Abstract
A tool support incorporates height adjustment and locking features in common components. A pivoting door is used to control the engagement of a height adjustment threaded shaft with the bearing flange of the power tool, with the position of the pivoting door controlled by a manual actuator. In one position the manual actuator allows the door to pivot outward to disengage the height adjustment shaft from the bearing flange. In a second position the manual actuator moves the door to engage the height adjustment shaft with the bearing flange to permit “micro” height adjustment by rotation of the height adjustment shaft. In a third position the manual actuator presses the door into the height adjustment shaft to effectively lock the shaft in position.
Claims19
A tool support for supporting a power tool at adjustable heights, the power tool having an elongated body supporting a working tool, said tool support comprising:
- a base configured to rest on a work surface;
- a clamping cuff connected to said base, said clamping cuff configured to receive the elongated body of the power tool therethrough at adjustable heights above the work surface;
- a bearing flange associated with the elongated body of the power tool, said bearing flange in sliding engagement with said clamping cuff;
- said clamping cuff defining an opening with said bearing flange accessible through said opening;
- a door movably mounted to said clamping cuff for movement toward said bearing flange through said opening;
- said door and said bearing flange each including a threaded half-bore that together forming a threaded bore when said door is directly adjacent said bearing flange;
- a threaded shaft disposed between said door and said bearing flange and configured to threadedly engage said threaded half-bore in said bearing flange when said door and said bearing flange are directly adjacent such that rotation of said threaded shaft adjusts a height of the elongated body of the power tool relative to said base;
- and
- an actuator for selectively moving said door and said bearing flange directly adjacent to form said threaded bore.
