Description

[Detailed Description of the Invention] The present invention relates to an opening/closing device for ventilation windows in pellet houses.

As is well known, a pellet house has a roof, side walls, etc. made of transparent double walls, inside and outside.During the day, sunlight is introduced into the house and heat is absorbed, and at night, heat insulation such as foamed polystyrene particles is used between the double walls. This greenhouse structure is filled with pellets to form a heat insulating protective layer to prevent heat radiation from the greenhouse, and the pellets between the double walls are collected again the next morning.

Generally, ventilation inside a greenhouse is carried out by ventilation fans and ventilation windows, but when installing ventilation windows in pellet greenhouses, the outside window installed in the window frame of the outside wall and the window frame of the inside wall are used. There was no suitable structure because the structure needed to allow pellets to be filled between the inner window and the inner window to be installed. In particular, skylights are necessary to ventilate the upper part of the house, but conventional skylights include an outer window 16 corresponding to the outer wall 11 and an inner window 15 corresponding to the inner wall 12, as shown in FIG. There is only one that is fixed with a fixing member 17 and a hinge part 14 is provided at the base end of the outer window 16 so that the whole can be opened and closed in a hatch type.

However, in the case of such a hatch-type opening/closing window 13, since the inner and outer windows 15 and 16 are of a fixed type, a gap is created between the inner and outer walls 11 and 22, and airtightness is not maintained, and of course, pellets are There is a risk of the windows falling down, and in addition, it is often difficult to install all the windows that are to be installed in large numbers side by side so that the above-mentioned gaps do not occur, and deformation occurs due to aging and external forces. Furthermore, when adopting an opening/closing mechanism that simultaneously opens and closes a large number of windows by uniaxial operation, it is difficult to maintain the above-mentioned airtightness.

The object of the present invention is to provide a window opening/closing device for a pellet house that eliminates the above-mentioned drawbacks of the conventional device, prevents pellets from falling, and provides high airtightness.

Embodiments of the present invention will be described below with reference to FIGS. 2 to 5.

1 is the outer wall of the transparent double wall, and 2 is the inner wall of the same, which are the same as in the conventional example. 3 is the outside window,
Reference numeral 4 denotes an inner window, which is attached to the outer wall 1 and the inner window 2 by separate hinge parts 5 and 6, respectively, so that it can be opened and closed. Reference numeral 7 denotes a length-adjustable link connecting the outer window 3 and the inner window 4, and in the embodiment, a turnbuckle type link is used, and is attached to the frames of the outer window 3 and the inner window 4, respectively. The link 7 is connected by pivoting the hook 7a of the link 7 to a pivot shaft 8 or the like. 9 is a window opening/closing device.

In addition, although the above is an example implemented in a skylight, it goes without saying that this can also be implemented in a side window.

As mentioned above, since the outer window 3 and the inner window 4 have independent hinge parts, there is no risk of creating a large gap at the hinge part, and both windows are connected by a link 7 whose length is adjustable. By adjusting this, the outer window 3 and the inner window 4
The distance between the windows 3 and 4 can be adjusted, and the close contact between the windows 3 and 4 and the side walls 1 and 2 when closed can be ensured. Therefore, it is particularly suitable as an opening/closing device for skylights that are difficult to maintain and operate.

In particular, as is clear from FIG. 3, the mounting position (horizontal position) 5a of the hinge portion 5 of the outer window 3 and the
When the windows 3 and 4 are opened, the windows 3 and 4 are crushed, and both windows are The distance l between the two windows can be made significantly smaller than the distance L between both windows when the windows are closed, and thereby the height h of the opening can be increased.

According to the window opening/closing device for a pellet house according to the present invention, the outer window installed in the window frame of the outer wall and the inner window installed in the window frame of the inner wall can be opened and closed with separate hinge parts. Therefore, there is no risk of creating a large gap at the hinge part, and since both windows are connected by a length-adjustable link, by adjusting this, both windows can be adjusted to correspond to the inner and outer walls. This makes it possible to ensure close contact between both windows and the inner and outer walls when closed. As a result, precision is not required in the design and construction of the windows, and because adjustments can be made depending on each window, costs can be significantly reduced, and even if gaps occur due to aging, etc., adjustments can be made individually.

Therefore, there is no risk of pellets falling from between the window and the window frame, and watertightness and airtightness can be ensured, making it ideal as a window opening/closing device for this type of double-walled pellet house.
