This prevents the current-consuming hearing aid components from making contact with the battery when the battery receptacle is opened into the "off" position. …<IMAGE>…

Description

Die Erfindung betrifft ein Hörgerät mit einer in einem Batterie­fach des Gehäuses angeordneten Batterie, einer Kontaktfederan­ordnung zur elektrischen Verbindung der Batterie mit Hörgeräte­bauteilen, die mit Strom zu versorgen sind, wobei die in eine aufklappbare Batterielade eingelegte Batterie mit dem einen Batteriepol an einem ersten Kontakt der Kontaktfederanordnung anliegt und bei geschlossener Batterielade und eingeschaltetem Hörgerät der Stromkreis über eine Kontaktfeder zu den zu ver­sorgenden Hörgerätebauteilen schließbar ist.The invention relates to a hearing aid with a battery arranged in a battery compartment of the housing, a contact spring arrangement for the electrical connection of the battery to hearing aid components which are to be supplied with current, the battery inserted in a hinged battery drawer having the one battery pole at a first contact of the contact spring arrangement is present and the circuit can be closed via a contact spring to the hearing aid components to be supplied when the battery charger is closed and the hearing aid is switched on.

Das Ein- und Ausschalten bekannter Hörgeräte (z.B. DE-AS 25 03 253) erfolgt häufig wegen Raumbedarf nicht durch einen zusätzlich angeorndeten Schalter, sondern durch eine schwenk­bare Batterielade. Die zwei üblichen Kontakte sind derart in bezug auf die Batterielade im Hörgerät eingebaut, daß beide nur dann die Batterie berühren, wenn diese völlig in das Hörgeräte­gehäuse eingeschwenkt ist. In dieser ersten Stellung ("Ein"-­Stellung) ist das Hörgerät eingeschaltet, d.h. Hörgerätbauteile, die mit Strom versorgt werden müssen (einschließlich des Hörge­rätverstärkerteils), liegen an Spannung. Die schwenkbare Bat­terielade weist jedoch noch zwei zusätzliche Schwenkstellungen auf. In einer zweiten, etwas ausgeschwenkten Stellung ("Aus"-­Stellung) soll die Batterie nur eine Kontaktfeder berühren, kann aber nicht entfernt werden oder herausfallen, da die Bat­terielade nur teilweise aus dem Gehäuse ragt. Diese Stellung entspricht an sich dem völlig ausgeschalteten Zustand des Hör­gerätes, da alle mit Strom zu versorgenden Hörgerätbauteile von der Batterie abgeschaltet sein sollen. Bei einer ungünstigen Kipplage der Batterie kann es dennoch zu einer unerwünschten Kontaktlage zwischen der Batterie und den beiden Polkontakten kommen. In einer dritten Stellung ("Batteriewechsel"-Stellung) ist die Lade ganz aus dem Hörgerätgehäuse herauszuschwenken. Die Batterie kann in dieser Stellung herausgenommen werden.Known hearing aids (for example DE-AS 25 03 253) are often switched on and off not by an additional switch, but by a swiveling battery charger, due to space requirements. The two usual contacts are installed in relation to the battery drawer in the hearing aid that both only touch the battery when it is fully pivoted into the hearing aid housing. In this first position ("on" position) the hearing aid is switched on, ie hearing aid components that have to be supplied with power (including the hearing aid amplifier part) are live. However, the swiveling battery drawer has two additional swivel positions. In a second, somewhat swung-out position ("off" position), the battery should only touch a contact spring, but cannot be removed or fall out since the battery drawer only partially protrudes from the housing. This position corresponds to the completely switched-off state of the hearing aid, since all hearing aid components to be supplied with current should be switched off by the battery. In the event of an unfavorable tilting position of the battery, an undesirable contact position between the battery and the two pole contacts can nevertheless occur come. In a third position ("battery change" position), the drawer can be swiveled completely out of the hearing aid housing. The battery can be removed in this position.

Aufgabe vorliegender Erfindung ist es, ein Hörgerät der ein­gangs beschriebenen Art so auszubilden, daß die Kontaktfeder­anordnung in einfacher Weise ausgebildet und leicht montierbar ist, wobei zugleich eine Justierung erreicht wird, die verhin­dert, daß ein Kontaktanschluß der stromverbrauchenden Hörge­rätebauteile mit der Batterie erfolgen kann, wenn die Batterie­lade in die "Aus"-Stellung oder in die "Batteriewechsel"-Stel­lung geöffnet ist.The object of the present invention is to design a hearing aid of the type described at the outset in such a way that the contact spring arrangement is designed in a simple manner and is easy to assemble, at the same time achieving an adjustment which prevents the power-consuming hearing aid components from being able to be connected to the battery if the battery drawer is open in the "off" position or in the "battery change" position.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Schutzanspruches 1 gelöst. Vorteilhafte Ausge­staltungen der Erfindung sind in den Schutzansprüchen 2 und 3 gekennzeichnet.This object is achieved by the characterizing features of claim 1. Advantageous embodiments of the invention are characterized in the claims 2 and 3.

