CONVERTIBLE COUCH Filed Nov. 2. 1959 2 Sheets$heet 2 ATTORNEYS United States Patent 3,048,855 CONVERTELE COUCH Edward Frank, 2400 American Ave, Long Beach, Calif. Filed Nov. 2, 1959, Ser. No. 850,367 3 Claims. (Cl. -7)

This invention relates generally to furniture and more particularly to a plural section couch that is convertible to an upholstered bench.

It is a primary object of the invention to provide an artistically designed plural-section couch that is quickly converted into an attractive bench by simple manual positioning of the backrest of each section. The conversion of couches to different furniture elements is usually accomplished by single unitary movement and with considerable physical effort. In prior structures of this type it has always been difiicult to preserve the over-all artistic appearance because of the necessity of using heavy adjustment fixtures and the difiiculty in housing same.

It is a major object of the present invention to provide a novel and improved convertible couch that eliminates the disadvantages of heretofore proposed articles of this nature.

A more particular object is to provide a convertible couch wherein the couch frame is hingedly connected to the lower end of the backrest and the rear of the cushion support so that manual movement of the backrest automatically moves the cushion support to a cushion concealing position.

Another object of the invention is to provide a convertible couch with simple, light-weight conversion mechanism of such small dimension that the over-all artistic design of the couch is not affected.

Still another object of the invention is to provide a convertible couch that is converted to a handsome bench with a minimum of physical effort.

A further object of the invention lies in the provision of a plural-section convertible couch in which each section is individually convertible to bench-defining position.

A still further object of the invention is to provide a connecting hinge mechanism that permits concurrent automatic movement of the backrest and cushion supports between their different positions.

Another object of the invention is to provide a lightweight dual hinge mechanism for each couch section, the hinges simultaneously connecting the frame, backrest and cushion support so that manual movement to converted positions is accomplished with minimum effort.

Still another object of the invention is to provide a hinge connection of couch frame, backrest and cushion support whereby manual movement of the backrest to a bench-defining position causes the cushion support to be withdrawn, and movement thereof to a backrest defining position causes the cushion support to be tilted to a comfortable seating position.

Yet another object of the invention is to provide a legsupported shallow frame having movable backrest and cushion supports hingedly connected thereto in such manner that manual collapse of the backrest on the frame withdraws the cushion supports from a tilted seat position on the frame to a cushion concealing position below the backrest.

With the foregoing objects in view, and such other objects and advantages as will become apparent to those skilled in the art to which this invention relates as the specification proceeds, the invention consists essentially in the arrangement and construction of parts all as hereinafter more particularly described, reference being had to the accompanying drawing in which:

FIGURE 9 is a vertical sectional view taken on the line 99 of FIGURE 1.

Referring to the drawings, and particularly FIGURE 1 thereof, a preferred form of convertible couch embodying the present invention is shown with the plural seat and backrest defining elements disposed in various positions of adjustment. The convertible couch broadly includes a rigid frame X preferably of wooden construction; a plurality, such as three backrests A, B and C; a cushion support D, E and F for each of the backrests A, B and C, respectively; and a seat cushion G for each of the backrests A, B and C. The seat cushions G are identical. In the interest of clarity only one such cushion is shown in the drawings. The lower end of each backrest is hingedly secured to the rear portion of the frame and to the rear end of its respective cushion support by means of a hinge structure S. With this arrangement, the backrests A, B and C may be moved between a couch-defining position represented by backrest A in FIGURE 1, and a bench-defining position represented by backrest C in this FIGURE.

More particularly, the frame X includes leg supporting ends 10 and 11 which are identical in design. The ends 10 and 11 have flat longitudinal lower edges 12 and 13, respectively, and upwardly flared lower side portions 14 and 15, respectively. The artistic design of the ends 10' and 11 includes downwardly flared upper side portions 16 and 17', respectively. The ends 10 and 11 have thickened areas 18 and 19 adjacent their rear edges, and flat upper edges 24) and 21, respectively, sloping downwardly and forwardly to present an artistic appearance.

