MULTI-MODE LIGHTER Russian patent published in 2005 - IPC

FIELD: lighters.

SUBSTANCE: proposed lighter has body to which fuel is delivered, drive member for selective ignition of fuel which is connected with body and shifting member; shifting member is shifted by user between its first and second positions by application of first switching-on force to drive member for ignition of fuel when shifting member is placed in first position and second switching0on force when shifting member is placed in second position; first switching-on force is greater than second switching-on force. Second switching-on force is lesser that first switching-on force by approximately 5 kg and greater by approximately 1 kg. Drive member is made in form of trigger movably connected with body or in form of connecting rod; first drive member selectively proportions fuel and initiates ignition unit. Ignition unit is provided with peiezoelectric device. Lighter is additionally provided with locking member connected with body and functionally connected with shifting member. Locking member includes additionally first and second ends; second end is shiftable from initial position when shifting member is placed in first position to final position when shifting member is placed in second position. When shifting member is in second position it is brought in contact with drive member. Shifting member is functionally connected with drive member when shifting member is placed in second position and shifting member is disconnected from drive member when it is placed in first position. Shifting member includes cylindrical helical spring, plate spring and torsion spring which is V-shaped spring and metal spring; shifting member is also provided with first and second legs; second leg is immovably secured on body; when shifting member is placed in first position, first leg of spring is brought in contact with drive member. After repeated action of lighter, first switching-on force remains practically constant. Lighter is designed to operate at application of force to drive member lesser than 10 kg when shifting member is placed in first position. Lighter if adapted to operation at application of force lesser than 5 kg to drive member when shifting member is placed in second position. Drive member is not locked against motion. Lighter is adapted for operation by application of force to drive member when shifting member is placed in first position. Lighter is adapted for operation by shifting the locking member and drive member when shifting member is placed in second position. Locking member moves owing to elastic bend. Lighter is adapted for operation by moving the locking member till motion of drive member when shifting member is placed in second position.

EFFECT: avoidance of unwanted operation of lighter.
