Abstract

A rocking chair includes a base, an elastic member, a seat, and a back joined to the seat; the elastic member connected to the base at a lower end thereof, and it is made in such a way as to be capable of rocking in any desired direction; the seat is connected to an upper end of the elastic member such that it can rock together with the elastic member while the base is still; the seat further can turn on the elastic member; the base has a rear extension portion, which is right under the back such that the chair will be steady when the seat is rocking.

Description

BACKGROUND OF THE INVENTION

1. Field of the invention
The present invention relates to a rocking chair, more particularly one, which is made in such a way that the base will stand still while the seat is rocking, and that the seat can be rocked in any direction according to the sitter's need.
2. Brief Description of the Prior Art
Referring to FIG. 1, a conventional rocking chair 10 includes a back 101, a seat 102 joined to the back 101, four supporting legs 104 connected to the seat 102, armrests 103 connected to upper ends of the supporting legs 104, and curved bars 105 connected to-lower ends of the supporting legs 104 for allowing the chair 10 to rock.
The rocking chair 10 can only be rocked forwards and backwards, and the sitter has to stand up and move the chair if he wants to make the chair face in another direction. Therefore, the rocking chair 10 has relatively limited functions, and it isn't convenient to use.

SUMMARY OF THE INVENTION

It is a main object of the present invention to provide an improvement on a rocking chair, which is more convenient to use than the conventional one.
The rocking chair of the present invention includes a base, an elastic member, a seat, and a back joined to the seat. The elastic member is connected to the base at a lower end thereof, and it is made in such a way as to be capable of rocking in any desired direction. The seat is connected to an upper end of the elastic member such that it can rock together with the elastic member. Consequently, while seated in the chair, one can rock the seat in any direction according to his need. The seat further can turn on the elastic member. The base has a rear extension portion, which is right under the back such that the chair will be steady when the seat is being rocked.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a perspective view of a conventional rocking chair,
FIG. 2 is a perspective view of the rocking chair according to the present invention,
FIG. 3 is a front view of the rocking chair of the present invention,
FIG. 4 is a top view of the rocking chair of the invention,
FIG. 5 is a partial top view of the locating mechanism of the seat of the rocking chair according to the present invention, and
FIG. 6 is a partial vertical section of the present rocking chair.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 2 to 6, a preferred embodiment 1 of a rocking chair includes a seat 11, a back 111 securely connected to the seat 11, an elastic member 12, and a base 13.
The base 13 has a substantially oval shape, and it has a rear extension portion 131.
The base 13 has a substantially oval shape, and it has a rear extension portion 131, and a connecting portion in front of the rear extension portion 131.
The elastic member 12 is connected to the connecting portion of the base 13 at a lower end thereof such that it can rock when external force is exerted thereon. Furthermore, the elastic member 12 has an uppermost disk part (not numbered) at an upper end, which is formed with three locating cavities 121 near to the edge on the upper side thereof; the locating cavities 121 include a middle rear one, and left and right ones in front of and on two sides of the rear one. Furthermore, the disk part is formed with two stopping protrusions 122 on the upper side, which are next to the left and the right locating cavities 121 respectively.
The seat 11 is connected to a middle portion of the uppermost disk part of the elastic member 12 at a center of gravity thereof such that it can turn on the elastic member 12, and such that the extension portion 131 of the base 13 is right under the back 111. Therefore, the seat 11 can be made to rock in any direction together with the elastic member 12 according to the sitter's need. In addition, a locating unit 112 is arranged on a lower side of the seat 11 for preventing the seat 11 from turning, which locating unit 112 includes a pin 113, and a spring connected to the pin 113 for making the pin 113 downwards stick out from- the unit 112 and into a selected one of the locating cavities 121 of the uppermost disk part of the elastic member 12.
Therefore, the seat 11 can be turned within a certain range, which is defined by the two stopping protrusions 122 of the uppermost disk part of the elastic member 12, and the pin 113 of the locating unit 112 will pass into one of the cavities 121 to help locate the seat 11 after the seat 11 has been turned to face in a new direction. And, because of the elastic member 12, the user can rock the seat 11 in any desired direction.
From the above description, it can be easily understood that the rocking chair of the present invention has advantages as followings:
1. The present rocking chair has a simpler structure and few parts than the conventional one, and it is easy to assemble.
2. While seated in the chair, the user can rock the seat in any direction according to his need.
3. The seat 11 of the rocking chair can be turned on the elastic member 12 therefore the sitter doesn't have to stand up and move the whole chair to face in a different direction, and the chair is convenient to use.
4. The substantially oval base 13 has the extension portion 131, which is right under the back 111, therefore the chair will be steady when the seat is rocking.

Claims
