Description

Die vorliegende Erfindung betrifft ein batteriegespeistes bedienungsfreundliches, im Aufbau einfaches, leichtgewichtiges Hörgerät.The present invention relates to a battery-powered, user-friendly hearing aid that is simple in construction.

Hörgeräte müssen grundsätzlich möglichst klein sein. Ihre Entwicklung muss jedoch auch in Richtung einfachster Bedienung gehen, da deren Gebraucher im allgemeinen ältere Leute sind. Die einfache Bedienung derartiger Hörgeräte bringt es jedoch mit sich, dass auch Kinder leichten Zugriff im besonderen zu der Batterie derartiger Hörgeräte haben. Damit besteht die Gefahr, dass Kinder mit derartigen Batterien spielen und sie verschlucken, was zu grossen Schwierigkeiten für das Kind und den Hörgeräteinhaber führen kann.In principle, hearing aids must be as small as possible. However, their development must also go in the direction of simplest operation, since their users are generally older people. However, the simple operation of such hearing aids means that even children, in particular, have easy access to the battery of such hearing aids. There is therefore a risk that children play with such batteries and swallow them, which can lead to great difficulties for the child and the hearing aid owner.

Aufgrund dieser Sachlage bezweckt die vorliegende Erfindung die Schaffung eines batteriegespeisten Hörgerätes, welches im montierten betriebsfertigen Zustand den einfachen Zugriff zur Betriebsbatterie verunmöglicht, damit solche Hörgeräte batterieseitig dem Zugriff, insbesondere von Kleinkindern, entzogen sind.On the basis of this situation, the present invention aims to create a battery-powered hearing aid which, in the assembled, ready-to-use state, makes easy access to the operating battery impossible, so that such hearing aids are inaccessible to the battery, in particular by small children.

In diesem Sinne zeichnet sich die vorliegende Erfindung nach einem der Ansprüche aus.In this sense, the present invention is characterized according to one of the claims.

Die Erfindung wird anschliessend beispielsweise anhand einer Zeichnung erläutert.The invention is subsequently explained, for example, using a drawing.

Grundsätzlich ist festzuhalten, dass ein derartiges Hörgerät einfach zu handhaben sein muss und trotzdem bezüglich Sicherheit, Bedienung usw. eine optimale Ausführung verlangt. Dazu gehört auch die einfache Bedienung des Batteriewechsels, welche jedoch den Zugriff zur Batterie in eingebautem Zustand, insbesondere durch Kinder, verunmöglicht.Basically, it should be noted that such a hearing aid must be easy to use and still require optimal execution in terms of safety, operation, etc. This also includes the simple operation of the battery change, which, however, makes access to the battery in the installed state, especially by children, impossible.

Fig. 1 zeigt einen Teil 1 eines Hörgerätes mit einer Batterie 3, die in einer Batterieschublade 4 eingeschoben ist. Die Batterieschublade 4 weist eine Bohrung 5 auf, deren Schwenkachse mit 6 bezeichnet ist.Fig. 1 shows a part 1 of a hearing aid with a battery 3, which is inserted in a battery drawer 4. The Battery drawer 4 has a bore 5, the pivot axis of which is designated 6.

Die Batterieschublade 4 wird mitsamt der Batterie 3 durch zwei Gehäusehälften 7 und 8 abgedeckt. Die Batterieschublade 4 ist mit einem üblichen Verschluss 9 versehen, welcher zum Ausschwenken der Batterieschublade 4 um die Schwenkachse 6 betätigt wird und den Zugriff zur Batterie 3 erlaubt. Eine teilweise geöffnete Batterieschublade 4 ist in Fig. 3 ersichtlich.The battery drawer 4 is covered together with the battery 3 by two housing halves 7 and 8. The battery drawer 4 is provided with a conventional lock 9, which is actuated to pivot the battery drawer 4 out about the pivot axis 6 and allows access to the battery 3. A partially open battery drawer 4 can be seen in FIG. 3.

Fig. 4 zeigt eine Batterieschublade 4 mit einem teilweise zylinderförmigen Hohlraum zur Aufnahme der Batterie 3, welche auf einen Batterieauflagering 10 zum Aufliegen kommt. Dieser Auflagering 10 weist eine Sicherheitsverschlussausnehmung 11 auf sowie eine schlitzförmige Ausnehmung 19 und eine Haltenut 20, die, wie später erläutert, dem Oeffnen der Kindersicherung dienen.4 shows a battery drawer 4 with a partially cylindrical cavity for receiving the battery 3, which comes to rest on a battery support ring 10. This support ring 10 has a safety lock recess 11 as well as a slot-shaped recess 19 and a holding groove 20 which, as explained later, serve to open the child safety device.

