Abstract

(57) [Summary] (with amendments) [Purpose] In a greenhouse in which a window is opened on the side and the window can be opened and closed by a door that can be opened and closed, the substantial opening area of the window is increased and , eliminating the risk of damage from wind pressure. [Configuration] A door 4 that opens and closes a window 3 opened on the side of the greenhouse.
Both ends of a rotating shaft 5 crossing the center of the window were supported on both sides of the central portion of the window, and the window was attached to be rotatable about the rotating shaft. As a result, the effective opening area of the window is expanded, and the protrusion of the window to the outside of the greenhouse is reduced by about half, so resistance due to external wind pressure is also reduced, eliminating the risk of damage.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to an improved structure of side windows in greenhouses, which significantly improves ventilation efficiency. The purpose is to improve functionality.

0002

[Conventional technology]

The conventional structure of side windows in greenhouses is to install a suitable hinge at one end of the window opening. one end of the opening/closing door is rotatably supported, and the other end is supported outwardly by a cylinder. The most common structure is one that can be pushed open by a driving means such as a mechanism.

0003

[Problem that the idea aims to solve]

However, with the side window of the conventional structure mentioned above, the door can only be held at one end. Therefore, from the perspective of maintaining its strength, it is necessary to use high-strength materials. At the same time, it is necessary to use a relatively thick glass plate, which increases the weight. These problems include the fact that they are bulky and costly, and are easily damaged by wind pressure. There are some difficulties. Also, due to the structure of the side windows mentioned above, the opening angle of the door is limited to 45 degrees at most. As a result, the actual opening area of the side windows is relatively small, and the ventilation efficiency is therefore not very good. It wasn't good.

0004

[Means to solve the problem]

Therefore, the present invention solves the above-mentioned difficulties of the conventional technology and has a structurally reasonable structure. At the same time, it has a functionally superior structure, and in particular, we aim to significantly improve ventilation efficiency. It is designed to reduce costs, and specifically, it is designed to reduce costs. In the case where a window is opened and the window can be opened and closed by a door that can be opened and closed, The door has both ends of a rotating shaft that crosses the center supported on both sides of the center of the window. The present invention relates to a structure of a side window in a greenhouse, which is installed rotatably around the rotation axis.

[0005]

[Effect]

In the above configuration, centering on the rotation axis that crosses approximately the center, The door can be rotated while supported on the support point to open the side window, and vice versa. You can close the side window by rotating it in the opposite direction.

[0006]

【Example】

The specific contents of the present invention will be explained below based on the illustrated embodiments. Pillars, 2 are palms for forming the roof, 3 are side windows installed on the side of the greenhouse, 4 indicates a door.

[0007] The door 4 includes a frame 4a, aggregates 4b arranged at regular intervals with respect to the frame, and the aggregates 4. It consists of transparent glass placed between A rotating shaft 5 is integrally attached to the door 4 at a position crossing approximately the center thereof, Moreover, both ends of the rotary shaft 5 are mounted on both sides of the center of the side window 3 by rotary shaft supports 9. By supporting it rotatably and rotating it in a fixed direction around the rotating shaft 5, Now you can open the side windows or close them by rotating them in the opposite direction. There is.

[0008] In addition, in the above embodiment, the rotating shaft 5 is connected so as to cross approximately the center of the door 4. However, it is not necessarily limited to the structure described above. In addition to this, for example, the rotating shaft 5 may be placed only at both ends of the door 4. It is attached at a position along the axis that crosses the approximate center of the door 4, and is attached to the side window 3. It may be configured to be rotatably supported on both sides of the central portion.

[0009] Further, although the door 4 may be opened and closed manually, it is preferable that the door 4 be opened and closed manually. It is even better to use electric drive means via a mug gear or the like.

0010 FIG. 2 and FIG. 3 show a hydraulic cylinder as an example of the means for opening and closing the door 4. A state in which a driving means using a drive means is incorporated is shown. That is, in this case, the rod 7 of the hydraulic cylinder 7 fixed to the specific support 1 a, and a pin 7b is attached to the tip of the plate 6 whose base end is integrally fixed to the rotating shaft 5. By connecting the rod 7a of the cylinder 7 rotatably through the cylinder 7 and contracting the rod 7a of the cylinder 7, by opening the side window 3 (see Figure 2) or by distracting the rod 7a. The side window 13 can be closed (see FIG. 3).

[0011] In the figure, 8 represents a limit switch, and the door 4 can be rotated to open the side. When the window is opened, a part of the door 4 reaches its limit when the rotation limit of the door 4 is reached. contact lever 8a of switch 8 to stop further operation of cylinder 7. Ru.

0012

[Effect of the idea]

As mentioned above, the present invention consists of opening a window on the side of the greenhouse and using a door that can be opened and closed. The above-mentioned door has a rotating shaft that crosses the center of the door. Both ends are supported on both sides of the central part of the window and are rotatably installed around the rotation axis. Therefore, the stability of the holding part of the door is good, and there are few parts that protrude to the outside. The wind pressure resistance is low from the rollers, and as a result, high-strength profiles and thick There is no need to use hand glass, which reduces costs, and especially for side windows. The opening area can be significantly expanded and ventilation efficiency can be improved.
