Description

Technical Field

[0001] This invention relates to the greening of buildings, particularly greening by means of plants, especially climbing plants, which are removably fixed. Background Technology

[0002] In today's ecological environment, greening urban spaces is becoming a real climate challenge. In particular, greening building facades is increasingly favored, whether for climate reasons, to support biodiversity, or to prevent damage (such as graffiti). Currently, installing grid or trellis systems on facades to be greened remains the preferred technique, especially when plants cannot be secured by their own hooks, tendrils, suckers, or aerial roots.

[0003] This technology has several drawbacks: the plants are permanently fixed to the facade, sometimes reaching tens of meters above the ground, making their maintenance complex, expensive, and risky. In fact, maintaining tall climbing plants on building exteriors requires heavy equipment such as scaffolding and high-altitude work platforms, and poses a risk of injury to workers.

[0004] Therefore, it is necessary to improve the maintenance of plants fixed to the exterior walls of buildings.

[0005] Therefore, the object of the present invention is to achieve the maintenance of such plants by installing a device on the exterior wall of the building in question, allowing these plants (preferably climbing plants) to be removably fixed to the exterior wall and, more preferably, temporarily removed from the exterior wall. This makes the plants easily accessible, allowing one person to care for them: removing the plants from the building from the ground (or more generally, from where the plant's roots are located), performing maintenance, and then returning them to their original position. Furthermore, the possibility of temporarily removing the plants from the exterior wall allows work to be performed on the exterior wall itself: maintenance, glass replacement, relocation, etc. Summary of the Invention

[0017] definition In this invention, the following terms are defined as follows.

[0018] A "planting trough" refers to a container (flowerpot, planting box, can) used to receive plants. As an extension, a planting trough can also be for off-soil planting, planting pits, or even ground planting. In such cases, the anchoring device integrated with the planting trough can be a pile, a slab, or a heavy block placed in the soil.

[0019] "Building" refers to any type of building (apartment building) and its components: interior walls, exterior walls, facades, or roof; having a vertical, horizontal, or any other desired orientation. As an extension, a building can be a collection of multiple buildings (apartment buildings) with green spaces simultaneously supported on multiple buildings. For example, a green space may span a courtyard or street, or be located at a corner between multiple buildings. Buildings include residential buildings (detached houses, multi-family buildings, garages), work or service buildings (workshops, factories, logistics centers, office buildings, museums, parking lots, commercial parking), and civil engineering structures (bridges, sound barriers, hoppers, canals, antennas), etc.

[0020] “Entangling” refers to the way climbing plants climb on supports. Here, the word “entangling” encompasses support points (such as thin sheets fixed to a trellis system); or hooks (achieved by attachments of the plant or artificial attachments); or entanglements (wrapping, such as tendrils).

[0021] "Exterior wall" refers to the part of the building that is to be greened.

[0022] A "trellis system" refers to a support structure to which climbing or trailing plants can be secured (e.g., by twining) during their growth. A trellis system can have any shape suitable for plant growth. It can be a lattice, a mesh, or any type of wire mesh. A trellis system can also support the roots of plants in a pot. Furthermore, the overall shape of the trellis system surface is not necessarily limited. For example, it can be planar or tubular.

[0023] "Climbing plants" are plants whose stems require support to climb. These plants cannot climb without support. Some plants develop organs that allow direct attachment to supports (hoops, suckers, tendrils, aerial roots). Others twine around supports: for non-twining plants, the plant needs to be tied to a support. For twining plants, the plant's own structures (through stems, leaves, or tendrils) twine around the support without direct attachment. Without support, climbing plants become creeping plants (if their roots are on the ground) or trailing plants (if their roots are at a height). Attached Figure Description

[0030] Exemplary embodiments of the present invention Figure 1 The operation of the removable greening device is illustrated. A planting trough is installed at the base of a high-rise building. A pin is contained within the planting trough. A removable support in the form of a 3mm diameter metal cable is secured to the pin. A tensioning system is installed on the building's roof, with the cable engaged within it. A morning glory (Ipomoea) grows by winding around the cable.

[0031] exist Figure 1 On the left, the cables are in a tensioned configuration: the cables are aligned with the facade, and the plants are close to the facade.

[0032] To ensure the maintenance of the plants, the cables were loosened. Figure 1 (On the right side), to switch to a relaxed configuration. Plants wrapped around the cables are moved away from the facade and closer to the ground, where gardeners can maintain the plants or the facade.

