Description

Technical Field

[0001] The present invention relates to a light-shielding plate used for planting, and more specifically, to a light-shielding plate for planting that shields light irradiated from a planting light used in a planting shelf.

Background Art

[0002] Conventionally, as a method for cultivating crops, soil cultivation in which the farmland is plowed to grow crops has been common. In recent years, however, hydroponics in which a shelf is placed indoors as a cultivation space and crops are grown has attracted attention. In addition, for plant cultivation, "water, air, moisture, nutrients, and a predetermined temperature suitable for growth" are essential. However, when cultivating plants indoors, in order to create an environment equivalent to the external environment, an LED light, a blower, a water circulation device, etc. are installed at a predetermined location on the shelf and used as appropriate. However, if the LED light is constantly on indoors, there are problems such as the shelf becoming brighter than the indoor brightness depending on the installation location, or the light entering people's eyes and causing glare. In addition, in the case of an LED light with strong directivity, since the light distribution angle is narrow, it is difficult to illuminate the entire plant.

[0003] In order to solve the above problems, a technical proposal described in Japanese Patent Application Laid-Open No. 2014-183747 (Patent Document 1) has been proposed. Specifically, a technique of a multi-stage cultivation device capable of irradiating cultivated plants on a cultivation shelf by reflecting light using a light reflector has been proposed.

[0004] However, in the technical proposal described in Patent Document 1, although it is possible to reflect sunlight on the plant itself, there is a problem that it is not possible to reflect and shield the LED light irradiated from directly above the shelf.

[0005] The applicant, under the idea of whether it is possible to create a reflector that can reflect the light of the lights installed for plant cultivation on the cultivation shelf towards the plants and appropriately block the light going outside the shelf in the above-mentioned light-shielding plate, focused on the technology of the arm that can move while the plate body is clamped by the clip, and developed a light-shielding plate having an attachment part that can be clamped to the cultivation shelf and consisting of a reflecting surface that reflects light and a light-shielding surface that blocks light, and thus arrived at the proposal of the "light-shielding plate for planting" according to the present invention.

Summary of the Invention

Problems to be Solved by the Invention

[0007] In view of the above problems, an object of the present invention is to provide a light-shielding plate having a reflecting surface that reflects light, a light-shielding surface that blocks light, and an attachment part that can be clamped to a cultivation shelf.

Means for Solving the Problems

[0008] To solve the above problems, the present invention is a light-shielding plate attached to an indoor planting shelf, comprising a plate body having a required width, height, and thickness, and at least one or more fixtures for attaching the plate body to the planting shelf. The plate body consists of a reflecting surface on one side that reflects light and a light-shielding surface on the other side that blocks light. The fixture consists of a first clamping part that clamps the plate body, a second clamping part that clamps the planting shelf, and a bending part provided between the first clamping part and the second clamping part. By clamping the second clamping part at a predetermined location of the planting shelf so that the plate body is positioned at the open side portion of the planting shelf, means are adopted to reflect the light inside the planting shelf in the inward direction by the plate body and suppress leakage to the outside.

[0009] Further, the present invention adopts means in which the reflecting surface is mirror-shaped.

[0010] Furthermore, the present invention adopts means in which the reflecting surface is colored and has a gloss finish.

[0011] Moreover, the present invention adopts means in which the first clamping portion and / or the second clamping portion are subjected to anti-slip processing.

[0012] Furthermore, the present invention adopts means in which the light-shielding surface has a matte finish.

[0013] Moreover, the present invention adopts means in which the plate body is bent at a predetermined location.

[0014] And also, the present invention adopts means in which a slide plate having the same structure as the plate body is provided on the plate body.

Advantages of the Invention

[0015] According to the light-shielding plate for planting of the present invention, one surface of the plate body is formed as a reflecting surface that reflects light, and the other surface is formed as a light-shielding surface that shields light. Thus, it is possible to perform both reflection and light shielding with only one plate body, and by sandwiching the fixture on the planting shelf, it is possible to shield light at any location and irradiate the plants in the planting shelf with the reflected light, achieving excellent effects such as these.

