(oi. s-zii This invention relates tol improvements in - studio couches and relates particularly to studio couches of the type embodying two couch sec ' tions one of which is movable relative to the 5 other and one of which is collapsible so as to fit under and be concealed by the other when the use of both sections is not required. The main objects of the invention are to pro vide a studio couch structure of the type indi 10 cated, wherein vthe movable section is freely and easily movable so as to facilitate opening and closing of the structure; to provide such a struc ture wherein the collapsible section may be raised or lowered with the greatest of ease; to provide 15 an arrangement whereby the collapsible section may be caused to automatically adìust itself from lowered or collapsed position to raised or bed position as an incident to extension of the couch; to provide means for eñ‘ectively locking the two 20 sections in relatively extended position; to pro vide means for maintaining the sections in their normal cooperative relation, but which means is readily disengageable to permit separation of the sections for use independently of each other; 25 and in general, it is the object of the invention to provide an improved studio couchstructure of the type indicated. Other objects and advantages of the invention will be understood by reference to the following 30 specification and accompanying drawings (4 sheets), wherein there is illustrated an improved studio couch construction and certain modiñca tions thereof embodying the invention.

Suitable bed bottom fabric in dicated at 22 is stretched within said bed bottom frame and serves to support a suitable mattress or cushion 23. The main couch section may be 35 couch embodying the improved construction and showing the parts in their normal, collapsed or telescoped relation to each other, one of the sec suitably enclosed with wood as indicated at 24, or upholstered in any conventional manner to provide the desired appearance. tions being also shown'in dotted lines in its ex A movable and collapsible or foldable couch section is designated 25, the same being shown in 40 Fig. 1 in its telescoped position within the main section 20. The movable section comprises a main frame 26 of angle iron or other suitable construction which supports bed bottom fabric of any suitable type such as indicated at 21. The 45 main frame of the fold'able section is supported by 4O tended (but not raised) position relative to the other. ` Fig. 2 is a transverse section similar to Fig. 1, but showing the sections in their »extended co a operative bed position. Fig. 3 is a plan section on the line 3-3 of Fig. l, but showing the two couch sections in partially extended relation. Fig. 4 is a sectional illustration approximately 50 'on the line li-li of Fig. 2, but showing the parts in the position they occupy when the collapsible section is folded and telescoped under the other section. Fig. 5 is a section approximately on the line 55 certain parts when the collapsible couch section is in its lowered or collapsed condition. 5-5 of Fig. 4, representing the relationship of pairs of crossed legs at its opposite ends, each pair of crossed legs comprising angle iron members such as 28 and 29 which are pivoted together in termediate their ends as indicated at 30. Suit-_ r50 able brackets may be secured to the respective leg members for receiving the pivot 30 as indi cated in the drawings. The lower ends of the legs 28 and 29 are provided with roller casters 3|, 3l. ' The upper ends of the legs are connected to the 55 2,135,687 2 end of the frame so as to permit folding of the legs to a position closely approximating a coplanar u relation in which the foldable section may be slid or rolled into the space within the main couch sec tion 20. The upper end of the leg 29 is pivoted di rectly as indicated at 32 to the end of the frame 26. The leg 28 is connected to the frame through the agency of a rock arm 33 which is secured 10 at one end to a shaft 34 so as to be rotatable with the shaft. The other end of the rock arm 33 is pivoted as indicated at 35 to the upper end of the leg 28 through the agency of a suit able bracket which is secured to the upper end 15 of the leg as indicated in the drawings. It will be understood that the legs 28 at both ends of the collapsible couch section are con nected to arms such as 33 which are secured to the shaft 34. Hence, when the hand lever 31 is actuated as above described, the legs at Si both ends of the couch will be caused to fold in the manner explained. A helical spring 46 has its opposite ends con nected to upper portions of the legs 23 and 29 through the agency of suitable brackets as in dicated in the drawings. Such springs may be provided at both ends of the couch. The springs 46 are of such length and strength that when the collapsible couch section is in its extended and raised position, they are under only slight The shaft 34 is