LOPPING SHEARS WITH OFFSET BLADE

摘要

Loppers include first and second elongated handles that are both directly connected and indirectly connected through a linkage assembly. The first handle has a static blade having a concave shearing edge extending generally transverse from the longitudinal axis of the first handle. The second handle has a curved end portion that curves toward the first handle and is pivotally secured to the static blade. An articulated blade has a convex cutting edge and is rotatably secured to the static blade. A link connects the curved end portion to an end of the articulated blade. Movement of the second handle relative to the first handle pivots the curved end portion about the static blade, thereby moving the cutting edge relative to the shearing edge via the link. The static blade and articulate blade are offset from the handles and extend generally transverse to the longitudinal axis of the first handle.

主权项

1. A blade shear assembly comprising:
first and second elongate handles coupled to one another, the second handle having an end portion; a static blade extending generally transverse from the first handle, the static blade having a concave shearing edge, wherein the static blade is rotatably connected to the end portion of the second handle; an articulated blade rotatably connected to the static blade about an intermediate portion, the articulated blade having a first end and a second end extending in opposing directions from the intermediate portion, the first end having a convex cutting edge formed thereon and facing toward the concave shearing edge of the static blade such that the cutting edge and the shearing edge are offset from the handles; and a link coupling the end portion of the second handle to the second end of the articulated blade; wherein movement of the second handle relative to the first handle causes the end portion and link to rotate about the static blade such that the articulated blade rotates relative to the static blade about the intermediate portion.
