16 Claims.

I This invention relates to a couch, and especially to means whereby the couch maybe manipulated or extended to provide a bed.

An object of the invention is to provide an extensible couch or the like with novel actuating means whereby a tractional or movable section of the couchmay be extended or retracted with the expenditure of a minimum of time and effort, and without requiring the operator to stoop or to lift any part of the couch.

Another object of the invention is to accomplish the foregoing object by the employment of means which are simple and inexpensive,

, durable, and of such character as to be either normally concealed, or exposed in such a manner as to enhance the appearance of the couch.

The foregoing and other objects are attained by the means described herein and disclosed in the accompanying drawings, in which:

means of the invention.

Fig. 4 is a fragmental perspective view showing a, second form of actuating means.

Fig. 5 is a fragmental elevational a third form of actuating means. 30 Fig. 6 is a plan view of the couch, with the covering material removed, showing a construction adapted for use with either actuating means of Figs. 4 and '5.

Fig. 7 is a perspective view of a modification.

The couch, or so called studio couch, illustrated in the drawings, comprises a stationary frame 8 and a relatively movable frame 9 which, if desired, may be rendered tractional by the provision of suitable rollers Ill. The movable or tractional frame 9 may comprise the various legs l2 which support a rectangular structure l3 having associated therewith any suitable type of mattress supporting means M. The means l4 illustrated in the drawings, is a wire fabric attached to the rectangular frame elements by means of a multiplicity of springs IS. The movable frame may conveniently be built of angle iron sections.

The stationary frame may comprise a suitably upholstered seat portion l6 having front legs l1 and rear legs 20, or an equivalent structure for spacing the seat structure from the floor a distance suflicient to permit retraction of the movable frame to a position beneath the seat structure [6. The stationary frame 8 may inview showing Fig. 3 is a perspective view of an actuating cludea back rest, if desired, which may be in the form of a panel or a rail such as l8 supported at its ends upon rear uprights l9.

right-s referred to may provide also the The uprear legs 20 of the stationary frame, (see Fig. 1). It will be noted that the rail it,

when the rail type of back rest is utilized, is spaced from the plane of the seat portion it. The vide a support for pillows upon the seat portion l6 rail is adapted to prowhich stand on edge near the rear thereof.

The stationary and movable frames are adapted to be connected together in any suitable manner, to limit the movement of the frame outwardly, and to frame when moved relative to the frame. To this end, scissors arrangement of tractional guide and stabilize said stationary there is provided the crossed bars 2! and 22.

As is most clearly illustrated in Fig. 2, the bar 2| has its rear end pivoted at 23 upon. or relative to the stationary frame 8, adjacent the rear portion thereof,

and the bar 22 has its forward end pivoted at 24, upon or relative to the inner frame member 25, of the movable frame 9. The opposite ends of the crossed bars are received. in the slots 26 and 21 of the stationary and movable frames, in the frames, if desired, or they may respectively. Such slots may be formed be formed in separate parts attached to the frames, in accordance with common practice.

Each bar may carry a lug 28 to ride in its associated slot. From the foregoing, it, will be evident that retraction of the movable frame 9 to a position beneath the stationary frame 8, in Fig. 2, will cause the lugs 28 of the crossed bars to travel along the slots 26 and 21,

the movement to a position at the extreme lefthand end thereof (referring to Fig. 2).

referred to, the frame 9 During will be definitely stabilized and guided to its retracted position.

The stabilizing and guiding function occurs also upon extending the movable frame.

It should be noted that the crossed bars 2| and 22 are pivoted together at a point 29 intermediate their ends.

In accordance with the invention, means are provided for mechanically extending and re.-

tracting the movable frame 9. may be referred to generally The said means as, an actuating means which, in Figs. 1, 2, and 3, comprises a horizontal handle or lever 30 to be swung through substantially a quarter-circle arc, and arranged frame when disposed in to retract to the dotted line posi- Particular in the inoperative or dotted line position indicated, the handle or lever is disposed substantially within or parallel to the plane of the back rail I8, in such a manner that it will not interfere with the placin of cushions against the back rail. When the handle or lever 30 is moved to the forwardly extended position of Figs. 1 and 2, it is substantially parallel to the side of the couch, so as not to interfere with the use thereof as a bed.

The handle 30 is operatively connected to the movable frame 9 by means of a horizontal swing bar or the like 32. Both the swing bar and the handle are fixedly mounted upon a vertical pivot rod 33, the ends of which pivot rod are journalled in bearings 4 and 5 carried by the upright or standard I9. The bearings may be individual or separate, as shown in Fig. '7, or they may be in the form of perforated extensions 36 and 31 of a bracket 38. The members 30 and 32 may be fixed to the pivot rod in substantially parallel and spaced relationship. The means providing the bearings may be screwed, bolted, or otherwise secured to one of the rear uprights, for example, upright 20. Thus, the pivot rod 33 is enabled to rotate through an arc of approximately ninety degrees (90), while handle 30 and the rod 32 swing in substantially horizontal planes.

