Abstract
Abstract Apparatus for use in the assembly of a lighting fixture. A retaining spring clip bracket serves as releasable locking support and positioning constraint for elongated arcuate lamp shade panels peripherally encased in a plastic molding, and usually of transparent or translucent material. Brackets may be removed so as to remove the panels for transport, cleaning or for other purposes. Panles are suspended from a panel supporting structure. The structural spring means of the spring clip bracket releasably grasps the plastic molding covered edges so as to hold parts together by the frictional forces resulting from the spring tension in the retaining spring clip bracket in contact with the plastic covered edges of the panels.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
125 words
A light fixture for assembly without use of tools other than the hands of the assembler, comprising: a panel supporting structure; a plurality of arcuate elongated lamp shade panels each having top, bottom, right-hand and left-hand portions and each being attachable by its top portion about said panel supporting structure so as to form a continuous contiguous array of said panels; a plastic molding around the periphery of each of said arcuate elongated lamp shade panels so as to form a complete plastic casing about the edges thereof; a plurality of retaining spring clip brackets releasably attachable to said lamp shade panels at the bottom portions thereof upon said plastic casings so as to secure by friction, contiguous right-hand and left-hand portions of adjacent panels.
Claim 2
Dependent Claim
125 words
A light fixture for assembly without use of tools other than the hands of the assembler, comprising: a panel supporting structure; a plurality of arcuate elongated lamp shade panels each having top, bottom, right-hand and left-hand portions and each being attachable by its top portion about said panel supporting structure so as to form a continuous contiguous array of said panels; a plastic molding around the periphery of each of said arcuate elongated lamp shade panels so as to form a complete plastic casing about the edges thereof; a plurality of retaining spring clip brackets releasably attachable to said lamp shade panels at the bottom portions thereof upon said plastic casings so as to secure by friction, contiguous right-hand and left-hand portions of adjacent panels.
Claim 3
Dependent Claim
91 words
The light fixture of claim 1 wherein said panel supporting structure comprises: a primary flat structural member having an aperture near its center; a plurality of shelves arranged about the periphery of said flat structural member, each shelf terminating in a projection with a pin at the distal extremity thereof; a vertical offset member adjacent each said shelf and having a counter support shelf in turn adjacent each vertical offset member so that said shelves and said counter support shelves have alternate positions about the periphery of said flat structural member.
Claim 4
Dependent Claim
80 words
The light fixture of claim 2 wherein each of said plurality of retaining spring clip brackets comprises: two sections each of a generally flat-bottommed configuration of U-shaped cross-section having bent up members; a continuous bottom of said retaining spring clip bracket that joins said two sections; an obtuse bend near the latitudinal line of symmetry between said two sections tending to tilt said two sections away from each other; and at least one positioning tab formed from said continuous bottom.
Claim 5
Independent Claim
136 words
A method of assembling a light fixture comprising the steps of: selecting a panel supporting structure; applying a plastic molding about the periphery of a first arcuate elongated lamp shade panel to be attached to said supporting structure; attaching said first arcuate elongated lamp shade panel to said panel supporting structure; repeating the operation of applying a plastic molding about the periphery of a second arcuate elongated lamp shade panel; attaching said second arcuate elongated lamp shade panel to said panel supporting structure adjacent said first arcuate elongated lamp shade panel; attaching a retaining spring clip bracket to adjacent edges of said first and second arcuate elongated lamp shade panels; repeating the above steps until the full capacity of said panel supporting structure to accept attachment of said arcuate elongated lamp shade panels has been realized.
Claim 6
Independent Claim
136 words
A method of assembling a light fixture comprising the steps of: selecting a panel supporting structure; applying a plastic molding about the periphery of a first arcuate elongated lamp shade panel to be attached to said supporting structure; attaching said first arcuate elongated lamp shade panel to said panel supporting structure; repeating the operation of applying a plastic molding about the periphery of a second arcuate elongated lamp shade panel; attaching said second arcuate elongated lamp shade panel to said panel supporting structure adjacent said first arcuate elongated lamp shade panel; attaching a retaining spring clip bracket to adjacent edges of said first and second arcuate elongated lamp shade panels; repeating the above steps until the full capacity of said panel supporting structure to accept attachment of said arcuate elongated lamp shade panels has been realized.
