Description

FOLDING VEGETATION DEVICE FIELD OF INVENTION

[0001] The present invention relates to the greening of buildings, and in particular greening by plants, in particular climbing plants, fixed in a way that can be lowered. STATE OF THE ART

[0002] In the current ecological context, greening 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—such as graffiti. Currently, installing wire mesh or trellises 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. These plants pose a risk when the building experiences exceptional and potentially dangerous events such as fires. Indeed, the presence of vegetation on the building can exacerbate such events, particularly fires.

[0004] Therefore, there is a need to improve the safety of devices that fix plants to a building facade.

[0005] The present invention therefore aims to enable the securing of such devices by installing "fusible" elements capable of rapidly detaching, or detaching, said devices from the building. Thus, plants can be easily removed from the building in case of emergency, which greatly limits—or even eliminates—the risk of exacerbating exceptional events such as fires. SUMMARY

[0013] In certain configurations, the device further includes a means of redirection intended to be fixed to the building and in which the removable support is folded and can slide freely, said means of redirection including a fuse enabling the coupling between the means of redirection and the building to be broken.

[0014] In some configurations, the means of return is chosen from a pulley, a ring, a bar, an axle or a slide.

[0015] In some configurations, the removable support consists of a main support and branches, the first end of the removable support being a first end of the main support, with a set of power supply systems configured to: - maintain the main support and branches under tension in a locked configuration; or - allow the main support and branches to slide freely in a sliding configuration.

[0016] In some configurations, several removable supports are attached to an anchoring means; and a power supply system is configured to: - maintain all removable supports under tension in a locked configuration; or - allow all removable supports to slide freely in a sliding configuration.

[0017] In certain configurations, the power-up system is controlled remotely, preferably by means of a control device placed near the anchoring means.

DEFINITIONS

[0021] In the present invention, the terms below are defined as follows.

[0022] A "planting container" refers to a container (pot, planter, tub) designed to hold a plant. By extension, a planting container can also be a raised bed, a planting pit, or even a planting directly in the ground. In this case, a means of anchoring the planting container securely can be a stake, a buried plate, or a weighted block placed in the ground.

[0023] "Building" refers to any type of structure and its components: interior walls, exterior walls, facades, or roofs; whether vertical, horizontal, or any other desired orientation. By extension, a building can be a group of several buildings, with vegetation covering multiple buildings simultaneously. This is the case, for example, with vegetation spanning a courtyard or street, or at the corner between several buildings. Buildings include residential buildings—single-family homes, apartment buildings, garages—workplaces or service buildings—workshops, factories, logistics centers, office buildings, museums, parking lots—commercial buildings, as well as engineering structures—bridges, noise barriers, underpasses, canals, antennas, etc.

[0024] "Winding" refers to the way in which a climbing plant ascends its support. Here, the term "winding" covers a support - a leaf resting on the trellis for example - or an attachment - by a plant's own attachment organ or by an artificial attachment organ - or a winding - a tendril for example.

[0025] "Facade" refers to the part of the building intended to be planted with vegetation.

[0026] "Trellising" refers to a support on which a climbing or trailing plant can attach itself—for example, by twining around itself—as it grows. Trellising can take any form adapted to the plant's growth. It can be a trellis, a mesh, a network of wires, or any other type of structure. Trellising can also support the base of a plant in a pot. Furthermore, the overall shape of the trellis surface is not necessarily limited. It can, for example, be flat or tubular.

[0027] A "climbing plant" is a plant whose stems require support to grow upwards. These plants cannot climb without it. Some plants develop organs that allow them to attach directly to the support—tendrils, suckers, or aerial roots. Other plants twine around the support. For non-climbing plants, it is necessary to tie them to the 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 a creeping plant—if its base is on the ground—or a trailing plant—if its base is above it. DETAILED DESCRIPTION

[0028] This disclosure concerns a building greening system. This system aims to place plants near the facades of a building while allowing for their rapid removal.

[0029] Figure 1 represents a building greening device according to an embodiment of the present invention.