rotatably mounted in suitable bearing brackets such as indicated at 36, which brackets are suitably secured to the frame ends in proper position as most clearly illustrated in 20 Fig. 7. The various brackets may be attached by riveting, welding, or otherwise, to the legs, frame parts, etc., to which they are rigidly se cured. At one end of the collapsible section (or at 25 both ends if preferred), there is provided a lever mechanism for effecting folding of the legs for the purpose of collapsing the couch. The said lever arrangement is best illustrated in Fig. '1, and also appears in Figs. l, 2 and 3. Said lever 30 mechanism includes a hand lever 31 which is pivoted as indicated at 38 to the outside of the end member of the main frame 2B, the pivot 38 being located intermediate the ends of the lever. A guard member 39 overlaps the hand lever 35 and is mounted on the end member of the main frame 26 in properly spaced relation thereto so as to permit the hand lever to be rocked between the frame end and said guard member. Said guard member may be maintained in spaced re 40 lation adjacent its ends by means of spacers 40, 40, as indicated in Fig. 3. The lower end of the hand lever 31 is con nected by means of a link 4l to the rock arm 33, the said link being pivoted as indicated at 42 to the rock arm 33 and as indicated at 43, to the lower end of the hand lever 31. The rock arm 33 is provided with a stop pin 44 which is adapted to engage a shoulder 45 provided on the bracket 36 to limit the rocking movement of 50 the rock arm 33 in the leg unfolding direction. The said stop means serves to determine the ex tent of unfolding movement of the legs and hence the extent of elevation of the main frame of 55 the collapsible member. By inspection of Fig. 2, it will be observed that the centers of the pivots 34, 42 and 43 are not in alignment so that upon upward and outward swinging movement of the upper end of the hand lever 31, the rock arm 33 may be caused to swing 60 in a counterclockwise direction about the axis of the shaft 34. Such swinging movement of the rock arm 33 will, of course, effect relative folding movement of the legs 28 and 29 and the parts are so designed that the folding move 65 ment will be carried on until the legs and frame 26 reach the position indicated -in Fig. 1. Any suitable stop means may be provided for stop ping the folding movement of the legs at the point indicated in Fig. l, and in this instance 70 the stop is effected by engagement of the upper end portion of the leg 23 with the shaft 34 as clearly shown in Fig. 1. The upper end of the leg is illustrated as having been recessed to re ceive the shaft and to thereby permit the` de 75 sired folding movement. or no tension. Hence the springs do not ini tially offer material resistance to the lowering movement of the section as initiated by opera tion of the hand lever 31. It will be noted that the pivoted crossed leg 20 arrangement described, has a normal tendency to be self-folding so as to effect collapsing of the couch. Self-folding is, however., adequately prevented by the described arrangement since there is sufficient upward thrust in the leg 28 to prevent downward swinging movement of the upper end of the leg about the axis of the shaft 34, notwithstanding the said normal tendency to effect self-folding movement. Also, when the foldable couch section is occupied by a person, 30 the added weight thereon amplii'les the locking effect of the described arrangement. In effecting lowering or folding of the col lapsible couch section, the handle 31 is swung upwardly and outwardly until the direction of the thrusts which control the folding movement are changed so that the thrust which tends to effect self-folding overcomes the thrusts which tend to effect locking in raised position where upon the couch gently lowers itself. The springs 40 46, of course, serve to cushion the lowering move ment so as to avoid jars and shocks. Merely for purposes of explanation and without attempting to indicate with exactness, it may be said that the self-folding movement may commence when the centers of the pivots 34, 35 and 36 are in alignment. Hence it will appear that the extent of folding movement which must be initiated through the agency of the hand lever 31 is only a relatively small portion of the entire folding - movement. A mattress or other suitable cushion 41 is supported on the bed spring structure 21 of the collapsible section and a suitable finishing ele ment 48 is secured to the front side member of the collapsible section main frame 26. The fin ishing member 48 may be in the form of a wood panel having its front face finished or uphol stered to match the finish of the stationary sec tion, _and said element 48 may be suitably shaped so as to provide representations of legs indicated at 46 at its ends. However, the legs are not required for supporting'the structure, the same being adequately supported by its caster en (i5 gagement