Abstract
The present invention provides stability for a decorative tree. Specifically, the decorative tree will have a base part, the lower section of which fits into a stand assembly and an upper section of which includes receiving means for an internal sleeve. The internal sleeve is sized to snugly receive a tree trunk and is formed to provide a plurality of clearances between the internal sleeve and the base part to accommodate parts associated with the trunk of the decorative tree such as bundles of fiber optics. By separating the parts to be associated with said trunk from the trunk, the stability of the entire decorative tree is vastly improved
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates in general to an apparatus for stabilizing artificial Christmas or decorative trees. More specifically, the present invention provides stability at the base of an artificial tree by providing a tighter fit within a sleeve of the base.




2. Description of the Prior Art




It is known in the art to provide artificial trees for decoration. Such trees are equipped with a base and stand such that the tree is free-standing. Some stands include feet, and some are simply circular. Most of the prior art devices include a base piece wherein one end fits around the trunk of the artificial tree and the other end fits into the stand. Many of these base pieces are simply hollow cylinders and some are integrally associated with the stand.




In the prior art, the circumference of the base piece or hollow cylinder had to be of such a size that not only the trunk of the artificial tree could be inserted, but also any parts that needed to be associated with or aligned with the trunk. For example, bark if the trunk is wood or some other substance if the trunk is not; optical fibers if they are to be distributed in various parts of the tree; electric or light cords; or brackets for low branches. As the circumference of the base piece was increased to accommodate these other parts, the stability of the tree was severely impaired by the give and softness such pieces introduced between the trunk and the inside surface of the base piece.




The present invention differs from the above referenced inventions and others similar in that these prior devices do not provide a way to allow for the parts that need to be associated with the trunk of the tree without sacrificing the tree's stability. Therefore, it is one objective of the present invention to accommodate associated parts separately from the trunk. It is a second objective of the present invention to increase the stability of a decorative tree.




SUMMARY OF THE INVENTION




The present invention provides stability for a decorative tree having a base part, the lower section of which fits into a stand assembly. An upper section of the base part includes receiving means for an internal sleeve which is sized to receive a tree trunk and is formed to provide a plurality of clearances to accommodate parts associated with the trunk of the decorative tree. Generally, said means to receive the trunk is a hollow cylinder with inner and outer surfaces and of a size into which said trunk fits snugly. Said plurality of clearances are bounded by a plurality of protrusions on the outer surface of the internal sleeve and the inner surface of the base part. By separating the parts to be associated with said trunk from the trunk by using said plurality of protrusions and clearances, and by providing means to receive and snugly fit the trunk, the stability of the entire decorative tree is vastly improved




Other objects, features, and advantages of the present invention will be readily appreciated from the following description. The description makes reference to the accompanying drawings, which are provided for illustration of the preferred embodiment. However, such embodiment does not represent the full scope of the invention. The subject matter which the inventor does regard as his invention is particularly pointed out and distinctly claimed in the claims at the conclusion of this specification.

DESCRIPTION OF THE PREFERRED EMBODIMENT(S)




Referring to

FIG. 1

, a preferred embodiment of the present invention is shown and includes a decorative tree


10


which includes a stand assembly


12


, a base part


14


, a trunk


16


and tree branches


18


.




As best shown by the cross-section in

FIG. 2

, an internal sleeve


20


functions as a means to receive said trunk


16


and comprises bottom and top ends


22


and


24


respectively (see also FIG.


3


), a cylindrical shaped body


26


with an inner surface


28


, an outer surface


30


, a plurality of protrusions


32


which are spaced apart along said outer surface


30


of said internal sleeve


20


and run longitudinally thereof between said bottom and top ends


22


,


24


. Best shown in

FIG. 4

, a lip


34


runs around the internal surface


28


at the bottom end


22


. In the preferred embodiment, the internal surface


28


of said internal sleeve


20


is provided with numerous spaced apart, longitudinally aligned friction strips


36


that are tapered in height running from bottom to top to increase the amount of friction they present to the trunk


16


as it is inserted into the sleeve


20


to create a tight, fit therebetween.




Said base part


14


(shown in

FIG. 5

) comprises upper and lower sections


44


and


46


respectively, an inner surface


48


and means


50


to receive each of said protrusions


32


for securing said internal sleeve


20


in position within said base part


14


. When the sleeve


20


is assembled within the base part


14


, spaces


52


are formed between the outer surface


30


of the sleeve


20


and the inner surface


48


of the base part


14


. The internal sleeve


20


is stabilized by the association of said protrusions


32


and said means


50


to receive them located on the inner surface


48


of said base part


14


.




In the preferred embodiment, said means


50


to receive said protrusions


32


comprises channels


58


formed by closely spaced apart elongated ribs


60


into which the protrusions


32


slide. Each of the channels is equipped with a stop tab


62


at the lower edge of the channels to prevent said sleeve


20


from falling out of the channels


58


. See FIG.


4


.




In the preferred embodiment shown in

FIG. 6

, the invention provides stability for a Christmas tree illuminated by optical fibres


70


. First, the internal sleeve


20


is inserted into said base part


14


by sliding the protrusions


32


into said channels


58


to the stops


62


. Said internal sleeve


20


should be oriented such that said inside lip


34


is near the stop tabs


62


at the lower edge of the channels


58


of said base part


14


. It is against this lip


34


that said trunk


16


will rest.




Said fibres


70


each comprise a distal


72


and a proximal end


74


. All proximal ends


72


of said fibres


70


are located in bundles near a light source


76


in said stand assembly


12


. Each bundle of fibres


70


is then threaded through one of said spaces


52


created between said inner surface


48


of said base part


14


and the outer surface


30


of said internal sleeve


20


. The base part


14


is then secured to said stand assembly


12


such that said proximal ends


74


are near said light source


76


.




Next, said trunk


16


is inserted in the internal sleeve


20


where it is gripped tightly by said friction strips


36


and until it reaches the inside lip


34


which functions as a stop. Finally, above the internal sleeve


20


, said optical fibres


70


are associated with said trunk


16


and are directed to said tree branches


18


.




Thus, the present invention has been described in an illustrative manner. It is to be understood that the terminology that has been used is intended to be in the nature of words of description rather than of limitation.




Many modifications and variations of the present invention are possible in light of the above teachings. Therefore, within the scope of the appended claims, the present invention may be practiced otherwise than as specifically described.
