Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to an opening / closing window device in a cultivation house such as a vinyl house.

(Prior Art) In greenhouses such as vinyl greenhouses, ventilation windows may be required in order to protect crops from the adverse effects of high temperatures and high humidity, so opening and closing window devices are provided.

In such an opening / closing window device for a house, the structural strength of the house itself to be mounted is weak, and the window frame is not reinforced by the mounting to the house, so that the window frame itself has a level of strength. Otherwise, the window frame will be deformed,
The window may not be opened and closed smoothly, or the window may not be opened and closed. Moreover, it is difficult to reduce the weight because the influence of the load due to the wind pressure must be eliminated.

On the other hand, on the house side, the strength of the house itself is weak,
It is not desirable to support a heavy window system, and the lighter the window system, the better.

Further, since such a window device for a house is often used on a non-vertical surface such as a ceiling surface (roof surface) of the house, there is a problem that rainwater is splashed on crops unless rainwater countermeasures are taken. However, even if a sealing member such as a rubber packing is used like an opening / closing window device of a general house, it is difficult to prevent rainwater from invading because the flying sand or soil easily adheres to the sealing member.

(Problems to be Solved by the Invention) As described above, an opening / closing window device used in a cultivation house such as a vinyl house requires strength and must endure wind pressure as well, but the weight reduction is contrary to this. Is required, and there is also a problem with measures against rainwater.

The present invention has been made in view of such a point, in the opening and closing window device in the cultivation house, to reduce the weight without reducing the strength, or to increase the strength without increasing the weight, rainwater, Is also trying to solve the problem of.

〔The invention's effect〕

As described above, in the opening and closing window device in the cultivation house of the present invention, there is a rain gutter at the center of the opening of the window frame, and since this rain gutter connects the facing parts of the window frame, the window frame is Since it is reinforced and the strength of the window frame alone can be lowered, it is possible to reduce the weight of the window frame without lowering the strength, or to increase the strength of the window frame without increasing the weight, Further, since the pair of both fenestrations are linearly diverging, the both fenestrations in the open state are less likely to receive wind pressure, which enables weight reduction of both fenestrations, resulting in increased strength and weight reduction. In addition, when installed on the ceiling surface (roof surface) of a house, rainwater may leak from the joint between both windows even when both windows are closed. Since it enters the rain gutter, there is no risk of rainwater splashing on the crops.
