Description

The present invention relates to a roofing element for roof mounting within a roof area of a building according to the preamble of patent claim 1.

However, such canopy elements are well known in the art. Particularly well known are such roof elements which are designed in the form of plates, these plates are at least partially radiation-transparent to visible light.

Through this translucency, the roofing element serves both as a roof protection (against rain, cold, etc.) and as a natural light source by illuminating the interior. The incident on the roofing element light falls namely on an outer wall of the roofing element and is at least partially transmitted through the radiation-transmissive material of the roofing element therethrough. The light entering through the roofing element again in the direction of an interior of a building can then illuminate and illuminate the entire building in a particularly homogeneous and natural manner.

However, the roofing elements known from the prior art have the disadvantage that they are supplied to no further purpose than a canopy and a Innener brightening. Up to now, no roofing element could offer the possibility of designing this in addition to the above-mentioned properties as such that at least one further useful function of the roofing element can still be perceived.

Proceeding from this, it is therefore an object of the present invention to provide a particularly cost-effective and individually usable roofing element for roof mounting within a roof area of a building, which has at least one other useful function in addition to a protective function and a lighting function.

This object is achieved by the subject of the protection claim 1. Advantageous embodiments are described in the dependent claims.

In order to now offer a low-cost and individually usable roofing element for roof mounting within a roof area of a building, which has at least one other useful function in addition to a protective function and a lighting function, the present invention makes use of, inter alia, the idea of at least one useful element, detachable or insoluble to arrange, wherein the Nutzelement occupies only a portion of the surface extent of the body in its main extension plane.

In other words, the useful element covers only a part of a space arranged in the direction of impact of the radiation behind the roofing element. At any time, the space of a building can still be perfectly lit up.

According to at least one embodiment, the roofing element for roof mounting within a roof area of a building comprises a base body, which in turn comprises at least one cavity, wherein the base body is at least partially transmissive to electromagnetic radiation in the visible or infrared wavelength range, wherein at least one useful element, detachable or insoluble, is arranged, and wherein the Nutzelement occupies only a portion of the surface extent of the body in its main extension plane.

In accordance with at least one embodiment, the useful element, in particular, is arranged completely within the cavity of the roofing element.

According to at least one embodiment, the base body comprises at least two hollow chambers, wherein at least one of the hollow chambers is free of the useful element, and the hollow chambers are separated from each other by at least one intermediate wall. For example, the main body comprises a plurality of hollow chamber, wherein only every second, third or fourth hollow chamber is empty.

In accordance with at least one embodiment, the useful element comprises at least one solar cell unit, the solar cell unit comprising at least one solar cell and at least one energy supply unit, wherein the energy supply unit is set up and provided for supplying the solar cell with electrical energy.

In accordance with at least one embodiment, the solar cell and a radiation-permeable part of a main body outer wall of the main body overlap one another in a direction transverse to the main extension direction of the main body so that the solar cell can be supplied with electromagnetic radiation through the main body outer wall.

According to at least one embodiment, the power supply unit and the Solar cell arranged in each case different hollow chambers.

In accordance with at least one embodiment, the useful element is a solar thermal or ceiling heating.

In principle, however, the following implementations are also conceivable:
The use of a hollow chamber for generating electricity via the solar cell is conceivable initially, wherein a lighting device, for example in the form of an LED panel, may be arranged on the main body outer wall and / or in a cavity itself.

In addition, can be accommodated within a hollow chamber batteries for power storage and control boards and control electronics as well, so that the entire solar cell unit can be additionally housed with the lighting device within the body.

Namely, the LEDs of the lighting device can be operated in the form of solar lights, the LED lights include additional radio or infrared switches or can be operated by such.

In this case, the batteries that at least partially fill a cavity, also provide the power for other consumers in different voltages.

In addition, it is conceivable that at least one hollow chamber is cooled by a ventilation system in order to increase the power of the solar cells. Namely, at high solar radiation, a temperature within the cavity can suddenly increase, so that thereby an efficiency of the solar cell can be impaired. The fan now ensures a preferably continuous time ventilation within the cavity. For example, the fan temperature and / or time and / or be controlled by daylight, so that it only starts when, for example, the sun is shining. In particular, the fan can be installed in the main body wall.

However, it is also conceivable - as already indicated above - that the solar cell is mounted not only in the cavity but also outside the cavity on a housing outer wall. Preferably, in the case of external mounting of the solar cell, the solar cells have an insulating protective layer, which may also be useful for other applications.

As an alternative to the use of the useful element as a solar cell - as already indicated above - the useful element can also be designed in the form of a solar thermal system. It is conceivable in this context that at least one (plastic) tube is arranged in at least one cavity, wherein through the (plastic) tube a liquid, preferably water is passed and heated so that the liquid heats when flowing to a predetermined circulation temperature. The heat can then be stored in a boiler via a heat exchanger.

Preferably, however, care is taken in such an embodiment that the liquid can cool, otherwise the system would overheat. An additional transparent insulating layer on a body outside can prevent the radiation to the outside, whereby an efficiency is increased. So if the liquid is blown into the tubes at night or with reduced radiation, thus increasing the insulating effect of the plate.

