Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
123 words
A garment rack including a single, rectangular, open frame formed of four rectilinear, hollow tube lengths joined at their ends, leg members carried at the lower corners of said frame, ground-contacting rollers depending from said leg members, shelfend members carried at the upper corners of said frame, and a plurality of rod elements extending across and above said frame and having their opposite ends received in said shelf-end members, said leg and shelf-end members each extending laterally in opposite directions from said frame and in parallel planes, and means received within the ends of said tube lengths and locking the same together, said means including adapter members joined at their ends and having integral locking portions resiliently penetrating openings in said tube lengths.
Claim 2
Dependent Claim
123 words
A garment rack including a single, rectangular, open frame formed of four rectilinear, hollow tube lengths joined at their ends, leg members carried at the lower corners of said frame, ground-contacting rollers depending from said leg members, shelfend members carried at the upper corners of said frame, and a plurality of rod elements extending across and above said frame and having their opposite ends received in said shelf-end members, said leg and shelf-end members each extending laterally in opposite directions from said frame and in parallel planes, and means received within the ends of said tube lengths and locking the same together, said means including adapter members joined at their ends and having integral locking portions resiliently penetrating openings in said tube lengths.
Claim 3
Dependent Claim
36 words
The structure of claim 1 characterized by and including aligned slots in said adapter members and said tube lengths and brackets secured to said leg members and shelf-end members, said brackets having ears penetrating said slots.
Claim 4
Dependent Claim
31 words
The structure of claim 2 wherein said adapter members and tube lengths are relatively movable after penetration of said ears to lock the same to said adapter members and tube lengths.
Claim 5
Dependent Claim
125 words
Means joining rectilinear, hollow tube lengths in angular relationship, including adapter members joined in said angular relationship, said members having a cross-sectional configuration snugly received within the tube lengths in response to manual pressure, and locking conformations on said tube lengths and members, said locking conformations being positioned for locking interengagement when said members have penetrated a desired distance into said tube lengths, said locking conformations including a lock ear yieldingly extending from each of said members and a locking slot in a wall of each of said tube lengths, said slot being positioned for entry of said ear when said members have penetrated said desired distance into said tube lengths, and alignable slots in contacting walls of said tube lengths and said adapter members.
Claim 6
Dependent Claim
125 words
Means joining rectilinear, hollow tube lengths in angular relationship, including adapter members joined in said angular relationship, said members having a cross-sectional configuration snugly received within the tube lengths in response to manual pressure, and locking conformations on said tube lengths and members, said locking conformations being positioned for locking interengagement when said members have penetrated a desired distance into said tube lengths, said locking conformations including a lock ear yieldingly extending from each of said members and a locking slot in a wall of each of said tube lengths, said slot being positioned for entry of said ear when said members have penetrated said desired distance into said tube lengths, and alignable slots in contacting walls of said tube lengths and said adapter members.
Claim 7
Dependent Claim
44 words
The struCture of claim 4 characterized by and including external elements, brackets secured to said elements and ears on said brackets, said ears being formed and adapted to penetrate said slots in said members and in said tube lengths when said slots are aligned.
Claim 8
Dependent Claim
53 words
The structure of claim 5 wherein said slots are alignable to permit penetration of said ears prior to full penetration of said members into said tube lengths, whereby further penetration of said members into said tube lengths after entry of said ears serves to lock said ears to said tube lengths and members.
Claim 9
Dependent Claim
33 words
The structure of claim 6 wherein said ears are L-shaped, the shorter leg of said ears extending through said slot, the longer leg of said ears engaging the inner surface of said members.
