FRAME FOR CHAIRS, TABLES AND THE LIKE Filed Dec. 30, 1932 iNVENTOR ATTORNE bent metal strips.
Patented July 2, 1935 UNITED STATES PATENT OFFICE August Niederkroim'l lanover, Germany, assignor to Voss a Sasse, Stulilfabriken,
(Deister) Germany Lauenau Application December 30, 1932, Serial No. 649,669 In Germany December 31, 1931 2 Claims The present invention relates to a frame for chairs, tables or the like. 1
Such frames are known in which the corners of the frames are provided with Wooden blocks or Special screw connections and metal pins which must be connected with the legs of the frame are also known.
Contrary to all such known kinds of corner connections, the present invention produces a positive stiffening of the whole chair or table frame without the use of any kind of pegs, peg holes, screw connections, metal pins, metal angles, corner blocks and the like. This result is accomplished by securing to each of the inner side surfaces of the rim or border frame two ledges or bars which are separated from each other by intermediate spaces, the ends of these bars pressing strongly against the inner upper side sur-' faces of the legs. A bottom plate which is solidly connected with the lower bars has corner cut outs which solidly surround the edges of the legs and press the legs against the corners of the border frame; By this means, all rails and bar connections below the border frame, or at the lower ends of the legs, where they are often inconvenient, and are objectionable places for the deposition of dust, may be dispensed with.
Furthermore, all parts directly abut with an unweakened cross section squarely against each other without tenons, dowels, screws or the like, so that the many places where breakage may occur, which are produced in known frames by tenons, mortises and the like, are done away with by the object of the invention.
The invention is more particularly described with reference to the accompanying drawing, in which:
Figure l is a vertical section through a frame Figure 2 a corresponding horizontal section, and
Figure 3 an inside perspective view of a corner of the frame.
The chair or table-frame according to the invention consists of the border frame a, the legs 12 standing at the inner angles of the border frame,
the bars 0 and d placed between the legs, which press the legs firmly against the border frame and against one another; and the plate e firmly enclosing the border frame and legs and effectively protecting the. frame against diagonal distortion or warping (see direction of arrows).
By the arrangement of all the connections and stiffening members--bars c and d and plate ein the border frame a, and the avoidance of any tenons and mortises on the legs and points of connection the frame is unbreakable.
Having now particularly described the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. Furniture structure of the class described comprising an outer rectangular frame, a leg mounted in each inside corner of the frame, four upper spreader bars extending along the upper portion of the inner sides of the frame and between the upper ends of the legs, four lower spreader bars spaced below the upper spreader bars and extending along the lower portion of the inner sides of the frame and between lower portions of the legs, said upper and lower spreader bars pressing the legs firmly against the inside corners of the frame, and a bottom plate secured below the lower spreader bars and closing the lower portion of the frame, said bottom plate having its corners cut out to receive and press against'the legs, whereby diagonal distortion or Warping of the frame is prevented.
2. Furniture structure of the class described comprising an outer rectangular frame, a leg mounted in each inside corner of the frame, four upper spreader bars extending along the upper portion of the inner sides of the frame and between the upper ends of the legs, four lower spreader bars spaced below the upper spreader bars and extending along the lower portion of the inner sides of the frame and between lower portions of the legs, said upper and lower spreader bars pressing the legs firmly against the inside corners of the frame.
