Snap-on fastening device for hearing device

This application claims priority of German application No. 10 2007 010 011.8 filed Mar. 1, 2007, which is incorporated by reference herein in its entirety.

The invention relates to a snap-on fastening device of a hearing device.

With housing elements (shells) of a hearing device which are fastened to a frame for accommodating internal components of the hearing device, the use of large numbers of additional parts is problematic because of the risk of losing parts.

Housing fastenings on the frame by a number of snap-on connections cannot be used for reasons of size dimensioning.

The complex frame must be fixed in the hearing device housing and also be able to be easily and quickly released when the housing (shell) is changed.

Previously the frame has been supported directly in one housing shell with the shells then being screwed together. Another solution is to use pins which are pushed through the frame and the housing.

With housing elements of a hearing device which are fastened to a frame for accommodating internal components of the hearing device, the use of a large number of additional parts is problematic because of the risk of losing parts. The object of the invention is therefore to provide a snap-on fastening means that is used to fasten a housing element to the frame of the hearing device, with an opening being provided in the housing element and the frame for accommodating the snap-on fastening means.

The invention is also shown in the form of a drawing comprising three figures.

FIG. 1 shows a cross-sectional diagram of the hearing device without the electrical components, i.e. a housing element GH, a frame FR and a snap-on fastening element SF in the snapped-on state.

FIG. 2 shows a cross-sectional diagram of the hearing device in detail, with the snap-on fastening SF in the snapped-on state.

FIG. 3 shows a cross-sectional diagram of the hearing device in detail, with the snap-on fastening element SF shown removed from the snap-on opening.

In accordance with the invention a snap-on fastening means for fastening a housing element (shell) to the frame of the hearing device is used, with an opening being provided in the housing element and the frame for accommodating the snap-on fastening means, and with the snap-on spring of the snap-on fastening means being embodied so as to reach through the opening of the housing element and of the frame and to snap onto the frame, which simultaneously fixes the frame.

The advantage of the invention is that no pins or screws which disturb the design are used on the housing and that no size problems arise.

In a variant of the invention the snap-on fastening means is simultaneously employed as the type designation plate. That part of the snap-on fastening means SF which is used as the type designation plate locates in the opening in the housing. The result of this is to integrate the type designation plate in the snap-on fastening means.

In a further variant or embodiment of the invention two housing shells can be used which are fitted onto one side (e.g. upper side) of the frame and on the other side (e.g. lower side) are held together by the snap-on fastening means, with the frame being fixed at the same time by the snap-on fastening means.
