Abstract
Abstract Hanging devices for pictures and the like, comprising a pair of generally triangular shaped members, each member preferably having a generally right triangle configuration with a raised hypotenuse edge having an irregular or sawtooth edge surface. The triangular members are adapted for respective attachment proximate the top corners of a picture or the like, with the irregular edge facing generally downwardly so as to engage against a pair of spaced-apart nails or other projections attached to a wall. Picture leveling can be straightforwardly accomplished by a slight lateral positioning of the picture to permit selective engagement between the nails and the sawteeth along the respective edges.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
65 words
Apparatus for hanging and leveling picture frames and the like, comprising a pair of generally triangular shaped members, each such member having means for attachment to a picture frame proximate a top rear corner comprising an edge channel adapted for nesting about said frame; each member further comprising a notched edge surface along a diagonal line which is the longest edge of said triangular shape.
Claim 2
Dependent Claim
65 words
Apparatus for hanging and leveling picture frames and the like, comprising a pair of generally triangular shaped members, each such member having means for attachment to a picture frame proximate a top rear corner comprising an edge channel adapted for nesting about said frame; each member further comprising a notched edge surface along a diagonal line which is the longest edge of said triangular shape.
Claim 3
Dependent Claim
40 words
The apparatus of claim 1, wherein said edge channel further comprises first and second sections orthogonally aligned and adapted for nesting about a frame such that the frame corner is positioned at the intersection of said channel sections' orthogonal alignment.
Claim 4
Dependent Claim
39 words
The apparatus of claim 2, wherein said generally triangular shaped members further comprise a generally right triangle shape, and said notched edge surface is formed along a line which is parallel to the hypotenuse edge of said right triangle.
Claim 5
Dependent Claim
67 words
Apparatus for hanging and leveling picture frames and the like, comprising a pair of generally triangular shaped members, each such member having means for attachment to a picture frame proximate a top rear corner comprising channel guides adapted for slidable engagement with metal picture frame sections; each member further comprising a notched edge surface along a diagonal line which is the longest edge of said triangular shape.
Claim 6
Dependent Claim
67 words
Apparatus for hanging and leveling picture frames and the like, comprising a pair of generally triangular shaped members, each such member having means for attachment to a picture frame proximate a top rear corner comprising channel guides adapted for slidable engagement with metal picture frame sections; each member further comprising a notched edge surface along a diagonal line which is the longest edge of said triangular shape.
Claim 7
Dependent Claim
45 words
The apparatus of claim 4, wherein said channel guides further comprise first and second sections orthogonally aligned and adapted for orthogonal attachment to respective picture frame sections such that the intersection of said sections corresponds to the orthogonal intersection of said first and second sections.
Claim 8
Dependent Claim
39 words
The apparatus of claim 5, wherein said generally triangular shaped members further comprise a generally right triangle shape, and said notched edge surface is formed along a line which is parallel to the hypotenuse edge of said right triangle.
Claim 9
Dependent Claim
21 words
The apparatus of claim 6, wherein said right triangle acute angles are in the range of 15 degrees to 75 degrees.
