Abstract

A handle for use with a power tool includes a handle body, a beam and a weight. The handle body includes a mounting part and a grip part. The handle body is configured to be removably secured to a tool body of a power tool. The grip part is formed in an elongated hollow shape. The beam is supported by the handle body in a cantilever manner and extends within the grip part. The weight is supported by the beam.

First claim

What is claimed is:

1. A handle for use with a power tool, the handle comprising:
a handle body that includes (i) a mounting part configured to be removably secured to a tool body of the power tool, and (ii) an elongated hollow grip part fixed to the mounting part to be substantially immovable relative to the mounting part;
a beam that is supported by the handle body in a cantilever manner and that extends within the grip part; and
a weight that is supported by the beam, wherein:
the beam has (i) a first end portion that is coupled to the handle body and (ii) a second end portion that is opposite to the first end portion and has a free end of the beam, and
the weight is (i) supported on the second end portion of the beam and (ii) movable with the beam in a direction that intersects a longitudinal axis of the grip part while the weight is spaced apart from the grip part.

2. The handle as defined in claim 1 , wherein the beam is removably coupled to the handle body.

3. The handle as defined in claim 1 , wherein the weight is supported by the beam such that a position of the weight in an extension direction of the beam is changeable.

4. The handle as defined in claim 1 , wherein the weight is removably coupled to the beam.

5. The handle as defined in claim 1 , wherein the beam and the weight are coupled to each other to form a single assembly.

6. The handle as defined in claim 1 , wherein:
the grip part has (i) a first end portion that is closer to the mounting part and (ii) a second end portion that is farther from the tool body,
the beam is supported by the handle body at a position closer to the first end portion of the grip part than to the second end portion, and
the beam extends in a first direction that is directed from the first end portion of the grip part toward the second end portion.

7. The handle as defined in claim 6 , wherein the weight is supported by the beam outside of the second end portion of the grip part.

8. The handle as defined in claim 6 , wherein the beam is supported by the mounting part.

9. The handle as defined in claim 1 , wherein:
the grip part has (i) a first end portion that is closer to the mounting part and (ii) a second end portion that is farther from the tool body,
the beam is supported by the handle body at a position closer to the second end portion of the grip part than to the first end portion, and
the beam extends in a second direction that is directed from the second end portion of the grip part toward the first end portion.

10. The handle as defined in claim 1 , wherein the beam has different elastic deformation properties in different directions.

11. The handle as defined in claim 2 , wherein the weight is supported by the beam such that a position of the weight in an extension direction of the beam is changeable.

12. The handle as defined in claim 11 , wherein the weight is removably coupled to the beam.

13. The handle as defined in claim 12 , wherein:
the grip part has (i) a first end portion that is closer to the mounting part and (ii) a second end portion that is farther from the tool body,
the beam is supported by the handle body at a position closer to the first end portion of the grip part than to the second end portion, and
the beam extends in a first direction that is directed from the first end portion of the grip part toward the second end portion.

14. The handle as defined in claim 13 , wherein the weight is supported by the beam outside of the second end portion of the grip part.

15. The handle as defined in claim 12 , wherein:
the grip part has (i) a first end portion that is closer to the mounting part and (ii) a second end portion that is farther from the tool body,
the beam is supported by the handle body at a position closer to the second end portion of the grip part than to the first end portion, and
the beam extends in a second direction that is directed from the second end portion of the grip part toward the first end portion.

16. A power tool comprising:
a tool body; and
the handle as defined in claim 1 that is removably attached to the tool body.

17. The handle as defined in claim 1 , wherein:
the weight is coupled to the beam by threaded engagement such that a position of the weight in an the extension direction of the beam is changeable.

18. The handle as defined in claim 1 , wherein the beam is removably coupled to the handle body by threaded engagement.
