Description

Technical area

The invention relates to a multi-function handle for the controlled opening and closing of windows or doors with a detection device for detecting certain current handle positions in order to support a targeted ventilation of rooms can.

The term "multifunction grip" is understood to mean all types of grip used in windows and doors. They have a handle body, which can be actuated by hand and preferably ergonomically fits in the hand. Also so-called olive handles are handle body for such a multi-function handle.

State of the art

There are already known handles for opening and closing windows or doors in different embodiments. For example, in the DE 10 2005 053 821 A1 a so-called wireless adapter for a window or door handle described, with each of which the current grip position is detected and then wirelessly transmitted to a central station. For this purpose, the wireless adapter is plugged into the window handle and door handles usually present handle actuating pin, which thereby frictionally engages in a cam whose lateral cam surface is scanned by an actuating pin of a microswitch so as to correspond to the current grip position positions " open "or" closed "to detect. Here, a position change can also be displayed directly on the wireless adapter, by providing light-emitting diodes, the z. B. lights red when the windows or doors "open", and green when they are "closed".

From the DE 10 2004 018 064 A1 Furthermore, a monitoring device for window handles is known whose respective position is to be monitored remotely. For this purpose, the respective handle shaft or the respective handle bolt carries a shift gate, which controls the individual gripping positions associated sensors whose output signals are then fed by radio to a reporting center.

However, such multifunctional handles are complex in their respective construction and thus associated with relatively high cost and are therefore z. B. less suitable for private users.

In this context, finally, in the DE 103 23 686 A1 a so-called ventilation control sensor has been proposed for the precise control of the opening and ventilation intervals of windows and doors, in order to be able to demonstrate that in the case of possible mold formation the tenant has probably not ventilated enough. With this ventilation control sensor, which can be attached to the respective window or door, each opening or closing with opening period and date should be electronically registered and stored so that this information can be retrieved with a suitable reader and stored in a computer. In this case, this ventilation control sensor can optionally be equipped with a humidity meter, a timer in conjunction with a signal tone or only with a detection chip for the control of the opening or ventilation intervals. This control device can certainly be of interest to a landlord in order to justify a possible mold growth because of insufficient ventilation, but so that the current handle position of a window is not detected and thus not the current ventilation as aired, "tilted" or "opened ".

Object of the invention

In contrast, the present invention seeks to provide a low-priced multi-function handle for the controlled opening and closing of windows or doors, in which instead of a remote monitoring again to see the human reaction in the center.

Solution of the task

This object is achieved according to the invention in a simple manner, that in a multi-function handle with a detecting device for detecting certain current gripping positions, this additionally has a transmitter that includes a timepiece with an adjustable period whose expiration by at least one acoustic noise or equivalent electronic or mechanical Signal is displayed.

At the same time it is also possible to additionally provide an optically effective light source, such as an LED light source to the multi-function handle, whereby a user in addition to a sound is also visually reminded that z. B. an open window still needs to be closed.

Advantages of the invention

According to the present invention, it is expedient that the timepiece is coupled via the transmitter so with the detection means that at least at the handle positions "tilted" and "open" with the end of the set period of time, the acoustic noise is heard, it from Be an advantage may be that when the handle position "tilted" another acoustic noise is heard than in the handle position "open".

It is also advantageous if the acoustic noise can be heard as a clear tone or a melody and the duration of the opening, z. B. a window, the acoustic noise itself and its beginning on the timing instrument is made adjustable. This makes it possible, the time duration for leaving a tilted window z. B. to 15 minutes, d. H. after this time then sounds z. For example, a beep sounds to remind the user to close this window. But it is also possible to set the time measuring instrument so that after this time window and the whistle to z. B. 10 minutes again a whistling sound is heard, which prompts the user again to close the window, so that the ventilation process does not last indefinitely, because the multi-function handle according to the invention is mainly to help save energy.

Further, it is possible to pre-set the sequence of the acoustic sounds both at regular intervals and at different intervals.

The multi-function handle according to the invention itself can be brought from an original vertical position into a "tilted" by 90 ° or 180 ° "open" twisted position, in which case it is expedient that the time measuring instrument is designed such that this with the measurement of The set time period only starts when the multi-function handle has been rotated by 90 ° or 180 °.

A further alternative embodiment of the multi-function handle according to the invention can provide automatic detection for detecting the position of the handle. In particular, for this purpose, technical or electronic components are known which correspond to a position sensor, so that a switching operation is triggered by a slight pivoting of the multi-function handle, which is then to assign the interpretation that the window is open. From this point on, the corresponding electronic signal can then be generated and provided in the predetermined time window.

A further preferred embodiment provides for a switching element which switches off the device for detecting the position or position of the handle and thus the output of the signal. It is further provided that a temperature element is arranged, which detects the temperature gradient in the region of the opening of the window and can be determined by this temperature gradient, if the window exclusively for ventilation purposes (especially in winter, since here the temperature gradient between the outside temperature before the window and on the inside of the window is relatively large) or if the window is only opened to cool the room (here the temperature gradient between the outside temperature in front of the window and inside the window is small).

