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 greenhouse.

(Prior Art) Cultivation houses such as vinyl greenhouses sometimes require ventilation in order to protect crops from the adverse effects of high temperature and high humidity, and are therefore provided with opening/closing window devices.

With such opening/closing window devices for houses, the structural strength of the house itself to which it is installed is weak, and the window frame is not reinforced by attachment to the house, so the window frame itself must have a certain degree of strength. If the window frame is not held, the window frame may deform and the window may not open and close smoothly, or the window may not open and close.Furthermore, the influence of the load due to wind pressure must be eliminated, so it is important to reduce the weight. Have difficulty.

On the other hand, on the house side, since the strength of the house itself is weak, it is not desirable to support a heavy opening/closing window device, and the lighter the opening/closing window device is, the better.

In addition, since such opening/closing window devices for greenhouses are often used on surfaces that are not vertical, such as the ceiling surface (roof surface) of the greenhouse, there is a problem of rainwater splashing onto crops unless rainwater measures are taken. Even if a sealing member such as a rubber gasket is used as in the opening/closing window device of a general house, flying sand and soil tend to adhere to the sealing member, making it difficult to effectively prevent rainwater from entering.

(Problems to be Solved by the Invention) As mentioned above, opening/closing window devices used in cultivation houses such as vinyl greenhouses require strength and must withstand wind pressure. There is also a problem with rainwater countermeasures.

The present invention was made in view of these points, and aims to reduce the weight of an opening/closing window device for a cultivation house without reducing its strength, or to increase its strength without increasing its weight, and to reduce rainwater. It also attempts to solve this problem.

) is provided as a protruding rail portion 36 on one side of the frame portion 35.

The front and rear (or upper and lower) pair of frame members 33 have a U-shaped folded edge 40 on one side of the face plate 39 from one side edge and the other side edge of the face plate 39, as shown in FIG. The rail part 42 with a C-shaped engagement groove 41 is integrally formed, and a pair of protrusions 43 are formed on the other side of the U-shaped folded edge 40. The opposing surfaces in the shaped engagement groove 41 are smooth arcuate surfaces 44, and the tips of the protrusions 43 are also smooth curved surfaces with no corners.

Further, as shown in FIG. 5, the pair of left and right frame members 34 are shaped like a cylindrical shape, and a pair of protrusions 49 are formed on the inner surfaces of the tips of both side portions 48 following the intermediate side portion 47. In addition, it has a cross-sectional shape in which a pair of protrusions 50 are formed on the side of the intermediate side part 47 on the outer surface of one side part 48, and the space between the protrusions 49 is a dovetail groove 51 with the opening side narrowed. The tip of the protrusion 50 has a smooth curved surface with no corners.

The four frame members 33 and 34 are each formed to a predetermined length, and each is subjected to predetermined processing such as perforation or partial cutting, and then combined into a predetermined shape and adjacent to each other. Between the frame members 33 and 34, the rail portion 42

A vinyl film 32 is stretched and held on the frame portion 35, thereby forming both fenestrations 6 and 7.

At this time, elastic soft tape 57 is pasted in advance as a cushion body over the folded edge 40 of the frame material 33 constituting the frame portion 35 and on the intermediate side portion 47 of the frame material 34. As a result, the soft tape 57 is interposed between the vinyl film 32 and the frame 35, which prevents the vinyl film 32 from rubbing against the frame 35 and tearing, and especially prevents the vinyl film 32 from flapping due to wind pressure. Even if the film 32 is damaged by the frame 35, there is no fear that the film 32 will be torn by the frame 35, and airtightness can be maintained.

In addition, in the above-mentioned left and right double fenestrations 6.7, the width of the face plate part 39 of the frame member 33 equipped with the rail part 42 of the movable frame 31 of the left double fenestration 6 and the movable frame of the right double fenestration 7 The width of the face plate part 39 of the frame member 33 provided with 31 rail parts 42 is changed.

By sequentially engaging the C-shaped engagement grooves 41 of the rail portion 42, the pair of left and right fenestration windows 6, 7 are supported by the window frame 5 so as to be linearly openable and closable in the left-right direction.