[0016] Also, according to the light-shielding plate for planting of the present invention, since the reflecting surface is mirror-finished, it is possible to sufficiently reflect the light of the light for plant growth, and by reflection on the mirror surface, it is also possible to irradiate locations that cannot be irradiated directly from above with approximately the same amount of light as the amount of light of the light.

[0017] Furthermore, according to the light-shielding plate for planting of the present invention, since the reflecting surface is colored, it is possible to reflect and irradiate the plants with light corresponding to the color of the reflecting surface. Additionally, by applying a gloss finish to the reflecting surface, the reflectivity of the reflecting surface is increased compared to the unprocessed state, and it is possible to reflect the irradiation of light from the light on the surface of the reflecting surface and provide a sufficient amount of light to the plants.

[0018] Furthermore, according to the light-shielding plate for planting of the present invention, by applying an anti-slip process to the first clamping portion and / or the second clamping portion, it is possible to prevent the light-shielding plate for planting from falling off from the portion clamped by the mounting portion.

[0019] Furthermore, according to the light-shielding plate for planting of the present invention, by subjecting the light-shielding surface to a matte finish, it is possible to suppress the reflection of light irradiated from outside the planting shelf toward the light-shielding surface.

[0020] Furthermore, according to the light-shielding plate for planting of the present invention, by making the plate body bendable at a predetermined location, it is possible to direct the light reflected into the planting shelf in multiple directions and facilitate securing the working space during work.

[0021] And furthermore, according to the light-shielding plate for planting of the present invention, by providing a slide plate having the same structure as the plate body on the plate body, it becomes easy to adjust the light-shielding range.

Modes for Carrying Out the Invention

[0023] The light-shielding plate 1 for planting according to the present invention is attached to the planting shelf 15, and its greatest feature is to reflect the light of the light 17 provided in the planting shelf 15 into the planting shelf 15 while shielding the light from outside the planting shelf 15. Hereinafter, an embodiment of the light-shielding plate 1 for planting according to the present invention will be described with reference to the drawings.

[0024] Furthermore, the light-shielding plate 1 for planting according to the present invention is not particularly limited to the embodiments described below, and can be appropriately changed within the scope of the technical idea of the present invention, that is, within the scope of shapes, dimensions, materials, etc. that can exhibit the same operational effects.

[0025] FIG. 1 is an explanatory view showing an embodiment of the light-shielding plate 1 for planting according to the present invention. (a) shows a state in which the reflecting surface 5 of the plate body 2 faces the front, (b) shows a state in which the light-shielding surface 6 of the plate body 2 faces the front, and (c) shows a state in which the lower part of the plate body 2 faces the front. FIG. 2 is an explanatory view showing a usage mode of the light-shielding plate 1 for planting according to the present invention. FIG. 3 is an explanatory view showing another embodiment of the light-shielding plate 1 for planting according to the present invention. (a) shows an embodiment in which a bending member 7 is provided at a predetermined location of the plate body 2, and (b) shows an embodiment in which a slide member 8 and a slide plate 9 are provided on the light-shielding surface 6 of the plate body 2. The light-shielding plate 1 for planting according to the present invention mainly comprises a plate body 2 and a fixture 3, and is attached to a planting shelf 15. Note that the "planting" described in the present text is an abbreviation for plant cultivation. Also, the "light" described in the present text refers to a light source for planting including an LED light and an incandescent lamp.

[0026] The planting shelf 15 mainly refers to a shelf used for indoor planting. For the main configuration of the planting shelf 15, a conventionally known shelf structure can be used, and there is no particular limitation. Also, the planting shelf 15 is provided with one or a plurality of shelf boards 16, and pots or containers in which plants to be cultivated (hereinafter referred to as "planted plants 4") are planted are installed on the top surface of the shelf board 16. Therefore, regarding the length and width of the shelf board 16, the height between the shelf boards 16 (the height of the planting space), and the size of the planting shelf 15 that houses the shelf board 16, they will be appropriately selected according to the type and size of the planted plant 4.

