Definitions

  • the invention relates to a window handle coupling with an expanding material drive for user-independent ventilation of rooms and a window with such a window handle coupling.
  • Ventilation profiles are known, for example, which are attached to a window frame in such a way that an air passage is formed between the window frame and the window sash in the area of the ventilation profile.
  • This air passage allows air to be exchanged between the living space and the outside air.
  • the disadvantage of this is that this causes a permanent exchange of air, which can only be ended by removing the ventilation profiles.
  • This permanent exchange of air impairs living comfort and is also extremely questionable in terms of energy, since increased heating expenditure can be the result.
  • GB 2 137 748 A discloses a thermal actuator comprising a wax placed in a closed cavity. The wax expands depending on the temperature and can thus activate a window opening mechanism.
  • the EP 2 495 380 A2 discloses a fitting for a window or a door or the like with a sash that can be tilted at least about a horizontal axis, the fitting having a tilting opening limiting arrangement with at least one link which is mounted to be longitudinally displaceable at least in the circumferential direction of the fold via a coupling element and for limiting the tilting opening with a first stop interacts.
  • the proposed solution should be implemented with as little effort as possible.
  • the window handle coupling according to the invention for user-independent ventilation of rooms is designed with a coupling element, which is designed with a receptacle for a mandrel of a window handle and is to be arranged in engagement with a gear for moving the fittings of a window, a housing and an expanding material drive, the expanding material drive with an expansion element and a spring element, the spring element is fixed to the coupling element and to the housing, and the expansion element is designed and arranged in such a way that an expansion of the expansion element causes a force to be applied to the spring element near the fixation on the housing and thus a rotation of the window handle coupling to at least partially open the window.
  • the window handle coupling is intended to enable user-independent ventilation of rooms.
  • a window must be at least partially opened, at least the contact pressure of the window sash on the window frame must be reduced, so that a defined leakage of the window occurs, through which an exchange of air between the room air and the outside air can take place.
  • this is achieved by manually rotating the window handle to the so-called quarter position, i.e. turning it by about 45°.
  • the contact pressure is now reduced, but the window as such is closed. This achieves increased joint ventilation, which is sufficient to remove increased humidity.
  • the window handle coupling according to the invention is a comparable effect is to be achieved by the window handle coupling according to the invention, but without the action of a user.
  • the window should preferably be at least partially opened, in particular in the quarter position described above.
  • the window handle coupling has a coupling element, which in turn has a receptacle for a mandrel of a window handle, the mandrel usually being understood as an element for forming an operative connection between a window handle and a gear for the fittings of a window.
  • the coupling element is to be arranged in engagement with the gear for moving the fittings of the window, so it can be used or installed in such a way that this engagement occurs.
  • the window handle coupling is therefore arranged between the usual and well-known window handle and the gear for moving the fittings.
  • On the room side it accommodates the window handle with its mandrel, so that they engage with each other and the rotational movement of one carries the other along and vice versa.
  • the coupling element engages in the window's own gear, with which the fittings of the window are moved in order to open or close it.
  • the mandrel of the window handle engages directly in this gear and a rotation of the window handle causes the movement of the fittings, so that the window can be opened or closed.
  • the coupling element is interposed. When the window handle is acted upon, the coupling element rotates about the axis of rotation provided by the mechanism of the fittings.
  • the coupling element has an expanding material drive.
  • a housing encloses the coupling element and the expansion drive at least partially, preferably completely.
  • the expansion drive is formed with an expansion element and a spring element.
  • Expansion elements are known per se and are made with materials whose volume changes significantly, usually increases, as a result of external influences such as moisture, temperature or electrical voltage. When the effect is removed, the change in volume usually decreases.
  • the spring element is used to transfer the change in volume of the expansion element to the coupling element.
  • the spring element is fixed to the coupling element and to the housing of the window handle coupling or connected to them.
  • the shape, size and arrangement of the expansion element is now such that the expansion of the expansion element takes place essentially in the direction of the fixed point of the spring element on or in the housing. This causes a force to be applied to the spring element close to the fixed point with the housing, with "close” primarily meaning that the force is applied closer to the fixed point of the housing than to the fixed point with the coupling element.
  • Said application of force acts in such a way that the housing is moved in the direction in which the force acts. Since the window handle coupling and in particular the coupling element can be rotated around the axis of the gear and with the gear for the window fittings, the force input in connection with the distance to this axis of rotation and the connection of the housing with the coupling element by the spring element causes a rotation of the Window handle coupling causes. This rotates around the axis of rotation of the gear of the window fittings and, due to the respective mutual engagement with one another, takes both the gear and the window handle with it. This ensures that the fittings of the window are at least partially opened. A rotation of about 45° is preferably achieved, so that the quarter position of the window is reached, in which, as already stated, the contact pressure of the window sash on the window frame is reduced and joint ventilation is established.
