Abstract: An apparatus is proposed for supporting a device, the apparatus having at least one foot with an undercut. The apparatus has a depression for accepting the foot and an engaging mechanism with a projection. When the device is moved toward the apparatus, the undercut presses against the projection and thereby displaces the engaging mechanism. As soon as an upper edge of the undercut moves below a lower edge of the projection, the engaging mechanism moves back toward its starting position and thereby engages the undercut of the foot.

Abstract: An apparatus is proposed for supporting a device on an apparatus, preferably with the capability of vertical positioning. The apparatus is characterized by beveled areas opposite one another, preferably for resting the apparatus on support elements with different shapes, such as cylindrical support rods having different diameters, and an elongated and essentially rectangular area, which preferably extends from the beveled areas, for supporting the apparatus on elongated apparatus such as a board with an elongated edge.

Abstract: A housing holder for a medical monitor, which can be a cardiotocograph, includes a housing reception unit provided with several recesses. The monitor housing of the medical monitor has a plurality of protrusions provided on the back wall thereof, and arranged such that they are adapted to be inserted into the recesses of the housing reception unit. At least one of the protrusions has a stationary, downwardly directed projection for engagement with the side of the housing reception unit facing away from the monitor housing, the engagement being effected in the area of the respective recess. At least one additional protrusion is equipped with a spring-loaded snap member for engagement with the side of the housing reception unit facing away from the monitor housing, the engagement being effected in the area of another of the recesses.