[0030] The greening system includes an anchoring device 10 intended to be fixed to the building. This anchoring device ensures a fixed and stable positioning of the system. The anchoring device 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 device can advantageously be attached to a planting tray 20 intended to hold the plant.

[0031] The greening system also includes a support 11. This support 11 includes at its first end a first fixing 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.

[0032] Support 11 can be flexible. In this discussion, a flexible object is a cohesive object capable of elastic deformation such that two distinct parts of that object can be brought into contact, provided that this deformation is reversible. For example, according to this discussion, a rope is flexible, a metal chain is flexible, a thin metal cable is flexible, but a steel beam is not flexible.

[0033] In general, when a flexible object is stretched out along its longest dimension, it tends to collapse reversibly under its own weight, under the action of gravity.

[0034] Furthermore, the greening system includes at least one coupling means 30 fixed to the building. The coupling means 30 is positioned higher than the anchoring means 10 in the direction of gravity or vertical direction. The coupling means 30 is configured to attach the support 11 to the building and allow the support 11 to extend vertically along the vertical direction.

[0035] Vegetation is made possible by the plant growth support function of support 11. Two embodiments are possible. Either support 11 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. "Partially" here means that the plant will twine at most around the portion of support 11 located between the anchoring means 10 and the coupling means 30. Or support 11 comprises a trellis 18 around which a climbing plant can partially twine. Preferably, the trellis 18 extends at most between the anchoring means 10 and the coupling means 30. Similarly, here we mean partially that the plant will wrap around all or part of the trellis 18. The plant can wrap around the support 11 by natural wrapping, or by means of a fastening device - cord, elastic, ring.A hooking member is configured to be able to insert at least one plant branch - preferably a climbing branch - between the hooking member and the support 11 in order to trap the branch between the hooking member and the support 11. Each hooking member has, for example, a general shape of a hook or loop.

[0036] 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 such as trellises or wire mesh which require a large number of anchor points or means of coupling on the wall.

[0037] In an embodiment particularly suited to greening with climbing plants that attach directly to their support, the supports 11 are installed in such a way as to prevent contact between the climbing plants and the building facade, or any element of the building to which the plant could attach and potentially damage, such as a gutter. A distance of 50 cm, or even 1 m, between the facade and the supports is appropriate.

[0038] The dimensions of the greening system, when it is put in place, depend essentially on the building to be greened and the plants used.

[0039] For planting with wisteria (Wisteria), the planting height can reach 30 m. In this case, the support will have a length between 3 m and 60 m and will consist of a stainless steel cable with a diameter of 5 mm.

[0040] For planting with a morning glory (Ipomoea), the planting height can reach 15 m. In this case, the support will have a length between 3 m and 30 m and will be, for example, made of a stainless steel cable with a diameter of 3 mm.

[0041] It should be noted that the support 11 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 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 (Wisteria) can be initiated on a 4-meter-high cable. Then, once the climbing plant is in place, the first 4-meter cable section will be completed with a second section of a length adapted to the height of the building to be greened, resulting in the desired support 11.

[0042] When the support 11 is a linear support, it can be chosen from among cables, chains, ropes, or wires—braided or not. 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, or notches. The choice of linear support will be a compromise between resistance (to wind, to snagging), weight, tensile strength, linear expansion, and adaptation to plant growth. The choice of support 11 may also depend on its method of attachment.

[0043] For the greening of very large facades, several greening systems as described above can cooperate.

[0044] In one embodiment, each of the vegetation devices comprises from 2 to 20 supports 11, each of these devices being operable separately.

[0045] In another embodiment, an even larger number of supports 11 - from thirty to one hundred - can be implemented.

[0046] The coupling means 30 includes a fuse. The fuse is a sacrificial element that has an integrated and an open configuration. When the fuse is in its integrated configuration, the coupling means 30 keeps the support 11 attached to the building. When the fuse is in its open configuration, the coupling means 30 leaves the support 11 free. In other words, when the fuse is in its open configuration, the support 11 can fall under the action of gravity. Otherwise, the support 11 is fixed to the building.

