Abstract: A configurable light fixture for photography is presented. The light fixture includes a rail with a clamp section and threaded section. A fixed jaw is removably coupled to an end of the rail in the clamp section. One or more optional sliding intermediate jaws may be slidably coupled to the rail in the clamp section below the fixed jaw to create more clamping surfaces when desired to hold more than one lighting tube. A sliding end jaw is slidably coupled to the rail in the clamp section below the sliding intermediate jaw. A wing nut is coupled to the threaded section of the rail for applying linear pressure on the sliding end jaw thereby secure a lighting tube on each of the clamping surfaces.

Abstract: An equipment support stand for mounting and positioning photographic, motion picture and video accessories and the like. A riser comprising a plurality of telescoping shafts is coupled to lower, center and upper support legs which, when activated, will position the riser vertically relative to the mounting surface. Each support leg is integral with a respective positioning sleeve, the center and upper positioning sleeves being rotatably coupled about the lower end of the riser. Each positioning sleeve includes at least one engagement surface which is adapted to interface with the adjacent positioning sleeve or sleeves. When engaged, each of the three support legs are angularly spaced from adjacent support legs by 120° of arc. The center positioning sleeve may be secured to the riser in the engaged position. In the closed state, the center and upper support legs may be rotated about the riser and be placed in a co-planar relationship with the lower support leg to facilitate storage and transport.

Abstract: An equipment support stand for mounting and positioning photographic, motion picture and video accessories and the like. A riser comprising a plurality of telescoping shafts is coupled to at least three rotatable support legs which, when activated, will position the riser vertically relative to the mounting surface. Each support leg is integral with a positioning sleeve which is rotatably coupled about the lower end of the riser. Each positioning sleeve includes at least one engagement surface which is adapted to interface with the adjacent positioning sleeve or sleeves. When engaged, each of the three support legs are angularly spaced from adjacent support legs by 120.degree. of arc. In a closed state, the support legs may be rotated about the riser and be placed in a co-planar relationship with one another to facilitate storage and transport.

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.

Abstract: A coupling for mounting and positioning photographic, motion picture and video accessories and the like. A mounting sleeve is adapted to be secured to an equipment supporting member. A fixed positioning disc depends from and is integral with the mounting sleeve. A cylindrical shaft is axially coupled to and extends from the fixed positioning disc. A first rotatable positioning disc is disposed about the cylindrical shaft, a frictional stabilizing member being disposed between the fixed positioning disc and the first rotatable positioning disc. A second rotatable positioning disc is annularly disposed about the cylindrical shaft in proximity to the first rotatable positioning disc. The adjacent surfaces of the first and second rotatable positioning discs have disposed therein reciprocally aligned pairs of linear channels of varying width and depth, each pair of linear channels being adapted to receive and secure equipment supporting shafts of differing cross section.
