COLLAPSIBLE BED
Ben McKeithanv Graham, Tupelo, Miss.
Application August 7, 1935, Serial No. 35,176
2 Claims.
The invention relates to a bed and more
especially to a collapsible or extensible bed.
The primary object of the invention is the pro
vision of a bed of this character, wherein the
5 same when collapsed will be concealed within a
cabinet, the latter functioning as a dresser or
other article of furniture and thus the collapsing
of the bed affords space within an enclosure and
such bed will have disappeared, the operation of
10 the bed being simple and assures easy control
in the extending or collapsing of the same.
Another object of the invention is the pro
vision of a bed of this character, wherein on the
collapsing thereof the mattress carried thereby
15 will be automatically folded into compact form
and the latter with the bed will be concealed
within a cabinet or the like, the bed being of
novel construction.
_
A further object of the invention is the provision
(C1. 5—2)
drawer being manipulated from the front of the
latter.
Adapted to occupy the space H within the
cabinet A is the collapsible bed which comprises
a foot section or board l 2 having connection with , 01
lazy tongs B, these being at opposite sides of a
canvas mattress support l3 and each lazy tong
includes the crossed levers I 4 pivoted at their
crossing points as at l5 while the levers at their
meeting ends are pivoted together at l6, these .10
being in the form of rods and underlie the ‘sup
port l3 at a distance considerably below the same.
The tongs B at one end have the sliding con
nections at I‘! with the sides of the cabinet A
inwardly of the space I I therein and likewise these _15
tongs B at the other end through linkage l3
and I9 have pivotal connection at ll’ with the
foot section or board l2 at the brackets 20
thereon.
'
2“ of a bed of this character, which is comparatively
The support l3 through the instrumentality of 20
simple in construction, thoroughly reliable and
effective in its operation, strong, durable, readily
and easily handled, assuring compactness when
the end springs 2| connected therewith and with
the pivot I1 and to a cross piece ?xed to and
between the brackets 20, respectively. is sustained
under tension when the bed is extended while
supplementing the support [3 are spring ten- 25
in collapsed condition and inexpensive to manu
25 facture.
With these and other objects in view, the inven
tion consists in the features of construction, com
bination and arrangement of parts as will be here
inafter more fully described, illustrated in the ac
30 companying drawings, which disclose the pre
ferred embodiment of the invention and pointed
out in the claims hereunto appended.
In the accompanying drawings:
_
Figure 1 is a vertical sectional view through
39 a cabinet showing the bed constructed in ac
cordance with the invention a part thereof and
extended.
Figure 2 is a fragmentary side elevation show
ing the bed partly folded.
40
Figure 3 is a sectional view on the line 3-3 of
Figure 2 looking in the direction of the arrows.
Figure 4 is a vertical sectional View through
the cabinet showing the bed collapsed or folded.
Figure 5 is a front elevation thereof.
Figure 6 is a bottom plan view of the bed when
extended.
Similar reference characters indicate corre
sponding parts throughout the several views in
50 the drawings.
Referring to the drawings in detail, A desig
nates generally a cabinet having at the top there
of a drawer l3 while provided in this cabinet
below the said drawer is a compartment I l which
55 opens through the front of the said cabinet, the
sioned straps 22, these underlying the said sup
port l3 and have connection with the lazy tongs
‘B, the tensioning of said straps 22 being lateral
so that the support [3 will be prevented from
sagging on the extending of the bed.
30
When the bed has been collapsed by pushing
inwardly upon the section I 2, it will be concealed
within the space H in the cabinet A.
Associated with the end ‘portions of the lazy
tongs B are lifter levers 23 and 24, respectively,
the latter carrying connections I‘! while the le
vers 23 are swingingly connected to the outer
most pivot [5 of said tongs. The levers 24, each
by the connection I? slides in a curved slotted
track 25, there being two of these ?xed to oppo- 40
site sides of the cabinet and a link 25 pivoted
to said lever 24 and at 21 to the extension 28
of one of the levers I 4 while the levers 23 each
is pivoted at 30 to a link 3| pivoted at 32 to an
extension 33 of another of said levers l4. These 45
levers 23 and 24, which are in pairs, each car
ries at the inner ends a coiled tensioneol lifter
strap 34 which is disposed transversely of a mat
tress 35 when upon the support l3 so as to be
disposed between the latter and said mattress 50
at a breaking joint 36 between folding sections
31 of said mattress 35 so that when the bed is
collapsed the mattress 35 will automatically fold
into compact form under the action of the levers
23 and 24 and the lifter strap 34 connecting with 55
2
2,127,025
each pair of said levers Z3 and 24 as is clearly
shown in Figures 2 and 3 of the drawings.
