DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
FIGS. 3 and 7
illustrate a foldable rocking chair
3
embodying this invention. The chair
3
includes: parallel first left and right support rods
31
of equal lengths and having first top and bottom ends
313
,
317
; a first cross rod
312
interconnecting the first top ends
313
of the first left and right support rods
31
; parallel second left and right support rods
32
of equal lengths and respectively associated with the first left and right support rods
31
and having second top and bottom ends
323
,
327
, each of the second left and right support rods
32
crossing a respective one of the first left and right support rods
31
so as to define an intersection (indicated as reference character “X” in
FIG. 3
) therebetween and so as to divide the respective one of the first left and right support rods
31
into first front and rear sections
314
,
311
relative to the intersection (X) and so as to divide each of the second left and right support rods
32
into second front and rear sections
326
,
321
relative to the intersection (X), the first front section
314
extending downwardly from the intersection (X) to the first bottom end
317
, the first rear section
311
extending upwardly from the intersection (X) to the first top end
313
, the second front section
326
extending upwardly from the intersection (X) to the second top end
327
, the second rear section
321
extending downwardly from the intersection (X) to the second bottom end
323
; a second cross rod
322
interconnecting the second bottom ends
323
of the second left and right support rods
32
and having a length greater than that of the first cross rod
312
; a left stretcher
34
, in the form of a rod, that is disposed between the first and second left support rods
31
,
32
and that has two opposite ends
341
,
342
respectively pivoted on the first front section
314
of the first left support rod
31
and the second rear section
321
of the second left support rod
32
; a right stretcher
34
, in the form of a rod, that is disposed between the first and second right support rods
31
,
32
and that has two opposite ends
341
,
342
respectively pivoted on the first front section
314
of the first right support rod
31
and the second rear section
321
of the second right support rod
32
; an L-shaped left arm support
36
, in the form of an L-shaped rod, that is disposed above the left stretcher
34
and having a first end
361
pivoted on the first rear section
311
of the first left support rod
31
, and a second end
362
pivoted on the second front section
326
of the second left support rod
32
; an L-shaped right arm support
36
, in the form of an L-shaped rod, that is disposed above the right stretcher
34
and having a first end
361
pivoted on the first rear section
311
of the first right support rod
31
, and a second end
362
pivoted on the second front section
326
of the second right support rod
32
; a cross member including a pair of juxtaposed rods
324
,
325
that interconnect the second front sections
326
of the second left and right support rods
32
and that are disposed adjacent to the second top ends
327
of the second left and right support rods
32
; a flexible mat
33
, such as a canvas sheet, having two opposite ends
332
,
331
respectively secured to the first cross rod
312
and the cross member and extending between the first left and right support rods
31
; a stop member
35
, in the form of a rod, that is mounted on the first front sections
314
of the first left and right support rods
31
below the second front sections
326
of the second left and right support rods
32
for limiting downward movement of the second front sections
326
of the second left and right support rods
32
upon rotation of the second left and right support rods
32
relative to the left and right stretchers
34
when an external downward force is applied on the second front sections
326
of the second left and right support rods
32
via the cross member; and a U-shaped rod
39
having two opposite ends
391
respectively connected to the second top ends
327
of the second left and right support rods
32
. An elastic member
37
is sleeved on each of the opposite ends of the stop member
35
underneath the second front section
326
of a respective one of the second left and right support rods
32
so as to provide a cushioning effect when the second front sections
326
of the second left and right support rods are brought into contact with the stop member
35
.
As illustrated in
FIG. 4
, the foldable rocking chair
3
can be rocked back and forth. When an external force is applied on the top portion
333
of the mat
33
, the first left and right support rods
31
will turn rearwardly and downwardly relative to the left and right stretchers
34
, which, in turn, will pull the second left and right support rods
32
to turn rearwardly and upwardly relative to the left and right stretchers
34
via the left and right arm supports
36
, and when an external force is applied on the bottom portion
334
of the mat
33
, the second left and right support rods
32
will turn frontwardly and downwardly relative to the left and right stretchers
34
, which, in turn, will pull the first left and right support rods
31
to turn frontwardly and upwardly relative to the left and right stretchers
34
via the left and right arm supports
36
.
Preferably, the second cross rod
322
is substantially flush with the first cross rod
312
when the chair
3
is in an extended condition so as to enhance the stability of the chair
3
.
As illustrated in
FIGS. 5 and 6
, the chair
3
can be simply folded by pushing the first rear sections
311
of the first left and right support rods
31
and the second front sections
326
of the second left and right support rods
32
toward each other to turn the first left and right support rods
31
and the second left and right support rods
32
relative to the left and right stretchers
34
.
With the invention thus explained, it is apparent that various modifications can be made without departing from the spirit of the present invention. It is therefore intended that the invention be limited only as recited in the appended claims.
