Abstract:
The present invention is directed toward a quick attach and detach mechanism for a tool attachment such as a router attachment for a router. The attachment system includes a mounting adapter which may be integrally formed with the router housing or attached to the router housing as a bolt-on plate. The system works by vertically installing the tool attachment with the mounting adapter and then twisting to secure the tool attachment to the mounting adapter. A rotational lock is provided to prevent the tool attachment from inadvertently backing off or coming loose. This lock can be manually actuated to allow for quick detachment when desired. The tool attachment system is shown in association with a router which has several disclosed benefits, however there may also be applications of the system in other types of tool attachments for which coverage is also sought.
Abstract:
A removable surface positioning guide for a rotary hand-held tool provides one or more adjustable features for selective positioning of a surface engaging bit driven by the rotary hand-held tool. The surface positioning guide may include a pivot joint between a guide base and a mounting adapter. The guide base pivots relative to the mounting adapter about the pivot joint between operable positions. The surface positioning guide may include at least one spring supported by the mounting adapter either directly or indirectly that biases a guide base axially away from the mounting adapter. The guide base is movable toward the mounting adapter against the biasing of the at least one spring to effect a plunging movement. The surface positioning guide may include a reversible or interchangeable base flange with differently configured faces that are adapted to be placed against a working surface.
