the floor, the pivots of the truck frame ride up
wardly and vertically in the channel members un
til the legs of the truck member all touch the
floor at once at which time the level of the truck
frame is the same as the level of the single bed
afforded by the stationary frame, thereby afford
ing a double bed.
The single bed of the truck
frame is capable of complete separation from the
stationary frame by lifting the pivots thereof
from the channel members in the end pieces of
the stationary frame.
‘ .
The novelty of the invention resides in the
articulation between the stationary frame and
the truck frame and the manner of supporting
15 the said truck frame when in upright position,
‘the said manner of supporting the truck frame
offset portions extending from the inner surfaces
to cooperate with the slots in the aforementioned
uprights whereby the stationary frame acts as
a suspension from the end pieces. It can easily
be seen, however, that the end pieces H] and II
may be supported on the uprights of the station
ary frame where the said uprights are designed
to be supported on the floor. In this event, the
?ngers projecting from the inner surfaces of
the end pieces l0 and Il would have downwardly 10
projecting offset portions to cooperate with the
slots in the uprights. This invention contem
plates such a variation although the drawings
omit reference thereto.
,
As shown in the drawings, the stationary frame 15
affords a bedding storage compartment by pro
viding a bottom wall 38 extending from the
being equally applicable to the support of the
upright or back of an ordinary couch having an
lower longitudinal rails 20 and 2| and from the
upholstered back with a frame work therefor.
Moreover, novelty of the invention resides in the
other features hereinafter set forth in a speci?c
description of the preferred form of the inven
tion shown in the drawings.
The stationary frame of the convertible couch.
25 is provided with two end pieces I!) and If to
ing from the lower longitudinal rail 20 to below
serve as the arm members of the structure and
may be upholstered in any known manner. The
upper parts of the arm members are designated
by numerals l0’ and II’ respectively. The sta
30 tionary frame is made preferably of angle iron
and is assembled from uprights or legs !2, l3,
l4 and I5, lower end rails l6 and H, upper end
rails l8 and [9, lower longitudinal rails 20 and
2 l, and upper rear longitudinal rail 23 and upper
front longitudinal wire or ?exible band 22, the
said member 22 being extended from the upper
end rails 58 and E!) by means of the ordinary
coil contractile springs. The purpose of having
member 22 ?exible or resilient is to afford a
springable forward edge to the couch. The upper
end rails of the stationary frame designated by
numerals l8 and iii support a bed spring which
is pivotal for the greater part of the width there
of. The bed spring for the pivotal part thereof
45 is provided with a frame member having end
rails 24 and 25 superposing end rails is and I9
respectively and pivoting with the latter rails at
24’ and 25’ respectively. Connecting end rails
24 and 25 is a longitudinal rail member offset
50 downwardly and extending forwardly thereof,
the said longitudinal rail member being desig
nated by numeral 26, and being adapted to clear
member 22 in the raising and lowering thereof.
Beyond pivotal points 24’ and 25' are sections
55 of end’ rails 21 and 28 superposing and connected
with the end portions of end rails I8 and I9
respectively of the stationary frame. End rails
21 and 28, and end rails 24 and 25 of the pivotal
frame member furnish the supports for the usual
60 contractile coil springs 31 which serve to main
tain the known wire or band surface for the
support of a mattress 41, the said wire or band
surface not being shown in the accompanying
drawings.

the wire or band member 22 and from uprights
l2 and E4, and a rear wall 40 extending from
uprights l3 and I5 and from upper and lower
longitudinal rails 2| and 23. The end pieces 10
and H furnish side walls for the bedding storage 25
compartment. The walls mentioned in this para
graph may be of any suitable material such as
cedar wood‘or any other adaptable substance.
In order to gain access to the said, bedding
storage compartment, the pivotal frame, bounded
by end rails 24 and 25 and front or longitudinal
rail member 26 is raised as is! shown in Figure 3
of the accompanying drawings.
Numeral 42 represents any upholstery material
such as cloth and is preferably stretched between 35
the front edges of end pieces l0 and H and is
mounted between lower longitudinal rail 21! and
above wire or band member 22 to give the couch
a ?nished appearance inthis region as seen in
Figure 1 of the accompanying drawings. Numer 40
als 43, 44, 45 and 46 represent supports on which
the stationary portion of. the convertible couch
rests against the floor, 45 and 46 being the known
casters while 43 and 44 are leg sections. Behind
the leg sections 43 and 44 are casters 48 and 49
to enable easy rolling of the couch.- It is easily
seen'that housings maybe provided for the cast
ers 45, 46 and 48 and 43 thereby eliminating leg
sections 43 and 44. and thus rendering an im
proved appearance to the structure.
50
Between end rails l6 and 18 of the stationary
frame is af?xed a vertical frame member 50 pro
vided with a vertically extended slot through
which a pivoted catch arm 5! rides, the said catch
arm being pivoted at 54 to the end rail 24 as
shown in Figure 3 of the accompanying draw
ings. The lower edge of arm 5! is provided with
a notch 52 near the outer extremity of the said
arm which notch ‘is adapted to catch in a cross
member 53 in the slot of frame member 53,‘ Thus, 60
the cross member53 serves as a bearing for the
lower edge of arm 5|; when the pivotal spring
is raised, the same has alimiting and locked
position when notch 52 engages the cross mem
ber 53. Inorder to lower the pivotal spring, arm

