Lopping shears

摘要

A lopper includes a first metal plate including a first gear structure and a first elongate extension, a second metal plate including a second gear structure in meshing engagement with said first gear structure and a second elongate extension, a first handle coupled to said first elongate extension, a second handle coupled to said second elongate extension, a link to which each of said first body and said second body is pivotably connected so that said first gear structure and said second gear structure are retained in meshing engagement, a first metal blade member having a first arm portion, a first cutting portion, and a first intermediate portion interposed between said first arm portion and said first cutting portion, and a second metal blade member having a second arm portion, a second cutting portion, and a second intermediate portion interposed between said second arm portion and said second cutting portion.

主权项

1. A lopper, comprising:
a first metal plate including (i) a first body having a first gear structure disposed at an end of the first body, said first gear structure including first teeth and a first stop, (ii) a first elongate extension extending from said first body, and (iii) said first body, said first teeth, and said first elongate extension include a generally flat and uniform thickness; a second metal plate including (i) a second body having a second gear structure disposed at an end of the second body, said second gear structure including second teeth positioned in meshing engagement with said first teeth of said first gear structure, and a second stop, and (ii) a second elongate extension extending from said second body, and (iii) said second body, said second teeth, and said second elongate extension include a generally flat and uniform thickness; a first handle coupled to said first elongate extension of said first metal plate, wherein said first elongate extension is centrally disposed along a first longitudinal axis of said first handle; a second handle coupled to said second elongate extension of said second metal plate, wherein said second elongate extension is centrally disposed along a second longitudinal axis of said second handle; a link to which each of said first body and said second body is pivotably connected so that said first teeth of said first gear structure and said second teeth of said second gear structure are retained in said meshing engagement with each other, and wherein said first body and said second body are aligned along a same plane and said link is disposed on a first side of said first body and second body; a first metal blade member having (i) a first arm portion, (ii) a first cutting portion defining a first cutting surface, and (iii) a first intermediate portion interposed between said first arm portion and said first cutting portion, wherein said first metal blade member is disposed on a second side of said first body and second body; and a second metal blade member having (i) a second arm portion, (ii) a second cutting portion defining a second cutting surface, and (iii) a second intermediate portion interposed between said second arm portion and said second cutting portion, wherein said second metal blade member is disposed on said second side of said first body and second body, wherein said first arm portion of said first metal blade member is pivotably connected to said first body of said first metal plate, wherein said second arm portion of said second metal blade member is pivotably connected to said second body of said second metal plate, wherein said first intermediate portion of said first metal blade is pivotably connected to said second intermediate portion of said second metal blade, wherein movement of said first handle with respect to said second handle causes movement of said first cutting portion with respect to said second cutting portion, wherein said movement of said first handle with respect to said second handle causes said first stop to contact said second stop to thereby prevent further movement of said first cutting portion with respect to said cutting portion when in an open position in which said first metal blade member and said second metal blade member are in spaced relation with said first teeth and said second teeth and said first cutting portion and second cutting portion are in spaced relation to each other by a distance sized to receive vegetation to be severed.
