structures have heretofore been devised, >such convertible
structures being adapted to be utilized either as beds or
as another »type `of -furniture. rIlhis was accomplished

FIG. l2 is a view similar to FIG. 11 but showing the
device in the open position.
Referring now in greater detail to the various figures
yof the drawings wherein similar reference characters refer
either by simply fitting a fabric `cover `over the bed or by
making the bed collapsible into other forms such as a
sofa, chair or the like.
to similar parts, there is shown in FIG. 1 a convertible
lbed in ‘the 4form of a generally square-shaped ottoman 10.
The ottoman 10 comprises .a cover portion which includes
a cushion 12 from which depends a skirt 14. The cush
ion l2 sits on top of the fully collapsed bed frame which
is supported by casters y16 for easy movement of the de
vice, while ythe skirt 14 encloses and conceals the frame of
the bed. The cushion and skirt may be made of leather,
plastic, textile fabric, etc. and of any desired. color or
However, these prior types of convertible beds were
limited in the choice of size and shape in the collapsed
position so that even in such collapsed position, they still
had to assume the shape of either sofas, divans or large
chairs. This not only often rtook up an undesirably large
amount of room »but also often clashed with the surround~
ing decor. On the other hand, lwhere )attempts ‘were made
to collapse the device into a relatively small space, it was
necessary to either first remove the mattress 4and store it
Instead of the ottoman arrangement of FIG. l, the same

be collapsed with the ibed frame itself.

In addition, prior type converti-ble bed structures were
often insufficiently supported in .the collapsed position so
20 with its sides overhanging a generally square, hollow
body portion 22. The top 20 and tbody portion Z2 may
be made of wood, metal, rigid plastic material or any other
that, if used as a seat, they would tend to sag or buckle
under Ithe weight of the sitter.
It is one object of the present invention to overcome
the above and other disadvantages of the prior types of
convertible beds rby providing a convertible 'bed which is
collapsible from »a full sized, ñrm land steady extended 5
bed position .into a compact folded position wherein the
device may be utilized in various selected lforms in accord
ance with the size, shape and decor of the room.
Another object of the present yinvention is to provide a
convertible ’bed of the aforesaid type which is lirm and '
sturdy .in its various collapsed positions so that it may be
desired material. The body portion 22 is provided with
an open bottom so that it may be placed over or lifted olf
of the fully collapsed bed frame.
The fully collapsed bed is illustrated in FIG. 4, and its
partially collapsed and fully open or extended positions
are illustrated in FIGS. 6 and 7 respectively. The bed
comprises a frame which includes a base section 26, a
front or head section 2.8, a front intermediate section 30,
a rear intermediate section 32 and a rear or foot section
34. The sections 28-34 are illustrated in FIGS. 4, 6 and 7
by the corresponding side bars comprising angle bars
`advantageously used in such positions to etliciently sup
designated respectively as 36, 38, 40 and tubular bar 42
port a person or various other types of objects such as
lamps, vases, etc.
Another object of the present invention is to provide a

provided on the opposite side of the frame and are con
convertible bed of the aforesaid type which incorporates a
unitary mattress which extends .the full length of the bed
when the bed :frame is in extended position and which
easily folds in-to and out of collapsed position along with
the Ábed frame.
Other objects and many of the attendant advantages of
this invention »will be readily appreciated as the same be
comes better understood by reference to the following de
tailed description ywhen considered in connection ywith the
accompanying drawings wherein:

present invention, in fthe fully collapsed position and ar

ing springs 44 having hook ends secured in holes 46 in
the horizontal portions of the respective side bars.
The angle bars 40 on opposite sides of the section 32
are connected by a transverse tubular rod 48 having flat
60 tened ends 50 riveted at 52 to the corresponding bars 40.
Angularly extending between each of the two bars '40
(only one being shown) and the adjacent portion of rod
43 is a brace bar 54 comprising two offset portions sepa
rated by a shoulder 56 and having its ends riveted at 53
65 and 60 to the bar 40 and rod 48 respectively. The brace
rod 48 and brace bars 54 serve as additional strengthen
ing means, especially when the device is in the fully or .
partially folded positions illustrated in FIGS. 4 and 6.
The base section 26 comprises a pair of oppositely ar
ranged angle bars 62 (only one of which is shown) and
each of these angle bars 62 is integral with a front up
standing or vertical angle bar 64. The upper portion of
each bar 64 is provided with an aperture to receive a pivot
pin 66. This pivot pin 66 is received in a corresponding
aperture in the front portion of the corresponding bar 36
of section 28 to provide a pivotal connection between the
base section 26 and front section 28. The base section
itself is supported by the casters 16.

corresponding bar 42 when the bed is in the open position
(as in FIG. 7) to limit the rotational movement of the
leg 106 about pivot 122 to prevent inadvertent collapse of
the leg in its supporting position. Such inadvertent col
lapse is also prevented by the tension on the link 114 be
tween the rivet 112 positioned at the end of the slot 110
'and the pivot pin 118.
