Abstract
A router depth adjustment device includes a shaft with a first and a second end, a handle disposed on the first end of the shaft, for rotating the shaft, and a mechanical connection disposed on the second end. The mechanical connection is configured to couple with a corresponding mechanical connection on a depth adjustment shaft of a router. A depth adjustment indexing system includes an adjustment knob slidably mounted on the shaft and an indexer pivotally mounted to the adjustment knob. The adjustment knob and the indexer are capable of pivoting independently and pivoting simultaneously. The adjustment knob is configured such that rotation of the adjustment knob rotates the shaft.
Claims15
A router depth adjustment device, comprising:
- a shaft with a first and a second end;
- a handle disposed on the first end of the shaft, for rotating the shaft;
- a mechanical connection disposed on the second end, the mechanical connection being configured to couple with a corresponding mechanical connection on a depth adjustment shaft of a router;
- and
- a depth adjustment indexing system including an adjustment knob slidably mounted on the shaft and an indexer pivotally mounted to the adjustment knob, wherein the adjustment knob and the indexer are capable of pivoting independently and pivoting simultaneously, the adjustment knob being configured such that rotation of the adjustment knob rotates the shaft.

A router system comprising:
- a router including a depth adjustment mechanism configured to make a depth adjustment on the router, the depth adjustment mechanism including a first shaft that rotates about an axis of the first shaft to make the depth adjustment;
- and
- an adjustment device above a top surface of a router table and configured to adjust the depth adjustment mechanism when the router is mounted beneath the top surface, the adjustment device comprising:
- a second shaft configured to pass through an aperture in the top surface, the second shaft having a top end portion with a handle that remains above the top surface and a bottom end portion with a mechanical connection that is configured to engage the first shaft such that rotation of the second shaft about an axis of the second shaft adjusts the depth adjustment mechanism;
- and
- an indexing system including an adjustment knob slidably mounted on the second shaft and an indexer pivotally mounted to the adjustment knob, wherein the adjustment knob and the indexer are capable of pivoting independently and pivoting simultaneously, the adjustment knob being configured such that rotation of the adjustment knob rotates the second shaft.

A router system comprising:
- a router including
- a motor housing portion including a motor and a router bit holder configured to hold a router bit;
- and
- a base portion movably coupled to the motor housing portion, the base portion configured to alternately be placed on a top side of a work surface of a workpiece or below an underside of the work surface;
- a depth adjustment mechanism configured to make a depth adjustment of a position of the motor housing portion relative to the base portion, the depth adjustment mechanism including a first shaft having a first end portion coupled to an adjustment knob, a threaded middle portion, and a second end portion coupled to a coupling element that includes a first hex fitting, the depth adjustment mechanism further including a thread receiving element that engages with the threaded middle portion of the shaft, wherein rotation of the knob or rotation of the coupling element rotates the first shaft about a longitudinal axis of the first shaft so that the threaded middle portion engages the thread receiving element to make the depth adjustment;
- and
- an adjustment wrench including
- a second shaft;
- a handle portion coupled to a first end of the second shaft;
- a second hex fitting coupled to a second opposite end of the second shaft, and
- an indexing mechanism including a first ring and a second ring slidably mounted along at least a portion of the second shaft, the second ring pivotable relative to the first ring and including a plurality of indicia for indicating a depth adjustment of the router, the first ring and the second ring being capable of pivoting independently and pivoting simultaneously,
- wherein when the base portion is placed below the underside of the work surface, the router bit is able to project through a first opening in a top surface of a router table, and the adjustment wrench second hex fitting is able to be removably inserted through a second opening in the top surface of the router table to removably engage the first hex fitting, so that rotation of the second shaft about a longitudinal axis of the second shaft causes rotation of the first shaft about a longitudinal axis of the first shaft to make said depth adjustment.
