Description
- The present invention is related to a lighter having simple structure and easily operable, and more particularly to an improved safety device installed on a lighter.
- There are various types of safety devices installed on lighters for preventing the lighters from being unexpectedly ignited by children. For example, Taiwanese Patent Application No. 91203578 discloses a fixing bracket of a lighter. Taiwanese Patent Application No. 88102379 discloses a safety device of a lighter. Taiwanese Patent Application No. 85106865 discloses a lighter with protective ring. Taiwanese Patent Application No. 88220694 discloses an improved gas reservoir of a lighter. Taiwanese Patent Application No. 90216111 discloses a childproof safety device of a lighter. Taiwanese Patent Application No. 85200409 discloses a casing of a lighter. Taiwanese Patent Application No. 91208302 discloses a dislocation safety lighter.
- Another conventional safety lighter includes a dog. A user can push the dog with the thumb and disengage the dog from the casing of the lighter. Under such circumstance, the user can press a press key to ignite the lighter. Such structure has some shortcomings. For example, the assembly of the press section and the dog is complicated and the dog must be transversely pushed. When transversely pushing the dog, an operator's thumb must be vertically placed over or in the axis of the lighter. Therefore, it is inconvenient for the operator to transversely push the dog with the thumb.
- Taiwanese Patent Application No. 81216824 discloses a safety lighter with a security bar. The lighter has a press section which can be resiliently moved upward for igniting the lighter. A projecting bar is connected under the press section. A recessed shoulder section is formed between the press section and the projecting bar. A security bar is disposed on a base section of the upper frame near the fuel container. The security bar can be pulled downward. The press section is supported by a restoring spring. The security bar outward transversely extends to connect with an elongated bar and form a latch section for latching with the recessed shoulder section. The projecting bar can be biased to arrest the press section. Such design minimizes the possibility of unexpected ignition of the lighter by children. However, the structure of the lighter is complicated and the manufacturing cost is higher.
- It is therefore tried by the applicant to provide a safety device of a lighter which has simplified structure and can be conveniently operated.
- It is therefore a primary object of the present invention to provide a safety device of a lighter which has simplified structure and can be easily operated. The safety device includes a main body having a fuel reservoir, a base seat, an arrester mounted in the main body, an ignition system controlled by the arrester, a valve member for opening/closing the fuel reservoir and a press section arranged on the base seat and having a suspension arm. The press section is movable and rotatable in a set path for driving the arrester. A stopper block is disposed in the set path for interfering with the rotation of the press section or the suspension arm or preventing the press section or the suspension arm from rotating. The press section is selectively movable to release the suspension arm from the interference of the stopper block, permitting the press section to be turned for ignition.
- It is a further object of the present invention to provide the above safety device of the lighter in which the suspension arm of the press section is formed with a wedge hole and at least one notch. A stake is fitted through the stake hole of the base seat and the wedge hole of the suspension arm for fixing the press section and the suspension arm on the base seat. The stake is movable within the wedge hole of the suspension arm with the press section moving in the set path until the notch of the suspension arm moves to the position of the stopper block. In this position, by means of the notch, the press section can avoid the stopper block and be turned for ignition.

FIG. 6 is a perspective partially sectional view of another embodiment of the present invention. - Please refer to
FIGS. 1, 2 and 3. The safety device of the lighter of the present invention includes amain body 10 having afuel reservoir 11, abase seat 20 disposed at an upperopen end 12 of themain body 10, anarrester 30 mounted in themain body 10, anignition system 40 controlled by thearrester 30 and avalve member 50 for opening/closing thefuel reservoir 11. Thebase seat 20 has a symmetrically extendingbottom section 21 formed with astake hole 22.FIG. 3 shows that aresilient member 70 always forcedly positions anactivation section 31 of thearrester 30 in a home position. - A
press section 60 is arranged on thebase seat 20. Thepress section 60 is movable and rotatable in a set path for driving theactivation section 31 of thearrester 30. Thepress section 60 includes asuspension arm 61 having a linkingsection 63. Thesuspension arm 61 is formed with awedge hole 62. Thesuspension arm 61 is further formed with at least onenotch 64. Referring toFIGS. 2 and 3 , astake 80 is fitted through thestake hole 22 of the base seat and thewedge hole 62 of the suspension arm for fixing thepress section 60 and thesuspension arm 61 on thebase seat 20. A gap x is defined between thepress section 60 and thebase seat 20. Astopper block 23 is formed on thebase seat 20 in the set path of thepress section 60 for interfering with the rotation of thepress section 60 or thesuspension arm 61 or preventing thepress section 60 orsuspension arm 61 from rotating. - In a preferred embodiment, the
stopper block 23 nearly perpendicularly projects from thebottom section 21 of the base seat. Thestake 80 is relatively movable within thewedge hole 62 of thesuspension arm 61 for moving thepress section 60 in the set path until thenotch 64 of the suspension arm moves to the position of thestopper block 23. In this position, by means of thenotch 64, thepress section 60 can avoid thestopper block 23 and be turned. Accordingly, thesuspension arm 61 can be selectively released from the interference of thestopper block 23, permitting thepress section 60 to be turned for ignition. (This will be further described hereinafter.) - Referring to
FIGS. 2 and 3 , thestake hole 22 of thebase seat 20 has the same circular cross-sectional shape of thestake 80. Thewedge hole 62 of the suspension arm has a substantially rectangular or elliptic cross-sectional shape having anupper arc end 65 and alower arc end 66.FIG. 3 shows that the safety device of the lighter is positioned in its home position. Thestake 80 is positioned at thelower arc end 66 of thewedge hole 62 of the suspension arm. Under such circumstance, thestopper block 23 interrupts the rotational path of thesuspension arm 61 so that thepress section 60 cannot be turned. - When an operator presses down the
press section 60, thesuspension arm 61 is moved downward as shown inFIG. 4 . At this time, thestake 80 is relatively moved to theupper arc end 65 of thewedge hole 62 and thenotch 64 of thesuspension arm 64 is moved to the position of thestopper block 23. Under such circumstance, by means of thenotch 64, the interference between thestopper block 23 and thesuspension arm 61 is discharged and thepress section 60 can avoid thestopper block 23 and be turned as shown inFIG. 5 .FIG. 5 also shows that after turned, the linkingsection 63 of thesuspension arm 61 of the press section depresses theactivation section 31 of thearrester 30 to activate theignition system 40 and make thevalve member 50 open thefuel reservoir 11 to release fuel. When the operation force disappears, theresilient member 70 pushes theactivation section 31 back to its home position, whereby thesuspension arm 61 and thepress sect ion 60 are restored to their home position as shown inFIG. 3 . - It should be noted that the gap x between the
press section 60 and thebase seat 20 is approximately equal to the travel of thestake 80 within thewedge hole 62. -
FIG. 6 shows another embodiment of the present invention, in which thestopper block 23 is formed on apillar 13 of upper section of thefuel reservoir 11 still in the set path of thepress section 60 or thesuspension arm 61. - In conclusion, with simplified structure, the safety device of the lighter of the present invention provides a childproof security effect to ensure safety in use of the lighter.
- The above embodiments are only used to illustrate the present invention, not intended to limit the scope thereof. Many modifications of the above embodiments can be made without departing from the spirit of the present invention.
