Abstract
A system for adjusting tension on fabric panels between two structural members of a fabric panel structure is disclosed. The system includes a rib that extends outwards from the structural members, a first keder rail located adjacent to the rib, a second keder rail located opposite to the rib of the first keder rail, and a fastener that passes through apertures in the first keder rail, the rib, and second keder rail to secure the keder rails against the rib. Preferably, the fastener is adjustable to allow the keder rails to be opened and closed to assist with installing or replacing fabric panels. Alternate embodiments can secure one of the keder rails directly to the structural member without the use of the rib.
Claims18
A system for adjusting tension on fabric panels between two structural members of a fabric panel structure, the system comprising:
- a rib extending outwardly from at least one of the structural members, the rib defining an aperture, the rib fixedly attached to the structural member;
- a first keder rail located adjacent to the rib, the first keder rail defining an aperture;
- a second keder rail located opposite to the rib of the first keder rail, the second keder rail defining an aperture;
- a fastener that passes through the aperture in the first keder rail, the aperture in the rib, and engages with the aperture in the second keder rail, the aperture of the second keder rail is threaded to engage the fastener, and the fastener secures the first and second keder rails against the rib;
- and
- wherein the first and second keder rails each have a keder channel for receiving the fabric panels, the aperture in the first keder rail and the aperture in the second keder rail are each positioned between the keder channel and a bottom portion of the corresponding first and second keder rail adjacent the structural member to provide clearance to allow the fastener to be adjusted from within the fabric panel structure.

- a fastener that passes through the aperture in the first keder rail;
- a second keder rail located adjacent to the first keder rail, the second keder rail defining an aperture that threadingly engages the fastener and secures the second keder rail to the first keder rail;
- and
- wherein the first and second keder rails each have a keder channel for receiving the fabric panels, the aperture in the first keder rail and the aperture in the second keder rail are each positioned between the keder channel and a bottom portion of the corresponding first and second keder rail adjacent the structural member to provide clearance to allow the fastener to be adjusted from within the fabric panel structure.
