Abstract
A two-lever implement, such as shears, is provided. The implement includes a first lever having a first handle fixed thereon and a second lever pivotally connected to the first lever. The second lever has a second handle which includes a fixed core having an axis and a rotatable outer member disposed about and coaxial with the fixed core and rotatable to and from an at-rest position about the axis. The implement also includes resilient structure carried by the second lever for biasing the outer member back to the at-rest position after the outer member has been moved from the at-rest position.
Claims16
A two lever implement comprising:
- a first lever having a fixed first handle;
- a second lever pivotally connected to the first lever and having a second handle including a fixed core having an axis and a rotatable outer member having a continuous interior surface, the outer member disposed about and coaxial with the fixed core and rotatable about the axis to and from an at-rest position;
- and a resilient structure completely disposed within the continuous interior surface and carried by the second lever for rotationally biasing the outer member back to the at-rest position after the outer member has been rotated from the at-rest position, whereby when the outer member is in the at-rest position, the resilient structure exerts substantially no biasing force on the outer member.
Shears comprising:
- a first lever having a first blade and a fixed first handle;
- a second lever pivotally connected to the first lever and having a second blade and a second handle including a fixed core having an axis and a rotatable outer member having a continuous interior surface, the outer member disposed about and coaxial with the fixed core and rotatable about the axis to and from an at-rest position;
- and resilient structure completely disposed within the continuous interior surface and carried by the second lever for rotationally biasing the outer member back to the at-rest position after the outer member has been rotated from the at-rest position, whereby when the outer member is in the at-rest position, the resilient structure exerts substantially no biasing force on the outer member.
A two lever implement comprising:
- a first lever having a fixed first handle;
- a second lever pivotally connected to the first lever and having a second handle including a fixed core having an axis and an exterior surface and a rotatable outer member disposed about and coaxial with the fixed core and rotatable about the axis to and from an at-rest position, the outer member having an interior surface facing the exterior surface, the interior surface including a radial shoulder structure including first and second walls;
- and a resilient structure carried by the second lever for rotationally biasing the outer member back to the at-rest position after the outer member has been rotated from the at-rest position, whereby when the rotatable outer member is rotated out of the at-rest position in a first direction, the first wall of the radial shoulder structure contacts and deflects a portion of the resilient structure biasing the rotatable outer member back to the at-rest position, whereby when the rotatable outer member is rotated out of the at-rest position in a second direction, the second wall of the radial shoulder structure contacts and deflects a portion of the resilient structure biasing the rotatable outer member back to the at-rest position, whereby when the outer member is in the at-rest position, the resilient structure exerts substantially no biasing force on the outer member.
