Abstract
A spring chair (cushion) structure in which the spring chair (cushion) structure, elastic body, flexile rods have sufficient pliancy and, furthermore, are slanted at equal intervals apart such that they conjoin two frame members into a single structural entity. When sitting in the spring chair (cushion) structure, body weight is utilized to directly cause the torsional resiliency of the elastic body to produce an appropriate spring-loaded and buffered effect.
Claims5
A spring chair structure, comprising:
- an elastic body having two spaced-apart hoop-shaped frame members, and at least twelve flexile rods angularly-arranged and spaced from each other at equal intervals, with a first end of each flexile rod being attached to one of said frame members, and with a second end of each flexile rod being attached to another one of said frame members, each flexile rod being essentially straight over a maiority of its length, the elastic body being adapted to produce a balanced torsional resiliency;
- and
- a seat attached to said one of said frame members.
