Collapsible foot structure enabling users having physical discomfort or mobility problems to easily and quickly complete the operations of folding and opening of the foot structure of an iv-drip stand
A collapsible foot structure for a supported object to slide on the ground as a base comprises a base body, plural supporting legs and plural rolling elements. The supporting legs are arranged around the base body and pivoted at one end of the base body. The rolling elements are arranged at the other end of the supporting legs, when the base body is forced to move downwards, the supporting legs are pivotally swung relative to the base body to open, and when the supporting legs are opened, they will be stopped by a stopper at the base body to accordingly terminate the pivotal swinging, and supported on the ground by the rolling elements the plurality of supporting legs are lowered by their own weights relative to the base body when the base body is lifted and moved upward, and the second ends of the plurality of supporting legs are gathered with each other and supported on the ground by the plurality of rolling elements, so as to be easily folded and opened, thereby constituting the present invention.一種可收折之腳座結構,供被支撐物以其作為底座而可滑行於地面,包括座體、支撐腳和滾動件,支撐腳設在座體周圍且以一端樞接在座體;滾動件設在支撐腳的另一端,在座體受力而下移時,支撐腳相對座體樞擺而張開,且支撐腳在張開時有阻擋部擋在座體而停止樞擺,並以所設之滾動件支撐在地面上;在座體被提起而上移時,複數支撐腳相對座體以自重而垂下,且複數支撐腳的第二端相互聚集並以所設之複數滾動件支撐在地面上,而可輕易地收折和張開,藉此構成本發明。1‧‧‧座體11‧‧‧插孔12‧‧‧容槽121‧‧‧頂緣122‧‧‧壁面2‧‧‧支撐腳21‧‧‧第一端211‧‧‧端面22‧‧‧第二端23‧‧‧軸件24‧‧‧尖部26‧‧‧斜面3‧‧‧滾動件31‧‧‧軸件32‧‧‧輪座33‧‧‧輪體4‧‧‧桿體
