DEFINITION
Classification: 5/169
(under subclass 133) Devices provided with a fabric bottom supported at the ends and having, if any, a very loose connection with the side rails, so that the bottom hangs as a bag when the bed is folded.
(1) Note. Search should be made here particularly when there are specially-actuated tension devices to stretch the fabric as the bed is opened. If no modifications are introduced by thus suspending the bottom and it might equally well be connected laterally to the sections, search should be made in the type defined by the mode of arranging and folding the sections.
SEE OR SEARCH THIS CLASS, SUBCLASS:
15, for sofa beds having suspended bottoms.
149, through 158, for the folding structure of the rails.
165, for devices which tension a fabric bed bottom as the bed is opened.
