Abstract

A pier (10) for supporting an object, such as a mobile home coach frame, above the ground generally comprises support (80) supporting pipe (70) in a vertical position and against downward movement, platform (30) having a sloped upper surface (43) supported by top end (71) of pipe (70), and wedge (50) supported by platform (30); wedge (50) having slanted bottom (53) and horizontal top surface (60) for supporting the load. The height of pier (10) can be adjusted by sliding wedge (50) up sloped surface (43). Gripping ridges (45,55) on slope (43) and slanted bottom (53) interact so that the wedge (50) may not slide down the slope (43). Platform (30) includes a plurality of receptacles (40) for receiving top end (71) of pipe (70) for supporting sloped surface (43) at various heights.

a first receptacle disposed to receive the vertical support member at a first vertical distance from said slope; and

a second receptacle disposed to receive the vertical support member at a second vertical distance from said slope;

said second vertical distance differing from said first vertical distance.

7. A pier for supporting an object above the ground;

said pier comprising;

a vertical support member supported in a vertical position and against downward movement;

said vertical support member including;

a side wall

a top end; and

a bottom end;

a platform supported by said top end of said vertical support member;

said platform including;

a bottom including;

a plurality of receptacles;

each said receptacle for receiving said top end of said vertical support member for supporting said platform thereon;

each said receptacle including;

a wall bearing against said side wall of said vertical support member such that said platform cannot move horizontally relative to said top end of said vertical support member; and

a top connected to and supported by said bottom of said platform;

said top including;

a slope defining a slanted plane; and

gripping means for gripping a wedge; and

a wedge including;

a top defining a horizontal plane for supporting the object; and

a bottom connected to and supporting said top of said wedge;

said bottom of said wedge including;

a slant defining a plane parallel to and supported by said slope, said slant upwardly slidable on said slope such that the height of said top of said wedge is variable; and

gripping means for gripping interaction with said gripping means of said platform for preventing said slant from sliding down said slope.

8. The pier of claim 7 further including:

a support including;

a base for placement on the ground; and

a wall connected to said base and supporting said side wall of said vertical support member in a vertical position.

9. The pier of claim 7:

said base of said support supporting said bottom end of said vertical support member against downward movement.

10. The pier of claim 8:

said plurality of receptacles including;

a first receptacle disposed to receive said vertical support member at a first vertical distance from said slope; and

a second receptacle disposed to receive said vertical support member at a second vertical distance from said slope;

said second vertical distance differing from said first vertical distance.

11. The pier of claim 7:
