Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a foldable chair assembly,
and more particularly to a foldable chair assembly that is folded
and expanded easily and conveniently, thereby facilitating the user
using the foldable chair assembly.
[0003] 2. Description of the Related Art
[0004] A conventional chair has a fixed size and cannot be folded,
thereby occupying larger space when not in use. The foldable chair
can be expanded 10 when in use and can be folded when not in use so
as to save the space, thereby facilitating the user storing the
conventional foldable chair. However, the conventional foldable
chair tends to be folded unintentionally, thereby causing danger to
the user.
SUMMARY OF THE INVENTION

a foldable chair assembly that is folded and expanded easily and
conveniently, thereby facilitating the user using the foldable
chair assembly.
[0006] Another objective of the present invention is to provide a
foldable chair assembly, wherein when the foldable chair assembly
is disposed at the normally stretched state, each of the two
resting members is located above an intersection between the first
support leg and the second support leg, and the bent portion of
each of the two resting members is directed upward.
[0007] A further objective of the present invention is to provide a
foldable hair assembly, wherein when the foldable chair assembly is
disposed at the normally stretched state, the limit rod of the
first support leg is rested on the mediate portion of the second
support leg, so that the first support leg is combined with the
second support leg so as to support the support frame and the seat
rigidly and stably.
[0008] A further objective of the present invention is to provide a
foldable chair assembly, wherein when the foldable chair assembly
is disposed at the folded state, each of the two resting members is
located below an intersection between the first support leg and the
second support leg, and the bent portion of each of the two resting
members is directed downward.
[0009] In accordance with the present invention, there is provided
a foldable chair assembly, comprising:
[0010] a support frame;
[0011] a first support leg having an upper portion pivotally
mounted on a bottom of the support frame;
[0012] a second support leg having an upper portion pivotally
mounted on the bottom of the support frame; and
[0013] two opposite resting members each pivotally mounted between
a mediate portion of the first support leg and a mediate portion of
the second support leg.
[0014] Further benefits and advantages of the present invention
will become apparent after a careful reading of the detailed
description with appropriate reference to the accompanying
drawings.

DETAILED DESCRIPTION OF THE INVENTION
[0028] Referring to the drawings and initially to FIGS. 1-4, a
foldable chair assembly 7 in accordance with the preferred
embodiment of the present invention comprises a support frame 5, a
first support leg 1 having an upper portion pivotally mounted on a
bottom of the support frame 5, a second support leg 2 having an
upper portion pivotally mounted on the bottom of the support frame
5, and two opposite resting members 3 each pivotally mounted
between a mediate portion of the first support leg 1 and a mediate
portion of the second support leg 2. Preferably, each of the first
support leg 1 and the second support leg 2 is substantially
U-shaped.
[0029] The bottom of the support frame 5 is provided with a
plurality of pivot ears 51 for pivoting the upper portion of each
of the first support leg 1 and the second support leg 2 by a
plurality of pivot pins 52. The foldable chair assembly 7 further
comprises a seat 6 mounted on the support frame 5.
[0030] As shown in FIGS. 2A and 2B, each of the two resting members
3 is substantially V-shaped and has a first end pivotally mounted
on an inner side of the first support leg 1 by a first pin 4 and a
second end pivotally mounted on an outer side of the second support
leg 2 by a second pin 41. In addition, the mediate portion of the
first support leg 1 is provided with a limit rod 11 rested on the
mediate portion of the second support leg 2. Preferably, the limit
rod 11 of the first support leg 1 is located above the first pin 4
at the first end of each of the two resting members 3.
[0031] As shown in FIGS. 2 and 4, each of the two resting members 3
has a mediate portion formed with a bent portion 30 facing upward
and directed toward the upper portion of the first support leg
1.
[0032] Referring to FIGS. 4-7 with reference to FIGS. 1-3, when the
user wishes to fold the foldable chair assembly 7, the limit rod 11
of the first support leg 1 is rested on the mediate portion of the
second support leg 2 as shown in FIG. 4, so that the first support
leg 1 is combined with the second support leg 2 so as to support
the support frame 5 and the seat 6 rigidly and stably. Then, the
support frame 5 is pulled upward to move the first support leg 1
upward, so that the first support leg 1 and the limit rod 11 are
moved upward and each of the two resting members 3 are pivoted
about the second pin 41 in the counterclockwise direction to move
from the position as shown in FIG. 4 to the position as shown in
FIG. 5. Then, the support frame 5 is pushed downward to move the
first support leg 1 downward, so that the first support leg 1 and
the limit rod 11 are moved downward and each of the two resting
members 3 are pivoted about the second pin 41 in the
counterclockwise direction to move from the position as shown in
FIG. 5 to the position as shown in FIG. 6. At this time, each of
the two resting members 3 is located below an intersection between
the first support leg 1 and the second support leg 2 and is
directed downward. Then, the support frame 5 is pushed downward
successively to move the first support leg 1 downward, so that the
first support leg 1 and the second support leg 2 are pressed toward
each other and are folded below the support frame 5 as shown in
FIG. 7, thereby folding the foldable chair assembly 7.
[0033] Referring to FIGS. 8-11 with reference to FIGS. 1-7, when
the user wishes to expand the foldable chair assembly 7, the
support frame 5 is pulled upward to move the first support leg 1
upward, so that the first support leg 1 and the limit rod 11 are
moved upward and each of the two resting members 3 are pivoted
about the second pin 41 in the clockwise direction to move from the
position as shown in FIGS. 8 and 9 to the position as shown in FIG.
10. At this time, each of the two resting members 3 is located
above an intersection between the first support leg 1 and the
second support leg 2 and is directed upward. Then, the support
frame 5 is pushed downward to move the first 20 support leg 1
downward, so that the first support leg 1 and the limit rod 11 are
moved downward and each of the two resting members 3 are pivoted
about the second pin 41 in the clockwise direction to move from the
position as shown in FIG. 10 to the position as shown in FIG. 11,
where the limit rod 11 of the first support leg 1 is rested on the
mediate portion of the second support leg 2, thereby expanding the
foldable chair assembly 7 as shown in FIG. 11. Thus, the first
support leg 1 is combined with the second support leg 2 so as to
support the support frame 5 and the seat 6 rigidly and stably.
[0034] Accordingly, when the foldable chair assembly 7 is disposed
at the normally stretched state, each of the two resting members 3
is located above an intersection between the first support leg 1
and the second support leg 2, and the bent portion 30 of each of
the two resting members 3 is directed upward. In addition, when the
foldable chair assembly 7 is disposed at the folded state, each of
the two resting members 3 is located below an intersection between
the first support leg 1 and the second support leg 2, and the bent
portion 30 of each of the two resting members 3 is directed
downward. Further, when the foldable chair assembly 7 is disposed
at the normally stretched state, the limit rod 11 of the first
support leg 1 is rested on the mediate portion of the second
support leg 2, so that the first support leg 1 is combined with the
second support leg 2 so as to support the support frame 5 and the
seat 6 rigidly and stably. Further, the foldable chair assembly 7
can be folded and expanded easily and conveniently, thereby
facilitating the user using the foldable chair assembly 7.
[0035] Although the invention has been explained in relation to its
preferred embodiment(s) as mentioned above, it is to be understood
that many other possible modifications and variations can be made
without departing from the scope of the present invention. It is,
therefore, contemplated that the appended claim or claims will
cover such modifications and variations that fall within the true
scope of the invention.