with the floor. The stationary and movable couch sections are preferably connected by means of a device which will serve to maintain the two sections in predetermined spaced relation during the rela tive horizontal movement therebetween, thereby 70 to facilitate withdrawal or telescoping of the collapsible section relative to the stationary sec tion. In this instance, the device just referred to is also arranged to lock the movable and sta tionary sections in predetermined spaced relation 75 2,135,6,87 3 'when the collapsible section is elevated to '_bed ` where they are connected. Hence, a supporting position, the device being also such that it may caster .61 is secured to the lowermost member 50 be readily disconnected to permit complete sep in axially aligned arrangement to the, pivot con aration ofthe two couch sections for independent nection 52 between the lazyL tong members. As indicated in Fig. 2, when the couch structure is The connecting device just referred to consists opened up, the lazy tong members assume a in this instance of a pair of elongated, generally slightly sagged position which is limited by the longitudinally extending crossed bars 50 and 5I', caster 61 so as to maintain free working` of the the same being pivoted together intermediate lazy tong device. 10 their ends as indicated at 52. The crossed mem- . When the collapsible couch section is in its bers 50, 5I constitute a simple lazy tong device folded and telescoped condition as shown in Fig. use. ' which has one pair of ends pivoted respectively as indicated at 53 and 54 to the stationary and movable sections respectively. The other pair of 15 ends of the lazy tong device are connected re spectively to the movable and stationary couch . sections so as to be pivotally and slidably mov-- able longitudinally of the respective sections. As best shown in Fig. 3, the end 55 of the lazy tong 20 device is provided with a pin 56y which is adapt ed to move longitudinally of the stationary sec tion in a slot 51 provided in a frame element 58 'of the stationary section. The frame element 58 is suitably secured rigidly toA frame portions 25 2| of the stationary section and the pivotal con nection 53 of the lazy tong member 50 is made »to said member 58. .The end 59 of the lazy tong member is similarly connected to a tie bar 60 of the movable couch section, said connection com 30 prising a pin 6i carried by the end portion „59 of the lazy tong and a slot 62 in the tie bar 60. The tie bar 5l! extends longitudinally of the collapsi ble .couch section and is rigidly secured at its opposite ends to the lower end portions of the legs 29. The tie bar B0' serves to maintain the lower ends of the legs 29 at opposite ends of the couch in properly spaced relation.l The leg struc ture of the collapsible section is` further rein forced by means of a longitudinally extending tie bar 53 which is located in this instance slightly above the pivotal connection 30 between the crossed legs, said tie bar being riveted or other wise rigidly secured at its ends to the legs 28 at each end of the couch section. The reinforcing structure also includes a crossed pair of straps 64 and S5 which are riveted as indicated at 66 to the tie bar 63 and riveted or otherwise rigidly connected at their ends to the opposite legs 28. 1, the pin 6I (see Figs. 2 and 3) is disposed ap proximately in a yertical position, depending from lthe lazy tong end 59 through the slot 62 in the t'e bar 60. The tie bar 60, as best shown in Fig. 1, assumes a position in which its flanges are in clined somewhat to the horizontal and vertical. When the foldablc couch section is extended and raised to its bed position as indicated in Fig. 2, the angle iron tie bar 60 assumes an oppositely inclined angular relation to the horizontal and vertical. The pin 6i, however, remains in a sub stantially vertical position since the lazy tong device is not materially elevated at its outer end incident to the unfolding of the collapsible sec tion. The shifting angular position of the tie bar 60 is herein utilized to provide a lock for prevent ing horizontal sidewise movement of the collapsi ble section after the section is raised to its bed position. Such lock is obtained by securing a 30 pin 68 to the depending side flange of the tie bar ‘60, said pin projecting inwardly substantially in parallel relation to the top `ñange of the tie bar from a point approximately midway of the width of the said depending flange. When the foldable couch section is in its lowered or col lapsed condition, the pin 68 will assume a posi tion clear of the path of movement of the pin 6| of the lazy tong device, as best shown in Fig. 5. When the couch section is unfolded or elevated 40 to bed position, the pin 58 will assume a position in the path of movement of said pin 6i substan t‘ally as illustrated in Figs. 4 and 6. As shown in Fig. 4, the pin 68 is so located that it will lock the lazy tong pin 6I in its position