Patent ID: 6915585

Claim:
Spirit level ( 10 ) comprising a first and a second profile element ( 12 , 28 ), which can be displaced relative to one another in a telescopic manner and can be fixed relative to one another by means of a fixing element ( 56 ), wherein the first profile element ( 12 ) is a hollow profile element, characterized in that the first profile element ( 12 ) is divided into a first and a second longitudinal chamber ( 16 , 18 ), in that the first profile element is comprised of a first and a second section ( 22 , 24 ), which are joined to one another via the second profile element ( 28 ), in that the second profile element is firmly joined to the first section and the second section can be displaced along the second profile element, in that a clamping element ( 54 ) is part of the fixing element ( 56 ) and extends from the first longitudinal chamber and extends into a second longitudinal camber of the first profile element, wherein, when the second profile element is at least partially uncovered by the second section, the second profile element can be subjected to the action of force by means of the clamping element in the direction of a profile wall ( 36 ) of the second section of the first profile element, and the second profile element can be fixed to the second section of the first profile element.
