  • Publication number: 20220053942
    Abstract: A bed system and related method is disclosed, the bed system comprising a bed frame and a mattress assembly pivotably mounted on the bed frame for pivoting the mattress assembly about a pivot axis to form a pivot angle between the mattress assembly and a longitudinal axis of the bed frame, the mattress assembly comprising aback part, a seat part and a leg part, wherein aback normal of the back part and the pivot axis forms a back angle, a seat normal of the seat part and the pivot axis forms a seat angle, and a leg normal of the leg part and the pivot axis forms a leg angle, the bed system comprising a controller device, wherein the controller device is configured to: move the mattress assembly from a first position to a second position, wherein, in the second position, the pivot angle is a second pivot angle in a range from 30 degrees to 80 degrees, and wherein the leg angle is a second leg angle larger than 45 degrees.

  • Patent number: 9247806
    Abstract: Lifting column, preferably for height adjustable tables, said lifting column comprising at least two relative to each other telescopically arranged members (2a, 2b, 2c). At least one slider (11) is arranged between the two members (2a, 2b, 2c), said slider being secured to one of the members (2b). The problem is play between the members (2a, 2b, 2c), resulting in an unstable lifting column. For solution of this problem the member (2b) to which the slider (11) is secured, is furnished with a resilient section (17) outlined by a groove (16, 18) against which at least a part of the slider (11) rests. The resilient section (17) can push the slider (11) into firm engagement against the two members (2b, 2c), at which a stable lifting column which is free from play is achieved.

  • Patent number: 9144301
    Abstract: A lifting column preferably, for height adjustable tables, includes a guide (5) and a drive unit (9), the guide (5) including at least a first member (5a) and a second member (5b), the members (5a, 5b, 5c) being arranged mutually telescopically relative to each other. At the end of the first member (5a) from which the second member (5b) can be displaced sliders are arranged on an internal side thereof. At the end of the second member (5b) extending into the first member (5a) sliders are likewise arranged on the outside thereof. In a first plane the sliders have a first, a large, prestressing between the first member (5a) and the second member (5b), while the sliders in the second plane have a second, a small, prestressing between the first (5a) and second member (5b). Thus, a good dampening of vibrations of the table is achieved in case of exposure to horizontal forces.

  • Patent number: 7538284
    Abstract: An electrical operating panel, in particular for height-adjustable tables equipped with actuators or lifting columns driven by an electric motor. The panel has a first part (1) intended for fixed mounting of the panel and a second part (2) with operating keys (19) for activating electrical switches. The two parts are hinged together, and the hinge is formed with a rotary shaft (10) on the no part and a bearing with a cylindrical face (13) on the other part and formed with interengaging projections (16) and depressions (15) such that the second part may assume various angular positions relative to the first part, the force between projections and depressions bearing greater than the necessary operative pressure on the operating keys, but smaller than the force necessary to manually move the second part between the various angular positions. The panel is of simple structure and easy to mount and use. The users may easily set the keyboard part in the desired angular position.
