ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a water ball, and particularly to a replaceable and easily assembled water-ball decoration.
2. Description of the Prior Art
In conventional water-ball ornaments, the inner side of the neck part of the glass ball is closed and sealed with a leak-proof rubber plug, of which the inner center is glued with an ornament; the glass ball is filled with water before being mounted on a base part. The ornament in the glass ball is enlarged by means of the convex lens effect of the glass ball.
According to the aforesaid conventional ornament, the neck part of the glass ball and the base part are connected together by following the steps of mounting the neck part of the glass ball on the upper part of a cylindrical hole of the base part, and then filling a sealing plastic into the cylindrical hole by means of a plastic-filling gun so as to have the cylindrical hole and the neck part of the glass ball fastened together in the gap between them. The glass ball and the base part are connected together as one piece without being separated from each other again; in other words, the glass balls on two different ornamental base parts can not be exchanged.
SUMMARY OF THE INVENTION
The prime object of the present invention is to provide a water-ball decoration, in which the base part of the major ornamental part is furnished with at least a through cylindrical hole; the upper ring surface of the cylindrical hole is used for supporting and positioning the fastening base of the water-ball ornament; the lower ring surface of the cylindrical hole is used for receiving a fastening disk to be fastened in place with a screw, which is engaged with a nut under the bottom of the fastening base so as to facilitate the placement of different water-ball ornaments on the base part.
Another object of the present invention is to provide a water-ball decoration, in which the base part of the major ornamental part has a cylindrical hole with an upper ring surface to facilitate the positioning ring of the fastening base of the water-ball ornament so as to enable the water-ball ornament and the cylindrical hole of the major ornamental part to be properly positioned and connected together.
Still another object of the present invention is to provide a water-ball decoration, in which the fastening base is connected to the outer edge of the neck part of the glass ball in the water-ball ornament, and the fastening base covers the neck part of the glass ball and the leak-proof rubber plug so as to provide protection for the bottom of the water-ball ornament.
A further object of the present invention is to provide a water-ball decoration, in which the inside of the fastening base under the bottom of the water-ball ornament has a ring-shaped groove which includes an inner ring surface and an outer ring surface. There are quite short distance among the inner and outer ring surfaces and the bottom of the neck part of the glass ball and the inner surface of the leak-proof rubber plug. After a suitable amount of a sealing plastic is injected into the ring-shaped groove, the neck part of the glass ball should be moved to plug into the ring-shaped groove of the fastening base so as to enable the neck part of the glass ball and the fastening base to connect together as one piece.
Still a further object of the present invention is to provide a water-ball decoration, in which the diameter of the glass ball of the water-ball ornament may be different; the neck part of the glass ball is used for fitting the leak-proof rubber plug to seal in place, and the height thereof would not change much. The water-ball ornament can directly be placed on a table by means of a fastening base having a short outer cylinder.
Yet another object of the present invention is to provide a water-ball decoration, in which the center of the fastening base of the water-ball ornament has a nut for receiving a screw passing through a round hole of a fastening disk so as to have the water-ball ornament fixed on the base part of the major ornamental part.
