Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is a gardening method in which a house-shaped frame is covered with a sheet, and a field suitable for cultivating or growing vegetables, fruits, flowers, etc. is created within the frame. This invention relates to a ventilation system in a commercial house.

[Conventional technology]

This type of house generally has a frame with an arch-shaped roof frame continuous on top of pipe columns, a roof sheet placed over the roof frame, and a roof sheet that hangs down from the eaves of the roof frame along the column on the girder side. The house is equipped with a side sheet, a front sheet, a back sheet on the gable side, and an entrance/exit door on the front sheet.The ventilation system installed in this house generally opens the side sheet from below, like a curtain on a stage. They are tied up with string at intervals, tied to the frame at the top, and vents are left open on the sides.

[Problem that the invention seeks to solve]

The length of the rows of gardening greenhouses ranges from as short as around 10m to as long as 100m to 150m, and for agricultural use, many are rather long. In either case, the side sheets are manually rolled up from the end by the worker, and then tied up in sequence with strings attached to the girders at appropriate intervals. Even in such cases, a large number of strings must be untied one by one, and this operation is extremely troublesome and time-consuming, and also takes a surprisingly large amount of time.

This is especially troublesome and time-consuming for houses with a long length of 100 to 150 m, and has the disadvantage that it cannot be completed in time if urgent needs are required.

The purpose of this invention is to solve the above-mentioned problems, and to provide a ventilation device for a gardening greenhouse that can easily and quickly open and close an opening for controlling the temperature or ventilating the inside of the greenhouse. There is a particular thing.

[Means for solving problems]

The ventilation device for a gardening greenhouse according to the present invention is provided with an opening and closing opening using a slide fastener extending in the column direction in the vertically hanging part of the upper part of the side sheet of the greenhouse, and an operation system that is constructed so that it can be moved freely along the opening and closing opening. The slider of the slide fastener is connected to the strip.

〔Effect of the invention〕

If the aeration device for a gardening house according to the present invention is adopted, (1) a slider is connected to an operating strip constructed along the opening/closing opening, and by pulling the operating strip, the slider slides to open/close the opening/closing opening for ventilation; Since the door can be opened and closed, there is no need for the worker to walk along the house when opening and closing the door, and the operator can open and close the vent on the side of the house along the entire length while standing in one corner of the house. Because it is possible to
It is easy to open and close the opening for ventilation.

(2) Since the opening/closing opening using the slide fastener is provided in the part that hangs vertically at the top of the side sheet, the slide fastener of the opening/closing opening does not come into pressure contact with the frame of the house due to the weight of the seat, and the slider Since sliding is not obstructed, the slide fastener can smoothly open and close a large side sheet even when the sheet is suspended.

(3) The operation rod is moved to slide the slider and open the slide fastener to open the side seat opening. At this time, the seat opening/closing opening by the slide fastener hangs vertically at the top of the side seat. Since the lower seat part separated by the slide fasteners of the side seat lowers under its own weight at the same time as the slide fasteners are opened, the seat opening/closing opening can be opened simultaneously with the slide fasteners. The opening and closing opening can be opened and closed at once.

Furthermore, when closing the expanding opening with the slide fastener, the load acting on the slider is light and only the weight of a portion of one side of the lower seat portion acts. Since the resistance force acting on the slider when closing the slide fastener is surprisingly small as it is pulled up sequentially from one side, the opening/closing opening of the side seat is expanded and the vent opening is closed only on the lower seat. The slider is then simply slid in the direction of closing the fastener by means of the operating rod, and the operation of pulling up the lower seat portion and closing the opening/closing opening are performed all at once.

Therefore, the ventilation holes in the side sheets of the house can be opened and closed easily and quickly.
