3 Claims.
My invention relates to an article of furni
ture known as a studio couch.
Such an article
comprises two laterally telescoping sections
which, when telescoped together, form a sofa
or similar article,» but‘ which can be extended to
form a bed-like structure.
My invention relates particularly to the means
employed for locking the two sections of the
studio couch in telescoped relation, and it-is
10 my object to produce a locking means: which
will be simple in construction and which will op
erate positively at all times. A further object
of‘ my invention is to produce a locking mech
anism which, while concealed, has an operating
15 member that will be readily accessible when it is
desired to separate the two sections of the couch.
(C1. 5-55)
upper sectionrof the couch hasv a frame including
front and rear side members I3 and I4, and is
supported on rollers.
The rear side member M
of the upper section is located above the lower
couch~section so that it will not interfere with 5
movement of the upper section when it is with
drawn from the position illustrated in Fig. 1 to
the position illustrated in Fig. 2. The front side
member 13 of the upper section extends down
wardly well below the top of the lower couch 1O
section' to conceal the front thereof.
The front side member II of the lower section
is conveniently L-shaped in cross section and is
a pair of spaced latch members adapted toene
disposed with one'?ange of the L extending
downwardly. The latch mechanism is mounted 15
on the inner face of the side member 13 of the
upper section, and co-operates with the vertical
?ange of the member i I to hold the two sections
together when desired.
The latch mechanism includes two latch mem
bers 15 each of which is L-shaped in horizontal N) 0
plan and has one leg i6 disposed parallel to
gage this ?ange. The latch members are
pivoted on parallel axes and are interconnected
other leg I‘! extendinglrearwardly. The latch
In carrying out my invention, I provide along
the front edge of the lower or normally sta
tionary couch-section an angle iron frame-mem~
her with a downwardly extending ?ange, and
on the upper or movable couch-section I mount
25 by a link which extends horizontally along the
inner face of the front of the frame of the mov
' able couch-section but which is spaced from such
front in order that it maybe engaged at any
point along its length by the hand of the op
erator. The link referred to is pivotally cone
nected to- each of the latch members at a point
such that its weight will tend to‘ cause the latch
members to swing into locking‘ position; and
preferably the link extends through slots in the
35 latch members to limit the extent to which they
can swing about their respective pivotal axes.
The accompanying drawing illustrates my in
vention: Fig. 1 is an end elevation of a. studio
the inner face of the side member 13 and the
members are pivotally mounted with respect to
the side member 13 as by being secured through
the means of pivot pins 18 to attachment plates
H3. The pins 18 are spaced fromv the respective
legs I1’ and extend through the legs 16 near the
top‘ thereof and into the attachment plates which
in turn are secured against the inner face of the
member l3 by screws 20.
The leg I‘! of each latch member is provided
with an upwardly opening notch 25 of a width
somewhat greater than the thickness of the ver- 3
tical flange of the side member‘ H on the sta
tionary couch-section. Beyond the notch 2|, the
upper portion of each leg I1 is cut away to form
couch with the two sections telescoped together

terclockwise direction from the position illus
trated in Figs. 3 and 4, such movement being
limited by engagement of the bottom of each
notch 2| with the side member II to maintain
the latch members in the position illustrated in
Figs. 3 and 5 and in full-lines in Fig. 4. By mov
ing the link 30 to the left in Figs. 3 and 4, how
ever, the latch members can be swung into the
position illustrated in Fig. 6 and in dotted-lines
in Fig. 4, this movement of the latch members
causing the nose of each to swing below the lower
edge of the vertical flange on the member H,
whereupon the two couch-sections may be sepa
rated. In thus releasing the latch members, the
link 39 may be grasped at any point in its length;
and, to make it easier to grasp, the intermediate
portion of the link 30 is conveniently offset out
wardly from the inner face of the side member
l3 on the movable couch-section.
Swinging movement of both latch members is
limited by engagement of the link 30 with the
ends of the slots 32. When the two couch-sec
tions are separated, the link 30 is engaged by the
lower ends of the notches 32 to hold the latch
members in upright position. At the limit of the
releasing movement, the link 30 is engaged by
the upper ends of the slots 32, as is clear from
Fig. 4.
When the two sections of the couch are moved
together with the latch members held in upright
position as above set forth, the inclined cam-sur
faces 23 engage the bottom edge of the member
II and cause the latch members to swing in a
clockwise direction to permit the noses 22 to pass
beneath the member ll.
Telescoping movement
of the two couch-sections is limited by engage
ment of the member H with the inner walls of
the notches 2| which, as is clear from Fig. 6,
are long enough for that purpose. When the
40 side member ll engages the rear walls of the
notches 2 l, the noses 22 will have cleared the side
members, and the force of gravity acting on the
links 3-!) causes the latch members to swing from
the dotted-line to the full-line position shown in
45
Fig. 4, whereupon the notches 2| will receive the
member H and hold the two couch-sections in
telescoped relation.
I claim as my invention:
1. Latch mechanism for securing together the
50 two sections of a studio couch, comprising two
latch members each of a general L-shape in
cross-section, said latch members being pivotally
mounted on parallel axes in longitudinally spaced
relation on one of said couch-sections with two
of their corresponding legs substantially co
planar and the other two legs having provisions
for engaging a part on the other couch-section,
and a link pivotally secured to the co-planar legs
of said latch members and extending through
slots in the other legs thereof, to interconnect
said latch members for joint movement into and
out of operative position, the points of pivotal at
tachment of said link to said latch members be 10
ing so disposed that the weight of said link tends
to swing the latch members to operative position
and said slot being of such length that it limits
such swinging of the latch members.
2. Latch mechanism for securing together the 15
two sections of a studio couch, comprising two
latch members mounted in longitudinally spaced
relation on one of said sections and engageable
with a part on the other section, and common
means for operating said latch members, said 20
means including a connecting member having
its opposite ends connected to said latch members
and accessible to the hand of an operator
throughout substantially its entire length, said
latch members being pivotally mounted on par
allel axes on the associated couch-section, said
connecting member being a link pivotally con
nected to said latch members on axes parallel to
their axes of pivotal mounting, and means on at
least one of said latch members co-operating with
said link for limiting swinging movement of the
latch members under the in?uence of the force
of gravity acting on said link.
3. Latch mechanism for securing together the
two sections of a studio couch, comprising two 35
latch members mounted in longitudinally spaced
relation on one of said sections and engageable
with a part on the other section, and common
means for operating said latch members, said
means including a connecting member having its 40
opposite ends connected to said latch members
and accessible to the hand of an operator
throughout substantially its entire length, said
latch members being pivotally mounted on par
allel axes on the associated couch-section, said 45
connecting member being a link pivotally con
nected to said latch members on axes parallel to
their axes of pivotal mounting, and means on at
least one of said latch members for limiting
swinging movement of the latch members under 50
the influence of the force of gravity acting on
said link.
