Abstract
Abstract A horizontally mounted solar collector for collecting solar energy utilizing a vertical deflector assembly, a stationary reflector and a collector. The deflector assembly contains a plurality of vanes which change the direction of the solar energy to the vertical, while constantly keeping the same side of the deflector facing the sun. The vertical rays are then reflected off the stationary reflector and are then absorbed by the collector.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
117 words
A solar energy collection system comprising: (a) deflector means for receiving incident solar radiation and reflecting it downwardly in a vertical direction; (b) a reflector in the form of a paraboloid of revolution disposed beneath the deflector means for receiving the downwardly directed solar energy and reflecting it upwardly to a focus point; and (c) collector means at the focus point for collecting the solar energy; and (d) said deflector means including a plurality of moveable solar energy diverting vanes mounted on a plurality of cross beams which are positioned over the reflector and which extend as chords with respect to the reflector, the plurality of vanes being disposed between the cross beams, in rows perpendicular thereto.
Claim 2
Dependent Claim
117 words

Claim 3
Dependent Claim
19 words
A solar energy system in accordance with claim 1 further including means for changing the angles of said vanes.
Claim 4
Dependent Claim
119 words
A solar energy system in accordance with claim 2 wherein said means for changing the angles of said vanes includes: a drive shaft disposed across said deflector means; a means operatively connected to said drive shaft for powering said drive shaft; a drive chain operatively associated with each of said cross beams, each of said drive chains connected to said drive shaft; a plurality of vane position arms attached to and rotated by said drive chains; a plurality of vane position plates, each of said plates attached to one of said vane position arms; and flexible elongated means attached to each row of said vanes and said vane position plates for changing the angle of said plurality of vanes.
Claim 5
Dependent Claim
44 words
A solar energy system in accordance with claim 3 further including guide pins attached to each of said vane position plates and guide means in each of said cross beams, whereby said vane position plates are restricted to movement only in the vertical direction.
Claim 6
Dependent Claim
27 words
A solar energy system in accordance with claim 3 further including spring means attached between each of said vanes and said cross beams for tensioning said vanes.
Claim 7
Dependent Claim
23 words
A solar energy system in accordance with claim 3 further including adjustment bolts for maintaining said flexible elongated means in the current position.
Claim 8
Dependent Claim
132 words
A solar energy system in accordance with claim 2 wherein said means for changing the angles of said vanes includes: a drive spline shaft disposed across said deflector means; a means operatively connected to said drive shaft for powering said drive shaft; a drive chain operatively associated with each of said cross beams, each of said drive chains connected to said drive shaft; a plurality of van control arms attached to and extended and retracted by said drive chains; and a spring loaded roller means provided in each of said cross beams, each roller means being threaded by one of said diverting vanes for keeping each of said vanes at a predetermined tension and allowing said vanes to be extended in length by the unrolling of said vane from said roller means.
Claim 9
Dependent Claim
20 words
A solar energy system in accordance with claim 7 further including a protective cylinder surrounding said spring loaded roller means.
