The present invention relates generally to tree stands that accommodate relocation of trees and, more particularly, to a rolling tree stand with casters which allow for a stable rolling motion while the tree is upright, in combination with a pair of elevated side wheel casters which allow for tilting the tree and a stable rolling motion while the tree is tilted, and also including an inner support collar sleeve for providing additional support and preventing bending and damage to the tree's trunk from excess pressure caused when the tree is tilted to one side.
Artificial trees are widely used due to their durability, cost efficiency and consistent appearance. A well known occasion for use of artificial trees is the Christmas season wherein trees are customarily assembled, decorated and displayed in homes and businesses. Artificial trees are often constructed such that they can be shipped or stored in a disassembled state and assembled by the user at the desired location. At times it may be necessary to transport the tree from an installation location elsewhere, or in the case of a live-cut Christmas tree, for final removal of the tree. Prior art tree stands are stationary in nature and are not easily moved. In addition, the ceiling heights of many homes and offices today are 10 to 12 feet in height and higher while many doorways and other openings may be only 7 to 8 feet in height. The preferred height of a Christmas tree or other artificial tree is often the ceiling height. Consequently, there is a need for a tree stand which allows Christmas trees and other artificial trees to be tilted to one side and easily rolled through doorways and other openings which are shorter than the height of the assembled tree while remaining assembled and attached to their base to reduce or eliminate the time required for disassembly and reassembly.
It is an object of the present invention to provide an improved tree stand that accommodates relocation of a natural or artificial tree through a doorway or opening that is shorter than the tree. In accordance with this invention, an improved two-way rolling tree stand is provided which has a wide, stable base with integral, adjustable, and lockable rolling casters for rolling of a tree in an upright position as well as slightly elevated side wheel casters for tilting an attached tree and moving the tree in a tilted position through doorways and openings while maintaining stability and safety. Additionally, it is an object of the present invention to provide an improved tree stand that provides for an inner support collar that protects and supports the tree trunk from excess pressure caused by tipping the tree to the side when rolling the tree for relocation. The use of the present invention allows a tree to be moved in a quick, safe, easy and effective manner whether in an upright or tilted position. It will be understood that the present invention can be used to hold artificial trees or, alternatively, can be used with live-cut Christmas trees as well.
The foregoing and other objectives, features, and advantages of the invention will be more readily understood upon consideration of the following detailed description of the invention taken in conjunction with the accompanying drawings.

Some embodiments of the present invention, described with reference to
Some embodiments of the present invention comprise a planar base structure 10 to which is attached a series of casters 22 to maintain the tree in a vertical position for display or when moving in the vertical position. An angled support structure is attached to the planar base structure to provide support for the tree when tilted during movement through areas where the vertical movement of the tree would be awkward or prohibited. The angled support structure has attached to it a series of casters that contact the ground when the tree is tilted. These casters work in conjunction with some of the casters on the planar base structure to provide a stable moving platform for the tilted tree.
Some embodiments of the present invention may comprise a plurality of side wheel casters 22 supported by a plurality of side wheel caster supports 20 which allow for the rolling tree stand to be rolled in a tilted position, with some of the rolling casters 18 off (i.e. do not contact) the ground surface 30, while at least two of the rolling casters 18 and the side wheel casters 22 are in contact with the ground surface 30. In some embodiments the side wheel casters 22 may be mounted parallel to each other in a non-swivelling casterless manner. The side wheel caster supports 20 may be fixedly attached to the base 10 or may be attached in such a way as to allow for changes of the tilting angle. In some embodiments of the present invention the side wheel caster supports 20 may comprise a ratchet mechanism 26 which may allow the side wheel caster supports 20 to be adjusted to various tilt angles depending on the height of the tree being transported and the height of any openings the tree needs to pass through. Accordingly, the rolling, tiltable tree stand of the present invention has the versatility to be used for omnidirectional movement of a tree in an upright position and may be tilted and used for omnidirectional movement in a tilted position.
Some embodiments of the present invention, described with reference to
Some embodiments of the present invention may comprise a plurality of side wheel casters 22 supported by a plurality of side wheel caster supports 20. In some embodiments a series of two side wheel casters 22 may be provided attached to a side wheel caster support 20 integrally connected to circular base 10 which may extend out from and above the circular base 10 so as the two side wheel casters 22 are on a higher plane then the other plurality of rolling casters 18 so as to accommodate a tilting action. In some embodiments the side wheel caster supports 20 may be a single monolithic unit capable of supporting a plurality of side wheel casters. The side wheel caster supports 20 may be fixedly attached to the base 10 or may be attached in such a way as to allow for adjustments to the tilt angle theta 28. In some embodiments of the present invention the side wheel caster supports 20 may further comprise a ratchet mechanism 26 which may allow the side wheel caster supports 20 to be adjusted to various tilt angles depending on the height of the tree being transported and the height of any openings the tree may need to pass through. In some embodiments the ratchet mechanism may allow the tilt angle 28 to be adjusted in unlimited increments, single degree increments and in other embodiments the ratchet mechanism may allow the tilt angle 28 to be adjusted in 15 degree increments so that the tree may be tilted at an angle of 45 degrees, 60 degrees and 75 degrees from the level plane of the ground.
Some embodiments of the present invention, described with reference to
Some embodiments of the present invention may comprise a cylindrical trunk holder which is interchangeable with other cylindrical trunk holders of varying diameters so as to accommodate trees of varying trunk sizes. For example, in instances when the tree stand is to be used with live-cut Christmas trees a cylindrical trunk holder, designed for larger trunks, may be attached. In embodiments where a live-cut tree is to be used the cylindrical trunk holder may be designed to be water tight so that it may be filled with water. In some embodiments the cylindrical trunk holder may be sized with a diameter large enough to hold potted trees or large potted plants.
Embodiments of the present invention provide an improvement in tree stands and have the unique features of a circular base unit with casters which allow a stable rolling motion while a tree is rolled in an upright position in combination with side wheel casters which allow a stable tilting motion and a stable rolling motion while a tree is rolled in a tilted position and also including an inner support collar sleeve for providing additional support and preventing bending and damage to the tree's trunk during relocation.
