Abstract

A diving goggle has a transparent lens made of glass or plastics. The lens has a depth displaying part made of a liquid crystal display for displaying a dived depth, and an oxygen remainder displaying part made of a liquid crystal display for displaying an amount of oxygen remaining in an oxygen cylinder carried by a diver. The displaying parts are connected to a display controller, which is connected to a depth detector and an oxygen remainder detector.

Description

1. Field of the Invention

The present invention relates to a diving goggle, and particularly to a diving goggle that enables a diver to check necessary diving information at any time.

2. Description of the Prior Art

A diver puts a diving goggle on his face and instruments for measuring a dived depth and an amount of remaining oxygen somewhere on his body, for example on his arm, and reads measurements of the instruments during diving to protect himself from submarine sickness and an oxygen shortage.
When the instruments are put on the diver's arm, the diver sometimes forgets to check the instruments particularly when he is being absorbed in the diving. This may risk the diver to the submarine sickness and oxygen shortage.
A preferred embodiment of the present invention provides a diving goggle that enables a diver to confirm necessary diving information without fail.
The present invention provides a diving goggle having a lens comprising a displaying part for displaying diving information necessary for a diver, detecting means for continuously detecting the diving information during diving, and display controlling means for displaying the diving information detected by the detecting means on the displaying part of the lens. The diving information includes a dived depth and/or an amount of oxygen remaining in an oxygen cylinder.
The depth and/or the amount of oxygen remaining in the oxygen cylinder detected by the detecting means is displayed by the display controlling means on the displaying part of the lens of the diving goggle. A diver, therefore, can always check important information such as the depth and the oxygen remainder.
The diving goggle may be detachably or fixedly connected to a face mask including a regulator mouthpiece, which will particularly be utilized in skin diving. The term "diving goggle" used herein and also in claims should be understood to include such a face mask type goggle.
Further objects and advantages of the invention will be understood from the following description when read in conjunction with the accompanying drawings in which:-
Figure 1 is a schematic view showing a diving goggle according to an embodiment of the invention.
In Figure 1, a diving goggle 1 comprises a transparent lens 2 made of glass or plastics, a lens holder 3 made of rubber or synthetic resin and holding the lens 2, and a band 4 made of rubber or synthetic resin fitted to the holder 3 to hold the diving goggle 1 on a diver's face.
The lens 2 has a depth displaying part 5 composed of a liquid crystal display (LCD) for displaying a dived depth, and an oxygen remainder displaying part 6 composed of an LCD to display an amount of oxygen remaining in an oxygen cylinder (not shown) carried by a diver.
The displaying parts 5 and 6 are connected to and controlled by a display controller 10. The display controller 10 is connected to a depth detector 11 for detecting the dived depth, and an oxygen remainder detector 12 for detecting the amount of oxygen remaining in the oxygen cylinder. The depth detector 11 is located to submerge during diving, and the oxygen remainder detector 12 is fitted to the oxygen cylinder.
With this arrangement, a dived depth is detected by the depth detector 11, and displayed on the depth displaying part 5 under the control of the display controller 10. An amount of oxygen remaining in the oxygen cylinder is detected by the oxygen remainder detector 12, and displayed on the oxygen remainder displaying part 6 under the control of the display controller 10.
As explained above, pieces of diving information such as the depth and oxygen remainder required by the diver are always displayed on the displaying parts 5 and 6 located at a corner of the lens 2 of the diving goggle 1 to easily catch diver's eyes. The diver can, therefore, anytime confirm the depth and oxygen remainder during diving without fail, so that the diver may always be cautious to protect himself from the submarine sickness, oxygen shortage, etc.
The present invention is not limited by the embodiment explained above but is achievable in various forms without departing from the spirit thereof. For example, the displaying parts 5 and 6 may be formed of light emitting diodes (LEDs), fluorescent character display tubes, etc., instead of the LCDs.
In summary, the present invention can continuously display information pieces that must always be checked by a diver during diving such as a dived depth and an amount of oxygen remaining in an oxygen cylinder carried by the diver, on a displaying part of a lens of a diving goggle, so that the diver can anytime check the information pieces without fail to protect himself from diving accidents caused by forgetting to confirm such information pieces.

Claims

A diving goggle having a lens, comprising:

a displaying part formed on the lens to display diving information that must be confirmed during diving;

detecting means for continuously detecting the diving information during the diving; and

display controlling means for displaying the diving information detected by said detecting means on said displaying part.
The diving goggle as claimed in claim 1, wherein the diving information includes at least one of a dived depth and an amount of oxygen remaining in an oxygen cylinder.
The diving goggle as claimed in claim 1, wherein the displaying part comprises a liquid crystal display.