To ensure the power supply permanently, is also advantageously provided to provide the handle or the fitting with appropriate solar cells.

A further alternative embodiment provides that the electronic components not in the grip, but to arrange within the fitting or instead of the fitting or in addition to the fitting. If the components are arranged in addition to the fitting, it is necessary to provide longer screws for attachment to a window frame.

If the window handle is arranged on an oblique roof window, it is conceivable, in addition to the aforementioned features, to arrange a moisture measuring sensor in the region of the handle. This detects when in a corresponding rainy weather the roof window is open. Because of the opening of the roof window, the handle is exposed to the environment and gets wet when using the rain. An acoustic signal or other signal (for example GSM signal or sending an SMS or similar) can prevent major damage.

A further preferred embodiment provides that in or on the handle, a display device is arranged, which always displays, for example regardless of the position of the handle correctly in viewer height, how much time is left until the corresponding signal is triggered.

The signal can be displayed, for example, in the form of a pictorial egg timer.

In another embodiment it is provided that the display is removable. When the display is removed, the time interval begins at the time of removal, and regardless of the location, the user can determine when the time has elapsed beyond which effective ventilation will no longer occur. Thus, the user can also move far from the open window and always receives a corresponding signal to close it again. In particular, this results in the advantage that no data transfer from the handle to the display is necessary.

In addition, in one embodiment, the design of the multi-function handle can be designed such that already on removal of the multi-function handle from its rest position (corresponding to closed window) sounds a warning signal. This multifunction grip also has a child safety lock.

Alternatively, it can also be provided to couple a reed contact with the multi-function handle. Thus, on the one hand, the position of the handle body, but also at all the position of the window (regardless of the position of the handle body) can be determined.

The multi-function handle according to the invention is advantageously used in standardized windows and doors and can be designed so that you can replace previously existing on windows and doors existing handles. Also, the multi-function handle can be configured quasi as a kind of memory or memory handle on a provided on this display with keyboard adjustable.

Short description of the drawing

Further details and advantages of the invention will be described below with reference to a single 1 described in more detail, showing a simplified schematic diagram of a multi-function handle according to the invention in a side view.

Way to carry out the invention

The in 1 in a side view simplified illustrated multifunction handle - referred to 1 - For a window or a door has a handle body 2 , the square in cross section formed actuating pin 3 has, with which it can be positively engaged with an integrated in the window or door locking mechanism engaged. Upon rotation of the handle body 2 , z. B. by 90 °, then actuates the actuating bolt 3 the locking mechanism, thus tipping, opening or closing z. B. a window sash can be performed.

On the actuating bolt 3 is a fitting to be fixed to a window frame or door leaf 4 attached, on which a horizontal section 5 of the handle body 2 adjacent, in which a detection device 6 is housed for detecting certain gripping positions. In the with 7 designated vertical portion of the handle body 2 there is both a timepiece (time timer) 8th with an evaluation electronics 9 as well as a sound converter 10 and a battery 11 showing the current for the linked parts 6 - 11 supplies.

The detection device 6 which in a known manner in a form-fitting manner with the actuating bolt 3 is connected, z. B. have sliding contacts that recognize certain grip positions due to a cam, but is another suitable position identifier of the multi-function handle 1 also possible.

The timepiece 8th is about the transmitter 9 with the detection device 6 coupled so that when a handle position "tilted" and "open" contact with the timepiece 8th is produced, whereby the user is then reminded after a certain set time by an acoustic noise that the respective window or door still has to be closed, ie the desired ventilation process of a room is now completed. In other words: the time measuring instrument 8th is designed so that this only starts with the measurement of the set period when the multi-function handle 1 from its original vertical position has been rotated by 90 ° or 180 °.

The timepiece 8th and / or the transmitter 9 own actuators 12 - 14 of which the actuator 12 to set an individual time to ventilate a room. At the same time, the beginning can also be determined when using the sound transducer 10 an acoustic signal is to sound, which should be a signal in the present embodiment, which corresponds to a clearly audible beep, the setting can also be chosen so that it is repeated at certain intervals, ie intervals. With the actuator 13 You can adjust the volume of the sound, while the actuator 14 serves for switching on and off.

Industrial Applicability

Starting from an original vertical position of the multi-function handle 1 , z. B. on a window, this is z. B. rotated 90 °, whereby the window "tilted" and thus the corresponding space can be ventilated. In this tilted position of the window signals the detection device 6 via the evaluation electronics 9 the time measuring instrument 8th in that this tilting position exists, whereby a ventilation period of, for example, 20 minutes begins to run, either before and immediately by means of the actuator 12 has been or will be discontinued. After the end of the set time of 20 minutes has been reached, then sounds through the transducer 10 the acoustic noise, which reminds a user to close the tilted window again.

Thus, the tilted window can not be forgotten and at the same time be prevented that the ventilation process does not last infinitely long. The multifunction handle according to the invention 1 thus contributes to save energy in a simple way, which is particularly important in winter.
