Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
197 words
A piezoelectric gas lighter comprising a casing; a fuel reservoir disposed within said casing; a burner valve associated with said fuel reservoir for permitting the egress of fuel therefrom; a piezoelectric generator housed in said casing and having a piezoelectric element for generating a high voltage in response to a compressive force and force means arranged in alignment with said piezoelectric element to exert said compressive force thereon; a block member disposed on said fuel reservoir; a thumb piece pivotally supported on said block member and rotatable in perpendicular relation to the movement of said force means of said piezoelectric generator; and a cam lever operatively associated with said thumb piece to transmit the movement of said thumb piece to said force means of said piezoelectric generator; and spark means connected to said piezoelectric element for igniting said fuel emitted by said burner valve in response to said high voltage whereby the rotation of said thumb piece causes said piezoelectric element to be applied with said compressive force in a direction perpendicular to said rotation through said cam lever to generate a high voltage in the piezoelectric element which actuates said spark means to ignite said fuel.
Claim 2
Dependent Claim
197 words
A piezoelectric gas lighter comprising a casing; a fuel reservoir disposed within said casing; a burner valve associated with said fuel reservoir for permitting the egress of fuel therefrom; a piezoelectric generator housed in said casing and having a piezoelectric element for generating a high voltage in response to a compressive force and force means arranged in alignment with said piezoelectric element to exert said compressive force thereon; a block member disposed on said fuel reservoir; a thumb piece pivotally supported on said block member and rotatable in perpendicular relation to the movement of said force means of said piezoelectric generator; and a cam lever operatively associated with said thumb piece to transmit the movement of said thumb piece to said force means of said piezoelectric generator; and spark means connected to said piezoelectric element for igniting said fuel emitted by said burner valve in response to said high voltage whereby the rotation of said thumb piece causes said piezoelectric element to be applied with said compressive force in a direction perpendicular to said rotation through said cam lever to generate a high voltage in the piezoelectric element which actuates said spark means to ignite said fuel.
Claim 3
Dependent Claim
59 words
A lighter according to claim 1, wherein said thumb piece includes at one end thereof a roller rotatably supported thereon and at the other end an actuating means adapted to receive an operating force effecting the rotation of said thumb piece, said roller is operatively associated with said cam lever to transmit said operating force to said piezoelectric generator.
Claim 4
Dependent Claim
42 words
A lighter according to claim 2, wherein said actuating means of said thumb piece is provided thereon at the most distant surface from the pivot of said thumb piece in order to prevent a thumb from slipping off from said thumb piece.
Claim 5
Dependent Claim
45 words
A lighter according to claim 2, wherein said cam lever has at one end thereof a portion actuated by said roller of said thumb piece and at the other end thereof a roller pivotally supported thereon to apply a compressive force to said piezoelectric generator.
Claim 6
Dependent Claim
33 words
A lighter according to claim 4, wherein said cam lever has at least one portion adapted in the operative condition of the lighter to engage a controL lever to open said burner valve.
Claim 7
Dependent Claim
24 words
A lighter according to claim 4, wherein each roller respectively formed on said thumb piece and said cam lever is made of synthetic resins.
Claim 8
Dependent Claim
35 words
A lighter according to claim 1, wherein said lighter includes a cap pivotally mounted on an upper open end of said casing and thumb piece is concealed therein in the inoperative position of the lighter.
