Description

[Technical field]

[0001] The present invention relates to a shade plate used for planting, and more particularly to a shade plate for planting that shades light emitted from a planting light used on a planting shelf. [Background technology]

[0002] Traditionally, the most common method of growing agricultural crops was soil cultivation, in which crops are grown by plowing farmland. In recent years, however, hydroponic cultivation, in which crops are grown indoors on shelves, has been attracting attention. In addition, while "water, air, moisture, nutrients, and a certain temperature suitable for growth" are essential for growing plants, in order to create an environment equivalent to that outdoors when growing plants indoors, LED lights, fans, water circulators, etc. are installed in designated places on the shelves and used as appropriate. However, when LED lights are constantly turned on indoors, depending on where they are installed, there are problems such as the light on the shelves being brighter than the room, or the light shining into people's eyes and being dazzling.Also, there is the problem that LED lights, which have a strong tendency to propagate in a straight line, have a narrow light distribution angle, making it difficult to illuminate the entire plant.

[0003] In order to solve the above problems, a technique has been proposed in JP 2014-183747 A (Patent Document 1). Specifically, the technique proposes a multi-tiered cultivation device that uses a light reflector to reflect light so that the light can be irradiated onto cultivated plants on a cultivation shelf.

[0004] However, the technical proposal described in Patent Document 1 had the problem that although it was possible to make the plants themselves reflect sunlight, it was not possible to reflect or block the LED light shining from directly above the shelf.

[0005] The applicant came up with the idea of ​​creating a reflective plate such as the one described above that would reflect the light of a light installed on a cultivation shelf for growing plants towards the plants, while also appropriately blocking light that is directed outside the shelf.He focused on the technology of an arm that can move freely while holding the plate with a clip, and developed a shading plate that has an attachment part that can be clamped to the cultivation shelf, and is composed of a reflective surface that reflects light and a shading surface that blocks light, which has led to the proposal of the ``shading plate for planting'' of the present invention.

[0006] [Patent Document 1] JP 2014-183747 A Summary of the Invention [Problem to be solved by the invention]

[0007] In view of the above problems, the present invention has an object to provide a light-shielding plate that comprises a reflective surface that reflects light and a light-shielding surface that blocks light, and has an attachment portion that can be clamped to a cultivation shelf. [Means for solving the problem]

[0008] In order to solve the above problems, the present invention provides a light-shielding plate that is attached to an indoor planting shelf, comprising a plate body having a required width, height, and thickness, and at least one or more mounting devices for attaching the plate body to the planting shelf, wherein the plate body comprises a reflective surface on one side that reflects light, and a light-shielding surface on the other side that blocks light, and the mounting devices comprise a first clamping portion that clamps the plate body, a second clamping portion that clamps the planting shelf, and a bending portion provided between the first clamping portion and the second clamping portion, and by clamping the second clamping portion at a predetermined location on the planting shelf so that the plate body is positioned in the open side portion of the planting shelf, the plate body reflects light within the planting shelf inward and suppresses leakage to the outside.

[0009] The present invention also employs a means in which the reflecting surface is mirror-shaped.

[0010] Furthermore, the present invention provides a method in which the reflective surface is colored and glossy.

[0011] Furthermore, the present invention employs a means in which the first clamping portion and / or the second clamping portion is subjected to an anti-slip treatment.

[0012] Furthermore, the present invention employs a means in which the light-shielding surface is subjected to a matte finish.

[0013] Furthermore, the present invention employs a means for bending the plate body at a predetermined location.

[0014] Furthermore, the present invention employs a means in which the plate body is provided with a slide plate having the same structure as the plate body. Effect of the Invention

[0015] According to the planting shade plate of the present invention, one side of the plate body is formed as a reflective surface that reflects light, and the other side is formed as a shading surface that blocks light, thereby enabling reflection and shading with just one plate body, and by clamping the mounting fixture to the planting shelf, it is possible to shade any desired area while illuminating the plants in the planting shelf with reflected light, thereby achieving the excellent effect of the above.

