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 lock device.
2. Description of the Prior Art
Typical lighters, such as the cigarette lighters are widely used and may be easily available everywhere. U.S. Pat. No. 5,713,733 to Ming discloses one of the typical cigarette lighters. The typical cigarette lighters have no lock devices or have no safety mechanisms for preventing the typical cigarette lighters from being easily operated by the children 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 lock device for locking the lighter and for preventing the lighter from being operated by children inadvertently.
In accordance with one aspect of the invention, there is provided a lighter comprising a container including a chamber formed therein for receiving gas therein, the container including an upper portion, an igniting device secured in the container and including a button to be depressed relative to the container for igniting purposes, a block slidably received in the container, a cap engaged on the upper portion of the container and pivotally secured to the block with a pivot shaft, an actuator secured to the slide and moved in concert with the block relative to the container and engaged with the button for depressing the button to ignite the lighter, and a latching means for latching the actuator to the cap and to prevent the cap from being rotated relative to the block about the pivot shaft and to prevent the actuator from being depressed inward of the container inadvertently by the children.
The block is slidable inward and outward of the container, the cap includes at least one leg extended therefrom and extended inward of the container and pivotally secured to the container with the pivot shaft. A device may further be provided for guiding the block to move inward and outward relative to the container.
The actuator includes a stop extended inward thereof for engaging with the button and for depressing the button when the actuator is depressed inward of the container. The actuator includes at least one pin extended therefrom and engaged into the block for securing the actuator to the slide.
The latching means includes a latch slidably received in the actuator and movable toward to the cap to engage with the cap, and includes a biasing means for biasing the latch toward the cap to engage with the cap and to prevent the cap from being rotated relative to the block about the pivot shaft.
The latch includes at least one groove formed therein, the actuator includes a channel formed therein for slidably receiving the latch, and includes at least one rail extended inward of the channel of the actuator and extended and slidably engaged in the groove of the latch to guide the latch to move toward and away from the cap.
The cap includes an extension extended therefrom and includes a head provided on said extension for engaging with the latch. The latch may include an ear extended therefrom for engaging with the extension of the cap and for preventing the cap from being rotated relative to the block about the pivot shaft.
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.