[0027] Also, as shown in FIG. 2, in order to supply the light necessary for the planted plant 4, a light 17 is disposed at a predetermined position (mainly the bottom surface portion) of another shelf board 16B corresponding to the upper stage of the shelf board 16A on which the planted plant 4 is installed, and will irradiate toward the planted plant 4. Regarding the structure, arrangement position, color, number, wavelength, etc. of the light 17, there is no particular limitation, and it is determined according to the type of the planted plant 4, its planting method, growth stage, etc. Further, similarly, regarding various facilities such as a water circulation device and a blower required by the planting environment, they will be appropriately selected and installed as needed.

[0028] The plate body 2 is a plate-shaped light-shielding plate attached to the planting shelf 15 via the fixture 3. The plate body 2 has a required width, height, and thickness, and is attached to a predetermined position of the planting shelf 15 (for example, a column above or on the side of the light-shielding portion) via the fixture 3. Thereby, only the plate body 2 can suppress the leakage of the light of the light 17 disposed on the planting shelf 15 to the outside and enable the irradiation of the planted plant 4 by reflection. For the size (width, height, thickness) of the plate body 2, for example, a plate body having a width of 30 cm, a height of 18 cm, and a thickness of 5 mm is used. The size of such a plate body 2 is not particularly limited, and it is appropriately selected and determined in consideration of elements such as the width and height of the planting shelf 15, the irradiation position and range of the light 17, the required light-shielding range, etc., and the material constituting the plate body 2. In addition, in consideration of the risk of falling from the fixture 3, the material and size are selected and determined so as to have the following weight that can withstand the clamping force by the fixture 3. As shown in FIGS. 1(a) and (b), one surface of the plate body 2 is a reflecting surface 5 that reflects light, and the other surface is a light-shielding surface 6 that shields light, and the reflecting surface 5 is attached toward the inside of the planting shelf 15 (the planted plant 4 side), and the light-shielding surface 6 is attached toward the outside of the planting shelf 15.

[0029] The reflecting surface 5 is formed on the plate body 2 and reflects light. The reflecting surface 5 is formed on one surface of the plate body 2, and functions to reflect the light of the light 17 disposed on the planting shelf 15 inwardly toward the planted plants 4 without leaking the light outside the planting shelf 15. As the light to be reflected by the reflecting surface 5, in addition to the light emitted from the light 17 disposed on the planting shelf 15, the light reflected on the surface of the planted plants 4 and the light reflected from the shelf board 16, pillars, etc. constituting the planting shelf 15 can be considered. Regarding the specific configuration of the reflecting surface 5, a mirror capable of total reflection of the irradiated light, a mirror surface forming polished so that the surface for reflecting light becomes mirror-like, or a mode of using a material with high reflectivity can be considered. For example, various metals with mirror finishes can be used, resins such as colored plastics with gloss processing can be used, or a mode of coating the surface of various materials with gloss paint can be considered. By adopting such a mode, it is possible to sufficiently reflect the light of the light 17 to the planted plants 4, and also to irradiate the locations where irradiation cannot be performed directly from above with a light amount comparable to the light amount of the light 17 by reflection on the reflecting surface 5.

[0030] Also, when coloring the surface or the entire material of the reflecting surface 5, since light reflection and absorption are performed depending on the color used, it is possible to change the wavelength of the light to be reflected. For example, if it is white, no light absorption occurs, so it becomes the same reflected light as the incident light. However, when reflecting the red light that promotes photosynthesis and the blue light that enlarges leaves and fruits during plant growth, the reflecting surface 5 can be processed with a magenta color that absorbs the green wavelength, etc., and while absorbing the green wavelength of the incident light, reflect the red and blue wavelengths to the planted plants 4.

