Description

FunktelefonhandgerätHandheld radio telephone
Die Erfindung bezieht sich auf ein Funktelefonhandgerät mit einem Gehäuse für Sende/Empfangsteil, Steuerlogik, Batterie, etc. welches ein Eingabefeld, gegebenenfalls eine Anzeigeeinheit, ein Mikrofon, eine Hörkapsel etc. aufweist, bei welchem eine Antenne beweglich mit dem Gehäuse verbunden ist, und das Gehäuse zumindest einen Klapp/Schiebeteil besitzt, der im Be- triebszustand des Gerätes aufgeklappt oder aufgeschoben, sonst jedoch bei Verringerung der Gesamtabmessungen eingeklappt oder eingeschoben ist.The invention relates to a radio telephone handheld device with a housing for transmitting / receiving part, control logic, battery, etc., which has an input field, optionally a display unit, a microphone, an earphone, etc., in which an antenna is movably connected to the housing, and the housing has at least one folding / sliding part, which is opened or pushed open when the device is in operation, but is otherwise folded in or pushed in when the overall dimensions are reduced.
Die Entwicklung von Handgeräten für den Mobilfunk, umgangssprachlich "Handy" genannt, läuft noch immer in Richtung ei- ner weiteren Miniaturisierung, sodaß die Geräte immer kleiner werden. Um den Abstand zwischen Mikrofon und Hörkapsel den tatsächlichen anatomischen Gegebenheiten, nämlich dem Abstand zwischen Ohr und Mund eines Benutzers, anzupassen, sind bei sehr kleinen Geräten Ausklappbügel, Schieber oder Klappen vorgesehen, die das Mikrofon enthalten, wobei im ausgeklappten Zustand der Abstand Mikrofon-Hörkapsel das erforderliche Maß besitzt.The development of handheld devices for mobile radio, colloquially called "mobile phone", is still going in the direction of further miniaturization, so that the devices are getting smaller and smaller. In order to adapt the distance between the microphone and the earpiece to the actual anatomical conditions, namely the distance between the ear and mouth of a user, fold-out brackets, slides or flaps are provided in very small devices, which contain the microphone, the distance between the microphone and the earpiece being in the extended state has the required measure.
Antennen von Mobilfunkhandgeräten sind üblicherweise rechts oben an dem Handgerät angeordnet, entweder auf die volle Länge ausziehbar oder als elektrisch verkürzte Kurzantenne ausgebildet und oft abschraubbar. Unter schlechten Empfangsbedingungen sollte die Antennenlänge ihre optimale Größe besitzen, d. h. der Frequenz entsprechend und an den Eingangskreis angepaßt. Der Benutzer achtet oft nicht darauf, die Antenne auszuziehen, sodaß er dann nicht erreichbar ist. Weiters laufen derzeit nach wie vor Diskussionen über eine mögliche Gesundheitsgefährdung durch die Abstrahlung der HF-Energie im Sendebetrieb in unmittelbarer Gehirn/Augennähe. Eine Aufgabe der Erfindung liegt darin, die durch die zunehmende Miniaturisierung auftretenden technischen Probleme, wie z. B. die oben beschriebenen, zu beseitigen oder zu mindern.Antennas of mobile radio handheld devices are usually arranged at the top right of the handheld device, either extendable to their full length or designed as an electrically shortened short antenna and often unscrewable. Under poor reception conditions, the antenna length should have its optimal size, that is, according to the frequency and adapted to the input circuit. The user often does not pay attention to pulling out the antenna so that he is then unreachable. Furthermore, discussions about a possible health hazard due to the radiation of the RF energy in the transmission mode in the immediate vicinity of the brain / eyes are still ongoing. An object of the invention is to solve the technical problems arising from increasing miniaturization, such as e.g. B. to eliminate or reduce those described above.
Die Aufgabe wird, ausgehend von einem Funktelefonhandgerät der eingangs zitierten Art, erfindungsgemäß dadurch gelöst, daß die Antenne in den Klapp/Schiebeteil integriert ist.The task is, based on a radio telephone handset of the type mentioned, achieved according to the invention in that the antenna is integrated in the folding / sliding part.
