System for fixing objects to rails has shaft passing rotatably through bore in plate element with contour that interacts with radial shaft protrusion to hold shaft under tension with adapter clamped

摘要

The system has a slotted rail with a channel and an adapter with a bolt for insertion into the channel in one orientation pivotable to lock the adapter to the rail in a second orientation, a shaft joined to the bolt and a plate-shaped element in contact with the slotted exterior of the rail. The shaft passes rotatably through the plate-shaped element whose surface contour interacts with a radial shaft protrusion to hold the shaft under tension. The attachment system has a slotted rail bounding an undercut channel and an adapter for mounting on the rail with a bolt (11) for insertion into the channel in a first orientation and pivotable to lock the adapter to the rail in a second orientation, a shaft (5) joined to the bolt and a plate-shaped element (10) with a bore (21) in contact with the slotted exterior of the rail. The shaft passes rotatably through the bore and the plate-shaped element has a surface contour on its side remote from the rail that interacts with a radial protrusion (9) on the shaft to hold the shaft under tension with the adapter clamped.
