2 Claims.
This invention relates to a novel and improved
foldable card table of the portable domestic type
now generally used in the home and appropriate
places of public amusement, and it has more par
5 ticular reference to a structure characterized by
a distinctive top and a proper coinciding collapsi
ble leg support.
The improved table construction is character
ized by a new and improved duplex leg frame sup
port having expeditiously usable and satisfac
torily performing adjusting and retention means
for the leg frames.
Speci?cally, novelty is predicated upon the
adoption and use of U-shaped pivotally mounted
15 leg frames positioned on opposite sides of the
under surface at the top wherein said frames are
provided with self-adapting stay units slidably
cooperable with latch equipped means carried by
the under side of the top, said features being
particularly designed and coordinated to insure
efficient and dependable results.
.Though of a collateral nature, the improved
construction is further individualized by the em
bodiment therein of a unique charted top of a
25 predetermined diagrammatic nature whose fea
tures contribute in providing as an added fea
ture, a gameboard susceptible of practical usage
for playing checkers, cribbage and similar games
of chance and skill.
Then too, the embodiment adopted possesses
in addition to ornamentation and features of
design, conveniently located corner openings to
accommodate temporarily usable service acces
sories such as ash trays, drinking glasses and simi
35 lar utensils so frequently needed by the particip
ants and guests.
Other features and advantages will become
more readily apparent from the following de
scription and drawings.
In the drawings:
Figure 1 is a bottom plan view of a folding card
table with the legs folded showing to advantage
the particular novelty hereinafter claimed.
Figure 2 is a substantially central sectional view
through the table with the leg frames down in
supporting positions.
Figure 3 is a central longitudinal section of a
fragmentary type taken on the plane of the line
3-3 of Figure 1.
Figure 4 is a perspective view of one of the leg
frame stay members.

View of one of the spring pressed detents or
The table top, which is preferably of wood or
(Cl. 311-87)
some composition light-weight material is in
dicated by the numeral 8. It is of conventional
proportions and preferably rectangular in top
plan View. Surrounding themarginal edge or
perimeter is a correspondingly shaped rim made
up of the edging strips 9. These are of duplicate
wood construction and are suitably secured in
place to be flush with the playing surface and to
project below the underside to provide the de
sired apron-like effect shown in Figure 2. By 10
preference the upper edge portions of these strips
9 are rabbeted or grooved to form ledges to ac
commodate the edge portions of the top or board
8. Moreover, as shown in Figure 1 the abutting
ends as indicated at it are of desired curvature 15
so as to form a portion II of the circular corner
opening of hole l2. The remainder of this hole
is formed by a correspondingly curved edge por
tion l3 of the complemental corner blocks l4 suit
ably fastened to the underside of the table. These
corner blocks are provided with bearing holes I5
to accommodate the trunnions or journals on the
ends of the cylindrical bar member I6 of the leg
frames. The legs are differentiated by the numer
als I‘! and are arranged in pairs and are foldable
in superimposed relationship when not in use as
shown in Figure 2 and obviously the legs are pro
portioned so as to permit them to swing within
the area of the rim surrounding the marginal
portion of the top. The con?guration of the legs 3O
may be of any appropriate design to provide for
symmetry and balance in appearance, as well as
in utility. In the arrangement shown in Figure 2
the leg frames are arranged in opposed parallel
ism and are swingably mounted between the re
spective or complemental sets of corner blocks
l4. Thus, when the table is held up with its
underside facing the floor the legs have a tend—
ency to swing out and down by gravity to open
or unfolded positions.
I call attention at this time to the rail l8 fast
ened centrally to the underside of the top. This
is located centrally between and parallel to the
legs ll’ of the respective frame. Then as shownv
in Figures 2 and 3 it is provided with longitudinal
superposed parallel grooves or guideways I9 and
20. The inner ends of the grooves overlap and
are formed with depending lateral end notches
2| which function as keeper seats. These keeper
seats are adapted to accommodate the straight
across bight portions 22 of the substantially V
shaped stay units 23. The diverging arm por
tions 24 terminate in outbent pintles 25 pivotally
connected with the complemental legs. It is evi
dent therefore, that the portions 22 of the units 55
23 ride in and out in the guideways or grooves l9
and 20 and when the legs are spread apart, the
portions 22 drop down into the keeper seats 2|.
To guard against accidental displacement when
the table is set up for use I have found it ex
pedient and practicable to associate with each
keeper seat a latch or catch.
