Abstract

A camera support collar or ring for releasable attachment to the upright post of a photographic camera assembly support which includes a clamping means with an adjustable collar made up of first and second semi-circular segments with a threaded screw means secured to one of the segments for releasably holding the segments in post-gripping disposition at a predetermined elevation on the camera receiving post. A radially extending housing extends outwardly of one of the semi-circular segments and releasably retains a camera position locking pin therein, with the locking pin being arranged for axial movement to an elevation above the upper surface of the collar for engagement with a camera assembly mounted upon the upright post above the upper surface of the adjustable collar, thereby permitting the user to reposition the camera assembly following movement from a prescribed or desired position.

Claims

1. In combination with an upright support for a photographic camera assembly, the support having a base means and a camera receiving post extending upwardly therefrom, clamping means for releasable attachment to the post at a predetermined elevation in camera supporting position immediately below a camera mounted on said post;

the improvement comprising;

(a) said clamping means including an adjustable collar having first and second semi-circular segments with threaded screw means secured to said first segment and engaging said second segment for releasably holding said first and second segments in post-gripping disposition and at a predetermined elevation on said post; and

(b) a radially extending housing extending radially outwardly from one of said semi-circular segments and releasably retaining a camera position locking pin therein, said camera position locking pin being arranged for axial movement to an elevation above the upper surface of said first and second collars within said radially extending housing for engagement with a camera assembly mounted upon said upright post axially adjacent said clamping means, the arrangement being such that said photographic camera assembly is supported by said adjustable collar.

2. The improvement as defined in claim 1 wherein said threaded screw means includes a knurled knob at the proximal end thereof.

3. The improvement as defined in claim 1 being particularly characterized in that frictional detent means are provided for releasably retaining said camera position locking pin in desired axial disposition.
