Document Type and Number:
WIPO Patent Application WO/2012/087019
Kind Code:
A3
Abstract:
The present invention relates to a 2-axis tracking apparatus, and to a 2-axis tracking apparatus for a sunshade apparatus having a plurality of frame slats (S2) and one or more mini slats (S1) fitted to the respective frame slats (S2) to be rotatable, wherein the 2-axis tracking apparatus comprises: mini slat angle adjusting means for adjusting the angles of the mini slats (S1); frame slat angle adjusting means for adjusting the angles of the frame slats (S2); first power transmission means for transmitting power to the mini slat angle adjusting means; and second power transmission means for transmitting power to the frame slat angle adjusting means. The first power transmission means and the second power transmission means act on the respective mini slat angle adjusting means and the frame slat angle adjusting means independently of each other without a mutual interference. The rotating directions of the frame slats (S2) and the rotating directions of the mini slats (S1) fitted to the frame slats (S2) intersect with each other. The 2-axis tracking apparatus of the present invention may precisely track both of a solar azimuth angle and a solar altitude angle while performing a unique sunshade or lightening function of a sunshade apparatus. The 2-axis tracking apparatus of the present invention may be installed anywhere, maximizes solar energy use efficiency, has a simple structure to allow for ease of installation, is not bulky which enables installation of the apparatus in an indoor area, and may be manufactured in an inexpensive manner.
