Description

  The present invention relates to a curtain opening / closing device for a horticultural facility.

  As a conventional curtain opening and closing device for a horticultural facility, there is one disclosed in Japanese Patent Application Laid-Open No. 2014-57567 (Patent Document 1). What is shown is that a curtain is provided along the roof on the inside of the house main body in which the roof connecting the pair of side walls facing each other and the upper ends of the pair of side walls extends in the depth direction. The curtain is configured to be supported by a support portion extending in the depth direction and to be opened and closed along the depth direction.

  Three or more support portions of the curtain are arranged side by side in the width direction, which is the opposing direction of the pair of side walls, and the height of the curtain increases as the distance from the side walls increases. In addition, the curtain has a rod-shaped core material that connects at least both ends in the opposing direction of the pair of side walls at each free end in the depth direction, and the core material moves in the depth direction along the support portion. Open and close by.

  With such a configuration, the one disclosed in Patent Document 1 is configured so that the curtain opens and closes in the depth direction along the support portion, and thus it is possible to suppress a decrease in the amount of solar radiation due to the curtain in the fully opened state.

  Further, since the curtain is supported by the support portion at a higher position in the center in the width direction of the house, the curtain is unlikely to disturb a user who works standing up in the house body. Furthermore, since the curtain can avoid interference with the fan provided in the central portion in the width direction of the end wall and in the vicinity of the upper end portion, it is possible to avoid obstructing the air flow generated by the fan.

  Also, since both ends of the rod-shaped core material provided at the free end of the curtain can be moved simultaneously, both ends of the free end of the curtain move simultaneously in the depth direction, and variation in the opening of the curtain in the width direction Can be suppressed.

  The center of the operation frame in the length direction may be substantially coincident with the peak of the mountain shape of the moving frame. According to such a configuration, the tilt of the moving frame can be prevented during the opening / closing operation by making the center of the operating frame coincide with the apex of the character of the moving frame so that the center of the operating frame can be pulled.

  Moreover, the location where the upper end of the suspension member is connected to the inclined frame may be configured to substantially coincide with the center in the length direction of the left and right inclined frames. According to such a configuration, the operation frame pulls the center of the left and right inclined frames, so that the inclination of the left and right inclined frames can be prevented during the opening / closing operation.

  In addition, a plurality of pulling means are provided at the end of the curtain in the depth direction, one end of each pulling means is connected to the end of the curtain in the depth direction, and the other end of each pulling means is at the connecting portion. The operation means may be connected to the connecting portion. According to this configuration, the curtain can be connected to one end of the traction means at each of a plurality of locations, and the other end side of the traction means can be collectively operated by one operation means, so that the opening / closing operation can be stably performed.

  Further, the support means is at least three rails and a plurality of runners that run in the rails, and the three rails are arranged at a central rail disposed at an upper center portion, and at left and right positions below the central rail. It is comprised from the two end rails arrange | positioned by this, The height of the said connection part may be made to be higher than the installation height of the said end rail. According to such a configuration, each traction means is connected without slack by setting the height of the connecting portion to be higher than the installation height of the rail. For this reason, since the force which operates an operation means is reliably transmitted to each traction means, the connection part of each traction means and a curtain can be pulled all at once.

  As shown in FIGS. 1 and 2, a plurality of moving frames 110 are provided along the depth direction of the horticultural facility 10, and the curtain 130 is connected between the moving frames 110. In the present embodiment, a plurality of moving frames 110 are provided. However, one moving frame 110 may be provided. The curtain 130 may be configured to be connected to one or two or more moving frames 110.

  Hereinafter, each component of the curtain opening / closing device 100 of the present embodiment will be described with reference to FIGS.

(Moving frame 110)
As shown in FIG. 3, the moving frame 110 is mainly composed of left and right inclined frames 111 configured in a mountain shape (substantially U-shaped). The left and right inclined frames 111 include a mountain-shaped base frame 112 and auxiliary frames 114 that are coupled to both ends of the base frame 112 so as to be relatively movable.

