Abstract
A folding knife having a blade pivot connecting a blade to a handle for pivotal movement between an extended position outside of the blade cavity and a retracted position substantially within the blade cavity. A spring biased plunger having a first end and second end opposite the first end is provided, and the first end of the plunger includes a pivotal connector pivotally connecting the plunger to the handle within the blade cavity. The second end of the plunger is pivotally connected to the blade for orbital movement about the blade pivot as the blade moves between the retracted and extended positions. A pivotable locking member is connected to the handle for selectively locking the blade in the extended position. Further, an engagement portion is provided for opening the blade using a downward motion.
Claims11
A folding knife, comprising:
- a handle defining a blade cavity and a first end;
- a blade having a first end and a second end opposite said first end;
- said first end of said blade having a blade pivot connected to said first end of said handle for pivotal movement of said blade about said blade pivot between an extended position wherein the blade is outside of said blade cavity and a retracted position wherein the blade is substantially within said blade cavity;
- a longitudinally extending plunger carried in said blade cavity having a first end and second end opposite said first end;
- a pivotal connector pivotally connected to said handle for pivotally connecting said plunger to said handle, said first end of said plunger being longitudinally slidably carried by said pivotal connector for longitudinal movement of said plunger relative to said pivotal connector as said blade moves between said retracted and extended positions;
- and
- said second end of said plunger being pivotally connected to said first end of said blade for orbital movement about said blade pivot as said blade moves between said retracted and extended positions.
A folding knife, comprising:

- a blade having a first end and a second end opposite said first end;
- said first end of said blade having a blade pivot connected to said first end of said handle for pivotal movement of said blade about said blade pivot between an extended position wherein the blade is outside of said blade cavity and a retracted position wherein the blade is substantially within said blade cavity;
- a spring longitudinally extending plunger carried in said blade cavity having a first end and second end opposite said first end;
- a sleeve provided in said handle, said sleeve receiving and longitudinally slidably carrying said first end of said plunger for longitudinal movement of said plunger relative to said sleeve as said blade moves between said retracted and extended positions;
- and
- said second end of said plunger being pivotally connected to said first end of said blade for orbital movement about said blade pivot as said blade moves between said retracted and extended positions.
