Description

Title of the invention: Removable greening device FIELD OF INVENTION

[0001] The present invention relates to the greening of buildings, and in particular greening by means of plants, especially climbing plants, attached in a removable manner. PRIORITY OF THE TECHNOLOGY

[0002] In the current ecological context, the greening of urban spaces is becoming a crucial climate issue. In particular, greening building facades is increasingly recommended, whether for climate reasons, to support biodiversity, or to prevent damage—graffiti, for example. Currently, installing wire mesh or trellising on the facade to be planted remains the preferred technique when plants cannot attach themselves using their tendrils, suckers, or aerial roots.

[0003] This technique has several drawbacks: the plants are permanently attached to the facade, sometimes reaching heights of several tens of meters, making their maintenance complicated, costly, and risky. Indeed, maintaining a climbing plant at a great height on a facade requires heavy equipment such as scaffolding and a platform, and poses a risk of injury to the person performing the maintenance.

[0004] There is therefore a need for improved maintenance of plants attached to a building facade.

[0005] The present invention therefore aims to enable the maintenance of such plants, preferably climbing plants, by installing on the facade of the building concerned a device allowing for the removable attachment and, preferably temporary, removal of these plants from the facade. Thus, the plants become easily accessible so that a single person can maintain them: moving the plant away from the building by bringing it closer to the ground—or more generally, to their own foot—carrying out the necessary maintenance, and returning it to its place. Furthermore, the possibility of temporarily removing the plants from the facade allows work to be carried out on the facade itself: maintenance, replacement of glazing, or relocation, for example.

DEFINITIONS

[0017] In the present invention, the terms below are defined as follows.

[0018] “Growing tray” refers to a container (pot, planter, tray) intended to receive a plant. By extension, a growing container can also be a raised bed, a planting pit, or even a direct in-ground planting. In this case, a means of anchoring the growing container securely can be a stake, a buried plate, or a heavy block placed in the ground.

[0019] “Building B” refers to all types of buildings and their elements: interior walls, walls Exterior, facade, or roof; having a vertical, horizontal, or any other desired orientation. By extension, the building can be a group of several buildings, with the greening projecting across multiple buildings simultaneously. This is the case, for example, with greening spanning a courtyard or street, or at the corner between several buildings. Buildings include residential buildings – single-family homes, apartment buildings – work or service buildings – workshops, factories, logistics centers, office buildings, museums – commercial buildings, as well as engineering structures – bridges, noise barriers, underpasses, canals, antennas, etc.

[0020] “Winding” refers to the way in which a climbing plant ascends its support. Here, the term to roll up covers a support - a leaf taking support on the trellis for example - or an attachment - by an attachment organ of the plant or by an artificial attachment organ - or a rolling - a tendril for example.

[0021] “Facade” refers to the part of the building intended to be planted with vegetation.

[0022] “Trellising” refers to a support on which a climbing or trailing plant It can twine as it grows. A trellis can take any form adapted to the growth of a plant. A trellis can be a mesh, a netting, a network of wires of any structure. A trellis can also support the base of a plant in a pot.

[0023] “Climbing plant” refers to a plant whose stems require support for to grow upwards. These plants cannot climb without support. Some plants develop organs that allow them to attach directly to a support – tendrils, suckers, aerial roots. Other plants twine around their support: For non-twining plants, it is necessary to tie them to a support. For twining plants, the plant's structure itself wraps around the support—using stems, leaves, or tendrils—without being directly attached. Without support, a climbing plant will be creeping—if its base is on the ground—or trailing—if its base is elevated. DETAILED DESCRIPTION

[0024] This disclosure relates to a removable building greening device. This device aims to place plants near the facades of a building while allowing them to be temporarily removed.

[0025] The removable greening system includes an anchoring means 10 for fixing to the building. This anchoring means ensures a fixed and stable positioning of the system. The anchoring means 10 can be an anchor point such as a dowel, a ring, a hook, a support wire, a support bar, a solid block – concrete block, rock, etc. This anchoring means can advantageously be attached to a planting tray 20 for receiving the plant.

[0026] The removable greening system also includes a removable support 12. This removable support 12 includes at its first end a first fastening means intended to be fixed by the anchoring means. Its first end is therefore fixed relative to the building, near the location where the base of the plant will be installed.