The frame ends it and 11 are connected at the rear, in any conventional wood working manner, to a frame back 22 which flares outwardly and upwardly as shown in FIGURES 7, 8 and 9. The frame back 22 conforms in width to the ends 10 and 11 and at the top thereof has a continuous flat forwardly projecting portion 23 tapered sharply to a knife edge 24. The frame X has an outwardly flared front member 25- connected in standard manner to the forward inner edges of the ends 10 and 11. The front frame piece 25 is narrower than the ends 10 and 11, as shown in FIGURE 8, and has a flat continuous upper edge 26. The frame X is completed by dual transverse cross-pieces 27 and 28 spaced in a uniform manner between the ends 10 and 11. Cross-pieces 27 and 28 conform in general to the outer configuration of the frame ends 10 and 11 with the exception that they are shortened at the rear where they are attached to the back frame 22. The cross-pieces 27 and 28 are notched at 31 aand 32 to connect with the rest upon the front piece 25. However, they are in alignment with the upper edge surfaces 20 and 21 of the ends 10 and 11, respectively.

The frame X is supported by a pair of identical leg members L and L. The members L and L include frame supporting cross pieces 33 and 34 which are grooved transversely on their inner sides at 35 and 36, respectively, to receive and be connected with the frame ends it) and 11. The grooves 35 and 36 conform to and support lower edges 12 and 13, and the sides 14 and 15, respec tively, of the ends 10 and 11. The connection may be made by gluing, pegging or any conventional woodworking operation. The cross pieces 33 and 34 have dual legs 37 and 38, and 39 and 40, respectively, flared outwardly therefrom.

An inspection of FIGURES l, 2 and 3 will indicate that the backrest sections A, B and C are identical in every respect and for this reason the description will be limited to the single section A. It is also apparent that the convertible couch can be produced with any desired number of sections without departing from the spirit and scope of the present invention.

Backrest A has a solid panel 41 that preferably is a solid wood member having a longitudinally disposed raised strip 43 adjacent its lower or rear end. The outer edge 44 of the raised strip 43 substantially coincides and merges with the adjacent knife edge 24 of the frame back 22. The raised strip 43 conforms the panel 41 to the configuration of the ends 10 and 11, and the cross pieces 27 and 28, respectively. The backrest panel 41 has a surface 46 that is flat throughout its entire area. The front lower edge 47 of the backrest panel 41 is adapted to rest on the upper edge 26 of the front frame member 25 and is therefore angled slightly at 48 to coincide therewith in outer conformity.

The cushion support D is an open frame formed of back and front portions 49 and t and connecting side members 51 and 52. As stated before, any conventional woodworking method may be used in joining the described parts. The front edge of the portion 58 is angled slightly at 53 and a pair of plastic buttons 54- and 55 are secured thereto. The plastic buttons 54 and 55 are adapted to engage and slide on adjacent tapered plural guides '56 secured on the inside of front frame member 25. The plastic buttons 54 and 55 insure easy movement of the front edge 53 of the cushion support up and down the guides 56 to positions of use shown in FIGURES 4, 7, 8 and 9. The cushion support D has a series of cross-lapping strips 60 secured in the usual manner at 61 in the inner edges of oppositely disposed framing members 49 and 50, and 51 and 52, respectively. These strips 60 may be formed of any suitable material such as synthetic plastic or fabric.

