摘要:
A fastener bead removably affixed to a flexible tension element of a cargo holder and used by removably inserting the bead in the wider portion of a keyhole-type slot in a support structure. The bead in use is trapped and held by the margin of the narrow portion of the keyhole slot. The bead has a through-passageway with axially opposite loop-entrance and loop-exit ends thereof located respectively at first and second opposite end surfaces of the bead. In one bead embodiment an external groove in a bead first side surface is sized for retaining a portion of each two runs of a free-end loop of the tension element disposed in side-by-side contacting relationship after exiting the passageway and lead in the groove toward engagement with trailing portions of the runs that trail back out the entrance end of the passageway as they extend back toward cargo holder attachment. To achieve this bead-held knotting, the loop bight and runs are trained over a second side surface of the bead until the loop bight contacts and crosses over the trailing run portions on the side thereof remote from the bead first side surface and generally where the trailing runs are leading toward entry into the bead passageway. While the bight remains caught by crossing over the trailing portions of the tension element runs, the exited portions of the loop runs are straddle spread back over the bead until they are seated into the bead groove. In another bead embodiment, the bead has a neck-like protrusion lassoed by the tension element loop after it is passed through the bead passageway. Retrograde tension force is exerted on the trailing run portions while restraining the bead cause snug engagement with the bead groove(s) due to the loop bight being caught across the trailing runs or neck-like protrusion to thereby securely but detachably affix the bead to the flexible tension element.
