9 Claims.

This invention relates to improvements in furniture and more particularly to the construction of furniture employing a metal frame, and is a further improvement of the metal furniture disclosed in this applicants prior Patent No. 1,934,195, granted November '7, 1933.

Said prior patent discloses a chair having a seat frame including a plurality of metal shapes bent in the form of flat arches with angular legs depending therefrom with the legs of the arches adjacent each other interlocked to form the respective legs of the chair. It is an object of this invention to employ a framework of this character in which the interlocking leg portions of the fiat arches are terminated after the interlocking has been accomplished and in which the opposite or diagonal interlocked leg portions are connected to each other by structural metal shapes bent in the form of flat inverted arches with the leg portions thereof secured to the embracing leg portions of the seat frame. It is also an object of this invention to provide the corners of the seat frame with members which may be extended to form integral legs or which may be employed for attaching and securing legs of wood or other material to the corners of the seat frame.

It has been found in practice that a seat frame formed of a plurality of structural metal shapes bent in the form of fiat arches with angular legs depending therefrom with the legs adjacent each other interlocked with the addition of transverse braces of structural metal shapes bent in the form of inverted fiat arches not only stiffens the frame, but produces a very light-weight rigid structure. hereinafter described, the metal frame is readily adaptable to he supported on legs of metal, wood or other material which may be readily attached thereto and provides at the same time similar means for attaching either metal or wooden backs and arms to the seat frame.

With these and other objects in view. reference is made to the accompanying sheets of drawings, with the understanding that detail changes may be made without departing from the scope thereof.

The form of this invention as illustrated in Figure 1 shows a chair having a seat frame formed of four bent channels I each in the form of a flat arch having their flanges extending upwardly and outwardly and arranged so that the channels forming the sides of the frame will telescope the adjacent flanges of the channels forming the front and back of the frame and in the telescope position are secured to each other, preferably by spot welding or tack welding. The interlocking portions are terminated after one has been wholly received within the other, as shown in Figures 1 and 3.

Overlapping diagonal braces 2 and 3 formed of bent channels each in the form of a flat inverted arch having their flanges extending downwardly and outwardly are provided. The webs of the channels at their extremities are indented to receive the angular corners of the interlocked channels of the seat frame arches with the flanges of thechannels of the indented web engaging the sides of said interlocked seat frame arches and are secured to the interlocked seat frame arches by tack welding, shown in Figures 1, 2 and 3. Where the diagonals 2 and 3 cross each other the flanges of the upper channel are cut and bent upwardly to receive the flanges and Web of the lower channel, as shown in perspecof sleeves attached to the corners of the seat frame for receiving and supporting the legs of wood or other material.

In Figures 1, 2 and 3 the corner members for the front of the seat frame are cylindrical metallic sleeves 4, while the corner members for the back of the frame are rectangular metallic sleeves 5, as shown in Figures 2 and 3. The cylindrical sleeves 4 are provided with vertical slits 6 to receive the outer flanges I of the channels I and the rectangular sleeves 5 are provided with similar slots 8 for the same purpose. The sides of the seat frame are enclosed by skirts extending from the top of the flat arches l to the termination of the legs of said arches. These skirts 9 may be of. metal, metal covered with a wood veneer, wood or may be of other material, as dey sired. The slits 6 and 8 in the corner members 4 and 5 are of sufficient width to firmly embrace both the flanges l and skirts 9. The corner members are held rigidly in place by notched locking members l0 mounted upon diagonal corner braces II which are secured upon the underside of the web of the channels I. The locking members ID are notched upon the underside to be engaged in notches l2 in the top of the corner members 4 and 5, as shown in Figures 1, 2 and 3. It is preferable to form the slit receiving the front and side skirts in the front corner members extending downwardly from the top of these members. If desired the rear corner members may be slotted instead of slit and the engaging portions. of the skirts 9 may be shouldered, as shown in Figure 3. The skirts 9 are preferably held in engagement with the upper fiat portions of the flanges I of the flat arches by caps [3 having depending front and back flanges M to embrace the outer surface of the skirts 9 and the inner surface of the channel members I, as shown in detail in Figure 5. If the skirts 9 are wood they may be supported by diagonal corner braces l5 mounted on the webs of the inverted diagonal arches 2 and 3 with the free ends attached to an inwardly shouldered portion at the bottom of the skirts 9, as shown in Figure 5, and if the skirts are metal, a wooden strip may be attached thereto to form the shouldered portion.

