Description
- 1. Field of the Invention
- The invention relates to a children resistant gas lighter, and more particularly, to a gas lighter which is more credible in preventing unintentional ignition.
- 2. Description of the Prior Art
- The lighter industry has been engaging for developing a simple yet credible children resistant device for prevent the lighter from unintentional ignition.
- Such a lighter is diclosed in U.S. Pat. No. 5,839,892 named “Electronic Lighter with A Safety Device”. The lighter has a press button means consists of an upper cover and “the upper cover has two hook-like ends of the press cylinder such that the hook-like ends of the upper cover are retained by a step portioin near an upper end of each second guide slot when the lighter is not in use.”
- The lighter of the aforementioned patent has a drawback. A user who does not know how to use the lighter very possibly may increase a pressing force to ignite the lighter while he cannot ignite it with ordenary force as use with conventional gas lighter. However the structure of safety of the two hool-like ends is too thin to withstand the greater force. In fact, either one of the two hook-like ends or both often breaks in actual use when an unkown user forcibly press the upper cover down, which would invalidate the safety device. It means the credibility of the safety device is not very satisfactory.
- The object of the invention is to provide a children resistant gas lighter having a more credible safety device.
- The other object of the invention is to provide a children resistant gas ligher which is hard for children to get undersand how to ignition thus making it safer for children.
- In order to accomplish the aforementioned objects, the present invention provides a children resistant gas lighter having a fuel-storage chamber for containing liquefied gaseous fuel; an upliftable gas release nozzle mounted on the fuel-storage chamber; a piezoelectric unit mounted on the fuel-storage chamber and having a piezoelectric button which when pressed downward, is able to startup the piezoelectric unit to generate sparks for ignition; a pair of pillars securely mounted on the fuel-storage chamber; an ignition trigger having a ignition sleeve slidably mounted on the pair of pillars which when pressed down, slidable with respect to the pair of pillars and when released, resumable to its undepressed position; a lever rotatably mounted on the fuel-storage chamber which when the ignition trigger is pressed down, is able to uplift the gas release nozzle to release the gaseous fuel and at the same time depress the piezoelectric button to startup the piezoelectric unit to generate sparks; a slit defined in the ignition sleeve; a flame cover having a top surface and being installed on the fuel-storage chamber and fixed to the pair of pillars; and, a safe cap having a press surface, an opposite slide surface, a direction bar formed on the slide surface which is insterted in the slit and is able to make the safe cap slidable in the slit, a pair of stoppers formed on the direction bar which is able to provent falling off of the safe cap with respect to the ignition sleeve when sliding, a pole formed on the direction bar, a bias spring installed on the pole biasing the safe cap with respect to the ignition sleeve, and, a shoulder near the first end of the safe cap.
- These and other objectives, features, and advantages of the present invention will become apparent from the following detailed description, the accompanying drawings, and the appended claims.
-
FIG. 1 is a perspective view of the preferred embodiment of the children resistant gas lighter of the invention. -
FIG. 2 is an exploded perspective view of the children resistant gas lighter of the inventoin shown inFIG. 1 . -

FIG. 4 is a bottom view of the safe cap of the invention shown inFIG. 1 . -
FIG. 5 is a side view of an ignition sleeve of the invention shown inFIG. 1 . And, -
FIG. 6 is an exploded perspective view of another preferred embodiment of the invention. - With reference to
FIGS. 1 and 2 , the children resistant lighter of the invention has a fuel-storage chamber 10 for containing liquefied gaseous fuel, an upliftablegas release nozzle 20 mounted on the fuel-storage chamber 10, a piezoelectric unit 30 securely mounted on the fuel-storage chamber 10 and having apiezoelectric button 31 which when pressed downward, is able to startup the piezoelectric unit 30 to generate sparks for ignition, a pair ofpillars 11 securely mounted on the fuel-storage chamber 10, anignition trigger 40 having anignition sleeve 41 slidably mounted on thepillars 11 which when pressed down, slidable with respect to thepillars 11 and when released, resumable to its undepressed position, alever 50 rotatably mounted on the fuel-storage chamber 10 which when theignition trigger module 40 is pressed down, is able to uplift thegas release nozzle 20 to release the gaseous fuel and at the same time depress thepiezoelectric button 31 to startup the piezoelectric unit 30 to generate sparks, and, aflame cover 60 having atop surface 61 and being installed on the fuel-storage chamber 10 and fixed to the pair ofpillars 11. Thegas release nozzle 20 is so positioned that the gaseous fuel being released is easy able to be ignited by the sparks generated from the piezoelectric unit 30. - As shown in
FIGS. 3 and 4 , aslit 411 is defined in theignition sleeve 41. theslit 411 has anopen end 412 and aclose end 413. Theignition trigger 40 further has asafe cap 42 having apress surface 421 and anopposite slide surface 422. Thesafe cap 42 has adirection bar 423 formed on theslide surface 422 thereof. Thedirection bar 423 has afirst end 424 close to thegas release nozzle 20 and asecond end 425 in opposite. Thesecond end 425 of thedirection bar 423 is able to be inserted into theopen end 412 ofslit 411 thus making thedirection bar 423 slidable in theslit 411. A pair ofstoppers 426 may be formed on thedirection bar 421 near thefirst end 424 thereof which is able to provent falling off of thesafe cap 42 with respect to theignition sleeve 41 when sliding. Apole 427 is formed on thedirection bar 42 on which abias spring 428 is installed. Thesafe cap 42 also has ashoulder 420 near thefirst end 424 thereof. In assembly, thesecond end 425 of thedirection bar 423 is first inserted into theopen end 412 ofslit 411. And then theignition buttom 41 is inserted into the fuel-storage chamber 10. Then thesafe cap 42 is moved by thumb in a direction from theopen end 412 of theslit 411 to theclose end 413 until theflame cover 60 can be attached to the fuel-storage chamber 10 and the pair ofpillars 11. Then thesafe cap 42 can be released and it will slide along theslit 411 until theshouder 420 of thesafe cap 42 stops just on thetop surface 61 of theflame cover 60. - In use, as with reference back to
FIG. 1 , an action of pressing thesafe cap 42 directly downward cannot ignite the lighter because theshoulder 420 of thesafe cap 42 is blocked by thetop surface 61 of theflame cover 60. In order to ignite the lighter, a user has to move thesafe cap 42 against thebias spring 428 by his thumb and then press down thesafe cap 42 when thesafe cap 42 is no longer blocked by thetop surface 61 of theflame cover 60. After ignition, the user may release thesafe cap 42. Theignition buttom 41 slides back and thesafe cap 42 then resumes its original position before moved under a biasing force from thebias spring 428. - The lighter of the invention may have a housing (not shown in the FIGs.) for containing the fuel-
storage chamber 10. As shown in FIGs., thepress surface 421 of thesafe cap 42 may have a raisedwale 429 for antislipping when moved by thumb. -
FIG. 6 shows another embodiment of the invention. In this embodiment, theflame cover 60′ has arecess 62′ for receiving theshoulder 420′ of thesafe cap 42′, making thetop surface 61′ of theflame cover 60′ be at a same level as a top surface of thesafe cap 42′. - The embodiments of the present invention as shown in the drawings and described above is exemplary only and not intended to be limiting.
- From above description, it is seen that the objects of the present invention have been fully and effectively accomplished. Embodiment of the inventioin has been shown and described for the purposes of illustrating the functional and structural principles of the present invention and is subject to change without departure from the invention's principles. Therefore, this invention includes all modifications encompassed within the spirit and scope of the following claims.
