(Cl. 155l94) 10 Claims. 1
The present invention relates to articles of furniture, and more particularly to chairs or the like.
An object of the present invention is to provide a chair or the like, which may be readily assembled.
Another object of the present invention is to provide a chair or the like wherein a shell-like body containing the back-rest of the chair is free from compound curves.
A further object of the invention is to provide a chair or the like which may be readily upholstered without the use of gussets.
A further object of the present invention is to improve on the construction of chairs or the like as now ordinarily made.
With the above and other objects of the invention in view, the invention consists in the novel construction, arrangement and combination of various elements and parts as described hereinafter and set forth in the claims hereof, certain embodiments of the same being described in the specification and being illustrated in the accompanying drawings forming part of this specification, wherein:

Fig. 9 is a rear perspective view of a shell-like body similar to that shown in Fig. 7, which, however, is provided with upholstery,
Fig. 10 is a rear perspective View similar to that shown in Fig. 6 wherein, however, the chair is upholstered, and
Fig. 11 is a sectional view taken on line I l-ll of Fig. 10.
Referring now to Figs. 1, 2, and 4, 20 generally indicates a seat carried by a support generally indicated by 22. The support -22 comprises two side frames 24, 26 of tubular material or the like connected with each other by cross-bars 28. The seat 20 is attached to said support 22 by means of screws or the like passing through bores 30 of the side frames 24 and 25.
Furthermore, a shell-like body generally indicated by 32 is connected to the seat by said screws passing through said bores 30 of the support 22. Said shell-like body 32 comprises a back-rest 3i, two arm rests 36 and 88 and the embracing portions 40, I2 embracing the seat 20 and extending underneath thereof. The shelllike body 32 is provided with an aperture 44 in its center portion. The rear portion of the seat 20 passes through and projects from said center aperture 44 of the shell-like body 32. The shelllike body 32 is of substantially uniform thickness throughout.
Furthermore, according to the embodiment shown in the drawings, the shell-like body 32 is free from compoundly curved surfaces. Insofar as said shell-like body includes curved surfaces, they present unidimenslonal curves. In other words, all areas of the shell-like body, whether they are curved or straight, are traced by straight line generatrices G being at a right angle to the edge of the aperture 44.
The shell-like body 32 of the chair shown in Figs. 1 and 4 may be made from band-like blanks 32a and 32b of sheet material as illustrated by Fig. 3. The sheet material may consist of a plastic or plywood or metal or any other bendable material. The blanks 32a and 321) are bent in a suitable form into the desired shape of the shell-like body 32. Upon suitable shaping of the blanks 32a and 32b the edges 46a and 481) as well as the edges 48a and 48b contact each other, the areas 340. and 84b form the back-rest, the areas 38a and 361) form the arm rests and the areas 42a and 40b form the embracing portions of the shell-like body 32. In the finished product, the contacting edges 46a and 45!) as well as 4811 and 48b of the blanks 32a and 32b are connected with each other at the seams 46 and 40 respectively. Said connections may be obtained by mechanical means, such as screws, or by the use of an adhesive, such as glue, or by a'fusing process in case a thermoplastic material is used, or .by any other suitable means.
Instead of bending the blanks 32a and 32b by means of a form into the desired shape, the various areas of said blanks could also be bent into the desired shape, one after the other, by suitable means, for example by bending same over a mandrel.
Furthermore, the shell-like body 32 of a chair according to the invention could also be made by placing plastic material into a form or mold of suitable shape and shaping said plastic material therein. In such a case, an integral shell-like body would be obtained.
Moreover, if the shell-like body 32 is made by the use of band-like blanks. the blanks may be made of such a shape that in the finished product the blanks are connected with each other only at the seam 46 and that there is a space between the edges 48a and 48b of the embracing portions 42 and 40 of the finished shell-like body 32 extending underneath the seat to a certain extent.
As mentioned above, the shell-like body 32 may be attached to the seat by screws attaching also the support 20 to the seat. If desired, however, the shell-like body 32 and the seat 20 may be connected with each other in any other suitable way. for example by the use of separate screws or by the use of an adhesive.
Moreover, the seat 20 could be carried by four separate legs of any suitable shape and design instead of by a support 22 as shown in Figs. 1, 2 and 4.
According to the embodiment of a chair shown in Figs. -7, the chair comprises again a seat I carried by a support I22. A shell-like body I32 is connected to the seat I20 in any suitable manner, for example by an adhesive or by screws (not shown).
The shell-like body I32 comprises a back-rest I34 and embracing portions I40, I42 which may be joined with each other at the seam I48. Said embracing portions I40, I42 of the shell-like body I32 embrace the seat I20 and extend underneath thereof. The shell-like body I32 may be connected to the seat I 20 in any suitable manner, for example by screws (not shown) passing through bores (not shown) arranged in the embracing portions I40, I42. In the embodiment shown in Figs. 5 and 6, the rear portion of the seat I20 passes through and projects from the center aper ture I44 of the shell-like body I34.
The shell-like body I32 having substantially uniform thickness throughout is free from compoundly curved surfaces, its curved surfaces presenting unidimensional curves. Said body has no arm-rests.
As shown in Figs. 5-7, the shell-like body I32 is provided with dents I50 bulging outwardly. This provides more room for the occupant of the chair between the portions I52 and I54 of the shell-like body I32 and reinforces the latter.
The shell-like body I32 may be made from a blank I32a of bendable sheet material. Upon bending of said blank I32a in a form, the edges I4Ba and M8?) thereof will contact each other, the area I34a will form the back-rest I34 and the areas MM and WM will form the embracing portions I40, I42 of the shell-like body I32.
Of course, the shell-like body I32 may also be shaped in such a way that there remains a space between the embracing portions I40 and I42, so that the latter do not cover the entire width of the lower surface of the seat I20.
The shell-like body I32 may also be made according to any other suitable method, for example according to methods described above in connection with the shell-like body 32 of the chair shown in Figs. 1 and 4.
According to the embodiment shown in Figs. 5-7 the surface of the various areas of the shelllike body I32 are traced by straight-line generatrices and, consequently, the shell-like body I32 is free from compoundly curved surfaces. This feature facilitates to a great extent the upholstering of a chair according to the invention, which can be done without the use of gussets.
According to the embodiments shown in Figs. 9-11 the covering material of the upholstery, for example a fabric I56 is applied to the shell-like body I32 in the shape of a slip-cover. Said slip cover envelopes the shell-like body I32 and a layer of foam rubber I58 or other suitable elastic material cemented to the inner surface of the body I32. The slip cover may be closed by slide fasteners I60, I62 and I64. Of course, the slide fasteners may be arranged in a different manner or a different type of closing means may be used for holding the slip-cover I50 in place.
As best shown in Fig, 11, the seat I20 is, likewise, upholstered. The shell-like body I32 is connected to the seat by screws I66 passing through bores of the support I22, thus connecting also said support to the seat.
Of course, the chair shown in Figs. 5-7 and 10 may also be provided with separate legs instead of a support carrying the seat-back-rest assembly.
Moreover, the dents I50 shown in Figs. 5-7 may be omitted, if desired.
Furthermore, if desired, the chair shown in Figs, 1 and 4 may also be provided with upholstery and, as the shell-like body 32 of said chair is free from compound curves, the covering material of such upholstery may also be applied to said chair in the form of a slip-cover.
