Abstract: A device for orienting a platform, and a system having such a device, and a patient support having such a system. A support unit supports a load carried by the platform. Two actuators are arranged on mutually opposite sides of the support unit, and each of the actuators can be connected in articulated fashion to the platform at a respective support point. The actuators are configured to move the support points relative to the support unit independently of one another and to support the entire load carried by the platform on the support unit.

Abstract: An actuator includes at least one threaded spindle, at least one switch, at least one actuating element configured to actuate the switch, and at least one housing relative to which the threaded spindle is movable. The actuating element is attached to the housing. The housing may include at least one wall extending circumferentially around the threaded spindle and a first axial end wall and a second axial end wall, and the threaded spindle may pass through the first and second axial end walls. The first axial end wall may overlie the at least one switch, and a first end of the at least one actuating element may be connected to the housing and a second end of the at least one actuating element may extend between the at least one switch and the first axial end wall.

Abstract: An actuator includes a threaded spindle and an internally threaded component screwed onto the threaded spindle. The component includes a plastic element having a first axial end and a second axial end and an interior having a width and a radially inwardly projecting flange at the first axial end, and the flange has an inner diameter less than the width of the interior. A metal element, such as a nut, is fixedly mounted in the interior of the plastic element, and the internal thread of the nut has a maximum diameter greater than the inner diameter of the flange.

Abstract: An actuator includes a housing, a first nut in the housing, a second nut in the housing, and a threaded spindle screwed into the first nut and the second nut. The first nut exerts a first force in a first direction on the threaded spindle, and the second nut exerts a second force in a second direction on the threaded spindle, the first direction being different than the second direction.

Abstract: A transmission for an adjustable-height platform includes at least one drive shaft, at least one output shaft, at least one first gear wheel configured to transmit a rotational movement of the drive shaft to the output shaft, and at least one second gear wheel configured to drive a hollow second output shaft. The at least one first gear wheel is formed from or includes at least portions formed from plastic.

Abstract: The height of a platform relative to a support surface is adjustable by rotating a drive shaft to actuate a first height-adjusting device and a second height-adjusting device, thereby changing the height of the respective ends of the first and second height-adjusting devices relative to the support surface. The drive shaft is selectively drivable by either a drive motor or a manually-operable drive.
