Abstract:
1. A router attachment system, comprising: a router including a router housing and a spindle, the spindle adapted to revolve relative to the housing about an axial axis; a mounting adapter along an end face of the router housing, the mounting adapter including an annular mounting surface; a router attachment including an attachment housing with an annular attachment surface that mates with the annular mounting surface; wherein the router attachment is rotatable between a release position and an attach position, the router attachment being removable from the mounting adapter in the release position, the router attachment axially engaging the mounting adapter in opposing directions along the axis in the attach position for axial retention of the router attachment; and a first snap structure on the mounting adapter and second snap structure on the router attachment, the first and second snap structures resiliently engaging at a predetermined angular position during transition between the release to the attach position, the first and second snaps creating pressure at the predetermined angular position that is released upon further movement past the predetermined angular position to provide a locking force that prevents relative rotation toward the release position when in the attach position.
