Abstract
A trigger locking system for a liquid applicator having a trigger with an opening is provided. The trigger locking system comprises trigger locking device configured to extend through the opening. The trigger locking device is configured to move, when actuated, between a defined locked position and a defined unlocked position. While the system is in a locked position, the trigger is nonactuable. While the system is in an unlocked position, the trigger is actuable such that, when actuated, a liquid is released from the liquid applicator.
Claims15
A trigger locking system for a liquid applicator having a trigger with an opening, the trigger locking system comprising:
- a trigger locking device configured to extend through the opening, wherein the trigger locking device is configured to move, when actuated, between a locked position and an unlocked position;
- wherein, in the locked position, the trigger is nonactuable;
- wherein, in the unlocked position, the trigger is actuable such that, when actuated, a liquid is released from the liquid applicator;
- and
- wherein the trigger locking device is configured to receive a locking mechanism, wherein the locking mechanism is configured to engage a first position or a second position on the trigger locking device, wherein the first position comprises the trigger locking device in the locked position, and wherein the second position comprises the trigger locking device in the unlocked position, and wherein the first position and the second position each comprise an indentation.
An applicator configured to apply a fluid, comprising:
- a fluid path extending from an inlet of the applicator to an outlet of the applicator;
- a trigger configured to, when actuated, allow the fluid to flow through entirety full length of the fluid path;
- a trigger locking device configured to move between a locked position and an unlocked position, wherein the locked position comprises the trigger locking device positioned such that the trigger locking device substantially inhibits actuation of the trigger;
- and
- a locking mechanism configured to maintain the trigger locking device in either the locked position or the unlocked position, and wherein the locking mechanism comprises a ball and spring configuration, wherein the spring is configured to provide a biasing force against the ball, such that the ball engages an indent of the trigger locking device.
A method for locking and unlocking a paint applicator, comprising:
- receiving, at a fluid inlet of a paint applicator, a source of paint;
- actuating a trigger locking device, such that the trigger locking device, when actuated, moves from a locked position to an unlocked position, wherein, in the locked position, the source of paint is blocked from moving to a fluid outlet of the paint applicator, wherein the trigger locking device comprises a ball and spring configuration such that the spring is configured to provide a biasing force against the ball, such that the ball engages an indent of the trigger locking device, and wherein actuating the trigger locking device comprises application of sufficient pressure to an edge of the trigger locking device to force the ball to disengage from a first indent and reengage to a second indent of the trigger locking device;
- and
- actuating a trigger of the paint applicator such that the source of paint moves from the fluid inlet to the fluid outlet.