[0031] The light-shielding surface 6 is formed on the plate body 2 and shields light. The light-shielding surface 6 is formed on the surface opposite to the above-described reflecting surface 5, shields the light of the light 17 disposed on the planting shelf 15, and is installed so as not to leak outside the planting shelf 15. As the light to be blocked by the light-blocking surface 6, similar to the reflecting surface 5, in addition to the light emitted from the light 17 disposed on the planting shelf 15, the light reflected on the surface of the planted plant 4, and the light reflected from the shelf board 16 and columns constituting the planting shelf 15, the light that has passed through without being reflected by a part of the reflecting surface 5 due to the color scheme and constituent materials (especially white acrylic plate) of the reflecting surface 5, and the light incident from the side surface portion of the reflecting surface 5 are also blocked. Also, with respect to incident light from the outside such as sunlight and indoor lighting, it is blocked without entering into the planting shelf 15, thereby preventing changes in the light environment for the planted plant 4. Regarding the specific configuration of the light-blocking surface 6, for example, it is conceivable to use a resin such as a colored plastic with a matte finish, paint it with a black-based paint that absorbs light, or form it with a material having low light transmittance. In particular, by applying a matte finish or light-absorbing paint, it is possible to suppress the reflection of the incident light from the outside of the planting shelf 15 such as sunlight and indoor lighting by the light-blocking surface 6.

[0032] The fixture 3 is for sandwiching the plate body 2 and the planting shelf 15 and installing the plate body 2 on the planting shelf 15. The fixture 3 is composed of a first clamping portion 10, a second clamping portion 11, and a bent portion 12 having a predetermined length. The first clamping portion 10 is provided at one end of the bent portion 12, and the second clamping portion 11 is provided at the other end. The plate body 2 is clamped by the first clamping portion 10, and the planting shelf 15 is clamped by the second clamping portion 11. At least one or more fixtures 3 are provided for one plate body 2. The number of such fixtures 3 is appropriately determined in consideration of the weight of the plate body 2 with respect to the clamping force of the first clamping portion 10 and the second clamping portion 11, the size of the plate body 2, and the like. As shown in FIG. 1, while clamping a predetermined portion (such as the upper side or the side) of the plate body 2 with the first clamping portion 10, and with the second clamping portion 11 clamping the shelf board 16 or the column, by arbitrarily moving and adjusting the bent portion 12 so that the plate body 2 is positioned at the open side portion of the planting shelf 15, the plate body 2 reflects the light inside the planting shelf 15 inward and suppresses the leakage to the outside. Also, regarding the specific structure of the fixture 3, there is no particular limitation as long as it can clamp the plate body 2 and the planting shelf 15, and a conventionally known technique such as a clip structure may be used.

[0033] The first clamping part 10 clamps the plate body 2. The first clamping part 10 is connected to one end of the bending part 12 and clamps a predetermined position of the plate body 2. The size and shape of the first clamping part 10 are configured in consideration of the thickness and weight of the plate body 2. However, since it is necessary to have a clamping force that does not easily drop off at least when the plate body 2 is clamped, it is desirable to use a flat clip with a wide contact area with the front and back surfaces of the plate body 2. Also, in order to increase the clamping force of the first clamping part 10, it is also preferable to apply an anti-slip process to the contact part with the plate body 2, such as providing an anti-slip made of a resin material or the like. However, during operations such as watering the planted plant 4, since it is also possible to consider a mode of removing the plate body 2 at the work location by pulling it from the fixture 3, a structure that does not have an anti-slip is also conceivable. In addition, the predetermined position of the plate body 2 clamped by the first clamping part 10 is a position where the clamping state can be stably maintained while positioning the plate body 2, and is appropriately determined in consideration of the number of fixtures 3, the size of the plate body 2, etc. For example, in the mode with two fixtures 3, as shown in FIG. 2, a mode of clamping the upper part of the plate body 2 at equal intervals can be considered.

