Drill stand
A drill stand including 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, a carriage moveably coupled to the mast, and a release valve. The base has, 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. The release valve is in fluid communication with the vacuum chamber. Ambient air at atmospheric pressure is permitted to enter the vacuum chamber in response to actuation of the release valve.
1 . A drill stand comprising:
a base, the base having, 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;
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;
a carriage moveably coupled to the mast; and
a release valve in fluid communication with the vacuum chamber, wherein ambient air at atmospheric pressure is permitted to enter the vacuum chamber in response to actuation of the release valve.
2 . The drill stand of claim 1 , wherein the release valve extends from a side wall of the base to the vacuum chamber.
3 . The drill stand of claim 2 , further comprising a port arranged on the underside of the base in fluid communication with the vacuum chamber, wherein the port is 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.
4 . The drill stand of claim 3 , wherein the port extends from a top side of the base to the vacuum chamber.
5 . The drill stand of claim 1 , wherein the base includes a wear plate having an elongated slot sized to receive a mounting bolt that is configured to secure the base to the mounting surface.
6 . The drill stand of claim 5 , wherein the second gasket is outside the elongated slot and inside the first gasket.
7 . The drill stand of claim 1 , wherein the first gasket is proximate an outer sidewall of the base.
8 . The drill stand of claim 7 , wherein the base includes a plurality of screws moveable relative to the base to adjust a height and/or orientation of the base with respect to the mounting surface, and wherein the screws are positioned outside the first gasket.
9 . A drill stand comprising:
a base, the base having 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;
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;
a carriage moveably coupled to the mast; and
a port 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 the second gasket are engaged with the mounting surface.
10 . The drill stand of claim 9 , wherein the base includes a recess configured to receive a bolt extending through the support bracket when the mast and the support bracket are moved to a collapsed configuration.
11 . The drill stand of claim 9 , wherein the base includes a wear plate having an elongated slot sized to receive a mounting bolt that is configured to secure the base to the mounting surface.
12 . The drill stand of claim 10 , wherein the second gasket is outside the elongated slot and inside the first gasket.
13 . The drill stand of claim 9 , wherein the port extends from a top side of the base to the vacuum chamber.
14 . The drill stand of claim 13 , wherein the port protrudes from the top side of the base.
15 . The drill stand of claim 9 , wherein the support bracket is moveably coupled to the mast via a tool-free clamping mechanism that selectively locks the support bracket to the mast.
16 . A drill stand comprising:
a base, the base having, 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;
a mast defining a longitudinal axis and pivotably coupled to the base;
a carriage moveably coupled to the mast;
a port 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 the second gasket are engaged with the mounting surface; and
a release valve in fluid communication with the vacuum chamber, wherein ambient air at atmospheric pressure is permitted to enter the vacuum chamber in response to actuation of the release valve.
17 . The drill stand of claim 16 , wherein the release valve extends from a side wall of the base to the vacuum chamber.
18 . The drill stand of claim 16 , wherein the port extends from a top side of the base to the vacuum chamber.
19 . The drill stand of claim 16 , wherein the base includes a wear plate having an elongated slot sized to receive a mounting bolt that is configured to secure the base to the mounting surface.
20 . The drill stand of claim 19 , wherein the second gasket is outside the elongated slot and inside the first gasket.