'Figure 8‘i's‘ a sectional'view‘ofi an alternate
manner of supporting the back member of the
convertible couch and differs from the described 65
structure in that the channel members 85 and 85'
are lengthened su?iciently to bring the rear lon

pivotal link 83 mounted to end rail 51 by a con
tractile spring 84. Leg 10" is provided with such as a plurality of brackets 91 to hold mat
tress 96 in vertical position above rail 55, a bet
75 similar means.
ter looking top is given to the convertible couch.
2,107,728
At ‘the same time uprights 68, 60’, 59 and band
members 62’ are eliminated to support the back
mattress 96 when in upright position. As shown,
brackets 91 extend from rear wall 40 of the bed
ding storage compartment. It is easily seen that
any other form of a support such as a ledge may
be substituted for brackets 91 to function as a
support for mattress 96 of the rear of the con
vertible couch when the said mattress. is in up
10
right position, the said support being suitably
mounted from either the rear portion of the
stationary frame or from the inner sides of the
end pieces llland ll.
The convertible couch is susceptible of being
15 upholstered in any known fashion, one form of
upholstery being shown. in Figure l of the ac
companying drawings. Mattress 41 of the sta
tionary frame and mattress 96 of the back or
movable frame are fashioned to present the ap
pearance of adjoining cushions.
The conversion of the, couch to a double bed
or to two single beds wherein the members are
separable or are articulately joinedat the option
of the user involves a simple operation that a
child can accomplish. Pairs of folding legs 68’,
25
‘ 68" and 19', 10" are'drawn outwardly into ?nal
open position by pulling the connecting pieces
68 and 10 respectively until the legs impinge
against their respective stops through the action
of the contractile springs already described.
Thereupon ?ngers 88 and 9| are raised to up
right position ‘as. shown in solid lines in Figure 5.
Thus the rear support of the movable frame
when in upright position is removed allowing the
back or movable frame to pivotally drop out
35 wardly by virtue of its own weight. Pivots 86
and 81 supporting and attached to the movable
frame at this time rest on the bottom closed por
tion of slots 85’a and 85a respectively and revolve
thereabout. Pivots 86 and 81 are forced up
40 wardly along the vertical slots 85'a and 85a re
such as tape members extending from the sur
faces of the mattresses to be tied to the springs
at suitable places can be resorted to.‘ Such tem
porary af?xation is especially necessary for mat
tress 96 since the latter is in upright position
when the convertible couch is in non~bed use.
Moreover, the spring surfaces themselves may
be covered with cloth to protect the mattress
thereagainst. The bedding compartment in the
‘stationary frame serves to store the materials
needed for the use of the convertible couch as a
double bed or as two single beds.
In order to reassemble the stationary frame
and the truck or movable frame into a converti
ble couch, pivots 86 and 81 are inserted into slots 15
8571. and 850. respectively, the movable or truck
frame is raisedfrom the ground whereupon the
weight of the said truck frame causes the pivots
86 and 81 to descend to the lowermost wall of
slots 85'a and 8511 respectively. Thereupon the
legs are folded inwardly.
Fingers 86 and 9| are
manually made to engage end rails 51 and 58
respectively of the truck frame to maintain the
latter in upright position.
It is to be clearly understood that minor 25
changes and variations in the structure of the
several parts, in the material and integration
thereof and in the combinations and subcombi
nations thereof may all be resorted to without
departing from the spirit of the invention and 30
Without departing from the scope of the append
ed claim.

I claim:
In a convertible couch, a stationary frame
having a bed spring surface, end pieces to sup
port the said stationary frame, a second frame
having another bed spring surface, foldable up
rights connected to the said second frame and
capable when extended of independently sup
porting the second frame horizontally at a 40
height substantially the same as that of the ?rst
mentioned bed spring surface, pivotal securing
spectively from the time that legs 68" and 19" ‘ means between the stationary and second frames
