发明名称 Multi-roller beach chair
摘要 A beach chair having multiple rollers is provided which is electrically insulated and that is quiet when rolled upon a hard surface. The frame of the beach chair is curved to fit the curves of the human body so that the weight is evenly distributed over the whole body surface. Thus, edema due to excessive pressure on small body surface areas is eliminated. The open, hollow construction of both the frame and the rollers allows water to enter and exit easily. In this way the chair remains stable and does not float away with wave action. The mulitple, independent rollers allow this lightweight beach chair to turn easily while gripping the sand so that it does not slide sideways. This beach chair rolls easily allowing it to be useful in transporting heavy items over long distances effortlessly over sand, gravel, or pavement without noise.
