Abstract
Abstract An apparatus is disclosed, as for use by an artist, which may be reduced to a compact unit and which opens for use with a photographic projector, to provide a support surface, upon which a photographic image is projected and a canvas or other medium is supported. The unit incorporates a platform for receiving the projector, terminated at one end by a hinged, working-surface member incorporating a glass panel, and terminated at the other end by a reflective structure. In use, an image may be projected to a desired size (by the use of the reflective structure) to appear upon the working surface and upon which an artist''s medium is supported. The platform member, working-surface member and reflective structure are hinge mounted to be folded into parallel-plane relationship thereby reducing the structure to a compact closed unit.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
179 words
An artist''s aid apparatus embodied in a closable unit, for use with a photographic projector, comprising: a frame structure including a flat base to receive said projector and further including affixed normally extending first edges; a working-surface member having normally extending second edges and including a rigid, light-transmissive work panel and a smaller light transmissive viewing panel; hinge means for affixing said working-surface member to said frame structure in folding relationship, whereby to accommodate open and closed positional relationships; a reflective structure having normally extending third edges and including a reflective surface for receiving a light image from said projector and reflecting said light image to said workingsurface member; hinge means for affixing said reflective structure to said frame structure opposed to said working-surface member whereby to accommodate open and closed positional relationships and whereby said reflective structure is in parallel faced opposing relationship to said working surface member, upon each of said members being open; and means for fixing said frame structure, said working-surface member and said reflective structure closed in coplanar relationship by said edges abutting together.
Claim 2
Dependent Claim
179 words
An artist''s aid apparatus embodied in a closable unit, for use with a photographic projector, comprising: a frame structure including a flat base to receive said projector and further including affixed normally extending first edges; a working-surface member having normally extending second edges and including a rigid, light-transmissive work panel and a smaller light transmissive viewing panel; hinge means for affixing said working-surface member to said frame structure in folding relationship, whereby to accommodate open and closed positional relationships; a reflective structure having normally extending third edges and including a reflective surface for receiving a light image from said projector and reflecting said light image to said workingsurface member; hinge means for affixing said reflective structure to said frame structure opposed to said working-surface member whereby to accommodate open and closed positional relationships and whereby said reflective structure is in parallel faced opposing relationship to said working surface member, upon each of said members being open; and means for fixing said frame structure, said working-surface member and said reflective structure closed in coplanar relationship by said edges abutting together.
Claim 3
Dependent Claim
33 words
An apparatus according to claim 1 further including a mirror structure slidably affixed to said flat base of said frame structure to be variously positioned, generally in the plane of said reflective structure.
Claim 4
Dependent Claim
29 words
An apparatus according to claim 2 wherein said reflective structure includes first and second mirrors for use with said mirror structure to project an image on said light-transmissive panel.
Claim 5
Dependent Claim
24 words
An apparatus according to claim 2 wherein said working-surface member further includes a protective sheet hinged thereto for movement to shield said light-transmissive panel.
Claim 6
Dependent Claim
22 words
An apparatus according to claim 1 wherein said reflective structure includes support means for supporting said reflective surface in various relationships thereto.
Claim 7
Dependent Claim
53 words
An apparatus according to claim 2 further including a mirror structure slidably affixed to said frame structure to be variously positioned, generally in the plane of said reflective structure and wherein said reflective structure includes first and second mirrors for use with said mirror structure to project an image on said light-transmissive panel.
Claim 8
Dependent Claim
41 words
An apparatus according to claim 6 wherein said working-surface member further includes a protective sheet hinged thereto for movement to shield said light-transmissive panel and wherein said reflective structure includes support means for supporting said reflective surface in various relationships thereto.
