EP2933418B2 - Frame for a window or door with electrical wires - Google Patents

Description

The invention relates to a frame for a window or a door, which comprises a fixed frame and possibly a sash frame that is movable relative thereto, the frame and / or the sash frame being composed of a plurality of hollow chamber profiles or solid profiles, at least one of the hollow chamber profiles being in one of its chambers or has at least one electrical conductor on its outer circumference or one of the full profiles in a machined groove or on its outer circumference, the conductor being connectable to a data processing device via a frame-side interface and to a sensor and / or actuator, and wherein the conductor is arranged in a ring or star shape in the frame and connected to the interface.

In practice, such frames are often assembled from hollow chamber profiles which are made of aluminum, plastic or a combination of these materials and, during their production, are equipped with sensors and / or actuators depending on the wishes or requirements of an end customer, to whom safety and / or or air conditioning relevance or which are necessary to support comfort functions. A frame for a new window or door can usually be fitted at the factory. A later adjustment is almost impossible or can only be realized with solutions that have an optically disruptive effect on the frame, for example the sensors / actuators are screwed onto the frame. Comfortable aids, such as intelligently controlled window ventilators or concealed motors with assigned gearboxes, can generally not be retrofitted into an existing frame. The installation of such actuators is usually associated with the installation of a new window or a new door. Precautionary installation of any number of different sensors or actuators is also not a solution, since these components are often relatively expensive and the standard home automation systems are not subject to any communication standards, which is why the relevant requirements cannot be specified.

A full profile can be made of wood, for example. The use of full profiles made of wood is useful partly for structural reasons and partly for visual reasons.

The DE 20 2010 014 775 U1 discloses a window or a door of a building according to the preamble of claim 1, wherein at least one electrical or electronic component for operating a PV module is arranged in the frame of a glass element of the window or door and / or in the frame of the window or door leaf is. To accommodate the corresponding components, the frame or the frame has at least one chamber that is part of the profiling of the hollow profile. The component has a connector module, a corresponding connector module being provided in the chamber and contacting the two connector modules with one another when the component is inserted into the chamber. In order to dissipate the electrical energy generated by the PV module, a cable is provided in the transition from the sash to the frame, which is subsequently guided by a hinge. For the transmission of data from and to the component designed as a communication device, the hinge or a metal frame or frame is designed as an antenna.

Furthermore, the DE 10 2005 004 505 A1 a door device with a door consisting of at least one door leaf and a door leaf frame and with a door holder on which the door is movably mounted. The door leaf frame surrounds the door leaf at least in some areas, the profile-like frame having at least one channel-like receptacle which extends to the side adjacent to the door holder. A cable, in particular a power supply cable and / or a data transmission cable, is provided in the interior of the receptacle, and control electronics and / or a lighting device is associated with the receptacle, at least on the end face facing away from the door holder.

Furthermore, the DE 203 03 946 U1 a door frame on which at least one electrical installation device is attached, or which has at least one receiving device for an electrical installation device. The electrical installation device is an electrical sub-distribution box, a socket or a light switch or an access point for a wireless network connection.

The invention has for its object to provide a frame of the type mentioned, which is individually functional expandable or changeable in the installed state.

According to the invention, the object is achieved by the features of the independent claim.

The subclaims represent advantageous embodiments of the invention.

A frame for a window or a door comprises a fixed window frame and, if necessary, a sash frame that can be moved relative to it, the window frame and / or the window frame being composed of a plurality of hollow chamber profiles or solid profiles, at least one of the hollow chamber profiles in one of its chambers or on its outer circumference or one of the full profiles in a machined groove or on its outer circumference has at least one electrical conductor at the factory, the conductor being connectable to a data processing device via a frame-side interface and to a sensor and / or actuator, and the conductor being ring-shaped or arranged in a star shape in the frame and connected to the interface. The conductor comprises several current paths / wires and lines, of which at least two current paths / wires serve for power supply and other lines are assigned to a data bus, and the sensors and / or actuators can be retrofitted, so their installation is possible if the casement is already assigned to a building as intended.