  As shown in FIG. 3, the base frame 112 mainly includes two base frame constituent members 112a-1 and 112a-2 configured in the same shape. The base end portions 112b-1 and 112b-2 of the base frame constituent members 112a-1 and 112a-2 are connected to each other by a connecting member 112c so as to be relatively rotatable. Therefore, the angle of the angle of the base frame 112 is freely changed by changing the angle formed by the two base frame constituent members 112a-1 and 112a-2. In the present embodiment, the base frame 112 is configured such that the angle of the mountain shape is freely changed, but the present invention is not limited to this example, and the angle may be fixed.

  As shown in FIG. 3, the auxiliary frame 114 is coupled to both ends of the base frame 112 so as to be relatively movable. With such a configuration, the length of the left and right inclined frames 111 is changed by changing the protruding length of the auxiliary frame 114 from the base frame 112. A connecting portion 115 for connecting a chain 202 of the operation means 200 described later is provided below the auxiliary frame 114, and the connecting portion 115 is movable along the auxiliary frame 114. In the present embodiment, the length of the left and right inclined frames 111 is changed, but the length of the left and right inclined frames 111 may be fixed. Further, the connecting portion 115 may be fixed to the auxiliary frame 114.

  A curtain 130 is connected to the moving frame 110 at a lower portion of the base frame 112 and a lower portion of the auxiliary frame 114. Further, a locking member 116 that is swingably locked to a hook 126 of a support means 120 described later is provided on the top of the peak of the mountain shape of the base frame 112 and the top of each auxiliary frame 114.

(Supporting means 120)
As shown in FIGS. 3 to 5, the support means 120 is fixed to the purlin frame 14 provided at three locations of the horticultural facility 10 one by one. The support means 120 includes a long rail 122 disposed in the depth direction of the horticultural facility 10, a runner 124 that travels on the rail 122, a hook 126 suspended from the runner 124, a rail 122, and a purlin frame. 14 and a fixing tool 128 for fixing the head 14.

  As shown in FIGS. 4 and 5, the rail 122 is configured to have substantially the same length as the main building frame 14, and is arranged so as to extend in the depth direction of the gardening facility 10 along the main building frame 14. The The rail 122 is fixed to the purlin frame 14 by a fixture 128 at a plurality of locations in the longitudinal direction.

  As shown in FIG. 4, a plurality of runners 124 are provided on the rail 122 and can run along the rail 122. A hook 126 is suspended from each runner 124, and the hook 126 locks the locking member 116 of the moving frame 110 to the swingable material. In this way, the rail 122 supports the plurality of moving frames 110. Therefore, the moving frame 110 moves along the rail 122 in the depth direction of the horticultural facility 10.

(Curtain 130)
The configuration of the curtain 130 will be described with reference to FIGS. 3 to 5 again. The curtain 130 is attached to the moving frame 110 as shown in FIG. More specifically, the curtain 130 is connected to the lower part of the base frame 112 and the lower part of the auxiliary frame 114. By being connected in this way, the curtain 130 is attached over the entire width of the moving frame 110 along the shape of the moving frame 110. Further, as shown in FIG. 4, the curtain 130 is attached so as to cross between the moving frames 110 over the entire length of the rail 122 in the longitudinal direction.

  Further, as shown in FIG. 5, a plurality of slits 134 are formed in the curtain 130 at positions corresponding to the peaks of the moving frame 110. Each slit 134 is formed to extend between adjacent engaged portions 132. The slit 134 mainly prevents the folds of the curtain 130 from concentrating on a part of the curtain 130 when the curtain 130 is folded, prevents an increase in the tatami mat, and allows the curtain 130 to be folded neatly. is there. Further, the solar heat accumulated in the curtain 130 can be released by the slit 134.

(Operating means 200)
Next, the operation means 200 which is a characteristic part of the present embodiment will be described with reference to FIGS. The operation means 200 is provided on the left end in FIG. 4, that is, on the moving frame 110 disposed in front of the curtain 130 in the depth direction, and moves the moving frame 110 in the depth direction of the horticultural facility 10 along the support means 120. It is for moving.

