William R. McGowen, Pittsburgh, Pa., assignor
to, The-McKay Company, Pittsburgh, Pa., a
corporation of Pennsylvania.
Application June 26, 1937, Serial No. 150,457
6 Claims. (01.155-178)
My invention relates to chairs or similar ‘seat
an essential'part of the present invention. A
ing structures, and has for its object the provi
sion of a‘ structure of such form that the seat
boardiB forms part of the cushion structure, and
and back cushions or the like can readily be
assembled in the chair frame, with a minimum
Ea amount of labor and with the use of a minimum
number of attaching or holding elements, and
wherein the cushion elements or the like can
readily be removed for repairs and replacement.
1O
Some of the forms which my invention may
take are shown in the accompanying drawing
wherein Figure 1 is a perspective view of the
chair structure embodying one form of my in
vention; Fig. 2 is a fragmentary back view there
15 of; Fig. 3 is a view on on enlarged scale taken
'
on the line III-III of Fig. 1; Fig. 4 is a view '
showing a modi?cation of the structure of Fig. 3,
and Fig. 5 shows still another modi?cation.
Referring?rst to Figs. 1 to 3,1, show a tubular
_
20 metal member bent to form base bar portions 6,
legs 1, and arm rests 8. The rear ends of the
arm rest portions are ?attened at 9 for attach
ment by screws to a back rest 10.
‘
A metal channel of elongated loop form is bent
25 to form seat bars II and back bars I2, the seat
bars having a cross-connecting portion 13 and
the backbar elements a cross-connecting portion
I4. The seat bar portions H are secured in any
suitable manner to the leg portions 1, as by
30 welding, riveting, or by bolts. The ?attened ends
9 of the arm rests may be welded to the back bar
portions l2, if desired.
may be of suitable material, such as a single
board, but is here shown as a laminated board.
As above indicated, the board l9 will project at
its upper and side edges, as indicated at 20, to
?t within the channel member. A covering strip
I8‘ of cloth-like material partially embraces the
board I9 and is tacked thereto.
The channel bar above referred to is'made of 10
spring-like material so that the side bar portions
thereof can be sprung apart to permit insertion
of the flanges of the back elements into the chan
nel. In placing the backelement H) in place, it
is ?rst set low in the frame and after the bar 15
portions I I and I2 have been permitted to spring
back into place and cause engagement with the
.?anges 2|], the member llliis slid upwardly to
the position shown in Fig. 1, and there detach
ably held in place as by screws 2|.
Similarly, the seat element I5 will be inserted
her and slid forwardly until its front ?ange seats
within the portion l3 of the channel.
‘ While the covering 18 is tacked to the board 25
19, the channel portions l2 and I4 closely em
brace the edges of the cover and assist in holding
it‘ securely in place as well as serving as a ?nish
strip for such edges.
Referring now to Fig. 4, I show a structure 30
which can be used with the metal frame elements
of Fig. 1, but wherein the seat and back cush
My invention is more particularly concerned
with the form of connection between the back
rest I!) and the seat board or cushion l5. These
35 two members are of practically identical con
struction, and the description of the back cush~
ion 1.0 will apply also to the seating element l5.
‘The members 10 and I5 may be upholstered or
not, as may be desired. _In any event, they are
each provided on three sides with ledge-like pro
ions are of somewhat different form. In this
structure a cushion board 22 has nailed thereto
jections that serve as ?anges or beads that ?t
ing material 25 is secured to the members 23 to
into the channel above described. Thus, the back
rest It! has its uppermost ?ange ?tting within
45 the portion M of the channel and its side ?anges
?tting within the portions l2 of the channel.
Similarly, the front edge of the seat element 15
?ts within the cross bar portion l3, and its side
give a ?nished appearance to the rear side of
the cushion.

nel.

‘
i
The back rest is hereshown as upholstered,
and provided with an inner frame I‘! which is
formed of wood, and of, rectangular form to
sti?en and maintain the cushion in proper shape
‘1; and contour at its edges. The frame I‘! is not
20
at a point rearwardly in the channel frame mem
along each of three of its edges a bar 23 that
extends outwardly from the edges of the cush
ion proper to form projecting‘?anges that ?t'into
the channel bar, as in the case of the ?ange
portion 20 of Fig. 3. The upholstery covering
24 in addition to being tacked to the board 22, is 40
clamped between the members 22 and 23. - Cover
As shown in Fig. 5,‘ the cushion element is 45
provided with a base board 26 which corresponds
to the boards l9 and 22 of the other ?gures, but
in this case a marginal ?ange is provided at
three edges of the board 26 by strips 21 which
are nailed to the board 26 and which ?t within
the ?ange bar as in the other ?gures.

I claim as my invention:
1. Chair structure comprising a base portion
and seat and back members carried thereby, the
said members including a channel frame member 55
2
2,121,130
of elongated loop form the sides whereof are bent
intermediate their ends to form seat and back
bar portions, and being laterally yieldable, and
seat and back cushions or the like having their
side edges insertible into the channels of the seat
and back bar portions when such portions are
sprung apart.
'
2. Chair structure comprising a base portion
and seat and back members carried thereby, the
10 said members including a channel frame member
of elongated loop form the sides whereof are bent
intermediate their ends to form‘ seat and back
bar portions, and being laterally yieldable, and
seat and back cushions or the like having their
15 side edges insertible into the channels of the seat
and back bar portions, at points adjacent to the
bends, when such portions are sprung apart,
each cushion being slidable in the channels to

3. Chair structure comprising a base portion
and seat and back members carried thereby, the
said members including a channel frame member

apart, and arm rest members extending upwardly
and rearwardly from the forward part of the base
and having their rear ends secured to the back
cushion and to the back bars.

5. Chair structure comprising a base portion
and seat and back members carried thereby, the
said members including a channel frame member
of elongated loop form the sides whereof are bent
intermediate their ends to form seat and back 15
bar portions, and being laterally yieldable, and
a cushion or the like having its side edges in
sertible into the channels at points adjacent to
the bends, when the members are sprung apart,
and being slidable therein to permit an end edge 20

edges insertible into the channels of the seat and
back bar portions when such portions are sprung
apart, and arm rest members extending upwardly
and'rearwardly from the forward part of the base

cushion.
4. Chair structure comprising a base portion
and-seat and back members carried thereby, the
