Problems solved by technology

[0005] But when the cross-section of the hole is smaller than the cross-section of the shaft, the locking mechanism is difficult to unlock even with special tools
If the described fit is designed to be too tight in this way, it can even lead to damage to the locking mechanism when trying to unlock

Embodiment Construction

[0026] figure 1 Shown is a hearing aid known from the prior art, comprising a mouthpiece 2, a volume control 3, a programming socket 4, a programming button 5 with an off function (Aus-Funktion), and a battery compartment 6 with a locking mechanism.

[0027] Figure 2 to Figure 4 represented by perspective figure 1 The lower end of the hearing aid 1 with the battery box 6 in it. Here's the perspective view with figure 1 rotated slightly to better see the Figure 2-Figure 4 The opening and closing of the battery compartment 6 indicated in .

[0028] figure 2 It shows that the battery box 6 is opened from the housing 7 of the hearing aid 1 by turning. The battery box 6 is connected with the casing 7 through a rotary shaft on one side, and the locking mechanism is on the other side, and only the slide block 8 of the locking mechanism can be seen here.

[0029] image 3 Indicates that the battery box 6 is in an open state, and the battery 9 is being put into the battery b...

Abstract

The invention relates to a hearing aid (1), which has a casing (7), a battery box (6) and a locking mechanism for the battery box. The locking mechanism includes a shaft (11) mounted on the casing or the battery box and a The slider (8), the hole and the shaft form a fit, so that the slider can move on the shaft to lock and unlock the battery case in the casing, the hole has a circular cross section, and the shaft has a A cross-section other than circular having rotational symmetry when rotated 360° / n, n being an integer greater than 1. The invention also relates to a battery case for a hearing aid with such a locking mechanism. The cross-section of the passing shaft is different from the cross-section of the hole in the battery box, so that the shaft can only be connected with the hole in the battery box at a few places. This ensures, on the one hand, that the slider is fastened sufficiently securely on the shaft even in the event of manufacturing tolerances, and on the other hand, allows the slider to be moved on the shaft with little resistance. According to a preferred embodiment, the shaft is of trilobal design.

Description

technical field [0001] The invention relates to a hearing aid; such a hearing aid is known by the Siemens INIFINITY hearing aid. Furthermore, the invention relates to a battery compartment with a locking mechanism for a hearing aid; such a battery compartment is known from the same device described above. Background technique [0002] Traditional electric hearing aids have a housing with a battery compartment that houses the batteries. In order to avoid inadvertently opening the battery compartment and thereby dropping the battery, the battery compartment is locked inside the housing with a locking mechanism. Such locking mechanisms are often equipped with child safety devices, so that the locking mechanism can only be opened with special tools, such as small screwdrivers or pointed objects. [0003] The known locking mechanism has a slide block with a hole, the hole forms a fit with the shaft, and the slide block is movably mounted on the shaft, so that the battery case i...
