Abstract
A diving mask with supplemental lateral and posterior fields of vision. A pair of compartments which extend outwardly from opposite sides of the diving mask have fixed mirrorized surfaces which reflect light rays from objects at the sides and rear of the mask into a diver's view. In a first aspect of the invention, the fixed mirrorized surfaces are parallel to a front portion of the mask. In a second aspect of the invention, the fixed mirrorized surfaces extend outwardly and rearwardly from the opposite sides of the mask. In a third aspect of the invention, the fixed mirrorized surfaces extend outwardly and forwardly from the side portions of the mask. The compartments are preferably separately sealed to preserve the reflectance of the mirrorized surfaces, prevent fogging and avoid the necessity of cleaning.
Claims16
A diver's mask having supplemental fields of vision, comprising:
- a frame, said frame having a front portion for receiving a lens;
- a transparent lens for admitting light rays from objects in front of a diver;
- a pair of adjoining compartments extending outwardly from opposite side portions of said frame;
- each of said compartments having a transparent rear wall;
- a front wall, said front wall having a fixed mirrorized surface for reflecting light rays entering said compartment through said transparent rear wall from objects at the rear and sides of said mask into said diver's view;
- a seal joined to a perimeter of said mask for preventing water from entering said mask;
- and a strap having end portions attached to end portions of said frame for mounting said mask on said diver.
A diver's mask having supplemental fields of vision, comprising:
- a frame, said frame having at least one end compartment extending outwardly from a side portion of said frame, said compartment having a transparent rear wall portion for admitting light rays into said compartment from objects at the rear and side of a diver and an adjoining front wall, said front wall having a mirrorized surface for reflecting said light rays entering said compartment through said transparent rear wall from said objects at the rear and side of said diver into said diver's view;
- a seal joined to a perimeter of said mask for preventing water from entering said mask;
- and a strap having end portions attached to end portions of said frame for mounting said mask on said diver.
A diver's mask having supplemental lateral and posterior fields of vision, comprising:
- a frame, said frame having a front portion for receiving a lens;
- a transparent lens for admitting light rays from objects in front of a diver;
- at least one compartment extending outwardly and rearwardly from a side portion of said frame, said compartment having a transparent rear outer wall for admitting light rays into said compartment from objects at the rear and side of said diver, a front outer wall having a mirrorized Mylar film adhesively applied to an inner surface of said front outer wall for reflecting said light rays entering said transparent rear outer wall into said diver's view, and a transparent inner wall adjoining said compartment's rear and said front outer walls for preventing fogging and a necessity of cleaning said mirrorized film by sealing said compartment from an interior portion of said mask which is adjacent to said lens;
- a seal joined to a perimeter of said mask for preventing water from entering said mask;
- and a means for attaching said mask to said diver.
A diver's mask having supplemental lateral and posterior fields of vision, comprising:
- a frame, said frame having a front portion for receiving a lens;
- at least one compartment extending outwardly and rearwardly from a side portion of said frame, said compartment having a transparent outer rear wall for allowing light rays to enter said compartment, a front wall having a mirrorized inner surface for reflecting said light rays entering said compartment's transparent rear wall into a diver's view, and a transparent inner wall for sealing said compartment;
- a seal joined to a perimeter of said mask for sealing said mask against a face of said diver;
- and a means for attaching said mask to said diver.
In a diver's mask having a front portion for receiving a lens, side portions and a seal extending around a perimeter of said mask for preventing water from entering said mask, the improvement comprising at least one water-tight compartment attached to one of said side portions of said mask, said compartment having a mirrorized surface for reflecting light rays entering a transparent rear portion of said compartment into said diver's view for viewing objects outside said diver's normal field of vision.
A method for augmenting a diver's field of vision comprising the steps of:
- admitting light rays from objects at a side or rear of said diver into a sealed water-tight compartment at a side portion of a diver's mask, said compartment having a front portion which is substantially parallel to said diver's eyes, said light rays passing through a transparent wall of said compartment;
- and reflecting said light rays off of a mirrorized surface of said compartment into said diver's eyes.