[0016] In addition, the plant cultivation shade plate of the present invention has a mirror-shaped reflective surface, which allows the light from a plant growth light to be reflected sufficiently, and reflection from the mirror surface makes it possible to illuminate areas that cannot be illuminated from directly above with an amount of light similar to that of the light.

[0017] Furthermore, according to the plant cultivation shade of the present invention, the reflective surface is colored, making it possible to reflect and irradiate light to plants in accordance with the color of the reflective surface, and by gloss-finishing the reflective surface, the reflectance of the reflective surface is increased compared to its untreated state, making it possible to reflect light from the light on the surface of the reflective surface and provide sufficient light to the plants.

[0018] Furthermore, according to the plant cultivation shading plate of the present invention, the first clamping portion and / or the second clamping portion is provided with an anti-slip coating, thereby preventing the plant cultivation shading plate from falling off from the portion clamped by the mounting portion.

[0019] Furthermore, according to the plant cultivation shading plate of the present invention, the shading surface is matte-finished, making it possible to reduce reflection of light irradiated from outside the planting shelf toward the shading surface.

[0020] Furthermore, according to the planting shade plate of the present invention, the plate body can be bent at specified locations, making it possible to direct the light reflected into the planting shelf in multiple directions and making it easier to secure working space during work.

[0021] Furthermore, according to the plant cultivation shading board of the present invention, the board body is provided with a slide board having the same structure as the board body, making it easy to adjust the shading range. [Brief description of the drawings]

[Diagram 2] FIG. 2 is an explanatory diagram showing a mode of use of the plant cultivation shading plate according to the present invention. [Diagram 3] FIG. 4 is an explanatory diagram showing another embodiment of the plant cultivation shading plate according to the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] The planting shade plate 1 of the present invention is attached to a planting shelf 15, and its greatest feature is that it reflects light from a light 17 provided on the planting shelf 15 into the planting shelf 15 while shading light to the outside of the planting shelf 15. Hereinafter, an embodiment of a plant cultivation shading board 1 according to the present invention will be described with reference to the drawings.

[0024] Furthermore, the plant cultivation shade plate 1 of the present invention is not particularly limited to the embodiments described below, and can be appropriately modified within the scope of the technical idea of ​​the present invention, i.e., within the range of shapes, dimensions, materials, etc. that can achieve the same functional effects.

[0025] FIG. 1 is an explanatory diagram showing an embodiment of a plant cultivation shading board 1 according to the present invention, in which (a) shows a state in which the reflective surface 5 of the board body 2 faces the front, (b) shows a state in which the shading surface 6 of the board body 2 faces the front, and (c) shows a state in which the lower part of the board body 2 faces the front. FIG. 2 is an explanatory diagram showing a mode of use of the plant cultivation shading board 1 according to the present invention. FIG. 3 is an explanatory diagram showing another embodiment of the plant cultivation shading board 1 of the present invention, in which (a) shows an embodiment in which a bending member 7 is provided at a predetermined location of the board body 2, and (b) shows an embodiment in which a sliding member 8 and a sliding board 9 are provided on the shading surface 6 of the board body 2. The plant cultivation shading board 1 according to the present invention is mainly composed of a board body 2 and a mounting fixture 3, and is attached to a plant cultivation shelf 15. In addition, "planting" in this text is an abbreviation for plant cultivation. In addition, "light" in this text refers to light sources for planting, including LED lights and incandescent lights.

[0026] The planting shelf 15 refers to a shelf that is mainly used for indoor planting. The main structure of the planting shelf 15 may be a conventionally known shelf structure and is not particularly limited. The planting shelf 15 is provided with one or more shelves 16, and pots or containers in which plants to be cultivated (hereinafter referred to as "planted plants 4") are placed on the top surfaces of the shelves 16. Therefore, the length and width of the shelves 16, the height between the shelves 16 (the height of the planting space), and the size of the planting shelf 15 that houses the shelves 16 are appropriately selected depending on the type and size of the plant 4 to be cultivated.