  • the design and arrangement of the window handle coupling does not impede manual operation of the window handle by a user to open or close a window, but offers additional functionality.
  • the window handle coupling instead of the usual three window positions “closed”, “tilted” and “open”, there is one more, namely the ventilation position with reduced contact pressure.
  • window handle can also be understood synonymously here as a handle for balcony doors, terrace doors and the like.
  • the expansion-material drive is designed with a moisture sensor, an energy supply and a thermoelectric expansion-material element or with a moisture-sensitive bionic expansion-material element.
  • the expansion material drive is designed with a spring element and an expansion material element, which in this embodiment of the spring grip clutch according to the invention is designed as a thermoelectric expansion material element.
  • the expansion drive of this variant has a moisture sensor and an energy supply.
  • the humidity sensor is intended to record the ambient air humidity. Its specific design is of secondary importance, but it has proven to be advantageous to design the humidity sensor as a hygrostat, for example as an electrolytic polymer sensor.
  • the humidity sensor is preferably arranged at a point in the room that is representative of the development of the room air humidity; it does not have to be arranged directly on or in the window handle coupling. It is essential that this interacts with the thermoelectric expansion element and the energy supply.
  • the humidity sensor is coupled wirelessly or wired to the thermoelectric expansion element and the energy supply in such a way that it releases energy into the thermoelectric expansion element when a predetermined humidity level is reached or exceeded.
  • the energy fed into the thermoelectric expansion element causes it to heat up and thereby expand.
  • a force is applied to the spring element and the rotation of the window handle coupling is achieved. If the humidity drops again and falls below the specified limit value, the energy supply to the thermoelectric expansion element is interrupted. This can now cool down and its expansion decreases.
  • the window handle clutch is reset to its initial state.
  • the expansion element is designed as a moisture-sensitive bionic expansion element.
  • a power supply or a humidity sensor is not required, as shown below.
  • an expansion element is formed with a material that expands with increasing humidity.
  • the expansion element can be arranged in the housing of the window handle coupling without an additional opening; the leaks in the window handle and window handle coupling caused by production are sufficient for the increased humidity to penetrate to the moisture-sensitive bionic expansion element.
  • an additional opening can be provided in the housing of the window handle coupling in order to facilitate the air supply to the bionic expansion element.
  • the bionic expansion element expands when a specified humidity level is reached or exceeded, force is applied to the spring element up to the point of rotating the window handle coupling.
  • the window handle coupling is also reset if the expansion of the expansion element decreases due to falling humidity.
  • the rotation of the window handle coupling is limited.
  • the possible rotation of the window handle coupling is limited. This can be desired, for example, in order not to impair the burglary protection of a window with the window handle coupling according to the invention. This usually continues in the quarter position of a window handle and the associated joint ventilation.
  • its material or material composition, its size and/or its position in relation to the spring element can be selected and/or limited in such a way that no further expansion and/or additional force is applied to the spring element, even if the air humidity continues to rise.
  • the spring deflection of the spring element and/or its spring force can be selected in such a way that the rotation of the window handle coupling that can be achieved with it is limited.
  • a further embodiment of the window handle coupling according to the invention is when the window handle coupling has a freewheel element in order to bring about a mechanical decoupling of the window handle coupling.
  • a freewheel element can be a freewheel lever, for example.
  • the freewheel element is arranged in such a way that when the window handle is operated manually, it acts on the spring element so that it is unlocked. As a result, the window handle can be rotated to open the window without the housing and the expanding material drive of the window handle coupling also rotating.
  • the window handle coupling advantageously has a communication device in order to form remote access.
  • the communication device is designed with a transmitting and receiving device, by means of which information is received and transmitted wirelessly or by wire, for example by means of an application on a smartphone. It is expedient here for the communication device to have an IP address or be assigned an IP address so that it can be uniquely addressed and thus reached. The principle is known from the "Smart Home" sector.
  • remote access can be used to retrieve its status, i.e. whether it is open or closed, and/or sensor data or adapt target data and thus adjust the triggering torque for the rotation of the window handle coupling become.
  • the communication device can be arranged on or in the window handle coupling, or it can be arranged at a distance or offset from it, provided there is a coupling between the window handle coupling and the communication device.
  • the expansion material drive provided therein can be sensitive to the outside air temperature, outside air humidity, the room air temperature and/or the room air load. This is to be understood to mean that the expansion material drive causes the window handle coupling to rotate even when one or more of the room air parameters mentioned is reached or exceeded.
  • the indoor air pollution can be recorded, for example, by the content of CO 2 or VOC (volatile organic compounds).
