The present invention relates generally to the field of swivel supporting devices and more particularly to the field of Christmas tree stands.
It is known in the art to utilize a stand to secure a tree, such as a Christmas tree, in an upright position for display. The “tree” itself as used and described herein may be an entire tree or merely an upper portion of a tree or even a branch. For centuries, trees have been removed from their natural habitat and positioned for display, often indoors. Trees may be decorated with electric lights, candles, ribbon, tensile, stars, balls, fruits, nuts, candy, religious icons, angelic scenes, and various other ornamentations.
Most commonly, such trees for display have included evergreen conifers such as spruce, pine, and fir trees though other trees such as various hardwoods, palms, and various hollies have been utilized as well. Though traditionally live trees have been utilized, more recently, it has become common for artificial trees such as those made from polyvinyl chloride or another plastic, metal, composite, or other synthetic to be displayed.
It is desirable for such trees to be displayed in an upright erect position as they would appear in nature. As such, various forms of stands have been developed through the years in order to support and display the tree. Most commonly, the prior art teaches stands which attach to the base of the tree. These supports clamp, screw, or nail into a lower portion of the tree and rely on the rigidity of the tree's trunk or primary vertical branch to maintain the tree in an upright position. Because of varying diameters of tree trunks obtained, the prior art requires that the stands come in various sizes to accommodate different range trunk diameter. For instance, one stand might hold a trunk of 3-5 inches in diameter. Another stand might hold a trunk of 5-8 inches in diameter while another might hold a trunk of 8-10 inches in diameter. Unfortunately, most artificial trees have a much smaller diameter “trunk” which may be only 1-2 inches in diameter. As a result, many different types of stand are required depending on tree type and size. As such, there is a long felt need in the art for a tree stand which accommodates many types and sizes of trees.
The art of tree stands is bifurcated among stands for holding real trees and stands for holding artificial trees. In addition to the trunk size requirement described above, stands made for holding the narrow “trunk” of artificial trees do not include the water bucket portion typically associated with trees which hold real trees—the water bucket being utilized for supplying water to the tree to keep it from prematurely drying out. Thus, a tree stand for an artificial tree may not be effectively used to support a real tree. Thus, there is a need in the art for a tree stand which may effectively hold either real or artificial trees by accommodating a variety of trunk sizes and offering watering options.
As noted above, prior art supports require clamps, screws, or nails and the like which attach onto a lower portion of the tree. These devices may pierce the bark or skin of the tree at the base of the tree. Likewise, in the case of an artificial tree, the clamps create an attachment at the base of the tree only. In all of these instances, it is common for the tree to be subject to tipping or to lose its firm attachment to the support. The tree attached by one of these prior art means creates a pivot point about the attachment. That is, the tree is prone to tipping about this point so as to no longer be positioned in a vertical orientation, relative to horizontal ground, as is desirable. Likewise, a considerable force acts on this attachment point which may cause the attachment to weaken over time requiring additional adjustment. Because this is a large inconvenience as well as a potential hazard, there is a long felt need in the art for a tree support which is not prone to tipping and which does not require additional adjustment.
Likewise, because of the potential for tipping and the associated hazards, the supports of the prior art are also sized for tree height. The height of the tree can create a significant lever arm resulting in torque about the attachment point with taller trees applying more torque and potential for an accident. That is, the size and type of clamping to the base must also account for the height of the tree. Thus, there is a long felt need in the art for a support system which minimizes the detrimental torque about the attachment point of the support to the tree. There also a long felt need for a support which accommodates a variety of tree heights.
Further, the attachment methods of the prior art described above are ill suited for their intended purposes because, in many situations, the person installing the tree must craw under the tree to adjust the attachment mechanisms to ensure the tree is upright and vertical as desired. That is, because the attachment is located only at the base of the trunk of the tree, often upon initial installation and certainly upon performing the requisite adjustments, the person must lay prone on the floor and reach under the tree to adjust. Because this is a large inconvenience as well as a potential hazard, there is a long felt need in the art for a tree support which does not require adjustments to the vertical orientation of the tree only at the base of the support.
Because the art of decorative trees is, by definition, concerned with ornamentation, it is desirable that those who install trees and decorate trees be able to effectively and efficiently decorate and present the trees. Thus, it is common, especially for real trees, for the decorator to turn the tree around to determine the “best” side or sides of the tree for display. That is, a tree may have missing branch defining a “hole” in the tree which may not be desirable for view. In such circumstances, it may be desirable for the side with the hole to face a wall and so it may be desirable for the decorator to rotate the tree and its accompanying tree stand. Or, in another instance, a decorator may desire to decorate all sides of a tree, but one side of the tree may be inaccessible—such as a side facing a window. In such circumstances it is likewise desirable to rotate the tree and the tree stand. However, the prior art tree stands require the entire tree and the entire tree stand be rotated. Likewise, one wishing to rotate a prior art tree stand must lift the tree and the stand and rotate. Thus, there is a long felt need in the art for a tree stand which eliminates the requirement to rotate the tree and the stand and which facilitates movement of the tree from place to place.
It therefore is an object of the present invention to provide tree stand which accommodates both real and artificial trees of varying types, heights, and trunk sizes. It is an object of the present invention to provide a tree stand which may effectively hold either real or artificial trees by accommodating a variety of trunk sizes and offering watering options. It is a further object of the present invention to provide a tree stand which is not prone to tipping and which does not require additional adjustment. It is a further object of the present invention to provide a tree stand which does not require adjustments to the vertical orientation of the tree only at the base of the support. It is a further object of the present invention to provide a tree stand which facilitates movement of the tree from place to place.
These and other objects and advantages of the invention are achieved by providing a swivel tree stand device having a vertical pole attached by a swivel mechanism to a base set on casters. The pole is designed to attach at multiple points to the tree trunk and to extend perpendicular to the level ground and roughly parallel to the tree trunk. A water bucket which may be removable may be carried by the base for watering a live tree attached to the pole. The pole and an attached tree trunk may swivel about the base.
According to an embodiment of the invention, the base may comprise legs extending from the swivel. The casters may be attached to the legs. The base may comprise at least three such legs, with one caster attached to each leg.
According to an embodiment of the invention, the pole may be telescoping such that its height above the base may be extended or retracted depending on the height of the particular tree to be carried by the swivel tree stand device.
According to another embodiment of the invention, the pole may be of a fixed height.
According to another embodiment of the invention, at least one caster may be lockable via a braking device attached to the caster.
According to another embodiment of the invention, the swivel may lockable via a braking device attached to the swivel.
According to another embodiment of the invention, an electric motor may be attached to the swivel to enable the tree to rotate about the base via the swivel.
According to another embodiment of the invention, the attachment points of the pole to the tree may be hook and loop fasteners such as Velcro® brand fasteners.
According to another embodiment of the invention, the pole may be hollow to permit the concealment of an electrical connection. The pole may likewise comprise an electrical connection and one or more outlets for attaching electrical devices such as lights.
