Collapsible wheeled dual-chair

Abstract

A collapsible dual-chair with trolley has a frame configuration which includes a plurality of tubular legs pivotally connected by pins and joined together by pivotal joint members. The frame configuration is collapsible and forms a dual-seat support when fully opened. A rigid base having wheels is mounted to a joint member and is attached to the frame configuration at a low end thereof such that the frame configuration can be converted into a trolley mode to transport especially when collapsed.
