Abstract
A rock claw for attaching to a corner of a demolition hammer, the rock claw including a first wall having a first inner side surface, a second wall having a second inner side surface joined to the first inner side surface along a first intersection, and a third wall having a third inner side surface. The third inner side surface is joined to the first inner side surface along a second intersection and the third inner side surface is joined to the second inner side surface along a third intersection.
Claims26
A rock claw for attaching to a corner of a demolition hammer, the rock claw comprising:
- a first wall having a first inner side surface;
- a second wall having a second inner side surface joined to the first inner side surface along a first intersection;
- and
- a third wall having a third inner side surface, the third inner side surface joined to the first inner side surface along a second intersection and the third inner side surface joined to the second inner side surface along a third intersection;
- wherein the first wall has a height that is larger adjacent the first intersection than at a location that is more distal from the first intersection.
A demolition hammer, comprising:
- a housing having first side wall, a second side wall, and a bottom wall, wherein an intersection of the first side wall, the second side wall, and the bottom wall define a corner;
- a power cell positioned within the housing;
- a tool disposed in the power cell and projecting from the housing through an opening in the bottom wall;
- and
- a rock claw attached to an external surface of the housing, the rock claw comprising:
- a first wall;
- a second wall joined to the first wall;
- and
- a third wall joined to both the first wall and the second wall;,
- wherein the first wall of the rock claw covers a portion of the first side wall of the housing, the second wall of the rock claw covers a portion of the second side wall of the housing, and the third wall cover of the rock claw covers a portion of the bottom wall of the housing, and
- wherein the housing first side wall of the housing has a height and the first wall of the rock claw extends further along the height of the first side wall of the housing at a location adjacent the second side wall of the housing than at a location on the first side wall of the housing that is more distal from the second side wall of the housing.
A rock claw for attaching to a corner of a demolition hammer, the rock claw comprising:
- a first wall having a first inner side surface;
- a second wall having a second inner side surface joined to the first inner side surface along a first intersection;
- and
- a third wall having a third inner side surface, the third inner side surface joined to the first inner side surface along a second intersection and the third inner side surface joined to the second inner side surface along a third intersection,
- wherein the rock claw is symmetric along an axis defined by the first intersection.
