Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an insect net for a skylight that prevents pests from entering through a skylight attached to an agricultural greenhouse or an agricultural house.

[0002]

[Prior art]

 Conventionally, insect repellent nets have been attached to the skylights of agricultural greenhouses and agricultural houses so that pests that inhibit the growth of crops do not enter. As an example of the installation of the insect repellent net, for example, as shown in FIG. 6, an entire roof top provided with a skylight 20 is separated by an insect repellent net 22 to prevent the pests from entering. In addition, there is a problem that the structure is large and it takes time and effort for construction, and there is also a problem that the insect repellent net 22 is attached to the aluminum frame 24 and attached to the roof frame, so that the cost is high. Moreover, since the insect-repellent net 22 made of aluminum is partitioned in a saucer shape, dead bodies of insects such as moths and gold insects and leaves of trees are liable to accumulate, and translucency and ventilation are reduced. In the meantime, the insect repellent net 22 had to be cleaned, but because the roof of the agricultural greenhouse or agricultural house was high and required to work at high places, it was necessary to build a scaffold, increasing the cleaning cost and taking days. In some cases, the cultivation had to be stopped, which caused various problems.

[0003] Therefore, as shown in FIG. 7, a window opening 21 formed on the roof and a ceiling which is pivotally attached to one side edge of the window opening 21 so that the window opening 21 can be opened and closed by a skylight opening and closing mechanism. There has been proposed a skylight device including a window 20 in which an insect net 22 surrounding an opening formed when the skylight 20 is opened is attached between the skylight 20 and the window opening 21. In such a device, when the wind is blown while the skylight 20 is being opened and closed, the insect repelling net 22 is caught by the skylight 20 and the window opening 21, and when the skylight 20 is opened and closed, the insect repelling net 22 protrudes out of the rotation locus of the skylight 20. Since it is sandwiched between the skylight 20 and the window opening 21, there is a problem that the insect net 22 is broken, the opening and closing of the skylight 20 is hindered, and the skylight opening / closing mechanism 23 is broken. In order to prevent the insect net 22 from protruding outside the rotation trajectory of the skylight 20, attempts have been made to make the insect net fold in a bellows shape as the skylight is opened and closed. In order to be able to fold it, there are problems that the structure is complicated and expensive, and the construction work is troublesome.

[0004]

[Problems to be solved by the invention]

The insect repelling net 6 is installed between the windows and surrounds the opening when the skylight 4 is opened. As shown in FIG. 5, the insect repelling net 6 has a square front surface and a tapered triangular shape on both sides. It has a U-shaped cross section. The insect net 6 is attached to the insect net mounting frame 7 attached to the frame material forming the window opening 3 at the rooftop, with the lower end of the front and both sides of the three side edges. Is attached to the same insect repellent net mounting frame 7 having the upper end attached to the lower surface of the frame of the skylight 4. As shown in FIG. 2 and FIG. 3, the insect-removing net mounting frame 7 has a spring clip (not shown) fitted in a rim-shaped receiving rail. After pushing, the insect clip 6 is attached to the receiving rail by pushing the spring clip into the receiving rail.

Reference numeral 9 denotes holding means for supporting an intermediate portion of the insect-controlling net 6 and preventing the insect-controlling net 6 from always protruding largely outside the rotation locus of the skylight 4. The holding means 9 includes an intermediate holding frame 7a provided in the lateral direction along the middle of the front surface of the insect repelling net 6, and an intermediate portion of the insect repelling net 6 supporting the intermediate holding frame 7a so that the skylight 4 always rotates. It is composed of a support member 10 for preventing it from protruding outside the trajectory. The intermediate holding frame 7a cuts or bends the roof frame 1a to prevent the intermediate holding frame 7a from hitting the roof frame 1a when the skylight 4 is closed and lowered. As shown in FIG. 5, the intermediate holding frame 7a has bent portions 7b on both sides, and the bent portions 7b extend to both side surfaces of the insect-repelling net 5, whereby both sides of the insect-repelling net 6 are formed. The triangular portion is prevented from being caught on the skylight 4 or the like. Even when the bent portion 7b is provided, it is not necessary to provide the tapered tips of the triangular portions on both sides of the insect repellent net 6, but only at the base of the triangular portion where the catch is likely to occur. The supporting member 10 shown also serves as the opening / closing arm 5a of the skylight opening / closing mechanism 5, and the opening / closing arm 5a supports the intermediate holding frame 7a in a freely movable manner. The floating member 11 has the intermediate holding frame 7a movably attached to the opening / closing arm 5a by sandwiching the opening / closing arm 5a of the skylight 4 and attaching the U-shaped bolt 11a to the intermediate holding frame 7a. . As shown in FIG. 3, a frictional resistance reducing member 15 for improving the slip is interposed between the opening / closing arm 5a and the intermediate holding frame 7a.

