FOLDING CHAIR AND TABLE SET
Abstract
A folding chair and table set in which the chairs individually
fold for storage under the table. Each chair is individually
attached to the table and can be moved about a central pivot for
the comfort of the user. The folding of the chairs reduces the
distance from the front legs to the back legs of the chair and in
addition reduces the overall height of the chair to permit it to be
stored under the table top without raising the top.

Claims
What is claimed is:
1. A combination folding chair and table set comprising a generally
flat base, a plurality of table legs secured to and extending
upwardly from said base, a table top mounted on the upper ends of
said table legs, a folding chair including a back member, a seat
hingedly secured to said back member for folding upwardly into
engagement with said back member, a pair of front legs hingedly
secured to the under side of the forward edge of said seat member,
a first one piece arm means extending between said back member and
said front legs for normally maintaining said chair in erect
position, a second one piece means slidably connected to said first

consecutive transverse directions with said first means upon
folding the chair from its normally erect position, and folding
means for securing said chair to said base member.
2. A device as claimed in claim 1 wherein the folding means
securing said chair to said base member is longitudinally
adjustable to permit the adjustment of the space between the chair
in erected position and the table.
3. A device as claimed in claim 1 wherein the folding means
connecting said chair to said base member is mounted to said base
member for pivotal movement about a vertical pivot.
4. A device as claimed in claim 1 wherein the folding means
connecting said chair to said base member is hingedly secured to
said base member to permit said folding means to fold upwardly
about a horizontal pivot as said chair is moved to storage position
underlying said table top.
5. A device as claimed in claim 1 wherein said folding means for
connecting said chair to said base includes a guide slot and tongue
slidingly mounted in said guide slot for permitting longitudinal

respect to said table with said chair in erected position.
Description
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to folding chair and table sets of
the type disclosed in my prior U.S. Pat. No. 2539603, issued Jan.
30, 1951.
SUMMARY OF THE INVENTION
A folding chair and table set is provided in which the front legs
and seat are folded up against the back of the chair and the lower
leg portions of the back are folded to reduce the overall height of
the folded chair. The folding chair is attached to the table and
when folded engages under the top of the table for storage.
The primary object of the invention is to provide a folding chair
and table set which permits the chairs to be folded into compact
units, stored under the table top when out of use.
Other objects and advantages will become apparent in the following
specification when considered in the light of the attached
drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a side elevation of the invention;
FIG. 2 is a fragmentary horizontal sectional view taken along the
line 2--2 of FIG. 1 looking the direction of the arrows with parts
broken away for convenience of illustration;
FIG. 3 is an enlarged fragmentary side elevation of one of the
chair units in erected position shown in dotted lines in folded
position with parts broken away and in section for convenience of
illustration;
FIG. 4 is a fragmentary top plan view of a detail of the
invention;
FIG. 5 is an enlarged fragmentary transverse cross section taken
along the line 5--5 of FIG. 4 looking in the direction of the
arrows;
FIG. 6 is an enlarged fragmentary side elevation of the central
pivot and hinge structure;
FIG. 7 is a vertical sectional view of the table illustrating the
stored chairs in folded condition; and
FIG. 8 is a fragmentary top plan view of the chairs in their
unfolded position of use attached to the table.
DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to the drawings in detail wherein like reference
characters indicate like parts throughout the several figures, the
reference numeral 10 indicates generally a folding chair and table
set constructed in accordance with the invention.
The set 10 includes a table generally indicated at 11, having a
generally rectangular base 12, a generally rectangular top 13 and a
plurality of upright legs 14 which extend between and connect the
top 13 to the base 12.
A plurality of folding chairs generally indicated at 15 are secured
to the table 11 to form a folding chair and table set 10.
Each of the folding chairs 15 include a back member 16 having a
cross bar 17 extending transversely intermediate the upper and
lower ends thereof. A seat 18 is connected to the bar 17 by a hinge
19 to permit the seat 18 to be folded against the back member 16 as
can be seen in FIG. 3. Leg extensions 20 are secured to the lower
end of the back member 16 by hinges 21. Front legs 22 are secured
to the front corners of the seat 18 by hinges 23 so that the legs
22 can fold against the bottom of the seat 18 when the chair 15 is
in its folded position. An arcuate arm 24 is connected to the legs
extension 20 by a pivot pin 25 and has its opposite end connected
to the underside of the seat 18 by a hinge 26. An arcuate brace 27
is pivotally connected to the back member 16 by a pivot pin 28 and
has an L-shaped slot 29 formed in its outer end which slidably and
pivotally engages a pivot pin 30 extending through the arm 24. A
brace 31 is pivotally secured to the front leg 22 by a pivot pin 32
and is pivotally carried at its rear end by the pivot pin 30.
A bar 33 is secured to the leg extension 20 by a hinge 34 and
extends horizontally therefrom with the chair 15 in erect position
ready for use. The bar 33 carries a longitudinally slotted plate 35
on its outer end and is provided with a grooved slot 36 to receive
a sliding tongue 37 positioned therebetween. A pin 38 extends
through the end of the tongue 37 and the slotted plate 35 to secure
the tongue 37 to the bar 33. A bar 39 is integrally formed with the
tongue 37 and extends to a recessed hinge 40 as can be seen in FIG.
3. An arm 41 is connected to the recessed hinge 40 and extends in
aligned relation to the bar 39 terminating at a bracket indicated
generally at 42 secured to the base 12. The bracket 42 has a lower
hinge leaf 43 secured to the base 12 by screws 44 and has a
transversely extending pintle 45 connected therewith. An upper leaf
46 is secured to the lower leaf 43 by the pintle 45 and has a
bracket plate 47 mounted thereon by a vertical pivot pin 48.
L-shaped guide members 49 are secured to the upper leaf 46 to
overlie the bracket plate 47 and guide it in its rotational
movement about the pivot pin 48. The arm 41 is secured to a leaf 50
which in turn is mounted on the bracket plate 47 by a
longitudinally extending pivot pin 51. The bracket 42 permits the
arm 41 to hinge upwardly to the dotted line position illustrated in
FIG. 6, to move from side-to-side about the pivot pin 48 and to
rotate on its own longitudinal axis about the pivot pin 51.
A handle 52 is mounted on the back 16 of each of the chairs 15 to
be grasped by the user when removing the chair from its folded
storage position beneath the table 11. The chair 15 can be swung
from side to side on the arm 41 and can be slid in and out by
sliding the bar 33 on the tongue 37 to vary the distance of the
chair from the table when in use. The chair 15 can be folded by
raising the seat 18 against the back member 16 by first lifting the
arm 27 to unlock the L-shaped slot 29 from the pivot pin 30. In
folding the chair 15 the seat 18 is raised against the back 16 and
then the arm 41 is raised, with the chair 15 being simultaneously
moved inwardly to rest upon the base 12 in the position illustrated
in FIG. 7.
Having thus described the preferred embodiment of the invention it
should be understood that numerous structural modifications and
adaptations may be resorted to without departing from the spirit of
the invention.
