Abstract

A lens guard for protecting a camera includes a lens-guard housing, a pressurized gas system, and a gas supply. The housing defines an opening and has a transparent protective lens disposed in the opening and having an outer surface exposed to the environment, an upper portion, and a portion defining apertures shaped to respectively receive therein camera support rods operable to mount the lens-guard housing to the camera in front of a lens. The pressurized gas system is operable to remove fluids and debris from the outer surface of the protective lens. The pressurized gas system includes a blow tube mounted to the upper portion of the housing and having a plurality of outlets directed towards the outer surface of the protective lens. The gas supply fluidically connects to the blow tube and is operable to supply pressurized gas to the blow tube and through the outlets thereof.

Claims

1. A lens guard for protecting a camera, comprising:

a lens-guard housing defining an opening and having;

a transparent protective lens disposed in the opening and having an outer surface exposed to the environment;

an upper portion; and

a portion defining first and second apertures shaped to respectively receive therein first and second camera support rods operable to mount the lens-guard housing to the camera in front of a lens; and

a pressurized gas system operable to remove fluids and debris from the outer surface of the protective lens, the pressurized gas system including;

a blow tube mounted to the upper portion of the housing and having a plurality of outlets directed towards the outer surface of the protective lens; and

a gas supply fluidically connected to the blow tube and operable to supply pressurized gas to the blow tube and through the outlets thereof.

2. The lens guard according to claim 1, wherein the housing further comprises:

a lower portion; and

grooves in the lower portion shaped to direct fluid and debris away from the outer surface of the protective lens when the pressurized gas is exiting through the outlets.

3. The lens guard according to claim 1, further comprising a visor attached to the upper portion of the housing and shaped to protect at least a portion of the protective lens from weather and glare.

4. The lens guard according to claim 1, further comprising:

the first and second camera support rods; and

first and second bushings operable to be respectively received within the first and second apertures and, thereby, adjust an inner diameter of each of the first and second apertures to conform to a size of the first and second camera support rods.

5. The lens guard according to claim 1, wherein the housing has a receiving groove formed within the opening about a perimeter thereof to receive therein the protective lens.

6. The lens guard according to claim 1, wherein the housing has a detent formed about an outer circumference thereof and which further comprises a protective camera cover operable to:

water-tightly fit about the detent to attach the protective camera cover to the lens guard; and

receive the camera therein and protect both the camera and the lens of the camera.

7. The lens guard according to claim 6, wherein:

the protective camera cover is comprised of a transparent, water-proof material; and

the material is tactile to allow for operation of the camera through the material of the protective camera cover.

8. The lens guard according to claim 1, wherein the pressurized gas system has a remote control and is remotely operated.

9. The lens guard according to claim 1, wherein the gas supply has a gas source and fluidically connects the gas source to the blow tube.

10. The lens guard according to claim 9, wherein the gas source is a portable compressed gas cylinder.

11. A camera protection device, comprising:

a lens guard mountable to a lens-side of a camera for protecting a camera lens thereof, the lens guard having;

a housing defining an opening and having;

a transparent protective lens disposed in the opening and having an outer surface exposed to the environment;

an upper portion; and

a portion defining first and second apertures shaped to respectively receive therein first and second camera support rods operable to mount the lens guard to the camera in front of a lens; and

a pressurized gas system operable to remove fluids and debris from the outer surface of the protective lens, the pressurized gas system including;

a blow tube mounted to the upper portion of the housing and having a plurality of outlets directed towards the outer surface of the protective lens; and

a gas supply fluidically connected to the blow tube and operable to supply pressurized gas to the blow tube and through the outlets thereof; and

a protective camera cover secured to and extending from the lens guard and shaped to enclose the camera therein.

12. The camera protection device according to claim 11, wherein the housing further comprises:

a lower portion; and

grooves formed in the lower portion shaped to direct fluid and debris away from the outer surface of the protective lens when the pressurized gas is exiting through the outlets.

13. The camera protection device according to claim 11, further comprising a visor attached to the upper portion of the housing and shaped to protect at least a portion of the protective lens from weather and glare.

14. The camera protection device according to claim 11, further comprising:

the first and second camera support rods; and

first and second bushings operable to be respectively received within the first and second apertures and, thereby, adjust an inner diameter of each of the first and second apertures to conform to a size of the first and second camera support rods.

15. The camera protection device according to claim 11, wherein the housing has a receiving groove formed within the opening about a perimeter thereof to receive therein the protective lens.

16. The camera protection device according to claim 11, wherein:

the protective camera cover is comprised of a transparent, water-proof material; and

the material is tactile to allow for operation of the camera through the material of the protective camera cover.

17. The camera protection device according to claim 11, wherein:

the housing has a detent formed about an outer circumference thereof; and

the protective camera cover has a gasket operable to form a water-tight fit about the detent to attach the protective camera cover to the lens guard.

18. The camera protection device according to claim 11, wherein the protective camera cover has a closure mechanism operable to substantially close the protective camera cover around the camera.

19. The camera protection device according to claim 11, wherein the pressurized gas system has a remote control and is remotely operated.

20. The camera protection device according to claim 11, wherein the gas supply has a gas source and fluidically connects the gas source to the blow tube.
