Abstract:
A protective device for photographic apparatus comprises an umbrella with a shaft which slides in a ball joint having a compressible o-ring that fits inside a groove within the ball joint. The ball joint is held in place with compression screws joining two halves of a collar system which are adjusted to provide the desired frictional setting to maintain the umbrella in the desired position. A slide bar with an attachment bolt at one end and a stop at the other is used to attach the present invention to the base of a camera or video device and provides the slide wherein the collar system is moved to a desired position. The collar system includes grooves whereby the shaft of the umbrella may be rotated to lie flat against the collar system to facilitate storage and tilting of the photographic apparatus. The umbrella collapses pulling the protective canopy down along shaft for easy storage.
