<p>A guard (50) is provided for a joint between first (12) and second (14) pivotally interconnected members. The members (12, 14) are pivotable from a first position to a second position about a pivot axis (82) on one side of the members (12, 14), thereby creating a gap between the two members. The gap has a widest part opposite the pivot axis and sides of the gap extend between the widest part and the pivot axis. The guard (50) includes a plurality of shroud portions (52, 54, 56, 58). Each shroud portion (52, 54, 56, 58) is formed as a partial enclosure including side wall portions (66, 72) on opposite sides of the gap. The partial enclosure extends continuously from one side of the gap to the other side of the gap including across the widest part of the gap. The plurality of shroud portions (52, 54, 56, 58) are nested together when the members (12, 14) are in the first position and are movable relatively apart to form a shroud over the widest part and the sides of the gap when the members (12, 14) are in the second position.</p> |
