JP 2002-181360 A

By the way, the crossflow type windmill is configured such that a long and narrow plate is arranged between upper and lower discs at intervals in the circumferential direction, and rotates with the central portion of the disc as a vertical axis (Patent Document 2).
JP 2003-139041 A

  When a crossflow type windmill is mounted on the ventilator main body, in order to release the hot air upward when the valve body of the ventilator main body is opened, ventilate the center of the lower disk of the crossflow type windmill. Use with a mouth.

  As is well known, a greenhouse usually has a roof that is curved in an arc or is slanted. In the case of a slanted roof, it is common that a diagonal beam is stopped at an interval in the longitudinal direction of the top horizontal beam, and a supporting horizontal beam is slightly below the top horizontal beam. Is installed between the diagonal beams, and the above-described ventilation device is fixed to the horizontal beams by using an attachment that surrounds the outside. As a conventional attachment 90, as shown in FIG. 6, a structure in which a locking portion 93 that is fastened to a horizontal rail 92 is protruded at the same height position on the left and right outer sides of a frame 91. In addition, this applicant does not know the location of prior art document information on which the attachment is posted.

  However, when the ventilation device 94 is fixed between the crosspieces 92 using the attachment attachment 90 as shown in FIG. 6, the ventilation device 94 is attached in a state inclined with respect to the vertical, and various problems are caused. Occurs. For example, in the case of rain, water enters the inside through the vent of the cross-flow type windmill, resulting in a state in which rain leaks from the ventilator. Also, the vinyl covering the ceiling has a round hole to insert the ventilation device, and the ventilation hole is attached by expanding the round hole, so if snow accumulates on the vinyl around the ventilation device, the weight will damage the vinyl Sometimes. Furthermore, since the ventilator is tilted, in the case of strong wind, the wind blows toward the valve body on the lower side of the ventilator, and the entire ventilator swings, and the swing may damage the vinyl. The above-mentioned problems are not limited to the case where the roof is inclined or attached to the top of the roof, but the case where the roof is curved in an arc shape, or a supporting side rail is provided below the top of the roof. The same occurs when installing two cables.

  The present invention was created in consideration of the above situation, and the problem to be solved is that a vertical state can be maintained even if a ventilator is attached between cross beams of different heights, thereby eliminating various problems. Is to do so.

  The invention of claim 1 is a tubular device with a top plate as a whole, and a ventilation device having a vent around the upper part thereof, between horizontal horizontal beams having different heights among roof frames of a greenhouse, In a mounting attachment for fastening, a frame surrounding the outside of the ventilation device is provided so as to be detachable from the ventilation device. It is characterized by protruding.

  The frame may be formed in a general cylindrical shape with the top surface flush, but in that case, the lower locking portion side of the upper surface is from the vinyl roof of the greenhouse, only for the roof slope Protruding form, damage to vinyl is great. In order to prevent this, it is desirable that the upper surface of the frame body is formed to be inclined obliquely downward from the higher locking portion side toward the lower locking portion side as in the invention of claim 2. .

  When the locking portions are provided with different heights on the left and right sides of the frame body, the single attachment attachment can only handle a specific inclination angle of the roof. In order to cope with various slopes of the roof, the attachment is composed of a plurality of parts as in the invention of claim 3. In other words, an upper frame and a lower frame that surround the different positions on the outside of the ventilation device are detachably attached to the ventilation device, and a locking portion that is fastened to a horizontal rail on one side of the left and right is outside the upper frame. The locking portion that protrudes from the left and right sides and fastens to the opposite horizontal rail protrudes outside the lower frame.

  In the case of dividing into an upper frame and a lower frame, it is possible to cope with various slopes of the roof by adjusting the distance between the upper frame and the lower frame. Therefore, it is desirable that the height of the upper frame is small. Further, if the ventilation device is cylindrical, the inner peripheral side of the upper frame is formed in a circular shape in plan view, and the outer peripheral side is formed in a rectangular shape in plan view, and a plurality of locking portions are provided to provide a horizontal beam at a plurality of locations. This is desirable for stability. In this case, on the upper surface of the upper frame, the side opposite to the locking portion protrudes from the vinyl roof of the greenhouse by the amount corresponding to the roof gradient, and the vinyl is greatly damaged. In order to prevent this, as in the invention of claim 4, while forming the frame body of the upper frame in a circular shape in plan view on the inner peripheral side, only one side of the left and right of the outer peripheral side is formed in a rectangle, It is desirable to provide a plurality of locking portions on the outer periphery of the rectangle.

