The case 2, the first positioning ring 3, the second positioning ring 4 and the pole 5 may be made of material selected from the light-weighted metal, such as the iron plate, the aluminum alloy, the titanium alloy, or the hard reinforced plastic.
Referring to FIGS. 3 to 7, the operation procedure of the embodiment is described as follows.
Before operation, referring to FIG. 3, the first positioning ring 3, the second positioning ring 4 and the pole 5 are all parallel to the case 2 without any angle alteration.
In the operation, the procedure for setting is described as follows. Referring to FIGS. 4 to 6, first of all, the first positioning ring 3 is set according to the location (latitude) of the observation station (FIG. 4). The rotation of the first positioning ring 3 corresponds to the latitude graduation 22 marked on the outer side of the case connected to the two distal end of the axle 31 of the first positioning ring 3. The hand 24 is adjusted to align with the scale of the local latitude 22, then the first positioning ring 3 is secured by the positioning portion (not shown) to stop the rotation of the first positioning ring 3. Furthermore, the second positioning ring 4 is rotated according to the observation time (hour). Referring to FIG. 5, the rotation of the second positioning ring 4 corresponds to the time graduation 32 (24 hours) marked on the outer surface of the first positioning ring 3 connected to the two distal ends of the axle 41 of the second positioning ring 4. The regulator hand 33 is adjusted to align with the scale of the local observation time (24 hours), then the second positioning ring 4 is adjusted by the positioning portion (not shown) to stop the rotation of the second positioning ring 4. Finally, the pole 5 is moved according to the date (season) of the observation as illustrated in FIG. 6. The pole 5 is moved according to the date (season) scale 44 marked around the groove 42 of the second positioning ring 4 and securing the pole 5 by the positioning portion (not shown) to stop the motion of the pole 5 when the pole 5 moves to align with the observation date (season) scale. In the embodiment of the present invention, the positioning portion may be comprised of a screw, a hook or a stopper.
The above setting steps are based on the earth revolution track and the earth rotation order. As the sunlight illuminates on various parts of the earth surface with various latitudes, the motion track can be categorized into three types, the 24-hour daily alternation concerning sunrise and sunset, 365-day yearly alternation of which concerning the change of seasons, and the less significant and ignorable precession and nutation of the earth rotation. The time setting step is based on the daily alternation; the earth rotation generally causes the sunrises and the sunsets, the time to be concluded as a day is when the sun passes the meridian twice continuously, and it's called the solar day. The solar day may be further divided into 24 hours, therefore the embodiment of the present invention needs to set the time. Furthermore, the step for setting the date (season) is based on the yearly alternation. The sun not only proceeds self rotations but also solar revolutions. A cycle of the revolution is called a year, and the motion of the earth goes along the track plane of the solar revolution is called the ecliptic plane. The direction of the plane normal of the ecliptic plane is positioned at an angle (about 23.5 degree) to the earth self-rotation axle, and the angle is called inclined angle of the earth rotation axle. The inclined angle enables the sun directly illuminate on the northern hemisphere in the summer and oblique illumination on the earth surface in the winter to create the seasonal alternation, the hot summer and the cold winter. The embodiment of the present invention thus requires for setting the date (season).
Referring to FIG. 7, the above steps for setting latitude, time and date (season), the azimuth graduation 23 of the case 2 is arranged according to the local orientation in operation, and the direction thereof can refer to the compass. The canopy 1 is placed and data as well as documentation are read for the solar azimuth and the elevation angle according to the azimuth graduation 23 of the case 2. Meanwhile, the sunlight directly enter through the through hole 51 of the pole 5 and further penetrates through the hollow pole 52 to directly illuminate on the sight 53. The user can set a laser indicator pen 55 (FIG. 2) in the through hole 51 or the sight 53 of the pole 5, and thereby learn the azimuth and the elevation angle of the sun corresponding to the canopy 1. The laser indicator pen 55 can be inlayed or screwed to an inner side of the through hole 51 or on the sight 53. By repeating the above steps for recording each orientation of the sun in orderly manner on the canopy 1 can substantially conclude the data of the solar trajectory.
Furthermore, the present invention can be applied for simulating the solar trajectory track, and the steps of the procedure are the same as the above embodiment except for the setting of the solar orientation of the location, time and season can be random without referring to the local latitude and longitude, time and season. After completing the setting, a laser indicator pen 55 is installed in the through hole 51 or on the sight 53 of the pole 5 to learn the azimuth and the elevation angle of the sun corresponding to the canopy 1. The laser indicator pen 55 can be inlayed or screwed to an inner side of the through hole 51 or on the sight 53. By repeating the above steps of recording each orientation of the sun in orderly manner on the canopy 1 can substantially conclude the data of the solar trajectory.

The flange of the second positioning ring 4 has a through hole 45 extending to the central of the second positioning ring 4 and has a sight 46 therein. The operation procedure of this embodiment is described as follows. The first positioning ring 3 is rotated to a required angle according to the local latitude, the second positioning ring 4 is rotated for further setting the observation time. Thus, by setting the location and time, the sunlight directly illuminates onto the sight 46 after penetrating through the through hole 45 of the second positioning ring 4, the azimuth and the elevation angle of the sun can be observed.
