Abstract

A drill stand comprises a base, a mast defining a longitudinal axis and pivotably coupled to the base, a support bracket moveably coupled to the mast and pivotably coupled to the base, and a carriage moveably coupled to the mast. The carriage is configured to selectively receive a drill and is selectively removable from the mast in a tool-free manner.

First claim

What is claimed is:

1. A drill stand comprising:
a base;
a mast defining a longitudinal axis and pivotably coupled to the base;
a support bracket moveably coupled to the mast and pivotably coupled to the base; and
a carriage moveably coupled to the mast,
wherein the carriage is configured to selectively receive a drill and is selectively removable from the mast in a tool-free manner.

2. The drill stand of claim 1 , wherein the carriage is removable from the mast in a direction parallel to the longitudinal axis.

3. The drill stand of claim 2 , wherein the mast defines a groove in a direction parallel with the longitudinal axis, wherein the carriage includes a roller arranged in the groove, and wherein the roller rolls along the groove in response to the carriage moving relative to the mast in a direction parallel with the longitudinal axis.

4. The drill stand of claim 1 , wherein the mast and support bracket are collapsible relative to the base.

5. The drill stand of claim 4 , wherein the mast and support bracket are movable to a collapsed configuration in which at least one of the mast or the support bracket is substantially parallel with the base.

6. The drill stand of claim 5 , wherein one of the mast or the support bracket includes a bolt, and wherein the base includes a recess configured to receive the bolt when the mast and the support bracket are moved to the collapsed configuration.

7. The drill stand of claim 1 , wherein the base includes, on a bottom side thereof, a first gasket and a second gasket disposed within the first gasket, such that a vacuum chamber is defined between the first gasket, the second gasket, the bottom side of the base, and a mounting surface on which the base is configured to be mounted, and wherein a port is arranged on the underside of the base in fluid communication with the vacuum chamber, the port configured to be coupled to a vacuum source such that a vacuum may be created in the vacuum chamber when the first gasket and second gasket are engaged with the mounting surface.

8. The drill stand of claim 7 , wherein the base includes a valve in fluid communication with the vacuum chamber, and wherein ambient air at atmospheric pressure is permitted to enter the vacuum chamber in response to actuation of the valve.

9. The drill stand of claim 1 , wherein the base includes a plurality of screws moveable relative to the base to adjust the height and orientation of the base with respect to a mounting surface on which the base is configured to be mounted.

10. The drill stand of claim 9 , wherein the mast includes a bubble level for indicating the orientation of the mast relative to the mounting surface.

11. The drill stand of claim 1 , wherein the base includes a handle, and wherein the support bracket is configured to be locked with respect to the base and the mast, such that an operator may carry the drill stand with the handle and/or the support bracket.

12. The drill stand of claim 1 , wherein the base includes a pair of handles located on opposite sides of the base.

13. The drill stand of claim 1 , wherein the mast includes a rack, wherein the carriage includes a pinion engaged with and moveable along the rack and a handle which, when rotated, applies torque to the pinion causing it to rotate and move along the rack, causing the carriage to move relative to the mast.

14. The drill stand of claim 13 , further comprising a brake mechanism configured to prevent the pinion from moving along the rack absent an external force applied to the handle.

15. The drill stand of claim 14 , wherein the brake mechanism comprises a spindle coupled for co-rotation with the handle, a bushing fixed on the carriage, and a biasing member that biases the spindle against the bushing with a predetermined force.

16. The drill stand of claim 14 , wherein the pinion is press fit to a spindle that rotates in response to rotation of the handle, such that in response to rotation of the handle, the pinion rotates and moves along the rack.
