DOOR PANEL

摘要

The invention relates to a flexible, bump-resistant door leaf, especially for overhead sliding doors, comprising a plurality of flexible panels (2) and, between any two of neighbouring panels (2), a flexible link element (4) extending along essentially the entire width of the door leaf. The link element comprises mating convex and concave sliding surfaces (36, 38) which engage with each other and together serve as a knee joint when mutually rotating the neighbouring panels (2). The concave sliding surface (38) encloses the convex sliding surface (36) through such a restricted angle that said link element (4) in itself permits an unimpeded vertical separation of the two neighbouring panels (2) but counteracts a mutual horizontal displacement of the panels. At each end of the link element (4) there is arranged an end coupling means (6) which prevents separation of the ends of neighbouring panels (2). Preferably, there is no panel-joining element in addition to the end coupling means (6).