[0027] The removable greening system also includes a tensioning system 14. The second end of the removable support 12 is engaged in the tensioning system 14, which, in a locked configuration, holds the removable support in place by potentially applying a tension force to it. In a sliding configuration, it allows the removable support 12 to slide freely. Thus, the removable support 12 is secured to the anchoring means 10 and the tensioning system 14, but it can be either tensioned or released. In the tensioned configuration, the removable support 12 is close to the building's facades. In the released configuration, the removable support 12 can be moved away from the building's facades.

[0028] Vegetation is made possible by the plant growth support function of the removable support 12. Two embodiments are possible. Either the removable support 12 is a linear support around which a plant can partially twine, spontaneously for a climbing plant, or with the aid of attachment points for a non-climbing plant. By partially, it is meant here that the plant will twine at most around the portion of the removable support 12 located between the anchoring means 10 and the tensioning system 14 in the tensioned configuration. Or the removable support 12 comprises a trellis 18 around which a climbing plant can twine Partially. Preferably, the trellis 18 extends at most between the anchoring means 10 and the tensioning system 14 in the tensioned configuration. Similarly, "partially" here means that the plant will twine around all or part of the trellis 18. The plant can twine around the removable support 12 by natural winding, or by means of a fastening element – ​​cord, elastic band, ring. A fastening element is configured to allow the insertion of at least one plant branch – preferably a climbing branch – between the fastening element and the removable support 12 in order to trap the branch between the fastening element and the removable support 12. Each fastening element has, for example, a general hook or loop shape.

[0029] The greening system thus constitutes, by means of the removable support 12, a mechanical support for the plants. In the tensioned configuration, the plant is close to the building and extends from the anchoring means 10 towards the tensioning system 14. As this mechanical support can be moved away from the building, the greening is removable. Indeed, if the need arises, it is possible to release the tension on the removable support 12 and slide it into the tensioning system 14.The plant remains wrapped around the removable support 12 – or the trellis 18 – and will naturally follow the removable support 12 towards the ground – in the case of a climbing plant – providing access to the building's facade or allowing for plant maintenance – pruning, training, thinning – with its roots on the ground – or on the building for plants placed on balconies or terraces – instead of having to use heavy and expensive equipment such as a cherry picker or scaffolding. The risk of damaging the plant is also reduced. In the case of a trailing plant, the same principle is implemented, with an anchor point 10 placed at the top and the rest of the device placed below: it is then possible to lift the trailing plant away from the building. After plant maintenance or work on the facade, the plant is put back in place, restoring the taut configuration of the removable support 12.

[0030] In addition, the greening of a building using the disclosed device makes it possible to limit the number of holes to be drilled in the building, compared to current supports of the trellis or wire mesh type which require a large number of anchor points on the wall.

[0031] In an embodiment particularly suited to greening by climbing plants that attach directly to their support, the removable supports 12 are installed so as to avoid contact between the climbing plants and the building facade. A distance of 50 cm, or even 1 m, between the facade and the removable supports in a tensioned configuration is suitable. This distance from the facade is also favorable to plant development by giving it more accessible space and better exposure to light.

[0032] The dimensions of the removable greening device, when installed, depend essentially on the building to be greened and the plants used.

[0033] For vegetation with wisteria, the vegetation height can reach 30 m. In this case, the removable support 12 has a length between 5 m and 60 m and will be made of a stainless steel cable with a diameter of 5 mm.

[0034] For vegetation with a morning glory (Ipomoea), the vegetation height can reach 15 m. In this case, the removable support 12 has a length between 3 m and 30 m and will be made of a stainless steel cable with a diameter of 3 mm.

[0035] It should be noted that the removable support 12 can be made up of several sections connected together by a hook, a carabiner, or any other means of connection. Indeed, the climbing plant to be installed on the removable greening system is generally prepared in a nursery, along with its support. This support does not need to be very long in the initial stages of the plant's growth. For example, the growth of a wisteria (Wysteria) can be initiated on a 4 m high cable. Then, once the climbing plant is in place, the first 4 m cable section will be completed by a second section of a length adapted to the height of the building to be greened, resulting in the desired removable support 12.

