ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to an attachment device for a housing, having a snap-action device for snapping onto a hat rail, and having screw eyelets, which are formed integrally on the housing base, for attachment to a plate.
BACKGROUND INFORMATION
An attachment device is described in German Patent No. DE 31 49 310. This reference describes the attachment of electrical installation appliances on profiled hat rails, for which purpose slides are provided which are guided in the housing of the installation appliance and are pressed resiliently inward are provided. The inwardly facing ends of these slides are each provided with a lug which engages behind the profiled hat rail. The hat rail is arranged in a free standing position, so that even relatively high appliances can be attached to the hat rail.
German Patent No. DE 91 10 337 U1 describes an attachment device having a snap-action device for snapping onto a hat rail. Screw eyelets for attachment to a plate are provided on a housing base. On the underside of the housing base, the snap-action device has a latching lug with a beveled area which attaches to the hat rail.
SUMMARY
An object of the present invention is to provide an attachment device which allows an attachment device on high housings to be snapped onto a hat rail which is mounted on a plate and, at the same time, also allows screw attachment of the housing.
According to the present invention, this object is achieved by the fact that the underside of the housing base has a bevelled area at least on one side of the snap-action device, and that the screw eyelets, in this area, are each integrated in a spacer which is arranged resiliently on the housing base and when screwed together is supported on the plate.
