The chief object‘of this invention is to provide
a table structure which is of knock-down char
acter and which may be readily extended from
the knock-down position to‘the table forming po
sition and which may be readily transported,
10 whether in the knock-down or table forming con
dition.
'
‘
Another object of the invention is to so ar
range the parts of such a table structure that
when collapsed or knocked down, the several
parts occupy a minimum amount of space.
Another object of the invention is to construct
a table of the aforesaid character of but a mini
mum number of parts.
"
The chief feature of the invention consists in
20 the formation of a table structure, whereby the
aforesaid objects are accomplished.
- -
Another feature of the invention consists in
providing a receptacle in the table top which is
yieldingly retained therein, whether the table be
25 knocked down or in table forming position but
which may be readily separated from the table
for cleaning purposes, said receptacle being‘ so
positioned with respect to the table top that when
the top is arranged in collapsed positiomthe base
30 of said receptacle does not interfere with the
full collapse of the respective parts of the table
into the minimum volume if the depth of said
receptacle is of appreciable character.
‘
Another feature of the invention consists in'v
35 the provision of means when- desired, for-pos
itively interlockingly connecting the movable leg
to the tiltable‘ table top when the table structure
is in table forming position.
'
'
The full nature of the invention will be under
40 stood from the accompanying drawing and the
following description and claims:

When in table forming position, the top lies in
a plane ‘at right angles to the plane of the legs
l0’ and II but due to’ the play in the hinges/it
may betilted ‘slightly above the'horizontal, the 20
purpose of which will be set forth hereinafter
with respect to the forms of the invention shown
in Figs, 3 and 4. Herein the legs 10 and H are
shown extending upwardly beyond the plane of
the table top whenin table forming position and‘ ‘25
such extensions are indicated by the numerals
l1 and I8 for legs l0 and i I, respectively} ‘Such
extended portions also are connected'by across

the position of the receptacle is such relative to
the cross bar 20 when the parts are in table form
legs, into a horizontal position, ‘or a position
transverse to the legs. As shown clearly in Fig. l,
ing position, that said receptacle offers no .inter
ference to the movement of the several parts into
table forming position or to the complete col 30
lapse thereof into the knock-down position.
In Fig. 5 of, the drawing,‘a modi?ed form of
top and movable leg interlock is illustrated. In
said ?gure 316 indicates the top, 312 the leg and
330 a spring clip anchored as at 334 to the bot 35
tom of the table top 316, and having its tongue
the stop 30 is positioned so that it clears the cross
30 bar 21 and the length of the stop is such that it
does not project beyond the two outermost planes
of the table structure when collapsed.
In Fig. 3 a modi?ed form of stop, which has
locking characteristics, is illustrated. In this
form of the invention, the table top 116 includes
the stop 130 depending therefrom and the mov
portion yieldingly associated with the aperture
able or third leg 112 is recessed as at 131.
It will be remembered that mention was made
40
331 in the leg 312. The spring clip 330.has its
spring end of spoon‘, formation, the same being
indicated as at 332 and it includes a bend portion 40
333, which imparts the resiliency to the ?xture.
This form of the invention differs from that
shown in Figs. 3 and 4, wherein only lateral move
ment of the leg is prevented in that the present
?xture not only prevents the same but also pre 45
hereinbefore of a slight play in the hinge struc
ture and said slight play permits the table top to
be elevated slightly above the horizontal, refer
ence being had to the distance between the table
top 1 I6 and the top of the leg 1 12 when the parts
are being arranged in the table forming position.
Such additional tilting movement permits the
pin 130 to register with thevopening or recess 131
and when such registration occurs the table top
is lowered so that the pin seats in the recess 131.
In Fig. 4 a modi?ed form of the invention is
illustrated and in said ?gure, 216 indicates the
table top and 212 the leg. In this form of the
invention, the stop portion is indicated by the
numeral 230 and comprises a downwardly di
rected portion of a strap having a base portion 233
55 and an inclined approach portion 232. Ascrew
or similar member 234 secures the base portion
233 to the underface of the top 216. The top
of the leg 212, preferably but not necessarily, is
recessed as at 231‘ to accommodate the head 235
60 of the screw 234 or other anchorage means.
In this form of the invention, no care in look
ing the combination stop and interlock is re
quired, because after the table top is elevated into
approximately the horizontal position, the third
65 and movable leg is pivoted into table forming
position until it engages the approach portion
232 and continued swinging movement ofsaid
third leg automatically tilts upwardly the
table top beyondv the horizontal until the leg
70 drops into the groove formed between the ap
proach portion ‘and the stop 230, further pivot
ing movement of they leg then being prevented and
return pivoting movement of the leg also being
prevented;

The friction ?t is such also that the re
ceptacle readily may be forcibly ejected from the
well whichpermits cleaning thereof. As shown
clearly in

stop 30, which is adapted to abut against leg 12,

In Figs. 1 and 2 of the drawing, there is illus
trated a well 411 which consists of a hole formed
'
When the table is to becollapsed, the table top
vents upward movement of the table top relative
to the leg, although in Fig. 3, if the pin 130 were
of tapered character, it might be possible to have
a friction taper ?t which would accomplish the
same purpose. However, this has the objection 50
that after several engagements the size of the pin
and hole would be such that this function would
be lost, because it is desirable in the form of the
invention shownin Fig. 3 that the top rest on the
top of the leg. The free end of the clip 330 when 55
it engages in the end of the recess 331 serves as
a stop for limiting leg swinging movement.
In Fig. 6 a form of the, invention similar to that
shown in Fig. 5 is illustrated, but in this form,
the opening 43! in the leg 412 extends entirely 60
through the leg and transversely thereof as dis
tinguished fromthe opening.131, as shown in
Fig. 3, which is in longitudinal alignment with
the leg. The clip 430 is suitably secured to the
table top 416 as at 434. It includes a shoulder or 65
offset portion 433 which serves as a stop for
limiting swinging movement of the leg. The free
end of the clip terminates in the portion 432 and‘
this is positioned on the opposite'side of. the leg
412 when associated therewith. The inherent 70
resiliency in this clip normally holds down the
table top to the leg 412. "
'
-
'
I ' The angular end 432 of the clip which has a
cam effect for ease of :pa'ssage'to' and fro through
the slot, 'is normally held~ in rigid relation, as 75
2,055,007
shown, to lock the leg to the table and prevent
swinging of the leg.
In Fig. 7 a modi?ed form of the invention is
illustrated. This form» of the invention is shown
at right angles to the form shown in Figs. 4 to
6, inclusive. The clip 530 includes anchorages
534 for connection to the bottom of the table
top, not shown, and the clip includes two pro
jecting portions 533 which have free ends directed
10 towards each other in curved relation as at 532
for gripping the included portion 5l2a of the leg
5|2, formed as a result of the two recesses 53L
A modi?ed form of the aforesaid is a reversal
thereof and such form would have a single open
15 ing 531 and the two portions 532 reversely di
rected and engaging the two opposite sides of the
single opening 53L The two portions 533 he
parallel to each other and at right angles to the
base portion 533.
20
Integral with the base portion and as an ex
tension thereof and bridging the gap between the
two portions 533, is a portion 533a which serves
as a stop to prevent further swinging movement
of the leg beyond the predetermined position.
25 The normal spacing between the two portions 532
when not associated with the leg is less than the
width of the partition portion 512w‘. Further
more, the top edges of the portions 532 are spaced
from the bottom of the table top such that when
30 the leg and the locking clip are associated to
gether, the table top and leg are secured to
gether and thus separation of the two is pre
vented, both swingingly and tiltingly, until the
two are forcibly disassociated.
