Divergent legged slide mount adapter

摘要

For use in a longitudinally elongated pipe having a pipe wall, the combination comprises first and second relatively slidably interconnectible structures, the first structure to be carried by the pipe wall, and the second structure adapted for lengthwise movement in the pipe; the structures having slidably interconnectible tongue and groove elements; a cam on one of the structures, and a guide on the other of the structures, are interengageable in response to lengthwise movement of the second structure, for relatively aligning the structures to enable slidable interconnection thereof. The guide may take the form of guiding and stabilizing legs.
