Depth adjustment mechanism
First Claim
1. A depth adjustment mechanism for a power tool having a motor casing adjustably received in a base, the depth adjustment mechanism comprising:
- a rotation member;
a threaded shaft member coupled with the rotation member, and being received within a sleeve coupled to the base;
a rack member coupled with the casing, the rack member being selectively engaged by the threaded shaft member; and
a biasing assembly including a clamp with an arm that clamps over at least one of the threaded shaft member and the rack member to enable selective engagement of the threaded shaft member with the rack member,wherein the threaded shaft member and the rack member, when engaged, enable depth adjustment of the motor casing relative to the base.

Abstract
A depth adjustment mechanism, disposed on a router, is enabled using a worm drive that includes a shaft member engaging with a rack member. The shaft member couples with a sleeve disposed on a base of the router. The rack member is coupled with a motor casing of the router. The depth adjustment mechanism enables a user selectable engagement of the shaft member with the rack member. A rotating member, which is coupled with the shaft member, is engaged by a user to displace the shaft member relative to the rack member. The selective engagement of the shaft member with the rack member and rotation enabled by the rotating member enables continuous metered depth adjustment for the router.
