手と時間がかかるという問題があった。2. Description of the Related Art Conventionally, a greenhouse skylight opening / closing device for opening and closing a large number of parallel skylights interlocks with each other. It was usual to open and close the skylight by. However, since the link mechanism is operated by the small-diameter shaft pipe to open and close the skylight, the reduction ratio of the motor increases and it takes time to open and close. In addition, since a plurality of link rods are attached to the skylight, there is a problem that the assembling work is troublesome and time consuming, and the weight is large and the power consumption increases. Moreover, there has been a problem that the long-term use causes wear on the pivot portion where the load is concentrated, resulting in poor opening and closing of the skylight. In order to solve such a problem, a device for opening and closing the skylight by a rack and pinion mechanism has been proposed, but in the case of the rack and pinion mechanism, a series of shaft pipes for driving are suspended below the skylight and A pinion is driven by a pipe, and a rack meshing with the pinion is slid to open and close a skylight pivotally attached to one end of the rack. Therefore, if the rack teeth of each rack and pinion mechanism corresponding to each skylight and the position of meshing of the pinion teeth do not match, opening and closing of many skylights will be inconvenient. It was absolutely necessary to align the meshing position. However, since the rack and the pinion are housed in an integrated case, there is a problem that the meshing alignment is extremely difficult and takes a lot of manpower and time.

The opening and closing operation of each skylight 2 is performed by rotating the square shaft 11 by a drive source (not shown), and the rotation and locking of the square pin 11 and the square hole 4c of the barrel 4a are locked. The pinion 4 of the mechanism 3 is rotated by the rotation of the square shaft 11, and the pinion 4 formed on the barrel 4a is rotated. The rack 6 having the teeth 9 meshing with the teeth 8 of the pinion by the rotation of the pinion 4 is guided by the roller 7a of the rack case 7 to slide. Since the rack and pinion mechanism 3 is held around the square shaft 11, the rack 6 slides to open and close the skylight 2, which is pivotally attached to the rack 6 to adjust the temperature inside the greenhouse 1. However, in order to assemble the present invention into the greenhouse 1, first, the rack case 7 and the pinion case 5 of the rack and pinion mechanism 3 are separated and the skylight is provided over the entire length of the greenhouse 1. The number of pinions 4 of the rack and pinion mechanism 3 is fitted into the square shaft 11 suspended below 2 through the square holes 4c of the shaft cylinder 4a.

The position of the rack tooth 9 that meshes with the pinion tooth 8 is checked from the number of teeth in the closed state. When the tooth position can be set in this way, the rack case 7 is fitted into the lower opening of the pinion case 5, and the lower surface of the rack 6 is guided and supported by the rollers 7a.
Are fixed with bolts 10. Next, the next rack and pinion mechanism 3 that opens and closes the adjacent skylight 2 is arranged at the mounting position of the angular shaft 11. Then, in the same manner as described above, the rack 6 having one end pivotally attached to the skylight 2 is fitted and inserted from the lower opening of the pinion case 5, and the position of the rack tooth 9 that meshes with the pinion tooth 8 with the skylight 2 closed. After checking the number of teeth and engaging them, the rack case 7 is fitted into the lower opening of the pinion case 5 and fixed by the bolt 10. Less than,
In the same manner as described above, the rack and pinion mechanism 3 may be attached to each skylight 2, and the rack and pinion mechanism 3 attached in this way is driven to confirm the opening and closing operation of the skylight 2 and to open and close the skylight 2. If it is not smooth, the rack case 7 of the rack and pinion mechanism 3 of the skylight 2 having a problem in the movement is removed, and the rack teeth 8 and the pinion teeth 9 are removed.
It suffices to correct the meshing position with so that an appropriate opening / closing operation can be obtained.

して業界の発展に寄与するところ大なものである。As is apparent from the above description, the present invention employs the rack and pinion mechanism, so that the weight can be reduced and the driving force can be reduced, so that the power consumption can be suppressed.
In addition, since the rack case and pinion case can be attached and removed freely, the meshing position of the rack teeth and pinion teeth can be extremely easy, and the assembly time and the number of workers can be reduced. The adjustment after assembly can be easily done and the opening / closing operation of the skylight can be set to the smoothest state, which enables long-term durability and reduces the running cost. Also, since the square hole of the pinion is locked to the square shaft for driving the pinion, unlike the case where the circular hole of the pinion and the circular shaft are locked, slipping does not occur and the driving force can be reliably applied to the pinion. It has various advantages such as transmission. Therefore,
INDUSTRIAL APPLICABILITY The present invention greatly contributes to the development of the industry as a greenhouse skylight opening / closing device that solves the conventional problems.
