9 Claims.
This invention relates to couch beds in general
and more especially to combination single and
double beds.
Among the objects of the present invention, it is
5 aimed to provide an improved combination single
and double bed consisting of a ?xed main frame,
a movable secondary frame operatively connected
to said main frame to be moved under said main
frame into single bed formation and to be moved
10 to one side of said main frame for double bed
formation, and an extension bed section remov
ably connected to said secondary frame to coop
erate with said main frame to form a double bed
when disposed adjacent to said main frame and
15 to form a separable bed, in which latter case the
secondary frame constitutes a convenient means
for anchoring the extension bed in concealed
position under said main frame when not in use.
It is still another object of the present in
20 vention to provide an improved combination
Single and double bed consisting of a ?xed main
bed section, an auxiliary bed section, a frame
operatively connected to said main bed section
when disposed in extended position to remov
25 ably anchor said auxiliary bed section adjacent
to said main bed section in double bed formation
and when housed under said main bed section
adapted to anchor said auxiliary bed section in
housed position under said main bed section.
30
It is still another object of the present inven
tion to provide an improved means for operatively
connecting to a main bed section a carriage or
frame adapted to anchor an auxiliary bed sec
tion in housed position under said main bed sec
35 tion or in double bed formation adjacent to said
main bed section, which connecting means func
tion properly to guide the carriage and auxiliary
bed section into and out of said main bed section.
It is still another object of the present inven
40 tion to provide an improved actuating means for
catapulting or projecting to one side of a main
bed section an auxiliary bed section normally
housed within said main bed section.
It is still another object of the present inven
45 tion to provide an improved connecting means for
removably connecting the auxiliary bed section to
a carriage which is operatively connected to a
main bed section to be moved into and out of
the same, which connecting means are not only
50
simple in construction but in addition can be
produced at low cost.
These and other features, capabilities and ad
vantages of the invention will appear from the
55 subjoined detail description of one speci?c em

In the embodiment‘illustrated, there is pro
vided a main bed section I, which in the present
instance also constitutes the main frame, and a 15
removable bed section or extension bed section
2 which may be moved into and out of said main
bed section I.
The main bed section I preferably is provided
withfour standards or vertically extending angle 20
irons 3 which are connected to the corners of the
rectangular metal frame 4 which is preferably
provided with a wire support 5 and coil springs 6
forming the inner springs of a'built-in mattress l
for the .main bed section. I.
'
25
The rectangular frame 4 preferably as illus
trated inFig. 3, has along its outer longitudinal
edge a bar 8 cooperating with'the mattress ‘I to
extend beyond the outer side of the frame 4. On
the other hand, the end boards 9 of the main 30
frame I, see particularly Fig. I, extend beyond
the outer faces of the corner standards 4 so that
their front ends are in alinement with the upper
face of the mattress ‘I.
In single bed formation or couch formation, 35
there is loosely laid or separably laid on the
mattress ‘I, a second mattress l0 which mattress
in double bed formation is removed from the
mattress ‘I and laid on the auxiliary bed section
2, as indicated in Fig. 3.
40
The main bed section preferably has small or
namental feet ll formed at the bottom of the
standards 3 as indicated in Fig. 1 which however
are preferably not provided with rollers to form
a substantial anchor with the floor and thus 00- 45
operate with the parts of the couch bed now to
be descried.
The auxiliary bed section 2 preferably has a
longitudinal frame l2, the outer edge of. which is
provided with a front board l3 having at its ends 50
the vertically extending angle irons I4 provided
with bearingsat their lower ends for the large
rollers Ma.
Preferably also adjacent to the rear side of

tially of a pair ‘of connecting links, to wit ‘the‘two
long links 28 and 23 and the two short links '30
and BI resj'iectively.v ‘ One of the links ‘29 is
pivotally ‘connected to the portion 21 of the bar
22 spaced about one-third of the length of the
bar 22 from one end thereof and one end of the
link 3| is pivotally connected to the portion '2'! of
the bar 22 spaced about one-third ‘of the length
of the bar 22 from the other end of the same and
35 the other end of the link 29 is pivotallyconnected
to the front end of the link 30 while the other
end of the link 3| ‘is pivotally 'conne‘cted'toithe
link 28. The links 28 and'29 are pivotally con
nected'to one another at a point which is spaced
about one-fourth of the length of th'elink 28
'from‘its connection with the link 3| and ‘which
is spaced about one-fourth of the length of the
link 29 from its connection withfthe link ‘30.
' The rear end of'the link28 is 'pivotally con

