Abstract

A collapsible and portable rocking chair includes left and right frame side assemblies collectively defining forward and rear leg portions, armrests, and back support members. The chair also includes cross-members connecting the left and right frame said assemblies and collectively defining a seat support in the set-up condition of the chair. The cross members are pivotally connected to one another as well as to the left and right frame side assemblies to facilitate folding of the chair frame to a collapsed condition. Each frame side assembly is supported on a fulcrum point for rocking movement of the chair frame. A rocker mechanism is attached to the chair frame to support the chair during rocking movement and to facilitate rocking of the chair in connection with the user'"'"'s shifting weight. The rocker mechanism may be provided in connection with a front leg member, a rear leg member, or both.

a pair of generally U-shaped cross members pivotally connected to one another for pivotal movement between an open condition wherein said cross members are disposed to generally resemble an X-shaped configuration and a closed condition wherein said cross members are disposed in generally parallel relationship with one another, said cross members collectively defining a seat support when in the open condition,

each cross member having its terminal ends pivotally secured to the front leg portion and the rear leg portion of one of the frame side assemblies;

a flexible seat panel mounted between the cross members and defining a generally taut seat when the cross members are in the open condition;

a fulcrum point supporting the chair frame and about which said chair frame can move between forward and rearward positions; and

at least one rocker mechanism attached to the chair frame for supporting the chair during movement of the chair frame between said forward and rearward positions;

wherein the open and closed conditions of the cross members generally correspond to the set-up and collapsed conditions of the chair.

2. The collapsible and portable rocking chair according to claim 1, wherein each frame side assembly maintains at least two contact points with the support surface on which it is set up.

3. The collapsible and portable rocking chair according to claim 1, wherein said rocker mechanism is attached to the rear of at least one of the frame side assemblies.

4. The collapsible and portable rocking chair according to claim 3, wherein said rocker mechanism comprises a tubular extension member projecting outwardly and downwardly from the rear of at least one of the frame side assemblies and received within a sleeve housing a spring to which the tubular member is attached.

5. The collapsible and portable rocking chair according to claim 4, further comprising a pair of static support runners connected to and supporting each frame side assembly via a fulcrum point associated with each said frame side assembly;

wherein the sleeve of the rocker mechanism is supported by at least one of said support runners.

6. The collapsible and portable rocking chair according to claim 1, wherein the rocker mechanism comprises a tubular extension member projecting outwardly and downwardly from the rear of each of the frame side assemblies and received within a respective sleeve pivotally mounted to a respective support runner, each sleeve housing a compression spring to which the respective tubular member is attached.

7. The collapsible and portable rocking chair according to claim 6, said support runner associated with each frame side assembly further defining first and second longitudinally spaced apart contact points;

and

said chair further comprising a third contact point associated with the lower end of the front leg portion of each frame side assembly;

wherein each frame side assembly contacts the support surface on which it is set up with at least two of the first, second and third contact points at all rocking positions of the chair.

8. The collapsible and portable rocking chair according to claim 1, wherein the rocker mechanism is attached to at least one of the front leg portion and the rear leg portion of each side frame assembly.

9. The collapsible and portable rocking chair according to claim 8, wherein the front leg portion includes a tubular front leg member and the rear leg portion includes a tubular rear leg member;

and

wherein the rocker mechanism comprises a sleeve associated with at least one of the front leg member and the rear leg member, said sleeve further housing a spring to which said leg member is connected.

10. The collapsible and portable rocking chair according to claim 1, wherein each cross member includes a front portion, a central front-back portion, and a rear portion, such that the front portions of the pair of cross members are pivotally connected at a front pivot point, the rear portions of the pair of cross members are pivotally connected at a rear pivot point, and the central front-back portions collectively define the seat support of the chair and receive the flexible seat panel therebetween for supported a seated user.

11. The collapsible and portable rocking chair according to claim 10, further comprising:

a forward support brace connected between the front portion of each cross member and the front leg portion of the frame side assembly to which the cross member is not pivotally connected at the terminal end thereof; and

a rear support brace connected between the rear portion of each cross member and the rear leg portion of said frame side assembly.

12. The collapsible and portable rocking chair according to claim 11, wherein at least one of the support braces includes an L-shaped slot that interacts with a pivot pin connecting said at least one support brace with one of the frame side assemblies.

13. The collapsible and portable rocking chair according to claim 1 further comprising a backrest support member connected to each frame side assembly;

and a flexible backrest support panel mounted between said backrest support members and defining a generally taut back support when the chair is in its set-up condition.

14. A collapsible and portable rocking chair comprising:

a chair frame comprising a pair of frame side assemblies having substantially mirrored construction and being relatively movable with respect to one another between a set-up condition of said chair where said frame side assemblies are transversely spaced apart from one another and a collapsed condition of said chair where said frame side assemblies are generally adjacent to one another, each frame side assembly including a front leg portion and a rear leg portion;

a fulcrum point supporting each frame side assembly and about which said chair frame can move between forward and rearward positions whereby the front and rear leg portions move relative to the support surface on which the chair is set up with movement of the chair frame about the fulcrum points;

a pair of generally U-shaped cross members pivotally connected to one another for pivotal movement between an open condition wherein said cross members are disposed to generally resemble an X-shaped configuration and a closed condition wherein said cross members are disposed in generally parallel relationship with one another, said cross members collectively defining a seat support when in the open condition,

each cross member having its terminal ends pivotally secured to the front leg portion and the rear leg portion of one of the frame side assemblies;

a flexible seat panel mounted between the cross members and defining a generally taut seat when the cross members are in the open condition;

a first foot associated with the front leg portion of each frame side assembly;

a second foot associated with the rear leg portion of each frame side assembly; and

a third foot associated with the fulcrum point of each frame side assembly;

wherein each frame side assembly contacts the support surface on which it is set up with at least two of the first, second and third feet at all positions between the forward and rearward positions of the chair frame.

15. The collapsible and portable rocking chair according to claim 14, further comprising at least one rocker mechanism attached to the chair frame for supporting the chair during movement of the chair frame between the forward and rearward positions.
