Abstract (en)
[origin: US6073674A] PCT No. PCT/DE96/02509 Sec. 371 Date Jul. 17, 1998 Sec. 102(e) Date Jul. 17, 1998 PCT Filed Dec. 23, 1996 PCT Pub. No. WO97/23700 PCT Pub. Date Jul. 3, 1997A sectioial overhead door is disclosed with a door leaf comprising several consecutive hinging panels (10, 10', 10'') which are guided in the known way by rollers (11) in horizontal tracks and in tracks (12, 12', 12'') joined to them to form a bow and are provided with a balancing device (15) in the form of approximately horizontal helical tension springs. The latter are designed to be space-saving, in particular with low drop heights, underneath the horizontal track sections extending into the building, such that on each of the outer side regions (27) of the horizontal track sections (12, 14) facing away from one another one or more helical tension spring units (16) are arranged approximately parallel to one another and one below the other. At least some of the helical tension spring units (16) consist of at least two coaxial helical springs (17, 18), the turns of which are mutually opposing and intersecting.
