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.

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

'
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

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

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

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

sulting diiiìculty in completing the withdrawal
movement. Because of the considerable length

be made of relatively thin metal straps,'they

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

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.
