Abstract
Abstract A self-clamping wire rack is provided for magazines, cards, napkins, letters, and the like; the rack being formed in its basic configuration of a first wire rod which is bent to constitute the rear side of the rack and also to constitute a pair of rearwardly extending legs; and of a second wire rod bent to constitute the front side of the rack and also constitute a pair of forwardly extending legs; the two components of the rack being hinged to one another in a manner such that when the assembly is placed on a horizontal surface, the front and rear sides are turned angularly towards one another to exert a clamping force on the magazines, cards, or other articles supported on the rack between the front and rear sides of the rack, so as to maintain such articles in the rack.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
129 words
A wire rack for supporting magazines, and the like comprising: a first wire-formed frame having an essentially U-shaped configuration and having lower article-carrying end portions extending forwardly of the plane of the frame and having a further lower end portion extending rearwardly of the plane of the frame to constitute rear legs for the rack; and a second wire-formed frame having an essentially U-shaped configuration hinged to the first frame in facing relationship therewith, said second wire-formed frame having lower end portions extending forwardly of the plane of the second frame to constitute front legs for the rack, whereby articles supported on the article-carrying portions of the first frame cause the first and second frames to turn angularly toward one another to exert a clamping action on such articles.
Claim 2
Dependent Claim
129 words
A wire rack for supporting magazines, and the like comprising: a first wire-formed frame having an essentially U-shaped configuration and having lower article-carrying end portions extending forwardly of the plane of the frame and having a further lower end portion extending rearwardly of the plane of the frame to constitute rear legs for the rack; and a second wire-formed frame having an essentially U-shaped configuration hinged to the first frame in facing relationship therewith, said second wire-formed frame having lower end portions extending forwardly of the plane of the second frame to constitute front legs for the rack, whereby articles supported on the article-carrying portions of the first frame cause the first and second frames to turn angularly toward one another to exert a clamping action on such articles.
Claim 3
Dependent Claim
40 words
The wire rack defined in claim 1, in which said rear legs have downwardly extending feet portions formed at the extremities thereof, and in which said forward said front legs also have downwardly extending feet portions at the extremities thereof.
Claim 4
Dependent Claim
46 words
The wire rack defined in claim 1, in which the forwardly extending and rearwardly extending lower end portions of the first frame form pivot eyes which receive the lower end portions of the second frame to provide a hinge coupling between the first and second frames.
Claim 5
Dependent Claim
42 words
The wire rack defined in claim 1, in which said first wire-formed frame and said second wire-formed frame have similar shapes and in which said second frame also includes lower article-carrying end portions extending rearwardly from the plane of the second frame.
Claim 6
Dependent Claim
82 words
The wire rack defined in claim 4, in which the forwardly extending end portions and the rearwardly extending end portions of the first frame form pivot eyes; and in which the rearwardlyextending portions and forwardly extending portions of the second frame also form pivot eyes, with the aforesaid pivot eyes all being axially aligned with one another; and which includes a rod extending through said pivot eyes to couple the first frame and second frame to one another in a hinged relationship.
Claim 7
Dependent Claim
118 words
The wire rack defined in claim 5, and which includes a third U-shaped wire-formed frame secured to said first frame, and including lower article carrying end portions extending forwardly from the plane of said second frame, with the extremities thereof looped around said rod; and a fourth U-shaped wire-formed frame secured to said second frame and having lower article-carrying end portions extending rearwardly from the plane of said fourth frame and having extremities looped around said rod, the first and third frames being in essentially co-planar relationship, and the second and fourth frames being in essentially co-planar relationship, and the third and fourth frames extending upwardly beyond the first and second frames to constitute handles for the rack.
Claim 8
Dependent Claim
54 words
The rack defined in claim 6, in which the extremities of the lower end portions of the third frame extend under the lower end portions of the fourth frame to provide a stop means for preventing angular opening movement of the rack beyond a predetermined angular relationship between the first and second frames thereof.
