Description

  The present invention relates to a greenhouse curtain moving member and a greenhouse curtain opening / closing mechanism used to open and close a curtain disposed at a predetermined height in a greenhouse to partition an upper space in the greenhouse and obtain a heat retaining effect, a light shielding effect, etc. About.

  In Patent Documents 1 and 2, there is a greenhouse curtain opening / closing mechanism that adjusts the indoor temperature and the like by arranging a curtain for heat insulation and light shielding made of a plastic film or the like in an upper space in the greenhouse and opening and closing the curtain. It is disclosed. The curtain is usually fixed at the base edge, the leading pipe is connected to the opposite edge (tip edge), and the driving rope arranged along the curtain opening and closing direction is connected to the leading pipe, The curtain is opened and closed by moving the lead pipe by driving the drive rope. That is, when the curtain is closed, the curtain is pulled by the leading pipe and unfolded, and when the curtain is opened, the leading pipe is moved in the opposite direction, and the curtain is pushed together to open.

  When collecting curtains, a greenhouse curtain collecting member is attached to the leading pipe so that the curtains can be collected together smoothly. The greenhouse curtain moving member includes a moving tool provided so as to protrude upward or downward from the leading pipe depending on whether the curtain is positioned above or below the driving rope. By the tool, the curtains are gathered together so that a part of the curtain is not left behind in the moving direction of the leading pipe.

  As shown in FIGS. 1 to 3, for example, in Patent Document 3, in a greenhouse having a mountain-shaped roof as viewed from the end face side, the base end of one curtain is located near one side of the greenhouse. The edge is fixed, the leading edge is connected to the leading pipe, and the leading pipe moves between the side of the one side and the top of the greenhouse to open and close the one curtain, and similarly the other side of the greenhouse The base edge of the other curtain is fixed in the vicinity of the side surface, the leading edge is connected to the leading pipe, and the leading pipe moves between the vicinity of the other side surface and the vicinity of the top of the greenhouse as described above. There is also a thing that opens and closes. The curtain opening and closing mechanism disclosed in Patent Document 3 is a so-called two-sheet tension type in which the leading edge of each curtain closes toward the vicinity of the top of the greenhouse and opens in the opposite direction. Even in such a type, the leading pipe is attached with a curtain collecting member for a greenhouse provided with a collecting tool.

Japanese Patent Laid-Open No. 10-304780 JP 2002-238370 A JP 2008-29314 A

  As shown in Patent Document 3, a fixing tension formed by fixing a plastic film or the like in a fixed state is provided in the vicinity of the end point in the moving direction of the leading pipe when the curtain is closed. In the case of Patent Document 3, a fixing tension is provided at a predetermined height near the top of the greenhouse, and when the curtain is closed, the leading pipe moves to its lower position. As a result, the fixing tension and the curtain overlap, so that the sealing performance is enhanced in a planar positional relationship.

  However, if the fixing tension and the curtain are at a distance in the vertical direction, the sealing performance is impaired by the gap. Therefore, in the mode shown in FIG. 2 and FIG. 3 of Patent Document 3, the vicinity of the end edge of the fixed tension is hung downward to prevent a vertical gap. If the fixing tension and the curtain are brought too close to each other in the vertical direction, the gathering tool of the greenhouse curtain gathering member becomes an obstacle. Therefore, such a device is required for the fixing means for fixing.

  Moreover, although the shelf line for supporting the lower surface side of a curtain is stretched in a greenhouse, there is also a part which attaches a fixed tension on this shelf line. In this case, the fixing tension can be provided more simply than the fixing tension attaching means as shown in FIGS. 2 and 3 of Patent Document 3, and the vertical gap between the curtain and the fixing tension can be further reduced. However, when the fixing tension is arranged in this manner, when the curtain is closed, the pressing tool of the greenhouse curtain collecting member comes into contact with the fixing tension. Therefore, it is necessary to remove the pressing tool provided at the contact position. . When the clasp is removed, when the curtain is opened, the curtain corresponding to the position is not collected and a part of the curtain is left behind in the moving direction. As a result, when the curtain is opened, a shadow is generated by the left part, and the lighting performance is affected.

