PATENT OFFICE ‘ v
FOLDING CHAIR
Harland 0. Mearkle, Sharon Hill, Pa., assignor to
Philadelphia Screen Mfg. Company, Philadel
phia, Pa., a corporation of Pennsylvania
Application March ‘29, 1937, Serial No. ream
2 Claims. (Cl. 155-439)
al:
This invention relates to new and useful im
nected thereto by means of links I40 pivoted ad
provements in folding chairs and more particu
jacent their opposite ends to said rear uprights
larly to folding chairs having a back support l and rear legs 9 respectively.
which may be adjusted from an upright or sitting
The seat frame is supported at the rear of the
position to an angular or reclining position and chair by means of abrace or strut“ which con 5
vice versa.
nects between the rear uprights .‘l, the side ‘frame
The present invention comprehends a folding members 3 of said seat frame merely rest upon,
adjustable backarm-chair which may be folded said strut or brace II and haveino positive or
. .or set up by a single relative movement of its
10 component parts and which when folded oc
cupies a minimum amount of space.
Another object of the invention is to provide
a chair of the character'set forth having novel
means for effecting adjustment of the back sup
15 port at will.
A further feature of the invention resides in
the comparatively simple construction of the
chair, the economy with which it may be pro
duced and the ease with which it may bet set up
20 or folded and adjusted.
These and other objects and features of the
invention and the details of construction there
of are set forth hereinafter and shown in the
accompanying drawings, in which:
Figure 1_ is a view in perspective of a folding
adjustable back arm-chair made in accordance
with this invention;
-
Figure 2 is a detached fragmentary view in
perspective illustrating certain structural de
30 tails of the chair;
Figure 3 is a view in section vertically through
the chair, and
Figure 4 is a diagrammatic fragmentary view
illustrating the positions and movement of the
back support and associated elements when ad
justed from reclining to sitting position.
‘Referring more particularly to the drawings,
reference numeral I designates a pair of front
legs which are connected together adjacent their
other connection therewith. A front transverse,“v
member '12 connects the forward ends of the side
ends of said side members 3, this rear member
l3 being located rearwardly of the uprights ‘I
and provided with laterally projecting portions 15
or elements I 4 at opposite ends thereof which
extend into the path of said uprights ‘l and func
tion as supports therefor when the chair is set
up» as shown in Figure 1 of the drawings,
A back‘ support having side and top frame 20
members l5 and I6 respectively is pivotally con
nected adjacent the lower ends of said side frame
members . l5 to the side members 3 of the seat
frame as indicated by reference numeral l1 and
these same side frame members l5 are‘ further 25
connected to the upper ends of the uprights ‘l
by means of links l8 pivoted at their opposite
ends to said uprights ‘l and side frame members
I5 respectively as at 8 and I 9 to permit said
back support to be adjusted to either a reclining 30'
or sitting (upright) position with respect to the
seat frame and chair structure.
To adjust the back support from say, for ex
ample, reclining to sitting (upright) position,
the back structure including the side frame mem 35
bers I5 is lifted or raised upwardly, carrying
with it the seat frame which is raised from its
position of rest upon the brace or strut H to
the position shown in dot and dash lines in Fig
40 lower or bottom ends by means of a strut or
ure 4 of the drawings, and causing the uprights ‘l
brace 2. The front legs I are pivotally con
nected to the side frame members 3 of the seat
frame outwardly thereof as indicated by refer
ence numeral 4, and the upper extremities of
45 said front legs I are pivotally connected as at
5 to arm rails 6 which are in turn pivoted to rear
side upright members 1 as indicated at 8.
A pair of rear legs 9 have their upper forward
to approach a vertical position likewise shown in
dot and dash lines in said Figure 4. As these
ends pivotally connected to the front legs I by
the previously mentioned means indicated by
reference numeral 4 and these rear legs 9 de
cline rearwardly of the chair a su?icient dis
tance to give a broad ?rm support thereto and
also to support the rear side uprights ‘l the lower
55 ends of which rest upon said legs 9 and are con
10.
members 3 of the seat frame and a rear trans
verse member |3 connects between the rearward
elements of the chair assume the aforementioned
relative positions, the back support and its links
l8 are swung in a clockwise direction with re
45
spect to the drawings about the pivot 8 to a posi
tion forwardly of the uprights 1 until the seat
frame again resumes its position upon the strut
H and the uprights ‘I assume their normal posi
tion shown in solid or full lines in Figure 4, the
back support and links [8 ultimately assuming
the position shown in dot and dash‘ lines in Fig
ure 3, and in dotted lines in Figure 4. The same
operation takes ‘place when adjusting the back
support from sitting or upright position to re

support and links 18 are swung in a counterclock
wise or rearward direction with respect to the
chair is folded, opening or setting up thereof is
a transverse element connecting the uprights, a
back support structure, a seat structure pivotally
connected to the front legs and said back support
structure arranged to rest upon said transverse
element for support when the chair is set up, and
other members adjustably connecting the back
structure and the rear uprights to permit the
former to be swung relative to the latter between 10
two positions disposed respectively at an angle
to each other and said seat structure.
2. In a folding chair, a pair of front legs, a
accomplished by grasping said members l2 and
pair of rearwardly declining rear legs pivotally
?gures in the drawings.
In use with the chair in a set-up position, as
shown in Figure 1 of the drawings, when it is de
sired to collapse or fold the same, it is merely nec
essary to grasp the front transverse member l2
of the seat frame and the top frame member N3 of
10 the back support structure and swing or pivot
these members and their associated structure to
ward one another. In similar manner, when the

sociated structure as far as possible, the primary
folding action taking place about the pivots I‘! in
both the folding and setting-up operations.
While a particular embodiment of the inven
20 tion has been set forth herein for descriptive pur
poses, it is not intended that said invention shall
be precisely limited thereto but that modi?cations
and changes may be incorporated and embodied
therein within the scope of the annexed claims.

nected to the front legs and uprights, members
movably connecting said uprights and rear legs,
I claim:
.
1. In a folding chair, a. pair of front legs, a pair
of rearwardly declining rear legs pivotally con
nected to said front legs, a. pair of rear uprights
,arrangedto rest upon said rear legs for support
30 when the chair is set up, arm rests pivotally con
connected to said front legs, a pair of rear up
rights arranged to rest upon said rear legs for
support when the chair is set up, arm rests piv
otally connected to the front legs and uprights,
members movably connecting said uprights and
rear legs, a back support structure, a seat struc
ture pivotally connected to the front legs and said
back support structure, means for supporting the
rear of said seat structure when the chair is set
up, and other members adjustably connecting the
back structure and the rear uprights to permit .
the former to be swung relative to the latter be
tween two positions disposed respectively at an
angle to each other and said seat structure.