Here, in the left and right double openings 6.7, the respective protruding rail portions 36 and the rail portions 42 of the frame portion 35 are engaged with the rollers 61.62 of different rows, so that the left and right double openings are When closing the window 6.7, the protruding rail portions 36 of the left and right opening/closing windows 6.7 are prevented from colliding with each other.
Since the width of the face plate part 39 of the frame member 33 equipped with 2 is different, when the left and right double fenestrations 6°7 are supported on the window frame 5, the width of the frame part 35 of the left and right double fenestrations 6°7 is changed. The heights are equal, and when both the left and right fenestrations 6.7 are closed, the mutually opposing frame members 34 of the left and right fenestrations 6.7 abut at the same height.

Further, the outer diameter of the rollers 61.62 is made larger than the width of the opening of the C-shaped engagement groove 41 of the rail portion 36.42. Even if the rollers 61 and 62 are installed in the C-shaped engagement groove 41

The outer peripheral surfaces of the rollers 61 and 62 are also circular arc surfaces 65,
The radius of curvature of the arcuate surface 65 of the rollers 61 and 62 is the same as that of the rail portion 3.
6.42 is made smaller than the radius of curvature of the circular arc surface 44, thereby making the roller 61. 62 and rail part 36.4
2 is always a point contact, so the resistance is extremely small.

Next, the opening/closing mechanism of both fenestrations 6.7 will be explained.

As shown in FIG. 8, the opening/closing mechanism 70 uses a driving wire, and synthetic resin driven pulleys 71 and 72 are provided at the front and back (or up and down) positions on the left inside the opening part of the window frame 5. At the same time, a driving pulley 73 made of metal and a driven pulley 74 made of synthetic resin are supported pivotally at the front and back (or up and down) positions on the right side of the opening section of the window frame 5. By hooking and turning the wire 75 as a drive line to .72 and 74 and rotating the drive pulley 73, the wire 7

The driven pulley 72 and the driven pulley 71 are hung in this order, and the other end is attached to the coil spring 76 to connect them endlessly. When the drive pulley 73 is rotated counterclockwise, the wire 75 moves in the direction of the arrow. and the front and back inside the window frame 5 (
A part of the wire 75 moves to the left and right in parallel to the row direction of the rollers 6162 at each of the upper and lower positions.
The right side frame member 34 of the left side double fenestration 6 is connected to the two parts (or upper and lower), and the right side double fenestration is connected to the two parts before and after (or upper and lower) that move to the right side of this wire 75. The frame member 34 on the left side of 7 is connected.

Therefore, when the driving pulley 73 is rotated counterclockwise, both the left and right fenestrations 6 and 7 open synchronously, and the driving pulley 73
When rotated clockwise, both the left and right fenestrations 6, 7 close synchronously.

Here, a coil spring 76 is inserted between both ends of the wire 75.
, so the wire 75 does not slacken and the wire 7
5 is kept constant.

The wire 75 is connected to the frame member 34 of the double fenestration 6.7 by using a speed nut 78 to connect the wire 75 to the connecting fitting 77 attached to the frame member 34, as shown in FIG.
Since this is done by tightening the wire 75 and both fenestrations 6 and 7, it is extremely easy to set and adjust the positional relationship between the wire 75 and both fenestrations 6 and 7.

Further, as shown in FIG. 10, the drive pulley 73 has a spiral groove 79 on its outer periphery, and the wire 75 is wound around this groove 79, so that the drive pulley 73 and the wire 75 do not slip and are securely attached. The wire 75 can be driven to

This auxiliary arm 91 is also equipped with rollers 61.62 in the same way as the face plate portion 12 of the frame member 11, and the rail portions 42 of the double fenestration 6.7 are engaged with the rollers 61.62. Even when the window 6.7 is open, it is possible to fully support both fenestrations 6.7.

〔Effect of the invention〕

As described above, in the opening/closing window device for the cultivation house of the present invention, there is a rain gutter in the center of the opening 11 of the window frame, and this rain gutter connects the opposite parts of the window frame, so that the window frame is connected to the rain gutter. It is possible to reduce the strength of the window frame alone, so it is possible to reduce the weight of the window frame without reducing its strength, or increase the strength of the window frame without increasing its weight. Since the pair of fenestration windows are opened in a straight line, it is difficult for the fenestration windows in the open state to receive wind pressure, which makes it possible to reduce the weight of the fenestration windows.As a result, while increasing the strength, It is possible to reduce weight, and when installed on the roof surface of a house, rainwater may leak from the joints of both fenestrations even when both fenestrations are closed. The rainwater drained from the rainwater enters the rain gutters, so there is no need to worry about rainwater splashing on the crops.
