Pressure washer trigger lock

A pressure washer wand connectable to a source of fluid, the pressure washer wand comprising:

• a housing defining an interior;
• a flow path within the interior and including an inlet in fluid communication with the source and an outlet;
• a valve having a valve member in the flow path that is movable between a closed position and an open position in which fluid travels from the inlet to the outlet;
• a user interface movable between an actuated position in which the valve is open and a non-actuated position in which the valve is closed;
• and
• a lock member movable in a first direction from a locked position to a first unlocked position and movable in a second direction opposite the first direction from the locked position to a second unlocked position, the lock member inhibiting movement of the user interface to the actuated position when in either of the first locked position and the second locked position.

A pressure washer wand connectable to a source of fluid, the pressure washer wand comprising:

• a housing defining a guard having a front portion and a rear portion;
• a flow path disposed substantially within the housing and including an inlet in fluid communication with the source and an outlet;
• a valve having a valve member in the flow path that is movable between a closed position and an open position in which fluid travels from the inlet to the outlet;
• a user interface movable between an actuated position in which the valve is open and a non-actuated position in which the valve is closed, the user interface being movable toward the rear portion when moving toward the actuated position;
• a lock member substantially disposed between the user interface and the rear portion and movable from a locked position toward the user interface to an unlocked position, such that when in the locked position, the lock assembly inhibits movement of the user interface to the actuated position;
• and
• a biasing member that biases the lock member toward the locked position.

A method of operating a pressure washer wand defining a first side, a second side, a user interface, an inlet, an outlet, and a locking assembly, the method comprising:

• providing a flow of fluid to the inlet;
• inhibiting flow from the inlet to the outlet;
• moving the user interface from a non-actuated position toward an actuated position;
• inhibiting movement of the user interface to the actuated position;
• moving the lock assembly from a locked position to an unlocked position to allow movement of the user interface to the actuated position;
• releasing the user interface;
• and
• biasing the user interface to the non-actuated position and the lock assembly to the locked position.
