Description

The present invention relates to a drive for movable building parts and building parts comprising a movable building part with such a drive.

Drives for moving parts of buildings are well known from the prior art, such as from the EP 1 921 242 ,

Such drives are usually connected to supply and control lines.

The object of the invention is to perform such drives in use more flexible and energy-efficient.

The object is achieved by a drive according to claim 1 and a building part according to claim 20. The dependent sub-claims 2 to 19 and 21 indicate advantageous developments.

An inventive drive for a building part according to the invention, in particular a pivotable ventilation element, a pivotable window, a hinged flap or a door or a swiveling flue has a drive element, a force transmission means and an energy store electrically connected to the drive element. In this case, the power transmission means is terminally connected to the movable building part or a building part, which rests upon movement of the movable building part, or connectable. Furthermore, the power transmission means is coupled to the drive element such that the drive element acts on the power transmission means. In this case, the drive element is in turn mounted in a housing which is connected or connectable to the building part, which rests upon movement of the movable building part, or with the movable building part. To connect, for example, a console can be used. Thus, by operating the drive element and by the mediation of the power transmission means force can be applied to a movable part of the building or force between a stationary and a moving building detail, thereby moving the movable part of the building. This makes it possible, for example, to open or close a window.

The drive according to the invention is characterized in that the energy store is arranged in the housing and that a solar module is provided which is tiltably, pivotably and / or movably connected to the housing. In this case, an electrical connection between the solar module and energy storage is provided and / or produced automatically by a drive control. The drive according to the invention thus has a solar module, which can be optimally aligned by tilting, swiveling and / or movable arrangement on the housing for solar radiation. As a result, the drive according to the invention with optimal use of solar energy can be placed comparatively freely. Advantageously, the drive has no further energy supply device, ie in particular no connection to other power sources. The energy storage ensures that the drive not only works with sufficient solar radiation, but energy can be cached, and thus a movement of the movable part of the building is guaranteed at present not sufficient solar radiation.

Optimally, the control of the drive is implemented so that opening the building parts or procedures from the rest or safety position is only possible or only as far as possible, as currently sufficient energy is present in the energy storage to safely close the movable part of the building can. This is useful, for example, in the case of movable building parts which are arranged so that they can rain into the building when the building parts are open, but more importantly, for example, in safety-relevant components such as smoke extractors, which are also partly used for ventilation.

By independently establishing the connection, for example, the manufacture by an integrated control electronics is conceivable, for example via relays. This is conceivable, for example, in the case in which the connection was interrupted due to lack of sunlight and the solar radiation again exceeds a planned minimum and thus a charging process of the energy storage is continued by the control electronics and automatically a connection between solar module and energy storage is made. It is also conceivable that the charge of the energy store is interrupted by an integrated control when it is completely filled and a connection is restored by the controller during or after appropriate discharge.

Advantageously, the drive has a spring and / or latching means, in particular a particular injection-molded plastic spring, which makes it possible to lock the solar module and / or prevents it from folding back or displacing the solar module due to gravity. Advantageously, the spring and / or locking means is designed so that the solar module can be easily folded, pivoted and / or tilted, for example, to be able to easily clean the corresponding window. Advantageously, a desired position of the solar module is adjustable, in which the Solar module can also be easily and reliably spent by non-specialist personnel.

Advantageously, the solar module is interchangeable, thereby the drive can be adapted for example to different parts of the building, in particular to different profile widths of stationary and / or moving parts of the building. In particular, various solar modules with different lengths, in particular laterally adjacent to a solar active surface, carriers are providable. Also, a removable solar module can be set up for separate mounting. For this example, corresponding consoles can be kept.

It is also advantageous to carry out an electrical connection between the housing and the solar module, especially in the case of exchangeable or separately mountable solar modules, for longer than necessary. This allows easy replacement and / or easy separate assembly. Advantageously, in particular in the housing, a memory for the use of the solar module on the housing excess electrical connection is provided. For this purpose, for example, be provided a retractor.

In one embodiment of the invention, however, the optionally replaceable solar modules are pivotally, tiltably and / or movably connected to the housing during operation or at least connectable.

The solar module advantageously has at least partially, in particular at least in the area of the solar active surface, a stabilizing profile and / or a frame, in particular a metallic profile and / or a metallic frame, in particular an aluminum profile and / or an aluminum frame, in order to prevent distortion of the solar module or counteract the solar active surface.

