PIPE CUTTING APPARATUS HAVING A HAND GUARD
A pipe cutting apparatus having a hand guard is described. The hand guard comprises a body, the body including: a top surface having a curved shape; a bottom surface having a curved shape, wherein the top surface and the bottom surface form an extended end having a wedge shape; an engagement surface having a curved shape and extending from the bottom surface, and an attachment portion. The body also comprises a first recess having a curved shape, wherein the first recess is disposed between the attachment portion and the extended end. The hand guard can prevent an operator's hand from being caught in a pinch area between a pipe cutting tool and the housing.
1 . A pipe cutting apparatus, comprising:
a) a generally circular frame having a circumferential frame surface;
b) a tool carrier rotatably coupled to the frame;
c) a tool support coupled to and rotatable with the tool carrier;
d) a housing coupled to the frame and extending radially outward from the circumferential frame surface, wherein the housing has an outer housing surface; and
e) a hand guard disposed on the circumferential frame surface.
2 . The pipe cutting apparatus of claim 1 , wherein the hand guard comprises:
i. a body, the body including:
A. a top surface having a curved shape,
B. a bottom surface having a curved shape and disposed adjacent to the circumferential frame surface, wherein the top surface and the bottom surface form an extended end having a wedge shape,
C. an engagement surface having a concave shape and disposed adjacent to the outer housing surface, and
D. an attachment portion that attaches the hand guard to circumferential frame surface of the frame; and
ii. a first recess formed by the engagement surface and configured to fit on the housing, wherein the first recess is disposed between the attachment leg and the extended end.
3 . The pipe cutting apparatus of claim 2 , wherein the hand guard is reversibly mounted on the circumferential frame surface.
4 . The pipe cutting apparatus of claim 2 , wherein the attachment portion is an attachment plate that is reversibly mounted on the circumferential frame surface of the frame.
5 . The pipe cutting apparatus of claim 2 , wherein the housing has a center and an axis radially passing through the center to divide the housing and the hand guard into a first side and a second side, wherein the extended end of the hand guard is on the first side, and wherein the attachment portion is an attachment leg that abuts the circumferential frame surface on the second side.
6 . A hand guard configured to be coupled to a pipe cutting apparatus having a circumferential frame and surface housing, the hand guard comprising:
a) a body, the body including:
i. a top surface having a curved shape,
ii. a bottom surface having a curved shape, wherein the top surface and the bottom surface form an extended end having a wedge shape,
iii. an engagement surface having a curved shape and extending from the bottom surface, and
iv. an attachment portion, and
b) a first recess having a curved shape, wherein the first recess is disposed between the attachment portion and the extended end.
7 . The pipe cutting apparatus of claim 6 , wherein the attachment portion is an attachment plate that is reversibly mounted on the circumferential frame surface of the frame.
8 . The pipe cutting apparatus of claim 6 , wherein the surface housing has a center and an axis radially passing through the center to divide the surface housing and the hand guard into a first side and a second side, wherein the extended end of the hand guard is on the first side, and wherein the attachment portion is an attachment leg that abuts the circumferential frame surface on the second side.