[0036] When the removable support 12 is a linear support, it can be chosen from cables, chains, ropes, or wires—braided or unbraided. The cross-section of the linear support can be round, square, rectangular, or triangular. The linear support can also be a strip, preferably perforated. A textile strip with a naturally formed mesh is particularly suitable. Finally, the linear support can have surface irregularities—bumps, hollows, points, notches. The choice of the linear support will be a compromise between resistance (to wind, to snagging), weight, tensile strength, linear expansion, and adaptation to plant growth.

[0037] The energizing system 14 can be implemented using any known device. Preferred energizing systems 14 include a winding system 141, such as a reel or a winch. A winding device prevents the portion of the removable support 12 that is not under tension in the tensioned configuration from being left on the ground—or on the building—and potentially posing a risk to users.

[0038] The power-up system 14 can be controlled remotely, for example by means of a control device placed near the anchoring means 10.

[0039] In one embodiment, the greening device further comprises a return means 16 intended to be fixed to the building and in which the removable support 12 is folded and can slide freely. This embodiment allows thus to adjust the path that the plant will take on the building and to achieve multidirectional vegetation.

[0040] Advantageously, the guide means 16 is positioned at the top of the building—or at the highest point the vegetation needs to reach—and the removable support 12, which slides within the guide means 16, is folded so that the tensioning system 14 can be positioned near the anchoring means 10. Thus, the system that allows the plant to be moved away from the building's facade is located close to the base of the plant. The temporary removal of the vegetation and maintenance of the plant can easily be carried out by a single person. In this advantageous embodiment, the plant is wound around the portion of the removable support 12 located between the anchoring means 10 and the guide means 16 in the tensioned configuration. The guide means 16 is advantageously selected from pulleys, rings, bars, or slides.

[0041] In a particularly advantageous embodiment for great heights, the return means 16 is motorized to assist in tensioning or releasing the removable support 12. The motorized pulleys are adapted for this purpose.

[0042] The removable greening system can be installed in any orientation compatible with the growth of the intended plants. For example, the system can be vertical with the anchoring means 10 positioned at the bottom – climbing plant – or at the top – trailing plant. The system can also be inclined in a vertical plane. The system can also be horizontal: in this case, the plants will be described as creeping. Finally, the system can be multidirectional, relying in particular on one or more connecting means 16. In particular, the removable support 12 can be branched. In this case, the removable support 12 comprises a main support to which branches or offshoots are added. This removable support 12 is fixed to the anchoring means 10 by a fastening means on one end of the main support.And this removable support 12 is powered by a set of power supply systems 14, each operating on the main support or a branch.

[0043] A removable greening system can be installed to accommodate a variety of climbing and / or trailing plants. In particular, a removable greening system can comprise several removable supports 12, each anchored and tensioned independently or in conjunction with another. For example, several removable supports 12 can be attached to a single anchoring means 10—for example, an anchor bar—and tensioned using a single tensioning system 14—for example, a support bar. Such a system allows for the removable greening of a large building area. If the removable supports 12 are substantially parallel, the greened area is substantially rectangular. In another example, several removable supports 12 can be fixed to a single anchor point and tensioned using a support bar requiring only a tensioning system 14. This arrangement results in a fan-shaped greening.

[0044] For greening very large facades, several removable greening devices as described above can be used together.

[0045] In one embodiment, each of the vegetation devices comprises from 2 to 20 removable supports 12, each of these devices being operable separately.

[0046] In another embodiment, an even larger number of removable supports 12 – from 30 to 100 – can be used. For example, a large façade – such as a shopping center or logistics warehouse – can have rotating lifting bars on its roof, acting as winches, driven by a single motor. All the removable supports 12, tensioned by these winches, can be simultaneously released to lower the entire vegetation covering the façade. This embodiment is advantageous when annual plants are used, such as morning glories (Ipomoed). The above-ground parts of the plants will dry out in winter and remain on the removable supports 12. Before the plants regrow from their roots, the dried vegetation will need to be removed during maintenance. The ability to lower the entire vegetation at once allows for quick and safe maintenance.In a typical setup, the 12 removable supports are distributed throughout the greening system to be separated by 1 m to 2 m, leading to good plant cover and limiting growth competition between plants.

