ABSTRACT:
A table tennis table has a lower frame and two playing surface boards. The lower frame comprises vertical struts which are used as carrier elements and are arranged opposite each other along the width of the table tennis table. The playing surface can be transferred from a first position, in which the playing surface boards are vertically oriented and the guides are arranged in a lower position, to a second position, in which the playing surface boards are horizontally oriented and the guiding elements are arranged in an upper position. Upper and lower safety levers maintain the guides in either position. An actuation lever moves the safety levers to allow movement of the playing surface.
