Abstract
A mattress supporting foundation unit which is constructed to offer very firm support to a mattress, and which includes a base frame, a horizontal wire mesh spaced above the frame, and support wires for connecting the mesh to and supporting it from and above the frame, with these support wires having portions forming legs which extend upwardly from the base to the mesh and are substantially straight for their entire length between the base and mesh to give the desired rigidity to the overall structure. The support wires desirably also have connector portions which extend laterally between successive legs and are attached to the base and mesh.
Claims15
A foundation unit for supporting a mattress, comprising:
- an essentially horizontal base frame having side rails extending along opposite sides thereof longitudinally of the frame, and having cross members extending transversely between said side rails at head and foot ends thereof and therebetween;
- an essentially horizontal upper structure spaced above said frame and including a horizontal mesh of intersecting and interconnected longitudinal and transverse wires, and a peripheral wire of greater strength extending about and connected to the periphery of said mesh;
- a plurality of supporting units connecting said upper structure to and supporting it from said frame and each formed of a continuous strip of wire bent to form a series of legs which extend approximately directly vertically from the frame to said upper structure at different locations and are connected at lower ends to the frame and at upper ends to said upper structure, and which are substantially straight for the entire distance from the frame to the upper structure, each of said continuous strips of wire forming a plurality of essentially horizontal connector portions each extending laterally between and integrally interconnecting corresponding ends of two successive legs of the same strip;
- certain of said continuous strips extending along said oppposte side rails and having alternate connector portions of an individual strip attached to a side rail and said peripheral wire of said upper structure respectively;
- others of said continuous strips of wire extending transversely along said cross members at the head and foot ends respectively of the foundation unit and each having alternate connector portions attached to a cross member and said peripheral wire respectively;
- additional ones of said continuous strips of wire being disposed along cross members at locations longitudinally intermediate the head and foot ends of said frame and each having alternate connector portions attached to a cross member and said mesh respectively.
A firm foundation unit for supporting a mattress, comprising:
- an essentially horizontal and essentially rectangular base frame having side rails extending along opposite sides thereof longitudinally of the frame, and having cross members extending transversely between said side rails;
- an essentially horizontal upper structure spaced above said frame and including a horizontal mesh of intersecting wires, and a peripheral wire of greater strength connected to the periphery of said mesh;
- a plurality of supporting units connecting said upper structure to and supporting it from said frame and each formed of a continuous strip of wire bent to form two spaced substantially parallel legs which extend upwardly approximately directly vertically from the frame to said upper structure and are connected at lower ends to the frame and at upper ends to said upper structure, and which are substantially straight for substantially the entire distance from the frame to the upper structure so that most of the weight of a mattress and a person on the foundation unit is taken by the wire legs in compression;
- each of said continuous strips of wire forming a horizontal connector portion interconnecting corresponding ends of said two spaced approximately vertical legs of the same strip of wire.
