TITLE:  Locking mechanism for Battery door

ABSTRACT

The invention describes a novel battery door design for batteries used in hearing aids.  The design incorporates a locking mechanism with the battery contact, thus facilitating a tamper-resistant lock on the battery door.

BACKGROUND/DEFINITION OF PROBLEM

The batteries used in many hearing aid devices are vulnerable to tampering or unwanted opening because the battery doors do not have an adequate locking mechanism.

DETAILED DESCRIPTION

The invention is a tamper-resistant locking mechanism for hearing aid batteries.  The novel contribution is the concept of using a locking mechanism with the battery contact such that it blocks the movement of the battery connector.  By adding a blocking device to the design, the battery contact is unable to move. The battery door is then unable to open.

The example in this detailed description uses the positive battery connector for a PR44 battery (Zink-Air battery) for locking the battery door.  The example also uses a type of battery door recognized as “swing out”; however, the concept is applicable to a variety of battery doors and types of batteries.

Components

The Rotation axis and battery connector are fixated in the device housing (not shown in the figure).  (Figure 1)
