Abstract

A chair for use in construction including a receiving area and a plurality of legs extending downwardly from the receiving area. Each of the plurality of legs has a foot extending horizontally outwardly therefrom. The foot of one of the legs is separate from the foot of an adjacent leg. The receiving area and the plurality of legs are integrally formed together of a polymeric material. The receiving area has a generally parabolic indentation. A first pair of the plurality of legs extends in a plane transverse to a second pair of the legs. Each of the feet has a planar bottom surface with a projection extending downwardly therefrom. A projection is integrally formed with the feet.

Claims

1. A chair comprising:

a receiving area; and

a plurality of separate legs extending downwardly from said receiving area, each of said legs having a foot extending horizontally outwardly therefrom, a foot of one of said plurality of legs being separate from a foot of an adjacent leg, said receiving area and said plurality of legs being integrally formed together of a polymeric material, said foot having a generally planar bottom surface, said planar bottom surface having a projection extending downwardly therefrom, said projection having a point opposite said planar bottom of sufficient sharpness so as to engage a support surface upon which the chair is placed under load.

2. The chair of claim 1, said receiving area having a generally parabolic indentation formed therein.

3. The chair of claim 1, a first pair of said plurality of legs extending downwardly from an upper end of said receiving area and a second pair of said plurality of legs extending downwardly from a lower portion of said receiving area.

4. The chair of claim 3, said first plurality of legs extending in a plane transverse to said second plurality of legs.

5. The chair of claim 1, said legs being separate from each other below said receiving area.

6. The chair of claim 1, each of said plurality of legs having the foot extending outwardly therefrom in a generally L-shaped configuration.

7. The chair of claim 1, said projection having an inverted pyramidal configuration.

8. The chair of claim 1, said planar bottom surface having a first projection adjacent an inner edge and a second projection adjacent an outer edge of said planar bottom surface.

9. The chair of claim 1, said projection being integrally formed with said foot.

10. The chair of claim 1, said polymeric material being a glass-filled nylon material.
