BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an artificial Christmas tree and, more particularly, to an artificial Christmas tree rendering increased ease and convenience in assembly and shipment of the artificial Christmas tree and quick shape restorability after the artificial Christmas tree is unpacked.
2. Description of the Related Art
In view of its simple assembly, complete and beautiful tree structure, and easy storage and relocation, undoubtedly, artificial Christmas tree is one of the most indispensable decorations during the Christmas holiday season. To give an artificial Christmas tree a natural and aesthetically appealing look, tree leaves are supposed to be correctly positioned and oriented as desired.
However, tree leaves of artificial Christmas trees available in the market must be manually adjusted by workers in the factory in terms of location and orientation of the tree leaves before shipment. Despite the availability of standard operation procedures for assembly of the artificial Christmas trees, under the circumstance that aesthetic judgment varies from person to person and product capacity is a major manufacturing concern, consistent and optimal shape of the artificial Christmas trees is hard to get. As warehousing and shipping costs are also critical to be taken into account, the artificial Christmas trees tend to be squeezed as much as possible especially when they are packed for shipping. After consumers receive and unpack the purchased artificial Christmas trees, tree leaves and branches of the artificial trees appear to be folded and distorted, giving a tree structure much less than expected by the consumers. Even though manufacturers of the artificial Christmas trees stress that the artificial Christmas trees may be made of steel wire, which is more rigid and less damage-prone, it is inevitable that the artificial Christmas trees eventually become distorted due to the weight and poor elasticity of the steel wires.
SUMMARY OF THE INVENTION
An objective of the present invention is to provide an artificial Christmas tree with multiple branch holders mounted along a longitudinal direction of the trunk and the leaves spread out after mounted on corresponding branches to achieve a Christmas tree structure with simple and easy assembly and three-dimensional spatial perception to viewers.

Each leafstalk seat 31E is structurally similar to the leafstalk seat 31 in FIGS. 12 and 12A. Each leaf holder 34E is mounted on a corresponding leafstalk seat 31E, and has two opposite walls 341E and a bridge portion 342E. The bridge portion 342E is formed between the two opposite walls 341E and has an urging portion 343E upwardly formed in a bottom portion of the bridge portion 342E. The inverted hook 43E of each leaf 40E is hooked around the urging portion 343E of the bridge portion 342E of a corresponding leaf holder 34E by way of hook-connection.
With reference to FIG. 1, when the artificial Christmas tree is assembled, the branch holders 21 are mounted along the longitudinal direction of the trunk 20 and are spaced apart from each other, and each branch 30 is mounted a corresponding mounting ear 211 of one of the branch holders 21, such that each leaf 40 can be extended and spread out according to the position of the corresponding mounting ear 211. As the mounting ears of each adjacent two of the branch holders 21 are alternately arranged, the leaves are directed to various directions for the artificial Christmas tree to exhibit three-dimensional spatial perception to viewers. Furthermore, since the included angle between each leafstalk seat 31 and a corresponding branch 30 on which the leafstalk seat 31 is formed ranges from 0 degree to 90 degrees, each leaf 40 can be arranged in a most appropriate manner in terms of location and orientation. Additionally, given the resilient metal wire 42 mounted inside each leaf 40, each leaf 40 possesses desirable elasticity and flexibility for the leaf 40 and a corresponding branch 30 to be closely attached to the corresponding branch 30 and to the trunk 20 when the leaf 40 and the corresponding branch 30 are subject to a compression force, such that the size of the artificial Christmas tree can be reduced to save warehousing and shipping costs. When the compression force is gone, the leaf 40 and the corresponding branch 30 can automatically bounce back to their original positions to exhibit an undistorted and original look without any effort for adjusting the branches 30 and the leaves 40.
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only. Changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