Die Erfindung ermöglicht es auf einfache Weise, eine Anzahl von Vorteilen zu erreichen. Beispielsweise ist in den meisten Fällen eine bessere Abstrahlung der Sendeleistung möglich, Hirn und Auge liegen nicht mehr im unmittelbaren Abstrah- lungsbereich der Antenne und ein Ausziehen der Antenne entfällt bzw. wird dieses oder eine äquvialente Handlung (Aufklappen) automatisch bei Inbetriebnahme des Gerätes durchgeführt. Weiters ist die Antenne als solche überhaupt nicht mehr sichtbar.The invention enables a number of advantages to be achieved in a simple manner. In most cases, for example, better transmission of the transmission power is possible, the brain and eyes are no longer in the direct radiation range of the antenna and pulling out the antenna is no longer necessary or this or an equivalent action (opening) is carried out automatically when the device is started up. Furthermore, the antenna as such is no longer visible at all.
Die Erfindung samt ihren weiteren Vorteilen ist im folgenden an Hand von Ausführungsbeispielen näher erläutert, die in der Zeichnung veranschaulicht sind. In dieser zeigenThe invention and its further advantages are explained in more detail below with reference to exemplary embodiments which are illustrated in the drawing. In this show

Gemäß Fig. 1 besitzt ein Mobilfunkhandgerät nach der Erfin- düng in üblicher Weise ein Gehäuse 2, welches Sende- und Empfangsteil, die Steuerlogik, die Batterie etc. umschließt. Weiters ist ein Eingabefeld 3 vorgesehen, im allgemeinen die übliche Tastatur für Wahl- und Befehlseingabe, in den meisten Fällen eine Anzeigeeinheit 4 sowie eine Hörkapsel 5 oder Lautsprecher.1, a mobile radio handset according to the invention has a housing 2 in a conventional manner, which encloses the transmitting and receiving part, the control logic, the battery, etc. Furthermore, an input field 3 is provided, generally the usual keyboard for dialing and entering commands, in most cases a display unit 4 and an earphone 5 or loudspeaker.
Seitlich, hier an der rechten Seite, ist um eine Achse 6 verschwenkbar ein Stab 7 angelenkt, der an seinem äußeren Ende ein Mikrofon 8 trägt. In den Stab 7 ist weiters die strichliert, nur symbolisch angedeutete Antenne 9 des Gerätes integriert, was auf unterschiedliche Weise erfolgen kann. Beispielsweise kann der Stab aus einem Metallrohr bestehen und gegebenenfalls mit Kunststoff ummantelt sein, wobei die Verbindungsleitung zum Mikrofon 8 im Inneren des Metallrohres verläuft. Andererseits könnte bei Verwendung eines KunststoffStabes die Mikrofonzuleitung auch die Antenne bilden. Hiefür geeignete Ein- und Auskoppelungstechniken sind dem Fachmann bekannt .Laterally, here on the right side, a rod 7 is pivotally pivoted about an axis 6 and carries a microphone 8 at its outer end. In the rod 7, the dashed, only symbolically indicated antenna 9 of the device is integrated, which can be done in different ways. For example, the rod may consist of a metal tube and may be coated with plastic, the connection line to the microphone 8 running inside the metal tube. On the other hand, if a plastic rod is used, the microphone lead could also form the antenna. Suitable coupling and decoupling techniques are known to the person skilled in the art.
Der Stab 7 ist in Fig.l in seiner Betriebslage gezeigt, in welcher der Abstand zwischen Hörkapsel 5 und Mikrofon 8 ausreichend groß ist. Wird das dargestellte Gerät in der linken Hand gehalten, so ergibt sich die maximal mögliche Entfernung zwischen Antenne 9 und Kopf des Benutzers. Bei einer Rechts- handerausführung sollte der Stab 7 mit Mikrofon 8 und Antenne 9 an der - von vorne gesehen- rechten Geräteseite angelenkt sein.The rod 7 is shown in Fig.l in its operating position, in which the distance between the earpiece 5 and microphone 8 is sufficiently large. If the device shown is held in the left hand, the maximum possible distance between the antenna 9 and the head of the user results. In a right-hand version, the rod 7 with the microphone 8 and antenna 9 should be articulated on the right-hand side of the device when viewed from the front.
