Abstract
Abstract The holder comprises a pot having a screw for fixing a tree stump in the pot chamber by clamping it against the opposite wall of the pot. The wall of the pot forms three inwardly and slightly upwardly extending cylindrical cavities at its base. Three legs are provided, one for each cavity. Each leg has a cylindrical spigot at its inner end and a main shank. The longitudinal axis of the spigot is offset slightly, relative to the axis of the shank. When the spigots are inserted into the cavities so that the legs are assembled with the pot and the assembly is nesting on a support surface, then manual rotation of a single leg will induce tilting of the pot. Thus there is provided a holder having a single screw clamping system and a rotatable leg levelling system.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
239 words
A tree holder comprising: first means for clamping and supporting the stump of a tree to hold the tree upright; said first means comprising a base having a periphery, said first means forming three cylindrical first surfaces that are downwardly angled from horizontal and located at generally equally spaced apart positions around the periphery of the first means base; and three legs for supporting the first means in an elevated position, each leg having inner and outer end portions, said outer portion having a length that is several times the length of the inner portion, which combine to form a unit so that the leg portions will turn together, said inner end portion forming a cylindrical second surface adapted to longitudinally engage one of the cylindrical first surfaces to interlock with the first means with a tolerance that is sufficiently close so that the leg will not counter-rotate when the first means is loaded with a tree but that is sufficiently loose so that the leg may still be manually rotated, the outer end portion and cylindrical second surface of each leg each having a longitudinal axis, said axes being generally linearly aligned but offset and intersecting each other at a small acute angle relative to each other; whereby, when the legs are interlocked with the first means and the resulting assembly is resting on a support surface, manual rotation of a leg induces tilting of the first means.
Claim 2
Dependent Claim
239 words
A tree holder comprising: first means for clamping and supporting the stump of a tree to hold the tree upright; said first means comprising a base having a periphery, said first means forming three cylindrical first surfaces that are downwardly angled from horizontal and located at generally equally spaced apart positions around the periphery of the first means base; and three legs for supporting the first means in an elevated position, each leg having inner and outer end portions, said outer portion having a length that is several times the length of the inner portion, which combine to form a unit so that the leg portions will turn together, said inner end portion forming a cylindrical second surface adapted to longitudinally engage one of the cylindrical first surfaces to interlock with the first means with a tolerance that is sufficiently close so that the leg will not counter-rotate when the first means is loaded with a tree but that is sufficiently loose so that the leg may still be manually rotated, the outer end portion and cylindrical second surface of each leg each having a longitudinal axis, said axes being generally linearly aligned but offset and intersecting each other at a small acute angle relative to each other; whereby, when the legs are interlocked with the first means and the resulting assembly is resting on a support surface, manual rotation of a leg induces tilting of the first means.
Claim 3
Dependent Claim
20 words
The tree holder as set forth in claim 1 wherein: the first means comprises a pot forming the first surfaces.
Claim 4
Dependent Claim
236 words
A tree holder comprising: a pot having means for clamping and supporting the stump of a tree to hold the tree upright; said pot comprising a base having a periphery, said pot forming three cylindrical first surfaces that are downwardly angled from horizontal and located at generally equally spaced apart positions around the periphery of the pot base; and three legs for supporting the pot in an elevated position, each leg having inner and outer end portions, said outer portion having a length that is several times the length of the inner portion, which combine to form a unit so that the leg portions will turn together, said inner end portion forming a cylindrical second surface adapted to longitudinally and frictionally engage one of the cylindrical first surfaces to interlock with the pot with a tolerance that is sufficiently close so that the leg will not counter-rotate when the pot is loaded with a tree but is sufficiently loose so that the leg may still be manually rotated or withdrawn, the outer end portion and cylindrical second surface of each leg each having a longitudinal axis, said axes being generally linearly aligned but offset and intersecting each other at a small acute angle relative to each other; whereby, when the legs are interlocked with the pot and the resulting assembly is resting on a support surface, manual rotation of a leg induces tilting of the pot.
Claim 5
Dependent Claim
236 words
A tree holder comprising: a pot having means for clamping and supporting the stump of a tree to hold the tree upright; said pot comprising a base having a periphery, said pot forming three cylindrical first surfaces that are downwardly angled from horizontal and located at generally equally spaced apart positions around the periphery of the pot base; and three legs for supporting the pot in an elevated position, each leg having inner and outer end portions, said outer portion having a length that is several times the length of the inner portion, which combine to form a unit so that the leg portions will turn together, said inner end portion forming a cylindrical second surface adapted to longitudinally and frictionally engage one of the cylindrical first surfaces to interlock with the pot with a tolerance that is sufficiently close so that the leg will not counter-rotate when the pot is loaded with a tree but is sufficiently loose so that the leg may still be manually rotated or withdrawn, the outer end portion and cylindrical second surface of each leg each having a longitudinal axis, said axes being generally linearly aligned but offset and intersecting each other at a small acute angle relative to each other; whereby, when the legs are interlocked with the pot and the resulting assembly is resting on a support surface, manual rotation of a leg induces tilting of the pot.
