FURNITURE STRUCTURE
FIELD OF THE INVENTION
This invention is concerned with a furniture structure suitable for chairs, benches and the like which is assembled without the use of tools, fasteners, or welding. It also relates to a method for making such furniture.
BACKGROUND OF THE INVENTION
Already known in the prior art, there are the so-called take-apart furniture structures which are assembled without the need of tools or fasteners.
Examples of such prior art are given in US 5,387,027 or US 5,605,378. The front page of these documents is enclosed herewith. As can be appreciated, these structures which are designed to be easily and quickly dissassembled for storage and shipment have the following drawbacks:
there are not very strong indeed and with times, more particularly under the effect of continuous assembling and disassembling, the interlocking joints wear out and loosen.
SUMMARY OF THE INVENTION
The aim of the present invention is not to obtain a take apart furniture which could be easily disassembled for storage or shipment. It is rather to obtain a very strong and solid piece of furniture as compared to the ones assembled with screws and/or welding. It is also to obtain a piece of furniture which is believed to be more esthetical and less likely to rust because of the absence of screws and/or welded joints.
According to these objects, our client has developed a furniture structure which essentially comprises a plurality of framing members made of a rigid material which can sustain plastic deformation. The framing members are assembled by press-fit so to form the furniture structure. Once assembled, the structure cannot be disassembled easily. The assembling which does not require any screws andlor welding is performed with a specially design press-fit apparatus.
DESCRIPTION OF A PREFERRED EMBODIMENT
Figures 1 to 3 illustrate a chair embodying features of the present invention. Figure 1 is a perspective view of the chair. Figure 2 is an exploded view of region 1 encircled in figure 1 and figure 3 is a bottom view of one of the back legs of the chair.
As shown in figure 1, the chair (10) according to the invention comprises two side framing structures (12,14). Each of which preferably consists of a bent aluminum extrusion defining a front leg (16), an arm rest (18) and a back leg (20) of the chair. The chair further comprises a front cross rail (22) interconnecting the front leg (16) of each side framing structure (12,14), a back cross rail (24) interconnecting the back leg (20) of each side framing member (12,14) at an upper part thereof and a spindle (26) interconnecting the back legs (20) at a lower part thereof.
Each of the front cross rail (22), the back cross rail (20) and the spindle (26) is made of a rigid material that can sustain plastic deformation and has both their ends press fitted in a hole (27) provided in the respective side framing member (12 or 14) and best seen in figure 2.
Referring to figure 2, one end (28) of the front cross rail (22) in its original state, that is to say before the assembling by press-fit, is illustrated. In this case, the end (28) preferably consists of two pegs (28a and 28b) projecting from a main planar portion (30) of the front cross rail (22). Each peg (28a, 28b) has an original diameter before press-fit that is greater than the diameter of its corresponding hole (27) provided in the side framing member (12). During the press fit which is pertormed with a specifically designed apparatus, each peg (28a or 28b) is deformed to fit into the hole (27). Once inserted, the peg is firmly held in the hole and cannot be removed therefrom, and that, without requiring screws, glue or welding.
Referring to figure 3, the extrusion forming a side framing member (12 or 14) may comprise a transversal inside wall (30) provided with apertures (32) each in line with a corresponding hole (27) provided on an inner wall of the side framing member (12). Once the spindle (26) is inserted in the side framing member (14), a screw (34) may be installed across the spindle as shown in figure 3, to make sure the spindle will not come out with time.
Although preferred embodiments of the present invention have been described in detail herein and illustrated in the accompanying drawings, it is to be understood that the invention is not limited to these precise embodiments and that various changes and modifications may be effected therein without departing from the scope or spirit of the present invention.
For example the furniture structure could be a bench, the seat of a swing, etc.