[0034] The second clamping part 11 clamps the planting shelf 15. The second clamping part 11 is connected to the other end of the bending part 12 on the side opposite to the first clamping part 10, and positions the plate body 2 clamped by the first clamping part 10 by clamping a predetermined position of the planting shelf 15. Regarding the specific structure of the second clamping part 11, it is configured in consideration of the weight of the entire plate body 2 and the fixture 3. However, it is necessary to have a clamping force such that the plate body 2 and the fixture 3 do not drop off even when the bending part 12 is moved at least when the planting shelf 15 is clamped. Therefore, it is desirable to use a flat clip with a wide contact area with the planting shelf 15, a round clip that can also be used for the pillar supporting the shelf board 16, etc. Also, in order to increase the clamping force of the second clamping part 11, it is also preferable to apply an anti-slip process to the contact part with the planting shelf 15, such as providing an anti-slip made of a resin material or the like. The predetermined position of the planting shelf 15 held by the second holding part 11 is a position where the holding state can be stably maintained without the holding part easily wandering, and is appropriately determined in consideration of the number of the fixtures 3, the shape of the second holding part 11, the shape of the planting shelf 15, the position of the plate body 2, etc. For example, as shown in FIG. 2, the side of another shelf board 16B corresponding to the upper stage of the shelf board 16A on which the planted plant 4 is installed, the side of the top board corresponding to the uppermost stage of the planting shelf 15, the column part constituting the planting shelf 15, etc., are suitable positions that are not likely to impede the work on the planted plant 4.

[0035] The bent part is provided between the first holding part 10 and the second holding part 12. The bent part 12 has a predetermined length and is provided with the first holding part 10 at one end and the second holding part 11 at the other end, and a plurality of bent portions including the connection points with the first holding part 10 and the second holding part 11 are provided, and bending at a certain angle is possible at the bent portions. There is no particular limitation on the length and the bent structure of the bent part 12, but it is preferable to have a plurality of bent portions in the middle of the bent part 12 having a predetermined overall length (about 3 to 10 cm). For example, as shown in FIG. 2, one at each joint part between the first holding part 10 and the second holding part 12 and two in the middle of the bent part 12, a total of four, a mode with bent portions composed of universal joints can be adopted, and by bending at each bent portion, the inclination adjustment and position adjustment at the installation position of the plate body 2 can be freely performed.

[0036] In the structure of the fixture 3, a mode of making the holding part of the second holding part 11 smaller than the first holding part 10 can be adopted. By adopting such a mode, even when a wide holding surface cannot be obtained due to the shape of the planting shelf 15, it is possible to hold the planting shelf 15 with the second holding part 11 having a small shape. In such a mode, when providing an anti-slip process on the contact surface with the clamping portion, a mode of performing the anti-slip process only on the second clamping portion 11 is also preferable. Since the degree of the clamping surface of the second clamping portion 11 varies depending on the shape of the planting shelf 15, applying the anti-slip process to increase the clamping force contributes to preventing the plant from falling off. Meanwhile, for the first clamping portion 10, since the plate body 2 is easily removed during operations such as watering, the convenience can be enhanced without applying the anti-slip process.

[0037] When the plate body 2 reflects light onto the planted plant 4 by the reflecting surface 5, it is assumed that the irradiation efficiency on the planted plant 4 may be poor depending on the mounting position and angle of the plate body 2. Therefore, as shown in Fig. 3(a), a structure for adjusting the reflection angle of light can be considered by bending the plate body 2. As a specific structure for bending the plate body 2, a mode of providing a bending member 7 at a predetermined position of the plate body 2 is adopted. Note that the position and number of the bending members 7 provided are not particularly limited. For example, the dividing line position when the plate body 2 is divided into two parts vertically (see Fig. 3(a)) or the dividing line position when the plate body 2 is divided into three parts horizontally (not shown) can be considered. By adopting such a mode, it is possible to freely adjust the direction of the reflected light directed into the planting shelf 15 only by adjusting the angle of the plate body 2 via the bending member 7. Also, during the operation inside the planting shelf 15, it becomes easy to secure a working space by bending a part of the plate body 2 upward without removing the plate body 2.