Fig. 5 zeigt in perspektivischer Darstellung das Innere der Gehäusehälfte 7 mit einem Schwenkzapfen 12, welcher in die Bohrung 5 der Batterieschublade 4 eingreift sowie einen in eine Ausnehmung 15 einschiebbaren Sicherungsbolzen 14 mit einer Greifrille 16, welcher Bolzen 14 zu einem Sicherheitsverschluss gehört. Der Sicherungsbolzen 14 kann von einer Fachperson bei Bedarf einfach eingesetzt und dank seiner Greifrille auch wieder entfernt werden. Es ist ferner ein Fenster 18 der Gehäusehälfte 7 dargestellt. Was nun die erfindungsgemässe Kindersicherung, welche den Zugriff zur Batterie wesentlich erschweren soll, betrifft, wird diese anhand der folgenden Figuren erläutert. Dabei ist hervorzuheben, dass es sich um Ausführungsbeispiele und Möglichkeiten derartiger Sicherungen handelt, nicht um ausschliesslich machbare Konstruktionen.Fig. 5 shows a perspective view of the interior of the housing half 7 with a pivot pin 12 which engages in the bore 5 of the battery drawer 4 and a safety bolt 14 which can be inserted into a recess 15 and has a gripping groove 16, which bolt 14 belongs to a safety lock. The securing bolt 14 can easily be used by a specialist if required and can also be removed again thanks to its gripping groove. A window 18 of the housing half 7 is also shown. As for the child safety device according to the invention, which is intended to make access to the battery considerably more difficult, this is explained with reference to the following figures. It should be emphasized that these are exemplary embodiments and possibilities of such safeguards, not exclusively feasible constructions.

Fig. 6 zeigt analog der Fig. 3, aber mit abgehobener Gehäusehälfte 7, den fast geschlossenen, aber nicht kindergesicherten Zustand der Batterieschublade 4 (ohne Batterie). Da die Batterieschublade 4 bezüglich ihrer Schwenkachse 6 mit z.B. einem Druck in Pfeilrichtung zum Ueberstreifen eines Blockierzapfens 22, welcher dem Sicherungsbolzen 14 entspricht, elastisch deformiert werden muss, wird ein entsprechendes Material gewählt, oder eine entsprechende Biegestelle der Batterieschublade 4 durch eine Ausnehmung 19 des Batterieauflageringes 10 festgelegt. Damit wird es möglich, die Batterieschublade 4 über den Blockierzapfen 22 in Schliessstellung zu schieben, so dass die Sicherheitsverschlussausnehmung 11 den Blockierzapfen 22 formschlüssig umfasst, was ein Oeffnen der Batterieschublade 4 von aussen, trotz Betätigen des Verschlusses 9, verunmöglicht. Es kann natürlich anstelle der Batterieschublade der Blockierzapfen 22 elastisch deformierbar sein.Fig. 6 shows analogous to Fig. 3, but with the housing half raised 7, the almost closed, but not childproof condition of the battery drawer 4 (without battery). Since the battery drawer 4 must be elastically deformed with respect to its pivot axis 6, for example with a pressure in the direction of the arrow to slip over a locking pin 22, which corresponds to the securing bolt 14, a corresponding material is selected, or a corresponding bending point of the battery drawer 4 through a recess 19 in the battery support ring 10 set. This makes it possible to push the battery drawer 4 over the locking pin 22 into the closed position, so that the safety lock recess 11 encloses the locking pin 22 in a form-fitting manner, which makes it impossible to open the battery drawer 4 from the outside, despite actuation of the lock 9. Of course, instead of the battery drawer, the blocking pin 22 can be elastically deformable.

Fig. 8 zeigt einen derartigen Sicherheitsverschluss, der mit Hilfe eines Schraubendrehers 25 geöffnet werden kann. Zum Einführen dieses Schraubendrehers 25 ist eine Führungsnut 23 zwischen dem Verschluss 9 der Batterieschublade 4, 30 und der Wandgehäusehälfte 8 oder der Wandgehäusehälfte 7, oder beiden vorgesehen, durch welche das vordere Ende des Schraubendrehers 25 in der dargestellten Weise ins Innere der Batterieschublade 4 gelangt und durch Bewegung in Pfeilrichtung den Schubladensicherungsteil um die Ausnehmung 19 schwenkend in die in Fig. 6 dargestellte Lage ausklinkt. Zur sicheren Halterung kann das vordere Ende des Schraubendrehers 25 in eine dafür vorgesehene Haltenut 20 im Batterieauflagering 10 geschoben werden. (Fig. 4)FIG. 8 shows such a security lock, which can be opened with the aid of a screwdriver 25. To insert this screwdriver 25, a guide groove 23 is provided between the closure 9 of the battery drawer 4, 30 and the wall housing half 8 or the wall housing half 7, or both, through which the front end of the screwdriver 25 reaches the interior of the battery drawer 4 in the manner shown and by moving in the direction of the arrow disengages the drawer securing part pivoting about the recess 19 into the position shown in FIG. 6. For secure mounting, the front end of the screwdriver 25 can be pushed into a holding groove 20 provided in the battery support ring 10. (Fig. 4)