[0047] Furthermore, when the vegetation system includes a plurality of coupling means 30, each coupling means 30 includes a fuse.

[0048] The fuse can switch from the integrated configuration to the open configuration automatically and / or in a controlled manner.

[0049] When the configuration change is automatic, the greening system may include at least one sensor capable of measuring information and a controller to which the sensor is coupled. The controller is also connected to the fuse and capable of controlling it. Based on the information measured by the sensor, the controller is capable of recognizing a pre-recorded fuse breaking condition. When this condition is reached, the controller triggers the fuse to break, and the fuse switches to the open configuration.

[0050] The sensor is typically a smoke sensor. This smoke sensor can be coupled with a temperature sensor. Following this example, the controller can be able to recognize a fire and trigger the fuse to destroy it when a fire is detected.

[0051] When the configuration change is manual, the greening system may include an activator connected to the fuse. Activating the activator allows the fuse configuration to change from the integrated to the open configuration. This activator can be activated by an external operator.

[0052] The fuse can include both an automatic configuration change and a manual configuration change, each allowing the coupling to be broken independently of the other.

[0053] The fuse may include a sacrificial portion capable of self-destructing under certain conditions. In this case, the configuration change can be automatic without being controlled by a controller. For example, the fuse may include a thermal fuse cable, a gas or foam trigger, or a thermo-activated pyrotechnic mechanism.

[0054] The thermal cable is a component of the fuse that melts at a specific temperature (for example, between 70°C and 100°C). The melting of the thermal cable allows the fuse to switch from its intact to its open configuration.

[0055] The gas or foam trigger comprises a metal capsule capable of melting at a given temperature (for example, between 70°C and 100°C). The melting of the metal capsule releases a gas or a pressure mechanism, which allows the fuse to switch from its intact to its open configuration.

[0056] The fuse may also include a break pin or hook pin, a magnetic pin, or a locking pin. Generally, this type of fuse is reusable.

[0057] The snap pin or hook pin comprises a loop and a pull element. The support 11 can be enclosed in the loop of the pin. When the pull element is pulled, the loop opens, releasing the support 11.

[0058] The magnetic pin comprises a first electromagnet facing a second electromagnet or a permanent magnet. The first electromagnet provides a magnetic field that keeps the latter in contact with the second magnet when the first electromagnet is electrically powered. The support 11 can be attached to the second electromagnet. When the first electromagnet is powered, the support 11 is fixed. When the first electromagnet is not powered, the support 11 is free.

[0059] The locking pin includes a retaining mechanism and a push button capable of releasing the retaining mechanism when activated. The bracket 11 can then be attached to the retaining mechanism.

[0060] Using coupling devices, when a fire breaks out in the building to which the green roof system is attached, the system can be rapidly removed. Consequently, this significantly reduces—or even eliminates—the risk of the fire spreading to the green roof system. Furthermore, access to the building can be facilitated for emergency response teams. Finally, removing the green roof allows for better smoke evacuation and improved access for firefighting equipment such as water or foam.

[0061] In other embodiments, the greening system may be removable. In this case, the support 11 is a removable support 12 and includes a power supply system 14. When the greening system includes a power supply system, the coupling means 30 may be associated with one or more elements of the power supply system 14. Indeed, if the power supply system 14 is elevated, it must be able to be lowered and therefore it must be associated with a coupling means 30. Conversely, if the power supply system 14 is at ground level, associated with a return means 16 – see below – it is not necessary to associate it with a coupling means 30.

[0062] Regarding the removable greening system, the second end of the removable support 12 is engaged in the tensioning system 14. In a locked configuration, this system holds the removable support 12 in place, potentially applying tension 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 device 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.

[0063] The removable greening system, via its removable support 12, provides 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. Because this mechanical support can be moved away from the building, the greening is removable. Indeed, if needed, the tension on the removable support 12 can be released and it can be slid into the tensioning system 14.The plant remains wrapped around the removable support 12 – or the trellis 18 – and will naturally follow the 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 applied, with an anchor point 10 placed at the top and the rest of the system positioned 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.

