Description

  The present invention relates to a net intrusion prevention tool for preventing an insect net that is provided at an opening of a window installed in a greenhouse from entering an indoor side.

  In a greenhouse used for cultivation of agricultural crops, it is necessary to manage the room at a temperature suitable for the crop, and a window for ventilation is installed.

  In the case where such a window is provided, an insect-proof net for preventing the invasion of pests into the room or preventing the beneficial insects from escaping to the outside is extended at the opening of the window. As described above, when the insect net is provided in the opening of the window, the window may be closed when the window is closed with the insect net entering the room due to factors such as wind.

  At this time, if the insect net is wet with rainwater, there is a problem that rainwater enters the interior of the greenhouse. When rainwater enters the greenhouse, the crops in the greenhouse may be rotted and may adversely affect the crops.

  In order to cope with such problems, insect repellents that push out the insect repellent net to prevent the insect repellent net attached to the opening of the openable skylight of the greenhouse from entering inside the opening of the skylight when the skylight is closed. A net projecting device has been developed (see, for example, Patent Document 1).

  The insect net extension device includes a fixing portion attached to a window tip rail near the skylight tip and an extrusion portion connected to the fixing portion via a coil spring portion, and the coil spring portion can be freely deformed by elasticity. It is like that. As a result, the insect repellent net overhangs the insect repellent net from the inside to the outside due to the elastic deformation of the coil springs in the direction of the spring against the slack of the insect repellent net that changes as the skylight opens and closes. When the skylight is closed, the insect net is prevented from being caught inside the greenhouse.

  The insect net extension device of Patent Document 1 has no problem in that it has an effect of preventing the insect net from being caught in the indoor side of the greenhouse.

  However, since the coil spring part of Patent Document 1 is elastically deformed in any direction against the slack of the insect repellent net that changes due to the opening and closing of the skylight, the coil spring part is fatigued every time the skylight is opened and closed. There was a risk of damage. Further, since the insect net extending device of Patent Document 1 always projects the insect net, the force pushed from the insect net side is transmitted to the fixed part through the extruding part and the coil spring part and used for a long time. There was a risk of breaking from the root of the coil spring.

  Therefore, when the window is closed, the insect-proof net can prevent the intrusion into the indoor side of the greenhouse, and the net intrusion prevention tool that does not get tired even when the opening and closing of the window is repeated and is not easily damaged is provided.

  Means for solving the above problems include an opening side frame of a window frame of a window whose one end is swingably attached to a mounting frame attached to a greenhouse, and an opening side bar of the mounting frame facing the opening side frame. In the net intrusion prevention tool that prevents the insect nets that enter between the inside of the greenhouse, the upper end is attached to the inside of the greenhouse than the insect nets on the opening side of the window frame, and always An intrusion prevention portion is provided opposite the opening side rail of the mounting frame, and the intrusion prevention portion is housed in the greenhouse when the window is closed.

  The intrusion prevention unit may be bent toward the insect net. According to this structure, an intrusion prevention part can be smoothly accommodated in a greenhouse.

  In addition, the intrusion prevention unit may be rotatably mounted on the opening side flange, and a guide member that guides the intrusion prevention unit to prevent separation from the opening side rail may be provided. According to this configuration, by rotating the intrusion preventing portion, the intrusion preventing portion can be adjusted to a position facing the opening side rail of the mounting frame, and therefore can be used regardless of the size of the window. Furthermore, since the guide member is provided, it is possible to prevent the intrusion prevention portion from rotating while the window is opened and closed, and to prevent the intrusion prevention portion from being shaken and separated from the opening side bar of the mounting frame.

  In addition, the guide member may be attached to the opening side rail of the attachment frame. According to this configuration, the guide member can be easily provided on the movement line of the intrusion prevention unit.

  The intrusion prevention unit and the guide member may be arranged on a straight line along the vertical direction when viewed from the opening side of the window. According to this configuration, since the intrusion prevention portion is smoothly guided by the guide member, a lateral force does not act on the intrusion prevention portion and is not easily damaged.

  Further, the intrusion prevention unit may be a linear member. According to this configuration, less material is required to form the intrusion prevention unit, and the cost can be reduced.

  According to the net intrusion prevention device of the present invention, when the window is closed, the insect net can be prevented from entering the indoor side, and even when the window is repeatedly opened and closed, it is not fatigued and can be hardly damaged.
