Description

A PLANT HOUSING DEVICE
FIELD OF INVENTION
The invention relates to a plant housing device suitable for landscaping, and in particular, to a plant housing device suitable for use in vertical landscaping.
BACKGROUND TO THE INVENTION
The following discussion of the background to the invention is intended to facilitate an understanding of the present invention. However, it should be appreciated that the discussion is not an acknowledgment or admission that any of the material referred to was published, known or part of the common general knowledge in any jurisdiction as at the priority date of the application.
Urban heat island effect (UHIE) refers to the phenomenon when city
temperatures run higher than those in suburban and rural areas. UHIE occurs primarily due to the growing numbers of buildings being built as a consequence of urbanization and economic growth, and these growing numbers of buildings have supplanted vegetation and trees previously filling the city area. In addition, human activities generate heat and such generation of heat contributes to the rise in city temperatures.
In an attempt to reduce the adverse influence of the UHIE, vegetation is grown on rooftops (i.e. green roof), and more recently on building facades (i.e. green wall), to compensate for the loss of supplanted vegetation and trees. The vegetation serves to filter greenhouse gases such as carbon dioxide and other toxins in the city. It has been studied and demonstrated that such vegetation helps to reduce the building ambient temperature, resulting in lesser dependence on electrical appliances such as fans, air-conditioning units, etc, thereby lessening the building's energy consumption.
In a conventional green wall system, plant substrates (including the soil, pebbles etc whereby the roots of the plants may anchor onto) are conveniently contained in big geotextile bags. Each geotextile bag is packed into a modular plant housing device having a rectangular or square box shape. The modular plant housing devices are then assembled and stacked up in a vertical manner to form a vertical wall. Plant root balls are planted in the plant substrates and when plant growth has established, the vertical wall is said to be covered with vegetation, thereby forming a green wall. As time passes, settling and disintegrating of plant substrates due to
containment within a big geotextile bag becomes apparent since the modular plant housing devices are assembled vertically. When settling of the plant substrates occur, the root balls of the plants may lose grip on the plant substrates. This affects the optimal growth of the plants, especially those positioned at higher level in the plant housing devices. Topping up of the plant substrates may be needed and this adds to the weight of the entire assembly. This in turn may pose as a hazard particularly when the assembly is to be mounted onto a building facade.
Further, during irrigation water flows from top plant housing devices to bottom plant housing devices. Excess water may carry leached fertilizers and may accumulate in the bottom plant housing devices. Such accumulation of fertilizers in the plant substrates leads to problems such as salt burn effects in the plants, thereby affecting the optimal growth of the plants.
In the event that certain sections of the plant housing device require
replacement, for instance, when the plants affected by the salt burn effects (which are usually located nearer the bottom of the plant housing device) need to be replaced, the entire geotextile bag will have to be removed from the assembly and plant substrates repacked.
Therefore, it is desirable to provide plant housing device that overcomes, or at least alleviates, the above problems. SUMMARY OF THE INVENTION
Throughout this document, unless otherwise indicated to the contrary, the terms "comprising", "consisting of, and the like, are to be construed as non-exhaustive, or in other words, as meaning "including, but not limited to".
In a first aspect of the present invention, there is provided a plant housing device for use in landscaping, comprising: - a substrate container having a plurality of compartments for containing a plurality of plant substrates, wherein the substrate container is formed of a substantially grid configuration thereby forming the plurality of
compartments; and - a casing defining a hollow body therein to house the substrate container, the casing having a plurality of openings corresponding to the plurality of compartments for access to the plurality of plant substrates.

DETAILED DESCRIPTION
The invention relates to a plant housing device suitable for landscaping, and in particular, to a plant housing device suitable for use in vertical landscaping.
A first embodiment of the invention is illustrated in FIG. 1 , showing an exploded view of the plant housing device 1, and FIG. 2, showing an assembled plant housing device 1. The plant housing device 1 comprises a substrate container 2 having a plurality of compartments 3 for containing a plurality of plant substrates (not shown) and a casing 6 (alternatively, 6a and 6b) defining a hollow body therein to house the substrate container 2. Each plant substrate is contained in individual geotextile bag, and therefore the plurality of plant substrates are contained in a plurality of geotextile bags.
