Description

The invention relates to a porch device for fastening in the area of an external opening of a building, in particular a window opening, the porch device being a trough-shaped container with an opening pointing upwards, a first longitudinal wall which points towards the building when the porch device is in the fastened state, a further longitudinal wall and two Having side walls, and wherein the container at its first

Longitudinal wall can be arranged on the building.

External shading and greening are - apart from building insulation - the two most effective measures for reducing energy requirements and increasing the climate comfort of buildings

at high outside temperatures or intense sunlight.

Various concepts are available for implementing these measures in existing buildings, i.e. for subsequently improving the energy efficiency or the indoor climate of a building, with many of these concepts being based on the subsequent greening and shading of building openings, such as openings

for windows, balconies or loggias.

For many years it has been customary to provide plants on the outside of existing buildings, especially in the area of windows or balconies, since they have a clearly measurable effect on the microclimate surrounding them. The plants not only protect the building from direct sunlight, but also cool their immediate surroundings, for example by evaporating water. As a result, the outside air flowing in through the building opening and the building as a whole

chilled

For example, front construction devices for building openings are known from WO 2019/137063, in which several plant containers with climbing aids are arranged in front of the building opening. The

Plant containers can be swiveled around a vertical axis,

depending on the degree of pivoting of the plant containers, more or less light reaches the plants growing on the climbing aids

can enter the building.

It is also known in existing buildings inside or outside of windows or balcony doors subsequently shading or. Install blackout elements to reduce the amount of light entering the building. This lowers the room temperature and possibly also the energy costs of the cooling systems in the building, such as air conditioning. For example, shading or darkening elements such as roller blinds, awnings or venetian blinds that are adjustable in their effective length, but also rigid or merely pivotable elements that absorb part of the incident sunlight are used

or should reflect used.

From CN 11194623 A is a stem device for arrangement

a window opening is known which has photovoltaic elements.

A disadvantage of the known solutions for shading or darkening building openings is that they only focus on certain aspects and therefore cannot adequately utilize the advantages that only arise through a combination of shading and greening. If, for example, plant containers are subsequently attached to building openings, the plants growing in them obstruct shading elements subsequently mounted on the building and vice versa. Furthermore, the solutions available on the market are usually strongly adapted to certain initial situations regarding the space available or the design of the building envelope and to existing ones

Buildings can only be "upgraded" with great expenditure of time and money.

The invention is based on the object, a

Stem device of the type mentioned are available

to face the disadvantages of the prior art

having. In particular, a porch device is to be provided, with the help of which the advantages of shading and greening can be combined in the simplest possible way. The porch device according to the invention is intended to create the possibility of gaining additional shaded and usable space in existing houses. A further object of the invention is to provide a front-mounted device that can be integrated as universally, easily and quickly as possible into existing building shells and is therefore ideal for energy and room climate technology

improvement of existing buildings.

This object is achieved according to the invention with a

Front end device having the features of claim 1.

Preferred and advantageous embodiments of the invention are

subject matter of the dependent claims.

According to the invention, it is provided that at least two carrier elements are arranged with a first end on the further longitudinal wall and/or one side wall each, that the carrier elements are inclined at an angle <90° from the container in the direction away from the further longitudinal wall and towards the first longitudinal wall protrude above, and that a shading element is arranged on the support elements, which is substantially parallel to the support elements in the direction of the container in its

effective length is adjustable.

The trough-shaped container of the stem device according to the invention is suitable for receiving plants, the plants directly in the container or in at least one im

Container arranged inner container can be planted.

The support elements extend from the opening of the container

and from that longitudinal wall of the container, which is attached to

Stem device is not mounted on the building, and / or away from the side walls obliquely upwards, so that they preferably up to the front-end device attached to the building

Extend building wall or outside opening of the building.

It is particularly preferred if the carrier elements are arranged, in particular fastened or mounted, with their first ends directly on the further longitudinal wall or in each case on a side wall, preferably in the region of the further longitudinal wall. However, they can also be connected to the container with their first ends via a connecting element or connecting elements, such as a lattice, a frame construction, a linkage, etc

to be connected.

The shading element occupies an area that casts a shadow on areas below, behind and/or next to it when the sun is shining and can be referred to as an effective area. The length of this effective surface can be changed, depending on how far the shading element is adjusted (for example extended, unfolded, pivoted, etc.), and is referred to as the effective length of the shading element. The shading element is arranged on the support elements, i.e. on both support elements, and its effective length can be adjusted parallel to them. The shading element (and thus the effective area) is preferably essentially as wide as or wider than the area spanned between the carriers and is located in this area or

offset below or above.

