Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to an amusement lighter and more particularly to a lighter which can be used for making a fire and simultaneously for amusement. 
     The lighter is a device used to start something burning. In order to attract consumers to buy, all lighter manufacturers are doing their best in improving the design and quality of the lighter. However, any improvement in structure gives little change on the function of the lighter. Further, the conventional piezoelectric lighter is very dangerous in use. Error trigger of the piezoelectric switch may cause big trouble. 
     An object of the present invention is to provide a lighter which can be simultaneously used as an amusement device. 
     Another object of the present invention is to provide a lighter which is inexpensive to manufacture and safe in use. 
     Still another object of the present invention is to provide a lighter which is convenient for carriage with oneself and good for serving as an ornament. 
     An embodiment of amusement lighter according to the present invention includes a housing having mounted thereon a L-shaped push rod for driving a piezoelectric switch therein to discharge sparks for ignition, and simultaneously for driving a gear driving device therein to carry five wheels to rotate. The wheels have a variety of patterns printed thereon. When they are driven to rotate, a variety of patterns will be alternatively presented through a show window on the housing of the lighter. A movable pressure plate is attached the lighter so that the piezoelectric switch and the flame hole of the lighter can be stopped when the lighter is fastened to one&#39;s clothing for carriage. 
     The present invention will now be described by way of example, with reference made to the annexed drawings, in which:

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Turning now to the annexed drawings in greater detail and referring first to FIGS. 1 and 2, there is a gas tank (3) set in a rectangular bottom shell (1) at a left side. A rectangular flame hole (12) is made on the bottom shell (1) right above the gas tank (3). A triangular pressure plate (32) is set at the right side of the gas tank (3). A ladder-like shielding plate (33) which extends upwardly from the pressure plate (32) is secured to the gas tank (3) by means of a torque spring (34) and a pin (38) through a hole (35) thereon. A nozzle (37) which extends upwardly from the gas tank (3) is normally pressed by the ladder-like shielding plate (33). A regulating ring (36) which comprises an unitary regulating knob (361) is mounted on the nozzle (37) and connected to the top surface of the gas tank (3). A rectangular control plate (31) which is mounted on the nozzle (37) and set right above the regulating ring (36) is connected to a propulsive device (4) which is set at the right side relative to the control plate (31) and comprises an elongated conical top end (42) having a compression spring (41) thereon. A piezoelectric switch (5) is set at the right side relative to the propulsive device (4) with its ignition wire (51) received in the top underbottom of the bottom shell (1). Three wheels (61), (62) and (63) which have a variety of patterns respectively printed on the face thereof and comprise each an external gear (611), (621) or (631) are sleeved on a positioning rod (6) which is transversely mounted on the bottom shell (1) in a middle position. Another two wheels (71) and (72) which are identical to the said three wheels (61), (62) and (63) in structure and have each an external gear (711) or (721) are sleeved on another positioning rod (7) which is transversely mounted on the bottom shell (1) right below and in parallel with the said three wheels (61), (62) and (63). An L-shaped push rod (8) which has thereon a torque spring (91) and a gear driving device (9) is set in the bottom shell (1) between the wheels (61), (62) and (63), and the wheels (71) and (72). The gear driving device (9) comprises a pair of V-shaped plates (93) and (94) and an end plate (92) spaced from one another at equal distance, wherein the V-shaped plates (93) and (94) have such a common contained angle that the notches (921), (931), (941), (932) and (942) thereof are respectively engaged with the gears (611), (621), (631), (711) and (721). A rectangular front shell (2) is mounted on bottom shell (1) to contain the said parts therebetween. Referring to FIG. 4, the front shell (2) comprises a slant show window (21) through which the patterns on the wheels (61), (62), and (63) can be clearly seen, and two small display holes (211) and (212) for the display of the two lower wheels (71) and (72). Two supporting plates (10) and (103) are set in the front shell (2) corresponding to the two lower wheels (71) and (72). A sliding rod (102) which has a spring (101) thereon is transversely mounted on the two supporting plates (10) with its spring (101) squeezed in therebetween. The sliding rod (102) has a slant front end which protrudes beyond the supporting plate (103) and is connected to the V-shaped plate (93). The bottom shell (1) also comprises a hole (11) through which the regulating knob (361) of the regulating ring (36) protrudes therebeyond. A rectangular hole (321) is made on the bottom shell (1) permitting the moving therethrough of the pressure plate (32). A torque spring (22) is mounted on the back side wall of the bottom shell (1) corresponding to the pressure plate (32) and connected to a clip (20) through which the present amusement lighter can be conveniently attached to one&#39;s pocket or certain part of one&#39;s clothing. 
     Referring to FIGS. 1 and 3 again, the turning of the push rod (8) drives the propulsive device (4) and the piezoelectric switch (5) to turn on the control plate (31) permitting the flowing of gas out of the nozzle (37). As soon as gas flows out of the nozzle (37), it is immediately burned by means of the sparks discharged from the piezoelectric switch (5). Upon turning of the push rod (8), the torque spring (91) thereon is simultaneously squeezed to reserve energy and force the gear driving device (9) to rotate downward. During downward rotation of the gear driving device (9), the V-shaped plate (93) moves through the slant front end of the sliding rod (102) to drive the three upper wheels (61), (62) and (63) and the two lower wheels (71) and (72) to rotate. Because of the effect of torque spring (91) and the rapid return of the sliding rod (102), the push rod (8) and the gear driving device (9) are forced to rapidly rotate backward to original position. When the clip (20) is opened to clamp on one&#39;s clothing, the pressure plate (32) is turned inward to simultaneously turn the shielding plate (33) to block up the piezoelectric switch (5) from the nozzle (37) and close up the flame hole (12). Under this condition, erroneous triggering of the push rod (8) does not make flame. 
     For amusement only, the regulating knob (361) of the regulating ring (36) is turned to off position. When the regulating ring (36) is turned to off position, the turning of the push rod drives the wheels (61), (62), (63), (71) and (72) to rotate but does not produce flame. When the amusement lighter is in wear, the slant show window (21) is exposed outside for the showing of the inner wheels.
