Definitions
- the invention is particularly characterized by the provision of a closing device located between the holder and the casing and movable in and out to limit the movement of the holder at most to the switching operation and at least to an opening which just about prevents the removal of the battery.
- This invention relates to an electrical hearing aid the Operating current of which is taken from a current source located in the casing of the hearing aid upon a holder movable to exchange the source.
- the operating current is switched on and off relatively to the hearing aid by a movement of the holder and closing or opening of contacts.
- a resilient element operable between the holder and the casing snaps in rest locations in the switched on and switched off positions of the holder.
- Such switches are used particularly in hearing aids which are very small and carried on the head, such as, for example, hearing aids carried behind the ears, hearing aids mounted in the ears and hearing aids combined with eyeglasses.
- the battery holders consist often of so-called swinging carriers or drawers, namely, holders, which are, for example, ringshaped and which are swingably or slidably mounted in the casing and into which can be mounted as current source a battery or an accumulator source.
- the holder is then introduced jointly with the source into the casing. When it is moved in contacts provided in the casing are brought in contact with the polar surfaces of the battery.
- the switch located in the casing is connected with the source and sound signals received by the microphone are amplified and transmitted through the hearing aid to the user of the device as sound strengthened in its intensity, clang, etc.
- the actuating member for opening the battery holder moves into a position which is spaced from the container, so that when the user moves it can easily remain hanging and be opened completely, with the result that the battery falls out and can get lost.
- the holding of a battery holder which is somewhat, perhaps half open is difficult, since the holding upon a spring carrying location which permits movement on both sides, makes possible only a limited stopping possibility. It is therefore easily possible that during the switching off of the device it will open completely and the battery will fall out. Present day batteries are usually so small that they can easily get lost. This difficulty is particularly. important since hearing aids are used by elderly persons for whom it is not easy to operate small switching elements.
- An object of the present invention is to improve existing hearing aids.
- the battery holder is made without the use of additional space as a proper exchanger and a safe switch by providing between the holder and the casing a closing device which is movable in and out and which limits the movement of the holder at most to the switching operation and at least to an opening which just about prevents the outgo of the battery.
- a closing device which is movable in and out and which limits the movement of the holder at most to the switching operation and at least to an opening which just about prevents the outgo of the battery.
- the lock can be again switched off, so that an exchange of the current source is possible every time.
- the advantage of the present invention consists in that the holder of the current source is made secure agasinst unintentional opening.
- the lock is constructed as a resiliently removable hook connection which snaps when the holder is closed.
- the opening movement is made free by pushing away the resilient hook.
- the two hooks form interengaging stops which limit the switching off movements after the release of the contacts before an opening of the holder can take place through which the source could fall out.
- the extensions which the hooks carry on their free ends should have a length corresponding to the switch path, namely, the path along which the holder must be moved to carry out the switching operation.
- FIG. 1 is a perspective view of a hearing aid for use behind the ear provided with the holding means for the current source of the present invention.
- FIG. 2 shows the device of FIG. 1 when the supporting hook with the sound channel and the upper cover are removed.
- FIG. 3 shows on an enlarged scale a battery holder provided with a battery when switched off.
- FIG. 4 is a partial view of the device of FIG. 3 in a switched on condition.
- FIG. 1 shows a hearing aid 1 for use behind the ear having a casing 2 and a sound regulator 3 extending out of the casing.
- the battery holder 4 having a grip lug 6 and a releasing key 5, is located at that end of the casing 2 which is opposite the carrying hook 7.
- the hook 7 has on the one hand, a channel for incoming sound (not shown) and a channel for sound delivery to which a flexible hose 8 is connected.
- the end of the hose is connected by a hook 9 to an elastic ear insert 10.
- FIG. 2 The known operation of the device is'clearly illustrated in FIG. 2.
- the hook 7 When the hook 7 is fitted the sound conduit extending through thehook and opening atits front side, is connected to the socket 1 l.
- the socket 11 is connected with a microphone 13 which transmils sound signals to the amplifier 14. From there the strengthened signals reach the hearing device 15 and are then transmitted through the conduit 16 and its ex-' tension in the hook 7 to the hose 8 and through the hook 9 and insert 10 into the ear of the person carrying I is the end ofthe lug 24 at the holder 4 and the hook 22 is the end portion of the extension piece 25 resiliently connected to the casing 2.
- the holder 4 When the holder 4 is completely closed, as shown in FIG. 4, it is held by a resilient pin 27 extending over its nose-shaped lug 26.
- the pin 27 is fixed at one end to the casing 2 and thus is bent when the lug 26 slides past I it. It then engages with its side surface a recess 28 of the lug 26 and holds firmly the holder 4.
- the contacts 18 and 19 engage the pole surfaces 29 and 30 of the battery 17.
- the contacts are connected by conduits in the known manner with the amplifier 14.
- the key 5 is pressed in the direction of the arrow 5' against the resilient force of the part25 with which it is connected.
- the hook 22 is brought into the position 22' shown in FIG. 3 by broken lines, so that it is moved out of the path of movement of the hook 23.
- the hook 23 is freed, so that the holder 14 can be swung about the axle 21 to such an extent that the battery 17 can move out sufficiently between the parts 31 and 32 of the casing 2, so as to be removed from the holder 4 and replaced by another one.
- the hook 22 is pressed back by the inwardly inclined front surface of the hook 23. Due to the resilient action of the extension 25 the hook connection will move back into the position shown in FIGS. 3 and 4 during further movement of the holder 4. Unintended opening of the holder 4 is prevented in this position.
- An electric hearing aid comprising a casing, a holder mounted in said casing and movable between a switching position and an open position, a source of electrical energy carried by said holder, contacts engaging said source in the switching position of said holder, means connected with said contacts for receiving and amplifying sounds, a locking device located between and connected with said holder and said casing for limiting the movement of said holder to one between said switching position and a position adjacent to said open position, but preventing the removal of said source, said locking device comprising a resilient hook, said holder being round and comprising a lug and a hook carried by said lug and directed inwardly relatively to the roundness of said holder, the lastmentioned hook being adapted to engage behind the first-mentioned hook during a closing movement of said holder, a resilient extension piece carried by said casing and carrying the first-mentioned hook, and a pressure key adapted to engage the first-mentioned hook to move it out of the path of movement of the second-mentione
- An electrical hearing aid according to claim 1 comprising lugs having ends carrying said books, the length of said lugs corresponding to the switching movement of said holder.