Due to the oblique course of the support elements, a useful volume is created between the support elements and the opening of the container, which can be used by plants, for example, without the shading element being displaced in its effective length in the direction of the container.

block or be damaged by this.

Even if plants are preferably planted in the container of the porch device according to the invention in order to be able to combine the advantages of shading and greening, the usable volume can also be used in other ways and in any case provides an additional space adjoining the building that provides shade (i.e. fully or partially protected from solar radiation). This space can be used, for example, as seating or storage space, i.

generally used as an extension of living space.

In particular, within the scope of the invention, an embodiment is preferred in which guide elements for laterally guiding the shading element are arranged on the carrier elements. These guide elements can preferably be guide rails which are arranged opposite one another on the insides of the carriers, or on the sides of the carriers which point upwards or downwards. Within the scope of the invention, however, the guide elements can also be strips, cords, ropes, carriages, etc. When adjusting its effective length, the shading element is preferably parallel to the supports, at least in the region of its end closest to the container in or

on the guide elements.

In a preferred embodiment, the shading element can also be adjusted in length essentially perpendicularly in the direction of the container. For example, if the shading element has guide elements for guiding in a direction parallel to the support elements, i.e. in an oblique direction, it can be decoupled from the guide elements if necessary, so that in the decoupled state it is pulled down by gravity when its effective length is adjusted . The effective surface of the shading element, which is length-adjusted essentially perpendicularly in the direction of the container, also extends essentially

plumb.

It is preferred if the shading element is essentially based on the other (upper) ends of the support elements, i.e. the ends not arranged in the area of the container, or an area of the support elements which is arranged in the area of an upper edge of the building opening when the front building device is attached. is adjustable towards the container in its effective length. The shading element can also be arranged on the carrier elements at a distance from the further (upper) ends of the carrier elements projecting away from the container. Preferably, the shading element or the effective plane of the shading element essentially borders on an imaginary, vertical plane at the top

Extension of the first longitudinal wall that can be attached to the building.

Embodiments are preferred in which the carrier elements project upwards from the container at an angle of between 45° and 88°, preferably between 55° and 85°, in particular between 65° and 83°. It is thus ensured with the front-mounted device according to the invention that the usable volume formed between the support elements and the opening of the container largely has a relatively large height, so that plants with a higher growth can also be planted in the container without parts of them getting in contact with the

shading element collide.

Within the scope of the invention it can be provided that the longitudinal walls at the opening are at least 80 cm long and/or that the side walls at the opening are at most 50 cm long. Such dimensions ensure the largest possible usable volume or as much space as possible to plant plants or for other uses, but at the same time reduce the

Shadow cast by the porch device downwards.

Another possibility, the shadow cast by the porch

consists in aligning the other longitudinal wall of the trough-shaped container that is not attached to the building at an angle, so that it points away from the opening of the container and downwards

runs obliquely in the direction of the first longitudinal wall.

In particular, an embodiment is preferred within the scope of the invention in which the trough-shaped container has fastening means via which or with the aid of which it can be mounted on the outer wall of the building. The container can have through holes, for example, through which it can be screwed or hung on the outside wall of the building with screws or wall anchors. It is also conceivable that the container has clamping or spreading means in order to hold it in the building opening, for example in the window reveal

Window opening to jam or spread.

Embodiments are preferred in which the shading element has a fabric, net, tarpaulin or film that can be rolled out and rolled up or folded out and in. It is also possible within the scope of the invention for the shading element to have plate, bar or lamella elements that can be rolled out and rolled in or folded out and in or pivoted. Such shading elements are particularly effectively adjustable in their effective length, since they can be extended, rolled out, unfolded, unfolded or pivoted from a retracted, rolled up, collapsed, folded or pivoted state in which they have a very limited effective area, so that they Have a multiple, for example more than 3 times, preferably more than 5 times, in particular more than 10 times, the original effective length or effective area. The shading element with its rolled-up or folded-in components is arranged in particular at the ends of the support elements that are not in the area of the container

are arranged so that it is from one support member to the other

runs and extended in the direction of the container,

can be unfolded, rolled out, etc.

For example, the shading element can be an awning with a fabric or a net that can be rolled out and rolled in or out and folded in, a roller shutter that can be rolled out and in or out

be pivotable or off and foldable blind.

In an advantageous embodiment it is provided that the front-end device has a photovoltaic device for generating electrical energy and an energy store for storing the generated electrical energy. The energy store can preferably have one or more accumulators. The photovoltaic device with its solar cells and/or the energy store can be arranged directly on or in the support elements, the shading element or the container or as a separate conductor with the rest via (each) one conductor

Stem device connected unit / s be provided.

