Description

The present invention relates to a greenhouse netting device for greenhouses.

Conventional greenhouses have ventilating windows that can be opened and closed at the top, side, wife, or valleys of the greenhouse for the purpose of adjusting the temperature in the room, taking in fresh outside air, or taking in rainwater. The ventilation window is provided with an insect net so that pests that inhibit the growth of the crops do not enter or the insects useful for the crops do not escape from the greenhouse.

As the prior art, registered utility model No. 3081599 discloses a skylight device that can be opened and closed by a skylight that is pivotally attached to one side edge of the window opening formed on the roof and operated by a skylight opening and closing mechanism. An insect net that surrounds the opening formed when the skylight is opened is installed between the window opening and the skylight, and a space is provided laterally along the middle of the front portion of the insect net. An insect repellent for skylights is disclosed in which an intermediate holding frame is movably supported by an opening / closing arm of a skylight opening / closing mechanism so that an intermediate portion of the insect repellent net does not always protrude from the trajectory of the skylight.
Registered Utility Model No. 3081599

In this prior art, as shown in FIG. 4, the skylight 101 is opened and closed by a skylight opening / closing mechanism that is operated electrically or manually. This skylight opening and closing mechanism opens and closes the skylight by retracting an opening and closing arm 103 having one end pivotally attached to the lower surface of the front edge of the skylight via a link mechanism (not shown). It is pivotally attached to the bracket attached to the attachment seat provided in the lower surface of the front edge part. The base end portion of the skylight forms a hinge with a building material 102 made of an aluminum mold attached to the top of the main body frame.

The holding means 105 is for supporting the middle part of the insect screen 104 to prevent the insect screen from always protruding greatly out of the trajectory of the skylight. The holding means 105 includes an intermediate holding frame 106 provided in the lateral direction along the middle of the front portion of the insect screen 104, and an intermediate portion of the insect screen that constantly supports the intermediate holding frame and protrudes outside the rotation trajectory of the skylight. The support member 107 prevents this. The intermediate holding frame cuts or bends the roof frame portion so that the intermediate holding frame 106 does not hit the roof frame 108 when the skylight is closed and lowered.

The support member 107 also serves as the opening / closing arm 103 of the skylight opening / closing mechanism, and the intermediate holding frame 106 is supported by the opening / closing arm 103 so as to be freely movable. By attaching the U-shaped bolt 109 to the intermediate holding frame with the floating member sandwiching the open / close arm of the skylight,
It is assumed that the intermediate holding frame is freely attached to the open / close arm.

Since the intermediate holding frame 106 of the prior art insect screen moves up and down beyond the main body frame 108 of the greenhouse, when the skylight 101 is closed and lowered by partially cutting or bending the intermediate holding frame 106, the intermediate holding frame 106 becomes the roof frame 108. It is necessary not to hit it.
And with this construction, it is necessary not only to attach the insect screen to the skylight frame and the opening frame with a so-called gather with a margin in the ridge direction, but also to take time to install the insect screen. The amount of net usage also increases, increasing costs.

In order to reduce the cost, the floating member is sandwiched between the open / close arm of the skylight, the U-bolt 109 is attached to the intermediate holding frame, the intermediate holding frame 106 is freely attached to the open / close arm, and the insect net is arranged in the ridge direction. When the intermediate holding frame 106 is attached to the skylight frame or the opening frame without providing a so-called gather, the movement of the intermediate holding frame 106 is restricted by the insect net located on the upper surface of the main body frame 108 of the greenhouse. Therefore, it is difficult to move downward, and eventually it is difficult to prevent the insect net 104 from sticking out of the rotation trajectory of the skylight 101.

In view of the above circumstances, the present invention aims to overcome the disadvantages of the prior art, and with an extremely simple configuration, it is ensured that the insect net is sandwiched between the ventilation window and the greenhouse opening.
