Abstract

The present invention comprises a tree stand, especially suitable for Christmas trees, for holding and adjusting the longitudinal angle of a tree trunk placed in the stand. The stand comprises a base member, a cup member, and a means for selectively adjusting and locking the tree trunk in the stand in a fixed angular orientation. The tree stand of the present invention allows a tree trunk placed in the stand to be easily levelled so that the tree is aesthetically pleasing, appearing perpendicular to a floor surface. The present invention also includes a method of using a tree stand, with or without a cup member, which provides a means to easily and efficiently adjust the angular orientation of a tree trunk. The present invention further provides a means to monitor the level of water contained in the cup member.

Claims

1. A tree stand comprising:

a base member adapted to be supported on a floor and having an upwardly facing recess opening formed therein;

a cup member having a longitudinal axis received within the recess opening of the base member for movement to alter the angle of the longitudinal axis relative to the base member;

means to secure a tree within the cup member; and

means to selectively adjust and lock the cup member within the recess opening at different angular orientations of the longitudinal axis relative to the base member,

wherein the adjustment means comprises a fulcrum surface within the recess opening for engagement with the cup member to enable the cup member to be displaced by the fulcrum surface causing a change in the angular orientation of the cup member longitudinal axis relative to the base member.

2. A stand according to claim 1, wherein the adjustment and locking means comprises a projection extending from the cup member through at least a portion of the base member and a clamp member moveable along the projection for clamping engagement with said portion.

3. A stand according to claim 1, wherein:

the fulcrum surface comprises a plurality of projections formed between the cup member and the base member.

4. A stand according to claim 3, wherein:

the projections are flanges.

5. A stand according to claim 4, wherein:

the projections are an annular rib.

11. A tree stand according to claim 1, wherein:

the fulcrum surface comprises a curved projection on the cup member and a curved surface on the recess opening.

6. A tree stand for holding and levelling a tree trunk, comprising:

a base member adapted to be supported on a floor and having an upwardly facing recess opening formed therein;

a neck member having a bottom, an interior surface, and an exterior surface, the neck member extending through the recess opening;

a cup member rotatably coupled within the neck member, the cup member including a longitudinal axis and an exterior surface, the cup member further including a bottom;

at least one projection extending between the interior surface of the neck member and the exterior surface of the cup member such that the cup member is supported within the neck member for movement about a fulcrum provided by the projection; and

means to selectively lock the cup member within the neck member at different angular orientations of the longitudinal axis relative to the base member.

7. The tree stand of claim 6 wherein:

the projection extends from the cup bottom against the neck bottom such that the longitudinal axis of the cup member may be adjusted relative to the base member.

8. The tree stand of claim 6, wherein:

the projection is a plurality of flanges.

9. The tree stand of claim 6, wherein the means to selectively lock comprises:

a bolt member extending from the cup bottom through at least a portion of the neck bottom and a clamp member moveable along the bolt member for clamping engagement with said portion.

10. The tree stand of claim 6, further comprising:

means for monitoring a level of water contained in the cup member such that when the water level reaches a predetermined level, an indicator light is initialized.

12. A tree stand comprising:

a base member adapted to be supported on a floor and having an upwardly facing recess opening formed therein, the recess opening having at least a partially curved sidewall;

a cup member having a curved portion and a longitudinal axis, the cup member being at least partially received within the recess opening, the curved portion contacting the curved sidewall; and

means for adjusting the angular orientation of the longitudinal axis relative to the base member, said adjustment means including a fulcrum surface formed between the curved portion and the curved sidewall; and

means to secure a tree within the cup member.
