Description

[Technical field]

[0001] The present invention relates to a rain shelter device for sheltering cultivated plants from rain. [Background technology]

[0002] For example, one of the important points in cultivating tomatoes is to provide adequate shelter from the rain, as excessive rain during cultivation can make the plant susceptible to diseases, such as causing the tomato fruit to crack.

[0003] Patent Documents 1 and 2 disclose examples of rain shelter devices having a simple structure that are provided to protect cultivated plants from rain.

[0004] The rain shelter described in Patent Document 1 is configured to attach a transparent rain shelter cover to the top of the plants in the planter in the shape of a flat roof using fixing devices.The rain shelter described in Patent Document 2 is configured to attach a small parasol cover to the top end of a support pole erected on the ground or in the planter.

[0005] However, if such a rain cover is applied to tomato cultivation in a planter, it can protect the tomatoes from rain falling from above, but cannot protect them from rain falling from the side. This can result in the tomatoes being exposed to a lot of rain, which can easily lead to diseases. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS EXAMPLES

[0017] 1-3, a rain shelter device (hereinafter referred to as rain shelter device) 1 for sheltering cultivated plants according to the present invention is applied as a rain shelter device for sheltering plants (for example, tomatoes, not shown) cultivated in a planter (flower pot in the figure) 2 from rain, and has one or more (three in this embodiment) supports 5, 5, 5 and an umbrella member 7 connected to upper ends 6, 6, 6 of the supports 5, 5, 5 and arranged to cover the upper part of the plant. The umbrella member 7 allows rainwater that falls on its upper surface portion 9 to flow down as shown by arrows in Figs. 1-2 and is discharged at its lower edge portion 10, and as shown in Fig. 3, a required portion of the lower surface portion 11 of the umbrella member 7 is connected to the upper ends 13, 13, 13 of the supports 5, 5, 5 that are erected as described above. As shown in Figures 2 and 3, a sheet fixing portion 20 is provided on the underside portion 11 of the umbrella member 7, slightly inside the outer circumferential edge 16 of the lower peripheral portion 15 of the umbrella member 7, for removably attaching an upper edge portion 19 of a translucent rain protection sheet 17.

[0018] As shown in Figs. 1 and 2, the rain protection sheet 17 is attached so as to surround the inner portion 25 of the umbrella member 7, which is inward from the lower edge 10, in the circumferential direction, and can cover the plant in the circumferential direction. The upper edge portion 19 of the rain protection sheet 17 has a required portion 23, as viewed in the circumferential direction, detachably fixed to the sheet fixing portion 20, and the entire upper edge 24 of the rain protection sheet 17 is located in the inner portion 25 (Figs. 2 and 7) which is inward from the lower edge 10 (Fig. 3) of the umbrella member 7. As a result, rainwater that flows down the upper surface portion 9 of the umbrella member 7 and is discharged at the lower edge 10 flows down the outer surface 26 of the rain protection sheet 17, but does not flow down the inner surface 27 of the rain protection sheet 17. This will be described in detail below.

[0019] In this embodiment, as shown in Figs. 1 to 6, the umbrella member 7 has an upwardly protruding flat disk shape, and its upper surface 9 and its lower surface 11 are formed into an upwardly protruding spherical shape, and as shown in Figs. 2 and 4, the lower peripheral portion 15 of the umbrella member 7 is curved downward relatively more strongly than the upper portion 31 above it.

[0020] The diameter of the umbrella member 7 is set to about 400 mm, for example. And, in the lower peripheral portion 15 of the umbrella member 7, as shown in Fig. 4, six insertion holes 32 penetrating in the up-down direction are provided at a required angular pitch in the circumferential direction of the outer periphery 16, that is, at an angular pitch of 60 degrees in this embodiment.

[0021] In this embodiment, as shown in Figures 4 and 5, the insertion hole 32 is configured as a hole portion in which a first hole portion 33 having a circular shape in a planar view is connected to the upper end of the first hole portion 33 and an enlarged second hole portion 35 having a diamond shape in a planar view.

[0022] In this embodiment, the seat fixing part 20 is configured with a fixed shaft part 36 having a vertically long cylindrical shape as shown in Figures 4 and 6. As shown in Figures 4 and 6, the fixed shaft part 36 has a shaft part 37 having a circular cross section that can be inserted into the first hole part 33 (Figures 4 to 5), and an outer surface part 38 at the lower end of the shaft part 37 is provided with a rectangular plate-shaped locking protrusion 39 that can be inserted into the second hole part 33, and an inner surface part 40 is provided with a split groove 41 that is open at the lower end and extends vertically over the entire length.

