Abstract

A portable tray comprising a tray body and legs extending outward therefrom, the tray body and legs each having a core of a resiliently compressive matrix and an outer layer of visco-elastic material. A second embodiment comprises a tray body formed of a first air-filled chamber. Second and third air-filled chambers are mounted to the first air-filled chamber and spaced apart from one another to straddle the user'"'"'s legs.

Claims

1. A portable tray apparatus for providing a flat surface upon the lap of an operator, said apparatus comprising:

a tray body having damping and shock absorbing means, wherein said damping and shock absorbing means includes a first air chamber; and

support means extending outward in a first direction from said tray body.

2. A tray apparatus as set forth in claim 1, wherein said support means includes a second and third air chambers, said second and third chambers mounted to said tray body and spaced sufficiently apart from each other to straddle the operators'"'"'s legs.

3. A portable apparatus for straddling the legs of the operator and supporting food and drink upon the operator'"'"'s lap comprising:

a generally planar tray body having a core and a surface layer, said surface layer of a material with a high frictional coefficient and said core including a resiliently compressible, gas impregnated cell matrix, a first end and a second end, said first end substantially opposite said second end;

at least a first leg extending outward in a first direction from said first end; and

at least a second leg extending outward generally in said first direction, said second leg spaced apart from said first leg a sufficient distance to straddle the legs of the operator.

4. A portable apparatus as set forth in claim 3, wherein said matrix includes a plurality of air pockets separated by interconnecting walls.

5. A portable apparatus for supporting food and drink upon the lap of the operator, said apparatus comprising:

a generally planar tray body having a resiliently compressible air-filled chamber, a first end and a second end, said first end substantially opposite said second end;

a second air-filled chamber mounted to and extending outward in a first direction from said first end;

a third air-filled chamber mounted to and extending outward in a said first direction, said third air-filled chamber spaced apart from said second air-filled chamber a sufficient distance to straddle the legs of the operator.

6. A portable apparatus as set forth in claim 5, wherein said first air-filled chamber includes a outer donut-shaped portion defining a passageway therethrough and a first and second connecting panels, said panels extending across said passageway to define a surface depression and a cavity therebetween.

7. A portable apparatus as set forth in claim 6, further including insulative means disposed within said cavity.
