advantageous Embodiments of the invention are characterized in the subclaims.

The Invention will be described below with reference to the drawing Embodiments explained. It demonstrate:

1 a perspective view of a bottom plate of a wireless adapter,

2 . 3 Components of a radio adapter in two perspectively different "exploded views",

4 a mounted wireless adapter,

5 Building components of a wireless adapter in "exploded view".

In 5 construction components of a wireless adapter are shown in an "exploded view" The wireless adapter 26 has an adapter housing (plastic housing) with one on a bottom plate (see paragraph 1 in the 1 . 2 . 3 ) snap-on lid 6 on. On the bottom plate essential components, in particular a printed circuit board are mounted, as described in detail below. For the power supply of the electrical / electronic components of the wireless adapter 26 is preferably one in a battery receiving compartment 9 insertable battery 11 (or accumulator), wherein the battery receiving compartment 9 by means of a battery compartment lid 10 is closable. The battery 11 is very easy to change from the outside bar. To pass through a handle actuating bolt (see paragraph 28 in 4 ) is the lid with a hole 7 Mistake. To the wireless adapter 26 To attach to a door leaf or window frame is the lid 6 with two holes 8th provided by which handle fixing screws can be guided.

• • mehrere Rastzapfen 2 zur Verrastung mit dem Deckel 6 (wobei die Rast- zapfen in korrespondierende Rastnuten des Deckels 6 eingreifen),
• • Bohrungen 4 zum Durchgriff von Griff-Befestigungsschrauben (korrespondierend zu den Bohrungen 8 des Deckels 6),
• • mehrere Haltezapfen 5 für die Befestigung einer Leiterplatte 12,
• • Batterie-Kontaktlaschen 16, 17 zur Kontaktierung der Batterie 11.

In 1 is a perspective view of a bottom plate of a wireless adapter shown. The bottom plate 1 indicates:

• • several locking pins 2 for locking with the lid 6 (wherein the locking pin in corresponding locking grooves of the lid 6 intervention),
• • Drilling 4 for the passage of handle fixing screws (corresponding to the holes 8th of the lid 6 )
• • several retaining pins 5 for the attachment of a printed circuit board 12 .
• • Battery contact lugs 16 . 17 for contacting the battery 11 ,

• • zwei sich direkt gegenüberliegende Reedkontakte 13, 14,
• • ein drehbewegliches Schaltrad 18, welches zentral eine Ausnehmung 21 entsprechend dem Vierkantprofil eines Griff-Betätigungsbolzens (siehe Ziffer 28 in 4) aufweist und mit einer Magnetträgertasche 19 zur Aufnahme eines Permanentmagneten 20 versehen ist,
• • eine Auswerteelektronik 24 inklusive Funksendemodul (die zugehörige Antenne ist nicht zu erkennen).

On the circuit board 12 are mounted:

• • two directly opposite reed contacts 13 . 14 .
• • a rotatable ratchet wheel 18 which central a recess 21 according to the square profile of a handle-actuating bolt (see paragraph 28 in 4 ) and with a magnetic carrier bag 19 for receiving a permanent magnet 20 is provided
• • an evaluation electronics 24 including radio transmitter module (the associated antenna is not visible).

In the 2 and 3 construction components of a wireless adapter are shown in two perspectively different "exploded views." It can be seen that the ratchet wheel 18 via bottom-side locking means 23 in a provided for the passage of the handle actuating bolt hole 3 (in the bottom plate 1 and in the circuit board 12 ) can engage in a snap. The assembly of the permanent magnet 20 takes place in a very simple manner by plugging in the magnet carrier bag 19 , This mounting method is more advantageous than gluing. The two reed contacts 13 . 14 are oblique, ie rotated by an angle of about 45 ° with respect to the orientation of the permanent magnet 20 on the circuit board 12 This ensures that the reed contact does not switch twice, but only once, as soon as it comes off the permanent magnet 20 is swept over. Furthermore, these are between the battery contact tabs 16 . 17 formed battery storage compartment 9 and the transmitter 24 shown.

In 4 a mounted wireless adapter is shown. As can be seen, engages the already mentioned several times handle actuating pin 28 in a shutter mechanism 30 a door leaf 29 , A turn of the window or door handle 27 is the handle between 27 and door leaf 29 mounted radio adapter 26 recorded and reported by radio signal to an external receiving and evaluation unit.

As already apparent from the above description, the bore is used 3 for rotatably supporting the ratchet wheel 18 , A the bore 3 enclosing ring on the circuit board 12 serves as a defined sliding surface with respect to the underside of the ratchet wheel 18 , End-side locking lugs of the locking means 23 prevent falling out of the switching wheel 18 , Usually, the window handle shows 27 with the window closed down and with the window tilted up, while the window is open, as soon as the window handle 27 in horizontal position (middle position). Accordingly, three different grip positions or states can be defined and detected:

Condition "closed":

The permanent magnet 20 is located above the reed contact 13 , The reed contact 13 is therefore closed, ie it flows by means of the evaluation 24 detected, small contact current via the switching contacts of the reed contact 13 ,

State "opened":

The permanent magnet 20 is in the position between both reed contacts 13 . 14 , Neither reed contact 13 still reed contact 14 is closed, ie the transmitter 24 detects no contact current.

Condition "tilted":

The permanent magnet 20 is located above the reed contact 14 , The reed contact 14 is therefore closed, ie it flows by means of the evaluation 24 detected, small contact current via the switching contacts of the reed contact 14 ,

The evaluation electronics 24 converts depending on the position or position of the ratchet wheel 18 and thus the window or door handle 27 generated electrical signals in radio signals, which on one on the circuit board 12 mounted antenna to an external, for evaluating the current window or door handle position (position) serving radio receiver of a central station (such as a wireless alarm system) are radiated so wirelessly to signal that the sash or the door leaf is open or closed or tilted ,

To change position (state change sel) also directly on the radio adapter 26 can display a light emitting diode on the circuit board 12 be attached, with the lid 6 of the adapter housing is provided with an opening in order to be able to recognize the current grip position on the basis of the color of the light-emitting diode (eg light-emitting diode lights up red: door or window open / light-emitting diode lights up green: door or window closed).

To indicate a required battery change (or a required recharge of a battery), a light emitting diode on the circuit board 12 be attached, with the lid 6 of the adapter housing is provided with an opening in order to be able to recognize the instantaneous lighting status (eg LED flashes: change battery / light-emitting diode off: battery capacity is still sufficient) of this light-emitting diode.