By installing the at least one conductor, which is designed, for example, as a single or multi-core cable, a printed circuit or conductor tracks integrated in the hollow chamber profile, any electrical / electronic sensors and / or actuators can be installed, even after the frame has been installed, So also possible depending on subsequent requirements, since the electrical / electronic sensors and / or actuators that are mechanically connected to the frame are electrically and / or data-technically connected to the frame-side interface via the electrical conductor and, for example, to a data processing device via the interface are connecting. The data processing device can be, for example, a mobile device, for example a laptop, a smartphone, a tablet or the like computer, or a personal computer or a server or a home automation device or the like. If the frame holds a filling or holds cover layers, it is of course possible to route the electrical conductor through a hollow chamber profile and the filling. If the frame holds at least one glass pane, then the conductor is preferably guided through the hollow chamber profiles in order not to have an optically disruptive effect.

The conductor is applied directly to the hollow chamber profiles or solid profiles. This application can go hand in hand with the production of the different hollow chamber profiles or solid profiles, so that the semifinished product for the frame is already provided with at least one conductor, which as a partial electrically conductive layer forming the conductor, which is produced in particular using thin-film technology. Such methods for applying conductors in mutually spaced paths to a hollow chamber profile or solid profile are known to the person skilled in the art. The outer circumference of the hollow chamber profiles or solid profiles does not mean the outside of the window or door. The conductor can be applied at any point on the hollow profile or solid profile, for example also in a fold, so that it is not visible to an observer of the finished frame.

The conductor can be designed in the manner of an inductive or capacitive coil and in this way itself represent a sensor, the coil or the magnetic field generated by it being monitored in such a way that faults lead, for example, to an alarm. If the magnetic field of the conductor is disturbed, there may be a break-in or attempted break-in.

If the frame is made of solid profiles, which are made of wood, for example, grooves can be milled or cleared, into which the conductor is inserted at the factory, depending on the position of the groove, this is then closed with an insert and / or covered with a cover . By preparing the frame with the installed conductor, the subsequent arrangement of any electrical / electronic sensors / actuators is possible with very simple means. In a relatively simple case, the at least one conductor, which preferably extends in a ring or spiral along the frame, forms an antenna or a capacitive or inductive coil.

The conductor is arranged in a ring or star shape in the frame and connected to the interface. In order to connect a large number of sensors and / or actuators to the interface, the conductor comprises a data bus and / or ensures a power supply from the interface to the sensors and / or actuators. Corresponding control components of a bus system can either be accommodated in the frame or in the data processing device. Furthermore, the conductor can be connected to a voltage network, in particular also via the interface, or connected to an energy source in the form of a battery or a rechargeable battery inside or outside the frame.

The conductor is applied to the hollow chamber or solid profiles made of plastic by means of a plasma process. In order to apply the conductor to a place that is difficult or impossible to see in the finished state of the frame, the rod profiles are metallized, that is to say the semi-finished products, which are cut to a certain length to produce the frame. In order to connect the conductors of the individual frame sections to one another, the conductor is connected in corner regions of the frame with a conductive adhesive or a conductive corner connector and / or covered with a protective lacquer. The protective lacquer can on the one hand be electrically insulating and on the other hand protect the at least one web-shaped conductor and / or the corner connector or the adhesive against corrosion.

According to a further development, the conductor extends from a common interface on the one hand through a frame and on the other hand through a casement. The entire frame, that is to say both its movable sash frame and the fixed frame, is thus prepared for the mounting of sensors and / or actuators.

In order to further simplify the installation of a sensor or actuator, a reverse polarity-proof plug connection is preferably connected to the conductor for electrical and / or data technology coupling. The plug connection is assigned, for example, a prefabricated opening or a marking on the outside of the hollow chamber profile so that the fitter can arrange the sensor or actuator at the predetermined position.

The plug connection can be protected against the ingress of moisture and, for example, a seal included, which lies against the sensor or actuator to be installed or in the area of the plug connection there is a self-healing insulation of the conductor, which protects the electrical contacts and the conductor against the ingress of moisture.

In one embodiment, the interface for coupling the conductor to the data processing device is wireless and / or the sensors and / or actuators communicate wirelessly with the data processing device, which can be part of a house control. It can be a so-called Bluetooth interface or a radio interface or the like. The integration can also be done in a WiFi. Corresponding transmitting and / or receiving devices can either be accommodated in the frame or, for example, in a roller shutter box assigned to the frame

For the mechanical fastening of the sensor or actuator, a non-positive and / or form-fitting holder is arranged on the frame side.

Accordingly, a self-sufficient sensor or actuator can be clipped, for example, into the hollow chamber profile of the frame, and a guide device, for example in the form of a tongue and groove connection or the like, can be provided to secure the position. It is also possible to fasten the sensor or actuator with a type of compression fitting, wherein part of the compression fitting or cutting ring fitting can be attached to the frame. The holder comprises a clip and / or screw connection and can be closed with a cover. The cover can be designed as a type of stopper or screen and cover a prepared opening and or the sensor or actuator used.