Auf diese Weise ist es möglich, die Kindersicherung, d.h. die Blockierung der Batterieschublade 4, durch den Eingriff der Sicherheitsverschlussausnehmung 11 um den Blockierzapfen 22 zu losen und die Batterieschublade 4 voll auszuschwenken.In this way, it is possible to release the child safety device, ie the blocking of the battery drawer 4, by the engagement of the safety lock recess 11 around the locking pin 22 and to pivot the battery drawer 4 fully out.

Währenddem die bisher beschriebene Batterieschublade 4 zylinderförmig, aber nicht nur beidseits, sondern auch auf einer Mantelseite offen ist, ist die in Fig. 9 dargestellte Ausführung, die Batterieschublade 30, ringförmig gechlossen. Diese Batterieschublade 30 weist anstelle der zylinderischen Bohrung 5 der Batterieschublade 4 beidseits eine Langlochvertiefung 37 und 38 auf, in welche im montierten Zustand je ein Achshalter 34 in die Gehäusehälfte 7 bzw. 35 in die Gehäusehälfte 8 vorsteht. Die beiden Achshalter 34 und 35 dienen der Halterung einer Lagerachse 31, welche ihrerseits zusätzlich in einem Schubladenlager 33 praktisch spielfrei gelagert ist.While the previously described battery drawer 4 is cylindrical, but not only open on both sides, but also on one side of the casing, the embodiment shown in FIG. 9, the battery drawer 30, is closed in a ring. This battery drawer 30 has instead of the cylindrical bore 5 of the battery drawer 4 on both sides an elongated hole recess 37 and 38, in each of which an axle holder 34 protrudes into the housing half 7 and 35 into the housing half 8 in the assembled state. The two axle holders 34 and 35 serve to hold a bearing axle 31, which in turn is additionally mounted practically free of play in a drawer bearing 33.

Die Batterieschublade 30 ist, wie Fig. 10 zeigt, beidseits der Schubladenlager 33 mit einer Bohrung 39 versehen.As shown in FIG. 10, the battery drawer 30 is provided with a bore 39 on both sides of the drawer bearing 33.

Diese Ausführung erlaubt das Ueberstreifen des Blockierzapfens 22 beim Drücken in Pfeilrichtung (Fig. 6) auch dann, wenn die Batterieschublade sich nicht elastisch verformen lässt oder wenn keine Biegestelle wirken kann (wie das in Fig. 9 gezeigt wird).This embodiment allows the locking pin 22 to be slipped on when pressed in the direction of the arrow (FIG. 6) even if the battery drawer cannot be elastically deformed or if no bending point can act (as is shown in FIG. 9).

Während die beiden erläuterten Ausführungsbeispiele sog. Kindersicherungen zeigen, bei welchen Teile elastisch deformiert oder durch Verschiebung ausser Eingriff mit Sicherungselementen gebracht werden, ist es natürlich auch möglich, die Batterieschubladen als feste Teile in das Gehäuse des Hörgerätes einzubauen und sie mit entsprechend gesicherten Deckeln abzudecken. Eine der einfachsten Möglichkeiten ist jedoch diejenige gemäss den Fig. 1 bis 8 der erläuterten Ausführung.While the two exemplary embodiments explained show so-called child locks, in which parts are deformed elastically or are disengaged from engagement with locking elements by displacement, it is of course also possible to install the battery drawers as solid parts in the housing of the hearing aid and to cover them with appropriately secured covers. However, one of the simplest options is that according to FIGS. 1 to 8 of the embodiment explained.

Es ist natürlich auch möglich, derartige Hörgeräte ohne Kindersicherung, jedoch mit deren Einbaumöglichkeit vorzusehen. Auf diese Weise kann dem Auftauchen von Kindern in der Familie an vorhandenen Hörgeräten die Kindersicherung jederzeit eingebaut werden.It is of course also possible to provide hearing aids of this type without childproof lock, but with their installation option. In this way, the appearance of children in the family on existing hearing aids, the child lock can be installed at any time.