  • the expansion material drive can be designed with additional sensors for detecting the outside air temperature, outside air humidity, the room air temperature and/or the room air pollution or with a multispectral sensor for the simultaneous detection of several room air parameters.
  • the sensor or sensors can be arranged on or in the window or its components, or in the window handle coupling or at a location representative of the air parameter.
  • the representative location can be the same location as the location for the humidity sensor.
  • the additional sensor or the additional sensors can be arranged in a common housing with the humidity sensor.
  • the expansion-material drive is designed with a thermoelectric expansion-material element and an energy supply
  • the additional sensor(s) releases an energy supply into the thermoelectric expansion-material element so that it heats up and expands.
  • this can be designed so that it expands alternatively or in addition to humidity when one or more air parameters other than humidity are reached or exceeded, which leads to the desired rotation of the window handle coupling.
  • the additional room parameters can expediently be called up and/or evaluated remotely, if they are recorded by means of one or more sensors, for example in order to document the ventilation behavior. It would also be possible to adjust the limit values remotely in this way.
  • the opening behavior of the window handle coupling can be adjusted and thus an adjustment can be made to the point of optimizing the ventilation process.
  • This can be done, for example, by means of a room air management device.
  • This can have a control device for evaluating recorded air parameters such as room air temperature, room air pollution, outside air temperature, air humidity in the room and possibly also the outside air.
  • the result of the evaluation can show, for example, whether an exchange of air makes sense when comparing the outside air temperature and inside air temperature, taking into account the humidity and/or air pollution.
  • the rotation of the window handle coupling is not triggered, although one of the limit values may have been reached or exceeded, since ventilation would not bring any improvement in the room air in this case.
  • Special scope In addition to controlled ventilation with regard to humidity, there is temperature management, in which the ventilation position of the window is used to achieve or maintain a desired room air temperature. This is particularly preferably done in conjunction with remote access, so that the user can also set the desired temperature remotely.
  • the window handle coupling advantageously has locking monitoring. This should make it possible to determine whether the window is completely closed or in the ventilation position, and also whether it is tilted or open.
  • the states can be determined by evaluating the sensor data recorded by the window handle coupling. A significant drop in humidity and/or a change in room air temperature suggest that the window is at least partially open. This applies in the same way to a significant change in the indoor air pollution.
  • the degree of opening of the window can also be deduced from the course of the parameters over time. The faster the parameter or parameters change, the wider the window is open.
  • the window handle coupling can be designed with a device for detecting the position of the window handle and/or the position of the coupling device, for example in the form of one or more Hall sensors and a number of magnets, which are essentially ring-shaped around the window handle and/or the coupling element are arranged so that the position of the window handle or the coupling element can be detected and determined, from which in turn the opening state of the window can be inferred.
  • a device for detecting the position of the window handle and/or the position of the coupling device for example in the form of one or more Hall sensors and a number of magnets, which are essentially ring-shaped around the window handle and/or the coupling element are arranged so that the position of the window handle or the coupling element can be detected and determined, from which in turn the opening state of the window can be inferred.
  • such a lock monitoring is not only used to provide information to the user, he can also trigger the closing of the window via remote access.
  • burglary monitoring can also be carried out using locking monitoring. If an open window is detected although, for example, the sensor data does not require it to be opened, a warning can be sent to the occupant or user of the room. If he is not present or if he has reason to believe that a break-in has occurred based on the warning, he can call the police.
  • the window handle coupling according to the invention can be designed as a retrofit element for a window. It can thus be achieved that even old windows or windows according to the prior art can be retrofitted with the window handle coupling and can benefit from their functionality.
  • the design of the window handle coupling makes it possible to remove the window handle of an existing window, to bring the window handle coupling into engagement with the gear mechanism of the fittings provided there and then to insert the window handle into the Use window handle coupling. The installation is therefore quick and easy to handle.
  • the window handle coupling can be adapted to the existing window or windows in terms of geometry, material and design in such a way that it blends in well with the window and adjustment work on the existing window and in particular the mandrel of the window handle is not required.
  • a window with a window handle coupling according to the invention is also claimed.
  • the window handle coupling can be used during window manufacture or integrated into the overall window system. This means that on-site assembly is no longer necessary and it is ensured that the window handle coupling has been installed correctly. In addition, the installation of the window is not delayed in this way.
  • the window handle coupling With the window handle coupling according to the invention and a window with such a user-independent ventilation of rooms. If a limit value of a room air parameter, such as air humidity, is reached, the window handle coupling causes the window to be in a ventilation position, in which an increased air exchange rate is achieved compared to when the window is closed. The resident or room user does not have to intervene. Adequate ventilation of a room is thus achieved without additional technical components or a constant air exchange of the room air with the outside air, which regularly results in a weakening of the building envelope in terms of tightness and sound insulation. Such a weakening is not necessary with the window handle coupling according to the invention.
