Description

Technical area

The present invention relates to a monitoring device according to the preamble of claim 1.

State of the art

Devices for monitoring the change in inclination of handles with wireless transmission of the inclination change, in particular for door handles and window handles, are state of the art. This reveals the DE 20 2010 013 996 a "door or window fitting ( 2 ) with a manually operable pusher, handle or push handle ( 8th ), by the actuation of which a "signal" from a "wireless transmission device ( 16 ) "..." to an external receiving station ( 18 ), ... "For this purpose, the described object uses a sensor which is arranged in the fitting plate (door plate) Thus, a special fitting plate is required to detect the handle operation, on which the sensor is mounted.

In DE 296 03 917 a "monitoring device" is described in which "a sensor device detects the operation of the handle in the case of a window or a door" and "delivers a corresponding message signal to the monitoring center." The sensor device is located in a rotary bearing housing for the handle. "Also, this arrangement requires a stationary special fitting plate (" stator "), since the invention provides a correspondence between" stator "and" rotor "(handle).

The same applies to the in EP 1 271 439 ( DE 20 110 780 ), where the stationary "handle base 216 "and the" movable handle 215 "... communicate with each other via a light beam ...".

WO 2004/109236 ( DE 103 25 800 ) describes a "sensor for detecting the position of a mechanical power transmission device". The illustrated embodiment can easily recognize a window handle. In order to detect its angular position, and "to transmit this information by means of a radio signal to a remote evaluation" to, here is the fixed fitting plate (industry term: rosette) equip accordingly, which practically means a special construction.

That meets the EP 1 838 941 ( DE 20 200 5000 784 ) with a mechanically as well as energetically self-sufficient assembly, which is sandwiched between conventional window handle and sash profile. However, such a second housing comes to the window, which is aesthetically offensive in particular because of its unloaded circumference and its height.

Disadvantages of the prior art

The cited and commented prior art has in common that for monitoring and wireless transmission of the operation or the transmission of the angular position of door handles and window handles in particular both the conventional handle (handle) and the associated fitting plate (window rosette or door plate) are to be modified or that an additional and self-contained assembly is required, but that does not allow elegant product design because of its bulky shape. These constructions, in view of the increasingly significant aesthetic demand for technical consumer goods - especially in the living area - have the disadvantage of no longer meeting the required, pleasing appearance. Furthermore - especially with door handles - in view of the diverse connection dimensions of the fitting plate / s (industry term: Türschild / he) retrofitting with the solutions described in the prior art almost impossible, so mainly for the limited market for original equipment remains accessible.

Technical task

The present invention is therefore based on the object to overcome the disadvantages described and to provide an aesthetically pleasing and easy to retrofit monitoring device.

Technical solution and advantages of the invention

This object is achieved with the features according to the preamble of claim 1, characterized in that the monitoring device is arranged on or in door handles or window handles or other handles or construction or machine elements without it to detect their rotational movement and their defined angular positions of the usual stationary and torsion-resistant recordings ("bearing blocks"), such as Fittings, door signs or window rosettes, required.

The key to this solution is on the one hand in the use of self-sufficient sensors that work without the use of stationary reference components by making use of gravity, for example as a so-called tilt switch. On the other hand, the sensors must not exceed a certain size in order to provide in conjunction with the radio transmitter module, a slim mounting assembly, preferably as a separate functional unit in made of semi-finished pipe door or door Window handles aesthetically attractive because not visible, can be installed. Accordingly, it only requires more of a replacement handle for retrofittable with the monitoring device according to the invention door or window handle sets: The original, non-rotating components - especially the variant strong door plates - logistically advantageous to remain at the door, since the autarkic motion sensors no stationary special components as a reference for make rotatable handling necessary!

To detect the change in inclination of door handles can be used on commercial tilt switch, also called tilt angle switch. Their design characterizes the English term "Rolling Ball Tilt Switch" best: Accordingly, a "heavy" metal ball is mounted rollable in a metal tube and changes its position as soon as the tube changes its horizontal angular position. In the respective two end positions of the ball in the tube, a defined, electrical switching state is reached, which is used for detecting the change in inclination of window handles according to the invention. Moreover, this type of sensors has the advantage that the electronic signal processing the sensor signal after radiation of the last angular position of the handle falls into a battery power-saving sleep mode and is activated only at the next change in inclination of the handle.

Thus, there is an event-driven acquisition and radio mode. In addition, a time-dependent - possibly cyclic - radio signal can be emitted in addition and automatically, without the handle or the Baubzw. Machine element undergoes a rotary or pivoting movement. Furthermore, an acceleration sensor can additionally be present in the monitoring device, which detects vibrations (vibrations) caused by burglary or damage and feeds them to the electronic circuit for evaluation. It turns out to be particularly user-friendly, if the program of the electronic circuit can assign the vibration of the handle of their angular position and triggers alarm with appropriate combination. This is the case, for example, when a window handle is in its vertical basic position with the window closed. In the other angular positions, the program suppresses the alarm triggering. Thus, on the one hand false alarms are excluded and on the other hand, the alarm device is always automatically activated when the window is closed.

