Referring now to the drawings, and more particularly
to FIGS. l-4, l have illustrated my invention as compris
ing a frame, indicated generally by the numeral 10, upon
which is pivotally mounted a table 11 supported by a
brace, indicated generally by the numeral 12. The brace
12 is adjustable as to length and, therefore, may be used
the hinge 29 againstthe outwardly facing bearing sur
faces 35-35 of the bearing members 2d so as to fix the
hinge in any desired location upwardly or downwardly
of its upright 15.
v
.
A guide, indicated generally by the numeral 40, pro—
jects from the one leg 32 of each hinge into the slot 18 and
functions to maintain constant the attitude of the one leg
32 of the hinge. The guide 40 is made up of a screw 41
which is seated in a washer 42 and passes through a
spacer 43 outwardly of the slot 18 into a suitable threaded
aperture in the one leg 32 of the hinge. The spacer 43
is of such an axial dimension that the washer 42 is close
to but is not in binding contact with the inwardly facing
bearing surfaces 36-36 of the bearing members 20.
Thus even though the hinge 32 is vertically adjusted and
?xed in any desired position by releasing the knob 33
and by retightening the knob with the hinge in the de
sired position, the hinge will maintain its constant verti
cal attitude.
-
The other leg 50 of each hinge 32 is ?xed to the lower
surface of a respective one of table supports 51-51, each
of which is ‘?xed to the lower surface of a rectangular
table member 52, the supports 51 and table members 52
making up the complete table 11.
Each brace 12 comprises a pair of bars 57 and 58
provided with guides 59 and 60, respectively, which are
?xed to their respective bars in such a manner (as is
perhaps best shown in FIG. 2) that each bar and guide

, From the above description it will be obvious that the
alternative embodiment functions in a manner similar to
the ?rst described embodiment of the present invention.
The alternative embodiment, however, does have more
?exibility of adjustment. For example, the angle of the
