1 Claim. (01. 155-141)
This invention relates to folding chairs, and
the primary object thereof is to provide simpli
?ed means for securely and positively retaining
the chair both in operative and folded positions,
against accidental movement.
A further object of the invention is to provide
to the rear legs 2 and have their inner ends
offset and pivoted to the rod I3. For the pur~
pose of holding the braces l5 and I‘! against
movement inwardly of the rod 43, means, for
example, the sleeve I9 is mounted on the rod 01
a chair of this type which can be economically
manufactured; which embodies a minimum of
parts, and one wherein the folding and unfold~
will be noted that the rollers H! are disposed
closely adjacent to the braces l5, so that same
ing operations may be easily ‘and quickly per
The invention has still further and other ob
ment longitudinally and outwardly of the rod it. 1.0
jects which will be later set forth. and manifested
in the course of the following description.
In the drawings:
Fig. 1 is a vertical sectional View of the in-
vention, in operative position;
Fig. 2 is a section on line 2—2 of Fig. 1;
Fig. 3 is a section on line 3-—3 of Fig. 1;
Fig. 4 is a front elevation of the invention in
folded position;
Fig. 5 is a section on line 5—5 of Fig. 4; and
Fig. 6 is a detail view of the guide and wear
In proceeding in accordance with the present
invention, a back I is provided having legs 2;
a seat 3 being pivoted to the back by means
of brackets 4. Front legs 5 are pivotally con
nected to the seat by means of brackets 9. The
30 seat is provided on its under side face with side
rails or members 1, which latter have longitudi
nal grooves 8 formed on their confronting or
inner side faces. The grooves 8 have right an
gular end portions 9 which extend toward the
35 seat.
Combined guide and wear plates ID are se
cured to the inner side faces of the rails l,
for example by means of screws ll. As depicted
in Figs. 1 and 3, the lower side edges of the
40 plates 19 aline or register with the upper side
walls of the grooves 8, or otherwise stated, reg
ister with the side walls of the grooves adjacent
the seat. The plates l0 are likewise formed
with right angular recesses l2, adjacent their
45 end parts, which register with the right angular
end portions 9 of the grooves 8.
Referring particularly to Fig. 3 it will be seen
that a rod I3 is disposed transversely beneath
the: seat and has rollers l4 mounted on its ends
50 which are receivable in the grooves 8 and the
recesses 9 and I2, the rollers engaging against
the undersides of the plates l9. Short braces
l5 are pivoted at H5 at their outer ends to the
front legs 5 and at their inner ends pivoted
55 to the rod l3. Rear braces I’! are pivoted at I8
l3 and has its ends abutting the braces ll.
as well as the braces l‘! are held against move~
Referring now to Fig. 1 it will be seen that
when the chair is in operative position the rollers
M are engaged in the front recesses ll.’ of the
plate it, which recesses constitute keepers for
the rollers, and in such position of the parts it
will be apparent that the chair is elfectively and
rigidly held in operative position. In order to
fold the chair it is merely necessary to grasp the
back I in one hand and then move the seat 3
with the other hand upwardly toward the back,
whereupon the two rollers M will ride against
the lower side edges of the plates in until they
reach the registering recesses 9 and l2, where
upon the rollers will enter the latter as shown
in Fig. 5 thus positively holding the
folded position and against accidental

an edge
ing wear on the walls of the recesses i5, and
further act to assume all strains and stresses
to which the rollers I 4 may be subjected due
to the weight of the occupant of the chair. By
virtue of the grooves 8 being formed in the de
pending portions l at the sides of the seat it
will be seen that a greater bearing is afforded
for the rollers 14, thus adding to the stability
of the chair when in operative position. The
plates, in addition, act to reinforce and
strengthen the side rails ‘l of the seat and still
further act as abutments against which the
braces l5 may engage to thus prevent the latter
from engaging and consequently wearing away
the Wood or other non-metallic material of which
the depending members ‘i are generally formed.
It ‘is particularly to be noted that the instant
invention involves a minimum of parts that are
compactly assembled, and can be easily oper»
ated, and by virtue of the location of the braces
l5 and I7 closely adjacent to the front and rear
legs a more stabilized structure is provided and
one which maintains the chair at a maximum of
rigidity when in its operative position.
Obviously, the rollers‘ may be dispensed with,
if desired, but are preferably used to constitute
a part of the rod I3 in order to facilitate sliding
movement of the latter.
What is claimed is:
In a folding chair or like device, a back having
legs, a seat pivoted to the back and having de
pending members at its sides, each formed with
a longitudinal groove having substantially right
angular end parts, which latter extend toward
with the said end parts of the grooves, said
guide plate further having a side edge which
registers with the side wall of the groove adja
cent the seat, and against which edge the rollers
engage, a pair of braces at each end of the rod
having inner ends pivoted to the rod and having
outer ends pivoted to» the rear and front legs
respectively, and a sleeve on'the rod having
receivable in the end parts. of the latter, a guide
plate secured on the inside of each of the de
ends which engage the inner ends of the adja
cent braces and which hold the said inner ends 10
of the adjacent braces against the inner ends
of the other‘braces thereby to hold the latter
against the plates and to prevent sliding of the
pending members. and having downwardly open~
rollers on the rod.

10 rod extending transversely of the seat and having
rollers- onv its ends slidablle in the grooves and
15 ing recesses forming keepers to receive the rollers
at the ends of the rod, which recesses register