[0033] Then, the cable will return to its tensioned configuration to put the greening device back in place.

[0034] Figure 2 Different removable greening devices for climbing plants are shown on a high-rise building.

[0035] Figure 1 The device is displayed in the center of the building.

[0036] On the left side of the building, a device comprising planting troughs with two pins is placed on a balcony (accessible to pedestrians). A cable is secured to each pin, and each cable is engaged with a tensioning system located on the building's roof. The tensioning system is equipped with an electric winch controlled by an electrical control box (not shown) placed on the planting trough. Between the two cables is a trellis system in the form of a woven net with an average mesh size of 10 cm. A *Aristolochia* plant grows by winding around the trellis system. Controlling the two winches loosens the cables, bringing the trellis system and plant back to the balcony, and then tightens the cables to return the trellis system and plant to the exterior facade.

[0037] On the right side of the building, a device comprising planting troughs with two pins is placed on the ground. A cable is secured to each pin, and each cable engages with a pulley located at the top of the building, which directs the cable toward a tensioning system placed on the ground next to the planting trough. The tensioning system is equipped with an electric winch. Between the two cables is a trellis system in the form of a woven mesh with an average mesh size of 10 centimeters. An Akebia quinata plant grows by winding around the trellis system. Controlling the two winches loosens the cables, bringing the trellis system and plant back to the ground, and then tensions the cables to return the trellis system and plant to the facade.

[0038] Figure 3 Different removable greening devices for hanging plants are shown on a high-rise building.

[0039] On the left side of the building, a planting trough is installed on the roof of the high-rise building. A pin is contained within the planting trough. A removable support in the form of a 3mm diameter metal cable is fixed to the pin. On the ground, directly below the planting trough, a tensioning system is installed, in which the cable is engaged. A passionflower hangs down, its tendrils wrapped around the cable.

[0040] To ensure the plants are maintained, the cables are loosened and pulled upwards, bringing the plants wrapped around them to the roof where gardeners can perform the necessary maintenance. The cables are then returned to their tensioned configuration to put the greening installation back in place.

[0041] On the right side of the building, a device comprising planting troughs with two pins is installed on the roof of the high-rise building. A cable is secured to each pin, and each cable engages with a tensioning system placed on the ground, directly below the planting trough. The tensioning system is equipped with an electric winch. Between the two cables is a trellis system in the form of a woven mesh with an average mesh size of 10 cm. A clematis plant cascades down by its leaves winding around the trellis system. Controlling the two winches loosens the cables, bringing the trellis system and plant back to the roof, and then tightens the cables to lower the trellis system and plant back onto the facade.

[0042] Figure 4 Different multi-directional removable greening devices are shown on high-rise buildings.

[0043] On the front facade, a device comprising planting troughs with two pins is placed on the ground. A cable is secured to each pin. One cable engages with a pulley placed on the building's balcony, which returns the cable to a tensioning system placed on the ground next to the planting trough. A second cable engages with the tensioning system on the building's balcony at a 30° angle to the vertical. The tensioning system is equipped with an electric winch, which is remotely controlled and placed on the balcony. Holboellia coriacea (not shown) grows by being wound around the cable. By controlling the two winches, the cable can be loosened to bring the plant back to the ground and then tensioned to return the plant to the facade.

[0044] In addition, a multi-directional device is installed, in which a planting trough is located on the ground and includes pins. A cable is secured to the pins, which engages in a pulley placed on the roof of the building, and turns the cable to the other end of the roof (thus along a horizontal path) until a second pulley, which turns the cable to a tensioning system placed on the ground. A wisteria vine climbs by wrapping itself around the cable and then creeping along it.

[0045] To ensure the maintenance of the plants, the cables are loosened, bringing the plants wrapped around them to the ground where gardeners can perform the necessary maintenance. The cables will then be tensioned back to allow the greening installation to be placed back on the facade and roof.

[0046] Figure 5 Different removable planting devices are shown on a detached house.

[0047] A device comprising a planting trough with two pins is installed beneath a protruding section of a detached house. A cable is secured to each pin, and each cable engages with either a pulley (left) or two pulleys (right) positioned beneath the protrusion. These pulleys return the cable to a tensioning system placed on the ground. Between the two cables is a trellis system in the form of a woven net with an average mesh size of 10 centimeters. A kiwi (Actinidia) plant grows by winding around the trellis system. Controlling two winches loosens the cables, bringing the trellis system and plant to the ground, and then tightens the cables to return the trellis system and plant to their original position as plant dividers.

