Definitions

  • the present disclosure relates to a hearing aid supplied by power from a battery and comprising an opening and closing mechanism allowing the battery to be provided with power when in use and turned off when needed. More particularly, the disclosure relates to a hearing aid provided with a battery drawer configured to receive a battery, wherein the opening and closing mechanism is configured as part of a detachable arm member.
  • a hearing aid comprising a housing and a battery drawer configured to be connected to the housing wherein the battery drawer comprises a detachable arm member is disclosed.
  • the battery drawer comprises a joint structure configured to be attached to a part of the housing and allowing rotation of the battery drawer in relation to the housing.
  • the battery drawer comprises a compartment shaped and configured to receive a battery
  • the battery drawer comprises a detachably attached arm member, which arm member comprises one or more engagement structures configured to engage with a locking structure of the housing, and wherein at least a first of the one or more engagement structures engages with the locking structure of the housing in a first fully closed position, and at least a second of said one or more engagement structures engages with the locking structure of the housing in a second open position of the battery drawer.
  • a detachable arm member configured to be arranged in a part of the battery drawer and comprising the one or more engagement structures engaging with a part of the housing in a closed position of the battery drawer, it is possible to replace the arm member when the engagement structures have been exposed to wear and degradation. In this way, the construction of a detachable arm member minimizes the need for changing the entire battery drawer, but merely the "closing and opening mechanism" integrated into the arm member needs to be changed.
  • the arm member in another (e.g. more wear resistant) material than the remaining battery drawer.

  • the battery drawer is configured to be connected to the housing. This may be accomplished by any suitable means of connection, including mechanical attachment structures.
  • the battery drawer may be attached directly to one or more structures of the housing. Alternatively, the battery drawer may be attached to one or more intermediate structures that are attached to the housing.
  • a joint structure is suitable for attaching the battery drawer rotatably to the housing.
  • the battery drawer can be opened and closed in an easy and user-friendly manner. This is important, since the battery drawer needs to be opened and closed to insert and remove a battery and in order to turn on the hearing aid, which "on" position is achieved when at least a first of the one or more engagement structures of the battery drawer is engaging with a locking structure of the housing An “off” position is achieved by rotating the battery drawer away from the housing, whereby a second engagement structure engages with the locking structure allowing a first open position of the battery drawer. It should be noted that this open and closing of the battery drawer will cause the engagement structure to be worn over time, why the need for an exchangeable arm member having these engagement structures integrated therein is present.
  • the battery drawer is constructed such that the arm member may be guided into a portion of the battery drawer.
  • the battery drawer comprises a track structure
  • the arm member comprises a corresponding slide structure configured to be arranged in the track structure, wherein the slide structure is configured to be inserted into the track structure in a removable manner.

  • the two upper portions form a narrow opening, also construed as a gap.
  • the upper portions constitute a locking structure of the track structure.
  • the track has a bottom portion having a base, configured to abut and hereby guide a corresponding base of the arm member.
