This invention relates to cotv structures ‘and/the by means of special end’ hinges [4. These hinges
like, and includes among its important objects the
are in the form of a pair of triangularly shaped
provision of a cot which may' be folded up when
not in use, and which may be otherwise-rrfolded
plates l4 having a plurality of mounting holes l5
(Fig. 6) adjacent the severalcorners thereof, and

the base‘ angles or corners opposite its apex.
Hinge plates M are mounted on their respective
frame members l2 and I2’ with their cars 16 in
overlying relation, there being a pintle or rivet l'l .
extended through one pair of ears on opposite
innerspring structure which is simple andruggedi
and which affords increased comfort to the :user.
A further object is a cot structure comprising a
10 central frame section having depth, and~having
short end sections hinged thereto at each of- its
ends, together with especial hinge devices adapted
to hold the end sections in raised position 'to
plates, and in this way, the section I 2’ may be
pivoted relative to the section I2 from the folded
condition seen in Fig. lto the extended condition

along line 1-1; while
Fig. 8 is a vertical median‘ section of the erected
cot arranged as a table.
A preferred form of the invention includes a
45 frame II] of elongated rectangular formvand' com
prised, as seen in Fig. 3, of a pair of lateral franrie
rails II and a pair of longitudinal-‘frame rails l2,
all of oblong and preferably rectangular-cross
section, arranged end to-end‘ with their lateral or
50 side edge portions l3 of “each rail disposed in par
allel planes (Fig. 5), thus giving a maximum of
depth to the frame, for reasons which will herein
after appear.
Each of the longitudinal side rails l2 has a
55 movable section I2’ attached to the ends thereof
the sections l2’ are in the position seen in Figs. 6
and 8, in which the arms l8 ?rmly hold the'sec
tions for the purpose of ‘supporting a table section
or top 20.
Each of the endwise or lateral frame members
I I is provided with an edge strip 2| which extends 30.
laterally outward of the member from its narrow
side, and whenlthe end sections I!" are folded up
into the position seen in Fig. 8, the top 20'may be
securely‘ lodged in the ledge formationv provided
by these opposite edge strips, while the several
holding arms l8 on the hinges assure adequate
support for any reasonable load applied to the
Suitable leg members 23 are pivotally connected
to the main frame l2 as at.24, and desirably may ‘Y
be arranged in pairs with the legs of each pair be-~
ing connected together by stop. rods- 25 attached
to each leg at such’ a distance from they pivotal
points 24' that when the legs are extended, as in
.Fig. 2 for example, these stop rods will bear ?rmly
against the underside of the frame, thus limiting
the outward or extending movement of the legs
and giving greatly increased structural support
to the frame. Thepairsof legs are also desirably tii Q
provided with tie rods 26, which, in cooperation
with the stop rods, provide a very firm cot struc
ture. The particular leg structure briefly out
lined above, is described and claimed in my co
pending application, Serial No. 140,370, ?led May 55

A novel “innerspring” arrangement is also pro
vided in the present invention in the form of a
bottom fabric or canvas covering 28 having its
marginal edge portions folded under and stapled
to the bottom narrow edge portions of the central
or main frame I2, as at 29 (Figs. 4 and 5) near
each of its ends the central frame section l2 has
10v a long thin strip 30 of fibre or metal of the same
width as the frame rail and extended laterally
across the frame for attachment to the central
understood that the appended claims are to in
clude all said modi?cations and changes and all
equivalent expedients for accomplishing the
structure disclosed.
Having thus-‘described my invention, what I 5
claim as new and desire to protect by Letters
Patent is:
1. A cot including a central frame section and
end sections attached by means of hinges to op
posite ends of said centralsection and adapted 10
to fold back onto the latter, means co-operable
with said hinges for holding said end sections in
part of the same by any suitablemeans such<as . a substantially upright position relative to said
the nails 3|. In this manner, the main longitudi'l ' " central section, a removable table section adapt
,15 nal side rails l3, the end strip 30, and the fabric . ed to-?t between said central section and said 15
bottom 28 provide a well in which is disposed a set end sections when the latter are folded onto
of coil springs 32, over the top of. which is laid'a
the former, and means on said end sections and
padding 33 (Figs. 3, 4, 5).

port said table section in position on the end
After the springs 32 are arranged on thebot
20 tom 28, a protective closing sheet or'strip 34 sections in their aforesaid upright position.

