4 Claims.
This invention relates to convertible lounges
adapted to be used as a bed or a couch.
The primary object of the invention is to pro
vide an extremely simple convertible bed which,
when changed to a couch, will automatically
incline the seat portion backwardly and down
wardly so as to be more comfortable. When
converted to a bed, the bed spring is brought y
to horizontal position and the pillow supporting
the back bar is swung forwardly out of the way.
A further object of the invention is to provide
a strong and durable mounting for the pivotal
legs which are operated automatically by a con
nection with the back bar.
The invention is illustrated in a preferred
embodiment in the accompanying drawings, in
Figure 1 is a plan view of the bed frame and
mechanism with the box spring and mattress
removed; Fig. 2, an end elevational view of the
device in bed position; and Fig. 3, an end eleva

(Cl. 5-5-9)
It Will be understood that in sitting position
the bar is turned up to the position indicated
in Fig. 3, and will support pillows, indicated
at 22, when the device is used as a seat.
In this
position the back bar rests against the stops' I6
and the legs I I are swung back so as to lower the
rear portion of the bed frame.
The plate 'I
restrains the legs against longitudinal movement
with respect to the bed frame, and rearward
movement of the legs is limited by the slots '9
and the stops IB. To transform the couch to a
bed, it is merely necessary to swing the bar I'I
forwardly to the floor, as indicated in Fig. 2.
The foregoing detailed description is given for
clearness of understanding only, and no unneces
sary limitations should be understood therefrom,
for some modifications will be obvious to those
skilled in the art.
