Title: Table tennis table with outer metal plates - has chipboard centre with pyramid drill holes to absorb sun rays without distortion
Inventor: NEUMANN RUDOLF
IPC: A47B25/00
Filed: 1974-09-10
Abstract: The weatherproof table tennis table comprises a chipboard inner plate which has pyramid shape holes drilled in from the top and is enclosed top and bottom by all-weather metal plates. The top cover-plate is preferably of thin steel with angled edges to fit over the chipboard which is made of aluminium sheeting. The steel plate thus absorbs the solar heat and transfers it down through the pyramid holes and since the heat of the lower aluminium plate is not so great the latter must expand in order to remain straight and since aluminium expands more quickly than steel a perfectly aligned table top is always achieved.