[0047] This disclosure also relates to an assembly kit comprising the elements necessary for installing a removable green roof system on a building as disclosed above. This kit comprises a plurality of elements to be assembled together and includes: - at least one anchoring means 10 intended to be fixed to the building; - at least one removable support 12 comprising at one end, a first means of fixing intended to be fixed to the anchoring means 10; - at least one power-up system 14 configured for • maintain the removable bracket 12 under tension in a locked configuration; or • allow the removable support 12 to slide freely in a sliding configuration.

[0048] The removable support 12 is a linear support around which a climbing plant can partially wrap itself; or alternatively the removable support 12 comprises a trellis 18 on which a climbing plant can partially wrap itself.

[0049] The linear support can be selected from a cable, chain, rope, or wire. The tensioning system 14 can also include a winding system 141, preferably selected from reels or winches.

[0050] The kit may further include at least one means of redirection 16 intended to be fixed to the building and in which the removable support 12 is folded and can slide freely, this means of redirection being for example a pulley, a ring, a bar, an axle or a slide.

[0051] This disclosure also relates to a method for installing a removable green roof system on a building. This method includes the following steps: - attaching an anchoring means 10 to the building; - the fixing by means of anchorage 10 of a removable support 12 by its first end; - the installation of a power supply system 14 configured for • maintain the removable bracket 12 under tension in a locked configuration; or • allow the removable support 12 to slide freely in a sliding configuration; and - the engagement of the removable support 12 in the power-up system 14.

[0052] The removable support 12 is a linear support around which a climbing plant can partially wrap itself; or alternatively the removable support 12 comprises a trellis 18 on which a climbing plant can partially wrap itself.

[0053] This method can be implemented on a completed building. It can also be implemented during the construction of the building, which makes it possible to design easy access to the power supply systems 14, and to integrate the various elements in an aesthetically pleasing manner.

[0054] Finally, this disclosure relates to a method for removing vegetation from a building. This vegetation comprises a climbing plant wound around a removable support 12 or on a trellis 18 attached to a removable support 12. The removable support 12 is - fixed at one end to an anchoring means 10 on the building; - engaged in one of a power-up system 14 configured for • maintain the removable bracket 12 under tension in a locked configuration; or • allow the removable support 12 to slide freely in a sliding configuration.

[0055] The method comprises the steps of - release the tension exerted on the removable support 12 by the power-up system 14; and - slide the removable support 12 so that the climbing plant is away from the building.

[0056] Furthermore, the method for removing vegetation from a building may include one or more of the following steps, in technically compatible combinations: - place the power-up system 14 in the locked configuration to immobilize the removable support 12 in the released configuration; - slide the removable support 12 so that the climbing plant is put back in place on the building; - place the power-up system 14 in the locked configuration to immobilize the removable support 12 in the tensioned configuration; - remove or maintain a plant wrapped around the removable support 12; - install a plant by inserting at least one branch or leaf between a attachment device and removable support 12.

[0057] This method offers numerous advantages. It allows for the temporary removal of a vegetation system, either for plant maintenance or for building maintenance. Furthermore, this method eliminates the need for heavy machinery for maintenance. Finally, the method can be implemented by a single operator. DESCRIPTION OF THE FIGURES

[0063] Figure 1 illustrates the operation of a removable greening system. A growing tray is installed at the base of a high-rise building. A peg is embedded in the growing tray. A removable support in the form of a 3 mm diameter metal cable is attached to this peg. A tensioning system into which the cable is inserted is installed on the roof of the building. A morning glory (Ipomoea) grows by twining around the cable.

[0064] On the left of [Fig.1], the cable is in a taut configuration: the cable is aligned with the facade and the plant is close to the facade.

[0065] To facilitate plant maintenance, the cable is slackened – to the right of [Fig. 1] – to move to a slack position. The plant, wrapped around the cable, is moved away from the facade and closer to the ground, where a gardener can perform maintenance on the plant or the facade.

[0066] Next, the cable will return to a tensioned configuration to replace the vegetation.

[0067] Fig. 2 illustrates various removable vegetation devices for climbing plants on a high-rise building.

[0068] The device of [Fig.1] is repeated in the centre of the building.

