Abstract
Description
- This invention relates to a lighter provided with an igniter comprising a flint and a file wheel and a cap for closing the tip of the wick, and more particularly to a structure for opening and closing the cap.
- There has been known a lighter in which liquefied fuel gas or fuel liquid such as alcohol is used and a cap which is pivoted on the lighter to body to open and close the lighter.
- As a mechanism for opening and closing the cap, there has been known that in which the cap is pivoted coaxially with the pivot of a file wheel as disclosed, for instance, in Japanese Unexamined Patent Publication No. 53(1978)-83872.
- However, such a lighter is disadvantageous in that since the cap cannot be wide opened, the tip of the cap apt to be heated by the flame, which is obstructive to closure of the cap, and since the cap is too close to the flame, the cap interferes with lighting a cigarette.
- Further, opening and closing the cap is relatively easy in a lighter where the cap opens and closes the whole upper portion of the lighter including the file wheel, whereas the cap is hard to open in a lighter where the cap only closes a part of the upper portion of the lighter including the burner.
- Further if the cap opening action is not interlocked with the igniting action, the lighter must be ignited in two steps, which is troublesome.
- Further, in a lighter in which liquid fuel is employed, the fuel can be evaporated and consumed when the cap is opened during storage or the like, and accordingly, it is preferred that the cap can be locked in the closed state.
- In view of the foregoing observations and description, the primary object of the present invention is to provide a lighter in which the cap can be wide opened not to be heated by the flame and the cap can be opened without directly touching the cap and locked in the closed state.
- In accordance with the present invention, there is provided a lighter comprising a fuel reservoir in which fuel is stored, a burner member for burning the fuel, an igniter means including a file wheel provided with side wheels and a flint which is caused to strike the file wheel from below, a support post which supports the rotary shaft of the file wheel, and a cap which opens and closes the tip of the burner member, wherein the improvement comprises that
the cap is supported for rotation on a support shaft at its end remote from the file wheel, is urged toward its opening position by a spring and is provided on its end near to the file wheel with a stopper portion which is adapted to be engaged with the rotary shaft of the file wheel, and
the rotary shaft is mounted on the support post to be movable between its locking position where it is engaged with the stopper member to keep the cap in the closed position and its releasing position where it is disengaged from the stopper portion to permit the cap to be opened under the force of the spring so that the rotary shaft is moved to the locking position when the cap is closed and the stopper portion is brought into abutment against the rotary shaft and to the releasing position when the side wheels are operated to ignite the fuel on the burner member. - It is preferred that the side wheels be pushed and rotated to ignite the fuel on the burner member and the rotary shaft be moved to the releasing position in response to the igniting action of the side wheels.
- It is preferred that the rotary shaft of the file wheel be supported in an inclined groove formed on the support post to be inclined rearward downward so that the rotary shaft is moved downward and away from the cap along the inclined groove from the locking position to the releasing position when the side wheels are pushed down and rotated to ignite the fuel on the burner member and so that, when the cap is closed, the rotary shaft is once moved from the locking position to the releasing position pushed by the stopper portion and then moved to the locking position where it is engaged with the upper side of the stopper portion to prevent the cap from being opened.
- It is preferred that the rotary shaft be moved from the releasing position to the locking position under the force of a flint urging spring which presses the flint against the file wheel.
- It is preferred that the fuel be fuel liquid and the burner member be a wick which sucks up the fuel liquid in the reservoir and burns the fuel liquid on its tip.
- In the lighter of the present invention, since the cap is rotated to the opening position on a pivot disposed on the side of the flame opposite to the file wheel, the cap can be wide opened and be remote from the flame, whereby the cap cannot be heated to a high temperature and can be closed by a finger without any trouble. Further, since the cap is locked in the closed position by engagement between the stopper portion on the cap and the rotary shaft of the file wheel, the cap can be surely kept closed, whereby the problem that the cap is accidentally opened during storage or the like and the fuel is evaporated can be avoided. Further since the cap is opened by operation of the side wheels, opening of the cap is facilitated even if the cap is small.
- When the side wheels are pushed and rotated to ignite the fuel on the burner member and the rotary shaft is moved to the releasing position in response to the igniting action of the side wheels, the lighter can be handled very easily.