When the bed is to be occupied on the ex
tending cf the lazy tongs B the mattress 35 will
therewith in spaced parallel relation to each
other for extension and contraction without and
within said cabinet, a ?exible mattress support
yieldably ?tted at opposite ends with the con
nections between the lazy-tongs, the cabinet and
automatically unfold and be supported upon the
support I3 which is rendered taut when the lazy . the foot board, respectively, a sectional, foldable
tongs B are extended, the levers 23 and 24 being mattress on said mattress support and having
lowered on the extension of said lazy tongs.
When the bed is collapsed under the action of
10 the lazy tongs B the levers 23 and 24 will be
swung upwardly and in this manner automati
cally folding the mattress 35 so that the latter
and the said bed will become concealed within
the space H in the cabinet A as is shown in
15 Figure 4 of the drawings. The links l8 are of
considerably greater length than the links IS,
the latter being slightly curved and are pivoted
at l9’ to the end toggle levers of the lazy tongs
B. These links I8 and I3 when the lazy tongs
20 B have been extended will sustain the foot sec
tion or board l2 in a perpendicular position,
there being no possibility of the closing of the
lazy tongs B accidentally when the bed is occu
pied due to the fact that the weight upon the
25 mattress through such occupancy is distributed
throughout the length of the lazy tongs later
ally to opposite sides thereof and the strain is
placed at the crossing points l5 of the levers Ill
while strain in a longitudinal direction is nil.
The drawer It] carries handles 38 and the foot
30
section or board also carries the handles 39. The
bed is extended and collapsed in an easy man
ner through the operation of the lazy tongs B
and also the mattress 35 is automatically folded
35 and unfolded as hereinbefore set forth.
It is, of course, understood that the mattress
35 is supported by the spring tensioned strap
when occupied for sleeping or resting purposes.
The links 26 and 3| through their connection
with the lazy tongs B and the levers 23 and 24
40 will automatically swing the said levers verti
cally on the folding and unfolding of the bed,
the levers 24 being slidably connected by the
connections I‘! with the tracks 25 so that the
lazy tongs when collapsed will be housed well
45
within the cabinet A.
What is claimed is:
1. A collapsible bed comprising a cabinet hav
ing a displaceable front forming a foot board,
a pair of lazy-tongs arranged between the cabi
net and the foot board and havingv connection
fold lines remote from its ends, lifting levers on
each side of the lazy-tongs pivoted on the lazy
tongs near each end thereof, respectively, and 10
extending toward the center of the lazy-tongs,
means operativelyconnecting the outer ends of
said levers with the lazy-tongs whereby retract
ing the lazy-tongs lifts the inner ends of the
levers, and resilient lifting members interposed 15
between the mattress and mattress support and
connecting each lever with a corresponding lever
on the opposite side whereby on retraction of
the lazy-tongs the mattress will be lifted along
fold lines remote from the ends thereof and
folding of the mattress assisted.
2. A collapsible bed comprising a cabinet hav
ing a displaceable front forming a foot board,
a pair of lazy-tongs arranged between the cabi
net and the foot board and having connection
therewith in spaced parallel relation to each
other for extension and contraction without and
within said cabinet, a flexible mattress support
yieldably ?tted at opposite ends with the con
nections between the lazy-tongs, the cabinet and
the foot board, respectively, a sectional, foldable
mattress on said mattress support and having
fold lines remote from its ends, lifting levers on
each side of the lazy-tongs pivoted on the lazy
tongs near each end thereof, respectively, and
extending toward the center of the lazy-tongs,
means operatively connecting the outer ends of
said levers with the lazy-tongs whereby retract
ing the lazy-tongs lifts the inner ends of the
levers, resilient lifting members interposed be
tween the mattress and mattress support and
connecting each lever with a corresponding lever
20
25
30
35
40
on the opposite side whereby on retraction of
the lazy-tongs the mattress will be lifted along
fold lines remote from the ends thereof and 45
folding of the mattress assisted and tensioned
straps connected at intervals with the lazy-tongs
and underlying the mattress support intermedi~
ate with respect to the tensioned ends of said
support.
