ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to touch controlled light emitted two balls instrument, and especially to ball instrument, wherein by a touch controlled electric switch, the terrestrial globe and heaven body ball will present various variations.
BACKGROUND OF THE INVENTION
A terrestrial globe is a tool for teaching, which is a miniature of a real globe. The maps of nations all over the world is depicted on the terrestrial globe so that people can know the geometry therefrom Another, a heaven body ball is also a teach tool and the map of a heaven body are depicted thereon. However, general terrestrial globes and heaven body balls are static without any variation and are manufactured separately. Thus, there is an eager demand for a varied terrestrial globe. Thereby, it can present many vivid variations so that the viewer will be interested.
SUMMARY OF THE INVENTION
Accordingly, the primary object of the present invention is to provide a touch controlled light emitted two balls instrument comprising the following elements. A seat with a two loops touch controlled sensing switch circuit system, one side of the seat is formed with a pivotal hole, and the opposite side of the seat is installed with a through hole used to mount with a first light source. A supporting frame is a cambered rod having an approximate C shape and is assembled on the pivotal hole of the seat. A screw rod is mounted on the top of the rod and an engaging rod is projected from the lower end thereof and may be pivotal connected with a second light source. A globe is a hollow and transparent round ball and a world map is depicted on the surface thereof. Holes are formed on the upper and lower ends thereof for being inserted by the screw rod and convex shaft of the supporting frame and a first light source. A heaven body ball is a transparent round ball with a hollow inner space, a heaven body map is depicted thereon. Holes are installed on the upper and lower ends thereof for being inserted by the fixing stud on the lower end of the engaging rod and for being passed through by the first light source and then the first light source will be positioned on the ball pad so to be assembled between the supporting frame and the seat. Therefore, by the touch controlled light emitting two balls instrument within the seat to control the switching of the two light sources, a four stages illumination effects will be generated.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.
