Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an aeration system for a horticultural greenhouse called a tunnel or greenhouse used for cultivating or growing vegetables, fruits, flowers, etc.

[Conventional technology]

Taking a tunnel as an example of a horticultural greenhouse, the one disclosed in Japanese Utility Model Publication No. 1148/1983 published by the applicant is known. The technical content is that in order to solve the trouble of conventionally having to pull up the tunnel seat from the hem to open the ventilation hole, we have created an opening with a slide fastener along the entire length of the seat. This allows the vent to be opened and closed by means of a holder, thereby simplifying the operation of opening and closing the vent.

[Problems to be Solved by the Invention] According to the tunnel in which the vent opening is opened and closed by the aforementioned slide fastener, the opening and closing operations of the vent opening can be performed easily and quickly. However, in recent years, tunnels and greenhouses have become extremely long and tall, making it difficult to reach depending on the mounting position of the slide fasteners, making it extremely difficult to open and close the vents. Also, when opening and closing the slide fastener, you only need to slide the slider,
If the tunnel is long, you will have to move the slider while walking along its entire length. However, it was difficult.

Furthermore, the sheet placed over the greenhouse has some sagging between the aggregates that make up the frame, and is tensioned in a chevron shape at the aggregate parts, and the slide fasteners attached to this sheet also exhibit a wave shape. . In this state, when a slider with a slide fastener installed on it is slid to open or close, the slider hits the aggregate at the chevron-shaped part of the aggregate and is prevented from sliding. However, when the slide fastener is under tension, the slider slides smoothly, but as mentioned above, between the two aggregates, the sheet and the Because the slide fastener loosened, it was necessary to perform the troublesome operation of sliding the slider with one hand while straining with the other.

The purpose of this invention is to solve the above-mentioned problems. When opening and closing the sheet opening, it is no longer necessary for the operator to open and close the opening while walking along the greenhouse. The entire length of the greenhouse can be easily opened and closed, and the slide fastener attached to the opening can be operated remotely without getting caught on the frame of the greenhouse.
Another object of the present invention is to provide a ventilation device for a horticultural greenhouse, which is capable of smoothly opening and closing while applying tension to a slide fastener.

[Means for solving problems]

The ventilation device for a horticultural greenhouse according to the present invention is a horticultural greenhouse in which a frame made of a plurality of aggregates is covered with a sheet. A guide strip is installed along the opening and closing opening and facing away from the opening, and a slider for opening and closing the slide fastener is movably engaged with the guide strip, and the slider has a length longer than the opening and closing opening. This is a combination of operating sections.

A guide strip 6 made of wire is installed between the poles 5, 5 so as to face each other at a distance from above the slide fastener 3 and under tension, and the slider 7 of the slide fastener 3 is attached to this guide strip 6 as shown in FIG. As shown in slider 7
The guide strip 6 is inserted into the hole 9 of the handle 8 and is engaged in a suspended state so as to be movable, and the slider 7 is further connected to operating strips 10, 10 consisting of a pair of strings longer than the length of the tunnel. and each operation article 1
0 and 10 are extended in the longitudinal direction of the tunnel.

According to this embodiment, when the operating strip 10 at hand near the pole 5 is pulled, the slider 7 slides while being suspended from the guide strip 6 while maintaining its supporting height. Since the slide fastener 3, which is loosened downward between the aggregates, is pulled up and tensed, the slider 7 is smoothly slid to open or close the opening/closing opening 4.

The example shown in FIG. 4 is almost the same as the example shown in FIG. At the starting end, the other one is disposed in the middle in the length direction, and is provided so that when both sliders 7, 7 slide in the same direction, they operate in the same way, that is, both open or close. , 7 are engaged with a guide strip 6 installed above, both sliders 7, 7 are connected to each other by a connecting strip 11, and operating strips 10, 10 are fixed to each slider 7, 7, respectively. . Further, as the slide fastener 3, one long slide fastener 3 may be attached over the entire length of the opening/closing opening 4, or two slide fasteners may be attached in succession.

In this example, the slider 7, 7 opening/closing opening 4
The opening/closing opening 4 is opened and closed over the entire length by sliding half of the total length of the slider 7, and the number of sliders 7 is not limited to two, but a plurality of sliders 7 may be provided. In this case as well, the slide fastener is opened and closed with tension.

In the example shown in FIGS. 5 to 7, two opening/closing openings 4 formed by slide fasteners 3 are provided in the seat 2 in parallel to the side position slightly from the top part, similar to the above-mentioned examples, and each slider 7 , 7 is guide line 6,