  Regarding these points, Patent Documents 1 and 2 do not have a detailed description of fixing tension, but have the same problem. Further, not only the fixing tension, but also when there is some member in contact with the gathering tool, there is a similar problem because the gathering tool cannot be provided.

  The present invention has been made in view of the above, and a gathering tool is attached even at a portion that comes into contact with another member, and the portion left behind when gathering can be reduced, and the daylighting performance when the curtain is opened is improved. It is possible to provide a greenhouse curtain moving member and a greenhouse curtain opening / closing mechanism having the greenhouse curtain moving member that can improve the sealing performance and heat retention when the curtain is closed, and can be attached with a fixed tension. Is an issue.

  In order to solve the above-described problems, a greenhouse curtain collecting member according to the present invention is a greenhouse curtain collecting member that is connected to a curtain disposed in a greenhouse and is attached to a leading pipe that opens and closes the curtain. When the lead pipe is moved in the direction of pulling the curtain when the lead pipe moves in the direction of pulling the curtain, the lead pipe tilts from the standing posture standing up with respect to the fitting portion and becomes a tilted posture. When the leading pipe moves in the direction of pushing the curtain, the guide pipe is supported so as to change from the tilted posture to the standing posture when separated from the other member.

  The gathering tool is a member of a predetermined length whose base is rotatably attached to the attachment part, and the attachment part is provided with a stopper for restricting a standing angle when the gathering tool is in a standing posture. Preferably it is. It is preferable that the abutment tool is attached to the attachment portion such that a tip portion located on the side opposite to the base portion is on the lower side when the stand is in a standing posture. The gathering tool is made of a metal linear member processed into a substantially U shape, each end portion thereof constitutes the base portion, and a portion bent in a substantially arc shape constitutes the distal end portion, At least one of the end portions may be configured to be loosely inserted into and supported by a through hole formed in the attachment portion. The attachment portion may have a drive rope engaging portion that engages the leading pipe with a drive rope.

  The greenhouse curtain opening and closing mechanism of the present invention includes a curtain that can be opened and closed in the greenhouse, a drive rope that is disposed along the opening and closing direction of the curtain, and is connected to the drive rope. A leading pipe provided at an end edge, a curtain attaching member for a greenhouse attached to the leading pipe and collecting the curtain when the leading pipe moves in a direction of pushing the curtain, and below the driving rope Between the shelf line for holding the curtain at a predetermined height, and between the drive rope and the shelf line, in the vicinity of the end point in the closing direction of the curtain. A fixing tension that at least partially overlaps the curtain when the curtain is closed, and as the curtain moving member for the greenhouse, in the closing direction of the curtain When the leading pipe moves and contacts the fixed tension, the posture changes from a standing posture to a tilted posture, and when the leading pipe moves in the opening direction and the contact with the fixed tension is released, the tilted posture is released. A device having a tool that changes its posture to a standing posture is used.

  The curtain holding member for a greenhouse according to the present invention turns into a tilting posture when the holding tool comes into contact with another member and turns into a tilting posture, and turns away from the other member in a standing direction when separated from the other members. It is the composition which becomes a standing posture. Therefore, when closing the curtain, if a fixing tension such as a plastic film is stretched near the end of the direction of movement of the lead pipe, the approaching tool tilts when it comes into contact with the fixing tension. It is possible to close the curtain pulled by the lead pipe to the extent that it overlaps the fixed tension. For this reason, the fixed tension can be arranged on the shelf line, the mounting structure of the fixed tension can be simplified, the vertical gap between the fixed tension and the curtain is reduced, and the airtightness and heat retention when the curtain is closed are improved. Can be increased.