[0069] To the left of the building, a device comprising a growing tray on which are Two anchors are positioned on a balcony (freely accessible to pedestrians). A cable is attached to each anchor, and each cable is connected to a tensioning system located on the building's roof. The tensioning systems are equipped with electric winches controlled by an electrical box (not shown) located on the growing tray. A trellis, consisting of a textile net with an average mesh size of 10 cm, extends between the two cables. A Dutchman's pipe (Aristolochia) grows by twining around the trellis. The two winches allow the cables to be slackened to pull the trellis and plant towards the balcony, and then tightened to reposition the trellis and plant on the facade.

[0070] To the right of the building, a device comprising a growing tray on which two pegs are placed is positioned on the ground. A cable is attached to each peg, and each cable is engaged in a pulley located at the top of the building, which directs the cable to a tensioning system located on the ground next to the growing tray. The tensioning systems are equipped with electric winches. Between the two cables extends a trellis in the form of a textile net with an average mesh size of 10 cm. An akebia grows by twining itself around the trellis. The two winches allow the cables to be slackened to pull the trellis back and the plant on the ground, then tighten the cables in order to replace the trellis and the plant on the facade

[0071] Fig. 3 illustrates various removable vegetation devices for trailing plants on a high-rise building.

[0072] To the left of the building, a growing tray is installed on the roof of a high-rise building. A peg is embedded in the growing tray. A removable support in the form of a 3 mm diameter metal cable is attached to this peg. On the ground, directly above the growing tray, is a tensioning system into which the cable is inserted. A passionflower (Passiflora) falls by winding itself around the cable, thanks to its tendrils.

[0073] To ensure the plant's maintenance, the cable is slackened and raised, bringing the plant, wound around the cable, to the roof, where a gardener can perform the necessary maintenance. The cable is then returned to its taut position to reposition the vegetation.

[0074] To the right of the building, a device comprising a growing tray on which two pegs are placed is installed on the roof of a high-rise building. A cable is attached to each peg, and each cable is engaged in a tensioning system located on the ground, vertically above the growing tray. The tensioning systems are equipped with electric winches. Between the two cables extends a trellis in the form of a textile net with an average mesh size of 10 cm. A clematis (Clematis) falls by twining itself around the trellis thanks to its foliage. The two winches are used to slacken the cables to bring the trellis and the plant up to the roof, and then to tighten the cables to reposition the trellis and the plant on the facade.

[0075] Figure 4 illustrates various multidirectional removable vegetation devices on a high-rise building.

[0076] On the front facade, a device comprising a growing tray with two pegs attached to it is positioned on the ground. A cable is fixed to each peg. One of the cables is engaged in a pulley located on a balcony of the building, which directs the cable to a tensioning system located on the ground next to the growing tray. The second cable is engaged in a tensioning system located on the balcony of the building, at a 30° angle to the vertical. The tensioning systems are equipped with electric winches, the one located on the balcony being remotely controlled. Chinese blue vines (Holboellia coriacea, not shown) grow by twining around the cables. The two winches are used to slacken the cables to lower the plants to the ground, and then to tighten the cables to reposition the plants on the facade.

[0077] Furthermore, a multidirectional device is installed with a growing tray positioned on the ground and including a peg. A cable is attached to the peg and is engaged in a pulley located on the roof of the building. This pulley then directs the cable to the other end of the roof—along a horizontal path—to a second pulley, which in turn directs the cable to a tensioning system located on the ground. A wisteria (VF i steria) climbs by twining around the cable and then creeps along it.

[0078] To ensure the plant's maintenance, the cable is slackened, which brings the plant wrapped around the cable to the ground, where a gardener can carry out the necessary maintenance. The cable is then returned to its taut position to reposition the vegetation on the facade and roof.

[0079] Fig. 5 illustrates various removable greening devices on a detached house.

[0080] A device comprising a growing tray on which two pegs are placed is installed under an overhang of a detached house. A cable is attached to each peg, each cable being engaged in a pulley – on the left – or two pulleys – on the right – located under the overhang, which directs the cable to a tensioning system located on the ground. Between the two cables extends a trellis in the form of a textile net with an average mesh size of 10 cm. A kiwi (Actinidia) grows by twining itself around the trellis. The control of the two winches allows the cables to be slackened to bring the trellis and the plant down to the ground, and then tightened to reposition the trellis and the plant as a living screen.

[0081] A device similar to that shown in [Fig.3] to the left of the building is set up from a terrace of the detached house. NUMERICAL REFERENCES