If the shading element has a housing, for example, the energy store can be arranged in the housing. It is also conceivable that the energy store is arranged in the container, for example on the bottom of the container or on one of the longitudinal walls or the side walls. In embodiments in which at least one inner container is arranged in the container, the energy store can be in the inner container or between the inner container and the container, for example in the bottom area or in the area of a

Longitudinal or side wall to be arranged.

In particular, embodiments are preferred in which the shading element serves as a photovoltaic device or the photovoltaic device is arranged at least in regions on the shading element. The photovoltaic device

(i.e. solar cells of the photovoltaic device) can be so am

Be arranged shading element that it covers part of the effective surface of the shading element. For example, in the case of a shading element which is designed as an awning, roller shutter or blind and has a housing, the photovoltaic device can be arranged on the outside of this housing. Within the scope of the invention, however, embodiments are also conceivable in which the photovoltaic device itself forms the shading element or a part or parts of the shading element. In such embodiments, for example, by adjusting the effective length of the shading element, the length of the working surface of the photovoltaic device, i.e. the surface that is equipped with solar cells for converting solar energy into electrical energy, can be adjusted in the direction towards the opening of the container and the working surface can thus be enlarged . In embodiments in which the shading element is a roller shutter or a blind, solar cells of the photovoltaic device can be arranged, for example, on the individual roller shutter rods or slats. In embodiments in which the shading element is an awning, solar cells can be arranged, for example, on the rollable or unfoldable fabric or net of the awning or the rollable or unfoldable tarpaulin of the awning can be a flexible photovoltaic element or a flexible

be a photovoltaic device.

Also conceivable within the scope of the invention are combinations in which, for example, part of the photovoltaic device is arranged on the other ends of the support elements, preferably on a housing of the shading element, and another, in particular larger, part of the photovoltaic device on the rollable, foldable, foldable, etc. part of

Shading element is arranged.

In the context of the invention it can be provided that the

Stem device has a control unit. With the help of such a control unit, different electrical and electronic subsystems that can be part of the front-end device can be controlled, monitored and regulated. The front-mounted device can thus also become a smart home device

In embodiments in which the front-end device has its own energy store, the control unit can preferably be supplied with energy by the energy store. Alternatively or additionally, however, the control unit can be connected to the power supply system of the building on which the front-mounted device is arranged

is to be connected.

The control unit preferably has a communication interface via which an input device, in particular a smartphone, can be connected to the control unit with the aid of a plug connection and/or wirelessly. The communication interface can be connected to the input device via Bluetooth, for example. However, it is also conceivable for the communication interface to be connected to the Internet via W-LAN or a network cable and via a router, a modem or directly. In this case, a suitable end device that can be connected to the Internet, such as a smartphone, a laptop or a PC, can be used as the input device. For the input device, there is in particular an application for accessing the controller and for executing the

Control controlled functions available.

If several front-end devices are arranged on a building, they can also be supplied with energy by a common energy store and/or be controlled by a common controller. In the context of the invention, the common energy store or the common control unit is also used

Viewed part of the stem device according to the invention.

It is particularly preferred if the shading element is connected to an electric drive for adjusting the length. For example, a shading element designed as an awning, roller shutter or blind can have at least one electric motor, by which the awning, roller shutter or blind is extended, unfolded, rolled out, pivoted, etc. An electric drive saves time and energy and - should it be provided in combination with a control - can also be activated if there is no person on site who is able to do so

to adjust the effective length of the shading element.

In embodiments of the front-end device that have their own energy store, the electric drive can preferably be supplied with energy by the energy store. However, the electric drive can alternatively or additionally with the power supply of the building on which the

Stem device is arranged to be connected.

It is also conceivable that the effective length of the shading element can alternatively or additionally be adjusted mechanically via a manual drive mechanism, such as a crank mechanism, or a belt pull. Such a drive system is less

prone to failure and requires less maintenance.

The shading element of the porch device according to the invention can be adjustable in length via an electric drive or a mechanical drive. In addition to or instead of this, the effective length of the shading element in embodiments that have the control unit can also

be automatically adjustable via the control unit.

In the context of the invention, the shading element in

be partially transparent. An opaque one

The shading element has, for example, an opaque fabric or opaque panel elements (rods or slats). A partially transparent shading element has, for example, a coarse fabric, a coarse mesh or plate elements (rods or slats) that are slightly spaced apart from one another. It is also possible that the shading element consists of a partially transparent film or tarpaulin or has or consists of partially transparent elements. In such embodiments, the property of opacity or partial transparency or partial transparency can apply to the entire shading element or only to a section of the shading element. For example, in a designed as a roller shutter shading element of the roller shutter box or the rolled part of the shading element opaque and the

rolled up section to be translucent.

