time, the toggle braces 45 are extended into the condition

portions of the respective rails for swinging to and from
a supporting position extending perpendicularly from said
10 rails from and to a folded position in which each leg is

additional and similar ?ats and grooves may be formed
at the opposite ends of these respective end slats in order
that the matter of ?tting of the cover 11 onto the table
frame may, be more convenient.

In addition, when cover 11 has been extended and
when the ?ats and grooves of diagonally opposite corners
of the cover have been ?tted over hinges 28, tabs 17
are then to be attached to the framework by the inter
engagement of snap elements 19 of the tabs with snap
elements 21 on the frame. In this manner it will be seen
that the cover overlies the framework, assists in rigidity
ing the framework and is attached thereto in a manner
which will deter any slippage of the cover relative to the
framework.
It further will be seen that when it is desired to dis
mount the table, the tabs 17 need only be simply detached
from the snap elements 21 of the frame, the cover re
moved therefrom and the framework folded into the com
pacted condition heretofore described, legs 3? being re
spectively folded into their associated rails with the toggle
‘braces being folded thereinto and housed therein and
with the feet 47 of the legs engaging the ?anges of the
rail members. Thereafter, the rail members are folded

overlapping end portion of the inner side of another ad
