Abstract
A folding knife having a blade pivotally connected to an end of a handle so that the blade is rotatable about a pivot axis between an open position and a closed position. In the open position, the blade is extended away from the handle. In the closed position, the blade is at least partially received within the handle. The knife also has a locking mechanism that is movably secured to the handle so that it may be moved into a locking position. When in the locking position, the locking mechanism blocks a protruding member extending transversely outward from a surface of the blade to prevent the blade from being rotated from the open position to the closed position.
Claims32
A folding knife comprising:
- a handle having a pivot shaft;
- a blade movably secured to the handle so that the blade is rotatable about the pivot shaft between a closed position and an open position;
- a post located on the blade, where the post moves along a path of travel when the blade is rotated about the pivot shaft;
- and
- a movable latch, where, when the blade is in the open position, the latch is movable into an extended position in which it extends into the path of travel of the post, to prevent the blade from moving from the open position toward the closed position.
A folding knife, comprising:
- a blade pivotally connected to an end of a handle so that the blade is rotatable about a pivot axis between an open position in which the blade is extended away from the handle and a closed position in which the blade is at least partially received within the handle;
- and
- a locking mechanism secured to the handle and movable into a locking position in which the locking mechanism blocks a protruding member extending outward from a surface of the blade to prevent the blade from being rotated from the open position to the closed position.
A folding knife comprising:
- a handle;
- a blade pivotably secured to an end of the handle with a pintle so that the blade is pivotable between a closed position in which the blade is received at least partially within the handle and an open position in which the blade extends away from the handle;
- a post located on the blade adjacent the pintle;
- and
- a latch movably secured to the handle, where:
- the post and latch are configured so that the post pushes the latch into a retracted position as the blade rotates from the closed position to the open position and permits the latch to return to a locking position when the blade is fully rotated to the open position;
- and
- the latch is biased into the locking position, in which the latch interacts with the post to lock the blade in the open position.