In addition, it is conceivable that the useful element is designed in the form of a ceiling heating.

Namely, if the above-described tube, preferably the above-described plastic tube, flows through hot water, the result is a ceiling heating. It is conceivable in this context, as well as in connection with the solar thermal, that not only a plastic tube is guided within the cavity, but within the cavity a plurality of plastic tubes is guided, which result in at least two layers of tubes. In this respect, this is a staggered arrangement of the tubes. If hot water is then passed through these tubes only within the tube position facing an interior of a building, then they form the interior of the building facing away from, thus the outside, d. H. Environment, facing plastic tubes an insulating layer, so that an insulating effect is created by these empty tubes, whereby radiation to the outside is reduced.

In addition, a use of the Nutzelementes and in particular of the body as a room cooling is possible. Namely, the tubes facing the interior can carry such a liquid which is cooled by a heat exchanger, while the upper, d. H. an environment facing tubes to be heated solar. Heating and cooling can therefore be optimized by using a heat pump.

All unused chambers can also be sprayed with dark colored liquid from the inside, d. H. be sprinkled starting from the cavity, wherein the then sprayed liquid can be collected in grooves and returned to a heat exchanger.

It is also conceivable that in a cavity in several places open tubes are formed or arranged, in which a copper wire is located (copper tubes can also be used). At the edges of the main body outer openings may be formed, wherein in an area of the central body of an inner opening is formed, on which the fan is arranged. When warmed indoor air passes through the cavity and out through the tubes, it heats the copper wires inside it.

If the fan is reversed or a second one is used, air is sucked in through the tubes from the outside, whereby it heats up over the copper wires. The fans preferably operate cyclically, once heated air is blown out and once cold air is sucked from the outside.

Likewise, use of the hollow chamber for air heating take place, in which case a hollow chamber is in turn filled with the tubes. In such an embodiment, it is conceivable that there is a free space within a central region and, for example, a plurality of free spaces at ends or corner regions of the cavity. Within this central area, a fan is attached to an opening of the central area inwardly in the housing wall again. On both sides open tubes, which lead to the free spaces at the edges, arranged, these tubes have, for example, an opening to the outside.

In sunlight, therefore, air is heated in the tubes and sucked inward. These fans can also be operated with solar cells. In particular, it is conceivable that this fan only runs when the sun is shining, so that no cold air can be sucked inwards.

There is also another application in the use of double-wall sheets for air conditioning and as a water / water heat exchanger. Consequently, therefore, the roofing element described here can generally be designed in the form of double-skin plates. A hot water tank can be located at the bottom of the room, leaving the room free.

In essence, therefore, as already stated above, a particular advantage of the invention is that many applications would be possible within a roof, without requiring additional space.

So no further devices for the production and storage of solar power are necessary. On a lighting device can be omitted. There is the possibility of solar water heating, room ventilation and interior air conditioning. In this case, an assembly by a plug-in system, with which the individual hollow chambers are connected to each other, particularly simple, so that the roofing element described here can be used everywhere, where previously also double-wall sheets are used. In other words, therefore, the solar energy can be used directly in a variety of ways.

In accordance with at least one embodiment, the energy supply unit comprises a battery device, wherein the battery device comprises at least two batteries connected in series, and the two batteries are connected to one another in an electrically conductive manner by means of an electrically conductive connection conducting element.

According to at least one embodiment, the Verbindungsleitelement comprises at least two connecting elements, which are arranged detachably, solder-free and non-jamming electrically conductive at two adjacent batteries, the Verbindungsleitelement each having a first pole of a battery having a second, a pole different polarity, pole of an adjacent battery electrically conductive connects.

According to at least one embodiment, the connecting element is only magnetically arranged on the batteries, and in particular their poles, and / or liable.

In accordance with at least one embodiment, the connecting element comprises at least one magnetic and / or magnetizable adhesive element.

In accordance with at least one embodiment, the attachment element is at least partially connected in an electrically conductive manner to a line element, and the line element is a part of the connection line element.

In accordance with at least one embodiment, the line element is formed with a copper. However, an electrically conductive adhesive or another electrically conductive metal, for example aluminum, may also be considered.

In accordance with at least one embodiment, power supply connections for supplying energy to the useful element and / or further elements (eg an LED panel) are connected without soldering to an outer and / or inner surface of the base body, and the line connections are formed with a copper.

However, an electrically conductive adhesive or another electrically conductive metal, for example aluminum, may also be considered.

In the following, the roofing element described here will be described in detail with reference to an embodiment and the associated figures.

In the 1 is shown with reference to a schematic plan view of an embodiment of a roofing element described here.

In the 2 is an embodiment of a Verbindungsleitelementes described here for electrically contacting a Nutzelementes in a possible embodiment described.

In the exemplary embodiments and in the figures, identical or equivalent components are each provided with the same reference numerals. The elements shown here are not to be considered as true to scale, but individual elements may be exaggerated to better understand.

In the 1 is a schematic plan view of an embodiment of a roofing element described here 100 shown for roof mounting within a roof area of a building.