at the inner 45 end of the slot 62, whch is its position only when the couch section is fully extended. The locking means thus described is entirely automatic in its It will be apparent that the reinforcing structure ' operation, is exceptionally simple and durable 50 just described serves to very rigidly maintain the leg structure against shifting or angular distor tion in the direction of the length of the couch structure. When the couch structure is collapsed and tele 55 scoped to the condition illustrated in Fig. l, the members 5G and 5l of the ‘lazy tong device as in construction, and very eñ‘icient for its indi cated purpose. The connection between the end portion 59 of the lazy tong device and the tie bar 6U of the movable couch section may obviously be readily disengaged by simply lifting the said end por tion of the lazy tong device to remove the pin 6l sume a closed position wherein the ends of the from the slot 62. The pivotal connection be members 5l! and 5I are disposed quite close to ‘ tween the opposite end of the lazy tong device each other as indicated in Fig. l. When the col and the movable couch/section also embodies a 60 lapsible section 25 is .pulled out, the lazy tong 59 thereofv sliding longitudinally inwardly of the pivot pin 5t (see Fig. 4) which may readily be 60 removed from an aperture in the top flange of the member of the tie bar 60. Hence when it respective couch sections as an incident to the is desired to use the two couch sections inde outward movement of the movable section. The pendently of each other, they may be readily disconnected by merely lifting up the two outer ends of the lazy tong device to disengage them from the tie bar 6U of the movable section. Then device is unfolded or opens up, the ends 55 and lazy tong device serves to maintain a parallel pre determined spaced relation between the two couch sections so as to avoid any tendency of the movable section to assume an angular rela tion to the stationary section wherein it might become bound to the stationary section with re sulting diiiìculty in completing the withdrawal movement. Because of the considerable length of the lazy tong members Eiland 5l, which may be made of relatively thin metal straps,'they 75 have a tendency to sag intermediate their ends the lazy tong device may be manually pushed back under the stationary couch section where it is out of the way and substantially concealed. Reconnection of the two couch sections requires merely a reversal of the disconnecting operation which, as indicated, is -exceptionally simple, re quiring no particular skill,4 strength or tools` When the movable »couch section is .withdrawn 2,135,687 4 position illustrated in Fig. 11, and preferably to the position indicated in dotted lines in Fig. 1, slightly prior thereto. As soon as the lower end of the pawl 69 is raised above the upper end of it may be raised by applying a slight lifting force to any point around the periphery of the collapsi ble section. the stud 14, the spring 1I pulls the pawl to its It is merely necessary to initiate the ' free position as illustrated in Fig. 11. upward movement, whereupon the springs 46 will complete it. It is of course apparent that the springs 46 are under great tension when they are stretched as required in the folded position of the couch as illustrated in Fig. 1, so that they exert 10 a material force tending to raise _the couch sec tion. However, the springs are s'elected so that the tension thereof when fully stretched is not quite sufficient to effect raising movement unless assisted to the extent of initiating the upward by be swung against the tension of the spring 1I to a higher position than that illustrated in Fig. 10 l11. When the movable section is telescoped into the stationary section, the stud 14 rides outwardly un‘der the bottom of the pawl 69 until it passes 15 movement manually as described, or otherwise. If desired, means may be provided for initiat ing the raising movement of the collapsible sec tion as an incident to the withdrawal thereof from the stationary section. For this purpose a 20 pawl such as indicated at 69 may be pivoted as indicated at 10 (see Figs. 10 to 13 inclusive). Said pawl acts downwardly against lazy tongs element 59 to exert an upward thrust and in this instance comprises a short length of angle iron having a vertically disposed flange disposed adjacent the 25 depending flange of the main frame member 26 and a horizontally extending flange extending in wardly from the lower edge of the vertical flange. Spring 1|, stretched between a bracket or suitable 30 anchorage carried by the main frame 26 and a headed pin 12 or the like carried by the pawl, serves to normally urge the pawl to swing up wardly toward a position of parallelism with the main frame. The lower or free end 13 of the 35 pawl is adapted to be engaged by a stud br other abutment 14 which is carried by the end portion 59 of the lazy tong device. The stud 14 