Abstract
A hand tool for cutting, such as a pair of pruners, includes a pair of opposed elongated members, each member comprising a jaw at a front end portion thereof, a handle at a rear end portion thereof, and a midportion where the members cross over each other. A pivotable joint unites the midportions for scissor-like movement of the handles and jaws, and a spring biases the handles and jaws to an open position. According to the invention, one of the handles is rotatable. A transmission mechanism is provided to interconvert the rotation force applied to the rotatable handle into a rectilinear force used to draw the handles together.
Claims26
A pivoted hand tool having a longitudinal axis, the tool comprising:
- a pair of first and second opposed elongated members, each member having a jaw at a front end portion thereof, a handle at a rear portion thereof, and a midportion where the members cross over each other;
- a pivot uniting the midportions of the elongated members for scissor-like movement of the handles and the jaws about the pivot, the handle of the first elongated member being rotatable about a rotation axis substantially parallel to the longitudinal axis when the jaws are closed;
- and
- a transmission means for interconverting a rotation force applied to the first handle into a rectilinear force drawing the handles closer to each other.
A pivoted hand tool having a longitudinal axis, the tool comprising:
- a pair of first and second opposed elongated members, each member having a jaw at a front end portion thereof, a handle at a rear portion thereof, and a midportion where the members cross over each other;
- a pivot uniting the midportions of the opposed elongated members for scissor-like movement of the handles and the jaws about the pivot;
- and
- wherein the handle of the first elongated member has a center point and is rotatable about a rotation axis substantially parallel to the longitudinal axis when the jaws are closed, the rotation axis being offset from the center point, the handle of the first member being movably connected to a region of the second handle so that a rotation force applied to the first handle produces a rectilinear force drawing the handles closer to each other.
A pivoted hand tool, comprising
- first and a second elongated members each being provided with a jaw at a front end, a handle at a rear end, and a midportion where the members intersect;
- a pivot which connects the midportions of the members to each other in order to allow scissor-like movement of the jaws and handles around the pivot, wherein the handle of the first elongated member, against which the user's fingertips are intended to be placed, is rotatable around a pivot pin in the first elongated member, the pin extending in a direction substantially perpendicular to the pivot;
- and
- a transmission mechanism provided on the rotatable handle and the second elongated member for converting the rotation force of the rotatable handle into a force for drawing the handles closer to each other.
