Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
222 words
A clip and spring assembly quickly securable to a slotted flat web of a furniture frame, said assembly comprising an elongated zig-zag spring having a transversely extending end bar at each end thereof, and a clip permanently secured to each end bar, each clip being imperforate and of sheet material of uniform width throughout and having means at one end thereof for securing the clip to the spring, said means being in the form of a substantially cylindrical loop embracing and substantially closed upon the major part of the circumference of said end bar and permitting oscillation of said bar within the loop when the spring is loaded and unloaded, said clip having a flat intermediate horizontal base extending outwardly from the lowermost part of said loop and adapted to have the under surface thereof rest on thE upper flat surface of said slotted frame web, said clip terminating in an L-shaped portion extending downwardly from said base and having a flat terminal leg substantially parallel to and in downward spaced relation to said base and adapted to become arranged below the under face of said slotted frame web, the other leg of said L-shaped portion joining said terminal leg to said base and being dimensioned to arrange the loop and the base on the upper face of said slotted frame web.
Claim 2
Dependent Claim
222 words
A clip and spring assembly quickly securable to a slotted flat web of a furniture frame, said assembly comprising an elongated zig-zag spring having a transversely extending end bar at each end thereof, and a clip permanently secured to each end bar, each clip being imperforate and of sheet material of uniform width throughout and having means at one end thereof for securing the clip to the spring, said means being in the form of a substantially cylindrical loop embracing and substantially closed upon the major part of the circumference of said end bar and permitting oscillation of said bar within the loop when the spring is loaded and unloaded, said clip having a flat intermediate horizontal base extending outwardly from the lowermost part of said loop and adapted to have the under surface thereof rest on thE upper flat surface of said slotted frame web, said clip terminating in an L-shaped portion extending downwardly from said base and having a flat terminal leg substantially parallel to and in downward spaced relation to said base and adapted to become arranged below the under face of said slotted frame web, the other leg of said L-shaped portion joining said terminal leg to said base and being dimensioned to arrange the loop and the base on the upper face of said slotted frame web.
Claim 3
Dependent Claim
52 words
The clip and spring assembly of claim 1, the loop terminating in a flat edge portion extending outwardly therefrom and adapted to receive loop-closing pressure when the loop is to be closed around the end bar of the spring, said flat edge portion terminating adjacent said other leg of the L-shaped portion.
Claim 4
Dependent Claim
89 words
In a furniture spring installation, the clip and spring assembly of claim 2 and a pair of furniture frame elements each having a flat relatively thin sheet metal web provided with a relatively narrow elongated slot therethrough of approximately the width of said clips in length and of approximately the thickness of the material of said clips in width, the terminal leg of each clip being underneath the under face of the web of said frame element and in outward spaced relation to the end bar of the spring.
Claim 5
Dependent Claim
86 words
The furniture spring installation of claim 3, the loop and the base of each clip resting on and holding the end bar above the upper surface of the frame web and transmitting thereto loads put upon the spring, the loop terminating in a flat edge portion extending outwardly and angularly therefrom and adapted to receive loop-closing pressure when the loop is to be closed around said end bar, said flat end portion terminating adjacent the slot and being substantially parallel to the base of the clip.
Claim 6
Dependent Claim
42 words
The furniture spring installation of claim 3, the inner part of the base of the clip projecting inwardly beyond the inner edge of the frame web and the outer portion only of said base resting on the upper surface of said web.