[0048] A similar Figure 3 The device shown on the left is installed from the terrace of a detached house.

[0049] In other implementations, for example Figure 6 As shown, removable greening devices are arranged in the parking lot to shade at least one vehicle space. To improve... Figure 6 For readability, only the trellis system 18 and planting trough 20 are shown. In other words, the anchoring device 10, removable support 12, tensioning system 14, return device 16, and building are shown. Figure 6 The middle part is omitted.

[0050] In some configurations, the trellis system 18 may include at least one angle. For example, the trellis system 18 may include a vertical portion 181 and a horizontal portion 182. A planting trough 20 may then be attached to the vertical portion of the trellis system 18, from which climbing plants begin to grow on the vertical portion 181 and then on the horizontal portion 182. The horizontal portion 182 is then configured to shade vehicle space. In other examples, the climbing plants may grow on the ground.

[0052] This invention relates to a removable greening device for buildings. The device is designed to place plants near the exterior walls of a building while allowing for their temporary removal.

[0053] The removable greening device includes an anchoring device 10 designed to be secured to a building. This anchoring device ensures the device's fixed and stable positioning. The anchoring device 10 can be an anchor point, such as a pin, ring, hook, load-bearing wire, hanging rod, solid block (concrete cube), rock, etc. The anchoring device can advantageously be integrally formed with a planting trough 20 for receiving the plants.

[0054] The removable greening device also includes a removable support 12. The removable support 12 includes a first fastening device at its first end, which is to be secured to an anchoring device. Therefore, its first end is fixed relative to the building, close to the location where the plant roots will be installed.

[0055] Finally, the removable greening device includes a tensioning system 14. The second end of the removable support 12 engages in the tensioning system 14, which allows the removable support 12 to be held in a locking configuration by applying a tension force, and allows the removable support 12 to slide freely in a sliding configuration. Thus, the removable support 12 is secured to the anchoring device 10 and the tensioning system 14, but the removable support 12 can be tensioned or conversely released. In the tensioned configuration, the removable support 12 is close to the exterior wall of the building. In the released configuration, the removable support 12 can be moved away from the exterior wall of the building.

[0056] Greening is achieved through the plant growth support function of the removable support 12. Two implementations are possible. Either the removable support 12 is a linear support around which plants can partially wrap, spontaneously for climbing plants and using attachment members for non-climbing plants. Here, "partially" means that the plant will wrap around at most a portion of the removable support 12 located between the anchoring device 10 and the tensioning system 14 (in the tensioned configuration). Or the removable support 12 includes a trellis system 18 on which climbing plants can partially wrap. Preferably, the trellis system 18 extends at most between the anchoring device 10 and the tensioning system 14 (in the tensioned configuration). Similarly, "partially" here means that the plant will wrap around all or part of the trellis system 18. Plants can wrap onto the removable support 12 by natural wrapping or by means of attachment members (e.g., ropes, elastic bands, loops). The attachment member is configured to allow at least one plant branch (preferably a creeping branch) to be inserted between the attachment member and the removable support 12, thereby capturing the branch between the attachment member and the removable support 12. For example, each attachment member is generally hook-shaped or ring-shaped.

[0057] Therefore, the greening device provides mechanical support for the plants via removable support 12. In the tensioned configuration, the plants are close to the building and extend from anchor 10 to tension system 14. Because this mechanical support can be moved away from the building, the greening device can be removed. In fact, if needed, the tension on the removable support 12 can be released and it can be slid into tension system 14. The plants remain wrapped around the removable support 12 (or trellis system 18) and move naturally toward the ground with the removable support 12 (for climbing plants), allowing access to the building's exterior walls or for plant maintenance (pruning, trellising, thinning), with the plant roots at ground level—or, for plants placed on balconies or terraces, at the building level—without the use of heavy and expensive equipment such as aerial work platforms or scaffolding. The risk of plant damage is also reduced. For hanging plants, the same principle applies, with anchor 10 placed at the top and the rest of the device at the bottom: this allows the hanging plants to be lifted upwards away from the building. After the plants are maintained or the exterior wall is intervened, the plants are returned to their original positions by restoring the tensioned configuration of the removable support 12.

[0058] Furthermore, compared to current lattice systems or mesh supports that require numerous anchor points on the exterior walls, using the disclosed device to green buildings can limit the number of holes that need to be drilled into the building.

