Abstract
A rocking chair comprises a base portion and a seat portion and includes a pair of C-springs for coupling the base portion to the seat portion. The C-springs flex to provide the seat portion with a desirably smooth and soft rocking motion while providing excellent structural integrity. Each C-spring has a contoured cross-sectional profile that provides a spring stiffness adapted to provide a smooth and comfortable rocking motion for a wide variety of body weights. The contoured cross-sectional profile also provides a high torsional resistance for minimizing lateral rocking movement of the seat portion.
Claims19
A flexible coupling mechanism comprising a flat, elongate member having a first side and a second side and formed into a C-shaped spring, said elongate member including a channel extending longitudinally along said first side between a first end and a second end.
A flexible coupling mechanism comprising an elongate member having first and second ends, said elongate member being formed into a C-shaped member to provide an inner surface and an outer surface, wherein a channel extends longitudinally along said outer surface to provide a contoured cross-sectional profile.
A coupling mechanism adapted for providing a smooth deflection when subjected to a load comprising an elongate member having a substantially rectangular cross-section and first and second ends, said elongate member having an inner surface and an outer surface, wherein at least two parallel, spaced-apart channels extend longitudinally along said outer surface for providing a contoured cross-sectional profile.
A coupling mechanism adapted for providing a smooth deflection when subjected to a load, comprising:
- at least two elongate members each having a substantially rectangular cross-section and first and second ends, each of said elongate members having an inner surface and an outer surface and each being formed with a channel extending longitudinally along said outer surface;
- and
- a horizontal support coupled to said first ends of each of said elongate members.
A method of manufacturing a flexible coupling mechanism, comprising:
- providing an elongate member having a substantially rectangular cross-section and formed with a channel extending longitudinally along a top surface;
- bending said elongate member such that said channel is provided along an outer surface;
- and
- forming at least one hole through said elongate member for facilitating attachment of said elongate member to another component.