Durch den Einsatz der Kontaktfeder und ihre einfache Befesti­gung ist die Anordnung dieses Kontaktfederteils ohne zusätz­liches Justieren bei der vor- und/oder Endmontage des Hörge­rätes möglich. Nach der Erfindung wird ein Befestigungsele­ment, z.B. eine Kunststoff-Spange, in das Hörgerätegehäuse eingesetzt, derart, daß dieses Element die eine Kontaktfeder der Kontaktfederanordnung mit Vorspannung in einer Lage hält, die einer justierten Lage entspricht. Dieses Element bzw. die­se Spange weist desweiteren einen isolierten Federarm auf, der in der etwas ausgeschwenkten Stellung der Batterielade ("Aus"-­Stellung) verhindert, daß der zweite Batteriepol mit der Kon­taktfeder in Berührung kommt, da gegenüber dem mit der Batterie ausgerückten isolierten Federarm die Kontaktfeder der Kontakt­federanordnung in dieser Bewegung durch einen Anschlag der Spange begrenzt ist und nicht nachrücken kann.Through the use of the contact spring and its simple attachment, the arrangement of this contact spring part is possible without additional adjustment during the pre- and / or final assembly of the hearing aid. According to the invention, a fastening element, for example a plastic clasp, is inserted into the hearing aid housing in such a way that this element holds the one contact spring of the contact spring arrangement with pretension in a position which corresponds to an adjusted position. This element or this clasp furthermore has an insulated spring arm which, in the somewhat swiveled-out position of the battery drawer ("off" position), prevents the second battery pole from coming into contact with the contact spring, as compared to the insulated spring arm disengaged from the battery the contact spring of the contact spring arrangement is limited in this movement by a stop of the clasp and cannot move up.

Weitere Vorteile und Einzelheiten der Erfindung ergeben sich aus der Beschreibung eines Ausführungsbeispieles anhand der Zeichnung.Further advantages and details of the invention result from the description of an exemplary embodiment with reference to the drawing.

Es zeigen:

Show it:
  • 1 shows a schematically and enlarged distal end of a behind-the-ear hearing device with a closed battery charger, the contact spring arrangement between the battery and the hearing device components to be supplied with current being closed,
  • FIG. 2 shows the enlarged distal end of the hearing aid shown in FIG. 1, with the battery drawer slightly unfolded into the “off” position,
  • FIG. 3 shows a structural design of the contact spring arrangement according to the invention in side view,
  • Figure 4 is a plan view of Figure 3, with no support element is associated with the spring arm.

Die Figuren zeigen ein hinter dem Ohr zu tragendes Hörgerät, dessen Gehäuse 2, in dem die Hörgerätebauteile, wie z.B. Mikro­fon, Verstärker 13, Hörer, Batterie 3 usw. angeordnet sind, vorzugsweise schalenförmig ausgebildet wird. Am distalen Ende des Hörgerätes weist das Gehäuse ein Batteriefach 1 und eine schwenkbare Klappe als Batterielade 8 auf. Zur Bedienung der Batterielade ist außenseitig eine Handhabe 18 angeformt. Für die Arretierung der Batterielade am Gehäuse 2 in der Verschluß­lage oder "Ein"-Stellung und in einer zweiten, etwas ausge­schwenkten Stellung ("Aus"-Stellung) ist ein Rastnasen/Rast­mulden-Mechanismus 19, 20, 21 od.dgl. vorgesehen.The figures show a hearing aid to be worn behind the ear, its housing 2, in which the hearing aid components, e.g. Microphone, amplifier 13, handset, battery 3, etc. are arranged, preferably a bowl-shaped. At the distal end of the hearing aid, the housing has a battery compartment 1 and a pivotable flap as a battery drawer 8. To operate the battery drawer, a handle 18 is molded on the outside. For locking the battery drawer on the housing 2 in the closed position or "on" position and in a second, somewhat pivoted-out position ("off" position), a catch / recessed mechanism 19, 20, 21 or the like is. intended.

