US4027404A — Paint set and teaching aid

Claim 1

Independent Claim 327 words

A color pigment paint teaching set comprising a base including a generally flat, circular central portion having a circular array of equi-angularly spaced, flat-bottomed recesses adapted to receive replaceable compressed pads containing pigments, said circular array of recesses normally receiving pads of progressively different colors in the color spectrum, said base being continuously bounded by an integral circumferential flange extending rearwardly from the plane of said central portion and having a plurality of substantially flat, individual tab members generally parallel to the plane of said central portion, integral with said flange and extending radially outward therefrom; and a resiliently firm cover having a transparent, circular central window portion rotatively overlaying said central portion so as to be parallel to but displaced forwardly thereof, said cover further having a rearwardly extending cylindrical flange adapted to be slideably received over said base flange and to be frictionally engaged thereby, said cylindrical flange including a relatively flat annular lip portion disposed adjacent the end thereof, said lip portion being substantially parallel to said window portion and being adapted to be slideably disposed against said tab members for rotation thereover, the cylindrical flange and annular lip portion of said cover cooperably engaging the rearwardly extending flange and tab members of said base such that said cover is normally retainably received over said base for rotation with respect thereto while simultaneously being frictionally retained thereover but such that said cover may be separated from said base and removed therefrom by the simultaneous application of manual force to said lip portion in a first direction generally toward said window portion and to at least one of said tab members in the opposite direction so as to overcome the frictional attachment and effect separation, said window portion of said cover including predetermined sets of distinctively and differently lined visible selector indicia viewable from above in juxtaposition relative to the differently colored pads for aiding in selecting, combining and balancing the colors of the spectrum.

Claim 2

Dependent Claim 327 words

A color pigment paint teaching set comprising a base including a generally flat, circular central portion having a circular array of equi-angularly spaced, flat-bottomed recesses adapted to receive replaceable compressed pads containing pigments, said circular array of recesses normally receiving pads of progressively different colors in the color spectrum, said base being continuously bounded by an integral circumferential flange extending rearwardly from the plane of said central portion and having a plurality of substantially flat, individual tab members generally parallel to the plane of said central portion, integral with said flange and extending radially outward therefrom; and a resiliently firm cover having a transparent, circular central window portion rotatively overlaying said central portion so as to be parallel to but displaced forwardly thereof, said cover further having a rearwardly extending cylindrical flange adapted to be slideably received over said base flange and to be frictionally engaged thereby, said cylindrical flange including a relatively flat annular lip portion disposed adjacent the end thereof, said lip portion being substantially parallel to said window portion and being adapted to be slideably disposed against said tab members for rotation thereover, the cylindrical flange and annular lip portion of said cover cooperably engaging the rearwardly extending flange and tab members of said base such that said cover is normally retainably received over said base for rotation with respect thereto while simultaneously being frictionally retained thereover but such that said cover may be separated from said base and removed therefrom by the simultaneous application of manual force to said lip portion in a first direction generally toward said window portion and to at least one of said tab members in the opposite direction so as to overcome the frictional attachment and effect separation, said window portion of said cover including predetermined sets of distinctively and differently lined visible selector indicia viewable from above in juxtaposition relative to the differently colored pads for aiding in selecting, combining and balancing the colors of the spectrum.

Claim 3

Dependent Claim 77 words

The paint teaching set of claim 1 further characterized in that said base includes an annular rim raised above the plane of said central portion and integral with said central portion and said rearwardly extending flange, said raised rim encircling the radial periphery of said central portion for providing a sliding surface adapted for engagement with the inside radially peripheral surface of said window portion to facilitate the rotation of said cover with respect to said base.

Claim 4

Dependent Claim 118 words

The paint teaching set of claim 1 further characterized in that the radially inner surface of the cover flange includes a plurality of circumferentially spaced, radially inwardly facing frictional protrusions and in that said rearwardly extending base flange has the radially outer surface adjacent said central portion flaring radially outward as it extends rearwardly therefrom and the radially outer surface adjacent the end of said base flange tapering radially inward as it extends toward said end so as to form an annular ridged portion around the outer surface of said flange which is adapted to frictionally engage the protrusions of the inside surface of the cylindrical flange of said cover to normally prevent separation while permitting cover rotation.

Claim 5

Dependent Claim 92 words

The paint teaching set of claim 3 further characterized in that the flare of said surface adjacent said central portion makes an acute angle of less than 5° with respect to an axis normal to the plane of said central portion, and the taper of said surface adjacent the end of said base flange makes a greater acute angle with respect to said axis such that when said cover is normally positioned over said base, said protrusions freely ride in the recess created by the inwardly tapered surface to minimize rotational friction.

Claim 6

Dependent Claim 185 words

The paint teaching set of claim 1 further characterized in that there are 3N of said spaced recesses where "N" is an even number and in that said cover panel is provided with four sets of said selector indicia, the first set being shaped like an equilateral triangle whose apices serve as a triadic indicator to point out three equally-spaced colors of the spectrum, the second set being in the form of a straight line to serve as a complement indicator such that one end points out the color in the spectrum which is the complement of the color at the opposite end thereof, the third set being Y-shaped and serving as a split complementary indicator such that the top of the "Y" points out the two colors from the color spectrum which diametrically balance an intermediate color whose complement is pointed out by the bottom of the "Y", and the fourth set being three radially-extending line indicators angularly spaced to point to adjacent colors to serve as an analogous color indicator so as to point out three adjacent colors which will provide quiet harmony.

Claim 7

Dependent Claim 38 words

The paint teaching set of claim 5 wherein "N"=4 and wherein indicia are provided on the surface of said central portion adjacent each of said recesses for indicating which of said colored pads is to be placed therein.

Claim 8

Dependent Claim 76 words

The paint teaching set of claim 1 wherein the plane of the flat bottoms of said recesses is substantially parallel to the plane of the lower surface of said tab members but spaced inwardly therefrom toward said central portion and wherein the outer rim of the base flange is planar with said lower surface of said tab members such that said outer rim and said tab members serve to support said paint set on a surface.
