ABSTRACT:
A sectional door, for buildings and the like, includes panel-like sections that are hingedly or pivotably connected to one another. The hinge joints that provide the pivotal connection have securing plates or brackets that extend around the pivot or hinge pin. In order to be able to effect a rapid and reliable securing of the hinge joints at any desired location along the edges of the sections, the edges of the sections that are to be connected are inventively provided with longitudinally extending slots for receiving the brackets. In addition, these edges are provided with longitudinally extending, groove-like recesses that proceed from the slots. Arresting members that cooperate with the brackets extend into the recesses. The recesses have a semicircular cross-sectional shape, and the arresting members have a spherical shape.