In der geschlossenen, verrasteten Stellung der Batterielade 8 sitzt die Batterie 3 fest in einer Ausnehmung der Batterielade, wobei der den Pluspol 9 bildende Batteriemantel in leitender Verbindung mit einem ersten Kontakt 4 steht. Die den Minuspol 15 bildende große Batteriefläche kontaktiert eine Kontaktfeder 10 und außerdem stützt sich auf dieser Batteriefläche ein iso­lierender Federarm 16 gegen die Batterie ab. Dieser Federarm 16 ist vorzugsweise Teil eines Elementes 14, beispielsweise einer Spange, die am Gehäuse 2 bzw. an einem Lagerbock 22 des Gehäu­ses z.B. durch Schrauben 23 befestigbar ist und die Kontakt­feder 10 in einer vorgegebenen Lage hält und zugleich die Kon­taktfeder 10 unter Vorspannung dadurch justiert. Zwecks ein­facher Montage steckt das batterieabgewandte freie Ende der Kontaktfeder 10 in einer Leiterplatte eines Verstärkers 13, so daß in der beschriebenen Kontaktfederanordnung die Hörge­rätebauteile 5, 6, 7 an einem geschlossenen Stromkreis liegen, in dem auch noch ein zusätzlicher Ein-Aus-Schalter angeorndet sein kann.In the closed, latched position of the battery drawer 8, the battery 3 is firmly seated in a recess in the battery drawer, the battery jacket forming the positive pole 9 being conductive Connection to a first contact 4 is established. The large battery area forming the negative pole 15 contacts a contact spring 10 and an insulating spring arm 16 is also supported on this battery area against the battery. This spring arm 16 is preferably part of an element 14, for example a clip, which can be fastened to the housing 2 or to a bearing block 22 of the housing, for example by means of screws 23, and which holds the contact spring 10 in a predetermined position and at the same time adjusts the contact spring 10 under pretension . For the purpose of simple assembly, the free end of the contact spring 10 facing away from the battery is inserted in a circuit board of an amplifier 13, so that in the described contact spring arrangement the hearing device components 5, 6, 7 are connected to a closed circuit in which an additional on-off switch is also arranged can.

In einfacher Montage wird die Kontaktfeder 10 in eine Aufnahme der Leiterplatte 12 des Verstärkers 13 eingesetzt. Daraufhin wird der Verstärker mit der Kontaktfeder in das Hörgerätegehäu­se eingesetzt und das schalenförmige Gehäuse geschlossen. Bei geöffnetem Gehäuse oder geöffneter Batterielade wird die Spange 14 eingesetzt und gegen angespritzte Lagerbuchsen des Gehäuses bzw. Lagerbocks 22 befestigt, z.B. geschraubt oder gesteckt. Dabei wird die Kontaktfeder 10 von einer vorgespannten Lage in die zugeordnete Justierlage gebracht. Wird die Batterie in die Batterielade eingelegt, die Batterielade geschlossen und gege­benenfalls ein zusätzlicher Schalter geschlossen, so liegt die Batterie kontaktiert an den ihren Polen zugeordneten Kontakten an und das Hörgerät ist eingeschaltet.In a simple assembly, the contact spring 10 is inserted into a receptacle in the printed circuit board 12 of the amplifier 13. The amplifier with the contact spring is then inserted into the hearing aid housing and the shell-shaped housing is closed. With the housing open or the battery door open, the clip 14 is inserted and fastened against molded bearing bushes of the housing or bearing block 22, e.g. screwed or inserted. The contact spring 10 is brought from a prestressed position into the assigned adjustment position. If the battery is inserted into the battery drawer, the battery drawer is closed and, if necessary, an additional switch is closed, the battery contacts the contacts assigned to its poles and the hearing aid is switched on.

Bei ausgeschaltetem Hörgerät (teilweise oder völlig geöffneter Batterielade) hebt die Batterie mit Abstand von der Kontaktfe­der ab und der gegen die Batterie drückende, isolierte Feder­arm der Spange verhindert, daß die Batterie auf den Kontakt der Kontaktfeder fallen kann. Da der isolierte Arm der Spange bei geöffneter Batterielade den Kontakt der Kontaktfeder überragt, ist in der "Aus"-Stellung des Hörgerätes eine Kontaktlage der Batterie an der Kontaktfeder ausgeschlossen. Wird daraufhin die Batterielade wieder geschlossen, so kommt die Batterie in Kon­takt mit der Kontaktfeder und der isolierte, zurückbewegte Arm der Spange bleibt in Anlage an der Batterie. Als Verstärkung der Kraft des Federarmes 16 der Spange 14 kann der Federarm 16 durch ein Stützelement 17 federnd abgestützt sein.When the hearing aid is switched off (the battery drawer is partially or fully open), the battery lifts away from the contact spring and the insulated spring arm of the clip, which presses against the battery, prevents the battery from falling onto the contact of the contact spring. Because the isolated arm of the clasp opened battery drawer protrudes the contact of the contact spring, a contact position of the battery on the contact spring is excluded in the "off" position of the hearing aid. If the battery door is then closed again, the battery comes into contact with the contact spring and the insulated, moved-back arm of the clip remains in contact with the battery. To increase the force of the spring arm 16 of the clasp 14, the spring arm 16 can be resiliently supported by a support element 17.
