Abstract:
1. A multi-functional shading device, comprising: a top traverse supporter; a first shading arrangement downwardly extended form said top traverse supporter comprising a base member, a plurality of slats being horizontally and suspendedly supported between said traverse supporter and said base member, and a first operating means for selectively lifting up said base member towards said traverse supporter and unlifting said base member to drop downwardly away from said traverse supporter; a second shading arrangement comprising an upper supporter, a base stabilizer, a translucent fabric, which is folded in a Z-shaped manner, downwardly extended from said base member to said base stabilizer, wherein said first and second shading arrangements having different light intensity blocking abilities are adapted for selectively blocking lights passing through from one side to another side of said shading arrangements respectively; a mounting means for securely binding said first shading arrangement and said second shading arrangement so as to provide different light blocking effects, wherein said mounting means comprises an upper mounting member provided on said upper supporter to detachably attach on said base member so as to mount said second shading arrangement underneath said first shading arrangement; and a wind-proof arrangement which comprises a pair of sway-resisting guiding devices downwardly extended from two side portions of said top transverse supporter towards said base stabilizer of said second shading arrangement respectively for substantially restricting an unwanted lateral movement of each of said first and second arrangements from swaying back and forth; wherein said upper mounting member has a longitudinal mounting slot formed on said upper supporter, wherein said base member is slidably engaged with mounting slot to mount said upper supporter to said base member so as to securely mount said second shading arrangement below said first shading arrangement; wherein said second shading arrangement further comprises a second operating means which comprises a lift locker slidably mounted on said base stabilizer, a lift cord having a first end affixed to said base stabilizer and a second end affixed to said lift locker wherein said lift cord penetrates through two side portions of said translucent fabric and extends along said upper supporter, and a lift retaining device applying an urging force to said lift locker so as to retain said lift locker on said base stabilizer in position.
