    Abstract: PROBLEM TO BE SOLVED: To provide a ventilation apparatus for a greenhouse designed so as to prevent such malfunction that a ventilation member is kept open at a prescribed open angle due to unintended movement of an operative mechanism. SOLUTION: The ventilation apparatus for greenhouse is installed in the main body part 2b of the operative mechanism 2. The main body part 2b is provided with a movable member 9 movable up and down independent of the main body part 2b, a push spring 11 intervening between the movable member 9 and the main body part 2b and energizing the movable member 9 in its descending direction, a guide pin 7 installed at the front edge part of a locking member 6, and a path 10 which is formed in the movable member 9 and through which the guide pin 7 is movably inserted. The path 10 has a first area 10a in which the guide pin 7 is engaged to inhibit the locking member 6 from rotating in one direction, and a second area 10b communicating with the first area 10a to rotate the guide pin 7 getting out of the first area 10a. Further the apparatus is provided with a first linear member 12 connected to the movable member 9 and pulled to move the movable member 9 in its rising direction. COPYRIGHT: (C)2008,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide a simply structured driving gear for a greenhouse saving labor in driving a member to be driven in the greenhouse. SOLUTION: The driving gear for a greenhouse has the following mechanism: materials to be driven are expanded due to temperature rise in the greenhouse in such a condition that a first engaged part 51b formed at a rock plate 50 is engaged with an engaging pin 12a of an actuator 10; a traveling member 30 moves in one direction along a support frame 20 when a piston 12 is elongated relative to a cylinder 11; an end window 100 joined via an arm 40 automatically opens in accordance with temperature change; and the travelling member 30 moves in a direction opposite to the above-mentioned one to close the end window 100. An automatic operation mode and a manual operation mode can be easily switched over only through selecting whether or not to make the first engaged part 51b of the rock plate 50 and the engaging pin 12a engage with each other.

    Abstract: PROBLEM TO BE SOLVED: To provide a driving apparatus for a greenhouse saving labor in driving a member which is the object of operation in the greenhouse. SOLUTION: The driving apparatus for the greenhouse comprises an actuator 10 provided with a cylinder 11 filled with a driving material changing the volume corresponding to temperature and a piston 12 sliding in the cylinder 11. The piston 12 is connected to a thermally driven arm 32 connected to the member which is the object of the operation and the cylinder 11 is fixed and arranged in a supporting frame 20. When the temperature is increased, the driving material is expanded to push out and elongate the piston 12. Thereby, the thermally driven arm 32 is rotated. A connecting arm 40 is rotated through an actuating arm 33 and a rotating shaft 31 by rotating the thermally driven arm 32. Thereby, the member which is the object of the operation is operated. The actuating arm 33 can manually be operated irrespective of the elongated state of the piston 12 by releasing the engaged state of the thermally driven arm 32 with the actuating arm 33.
