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 present invention relates to an hearing aid (1), which is provided with a housing (7), a battery compartment (6) and a locking mechanism of the battery compartment, wherein the locking mechanism includes a shaft (11) that mounted on the housing or the battery compartment, and a slide (8) with a borehole. The borehole and the shaft constitute conjunction, and that makes the slide movable on theshaft for the sake of locking and locking off the battery compartment inside the housing; wherein the borehole is provided with a circular intersecting surface, and the shaft is provided with a inter secting surface different from circular intersecting surface that has rotating symmetry while rotated at 360 DEG / n, wherein n is an integer larger than 1. the invention also relates to a battery compartment with this locking mechanism for hearing aid. intersecting surface of the shaft is different with borehole of the battery compartment, that makes the shaft can only connect with borehole of the battery compartment in several location. Thereby, on one hand, the slide can be fixed on the shaft enough firmly even if there is manufacturing tolerance, on the other hand, the slide can move on the shaft at smaller resistance force. In an optimized implement form, the shaft is designed as trilobal.

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...
