App. No. 17/232,316

Abstract

Claims (32)

1 . A hand tool comprising:

a head having a bell and a face for delivering an impact at a front end of the head; and

a handle operably coupled to the head and extending linearly away from the head along an axis,

wherein the bell is perimeter weighted such that a void space is disposed within the bell rearward of the face and spaced apart from peripheral edges of the bell and the face.

2 . The hand tool of claim 1 , wherein the void space is annular shaped, and

wherein an axis of the annular shaped void space is substantially perpendicular to an axis of the handle.

3 . The hand tool of claim 1 , wherein the head comprises a throat operably coupling the bell to the head,

wherein the bell comprises a stem portion extending rearward from a center of the bell behind the face toward the throat, and

wherein the void space is disposed between the peripheral edge of the bell and the stem portion.

4 . The hand tool of claim 3 , wherein a peripheral wall forms the peripheral edge of the bell.

5 . The hand tool of claim 4 , wherein the bell is removable and replaceable by another bell having a different weight than the bell.

6 . The hand tool of claim 5 , wherein the bell is removable and replaceable via operation of a first thread assembly on the stem portion and a second thread assembly on the throat.

7 . The hand tool of claim 5 , wherein the bell is removable and replaceable via operation of a first thread assembly on the peripheral wall and a second thread assembly on the throat.

8 . The hand tool of claim 5 , wherein a thickness of the peripheral wall is different between the bell and the other bell.

9 . The hand tool of claim 4 , wherein a thickness of the void space is larger than a thickness of the peripheral wall.

10 . The hand tool of claim 4 , wherein a thickness of the void space is smaller than a thickness of the peripheral wall.

11 . The hand tool of claim 3 , wherein a diameter of the throat is larger than a diameter of the stem portion.

12 . The hand tool of claim 3 , wherein a diameter of the stem portion is less than half a diameter of the face.

13 . The hand tool of claim 3 , wherein a gap is disposed between the stem portion and the throat.

14 . A bell supporting a striking face for an impact hand tool, the bell comprising:

a stem portion extending rearward from a center of the bell behind the striking face toward a throat operably coupling a head of the hammer to the bell; and

a peripheral wall spaced apart from the stem portion by a void space disposed therebetween,

wherein the peripheral wall provides perimeter weighting for the striking face.

15 . The bell of claim 14 , wherein the void space is annular shaped, and

wherein an axis of the annular shaped void space is substantially perpendicular to an axis of a handle of the hand tool.

16 . The bell of claim 14 , wherein the bell is removable and replaceable by another bell having a different weight than the bell.

17 . The bell of claim 16 , wherein the bell is removable and replaceable via operation of a first thread assembly on the stem portion and a second thread assembly on the throat.

18 . The bell of claim 16 , wherein the bell is removable and replaceable via operation of a first thread assembly on the peripheral wall and a second thread assembly on the throat.

19 . The bell of claim 16 , wherein a thickness of the peripheral wall is different between the bell and the other bell.

20 . The bell of claim 16 , wherein a thickness of the void space is larger than a thickness of the peripheral wall,

wherein a diameter of the throat is larger than a diameter of the stem portion, and

wherein a diameter of the stem portion is less than half a diameter of the striking face.
