Abstract: The invention is a device for pivoting a cover, particularly a glass cover, at a sales counter about a horizontally arranged pivoting axis. One or several profiles are provided on which the cover is supported in such a manner that it moves in a pivoting manner indirectly or directly by at least one articulation. At least one gas pressure spring is provided that comprises two ends articulated to the profile, the cover, the articulation, or to another structural component. The gas pressure spring supports at least the first part of the pivoting movement of the cover up to the dead point. At the dead point the center of gravity of the cover stands vertically above its pivoting axis. Both ends of the gas pressure spring are movably supported and during the further pivoting of the cover beyond the dead point, the force-supporting action of the gas pressure spring is off.

Abstract: A device for opening a panel on a sales counter which includes a basic structure. The panel is arranged on the front side of the sales counter. At least a first profile is provided, as is at least one second profile that is secured on the basic structure. The first profile, with the panel, is pivotable away from the basic structure by a control part. In a closed position, the panel closes the basic structure from the front side of the sales counter, and in an open position it is pivoted away from the basic structure. A control part has one end articulated on the first profile and another end articulated on the second profile or on the basic structure. The first profile is displaceably articulated at its one outer end on the second profile. The control part controls the rotary movement and sliding movement of the first profile.