In the embodiment as illustrated, the substrate container 2 comprises three horizontal grid members 4 and three vertical grid members 5 to form a grid configuration, thereby forming a total of sixteen compartments 3. Although a sixteen-compartment substrate container 2 has been described herein, it is understood and appreciated that the number of horizontal grid members 4 and the number of vertical grid members 5 may be varied in order to obtain the desired number of compartments. Further, the size of each compartment 3 may be adjusted by varying the distance between each horizontal grid member 4 and each vertical grid member 5. For example, if different species of plants are intended to be placed in the same plant housing device, and if some of these plant substrates require more space than the others in order to develop optimal plant growth, then differently sized compartments 3 in the substrate container 2 may be designed and catered for.
The casing 6 is shown to comprise a back cover 6a and a front cover 6b. The back cover 6a is shown to comprise two opposing side walls connected by a back wall, thereby forming an "U" shape when viewed from the plan view. In this illustration, the front cover 6b is the side of the casing 6 which provides access to the plant substrates. The front cover 6b contains openings 7 corresponding to the compartments 3, through which the plant substrates may be assessed. The casing 6 is formed and defines a hollow body within the casing 6 when the back cover 6a and front cover 6b are joined together in a closed manner. The hollow body houses the substrate container 2 within the hollow body. Within the hollow body defined by the interior of the casing 6, horizontal support members 8 and vertical support members 9 are provided on the interior of the back cover 6a to hold in place the horizontal grid members 4 and the vertical grid members 5, respectively. The horizontal support members 8 and vertical support members 9 are preferably configured to have gripping or clipping action on the horizontal grid members 4 and the vertical grid members 5, respectively, to thereby securing them in place. As illustrated in FIG. 3f, one end of the horizontal support members 8 (similarly for the vertical support members 9) is tapered to guide the installation of the horizontal grid member 4. As illustrated in FIG. 3d, the horizontal support members 8 provided on the back wall of the back cover 6a are angled and positioned to hold the substrate container 2 such that the substrate container 2 sits snugly and the substrates in the geotextile bags sit snugly by gravity within the hollow body when the casing 6 is closed. This arrangement of the horizontal support members 8 minimises the sagging of the horizontal grid members 4 when the substrate container is eventually filled with geotextile bags. In this manner, the plant substrates, when housed in the substrate container 2, are secured and will not fall out of position. To further secure the geotextile bags in place, the horizontal grid members 4 and vertical grid members 5 are preferably each provided with protrusions 40, 42 to enhance the grip on the geotextile bags. The horizontal grid members 4 and the vertical grid members 5 are preferably each perforated to allow the growth of the root balls of the plant substrates and penetration of water via the perforations 44, 46. The horizontal grid members 4 and the vertical grid members 5 having protrusions 40, 42 and perforations 44, 46 are shown in FIG. 3c. Additionally, front plates 50 may be slidably inserted into the front cover 6b to prevent the geotextile bags from falling out of the plant housing device 1. FIG. 3e shows front, side and perspective views of the plant housing device 1 with the front plates 50 inserted into or removed from the front cover 6b. A flange 64 may be provided at one end of the front plate 50 for easy gripping and sliding motion. In an attempt to prevent the front plate 50 from falling out of the plant housing device 1, a groove 66 may be provided on the front plate 50 and a catch (not shown) is provided on the front cover 6b to catch the groove, thereby holding the front plate securely in place. It is to be understood that the height of the front plates 50 is sufficiently tall to prevent the geotextile bags from toppling out of the openings 7. Preferably, the height of the front plates 50 is at least the height of the centre of gravity of the geotextile bags. It is illustrated in this embodiment that the back cover 6a is wider than the front cover 6b in order to accommodate the horizontal support members 8 and vertical support members 9. It may be the case where the horizontal support members 8 and vertical support members 9 are located on the interior of the front cover 6b instead. Besides providing openings 7 on the front cover 6b, further openings 7 may also be provided on the back cover 6a such that the plant housing device 1 is symmetrical on both the front end and back end, i.e. access to the plant substrates is available through both the front end and the back end. This arrangement is useful as a partition wall. The plant housing device 1 further comprises an irrigation means 10 located at the top of the plant housing device 1, as shown in FIGS. 1, 2, 3a and 3b. The top of the plant housing device 1 is profiled to accommodate the irrigation means 10. Preferably, the profile 11 is substantially configured to suit the configuration of the irrigation means 10 such that the irrigation means 10 sits securely in the profile 11. A close-up view of the profile for accommodating the irrigation means 10 is shown in FIG. 3a and 3b, whereby a U-shaped channel is provided to receive the irrigation means 10 having a cylindrical pipe configuration. The irrigation means of adjacent modular plant housing devices may be connected together and may further be connected to a central irrigation pipe, which will be described later.