  As shown in FIG. 3, the operating means 200 has a pair of left and right chains (suspending members) 202 whose upper ends are connected to the auxiliary frames 114 of the left and right inclined frames 111, and the lower ends of the pair of left and right chains 202. The operation frame 204 and the grip 206 provided on the operation frame 204 are configured. The suspension member is not limited to the chain 202, and may be a string, a cord, a tape, a wire, a hook, or the like, and the suspension length is not limited as long as the operation frame 204 can be connected.

  The upper ends of the pair of left and right chains 202 are swingably connected to the connecting portions 115 of the auxiliary frames 114 at the longitudinal center positions of the left and right inclined frames 111, and are suspended vertically. In addition, the lower ends of the pair of left and right chains 202 support both ends of the operation frame 204, so that the operation frame 204 can swing with respect to the auxiliary frame 114. The position where the pair of left and right chains 202 are connected to the auxiliary frame 114 is arranged such that the center of the operation frame 204 in the length direction (width direction of the gardening facility 10) is substantially coincident with the peak of the mountain shape of the moving frame 110. It is a position to be done.

  The connecting position of the chain 202 with respect to the auxiliary frame 114 can be moved by the connecting portion 115. Therefore, when the auxiliary frame 114 moves relative to the base frame 112, the upper end of the chain 202 is moved in the length direction of the inclined frame 111 by moving the connecting position of the chain 202 according to the movement amount of the auxiliary frame 114. It can be connected to the center position. In the present embodiment, the connection position of the chain 202 with respect to the auxiliary frame 114 is movable, but it may be fixed.

  The grip 206 is used to move the moving frame 110 in the depth direction of the horticultural facility 10 as will be described later by pushing or pulling the moving frame 110. The grip 206 is provided at the center in the length direction of the operation frame 204 (the width direction of the gardening facility 10). The center of the operation frame 204 in the length direction is the position of the moving frame 110 as described above. It almost coincides with the peak of Yamagata. Therefore, since the position of the grip 206 substantially coincides with the peak of the mountain shape of the moving frame 110, the center of the moving frame 110 can be pulled. For this reason, the inclination of the moving frame 110 is prevented during the opening / closing operation. Further, since the position at which the operation frame 204 pulls the moving frame 110 is the center position in the length direction of the left and right inclined frames 111, the inclination of the inclined frame 111 is prevented during the opening / closing operation.

  In the present embodiment, the operation means 200 is provided on the moving frame 110 disposed at the left end in FIG. 4, but the moving frame 110 on which the operation means 200 is provided is not limited to this example. For example, it can be appropriately designed such as being provided on the moving frame 110 arranged at the right end in FIG. 4 or being provided on the moving frames 110 at both ends. Furthermore, the moving frame 110 on the end side where the operation means 200 is not provided may be fixed so as not to move.

  As described above, since the operation unit 200 is configured to be connected to the left and right inclined frames 111 of the moving frame 110, the operation unit 200 can stably pull the two points of the moving frame 110. Therefore, since the left and right balance of the moving frame 110 can be pulled, the curtain 130 can be smoothly opened and closed as will be described later.

  Further, since it is only necessary to connect the operating means 200 to one moving frame 110 arranged at the left end in FIG. 4, a plurality of opening / closing devices are not required, and the burden of installation work and the installation cost can be reduced.

  The configuration of the curtain opening / closing device 100 has been described above. Next, the operation of the operation means 200 when the angle and width of the moving frame 110 are changed will be described with reference to FIGS. Here, the shape of the gardening facility 10 shown in FIG. A gardening facility having a shape different from the standard gardening facility 10 is a gardening facility 20 shown in FIG. 7 and a gardening facility 30 shown in FIG.

  In the horticultural facility 20 shown in FIG. 7, the inclination angle of the arch 22a of the arch frame 22 is larger than that of the standard shape, and the width between the side walls 22b is smaller. 8 has a larger inclination angle of the arch 32a of the arch frame 32 than that of the gardening facility 20, and the width between the side walls 32b is larger than that of the standard gardening facility 10. Yes.

