Description

Stand der TechnikState of the art

Die Erfindung geht von einem Sende/Empfänger nach der Gattung des Patentanspruchs 1 aus.The invention is based on a transceiver according to the preamble of claim 1.

Aus den «Patents Abstracts of Japan», Bd. 3, Nr. 96, 15. August 1979, Seite 71 E 130, ist ein Funkgerät bekannt, das einen länglichen Schutzdeckel aufweist, der in einer ersten Stellung eine die Bedienungselemente tragenden Stirnseite des Funkgerätegehäuses bedeckt und in einer zweiten durch paralleles Verschieben zu der genannten Stirnseite erreichten Stellung als Antenne wirkt. Weiterhin sind Funkgeräte bekannt, bei denen eine Antenne durch eine in einem Uhrarmband eingesetzte Ferritantenne (DE-B-1416084), durch eine in einem Tragriemen untergebrachte Antenne (DE-U-1807959) oder durch Teile des Funkgerätegehäuses (DE-B-2153827) gebildet wird.From the “Patents Abstracts of Japan”, Vol. 3, No. 96, August 15, 1979, page 71 E 130, a radio device is known which has an elongated protective cover which, in a first position, has an end face of the radio device housing which carries the operating elements covered and acts as an antenna in a second position achieved by parallel displacement to the aforementioned end face. Furthermore, radio devices are known in which an antenna is used by a ferrite antenna inserted in a watch band (DE-B-1416084), by an antenna housed in a carrying strap (DE-U-1807959) or by parts of the radio device housing (DE-B-2153827) is formed.

Vorteile der ErfindungAdvantages of the invention

Der erfindungsgemässe Sender/Empfänger mit einer Antenne entsprechend den kennzeichnenden Merkmalen des Patentanspruchs 1 hat demgegenüber den Vorteil, dass als Antenne ein ohnehin am Empfänger vorhandenes Element, nämlich der zur Halterung des Empfängers in der Jackentasche vorgesehene Clip, verwendet wird. Hierdurch ist keine zusätzliche Antenne mehr erforderlich; damit werden die Herstellungskosten des Empfängers gesenkt.The transmitter / receiver according to the invention with an antenna according to the characterizing features of claim 1 has the advantage that an antenna that is already present on the receiver, namely the clip provided for holding the receiver in the jacket pocket, is used as the antenna. As a result, no additional antenna is required; this reduces the manufacturing costs of the receiver.

Durch die in den Unteransprüchen aufgeführten Massnahmen sind vorteilhafte Weiterbildungen der im Hauptanspruch angegebenen Antenne möglich. So ist es besonders vorteilhaft, dass der Clip erst in seiner hochgeklappten Arbeitsstellung mit dem Antennenausgang verbunden wird und dabei gleichzeitig eine Schaltfunktion, beispielsweise zur Aktivschaltung der Sendetaste, ausübt.The measures listed in the subclaims permit advantageous developments of the antenna specified in the main claim. It is particularly advantageous that the clip is only connected to the antenna output in its folded-up working position and at the same time performs a switching function, for example for activating the transmit button.

Zeichnungdrawing

Die Erfindung ist in der Zeichnung dargestellt und in der nachfolgenden Beschreibung nähererläutert. Es zeigen:

  • Fig. 1a bis 1c eine erste Ausführungsform einer erfindungsgemässen Antenne in mehreren Betriebsstellungen;
  • Fig. 2a bis 2c eine zweite Ausführungsform einer erfindungsgemässen Antenne in mehreren Betriebsstellungen.
The invention is illustrated in the drawing and explained in more detail in the following description. Show it:
  • 1a to 1c a first embodiment of an antenna according to the invention in several operating positions;
  • 2a to 2c a second embodiment of an antenna according to the invention in several operating positions.