This comprises a
cylinder 26 set into a socket having a ?ange 21
at the open end, which ?ange abuts the outer end
10 of the socket and serves as a sort of a wear plate
for the coacting portion 22 of the coordinated unit
23. Located in the cylinder is a coil spring 28
which forces a plunger 29 out, said plunger being
provided with a ball-head 30 performing the dou~
15 ble function of a retention element and cam. In
cidentally, the open end of the cylinder 26 at the
point where the ?ange 21 joins is struck in to
provided an annular shoulder to limit the out
ward sliding movement of the plunger 29 as
20 shown in Figure 5.
By placing the cylinder as
shown in Figure 3, the cam head 3G partially
bridges the entrance to the keeper seat 2| and is
thereby properly located to provide the requisite
snap action.
It is evident, however, that any
25 other suitable type of a catch may well be em
ployed. The one shown is desirable in that it
recedes to allow the trip or bight portion 22 of
the unit 23 to conveniently snap into the keeper
seat 2!. Also, the cam coaction between these
30 features permits this trip 22 to jump out from the
seat 2| by putting a slight manual pressure
against it through the medium of the legs. Or
stated otherwise by turning the table frame up on
one edge and then catching hold of the two leg
35 frames they can be moved readily toward each
other and this slight inward movement auto
matically releases the stay devices 23 so that they
can slide to proper collapsed or folded position.
As thus far described’ it will be seen that the
40 principal structural novelty resides in the spe
cially designed corner blocks I4 serving as sup
ports for the journal equipped ends of the rocker
shaft portions I 6 of the complemental leg frames.
This is one feature of construction. secondarily,
the use of the opposed leg frames mounted in this
way together with the slotted bar or rail I8 and
the swingably mounted wire stay devices 23 is
an additional improvement. More speci?cally
however, the idea of the spaced parallel super
posed slots [9 and 2|] with the keeper seats 25
at the inner overlapped ends and the associated
spring catches and stay devices 23 is of utmost
Referring again, and brie?y, to the aforesaid
corner holes l2, these function as pockets for
the reception of water glasses, ashtrays and simi
lar accessories especially constructed to ?t into
said holes. Though it has no particular connec
tion with this invention it might be stated that
60 these various service accessories (not shown) are
to be made of disposable material such as paper
or the like for economy and convenience and by
constructing the table to accommodate such ac
cessories this adds further to its special adapta~
catches and the self adapting wire yokes or stay
devices 23 it is to be observed that a table of this
construction may be substantially made of wood
or some equivalent light weight sturdy stock.
This permits the manufacture and sale of a more
or less rigid Warp-proof structure always insur
ing e?iciency of use and obviating the presence
on the corners of metal cleats and the like such
as are so frequently objectionable in tearing one’s
Minor changes in shape, size and rearrange
ment of details coming within the ?eld of inven
tion claimed may be resorted to in actual prac
tice, if desired.
Having thus described the invention, what is 15
claimed as new is:
1. A portable foldable leg structure card table
of the class described comprising a table top hav
ing a marginal depending rim, duplicate blocks
attached to the underside of the table top and
associated with the corner portions thereof and
connected with the adjacent surfaces of said rim,
said blocks being of a thickness corresponding to
the depth of the rim to provide the desired flush
formation between the lower edges of the rim 25
and bottom surfaces of said blocks, a pair of dup~
licate U-shaped leg frames, said blocks being pro
vided with socket forming bearings, the adjacent
ends of the bight portions of said U-shaped leg
frames being provided with trunnions, said trun 30
nions being journaled for oscillation in said bear
ing sockets, the leg members of said frames being
swingable into overlapping relationship in a man
ner to permit the frame, when folded, to be con
?ned with the depth of the surrounding marginal 35
rim, the combined thickness of the overlapped
legs being substantially equal to the thickness of
said blocks, and slidable stay units pivotally at
tached to the respective legs of said leg frames
and cooperable with said table top.
2. In a structural assemblage of the class de
scribed, a table top provided on its under side
with a longitudinal rail, the ends of said rail ter
minating in spaced relation from adjacent mem
bers on the marginal portions of said table top, 45
said rail having a central longitudinally elongated
notch formed in that face abutting the under
side of said top and said notch constituting a
guideway, said rail being further provided with a
longitudinally elongated slot forming a second 50
guideway, one end portion of the slot underlying
the major portion of said notch, one end of said
notch being formed with a counter-notch, and
one end of said slot being provided with a corre
sponding counter-notch and said counter-notch 55
es constituting keeper seats, a spring-pressed,
cam-equipped latch associated with each keeper
seat and cooperable with the entrance portions
of the keeper seats, U-shaped leg frames hing
edly attached to the top and provided with sub 60
stantially V~shaped stay units, the inner ends
of said stay units being con?ned in the afore
mentioned guideways for cooperation with the
keeper seats and latches.
