SOLAR-EARTH-MOON ASSEMBLY ALLOWING DESCRIPTION OF CHANGE OF TIME AND SEASON ACCORDING TO LOCATIONS OF LATITUDE AND LONGITUDE OF OBSERVER

摘要

The present invention relates to a solar-earth-moon assembly enabling a user to understand processional motion and to easily and intuitively observe and understand the change of the time and the season at a latitude and a longitude where an observer is located. According to the present invention, the solar-earth-moon assembly includes a solar model, a globe, a lunar model, a lunar phase shift plate, an earth date conversion plate, and a precession rotation plate. The globe is coupled to the solar model while being spaced apart from the solar model through an earth-sun coupling part and arranged to revolve around the solar model. The lunar model is coupled to the globe through a moon revolution axis so that a lunar model can revolve around the globe. The lunar phase shift plate is arranged under the globe. The earth date conversion plate is arranged over the lunar phase shift plate. The precession rotation plate is interposed between the earth date conversion plate and the glove, has a scale marked on an outer circumferential surface thereof, and allows a user to recognize procession between two mutually different time points as the procession rotation plate rotates clockwise or counterclockwise. The globe is coupled to the procession rotation plate to rotate about an earth rotation axis, and the lunar phase shift plate, the earth date conversion plate, and the precession rotation plate are coupled to a rotation plate rotation axis to coaxially rotate about the rotation plate rotation axis. Observation insertion holes are recessed in mutually different latitudes and longitudes on the surface of the globe. The globe has at least one observation dummy to observe the change of the time and the season at an observer location as the at least one observation dummy is inserted into the observation insertion hole.;COPYRIGHT KIPO 2016