[0027] 2, in order to supply the planted plant 4 with the necessary light, lights 17 are provided at predetermined locations (mainly the bottom surface) of another shelf board 16B above the shelf board 16A on which the planted plant 4 is placed, and irradiate the planted plant 4 with light. The structure, installation location, color, number, wavelength, etc. of the lights 17 are not particularly limited, and are determined depending on the type of planted plant 4, its planting method, growth stage, etc. Furthermore, various equipment such as a water circulation device and a blower required depending on the planting environment are similarly appropriately selected and installed as necessary.

[0028] The plate body 2 is a plate-shaped light shielding plate that is attached to the planting shelf 15 via the mounting fixture 3. The board body 2 has a required width, height, and thickness, and is attached to a specified location of the planting shelf 15 (for example, a pillar above or to the side of the shading location) via a mounting fixture 3. This allows the board body 2 alone to block light from the lights 17 arranged on the planting shelf 15 by preventing it from leaking outward, and to illuminate the plant 4 by reflection. The dimensions (width, height, thickness) of the board body 2 are, for example, 30 cm wide, 18 cm high, and 5 mm thick. The size of the board body 2 is not particularly limited, and is appropriately selected and determined in consideration of factors such as the width and height of the planting shelf 15, the position and range of illumination of the light 17, the required shading range, and the material that constitutes the board body 2. In addition, taking into consideration the risk of falling from the fixture 3, the material and size are selected and determined so that the weight is the weight that can be withstood by the clamping force of the fixture 3 or less. As shown in Figures 1(a) and (b), one side of the board body 2 is a reflective surface 5 that reflects light, and the other side is a shading surface 6 that blocks light, and the reflective surface 5 is attached facing the inside of the planting shelf 15 (the side facing the planted plants 4) and the shading surface 6 is attached facing the outside of the planting shelf 15.

[0029] The reflecting surface 5 is formed on the plate body 2 and serves to reflect light. The reflective surface 5 is formed on one side of the board body 2 and functions to reflect light from a light 17 arranged on the planting shelf 15 inward toward the planted plants 4 without leaking the light outside the planting shelf 15. The light reflected by the reflective surface 5 may include light emitted from the lights 17 arranged on the planting shelf 15, light reflected from the surface of the planted plants 4, and light reflected from the shelves 16 and pillars that make up the planting shelf 15. The specific configuration of the reflective surface 5 may be a mirror capable of totally reflecting the irradiated light, a mirror-like surface that is polished to reflect light, or a material with high reflectivity, such as a metal with a mirror finish, a resin such as a colored plastic that has been subjected to a glossy finish, or a material whose surface is painted with a glossy paint. By adopting such a configuration, it is possible to sufficiently reflect the light of the light 17 to the planted plants 4, and even in places that cannot be irradiated directly from above, the light can be irradiated with the same amount of light as the light 17 by reflection from the reflective surface 5.

[0030] Furthermore, when the surface of the reflective surface 5 or the entire material is colored, it is possible to change the wavelength of the reflected light, since light is reflected and absorbed depending on the color used. For example, if the color is white, light is not absorbed, and the reflected light is the same as the incident light, but if red light, which promotes photosynthesis in plant growth, and blue light, which increases the size of leaves and fruits, are to be reflected, it is possible to process the reflective surface 5 with a color such as magenta, which absorbs green wavelengths, and reflect the red and blue wavelengths to the planted plants 4 while absorbing the green wavelengths of the incident light.

