Router plunge depth adjustment mechanism
View Patent ↗The present invention is directed to a mechanism and method for providing base end plunge router depth adjustment, such as when a router is utilized with a router table. The apparatus and method of the present invention permits accurate and efficient depth adjustment when utilizing a router with a router table. A router depth adjustment device includes an adjustment knob and indexer, so users are provided with the ability for measured depth adjustment.
1. A router table depth adjustment system, 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;
a depth adjustment indexing system including:
an adjustment knob traversely mounted to the shaft; and
an indexer, including a mechanical interconnect, pivotally mounted to the adjustment knob;
a support surface, including a first and a second side with an aperture therethrough suitable for receiving the mechanical connection, said support surface including:
a mechanical interconnect formed in the first side, adjacent to the aperture, for receiving the mechanical interconnect included on the indexer; and
an indicator adjacent the aperture suitable for aligning the depth adjustment indexing system; and
means for supporting the support surface coupled to the second side;
wherein the router table depth adjustment system permits measured router depth adjustment from the first side.
2. The router table depth adjustment system of claim 1 , wherein an indexer interconnect is at least one of a rib and a pin.
3. The router table depth adjustment system of claim 1 , further comprising a rubber plug disposed between the adjustment knob and indexer for alternately securing and unsecuring the indexer to the adjustment knob.
4. The router table depth adjustment system of claim 1 , wherein the adjustment knob is mounted to the shaft, such that the knob rotates with rotation of the shaft.
5. The router table depth adjustment system of claim 1 , wherein the mechanical connection is a hex head.
6. The router table depth adjustment system of claim 1 , wherein the mechanical connection is a socket.
7. The router table depth adjustment system of claim 1 , wherein the mechanical connection is at least one of a slot head, a Phillips head and a Torx head.