[0059] In one embodiment particularly suitable for greening climbing plants that are directly hooked onto their supports, the removable support 12 is installed in a way that prevents the climbing plants from contacting the building's exterior wall. In the tensioned configuration, a distance of 50 cm or 1 m between the exterior wall and the removable support is suitable. This spacing also benefits plant development, providing more accessible space and allowing for better light exposure.

[0060] The size of removable greening devices after installation depends primarily on the building to be greened and the plants used.

[0061] For Wisteria planting, the planting height can reach 30 meters. In this case, the length of the removable support 12 is between 5 meters and 60 meters, and it will be made of stainless steel cable with a diameter of 5 millimeters.

[0062] For planting morning glories (Ipomoea), the planting height can reach 15 meters. In this case, the length of the removable support 12 is between 3 meters and 30 meters, and it will be constructed of stainless steel cable with a diameter of 3 millimeters.

[0063] It should be noted that the removable support 12 can consist of multiple interconnected sections connected by hooks, latches, or any other means of connection. In practice, the climbing plants to be placed on the removable greening device are typically prepared in the nursery along with their supports. During the initial growth stage of the plant, the support does not need to be very long. For example, the growth of wisteria can be initiated on a 4-meter-high cable. Then, once the climbing plant is in place, the initial 4-meter cable section is combined with a second section of appropriate length, depending on the height of the structure to be greened, to obtain the required removable support 12.

[0064] When the removable support 12 is a linear support, it can be selected from cables, chains, ropes, or wires (whether woven or not). The cross-section of the linear support can be circular, square, rectangular, or triangular. The linear support can also be a strip, preferably a perforated strip. Textile strips with a naturally woven structure are particularly suitable. Finally, the linear support can have surface irregularities (protrusions, depressions, points, grooves). The selection of the linear support will be a trade-off between durability (wind resistance, adhesion resistance), weight, tensile strength, linear expansion, and adaptability to plant growth.

[0065] Tensioning system 14 can be implemented using any known means. Preferably, tensioning system 14 includes winding system 141, such as a winder or winch. In practice, the winding device can prevent the untensioned portion of the removable support 12 in the tensioned configuration from being left on the ground (or building) and posing a risk to the user.

[0066] The tensioning system 14 can be remotely controlled, for example, by a control device placed near the anchoring device 10.

[0067] In one embodiment, the greening device further includes a return device 16 to be fixed to the building, and the removable support 12 is retracted in the return device 16, which is freely sliding. Therefore, this embodiment allows for adjustment of the path the plants will cover on the building and enables multi-directional greening.

[0068] Advantageously, the return device 16 is positioned at the top of the building (or the highest point the greening installation must reach), and the removable support 12, which slides within the return device 16, is retracted, allowing the tensioning system 14 to be placed close to the anchoring device 10. Thus, a system allowing the removal of plants from the building's exterior wall is located near the plant's roots. Temporary removal of the greening installation and plant maintenance can be easily performed by one person. In this advantageous embodiment, the plant is wrapped around the portion of the removable support 12 located between the anchoring device 10 and the return device 16 in the tensioning configuration. The return device 16 is advantageously selected from pulleys, rings, rods, or sliders.

[0069] In an embodiment particularly advantageous for high-altitude applications, the return device 16 is electrically driven to assist in tensioning or removing the removable support 12. An electric pulley is suitable for this purpose.

[0070] The removable greening device can be placed in any orientation compatible with the growth of the plant being considered. For example, the device can be vertical, with anchoring devices 10 arranged at the bottom (climbing plants) or the top (hanging plants). The device can also be inclined in a vertical plane. The device can also be horizontal: in this case, the plant would be referred to as a creeping plant. Finally, the device can be multi-directional, especially based on one or more return devices 16. In particular, the removable support 12 can be branched (or forked). In this case, the removable support 12 includes a main support and additional branches or forks. The removable support 12 is secured to the anchoring devices 10 by fastening devices at one end of the main support. And the removable support 12 is tensioned by a set of tensioning systems 14, each tensioning system acting on the main support or a branch.

[0071] A removable greening device can be installed to accommodate a group of climbing and / or hanging plants. Specifically, a removable greening device may include multiple removable supports 12, each of which is anchored and tensioned independently or collaboratively. For example, multiple removable supports 12 may be secured to an anchoring device 10 (e.g., an anchor rod) and tensioned using a single tensioning system 14 (e.g., a load-bearing bar). This device allows for removable greening of large building surfaces. If the removable supports 12 are substantially parallel, the greening surface is substantially rectangular. In another example, multiple removable supports 12 may be secured to an anchor point and tensioned using a load-bearing bar requiring only a single tensioning system 14. This device produces a fan-shaped greening effect.

