Description




BACKGROUND OF THE INVENTION




1. Field of Invention




The present invention relates to the art of rocking chair and more particularly to a collapsible rocking chair intended for children.




2. Related Art




Conventionally, rocking chairs for children are classified as rocker supported rocking chairs and spring supported rocking chairs. A rocker supported rocking chair has a curved member on the bottom for allowing a rocking movement. As to spring supported rocking chairs, a number of prior art disclose such rocking chairs e.g., U.S. Pat. Nos. 4,553,768, 5,187,826, 5,269,591 and 5,503.458. Generally speaking, a spring supported rocking chair comprises a bottom frame, a seat frame and a back frame. The bottom frame disposes on the ground and a back frame connects to the bottom frame. The fabric covers on seat frame and back frame. Back frame keeps an angle or a distance with the bottom frame such that children seated or recumbent on the chair may rock up and down.




However, the previous designs suffered from a disadvantage. That is bottom frame. seat frame and back frame are affixed one another. It is understood that a considerable receiving space is required for such rocking chair when it is not in use. There is an improved detachable rocking chair available now. But it is unsatisfactory for the purpose for which the invention is concerned because the assembly and disassembly thereof are tedious.




Thus, it is desirable to provide a novel collapsible rocking chair in order to overcome the above drawbacks of prior art.




SUMMARY OF THE INVENTION




It is therefore an object of the present invention to provide a collapsible rocking chair. The collapsible rocking chair is collapsed to a compact storage position when it is not in use.




The collapsible rocking chair of the present invention is collapsed from an unfolded position for children to use to a folded position for storage. This collapsible rocking chair comprising an upper frame, a lower frame and a seat frame that pivotally mounted by pair of latches. In the unfolded position, rocking chair is adapted for children to sit or lie thereon. Upper frame, lower frame and seat are collapsed to a compact storage position by pivoting about latches when rocking chair is not in use.




Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.

DETAILED DESCRIPTION OF THE INVENTION




Referring to

FIGS. 1

,


2


, and


3


, there is shown a collapsible rocking chair constructed in accordance with the invention comprising an upper frame


10


, a lower frame


20


, a seat frame


30


and a pair of latches


40


,


40


′.




Upper frame


10


is generally a U-shaped metal tube having two ends


102


,


103


and forms a backrest


101


covered by a fabric pad


50


. Lower frame


20


is generally a U-shaped metal tube comprising two opposite bars


201


,


202


and a cross bar


203


connected one end of the two opposite bars


201


,


202


for sustaining on the ground. Two curved flexible portions


205


,


206


are extended from another end of the opposite bars


201


,


202


. Two attachment members


207


,


208


are extended from the flexible portions


205


,


206


. Seat frame


30


is also generally a U-shaped metal tube having two ends


302


,


303


and forms a seat portion


301


covered by a fabric pad


50


.




Note that latch


40


′ is a mirror image of latch


40


. Thus, only latch


40


is described below for the sake of brevity.




Referring to

FIG. 3

specifically, latch


40


comprises a first connection portion


401


having a hole


4011


and a second connection portion


402


having a tube member


4021


. A positioning member


4012


on the outer surface adjacent the hole


4011


whose two sides formed the two fixed positions and a stopping member


4013


on the inner surface. Referring to

FIG. 2

specifically, the attachment member


207


pivotally connects to the hole


4011


of the latches


40


by a pin


60


. The pin


60


inserts through the latch


40


to pivotally mount the seat frame


30


on reverse side of the first connection portion


401


. The two ends


102


.


103


of upper frame


10


inserts to the tube member


4021


of the second connection portion


402


. Such that rocking chair is configured to allow a child to sit or lie thereon. Also, lower frame


20


keeps an angle or a distance to upper frame


10


by the flexible portions


205


,


206


. The attachment member


207


is against the positioning member


4012


in the first fixed position and seat frame


30


is against the stopping member


4013


. As a result, referring to

FIG. 4A

the seated or recumbent child may rock up and down a little about the flexible portions


205


,


206


.




Referring to

FIG. 4B

, in collapsing the rocking chair, first fold seat frame


30


toward upper frame


10


with respect to latches


40


. Then fold lower frame


20


toward upper frame


10


with respect to pins


60


until the attachment members


207


is against positioning members


4012


in a second fixed position. Referring to

FIG. 4C

, finally fold seat frame


30


and lower frame


20


toward upper frame


10


, thus forming a compact rocking chair for facilitating storage.




It is found that upper frame


10


is not moved during collapsing since it is inserted in tube member


4021


and in a fixed relationship with respect to the latch


40


. As such, rocking chair is not collapsed to its minimum storage space. Accordingly, this second embodiment is provided as a modification of the first one aimed at changing the position of upper frame


10


during collapsing so as to fold the rocking chair in its minimum storage space when not in use. Referring, to

FIG. 5

, there is shown a latch


40


of collapsible rocking chair of a second preferred embodiment according to the invention.




A pivot base


404


, a cover


405


, and a press button


406


are provided on latch


40


. Pin


70


is inserted through tube member


4021


, cover


405


, press button


406


, and pivot base


404


. As such, cover


405


is pivot with respect to pivot base


404


about pin


70


. Press button


406


comprises a press member


4062


and a positioning member


4061


. Pivot base


404


has a center recess


4041


and two positioning channels


4042


,


4043


each communicating between the recess


4041


and the periphery of pivot base


404


. Cover


405


has an opening


4051


. In a configuration, positioning member


4061


is inserted into opening


4051


and positioning channel


4042


to reach recess


4041


, while press member


4062


is on the outside of opening


4051


. Also, spring


80


is anchored in positioning member


4061


for providing an elastic movement of the positioning member


4061


when it is activated.




Referring to

FIGS. 6A

,


6


B, and


7


, the collapsing operation of the

FIG. 5

rocking chair is now described. First, press down the press member


4062


to cause positioning member


4061


to clear positioning channel


4042


(i.e., first position) as shown in FIG.


6


A. Then rotate the press member


4062


to alien with the other positioning channel


4043


. At the same time, release the press member


4062


to cause positioning member


4061


to move upward into the other positioning channel


4043


. Thus, cover


405


is secured in this second position as shown in FIG.


6


B. As a result, upper frame


10


is moveable between first and second positions. Finally, perform a collapsing operation the same as that described above in the first embodiment. Thus, a collapsed rocking chair is obtained. As shown in

FIG. 7

, upper frame


10


is aligned with latch


40


as compared to the acute angle formed between upper frame


10


and latch


40


in FIG.


4


C. As an end, the rocking chair is collapsed to a more compact storage position.




The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
