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 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 formed so as to provide sliding coupling with a corresponding mechanical connection included on a router; and
a depth adjustment indexing system including:
an adjustment knob traversely mounted to the shaft, such that the adjustment knob is positionable substantially along the entire length of the shaft; and
an indexer, including graduations, pivotally mounted to the adjustment knob;
wherein the adjustment knob and the indexer are capable of pivoting independently and pivoting simultaneously depending on user interaction, the adjustment knob being configured such that rotation of the adjustment knob rotates the shaft.
2. The router depth adjustment device of claim 1 , further comprising an interconnect mounted to the indexer, the interconnect being configured for coupling with a corresponding interconnect on a router table so as to prevent rotation of the indexer.
3. The router depth adjustment device of claim 2 , wherein an interconnect is at least one of a rib and a pin.
4. The router depth adjustment device 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.
5. The router depth adjustment device of claim 1 , wherein the adjustment knob is mounted to the shaft, such that the knob rotates with rotation of the shaft.
6. The router depth adjustment device of claim 1 , wherein the mechanical connection is a hex head.
7. The router depth adjustment device of claim 1 , wherein the mechanical connection is a socket.
8. The router depth adjustment device of claim 1 , wherein the mechanical connection is at least one of a slot head, a Phillips head and a Torx head.
9. A wrench, 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 formed so as to provide sliding coupling with a corresponding mechanical connection included on a router; and
a depth adjustment indexing system including:
an adjustment knob configured to slide substantially along the entire length of the shaft; and
an indexer, including graduations, pivotally mounted to the adjustment knob;
wherein the adjustment knob and the indexer are capable of pivoting independently and pivoting simultaneously depending on user interaction, the adjustment knob being configured such that rotation of the adjustment knob rotates the shaft.
10. The wrench of claim 9 , further comprising an interconnect mounted to the indexer, the interconnect being configured for coupling with a corresponding interconnect on a router table so as to prevent rotation of the indexer.
11. The wrench of claim 9 , further comprising a rubber plug disposed between the adjustment knob and indexer for alternately securing and unsecuring the indexer from the adjustment knob.
12. The wrench of claim 9 , wherein the adjustment knob is mounted to the shaft, such that the knob rotates with rotation of the shaft.
13. The wrench of claim 9 , wherein the mechanical connection is a hex head.
14. The wrench of claim 9 , wherein the mechanical connection is a socket.
15. A wrench, 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 formed so as to provide sliding coupling with a corresponding mechanical connection included on a power tool; and
a depth adjustment indexing system including:
an adjustment knob configured to slide substantially along the entire length of the shaft; and
an indexer, including graduations, pivotally mounted to the adjustment knob;
wherein the adjustment knob and the shaft are configured such that rotation of the adjustment knob rotates the shaft thereby rotating the corresponding mechanical connection included on a power tool.
16. The wrench of claim 15 , further comprising an interconnect mounted to the indexer, the interconnect being configured for coupling with a corresponding interconnect on a router table so as to prevent rotation of the indexer.
17. The wrench of claim 15 , further comprising a rubber plug disposed between the adjustment knob and indexer for alternately securing and unsecuring the indexer from the adjustment knob.
18. The wrench of claim 15 , wherein the adjustment knob is mounted to the shaft, such that the knob rotates with rotation of the shaft.
19. The wrench of claim 15 , wherein the mechanical connection is a hex head.
20. The wrench of claim 15 , wherein the mechanical connection is a socket.
