Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
160 words
A one-piece picture frame comprising a front wall having an opening therein to expose a picture mounted in the frame, a plurality of side walls on said front wall along the periphery thereof and extending rearwardly therefrom, a hook on one of said side walls near the rear thereof and having a forwardly-extending tongue spaced from said one side wall and disposed generally parallel thereto, at least a portion of one of said side walls having a rearwardly-facing channel of a width approximately equal to the thickness of said tongue, whereby said tongue is removably insertable in the channel of another similarly constructed picture frame for frictional engagement in the channel to enable interconnection of the two frames, said tongue having a forwardly extending slit therein to enable lateral compression of the tongue while being inserted in the associated channel, the tendency of said tongue to return to its uncompressed state assisting in holding the tongue in its associated channel.
Claim 2
Dependent Claim
160 words
A one-piece picture frame comprising a front wall having an opening therein to expose a picture mounted in the frame, a plurality of side walls on said front wall along the periphery thereof and extending rearwardly therefrom, a hook on one of said side walls near the rear thereof and having a forwardly-extending tongue spaced from said one side wall and disposed generally parallel thereto, at least a portion of one of said side walls having a rearwardly-facing channel of a width approximately equal to the thickness of said tongue, whereby said tongue is removably insertable in the channel of another similarly constructed picture frame for frictional engagement in the channel to enable interconnection of the two frames, said tongue having a forwardly extending slit therein to enable lateral compression of the tongue while being inserted in the associated channel, the tendency of said tongue to return to its uncompressed state assisting in holding the tongue in its associated channel.
Claim 3
Dependent Claim
151 words
A one-piece picture frame comprising a front wall having an opening therein to expose a picture mounted in the frame, a plurality of side walls on said front wall along the periphery thereof and extending rearwardly therefrom, a hook on one of said side walls near the rear thereof and having a forwardly extending tongue spaced from said one side wall and disposed generally parallel thereto, at least a portion of one of said side walls having a rearwardly facing channel of a width approximately equal to the thickness of said tongue, whereby said tongue is removably insertable in the channel of another similarly constructed picture frame for frictional engagement in the channel to enable interconnection of the two frames, and a protuberance on said tongue and an indentation on the associated surface in said channel, said protuberance snap-fitting into said indentation upon insertion of said tongue in the associated channel.
Claim 4
Dependent Claim
151 words
A one-piece picture frame comprising a front wall having an opening therein to expose a picture mounted in the frame, a plurality of side walls on said front wall along the periphery thereof and extending rearwardly therefrom, a hook on one of said side walls near the rear thereof and having a forwardly extending tongue spaced from said one side wall and disposed generally parallel thereto, at least a portion of one of said side walls having a rearwardly facing channel of a width approximately equal to the thickness of said tongue, whereby said tongue is removably insertable in the channel of another similarly constructed picture frame for frictional engagement in the channel to enable interconnection of the two frames, and a protuberance on said tongue and an indentation on the associated surface in said channel, said protuberance snap-fitting into said indentation upon insertion of said tongue in the associated channel.
Claim 5
Dependent Claim
147 words
A one-piece picture frame comprising a front wall having an opening therein to expose a picture mounted in the frame, a plurality of side walls on said front wall along the periphery thereof and extending rearwardly therefrom, a hook on one of said side walls near the rear thereof and having a forwardly extending tongue spaced from said one side wall and disposed generally parallel thereto, at least a portion of one of said side walls having a rearwardly facing channel of a width approximately equal to the thickness of said tongue, whereby said tongue is removably insertable in the channel of another similarly-constructed picture frame for frictional engagement in the channel to enable interconnection of the two frames, said tongue tapering in thickness from a relatively thick rear end to a relatively thin forward end, thereby to facilitate entry of the tongue into the associated channel.
Claim 6
Dependent Claim
147 words
A one-piece picture frame comprising a front wall having an opening therein to expose a picture mounted in the frame, a plurality of side walls on said front wall along the periphery thereof and extending rearwardly therefrom, a hook on one of said side walls near the rear thereof and having a forwardly extending tongue spaced from said one side wall and disposed generally parallel thereto, at least a portion of one of said side walls having a rearwardly facing channel of a width approximately equal to the thickness of said tongue, whereby said tongue is removably insertable in the channel of another similarly-constructed picture frame for frictional engagement in the channel to enable interconnection of the two frames, said tongue tapering in thickness from a relatively thick rear end to a relatively thin forward end, thereby to facilitate entry of the tongue into the associated channel.