Besides providing the possibility of having an integrated irrigation system within the plant housing device 1 , the design of the plant housing device 1 also allows easy access to the irrigation means 10 for maintenance or replacement purposes.
The back cover 6a and the front cover 6b are connected and locked in place by means of a snap-on configuration as illustrated in FIG. 3b. A protrusion 16a is provided on a side wall of the back cover 6a. A recess 16b is provided on a side wall of the front cover 6b. The protrusion 16a and the recess 16b are configured in such a way that their shapes and their locations correspond to each other, and the protrusion 16a fits tightly in the recess 16b when the casing 6 is closed. Besides being able to provide a tight fit, preferably the protrusion 16a and the recess 16b are being able to be pulled apart with sufficient force so that the front cover 6b may be opened to provide access to the plant substrates for maintenance purposes. Other interlocking configurations are also possible. For example, the casing 6 may be held closed by means of screw and nut or spring lock and socket or ledges or snap-lock joints or studs. FIG. 7a-c show one embodiment where studs are used as locking means. FIG. 7a shows the front cover 6b having four recesses 54 for accommodating studs 52 at each comer. FIG. 7b shows the back cover 6a having four recesses 56 for accommodating studs 52 at corresponding corners. FIG. 7c shows the assembled casing 6 with the studs 52 securely fastened into the recesses 54, 56, thereby interlocking the front cover 6b and back cover 6a by a rotating action of the studs 52. The casing is designed to have a front cover and a back cover interlocked in a simple manner such that the front cover is easily opened to facilitate placement or removal of plant substrates. Advantageously the casing 6 and the studs 52 are formed of lightweight and resilient materials such as polypropylene and high density polyethylene (HDPE) so that the modular plant housing device 1 is easily installed with minimal manpower. Recesses 34 are also provided on an edge wall of the back cover 6a and/or front cover 6b. The edge wall recess 34 receives a flange 28 of an intermediate connector 18, which will be described later. Edge wall recess at the bottom may also receive a flange 28 of an intermediate connector 18.
The plant housing device 1 further comprises a drainage means 12 located at the bottom of the plant housing device 1, as shown in FIGS. 1, 2 and 4. The bottom of the plant housing device 1 is profiled so that excess fluid (e.g. water and fertilizer) is not retained in the plant housing device 1, but instead the excess fluid is being drained away via the drainage means 12. Conveniently, the profile 13 is substantially configured to form a U-shaped channel to receive the drainage means 12 having a cylindrical pipe configuration. The drainage means of adjacent modular plant housing devices may be connected together and may further be connected to a central drainage down pipe, which will be described later.
Alternatively, as illustrated in FIG. 8 the profile of the bottom of the plant housing device 1 is sloped towards an orifice 60 located conveniently at the centre of the bottom so that excess water is drained off by gravity in a vertical manner via a discharge pipe 58. It is to be understood that the orifice 60 may be located off- centre or towards one end of the bottom. The discharge pipe 58 may be formed of a cylindrical shape having a flange at one end of the pipe. The flange at one end of the pipe enables the discharge pipe 58 to sit on the bottom of the plant housing device 1 when the discharge pipe 58 is inserted through the orifice 60. At times when leakage of water from the plant housing device 1 is not desired, for example during transport or maintenance, the orifice 60 may be sealed off with a stopper 62 shown in FIG. 8. The drainage means of adjacent modular plant housing devices may be connected together and may further be connected to a central drainage pipe arranged substantially horizontal but with a gradient to drain off the excess water by gravity.
Besides providing the possibility of having an integrated drainage system within the plant housing device 1, the design of the plant housing device 1 also prevents accidental spill of excess fluid from a plant housing device positioned at a higher level to a plant housing device positioned at a lower level. Optionally, a pest netting 14 may be provided near the bottom of the plant housing device 1 but above or sitting on the profile 13 for the drainage mean 12, as shown in FIG. 2. The pest netting 14 prevents pests such as mosquitoes and toads from entering and propagating in the drainage system. Further, the pest netting 14 also prevents clogging of the drainage system due to particles or leaves falling from above.
