Patent number: 6915585Abstract: A spirit level including first and second profile elements which can be displaced relative to one another in a telescopic manner and fixed relative to one another by means of a fixing element. In order to ensure that the first and second profile elements remain aligned with each other irrespective of their position, the first profile element is a hollow profile consisting of two sections which can be joined by means of the second profile element. The first section is joined to the second profile element and the second section can be moved along the remaining area of the second profile element. 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 in the direction of a profile wall of the second section of the first profile element.Type: GrantFiled: June 4, 2002Date of Patent: July 12, 2005Assignee: STABILA Messgerate Gustav Ullrich GmbHInventor: Peter Von Wedemeyer

Patent number: 6836973Abstract: A tool for household, commercial, and industrial use is disclosed. The tool would be a multi-sectional level that would comprise many individual sections that would be pivotally attached to one another, with each section having a cylinder and a volume of liquid in the cylinder. Each cylinder would also have an internal bubble for use in measuring flat surfaces. The level could also be placed in a slide-lock mechanism to force the level into a straight shape. Either one or two slide-lock mechanism could be used with the level.Type: GrantFiled: April 24, 2003Date of Patent: January 4, 2005Inventor: Thomas Eccles, Jr.

Patent number: 6796045Abstract: The present invention provides a level including an elongated level body defining an exterior workpiece contacting surface thereon. A hanger structure is movably connected to the level body so as to be capable of being moved between a retracted position and a deployed position. The hanger structure includes a contacting surface thereon that, when the hanger structure is in the deployed position, is disposed outwardly from the level body to be engageable with a support surface and thereby enable the level to be hung.Type: GrantFiled: June 27, 2002Date of Patent: September 28, 2004Assignee: The Stanley WorksInventor: Kristofor Milton Hallee
