Adjustable shade greenhouse device

摘要

An adjustable shade greenhouse device selectively controls light exposure within a greenhouse. The device includes a frame having spaced cross members arching between lateral sides of the frame. Outermost cross members are positioned at respective ends of the frame. Spacers are each coupled to outermost cross members and spaced longitudinal supports are coupled to and extend between associated pairs of the spacers such that each longitudinal support extends along the frame in inwardly spaced relationship to the cross members. An interior cover is supported by the longitudinal supports. A shade has a lower edge coupled to one of the lateral sides of the frame. A transport bar coupled to the frame is selectively movable along the cross members with a top end of the shade wherein the shade is selectively extendable and retractable over the frame by movement of the transport bar.

1. An adjustable shade greenhouse device comprising:
a frame having a first end, a second end, a pair of spaced lateral sides extending between said first end and said second end, and a plurality of spaced cross members, each cross member arching between said lateral sides of said frame, said spaced cross members comprising a pair of outermost cross members, each outermost cross member being positioned at an associated one of said first end of said frame and said second end of said frame; a plurality of spacers, each spacer having a first end coupled to an associated one of said outermost cross members; a plurality of spaced longitudinal supports, each longitudinal support being coupled to and extending between an associated pair of said spacers such that each longitudinal support extends from said first end of said frame to said second end of said frame in inwardly spaced relationship to said cross members; an interior cover extending across and being supported by said longitudinal supports; a shade having a lower edge coupled to one of said lateral sides of said frame; a transport bar coupled to said frame transverse to said cross members, said transport bar being selectively movable along said cross members between said lateral sides of said frame, a top end of said shade coupled to said transport bar wherein said shade is selectively extendable and retractable over said frame by movement of said transport bar; an axle extending from said first end of said frame to said second end of said frame, said axle being coupled to said transport bar, said axle being positioned parallel to said transport bar; a plurality of gears, each gear being coupled said axle a plurality of tracks, each track being coupled to and extending along an associated one of said cross members, each gear engaging an associated one of said tracks wherein rotation of each said gear moves said transport bar along said associated cross member; and a plurality of rollers, each roller being coupled to said axle and said transport bar, each said roller abutting an associated one of said cross members opposite an associated one of said gears wherein said roller holds said associated gear in engagement with said associated track.
