Abstract

Abstract The invention is concerned with a gas-burning cigarette lighter having an ignition mechanism of the kind in which gaseous fuel is ignited in an ignition zone downstream of a burner nozzle by means of a spark generated between a pair of electrodes by the impact of a hammer with a piezoelectric element, one of the hammer and element moving under spring action into engagement with the other of a hammer and element. The mechanism is operated by manual movement of an actuating member from the rest position to an operative position in which part of the actuating member lies outside the confines of the lighter body as defined when the actuating member is in the rest position. The operative movement of the actuating member causes firstly one of the hammer and element to move with the actuating member and away from the other one of the hammer and element to provide or to increase the impact stroke and to cock the mechanism and secondly one of the hammer and element to be released so that it is free to move under the spring action.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 205 words
In an ignition mechanism for a gas-burning cigarette lighter having an ignition zone and comprising a hammer member and a piezoelectric member, one of which members forms part of a movably mounted assembly, and spring means biasing the other of said members toward the member forming part of said movable assembly, and in which a fuel-igniting spark is generated between a pair of electrodes by impact between said members, the improvement which comprises actuating means mounted for movement from a rest position in a direction away from said ignition zone to an operative position in which part of the actuating means lies outside the confines of the lighter body as defined when the actuating means is in the rest position, said actuating means being connected to thereby move said movably mounted assembly into a position in which part of said assembly also lies outside the confines of the lighter body as hereinbefore defined, thus first moving the member forming part of said assembly away from the other of said members and compressing said spring, and then releasing said spring-biased member, whereupon said spring means drives said last-mentioned member into engagement with the member which has moved with the actuating means away from said rest position.
Claim 2
Dependent Claim 205 words
In an ignition mechanism for a gas-burning cigarette lighter having an ignition zone and comprising a hammer member and a piezoelectric member, one of which members forms part of a movably mounted assembly, and spring means biasing the other of said members toward the member forming part of said movable assembly, and in which a fuel-igniting spark is generated between a pair of electrodes by impact between said members, the improvement which comprises actuating means mounted for movement from a rest position in a direction away from said ignition zone to an operative position in which part of the actuating means lies outside the confines of the lighter body as defined when the actuating means is in the rest position, said actuating means being connected to thereby move said movably mounted assembly into a position in which part of said assembly also lies outside the confines of the lighter body as hereinbefore defined, thus first moving the member forming part of said assembly away from the other of said members and compressing said spring, and then releasing said spring-biased member, whereupon said spring means drives said last-mentioned member into engagement with the member which has moved with the actuating means away from said rest position.
Claim 3
Dependent Claim 216 words
In an ignition mechanism for a gas-burning cigarette lighter comprising a burner nozzle, a hammer member and a piezoelectric member, one of which members forms part of a movably mounted assembly, and spring means biasing one of said members toward the other member, and in which a fuel-igniting spark is generated between a pair of electrodes by impact between said members, the improvement which comprises actuating means including an actuating member which extends across the top of the lighter with one end adjacent the burner nozzle, said actuating means being mounted for movement from a rest position in a direction backward and downward away from the nozzle to an operative position in which part of the actuating means lies outside the confines of the lighter body as defined when the actuating means is in the rest position, said actuating means being connected to move said movably mounted assembly into a position in which part of said assembly also lies outside the confines of the lighter body as hereinbefore defined, thus first moving the member forming part of said assembly away from the other of said members and compressing said spring, and then releasing said spring-biased member so that it is free to move in response to said spring bias toward the other end of said members.
Claim 4
Dependent Claim 216 words
In an ignition mechanism for a gas-burning cigarette lighter comprising a burner nozzle, a hammer member and a piezoelectric member, one of which members forms part of a movably mounted assembly, and spring means biasing one of said members toward the other member, and in which a fuel-igniting spark is generated between a pair of electrodes by impact between said members, the improvement which comprises actuating means including an actuating member which extends across the top of the lighter with one end adjacent the burner nozzle, said actuating means being mounted for movement from a rest position in a direction backward and downward away from the nozzle to an operative position in which part of the actuating means lies outside the confines of the lighter body as defined when the actuating means is in the rest position, said actuating means being connected to move said movably mounted assembly into a position in which part of said assembly also lies outside the confines of the lighter body as hereinbefore defined, thus first moving the member forming part of said assembly away from the other of said members and compressing said spring, and then releasing said spring-biased member so that it is free to move in response to said spring bias toward the other end of said members.
Claim 5
Dependent Claim 213 words
In an ignition mechanism for a gas-burning cigarette lighter comprising a hammer member and a piezoelectric member, one of which members forms part of a movably mounted assembly, and spring means biassing one of said members toward the other member, and in which a fuel-igniting spark is generated between a pair of electrodes by impact between said members, the improvement which comprises actuating means mounted for movement from a rest position to an operative position in which part of the actuating means lies outside the confines of the lighter body as defined when the actuating means is in the rest position, said actuating means being connected to thereby move said movably mounted assembly into a position in which part of said assembly also lies outside the confines of the lighter body as hereinbefore defined, thus first moving the member forming part of said assembly away from the other of said members and compressing said spring, and then releasing said spring-biased member so that it is free to move in response to said spring bias toward the other of said members, and said actuating means comprising a member defining a recess which receives the part of said assembly which is moved to a position outside the confines of said lighter body as hereinbefore defined.
Claim 6
Dependent Claim 213 words
In an ignition mechanism for a gas-burning cigarette lighter comprising a hammer member and a piezoelectric member, one of which members forms part of a movably mounted assembly, and spring means biassing one of said members toward the other member, and in which a fuel-igniting spark is generated between a pair of electrodes by impact between said members, the improvement which comprises actuating means mounted for movement from a rest position to an operative position in which part of the actuating means lies outside the confines of the lighter body as defined when the actuating means is in the rest position, said actuating means being connected to thereby move said movably mounted assembly into a position in which part of said assembly also lies outside the confines of the lighter body as hereinbefore defined, thus first moving the member forming part of said assembly away from the other of said members and compressing said spring, and then releasing said spring-biased member so that it is free to move in response to said spring bias toward the other of said members, and said actuating means comprising a member defining a recess which receives the part of said assembly which is moved to a position outside the confines of said lighter body as hereinbefore defined.
