Abstract
Abstract An optic art kit is disclosed comprising one or more pieces of a pre-cut frame material (a section of which is constructed with an internal light source), a sheet of abradable material, a one scriber having engraving and abrasive portions, several triangular supports for freestanding assembly, and line drawings or other pictorial material for use as a pattern when abrading the sheet material. The pre-cut frame material is extruded from plastic and has a flat base, substantially perpendicular side portions and rounded top portions which terminate in parallel spaced apart clamping flanges which engage opposing sides of the sheet material. This frame material is preferably mitered so that it may adhere to all the edges of the sheet material to frame the sheet or, alternatively, to cooperate with one or more triangular supports to create a freestanding assembly. The resulting kit produces a professional, attractive edge-lit product which may be used for decoration or to provide information.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
163 words
An optic art kit comprising: (a) a light transmitting, abradable sheet material; (b) fluorescent illumination means for transmitting light to the edge of said sheet, said fluorescent illumination means being cylindrical and having a remote ballast, and (c) an extruded framing means having a base of sufficient length to mount said illuminating means thereon, a width slightly greater than the outside diameter of said illuminating means, sidewalls extending along the lengthwise edge of said base, said sidewalls having a length slightly greater than the radius of the illuminating means, arcs depending from said sidewalls and remote from said base, said arcs being concentric with respect to the longitudinal axis of said fluorescent illumination means and extending inwardly from the planes defined by said sidewalls, and vertically disposed flanges extending from the free ends of said arcs substantially parallel to said sidewalls, for substantially surrounding said fluorescent illumination means and for receiving and retaining said sheet in close proximity to said fluorescent illumination means.
Claim 2
Dependent Claim
163 words
An optic art kit comprising: (a) a light transmitting, abradable sheet material; (b) fluorescent illumination means for transmitting light to the edge of said sheet, said fluorescent illumination means being cylindrical and having a remote ballast, and (c) an extruded framing means having a base of sufficient length to mount said illuminating means thereon, a width slightly greater than the outside diameter of said illuminating means, sidewalls extending along the lengthwise edge of said base, said sidewalls having a length slightly greater than the radius of the illuminating means, arcs depending from said sidewalls and remote from said base, said arcs being concentric with respect to the longitudinal axis of said fluorescent illumination means and extending inwardly from the planes defined by said sidewalls, and vertically disposed flanges extending from the free ends of said arcs substantially parallel to said sidewalls, for substantially surrounding said fluorescent illumination means and for receiving and retaining said sheet in close proximity to said fluorescent illumination means.
Claim 3
Dependent Claim
24 words
The invention of claim 1 wherein said kit further comprises abrading means for altering the light transmitting characteristics of the surface of said sheet.
Claim 4
Dependent Claim
46 words
The invention of claim 2 wherein said abrading means further comprises engraving means for scribing into said surface and abrasive means for roughening said surface, whereby, when edge illuminated, said engraving means defines lines in said surface and said abrasive means defines shading on said surface.
Claim 5
Dependent Claim
31 words
The invention of claim 3 wherein said abrading means comprises the body of a mechanical-pencil fitted at one end with a hardened needle and at the other with an eraser material.
Claim 6
Dependent Claim
35 words
The invention of claim 1 wherein said flanges are parallel and symmetrically disposed with respect to a plane which is perpendicular to said base portion and intersects the longitudinal axis of said fluorescent illumination means.
Claim 7
Dependent Claim
22 words
The invention of claim 5 wherein said flanges are normally spaced apart by a distance less than the thickness of said sheet.
Claim 8
Dependent Claim
14 words
The invention of claim 6 wherein said frame is extruded from a thermoplastic material.
Claim 9
Dependent Claim
15 words
The invention of claim 7 wherein said thermoplastic material is re-ground, plastic battery case material.
Claim 10
Dependent Claim
44 words
The invention of claim 8 wherein said framing means comprises a plurality of frame sections of identical cross-sections, each of which sections is mitered to form a continuous self-adhering frame when applied to the sides of an appropriately sized piece of said sheet material.
Claim 11
Dependent Claim
36 words
The invention of claim 8 wherein said kit further comprises support means for engaging ends of said framing means and portions of opposing surfaces of said sheet material, for facilitating freestanding display of edge-lit sheet material.
Claim 12
Dependent Claim
44 words
The invention of claim 10 wherein said support means comprises at least one substantially triangular piece of said sheet material, said piece being slotted to slidingly receive at least a portion of said sheet material to receive edge lighting from said fluorescent illumination means.
Claim 13
Dependent Claim
23 words
The invention of claim 1 wherein said fluorescent illumination means and said remote ballast are electrically interconnected by conduit means and switch means.
Claim 14
Dependent Claim
46 words
The invention of claim 12 wherein said conduit means comprises at least two conduits extending longitudinally along the length of said fluorescent illumination means, within spaced apart basal conduit channels defined between said fluorescent illumination means and portions of the interior surface of said framing means.
Claim 15
Dependent Claim
35 words
The invention of claim 12 wherein said switch means comprises a normally open, momentary contact switch mounted between an end of said fluorescent illumination means and an end of a portion of said framing means.
Claim 16
Dependent Claim
35 words
The invention of claim 12 wherein said switch means comprises a normally closed, momentarily openable, switch mounted between an end of said fluorescent illumination means and an end of a portion of said framing means.
