Application June 12, 1950, Serial No. 167,625

9 Claims. (Cl. 155-196) .The present invention relates to furniture, such as upholstered chairs, sofas, and the like. Aprincipal object of the invention is to provide suchan article of furniture having separate base, side and back members which can be readily ,asfsembled into a complete article, such as a chair or sofa. Ancillary to the objective just mentioned, it is a purpose of the invention to provide such an article of furniture, having the sides and back connected to the base in such manner that they may be readily detached therefrom, whenever it is desired to break-down the article of furniture. Of course, the provision for detaching and removing parts of the article of furniture permits dismantling and storing of the furniture in confined space, as well as transportation of the furniture without injury and while occupying a minimum amount of space.

Furniture embodying the present invention may be manufactured in parts and initially shipped in this condition and the parts may thereafter be assembled at the retail store or even in the home of the purchaser.

The elements of furniture are equipped with and in a manner which is well known in the art.

In said drawings:

Figure 1 is a perspective view of the chair, looking inwardly of the base member from one front corner toward an opposite rear corner, showing the back member attached to the base and showing one opposite side member about to be secured on the base member.

Figure 2 is a side elevational view of the chair assembly of Figure 1, showing the opposite side member of the chair in place, or mounted on 3 the base member.

Figure 3 is a detail view showing one end of the back member positioned just above the upper end of one of the rear posts of the base member, just before the back member is mounted on the post.

Figure 4 is a partial elevational view of one of the side members of the chair, looking outwardly.

Figure 5 is a partial transverse vertical sectional view through one of the side members taken along the line 5-5 of Figure 2', showing themanner in which the side member is attached to one of the rear posts of the base member and.

the manner in which this side member locks the back member in place on said post.

Figure 5a is a view similar to Figure 5 except that the section is taken through the secur- .ing clasps rather than forwardly thereof.

2 Figured is a partial longitudinal vertical sectional view through one ofthe side members of the chair, showing the operating mechanism for moving the lower horizontal bar carrying the keepers or clasps upwardly to engage the lugs on the posts of the-base member, in order to lock the side member in place on said posts.

Figure 7 is a perspective view from the front, showing the base member with its separate seat platform in place, the side members removed, and with the back member about to be secured on the upper ends of the rearward posts of the base member.

, Referring to Figure 1, the base member B is a suitably formed framework, preferably of metal, and made up of suitable metal plates or. rods secured to one another as by welding. The base member has side plates Ii! and front and rear plates l2, there being outwardly directed. legs 14 at the forward corners to support the frame on the floor. Extending upwardly from the front corners are front posts l6 and I8, secured to the frame in any suitable manner as by welding, and at the rearward corners there are similar posts 20 and 22, the lower ends of these posts constituting vertical legs to support the frame on the floor. The legs I8 and 22 are, respectively, identical in construction with the legs 16 and 20.

The post [8 is provided with an outwardly and downwardly directed clasp lug 24, adjacent to the lower end of said post, and with an upwardly and outwardly directed clasp lug 26 adjacent to the upper end of the post. The post 22 is equipped with a similar lower lug 28, and at its upper end this post is provided with a slot 35 extending transversely therethrough and downwardly into the post from its upper end for a short distance, as shown in Figure 3. This slot is adapted to receive a clasp lug 32 carried by the back member K, Referring again to Figure 3, the lug 32 has a lower fork 34, which serves to support the back member in the slot 30, and an upwardly and outwardly extending fork 36 which serves the same purpose as the lug 25 on the post I8, i. e., to support the side member on the post in a manner hereinafter described. Thus, lug 32 becomes a part of the base when the back is in place.

Referring again to Figure 1, one side member is shown at S. It comprises a Wooden form for the upholstery suitably secured to a substantially rigid metal frame consisting of upper and lower bars 38 and 40, respectively, and vertical end bars 42. The upholstery frame may be of any suitable construction, and is attached to and carries the metal frame just described. The upholstery frame may be made of Wood, and may consist of top, intermediate, and bottom boards 44, and 48, and end boards 52 and 54, all suitably secured to one another as necessary and. to the metal frame referred to by any conentional means. The upper bar .38 of the metal frame is provided with forward and rearward clasps or keepers 56 and 58, these clasps consisting of small plates welded to the inner face of the bar 38 and having downwardly opening slots 60 therein to fit over and latch with the lug 26 on the forward posts of the base member and the lugs 36 :car

