FIG. 1 and comprises afuel reservoir 1, anignition mechanism 2, and aflame spout 3. Thefuel reservoir 1 is filled with pressurized flammable fuel. Theflame spout 3 is provided at an open end of a projected portion of thefuel reservoir 2. Theflame spout 3 is in fluid communication with thefuel reservoir 1. Aspark member 4 is provided in theflame spout 3. Thespark member 4 is adapted to produce a spark at theflame spout 3 as fuel supplied from thefuel reservoir 2 thereto. Thus, fuel is burned at theflame spout 3 to produce a flame. The lighter is typically carried in a pocket or bag. However, it is often that theflame spout 3 is clogged by inserted foreign objects (e.g., key or pen). As such, thespark member 4 is damaged. The lighter thus may malfunction (i.e., inoperative). Also, flame has the characteristic of burning upward. Thus, flame may not reach certain points (i.e., dead ends) above the ignition (i.e., effective burning being impossible). Alternatively, flame may reach theflame spout 3 to damage it. Thus, it is desirable to provide an improved lighter in order to overcome the inadequacies of the prior art and bring a more convenient use. - After considerable research and experimentation, a lighter according to the present invention has been devised so as to overcome the above drawbacks (e.g., the flame spout clogged by inserted foreign objects, spark member damaged, lighter malfunctioned, and burning dead ends) of the prior art.
- It is an object of the present invention to provide a lighter comprising a body including a recess at its forward end; a flame spout received in the recess, the flame spout having both sides in its rear in pivotal connection to both sides of the recess such that the flame spout is adapted to pivot about the recess to either fully retract into the body so as to protect the flame spout and prevent same from being damaged due to collision or dispose away from the body; and a limiting assembly movably disposed proximate the flame spout, the limiting assembly being adapted to fasten the flame spout when the flame spout is disposed at a predetermined angle about the body by pivoting away from the body. By utilizing this lighter, flame may throw out of the flame spout at the predetermined angle.
- In one aspect of the present invention two tabs are provided at both sides of the limiting assembly, two pins are provided at both sides of the flame spout and the body, either pin comprises an end stop of hollow disk, the stop comprises a plurality of grooves equally spaced apart each extended from an outer edge of the stop to its center, and the tab at either side of the limiting assembly is adapted to dispose in the corresponding groove such that the limiting assembly is adapted to secure to the pin for stopping the pivoting of the flame spout.
- In another aspect of the present invention there is provided a positioning member at the other end of the limiting assembly, the positioning member including two opposite side tabs, and the flame spout includes a through hole on one side, the through hole including a central, circular hole and a plurality of troughs extended outward from the circular hole, the troughs being equally spaced each other and each trough being shaped and conformed to slidably receive either tab such that the positioning member is adapted to pass the circular hole and any pair of the aligned troughs for fastening the flame spout, thereby prohibiting the flame spout from pivoting.
- The above and other objects, features and advantages of the present invention will become apparent from the following detailed description taken with the accompanying drawings.

FIG. 5 is an exploded view of a first preferred embodiment of lighter according to the invention; and -
FIG. 6 is a cross-sectional view of the lighter ofFIG. 5 . - Referring to
FIGS. 2 and 3 , a lighter in accordance with the invention is shown. The lighter comprises a parallelepipedhollow body 10 and aflame spout 20. Thebody 10 comprises arecess 11 at its forward end. Therecess 11 is adapted to receive theflame spout 20. Theflame spout 20 has both sides in pivotal connection to both sides of therecess 11 in thebody 10. Thus, theflame spout 20 is adapted to pivot about therecess 11 to fully retract into thebody 10. Thus, theflame spout 20 is protected. Otherwise theflame spout 20 may damage due to collision. Alternatively, theflame spout 20 may pivot relative to therecess 11 away from thebody 10. In the lighter there is further provided alimiting assembly 30 in theflame spout 20. Thelimiting assembly 30 is adapted to fasten theflame spout 20 of the lighter such that theflame spout 20 may fasten in thebody 10 or thelimiting assembly 30 may fasten theflame spout 20 in its pivotal leaving action (seeFIG. 4 ). Thus, theflame spout 20 may be disposed at a predetermined angle about thebody 10. As an end, flame may throw out of theflame spout 20 at the predetermined angle. - Referring to
