Abstract
Trigger activated tools are provided that have one or more activation lockouts. The activation lockouts include electrical resets, variable position lockouts, mechanical lockouts, shield lockouts, and any combinations thereof.
Claims17
A trigger activated tool, comprising:
- an activatable device;
- an activation trigger depending from a handle portion for movement about a first axis between a first position and a second position, the activation trigger being configured to activate the activateable device in the second position;
- a lockout depending from the activation trigger for movement about a second axis between a locked state and an unlocked state, the locked state preventing activation of the activatable device by the activation trigger;
- and
- a drain trigger depending from the handle portion for movement about the first axis, the drain trigger being configured to relieve potential energy within the activatable device when the lockout is in both the locked and unlocked states, the drain trigger being configured to relieve potential energy within the activatable device when the activation trigger is in the first position, but not the second position, wherein the first and second axes are offset from one another.
2 more elements
A trigger activated tool, comprising:
- a jaw;
- a power source;
- a hydraulic unit operatively connected with the jaw;
- a handle portion having an activation trigger and a drain trigger both depending from a common pivot axis;
- and
- a trigger lock rotatably secured in the activation trigger for rotation about a second axis, the second axis being offset from the common pivot axis,
- the activation trigger being configured to move about the common pivot axis between a normal position and an activated position, the activation trigger, when in the activated position, placing the hydraulic unit in electrical communication with the power source such that the hydraulic unit activates the jaw,
- the drain trigger being configured to move about the common pivot axis between a normal position and a drain position, the drain trigger, when in the drain position, relieving potential energy within the hydraulic unit, and
- the trigger lock being configured to move between a normal position and an activation position,
- wherein the activation trigger, the drain trigger, and the trigger lock each being biased to the normal positions, respectively,
- wherein the trigger lock, when in the normal position, providing a mechanical interference to prevent movement of the activation trigger to the activated position and, when in the activation position, allowing movement of the activation trigger to the activated position, and
- wherein the drain trigger is configured to move between the normal position and the drain position when the trigger lock is in both the normal and activation positions.
9 more elements
A trigger activated tool, comprising:
- an activatable device defining a first pivot axis;
- an activation trigger depending from the first pivot axis for movement between a first position and a second position, the activation trigger being configured to activate the activateable device in the second position;
- a drain trigger depending from the first pivot axis for movement between a normal position and a drain position, the drain trigger being configured to relieve potential energy within the activatable device in the drain position;
- and
- a lockout rotatably secured in the activation trigger for rotation about a second axis between a locked position and an unlocked position, the locked position preventing movement of the activation trigger from the first position and the unlocked position allowing movement of the activation trigger from the first position, wherein the drain trigger can move between the normal and drain positions regardless whether the lockout is in the locked position or the unlocked position, wherein the first axis is offset from the second axis.
