Collapsible and portable rocking chair
View Patent ↗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.

8. The collapsible and portable rocking chair according to claim 1 , wherein the seat support members of the side frame assemblies are interconnected by at least one transversely extending seat connector member and the back support members of the side frame assemblies are interconnected by at least one transversely extending back connector member.
9. The collapsible and portable rocking chair according to claim 1 wherein the seat panel and the backrest panel are made of a flexible material.
10. A collapsible and portable rocking chair comprising:
a pair of side frame assemblies including a front leg member, a rear leg member, a back support member, and a fulcrum member defining a fulcrum point at a terminal end thereof adapted for contacting the ground surface upon which the chair sits in a set-up condition thereof and about which the chair can move between forward and rearward rocking positions, said members comprising each side frame assembly being pivotally interconnected for folding movement between the set-up condition of the chair and a collapsed condition of the chair;
at least one rocker mechanism attached to each side frame assembly for supporting the chair during movement between said forward and rearward positions; and
a flexible seat and a flexible backrest secured to and extending between the side frame assemblies.
11. The collapsible and portable rocking chair according to claim 10 , wherein said rocker mechanism is attached to at least one of the front leg member and the rear leg member of each side frame assembly.
12. The collapsible and portable rocking chair according to claim 11 , 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.
13. The collapsible and portable rocking chair according to claim 12 , wherein a sleeve is associated with the lower-most end of each of the front leg member and the rear leg member of each side frame assembly, each said sleeve housing a spring to which a respective member is connected.
14. The collapsible and portable rocking chair according to claim 10 , wherein said fulcrum member extends from an intermediate point on the rear leg member.
15. The collapsible and portable rocking chair according to claim 10 , wherein each side frame assembly further comprises a seat support member pivotally interconnected with other members of said side frame assembly defining a seat support for supporting the flexible seat.
16. The collapsible and portable rocking chair according to claim 10 , wherein each side frame assembly further comprises an armrest.
17. The collapsible and portable rocking chair according to claim 16 , further comprising a common pivotal connection between the upper extremity of said front leg member, the upper extremity of said rear leg member and a forward portion of the armrest, and a pivotal connection between the rearward extremity of the armrest and an intermediate portion of the back support member such that the armrest is generally horizontally disposed when the chair frame is in the set-up condition.
18. The collapsible and portable rocking chair according to claim 10 , wherein the side frame assemblies are interconnected by at least one transversely extending connector mechanism.
19. The collapsible and portable rocking chair according to claim 18 , wherein the connector mechanism comprises a pair of connector members pivotally connected to each other at a respective intermediate portion thereof about a pivot axis and pivotally connected at terminal extremities thereof to each of the side frame assemblies.