Cushion supporting springs may be readily attached to the diagonal corner braces H which support the locking members ID of the corner members, as shown in Figure 1. The springs are preferably in the form of diagonal strips l6 of metal, the opposite ends of which mount coil springs H. which are hooked into the diagonal braces II, as shown in Figures 2 and 5.

The posts ill of the chair back are preferably rectangular in shape of sufficient size to be received within the rectangular corner members 5 of the back of the chair frame and are cut out at their lower ends to receive the side skirts 9 and that face is bevelled to engage the inner surface of the corner member to impart the correct angle. When the back posts are of metal, as shown in Figures 2 and 3, they may be tack welded or spot welded to the side of the member 5. It is to be noted that in Figure 2 the rear of skirt 9 engages the inside of the rear wall of the post when the opposite side is in engagement with the inner side of the member 5. When the posts are of wood they may be secured to the corner members 5 by screws. The chair shown in Figure 1 is provided with arms l9 which extend forward from the back posts 18 and then downwardly to pass over and terminate in line with the lower edge of the side skirts 9. The arms may be attached in any desired manner to the back posts and it is preferable to provide an angular brace 29 secured upon the diagonal flat arches 2 and 3 adjacent the front corner members with the horizontal portions secured on the upper side of the diagonal flat arches 2 and 3 adjacent the front corner members 4 and the vertical portions extending upwardly at the front of each side skirt 9, perforated to receive screws which may be passed therethrough and through the side skirts to engage the lower portions 2| of the arms I9, as shown in Figures 1, 2 and 3.

In Figure 1 legs 22 of Wood or composition material are shown inserted in the lower ends of the socket-like corner members 4 and 5.

In many instances the seat frames of chairs are wider in front than they are at the back and it therefore may be desirable to employ a somewhat different form of connection for the front corner members than that shown in the first three figures. Figures 6 and 7 illustrate the use of an additional brace 23. In this form the brace 23 is in the form of a right angular structural shape having the free ends provided with right angular extending flanges which are adapted to bear against the vertical portions of the interlocking legs of the flat arches I so that when the securing member ID is hooked into the notch in the upper portion of the cylindrical corner member 4 it will hold the corner member firmly against the flanges of the arches in engagement with the bracing member 23. Figures 6 and '7 also illustrate a modified means for supporting the skirts 9. The skirts 9 are approximately twice the thickness at the top and the underside of this portion is grooved to receive the outer flange I of the flat arches l, as shown in Figure 7, so that the skirts are hanging from the flange. The ends of the skirts are shouldered at the top, as shown in Figure 6, so that the thickened top portion will clear the re-enforcing member 23.

Figure 8 illustrates the means of connecting a rectangular metallic rear corner member. A sleeve 24 may be likewise connected when it is desired to substitute this form of sleeve for the cylindrical sleeves 4 forming the front corner members. The rectangular sleeve 24 is notched at one corner to be engaged by the notched looking member I supported upon the diagonal corner brace I I.

Figures 9 to 17 illustrate the application of wood or composition legs which may be substituted for the metallic sleeve type of corner members. In Figure 9 a wooden leg 25 rectangular in cross-section is shown having vertical grooves 26 to receive the side and front skirts 9 and outer flanges I of the flat arches I. The top is provided with a diagonal groove 21 to receive the locking member ID supported upon the diagonal corner brace I I. In this type it is preferable instead of notching the underside of the end of the locking member ID to provide it with a right angular extension 28 and provide the center of the leg with a circular depression to receive the angular portion whereby the locking member will hold the upper portion of the leg firmly in place. It is also preferable to provide apertures in the webs of the interlocking flat arches I through which screws 29 may be inserted to engage the body of the wooden leg to secure the same to the corner of the chair frame, as shown in Figure 11.

Figures l2, l3 and 14 illustrate ameans for securing a wooden leg to the corner of the chair frame when it is undesirable to use the diagonal corner brace. A bracket having side members 30 adapted to engage the inner sides of the outer flanges I of the channels I are joined by flat portion 3|. The side members 3|] are provided with inturned flanges 32 which are adapted to be secured to the fiat portions of the upper side of the web of the channel members and the wooden leg 25 is provided with side grooves 26 of suflicient width at the top to receive the ends of the skirts 9, outer flange 1 of the channel member I and the side members 30, of the bracket. These grooves are connected by another groove 33 in the top of the leg to receive the flattened portion 3| of the bracket whereby the top of the leg is held firmly in place in the corner of the frame. Screws 29 may be passed th ough apertures in the interlocking webs of the channel members I to hold the leg in place in the same manner as shown in Figure 11.

