  • Patent number: 4424912
    Abstract: A collapsable basket is disclosed, in which legs can be erected to a position in which the basket is supported above a floor, and in which the legs can be collapsed to allow the basket to rest on a floor without being supported by the legs. This erection and collapse of the legs is accomplished by handles located adjacent to the regions where the basket is grasped by a user, so that it is not necessary to let go of the basket to operate the legs. The invention is provided with various devices which prevent the legs from collapsing, once erected, unless such collapse is desired. Additionally, a special bearing is disclosed which is designed for use in this invention.
