Frame construction for jumping games. The frame construction consists of frame elements with projections and others with recesses to form a plug-in connection between them to produce a frame shape having the same surface on all sides and holding together through the tight fit between them. The frame elements fitted with projections are made as junction sections (2,6,10) and the frame elements with the recesses are formed as connecting stays (14). The junction sections are made as cross-, T-, or angle junction sections (10).