At the free end of the swing bar 32 there is provided a follower M, which may be in the form of an upwardly or downwardly turned section of the bar, the follower being adapted for movement within a guideway or track 42 associated with the movable frame 9. The guideway or track may be made in various forms, there being shown a satisfactory construction comprising a member 43 spaced from the rail but secured thereto by means of rivets or other fasteners 44. The spacing between member 43 and rail 25 is sufficient to receive the follower M of the swing bar, and the guide bar may be of a length approximating the length of said swing bar 32. The construction just described provides for automatic retraction and extension of the movable frame 9, when the lever or handle is moved from the full line position of Fig. 1 to the dotted line position indicated at 3|, and vice versa.

The horizontal swing bar 32 preferably, but not necessarily, moves in substantially the plane of the supporting surface I4 of the removable frame. This results in extreme simplicity, elimination of parts, and compactness of the structure. It is to be understood that the guideway or track 42-43 may be dispensed with if desired, by connectingthe free end of the swing bar to the movable frame otherwise than as illustrated in Fig. 1, for example, by means of a link 39 (Fig. '7) pivoted at its ends to the swing bar and to the frame or scissors structure. Also, the guideway or track may take other forms that will readily suggest themselves after a study of the present disclosure. The exact shape or configuration of the handle 30 is immaterial to the invention.

In accordance with Fig. 4, which is a modification, the handle I30 extends forwardly of the couch while the swing bar I32 is in the inoperative or retracted position. In other words, the swing bar and the handle are fixed to the vertical pivot rod I33 at right anglesto' one another. It will be noted also that the actuating handle I30 is turned upon itself as at 45, so as to extend about the rear upright I9 and then project forwardly and downwardly, terminating in a forward end 46 which may abut the stationary frame 8. The reference character 41 indicates a latch of conventional design, for detachably fixing the forward end of the arm to a part of the stationary frame. In this construction, the bracket I38 is the same as that of Fig. 3, but the arrangement of the actuating lever or handle I30 is such that the tractional frame (not shown on Fig. 4) will be extended upon swinging movement of the handle or lever I30 outwardly from the side of the couch. Thus, when the device is extended, the handle or lever I30 will assume a position outside the body line of the couch but substantially in the plane of the back rest I3. It will be understood that the actuating mechanism of Fig. 4 is adapted to be associated with the movable and stationary frame parts in the manner disclosed in Figs. 1 and 2, or its association with the couch parts may be in accordance with the teaching of Fig. '7.

Attention is now directed to the modification illustrated by Fig. 6 wherein the swing bar 48' is arranged to apply force upon the scissors arrangement comprising the bars 49 and 50, at or near the pivotal connection 5| thereofjinstead of applying such force directly upon the movable or tractional frame; The scissors arrangement of the Fig. 6 construction is identical with that of Fig. 1 and Fig. 2, wherefore the explanation thereof need not be repeated. It will be understood, however, that by connecting the swing bar 48 to the pivot 5| or to the scissors arrangement, the vertical pivot rod 52 (which corresponds with the rods 33 and I33 of Figs. 3 and 4) is greatly limited in its rotational movement. The approximate movement of the swing bar 43 is'indicated by the angle between the full line position of Fig. 6 and the dotted line position thereof as indicated by the character53. Because of the limited swinging movement of the swing bar, and of any handle that might be associated therewith, it will be seen that a handle such as that of Fig. 1 could not conveniently be employed, as it would objectionably extend across the bed and within the body lines thereof- The invention contemplates the application of a handle means of the Fig. 4 character, however, to the Fig. 6 construction, for such a handle would swing outwardly of the side of the couch upon extension of the movable frame. The manner of applying the handle I30 of Fig. 4 to the Fig. 6 construction is indicated generally by the broken lines I30. Should it be desirable, however, to apply the principle of the Fig.

is applicable. In accordance with Fig. 5, the actuating handle or lever 54 is not fixedly secured to the vertical pivot rod 55, but has a sort of ratchet connection therewith. The connection may be more properly referred to as a lost-motion joint, one form of which is illustrated. Said joint may comprise a bayonet slot 56 in a tube 51 which surrounds and is fixed to the pivot rod, said bayonet slot being adapted to receive an extending lug or stud 58 carried by the handle or lever. By means of the lost-motion connection, the swing bar 59 may be moved through the limited are as explained in connection with the Fig. 6 actuating means, by movement of the handle 54 through a similar arc. Upon completion of I handle, to the Fig. 6 under- 7 structure, a means such as is disclosed in Fig. 5 I

said arcuate movement, however, the lug 53 would to the concealed position beneath the rail I8 of theback rest. It will be understood that the type of handle or lever action disclosed in Fig.5 is applicable to the particular construction shown in' Fig. 6 but that it could be applied also to the is manipulated to extend or retract the movable frame. It may be stated also that the slot 61 may be obviated, if desired, by connecting the free end of the swing bar to the or to any other part of the scissors arrangement, by means of the'pivoted connecting linkarrangement illustrated in Fig. 7.

In'conclusion, attention is directed to the fact that couches embodying the present invention need notbe provided with a back rest, (see Fig. 7). The upright or post l9 may be short, or just long enough to provide a suitable support for bearing means such as 34-35. In fact, the up right or post may be the rear leg of the couch, and the handle or lever back rest,

to the position stated.
