BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a pre-lit metal frame Christmas tree, especially to a pre-lit metal frame Christmas tree that can be easily and efficiently assembled through metal stakes.

2. Description of the Prior Arts

To attract the consumers and promote their interest in purchasing the metal frame Christmas trees, the manufacturers, besides adding variations to the appearances of the conventional pre-lit metal frame Christmas trees, also endeavor to lower the retail price of the pre-lit metal frame Christmas tree. For economy in transportation, reduction of material and packaged size of the pre-lit metal frame christmas tree is one of the key factors to lower the retail price. Therefore, the manufacturers tend to dismantle the pre-lit metal frame christmas trees when displayed for sale and leave them to the consumers to assemble on their own.

However, to further reduce the volume of the packed conventional pre-lit metal frame christmas tree, usually the manufacturers will dismantle the ring shaped supporting frame of the Christmas tree into multiple arc shaped metal pieces. But the lighting strings of the Christmas tree are mounted securely on the ring shaped supporting frame beforehand, which means when the ring shaped supporting frame is dismantled into multiple arc shaped metal pieces, the lighting strings are bound to be bent, tangled or even damaged. The lighting strings which are tangled with the arc shaped metal pieces or other lighting strings make the assembly procedure more complicated and time consuming for the consumers.

To overcome the shortcomings, the present invention provides a pre-lit metal frame Christmas tree to mitigate or obviate the aforementioned problems.

SUMMARY OF THE INVENTION

The main objective of the present invention is to provide a pre-lit metal frame Christmas tree that is not only small in volume for storage but also easy to assemble. Specifically, to assemble the Christmas tree, users only need to mount the umbrella-shaped net light on the foot prod, unfold the umbrella-shaped net light, and then fix the Christmas tree by the metal stakes. The pre-lit metal frame Christmas tree has a foot prod, an umbrella-shaped net light, and multiple metal stakes. The umbrella-shaped net light is mounted on the foot prod and comprises an umbrella shaped frame and a light string unit. The umbrella shaped frame comprises a base, a trunk, multiple positioning rods, multiple fixing rings, and an upper fixing unit. The umbrella shaped frame is mounted on the foot prod, the trunk is mounted on the base and extends upwardly, the multiple positioning rods are transversely and pivotally connected to the base and arranged apart from each other, the fixing rings are each respectively mounted on an end of a respective one of the positioning rods, and the upper fixing unit is mounted on a top of the trunk. A top of the light string unit is annularly mounted on a top of the upper fixing unit, and a bottom of the light string unit is mounted on the multiple fixing rings. The multiple metal stakes are respectively mounted through the fixing rings and fix the positioning rods.

Given the forgoing structure of the pre-lit metal frame Christmas tree, during assembly of the Christmas tree, because most of the components are mounted together beforehand, the users only need to put the foot prod to the determined place, mount the umbrella-shaped net light on the foot prod, unfold the umbrella-shaped net light, and then mount the metal stakes through the corresponding fixing ring, after which the assembling procedure is completed. Thus, by omitting the components that require complicated assembling procedures, the structure of the present invention simplifies the assembling procedure.