  Since the attachment attachment of the invention of claim 1 protrudes the locking portion to be secured to the horizontal rail with different heights on the left and right sides of the frame body, the ventilation device is connected to the horizontal rail using this attachment attachment. If it keeps in between, the difference in height between horizontal crosspieces will be absorbed and a ventilation device can be supported in the state where it stood vertically. Therefore, rainwater is much less likely to fall to the vents around the top of the ventilator than before, preventing rain leaks, and other problems when the ventilator is fixed in an inclined state with respect to the vertical. Can be resolved.

  In the invention of claim 2, since the upper surface of the frame is formed to be inclined obliquely downward from the higher locking portion side toward the lower locking portion side, the vinyl roof of the greenhouse depending on the inclination. The upper surface of the frame body can be arranged below the lower side, and as a result, damage to the vinyl roof can be prevented as much as possible.

  The same effect as that of the invention of claim 1 can also be obtained when an attachment including the upper frame and the lower frame of the invention of claim 3 is used. When attaching the upper and lower frames to the ventilator, adjusting the distance between the upper and lower frames will allow the ventilator to be applied to roofs with different inclinations (those with different heights between the horizontal beams). Can be installed vertically.

  According to the invention of claim 4, since only one of the left and right sides of the outer periphery of the upper frame is formed in a rectangular shape in plan view and provided with a plurality of locking portions and fastened to the horizontal beam at a plurality of locations, the fixing to the horizontal beam is ensured. In addition, since the inner peripheral side of the frame body of the upper frame is formed in a circular shape in plan view, a semicircular portion on the opposite side to the locking portion of the upper frame protrudes from the vinyl roof of the greenhouse. However, the semicircular shape can prevent damage to the vinyl roof as much as possible.

  As shown in FIGS. 1 to 3, the ventilator 1 has a cylindrical shape with a top plate 9 as a whole, and a ventilator main body 4 that automatically opens and closes an opening 3 that allows the air in the greenhouse 2 to enter and exit from the top and bottom. And an adjustment cylinder 5 that is fitted into the upper part of the ventilation device main body 4 to adjust the height, and a crossflow type windmill 6 that is fitted into the upper part of the adjustment cylinder 5 to allow the inside and outside air to enter and exit.

  In order to fit the crossflow type windmill 6 into the upper part of the adjustment cylinder 5 and mount it, the lower part of the installation cylinder 7 having a circular shape in plan view is formed with a large diameter on both the inner periphery and the outer periphery, and the center of the installation cylinder 7 is formed. The windmill body 8 is supported upward. In the windmill body 8, a strip-shaped swash plate 10 is suspended around a disk-shaped top plate 9 with a space in the circumferential direction, and a vent hole 11 is provided between adjacent swash plates 10. Further, the central tube 12 is suspended from the center of the top plate 9, the central shaft 13 is accommodated in the central tube 12 via a bearing (not shown), and the lower end of the central shaft 13 is suspended below the central tube 12. A plurality of legs 14 hangs radially and obliquely at the lower end of the central shaft 13, and the lower end of each leg 14 is continuous with the upper inner periphery of the installation cylinder 7 as an integrated product.

  The adjustment cylinder 5 is formed such that the lower part has a large diameter at both the inner periphery and the outer periphery, the upper end is fitted into the lower end of the installation cylinder 7 that is wide, and the lower end is connected to the upper end of the ventilator body 4. It is placed and screwed from the outside so that hot air can escape.

  The ventilator main body 4 has a cylindrical body 15 with a lower portion formed on both the inner and outer circumferences having a large diameter in steps, and a disc-like valve body 16 in the body 15 that protrudes laterally from both eccentric sides. The shaft 17 is rotatably supported, and a force in a closing direction is applied to the valve body 16 due to a weight difference between both sides with the support shaft 17 as a boundary. Further, inside the body 15, a semicircular arc-shaped inner flange 18 that seals the inside of the body 15 up and down when the valve body 16 is in a horizontal state is provided in steps on both sides of the support shaft 17. The inside of the portion with the two inner flanges 18 that are circular in plan view is the opening 3. Then, the support shaft 17 protrudes outward from the body 15, one end of the string 19 is fixed to the support shaft 17, and the other end of the string 19 is fixed to the lower portion of the body 15. It is fastened.

