Abstract
Abstract In a hanging file assembly having a pair of rails with generally C-shaped fastening clips disposed thereon. Locking rods in parallelism with the rails are provided with recesses, and when the fastening clips are urged into and seat in the recesses, such rails and rods form the basic structure of the hanging file assembly. A support member having cutout portions is adapted to fit into slots provided in the rods so as to add to the rigidity of the total assembly. The recesses are provided with a keyway having at least one sloping surface to insure for positive locking as between the rails and the rods.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
162 words
A hanging file assembly comprising a plurality of juxtapositioned horizontally disposed cooperative members positionable to form a secure upright structure including: rail means; locking rod means; unitary locking means in communication with said rail means and said locking rod means; said locking rod means having channel means defined by wall surfaces adapted to engage said unitary locking means; said unitary locking means being an integrally formed structure having a first portion disposed about said rail means and a second portion contiguous with said first portion, being offset therefrom by projection means extending from said first portion; said second portion being pivotally connected to said locking rod means, whereby rotation of said locking rod means into a vertical position causes engagement between said projection means and said wall surfaces within said channel means, forming a secure joint between between said locking rod means and said rail means; and cross support bar means adapted to engage slot means provided in said locking rod means.
Claim 2
Dependent Claim
162 words
A hanging file assembly comprising a plurality of juxtapositioned horizontally disposed cooperative members positionable to form a secure upright structure including: rail means; locking rod means; unitary locking means in communication with said rail means and said locking rod means; said locking rod means having channel means defined by wall surfaces adapted to engage said unitary locking means; said unitary locking means being an integrally formed structure having a first portion disposed about said rail means and a second portion contiguous with said first portion, being offset therefrom by projection means extending from said first portion; said second portion being pivotally connected to said locking rod means, whereby rotation of said locking rod means into a vertical position causes engagement between said projection means and said wall surfaces within said channel means, forming a secure joint between between said locking rod means and said rail means; and cross support bar means adapted to engage slot means provided in said locking rod means.
Claim 3
Dependent Claim
52 words
A hanging file assembly as claimed in claim 1, wherein: said first portion being generally C-shaped; said projection means being offset from said first portion in a plane normal thereto; said second portion being flange means extending from the ends of said projection means in a plane parallel to said first portion.
Claim 4
Dependent Claim
35 words
A hanging file assembly as claimed in claim 2, wherein: said flange means are disposed in offset relation with respect to said first portion for a distance equal to the width of said projection means.
Claim 5
Dependent Claim
49 words
A hanging file assembly as claimed in claim 2, wherein: said projection means and said flange means form a plurality of contact surfaces whereby, the distance between adjacent wall surfaces defined by said first portion and said flange means is less than the width of said locking rod means.
Claim 6
Dependent Claim
99 words
A hanging file assembly as claimed in claim 1, wherein: said second portion includes a pair of oppositely directed extending surfaces disposed in a plane parallel to said first portion having connecting means for pivotally affixing said locking rod means to said first portion, whereby rotation of said locking rod means into the vertical portion urges said projection means to cooperatively seat within said channel means, thereby causing said rail means and said locking rod means to be positively affixed with respect to one another in response to forces transmitted by said locking rod means and said projection means.
Claim 7
Dependent Claim
41 words
A hanging file assembly as claimed in claim 1, wherein: said projection means includes a pair of integrally formed parallel members, said first portion being resilient to thereby enable said parallel members to pass into and seat within said channel means.
Claim 8
Dependent Claim
55 words
A hanging file assembly as claimed in claim 1, wherein: said rail means being disposed in parallel abutting relation with respect to said locking rod means and offset by a distance sufficient to permit rotation of said locking rod means about a pivot point defined by said unitary locking means on said locking rod means.
Claim 9
Dependent Claim
86 words
A hanging file assembly as claimed in claim 1, wherein: said unitary locking means comprises a generally ''''C'''' shaped resilient member provided with space to seat said rail means; a pair of oppositely oriented flange members contiguous therewith and extending from said projection means, thereby providing a plurality of contact surfaces for engaging said rail means and said locking rail means in an area defined by respective contact surfaces of inner and outer end portions of said resilient member, said projection means and said flange members.
Claim 10
Dependent Claim
54 words
A hanging file assembly as claimed in claim 1, wherein: said channel means are defined by A keyway passage formed in said locking rod means having first and second non-parallel entrance wall surfaces contiguous therewith and merging into a circular recess, enabling the passage of said projection means for seating within said circular recess.
Claim 11
Dependent Claim
25 words
A hanging file assembly as claimed in claim 9, wherein: said first wall surface is defined by an acute angle with respect to the horizontal.
Claim 12
Dependent Claim
23 words
A hanging file assembly as claimed in claim 9, wherein: said second wall surface is inclined at 45* with respect to the horizontal.
