Abstract
A folding knife is disclosed. The folding knife includes a handle; a blade connected to the handle in a manner allowing pivoting of the blade between a closed position in which the blade extends along the handle, and an open position in which the blade extends away from the handle; and a blade-assisting mechanism including a biasing assembly and a housing, wherein the biasing assembly is configured to urge the blade towards at least one of the open position and the closed position over at least a portion of the blade travel between the closed position and the open position, and the housing encloses at least a portion of the blade-assisting mechanism, and wherein the blade-assisting mechanism is configured to be removably mounted between the blade and the handle.
Claims22
A folding knife, comprising:
- a handle;
- a blade connected to the handle in a manner allowing pivoting of the blade between a closed position in which the blade extends along the handle, and an open position in which the blade extends away from the handle;
- and
- a blade-assisting mechanism including a biasing assembly and a housing, wherein the biasing assembly is configured to urge the blade towards at least one of the open position and the closed position over at least a portion of the blade travel between the closed position and the open position the housing enclosing the biasing assembly;
- and
- a plurality of pivot connectors that pivotally couple the blade-assisting mechanism between the blade and the handle.
A folding knife, comprising:
- a handle having an inner portion and an outer portion;
- a blade connected to the handle in a manner allowing pivoting of the blade between a closed position in which the blade extends along the inner portion of the handle, and an open position in which the blade extends away from the handle;
- and
- a housing;
- a first mounting element configured to pivotally couple the housing to the blade, a second mounting element configured to pivotally couple the housing to the handle;
- and
- a biasing assembly within the housing configured to apply a force between the first and second mounting elements that urges the blade towards at least one of the open position and the closed position over at least a portion of the blade travel between the open position and the closed position.
A folding knife, comprising:
- a handle;
- a blade connected to the handle in a manner allowing pivoting of the blade between a closed position and an open position;
- and
- a blade-assisting mechanism including a first mounting element configured to be removably coupled to the blade, a second mounting element configured to be removably coupled to the handle, and a biasing assembly operatively coupled between the first and second mounting elements to apply a force that urges the blade towards at least one of the open position and the closed position over at least a portion of the blade travel between the open position and the closed position, the blade-assisting mechanism being external to the handle.
A folding knife kit, comprising:
- a folding knife having a handle and a blade, the blade being connected to the handle in a manner allowing movement of the blade between a closed position in which the blade extends along the handle, and an open position in which the blade extends away from the handle, the blade having a recess therein;
- a plurality of housings, each housing having a respective one of a plurality of biasing assemblies enclosed therein and each housing configured to be removably mounted between the handle and the blade, the biasing assembly of each housing being configured to urge the blade towards at least one of the open position and the closed position over at least a portion of the blade travel between the open position and the closed position, each housing having an aperture;
- and
- at least one pivot connector that is sized to extend through the aperture of the housing and into the recess of the blade to pivotally couple the housing to the blade.
