Abstract
A coupling for mounting and positioning photographic, motion picture and video accessories and the like. A receiving base couples the positioning head to an equipment stand shaft, the receiving base being rotatable about the axis of the stand shaft. A first terminus of the receiving base incorporates an axially oriented beveled surface which is disposed within a cylindrical bore disposed through the head housing. The receiving base is maintained within the cylindrical bore in the housing through the engagement of and the force imposed thereon by an impinging stud bearing upon the beveled surface. A support post is mounted within the cylindrical bore of the housing extending outwardly in opposition to the receiving base. The end of the support shaft extending from the housing is fully rotatable about its interface with the housing. The engagement of the impinging stud against the beveled surface of the receiving base places the adjacent ends of the receiving base and support shaft in frictional engagement permitting the support shaft to be secured in a desired position.
