Abstract

An information display means as a part of or for attachment to a diver'"'"''"'"'s face mask, and including diver status indicators such as a clock, compass, air pressure gauge or the like, located out of the diver'"'"''"'"'s usual line of sight, and further including reflecting surfaces, one of which is offset from such usual line of sight but encompassed by the diver'"'"''"'"'s field of vision so that an optical path is provided from such reflecting portion to the status indicators, enabling the diver to selectively view his surroundings or the reflected image of the status indicators.

Claims

1. The combination of a diver'"'"''"'"'s underwater face mask including a frame portion, and a transparent viewing plate mounted to said frame portion and extending in a plane substantially normal to the diver'"'"''"'"'s usual line of sight;

and information display means comprising;

an attachment frame for detachable mounting to said face mask as a forward extension thereof, including mounting means secured to said frame portion of said face mask;

diver status indicators mounted to the upper portion of a peripheral flange of said attachment frame out of said usual line of sight; and

at least a pair of reflecting surfaces carried by the lower portion of said flange, a reflective portion of one of said reflecting surfaces being encompassed by the diver'"'"''"'"'s angle of vision but offset from said usual line of sight, said reflecting surfaces providing an optical path sequentially from said reflecting surfaces and thence to said status indicators whereby the diver can selectively view his surroundings or the reflected image of said status indicators.

2. The combination of claim 1 wherein said status indicators include a clock to display the elapsed dive time.

3. The combination of claim 1 wherein said status indicators include a compass in which the compass card is altered to provide a correct reflected image.

4. The combination of claim 1 wherein said attachment frame in use is open to the water whereby a portion of said optical path is through water.
