Lightweight table with unitized table top

A lightweight, portable table of the type including a table top member and a pair of leg assemblies secured to a bottom side of the table top member, said leg assemblies including legs movable between a storage position in which the legs are retracted under the table and a use position in which the legs are extended downwardly from the table to support the table on a surface, the improvement wherein the table top member comprises:

• a table top element having a substantially planar top surface and a top periphery;
• a table bottom element having a bottom surface, a bottom periphery, a continuous rail-receiving apron depending from the bottom surface spaced inward from the bottom periphery along the entire periphery, said apron having first and second generally opposed side walls, a bottom wall therebetween and an open upper end, said top and bottom elements configured for mating engagement to form a core-receiving cavity therebetween, said cavity being in communication with the apron open end;
• a support rail in and extending along the entire apron;
• a hardened foam body joined to the table top and bottom elements, said foam body being formed around substantially all of the rail and being of sufficient volume to at least partially fill the apron to hold the rail in place therein, said foam body being provided with an inner edge defining a core-receiving space within the cavity;
• and
• a core element sized to extend across the core-receiving space between the top and bottom elements and having an outer edge adjacent to and joined with the foam body inner edge, said core element being made of a lightweight material and including a plurality of vertical walls in a substantially regular geometric pattern defining cells having void volumes.

In a lightweight, portable table including a unitized table top member and legs secured thereto, the improvement wherein the table top member comprises:

• a substantially planar table top element;
• a table bottom element, the table top and bottom elements forming a cavity therebetween and a table top member periphery,
• an apron depending from the table bottom element and extending adjacent the periphery, said apron forming a portion of the cavity;
• a rigid support member in the cavity and apron;
• a hardened foam body which (1) Ms an inner edge, (2) is joined to the table top and bottom elements, and (3) is positioned at least partially around the support member and is of sufficient volume to at least partially fill the apron to hold the support member in place therein;
• and
• a core element joined to the table top member within the cavity in a core-receiving space defined by the table top and bottom elements and the inner edge.

In a lightweight, portable table including a unitized table top member and legs secured thereto, the improvement wherein the table top member comprises:

• a substantially planar table top element;
• a table bottom element, the top and bottom elements forming a cavity therebetween and a table top member periphery;
• a support member in the cavity and extending along the periphery;
• a hardened foam body at least partially surrounding the support member, said foam body connecting the table top and bottom elements and the support member;
• and
• a core element joined to the table top member and foam body within the cavity in a core-receiving space defined by the table top and bottom elements and the foam body.

• a table bottom element, the top and bottom elements forming a cavity therebetween and a table top member periphery;
• a support member in the cavity and extending along the periphery;
• a hardened foam body at least partially surrounding the support member, said foam body being joined directly to the table top and bottom elements and securing the support member within the cavity;
• and
• a core element joined to the table top member and foam body within the cavity in a core-receiving space defined by the table top and bottom elements and the foam body.
