Abstract

Abstract A ground support system for providing a stabilizing surface in conjunction with loose soil is disclosed. The system finds particular utility in agricultural applications, such as where horses, cows or bulls and the like are kept. The support system comprises a number of interlockable planar sheets, each planar sheet including a number of conical projections disposed on its bottom side. The conical projections are hollow and open-ended and, in combination with apertures defined in the planar sheet, permit fluids to pass through the system. Traction on the upper surface of each sheet is optionally provided by either scoring or by adhered reground material such as a plastic. The planar sheets may be anchored to the ground by a stake having at one end a conical plug attached thereto, the plug being matable with the inside of one of the conical projections.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 131 words
A ground support system for stabilizing a surface of loose soil, said system comprising: a substantially planar member, said planar member having a top side and a bottom side; said planar member including a plurality of spaced apart projections depending therefrom; and said planar member having a plurality of fluid-passing openings permitting the passage of water and waste liquid through said planar member; means for anchoring said planar member to a layer of soil beneath said planar member; and said anchoring means comprising an anchor stem having an upper end and a lower end; and a locking plug secured to and slidable along said anchor stem, said locking plug being cooperatively fittable within said inside of one of said projections, said locking plug having a top end and a bottom end.
Claim 2
Dependent Claim 131 words
A ground support system for stabilizing a surface of loose soil, said system comprising: a substantially planar member, said planar member having a top side and a bottom side; said planar member including a plurality of spaced apart projections depending therefrom; and said planar member having a plurality of fluid-passing openings permitting the passage of water and waste liquid through said planar member; means for anchoring said planar member to a layer of soil beneath said planar member; and said anchoring means comprising an anchor stem having an upper end and a lower end; and a locking plug secured to and slidable along said anchor stem, said locking plug being cooperatively fittable within said inside of one of said projections, said locking plug having a top end and a bottom end.
Claim 3
Dependent Claim 24 words
The system of claim 1 wherein said locking plug includes tapered sides defining a cone, said top end being wider than said bottom end.
Claim 4
Dependent Claim 43 words
The system of claim 1 wherein a locking ring is secured to and slidable along said anchor stem and is fitted next to said bottom end of said locking plug, said locking ring being wider than said bottom end of said locking plug.
