Examination- or treatment chair and/or bed for use as mobile operating theater chair and/or -bed in e.g. dental medical practices, have lifting column comprising outer hollow section with recess that is formed in elongate-hole shape

摘要

#CMT# #/CMT# The chair and/or bed have a seat and/or a couch electromotively and/or hydraulically adjustable in its height by a lifting column (10). Rollers (27, 28, 28') are supported in pair wise at roller carriers (20, 20'), and plungers (31) are displaced against the column at the carriers. A recess (17) of an outer hollow section (11) of the column is formed in elongate-hole shape when a recess (18) of an inner hollow section (12) of the column corresponds to cross-section of the plungers, so that the carriers are pivoted by the plungers during lowering of an inner section. #CMT#USE : #/CMT# Examination- or treatment chair and/or bed for use as mobile operating theater (OP) chair and/or -bed in ear, nose and throat (ENT)- and dental medical practices and clinics. #CMT#ADVANTAGE : #/CMT# The arrangement of the rollers facilitates horizontal displacement of the chairs and/or beds. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a top perspective view of a foot portion of a lifting column for an examination- or treatment chair and/or bed. 10 : Lifting column 11 : Outer hollow section 12 : Inner hollow section 17, 18 : Recesses 20, 20' : Roller carriers 27, 28, 28' : Rollers 31 : Plungers.
