(Cl. 311—99)
My invention relates to foldable legs for card tables
and the like, and it has for its primary object to provide
rearwardly curving frontal surfaces 19 of the wall-pro
vided cam portions 21}.
The rear camming edges 21 of the side wall-provided
cam portions 24) slant inwardly and rearwardly as shown
in FIG. 2 and terminate at the site of the rearwardly
extending wall edge-provided seat 22 which is aligned
with and in part formed by the lower edge of the rear,
or bight wall 15 of the bracket. As indicated in FIG.

end wall edge-provided seat 22 is adapted to be engaged,
legs in operative position and likewise in inwardly folded
position against the bottom of the table top.
The invention contemplates a novel leg pivoting bracket
or closely approached, by a leg-carried and spring backed
stop 23. This stop 23, along with leg 11, is actuated
outwardly by cam surfaces 21 to retain the leg in op
member for attachment to the underside of the table top
and a shiftable leg-carried abutment which is preferably 15 erative position and in bearing engagement with the low
er edge of the bight or rear wall 15 of bracket 13.

Coming now to the leg-carried stop 23 to which in
the leg in operative position and to bear against another
cidental reference has been made, FIGS. 1 and 2 of
bracket portion to secure it in folded position adjacent
the drawing illustrate the leg 11 as having slidable there
the under table top surface.
An important object of the invention is to provide 20 on the oversized stop-providing sleeve 23 having at its
simple, ef?cient and durable, but inexpensive means for
the purposes speci?ed which is readily operable and ad

A further and more speci?c object is to furnish a novel

sleeve form leg-carried stop which is spring actuated
to make constant bearing engagement with the leg-pivoting
It is to be noted from the full line showing of FIG.

Invention also resides in the leg-pivoting bracket and 30 provided seat 22; and that curved outer portions 23a
of the sleeve end engage cam edges 21 to cause the up

sleeve 23 in all operating positions of the latter. The

FIG. 1;
FIG. 3 is a cross sectional view taken on the line 3-—3
of FIG. 2;
FIG. 4 is a detail view of a leg carried spring support
which is embodied in the invention; and
FIG. 5 is a perspective view of the leg carrying bracket.
Referring to the drawing by reference characters, nu
meral 10 indicates the table top, one of its supporting
to slidably support sleeve 23, the leg 11 having opposite
sides provided with aligned transverse grooves 24 as
shown in FIGS. 1 and 3 to receive the opposed inner
edges 25b of the stop member 25.
From the foregoing description it will be apparent how
the spring actuated sleeve 23 retains leg 11 in the op
erative full line position of FIGS. 1 and 2. When the
table is to be stored, the respective stop sleeves 23 are
legs being indicated at 11 and shown as pivoted, at at 12,

As illustrated, the bracket is seen to be U-form in
horizontal section (FIG. 5) and to comprise the laterally
top 10. In this position the pressure of sleeve end 23a
spaced side walls 14 which are connected by the bight or
against the seat-providing bracket edges 18 retains the
rear wall 15. Attachment of bracket 13 to the underside
of the table top 10 is made by screws or the like 17
which extend through holes in the outwardly extending
top mounting ?anges 16 of the bracket side walls 14.
The side bracket walls 14 perform very important func
tions as will be explained hereinafter. Referring to FIG.
2, it is noted that bracket side walls 14 have upper frontal
edge portions 18 commencing at the site of mounting
?anges 16 and which edge portions constitute a seat for
a leg-carried stop when the leg is folded inwardly against
the table top. The frontal seat-providing edges 18 are
substantially perpendicular to mounting ?anges 16 and
extend downwardly for about two-thirds of the depth of
leg adjacent the table top 10.
Having thus described my invention, what I claim is:
1. In a pivoted table top-carried leg which is swing
able from a depending operative position to a position
underlying the table top, a bracket for attachment to
the underside of the table top and having a depending