[0031] The light blocking surface 6 is formed on the plate body 2 and serves to block light. The shading surface 6 is formed on the surface opposite to the reflecting surface 5 described above, and is installed so as to block the light of the lights 17 arranged on the planting shelf 15 and prevent the light from leaking outside the planting shelf 15. The light to be blocked by the shading surface 6 includes, as with the reflective surface 5, light emitted from the lights 17 arranged on the planting shelf 15, light reflected on the surface of the planted plants 4, and light reflected from the shelves 16 and pillars that make up the planting shelf 15, as well as light that is not reflected by the reflective surface 5 and is transmitted due to the color scheme and constituent materials (particularly the white acrylic plate) of the reflective surface 5, and light that enters from the side of the reflective surface 5. In addition, external incident light such as sunlight and indoor lights is also blocked by not entering the planting shelf 15, thereby preventing changes to the light environment for the planted plants 4. Possible specific configurations for the shading surface 6 include, for example, using resin such as colored plastic with a matte finish, painting with a light-absorbing black color, or molding with a material with low light transmittance. In particular, by applying a matte finish or light-absorbing paint, it is possible to suppress reflection by the shading surface 6 of incident light from outside the planting shelf 15, such as sunlight or indoor lights.

[0032] The mounting fixture 3 is used to clamp the board body 2 and the planting shelf 15 and install the board body 2 on the planting shelf 15. The mounting fixture 3 is composed of a first clamping portion 10, a second clamping portion 11, and a bending portion 12 having a predetermined length, with the first clamping portion 10 at one end of the bending portion 12 and the second clamping portion 11 at the other end, so that the first clamping portion 10 clamps the board body 2 and the second clamping portion 11 clamps the planting shelf 15. At least one mounting fixture 3 is provided for one plate body 2. The number of such mounting fixtures 3 is appropriately determined in consideration of the weight of the plate body 2 relative to the clamping force of the first clamping unit 10 and the second clamping unit 11, the size of the plate body 2, etc. 1, while a predetermined portion (upper, side, etc.) of the plate body 2 is clamped by the first clamping portion 10, the second clamping portion 11 clamps the shelf board 16 or the pillar, and the bending portion 12 is moved and adjusted as desired so that the plate body 2 is positioned in the open side portion of the planting shelf 15, whereby the plate body 2 reflects the light within the planting shelf 15 inward and suppresses leakage to the outside. The specific structure of the mounting fixture 3 is not particularly limited as long as it can clamp the plate body 2 and the planting shelf 15, and a conventionally known technology such as a clip structure may be used.

[0033] The first clamping portion 10 clamps the plate body 2 . The first clamping portion 10 is connected to one end of the bent portion 12 and clamps a predetermined portion of the plate body 2. The size and shape of the first clamping part 10 are determined taking into consideration the thickness and weight of the plate body 2, but since it is necessary to have at least a clamping force sufficient to prevent the plate body 2 from easily falling off when clamped, a preferred embodiment is to use a flat clip with a wide contact area with the front and back surfaces of the plate body 2. In addition, in order to increase the clamping force of the first clamping part 10, it is also preferred to provide a non-slip treatment on the contact part with the plate body 2, such as providing a non-slip surface made of a resin material or the like. However, since it is possible to remove the plate body 2 from the fixture 3 by pulling it at the work location when watering the plant 4, a structure without a non-slip surface may be considered. The predetermined portion of the plate body 2 that is clamped by the first clamping portion 10 is a portion where the plate body 2 can be positioned and the clamped state can be stably maintained, and is appropriately determined in consideration of the number of fixtures 3 and the size of the plate body 2. For example, in an embodiment where two fixtures 3 are provided, an embodiment where the upper portion of the plate body 2 is clamped at equal intervals as shown in FIG.