It is also conceivable within the scope of the invention for the light transmission of the shading element—or at least parts of the shading element—to be variable. For example, the slats of a shading element designed as a venetian blind can be pivotable, so that the effective area of the shading element that casts shadows can only be enlarged or reduced by pivoting the slats. Within the scope of the invention, such a pivoting of slats, through which the effective area is increased, is considered to be an adjustment of the effective length of the shading element

viewed.

In the context of the invention, embodiments are preferred in which the trough-shaped container is watertight over the entire height. This allows for watering of plants received in the container and storing water for such plants in the container without water spilling down

drains. In principle, however, it is enough if only the lower part

of the container is watertight, so that embodiments within the scope of the invention are also possible in which the container has a height of at least 25%, preferably at least 75%

3, is waterproof towards the opening.

Alternatively or additionally, the container can have at least one watertight inner container or at least one such inner container can be arranged in the container. Such an inner container, which preferably extends at least as far as the opening, can also have the function of a

meet water retention requirements.

An irrigation system and/or at least one moisture sensor can be arranged in the container (or in the inner container). The irrigation system serves to deliver water in a predetermined amount to the container or inner container and thus to the plants contained therein. The sensor can be used to measure how high the water level is in the container or inner container or how high the water content of the substrate contained in the container or inner container is. For better monitoring, several sensors can also be integrated

be arranged the container or inner container.

If the front-end device according to the invention is connected to a common control unit or has a control unit, the irrigation system and/or the moisture sensor or moisture sensors is/are preferably connected to the control unit. This allows watering to occur according to a preset schedule or even directly in response to data collected by the moisture sensor(s). If the control unit is connected to a communication interface,

Irrigation commands are entered via an input device.

In addition to the irrigation system or instead, a water reservoir can be formed in the container, in particular in the floor area. For example, the container can be a type of double bottom or a substantially closed compartment arranged on the bottom or on a longitudinal or side wall.

In embodiments of the front-end device that have both an irrigation system and a water reservoir, the irrigation system can be fed from the water reservoir. In combination with a moisture sensor and a control, plants accommodated in the container can be optimally and without

Work effort to be supplied with water.

In one possible embodiment, the porch device has, in addition to the shading element, a transparent or partially transparent pane or film running from one carrier element to the other. Such a disk or foil can extend, for example, from the ends of the carrier elements that are not arranged in the region of the container to the container. This prevents living beings or objects from penetrating into the useful volume between the carrier elements or from being able to leave the useful volume between the carrier elements. Instead of the pane or film, a net or grid can also be provided, with such a net or grid--depending on the size of the gaps or meshes--being able to be penetrated by smaller creatures such as insects or smaller objects such as raindrops. The shading element can be arranged above (in front of) or below (behind) the pane, the foil, the network or the grid and in its

effective length adjustable.

Embodiments are also possible in which the projecting device has transparent or partially transparent panes, foils, nets or grids running from the carrier elements to the side surfaces of the trough-shaped container positioned underneath. These essentially fulfill the same purpose as a pane, a film, a net or a grid between the support elements and prevent living beings or objects (at least from a certain size) from penetrating the useful volume laterally or

can leave this sideways.

Within the scope of the invention, embodiments are possible in which the entire usable volume is closed to the outside. For example, discs can be arranged between the carrier elements up to the container and between the carrier elements and the longitudinal walls, so that the usable volume as a kind

Conservatory can be used.

It is also conceivable to integrate at least one lighting element into the front-mounted device according to the invention. If necessary, this lighting element can be connected to the energy store and/or the controller. The lighting element can serve to illuminate the usable volume and/or also emit or emit light in the UV range for the cultivation and care of plants.

The porch device 1 has a trough-shaped container 4 which, in the embodiment shown, has a first longitudinal wall 5 which is arranged on the building 3 , a further longitudinal wall 6 , two side walls 7 and a floor 8 . Upper edges of the longitudinal walls 5, 6 and the side walls 7 form

an upwardly directed opening 9 of the container 4. In the illustrated embodiment, the further longitudinal wall is 6

not parallel to the first longitudinal wall 5 or to the outer wall 10 of the

Building 3 aligned, but runs diagonally from the opening

9 way down and in the direction of the first longitudinal wall 5 or building

5.

The container 4 is arranged below the window opening 2 when it is mounted on the building 3 . It is connected to its first longitudinal wall 5 via fastening means 11, e.g. screws

or wall anchors, connected to the outer wall 10 of the building 3.