  On the other hand, when the curtain is opened, if it moves to a range where the contact with the fixing tension disappears, the gathering tool becomes an upright posture, so that the curtain can be gathered smoothly. When the curtain is closed, it is tilted so that there is no interference with the fixing tension, so it can be attached to the necessary place in the lead pipe, and the part left behind when gathering the curtain than before Can be reduced and the daylighting when the curtain is open can be improved.

  Hereinafter, the present invention will be described in more detail based on embodiments shown in the drawings. FIGS. 1-5 is a figure for demonstrating the curtain close-up member 1 for greenhouses which concerns on one Embodiment of this invention.

  The greenhouse curtain gathering member 1 includes an attachment portion 10 and a gathering tool 20. The attachment part 10 is attached to the leading pipe 200 connected to the leading edge of the curtain 100 disposed in the greenhouse. The mounting portion 10 further includes an annular portion 11 and a drive rope engaging portion 12. The annular portion 11 has a diameter that can be attached around the leading pipe 200, and is attached so as to surround the outer periphery of the curtain 100 in a state where the leading edge of the curtain 100 is wound around the leading pipe 200. In the illustrated example, the drive rope engaging portion 12 is provided integrally with the annular portion 11 at a position protruding in a direction substantially orthogonal to the annular portion 11. The drive rope engaging portion 12 includes two sandwiching pieces 12a and 12a that are divided into two, and the drive rope 300 that is stretched in the opening and closing direction of the curtain 100 is sandwiched between the sandwiching pieces 12a and 12a. .

  The approaching tool 20 is provided so as to be able to take a standing posture that protrudes in either the upper or lower direction with respect to the attachment portion 10. In the present embodiment, the gathering tool 20 is formed by processing a metal linear member into a substantially U shape when viewed from the front, and has one end portion 20 a rotatably attached to the attachment portion 10. Specifically, in the drive rope engaging portion 12 of the attachment portion 10, a penetration that is penetrated in the thickness direction through the lower wall portion 12 b adjacent to the annular portion 11, below the portion that holds the drive rope 300. A hole 12c is provided, one end 20a of the gathering tool 20 is bent in the lateral direction, and is inserted through the through hole 12c. One end portion 20a is configured not to come out by penetrating the through hole 12c and then engaging the other end portion 20b by bending the other end portion 20b. The side tool 20 is provided so that the ends 20a and 20b are bent slightly forward (in a direction away from the annular part 11) in a side view, and the corners 20c are in contact with the outer surface of the annular part 11. Yes. That is, when trying to tilt the approaching tool 20 toward the annular portion 11, the vicinity of the corner portion 20 c comes into contact with the outer surface of the annular portion 11, and further tilting is restricted. That is, the outer surface of the annular portion 11 serves as a stopper that regulates the standing angle when the tilting portion 20 is tilted and raised in the direction of the annular portion 11. In the present embodiment, the attachment portion 10 (more precisely, the direction in which the drive rope 300 is held between the attachment portions 10) with the vicinity of the corner portion 20 c of the abutment tool 20 in contact with the outer surface of the annular portion 11. It is set so as to be at a position upright approximately 90 degrees with respect to the angle.

  Moreover, the outer diameter of the linear member which comprises the gathering tool 20 is smaller than the internal diameter of the through-hole 12c. Accordingly, one end 20a is loosely inserted into the through-hole 12c, and the abutment tool 20 has the one end 20a as a base (support shaft) and is closer to the mounting portion 10 in the front direction ( 1 (in the X direction in FIG. 1), while in the direction (Y direction in FIG. 1) that falls so as to approach the annular portion 11 as described above, the angle abuts on the outer surface (stopper) of the annular portion 11 It is set at a rotation angle that only tilts. In the present embodiment, since one end (base) 20a that functions as a support shaft is loosely inserted into the through hole 12c, when the abutment tool 20 is disposed below the mounting portion 10, In the case where there is no restriction, the clasp 20 becomes a standing posture due to free fall. Therefore, in this embodiment, the attachment tool 20 is attached to the leading pipe 200 and the drive rope 300 so as to be positioned below the attachment portion 10.

