  • the further return pulley 9 is arranged opposite the one return pulley 8.
  • the flexible driving member 7 extends around and is tensioned between both the return pulley 8 and the further return pulley 9.
  • the return pulley 8 and the further return pulley 9 are mounted with a pulley mounting member 24 which spaces the return pulley 8 and the further return pulley 9 and aids in prestressing the flexible driving member 7.
  • the pulley mounting member 24 is coupled with one of its ends with the central profile part 3.
  • the pulley mounting member 24 is coupled with the central profile part 3 at one end of the central profile part 3 which one end faces the gear rack 10 that is in this case facing the first profile part 2.
  • both the motor unit 5 and the coupling system are coupled with the central profile part 3 at one end of the central profile part 3 which one end faces the gear rack 10.
  • the flexible driving member 7 is endless. I will be apparent that the flexible driving member 7 can be made “endless” by coupling both ends through a coupling piece 15 with the first profile part 2, as an example.

  • the motor unit 5 comprises a worm gear 12.
  • the worm gear 12 may directly drive a drive gear 16 or as an alternative drive the drive gear 16 indirect through a transmission.
  • the gear rack 10 is freestanding. This means that, when the telescopic support device 1 is in retracted position, the central profile part 3 extends between the first profile part 2 and the gear rack 10.
  • the gear rack 10 extends from the first profile part 2 towards the central profile part 3.
  • One end of the gear rack 10 is mounted with the first profile part 2.
  • the one end of the gear rack 10 is mounted with the first profile part 2 through mounting means 21.
