CELESTIAL GLOBE

摘要

A celestial globe model includes several petal-shaped sheets and two circular sheets fabricated from transparent and flexible material. Each petal-shaped sheet has two opposite end portions respectively defining a notch and two long curved edges interconnected with corresponding long curved edges of an adjacent petal-shaped sheet to form a sphere like body with a circular opening confined by the notches. The inner surface of the sphere like body is formed with the first celestial coordinate pattern. The circular sheets are connected sealing to the peripheries of the notches of the petal-shaped sheets to form the sphere like body once inflated. Each circular sheet has an inner surface formed with the second celestial coordinate pattern. An inflate valve is mounted on one of the circular sheets for inflating and deflating the sphere-like body.

主权项

1. An inflatable celestial globe comprising:
a plurality of petal-shaped sheets fabricated from transparent and flexible material through Rectangular Polyconic map projection, each of said petal-shaped sheets having an inner surface and an outer surface opposite to said inner surface, each of said petal-shaped sheets further having two opposite end portions respectively defining a notch and two opposite long curved edges extending between said opposite end portions and interconnected with corresponding long curved edges of an adjacent petal-shaped sheet, thereby forming a sphere like body with a circular opening confined by the peripheries of said notches, wherein said inner surface of each of said petal-shaped sheets is formed with the first celestial coordinate pattern different from one another; and two circular sheets fabricated from transparent and flexible material and connected sealingly to the peripheries of said notches of said plurality of petal-shaped sheets in order to form the sphere like body once inflated, each of said circular sheets having an inner surface and an outer surface opposite to said inner surface, wherein said inner surface of each of said circular sheets is formed with the second celestial coordinate pattern.