  The moving frames 110 used in these three horticultural facilities 10, 20, and 30 are the same, and by changing the shape of the same moving frame 110, it corresponds to each horticultural facility 10, 20, and 30. I am letting. The shape of the moving frame 110 is changed so as to be symmetrical. Further, the operation means 200 used for the moving frame 110 is also the same, and is made to correspond by changing the attachment position of the same operation means 200 to the moving frame 110.

  The moving frame 110 has a larger inclination angle of the arch 22a of the arch frame 22 from the reference-type garden facility 10 shown in FIG. 6 than the reference-type garden facility 10 shown in FIG. The case where it uses for the garden facility 20 with a small width | variety is demonstrated.

(1) Horticultural facilities 10 (Fig. 6)
First, the case where the moving frame 110 is used for the standard garden facility 10 will be described. As shown in FIG. 6, the operation means 200 at this time is such that the pair of left and right chains 202 are vertically suspended from the left and right auxiliary frames 114 of the moving frame 110, and the position of the grip 206 is the peak of the mountain shape of the moving frame 110. Is almost in agreement with

(2) Horticultural facilities 20 (Fig. 7)
Next, the case where the moving frame 110 is used in the gardening facility 20 in which the inclination angle of the arch 22a of the arch frame 22 is larger than the reference-type gardening facility 10 and the width between the opposing side walls 22b is small will be described. .

  As shown in FIG. 7, when the moving frame 110 is used in the gardening facility 20, the inclination angle of the base frame 112 is increased, and the protruding length of the auxiliary frame 114 from the base frame 112 is shortened. Since the protruding length of the auxiliary frame 114 is shortened, the connection position between the pair of left and right chains 202 of the operation means 200 and the auxiliary frame 114 approaches in the horizontal direction. Therefore, the connecting portion 115 is moved in the distal direction of the auxiliary frame 114, and the connecting position of the pair of left and right chains 202 and the auxiliary frame 114 is moved in the distal direction of the auxiliary frame.

  Accordingly, the pair of left and right chains 202 can be vertically suspended from the left and right auxiliary frames 114 of the moving frame 110, and the position of the grip 206 can be made to substantially coincide with the peak of the mountain shape of the moving frame 110.

  Thus, even if the shape of the moving frame 110 changes, the connection position of the same operating means 200 to the auxiliary frame 114 is changed even if the shape of the moving frame 110 is changed for use in the gardening facility 20 having a shape different from that of the standard-type gardening facility 10. You can respond by simply changing it.

(3) Gardening facility 30 (FIG. 8)
Next, the moving frame 110 has a larger inclination angle of the arch 32a of the arch frame 32 than the horticultural facility 20 and has a larger width between the opposing side walls 32b than the reference horticultural facility 10. The case where it is used will be described.

  As shown in FIG. 8, when the moving frame 110 is used in the garden facility 30, the inclination angle of the base frame 112 is increased, and the protruding length of the auxiliary frame 114 from the base frame 112 is increased. Since the protruding length of the auxiliary frame 114 is increased, the connecting position between the pair of left and right chains 202 of the operating means 200 and the auxiliary frame 114 is moved away in the horizontal direction. Therefore, the connecting portion 115 is moved in the direction approaching the base frame 112, and the connecting position between the pair of left and right chains 202 and the auxiliary frame 114 is moved in the direction approaching the base frame 112.

  Accordingly, the pair of left and right chains 202 can be vertically suspended from the left and right auxiliary frames 114 of the moving frame 110, and the position of the grip 206 can be made to substantially coincide with the peak of the mountain shape of the moving frame 110.

  Thus, even if the width and angle of the chevron of the moving frame 110 change, it is only necessary to change the connection position of the operating means 200 to the moving frame 110, so that the same operating means 200 can cope with it.