Next, the operation of the greenhouse curtain collecting member 1 according to this embodiment will be described.
For example, as shown in FIG. 3, the greenhouse curtain opening / closing mechanism has a shelf line 400 extending in a mountain shape around the top in the width direction in the greenhouse, and the shelf line 400 is placed on the side of the greenhouse. A pair of left and right curtains 100 that are stretched so as to move from the head side to the top side and open and close the upper space of the greenhouse, a leading pipe 200 that is attached to the leading edge of each curtain 100, and the opening and closing direction of each curtain 100 It has a driving rope 300 stretched along the shelf line 400, and further has a fixed tension 500 made of a plastic film stretched and fixed near one end of the shelf line 400. The driving rope 300 is disposed above the shelf line 400.

  As shown in FIG. 1, the leading edge of the curtain 100 is wound around the leading pipe 200, and the annular portion 11 of the mounting portion 10 in the greenhouse curtain moving member 1 of this embodiment is attached from the outside. ing. A drive rope 300 is sandwiched between the drive rope engaging portions 12 of the greenhouse curtain moving member 1. At this time, the front end 20d which is a substantially U-shaped arc portion of the gathering tool 20 is on the lower side, that is, on the same side with respect to the position of the fixing tension 500 on the shelf line 400 and the drive rope 300. (See FIG. 4). Moreover, it attaches so that the inclination direction of the gathering tool 20 may turn to the direction which rotates backward (X direction of FIG. 1) with respect to the moving direction at the time of moving to the direction which closes the curtain 100, and tilts.

  When the leading pipe 200 is located closest to the side of the greenhouse and the curtain 100 is closed from the fully open state, the driving rope 300 is driven to move the leading pipe 200 along the shelf 400 to the top of the greenhouse. Move it in the direction. As the lead pipe 200 moves, the curtain 100 is pulled and deployed. At this time, the gathering tool 20 of the greenhouse curtain gathering member 1 is in a state of hanging downward with respect to the mounting portion 10 due to free fall. Since the leading pipe 200 is connected to the driving rope 300, it passes above the shelf line 400, but a portion of the curtain 100 behind the leading edge connected to the leading pipe 200 is gravity. Is developed while contacting the shelf line 400.

  When the leading pipe 200 moves further and reaches the vicinity of the end point of the closing operation of the curtain 100, the leading pipe 200 is connected to the driving rope 300 above the shelf line 400, so that the leading pipe 200 passes over the edge of the fixed film 500. Although it tries to pass, since the gathering tool 200 is in a state of hanging downward, the gathering tool 200 contacts the edge of the fixed film 500. However, in this embodiment, since the pushing tool 200 is configured to tilt backward in the traveling direction with respect to the mounting portion 10, when the contacting tool 200 comes into contact with the edge of the fixed film 500, the pushing tool 200 advances as shown in FIG. Tilt backward in the direction. When the leading pipe 200 further moves above the fixed film 500 in the closing direction, the approaching tool 200 further tilts, and moves together with the leading pipe 200 in the gap between the curtain 100 and the fixed film 500. The portion of the curtain 100 that is located behind the leading pipe 200 in the traveling direction is developed so as to be in contact with the shelf line 400 as described above, so that the leading pipe 200 moves in the closing direction above the fixed film 500. As a result, the portion of the curtain 100 located behind the leading pipe 200 comes into contact with the fixed film 500. Therefore, when the curtain 100 is closed, there is almost no vertical gap in a range where the fixed film 500 and the curtain 100 are overlapped in a plan view, and the airtightness and heat retention at the time of closing are high.