In other words, if the intermediate holding frame 7a and the opening / closing arm 5a can move freely. Good. In the drawings, reference numeral 13 denotes a mounting bracket for fixing the frame 2a of the transparent covering material 2 to the house main body 1, and 14 denotes a mounting bracket for fixing the ridge 5 to the house main body 1.

With the above-described structure, when the room temperature rises, when the room temperature is lowered, if the electric or manual skylight opening / closing mechanism 5 is driven, the opening / closing arm 5a of the skylight opening / closing mechanism 5 becomes The window 4 is lifted up through a link mechanism (not shown) to open the skylight 4. In a state where the skylight 4 is fully opened or has an arbitrary opening amount, the window opening 3 opened by the skylight 4 has an upper edge attached to a lower edge of the skylight 4 via an insect-proof net attachment frame 7, and a lower portion. Since the edge is closed by the insect screen 6 attached to the lower surface of the window opening 3 of the roof via the insect screen attachment frame 7, it is possible to surely prevent pests from entering through the open window opening 3. Becomes

Moreover, since the insect-preventing net 6 is stretched slightly inward with respect to the front window opening 3 by the holding means 9, it is difficult for the insects to adhere and the insects are deposited. Can be reliably prevented. Further, even if the insects adhere, the insects easily fall due to the opening / closing operation or the wind, so that the ventilation and translucency of the insect repellent net 6 do not decrease. When the room temperature is lowered due to cloudiness at night or when the electric or manual skylight opening / closing mechanism 5 is driven to rotate in the reverse direction, the opening / closing arm 5a of the skylight opening / closing mechanism 5 is connected via a link mechanism (not shown). And the skylight 4 is closed. When the insect window 6 is closed, the insect repelling net 6 is supported by the intermediate holding frame 7a as the holding means 9 and the supporting member 10 so as not to go out of the rotation locus of the skylight 4. This is to prevent the net 6 from catching on the skylight 4 and causing the opening and closing of the skylight 4 to fail, or to prevent the insect repellent net 6 from being damaged by closing the skylight 4 while being hooked on the skylight 4. Moreover, when the skylight 4 is closed, the intermediate holding frame 7a, which is the holding means 9 which is movably attached to the opening / closing arm 5a as the supporting member 10 and holds the insect net 6, has the roof frame 1a of the house body 1 cut away. Since the intermediate holding frame 7a can descend over the roof frame 1a with the closing operation of the skylight 4, the insect repelling net 6 is always stretched under tension. 6 does not become entangled.

In the preferred embodiment, the holding means 9 for preventing the insect net 6 from coming out of the rotation locus of the skylight 4 is provided with a holding means 9 of the insect net 6 attached to an intermediate portion of the insect net 6. An intermediate holding frame 7a provided in the lateral direction along the middle of the front surface, and a supporting member that supports the intermediate holding frame 7a and prevents the intermediate portion of the insect net 6 from constantly protruding outside the rotation locus of the skylight 4. Although the holding means 9 may be directly hung from the insect window 6 by a wire, a string or the like, which is hung from the skylight 4, the insect net 6 may be hung from the skylight 4. In order not to cross the rotation locus of the wire, it is preferable that the wire or string as the holding means 9 is stopped so as to be drawn into the inside of the skylight. Through 7 Needless to say, it is also possible to attach them.

[Effect of the invention]

 As apparent from the above description, the present invention attaches an insect repellent net between the window opening formed on the roof and the skylight and surrounds the opening formed when the skylight is opened, and also includes an insect repellent net. A holding means was provided to partially support the front part to prevent the skylight from protruding outside the rotation locus of the skylight at all times, so that an insect repellent net could be set up at low cost, and dead insects and leaves of trees would accumulate. The insect repellent net does not fall out of the rotation locus of the skylight by the holding means, so that the insect repellent net may be caught on the skylight and damage the insect repellent net. It does not cause the opening and closing of the skylight. In addition, the holding means in such a insect window for a skylight is provided with an intermediate holding frame provided in the lateral direction along the middle of the front portion of the insect window, and an intermediate portion of the insect insect net supporting the intermediate holding frame is always a skylight. With the support member that prevents it from protruding outside the rotation trajectory, it is extremely easy to remove and replace only the insect repellent net, and furthermore, it is attached to the middle of the front part of the insect repellent net. If the two sides of the intermediate holding frame provided in the horizontal direction are bent and extended to both sides of the insect repellent net, the insect repellent net on the side of the skylight is prevented from going out of the path of rotation of the skylight. Does not cause breakage of the net or poor opening / closing. In addition, if the supporting member is an opening / closing arm of a skylight opening / closing mechanism and the intermediate holding frame is movably supported by the opening / closing arm, it can be installed in a conventional agricultural greenhouse or agricultural house without using a new supporting member. It can be attached and remodeled at low cost, and the insect repellent net can be reliably folded.Moreover, during opening and closing operation, a strong tensile force is not applied to the insect repellent net, so that it can be more accurately prevented from being damaged. It has the advantage of: Therefore, the present invention is of great practical value as an insect net for skylights that has solved the conventional problems.