[0034] The second clamping portion 11 clamps the planting shelf 15 . The second clamping portion 11 is connected to the other end of the bending portion 12 opposite the first clamping portion 10, and clamps a predetermined portion of the planting shelf 15, thereby positioning the board body 2 clamped by the first clamping portion 10. The specific structure of the second clamping part 11 is configured taking into consideration the weight of the entire plate body 2 and the mounting fixture 3, but it is necessary that the clamping force is at least sufficient to prevent the plate body 2 and the mounting fixture 3 from falling off even when the bent part 12 is moved while clamping the planting shelf 15. For this reason, it is preferable to use a flat clip with a wide contact area with the planting shelf 15 or a round clip that can also be used on the pillars supporting the shelf board 16. Also, in order to increase the clamping force of the second clamping part 11, it is preferable to provide an anti-slip treatment on the part that comes into contact with the planting shelf 15, such as providing an anti-slip surface made of a resin material or the like. The predetermined location of the planting shelf 15 that is clamped by the second clamping part 11 is a location where the clamped state can be stably maintained without the clamping part easily moving, and is appropriately determined in consideration of the number of fixtures 3, the shape of the second clamping part 11, the shape of the planting shelf 15, the position of the board body 2, etc. For example, as shown in Fig. 2, a location that does not interfere with work on the planted plant 4 is preferable, such as a side of another shelf board 16B that is above the shelf board 16A on which the planted plant 4 is placed, a side of the top board that is the topmost board of the planting shelf 15, or a pillar part that constitutes the planting shelf 15.

[0035] The bent portion is provided between the first clamping portion 10 and the second clamping portion 12. The bending portion 12 has a predetermined length and is equipped with a first clamping portion 10 at one end and a second clamping portion 11 at the other end, with multiple bending points including connection points between the first clamping portion 10 and the second clamping portion 11, and is capable of bending at a certain angle at the bending points. Although there is no particular limitation on the length or bending structure of the bending portion 12, it is preferable that the bending portion 12 has a predetermined overall length (about 3 to 10 cm) and has multiple bending points in the middle of the bending portion 12. For example, as shown in Fig. 2, a mode can be adopted in which bending points made of universal joints are provided at four places in total, one at each of the joint parts with the first clamping part 10 and the second clamping part 12 and two at the middle of the bending portion 12, and bending at each bending point makes it possible to freely adjust the inclination and position of the installation position of the plate body 2.

[0036] In the structure of the mounting fixture 3, a mode can be adopted in which the clamping portion of the second clamping part 11 is made smaller than that of the first clamping part 10. By adopting such a mode, even if a wide clamping surface cannot be obtained due to the shape of the planting shelf 15, it becomes possible for the second clamping part 11, which has a small shape, to clamp the planting shelf 15. In this embodiment, when providing the contact surface with the clamping portion with an anti-slip treatment, it is also preferable to provide the anti-slip treatment only to the second clamping portion 11. Since the degree of the clamping surface of the second clamping portion 11 varies depending on the shape of the planting shelf 15, providing the anti-slip treatment to increase the clamping force helps to prevent the planting shelf 15 from falling off, and the first clamping portion 10 has a structure that allows the board body 2 to be easily removed during work such as watering, making it possible to increase convenience without providing the anti-slip treatment.

[0037] When light is reflected by the reflecting surface 5 of the plate body 2 to the planted plant 4, it is assumed that the efficiency of irradiation to the planted plant 4 may be poor depending on the mounting position and angle of the plate body 2. Therefore, a structure in which the light reflection angle is adjusted by bending the plate body 2 as shown in FIG. 3(a) can be considered. A specific structure for bending the plate body 2 employs a mode in which bending members 7 are provided at predetermined positions of the plate body 2. The positions and number of bending members 7 are not particularly limited, but may be, for example, the position of the dividing line when the plate body 2 is divided into two parts, top and bottom (see FIG. 3(a)), or the position of the dividing line when the plate body 2 is divided into three parts, left and right (not shown). By adopting such an embodiment, it becomes possible to freely adjust the direction of reflected light directed into the planting shelf 15 simply by adjusting the angle of the board body 2 via the bending member 7, and even when working inside the planting shelf 15, it is easy to secure work space by bending part of the board body 2 upward without removing the board body 2.

