Abstract

A composite table top including a top plate having an outer and an inner surface, a bottom plate comprising a plurality of projections, each of the plurality of projections having a top defining a top surface. The composite table top has at least a pair of reinforcement inserts disposed at two opposite edges of the bottom plate. The sum of the top surfaces of the plurality of projections is 30%-70% of the upper surface of the bottom plate.

Claims

1. A table top comprising:

an inner table top section and a perimeter section around a perimeter of the inner table top section, the perimeter section having four sides;

the inner table top section having an inner section of a top plate and an inner section of a bottom reinforcing plate (1004);

the top plate (1002) having a top surface and a bottom surface;

the inner section of the bottom reinforcing plate having a plurality of substantially uniformly distributed projections, with the bottom surface of the top plate attached to and supported by top surfaces of the projections;

the perimeter section of the table top including a downward flange around outer peripheral edges of the top plate;

the perimeter section of the table top including an upward flange on the bottom reinforcing plate around outer peripheral edges of the bottom reinforcing plate, with the upward flange (1018) including a first substantially vertical surface (1308) and with the downward flange and a second substantially vertical surface extending down from a downward sloped surface (1302), the second substantially vertical surface partially overlying, parallel to and in contact with the first substantially vertical surface, and with the second substantially vertical surface forming an outermost surface of the table top;

the upward flange and the downward flange in part forming an enclosed cavity around the four sides of the perimeter section;

the top surface of the top plate having a downward inclined portion having an inner end adjoining a flat inner area of the top surface of the top plate, and the inclined portion having an outer end adjoining an upper end of the second substantially vertical surface forming an outermost surface of the table top;

a hollow tubular reinforcement frame inside of the cavity and extending around the four sides of the perimeter section, the hollow tubular reinforcement frame having a first side alongside and parallel to the substantially vertical surface of the upward flange, the hollow tubular reinforcement frame having a second side alongside and parallel to the downward sloped surface (1302) of the downward flange, the second side at an obtuse angle to the first side, the hollow tubular reinforcement frame having a third side parallel to the first side and at an acute angle to the second side, and with the third side longer than the first side; and

first and second pairs of folding leg assemblies (702) at opposite ends of the table top, with each folding leg assembly pivotally attached to the hollow tubular reinforcement frame.

2. The table top of claim 1 wherein the projections are formed using a vacuum forming process.

3. The table top of claim 1 further including first and second hinges on adjacent corners of the hollow tubular reinforcement frame.

4. A table top comprising:

an inner table top section and a perimeter section extending entirely around the inner table top section;

the inner table top section having an inner section of a top plate and an inner section of a bottom reinforcing plate;

the top plate having a top surface and a bottom surface;

the inner section of the bottom reinforcing plate having a plurality of projections, with the bottom surface of the top plate attached to the projections; and

wherein a cross-section of the perimeter section is in the shape of a rhombus, with a shortest side of the rhombus forming an outer edge of the table top.