Beschreibung der AusführungsbeispieleDescription of the embodiments

In Fig. 1a ist mit 11 ein tragbarer Personenruf-Senderempfänger bezeichnet, der einen an sich bekannten Clip 10 aufweist, der in seiner Ruhestellung elastisch am Empfänger 11 anliegt. Der Clip 10 dient dazu, den Empfänger 11 in der Jakkentasche oder dergleichen des Benutzers zu halten. Der Clip 10 ist über ein Gelenk 12 mit dem Empfänger 11 verbunden, wobei ein in der Zeichnung nicht dargestellter Nocken mit einer Feder die Rückstellkraft des Clips 10 erzeugt. Wie in Fig. 1 b dargestellt, kann der Clip 10 jedoch gegen diese Federkraft ausgelenkt werden und gelangt, wie in Fig. 1c dargestellt, hochgeklappt in seine Arbeitsstellung als Antenne. In dieser Stellung gelangt der Clip 10 nämlich in Kontakt mit einem Antennenanschluss 13 des Senderempfängers 11 und kann nun als Sende/Empfangsantenne verwendet werden. In einer vorteilhaften Ausgestaltung der Erfindung bewirkt ein Hochklappen des Clips 10 entsprechend Fig. 1 c gleichzeitig die Betätigung eines weiteren elektrischen Kontaktes, der vorzugsweise eine Aktivschaltung der Sendetaste des Empfängers 11 bewirkt. Auf diese Weise wird sichergestellt, dass die Sendetaste nur bei hochgeklapptem Clip 10, das heisst bei betriebsbereiter Antenne, möglich ist. Selbstverständlich ist es möglich, bei der Formgebung des Clips 10 dessen Funktion als Antenne derart zu berücksichtigen, dass der Clip 10 beispielsweise die Funktion einer Verlängerungsspule zur Erzielung einer günstigeren HF-Abstrahlung erhält.In Fig. 1a, 11 is a portable pager transceiver, which has a known clip 10, which rests elastically on the receiver 11 in its rest position. The clip 10 serves to hold the receiver 11 in the user's Jakkentasche or the like. The clip 10 is connected to the receiver 11 via a joint 12, a cam (not shown in the drawing) with a spring generating the restoring force of the clip 10. As shown in FIG. 1 b, the clip 10 can, however, be deflected against this spring force and, as shown in FIG. 1 c, reaches its working position as an antenna when folded up. In this position, the clip 10 comes into contact with an antenna connection 13 of the transceiver 11 and can now be used as a transmitting / receiving antenna. In an advantageous embodiment of the invention, folding up the clip 10 according to FIG. 1 c simultaneously causes the actuation of a further electrical contact, which preferably brings about an activation of the transmit button of the receiver 11. This ensures that the send button is only possible when the clip 10 is folded up, that is to say when the antenna is ready for operation. Of course, it is possible to take into account the function of the clip 10 when shaping the clip in such a way that the clip 10 has, for example, the function of an extension coil to achieve a more favorable RF radiation.

Andererseits ist es selbstverständlich, insbesondere bei Handsprechfunkgeräten, möglich, die Ruhestellung des Clips für den Empfang zu nutzen, indem erfindungsgemäss der Clip 10 in Ruhestellung an einen in der Zeichnung nicht dargestellten Antenneneingang des Empfängers 11 angeschlossen wird und weiterhin einen Kontakt in Ruhestellung schliesst, der eine Aktivschaltung der Empfangsbereitschaft bewirkt.On the other hand, it is of course possible, in particular in the case of walkie-talkies, to use the rest position of the clip for reception, in that, according to the invention, the clip 10 is connected in the rest position to an antenna input of the receiver 11, not shown in the drawing, and continues to close a contact in the rest position, which activating the readiness to receive.

Während bei dem Ausführungsbeispiel entsprechend den Fig. 1 bis 1 der Clip 10 wenigstens näherungsweise die Form eines schmalen Federelementes hat, ist in den Fig. 2a bis 2c eine weitere Ausführungsform einer erfindungsgemässen Antenne dargestellt, bei der auf einem Empfänger 14 ein Clip 15 angeordnet ist, der die Gestalt einer flächigen Feder hat. Die Umschwenkung des Clips 15 entsprechend den Fig. 2b und 2c erfolgt dabei nicht senkrecht zur Rückwand des Empfängers 14, sondern in derselben Ebene. Ansonsten ist die Funktion des Clips 15 einerseits als Halteelement in Ruhestellung und andererseits als Antenne in Arbeitsstellung dieselbe, wobei in bevorzugter Ausgestaltung der Erfindung auch beim Clip 15 die Kontaktierung mit einem Antennenausgang in der Arbeitsstellung und die Betätigung des weiteren Kontaktes vorgesehen ist.1 to 1, the clip 10 has at least approximately the shape of a narrow spring element, FIGS. 2a to 2c show a further embodiment of an antenna according to the invention, in which a clip 15 is arranged on a receiver 14 , which has the shape of a flat spring. The pivoting of the clip 15 according to FIGS. 2b and 2c does not take place perpendicular to the rear wall of the receiver 14, but in the same plane. Otherwise, the function of the clip 15 on the one hand as a holding element in the rest position and on the other hand as the antenna in the working position is the same, whereby in a preferred embodiment of the invention the contact with an antenna output in the working position and the actuation of the further contact is also provided for the clip 15.
