Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
275 words
An easel backed frame for displaying and supporting a photograph or the like comprising: a. a rectangular frame comprising a panel which is centrally apertured to provide a window through which a photograph or the like placed behind said panel may be seen; b. an easel back comprising: i. a rectangular first substantially planar member having a perimeter coextensive with said frame and attached to said frame; ii. a first slit in said first planar member parallel to a first edge thereof and extending approximately ninety percent of the distance between the edges thereof forming said first edge; iii. a second slit in said first planar member said second slit comprising two obliquely intersecting slashes, the first of said two slashes being generally perpendicular to, but not intersecting said first slit, the intersection of said two slashes being approximately two-thirds of the perpendicular distance from said first edge of said first planar member; iv. a triangular second planar member, one edge of which is hinged to and coextensive with said first edge of said first planar member; v. a triangular third planar member, one edge of which is hinged to and coextensive with one edge of said second planar member other than its edge which is coextensive with said first edge of said first planar member; and vi. a fourth planar member, one edge of which is hinged to and common with a part of one edge of said third planar member other than its edge which is common with said second planar member, a portion of which is engageable with said second slit thereby forming a rigid structure capable of supporting a picture frame.

An easel backed frame for displaying and supporting a photograph or the like comprising: a. a rectangular frame comprising a panel which is centrally apertured to provide a window through which a photograph or the like placed behind said panel may be seen; b. an easel back comprising: i. a rectangular first substantially planar member having a perimeter coextensive with said frame and attached to said frame; ii. a first slit in said first planar member parallel to a first edge thereof and extending approximately ninety percent of the distance between the edges thereof forming said first edge; iii. a second slit in said first planar member said second slit comprising two obliquely intersecting slashes, the first of said two slashes being generally perpendicular to, but not intersecting said first slit, the intersection of said two slashes being approximately two-thirds of the perpendicular distance from said first edge of said first planar member; iv. a triangular second planar member, one edge of which is hinged to and coextensive with said first edge of said first planar member; v. a triangular third planar member, one edge of which is hinged to and coextensive with one edge of said second planar member other than its edge which is coextensive with said first edge of said first planar member; and vi. a fourth planar member, one edge of which is hinged to and common with a part of one edge of said third planar member other than its edge which is common with said second planar member, a portion of which is engageable with said second slit thereby forming a rigid structure capable of supporting a picture frame.
Claim 3
Dependent Claim
34 words
The invention of claim 1 wherein said members of said easel back are all formed integrally with one another with the hinges being in the form of scorelines for localized bending between the members.
Claim 4
Dependent Claim
30 words
The invention of claim 2 wherein said substantially planar first member contains a depression contiguous to said second slit, said depression coacting with said second slit to form a pocket.
