发明名称 Play pool has upper ring has center ring and bottom surface formed from plastic circle, whereby center ring has upper side and lower side for connection to upper ring and bottom surface by thermal process
摘要 <p>The play pool has an upper ring (1) rolled to form a hollow component, and a center ring (3) and bottom surface (2) formed from a plastic circle (30), whereby the center ring has an upper side and a lower side for the connection to the upper ring and bottom surface by a thermal process. The upper side and lower side are adapted to different circumferences of the upper ring and bottom surface. Wedge-form slots extend in the vertical direction from the upper side to the lower side to form trapezoids, whereby the inclined side sections of adjacent trapezoids are interconnected by a thermal process to form the center ring.</p>