The convertible couch hinge structure includes dual sets of hinges S and S for each backrest A, B and C. The hinges S and S are substantially ientical with the exception that their disposal on either side of the backrest requires slight structural changes. Hinge S includes a flat attachment plate 65 apertured at 66 for reception of plural frame securing screws 67. An elongated horizontal-1y disposed slot 69 is stamped or otherwise formed in the base of the plate 65. The plate 65 is also formed with a bore 70 to receive a hinge pin 71 welded at 72 to an inner hinge plate 73. The hinge pin 71 extends through the bore 70 formed in the upper front portion of the plate 65 and projects outwardly into a recess 75 in the frame end 11, as shown in FIGURE 6'. The inner hinge plate 73 has an inwardly bent flange 76 drilled in a plural manner at 77 to recive screws 78 which provide means for securing the hinge plate 73 to an outer rear edge portion of the backrest panel 41. The hinge plate 73 is formed with a camming aperture 79* in its lower portion. The edges 80 and 81 of camming aperture 79 control the movement of a follower pin 82 welded at 83 to a flanged bracket 84 which is apertured at 85 to receive attachment screws 86 that secure the bracket to the rear outer end 87 of cushion support D. The follower pin 82 projects through the camming aperture '79, the slot 69 in the attachment plate 65 and finally is received in a groove 88 in the frame end 11, as shown in FIGURE 6. The camming aperture 79 is enlarged to permit passage of a screwdriver in the insertion of the screws 67 The parts and method of attaching the hinge S are substantially identical as heretofore described with the following exceptions: The outer attachment plate 65 has plural screw apertures 66', 67' and 68 disposed in a different staggered arrangement to avoid contact with screws in adjacently disposed hinges on the cross-pieces 27 and 28. The hinge arrangement is best shown in FIGURE 3. The flange 76' of the inner hinge plate 73' is bent in the opposite direction to form a securing means on an outer edge 90 on the backrest 41.

The operation of the spaced hinges S and S controls the movement of the cushion supports D, E and F. Actuation of the hinges is initiated by manual movement of the backrests A, B and C. If the backrest A is disposed initially in the position shown in FIGURE 9, the front edge 53 and plastic buttons 54 and 55 0f the cushion support D are disposed in a seated fixed position on the upper edge 26 of the front frame 25. The follower pin 82 is held in locked postion in the front end of the slot 69 in the attachment plate 65 by means of the rear edge 80 of the camming aperture 79. Closing movement of the backrest A by folding it downwardly and forwardly to a benchdefining position results in a hinge movement as shown in FIGURES 8 and 7. Thus, referring to FIGURE 8, each of the follower pins will be cannned rearwardly by its contact with the sides of the camming aperture 79 since its outer end is slidably disposed within its respective horizontal slot 69. Hence, the rear end of the cushion support D will be concurrently urged rearwardly as its backrest A is folded forwardly. During such rearward movement the front end of the cushion support E will slide downwardly and rearwardly over the guides 56. When the backrest A has been folded completely flat, as shown in FIGURE 7, the cushion support E will have been lowered sufficiently as to provide clearance for the back cushion of the backrest C within the confines of the frame X, and such back cushion will be concealed from view. In the closed or bench-defining position of FIGURE 7, the rear edge '44 of the backrest C almost coincides with the knife edge 24 of the rear frame 22.

Back cushions 100 are either fixedly or detachably secured to the front surfaces of the backrests A, B and C. The seat cushions G are disposed on the cushion supports D, E and F, respectively, between the cross-pieces 27 and 28 when the backrests are in rearward elevated positions, as shown in FIGURES l and 9. When the couch is converted to a bench, the seat cushions are removed and the backrests A, B and C with attached back cushions 100 are folded into the position shown in FIGURE 7. In this position these back cushions are completely hidden from view. Clearance for so concealing these back cushions is provided by the movement of the cushion supports D, E and F from their upwardly and forwardly tilted position of FIGURE ,9 to their more nearly horizontal position of FIGURE 7. The backrests now form a substantially uninterrupted horizontal surface and the loose seat cushions G may be placed on the backs of the backrest-s. If desired, one or more of the seat cushions may be left off of the backrests whereby a table surface will result. Should all three seat cushion-s be left off the backrests an aesthetically pleasing cofiee table will thereby be provided.

From the foregoing description it will be apparent that the operation of the convertible couch is simple. Each section is *an individual unit and a minimum of physical effort is required to move the backrest between an upwardly extending position and their horizontally extending position. The hinges are so light in weight and so arranged that they are substantially hidden at all times. The plural sectional arrangement and the dual lightweight hinges provide conversion means that requires a minimum of physical effort.

Since various modifications can be made in my invention as hereinabove described, and many apparently widely difierent embodiments of same made within the spirit and scope of the claims without departing from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense.