[0023] The upper end 42 of the shaft 37 is provided with a locking head 45 having a diamond shape in a plan view, protruding outward from the upper end periphery of the shaft 37. By inserting the shaft 37 into the first hole 33 and fitting the locking head 45 into the second hole 35, as shown in Fig. 4, the upper surface 47 of the locking head 45 is flush with the upper surface 9 of the umbrella member 7. As shown in Fig. 3, the fixed shaft 36 protrudes downward from the lower surface 11 of the umbrella member 7, and the locking head 39 fitted into the second hole 35 makes the insertion hole 32 waterproof. The diameter of the shaft 37 is set to about 7 mm, for example, and the downward protrusion of the shaft 37 from the lower surface 11 of the umbrella member 7 is about 43 mm.

[0024] When the shaft portion 37 is inserted into the insertion hole 32, the split groove 41 is elastically deformed and the groove width becomes smaller, thereby allowing the shaft portion 37 to be inserted into the insertion hole 32. Therefore, there is no risk that the shaft portion 37 inserted into the insertion hole 32 will inadvertently fall out of the insertion hole 32.

[0025] The lower surface 11 of the umbrella member 7 is provided with a connecting recess 50 into which the upper end 13 of the support 5 is press-fitted. In this embodiment, the connecting recesses 50 are arranged at an angular pitch of 120 degrees on concentric circles having diameters of 104 mm, 127 mm, and 150 mm, each of which is radially arranged around the center of the umbrella member 7, as shown in Fig. 7 for example.

[0026] In this embodiment, three support poles 5 are used, and the upper ends 13 of the support poles 5 are press-fitted into three connecting recesses 50 selected according to the size of the planter 2 (Fig. 3), so that the umbrella member 7 is in an upright state on the planter 2 via the three support poles 5, 5, 5 as shown in Fig. 1. The height of the upper end of the umbrella member 7 is set to about 130 cm from the top of the planter 2, for example.

[0027] In this embodiment, as shown in Fig. 1, adjacent supports 5, 5 are connected to each other at a required height position, for example, at three points above and below, by connecting rod members 51 to form a triangular connecting frame 51a. The support frame body 52 thus formed supports the umbrella member 7 in a stable state, and the umbrella member 7 is installed in a stable state above the planter 2 via the supports 5, 5, 5. Since the connecting member 51 has the function of attracting plants and also the function of supporting tomatoes, the connecting member 51 is appropriately positioned at a required height position of the support 5 according to the growth of the plants in the planter 2.

[0028] As shown in Fig. 8, the connecting rod member 51 is connected to the support pillar 5 by elastically fitting C-shaped clamping portions 53 provided on both ends of the connecting rod member 51 into the support pillar 5. In Fig. 1, the connecting rod member 51 is shown by a thick straight line and a thick chain line, and the C-shaped clamping portions 53 are not shown.

[0029] The upper end portions 13 of the pillars 5 may be press-fitted into the connecting recesses 50 provided on the lower surface portion 11 of the umbrella member 7 for each pillar 5, but can also be press-fitted as follows. That is, the pillars 5, 5 are connected to each other with the connecting rod member 51, and the arrangement of the three pillars 5, 5, 5 is set as required, so that the upper end portions 13, 13, 13 of the three pillars 5, 5, 5 can be simultaneously aligned with the three connecting recesses 50, 50, 50 arranged in the circumferential direction. Therefore, the upper end portions 13, 13, 13 of the three pillars 5, 5, 5 can be simultaneously aligned with the three connecting recesses 50, 50, 50, and the press-fitting can be easily performed.

[0030] As shown in Figs. 1-2 and 7, the rain protection sheet 17 is attached to the inner part of the umbrella member 7 that is inward from the lower edge part 10 (Fig. 2) in the circumferential direction, so as to surround the inner part, and can cover the plant in the circumferential direction. With the rain protection sheet 17 attached in this manner, the upper edge part 19 of the rain protection sheet 17 is detachably fixed to the shaft part 37 by a fastener 55 in a state where it wraps the shaft part 37 from the outside, as shown in Figs. 2 and 10(B). In this embodiment, the fastener 55 is configured as a packer consisting of a C-shaped clamping part 56 that can be elastically expanded, as shown in Figs. 4 and 10(B), and when attached to the shaft part 37, its lower end 57 abuts against the locking protrusion 39 as shown in Figs. 2-3, so that it is prevented from falling off from the lower end of the shaft part 37.

