Abstract
Abstract This invention relates to a frame assembly for mounting a planar member such as a picture or other article of art work. The frame assembly includes: a peripheral wall having a plurality of interconnected wall sections, connecting members for interconnecting the wall sections, and hanger members for supporting the frame assembly. Each of the wall sections may include a first channel and a second channel, the first channel being adapted to receive the connecting members and the second channel being adapted to receive the hanger members. The connecting members include a pair of angularly related leg members having a generally planar surface integral protrusion means protruding from the planar surface for frictionally engaging the sides of the channel, the protrusion means including pointed tab members extending out of the planar surface and pointing toward the juncture between the leg members for biting engagement with the sides of the channels to resist separation of the wall sections.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
153 words
A frame assembly for mounting a planar member comprising: a peripheral wall including a plurality of interconnected wall sections, each of said wall sections having at least one longitudinal channel, and connecting members for interconnecting said wall sections adapted for location within said channels; said connecting members including a pair of angularly related leg members having a generally planar surface, and integral protrusion means protruding from said planar surfaces for frictionally engaging the sides of said channels, said protrusion means including pointed tab members extending out of said planar surface and pointing toward the juncture between said leg members for biting engagement with the sides of said channels and depressed areas extending out of said planar surface of said leg members in a direction opposite to at least one of said tab members, said depressed areas and said tab members simultaneously urging one another into anchoring engagement with the sides of said channels.
Claim 2
Dependent Claim
153 words
A frame assembly for mounting a planar member comprising: a peripheral wall including a plurality of interconnected wall sections, each of said wall sections having at least one longitudinal channel, and connecting members for interconnecting said wall sections adapted for location within said channels; said connecting members including a pair of angularly related leg members having a generally planar surface, and integral protrusion means protruding from said planar surfaces for frictionally engaging the sides of said channels, said protrusion means including pointed tab members extending out of said planar surface and pointing toward the juncture between said leg members for biting engagement with the sides of said channels and depressed areas extending out of said planar surface of said leg members in a direction opposite to at least one of said tab members, said depressed areas and said tab members simultaneously urging one another into anchoring engagement with the sides of said channels.
Claim 3
Dependent Claim
57 words
An assembly as set forth in claim 1 including spring means for holding the planar member within said assembly, said spring means including an elongated, resilient arcuate portion and extension means disposed at each end thereof, a portion of which extends into one of said channels whereby said arcuate portion is adapted to engage the planar member.
Claim 4
Dependent Claim
37 words
An assembly as set forth in claim 2 wherein said extension means includes first and second ear portions, said first ear portion being longer than said second ear portion and adapted to extend into said first channel.
Claim 5
Dependent Claim
31 words
An assembly as set forth in claim 3 wherein said wall sections include an inwardly extending flange for coacting with said spring means for holding the planar member within said assembly.
Claim 6
Dependent Claim
21 words
An assembly as set forth in claim 4 including four wall sections wherein said wall sections define a rectangular frame assembly.
Claim 7
Dependent Claim
31 words
An assembly as set forth in claim 1 wherein said tab members are generally triangular and extend out of said planar surface of said leg members along the lateral edges thereof.
Claim 8
Dependent Claim
41 words
An assembly as set forth in claim 1 including a pair of hangar members for supporting said frame assembly said hangar members being slidably disposed in the channels of oppositely located wall sections, and positioning means for positioning said hangar members.
Claim 9
Dependent Claim
44 words
An assembly as set forth in claim 7 wherein said hangar members include a first portion slidably disposed within a channel and a second portion extending substantially perpendicularly from said first portion, said second portion including eyelet means for securing a flexible cable thereto.
Claim 10
Dependent Claim
22 words
An assembly as set forth in claim 7 wherein said positioning means comprises a strip of stiff material disposed in said channels.