FIG. 5a illustrates schematically the irrigation system and drainage system in an assembly of modular plant housing devices 1. In the matrix configuration as shown, the irrigation means 10 of adjacent plant housing devices 1 in each row are connected to one another. A first end of the irrigation means 10 of the plant housing device 1 at a corner of the top row is connected to a pressure-regulated water supply. A second end of the irrigation means 10 of the plant housing device 1 at another corner of the top row farthest from the first end is connected to a third end of the irrigation means 10 of the plant housing device 1 at a corner of a lower row. During operation, water enters at the first end and flows through each plant housing device 1 in the top row sequentially. When it reaches the second end, water flows down to the lower row and continues to flow through each plant housing device 1 in the lower row. The flow of water continues in a similar snaking pattern until it reaches the bottom row where each plant housing device 1 in the assembly has been watered. In this illustration, water in the irrigation means 10 flows by gravity means and in one directional without requiring pumps. Excess water then exits the irrigation system and joins the drainage system via a drainage outlet pipe. Similarly, the drainage means 12 of adjacent plant housing devices 1 are connected to one another in each row. Unlike the irrigation system which forms a snaking pattern so that water flows through each plant housing device 1 in the assembly, the drainage means 12 connected in each row are connected via the drainage outlet pipe at one side of the assembly. Excess water after irrigation is collected and drained by the drainage means 12 in each row, and eventually drained out of the assembly by the drainage outlet pipe. The assembly of the plant housing devices 1 each having integrated irrigation system and drainage system provided in this manner has the advantage of avoiding or alleviating the problems caused by salt burn faced in prior art devices since (i) only fresh water is irrigated to each plant housing device 1 , and (ii) fertilizers leached in each plant housing device 1 are drained away immediately without contaminating other plant housing devices 1.
In FIG. 5b, an assembly 15 of a plurality of modular plant housing devices 1 is shown for vertical landscaping, for example, for mounting onto the facade of a building to provide greenery. Each individual modular plant housing device 1 is attached to two vertical railings 17 by means of top connectors 20, bottom connectors 19, and/or intermediate connectors 18. The plant housing device 1 is installed such that the back cover 6a is attached to the vertical railings 17 while the openings 7 on the front cover 6b faces away from the vertical railings 17. The top connector 20 (the mirror image being the bottom connector 19) and intermediate connector 18 are illustrated in FIG. 6b and FIG. 6c, respectively. The intermediate connector 18 is shown to have a substantially C-shape configuration formed of a top wall 26 and a bottom wall 24 joined by a side wall 22. At the opposing end of the side wall 22 where the top wall 26 and the bottom wall 24 are free-standing, an upward-extending flange 30 extends from the top wall 26 while a downward- extending flange 28 extends from the bottom wall 24. A securing means 32 is provided on the side wall 22 for securing to the vertical railings 17 when installed. The top connector 20 has a similar configuration as the intermediate connector 18, except that it does not have a top wall 26 and an upward-extending flange 30. FIG. 6a shows the intermediate connectors 18 when it is in use. The downward- extending flange 28 extends from the bottom wall 24 of the intermediate connector 18 and is received in the recess 34 provided on the edge wall of the back cover 6a and front cover 6b. Other alternative attaching means for the plant housing devices 1 are also possible, for example, hooks provided on the back cover 6a are slotted into recesses provided on the vertical railings 17.
The afore-described plant housing device provides several advantages outlined as follows: -
(a) When the plant substrates are each contained in individual geotextile bags, the problem of settling and disintegrating of substrates due to their containment in a single big geotextile bag is avoided. In addition, in the event when replacement of plant substrates is needed, the compartmentalized substrate container design allows ease for doing so since the plant substrates are now contained in individual geotextile bags.
(b) The number of compartments formed in the substrate container is adjustable to suit the desired outlook of the device. In addition, the size of each compartment is also adjustable to achieve different effects.
(c) The integrated irrigation system and the profile for receiving the irrigation means provided at the top of the plant housing device allows easy reach to the irrigation means for maintenance purposes.
(d) The integrated drainage system overcomes the problems associated with salt burn since excess water and fertilizers are drained away via the drainage outlet pipe without contaminating other plant housing devices.
(e) The front cover is designed for easy opening for easy maintenance.
(f) The plant housing device is made of lightweight material so that minimal manpower is needed for installation and maintenance. Although the foregoing invention has been described in some detail by way of illustration and example, and with regard to one or more embodiments, for the purposes of clarity of understanding, it is readily apparent to those of ordinary skill in the art in light of the teachings of this invention that certain changes, variations and modifications may be made thereto without departing from the spirit or scope of the invention as described in the appended claims.
