Definitions

  • the present invention relates to a height-adjustable support column for tables, treatment couches, beds and the like.
  • the invention has been especially developed in connection with the need for the raising and lowering of tabletops within a height range of 62-122 cm, reckoned from a floor surface.
  • a height adjustment range of this kind is requirement in an EU standard for computer tables. The height adjustment allows the table to be ergonomically adjusted to the individual user.
  • the lifting device is of large dimensions in order to also be able to take large side loads.
  • Another object of the invention is to provide a product in the form of a height-adjustable support column that is simple, inexpensive and reliable, and has a clean design.
  • Yet another object of the invention is to provide a height-adjustable support column where the actuator is a double-action actuator, i.e., that it has two directions of force (up and down), or can "run” either way. This prevents a jerky movement that easily occurs as a result of, for instance, an uneven distribution of turning moment and the ensuing uneven distribution of friction when using single-action actuators, where the force of gravity alone is typically responsible for the lowering movement.
  • the actuator is a double-action actuator, i.e., that it has two directions of force (up and down), or can "run” either way.
  • a particular object of the invention is to provide a height-adjustable support column having slide elements that are very readily adjustable and that act between pairs of telescoping tubes in a telescoping tubular column.
  • Adjustable slide elements are advantageous, in particular because they allow a reduction in the precision of the tubular sections of which the telescoping tubes are made.

  • first and second internal threaded portions are made on a respective sleeve body that is mounted in the respective hollow cylinder.
  • the cylindrical body can be designed for connection to a drive means, which may be a pulley in a pulley-and-cord drive or a direct-action electric motor.
  • a drive means which may be a pulley in a pulley-and-cord drive or a direct-action electric motor.
  • a height-adjustable support column comprising an actuator which acts between an underlying surface and a tabletop that is to be raised and lowered, and a sideways stabilised telescoping tubular column having a tube axis and constructed of intertele scoping tubes, and slide elements spaced apart around the circumference in the tubular column and which are mounted in one of the two respective, interacting telescoping tubes and have sliding contact with a slide face on the other of the two said tubes, wherein of a set of slide elements preferably arranged essentially in the same cross-sectional plane through the tubular column, one is adjustably mounted and is eccentrically arranged relative to the tube axis so that on an adjusting movement against the slide face there is obtained a rotational movement of the two tubes about a longitudinal axis in the tubular column, whereby the other slide elements in the unit are caused to tighten or slacken relative to their respective slide face.

  • the surrounding telescoping tubular column provides necessary sideways stabilisation, the individual telescoping tubes being mutually slide-supported by the said slide elements.
  • the number of adjustable slide elements in the same cross-sectional plane is reduced, preferably so that it is sufficient to have one adjustable slide element in a set of slide elements located in a cross-sectional plane.
  • the telescoping screw actuator may advantageously be a screw actuator that includes a first hollow cylinder having a first internal threaded portion; a second hollow cylinder having external threads in engagement with said internal threaded portion and having a second internal threaded portion; and a cylindrical body having external threads in engagement with said second internal threaded portion.
  • a screw actuator of this kind can be made in a simple manner and can easily be dimensioned so that it gives the desired, preferred lifting range of between 62 and 122 cm relative to a floor surface on which the screw actuator rests.
  • first and second threaded portions are formed on a respective sleeve body that is mounted in the respective hollow cylinder.

  • a separate drive means for example, a non-illustrated pulley in a pulley- and-cord drive, or an electric motor, directly or via a suitable transmission.
  • the design of the screw actuator 2 is such that the cylindrical body 11 does not need to screw its ways to the top before the intermediate hollow cylinder 8 begins to rotate. Both the cylindrical body 11 and the hollow cylinder 8 can go around simultaneously, controlled, inter alia, by the friction between the threads. Provided that both thread systems have the same thread pitch, the lifting speed will nevertheless be constant. Loss of thread pitch motion in one of the thread systems will be countered by gain in the other thread system, and it is thus unimportant for the function where rotation takes place. As will be appreciated, the screw actuator will be double-acting. Lowering takes place by changing the direction of rotation of the cylindrical body 11.