FIGS. 3 and 4 , a first preferred embodiment of the invention is shown. Aspace 21 is defined in theflame spout 20. Thelimiting assembly 30 is received in thespace 21 proximate a pivotal portion of theflame spout 20 and thebody 10. Thelimiting assembly 30 comprises arectangular body 301 and aflange 31 at one end of thebody 301 spaced from a surface of theflame spout 20. Aprotrusion 33 is provided at the other end of thebody 301 opposite theflange 31. An elastic member (e.g., spring) 34 is put on theprotrusion 33. Twotabs 32 are provided at both sides of thebody 301 proximate theprotrusion 33. - Referring to
FIGS. 3 and 4 again, theflame spout 20 comprises twofirst holes 25 at its both sides also proximate both sides of thelimiting assembly 30. Thebody 10 further comprises twosecond holes 12 at both sides of therecess 11 aligned with thefirst holes 25. Eitherpin 24 is inserted into the aligned first andsecond holes recess 11. Thepin 24 comprises acylinder 240 at one end, astop 23 at the other end connected to thecylinder 240. Thecylinder 240 is inserted into the aligned first andsecond holes body 10 and the flame spout 20 together. Thestop 23 abuts against an inner surface of theflame spout 20. Thestop 23 is a hollow disk and comprises a plurality ofgrooves 241 equally spaced apart each extended from an outer edge of thestop 23 to its center. Thetab 32 at either side of the limitingassembly 30 is adapted to dispose in thecorresponding groove 241. As such, the limitingassembly 30 may be releasably secured to thepin 24. Thus, theflame spout 20 may not pivot since thepins 24 are fixed. Further, an internal raisedmember 22 of U-shaped is provided in theflame spout 20 facing one end of theprotrusion 33 so as to prevent theprotrusion 33 from moving out of the raisedmember 22. - Referring to
FIGS. 3 and 4 , in response to pushing theflange 31 toward the raisedmember 22 theelastic member 34 on theprotrusion 33 contacts the raisedmember 22 to be compressed thereby. Also, thestops 23 are disposed at a moving path (i.e., both sides) of theflange 31 for limiting the movement of the limitingassembly 30. Both sides of theflange 31 are stopped by thestops 23 so as to prevent the limitingassembly 30 from pushing out of theflame spout 20. Otherwise, the limitingassembly 30 may not able to return to its original position. At this time, thetabs 32 clear thegrooves 241 to enter a center of thestop 23. Thus, theside tabs 32 of the limitingassembly 30 disengage with thepins 24. As such, theflame spout 20 may pivot as thepins 24 rotate. To the contrary, in a case of theflame spout 20 pivoted farther away from therecess 11 of thebody 10 and the pushing force removed, elastic force stored by the compressedelastic member 34 may force theside tabs 32 of the limitingassembly 30 to slide along surfaces of thestops 23 until theflame spout 20 pivots to a predetermined angle. Thus, theside tabs 32 of the limitingassembly 30 face another twogrooves 241. The compression force of theelastic member 34 pushes thetabs 32 to enter another twogrooves 241. The limitingassembly 30 returns to its original position as theelastic member 34 compresses. As an end, theflame spout 20 is fastened again (i.e., rotation being prohibited). - Referring to
FIGS. 5 and 6 , a second preferred embodiment of the invention is shown. The limitingassembly 30 is provided in thebody 10 and theflame spout 20. The limiting assembly 30 comprises a bar 35 of half cylindrical section, a push button 36 at an outer end of the bar 35, the push button 36 being projected from an outer surface of the body 10 to be distal from one side of the recess 11, a flange 37 formed on the bar 35 proximate the push button 36, the flange 37 being disposed in the body 10 and an outer surface of the flange 37 facing the push button 36 being abutted against an inner surface of the body 10, an elastic member 34 put on the bar 35, the elastic member 34 on the bar 35 being urged against the flange 37 opposite the push button 36 (i.e., on a portion of the bar 35 within the body 10), the elastic member 34 being adapted to compress to store energy to force the limiting assembly 30 to return to its original position, and a positioning member 38 at the other end of the bar 35 distal the push button 36 (i.e., the positioning member 38 provided at the other end of the bar 35), the positioning member 38 including two opposite side tabs 32, the positioning member 38 being disposed on an inner surface of the flame spout 20 with the tabs 32 fastened at the flame spout 20 so as to dispose at an angle about the body 10. - Referring to
FIGS. 5 and 6 again, thebody 10 is a hollow parallelepiped and comprises athird hole 13 on one side distal therecess 11 for permitting thepush button 36 to dispose therein, afourth hole 14 on one side of therecess 11 aligned with thethird hole 13 in thebody 10 for permitting the positioningmember 38 to dispose therein, twoprotrusions 15 at both sides of thefourth hole 14 of thebody 10, theprotrusions 15 being adapted to contact theflange 37 for preventing theflange 37 from moving further toward thefourth hole 14, and afifth hole 16 on the other side of therecess 11 opposite thefourth hole 14 on thebody 10. - Referring to
