A lifting column includes at least five column elements which are at least partly nested, and a first and a second drive arrangement. The first drive arrangement is configured to move the three innermost column elements relative to one another. The second drive arrangement is configured to move the three outermost column elements relative to one another.

Nested lifting columns

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.

A mounting plate for mounting a lifting unit in a lifting column which lifting column includes at least two guide tube segments that are insertable substantially concentrically one-into-another and that are movable with respect to one another along their direction of extension in order to change the length of the lifting column. The mounting plate includes a motor-accommodating structure for a drive motor of the lifting unit and an accommodating structure, different from the motor-accommodating structure, for a support component of the lifting unit that is connectable in a rotationally fixed manner to mounting plate. The support component is disposed on a side of the lifting unit remote from or facing away from the drive motor. Also, a lifting column including the mounting plate.

Mounting plate and lifting column including a mounting plate

An electromechanical actuator includes a drive motor having rotatable drive shaft. A magnetic element is disposed on the drive shaft. A rotary-to-linear motion converter is driven by the rotatable drive shaft and includes a non-rotating actuator body that is linearly movable in a traveling direction. A Hall-effect sensor is disposed in a stationary manner proximal to the magnetic element disposed on the drive shaft. A controller is in electronic communication with the Hall-effect sensor. The controller counts the number of impulses output by the Hall-effect sensor when the drive shaft rotates relative to the Hall-effect sensor, and turns off the drive motor after a predetermined number of impulses have been counted since the start-up of the non-rotating actuator body. The controller may also count the number of times that the current of the drive motor exceeds a predetermined maximum value and store this counted value in a memory element.

Electromagnetic actuator

A device for providing an electrical or fluid junction includes a connecting structure such as a plate that it is connectable with an end of a columnar component having a hollow profile, and a junction structure such as a housing that is connected to the connecting structure and that includes at least one opening for providing an electrical or fluid junction for an external plug and a further opening for routing a line from the electrical junction into the columnar component.

Device for providing an electrical or fluid junction

Linear actuator device, comprising a housing (), an externally threaded screw (), a piston () and an internally threaded extended nut (), where the extended nut () comprises a plurality of longitudinal segments () having longitudinal edges () parallel to a center axis () of the internally threaded nut (), where each segment () has an identical radius of curvature and an angle of curvature of less than 360&#xb0;, so that the circumference of the internally threaded nut () is formed by at least two segments (). One advantage of the invention is that linear actuators of different lengths can be manufactured in an easy and cost-effective manner.