[0064] 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. This is because 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.

[0065] The power-up system 14 can be controlled remotely, for example by means of a control device placed near the anchoring means 10.

[0066] In one embodiment, the greening system further includes a guide 16 for attachment to the building, in which the removable support 12 is folded and can slide freely. This embodiment thus allows adjustment of the path the plant will follow on the building and enables multidirectional greening. The guide 16 can also be connected to a coupling 30 comprising a fuse as described above.

[0067] Advantageously, the redirecting 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 redirecting means 16, is folded so that the tensioning system 14 can be placed near the anchoring means 10. Thus, the system for moving the plant away from the building's facade is located close to the base of the plant. 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 redirecting means 16 in the tensioned configuration. The redirecting means 16 is advantageously selected from pulleys, rings, bars, or slides.

[0068] 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.

[0069] The removable greening system can be installed in any orientation compatible with the growth of the intended plants. In particular, the system can be multidirectional, notably by using one or more connecting means 16. Specifically, 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 by means of an anchor 10 via a fastening means on one end of the main support. And this removable support 12 is energized by a set of energizing systems 14, each operating on the main support or a branch.

[0070] Furthermore, a removable green roof system can comprise several removable supports 12, each anchored and tensioned independently or in cooperation. For example, several removable supports 12 can be attached to a single anchoring point 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 green roof of a large building area. If the removable supports 12 are substantially parallel, the green roof area is substantially rectangular. In another example, several removable supports 12 can be attached to a single anchoring point and tensioned using a support bar requiring only one tensioning system 14. This system results in a fan-shaped green roof.

[0071] This presentation also concerns an assembly kit for a greening system based on one of the aspects described above; the kit comprises a plurality of elements to be assembled together, including: at least one anchoring means 10 intended to be fixed to a building; at least one support 11 comprising at a first end, a first fixing means intended to be fixed to the anchoring means 10; at least one coupling means intended to couple the support 11 to the building: in which the coupling means includes a fuse for breaking the coupling between the support 11 and the building.

[0072] The removable support 12 is a linear support around which a climbing plant can partially wrap itself; or alternatively the removable support 12 includes a trellis 18 on which a climbing plant can partially wrap itself.

[0073] 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.

[0074] 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.

[0075] This disclosure also relates to a method for installing a green roof system on a building. This method includes the following steps: the fixing of an anchoring means 10 on the building; the fixing of a coupling means 30 including a fuse on the building, the coupling means 30 being placed higher in the direction of gravity than the anchoring means 10; the fixing by means of anchorage 10 of a support 11, preferably a removable support 12, by its first end; the coupling of the support 11, preferably a removable support 12, to the building by means of coupling 30; in which: The support 11, preferably a removable support 12, is a linear support around which a climbing plant can partially twine; or the support 11, preferably a removable support 12, includes a trellis 18 on which a climbing plant can partially wrap itself.

[0076] The removable support 12 is a linear support around which a climbing plant can partially wrap itself; or alternatively the removable support 12 includes a trellis 18 on which a climbing plant can partially wrap itself.

[0077] This method can be implemented on a completed building. It can also be implemented during the building's construction, which allows for easy access to the power supply systems 14, and for the aesthetic integration of the various elements.

[0078] This disclosure finally concerns 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 a power supply system 14 configured for to maintain the removable support 12 under tension in a locked configuration; or o allow the removable support 12 to slide freely in a sliding configuration.

[0079] The method includes 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.

[0080] 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 hanging device and the removable support 12.

[0081] This method offers numerous advantages. It allows for the temporary removal of vegetation, either for plant maintenance or building upkeep. Furthermore, it eliminates the need for heavy machinery. Finally, the method can be implemented by a single operator. DESCRIPTION OF THE FIGURES

[0088] Figure 1 illustrates a green roof system. A growing tray is installed at the base of a high-rise building. Two anchors are provided on the growing tray, from which two cables extend. Each cable runs vertically to a coupling device fixed to the roof of the building. A trellis in the form of a textile net extends between the two cables. A birthwort (Aristolochia) grows by twining itself around the trellis. The coupling devices include fuses that can be activated simultaneously, causing the trellis and the birthwort growing on it to fall to the ground.

