Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
108 words
A cabinet for storing oversize documents without folding, comprising: a cabinet frame including a back mounting and a pair of cabinet ends having guide channels formed therein; a flexible drawer mounted on said frame movable in said channels between a curled position storing said documents in a loosely curled state and an open position extending outwardly from the cabinet supporting said documents thereon in a flat state for easy viewing and selection; inner document retaining means on said drawer for maintaining said documents in said loosely curled state in said closed position; and outer document retaining means for retaining said documents on said drawer in said open position.
Claim 2
Dependent Claim
108 words
A cabinet for storing oversize documents without folding, comprising: a cabinet frame including a back mounting and a pair of cabinet ends having guide channels formed therein; a flexible drawer mounted on said frame movable in said channels between a curled position storing said documents in a loosely curled state and an open position extending outwardly from the cabinet supporting said documents thereon in a flat state for easy viewing and selection; inner document retaining means on said drawer for maintaining said documents in said loosely curled state in said closed position; and outer document retaining means for retaining said documents on said drawer in said open position.
Claim 3
Dependent Claim
36 words
The cabinet according to claim 1 wherein said outer document retaining means is a raised structural element which also functions as a handle to permit manual movement of said drawer between said open and closed positions.
Claim 4
Dependent Claim
47 words
The cabinet according to claim 1 wherein said guide channels are wider at their mid portion than at their ends whereby during opening, the outer edges of the channels guide the drawer while on closing the inner edges of said channels prevent the drawer from curling excessively.
Claim 5
Dependent Claim
36 words
The cabinet according to claim 1 wherein said drawer in the open position is supported on a drawer support and cantilevers out to an extended position beyond the frame to permit access to the stored documents.
Claim 6
Dependent Claim
21 words
The cabinet according to claim 1 wherein said drawer in the closed curled position forms a protective cover about the documents.
Claim 7
Dependent Claim
65 words
The cabinet according to claim 4 wherein said drawer support is flexible and comprises a resilient cord positioned beneath said drawer and attached to said cabinet ends, said cord supporting said drawer in the open position in a manner so as to permit the center of the drawer to sag, thereby to produce the cantilever action which extends the drawer linearly outwardly from the cabinet.
Claim 8
Dependent Claim
65 words
The cabinet according to claim 4 wherein said drawer support is rigid and comprises a contoured member positioned beneath said drawer and attached to said cabinet ends, said member supporting said drawer in the open position in a manner so as to permit the center of the drawer to sag, thereby to produce the cantilever action which extends the drawer linearly outwardly from the cabinet.
Claim 9
Dependent Claim
87 words
A cabinet for storing and displaying oversize documents, comprising: a. a back mounting for attachment to a wall; b. a pair of cabinet ends attached to said back mounting each end having a guide channel formed therein and a pivot pin extending therefrom; and c. a flexible drawer having an end guide attached to one end and a drawer pull attached to the other end, said drawer supported on said pivot pins and movable between a cantilevered display position and a curled storage position protecting said documents.
Claim 10
Dependent Claim
87 words
A cabinet for storing and displaying oversize documents, comprising: a. a back mounting for attachment to a wall; b. a pair of cabinet ends attached to said back mounting each end having a guide channel formed therein and a pivot pin extending therefrom; and c. a flexible drawer having an end guide attached to one end and a drawer pull attached to the other end, said drawer supported on said pivot pins and movable between a cantilevered display position and a curled storage position protecting said documents.
Claim 11
Dependent Claim
38 words
A cabinet according to claim 8 wherein said cabinet further includes flexible tensioning means connecting said end guide to said drawer pull to limit the extension of said drawer and to support said drawer in the display position.
Claim 12
Dependent Claim
32 words
A cabinet according to claim 8 wherein said guide channel is serrated along a lower portion thereof to reduce surface friction during movement of said drawer between said storage and display positions.
Claim 13
Dependent Claim
27 words
A cabinet according to claim 8 further including a drawer support attached to said drawer and extending transversely thereon to limit drawer sag in the display position.
Claim 14
Dependent Claim
22 words
A cabinet according to claim 8 wherein said end guide is V-shaped and engages said pivot pins to support said drawer thereon.
