Abstract
Description
Technical Field
[0001] The present invention relates to an improvement of gardening supplies, and more specifically, to a planter box that can be neatly arranged regardless of the type and shape of plants, and can also maintain an even growth environment for plants.
Background Art
[0002] In recent years, gardening activities such as gardening and home vegetable gardens have become popular even in urban areas, and the demand for simple planters that can effectively utilize limited space to grow plants has been increasing. Since they are easy to use even on balconies and small plots of land, box-shaped planter boxes that can grow multiple plants together are known (for example, see Patent Document 1).
[0003] In such a planter box, flowerpots made of hard containers such as pottery or plastic are accommodated. Since these flowerpots maintain a predetermined shape and can stand independently individually, they are also suitable for single use.
[0004] However, when multiple hard flowerpots are accommodated in the same planter box, variations are likely to occur in the height of each pot and the depth of the soil depending on the type of plant, and the levels of the upper surface of the soil and the upper end of the pot become uneven. Therefore, there is a risk that the visual balance will deteriorate, or the sunlight conditions will become uneven and the growth of plants will also become uneven.
[0005] In addition, since the shape of the hard flowerpot is fixed, dead space in the planter box is likely to occur during storage, and there is also a risk that operations such as replanting and cleaning will become difficult.

Summary of the Invention
[0007] This invention was made in view of the problems with conventional gardening supplies as described above, and its purpose is to provide a planter box that allows for the neat arrangement of plants regardless of their type or shape, and that can also maintain a uniform growing environment for the plants. [Means for solving the problem]
[0008] The means employed by the present inventor to solve the above technical problems will be described below with reference to the attached drawings.
[0009] In other words, the present invention is a planter box comprising a plant storage bag 1 made of a flexible material with a foldable upper end, and a box-shaped box body 2 capable of accommodating multiple plant storage bags 1, Multiple support plates 3, whose height can be individually adjusted, are provided inside the box body 2, so that the plant storage bags 1 can be placed on each of the support plates 3. The planter box was completed by employing a technical means that allows the upper surface level of the soil S in each plant storage bag 1 to be arranged at approximately the same height by adjusting the position of the support plate 3 and the position of the folded portion 11 formed at the upper end of the plant storage bag 1.
[0010] Furthermore, in order to solve the above problems, the present invention may also employ, if necessary, a technical means of forming multiple support sections 22 on the opposing side walls 21 of the box body 2 to support the end of the support plate 3 and enable its installation.
[0011] Furthermore, in order to solve the above problems, the present invention may also employ, if necessary, a technical means of forming a hole 22A in the support portion 22 of the box body 2, so that the end of the support plate 3 can be inserted into the hole 22A and installed.
[0012] Furthermore, in order to solve the above problems, the present invention may also employ, if necessary, the technical means of forming a handle portion 12 on the side of the plant storage bag 1, in addition to the above means.
[0013] Furthermore, in order to solve the above problems, the present invention may also employ, if necessary, a technical means of forming the plant containment bag 1 from a porous nonwoven fabric that has breathability and drainage properties, in addition to the above means.
[0014] Furthermore, in order to solve the above problems, the present invention may also employ, if necessary, a technical means of configuring the box body 2 so that the fence 4 can be fixed upright. [Effects of the Invention]
[0015] According to the present invention, by constructing a planter box by combining plant storage bags made of a flexible material with height-adjustable support plates, even if the amount and shape of soil differ in each bag, the top surface level of the soil in each plant storage bag can be arranged to be approximately the same height. This results in an aesthetically pleasing and orderly appearance, improving the scenic value of the gardening space, and making it easier to maintain uniform sunlight and watering conditions for all plants, thus contributing to the healthy growth of plants.
[0016] Furthermore, by forming the plant storage bags from a flexible material, the bags can be flexibly positioned according to the shape of the space inside the planter box, thereby increasing storage efficiency and minimizing dead space. In addition, if necessary, handles can be added to the sides of the plant storage bags, making it easier to insert and remove the bags and to perform transplanting work, thus improving the user's work efficiency.
[0017] Furthermore, by configuring the support plate to be supported by engaging with or inserting it into the support portion of the box body, the support height can be changed without using tools, making it easy to adjust the height of the plant storage bag.
[0018] In addition, the fence can be fixed to the box body so that it can stand up, which can obtain a visual shielding effect, and the lower end of the fence is stably supported by the weight of the planter box, and it is also possible to prevent it from falling due to wind or the like.

Modes for Carrying Out the Invention
[0020] An embodiment of the present invention will be described based on FIGS. 1 to 6. In the figures, what is indicated by reference numeral 1 is a plant accommodation bag, what is indicated by reference numeral 2 is a box body, what is indicated by reference numeral 3 is a support plate, and what is indicated by reference numeral 4 is a fence.
