This invention relates to furniture, especially to furniture made from a plurality of sections that are removably secured together and that have light weight metal frames.

While the process of manufacture of most articles has changed materially in the past several decades, as have the articles themselves, still some articles, particularly furniture, are being manufactured today as they were many years ago. Household furniturehas long presented a 4 Claims. (01. 155-179) problem to all housekeepers due to the difiiculty in moving the heavy, cumbersome articles around for cleaning, or other purposes. Also, in moving furniture long distances, the freight charges for the bulky objects are often so large as to make 1 shipment of the furniture to a new home site inexpedient. Then, too, a piece of furniture may be seen in a store and be desired but different style arms or back may be preferred, which styles are not available.

The general object of this invention is to avoid metal springs to a metal frame in a permanent manner which prevents metal to metal contact.

The foregoing, and other objects of the invention which will be realized as the description proceeds, are achieved by the provision of an alumi num sheet metal frame which is formed of a base,

a back, and end sections, which section are provided with means for securin them together securely and rigidly but in a quickly and easily detachable manner. Zig-zag springs are provided as the resilient supports for both the base and back sections and in the furniture base one endof each of the springs is brought back in under the load supporting portion of the seat to reenforce it, and special locking clips are provided to secure the springs to the metal frames, which clips may have fabric bushings therein to insulate the movable springs from their positioning means, while suitable cover and cushioning means are secured over the springs to complete the seat.

Attention now is directed to the accompanying drawings, wherein:

Fig. 1 is a perspective view of a davenport embodying the principles of our invention;

Fig. 2 is an exploded view of the sections of the davenport of Fig. 1; i

Fig. 3 is a fragmentary section taken on line III-III of Fig. 4; Fig.4 is a vertical section through the center of the davenport of Fig. 1';

Fig. 5 is a fragmentary elevation of the means of anchoring one spring end to a bowed spring section;

Fig. 6 is an enlarged detail section taken through the spring securing means of the invenion;

Fig. 7 isa fragmentary plan view showing the special support for the end springs of the davenport base;

. Fi 8 is a section taken on line VIII-VIII of Fig. 7.; r

, ,Fig. 9 is a detailed vertical section taken through a modified type of means for securing sections of furniture together;

Fig. 10 is a fragmentary exploded plan view of a clip used to secure sections of furniture together;

Fig. 11 is a fragmentary section through one typle of fabric securing means of the invention; an Fig. 12 is in larger scale a side view of the seat spring by itself.

' For illustrative purposes, the invention is shown as applied to a davenport, generally indicated at Ill, and, specifically, it is shown as comprising a back section H, end sections 12, a base section I3, and cushions M. The end sections l2 carry inwardly extending threaded pins or bolts l5 the back pair of which is positioned for engagement with holes H5 in the frame of the back ll. Wing nuts I! are engaged with the bolts [5 for securing the ends l2 to the back H, which bolts also secure the base section to the assembly through rearwardly directed arms I8, having holes I 9 therein, through which the lower bolt on each side of the back of the davenport end extends. Likewise holes 2l in the front portion of the base section l3 receive the forwardly positioned bolts [8a on the end sections so that the sections can be secured together by wing nuts 22. It will be realized that the abutting surfaces of the davenport sections are of complemental shape so that they are easily secured together tightly and form a rigid structure. Foot support members 23 may be provided on the base section l3 or back section II, or both, as desired.

Fig. 4 brings out the detailed construction of the davenport in more clearly and a feature of the invention is the use of light weight sheet metal, such as aluminum, in forming the davenport frame. In the back section I i, a triangular top member 24 extends between and is suitably secured to channel shaped end members 25 which also are connected by a substantially box-type base support 30 at the bottom of the back section. Likewise, the frame of the base section I3 is made in the shape of an open center rectangle which includes suitably constructed box-like front and rear members 26 and 27, respectively, which are connected by channel shaped arms 28 secured thereto in a conventional manner, as by rivets. The supports 23 may be secured to the arms 23 which may extend rearwardly of the base section to form the arm l8 for anchoring the back of the base to the 'davenport. In the end sections 12, the frame may comprise front and rear channel members, 29 that have the desired contoured upper surfaces and-asheet member 3| may be securedover such upper surfaces and extend down the end sections a desired distance, such as to a point below the upper surface of the cushions l4. A channel or other ,l'eenforcin member (not shown) may be secured between the channels 29 adjacent their lower ends to complete the frames of the end sections. To contribute to the lightness of the davenport In, discs, or other shapes (not shown) are stamped out of the sheet metal used in forming the frame in as great an area thereof as possible without undesirably reducing the'strength of the frame or impairing an outside surface thereof. The support 30, and members 28 and 21 are especially suited for such metal removal and in fact such apertures in the frame are desirable in that they permit ready access to the interior of such members to secure them in place, or possibly secure their components together, orto secure covering material thereto. If desired, additional reenforcing or supporting members may be associated with the davenport frame in any conventional manner.

In the spring means used in the invention, further weight is removed with relation to previous types of seat constructions and a desirable cushion support is provided by the use of a plurality of zig-zag spring wires 32 that are secured to and extend in parallel relation between the members 26 and 27 of the seat base, and between the top member 24 and base support 30 of the seat back. As shown in Fig. 4, the springs 32 extend rearwardly and upwardly from the front member 25, then are doubled back on themselves to extend upwardly and outwardly of the seat. This shape of the springs forms a good load receiving surface at the front of the base section. The springs 32 in the base, after being doubled back on themselves to extend to the front upper edge of the base, then are again doubled back to extend arcuately to the rear of the member 21 and are secured thereto, as explained hereinafter. In order to provide a better support, the springs 4 32 do not terminate at the member 21 but continue in a forward direction and their ends are secured to the arcuately extending center spring portions by clips 33, or other suitable means. Note that the spring ends extend substantially perpendicularly to the center spring ortions adjacent the rear and in the primary load carrying section thereof.

