Abstract

An auxiliary handle can be used with a power tool having a housing that includes a first notch and a second notch. The auxiliary handle includes a shaft, a first clamp coupled to the shaft and having a first protrusion configured to engage the first notch, a second clamp arranged on the shaft and having a second protrusion configured to engage the second notch, and a grip coupled to the shaft. When the first protrusion of the first clamp engages the first notch and the grip is rotated relative to the second clamp, the second clamp is moved toward the first clamp, such that the first protrusion engages the first notch and the second protrusion engages the second notch to couple the auxiliary handle to the housing of the power tool.

First claim

What is claimed is:

1. An auxiliary handle for use with a power tool having a housing that includes a first notch and a second notch, the auxiliary handle comprising:
a shaft defining a shaft axis;
a first clamp coupled to the shaft and having a first body portion extending along the shaft axis, a first leg portion extending from the first body portion in a direction transverse to the first body portion, and a first protrusion extending from an end of the first leg portion furthest from the shaft axis in a direction transverse to the first leg portion, the first protrusion configured to engage the first notch;
a second clamp arranged on the shaft and having a second body portion extending along the shaft axis, a second leg portion extending from the second body portion in a direction transverse to the second body portion, and a second protrusion extending from an end of the second leg portion furthest from the shaft axis in a direction transverse to the second leg portion, the second protrusion configured to engage the second notch; and
a grip coupled to the shaft,
wherein when the first protrusion of the first clamp engages the first notch and the grip is rotated relative to the second clamp, the second clamp is moved toward the first clamp, such that the first protrusion engages the first notch and the second protrusion engages the second notch to couple the auxiliary handle to the housing of the power tool, and
wherein a first recess is defined between the first body portion and the first protrusion, and wherein a first nose portion adjacent the first notch of the housing is configured to be received in the first recess when the first protrusion engages the first notch, such that the first protrusion is inhibited from disengaging from the first notch.

2. The auxiliary handle of claim 1 , wherein the first leg portion extends in a direction perpendicular to the shaft, and wherein the second leg portion extends in direction perpendicular to the shaft.

3. The auxiliary handle of claim 2 , wherein the first protrusion extends in a direction that is substantially parallel with the shaft, and wherein the second protrusion extends in direction that is substantially parallel with the shaft.

4. The auxiliary handle of claim 1 , wherein a second recess is defined between the second body portion and the second protrusion, and wherein a second nose portion adjacent the second notch of the housing is configured to be received in the second recess when the second protrusion engages the second notch, such that the first protrusion is inhibited from disengaging from the second notch.

5. An auxiliary handle for use with a power tool having a housing that includes a first notch and a second notch, the auxiliary handle comprising:
a shaft defining a shaft axis;
a first clamp arranged on the shaft and having a first body portion extending along the shaft axis, a first leg portion extending from the first body portion in a direction transverse to the first body portion, and a first protrusion extending from an end of the first leg portion furthest from the shaft axis in a direction transverse to the first leg portion, the first protrusion configured to engage the first notch;
a second clamp arranged on the shaft and having a second body portion extending along the shaft axis, a second leg portion extending from the second body portion in a direction transverse to the second body portion, and a second protrusion extending from an end of the second leg portion furthest from the shaft axis in a direction transverse to the second leg portion, the second protrusion configured to engage the second notch; and
a grip coupled to the shaft,
wherein in response to rotation of the grip relative to the first and second clamps, the first and second clamps are moved toward each other, such that the first protrusion can engage the first notch and the second protrusion can engage the second notch to couple the auxiliary handle to the housing of the power tool, and
wherein a first recess is defined between the first body portion and the first protrusion, and wherein a first nose portion adjacent the first notch of the housing is configured to be received in the first recess when the first protrusion engages the first notch, such that the first protrusion is inhibited from disengaging from the first notch.

6. The auxiliary handle of claim 5 , wherein the first leg portion extends in a direction perpendicular to the shaft, and wherein the second leg portion extends in direction perpendicular to the shaft.

7. The auxiliary handle of claim 6 , wherein the first protrusion extends in a direction that is substantially parallel with the shaft, and wherein the second protrusion extends in direction that is substantially parallel with the shaft.

8. The auxiliary handle of claim 7 , wherein the first body portion includes a first passageway through which the shaft extends.

9. The auxiliary handle of claim 5 , wherein a second recess is defined between the second body portion and the second protrusion, and wherein a second nose portion adjacent the second notch of the housing is configured to be received in the second recess when the second protrusion engages the second notch, such that the first protrusion is inhibited from disengaging from the second notch.

10. An auxiliary handle for use with a power tool having a housing that includes a first notch and a second notch, the auxiliary handle comprising:
a shaft defining a shaft axis;
a first clamp arranged on the shaft and having first body portion extending along the shaft axis, a first leg portion extending from the first body portion in a direction transverse to the first body portion, and a first protrusion extending from an end of the first leg portion furthest from the shaft axis in direction transverse to the first leg portion, the first protrusion configured to engage the first notch, the first clamp movable along the shaft between a first position in which the first protrusion engages the first notch, and a second position in which the first protrusion does not engage the first notch;
a second clamp arranged on the shaft and having a second body portion extending along the shaft axis, a second leg portion extending from the second body portion in a direction transverse to the second body portion, and a second protrusion extending from an end of the second leg portion furthest from the shaft axis in a direction transverse to the second leg portion, the second protrusion configured to engage the second notch, the second clamp movable between a first position in which the second protrusion engages the second notch, and a second position in which the second protrusion does not engage the second notch; and
a grip coupled to the shaft, wherein in response to rotation of the grip relative to the first and second clamps, the first and second clamps are respectively moved to their first positions, such that the handle is coupled to the housing of the power tool,
wherein a first recess is defined between the first body portion and the first protrusion, and
wherein a first nose portion adjacent the first notch of the housing is configured to be received in the first recess when the first protrusion engages the first notch, such that the first protrusion is inhibited from disengaging from the first notch.

11. The auxiliary handle of claim 10 , wherein the first leg portion extends in a direction perpendicular to the shaft, and wherein the second leg portion extends in direction perpendicular to the shaft.

12. The auxiliary handle of claim 11 , wherein the first protrusion extends in a direction that is substantially parallel with the shaft, and wherein the second protru
