Protective flooring unit with flap
A protective flooring unit having a flap along an outer edge of the unit to enable separate flooring units to be joined by placing an overlapping portion of a second flooring unit on top of the flap of a first unit. The overall thickness or height of the flap is less than the maximum thickness of the main body of the unit such that there is not a significant rise or bump in the overlapping region.
1. A protective flooring unit comprising:
a main body having opposed first and second edges and opposed third and fourth edges, said main body comprising an overlapping portion extending adjacent and parallel said second edge, wherein a maximum thickness of said overlapping portion and of said third and fourth edges approximately equals a maximum thickness of said main body; and
a single flap, wherein said flap is of uniform thickness and extends outwardly from said first edge of said main body, and wherein a thickness of said flap is less than a maximum thickness of said main body.
2. The protective flooring unit of claim 1 , wherein said flooring unit is comprised of a sheet of material which may be manufactured to have varying thickness at different regions of the sheet.
3. The protective flooring unit of claim 2 , wherein said flooring unit is comprised of a material selected from the group consisting of plastic, rubber, rubber composites, vinyl, foam and combinations thereof.
4. The protective flooring unit of claim 1 , wherein said flap is formed integral with said main body.
5. The protective flooring unit of claim 1 , wherein said main body has raised pads extending along an upper surface of the main body.
6. The protective flooring unit of claim 5 , wherein said raised pads comprise ribs running a length of the flooring unit in a direction parallel the flap.
7. A protective flooring unit comprising:
a main body having upwardly extending raised pads and opposed first and second edges and opposed third and fourth edges, said main body comprising an overlapping portion extending adjacent and parallel said second edge, wherein a maximum thickness of said overlapping portion and of said third and fourth edges approximately equals a maximum thickness of said main body; and
a single flap, wherein said flap is of uniform thickness and extends outwardly from said first edge of said main body, and wherein said flap has a thickness that is less than a maximum thickness of said main body.
8. The protective flooring unit of claim 7 , wherein said raised pads comprise ribs running a length of the unit in a direction parallel the flap.
9. The protective flooring unit of claim 7 , wherein said flap has a thickness that is equal to or less than a minimum thickness of said main body.
10. The protective flooring unit of claim 7 , wherein said overlapping portion has a maximum thickness that is less than a maximum thickness of a remainder of said main body.
11. The protective flooring unit of claim 10 , wherein said overlapping portion has a width about equal to a width of said flap.
12. The protective flooring unit of claim 7 , wherein a combined thickness of a maximum thickness of said overlapping portion and a thickness of said flap is no more than twice a maximum thickness of said main body.
13. The protective flooring unit of claim 7 , wherein a combined thickness of a maximum thickness of said overlapping portion and a thickness of said flap is about equal a maximum thickness of said main body.
