ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention is related to a novel structure for Christmas trees, and especially to the structure of an artificial Christmas tree which can be easily manufactured and conveniently used.
2. Description of the Prior Art
Christmas is a great festival for western people, and people in the entire world nowadays also celebrate this big festival. Beside those activities of celebration held by various organizations and companies, people deck the halls in families with Christmas trees to welcome Christmas day and add joyful air to it. Christmas trees can be divided into two kinds, one directs to the real trees decorated with various decorations and LED lamp sets; the other directs to the artificial decorated trees taking the places of real trees which are gradually more and more difficult to obtain year by year. And artificial decorated trees used as Christmas trees are gradually popularized.
Conventional artificial Christmas trees (please refer to
FIGS. 1 and 2
) each is comprised mainly of a base A, a trunk B and a lot of branches C. Wherein, the branches C each is made by assembling plastic leaves E on a stem D and is secured individually on the trunk B. When the branches C are assembled on the trunk B, they are inclined downwardly. Hence when users put LED lamp sets F and decorations G thereon, the LED lamp sets F can only be wrapped around smoothly by folding of the branches C, while the decorations G must be hung by bending the branches C. However, bending or folding of the branches C for fixing the LED lamp sets F and the decorations G endues the Christmas trees with the following disadvantages:
1. The branches C of the Christmas trees are mounted together with the plastic leaves E when the stems D are twisted for fixing the plastic leaves E. The plastic leaves E are elongated and flat, they shall be equidistantly fixed on each stems D to form bunches. After fixing, the plastic leaves E are trimmed; then the stems D are fixed on the trunk B. Manufacturing of such branches C not only is bothersome and time consuming, but also is resource wasting by the fact that the debris resulted from trimming after fixing of the plastic leaves E are not useful.
2. Fixing of the stems D on the trunk B by twisting of the stems D is subjected to dropping of lot of plastic leaves E and is bad for environment neatness. And the plastic leaves E are subjected to deformation by pressing or collision during packaging and shipping.
3. When the LED lamp sets F and the decorations G are hung on a Christmas tree and are adjusted for positioning, the stems D are supposed to be bent. However, amount of the LED lamp sets F and the decorations G and their locations of fixing are large, bending of a plurality of stems D will adversely influence the aesthetic appearance of the whole Christmas tree.
4. When in adjustment of the LED lamp sets F and the decorations G hung on a Christmas tree, they shall be in the first place taken down from the branches C. Thereafter, they are fixed on different branches C. Not only such a mode of adjustment is bothersome, but also the plastic leaves E are subjected to dropping when the branches C are repeatedly bent and repeatedly recover.
5. Such a Christmas tree is extremely time and man work consuming in assembling due to the bothersome procedure of manufacturing thereof. Therefore, price of them is high.
SUMMARY OF THE INVENTION
In view of the disadvantages resided in the conventional Christmas trees, the inventor of the present invention provides a novel structure for Christmas trees to get rid of the defects of the conventional Christmas trees after study, tests and continuous improvement based upon his professional and practical experience of years in designing and manufacturing the same kind of products.
Particularly, the structure of each of the Christmas trees of the present invention is like this, a lot of leaves thereon are formed by circling of metallic spring like coils and are used for direct hanging of the LED lamp sets which are prevented from dropping. The decorations on the Christmas tree can also be securely hung on the leaves. And an object of hanging the decorations in positions without bending the leaves can be achieved.
The primary object of the present invention is to provide a novel structure for Christmas trees made of metal. It can not only enhance the strength of the structure, but also prevent the Christmas trees from deformation during packaging and shipping. The leaves of the Christmas trees are made from spring like coils providing only slight elasticity; hence various sizes of leaves formed can be prevented from deformation as well as damage. And by providing the spring like coils, the decorations can be conveniently adjusted in hanging and can be surely hung at desired locations. This can solve the defects resided in hanging of the conventional Christmas trees. Such a Christmas tree not only is structurally simple and tough, but also can largely simplify the process of production and reduce the cost of production, and thus provides a practical as well as economic structure of Christmas tree.
The present invention will be apparent after reading the detailed description of the preferred embodiments thereof in reference to the accompanying drawings.
