Abstract

A slide hammer bead breaker and wheel tipper tool includes a guide shaft, a weight slidably received within the guide shaft, and an impact head attached to an end of the guide shaft. The impact head includes a foot loop and a slot formed in each of two opposing sides, and includes a wedge protruding from an end opposite the guide shaft. The wedge is tapered and curved from the guide shaft to a tip, and includes a notch which separates the wedge into two wedge portions. Each foot loop is sized such that a user's foot can rest thereon.

First claim

What is claimed is:

1 . A tool for manipulating and changing a tire, the tire having a bead and a rim, the tool comprising:
a hollow shaft having a first end and a second end; a weight slidably received within the shaft and configured to slide through the first end of the shaft along a longitudinal direction, the weight including a first end, which is always disposed outside of the shaft, and a second end, which is always disposed inside the shaft; and an impact head fixedly attached to the second end of the shaft, the impact head including:
a first portion configured to engage with the bead of the tire; and
a second portion configured to engage with the rim of the tire.

2 . The tool of claim 1 , wherein the first portion includes a wedge tapered in a direction away from the second end of the shaft to a tip, the tip configured to contact the bead of the tire.

3 . The tool of claim 2 , wherein the wedge is concave in a direction facing a first side of the impact head.

4 . The tool of claim 1 , wherein the second portion includes at least one slot formed in one of a first side and a second side of the impact head, the second side opposite the first side.

5 . The tool of claim 4 , wherein the at least one slot comprises a first slot and a second slot, the first slot formed in the first side of the impact head, and the second slot formed in the second side of the impact head.

6 . The tool of claim 4 , wherein the impact head further includes at least one foot loop arranged nearer to the second end of the shaft than is the at least one slot.

7 . The tool of claim 6 , wherein the at least one foot loop is formed on one of the first side and the second side of the impact head.

8 . The tool of claim 6 , wherein the at least one foot loop comprises a first foot loop and a second foot loop, the first foot loop formed on the first side of the impact head, and the second foot loop formed on the second side of the impact head.

9 . The tool of claim 7 , wherein:
the at least one slot extends into the impact head in a first direction; and the at least one foot loop extends from the impact head in a second direction that is opposite the first direction.

10 . The tool of claim 9 , wherein:
the at least one slot comprises a first slot formed in the first side of the impact head in a first direction and a second slot formed in the second side of the impact head in a second direction, the first direction and the second direction opposite to one another; and the at least one foot loop comprises a first foot loop extending from the first side of the impact head in the second direction and a second foot loop extending from the second side of the impact head in the first direction.

11 . The tool of claim 1 , wherein:
the first portion includes a wedge tapered in a direction away from the second end of the shaft to a tip, the tip of the wedge has a wedge width extending from a first side of the impact head to a second side of the impact head, the first side opposite the second side; and the first portion further includes a notch formed in the tip of the wedge and having a notch width extending along a portion of the wedge width.

12 . The tool of claim 11 , wherein:
the wedge width is approximately seven times the notch width.

13 . The tool of claim 11 , wherein:
the second portion includes at least one slot formed in one of a third side and a fourth side of the impact head, the third side opposite the fourth side, the third side and the fourth side perpendicular to the first side and the second side; and the at least one slot has a slot width extending in a direction parallel to the wedge width; and the wedge width is approximately three and a half times the slot width.

14 . The tool of claim 13 , wherein:
the at least one slot has a slot length extending in a direction perpendicular to the slot width; and the slot width is approximately two times the slot length.

15 . The tool of claim 11 , wherein:
the impact head further includes at least one foot loop extending from the impact head; the at least one foot loop has a foot loop width extending in a direction parallel to the wedge width; and the wedge width is approximately 1 to 1.2 times the foot loop width.

16 . The tool of claim 15 , wherein:
the wedge width is approximately 1.17 times the foot loop width.

17 . The tool of claim 1 , wherein the shaft includes a feature configured to prevent the weight from being removed entirely from the first end of the shaft.

18 . The tool of claim 17 , wherein the weight includes a corresponding feature configured to cooperate with the feature of the shaft to prevent the weight from being removed entirely from the first end of the shaft.
