Demolition hammer with reversible housing and interchangeable wear plate arrangement
A demolition hammer is provided that includes a housing that is reversible and a plurality of interchangeable wear plates. The demolition hammer may include a housing a housing having a first wall and a second wall opposite the first wall, and a power cell disposed within the housing, the power cell having a front face, wherein the housing is reversible such that the housing can be used with the power cell in a first orientation in which the front face faces the first wall and a second orientation in which the front face faces the second wall.
1. A demolition hammer, comprising:
a housing having a first wall and a second wall opposite the first wall,
a power cell disposed within the housing, the power cell having a front face, wherein the housing is reversible such that the housing can be used with the power cell in a first orientation in which the front face faces the first wall and a second orientation in which the front face faces the second wall; and
first and second wear plates, wherein the first and second wear plates are interchangeable and each of the first and second wear plates comprises a plate-like body having a first face, a second face generally parallel to the first face, the body defining a first pair of apertures positioned equidistant from a central longitudinal axis, each aperture configured to receive a first pin along a first axis and a second pin along a second axis, different than the first axis.
2. The demolition hammer of claim 1 , wherein each of the first and second wear plates comprises angled side edges adjacent the first face.
3. The demolition hammer of claim 2 , wherein the first axis is closer to the central longitudinal axis than the second axis.
4. The demolition hammer of claim 2 , wherein the body is symmetric about the central longitudinal axis.
5. The demolition hammer of claim 2 , wherein the body defines a second pair of apertures positioned equidistant from the central longitudinal axis, each aperture configured to receive a pin along a third axis, different than the first axis and the second axis.
6. The demolition hammer of claim 5 , wherein the third axis is approximately the same distance from the central longitudinal axis as the second axis.
7. The demolition hammer of claim 5 , wherein at least one of the first and second pairs of apertures is configured to receive pins of different shapes or sizes, nonconcurrently.
8. The demolition hammer of claim 1 , wherein at least one of the first or second wear plates include an angled top edge.
9. The demolition hammer of claim 1 , wherein at least one of the first or second wear plates include an angled side edge.
10. The demolition hammer of claim 1 , further including third and fourth wear plates, wherein all of the first, second, third, and fourth wear plates are interchangeable.
11. A demolition hammer, comprising:
a housing having a first wall and a second wall opposite the first wall,
a power cell disposed within the housing, the power cell having a front face, wherein the housing is reversible such that the housing can be used with the power cell in a first orientation in which the front face faces the first wall and a second orientation in which the front face faces the second wall;
a first wear plate interposed between the first wall and the power cell; and
a second wear plate interposed between the second wall and the power cell, wherein each of the first and second wear plates comprises a plate-like body having a first face, a second face generally parallel to the first face, the body defining a first pair of apertures positioned equidistant from a central longitudinal axis, each aperture configured to receive a first pin along a first axis and a second pin along a second axis, different than the first axis.
12. The demolition hammer of claim 11 , wherein each of the first and second wear plates comprises angled side edges adjacent the first face.
13. The demolition hammer of claim 12 , wherein the first axis is closer to the central longitudinal axis than the second axis.
14. The demolition hammer of claim 12 , wherein the body defines second pair of apertures positioned equidistant from the central longitudinal axis, each aperture configured to receive a pin along a third axis, different than the first axis and the second axis.
15. The demolition hammer of claim 14 , wherein the third axis is approximately the same distance from the central longitudinal axis as the second axis.
16. The demolition hammer of claim 14 , wherein at least one of the first and second pairs of apertures is configured to receive pins of different shapes or sizes, nonconcurrently.
17. The demolition hammer of claim 12 , wherein the body is symmetric about the central longitudinal axis.
18. The demolition hammer of claim 11 , wherein at least one of the first or second wear plates include an angled top edge.
19. The demolition hammer of claim 11 , wherein at least one of the first or second wear plates include an angled side edge.
20. The demolition hammer of claim 11 , further including third and fourth wear plates, wherein all of the first, second, third, and fourth wear plates are interchangeable.
