Description

Technical Field

[0003] , , , , ,

[0001] The present invention relates to a ventilation member for a gardening tunnel that covers an object with a covering material.

Background Art

[0002] A gardening tunnel has a structure in which an arch-shaped support is covered with a covering material such as vinyl, and a heat retention effect can be obtained even in a low-temperature environment at night. On the other hand, during the day, due to sunlight, the inside of the tunnel becomes a high-temperature environment, so the hem part is lifted to ventilate. This ventilation work requires raising and lowering the covering material with a pole, which places a large labor burden on the operator. So far, automation of hem ventilation using temperature changes (Patent Documents 1 to 3) and methods of changing the basic structure of the tunnel (Patent Documents 4 to 11) have been considered. Patent Documents 4 to 6 propose a bellows-type opening and closing, Patent Documents 7 and 8 propose an upper opening and closing type, and Patent Documents 9 to 11 propose a ventilation by drilling holes.

Example

[0012] Hereinafter, the ventilation member of the gardening tunnel according to an embodiment of the present invention will be described. Figure 1 is a conceptual diagram showing a ventilation member for a horticultural tunnel according to this embodiment. Figure 1(a) is a conceptual perspective view showing the operating state of the ventilation member, Figure 1(b) is a side view showing the horticultural tunnel in a state where it is insulated by the ventilation member, Figure 1(c) is a side view showing the ventilation member in the middle of operation, and Figure 1(d) is a side view showing the horticultural tunnel in a state where it is ventilated by the ventilation member. In this embodiment, the ventilation member 10 of the horticultural tunnel 3 is used in a part of the horticultural tunnel 3, in which a plurality of arc-shaped support posts 1 are erected along the furrow at predetermined intervals, and a covering sheet 2 is placed over the plurality of support posts 1 to cover the furrow. Note that the ventilation member 10A shown in Figure 1(a) is the ventilation member 10 in the state shown in Figure 1(b), the ventilation member 10B shown in Figure 1(a) is the ventilation member 10 in the state shown in Figure 1(c), and the ventilation member 10C shown in Figure 1(a) is the ventilation member 10 in the state shown in Figure 1(d). Thus, Figure 1(a) shows the ventilation member 10 in three different states.

[0013] The ventilation member 10 of the gardening tunnel 3 according to this embodiment has a main frame member 11 that is arc-shaped along the covering sheet 2, at least when placed in the gardening tunnel 3, and the main frame member 11 has a first main frame member 11X and a second main frame member 11Y. The ventilation member 10 has a covering material 12 between the first main frame material 11X and the second main frame material 11Y, and connects one end 11a of the first main frame material 11X to one end 11a of the second main frame material 11Y with a support material 13. When the horticultural tunnel 3 is kept warm, the support material 13 is placed at the bottom edge of one side of the covering sheet 2, and the other end 11b of the first main frame material 11X and the other end 11b of the second main frame material 11Y are placed at the bottom edge of the other side of the covering sheet 2. The gardening tunnel 3 is made ventilated by using the other end 11b of the first main frame member 11X and the other end 11b of the second main frame member 11Y as fulcrums, and by separating the support member 13 from the bottom edge of one side of the covering sheet 2. In this way, by separating the support material 13 from the bottom edge of one side of the covering sheet 2, the horticultural tunnel 3 can be changed from a heated state to a ventilated state. This eliminates the need to manually open and close the bottom edge of the covering sheet 2, and allows for easy switching between a heated state and a ventilated state.

[0014] The ventilation member 10 has a handle portion 14 near the center in the longitudinal direction of the main frame material 11. By providing the handle portion 14 on the main frame material 11, the work of separating the support material 13 from the bottom edge on one side of the covering sheet 2 can be performed in an upright position. It is preferable that the handle portion 14 be provided at the center in the longitudinal direction of the main frame material 11, or at a position slightly offset from the center in the longitudinal direction of the main frame material 11 toward one end 11a of the main frame material 11. Furthermore, the ventilation member 10 is provided with a fastener 15 on the covering material 12 located between one end 11a of the first main frame material 11X and one end 11a of the second main frame material 11Y. For example, hook-and-loop fasteners are suitable for the fastener 15. By using hook-and-loop fasteners as the fastener 15, the fastener 15 can be easily locked and unlocked. Magnets can also be used for the fastener 15. The ventilation member 10 maintains the position of the support member 13 at one side of the hem of the covering sheet 2 by locking the fastener 15, and can move the support member 13 away from one side of the hem of the covering sheet 2 by releasing the fastener 15. By providing such fasteners 15, it is possible to prevent the main frame material 11 and the covering material 12 from being lifted by the wind, and to maintain the horticultural tunnel 3 in a warm state.

