Abstract
Abstract An easel of the type having a generally planar material prop and a support to maintain the prop at a desired attitude. The support includes a plate which is adapted to be releasably affixed to a surface and a hinge formed of first and second members each having a base and extending legs. Each member base is secured to a different one of the prop and plate in a manner which allows a selective relative rotational movement between the base and the associated prop or plate. The axis of rotation is generally perpendicular to the associated one of the prop and plate. The legs are secured to each other in a manner which allows a selective relative pivoting movement of the members about an axis spaced from their bases.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
147 words
In an easel of the type having generally planar material prop means and means supporting said prop means at an attitude, the improvement wherein said supporting means comprises plate means adapted to be affixed to a surface and hinge means formed of first and second members each having a base and extending legs, the base of said first and second members being secured to a different one of said prop means and plate means by means for allowing a selective relative rotational movement between said member bases and said prop means and plate means about axes generally perpendicular to the associated one of said prop means and plate means, said legs being secured to each other by means for allowing a selective relative pivoting movement of said first and second members about an axis spaced from said bases, said selective relative movements providing prop means attitude reorientation.
Claim 2
Dependent Claim
147 words
In an easel of the type having generally planar material prop means and means supporting said prop means at an attitude, the improvement wherein said supporting means comprises plate means adapted to be affixed to a surface and hinge means formed of first and second members each having a base and extending legs, the base of said first and second members being secured to a different one of said prop means and plate means by means for allowing a selective relative rotational movement between said member bases and said prop means and plate means about axes generally perpendicular to the associated one of said prop means and plate means, said legs being secured to each other by means for allowing a selective relative pivoting movement of said first and second members about an axis spaced from said bases, said selective relative movements providing prop means attitude reorientation.
Claim 3
Dependent Claim
160 words
In an easel of the type having generally planar material prop means and means supporting said prop means at an attitude, the improvement wherein said supporting means comprises plate means provided with adhesion means for releasably affixing said plate means to a surface and hinge means formed of first and second generally identical U-shaped members each having a base and extending legs, the base of said first and second members being secured to a different one of said prop means and plate means by means for allowing and preventing a selective relative rotational movement between said member bases and said prop means and plate means about axes generally perpendicular to the associated one of said prop means and plate means, said legs being secured to each other by means for allowing and preventing a selective relative pivoting movement of said first and second members about an axis spaced from said bases, said selective relative movements providing prop means attitude reorientation.
Claim 4
Dependent Claim
160 words
In an easel of the type having generally planar material prop means and means supporting said prop means at an attitude, the improvement wherein said supporting means comprises plate means provided with adhesion means for releasably affixing said plate means to a surface and hinge means formed of first and second generally identical U-shaped members each having a base and extending legs, the base of said first and second members being secured to a different one of said prop means and plate means by means for allowing and preventing a selective relative rotational movement between said member bases and said prop means and plate means about axes generally perpendicular to the associated one of said prop means and plate means, said legs being secured to each other by means for allowing and preventing a selective relative pivoting movement of said first and second members about an axis spaced from said bases, said selective relative movements providing prop means attitude reorientation.
Claim 5
Dependent Claim
178 words
In an easel of the type having generally planar material prop means and means supporting said prop means at an attitude, the improvement wherein said supporting means comprises plate means adapted to be affixed to a surface and hinge means formed of first and second members each having a base and extending legs, the base of said first and second members being secured to a different one of said prop means and plate means by threaded fastener means for allowing and preventing a selective relative rotational movement between said member bases and said prop means and plate means about axes generally perpendicular to the associated one of said prop means and plate means, said legs being secured to each other by threaded fastener means for allowing and preventing a selective relative pivoting movement of said first and second members about an axis spaced from said bases, said selective relative movements providing prop means attitude reorientation and said member base associated with said prop means being selectively received adjacent to a plurality of the edges of said prop means.
Claim 6
Dependent Claim
178 words
In an easel of the type having generally planar material prop means and means supporting said prop means at an attitude, the improvement wherein said supporting means comprises plate means adapted to be affixed to a surface and hinge means formed of first and second members each having a base and extending legs, the base of said first and second members being secured to a different one of said prop means and plate means by threaded fastener means for allowing and preventing a selective relative rotational movement between said member bases and said prop means and plate means about axes generally perpendicular to the associated one of said prop means and plate means, said legs being secured to each other by threaded fastener means for allowing and preventing a selective relative pivoting movement of said first and second members about an axis spaced from said bases, said selective relative movements providing prop means attitude reorientation and said member base associated with said prop means being selectively received adjacent to a plurality of the edges of said prop means.
Claim 7
Dependent Claim
16 words
The easel of claim 3 wherein said first and second members comprise generally identical U-shaped members.
Claim 8
Dependent Claim
22 words
The easel of claim 4 wherein said plate means is provided with adhesion means for releasably affixing said plate to a surface.
Claim 9
Dependent Claim
13 words
The easel of claim 5 wherein said threaded means comprise wing nut means.