Over the protective sheet or cover‘ 34 is then
laidv a full length cradlev fabric 36 of canvas
or the like, and this fabricis stapled down ‘all
ing a folding leg structure and movable‘ end sec
tions attached by means of hinges at opposite
endsiof said central section; means co-operable
with said hinges vto hold said end sections in a
determined raised position to support a table
along the top horizontal edge surface of the whole
frame, including the main frame portion l2 and
the two hinged end sections l2’, as indicated at
section, a removable table section, and means on
said .end‘ sections to receive and retain said table
section in place when said end sections are in
off the entire spring assembly.
It will thus appear that when the load of an
3..A cot including a main frame section and
movable end sections at its opposite ends,'to
gether with a ?exible cradle member extended
over and attached to said main and end sections,
the latter being pivotally ‘attached to the main ill
se'ction‘by means of hinges constructed to per
mit-the folding of the end sections back onto
occupant is appliedto the cot in its fully ex
tended condition (Fig. 2),, that this load will be
distributed in part over the 'top cradle fabric
35 36, somewhat in the manner of the ordinary cot,
and much of this part of ‘the load will be divided
between the middle and two. end sections. ‘In
addition, .an appreciable part-of the load will be ‘ the main section in spaced relation to‘the latter,
transmitted to the protective cover sheet 34 in such that a substantially planar table member
may be held between'said main section and'said
40. the central region of the cot Where the load is
concentrated, =while still another considerable folded-back end section, means arranged with
portion of the load‘ is sustained by the spring said hinges for holding the same in a prede
assembly 32,'yieldingly supported on the bottom termined' position to position said end sections in
substantially upright relation'to said main sec
canvas or fabric 28. .
Thus, the several objects of the invention are tion, a substantially ' planar table member‘re
_ accomplished in a simple’ and economical vfashe
ion, and theresulting cot‘ structure, in addition
to being rigid, very strong and durable, is .con
siderably more comfortable than-other forms of
An additional feature ,of‘the invention'resides
in the'arrangement of the hinges l4 and the
position of the pintles l1 thereof a distance above
the topvedge of the side rails l2such that when
55 the movable end sections are folded back upon
the main section in the manner shown in’ Fig. 1,
a space indicated at 40 remains, between the con
fronting edges of the‘ folding end sections I2’
and the top edges of the middle rails l2, which
60 is adequate toreceive theytabletop member 20
and hold the same in place for transportation
with the cot structure in its folded condition. I In
the latter condition the board is prevented from
sliding out of its seat in a' lateral direction by
the protruding portions [6 of the hinge mem
The preferred form of "structure set forth
herein for illustrative'purp‘os'es may be variously
re-arranged and changed without departing ma
70 terially from the spirit of the invention, and‘it is
ceivable on the upper ends of said end sections
in their raised position as aforesaid, means on
said end sections preventing dislodgement of ‘said
table member, the latter member being received
between said main section and said end‘sections
when the latter are folded back in the manner

main frame section with movable opposite" end
sections‘ adapted to- fold back onto the main sec
tion, hinge means connecting said endand main
sectionsfor the purpose aforesaid, means form

position said end'sections in substantially raised
position relative to said main section, said hinge 60;
means being adapted to provide a space between
said end and main sections When folded back
as aforesaid, a removable table member adapted
to ?t into and be held in said space between the
endand main sections, the outermost free lateral 65
