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;

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 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 including a first vertical surface and with the downward flange including a second substantially vertical surface extending down from a downward sloped surface, the second vertical surface partially overlying, parallel to and in contact with the first vertical surface, and with the second 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 vertical surface forming an outermost surface of the table top;

a hollow tubular reinforcement frame inside of the cavity, the hollow tubular reinforcement frame having a first side alongside and parallel to the vertical surface of the upward flange, the hollow tubular reinforcement frame having a second side alongside and parallel to the downward sloped surface 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 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 vacuum-formed.

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:

a top plate (1002) having a flat top surface (1012), a downward sloped surface (1302) adjoining the flat top surface (1012) at a perimeter of the top plate, and a downward flange (1010) adjoining the downward sloped surface (1302);

a bottom plate (1004) having an inner section joined to an outer section, the inner section including a plurality of projections, with a bottom surface of the top plate attached to the projections, the outer section having an upward sloped surface (1308) and an upward flange (1018) joined to the upward sloped surface, the downward flange (1010) parallel to and overlying the upward flange (1018), the downward flange (1010) perpendicular to the flat top surface (1012);

the downward sloped surface (1302), the upward sloped surface (1306), and at least one of the downward flange (1010) and the upward flange (1018), forming a trapezoid-shaped cavity (1314);

a tubular reinforcement (1008) in the cavity (1314), the tubular reinforcement having a trapezoid-shape cross section including first and second non-parallel sides, the downward flange overlying the first side and the upward flange overlying the second side.