over the lugs 26 and 36, with the bar 66 in its lowermost position, and with the slots in the lugs 62 and 64 disposed below the lower lugs 24 and 28 on the posts I6 and 20. Thereafter, a suitable wrench is applied to the nut 84 on the stem 12 and upon properly turning this stem the bar "66 is shifted upwardly until the slots in the its bifurcated ends I0 which surround the vertical bars 42 of the metal frame I movement of the lower metal bar 66 with're'spect to the upper metalbar 38 is accomplished by a vertical stem 12 which has a bearing as at 14 The adjustable (see Fig. 6) in the bar 40 and in. the "wooden.. board 48, and which has a heavy threaded por-" tion I6 which engages interior threads 18 in a bushing block 80 carried by the bar 66, it being understood that the latter may be of channel shape substantially throughout its entire length. with the threaded bushing 80 secured within the channel as bywelding.

The upper end of the stem 12 is mounted for turning movement in a bushing 82 likewise secured in the upper metal fixed channel bar 38,. and the stem has a head 84 positioned in. a well" 86 in the intermediate board 46, whereby suitable tools such as a wrench may be applied to turn the stem I2, and thus raise and lower the metal bar 66.

An adjustable collar 88 may be secured in proper position on the stem I2, against the" lower surface of the bushing 82 to retain the .stem I2. against vertical movement, whereby when the stem I2 is turned, the non-rising stem action of the threads 16 and 18 will cause the,

bar 66 .to move upwardly and downwardly.

As is apparent from the above description, the clasps 62 and 64 are carried on the moving bar 66, and when the stem I2 is turned in the proper direction, these clasps are moved upwardly to engage beneath and around downwardly di-" rected lugs 24 and 28. l

. The back member K may comprise a horizontal wooden board 96, side wooden frame members 92 and a top cross wooden member 94, and the members 92 are braced in their attachment to the member 90 by unitary metal brackets which carry the clasps 32 with their upwardly directed lugs 36. As shown in Figure 1, these brackets I serting the forks 34 of the clasps 32 downwardly into the top slots 30- in the posts. When this is done, the posts 20 and 22 then have upwardly extending securing lugs 36 substantially-the same as the similar lugs 26' on the forward legs I6 and I8.

Thereafter, the side members of the chair are assembled as will be apparent in Figure 1, by positioning the slots 60 of the. clasps56 sand 58 clasps 62 and 64 engage around and lock against the lower surfaces of the lugs 24 and 28. The stem is turned until the clasps are tightly locked with the lugs. Of course, the same operation isv carried out for the opposite side member of the chair.

After this operation, the side members are not only securely attached to and locked onto the posts of the base member, but also, the back member is securely locked in place in the slots on the upper ends of the rearward posts 20 and 22, and the chair is in a rigid condition suitable for use, just as if the side and back members were integrally secured to the base member,

.as by such conventional means as nailing or screwing the parts together, as in conventional constructions.

While only the framework of the chair is shown in the drawings, it will be understood that the side, base and back members may be covered with suitable upholstering, as is well known in-the art, to provide a chair of the upholstered or overstuffed type. Of course, the invention is applicable to other than the upholstered type of chair, and can be used in assembling openwork chairs, made of wood or metal or other suitable materials, and the application of the invention is not confined to any particular form of chair.

Referring to Figures 2 and 7, a bottom support may be provided for the seat cushions of the chair, consisting of a framework which is placed on and is supported by the front and rear rods I2 of the base member. This bottom support may comprise an upwardly extending front cross-piece I00, a rear cross-piece, and longitudinally extending bottom supporting slats I04. The bottom support may also have vertical and angularly disposed supporting members I06 and I09-and a top cross-piece I08 attached thereto providing a suitable frame for carrying the usual upholstery necessary to complete the back of the chair. The

bottom support may also have an upwardly extending cross slat I01, so that the seat cushion or cushions may be held on the slats I04 between the cross-pieces I00 and I01. In the design shown, the bottom support is arranged to receive seat cushions of suitable thickness, which would be positioned as described betweengthe side members S of the chair, and the seat cushions may be of a thickness to extend up substantially to the bottom board 90 of the back member K.

. The back member K will be upholstered above the board 90 to provide a'cushioned back extending upwardly and rearwardly from the seat cushions or similar upholstery on the bottom support; The side members will be covered with suitable upholstering, leaving the clasp members exposed,

so that the upholstered parts may be assembled and locked together in the manner previously sofas and thelike.