[0038] When working on the planting shelf 15 on which the plate body 2 is arranged, the basic procedure is to flip up the plate body 2 to the front side to secure an open space, and then to enter the planting shelf 15 with hands or tools from the space to work. However, it is assumed that the flipped up plate body 2 prevents the worker from getting any closer, or that the flipped up plate body 2 acts as a blind and gets in the way. Therefore, as shown in FIG. 3(b), a mode in which the plate body 2 can be extended and retracted in a sliding manner is conceivable. A specific structure for making the plate body 2 a sliding type may be a structure in which a slide plate 9 having the same structure as the plate body 2 is provided, and the plate body 2 and the slide plate 9 can slide in one direction via a conventionally known slide member 8. In this case, a structure in which the slide plate 9 can be stopped at any slide position relative to the plate body 2 is more preferable. By adopting this configuration, the overall size of the plate body 2 can be adjusted and the light-blocking range can also be adjusted simply by sliding the slide plate 9. Furthermore, working space can be secured without removing or bending the plate body 2 itself, which also contributes to improving work efficiency.

[0039] The operation of the plant cultivation shading board 1 according to the present invention having the above-mentioned configuration will be described with reference to Figs. As shown in the figure, the board body 2 is provided with a reflecting surface 5 on the planted plant 4 side and a shading surface 6 on the back surface of the reflecting surface 5, and the upper end of the board body 2 is clamped by a first clamping part 10. In addition, a second clamping part 11 is clamped to the side part of a shelf board 16B, and a bending part 12 is bent so that the board body 2 is disposed in a position where light can be irradiated to the planted plant 4 and light can be blocked to the outside of the planting shelf 15. A planted plant 4 is placed on a shelf board 16A provided on the planting shelf 15, and a light 17 that irradiates light toward the planted plant 4 is provided on the bottom surface of the shelf board 16B. The light emitted from the light 17 illuminates the planted plants 4 and their surroundings while traveling outward from the planting shelf 15. In addition, a portion of the light is reflected outward from the planting shelf 15 via the surfaces of the leaves of the planted plants 4, the pillars of the planting shelf 15, the shelf boards 16, etc. Most of the light directed toward the outside of the planting shelf 15 is reflected inward (toward the planted plant 4) by the reflective surface 5 of the board body 2 held in the planting shelf 15, and is used as light for growing the planted plant 4. A portion of the light that passes through the reflective surface 5 is also reflected and absorbed by the shading surface 6, thereby preventing light from leaking outside the planting shelf 15.

[0040] Although the basic configuration and operation of the plant cultivation shading board 1 according to the present invention have been described above, the present invention is not limited to the above-described embodiment or the configuration shown in the drawings. For example, in forming the plate body 2, as shown in Fig. 1(c), a mode can be considered in which a reflecting plate 18 having a reflecting surface 5 and a light-shielding plate 19 having a light-shielding surface 6 are bonded together to form a single plate body 2 having a reflecting surface 5 and a light-shielding surface 6. In such a mode, the method for bonding the reflecting surface 5 and the light-shielding surface 6 can be any ordinary method such as double-sided tape or adhesive, and is not particularly limited. Also, a mode in which a plurality of planting shade plates 1 are arranged on both opposing sides of the planting shelf 15 to reduce gaps and form an air flow path via a ventilation system is conceivable. Furthermore, even if the planting shelf 15 is installed outdoors and plants 4 are planted using sunlight, it is possible to block the light reflected by the structure of the planting shelf 15 or installed objects, etc., and reflect the light inward while suppressing leakage to the outside of the planting shelf 15.

[0041] As described above, the planting shade plate 1 of the present invention has the excellent effect of being able to shade the reflected light of light irradiated onto the planted plants 4 within the planting shelf 15 by attaching the plate body 2 to the planting shelf 15, and also being able to reflect the reflected light inwardly by the reflective surface 5 by adjusting the angle of the plate body 2. [Industrial Applicability]

[0042] The present invention is capable of blocking light necessary for planting on a planting shelf without reflecting it toward residents or planters, and it is possible to grow plants not only in planting spaces of ordinary houses and plant factories, but also in busy passageways of commercial facilities and train stations without reflecting the light used for planting to the outside. Therefore, it is believed that the "shade panel for planting" according to the present invention has great industrial applicability. [Explanation of symbols]