[0031] As described above, when the rain protection sheet 17 surrounds the inner portion 25 (FIG. 7), the entire upper edge 24 of the rain protection sheet 17 is located slightly inside the lower edge 10 of the umbrella member 7 (for example, located at the inner portion 25 about 8 mm inside) as shown in FIG. 2. As a result, the rain protection sheet 17 is attached to the umbrella member 7 in a cylindrical shape so as to cover the plant in the circumferential direction, and its lower edge 59 (FIG. 1) is located, for example, about 100 cm below the upper edge 24 (FIG. 2). Therefore, the lower edge 59 of the rain protection sheet 17 is located at a height of about 30 cm from the upper end 62 of the planter 2.

[0032] In this state, the lower end 64 of the cylindrical rain protection sheet 17 is in an open state, so that the internal space 65 formed by being surrounded by the rain protection sheet 17 is ventilated through the open lower end 64.

[0033] As a result, when it rains, rainwater that has flowed down the upper surface 9 of the umbrella member 7 flows down the outer surface 26 of the rain protection sheet 17 of the umbrella member 7, and does not flow down the inner surface 27 of the rain protection sheet 17. This prevents the flowing rainwater from entering the inside of the rain protection sheet 17 and coming into contact with the tomatoes.

[0034] This is possible because, as described above, the shaft portion 37 is protruding downwardly inside the lower edge portion 10 of the umbrella member 7, for removably attaching the upper edge portion 19 (Figure 2) of the rain protection sheet 17, and the upper edge portion 19 of the rain protection sheet 17 is fixed to the shaft portion 37.

[0035] If the upper edge 24 of the rain protection sheet 17 were removably attached to the lower edge 10 of the umbrella member 7 as shown in Figure 11, rainwater flowing down the upper surface 9 of the umbrella member 7 would enter between the upper edge 24 and the lower edge 10 28 (Figure 11 (B)) as shown by the arrow in the figure and flow down the inner surface 27 of the rain protection sheet 17, which would make it impossible to prevent rain from coming into contact with the tomatoes.

[0036] As a result of the present invention, tomatoes that are less likely to crack due to rain can be grown.

[0037] The seam 69 (FIG. 9(A)) between both edge portions 66, 66 of the rain protection sheet 17 as viewed in the circumferential direction is secured by the shaft portion 37 and the fastener 36 as described based on FIG. 10 in this embodiment, but when necessary, such as when harvesting fruit, the fastener 55 fastened to the shaft portion 37 at the seam 69 is removed. By this removal, the rain protection sheet 17 is rolled up in the circumferential direction (clockwise or counterclockwise) to a necessary extent as shown by the dashed line in FIG. 9(A) and as shown in FIG. 12 to form an opening 70. Since six shaft portions 37 are attached at an angle pitch of 60 degrees in this embodiment as described above, if the fastener 55 for one shaft portion 37 is removed, the space up to the shaft portion 37 on the next side of the hexagon can be opened. Therefore, by removing the fasteners 55, 55, 55 from the three shafts 37, 37, 37, for example, in a clockwise or counterclockwise direction, a large opening 70 is formed, and the fruit can be harvested, as shown in Fig. 12. In this way, the fact that fruit can be harvested by partially removing the fasteners without removing all of the fasteners 55 is one of the advantages of the invention according to this embodiment.

[0038] The rolled-up portion of the rain protection sheet 17 is then fixed to the fixed shaft portion 36 by fastening with the fasteners 55 in the same manner as described above. The fasteners 55 that were removed can be re-fastened in a state in which the three fasteners that have not been removed are arranged side by side, so that the fastening operation can be easily performed. EXAMPLES

[0039] The present invention is by no means limited to the above-mentioned embodiment, and it goes without saying that various design modifications are possible within the scope of the claims. Examples thereof are as follows.

[0040] (1) When the umbrella member 7 has a disk shape, its diameter is set as required depending on the extent to which it spreads outward of the plant to be cultivated in the planter 2, and can usually be set to 300 to 800 mm.

