Description

March 21, 1961 A. MAUSER CHAIR FRAME STRUCTURE Filed Nov. 22, 1957 Alfons Mauser, Koln-Ehrenfeld, Germany, assignor to Mauser Kommandit-Gesellschaft, Koln-Ehrenfeld, Ger- The present invention relates to devices for connecting and supporting chair frame portions.
When constructing chair frames, especially those made of steel or other suitable metal, the basic shape of the chair is determined chiefly by the particular manner in which the individual parts of the chair frames are joined together.
Prior to the present invention, it was considered an absolute requirement that two or more parts had to be formed from a continuously bent or combined shaped strip, which for example formed the seat and back frames, with a base support frame attached thereto, or the shaped strip formed the seat and support frames and the back frame was secured thereto. Wherever the shape of the finished chair varied, special finishing steps were necessary and this considerably increased the production cost of the chair frames therefor. This is especially true of the numerous points which had to be joined together by welding, soldering, or the like.
The primary object of the present invention is to provide means obviating the disadvantages of the prior art by the provision of means operable to unite or combine all portions of the chair frame.
Another object of the present invention is the provision of means conducive to a very efiicacious chair frame construction wherein the outer shaping of the chair is not dependent upon the frame thereof so that complete freedom is provided to the designer and manufacturer.
It is still another object of the present invention to provide means necessitating only a single base frame device which can be utilized in the assembly of many differently shaped chair models and like furniture.
A further object of the present invention is to provide means contributing to a frame structure of the aforesaid type which permits the use of one, two, three or four supporting legs for the chair, as desired.
A further object of the present invention is to provide means ensuring an improved chair frame structure which readily and variedly permits the assembly and joining of the individual parts of which the chair may consist, under a protective covering, so that no additional attaching or securing means are required in most cases, so that any welding or soldering connections which greatly add to the expense of the chair, can be obviated.
A still further object of the present invention is to provide means avoiding the need for any special surface treatment of the chair frame parts as the same will be covered by the seat and back of the chair and remain completely hidden from view.
Other, further and additional advantages of the present invention will be readily apparent from a reading of the following specification and claims taken in connection with the appended drawings which illustrate some Patented Mar. 21, 1961 "ice of the best modes presently contemplated of carrying out the invention.
In the drawings:
The figure is a perspective view of a chair pursuant to the present invention.
Referring now to the drawing in detail, there is shown an embodiment of the present invention. As shown, provision is made for a chair 50a having a back 14 provided with a frame 13 in the form of a rod bent to an arcuate shape, which forms the peripheral boundary thereof, and a seat 17 provided .with a frame 16 in the form of a rod bent to an arcuate shape, which forms the peripheral boundary thereof. The chair support and interconnecting device 11 is provided with the laterally related distributor supports Ila-11a which are interconnected by the transverse sttut or brace 10a. The fingers l2 and 15 forming supports l1a11a are arcuate in configuration and conform to the curves of the back frame 13 and seat frame 16.
Each support 11a has an upwardly extending finger 12, which mounts the adjacent end of the hollow back frame 13, a forwardly projecting finger 15, which mounts the adjacent end of the hollow seat frame 16, and a depending finger 9a which receives, or is received, as the case may be, by the adjacent rear leg 4a of the support frame 4 as previously described.
The present invention is not limited to use with chair frames formed of steel or metal but can also be utilized for chair frames formed of other material, such as, for example, wood.
Various changes and modifications may be made without departing from the spirit and scope of the present invention and it is intended that such obvious changes and modifications be embraced by the annexed claims.
Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent, is:
A chair frame comprising a pair of laterally spaced support portions each having three fingers, one finger of each portion extending rearwardly and upwardly therefrom, a second finger of each portion extending forwardly therefrom and a third finger of each portion depending therefrom, said spaced portions being interconnected by an arcuate downwardly curved yoke defining the boundary of the seat and back of the chair, said upwardly extending fingers being arcuate in shape and forming part of the periphery of the back of the chair, an arcuate peripheral chair back frame portion directly engaged with said upwardly extending fingers and forming in conjunction therewith and with said yoke a substantially oval shaped chair back frame, said forwardly extending fingers being arcuate in shape and forming part of the periphery of the seat of the chair, an arcuate peripheral chair seat portion directly engaged with said forwardly extending fingers, and a base support secured to said fingers depending from said arcuate yoke.