  When the curtain 100 is opened from the closed state, the drive rope 300 is driven so as to travel in the opposite direction. Thereby, the lead pipe 200 moves toward the side part of a greenhouse. At the end point when the curtain 100 is closed, as described above, the urging tool 20 of the greenhouse curtain urging member 1 has a tilted posture (the posture shown in FIG. 5) with the tip portion 20 d side contacting the surface of the fixed film 500. It has become. However, as the leading pipe 200 moves toward the side of the greenhouse, the range in which the fixed film 500 is in contact with the abutting tool 20 gradually decreases, and the abutting tool 20 has a tip portion with the end 20a as a fulcrum. Is rotated so as to be positioned substantially vertically downward to assume a standing posture (the posture shown in FIG. 4).

  As the leading pipe 200 moves toward the side of the greenhouse, the curtain 100 gradually gathers from the leading edge side connected to the leading pipe 200, and as the gathered portion increases, the leading pipe 200 increases. The vehicle is overtaken and left behind behind the movement of the lead pipe 200. At this time, in the greenhouse curtain gathering member 1 of the present embodiment, when the restriction by the fixed film 500 is eliminated, the gathering tool 20 is in the standing posture (the posture shown in FIG. 4). Since the gathering tool 20 in the standing posture protrudes downward larger than the diameter of the leading pipe 200, it gathers together while pushing the curtain 100 from the front edge side. Conventionally, when the fixed film 500 is fixed to the shelf line 400 and the fixed film 500 is positioned below the drive rope 300, the one that protrudes downward as the closing tool 20 of the curtain moving member 1 is the closing operation. In this case, the approaching tool 20 comes into contact with and interferes with the fixed film 500, so that it cannot be attached to the position where the fixed film 500 is stretched. Therefore, in some cases, the curtain 100 cannot be gathered in that portion. However, according to the present embodiment, the gathering tool 20 that protrudes downward can be provided even at a position where it interferes with the fixed film 500. In addition to improving the airtightness and heat-retaining properties when the 100 is closed, the curtain 100 can be gathered without being left behind when opened.

  When the curtain 100 reaches the vicinity of the end point at the time of opening, that is, the vicinity of the side of the greenhouse, in the present embodiment, the gathering tool 20 is provided at a necessary position along the longitudinal direction of the leading pipe 200. Can be opened without leaving behind, the area where the shadow is generated when fully opened can be reduced, and the lighting performance can be improved.

 In the above embodiment, a metal linear member is used as the gathering tool 20, but it may be made of synthetic resin, and is not limited to a linear one, but a base of a rod-like one is attached to the attachment portion 10. You may make it support so that rotation is possible. Moreover, although the gathering tool 20 is set as the structure which takes the standing posture by rotating below with respect to the attachment part 10, it can also be provided so that the gathering tool 20 may stand up using a spring member etc. . In this case, when the abutment tool 20 comes into contact with the fixed tension or the like, the abutment tool 20 tilts against the elasticity of the spring, and when the contact with the fixed tension or the like is released, the spring changes to a standing posture due to the elasticity of the spring. The same operations and effects as described above can be obtained.

  Moreover, since the curtain pulling member 1 for greenhouses of the said embodiment has provided the drive rope engaging part 12 in the attaching part 10, it is engaged and arrange | positioned at the drive rope 300, but the adjacent drive rope 300, It is also possible to provide the above-mentioned greenhouse curtain collecting member at a portion on the leading pipe 200 that is positioned while 300 is stretched. Furthermore, in the said embodiment, although fixed tension is mentioned as an example of the other member which the closer 20 contacts, not only this but the other curtain member in the structure where two curtain members contact directly, and other By arranging the curtain collecting member for a greenhouse according to the present invention at a position where it has been impossible to arrange the collecting tool due to interference with the conventional collecting device, the same operation and effect as described above can be obtained. It is done.

  In the above embodiment, the case where the roof portion is applied to a mountain-shaped greenhouse when viewed from the end face side is described. However, the roof portion can be applied to a greenhouse with a substantially horizontal flat roof. The present invention is not limited to the case where the is stretched in a mountain shape toward the approaching direction, but can also be applied to those that are stretched horizontally.