[0072] For very large exterior wall greening projects, multiple removable greening devices as described above can be used in combination.

[0073] In one embodiment, each greening device includes 2 to 20 removable supports 12, and each device can be operated independently.

[0074] In another embodiment, a greater number of removable supports 12 (30 to 100) can be implemented. For example, a wide exterior wall (shopping mall, logistics warehouse) can have rotatably driven hooks mounted on its roof, behaving like winches and safely driven by motors. All the removable supports 12 tensioned by these winches can be released simultaneously to remove the entire greening installation from the entire exterior wall. This embodiment is advantageous when using annual plants (e.g., morning glory (Ipomoea)). In practice, the above-ground parts of the plant will dry out during the winter and remain on the removable supports 12. The dried greenery needs to be removed during maintenance so that the plant can regrow from its roots. The ability to remove the entire greening installation at once allows for quick and safe maintenance. In a typical installation, the removable supports 12 are distributed throughout the greening installation, spaced 1 to 2 meters apart, thus achieving good plant coverage and limiting growth competition between plants.

[0075] The present invention also relates to an assembly kit comprising the components required to construct the removable greening device for buildings disclosed above. The kit includes multiple components to be assembled together, including: At least one anchoring device 10 to be fixed to the building; At least one removable support 12 includes a first fastening device at its first end to be secured to the anchoring device 10; At least one tensioning system 14, configured as follows: In the locking configuration, the removable support 12 remains tensioned; or In the sliding configuration, the removable support 12 is allowed to slide freely.

[0076] The removable support 12 is a linear support around which climbing plants can partially wrap around; or, the removable support 12 includes a trellis system 18 around which climbing plants can partially wrap around.

[0077] The linear support can be selected from cables, chains, ropes, or wires. The tensioning system 14 may also include a winding system 141, preferably selected from a winder or a winch.

[0078] The kit may also include at least one return device 16 designed to be fixed to a building, and the removable support 12 is folded back and can slide freely. The return device may be, for example, a pulley, ring, rod, shaft, or slider.

[0079] The present invention also relates to a method for installing a removable greening device on a building. The method includes the following steps: Secure the anchoring device 10 to the building; The removable support 12 is secured to the anchoring device 10 via its first end; Tensioning system 14 is configured as follows: In the locking configuration, the removable support 12 remains tensioned; or In the sliding configuration, the removable support 12 is allowed to slide freely; and The removable support 12 is engaged into the tensioning system 14.

[0080] The removable support 12 is a linear support around which climbing plants can partially wrap around; or, the removable support 12 includes a trellis system 18 around which climbing plants can partially wrap around.

[0081] This method can be implemented on completed buildings. It can also be implemented during the building construction process, allowing for the design of more accessible access to the tensioning system 14 and the aesthetic integration of the various components.

[0082] Finally, the present invention relates to a method for removing a greening device from a building. The greening device includes climbing plants wrapped around a removable support 12 or wrapped around a trellis system 18 fixed to the removable support 12. The removable support 12: It is fixed at its first end to the anchoring device 10 on the building; It is coupled in a tensioning system 14, which is configured as follows: In the locking configuration, the removable support 12 remains tensioned; or In the sliding configuration, the removable support 12 is allowed to slide freely.

[0083] The method includes the following steps: Release the tension applied to the removable support 12 by the tensioning system 14; and Slide the removable support 12 to allow the climbing plant to leave the building.

[0084] Furthermore, methods for removing greening devices from buildings may include one or more of the following steps, which are technically combinable: The tensioning system 14 is positioned in the locking configuration to secure the removable support 12 in the release configuration; Slide the removable support 12 to allow the climbing plant to be placed back onto the building; The tensioning system 14 is placed in the locking configuration to secure the removable support 12 in the tensioning configuration; Remove or retain the plant that is wrapped around the removable support 12; Plants are installed by inserting at least one branch or leaf between the attachment member and the removable support 12.

[0085] This method offers numerous advantages. It allows for the temporary removal of greening installations for plant or building maintenance. Furthermore, it avoids the use of heavy machinery for maintenance. Ultimately, the method can be implemented by a single operator.
