Cover device for hearing aids
View Patent ↗For reducing the space requirement for locking systems, a battery compartment and an electronics module are locked by means of a single articulation. For removing the battery, the battery compartment is swiveled open; for unlocking the electronics module, the battery compartment is removed from the plate by pulling the wire spring from the receptacles. The articulation thus has a double function.
1. A device for covering a hearing aid housing, comprising:
a housing cover that comprises an opening for introducing a battery;
an electronics module which is equipped with an amplifier and a microphone; and
a battery compartment that is pivotably attached directly to the housing cover with a connector element, the battery compartment being configured to accept a battery and being configured to cover the opening such that in every pivoted condition, the electronics module cannot be moved through the opening, the pivoting element with the battery compartment being removable from the housing cover so that the electronics module can be moved through the opening when the battery compartment is removed from the housing cover.
2. The device according to claim 1 , wherein the pivoting element comprises a wire spring having two end sections and an elastic middle section lying between the two end sections.
3. The device according to claim 2 , wherein the end sections of the wire spring lie on an axis in a loaded condition, and the middle section comprises a shape selected from the group consisting of circular arc-shaped, U-shaped or triangular-shaped.
4. The device according to claim 2 , wherein the battery compartment comprises guides through which the end sections of the wire spring project into receptacles of the housing cover.
5. The device according to claim 4 , wherein the middle section of the wire spring is configured to be bent such that the end sections of the wire spring can be pulled completely from the receptacles of the housing cover in order to remove the battery compartment from the housing cover.
6. The device according to claim 1 , wherein the opening in the housing cover comprises at least one guide channel for guiding the electronics module when it is conducted through the opening.
7. The device according to claim 1 , wherein the battery compartment is configured to be pivoted into a closed condition in which it completely covers the opening.
8. The device according to claim 1 , wherein the battery compartment comprises a sound opening for a microphone integrated in the electronics module.