  The operation of the operation unit 200 when the width and angle of the moving frame 110 are changed has been described above. Next, the operation of the curtain opening / closing device 100 will be described with reference to FIGS. FIG. 9 shows an operation for opening the curtain 130, and FIG. 10 shows an operation for closing the curtain 130.

(Operation of curtain opening / closing device 100)
First, the operation of opening the curtain 130 will be described with reference to FIG. Holding the grip 206 of the operating means 200 of the moving frame 110-1 disposed at the left end in FIG. 9A, the moving frame 110-1 is pushed rightward in FIG. As a result, the left end runner 124 connected to the left end moving frame 110-1 moves along the rail 122 in the right direction in FIG. 9.

  When holding the grip 206 and pushing the moving frame 110-1, the pair of left and right chains 202 can be pulled while maintaining the left and right balance of the moving frame 110-1. Therefore, the moving frame 110-1 moves smoothly. When the runner 124 of the moving frame 110-1 at the left end comes into contact with the runner 124 of the moving frame 110-2 adjacent to the right, the moving frames 110-1 and 110-2 move together.

  Thus, as the moving frame 110-1 at the left end moves in the right direction, the moving frame 110 disposed on the right side of the moving frame 110-1 sequentially moves integrally. Therefore, as shown in FIG. 9B, each moving frame 110 moves sequentially, and the curtain 130 is folded. Then, as shown in FIG. 9C, when all the moving frames 110 move to the right end portion of the rail 122, the curtain 130 is completely folded. In this way, the curtain 130 is opened.

  Next, the operation of closing the curtain 130 will be described with reference to FIG. Holding the grip 206 of the operating means 200 of the moving frame 110 disposed at the left end in FIG. 10A, the moving frame 110 is pulled in the left direction in the figure. As a result, the left end runner 124 connected to the left end moving frame 110 moves along the rail 122 in the left direction in the figure. As shown in FIG. 10B, when the curtain 130 between the moving frame 110 at the left end and the moving frame 110 adjacent to the right end is completely unfolded, the moving frame 110 adjacent to the right is pulled to the curtain 130. As a result, it moves integrally with the moving frame 110 at the left end.

  Thereafter, this operation is sequentially repeated by continuing the movement of the moving frame 110 at the left end. When the moving frame 110 at the left end moves to the left end of the rail 122, the curtain 130 is completely unfolded as shown in FIG. In this way, the curtain 130 is closed.

(Effect of the first embodiment)
As described above, according to the present embodiment, the operation means 200 is configured to be connected to the left and right auxiliary frames 114 of the moving frame 110 with respect to the moving frame 110 connected to the curtain 130. The means 200 can stably pull the two points of the moving frame. Therefore, since it is only necessary to connect the operation means 200 to one moving frame 110, a plurality of opening / closing devices are not required, and the burden of installation work and the installation cost can be reduced.

  In addition, since the pair of left and right chains 202 constituting the operation means 200 can be pulled while balancing the left and right of the moving frame 110, the curtain 130 can be opened and closed smoothly.

  In addition, since the center of the operation frame 204 and the apex of the mountain shape (substantially rounded shape) of the moving frame 110 are matched, the center of the operation frame 204 can be pulled. Accordingly, the tilt of the moving frame 110 can be prevented during the opening / closing operation.

  In addition, in this embodiment, when the shape of the moving frame 110 was changed, the connection position of the chain 202 was changed, but it is not limited to this example. The connection position of the chain 202 with respect to the moving frame 110 may be fixed. If the coupling position of the chain 202 with respect to the moving frame 110 is fixed, the chain 202 may support the operation frame 204 at an angle other than vertical when the shape of the moving frame 110 is changed.

  However, since the change of the shape of the moving frame 110 is performed symmetrically, even in this case, the center of the operation frame 204 in the length direction (the width direction of the gardening facility 10) is substantially the same as the peak of the mountain shape of the moving frame 110. It will be in a matching state. For this reason, the movement of the moving frame during the opening / closing operation is not hindered.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to this example. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.