[0015] Furthermore, the ventilation member 10 is provided with locking members 16 on one end 11a side of the first main frame member 11X and on one end 11a side of the second main frame member 11Y. In this embodiment, a support member 13 connecting one end 11a of the first main frame member 11X to one end 11a of the second main frame member 11Y has been described. However, it is preferable to connect the other end 11b of the first main frame member 11X to the other end 11b of the second main frame member 11Y with the support member 13. Furthermore, by connecting the position of the handle portion 14 of the first main frame member 11X to the position of the handle portion 14 of the second main frame member 11Y with the support member 13, the structural strength of the ventilation member 10 can be increased, and the operation of the ventilation member 10 can be made stable. Furthermore, the fastener 15 may be provided together with the covering material 12 located between one end 11a of the first main frame material 11X and one end 11a of the second main frame material 11Y, or, instead of the covering material 12 located between one end 11a of the first main frame material 11X and one end 11a of the second main frame material 11Y, it may be provided on one end 11a of the first main frame material 11X and one end 11a of the second main frame material 11Y, or on the support material 13.

[0016] Figure 2 is a side view showing other operating states of the same ventilation component. Note that the ventilation member 10B shown in Figure 2 is in the same state as the ventilation member 10B shown in Figure 1(a), while the ventilation member 10D shown in Figure 2 is in a different state than the ventilation member 10 shown in Figure 1(a). As shown in Figure 2, the ventilation member 10D holds the main frame member 11, the covering material 12, and the support member 13 in the gardening tunnel 3 by a locking member 16, with the support member 13 spaced apart from the bottom edge of one side of the covering sheet 2. Therefore, in a ventilated state, the covering material 12 can be kept away from the ground, preventing soiling of the covering material 12 and not becoming an obstacle for workers moving along the ridges. Furthermore, as shown in the figure, it is preferable that the ventilation member 10 has a stopper 17 that holds the main frame material 11 in the gardening tunnel 3 when it is in a ventilated state. In this way, the stopper 17 can hold the main frame material 11, which is in a ventilated state, in an upper position above the gardening tunnel 3. Therefore, in a ventilated state, the covering material 12 can be kept away from the ground, preventing the covering material 12 from getting dirty and not becoming an obstacle for workers moving along the ridges.

[0017] Figure 3 is a conceptual diagram showing a ventilation member for a horticultural tunnel according to another embodiment of the present invention. As shown in the figure, it is preferable that the stopper 17 be a connecting member that connects the main frame material 11 and the support column 1. By providing such a stopper 17, it is possible to prevent the main frame material 11 from detaching from the gardening tunnel 3 and being blown away and lost due to wind. The ventilation member 10 has a handle portion 14 near the center in the longitudinal direction of the main frame material 11, and a locking member 16 on one end 11a of the main frame material 11. When ventilated, the locking member 16 is locked to the handle portion 14. Thus, in a ventilated state, the locking member 16 can be locked to the handle portion 14, allowing the support member 13 to be separated from one side of the bottom edge of the covering sheet 2 while standing. Furthermore, in a ventilated state, the covering material 12 can be kept separated from the ground, preventing soiling of the covering material 12 and not becoming an obstacle for workers moving along the ridges. The handle portion 14 consists of a mounting portion 14a attached to the frame material 11, a rising portion 14b rising from the mounting portion 14a, a grip portion 14c extending at a different angle from the tip of the rising portion 14b, a rising portion 14d extending parallel to the rising portion 14b from the tip of the grip portion 14c, and a retaining portion 14e extending parallel to the grip portion 14c from the tip of the rising portion 14d, with a space formed between the retaining portion 14e and the mounting portion 14a. The handle portion 14 is then positioned on the main frame material 11 such that the rising portion 14b is on one end 11a side of the main frame material 11. By using such a handle portion 14, the ease of locking the locking member 16 to the handle portion 14 can be improved.

[0018] Figure 4 shows the installation of the ventilation member according to this embodiment. As shown in Figure 4, the ventilation member 10 of the horticultural tunnel 3 in this embodiment is installed at a position where a portion of the bottom edge of the covering sheet 2 is separated from the ground. In this way, by using the ventilation member 10 at a position where a part of the bottom edge is lifted from the ground, a part of the bottom edge of the covering sheet 2 arranged along the ridge is lifted from the ground to create a ventilated state, and the main frame material 11 is constructed so as to cover the ventilated bottom edge with the covering material 12, and by covering the horticultural tunnel 3 with the covering material 12, a heat retention state can be created, and by lifting the support material 13 from one side of the bottom edge of the covering sheet 2, the state can be changed from a heat retention state to a ventilated state.

[0019] Furthermore, even if the main frame material 11 described in the above embodiment is maintained in an arch shape, it may also be elastic and therefore deformable during use. Furthermore, when the purpose of the covering sheet 2 and covering material 12 is to retain heat, generally a light-transmitting film such as a polyethylene sheet, a polyvinyl chloride sheet, or a special polyolefin sheet is used. However, when the purpose is to block light, repel insects, protect against cold, or protect against frost, light-selective covering materials such as cheesecloth, colored film, ultraviolet-controlled film, or infrared-controlled film are used. In addition, covering materials 12 such as insect nets, shading nets, or nonwoven fabrics can also be used. [Industrial applicability]

[0020] This invention can be used in protected horticulture, not only in open fields but also in greenhouses and indoors, and can be used not only for ridge cultivation but also for pot cultivation and hydroponics, thereby reducing the workload of workers. [Explanation of Symbols]