In particular, the roofing element described here comprises 100 a basic body 1 which has a plurality of in a main direction of extension of the main body 1 arranged and in particular assembled cavities 11 includes. The main body and in particular the wall material of the main body 1 is at least partially permeable to electromagnetic radiation, so that in the case of assembly of the body on a roof, the daylight at least partially through the roofing element 100 can pass through and enter a room to illuminate an interior of a building daylight.

In particular, in 1 recognizable that within at least one of the hollow chambers 11 a useful element 2 is detachably arranged, so that the Nutzelement 2 For example, although a space of a cavity 11 completely filled, but the other cavities 11 free from the user element 2 are, so - though the useable element 2 within, preferably completely within the body 1 is arranged - still electromagnetic radiation through the roofing element 100 at least partially pass through.

In this respect, despite the beneficial element, it loses 2 the roofing element 100 nothing or essentially nothing of its dual function in terms of protection against environmental influences (rain, cold) and as a lighting function. It is only connected to at least a third or even more useful function.

In the present embodiment, therefore, the hollow chambers 11 through each intermediate walls 110 separated from each other and in particular in each case in the form of plug-together double-wall plates.

In addition, the useful element includes 2 in the 1 a solar cell unit 3 , wherein the solar cell unit 3 at least one solar cell 31 and at least one power supply unit 32 includes, wherein the power supply unit 32 is set up and intended to supply the solar cell with electrical energy.

The decisive factor is that the solar cell 31 which at least partially within a hollow body 11 of the basic body 1 is arranged, is sufficiently supplied with daylight.

For this purpose, preferably the main body outer wall 12 partially further preferably completely formed with an at least partially radiation-transparent material, so that - although the solar cell 31 in the cavity "hidden" is arranged - this is still sufficiently supplied with electrical energy.

In other words, therefore, an area of the solar cell overlap 31 with the main body outer wall 12 of the basic body 1 in a direction transverse to the main extension direction of the main body 1 at least in part, leaving the solar cell 31 through the main body outer wall 12 can be supplied with electromagnetic radiation.

In addition to in the 1 shown solar cell 31 includes the solar cell unit 3 Furthermore, a power supply unit 32 which of the solar cell 31 energetically fed. In other words, therefore, the solar cell 31 the power supply unit 32 to charge with electrical energy. Preferably, therefore, the solar cell unit 3 a full supply unit which stores electromagnetic radiation into electrical energy, in particular in the form of a battery.

Alternatively, however, comes an embodiment of the element 2 in the form of a solar thermal or a ceiling heating, etc. in question.

More specific to the embodiment of 1 and therefore includes - as already indicated above - the power supply unit 32 , a battery device 320 , wherein the battery device 320 at least two batteries connected in series 320A includes and the two batteries 320A by means of an electrically conductive Verbindungsleitelementes 321 electrically conductively connected to each other.

In particular, namely, the Verbindungsleitelement 321 with at least two connecting elements 321A educated. In other words, connects the Verbindungsleitelement 321 respectively adjacent poles of each, preferably directly, adjacent batteries, preferably also soldering and jamming.

It has been the experience that a soldering of the fasteners 321A with the individual poles of the battery is unnecessary. It is namely the roofing element 100 around a static element, so that the inventor has made the surprising experience that a preferably only magnetic connection of the Verbindungsleitelemente 321A with the respective poles such releasable, solderless and jam-free, in any case, non-destructive connection, with the poles of the batteries manufactures without an electrical contact is deteriorated.

For further improved releasable and non-destructive connection between the Verbindungsleitelement 321A with the poles of the respective batteries included in the embodiment of the 1 each connecting element 321A a magnetic and / or magnetizable adhesive element 321AB (see more detailed description in the 2 ).

As of the 2 can be recognized is the connecting element shown there 321A as already mentioned above, each with at least one adhesive element 321AB educated.

In particular, namely the adhesive element 321AB at least partially electrically conductive with a conduit element 321C connected, wherein the conduit element 321C a part of the Verbindungsleitelementes 321A is.

In particular, it may be at the line element 321C to a copper compound, in particular formed in elongated form act. The two attachment elements 321AB , which are preferably formed in the form of permanent magnets, are therefore by means of the conduit element 321C connected with each other.

In addition, moreover, is still in 1 recognizable that energy supply connections 4 starting from the solar cell 31 to the power supply device 32 lead. Crucial here is that the inventor has surprisingly recognized that the power supply connections 4 electrically conductive and contacting on respective contacts of the solar cell 31 merely pressed, preferably only need to be laminated. The connection is therefore, as indicated above, made solder-free. This also applies to such power supply connections 4 , which are formed with a copper.

In other words, it was particularly surprising for the inventor that - although such copper compounds are particularly suitable for solder joints - these can be particularly easily laminated or pressed and thus also such connection points between power supply connections 4 with the solar cell 31 or other energy supply or generation units can be solved without destruction and in particular are also connected without soldering and jamming.

The invention is not limited to the description with reference to the embodiment. On the contrary, the invention encompasses any novel feature as well as any combination of features, that is to say in particular any combination of features which comprise the claims, even if this feature itself is not explicitly stated in the patent claims or in the exemplary embodiment.
