Ignition operating mechanism for slide type lighters

An ignition operation mechanism for slide type lighter comprising an operation member for performing a slide operation along a curved surface portion at one edge of the upper portion of a lighter main body by rotating about a pivot at substantially the center of the curved surface portion for pushing down a piezoelectric mechanism, characterized in that:

• a support portion as a pivot of rotation of the operation member is shaped and sized to have a predetermined clearance to move up and down the pivot portion within the support member at the lighter main body side for rotatably supporting the fulcrum member;
• and
• the pivot portion of the operation member is normally spring biased to the upper position inside the support member but can be moved down inside the support member by the downward pushing of the operation member subsequent to the slide operation for enabling spark ignition by the piezoelectric mechanism.

• a portion to be pushed of the piezoelectric mechanism in abutment against for pushing a pushing portion of the operation member is constructed to fall out of the pushing portion at the final stage of the slide operation of the operation member;
• and
• downwardly pushing operation of the operation member subsequent to the slide operation deforms the operation member for forcing the portion to be pushed to push down for enabling the spark ignition by the piezoelectric mechanism.

• a pushing portion of the operation member for pushing by striking a portion to be pushed of the piezoelectric mechanism is restricted in the downward movement of the portion to be pushed at the final stage of the slide operation of the operation member not to reach the spark ignition;
• and
• push-down operation of the operation member subsequent to the slide operation forces the operation member to deform and pushes down the portion to be pushed to enable the spark ignition by the piezoelectric mechanism.

• the one edge of the upper portion of the lighter main body restricts the slide operation of the operation member in position not to cause the spark ignition by the piezoelectric mechanism at the final stage of the slide operation of the operation member.

An ignition operation mechanism for slide type lighter comprising an operation member for performing a slide operation along a curved surface portion at one edge of the upper portion of a lighter main body by rotating about a pivot at substantially the center portion of the curved surface portion for pushing down a piezoelectric mechanism, characterized in that:

• a rotary lever portion of the operation member strikes an upper edge of the lighter main body at the final stage of the slide operation of the operation member to restrict the movement of the operation member in the slide direction not to reach the spark ignition by the piezoelectric mechanism;
• and
• push-down operation of the operation member subsequent to the slide operation forces the operation member to deform and raise the portion to be pushed to enable the spark ignition by the piezoelectric mechanism.
