4 Claims.

The invention relates generally to a couch or sofa bed construction, and more particularly to novel means for connecting a seat supporting structure to a pair of arm members.

The invention is particularly adapted for use in sofa bed constructions wherein the seat member is supported by a frame structure constructed in the form of a box, which may be used for the storage of bedding, or the like, the box being, in turn, supported at opposite ends by suitable arm structures. In the past, sofa beds of the type here involved, which employ separable arm structures, have utilized bolts, or the like, for securing the seat supporting box structure to the arms, the bolts carrying not only tension load, but also carrying the shear load of the weight of the box and seat structure.

The present invention has, therefore, among its objects the production of a couch construction in which the seat loads are transmitted directly to the arm structure, whereby shear loads on the securing bolts are eliminated to provide an assembled couch that is very durable, providing maximum rigidity and durability.

Another object of the invention is the production of such a couch structure which is relatively simple in construction, readily assembled, and inexpensive to manufacture.

Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

To this end my invention consists in the novel construction, arrangement, and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts:

Fig. l is a perspective View of an arm structure and a portion of a bedding box, or the like, illustrating the details of construction;

Fig. 2 is a view similar to Fig. l of a portion of the bedding box;

Fig. 3 is a sectional view taken approximately on the line 3-3 of Fig. 4; and

Fig. 4 is a sectional view taken approximately on the line 5-4 of Fig. 3.

Referring to the drawings, and more particularly to Figs. 1 and 2, l indicates generally an arm structure to which is secured a seat supporting structure indicated generally by the numeral 2, the latter, when employed in a sofa bed structure which may be made up into a bed, beingeonstructed inthe form of a box providing a compartment for bedding, or the like. The drawings illustrate merely the framework of the arm structure and, in use, the latter would be covered with a suitable material, such as fabric, plastic, or the like.

The arm structure 1 comprises a bottom memher 3 supported by a front leg 4 and rear leg 5, and extending upwardly from the bottom member at the respective ends of the latter is a front upright 0r post 6 and a rear upright or post I, the uprights being connected by one or more relatively heavy arm members 8 having a top member or panel 9 of relatively light material overlying the same. The respective elements thus far described are rigidly secured together by any suitable means, as for example, dowling and gluing, or-

the like.

Extending between the uprights 6 and I adjacentthe bottom member 3 is a cross member or side rail l l, the connection of the latter with the uprights being reinforced by blocks l2 and I3 rigidly secured to their uprights and the bottom member, the cross member H and blocks being rigidly secured together by any suitable means. Referring toFigs. 3 and 4, it will be noted that the cross member I l is spaced inwardly from the adjacent edge I4 of the bottom member to form a ledge I5. Also extending between the uprights 6 and l and secured to the blocks l2 and I3 is an upper cross member or upholstery strip [5 to which the fabric, or other material, applied to the arm structure may be secured, the fabric extending over the panel 9 and down to the strip I5.

The box member 2, only one end of which is illustrated, comprises respective front and rear members or boards [6 and I1 connected adjacent their ends by respective end members or rails IS, the end rail not illustrated being constructed in the same manner as that shown in the drawings. The box is completed by a bottom l9 extending between the members I6, I1, and 18, all of the elements being suitably secured together to provide a rigid structure. Rigidly secured to the end member H! by screws 2! and gluing, or other suitable means, is a pair of upwardly extending blocks 22a and, 22b. The end rail i8 is provided with a bore 23 therein, and extending through the end rail and the block 22a is a bore 24, such bores being adapted to be aligned with

respective bores

25 and 26 in the cross member II when the box is in the position illustrated in Figs. 1, 3, and 4. When the box structure is mounted on the arm structure, the blocks 22a and 2% are positioned with their lower ends seating upon the ledge l5, as clearly illustrated in Figs. 3 and 4, with the blocks at their upper ends bearing against the cross member I5. The elements are maintained in such position by bolts 21, respectively positioned in the

bores

23 and 25 and bores 24 and 25, and

nuts 28, thus rigidly clamping the elements to-' gether. The front and rear members l5 and I! of the box 2 preferably project beyond the end member 58, as indicated at a and Na, whereby a neat butt joint between the respective uprights 6 and l of the arm and boards 5 and I! of the box will be formed. Obviously, when the uphol- 3 story is applied to the arm, the blocks 22a and 221) will bear against the covered strip is rather than directly on the strip, as illustrated.

It will be noted that all of the weight of the box 2, the seat members carried thereby, etc., are directly supported by the blocks 22a and 22b seating upon the bottom member 3 of the arm structure, so that such load is directly transmit ted from the box to the bottom member 3 and

legs

4 and 5, with the bolts 27? and nuts 28 merely securely holding the parts in assembled relation, as contrasted to previous structures wherein the bolts, in addition to securing the elements together, carried all the weight of the box, seat, etc., as a shear load. and 22b extending above the box and en aging the upper cross member i5 provide additional rigidity in the assembled structure, and eliminate any tendency of the upper portions of the armsto rock inwardly toward the center of the couch.

Obviously, the present construction provides a very rigid structure having much less tendency in use to loosen up than previous structures, wherein the connecting bolts were under shear as well as tension stresses. structed as iilustrated will retain its rigidity, and the arms will not become wobbly.

While I have illustrated merely one arm structure and one end of the box structure, the opposite end of the latter and the arm not shown would be constructed in the same manner as above described, with the exception that the cross members II and i5, and blocks 13 are reversed to position the cross member adjacent the opposite face of the arm. It will be noted from the above description that I have provided a couch structure which is very simple in construction, and extremely durable in use.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence, I do not wish to be understood as limiting myself to the exact form, construction, arrangement, and combination of parts herein shown and described or uses mentioned.

What I claim as new and desire to secure by Letters Patent is:

1. in a sofa bed construction, an arm structure including a horizontal bottom member, and front and rear uprights positioned at opposite ends of the bottom member, a cross member extending between said uprights and positioned adjacent said bottom member, said cross memher being spaced inwardly from the inner side edge of the bottom member, a seat supporting structure having a side member positioned adjacent the inner side edge of said arm structure, a pair of spaced blocks positioned at the outer face of said side member and rigidly secured thereto, said blocks having their outer faces abutting said cross member, and their lower ends resting upon said bottom member to support the seat supporting structure on said bottom member, and means passing through said cross member and side member for rigidly securing the same together.

2. In a sofa bed construction, an arm structure including a substantially horizontal bottom member, and front and rear uprights positioned at opposite ends of the bottom member, a cross member extending between said uprights and The portions of the blocks 22a 1 As a result, a couch conseated upon said bottom member, said cross member being spaced inwardly from the inner side edge of the bottom member, a second cross member positioned above the first cross member and spaced therefrom, corner blocks positioned at the junctures of said cross members and uprights and secured to the latter and said cross members, a seat supporting structure having a side member positioned adjacent the inner side edge of said arm structure, a pair of upwardly extending blocks positioned at the outer face of said side member and rigidly secured thereto, said blocks having their outer faces abutting both of said cross members, and their lower ends resting upon said bottom member to support said seat supporting structure on said bottom memher, and means passing through said first cross member and side member for rigidly securing the same together.
