Abstract
Abstract A frame assembly for use in a furniture structure such as an arm chair or coffee table using a plurality of linearly extensible flexible frames supporting a welded wire mesh. The frame elements are designed to resiliently flex to impart resiliency to the mesh support surface. The rearmost frame member is slidingly attached to the supporting furniture such that it may be pulled out in front of the furniture structure. The support frame is dimensioned to accommodate a single reclining person.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
224 words
In furniture structure of the type having a pair of spaced vertically extending side members, the improvement in combination therewith comprising: a plurality of linearly extensible generally rectangular frame member means slidingly joined to each other so that in a closed position the frame members may lie in overlying relationship within the furniture structure and in an opened position the frame members are substantially coplanar to form a generally horizontal reclining surface outside of the furniture structure, each of said frame member means comprising a generally rectangular frame and a plurality of substantially non-stretchable wires attached to their ends to spaced locations on the frame to form a supporting mesh; leg means for supporting each of said frame members from the floor; and means for slidably attaching said frame between the side members of the furniture structure such that when said frame is pulled out to the opened position, the rearmost one of said frame members will be positioned such that the reclining surface does not extend between the side members, said rearmost frame member being slidably attached to the inside surfaces of said side members, said attaching means including an elongated horizontally extending slot provided on the inside surface of each of said side members and a pin extending outwardly from each side of the rearmost frame member slidingly cooperating with said slot.