Theflint holder portion 42 extends upward higher than the upper end of theperipheral wall 4b and downward to the lower end of thejoint wall portion 4c. A flint 11 and aflint urging spring 12, which are components of the igniter means 10, are contained in theflint holder portion 42. - The
aforesaid bracket 5 is formed of a metal plate and is mounted on the top of the reservoirupper lid 4. Thebracket 5 includes aflat plate portion 5a, and afirst window 5b, through which theburner holding portion 41 extends upward, is formed in theflat plate portion 5a. A pair ofsupport posts 51 are erected from theflat plate portion 5a at a rear portion thereof laterally spaced from each other. Eachsupport post 51 is provided with aninclined groove 52 for supporting for rotation a pivot of afile wheel 13 of the igniter means 10. A pair of bearingportions 53 for supporting for rotation thecap 7 are erected from theflat plate portion 5a at a front portion thereof laterally spaced from each other. Further, asecond window 5c, through which theflint holder portion 42 extends upward, is formed in theflat plate portion 5a between thesupport posts 51. - A
side wheels 14 are fixed to opposite sides of thefile wheel 13 of the igniter means 10 so that thefile wheel 13 is rotated together with theside wheels 14. Theside wheels 14 are provided with serration on their outer peripheral surfaces and are rotated when the lighter 1 is to be ignited. Opposite end portions of arotary shaft 15 project outward from the left andright side wheels 14 and are supported for rotation on thesupport posts 51. The flint 11 contained in theflint holder portion 42 is pressed against the surface of thefile wheel 13 under the force of thespring 13 and sparks are thrown toward theburner member 6 in response to rotation of theside wheels 14. - The
aforesaid cap 7 covers a front half of the upper part of the lighter 1 except the igniter means 10, and aninner cap 71 for closing the tip of theburner member 6 is mounted inside thecap 7. Thecap 7 is supported for rotation on the bearingportions 53 by way ofsupport shaft 75 at its front end remote from thefile wheel 13, and is urged toward its opening position by aspring 76. That is, thecap 7 is provided with a pair of mountingportions 72 on opposite sides of the front end portion thereof, and thesupport shaft 75 extends through themounting portions 72 with its opposite end portions supported for rotation on the bearingportions 53. Thespring 76 is in the form of a torsion spring and is mounted on thesupport shaft 75 with its one end in abutment against the inner side of thecap 7 and its the other end in abutment against theflat plate portion 5a of thebracket 5, whereby thecap 7 is urged toward its opening position. - The lower peripheral edge of the
inner cap 71 is pressed against the upper surface of anannular member 21 fitted on theburner holding portion 41 on theupper lid 4 to close in an air-tight fashion the tip of theburner holding portion 41 together with the tip of theburner member 6. - A pair of
extensions 73 extend rearward from the rear end of thecap 7 on opposite sides of thesupport posts 51 and a pair ofstopper portions 74 are provided on the rear ends of therespective extensions 73. Each of thestopper portions 74 has a tip positioned between a pair of inclined surfaces, and the tip is adapted to be engaged with the end portion of therotary shaft 15 projecting outward from theinclined groove 52 of thesupport post 51. - The
rotary shaft 15 is supported in theinclined grooves 52 of thesupport posts 51 to be movable between a locking position and a releasing position. Theinclined grooves 52 are higher on the side near thecap 7 than on the side remote from thecap 7. In the locking position, therotary shaft 15 is held in the upper front portions of theinclined grooves 52 as shown in Figure 1 and in the releasing position, therotary shaft 15 is held lower rear portions of theinclined grooves 52 as shown in Figure 3. The flint 11 is centered with respect to thefile wheel 13 when therotary shaft 15 is in the releasing position. - The
rotary shaft 15 is urged upward by theflint urging spring 12 and normally held in the locking position. When thecap 7 is closed, therotary shaft 15 is first brought into abutment against the lower inclined surface of thestopper portion 74 to be pushed toward the releasing position, and when thecap 7 is fully closed, therotary shaft 15 slides on the upper inclined surface of thestopper portion 74 to the locking position to keep thecap 7 closed. In this state, when theside wheels 14 are rotated in the clockwise direction to ignite the lighter 1, therotary shaft 15 is moved to the releasing position and thestopper portions 74 are disengaged from therotary shaft 15, whereby thecap 7 is opened in response to the igniting action. - Operation of the lighter 1 of this embodiment will be described with reference to Figures 3 to 7, hereinbelow. When the lighter 1 is not being used, e.g., is being stored, the lighter 1 is in a state shown in Figures 1 and 2. In this state, the
cap 7 is fully closed and therotary shaft 15 is in the locking position where it engages with the upper inclined surface of thestopper portions 74 of thecap 7 to keep thecap 7 closed. - When the lighter 1 is to be used or ignited, the
side wheels 14 are pushed downward and rotated, whereby theside wheels 14 are moved to depress the flint 11 and therotary shaft 15 in theinclined grooves 52 is moved to the releasing position so that thestopper portion 74 of thecap 7 is disengaged from therotary shaft 15 as shown in Figure 3, and at the same time, thefile wheel 13 is rotated to strike the flint 11 and sparks are generated. - As shown in Figure 4, when the
stopper portion 74 of thecap 7 is disengaged from therotary shaft 15, thecap 7 is opened under the force of thespring 76 to expose theburner member 6 and the sparks ignite the fuel on theburner member 6. When theside wheels 14 are released, therotary shaft 15 is moved upward to the locking position under the force of theflint urging spring 12. - When the
cap 7 is closed, the flame is quenched. As thecap 7 approaches its closed position, the lower inclined surface of thestopper portion 74 is brought into abutment against therotary shaft 15 and begins to push therotary shaft 15 toward the releasing position as shown in Figure 5. - As the
cap 7 further approaches its closed position, thestopper portion 74 moves therotary shaft 15 downward rearward toward the releasing position along the upper edges of theinclined grooves 52 as shown in Figure 6. When thecap 7 reaches its closed position as shown in Figure 7, therotary shaft 15 is disengaged from the lower inclined surface of thestopper portion 74 and comes to be moved to the locking position under the force of theflint urging spring 12. In the locking position, therotary shaft 15 is pinched between the upper inclined surface of thestopper portion 74 and the upper edges of theinclined grooves 52 and keeps thecap 7 closed. - In the lighter 1 of this embodiment, the lighter 1 can be ignited only by rotating the
side wheels 14 without opening thecap 7. Further, after thecap 7 is closed, thecap 7 is locked in the closed position by engagement between thestopper portion 74 and therotary shaft 15 and thecap 7 is prevented from being accidentally opened. - In addition, all of the contents of Japanese Patent Application No. 11(1999)-346093 are incorporated into this specification by reference.
