摘要

#CMT# #/CMT# The treatment couch (1) comprises a lever mechanism (1.1) for vertical adjustment of the couch. A gear base (6) cooperates with a support lever (2), which is mounted on a side of a pivotable holding element (3). The transmission base and the support lever co-operates with a motor drive (4). A deflecting lever (5) is pivotally coupled with the support lever by a deflection bearing (5.2) and is rotatably supported by a base camp (6.5) at the gear base. A guide lever (7) is pivotally coupled to the support lever by a guide bearing (7.2). #CMT#USE : #/CMT# Treatment couch, particularly dental patient chair. #CMT#ADVANTAGE : #/CMT# The deflecting lever is pivotally coupled with the support lever by a deflection bearing and is rotatably supported by a base camp at the gear base, and hence ensures high lift of the couch with a compact structure, and enables the operational use with small deflection or extension movement with necessary stiffness. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a treatment couch. 1 : Treatment couch 1.1 : Lever mechanism 2 : Support lever 3 : Holding element 4 : Motor drive 5 : Deflecting lever 5.2 : Deflection bearing 6 : Gear base 6.5 : Base camp 7 : Guide lever 7.2 : Guide bearing.
