Hofsis, Toledo, Ohio, assignors, by mesne assignments, to Globe-Wernieke Industries, Inc., Toledo, Ohio, a corporation of Ghio Fiied Jau. 22, 1962, Ser. No. 167,746 7 Claims. (Cl. 297-63) This invention relates to furniture but more particularly to a convertible chair-couch combination and an object is to produce an assembly of this character having a two chair arrangement in back-to-back relation which can be readily converted into a bed or couch of comfortable proportions.

Another object is to produce a convertible chair-couch arrangement which provides a two chair arnangement in one organization and which has a slide capable of being drawn out to afford a couch in which the backs of the chairs provide the covering for the slide.

A further object is to produce a chair-couch assembly which converts from a chair to a couch by pulling out a slide, parts of the chair being rockable upon the slide to aiford a covering therefor for establishing a couch.

iOther objects and advantages of :the invention will hereinafter appear and, for purposes of illustration, but not of limitation, `an embodiment of the invention is shown on the accompanying drawings in which FIGURE 1 is a side elevation of the chair-couch assembly with the parts in position for use as chairs;

,FIGURE 10 is an elevational view partly in section of a portion of the outer end of the frame showing the releasable latch arms and taken on the line 10-10 of FIGURE 7.

The illustrated embodiment of the invention comprises a couch-chair arrangement having la substantially rectangular main frame 10 of metal, the rails of which are generally U-shaped in cross section. The several rails forming the frame 10 have an inwardly extending horizontal flange -11 through which screws pass for securing an upholstered cushion 12 thereto, the latter extending from end to end of the frame 10. At opposite end portions of .the frame are supporting

legs

13 and 14, which, as shown in FIGURE 3, are generally U-shaped.

Mounted in the channel formed by the side rails of the main frame 10 is a metallic slide frame '15, the same being adapted -to shift horizontally along the side rails of the frame 10 from the position shown in FIGURE 1 to an extended position beyond one end of the main frame, as shown in FIGURE 2. The rails o f the slide frame |15 are L-shaped in cross section to have a sliding tit in the channel formed in the main fname rails. At `the outer end of the slide frame 15 is an end leg 16 similar in conguration to the

legs

13 and 14.

A generally rectangular metal-lic back frame 17 carrying an upholstered cushion 18 at one side is pivotally connected at '19 .to the inner end of the slide frame v1'5. The lower ends of the frame 17 are formed with rounded edge portions 20 to afford the desired pivotal movement, as will hereinafter appear, At one side of the back frame 17 is a second rectangular metallic back frame 21 which is somewhat shorter than the back frame 17. The back frame 21 carries an upholstered cushion 22 similar to the cushion 18. The

frames

17 and 21 are connected together at their upper ends by a hinge 23. When the back frames are in raised position to provide two seat backs, the frames I17 and 21 incline downwardly and outwardly relative to each other.

Pivotally connected to the lower end of the back frame 21 on each side is an arm 24 which is generally of inverted U-shape. The pivotal connection `to the frame 21 is indicated a-t 25 land the opposite end is pivotally connected at 26 to the slide frame 15. Intermediate the ends of each arm24 is an outwardly-struck stop to provide a shoulder 27 for abutting engagement with the upper edge of the slide frame 15. The stops 27 not only properly position the back frame 21 in the Idesired position but also assist in the support thereof when the back frames are in raised seat position.

When the slide frame '15 is slid inwardly to the position shown in FIGURE 1, stops 2S are provided on each side of the main frame 10 for limiting the movement of the slide frame so that the

back frames

17 and 21 are properly positioned relative to the main frame. As shown (FIG. 4) each stop piece 28 is of sheet metal and is secure-d to the main frame by bolt and nut assemblies 29. Each stop piece has a raised lip to receive the adjacent end of the slide frame 15 and hold it in place.

The slide frame is secured in the chair position by pivoted latch *arms 36 which are pivoted at 31 to the slide frame 15; The arms have depending ho-oks 32 which are adapted to extend through holes provided in the main frame 10, thereby positively -to retain the slide frame 15 in the desired position. Each of the latch arms 30 has a handle 33 to enable it to be conveniently manipulated.- Each arm 30 is spring loaded and, as shown, a rubber block 31a is disposed under each arm and mounted on the slide frame 15 for urging the respective arm out of latching position.

It will be understood that in order to convent the assembly from use as a two seat Ychair arrangement as shown in FIGURE l, -to a couch position, the latches 3i) are first released. Thereafter the slide frame 15 is moved to the right of FIGURE 11 to the position shown in FIGURE 2. The

back frames

17 and 21 are rocked to a iiatwise position with the cushions in alignment with the main cushion 12. It will be apparent that the back frame 17 rocks about its pivotal connections 19 and the back frame 21 Aswings upon its hinge 23. As the frame 21 is extended to the right of FIGURE 2, the arms 24 rock about pivots 26 so that finally the pivotal connections 25 are disposed outermost and the two

frames

17 and 21 abut against each other so that the ends of the

cushions

18 and 22 are brought closely together. Manifestly by reversing the operation and moving the slide 1/5 to the left of FIGURE 2, the

back frames

21 and 17 may then be rocked to their upright or chair position as shown in FIGURE 1.

An alternate form of latching mechanism is shown on FIGURES 7 to l() and, in this instance a pair of tongues 314 and 35 are struck from the flat portion of the slide 15, on each side thereof, the tongues 34 being arranged adjacent the inner end of the slide and the tongues 3S t adjacent the outer end thereof. Each of the tongues 34 and 3-5 incline upwardly and rearwardly or toward the outer end of the slide.

The slide is releasably latched or retained in its outermost Ior bed position or in its innermost or chair position by spring tensioned retractable latching

arms

36 and 37 which are slidably carried by the main frame 1i) and disposed transversely thereof at the outer or rear end thereof. As shown the

arms

36 and 37 iiatwise engage beneath the frame of the cushion 12 and each has a pair of slots 39 into which project guide and retaining pins 40. The

arms

36 and 37 are L-shfaped and interposed between the adjacent ends is a helical coil compression spring 38 normally urging the arms to latching position. The opposite ends of the

arms

36 and 37 project through suitable slots in the frame iti to be arranged inthe path of travel of the

inclined tongues

34 and 35.

When the slide frame 15 is pulled outwardly the

latching arms

36 and 37 are first retracted by pressing the L ends `together to enable the tongue '35 to move past the same and dispose the ends of the arms out of abutting relation. Then the tongue 34 will abut )against the ends of the released arms and prevent further outward movement of the slide frame yl5 on the main frame 10.

yFrom the above description it isv apparent that we have produced an exceedingly simple convertible two seat chair-couch arrangement which can be quickly and easily converted from one use to the other. The compactness of the arrangement lends it for use on boats and other places where space must be conserved. The various parts are sturdily constructed to withstand vibration and shocks incident to use. t

Numerous changes in details on construction, arrangement and operation may be effected without departing from the spirit of the invention especially as defined in the appended claims.