While the angularly pivotable door handle succeeds in detecting its two angular positions - namely the essentially horizontal basic position and the actuated position "pivoted" - with (at least) one inclination switch, analogue detection of the 4 typical angular positions (2 vertical and 2 horizontal positions) is required Directions) of a (endlessly rotatable) window handle of a special angle sensor which is not marketable. Therefore, different types of designs have been developed for this purpose. Again, just as with the monitoring device for door handles - their peculiarity on the one hand is that after the direction detection of the handle (due to their inclination change) the radio transmitter module can fall into the power-saving sleep mode. Therefore, the tilt sensor must not consume power when the handle is in the idle state! On the other hand, when the inclination of the handle or the construction or machine element changes, the inclination sensor must activate the radio transmitter module with a so-called "wake-up" function, so that the latter can (immediately afterwards) detect the current angular position and emit it as a radio signal. Afterwards, the radio transmitter module falls asleep again. The sensor thus has the dual function of "alarm clock" and angle sensor! Where the "alarm clock" compared to the sensor acts as a so-called "leading switch". In addition, the sensor must have the property to consume no power when the handle is stationary.

Advantageous embodiments of the invention will become apparent from the dependent claims and the following description of preferred embodiments of the subject invention.

embodiments

The embodiments of the invention will be described with reference to 1 to 7 explained. Show it:

1 a schematically illustrated monitoring device with a one-dimensional inclination sensor for a door handle located in the starting position and the actuating position,

2 a schematically illustrated monitoring device with a two-dimensional, square tilt sensor in a horizontally and vertically oriented window handle,

3 a perspective and partially exploded view monitoring device with square recessed tilt sensor, as well as a loose and inserted into a window handle stub housing tube,

4 a monitoring device shown schematically with a circular-cylindrical recessed tilt sensor in a horizontally and vertically oriented window handle,

5 a monitoring device shown schematically with a circular-cylindrical recessed tilt sensor and a permanent magnet therein for switching circumferentially arranged reed contacts in a horizontally and vertically oriented window handle,

6 a monitoring device shown schematically with a circular cylindrical recessed tilt sensor and a rotatably mounted therein Schwerependel with a permanent magnet for switching circumferentially arranged reed contacts in a horizontally and vertically oriented window handle,

7 the in 3 shown tilt sensor in front and rear view with 3 reed contacts for the detection of 4 window handle angle positions.

A particularly robust and equally easy to install, as energy-saving embodiment provides that preferably angularly operable handles - such as door handles - are designed as hollow pipe handles, in the cavity of a self-sufficient monitoring device is used. The most important component of this independent functional unit is its inclination sensor NS. 1 shows such, arranged in a door handle TG monitoring device UV, which operates as a self-contained functional unit and on the one hand from said inclination sensor NS and on the other hand a radio transmitter module FS, consisting of an energy storage ES, a circuit board PL with electronic components including (helical helix) antenna AT composed. It can clearly be seen how the ball KU in the two illustrated end angle positions of the door handle TG assumes its respective end position in the guide tube FR rolling and thus closes or opens the electrical contact EK. These two switching states assigns the radio transmitter module FS each one of the two handle positions and radiates them as a radio signal, which is detected by an external receiver, evaluated and possibly displayed.

When installing the guide tube FR one aligns its axis expediently in the bisector of that angle, which is formed by the two Türgriffwinkelendlagen.

The analogous embodiment is much more difficult for window handles FG: while for door handles TG to 1 the operating angle is limited, and consequently the inclination sensor NS shown there is comparatively simple and acts, the inclination sensor NS for window handles FG must detect the two vertical and the two horizontal angular positions in their rotational movement in both directions of rotation. For this purpose, a mirror-symmetrical inclination sensor / inclination switch NS was created for two axes crossing at right angles 2 is shown schematically. With the same radio transmitter module FS as that for door handles TG off 1 For example, the inclination sensor NS is to be understood as a square standing in a karo-like manner on each of its 4 corners, as essentially in the four mentioned angular positions of the window handle FG. As 2 can be seen, each inner corner of the square is provided with a contact pin KS, which closes with the gravitationally always located in the bottom of the square, metallic ball KU and the square housing QG an electrical contact EK.

In 2 It is noticeable that said 4 contacts EK / KS have only 3 supply lines ZL to the radio transmitter module FS. This is simply because a horizontal left or right window handle has the same detection signal. Therefore, these two electrical contacts EK / KS are interconnected by default.

In the 2 schematically shown monitoring device ÜV is in 3 shown as an experimentally implemented module (without interconnection). Therein, the square housing (QG) is sunk with its parallel to the axis of rotation of the window handle FG center axis on the broad side of a housing squeaker GQ of electrically non-conductive material. The open side of the housing squared is covered by an electrically conductive cover plate AB (flush-mounted). This creates for the metallic ball KU a ball cage within which it closes an electrical contact between the 4 pins KS and the cover AB in each of the 2 vertical and 2 horizontal window handle positions. For this purpose, it rolls on rotation of the window handle FG on one of the four radial inner walls of the square housing QG down and takes in their respective deepest corner a stable balance!

