Construction of a housing, particularly for tachographs, and of a cover pivotally arranged on the housing

摘要

A housing for an instrument, particularly of the type for indicating and recording speed. A front cover includes a window through which the indicator is visable. The cover is hinged to the housing on a horizontal axis spaced from the housing base so that the bottom of the cover swings inwardly of the housing while the top of the cover swings downwardly revealing a recording apparatus on its inner surface.
