Abstract
A hand tool includes a handle assembly, a jaw assembly, a locking assembly, and an adjustment assembly. The handle assembly may include a first handle and a second handle, each of the first and second handles having a proximal end and a distal end. The jaw assembly may include a first jaw and a second jaw. The first jaw may be attached to the proximal end the second handle via a transition region comprising an adjustment channel. The locking assembly may be configured to enable the first and second jaws to be locked at a selected distance from each other in a locked state. The adjustment assembly may include the adjustment channel and a bite adjustment member configured to enable the selected distance to be modified in an unlocked state based on a position of the bite adjustment member in the adjustment channel.
Claims19
A hand tool comprising:
- a handle assembly comprising a first handle and a second handle, each of the first and second handles having a proximal end and a distal end;
- a jaw assembly comprising a first jaw and a second jaw, the first jaw being attached to the proximal end of the second handle via a transition region comprising an adjustment channel;
- a locking assembly configured to enable the first and second jaws to be locked at a selected distance from each other in a locked state;
- and
- an adjustment assembly comprising the adjustment channel and a bite adjustment member configured to enable the selected distance to be modified in an unlocked state based on a position of the bite adjustment member in the adjustment channel,
- wherein the second jaw is pivotally connected to a pivot connector via a first pivot link, the pivot connector being further pivotally connected to the first handle via a second pivot link,
- wherein the pivot connector is repositioned between a first position and a second position based on a position of the first handle relative to the second handle to alternately transition the hand tool between the locked state and the unlocked state, respectively, and
- wherein the hand tool enters the locked state responsive to the first and second handles being pivoted towards each other and the hand tool enters the unlocked state responsive to the first and second handles being pivoted away from each other.
A hand tool comprising:
- a handle assembly comprising a first handle and a second handle, each of the first and second handles having a proximal end and a distal end;
- a jaw assembly comprising a first jaw and a second jaw, the first jaw being attached to the proximal end the second handle via a transition region comprising an adjustment channel;
- a locking assembly configured to enable the first and second jaws to be locked at a selected distance from each other in a locked state;
- and
- an adjustment assembly comprising the adjustment channel and a bite adjustment member configured to enable the selected distance to be modified in an unlocked state based on a position of the bite adjustment member in the adjustment channel,
- wherein the adjustment channel comprises a fixing array and the bite adjustment member comprises an engaging array configured to selectively interface with the fixing array based on a position of the first handle relative to the second handle,
- wherein the engaging array extends over less than half a length of the bite adjustment member,
- wherein the engaging array comprises teeth configured to engage with teeth of the fixing array, and
- wherein the teeth of the engaging array increase in depth as proximity to an end of the bite adjustment member decreases.
A clamping assembly for locking an adjustable locking pliers having a handle assembly comprising a first handle and a second handle and a jaw assembly comprising a first jaw and a second jaw, the clamping assembly comprising:
- a locking assembly configured to enable the first and second jaws to be locked at a selected distance from each other in a locked state;
- and
- an adjustment assembly comprising an adjustment channel and a bite adjustment member configured to enable the selected distance to be modified in an unlocked state based on a position of the bite adjustment member in the adjustment channel,
- wherein the second jaw is pivotally connected to a pivot connector via a first pivot link, the pivot connector being further pivotally connected to the first handle via a second pivot link,
- wherein the pivot connector is repositioned between a first position and a second position based on a position of the first handle relative to the second handle to alternately transition the locking assembly between the locked state and the unlocked state, respectively, and
- wherein the locking assembly enters the locked state responsive to the first and second handles being pivoted towards each other and the locking assembly enters the unlocked state responsive to the first and second handles being pivoted away from each other.