is so located on the end portion 59 of the lazy tong de vice that it will engage the free end 13 of the pawl 40 slightly prior to the moment that the movable couch section reaches its fully withdrawn posi tion relative to the stationary section. During the subsequent movement of the movable section to its fully withdrawn position, the inward move ment of the stud 14 acts against the lower end of 45 the pawl 69 to force said end inwardly, whereby the pawl acts as a shifting thrust rod and trans mits the movement of the stud 14 into upward movement of the main frame 26. Since it is necessary to apply only sufficient force to initiate 50 upward movement of the main frame 26, it will be apparent that the extent of longitudinal move ment required of the stud 14 to initiate said up ward movement is relatively small as compared with the total length of longitudinal movement 25 of the stud. In Fig. 12 of the drawings, the structure is illustrated in its collapsed condition with the stud 14 shown in full lines in its corre sponding outermost position. In dotted lines, the 60 stud 14 is shown in the position which it- assumes when it first engages the free end of the pawl 69. In Fig. 1l, the stud 14 is shown approximately in its innermost position. 'I'he pawl `69 and main 65 frame 26 are shown in dotted lines in the posi tion which they would assume relative to the stud 14 if the springs 46 did not act on the struc ture to complete the raising movement. Whether 70 - When the collapsible section is lowered or folded, the free end 13 of the pawl 69 .will engage the top end of the stud 14. The pawl will there or not such position occurs as an actual fact is diilicult to determine because the springs 46 ex ert a raising force at all times and actual raising movement resulting from the spring force may begin before the stud 14 reaches the position illus trated in Fig. 11. In all cases, the springs 46 are designed to start the raising movement of the 75 main frame by the time the stud 14 reaches the the end thereof, whereupon the pawl drops slightly until its free end rests on the top of the 15 end portion 59 of the lazy tong device. The ar rangement _is preferably such that during the time that the collapsible couch section is folded and telescoped, the pawl will always rest on the top surface of said end portion. Hence the parts 20 will always be in operative relation. In Figs. 1, 2, and 3, the arrangement is shown as embodying a horizontally movable and foldable couch section which is adapted to be received within the space under the main stationary couch 25 section. In Figs. 8 and 9, the application of the structure herein explained is illustrated as being embodied in an arrangement where the collapsi ble couch section is normally stationary in respect of horizontal movement, the non-collapsible sec 30 tion being `in this case horizontally movable. In this arrangement, the leg 28 is shown as embodying the caster 3i, but the leg 29 is pro vided with an anti-friction tip 15 of rubber -or the like which will have a definite tendency to prevent 35 horizontal shifting of the foldable couch section. The provision of the anti-friction tips 15 on the two legs 29 at the ends of the couch serves, of course, to determine the position of the foldable couch section. The casters 3| on the lower ends 40 of the legs 28 permit free movement of the lower ends of said legs across the floor as is required in the 'collapsing or folding of the foldable couch section. Fig. 8 illustrates the movable non-co1 lapsible or main couch section in its position tele 45 scopcd over the stationary but foldable section, the movable section being designated 16 and the foldable section being designated 11. In other details of construction the sections 16 and 11 may be substantially the same as the structure de 50 scribed in connection with Figs. 1, 2 and 3. In Figs. 10 to 13 inclusive, the automatic raising mechanism is illustrated as being applied to a couch embodying a non-foldable but movable main section such as illustrated in Figs. 8 and 9. 55 The details of construction and arrangement of the automatic raising mechanism as illustrated in Figs. 10 to 13 apply without material modification to the arrangement illustrated in Figs. 1 to 3. The structure and arrangements herein de 60 scribed result in an unusually easy operating studio couch. It involves no critical adjustments or operations so that no difficulty is experienced in extending the couch to form a full-sized double bed, or in separating the two couch units to pro 65 vide relatively independent single beds or in col lapsing the one section and telescoping the two to confine both sections to the space normally occu pied by a single couch. , 70 rangement may be made without departing from the spirit of the invention, the scope of which should be determined by reference to the follow ing claims, the same being construed as broadly 75 as possible consistent with the state of the art.
