Abstract:
A sectional closing door comprising:a plurality of panels consecutively coupled together, each said panel having at least integral one profiled end form over at least a portion of a length thereof, in which two end forms define between consecutively coupled panels an open-ended swivel joints;at least one profiled matching part, said end forms when coupled being arranged to allow the reception and interlocking of said at least one profiled matching part constituting a rider made in one or more parts over the length of said coupled panels and forming a cover to close the open-ended swivel joint;said plurality of panels including a top panel, a bottom panel and a predetermined number of intermediately coupled panels therebetween said intermediately coupled panels each having a first end form and a second end form, said first end form including a partially spherical section defined by a pair of ends, wherein interior and exterior surfaces of said partially spherical section define a housing, each of said ends of said partially spherical section extending from a side edge of said panel, one of said ends of said panel while the other of said ends of said partially spherical section extends to an outside plane of the panel, said first end form further including a curved receiving slot for engagement with a curved connecting tab from a U-shaped, rider part;in which said second end form includes a curved interior section having a radius corresponding to a radius of the exterior surface of the partially spherical section of the first end form of an adjacently coupled panel, constituting a support and reference plane, said interior section being prolonged on the outside by an open ended spherical shaped protruding part having an opening and an arcuate slot, said arcuate slot being bordered on one side by said curved interior portion and on an opposite side by an exterior surface of said protruding part, said arcuate slot forming a housing for the protruding end of said first end form, wherein the open ends of said partially spherical section and said protruding part face the outside plane of said panels when consecutive panels are in axial alignment after said first and second end forms are coupled together;and in which said first and second end forms, when coupled, define an opening sized for receiving at least one profiled matching part or rider, said rider having a substantially U-shaped profile and including a pair of elastically deformable wings and an outside portion having a partially spherical profile, said outside portion interlocking in the opening defined in said coupled end forms to close the swivel joint, said rider further including an elongated curved tab which is designed to be received in mating engagement with said receiving slot in said first end form;and whereby when a panel is positioned at 90.degree. relative to an adjacent panel, joining is effective in that the part acting as a rider is connected to and integrated in one of the profiles of the end parts when one panel is swivelled to the maximum extent relative to another adjacent panel.
