A leveling assembly (2) comprising at least two leveling elements (4, 6) and having an uppermost surface (10) for seating a free-standing object 18. Elements (4, 6) are generally wedge-shaped, have upper (10, 14) and lower (12, 16) surfaces angled to one another (38, 42), are adapted to be placed on

A leveling assembly (2) comprising at least two leveling elements (4, 6) and having an uppermost surface (10) for seating a free-standing object 18. Elements (4, 6) are generally wedge-shaped, have upper (10, 14) and lower (12, 16) surfaces angled to one another (38, 42), are adapted to be placed one on the other and rotated relative to one another in order to vary the angle between the uppermost and lowermost assembly (16) surfaces. The elements (4, 6) may have co-operating guiding means (78, 82) or co-operating connecting means (184, 187) to aid in rotating the elements (4, 6) relative to one another and to resist shifting. In addition, the surfaces (16, 56) of the elements (4, 52) may be adapted with concave or cavity portions (58) in order to allow better seating on a surface (8). Reference markings (22, 28) placed on the elements (4, 6) aid in determining a suitable rotation of the elements (4, 6) relative to one another in order to compensate for a given slope.

What is claimed is: 1. An adjustable leveling assembly for supporting and leveling a free-standing object comprising: a first leveling element having an upper surface and a lower surface; a second leveling element having a top surface and a bottom surface and a central cylindrical opening passing therethrough; cooperating guiding members on each of said first and second leveling elements; said upper surface lying substantially in a first plane and being adapted to support said free-standing object; said lower surface lying substantially in a second plane and being adapted to be in contact with said top surface; said top surface lying substantially in a third plane and being adapted to be in contact with said lower surface and to support said first leveling element, said first leveling element being adapted to be seated on said second leveling element and to be rotated in relation thereto; said bottom surface lying substantially in a fourth plane and being adapted to be placed in contact with a further surface; said first and second planes intersecting at a first intersection angle, and said third and fourth planes intersecting at a second intersection angle; whereby rotation of said first and second leveling elements in relation to one another varies the relative angle between said first plane and said fourth plane; and wherein said guiding members comprise a circular lip projecting and extending outwards from said top surface adjacent said central cylindrical opening and a circular channel recessed in said lower surface, wherein said circular lip is adapted to fit within said circular channel. 2. An adjustable leveling assembly for supporting and leveling a free-standing object comprising: a first leveling element having an upper surface and a lower surface; a second leveling element having a top surface and a bottom surface; cooperating guiding members on each of said first and second leveling elements; said upper surface lying substantially in a first plane and being adapted to support said free-standing object; said lower surface lying substantially in a second plane and being adapted to be in contact with said top surface; said top surface lying substantially in a third plane and being adapted to be in contact with said lower surface and to support said first leveling element, said first leveling element being adapted to be seated on said second leveling element and to be rotated in relation thereto; said bottom surface lying substantially in a fourth plane and being adapted to be placed in contact with a further surface; said first and second planes intersecting at a first intersection angle, and said third and fourth planes intersecting at a second intersection angle; whereby rotation of said first and second leveling elements in relation to one another varies the relative angle between said first plane and said fourth plane; and wherein: said guiding members comprise a substantially circular lip projecting from said lower surface and an outer perimeter of said top surface; said circular lip having radially inner and outer surfaces and having a lower edge, said lower edge being parallel to said upper surface and said lower surface being angled and recessed relative to said circular lip; said top surface being substantially circular; and said radially inner surface having a radius that is larger than a radius of said top surface. 3. The leveling assembly of claim 2 further comprising a perimeter wall depending from said upper surface. 4. An adjustable leveling assembly for leveling a free-standing object on a slope comprising: a top and a bottom element, said elements being generally wedge shaped in longitudinal section and being rotatable in relation to one another, said assembly having an uppermost surface lying in a first plane and a lowermost surface lying in a second plane, rotation of at least one of said elements relative to the other varying a relative intersection angle between said first plane and said second plane, said uppermost surface providing a seat for said free-standing object and said lowermost surface being in contact with said slope; co-operating guiding members on each of said top and bottom leveling elements; and wherein: said guiding members comprise a substantially circular lip projecting from said top element and an outer perimeter of said bottom element, said circular lip having radially inner and outer surfaces and a lower edge, said lower edge being parallel to said uppermost surface and a lower surface of said top element being angled in relation to said lower edge; said bottom element is substantially cylindrical having a radius; and said radially inner surface has a radius that is larger than said radius of said bottom element. 5. The leveling assembly of claim 4 further comprising a perimeter wall depending from said upper surface.
