected to the selected terminal 12b of the changeover switch 12 for display data selection.

Further, the display circuit 4 includes a water pressure sensor 16. This water pressure sensor 16 has a casing [6&] and a diaphragm 16b, and a strain gauge 16c is attached to the back surface of the diaphragm 16b. When the water pressure outside the diaphragm 16b increases, the resistance value of the strain gauge i6c changes in accordance with the water pressure. Data for display of this change in resistance value is inputted to the decoder 20 from one of the bridges 2c, and is converted into image data for display by the decoder. Then, the display image data output from the decoder 20 is amplified into a liquid crystal drive signal by a liquid crystal drive amplifier 21 and input to the liquid crystal panel Di. The information light displayed on the liquid crystal panel D1 is projected onto the inner surface of the transparent plate 2a by the optical member A. The information display light reflected from the inner surface of the light projection plate 2a is visually recognized by a person wearing underwater goggles. Therefore, a person wearing underwater goggles can visually recognize the information display light superimposed on the underwater scene outside the transparent plates 2a and 2b.

When the selected terminal 121 & of the display data selection changeover switch 12 is selected, the display data output from the clock circuit 10 is displayed on the liquid crystal panel DI. In this case, the time (elapsed time) from when the clock circuit 10 was reset is displayed. Therefore, if a competitive swimmer uses it during practice, he or she can swim while knowing his or her own time.

When the selected terminal 121b of the display data selection switch 12 is selected, the display data output from the counter circuit 11 is displayed on the liquid crystal panel D1. In this case, the pulse rate is displayed. Therefore, if used by competitive swimmers or people who need to refrain from excessive sports, they can swim while knowing their own pulse rate.

When the selected terminal 121C of the display data selection switch 12 is selected, the A/converter 1
The display data outputted by No. 9 will be displayed on the liquid crystal panel D1. In this case, the water depth where you are swimming will be displayed. Therefore, if Diaper uses
You can swim underwater while knowing the depth of your current location.

It is also possible to display images of various scenes inside the pool and of fish swimming in the scenes so that the user can enjoy an underwater walk in the pool. Instead of switching and displaying various pieces of information, it is also possible to display only one type of information. The display storage case 3 may be attached to the glasses frame 1 not at the top of the glasses frame 1 but at the side thereof. and again,
Instead of being fixed only to the glasses frame 1, the display housing case 3 can also be fixed to the glasses frame 1 and the transparent plates 2b and 2a.

C. Effects of the Invention In the underwater glasses of the present invention described above, a display housing case is attached to the glasses frame, and an optical image display means having a display surface for optically displaying information and the display surface are installed in the display housing case. Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and is not limited to the scope of the claims. Various changes may be made without departing from the invention as described.