Fig. 6 is a detail section through the spring anchoring means of the invention and it shows the front member 26 which has sections removed from it at both of the upper corners formed therein to form holes 34 through which a metal bar or strip 35 may be positioned on the lower surface of the upper section of the member 26, and which extends from both sides thereof. It has been found that a very effective mounting of the springs 32 is secured by clamping the ends of the strap 35 down onto and partly around the spring wire 32 on opposite loop sections thereof. As the spring wires 32 may have slight relative movement with relation to the member 26, or straps 35, fabric or other suitable insulating means 36 may be positioned around the spring wires 32 before securing the-m in place to prevent any noise occurring on spring fiexure.

In the back section II, the springs 32 are secured to the member 24 and support 30 in the same manner as illustrated in Fig, 6, only in this instance the springs end on both the member 24 and support 30 and form a bowed support therebetween, as shown in Fig. 4.

Fig. 4 indicates that the cushions H are formed of cellular rubber but it will be realized that other suitable cushioning material may be substituted therefor. However, it has been found that the zig-zag springs in combination with the cellular rubber, provide a very comfortable seat with good load support characteristics. In some instances, it may be desirable to secure adjacent springs 32 together by suitable connectors (not shown) such as coil springs to prevent side sway of the springs. The; springs 32 are prepared for load support by placing thin pads 31 of sisal, rubber bonded hair or other cushioning materialthereon. Sheet means, such as burlap or canvas sheets 33, may be carried by the springs 32 to receive the pads 31. Cover means 39 made from a suitable material, usually fabric, then are positioned over each set of the springs 32 and secured to the furniture frame by snaps, clips, or other desired means. An illustrative snap member 40 is shown on the lower edge of the cover 39 and it engages with a complementary snap 40a on the member 26 to secure the cover to the frame. Any suitable padding 50 may be positioned around the frame of the end section l2 and be secured thereto by a cover 500. positioned thereover and suitably engaged with the frame by any desired means, such as snaps similar to the snaps 40 and 40a. It will be realized that in securing cushion material, or covers to the furniture sections, the bolts l5 and Illa and means for engaging with them will in all events be left accessible so that the sections can still be readily secured together.

In some instances, it is necessary to provide additional support for the springs at the seat ends and this result may be achieved by making such springs of stiffer wire than the remainder of the springs. Or, as best shown in'Fig. '7, a special spring, such as a zig-zag spring 4| may be positioned under the end spring 32. The support spring 4! then is secured to the spring 32 by clips 43 and to the arm 28 by a strap 45, similar to the strap 35, which extends around the upper section of the channel arm 28 and is clamped at its ends to the spring 4 I. i

Fig. 9 shows a modified type of connection means for use in securing furniture sections together, as well as for registering them with relation to each other. In thismodification, a wedge shaped boss 5! is formed on, or secured to an end member 52 of a back section of fumiture and this boss is provided with a complemental tapered seat 53 in the adjacent wall of end section 54 so that the load on the back section, and the section itself, is supported in shear. A nut 55 or other tapped anchor member is suitably secured within the end section 54 so that a wing bolt 56 may extend through aligned holes in the boss 5| and seat 53 and engage the nut 55 to secure the back and end sections together. As many bosses 5| and seats 53 as are required may be formed on the furniture sections and, like the bolts l5 shown in Figs. 1 through 4, may be used in a joint between three sections wherein a suitably shaped and positioned boss would be formed on an extended member on one of such sections for association with a boss and its seat.

Another quickly releasable type of means for securing furniture sections together, in this instance by use of interlocking wedge shape clips. is shown in Fig. 10. The clip comprises a pair of arcuate arms 6| mounted on a base plate 62 that in turn is secured to a furniture section 63. The arms Bl are outwardly flared at their outer ends and are in substantial contact at the lower portion of their outer sections but spaced appreciably farther apart at their upper ends to form a wedge shape receiving member. A complemental clip member 54 is mounted on a base plate 65 carried by a second furniture section 66. This clip member 64 is formed from a metal strip or other suitable material so that it has an enlarged tapered outer end portion 6! which is smaller at its lower end than at its upper end. The clip 64 then is adapted to be positioned in engagement with arms 6| by telescoping the portion 61 into the seat formed by the arms 6l' adjacent the base 62. Again, any desired member of clips could be used in securing furniture sections together by positioning complemental clips in proper relation on the sections to be associated but, in all events, a solid engagement results between the sections to be secured together.

Fig. 11 illustrates desirable means for securing a fabric cover to a metal frame member such as a side member H. A fabric cover 13 extends down the side H to a point immediately above a hole 12 and has an enlarged edge binding 14 formed thereon, which binding may include a wire or other suitable reenforcing agent. Then suitable securing means, such as a cap screw 15 is engaged with the tapped hole 12 formed in the member H to position an angle clip 16 to the side H with a leg 11 thereof engaging the binding E4 to secure it to the furniture frame.

From the foregoing, it is seen that the davenport I6 is much lighter in weight than previous types of davenports, and that the sections of the davenport can readily be separated, when desired, such as in moving the davenport from one home to another. Furthermore, practice of the invention contemplates the provision of a number of different styled, but interchangeable sectioned pieces of furniture so that, for example, a store could supply the special type of arms or back to a, piece of furniture, as desired by the prospective purchaser. Thus a novel, improved 'of the invention is not limited to, or by, the

specific embodiments disclosed, but is defined in the appended claims.