  • the resetting of the window handle coupling when there is sufficient air exchange ensures that energy is not unnecessarily required to compensate for the room climate, since the window closes promptly if the specified limit values are not reached. Needs-based ventilation is therefore achieved.
  • figure 1 shows a top view ( Figure 1a ) and a cut ( Figure 1b ) by an exemplary embodiment of the window handle coupling 10 according to the invention.
  • the window handle coupling 10 was subsequently installed in an existing window.
  • the window handle 12 with its mandrel 14 was removed from the window sash 40 and the mandrel 14 was shortened to the necessary size.
  • the window handle coupler 10 was engaged with the window hardware gear 16 and then the window handle 12 with the mandrel 14 shortened was inserted into the window handle coupler 10 .
  • the interaction of the relevant assemblies is additionally made figure 2 clear, in which the presentation is simplified and perspective for the sake of clarity.
  • the window handle coupling 10 is formed with a housing 22, a coupling element 20 and an expansion material drive with a thermoelectric expansion element 24 and a spring element 26.
  • the spring element 26 is attached to the coupling element 20 (in Figure 1a at its left end) and housing 22 (in Figure 1a fixed at its right end).
  • the coupling element 20 establishes the engagement or the operative connection with the gear 16 for the fittings of the window and also provides a receptacle for the mandrel 14 of the window handle 12 .
  • the expanding material drive has a moisture sensor and an energy supply 32 in the form of a low-voltage power supply.
  • the humidity sensor is arranged at a point in the room that is representative of the development of the room air humidity and coupled to the power supply 32 .
  • the humidity sensor is designed with an electrolytic polymer sensor, which has a preset switching point when a critical humidity level is reached. If this critical air humidity is reached, the humidity sensor releases the energy supply 32 so that current flows into the thermoelectric expansion element 24 and causes it to heat up.
  • the thermoelectric expansion element 24 now expands in the direction of the fixed point of the spring element 26 on the housing 22 (in Figure 1a to the right and slightly down).
  • a rotation of about 45° is achieved, so that the quarter position of the window handle 12 is reached, in which the contact pressure of the window sash 40 on the window frame is released and joint ventilation occurs.
  • This joint ventilation causes an exchange of air between the room air and the outside air.
  • the opening width of the window handle coupling 10 is limited to this 45° by its specific structural design in order not to impair the burglary protection of the window even in the ventilation position that has now been reached. Further explanations follow below.
  • the ventilation position is in figure 3 shown together with the other opening positions of a window with the window handle coupling 10 according to the invention, wherein Figure 3a a closed window Figure 3b a window in the ventilation position caused by the window handle coupling 10, Figure 3c an open window and Figure 3d shows a tilted window.
  • thermoelectric expansion element 24 If the air humidity falls below the critical level as a result of the ventilation and is detected by the humidity sensor, the energy supply to the thermoelectric expansion element 24 is interrupted. There is no further heating, rather the expansion element 24 cools down and its expansion decreases. Since there is no longer any force input to the spring element 26, this restores its initial state and in the process puts the window handle coupling 10 back into the initial position. The window is now closed and no longer ventilates.
  • the window handle coupling 10 In order to mechanically decouple the window handle coupling 10 when the window is opened manually, ie when a user opens the window, the window handle coupling 10 has a freewheel lever 28 . If the window is opened manually, the freewheel lever 28 unlocks the spring element 26 so that the window handle 12 can be rotated while the housing 22 is not rotated. As a result, it can be avoided, among other things, that the spring element 26 breaks when the window handle is operated manually.
  • the window handle coupling 10 is designed for remote access, that is, it has a communication device (not shown) with an IP address according to the "Smart Home" principle, so that the user can use an app on his smartphone to determine the humidity detected by the humidity sensor can retrieve. In this way, it is also possible to monitor the closure of the window in a simple manner. If the air humidity drops significantly, it can be assumed that the window is partially or completely open, with the speed of the drop in air humidity indicating the opening width of the window. Since the window handle coupling 10 only allows opening up to the ventilation position, manual opening and/or a burglary can be inferred from a further degree of opening of the window. This can be communicated to the user using the communication device.
  • the window handle coupling 10 can be designed with additional sensors for the temperatures of the room air and the outside air, for the outside air humidity and/or the room air pollution, so that these parameters can be included to assess whether the ventilation position should be set.
  • a multispectral sensor for detecting a number of air parameters can also be provided. The sensor or sensors can act on the energy supply 32 to the expansion element 24 or a control device can be interposed, which evaluates the sensor data and causes the window handle coupling 10 to rotate, if necessary.
