ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a lighter, and more particularly to a lighter having a safety mechanism.
2. Description of the Prior Art
Typical lighters comprise a cap pivotally secured to a housing at a pivot shaft for actuating an ignitor device and a valve device when the cap is rotated about the pivot shaft. No safety device is provided for locking the cap and for preventing the ignitor device from being actuated by the cap inadvertently.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional lighters.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a lighter having a safety mechanism for preventing the cap from being actuated inadvertently by the children.
In accordance with one aspect of the invention, there is provided a lighter comprising a housing including a chamber formed therein for receiving gas fuel therein, and including an ignitor device received therein, the housing including an orifice formed therein for allowing the gas fuel to flow outward of the housing, a cap pivotally secured to the housing at a pivot shaft, the cap including an aperture for aligning with the orifice of the housing, a latch slidably engaged in the aperture of the cap and the orifice of the housing in order to lock the cap to the housing, and means for disengaging the latch from the orifice of the housing in order to release the cap from the housing. The cap is allowed to be rotated about the pivot shaft when the latch is disengaged from the orifice of the housing.
A spring biasing device is further provided for biasing the latch to engage into the orifice of the housing. A guiding device is further provided for guiding the latch to move relative to the cap and includes a block extended in the cap, the latch has a projection slidably engaged with the block of the cap for guiding the latch to move relative to the cap and for preventing the latch from rotating relative to the cap.
The latch includes at least one arm laterally extended outward therefrom, the disengaging means includes a knob slidably received in the cap and having at least one leg extended therefrom for engaging with the arm and for disengaging the latch from the orifice of the housing. The leg includes a tapered end, the arm includes a tapered end for engaging with tapered end of the leg. The cap includes a lid having an opening formed therein for slidably receiving the knob, and for allowing the knob to be moved toward the latch.
A spring biasing device is further provided for biasing the knob away from the latch and includes a spring blade extended from the knob and engaged with the cap for biasing the knob away from the latch. The cap includes a cavity formed therein, the spring blade includes a bulge extended therefrom for engaging with the cavity of the cap and for positioning the spring blade to the cap.
Further objectives and advantages of the present invention will become apparent from a careful reading of a detailed description provided hereinbelow, with appropriate reference to accompanying drawings.