The energy storage advantageously has a low self-discharge and is particularly easy to replace. For this purpose, a, in particular snapped, energy storage compartment cover, in particular made of plastic, may be provided in the housing.

Advantageously, the solar module according to claim 2 has an axis parallel to the longitudinal axis of the housing about which the solar module is pivotable. Such an implementation as an at least tiltable solar module, in particular with an axis parallel to the longitudinal extension of the housing, has proved to be particularly solid and generally sufficiently flexible.

Advantageously, the axis is arranged according to claim 3 at one edge of the housing. This allows optimal space utilization and in particular a flat application of the solar module to the housing, resulting in a safe and space-saving transport and / or allows easy cleaning of the building part.

Advantageously, the housing has a passage for the power transmission means and the axis is arranged on the side of the housing on which the bushing is located. Such an arrangement has proven to be particularly advantageous. As a result, in particular an optimal solar yield can be realized with comparatively inconspicuous mounting. In general, an inventive drive is arranged so that the implementation is arranged on the side of the housing, which points in the direction of power transmission. In an arrangement of the drive to a stationary building part, the implementation usually has the moving part of the building, so for example in the direction of the window. If the axis is then arranged along the longitudinal extension and on the side on which the bushing is located, the solar module points in the direction of the window pane or of the movable building part, which leads to optimum utilization of the solar radiation.

Advantageously, the bushing is arranged centrally on the longitudinal extension of the housing. This is advantageous for a symmetrical power transmission, view and assembly.

Advantageously, the axis or the solar module is arranged so that it shows in the assembled state of the drive up and / or outside (relative to the building).

For this purpose, the implementation will usually be in the lower region of the housing and the axis usually in the upper region, in particular on the upper side, of the housing to be arranged.

Advantageously, the solar module according to claim 5 has an at least half-closed, at least one side open channel which extends at least partially around the axis. The electrical connection between energy storage and solar module runs at least partially through this channel. Under the electrical connection between energy storage and solar module and an electrical connection between solar module and board, which in turn is responsible for charging the energy storage or at least for charging the energy storage, is to be understood. It is thus sufficient that energy from the solar cell for charging the energy store via an electrical connection that extends at least partially through the channel.

By means of such a channel, which is open at least to one side, it is possible to carry out the electrical connection in a comparatively protected and inconspicuous manner and largely uninfluenced by the pivoting or tilting or method of the solar module. This ensures a safe electrical connection in a simple manner, even when pivoting or tilting or moving the solar module.

As a rule, the solar module in a pivotable embodiment will have two laterally arranged carriers which establish a connection between solar cells and axis. In such a case, the electrical connection advantageously runs through at least one of the carriers and the channel is advantageously part of such a carrier.

Advantageously, the housing has a housing recess which is arranged so that a guided through the open channel cable can enter through the housing recess in the housing.

Advantageously, the channel according to claim 6 extends at least 45 °, in particular by 90 °, about the axis. This allows a correspondingly wide tilting with hidden and largely uninfluenced electrical connection. In general, it is sufficient to make the solar module tiltable by 45 ° to 90 °, so that a channel which extends by 45 ° to 90 °, in particular by 90 °, about the axis, is usually sufficient.

In this case, a channel which is at least half-closed and open at least to one side is to be understood as meaning a channel which surrounds the electrical connection at least on two sides. Advantageously, however, it surrounds the connection on three sides and is therefore only open to one side. This can be ensured for example by a semicircular in cross-section or U-shaped channel.

For example, it would also be conceivable to have a semicircular cross-section channel.

Advantageously, the channel is arranged according to claim 7 on one side of the solar module. This is the case, for example, if the solar module has carriers on both sides and the channel is arranged in one of the carriers.

Advantageously, the housing has at least one housing recess, through which the axis runs. Thus, the axis or the connecting elements of the solar module, for example, the mentioned lateral support can be arranged so that they do not stand beyond the outer shape of the housing, but rather are each received in a recess. This does not mean that the carriers are taken up in their entirety in the recess, but that at least the parts that surround the axis are recorded there. Such a support may for example be L-shaped, with the axis passing through the end of the short leg of the L, so that, for example, the short leg of the L could be received at least in part or for the most part in such a recess.

