Rotatable and shape-changeable christmas tree
A rotatable and shape-changeable Christmas tree, wherein the trunk of the tree is pivotally installed on a base, and the trunk includes a plurality of straight pipes and a plurality of bent pipes being assembled to one another, on each of the straight pipes is arranged a bearing on which being mounted an annular support device, and between neighboring annular support devices are arranged a plurality of decorative leaves. During rotation of the trunk relative to the base, the annular support devices will be driven to rotate, and the decorative leaves will rotate along with the annular support devices and will appear to change in shape during the rotation of the annular support devices.
1. Field of the Invention
The present invention relates to an artificial Christmas tree, and more particularly to a rotatable and shape-changeable Christmas tree.
2. Description of the Prior Art
During the holiday seasons, homes are commonly adorned in and out with festive decorations. One common decoration is the artificial Christmas tree. Therefore, a large variety of Christmas trees have been made so far, some of them are decorated with different ornaments, such as light and acoustic devices, and some of them are foldable. However, very few of the conventional Christmas trees are changeable in shape.
SUMMARY OF THE INVENTIONThe primary objective of the present invention is to provide a rotatable and shape-changeable Christmas tree, wherein the trunk of the tree is pivotally installed on a base, and the trunk includes a plurality of straight pipes and a plurality of bent pipes being assembled to one another, on each of the straight pipes is arranged a bearing on which being mounted an annular support device, and between neighboring annular support devices are arranged a plurality of decorative leaves. During rotation of the trunk relative to the base, the annular support devices will be driven to rotate, and the decorative leaves will rotate along with the annular support devices and will appear to change in shape during the rotation of the annular support devices.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiments in accordance with the present invention.
BRIEF DESCRIPTION OF THE DRAWINGS
Referring to
The base 10 is firmly placed on the ground.
The trunk 20 includes a plurality of straight pipes 21 and a plurality of bent pipes 22, as shown in
The rotating device 30 is disposed in the base 10 and is fixed to the straight pipe 21 of the trunk 20 fixed to the base 10.
The bearings 40 are installed on the straight pipes 21 of the trunk 20.
The annular support devices 50 each includes an inner ring 51, an outer ring 52, and four ribs 53 connected between the inner and outer rings 51, 52, as shown in
The tree-crown decorative assembly 60 is installed on the top end of the trunk 20 and includes a bracket 61, a positioning seat 62 and a connecting member 63. With reference to
The decorative leaves 70 are attached between the outer rings 52 of the neighboring annular support devices 50, and between the connecting hole 632 of the connecting member 63 and the annular support device 50 at the end of the trunk 20.
When the rotating device 30 is turned on, it will rotate the straight pipe 21 disposed on the base 10. Due to the straight pipes 21 and the bent pipes 22 are assembled together by screwing the locking member 23 into the aperture 211 of the straight pipes 21 and the aperture 222 of the bent pipes 22, the straight pipes 22 will also be driven by the rotating device 30 to rotate along with the straight pipes 21.
When the trunk 20 is rotated by the rotating device 30, the annular support devices 50 will also rotate along with the trunk 20 since they are assembled together via bearings 40. Due to the annular support devices 50 are different in size, and due to the irregular shape of the trunk 20 formed by the straight pipes 21 and the bent pipes 22, the decorative leaves 70 between the annular support devices 50 will appear to change in shape during the rotation of the annular support devices 50.
While we have shown and described various embodiments in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