To adapt to different sensors or actuators, the holder can be equipped with a reinforcing element and / or an adapter for adapting to the size and / or stability requirements of the sensor or actuator to be installed. The adapter and the reinforcing element can be designed like a sleeve and / or rest against the hollow chamber profile on the inside and / or on the outside.
According to a further development, the data processing device communicates via a network with handheld devices in order to call up data from the installed sensors and / or to control actuators. The network can be a home network or a global network. If communication takes place, for example, via the Internet, a user of the handheld device can call up data from the installed sensors worldwide and / or control actuators.

For the energy supply of the installed sensors and / or actuators and / or interfaces, a voltage source connected to the conductors is expediently accommodated in the frame or the conductors are connected to a voltage source outside the frame. A battery, a rechargeable battery, a photovoltaic element or the like can be installed on or in the frame as the voltage source.

The sensors used preferably record measured variables and / or states and / or changes in measured variables or states on or in front of or behind the frame. Sun sensors and / or temperature sensors and / or wind sensors and / or image acquisition sensors and / or vibration sensors and / or position sensors and / or distance sensors and / or moisture sensors and / or fingerprint sensors are to be installed and to be coupled with the data processing device. With the image capture sensors, the surroundings can be captured and the images can be displayed on a display device of a smartphone or on a screen coupled to the data processing device. In addition, facial recognition or the like can also be carried out if the data processing device comprises appropriate software or hardware means, for example in the form of a field programmable gate array (FPGA). Of course, the sensors mentioned above are not a final compilation, but an exemplary list.

Shutter drive motors and / or rotary drives for pivoting the casement relative to the frame and / or locking motors for driving a locking mechanism and / or fan motors and / or actuators for ventilation slides or ventilation flaps are to be connected to the data processing device as actuators. If an access authorization is determined by the data processing device on the basis of a recognized face or fingerprint, the data processing device can control a locking motor to unlock the locking mechanism and / or a rotary drive for pivoting the sash frame relative to the frame. If the data processing device detects ventilation based on the data or signals from moisture sensors, temperature sensors, air quality sensors or the like, then a fan motor and / or actuators for ventilation slides or ventilation flaps are activated. Of course, the actuators mentioned above are not a conclusive compilation, but an exemplary list.

It goes without saying that the features mentioned above and still to be explained below can be used not only in the respectively specified combination but also in other combinations. The scope of the invention is defined only by the claims.

The invention is explained in more detail below on the basis of several exemplary embodiments with reference to the associated drawing.

In view of its construction essential to the invention, the frame is identical for use as a sash frame 1 for a window 2 and / or a door 3 and essentially consists of rectangular hollow chamber profiles 4, although other geometries are of course also included without leaving the scope of the invention. It is also possible to make the frame rigid.

The sash frame 1 has a hinge side 5 with hinges 6, via which the sash frame 1 is articulated to the frame 7 fixed on the building side, both simple window fittings or turn-tilt fittings being able to be arranged both in the window 1 and in the door 3. On the opposite side of the hinge 5 is the closing side 8, which is provided in particular with a door 3 with a lock and with both the window 2 and the door 3 with a handle which interacts with the lock or a lock.

To increase the security of the building as well as the comfort of the users of the building and to save energy, it is essential to equip the windows 2 and doors 3 of a building with different sensors 9 and / or actuators 10, which are ideally coupled to a data processing device 11 .

In order to prepare the casement 1 in the factory such that any sensors 9 and / or actuators 10 can be retrofitted, i.e. their installation is possible if the casement is already assigned to the building as intended, at least one conductor 12 is arranged in the hollow chamber profiles 4 of the casement 1 , wherein a conductor 12 comprises a plurality of current paths / wires 14, at least two of which are used for the voltage supply and further lines 15 are assigned to a data bus. Of course, it is also possible to assign a separate voltage supply, for example a battery or a rechargeable battery, to the sensors 9 and / or actuators 10. Control components of the data bus can either be accommodated in the hollow chamber profiles 4 or assigned to the data processing device 11.