'
In order automatically to eject the carriage 23
when the pedals 44 are so depressed, there is
provided a spring 45 which connects'the link 30
with the endof the abutment 46 extending from 25
the horizontal portion 32 of the" angle iron 33.
This spring 45 is of course heavy enough to per
form the work required of it. It has been found
in practice that a spring of the dimensions indi
cated in the drawings as compared to the'struc .30
ture illustrated is 'su?icient to eject not only the
carriage 23 but also the carriage 23 with the bed
section I attached thereto as illustrated'i'n Fig. 2.
:From the foregoing, it will appear that the '
spring 45 andlinks 28, 29, 30 and 3| will co
operate to eject the carriage 23 when the arm
35 is depressed as above described by the ‘actua
tion of either the lever 4| 'or' the lever 42.
It will also appear that when the carriage 23
is moved into the ‘bed section | with or without
the bed section 2, that after the arm 35 engages
the"~bar,22 'of the carriage 23, it will anchor the
same against ejection by the spring'r45 until the

From the foregoing, it will thus appear that
10 the present invention contemplates an improved
combination single and double bed which in
cludes a twin bed arrangement in which the aux

I claim:
1
l. A main bed section having a chamber, a car
riage, links for operatively connecting the car t10
riage inside of said main bed section to move
into and out of said chamber, an auxiliary bed
section, rollers on which said auxiliary bed sec
tion and carriage are mounted to facilitate mov
ing the same along the floor relative to said main 15
bed section as. an anchor, said carriage having
a longitudinally extending bar having recesses
‘formed along its upper edge, studs on said auxili
ary bed section adapted to rest in said recesses,
and heads on said studs to engage the side of ~20
said bar to form an abutment for carrying the
choring the auxiliary bed section to the main bed
auxiliary bed section with said carriage during
section in double bed formation as well as in
movement thereof.
couch formation.
It will also appear from the foregoing that
the links 28, 29, 30 and 3| cooperate not only
to guide and control the position of the carriage
23 and therewith of the auxiliary bed section 2
relative to the main bed section I but that it also
cooperates with the spring 45 to eject the car
riage 23 automatically when the locking mech
anism is actuated and that it also cooperates to
position the carriage 23 to be automatically an
chored by the head 3‘! of the locking mechanism.
To facilitate smooth operation of the carriage
23 and auxiliary bed section 2 during ejection or
return movement, the position of the rollers i8
is such that they will not engage the floor but
only the rollers 25 and of course the rollers Me.
On the other hand, when the auxiliary bed sec
tion 2 is separated from the carriage 23, the
auxiliary bed section 2 will be supported on the
rollers l8 and Me, the rollers l8 thus merely
serving as auxiliary rollers to cooperate with the
rollers Illa when the auxiliary bed section 2 is
separated from the carriage 23. In operation,
assuming the bed section 2 to be inside the bed
section l and that the shoulder 39 of the latch
head 31 engages the bar 22 to anchor the carriage
and therewith the bed section 2 in single bed
formation, it will only be necessary to depress
one of the pedals 44 in turn to depress the latch
head 31 out of engagement with the bar 22 when
the spring 45 will be free to eject the carriage
23 and therewith the movable bed section 2. In
its outward movement, the levers 28, 30, 29 and
3| will then open in turn to cause the pairs of
bars 52, 48 to move into their extended position,
that shown in Fig. 3, where the bed section 2 will
60 be disposed adjacent the bed section I in double
bed formation. The position of the bed section
2 will be determined by the buffers 54 engaging
the ?anges 41.
In this extended position of the bed section 2,
65 it will of course be a simple matter to raise the
bed section 2 and therewith its studs 19 out of
engagement with the recesses 2! entirely to sep
arate the bed section 2 from the bed section I.
On the other hand, after the bed section 2
70 has been connected to the carriage 23 by the
positioning of the studs 19 in the recesses 2|, it
will only be necessary thereupon when it is de
sired to actuate the bed section 2 into single bed
formation inside the bed section I to move the
75 bed section 2 into the chamber formed in bed