Advantageously, the housing has a housing opening designed as a cable opening, which ends in a housing recess, through which the axis extends and in which the channel is at least partially accommodated. Such a design allows a concealed and secure guiding of the connecting cable and can be realized in a simple manner and inexpensively.

Through the channel and in particular through the housing recess, a flexible cable is advantageously guided, which has at least two, in particular exactly two, or at least one conductor when using several cables. When using two carriers both carriers can have such a channel and can be provided corresponding to two housing recesses matching the channels. Then it is sufficient to lay through each channel a flexible cable with at least one conductor.

Advantageously, the housing recesses are arranged according to claim 9 each on a housing edge. With particular advantage, the at least one housing recess is arranged on a housing corner. With particular advantage, the housing has two housing recesses arranged on housing corners, in particular opposite housing corners, which are arranged along a housing longitudinal side.

Such housing recesses are particularly easy to manufacture and, for example, allow an arrangement of the axis described above on a housing edge.

Advantageously, the solar module or the housing is designed so that the solar module in at least one position on the back flat against the housing, in particular at its top. When back concerns is such a concern to understand in which the solar cells of the solar module continue to point outward and can be illuminated by sunlight. Such an arrangement, in which the solar module is hinged, allows easy and reliable and space-saving transport.

Advantageously, according to claim 11, the power transmission means is a chain. Chains have proven particularly useful for power transmission between building parts.

Advantageously, the housing includes a guide and / or a memory for the power transmission means. This allows a recording of the power transmission means, unless it is for power transmission outside of the housing. This allows protection of the power transmission means.

Advantageously, the housing includes a control electronics. The arranged within the housing control electronics allows easy installation and possibly a self-sufficient drive. Advantageously, the control electronics includes a controller, in particular μ-controller. Advantageously, the control electronics safety functions, such as switching off and opening at obstacles, control and safety shutdown in tandem operation at least two drives on a movable part of the building or others realized.

Advantageously, the housing has an interface for connection to at least one drive unit. Such an interface, which is part of the housing may be, for example, a plug connection or an antenna. In this case, the interface can be set up, for example, to receive control commands and / or to transmit status messages and / or to provide (additional) electrical power.

Advantageously, the drive has a wireless interface for receiving control data and / or delivery of status data. With particular advantage, the drive beyond, if necessary, apart from wireless interfaces, no further interfaces, in particular, does not rely on the connection via other interfaces. Advantageously, in a wireless interface, the housing has a plastic-made area behind which advantageously the receiving and / or emitting device is located directly. In particular, two plastic areas, one provided as Akkufachdeckel and one in the area of the transmitting and / or receiving device.

Advantageously, the solar module includes at least one, but usually several, solar cells.

Advantageously, the housing on at least two side surfaces at least one mounting hole, which is arranged parallel to the axis. This allows a particularly flexible and space-saving installation, for example on U-shaped consoles.

With particular advantage, the mounting holes have at least partially threaded, so that screws can be screwed.

Advantageously, the holes are located on the side of the housing on which the axis is located, but on another edge of the housing. Thus, particularly advantageously, the axis between two upper corners of the housing, in particular along a longitudinal edge, be arranged, while the bores could be at least partially disposed on further, respectively adjacent corner of the housing. Advantageously, in such a case, the bushing is arranged on the side surface, which is arranged between the corners between which the axis and at which the bores are arranged. This is advantageously a narrow longitudinal side of the housing.

Advantageously, the drive, in particular the housing has at least one optical display means, in particular at least one LED, in particular two-color LED for signaling operating states. For example, the state of charge of the energy store, closed due to rain and / or 10-minute ventilation.

The object is also achieved by a building part comprising a movable building part, in particular a pivotable ventilation element, a hinged flap or a door or a swiveling flue, comprising a drive element according to one of the preceding claims. In such a building part may be, for example, a window frame with casement. The drive can be fastened, for example, on the window frame, while the power transmission means is connected to the window sash. An inverted arrangement is also conceivable.

Advantageously, the housing is adapted so that the solar module can be arranged so that the solar active surfaces adjacent to a profile of the movable building part, such as the sash, and are only covered by glass. Such an arrangement, in which the solar active surfaces, for example, adjacent to the inner edge of the sash profile, allows a particularly space-saving arrangement, but ensures the most effective use of solar active surfaces.

Further advantageous embodiments are to be illustrated purely by way of example and not by way of limitation with reference to the following purely schematic sketches.