[0038] When working on the planting shelf 15 where the plate body 2 is arranged, the basic operation is to flip the plate body 2 upward to the front side to secure an open space, and then insert the hand or tools into the planting shelf 15 from this space to perform the work. However, it is assumed that the operator cannot get closer due to the flipped-up plate body 2, or the flipped-up plate body 2 may block the line of sight and cause interference. Therefore, as shown in Fig. 3(b), a mode in which the plate body 2 can be telescopically extended and retracted in a sliding manner can be considered. For the specific structure for making the plate body 2 slide, a slide plate 9 having the same structure as the plate body 2 can be provided, and the plate body 2 and the slide plate 9 can be made slidable in one direction via a conventionally known slide member 8. At this time, a structure in which the slide plate 9 can be stopped at an arbitrary slide position with respect to the plate body 2 is more preferable. By adopting such a mode, by simply sliding the slide plate 9, the size of the entire plate body 2 can be adjusted, and the light-shielding range can also be adjusted. Furthermore, a working space can be secured without removing or bending the plate body 2 itself, which also contributes to improving the working efficiency.

[0039] Regarding the light-shielding plate 1 for planting according to the present invention having the above-described structural mode, its operation will be described based on Figs. 1 and 2. As shown in the figure, on the plate body 2, a reflecting surface 5 is provided on the side of the planted plant 4, and a light-shielding surface 6 is provided on the back surface of the reflecting surface 5. The upper end portion of the plate body 2 is clamped by a first clamping portion 10. Further, the second clamping portion 11 is clamped to the side surface portion of the shelf board 16B, and the bending portion 12 is bent so that the plate body 2 is arranged at a position where it is possible to irradiate the planted plant 4 and shield light outside the planting shelf 15. Then, the planted plant 4 is arranged on the shelf board 16A provided on the planting shelf 15, and a light 17 for irradiating the planted plant 4 is provided on the bottom surface portion of the shelf board 16B. The light irradiated from the light 17 illuminates the planted plant 4 and its surroundings while traveling outward of the planting shelf 15. Also, a part of the light is reflected outward of the planting shelf 15 through the surface of the leaves of the planted plant 4, the columns of the planting shelf 15, the shelf board 16, etc. The light directed towards the outside of the planting shed 15 is mostly reflected in the inward direction (towards the planted plants 4 side) by the reflecting surface 5 of the plate body 2 sandwiched by the planting shed 15 and is utilized as light for growing the planted plants 4. And a part of the light transmitted through the reflecting surface 5 is also reflected and absorbed by the light-shielding surface 6, thereby suppressing the leakage of light to the outside of the planting shed 15.

[0040] As described above, the basic configuration and operation of the light-shielding plate 1 for planting according to the present invention have been described. However, the present invention is not limited to the configurations shown in the above embodiments and drawings. For example, when configuring the plate body 2, as shown in Fig. 1(c), a mode of forming a single plate body 2 having a reflecting surface 5 and a light-shielding surface 6 by adhering a reflecting plate 18 having a reflecting surface 5 and a light-shielding plate 19 having a light-shielding surface 6 can also be considered. Regarding the method of adhering the reflecting surface 5 and the light-shielding surface 6 in such a mode, conventional means such as double-sided tape or adhesive can be adopted and there is no particular limitation. Also, a mode can be considered in which a plurality of light-shielding plates 1 for planting are arranged on both opposing side surfaces of the planting shed 15 with a reduced gap to form an air flow path through a ventilation facility. Furthermore, even in a mode where the planting shed 15 is installed outdoors and the planted plants 4 are planted with sunlight, it is possible to shield the reflected light reflected by the structure and installed objects of the planting shed 15, suppress the leakage to the outside of the planting shed 15, and reflect it in the inward direction.

[0041] As described above, according to the light-shielding plate 1 for planting according to the present invention, by attaching the plate body 2 to the planting shed 15, it is possible to shield the reflected light of the light irradiated to the planted plants 4 in the planting shed 15, and by adjusting the angle of the plate body 2, it is also possible to reflect the reflected light in the inward direction by the reflecting surface 5, and thus excellent effects are achieved.

Industrial Applicability

[0042] When planting in a planting shelf, the present invention can block light without reflecting it towards residents, planting workers, etc. It is possible to grow plants without reflecting the light used for planting to the outside not only in planting spaces such as ordinary houses and plant factories, but also in passages with a lot of pedestrian traffic such as commercial facilities and inside stations. Therefore, it is considered that the industrial applicability of the "light-shielding plate for planting" according to the present invention is great.