Wird das Gerät 1 außer Betrieb genommen, so kann der Stab 7 um die Achse 6 so zurückgeschwenkt werden, daß er an der Seitenwandung des Gehäuses 2 anliegt. Um den Stab 7 besser zu schützen, könnte er in der Außerbetriebstellung in einem schmalen Fach des Gehäuses aufgenommen sein, falls das Gehäuse entsprechend erweitert ist.If the device 1 is taken out of operation, the rod 7 can be pivoted back about the axis 6 so that it rests on the side wall of the housing 2. In order to better protect the rod 7, it could be in the inoperative position in one narrow compartment of the housing, if the housing is expanded accordingly.
Die Ausführung nach Fig.2 zeigt einen in einer Aufnahme 10 des Gehäuses 2 verschiebbar gelagerten Stab 7, der im Prinzip dem in Fig.l beschriebenen Stab - mit Mikrofon 8 und Antenne 9 - entspricht, weshalb gleiche Bezugsszeichen verwendet werden. Der Stab 7 kann gegen die Kraft einer Feder 11 vollständig in die Aufnahme 10 des Gehäuses 2 geschoben werden und in dieser Außerbetriebslage durch eine Verrastung gehalten sein, die beispielsweise aus einer Nut 12 in dem Stab 7 und einer in diese Nut eingreifenden Verriegelungsklinke 13 besteht. Diese Klinke kann mit einer kleinen Feder 14 belastet sein und durch einen Auslöseknopf 15 am Eingabefeld 3 über eine strichliert gezeichnete mechanische Verbindung 16 abgehoben werden, sodaß der Stab 7 dann selbsttätig ausfährt.The embodiment according to FIG. 2 shows a rod 7 slidably mounted in a receptacle 10 of the housing 2, which in principle corresponds to the rod described in FIG. 1 - with microphone 8 and antenna 9 - which is why the same reference numerals are used. The rod 7 can be pushed completely against the force of a spring 11 into the receptacle 10 of the housing 2 and can be held in this inoperative position by a catch, which consists, for example, of a groove 12 in the rod 7 and a locking pawl 13 engaging in this groove. This pawl can be loaded with a small spring 14 and lifted by a release button 15 on the input field 3 via a mechanical connection 16 shown in broken lines, so that the rod 7 then extends automatically.
Bei einer anderen, in Fig.3 gezeigten Ausführung besitzt das Handgerät 1 einen flächigen Abdeckteil 17 , der um eine Schwenkachse 18 so klapp- bzw. verschwenkbar ist, daß in einer Außerbetriebsstellung (nicht gezeigt) die gesamte Vorderfront des Gehäuses 2 abgedeckt ist, wogegen in der dargestellten Betriebsstellung der Abdeckteil 17 quasi eine Verlängerung des Gehäuses 2 darstellt, in deren unteren Bereich das Mikrofon 8 sitzt. Bei dieser Ausführungsform kann die strichliert gezeichnete Antenne 9 beispielsweise ein Metallstreifen sein. Gegebenenfalls kann auch eine zweite Antenne 9a in dem Abdeckteil 17 integriert sein, um die Empfangsleistung zu verbessern. Schaltungen zur Verarbeitung der Signale von zwei Antennen zur Verbesserung der Empfangsleistung bei ständigem Ortswechsel der Antennen sind bekannt, beispielsweise in der Autoradiotechnik.In another embodiment, shown in FIG. 3, the hand-held device 1 has a flat cover part 17 which can be pivoted or pivoted about a pivot axis 18 such that the entire front face of the housing 2 is covered in an inoperative position (not shown), whereas in the operating position shown, the cover part 17 represents an extension of the housing 2, in the lower area of which the microphone 8 is seated. In this embodiment, the antenna 9 shown in broken lines can be a metal strip, for example. If necessary, a second antenna 9a can also be integrated in the cover part 17 in order to improve the reception performance. Circuits for processing the signals from two antennas to improve the reception performance when the antennas are constantly changing are known, for example in car radio technology.