Figures 15, 16 and 17 illustrate a modified form of this bracket connection in which the sides 30 are joined by a re-entrant angle portion 34 which, as shown in Figure 15, embraces the corner of the wooden leg 25 and this re-entrant portion is secured by a screw passing through the body and into the leg 25. In this form the rectangular portion of the leg is held in engagement with the webs of the interlocking legs of the channel members I by screws in the same manner as shown in Figures 11 and 14.

When the legs or sleeves for supporting the legs are of hollow metal and'are of rectangular shape in cross-section they may be readily secured to the corners of the seat frame, as shown in Figures 18, 19 and 20. This form of connection includes a bracket having a horizontal portion 36 which extends over the upper side of a web of one of the channeled flat arches I and is secured thereto. The horizontal portion is then bent back upon itself and then bent at right angles to form a vertical portion 31 to rest against the vertical portion of the web of the channel and the bracket then terminates in an angular horizontal extension 38 preferably of similar extent to the bent back section of the horizontal portion at the top and may be bent back upon itself in the same manner, as shown in Figure 19. The side of the rectangular hollow leg 39 is provided with apertures 40 through which the bent back portions 4| of the bracket may pass. It is preferable to provide an angular brace 42 bearing against the inner and adjacent sides of the hollow leg having similar perforations to receive the bent back portions 4| of the bracket. The sides of the hollow leg 39 are slotted to receive the outer flanges I of the interlocked flat arched channels forming the seat frame and the skirts 9, as shown in Figure 18. When the leg has been assembled a tapered drift pin 43 is inserted through apertures provided therefor in the bent back portions 4| of the bracket to allow the pin to tightly draw a side of the hollow leg against a vertical portion of the angular brace 42 to hold the upper portion of the leg in rigid engagement with the vertical portion 31 of the bracket.

A rectangular wooden or composition leg may be readily attached to the corner of the seat frame without recessing the leg to receive the outer flanges I and skirts 9, as shown in Figures 21, 22 and 23. In this form of connection a clip having integral right angular portions 44 and 45, with each portion provided with upper and lower right angular extensions 4Band 4'! is employed. The extensions are of such dimensions that the upper right angular portions 46 will extend over the upper side of the fiat portions of the webs of the interlocked flat arches of the channel members I to be secured thereto with the portions 44 and of the clip held in vertical position to engage the edges of the vertical portions of the outer flanges I of these members and extend therebeyond on each side to form an anchor for the ends of the skirts 9. The bottom extensions 41 are formed to pass over the terminations of the vertical portions of the seat frame and act as a support for the bottom of the skirts 9. One side of the rectangular wooden leg 48 is provided with an arcuate cut out recess 49 adapted to receive a metallic key 50 which is provided with upper and lower outwardly extending lugs 5| and 52, each of which is provided with recesses 53 upon the upper sides thereof in line with the outer surface of the leg 48, as shown in Figures 22 and 23. The portion 45 is provided with twoslots 54 through which the lugs 5| and 52 may be inserted and when the surface of the leg 48 is in engagement with the adjacent surface of the section 45 the leg 48 may be forced upwardly to engage the body of the portion 45 in each of the notches 53 in the lugs. To secure the leg in this position the portion 44 is provided with an aperture 55 in line with a similar aperture 56 in the web of the vertical portion of the flat arch I which is parallel to the key 50 so that a screw 51 inserted through the apertures 55 and 55 may be screwed into the body of the leg and engage an aligned aperture 58 in the key 5|! which will not only hold the key in place against the clip 45, but will also draw the leg against the clip 44. The outer edges of the portions 44 and 45 are each provided with slots 59 and 611' which are adapted to receive the heads of screws 6| screwed into the ends of the skirts 9 to support the ends of the skirts 9. As shown in Figure 23, the lower edge of the skirts 9 are provided with a shouldered portion which extends under the bottom extensions 4! and may be attached thereto by a screw, as shown. An obvious modification of this type of support is to form the key 50 integral with the right angular portion 45 by striking the key upward from the outer free edge at right angles to the portion 45.

This invention also contemplates the omission of the chair back and arms to form a footstool or a hassock as well as to increase the dimensicns of the seat frame to form couches and also to attach head and footboards to the couch frame corner members in the same manner as the above described chair back to form studio couches and beds. It is obvious that when desired the corner members at the back may be extended in an upward direction to form the side posts of the back of a chair or may act as sockets to receive back posts of wood or other material, without departing from the scope of this invention. Likewise, the front corner posts may be extended upwardly to form the front support for the arms of a back or may act as a socket for receiving and supporting such front supports of wood or other material, without departing from the scope of this invention.
