  • Patent number: 5394808
    Abstract: A folding table has a unitary table top formed of molded plastic preferably having an outer shell of non-cellular plastic with a filling of light weight hardened foam. Pairs of spaced apart sockets are formed in the table top material at the underside of the table top and a cylindrical bushing is disposed in each socket. One of a pair of pivotable leg assemblies is coupled to each pair of sockets by a pair of pivot axle projections that extend into the sockets and bushings. At least one of the sockets of each pair has a depth at least equal to the combined distances that the pivot axle projections extend into the pair of sockets. This enables entry of the pair of pivot axle projections into the pair of sockets by inserting one of the projections deeply into the one socket and then partially withdrawing that projection while guiding the other projection into the other socket of the pair.

In the preferred form, the housing has an annular sidewall encircling a combustion chamber and an apertured inner sleeve having an upper edge that is of smaller diameter than the sidewall and which forms an open centered circular lip proportioned to receive and seat the rounded bottom of the wok. The housing attaches to a post and the post attaches to a base platform having an indentation shaped to receive and seat a pressurized fluid fuel tank. The tank is retained by a clamp arm extending from the post. The housing, post and base are preferably disengagable from each other to facilitate carrying and storage of the cooking apparatus.
