Definitions

  • the invention relates to a dislocation-type safety lighter, and more particularly, to a dislocation-type safety lighter that increases the height of the pressing part making the user laborious rather than labor saving in exerting force to ignite the lighter to avoid the children in playing around the lighter to cause fire accident but still within the force-exerting capability for the adult user.
  • the simple-type lighter provides consumers with conveniency and low cost, and claims to be a great breakthrough in the contemporary era ever since the first use of fire in material civilization of human history.
  • the lighter brings forth concerns on safety consideration. Particularly, the child playing with the lighter may result in fire accident. According to an old saying, a tiny spark may spread to become a prairie fire. Therefore, it cannot be too careful to use the lighter.

  • the wheel racket ( 2 ) is slipped on the top of the corresponding sealing part ( 11 ) of the main body ( 1 ).
  • the wheel racket ( 2 ) having a securing seat ( 22 ) provided at the center thereof and having a pair of file-wheel seats ( 21 ) provided by extending from both sides and standing upright on opposite sides thereof is capable of containing a spring ( 32 ) and a flint ( 31 ).
  • a securing hole ( 211 ) is provided on each of the file-wheel seats ( 21 ) near the top end thereof, and a securing hole ( 212 ) is also provided on each of the file-wheel seats ( 21 ) near the bottom end thereof.
  • the wheel racket ( 2 ) also provides an adjusting ring ( 23 ) having a plurality of inner row teeth ( 231 ) on the inner surface that are capable of meshing with the outer row teeth ( 121 ) on the outer surface of the nozzle seat ( 12 ).
  • the adjusting ring ( 24 ) is used for adjusting the quantity of liquid-gas output in the main body ( 1 ).
  • the lever ( 5 ) includes a pressing part ( 51 ), a base ( 52 ), and a slipping hole ( 53 ).
  • Each side of the base ( 52 ) furnishes a salient part ( 521 ) used to be the pivot point C of the lever ( 5 ).
  • the salient parts ( 521 ) are fitted in the securing holes ( 212 ) near the bottom of the file-wheel seats ( 21 ), and the securing holes ( 212 ) are used as pivot seat for bearing the salient parts ( 521 ).
  • the slipping hole ( 53 ) being used as the point B of resisting force R (not shown in the Figure) passes through the nozzle ( 13 ) and slips on the neck part ( 131 ) of the nozzle ( 13 ) of the sealing part ( 11 ).
  • the pressing part ( 51 ) provided at an end of the lever ( 5 ) is used to be the “point A” of exerting force P.
  • the metal cap ( 4 ) is slipped on the top of the lighter to form the simple-type lighter that is most popular in the market nowadays.
  • x-x′ and y-y′ be the horizontal and vertical lines passing through the pivot point C while the vertical line crosses the rim of the file wheel ( 3 ) at a lowest and highest point of “L” and “V” respectively, and the inclined angle of the between the connecting line CE of the lever ( 5 ) is ⁇ ′ from the horizontal line x-x′, the elevation at the “point A” of exerting force P of the lever ( 5 ) is the same as that of the lowest point L, and the pivot point C is adjacent to the point L.
  • the user in order to use his/her thumb to press the pressing part ( 51 ) by exerting a force P at the “point A” of exerting force P on the lever ( 5 ) so as to pump the liquid-gas from the nozzle ( 13 ) of the main body ( 1 ) at the “point B” of resisting force R (not shown in the Figure), he/she uses his/her thumb to drive the file wheel ( 3 ) quickly from the point V making the file wheel ( 3 ) rub the flint ( 31 ) to generate spark and slides sequentially in counter-clockwise direction toward the “point A” of exerting force P at an end of the lever ( 5 ), the liquid-gas pumped out to meet the spark generated is ignited to generate flames.
  • the angle ⁇ ′ is an angle between the line CE that passes through the pivot point C and the “point A” of exerting force P and the line x-x′
  • the angle ⁇ 0 is an angle made between the line CE and the line y-y′.
  • the invention provides a dislocation-type safety lighter that aims to ameliorate at least some of the demerits of the prior art or to provide a useful alternative.
  • the primary objective of the invention is to provide a dislocation-type safety lighter making use of the fact that the height H of the “point A” of exerting force P relative to the pivot point C is relatively higher than that of the height H of the prior art. This will make a relatively larger angle ⁇ ′ and relatively smaller ⁇ 0 to reduce the acting distance of the user's thumb to operate the lighter. This will make the user harder to exert force to ignite the lighter but the exerting force required is still within the capability of the user while makes the children harder to cause fire accident.
  • the invention provides a dislocation-type safety lighter that includes a main body, a wheel racket, a file wheel, a metal cap, and a lever.
  • the lever includes a pressing part, a base, and a slipping hole.
  • Each side of the base furnishes a salient part used to be the pivot point C of the lever.
  • the salient parts are fitted in the securing holes near the bottom of the file-wheel seats, and the securing holes are used as pivot seat for bearing the salient parts.
  • the metal cap is capped on the top of the wheel racket to cover the file wheel and the lever.
  • the height H between the elevation of of the “point A” of exerting force P and the elevation of the pivot point C is in the range (1 ⁇ 3)H′*H*(2 ⁇ 3)H′ where the height H′ is equal to the diameter of the file wheel ( 3 ).
  • the larger the height H the more laborious it is to turn the file wheel by the thumb of the user that makes the children whose exerting force is relatively weak harder to ignite the lighter.
  • the lighter of the invention is capable of improving the efficacy of safety usage. Nevertheless, the exerting force P is still within the range of an adult user.
  • FIG. 1 is an exploded view of a simple-and-lever-type lighter structure of the prior art.
  • FIG. 2 is a half sectional-view of the simple-and-lever-type lighter structure of the prior art.
  • FIG. 3 is an exploded view of a dislocation-type safety lighter structure of the preferred embodiment of the invention.
  • FIG. 4 is a half sectional-view of the dislocation-type safety lighter structure of the first embodiment of the invention.
  • FIG. 5 is a half sectional-view of the dislocation-type safety lighter structure of the second embodiment of the invention.
  • FIG. 3 is an exploded view of a dislocation-type safety lighter structure of the preferred embodiment of the invention.
  • the dislocation-type safety lighter of the first embodiment of the invention includes a main body ( 1 ), a wheel racket ( 2 ), a file wheel ( 3 ), a metal cap ( 4 ), and a lever ( 5 ).
  • the main body ( 1 ), wheel racket ( 2 ), the file wheel ( 3 ), the metal cap ( 4 ) are all pretty much similar to those of the simple-and-lever-type lighter structure of the prior art, thereby it is not necessary to repeat here.
  • the lever ( 5 ) includes a pressing part ( 51 ), a base ( 52 ), and a slipping hole ( 53 ).

  • the point A of the exerting force P exerting at the pressing part ( 51 ) at an end of the lever ( 5 ) is assumed as a “point A” of exerting force P.
  • the height H of the “point A” of exerting force P is one third of the height H′ of the vertex point “V” of the diameter of the file wheel ( 3 ) measuring from the line x-x′, and the pivot point C is positioned adjacent to the bottom part of the vertical central line of the file wheel ( 3 ).