Two carrier elements 12, which in the illustrated embodiment are in the form of elongate carriers which are rectangular in cross-section, each have a first end 13 at one between the respective side wall 7 and the further longitudinal wall

6 of the container 4 formed corner connected.

The carrier elements 12 run obliquely away from the container 4 or the opening 9 and upwards and in the direction of the first longitudinal wall 5 or an imaginary vertical plane in which the first longitudinal wall 5 is arranged. In doing so, they enclose an angle x of less than 90°, the angle α being approximately 75° in the illustrated embodiment. The support elements 12 extend in the direction of the outer wall 10 of the building 3 and preferably run in the assembled state of the front-end device 1

substantially up to the outer wall 10 of the building 3 out.

In the illustrated embodiment, the container 4 is connected via additional frame elements 14 to the further ends 15 of the carrier elements 12, i.e. those ends 15 which are not arranged on the container 4. The frame members 14 are ]-shaped (i.e., square bracket-shaped) in the illustrated embodiment and are slidable into the window opening 2 . The front-end device 1 according to the invention can also be designed without frame elements 14, in which case the further ends 15 of the support elements 12 in

Essentially free from the container 4 protrude away.

A shading element 16 is arranged on the support elements 12, the effective length L of which, i.e. the length of the surface of the shading element 16 referred to as the effective surface W, which casts a shadow when the sun is shining, can be extended essentially parallel to the support elements 12 and in the direction of the container 4 . In the illustrated embodiment, the shading element 16 is an awning with a partially translucent fabric web 17 that can be rolled up and down on a roller 18 . By unrolling the awning or the web of fabric 17 of the shading element 16, the effective length L of the shading element 16 can be extended and

same extent, the effective area W can be enlarged.

In the embodiment shown, the shading element 16 is arranged in the area of the further ends 15 of the carrier elements 12 . In the case of the porch device 1 arranged on the window opening 2 , the shading element 16 is positioned in particular in the area of an upper edge of the window opening 2 and the outer wall 10 of the building 3 and can be extended in its effective length L in the direction of the container 4 . This means that the effective surface W of the shading element 16, which increases or decreases to the same extent by adjusting the effective length L of the shading element 16, preferably essentially on the outer wall 10 of the building 3

connects.

The support elements 12 and the opening 9 of the container 4 (or the container 4 itself) delimit a space that can be referred to as the useful volume N. Plants can be planted or objects positioned in this usable volume N. People or pets can also stay in it. In any case, the usable volume N is a usable space that is created by the porch device 1 and can be shaded by the shading element 16, i.e. completely or partially in front of

Sun exposure is protectable.

In the container 4, a waterproof inner container 19 is arranged, in which a substrate can be filled and not

plants shown can be planted.

In the illustrated embodiment, the walls 5, 6, 7 and the bottom 8 of the container 4 are formed from a perforated metal sheet and are therefore permeable to water. However, it is also conceivable for the walls of the container 4 to be watertight, starting from the base 8 over part of the height of the container 4 or even over the entire height of the container 4 . In such embodiments

no inner container 19 is required to accommodate plants.

In the embodiment according to FIG. 1, the roller 18 of the shading element 16 is arranged so that it can rotate between the carrier elements 12 . The web of fabric 17 shown as a shading element 16 of an awning is arranged at least in regions on or in two laterally on the carrier elements 12

The shading element 16 can also be decoupled from the guide elements 20 and then hangs essentially vertically downwards due to the force of gravity. In this decoupled state, the effective length L of the shading element 19 does not run parallel to the support elements 12, but can be adjusted in the vertical direction. The shading element 16 in the decoupled state is indicated in FIG.

implied.

As shown in simplified form in FIG. 2 , the front-end device 1 can have a photovoltaic device 21 which, for example, has solar cells 22 which are arranged on the shading element 16 . The

Photovoltaic device 21 is equipped with an energy store 23

connected, the gained via the photovoltaic device,

can store electrical energy.

In the embodiment shown in FIG. 2, the energy store 23 is arranged in the container 4 between the base 8 of the container 4 and the inner container 19. However, it is also possible for the energy store 23 to be located between one of the longitudinal walls 5, 6 or one of the side walls 7 and the inner container 19, on the shading element 16 or at another suitable position of the front-mounted device, or at a distance from the front-mounted device 1 (e.g. inside the

Building 3), is arranged.

The electrical energy from the energy store 23 is used, for example, to drive an electrical drive 24 of the shading element 16, with which its effective length L can be automatically adjusted. In the illustrated embodiment, for example, the roller 18 of the awning can be rotated by the electric drive 24 so that the

Fabric web 17 is automatically rolled up and down.