FIGS. 5 and 6 again, theflame spout 20 comprises a throughhole 26 on one side aligned with thefourth hole 14, the throughhole 26 being adapted to permit the positioningmember 38 to pass, the throughhole 26 including a central,circular hole 27 and a plurality of (e.g., four)troughs 241 extended outward from thecircular hole 27, thetroughs 241 being equally spaced each other and eachtrough 241 being shaped and conformed to slidably receive eithertab 32 such that the positioningmember 38 is adapted to pass thecircular hole 27 and either pair of alignedtroughs 241 so as to fasten the limitingassembly 30 in theflame spout 20. Theflame spout 20 comprises apin 24 on the other side opposite thefourth hole 14, thepin 24 disposed in thefifth hole 16 to contact thebody 10. Thus, the limitingassembly 30 may pass the third, the fourth, and the throughholes body 10 into theflame spout 20. The positioningmember 38 is provided in the throughhole 26. Theflange 37 and theelastic member 34 put on thebar 35 are provided between the third and thefourth holes push button 36 is projected from thethird hole 13 out of the body 10 (i.e., exposed to an outer surface of the body 10). - Referring to
FIGS. 5 and 6 again, theelastic member 34 on thebar 35 is prevented from passing the fourth 14 when a pushing force exerts on thepush button 36 to push it toward thebody 10. An in turn, theelastic member 34 urges an inner surface of thebody 10 to compress against the inner surface of thebody 10 and theflange 37. Thus, theflange 37 contacts theprotrusions 15 to prevent the limitingassembly 30 from being moved out of its predetermined position. At this time, the positioningmember 38 moves toward thespace 21 to clear the throughhole 26. Thus, thetabs 32 clear the throughhole 26. At this time, thebar 35 serves the same as thepin 24 with respect to both theflame spout 20 and thebody 10. As such, theflame spout 20 may pivot out of thebody 10 about thebar 35 and thepin 24. To the contrary, in a case of theflame spout 20 pivoted farther away from therecess 11 of thebody 10 and the pushing force removed, elastic force stored by the compressedelastic member 34 may force theside tabs 32 of the positioningmember 38 to urge against an inner surface of theflame spout 20 until theflame spout 20 pivots in an opposite direction to a predetermined angle about thebody 10. Also, thetabs 32 of the positioningmember 38 face another pair oftroughs 241. The expansion force of theelastic member 34 forces the positioningmember 38 to return to its original position. As a result, theflame spout 20 is prohibited from pivoting due to fastening. - Referring to
FIGS. 5 and 6 again, in both of the above embodiments afuel reservoir 40 filled with flammable gas is provided in a rear portion of thebody 10 distal therecess 11. Avalve 41 is provided at a front end of thefuel reservoir 40 for permitting flammable gas to exit. Apipe 42 is extended from thevalve 41 through thepin 24 into theflame spout 20. Anarc generator 50 is provided in thebody 10 proximate thefuel reservoir 40. Thearc generator 51 comprises anspark wire 51 extended through thepin 24 into theflame spout 20 to be adjacent thepipe 42. Thus, a pressing of thearc generator 50 may cause thespark wire 51 to produce a spark. Also, atrigger 60 is projected from an outer surface of thebody 10. One end of thetrigger 60 is connected to both thevalve 41 and thearc generator 50. Thus, pressing thetrigger 60 will press both thevalve 41 and thearc generator 50 to open thevalve 41. And in turn, flammable gas exits thefuel reservoir 40. At the same time, spark is produced by thespark wire 51. As a result, flame occurs as the flammable gas burns in theflame spout 20. - Moreover, within the
body 10 there are further provided afuel adjustment valve 43 and anignition button 61. Thefuel adjustment valve 43 is disposed at one side of thefuel reservoir 40 and exposed to thebody 10. Thefuel adjustment valve 43 is adapted to adjust amount of flammable gas to be supplied from thefuel reservoir 40. As such, flame can be controlled. Further, theignition button 61 is adapted to movably insert into thetrigger 60. Top of thetrigger 60 is formed on an outer surface of thebody 10. Disabling theignition button 61 will force theignition button 61 to insert into thetrigger 60. Thus, thetrigger 60 is prevented from exerting a pressing force onto both thevalve 41 and thearc generator 50. As an end, the lighter is disabled. - In view of above, the
flame spout 20 and thebody 10 of the lighter are pivotably connected together. Thus, theflame spout 20 may pivot to either retract into therecess 11 to receive in thebody 10 or extend away from thebody 10 to leave therecess 11. Also, thetabs 32 disposed in thetroughs 241 may fasten theflame spout 20 at therecess 11 in its pivotal leaving action. Thus, theflame spout 20 is disposed at a predetermined angle about thebody 10. The invention has the following advantages: (1) Theflame spout 20 received in therecess 11 of thebody 10 is protected. Also, thespark wire 51 in theflame spout 20 is prevented from being damaged by inserted foreign objects. (2) Theflame spout 20 fastened at therecess 11 in its pivotal leaving action causes theflame spout 20 to dispose at a predetermined angle about thebody 10. Thus, flame can reach dead ends for carrying out an effective burning. - While the invention herein disclosed has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