  For example, in the above embodiment, the operating means is connected to one end of the curtain in the depth direction (that is, in front of the curtain in the depth direction), but the present invention is not limited to this example. For example, the operating means may be connected to the end of the curtain in the depth direction, or may be connected to both the front and back ends.

  Further, the end in the depth direction of the curtain to which the operation means is connected includes not the exact end but also the vicinity of the end.

  Further, the end of the curtain in the depth direction may be on either side in the case of a gardening facility having two entrances. Furthermore, in this case, if the operating means is connected to both the front and back ends of the curtain, the curtain can be easily operated regardless of which entrance is entered.

  In addition, although the direction in which the curtain is folded is defined as one direction of the depth direction, it may be folded in both directions, and the direction in which the curtain is folded may be changed as appropriate according to the situation.

  In the first embodiment, the base frame 112 has a mountain shape and the inclination angle of the mountain shape is variable. However, the present invention is not limited to this example. For example, the shape of the base frame 112 can be various shapes such as a straight line. Further, the angle of inclination of the mountain shape can be fixed.

  Further, the operation means 200 is configured to include a pair of left and right chains 202 whose upper ends are connected to the left and right inclined frames 111, and an operation frame 204 to which the lower ends of the respective chains 202 are connected.

For example, the traction means 610, 612, 614 is connected to the openings 136-1, 136-2, 136-3 of the curtain 130, or the portions other than the openings 136-1, 136-2, 136-3 of the curtain 130. Or may be connected to

  Moreover, in the said 3rd Embodiment, although the operation means 600 was connected with the connection part 616 of the three pulling means 610,612,614, this invention is not limited to this example. For example, the operation means 600 may be directly connected to the openings 136-1, 136-2, 136-3 of the curtain 130, the appropriate positions of the curtain 130, or the runners 124-1, 124-2, 124-3. . Moreover, the location and the number for connecting the operation means 600 can be designed as appropriate. Further, the traction means 610 is suspended for a long time, a position where the ends of the traction means 612 and 614 are connected to the traction means 610 at a midway height is defined as a connection portion 616, and a portion below the connection portion 616 is defined as an operation means 600. Also good.

  Moreover, in the said 3rd Embodiment, although the number of the traction means 610,612,614 was set to three, this invention is not limited to this example. For example, the number of traction means can be appropriately designed, such as the number corresponding to the number of rails 122 or the number corresponding to the size of the curtain 130.

  Moreover, in the said 3rd Embodiment, although the height of the connection part 616 of each traction means 610, 612, 614 was provided above the installation height of the edge part rails 122-2, 122-3. The present invention is not limited to this example. For example, the height of the connecting portion 616 between the traction means 610, 612, and 614 may be provided at the same height as the installation height of the end rails 122-2, 122-3, or may be provided below.

  In addition, the end portion in the depth direction of the curtain 130 on which the operation unit 600 hangs down may not be strictly an end portion but near the end portion.

  Moreover, in the said 1st-3rd embodiment, although the structure which opens and closes the installed curtain 130 was demonstrated simultaneously, the curtain 130 divided | segmented into right and left by the width direction center of the gardening facility 10 is divided into right and left separately. You may make it open and close. This application example will be described by taking the third embodiment as an example. For example, as shown in FIG. 17, two central rails 122-1 are arranged in the center of the gardening facility 10, and one central rail is provided. The left and right curtains 130 are supported by 122-1 and end rails 122-2 facing each other. And the operation means 600 which has the same function as 3rd Embodiment is provided in the right-and-left curtain 130. FIG. With such a configuration, when one operation means 600 is pulled, only one curtain 130 opens and closes as shown in FIG. Thereby, it becomes possible to open and close only a part of the curtain 130 according to the time zone and the presence or absence of sunlight. Further, the left and right curtains 130 can be opened and closed simultaneously by pulling the left and right operation means 600 simultaneously or by connecting and pulling the left and right operation means 600. In addition, the number of dividing the curtain 130 is not limited to two, and can be designed as appropriate. The central rail 122-1 is exemplified by a configuration in which two rails are arranged side by side. It can also be constituted by one central rail arranged in parallel.