[0089] Therefore, if a fire breaks out in the building, the greening system can be very quickly removed from the building, which greatly reduces - or even eliminates - the risk of the fire spreading to the greening system.

[0090] Figure 2 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. The tensioning system is connected to a coupling device and a fuse. The fuse can be activated, causing the cable and the morning glory to fall to the ground.

[0091] On the left of figure 2, the cable is in a taut configuration: the cable is aligned with the facade and the plant is close to the facade.

[0092] To facilitate plant maintenance, the cable is slackened – to the right of Figure 2 – to switch to a relaxed configuration. 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.

[0093] Next, the cable will return to a taut configuration to replace the vegetation.

[0094] Figure 3 illustrates different removable greening devices for climbing plants on a high-rise building.

[0095] The arrangement shown in Figure 2 is repeated in the center of the building.

[0096] To the left of the building, a device consisting of a growing tray with two pegs attached is positioned on a balcony (freely accessible to pedestrians). A cable is attached to each peg, 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. Between the two cables extends a trellis in the form of a textile net with an average mesh size of 10 cm. A Dutchman's pipe (Aristolochia) grows by twining itself 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. Each tensioning system is equipped with a coupling device and a fuse.The fuses can be activated simultaneously, so as to cause the trellis and the aristolochia growing on the trellis to fall to the level of the balcony.

[0097] To the right of the building, a device consisting of a growing tray with two pegs 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. This pulley then 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 lower the trellis and the plant to the ground, and then tightened to reposition the trellis and the plant against the facade. Each of the tensioning devices includes a fuse. The fuses can be activated simultaneously, causing the trellis and the akebia growing on it to fall to the ground.

[0098] Figure 4 illustrates a multidirectional removable greening system on a high-rise building.

[0099] On the front facade, a device comprising a growing tray with two pegs is positioned on the ground. A cable is attached 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, forming a 30° angle with the vertical. The tensioning systems are equipped with electric winches, the one on the balcony being remotely controlled. Chinese blue vines (Holboellia coriace a. j(not shown) grow by twining around the cables. The two winches allow the cables to be slackened to lower the plants to the ground, and then tightened to reposition the plants on the facade. The overhead tensioning system and the return mechanism are each connected to a coupling device and a fuse. The fuses can be activated simultaneously, causing the cables and the Chinese blue vines growing on them to fall to the ground.

[0100] Figure 5 illustrates a removable greening system on a detached house.

[0101] A device comprising a growing tray with two pegs attached is installed under the overhang of a detached house. A cable is fixed to each peg, and each cable is engaged in a pulley (on the left) or two pulleys (on the right) located under the overhang. These pulleys direct the cable to a tensioning system 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 vine (Actinidia) grows by twining itself around the trellis. The two winches allow the cables to be slackened to lower the trellis and the vine to the ground, and then tightened to reposition the trellis and vine as a living screen. Each of the tensioning devices includes a fuse. The fuses can be activated simultaneously, causing the trellis and the kiwi growing on it to fall to the ground.

[0102] In other embodiments, illustrated for example in Figure 6, the removable vegetation system is placed in a parking lot so as to shade at least one parking space. To improve the readability of Figure 6, only the trellis 18 and the growing tray 20 are shown. In other words, the anchoring means 10, the removable support 12, the power supply system 14, the return means 16, and the building are omitted from Figure 6.

[0103] In some configurations, the trellis 18 may include at least one angle. For example, the trellis 18 may include a vertical section 181 and a horizontal section 182. The planting tray 20 may then be connected to the vertical section of the trellis 18, and the climbing plant grows from the planting tray 20 up the vertical section 181 of the trellis 18, and then up the horizontal section 182 of the trellis 18. The horizontal section 182 is then configured to shade the parking space. In other examples, the climbing plant may grow directly from the ground.
