Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
94 words
A lock-up corner bracket for frame parts, comprising (a) the bracket having legs that extend in planes which define a corner angle, (b) the legs having terminal enlargements that are elongated in parallel directions of forward insertion of the legs relatively into recesses formed in said parts, for retaining said parts in assembled relation, (c) said enlargements being columnar, (d) the forwardmost end portions of said legs and columnar enlargements being forwardly tapered, (e) said tapered end portions of the legs and columnar enlargements terminating in a flat plane normal to said parallel directions.
Claim 2
Dependent Claim
94 words
A lock-up corner bracket for frame parts, comprising (a) the bracket having legs that extend in planes which define a corner angle, (b) the legs having terminal enlargements that are elongated in parallel directions of forward insertion of the legs relatively into recesses formed in said parts, for retaining said parts in assembled relation, (c) said enlargements being columnar, (d) the forwardmost end portions of said legs and columnar enlargements being forwardly tapered, (e) said tapered end portions of the legs and columnar enlargements terminating in a flat plane normal to said parallel directions.
Claim 3
Dependent Claim
16 words
The corner bracket of claim 1 wherein said columnar enlargements have lengths equal to leg length.
Claim 4
Dependent Claim
13 words
The corner bracket of claim 1 wherein said corner angle is about 90°.
Claim 5
Dependent Claim
14 words
The corner bracket of claim 1 wherein said enlargements have generally cylindrical outer surfaces.
Claim 6
Dependent Claim
21 words
The combination of claim 1 including multiple brackets as defined interconnecting picture frame parts at each corner of the picture frame.
Claim 7
Dependent Claim
33 words
The combination that includes the corner bracket of claim 1 and said frame parts, the bracket legs received into said recesses which are formed to closely slidably receive said legs including said enlargements.
Claim 8
Dependent Claim
13 words
The combination of claim 6 wherein said frame parts are picture frame lengths.
Claim 9
Dependent Claim
93 words
A lock-up corner bracket for frame parts, comprising (a) the bracket having legs that extend in planes which define a corner angle, (b) the legs having terminal enlargements that are elongated in parallel directions of forward insertion of the legs relatively into recesses formed in said parts, for retaining said parts in assembled relation, (c) said enlargements being columnar, (d) and including a barb on at least one leg and which projects relatively outwardly to engage one of said parts to resist relatively rearward removal of said bracket leg from said one part.
Claim 10
Dependent Claim
93 words
A lock-up corner bracket for frame parts, comprising (a) the bracket having legs that extend in planes which define a corner angle, (b) the legs having terminal enlargements that are elongated in parallel directions of forward insertion of the legs relatively into recesses formed in said parts, for retaining said parts in assembled relation, (c) said enlargements being columnar, (d) and including a barb on at least one leg and which projects relatively outwardly to engage one of said parts to resist relatively rearward removal of said bracket leg from said one part.
Claim 11
Dependent Claim
82 words
A lock-up corner bracket for frame parts, comprising (a) the bracket having legs that extend in planes which define a corner angle, (b) the legs having terminal enlargements that are elongated in parallel directions of forward insertion of the legs relatively into recesses formed in said parts, for retaining said parts in assembled relation, (c) said enlargements being columnar, (d) and including barbs on said legs and which project relatively outwardly to resist relatively rearward removal of said legs from said parts.
Claim 12
Dependent Claim
82 words
