Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to an artificial Christmas
tree, and more particularly to a rotatable and shape-changeable
Christmas tree.
[0003] 2. Description of the Prior Art
[0004] 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 INVENTION
[0005] The 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.
[0006] 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
[0007] FIG. 1 is an assembly view of a Christmas tree in accordance
with a preferred embodiment of the present invention;
[0008] FIG. 2 is an exploded view of a part of the Christmas tree
in accordance with the present invention, particularly showing how
the trunk and the bearing are assembled together;
[0009] FIG. 3 is an exploded view of the tree-crown decorative
assembly in accordance with the present invention;
[0010] FIG. 4 an illustrative view of showing that the tree-crown
decorative assembly is mounted on the top end of the trunk; and
[0011] FIG. 5 is an illustrative view of showing how the Christmas
tree in accordance with the present invention rotates.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0012] Referring to FIG. 1, a Christmas tree in accordance with a
preferred embodiment of the present invention is shown and
comprises a base 10, a trunk 20, a rotating device 30, a plurality
of bearings 40, a plurality of different sized annular support
devices 50, a tree-crown decorative assembly 60 and a plurality of
decorative leaves 70.
[0013] The base 10 is firmly placed on the ground.
[0014] The trunk 20 includes a plurality of straight pipes 21 and a
plurality of bent pipes 22, as shown in FIG. 2. Each end of the
respective bent pipes 22 is formed with an inserting portion 221 in
which being formed an aperture 222. The inserting portion 221 is
inserted in the end of the respective straight pipes 21, and in
each of the straight pipes 21 is formed an aperture 211 to be
aligned with the aperture 222 of the bent pipes 22. The straight
pipes 21 and the bent pipes 22 are assembled to one another by
screwing a locking member 23 into the aperture 211 of the straight
pipes 21 and the aperture 222 of the bent pipes 22. And one of the
straight pipes 21 is pivotally fixed to the base 10.
[0015] 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.
[0016] The bearings 40 are installed on the straight pipes 21 of
the trunk 20.
[0017] 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 FIG. 2, the inner ring 51 of
the annular support devices 50 is mounted on the bearings 40.
[0018] 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 FIGS. 3 and
4, the bracket 61 includes an upper ring 611, a lower ring 612,
four ribs 613 connected between the upper and lower rings 611 and
612, and a reinforcing rib 614 connected between two opposite ribs
613, thus forming a conical bracket 61. The positioning seat 62 is
formed with an axial hole 621 and defined with a locking groove 622
for mating with the reinforcing rib 614 of the conical bracket 61.
The connecting member 63 is inserted in the axial hole 621 of the
positioning seat 62. In the end of the connecting member 63 is
formed a groove 631 for mating with the reinforcing rib 614 of the
conical bracket 61, and in the positioning seat 63 is further
defined a connecting hole 632.
[0019] 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.
[0020] 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.
[0021] 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.
[0022] 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.