If the radio transmitter module FS is interconnected with the inclination sensor NS housed in the housing block GQ for the monitoring device UV, an independent and slim functional unit arises. This will be in an in 3 shown, and used to bypass the Faraday effect non-metallic housing tube GT before this is rotationally and axially fixed in the usually made of tubular steel window handle stub FL is inserted. The aesthetically pleasing, elliptical parting line between housing tube GT and window handle stub FL of this embodiment is not randomly chosen: On the one hand, it ensures the functionally correct, substantially vertical orientation of the square housing (QG) in the known as the "switching ball" (KU) as free as possible, gravity following, should fall and On the other hand, the antenna AT needs the largest possible, unimpeded by metal beam angle.

Another embodiment of window handles FG shows 4 , Here is the square case QG off 2 executed as easily manufacturable circular cylinder KZ.

A preferred embodiment for window handles FG is in 5 can be seen: Here are the 4 in the inclination sensor NS for window handles FG previously described, open and therefore prone to corrosion, electrical contacts EK / KS designed as hermetically sealed reed contacts RK. To actuate it requires a magnet, which in the embodiment of 5 is designed as a circular cylindrical permanent magnet PM. This is therefore relevant to the invention required, since the two magnetic poles of a disc-shaped or cylindrical permanent magnet lie on its end faces and thus its magnetic field structure is just as rotationally symmetric as the permanent magnet PM itself. This is essential because when rolling the magnetic disc or roller PM im square housing QG or circular cylinder KZ of inclination sensor NS whose angular position arbitrarily sets. This is also the case when the circular-cylindrical permanent magnet PM is used as the core in a thick-walled, non-magnetic (brass) tube identical axis. Thus, a relatively large weight of the loose "switch body" is achieved at a relatively small magnetic field strength. The purpose of this is that the weight of the permanent magnet PM including brass shell is greater than the magnetic switching force, and prevents the permanent magnet PM unintentionally "sticking" to a reed contact RK.

The same purpose serves the embodiment in 6 Here, a permanent magnet PM is arranged in a gravity pendulum SP, which is rotatably mounted on a rotation axis DA in the center of the circular cylinder pocket KZ. This design allows a specific shape and position of the permanent magnet PM to the reed contacts RK, since the permanent magnet PM designally always maintains its radial orientation to the axis of rotation DA.

A particularly elegant arrangement of the reed contacts RK shows the embodiment of 7 : In the upper half of the picture is the open front of the housing block GQ off 3 seen. Deviating from this 7 in the square housing QG ("ball cage") no switching ball KU, but a roller or disc-shaped permanent magnet PM. Therefore, also pins KS in the square housing QG are unnecessary. Rather, the magnetic field lines of the permanent magnet PM penetrate (axially) the antimagnetic bottom wall BW of the square housing QG and emerge on the back of the housing squeaker GQ. There they "switch" the in the lower half of 7 apparent 3 reed contacts. It has proved to be particularly advantageous in terms of size and function in the experimental phase, when a reed contact RK, which detects the two horizontal window handle positions, is arranged vertically and for the two vertical window handle positions depending on a reed contact RK horizontally in the housing block GK across is used. This attractive and invention-relevant arrangement benefits from two peculiar boundary conditions: On the one hand, reed contacts RK are common, which are characterized by the property of being magnet-sensitive only at their two ends. On the other hand, as already mentioned, the two horizontal angular positions of the window handles FG need not be distinguished sensory. Therefore, the corresponding pins KS are the 2 to 4 or reed contacts RK the 5 and 6 connected in parallel! The functional characteristic of named reed contacts RK now allows, due to their double-sided switching sensitivity, to capture both horizontal window handle positions with a single reed contact RK! The other two reed contacts RK are - as in the lower half of 7 can be seen - (longitudinally) arranged so that the oriented towards the center of the housing block GQ 4 reed-contact ends form a square substantially and are arranged quite congruent with the 4 corners of the square housing recess QG.

Since the bottom wall BW is mechanically impermeable and the cover plate AB closes the square housing QG including therein permanent magnet PM absolutely tight, forms the design of the embodiment 7 a hermetically sealed and therefore permanently pollution-proof and therefore maintenance-free and durable inclination sensor NS for window handles FG, which is also suitable due to its slim design together with the radio transmitter module FS as monitoring device ÜV for inconspicuous installation in hollow handles, which aesthetically elegant designs of the overall assembly including extremely flat, because independent, fitting plates / base plates allowed!

A foreseeable embodiment uses instead of the previously described and designed as an electrical switch inclination sensors NS graphically not shown magnetic flux sensors or so-called. Micromechanical gyroscopes, which are designed as mechatronic chips and the genus MEMS (Micro-Electro-Mechanical Systems) are assigned. The same applies to their successor generation, the so-called NEMS (Nanoelectromechanical Systems).
