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.
