Abstract
A child resistant flint lighter having a body on which a pair of brackets are formed, a pivotal means being of bar-shaped and installed on the pair of brackets, a free wheel rotatably installed on the pivotal means, a flint wheel covering on the pivotal means, a fixed wheel covering on the pivotal means and fixed with respect to the flint wheel, a flint with respect of which the flint wheel and fixed wheel is able to rotate, and a flint spring pressing the flint on the flint wheel. In this invention, there is only one bar-shaped pivotal means needed in stead of the complex shafts in the conventional lighter. It will significantly reduce the complexity and time of manufacturing and assembling the pivotal means to the lighter.
Description
- 1. Field of the Invention
- The invention relates to a child resistant gas lighter with a free wheel a diameter of which is a certain larger than a fixed wheel thereof and being able to both prevent child from using and lower a cost of manufacturing.
- 2. Description of the Prior Art
- Flint gas lighters having child resistant mechanism have long been developed. One conventional such kind of lighter is disclosed in a Chinese utility model patent bearing a patent number of “ZL 200620055328.4” and published on Feb. 28, 2007. As shown in
FIG. 1 , thegas lighter 90 has twoshafts brackets fixed wheel 93 forming on oneshaft 91′ and afree wheel 94 forming on theother shaft 91, aflint wheel 95 formed on the twoshafts flint 96, and aflint spring 97 pressing theflint 96 on theflint wheel 95. Thefree wheel 94, a diameter of which is a certain larger than thefixed wheel 93, is freely rotatable with theshaft 91, which makes a child, whose thumb is smaller than an adult human, be not able to rotate thefree wheel 94 and thefixed wheel 93 at the same time to spark and ignite the lighter. - A drawback of such lighter is that its structure is complex and a cost of manufacturing thus becomes high.
- The main object of the invention is to provide a child resistant flint gas lighter with a free wheel a diameter of which is a certain larger than a fixed wheel thereof and being able to both prevent child from using and lower a cost of manufacturing.
- In order to accomplish the above object, the present invention provides a child resistant flint lighter having a body on which a pair of brackets are formed, a pivotal means being of bar-shaped and installed on the pair of brackets, a free wheel rotatably installed on the pivotal means, a flint wheel covering on the pivotal means, a fixed wheel covering on the pivotal means and fixed with respect to the flint wheel, a flint with respect of which the flint wheel and fixed wheel is able to rotate, and a flint spring pressing the flint on the flint wheel.
- 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 partially cross-sectional view of a conventional child resistant flint gas lighter; -
FIG. 2 is a perspective schematic partial view of an embodiment of the child resistant flint lighter of the invention; -
FIG. 3 is an exploded schematic partial view showing the child resistant flint lighter shown inFIG. 2 ; and, -
FIG. 4 is a partially cross-sectional view of another embodiment of the invention. - With reference to
FIGS. 2 and 3 , a child resistant flint lighter with free wheel of the invention is shown. The lighter 1 has abody 10 on which a pair ofbrackets pivotal means 12 being of bar-shaped and installed on the pair ofbrackets free wheel 15 rotatably installed on thepivotal means 12, aflint wheel 14 covering on thepivotal means 12, a fixedwheel 13 covering on thepivotal means 12 and fixed with respect to theflint wheel 14, aflint 16 with respect of which theflint wheel 14 andfixed wheel 13 is able to rotate, and aflint spring 17 pressing theflint 16 on theflint wheel 14. In the embodiment shown inFIGS. 2 and 3 , thepivotal means 12 is oneintegral bar 121. As shown inFIG. 4 , it can be two basically identicalshorter bars 122 having the same function as theintegral bar 121. - Generally, a radius of the
free wheel 15 is of 0.1 to 1.0, and preferably 0.5, millimeter greater than a radius of thefixed wheel 13. A thickness of thefree wheel 15 is 0.8 to 1.2, and preferably 1.0 millimeter. Theflint wheel 14 and thefixed wheel 13 are able to be either loose- or close-fitted to thepivotal means 12. In the loose fit, thepivotal means 12 is able to either fixed or rotatable with respect to thebrackets pivotal means 12 must be able to rotatable with thebrackets - In use, an adult human is able to hold the lighter with his hand and rotate the
free wheel 15, theflint wheel 14 and the fixedwheel 13 together to spark theflint 16 with his thumb. Generally, there will be enough skin of his thumb that contacts the flint wheel and he is able to spark and ignite the lighter. However, when a user is a child, whose thumb is smaller than the adult user, there is not so much skin contacting theflint wheel 14 so when his thumb moves, only thefree wheel 15 rotates and he is not able to spark and ignite the lighter. - It could be seen from above description, there is only one bar-shaped pivotal means needed in stead of the complex shafts in the conventional lighter. It will significantly reduce the complexity and time, thus cost, of manufacturing and assembling the pivotal means to the lighter.
- One skilled in the art will understand that the embodiment of the present invention as shown in the drawings and described above is exemplary only and not intended to be limiting.
- It will thus be seen that the objects of the present invention have been fully and effectively accomplished. Its embodiments have 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 such principles. Therefore, this invention includes all modifications encompassed within the spirit and scope of the following claims.
