Abstract
Abstract A drawing stencil tablet to aid a child to color and draw includes a planar stencil plate having interior openings defining tracing edges that outline a character or shape. A plurality of spaced-apart locating posts project down from an edge of the plate and engage in registering openings in a stiff planar base when the plate is placed flush against an interior area of that base so that a base margin extends all around the plate. When the locating posts are received in the base, movement of the plate relative to the base is prevented so that a child can trace or draw on a sheet of paper sandwiched between the base and the plate with assurance that the position of the stencil plate on the paper will remain fixed.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
168 words
A drawing stencil tablet comprising A. relatively rigid planar stencil plate, said plate including (1) a first set of edges extending around its periphery; (2) means defining one or more interior openings that form a second set of edges which outline one or more characters or shapes; and (3) a plurality of spaced-apart locating means projecting from the plate adjacent edges of said first set of edges and extending perpendicular to the general plane of the plate; B. a relatively stiff planar base, said base being geometrically similar to said stencil plate but of larger area so that the plate can be placed flush against an interior area of the base with a base margin extending all around the plate; and C. means defining a plurality of spaced-apart holes in the base, said holes being in register with and adapted to snugly receive, the plate locating means when the plate is against said base interior area so as to prevent movement of the plate parallel to the base.
Claim 2
Dependent Claim
168 words
A drawing stencil tablet comprising A. relatively rigid planar stencil plate, said plate including (1) a first set of edges extending around its periphery; (2) means defining one or more interior openings that form a second set of edges which outline one or more characters or shapes; and (3) a plurality of spaced-apart locating means projecting from the plate adjacent edges of said first set of edges and extending perpendicular to the general plane of the plate; B. a relatively stiff planar base, said base being geometrically similar to said stencil plate but of larger area so that the plate can be placed flush against an interior area of the base with a base margin extending all around the plate; and C. means defining a plurality of spaced-apart holes in the base, said holes being in register with and adapted to snugly receive, the plate locating means when the plate is against said base interior area so as to prevent movement of the plate parallel to the base.
Claim 3
Dependent Claim
53 words
The tablet defined in claim 1 wherein said plate comprises A. a generally rectangular frame which forms said first set of edges; and B. a plurality of guide ribs extending within said frame, said ribs being connected to each other and to the frame so as to form said second set of edges.
Claim 4
Dependent Claim
19 words
The tablet defined in claim 2 wherein said locating means are spaced apart along one edge of the frame.
Claim 5
Dependent Claim
31 words
The tablet defined in claim 3 wherein each said rib has a cross section which inclines or tapers so that the rib is narrower at its top than at its bottom.
Claim 6
Dependent Claim
18 words
The tablet defined in claim 3 wherein the locating means are short posts formed integrally with the frame.
Claim 7
Dependent Claim
23 words
The tablet defined in claim 5 and further including means defining a pair of eyes spaced apart along an edge of the frame.
Claim 8
Dependent Claim
58 words
The drawing stencil tablet defined in claim 3 and further including one or more paper sheets, said sheets A. having substantially the same dimensions as said base; and B. being sandwiched between said plate and said base in registration with said base so that, when said locating means are received in the base holes, they penetrate said sheets.
Claim 9
Dependent Claim
42 words
The drawing stencil tablet defined in claim 7 and further including means defining a plurality of spaced-apart holes in said paper sheets which are aligned with said plurality of holes in said base when said sheets are in registration with said base.
Claim 10
Dependent Claim
43 words
The drawing stencil tablet defined in claim 8 and further including markings on the upper surfaces of said plurality of sheets, said markings being in registration with said guide ribs when said stencil plate is positioned against said interior area of the base.
Claim 11
Dependent Claim
27 words
The drawing stencil tablet defined in claim 1 and further including means defining a series of spaced-apart holes extending through the base parallel to one edge thereof.
Claim 12
Dependent Claim
36 words
The drawing stencil tablet defined in claim 10 wherein the holes of said plurality of holes are located inboard on the base from and adjacent to, the holes of said series of holes through said base.
Claim 13
Dependent Claim
37 words
The drawing stencil tablet defined in claim 11 wherein the spacing of the holes in said plurality of holes and in said series of holes correspond to the spacing between the rings of a standard ring binder.
Claim 14
Dependent Claim
30 words
The drawing stencil tablet defined in claim 9 wherein A. said base is a sheet of relatively thick cardboard; and B. said stencil plate is a unitary molded plastic part.
Claim 15
Dependent Claim
58 words
The drawing stencil tablet defined in claim 13 and further including one or more paper sheets, said sheets A. having substantially the same dimensions as said base; and B. being sandwiched between said plate and said base in registration with said base so that, when said locating means are received in the base holes, they penetrate said sheets.
