DEFINITION

Classification: 267/103

(under subclass 80) Device in which the load receiving surface extends generally parallel to the frame and is connected thereto and maintained in a plane separate from the frame by springs.

(1) Note. The spacing spring means may be integral with and form an extension from the load receiving surface; however, to fall within the confines of this and the indented subclasses, there must be an identifiable portion which yieldingly supports the load receiving surface.
