Router adjustment ring
First Claim
1. A height adjustment ring assembly for adjusting height of a router motor housing relative to a router base, the router being movable between upright and inverted positions, the housing having external threads formed thereon, the height adjustment ring assembly comprising:
- a support member secured to the router base, said support member having a radially extending flange portion;
an annular adjustment ring having an internal thread for cooperation with the external threads for height adjustment; and
means for entrapping the flange portion with respect to the adjustment ring, thereby limiting relative axial movement while allowing free relative rotation of the adjustment ring with respect to the support member for adjustment of the router motor housing regardless of router position.

Abstract
The height adjustment ring assembly is provided for adjusting height of a router motor housing relative to a router body, the router being movable between upright and inverted positions. The housing includes external threads formed thereon. The height adjustment ring assembly comprises a support member secured to the router base, the support having a radially extending flange portion. An annular adjustment ring includes an internal thread for cooperation with the external threads. Means for entrapping the flange portion with respect to the adjustment ring is provided, thereby limiting relative axial movement while allowing free relative rotation of the adjustment ring with respect to the support member for adjustment of the router motor housing regardless of router position. First and second zero reset rings are rotatably secured to the adjustment ring for relative rotation with respect to the adjustment ring, each reset ring having indicia formed thereon to facilitate accurate adjustment of the motor housing with respect to the router base in both the upright and inverted positions.

8. A height adjustment ring assembly for adjusting height of a router motor housing relative to a router base of an invertible router, the housing having external threads formed thereon, the height adjustment ring assembly comprising:
-
a support member secured to the router base, said support member having a radially extending flange portion; an annular adjustment ring having an internal thread for cooperation with the external threads; and an annular retainer secured to said adjustment ring and having an inwardly extending rim, whereby the flange portion of said support member is entrapped between said rim and said adjustment ring, thus limiting relative axial movement while allowing free relative rotation for adjustment of the router motor housing relative to the router base regardless of router position. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A height adjustment ring assembly for adjusting the height of a router motor housing relative to a router base, the router being movable between upright and inverted positions, the housing having external threads formed thereon, the height adjustment ring assembly comprising:
-
a support member secured to the router base, said support member having a radially extending flange portion; an annular adjustment ring having an internal thread for cooperation with the external threads, said adjustment ring forming a plurality of apertures therethrough; an annular retainer having a plurality of latches extending therefrom for cooperation with said apertures, and having an inwardly extending rim, whereby the flange portion of said support member is entrapped between said rim and said adjustment ring, limiting relative axial movement while allowing free relative rotation of the adjustment ring with respect to the support member for adjustment of the router motor housing regardless of router position; first and second zero reset rings rotatably secured to said adjustment ring for relative rotation between the adjustment ring and the respective zero reset ring, each said zero reset ring having indicia formed thereon; and first and second reference markers secured with respect to the router base adjacent the first and second zero reset rings, respectively, thus facilitating accurate adjustment of the motor housing with respect to the router base in both the upright and inverted positions.