The conductor 12 is connected in the area of the hinge side 5 with an interface 13 for wireless or wired coupling to the data processing device 11 and is laid in a ring through both the sash frame 1 and the frame 7 and the sensors 9 or actuators 10 are connected in parallel to the conductor 12 . In order to avoid or reduce possible disturbances, which can arise from moisture in the area of electrical / electronic connection points, the conductor 12 is covered with a self-healing insulation or sealing means are provided at the respective piercing point. Of course, the conductors 12 can also be branched, as is indicated by the conductor 12 running through a filling 19. A current can also be fed in via the interface 13, as is the case, for example, with the known USB interface. In its course through the casement 1, the conductor 12 has reverse-polarity-protected plug connections 16, which comprise a collar 17 with an inside nose 18 for receiving a connection base of the sensor 9 or actuator 10 to be mounted and, for example, self-healing electrical insulation. For the mechanical fastening of the sensors 9 or actuators 10, the hollow chamber profile 4 can have factory-made openings in the area of the plug connections 16, which can be closed with a cover when not in use, or markings which are visible from the outside on the hollow chamber profile 4 are attached at the factory to which the Indicate the placement of the plug connections 16, so that the openings required for the mounting of the sensors 9 or actuators 10 have to be made in the correct position if necessary.

As an actuator 10, for example in the area of the hinge side 5, a rotary drive 20 for pivoting the casement 1 relative to the frame 7 is provided on a hinge and on the firing side 8 in the area of a lock or other lock is a locking motor 21, of course a corresponding gear is assigned , arranged to drive a locking mechanism. Furthermore, in the case of a window 2, it can be useful to provide a blind drive motor 22. All of the aforementioned actuators 10 are connected to the data processing device 11 via the conductors 12.

As sensors, for example, a sun sensor 23 and a wind sensor 24 are installed on the window 2 and a fingerprint sensor 25, a distance sensor 26 and a vibration sensor 27 on the door and are connected to the data processing device 11 via the conductors 12.

At least one input device 28, for example a keyboard and / or a mouse, and a display device 29 are connected to the data processing device 11. The data processing device 11 connected to the interface 13 receives and processes signals from the connected sensors 9 and controls the coupled actuators 10. Furthermore, the data processing device 11 can communicate with a smartphone 30 or a tablet computer or the like via a WLAN and / or the Internet or the like, for example in order to to enable a remote user to query sensor data and / or to control the actuators 10.

If a user places his finger on the fingerprint sensor 25, the latter communicates via the conductors 12 with the data processing device 11, on which are stored model fingerprints, which determine whether or not the user is authorized or not based on a comparison of the fingerprint with the model fingerprints . If authorization is present, the locking motor 21 is controlled by the data processing device 11 to unlock a lock. Furthermore, the door 3 can be opened automatically, for example, by appropriately actuating the rotary drive 20. The open position of the door 3 is detected by the distance sensor 26 and signaled to the data processing device 11. If the door 3 is open for a longer period of time and / or a vibration sensor 27 supplies a corresponding signal to the data processing device 11, an alarm signal can be triggered when an alarm function is activated and a corresponding message can be displayed on the display device 20 and / or the smartphone 30.

If the sun sensor 23 supplies data to the data processing device 11 that exceed a stored limit value, the data processing device 11 controls the blind drive motor 22 via the interface 13 and the conductor 12 in order to close the blind connected to it. If the wind sensor 24 supplies data to the data processing device 11 that exceed a data stored with respect to a wind speed, the data processing device 11 asks in which position the blind assigned to the corresponding window 2 is located. If the blind is closed, then the blind drive motor 22 is actuated to open the blind.

Because the sensors 9 and actuators 10 can be retrofitted, a user can, for example, first install the safety-relevant sensors 9 and, at a later point in time, the comfort-increasing actuators 10, which enable the door 2 to be opened automatically. A window 2 can be operated in the same way.

The conductor 12 with one or more current paths 14 is applied to the sash frame 1 and / or the frame 7 in a plasma process, the metal being preferably already deposited on the rod material from which the frame 1 or frame 7 is composed. The conductor 12 may have corner connectors 31 in the corner region of the casement 1 and the frame 7, which couple the individual sections of the conductor 12 to one another. The conductor 12 can be arranged in the manner of an inductive or capacitive coil 32 and itself as a sensor 9, for example for the detection of a metallic intrusion tool in the coil area, or as a connector for sensors 9 and / or actuators 10 with a computer device and / or a current / Be designed as a voltage source.

The conductor 12 can be applied or arranged in a fold area so that it does not have an optically disturbing effect. Furthermore, it is possible to coat the conductor 12 and the corner connectors 31 with a lacquer for protection, in particular against corrosion.
