Patent number: 11183900Abstract: A telescopic tube for use in a linear drive to be applied in articles of furniture such as beds, chairs and the like has an outer tube accommodating an inner lift tube which is longitudinally displaceable within the outer tube by the linear drive and projects from the outer tube at a front end opposite to the linear drive. An end cover having a seal closes and seals the front end and prevents any media from entering the outer tube and the linear drive.Type: GrantFiled: November 14, 2017Date of Patent: November 23, 2021Assignee: DEWERTOKIN TECHNOLOGY GROUP CO., LTDInventors: Andreas Oberndörfer, Jürgen Martin

Publication number: 20190363602Abstract: A linear drive, in particular for greater loads, and in particular for the adjustment of beds, includes a worm shaft. By means of the worm shaft, an electric motor drives a transmission angle portion adapted for rotatably receiving a worm gear. The worm gear drives a spindle holder, which non-rotatably receives a spindle. To simplify fabrication, a drive end of the spindle has at least one notch. At least one spindle holding region of the spindle holder includes plastic. A clamping pin is fitted into the at least one notch between the spindle holder and the spindle.Type: ApplicationFiled: November 14, 2017Publication date: November 28, 2019Inventors: Andreas OBERNDÖRFER, Jürgen MARTIN

Patent number: 9732833Abstract: An electromotive linear drive in the form of a dual drive adjust movably mounted parts of reclining and seating furniture. Two threaded spindles (2, 3) driven by a worm gear and which are arranged one behind the other and flush with one another for displacing a lifting element. Bearings are provided at both ends of each threaded spindle (2, 3). The bearings are designed as roller bearings (4, 5) having an inner ring (6) and an outer ring (7). The aim of the invention is to design an electromotive dual drive in such a way that a short overall length is achieved and that the stability of the structure is increased. Said aim is achieved by arranging an abutment between both roller bearings (4, 5), which accommodate the spindle ends, on which the roller bearings are supported on from both sides.Type: GrantFiled: June 27, 2013Date of Patent: August 15, 2017Assignee: DewertOkin GmbHInventors: Andreas Oberndörfer, Jürgen Martin

Patent number: 9543804Abstract: An electric linear drive, in particular for adjusting moveably mounted parts of furniture used for sitting or lying down, includes a drive motor, a threaded spindle, a speed reduction gear arranged between the drive motor and the threaded spindle, a spindle nut placed on the threaded spindle, which can be selectively locked in the direction of rotation and, depending on the direction of rotation of the threaded spindle, moved in the axial direction of the threaded spindle. The linear drive has a lifting element for adjusting the moveable furniture parts, the lifting element being driven by axial movement of the spindle nut. Simple design, easy assembly and operation, and robust mounting of the driving parts are achieved.Type: GrantFiled: November 6, 2012Date of Patent: January 10, 2017Assignee: DewertOkin GmbHInventor: Andreas Oberndorfer

Patent number: 9404562Abstract: An electromotive linear drive with a housing that is equipped with a drive unit, the output member of which is designed as linearly movable spindle nut that is operatively connected to a connecting part for connecting to another component. The spindle nut is engaged with the connecting part in the normal operating state by a first coupling part and a second coupling part engaged with said first coupling part, and the driving connection can be decoupled by a movement of at least one coupling part in the longitudinal direction of the spindle.Type: GrantFiled: April 18, 2012Date of Patent: August 2, 2016Assignee: DEWERTOKIN GMBHInventor: Andreas Oberndörfer
