Blade for removing material from surfaces
View Patent ↗A blade is provided having runners on the blade that extend forward of the blade's leading edge. These runners traverse surface irregularities allowing the blade to avoid colliding with surface irregularities.
1. A blade comprising:
an elongated member having a first end and a second end spaced apart from the first end, and a blade body, the blade body configured to receive the second end of the elongated member, wherein the blade body includes
a first surface;
a second surface disposed opposite the first surface;
a first side having a first profile and a second side having a second profile, with the second side disposed opposite and substantially parallel to the first side,
a first edge extending between the first side and the second side,
a second edge spaced apart from the first edge extending between the first side and the second side,
a first runner attached to the first side, the first runner having a first runner profile at least partially defined by the first profile and the first runner extending beyond the second edge, the first runner profile being vertically offset from the first profile, such that a portion of the first runner extends beneath the first side.
2. The blade of claim 1 further comprises:
a second runner attached to the second side, the second runner having a second runner profile at least partially defined by the second profile and the second runner extending beyond the second edge, the second runner disposed substantially parallel to the first runner.
3. The blade of claim 2 wherein the second runner profile has an arcuate profile that substantially matches the second profile.
4. The blade of claim 2 wherein at least a portion of the second runner abuts and is disposed perpendicular to the second surface.
5. The blade of claim 1 further comprises:
a blade body profile
a blade body runner attached to the blade body, the blade body runner having a blade body runner profile at least partially defined by the blade body profile and the blade body runner extending beyond the second edge, the blade body runner disposed substantially parallel to the first runner.
6. The blade of claim 5 wherein the blade body runner profile has an arcuate profile that substantially matches the blade body profile.
7. The blade of claim 5 wherein at least a portion of the blade body runner abuts and is disposed perpendicular to the second surface.
8. The blade of claim 1 wherein the first runner profile has an arcuate profile that substantially matches the first profile.
9. The blade of claim 1 wherein at least a portion of the first runner abuts and is disposed perpendicular to the second surface.
10. The blade of claim 1 , wherein the first runner is offset from at least one of the first surface and the second surface.
11. A blade body comprising:
a first surface;
a second surface disposed opposite the first surface;
a first side having a first profile;
a second side having a second profile and disposed opposite and substantially parallel to the first side;
the first surface and second surface define an edge extending between the first side and the second side;
a blade body profile; and
a first runner attached to the first side, the first runner having a first runner profile at least partially defined by the first profile and the first runner extending beyond the edge, wherein the first runner profile being vertically offset from the first profile, such that the first runner is offset from at least one of the first surface and the second surface, and a portion of the first runner extends beneath the first side.
12. The blade body of claim 11 further comprises a second runner attached to the second side, the second runner having a second runner profile at least partially defined by the second profile and the second runner extending beyond the edge, the second runner disposed substantially parallel to the first runner.
13. The blade body of claim 12 wherein the first runner profile has an arcuate profile that substantially matches the first profile.
14. The blade body of claim 12 wherein at least a portion of the first runner abuts and is disposed perpendicular to the second surface.
15. The blade body of claim 12 wherein the second runner profile has an arcuate profile that substantially matches the second profile.
16. The blade body of claim 12 wherein at least a portion of the second runner abuts and is disposed perpendicular to the second surface.
17. The blade body of claim 11 further comprises a blade body runner attached to the blade body, the blade body runner having a blade body runner profile at least partially defined by the blade body profile and the blade body runner extending beyond the edge, the blade body runner disposed substantially parallel to the first runner.
18. The blade body of claim 17 wherein the blade body runner profile has an arcuate profile that substantially matches the blade body profile.
19. The blade body of claim 17 wherein at least a portion of the blade body runner abuts and is disposed perpendicular to the second surface.
