‘Application September-22, 1937, SerialNo. 135,138
2 Claims. (Cl. 155-127)
My present invention relates to folding nursery
chairs andis in the nature of an improvementv
upon the structure shown in my Patent No.
1,910,736, issued May 23, 1933. Inasmuch as the
5 construction in the center of the seat of the chair
has not been essentially changed, I have vvre
frained from illustrating this in' the present draw
ing, it being possible to determine this construc
tion from my prior patent. The present inven
10 tion pertains more particularly to the locking
mechanism for the tray and the latch for hold-v
ing the chair against accidental folding.
Among the objects of this invention are to pro
vide improved means for latching the tray in po
15 sition on the chair arms; to provide improved
means for latching the back to one of the arms
so as to prevent inadvertent collapsing of the
chair; and such further objects, advantages, and
capabilities as will hereafter appear and as are
20 inherent in the construction disclosed herein. .
In the drawing annexedhereto and, forming a
part hereof,

Fig. 1 represents a side elevation of my im
proved chair in assembled and latched position,
Fig. 2 represents this chair with the tray in
7 position ready to be placed on the arms and se
cured in place thereon;
Fig. 3 represents a fragmentary’ edge view of
O one end of the tray and illustrating the projec

erates with an arm in holding the tray in posi

I shall now refer in greater detail to the an
35 nexed drawing for a more complete description
of this invention. A pair of loops I and 2, hinged
' together at 3 form the legs for supporting the
seat 4. The ends of the loop I are pivotally con
nected by a pair of bolts 5 which also connect
40 the uprights 5 of the back ‘I to the seat 4. A
pair of arms 8 are pivotally connected at 9 to
the uprights 6 and at It to the‘ posts H. The
lower ends of these posts II are pivotally con
nected at I2 to the seat 4, the pivot points 5, 9,
45 Ill, and 12 forming the angles of a parallelogram.
A stud I3 projects laterally from one of the up
rights 6 and is designed to be engaged by the
notch M in the latch member I5. It will there
fore be apparent that when the latch member I5
50 is engaged, as shown in Fig. 1, the chair will be
- held from collapsing unintentionally.
‘
tend. forwardly and upwardly from the posts ll ' 6
and engage in front of the extensions l8 when
the chair is completely set up, asrillustrated in
Fig. 1. From the foregoing it is apparent that
when the chair is assembled and set up,_ as in
Fig. 1, with the latch member l5 engaging the 10
stud l3, as shown in this ?gure, it will be impos-.
sible to. remove the tray IS without bending or
breaking some part of the chair, unless the latch
I5 is ?rst disconnected ‘from the stud Hi.
When it is desired to use the upper'part of the 16
chair with a toilet seat, the nuts may be removed
from the bolts 5 ‘and the legs detached so that
downward projections 4a and 41) from the seat 4
may ?t within the opening in the toilet seat and
hold .the two against any substantial relative 20
movement. The opening in the chair'seat has
not been shown in the present drawing since it
does not differ essentially from that shown in my
prior patent referred to above.
While I havedisclosed what is now regarded as 25

sire this disclosure to be regarded as illustrative
only and not to be interpreted in a limiting sense.
Having now described my invention, I claim:
1. A folding chair comprising‘ in part a-seat 30
member having a back pivotally connected there
to to swing forwardly and backwardly with re
spect to the seat, into open and folded condi
tion, arms pivotally connected to the back and
extending above and substantially parallel to the 35
sides of the seat, posts pivotally connecting the
forward end portions of the arms to the sides of
the seat membenand a tray slidable on the arms
and having downwardly projecting elements hav
ing laterally extending ends to engage the arms 40
and guide the tray with respect thereto, said ends
being slidable along the under side of said arms
into engagement with said posts, and said posts .
having projections extending forwardly there
from and upwardly into positions in front of said 45
ends whereby to prevent the tray from being re
moved from the arms.
2. A folding chair comprising in part a seat
member having a back pivotally connected there
to to swing forwardly and backwardly with re- 50
