Claims.
This invention relates to folding tables, more
particularly of the card type although not so
limited, and the primary object thereof is to
provide a tablelof this type which‘has improved
5 means for locking the tablel'both in folded and
l
unfolded positions.
‘
A further object of the invention‘ is to provide
a table of this ‘type wherein opening thereof can
be accomplished‘ more easily and quickly, and
10 in its more speci?c aspect by'mere- positioning
of _ the table with its legs ‘pointing 'to‘jthe ‘floor
and then lifting same, whereupon the legs will
automatically assume operative position and
willbeautomatically locked.‘
'
“
Still further‘ the invention aims to provide
locking means which form a part of the opening
and closing means for the, legs.
The invention still further aims to provide a
table of this type wherein all of the operating
mechanism for the legs is connected to the side
rails of the table, leaving the top of the latter
free of any connections with the operating
mechanism.
In the drawings,Fig. 1 is a bottom plan View showing the legs
25
in section and showing in dottedlines the initial
position of the locking lever to unlock the legs
for unfolding, and showing in full lines the po
sition of the locking means when the legs are
15
30 unfolded;
Fig. 2 is a section on line 2-2 of Fig. 1;,
Fig. 3 is a view similar to Fig. 1 showing the
legs in folded position and the locking mecha
nism in locked position;
‘as
Fig. 4 is a section on line 4-4 of Fig. 3;
Fig. 5 is an enlarged detail view partly in
section with the legs in operative position;
Fig. 6 is a section online 6-6 of Fig. 3; and
40
Fig. 7 is a perspective view'of one of the
brackets employed for bracing the legs in un
folded position.
In proceeding in accordance with the present
invention the table has the usual top I which
may be of any form, and which has depending
side rails 2. As shown more clearly in Fig. 5
45
each of the side rails 2 are grooved on their
inner faces as indicated at 3, and are provided
with plates 4 which may be secured in position
in any suitable manner. In each of the corners
50 of the table and abutting the adjacent side rails
there are U-shaped brackets 5 to which the legs
are pivoted at ‘I.
‘
Three braces 8, each of similar form, and a
fourth brace 9 are provided, the latter brace be
55 ing formed in two sections l0 and H, of which
H has a hand operating lever extending’ at‘an
angle thereto, and is pivoted at an intermediate
point at l3 to the adjacent end of the section‘
Ill. The section I] is formed with a. U-shaped
slot M as shown in Fig. 6 to receive a headed 5
stud l5 which is carried by the‘ section II) so
that when the parts are in the position of Fig.
3 it will be ‘noted that the sections l0 and 'II
will be in register, or‘alined, and will function
precisely as the braces 8, thus latching the ‘parts 10
in
folded‘relation.
I
‘
‘
‘
l
The adjacent ends of the‘ braces: 8, are pivoted
together as shown in‘Fig. 5l-by ‘a pin 16 which‘
latter preferably ' has 'antiéfriction' rollers
l'l"
mounted on‘its ends, whilelthelends of the sec- 15
tions [9 and II are likewise secured to the ad
jacent ends of the adjacent braces 8 as shown in
Figs. 1 and 3. The rollers are received in the
grooves 3 and are movable lengthwise thereof,
while prevented from movement out of the 20
grooves by the plates 4.
‘
As depicted in Fig. 7 substantially L-shaped
brackets I‘! are secured to the braces 8 and to
the outer end of section II] of brace 9 for the
purpose of pivotally supporting bracing links I8 25
which latter are pivoted at 19' to the legs 6 and
at I9 to the brackets H, the latter links extend
ing at an angle to- brace the legs 6 as shown in
Fig. 2.
‘
I
For the purpose of tensioning the locking 30
mechanism, a coil spring 20 is provided which is
secured to section II! ‘of brace 9 and to the ad
jacent bracket 5.
In operation, and assuming that the parts are
in the folded position of Fig. 3, the locking lever 35
i2 is moved to the right thereby to disengage
same from the stud I5, thus releasing the braces ‘
8 and 9, and through links l8 the legs will be
moved to a vertical position. At this point it is
to be noted that when the parts are in the folded 40
position of Fig. 3 it is optional with the user to
lock the lever l2 in said position of Fig. 3, or
otherwise expressed, the lever I2 may occupy the
dotted line position of Fig. 1 when the parts are
in folded position. With thelever in the dotted 45
line position of Fig. 2 it is merely necessary to
move the table to a position where its top faces
upwardly, and to then lift same, whereupon the
legs will automatically move downwardly, or one
of the legs can be grasped‘ to move same to a ver- 50
tical position, and the locking lever 12 will be
automatically moved to occupy the full line posi
tion of Fig. 1 wherein all of the legs will be
positively locked in their vertical position and
against movement.

To fold the table it is merely necessary to move
the locking lever I! to the dotted position of Fig.
1 whereby upon grasping any one of the four legs
and moving same to folded position the remain
ing three legs will be correspondingly moved
through the links l8 and the braces 8 and 9, and
as above stated and if desired, lever l2 may be
permitted to remain in the dotted line position of
Fig. 1 so that in subsequent unfolding of the table
10 it will not be necessary to unlock the lever I2.
From the foregoing it will be seen that the
locking mechanism forms a part of one of the
braces and ,when in the position of Fig. 3 same
acts precisely as do the remaining three braces 8.
15 It will also be understood that the spring 20 acts
to hold the parts in the full line position of Fig. 3
thereby holding the lock in its locked position and
against accidental movement; upon the lever I2
being manually moved to the full line position as
20 shown in Fig. 3.

What is claimed is:
l. Inv a folding table, a top having depending
side rails, each formed with a longitudinal slot,‘
legs pivoted to the corners of the top, a series of
braces having their adjacent ends pivoted to

of the braces and slidable in the respective slots
to hold the braces against movement laterally of
the slots, connections between the legs and the
30 braces, one of said braces being formed in sec
tions which are pivoted together and one of said
sections having a manual lever connected there
to, and means to removably lock the sections to
gether, and to unlock same by said lever. .
2. A folding table in accordance with claim 1,
wherein the connections include a bracing link
pivoted to each leg, and wherein the link is
pivoted to the adjacent brace for movement
therewith.
3. A folding table in accordance with claim 1,
wherein one of the sections of the sectional brace
has a coil spring connected thereto and to a
?xed point on the table to hold the sections in
locked position.
4. A folding table in accordance with claim 1, 10
wherein the connections include a bracing link
pivoted to each leg, and wherein the link is
pivoted to the adjacent brace for movement
therewith, and wherein one of the sections of the
sectional brace has a coil spring connected there 15
to and to a ?xed point on the table to hold the
sections in locked position.
5. In a folding table, a topv having legs pivoted
thereto, a series of braces pivoted together at
their adjacent ends, connections between the legs 20
and the braces, means to mount the braces at
their pivoted ends for sliding movement, one of
said braces being formed in sections which are’
pivoted together, a hand lever connected to one
of said sections and means to removably lock the
last named section to the other section by pivotal
movement of said lever.
