Router attachment adaptor and cover for same

An attachment for a router having a bit, the attachment comprising:

• a frame arrangement having a top side and a bottom side, the frame arrangement having:
• an outer rim having a rim bottom most extent;
• a central hub located radially inward of the outer rim, the central hub having a hub bottom most extent, the central hub defining an opening configured to receive the bit therethrough along a central axis when the router is attached to the top side of the frame arrangement;
• a mounting portion extending radially between the outer rim and the central hub, the mounting portion having at least one mounting aperture therethrough;
• a bottom cover removably mountable to the frame arrangement radially between the central hub and the outer rim, the bottom cover covering the mounting portion;
• a rotation mounting arrangement provided in part by a first portion provided by the bottom cover and provided in part by a second portion provided by the frame arrangement, the rotation mounting arrangement having a first orientation wherein the bottom cover may be axially positionable relative to the frame arrangement parallel to the central axis and a second orientation wherein the bottom cover may not be removed from the frame arrangement axially parallel to the central axis and is axially secured to the frame arrangement;
• wherein:
• the first portion of the rotation mounting arrangement includes a first tab provided by the bottom cover;
• the second portion of the rotation mounting arrangement includes a second tab provided by the outer rim;
• the first and second tabs being angularly aligned with one another in the second orientation with the second tab being positioned axially further from the top side of the frame arrangement than the first tab;
• the outer rim includes a first axially extending notch angularly offset from the second tab;
• the outer rim includes a first relief axially above the second tab connected to the first axially extending notch;
• the first tab aligning with the first axially oriented notch and axially movable within the first axially oriented notch in the first orientation;
• and
• the first tab located within the first relief in the second orientation.

• a central hub located radially inward of the outer rim, the central hub having a hub bottom most extent, the central hub defining an opening configured to receive the bit therethrough along a central axis when the router is attached to the top side of the frame arrangement;
• a mounting portion extending radially between the outer rim and the central hub, the mounting portion having at least one mounting aperture therethrough;
• a bottom cover removably mountable to the frame arrangement radially between the central hub and the outer rim, the bottom cover covering the mounting portion;
• a rotation mounting arrangement provided in part by a first portion provided by the bottom cover and provided in part by a second portion provided by the frame arrangement, the rotation mounting arrangement having a first orientation wherein the bottom cover may be axially positionable relative to the frame arrangement parallel to the central axis and a second orientation wherein the bottom cover may not be removed from the frame arrangement axially parallel to the central axis and is axially secured to the frame arrangement;
• a locking member that has a locked configuration relative to the bottom cover and frame arrangement in which the locking member prevents rotation of the bottom cover from the second orientation to the first orientation;
• and
• wherein the locking member is in the form of a screw that extends through the bottom cover and threads into the frame arrangement when in the second orientation.

An adaptor attachment for a router having a bit, the adaptor attachment configured to attach the router to another component, the adaptor attachment comprising:

• a frame arrangement having a top side and a bottom side and a bit aperture extending through the frame and defining a central axis, the frame arrangement having:
• an outer rim having a first portion of a first rotational mounting arrangement configured to rotationally attach the frame arrangement to the another component;
• a mounting portion extending radially inward from the outer rim, the mounting portion having at least one mounting aperture therethrough;
• a bottom cover removably mountable to the frame arrangement to cover the mounting portion;
• a second rotation mounting arrangement having a first portion provided by the bottom cover and having a second portion provided by the frame arrangement, the rotation mounting arrangement having a first orientation wherein the bottom cover may be axially positionable relative to the frame arrangement parallel to the central axis and a second orientation wherein the bottom cover may not be removed from the frame arrangement axially parallel to the central axis and is axially secured to the frame arrangement.

An attachment for router, the attachment comprising:

• a frame arrangement having a top side and a bottom side, the frame arrangement having:
• an outer rim;
• a mounting portion attached to the outer rim, the mounting portion having at least one mounting aperture therethrough;
• a bottom cover removably mountable to the frame arrangement, the bottom cover covering the mounting portion with the mounting portion being closer to the router than the adjacent portion of the bottom cover when mounted to the router;
• a first rotation mounting portion provided by the bottom cover;
• a second rotation mounting portion provided by the frame arrangement, the first rotation mounting portion having a first orientation relative to the second rotation mounting portion wherein the bottom cover may be axially positionable relative to the frame arrangement parallel to the central axis, the first rotation mounting portion having a second orientation relative to the second rotation mounting portion wherein the first rotation mounting portion is angularly aligned with the second rotation mounting portion and the first rotation mounting portion axially abuts the second rotation mounting portion such that the bottom cover may not be removed from the frame arrangement axially parallel to the central axis and the bottom cover is axially secured to the frame arrangement;
• and
• wherein:
• the bottom cover includes a first angular abutment;
• the frame arrangement includes a second angular abutment;
• and
• first and second angular abutments angularly abut when the bottom cover is in the second orientation, the first and second angular abutments preventing the first rotation mounting portion from rotating past the second rotation mounting portion when the bottom cover is rotated in a direction to transition from the first orientation to the second orientation.
