Rise and fall telescopic furniture adjustment actuator for home, office and medical applications, combines coaxial guidance with symmetrical transmission train

摘要

The telescopic profile (13) is guided through the standing profile (12) with little play. The motor (1) drives the unit through a central coaxial drive shaft (20) in the telescopic profile. Two guide rods (10,10a), symmetrical about the drive shaft, project freely into the telescopic profile. Torque from the drive shaft is transmitted to wheels (6a,9) engaging the drive rods, through a symmetrical transmission system (3-8,3a-8a).
