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

In Fig. 5, construction components of a wireless adapter in "exploded view" are shown. The radio adapter 26 has an adapter housing (plastic housing) with a on a bottom plate (see paragraph 1 in Figs. 1, 2, 3) latched lid 6. 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 used in a battery receiving tray 9 insertable battery 11 (or accumulator), wherein the battery receiving tray 9 is closed by means of a battery cover 10. The battery 11 is easily replaceable from the outside. For the passage of a handle actuating bolt (see paragraph 28 in Fig. 4), the lid is provided with a bore 7. To secure the radio adapter 26 to a door leaf or window frame, the cover 6 is provided with two holes 8 through which handle fixing screws can be passed.

• mehrere Rastzapfen 2 zur Verrastung mit dem Deckel 6 (wobei die Rastzapfen 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 Fig. 1 is a perspective view is shown on a bottom plate of a wireless adapter. The bottom plate 1 has:

• a plurality of latching pins 2 for latching to the cover 6 (the latching pins engaging in corresponding latching grooves of the cover 6),
• Holes 4 for the passage of handle mounting screws (corresponding to the holes 8 of the lid 6),
• a plurality of retaining pins 5 for the attachment of a printed circuit board 12,
• Battery contact lugs 16, 17 for contacting the battery 11th

• 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 Fig. 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 centrally has a recess 21 corresponding to the square profile of a handle actuating bolt (see paragraph 28 in Fig. 4) and is provided with a magnetic carrier pocket 19 for receiving a permanent magnet 20,
• an evaluation 24 including radio transmitter module (the associated antenna is not visible).

FIGS. 2 and 3 show structural components of a radio adapter in two perspective "exploded views". It can be seen that the ratchet wheel 18 via latching means 23 on the bottom side 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 latching. The assembly of the permanent magnet 20 is carried out in a very simple manner by insertion into the magnetic carrier pocket 19. This mounting method is more advantageous than gluing. The two reed contacts 13, 14 are oblique, d. H. rotated about an angle of about 45 ° with respect to the alignment of the permanent magnet 20 mounted on the circuit board 12, thereby ensuring that the reed switch not twice, but only once, as soon as it is swept by the permanent magnet 20. Furthermore, the battery receiving compartment 9 formed between the battery contact lugs 16, 17 and the evaluation electronics 24 are shown.

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

• Zustand "geschlossen":
  • Der Permanentmagnet 20 befindet sich über dem Reedkontakt 13. Der Reedkontakt 13 ist demzufolge geschlossen, d. h. es fließt ein mittels der Auswerteelektronik 24 detektierter, kleiner Kontaktstrom über die Schaltkontakte des Reedkontakts 13.
• Zustand "geöffnet":
  Der Permanentmagnet 20 befindet sich in der Position zwischen beiden Reedkontakten 13, 14. Weder Reedkontakt 13 noch Reedkontakt 14 ist geschlossen, d. h. die Auswerteelektronik 24 detektiert keinen Kontaktstrom.
• Zustand "gekippt":
  • Der Permanentmagnet 20 befindet sich über dem Reedkontakt 14. Der Reedkontakt 14 ist demzufolge geschlossen, d. h. es fließt ein mittels der Auswerteelektronik 24 detektierter, kleiner Kontaktstrom über die Schaltkontakte des Reedkontakts 14.

As already apparent from the foregoing description, the bore 3 serves for the rotatable mounting of the ratchet wheel 18. A ring enclosing the bore 3 on the circuit board 12 serves as a defined sliding surface relative to the underside of the ratchet wheel 18. End-side locking lugs of the locking means 23 prevent falling out of the ratchet wheel 18. Typically, the window handle 27 with the window closed down and tilted window up while the window is open when the window handle 27 is in a horizontal position (center 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, a small contact current detected by means of the evaluation electronics 24 flows via the switching contacts of the reed contact 13.
• State "opened":
  The permanent magnet 20 is in the position between the two reed contacts 13, 14. Neither reed contact 13 nor 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 accordingly closed, ie, a small contact current detected by means of the evaluation electronics 24 flows via the switching contacts of the reed contact 14.

The transmitter 24 converts the electrical signals generated as a function of the position or position of the switching wheel 18 and thus of the window or door handle 27 into radio signals, which via an antenna mounted on the circuit board 12 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 indicate a change of position (state change) also directly on the radio adapter 26, a light emitting diode may be mounted on the circuit board 12, wherein the lid 6 of the adapter housing is provided with an opening to the current grip position based on the color of the light emitting diode (z B. LED lights up red: door or window open / LED lights up green: door or window closed).

In order to indicate a required battery change (or required recharging of a battery), a light emitting diode may be mounted on the circuit board 12, with the cover 6 of the adapter housing being provided with an aperture to indicate the current light status (eg LED flashes: change battery / LED off: Battery capacity still sufficient) to recognize this LED.