[0021] The present invention is a planter box composed of a plant accommodation bag 1 made of a flexible material and having an upper end portion that can be folded back, and a box-shaped box body 2 that can accommodate a plurality of the plant accommodation bags 1 (see FIG. 1).
[0022] As the material for the plant containment bag 1, for example, a polypropylene or polyester nonwoven fabric formed by the spunbond method or needle punch method can be used, thereby obtaining a porous structure with excellent breathability and drainage. Alternatively, woven or knitted fabrics made of natural or synthetic fibers, or flexible film-like sheet materials can also be used.
[0023] Furthermore, it is preferable that the plant containment bag 1 be cylindrical or polygonal prism-shaped, with a structure that allows the upper end to be folded outward, and that drainage holes for proper drainage be provided at predetermined positions at the bottom of the bag. In this embodiment, a handle portion 12 for easy movement and removal can be formed integrally or separately on the side of the bag body (see Figure 2).
[0024] Next, multiple support plates 3, whose height can be individually adjusted, are placed inside the box body 2, so that the plant storage bags 1 can be placed on each of the support plates 3.
[0025] The box body 2 is a box-shaped member capable of housing multiple plant storage bags 1 together, and can employ a rectangular frame structure formed by connecting multiple rod-shaped members in a frame-like manner. This frame can function as a floor surface on which each plant storage bag 1 is placed by installing multiple support plates 3 between opposing side frames. Alternatively, the box body 2 may be a roughly box-shaped structure consisting of a bottom plate and side plates.
[0026] For the box body 2, materials such as ASA resin (acrylic styrene acrylonitrile), rigid polyvinyl chloride (PVC), and weather-resistant polystyrene can be used to ensure weather resistance for outdoor use. Furthermore, using natural materials such as wood or bamboo can enhance the aesthetic and decorative value. In this case, it is preferable to apply anti-corrosion treatment, water-repellent treatment, or UV-protective treatment to the surface of these materials.
[0027] Furthermore, the support plate 3 is made of a lightweight yet sufficiently rigid plate material, and can be made of synthetic resin, metal, plywood, or the like. In addition, through holes or slits can be provided on the surface of the support plate 3 to improve ventilation and drainage.
[0028] Furthermore, multiple support sections 22 are formed on the opposing side walls 21 of the box body 2 to support the ends of the support plate 3 and allow it to be erected (see Figure 3).
[0029] More specifically, a hole 22A is formed in the support portion 22 of the box body 2, and the end of the support plate 3 can be inserted through the hole 22A for installation. This makes it possible to change the support height without using tools, and to easily adjust the height of the plant storage bag 1.
[0030] Other support structures include forming shelf-like steps or recesses in the side wall to support the edge of the support plate 3, or using brackets or fittings to secure it in a height-adjustable manner.
[0031] With the above configuration, the user can adjust the position of the support plate 3 and the folded portion 11 formed at the upper end of the plant storage bag 1 to arrange the upper surface level of the soil S in each plant storage bag 1 to approximately the same height, according to the amount of soil S placed in the plant storage bag 1 and the size of the plants (see Figures 4 and 5).
[0032] Furthermore, in this embodiment, as shown in Figure 6, a fence 4 that serves as a screen or partition can be erected and fixed to the box body 2 as needed. This fence 4 consists of a lightweight resin or metal grid or plate and may have a decorative shape at the upper end.
[0033] A support post is provided at the lower end of the fence 4, and the fence 4 can be fixed in an upright position by inserting this support post into an insertion hole provided in the upper edge or internal structure of the box body 2. This insertion hole is formed, for example, near the four corners of the box body 2 and is shaped to correspond to the cross-sectional shape of the support post, thereby creating appropriate frictional resistance during insertion and achieving a self-supporting fit. Furthermore, to further enhance stability, the lower end of the support post may be fixed to the box body 2 or made to allow for deeper insertion. In this way, the fence 4 can be easily and reliably installed without the use of tools.
[0034] Although the present invention is generally configured as described above, the present invention is by no means limited to the illustrated embodiment, and various modifications are possible within the scope of the claims. For example, the support structure of the support plate 3 is not limited to the insertion method into the hole 22A described above, but may also be configured such that a plurality of shelf support members (rail-shaped members) are provided along the inner surface of the box body 2, and the support plate 3 is slidably mounted along these shelf support members.
[0035] Alternatively, a configuration may be adopted in which multiple small holes are provided in the side wall of the box body 2, and the support plate 3 is supported by pins inserted into these holes. Furthermore, a configuration may be adopted in which a protrusion is formed on the inner wall surface of the box body 2, and the support plate 3 is supported by being placed directly on the desired protrusion, thereby reducing the number of parts, simplifying manufacturing, and lowering costs.
