Abstract: PROBLEM TO BE SOLVED: To provide a greenhouse curtain device capable of stretching curtain members in double layer with an easy structure, forming an air layer between each curtain member, and further increasing heat insulation effectiveness. SOLUTION: This greenhouse curtain device has a lower rack wire 19 below an upper rack wire 18 which supports an upper layer curtain member 30, and comprises letting the lower rack wire 19 support a lower layer curtain member 40 to form an air layer between the upper layer curtain member 30. The lower layer curtain member 40 is opened and closed together with the upper layer curtain member 30. Since a mechanism to operate the upper layer curtain member 30 functions as a mechanism to open and close the lower layer curtain member 40, it is possible to make a double layer type with a minimal number of parts and increase heat insulation effectiveness by the air layer.

Abstract: PROBLEM TO BE SOLVED: To provide a device for opening and closing a curtain for a greenhouse, capable of extending a curtain member so as to completely close the upper part in the greenhouse. SOLUTION: This device 1 for opening and closing the curtain for the greenhouse is constituted of a guide member 2 arranged so as to be hung in the greenhouse, a leading member 4 installed along the direction nearly crossing the guide member 2, and moved in the direction along the guide member 2 by the drive of a driving wire 5, a curtain member 3 covering the guide member 2, joined to the leading member 4 at the tip part 3a, and opened and closed by being expanded and contracted according to the movement of the leading member 4, and a clip 6 for connecting the leading member 4 and the driving wire 5. The clip 6 can be moved with the driving wire 5, and can relatively be slid on the driving wire 5 when a prescribed value or more of the force for blocking the movement is applied thereto.
