Power tool with base clamp
First Claim
1. A power tool comprising:
- a motor assembly;
a base assembly; and
a clamp assembly coupled to one of the motor assembly and the base assembly to selectively provide a retention force to the other of the motor assembly and the base assembly to removably couple the motor assembly and the base assembly, the clamp assembly including a handle member, a fulcrum member, and a biasing lever member, the biasing lever member including a first portion and a second portion disposed on opposite sides of the fulcrum member, the handle member rotatably coupled to the first portion of the biasing lever member, the handle member movable between an open position and a closed position, the handle member pivoting the first and second portions of the biasing lever member about the fulcrum member when moving from the open position to the closed position, causing the second portion of the biasing lever member to increase the retention force to removably couple the motor assembly and the base assembly, and the handle member pivoting the first and second portions of the biasing lever member about the fulcrum member when moving from the closed position to the open position, causing the second portion of the biasing lever member to reduce the retention force.

Abstract
A power tool includes a motor assembly, a base assembly, and a clamp assembly coupled to the motor assembly or the base assembly to selectively provide a retention force to the other to removably couple the motor assembly and the base assembly. The clamp assembly includes a handle member, a fulcrum member, and a biasing lever member. The lever member includes a first portion and a second portion disposed on opposite sides of the fulcrum member. The handle member is coupled to the first portion, and the handle member is movable between an open and closed position. The handle member rotates the first and second portions of the biasing lever member about the fulcrum member when moving from the open to the closed position, causing the second portion of the lever member to provide the retention force.

4. A power tool comprising:
-
a motor assembly; a base assembly; a clamp assembly coupled to one of the motor assembly and the base assembly to selectively provide a retention force to the other of the motor assembly and the base assembly to removably couple the motor assembly and the base assembly, the clamp assembly including a handle member, a fulcrum member, and a biasing lever member, the biasing lever member including a first portion and a second portion disposed on opposite sides of the fulcrum member, the handle member coupled to the first portion of the biasing lever member, the handle member movable between an open position and a closed position, the handle member rotating the first and second portions of the biasing lever member about the fulcrum member when moving from the open position to the closed position, causing the second portion of the biasing lever member to provide the retention force to removably couple the motor assembly and the base assembly, and the handle member rotating the first and second portions of the biasing lever member about the fulcrum member when moving from the closed position to the open position, causing the second portion of the biasing lever member to reduce the retention force; and further comprising an adjustment member moveably coupled to the one of the motor assembly and the base assembly, the adjustment member being moveable relative to the one of the motor assembly and the base assembly to change an amount of the retention force provided by the biasing lever member when the handle member is in the closed position. - View Dependent Claims (5, 6, 7, 8)

10. A power tool comprising:
-
a motor assembly; a base assembly; and a clamp assembly coupled to one of the motor assembly and the base assembly to selectively provide a retention force to the other of the motor assembly and the base assembly to removably couple the motor assembly and the base assembly, the clamp assembly including a handle member, a fulcrum member, and a biasing lever member, the biasing lever member including a first portion and a second portion disposed on opposite sides of the fulcrum member, the handle member rotatably coupled to the first portion of the biasing lever member, the handle member movable between an open position and a closed position, the handle member pivoting the first and second portions of the biasing lever member about the fulcrum member when moving from the open position to the closed position, causing the second portion of the biasing lever member to increase the retention force to removably couple the motor assembly and the base assembly, and the handle member pivoting the first and second portions of the biasing lever member about the fulcrum member when moving from the closed position to the open position, causing the second portion of the biasing lever member to reduce the retention force; and a clamp pad coupled to the second portion of the biasing lever member, the clamp pad selectively abutting the other of the base assembly and the motor assembly upon pivotal movement of the biasing lever member to apply the retention force and removably couple the base assembly and the motor assembly. - View Dependent Claims (11, 12, 13)

17. A router comprising:
-
a motor assembly; a base assembly defining an aperture and an axis; and a clamp assembly coupled to the base assembly to selectively provide a retention force to removably couple the motor assembly and the base assembly, the clamp assembly including a handle member with a pin coupled thereto, a fulcrum member fixed to the base assembly, a biasing lever member with a first portion having an end rotatably coupled to the pin, an adjustment member moveably coupled to the base assembly, and a clamp pad coupled to a second portion of the biasing member and being received by the aperture, the first and second portions of the biasing lever member disposed on opposite sides of the fulcrum member, the first portion of the biasing lever member being longer than the second portion, the handle member rotatable about an axis defined by the pin between an open position and a closed position, the handle member camming against the adjustment member when rotating from the open position to the closed position to thereby moving the pin away from the axis, moving the end of the first portion radially away from the axis, and pivoting the first and second portions of the biasing lever member about the fulcrum member, thereby resiliently deflecting the biasing lever member, thereby biasing the clamp pad against the motor assembly to increase the retention force, the adjustment member being moveable relative to the motor assembly to change an amount of the retention force provided by the biasing lever member when the handle member is in the closed position. - View Dependent Claims (18, 19)
