Abstract
A safety lighter having a safety switch which prevents ignition of the lighter by automatically blocking the activation trigger from returning to a pre-ignition position and in turn prevents the piezoelectric actuator from returning to a pre-ignition position after the activation trigger has been urged to an ignition position. The safety switch has a slanted member having an engagement surface and a sliding surface, and a U-shaped sliding slot member having a resilient pane, a guide arm, a blocking surface, and a safety trigger. The safety switch allows ignition of the lighter only after the safety trigger is urged upward such that the activation trigger and the piezoelectric actuator return to their pre-ignition positions.
Claims14
A safety lighter having a piezoelectric actuator attached to a lighter housing, said piezoelectric actuator positioned adjacent to an activation trigger, said activation trigger slidably attached to said housing, said safety lighter comprising:
- a safety switch slidably attached to said housing and positioned adjacent to said activation trigger, said safety switch having a first slanted member attached to said housing and a sliding slot member positioned adjacent to and movable along said slanted member, said sliding slot member comprising a blocking shoulder capable of engaging said activation trigger to prevent said activation trigger from returning to a first pre-ignition position after urgement of said activation trigger to an ignition trigger position, upon movement of said blocking shoulder in an upward direction, said activation trigger is allowed to return to said pre-ignition position.
A safety lighter having a piezoelectric actuator attached to a lighter housing, said piezoelectric actuator positioned adjacent to an activation trigger, said activation trigger slidably attached to said housing, said safety lighter comprising:
- a safety switch slidably attached to said housing and positioned adjacent to said activation trigger, said safety switch having a first slanted member attached to said housing and a sliding slot member positioned adjacent to and movable along said slanted member, said sliding slot member comprising a blocking shoulder capable of engaging said activation trigger to prevent said activation trigger from returning to a first pre-ignition position after urgement of said activation trigger to an ignition trigger position,
- said sliding slot member movable along said slanted member from a first operational position to a second safety position, while positioned in said second safety position said blocking shoulder of said sliding slot member is capable of blocking said activation trigger from returning to said first pre-ignition position after urgement of said activation trigger to said ignition trigger position, upon movement of said blocking shoulder in an upward direction, said activation trigger is allowed to return to said pre-ignition position.
A safety lighter having a piezoelectric actuator attached to a lighter housing, said piezoelectric actuator positioned adjacent to an activation trigger, said activation trigger slidably attached to said housing, said safety lighter comprising:
- a safety switch slidably attached to said housing and positioned adjacent to said activation trigger, said safety switch having a first slanted member attached to said housing and a sliding slot member positioned adjacent to and movable along said slanted member, said sliding slot member comprising a blocking shoulder capable of engaging said activation trigger to prevent said activation trigger from returning to a first pre-ignition position after urgement of said activation trigger to an ignition trigger position;
- said sliding slot member movable along said slanted member from a first operational position to a second safety position, while positioned in said second safety position, said blocking shoulder of said sliding slot member is capable of blocking said activation trigger from returning to said first pre-ignition position after urgement of said activation trigger to said ignition trigger position, upon movement of said blocking shoulder in an upward direction, said activation trigger is allowed to return to said pre-ignition position.