Eine Variante der Ausführung nach Fig.3 ist in Fig.4 skiz- ziert, bei welcher zwei um Achsen 18, 18a schwenkbare Abdeckteile 17 und 17a vorgesehen sind. Bei dieser Ausführung kann der Abdeckteil 17 genau so ausgebildet sein wie jener nach Fig.3, wobei dem Abdeckteil 17a eine reine Abdeckfunktion zukommt. Allerdings ist es auch möglich, in dem (oberen) Abdeckteil 17a die Hörkapsel unterzubringen und in dem (unteren) Abdeckteil 17 das Mikrofon. Die Antenne 9 (strichliert) kann in den Abdeckteil integriert sein. Andererseits könnte der (obere) Abdeckteil 17a auch lediglich eine Antenne beinhalten oder als solche, nämlich als Flächenantenne ausgebildet sein. Der bei den übrigen Ausführungen genannte Vorteil einer großen Entfernung zwischen Antenne und Kopf des Benutzers ist dabei allerdings nicht gegeben, was in Fällen mit geringer Sendeleistung, z.B. in DECT-Geräten, aber nicht ins Gewicht fällt.A variant of the embodiment according to FIG. 3 is outlined in FIG. 4, in which two cover parts 17 and 17a, which can be pivoted about axes 18, 18a, are provided. In this embodiment, the cover part 17 can be designed exactly like that after 3, wherein the cover part 17a has a purely covering function. However, it is also possible to accommodate the earpiece in the (upper) cover part 17a and the microphone in the (lower) cover part 17. The antenna 9 (dashed lines) can be integrated in the cover part. On the other hand, the (upper) cover part 17a could also contain only one antenna or be designed as such, namely as a surface antenna. However, the advantage of a large distance between the antenna and the head of the user, which is mentioned in the other embodiments, does not exist, which is not important in cases with low transmission power, for example in DECT devices.
Bei der Variante nach Fig.5 ist der Abdeckteil für das Gehäu- se als Schiebedeckel 19 ausgebildet. Dieser kann in hier nicht näher gezeigten Führungen, z.B. in Längsnuten, seitlich oder an der Vorderfront des Gehäuses 2 verschieblich geführt sein, nämlich aus einer, die gesamte Vorderfront (oder einen Teil derselben) abdeckenden Außerbetriebsstellung in eine Be- triebsstellung, in welcher der Abstand zwischen einem in den Deckel 19 eingebauten Mikrofon 8 und der Hörkapsel 5 ausreichend groß ist. Die Antenne 9 ist in den Schiebedeckel integriert, beispielsweise in eine von zwei seitlichen Wangen 19a, da sich hier eine gute Kontaktierungsmöglichkeit für die Antenne ergibt.In the variant according to FIG. 5, the cover part for the housing is designed as a sliding cover 19. This can be in guides not shown here, e.g. be guided in longitudinal grooves, laterally or on the front of the housing 2, namely from an inoperative position covering the entire front (or a part thereof) into an operating position in which the distance between a microphone 8 and the earphone 5 is sufficiently large. The antenna 9 is integrated in the sliding cover, for example in one of two side cheeks 19a, since this provides a good possibility of contacting the antenna.
Die Erfindung läßt sich auf sämtliche Mobilfunkhandgeräte anwenden, beispielsweise auf solche im GSM oder DECT-System arbeitende, jedoch prinzipiell auf Sprechfunkgeräte, die in ei- nem Frequenzbereich arbeiten, der Antennenabmessungen im Sinne der Erfindung ermöglicht. The invention can be applied to all mobile radio handheld devices, for example to those operating in the GSM or DECT system, but in principle to walkie-talkies which operate in a frequency range which enables antenna dimensions in the sense of the invention.