[0041] (2) The number of the support pillars 5 is set so that the rain shelter device 1 constructed using the support pillars 5 has a required strength. The number of the support pillars 5 is not limited to three, and may be more than three, for example, four. Conversely, the number may be one, as long as the umbrella member 7 can be supported upright in a stable state. In addition, the connection portion of the support 5 to the underside portion 11 of the umbrella member 7 is set so that the rain shelter device 1 exhibits the required strength. For example, when there is only one support 5, it is removably fixed to the central portion of the underside portion 11 of the umbrella member 7, for example, via the connecting recess 50.

[0042] (3) The fixed shaft portion 36 may be provided integrally with the umbrella member 7. In this case, for example, the fixed shaft portion 36 is provided integrally and protrudes downward slightly inside the outer circumferential edge 16 of the lower surface portion 11 of the umbrella member 7.

[0043] (4) The shape of the umbrella member 7 in a plan view is not limited to the circular shape described above, and may be a triangular, rectangular, hexagonal, octagonal, etc., so long as there is a water gradient on the upper surface 9 of the umbrella member 7 and rainwater that falls on the upper surface 9 flows down and is discharged at the lower edge 10, thereby providing protection from the rain.

[0044] (5) The means for detachably fixing the required portion of the upper edge portion 19 of the rain protection sheet 17 to the sheet fixing device 20 is configured as required according to the shape of the sheet fixing device 20, which is configured, for example, in a shaft, plate, ring, hook, etc. For example, when the sheet fixing device 20 is configured as a fixed shaft portion 36, the fixing means may be configured as a packer consisting of the C-shaped clamping portion 56 described above, or may be configured to be clamped by a spring action between the tip portions of two openable and closable plate-like bodies, such as a clothespin-like clip.

[0045] (6) The required portion of the underside portion 11 of the umbrella member 7 which is connected to the upper end portion 13 of the support 5 may be the central portion or a portion toward the central portion of the underside portion 11, or may be any other portion which does not interfere with protecting the plants from rain during cultivation.

[0046] (7) A connecting protrusion may be provided on the underside 11 of the umbrella member 7 to be press-fitted into a connecting recess in an upper end opening provided at the upper end of the support 5, and the umbrella member 7 may be connected to the upper end of the support 5 by connecting the connecting protrusion to the connecting recess. Also, the means for attaching the upper end 13 of the support 5 to the umbrella member 7 may be a screwing means.

[0047] (8) In the present invention, the umbrella member 7 is connected to, for example, the upper end 13 of a support pole 12 that is erected in a planter. As described above, the support pole 12 may be a support pole that is erected by inserting its lower end portion into the cultivation soil in the planter, or it may be a support pole that is erected by holding its lower end portion in a support lower end holding piece provided on the side wall of the planter. The support 5 may be a support erected on a planter setting stand 75 for placing the planter thereon. The support 5 may be a support that is erected by sticking its lower end portion into the ground. When the support 5 is erected by sticking its lower end portion into the ground, the rain shelter device 1 according to the present invention can provide rain shelter for plants grown on the ground.

[0048] (9) In the above embodiment, in order to ventilate the internal space formed by arranging the rain protection sheet 17 so as to surround the plant circumferentially, the lower edge 59 of the rain protection sheet 17 is positioned at a height of about 30 cm from the upper end 62 of the planter 2. However, in order to ensure effective ventilation, it is preferable to position the lower edge 59 of the rain protection sheet 17 at least 10 cm above the upper end 62 of the planter 2. Also, when the support pole 5 is erected by sticking its lower end into the ground, it is advisable to position the lower edge of the rain protection sheet at least 10 cm above the ground in order to ventilate the internal space.

[0049] (10) The upper edge portion 19 of the rain protection sheet 17 is attached to the lower peripheral portion 15 (FIG. 3) of the umbrella member 7 and is wound in a circumferential direction to form a cylinder. The lower end portion of the rain protection sheet 17 may cover the outer surface of the upper portion of the planter. This allows the rain to be completely blocked if necessary for the plants. Also, in areas where the nights are cold, it can provide frost protection and a greenhouse effect. In this case, when ventilating the space covered by the rain protection sheet, the lower portion of the rain protection sheet is folded up and the folded up state is maintained with a clip or the like.

[0050] (11) The rain shelter device 1 for a planter according to the present invention can be applied to the cultivation of plants other than tomatoes that are easily damaged by heavy rainfall, such as eggplants and peppers. [Explanation of symbols]