  The valve body automatic opening / closing unit 20 accommodates a box-shaped slider 22 whose front surface is opened in a bottomed cylindrical guide 21, and penetrates the bottom of the guide 21 up and down to screw a screw rod 23, A slider 22 is fixed to the upper end of the screw rod 23. Accordingly, when the knob 24 at the lower end portion of the screw rod 23 is turned, the slider 22 moves up and down. An upper tension spring 27 and a lower tension spring 28 are respectively fixed to the upper piece 25 and the lower piece 26 of the box-shaped slider 22, and the lower end portion of the upper tension spring 27 is disposed outside the upper and lower portions of the elastic joining block 29. The upper tension springs 28 and the lower tension springs 28 are pushed in and integrated, and the upper tension spring 27 and the lower tension spring 28 are applied with a contracting force (lightly stretched state). The top piece 25 is fastened through a hole. And when the inside of the greenhouse 2 is lower than a set temperature, for example, 40 ° C., the valve body 16 of the ventilator main body 4 is maintained in a closed state, and when it becomes 40 ° C. or higher, the valve body 16 is automatically opened. A shape memory alloy that returns to its original shape at 40 ° C. is used for the lower tension spring 28. When the temperature becomes 40 ° C., the shape memory function works naturally, the lower tension spring 28 tries to shrink to the original shape, the joining block 29 is pulled downward, and accordingly the string 19 is pulled downward, The valve body 16 that has been closed is opened. Thereafter, when the temperature becomes lower than the set temperature, the shape memory function is canceled, the lower tension spring 28 is extended, the joining block 29 is raised, and the valve body 16 is naturally closed by its own weight utilizing the eccentricity.

  The greenhouse 2 is constructed by joining pipes to construct a framework, and the roof is constructed by joining the oblique beam 30 and the horizontal beam 31, and the supporting beam 32 is provided below the beam 31 at the top of the roof. It is erected between the inclined bars 30. The supporting horizontal beam 32 is thinner than the horizontal beam 31 at the top of the roof. Further, a round hole (not shown) having a smaller diameter than that of the ventilator 1 is opened only at a place where the vinyl 33 is covered on the roof and the ventilator 1 is attached.

  As shown in FIG. 1 or FIG. 2, the first example of the mounting attachment 34 of the present invention forms the inner peripheral side of the frame body 35 in a circular shape in plan view surrounding the adjustment cylinder 5 from the outside with almost no gap. The outer peripheral side of the body 35 is formed in a rectangular shape. On the left and right sides of the outer periphery of the frame 35, C-shaped locking portions 36 and 37 that open outwardly are provided at intervals in the front-rear direction, and one of the left and right locking portions 36 is located above the frame 35. The opposite locking portion 37 is provided on the lower side of the frame body 35. In the figure, the left locking portion 36 is formed with a large diameter for adding a thick horizontal beam 31 at the roof top, and the right locking portion 37 is formed with a small diameter for adding a supporting horizontal beam 32. .

  Further, in order to prevent the upper surface of the frame 35 from protruding above the vinyl 33, the left and right upper surfaces of the frame body 35 are directed from the higher locking portion 36 side to the lower locking portion 37 side. (See FIG. 1).

  Further, the frame body 35 is formed with a screw hole 38 at the thinnest portion thereof, and a screw (not shown) is screwed in from the outside and the tip of the screw is pressed against the adjustment cylinder 5, thereby attaching the attachment attachment 34 to the ventilation device 1. Secure to. Since the ventilator 1 itself is lightweight, the bonding strength between the ventilator 1 and the attachment attachment 34 is ensured only by pressing the screw, and the ventilator 1 does not fall out of the attachment attachment 34. Since the attachment 34 is made of synthetic resin, a female screw is naturally formed in the screw hole 38 when the screw is screwed.

  A second example of the attachment 34 is constructed from two members, an upper frame 39 and a lower frame 40 as shown in FIG. 4, and a locking portion that holds a thick horizontal rail 31 at the roof top on the left side of the rectangular upper frame 39. 36 is provided at an interval in the front-rear direction, and a locking portion 37 for holding a thin supporting horizontal bar 32 is provided on the right side of the lower frame 40 at an interval in the front-rear direction so that the upper frame 39 and the lower frame 40 are spaced apart in the vertical direction. And is fixed to the ventilation device 1.

  The upper frame 39 has a form in which the opposite side of the upper and lower sides of the upper surface of the upper frame 39 protrudes from the vinyl 33. Even in a form in which the frame 35 partially protrudes on the vinyl 33, in order to reduce damage to the vinyl 33, the inner peripheral side of the frame 35 of the upper frame 39 is formed in a circular shape in plan view as shown in FIG. In addition, the outer peripheral side is formed in a rectangular shape in the same way as in the first example only in the direction (left in the figure) in which the locking portion 36 is provided on the left and right. In this way, a plurality of locking portions 36 can be provided, whereby the locking to the horizontal rail 31 can be stabilized, while the vinyl 33 is attached to the frame 35 in the direction opposite to the locking portions 36. The right side can be enclosed in a semicircle.
