lOS5978 DESCRIPTION OF THE PREFERRED EMBODIMENT
The amusement device of the present invention, as illustrated in Figure 1, consists of a casing 10 provided on the top thereof with a thin sheet 12, il.e., the playing surface, within which a racing path 14 is defined along which a body, i.e., the vehicle 16 provided on the bottom thereof with a magnet, races. Control knobs 17 and 18 protrude upwardly through openings provided in the casing 10. A timing control knob 20, "on-off" switch 22, and a button 24 for determining the length of time allotted each player also protrude upwardly through "
openings provided in the casing 10. The game is played by selecting the playing time to be allocated the player and then operating the control knobs 17 and 18 to steer the vehicle 16 around the path 14. Upon expiration of the time periods, an audible sound is produced signalling end of the game, after which it is impossible to continue operating the knobs 17 and 18.
The mechanism for guiding the vehicle 16 along the path 14 is illustrated in Figures 2 and 3 wherein it will be apparent that within the casing 10 and below the sheet 12 there is provided a magnet 26 which is held within the top portion of the casing 28. An arm 30 extends through the casing 28 and terminates at each en~ thereof in a gear wheel 32 having teeth which mesh with a continuous rack of teeth 34 formed on the side of the casing 10. In similar manner, a rod 36 extends through the casing 28 and terminates at each end in a gear wheel 38 having teeth which mesh with a rack of teeth 40 provided on other of the sides of the casing 10. As seen in lOS5978 Figures 2 and 4, a flexible strip 42 provided with a continuous rack of teeth 44 is attached at one end to the shaft 30 and appropriated mounted within a channel 46 provided in the casing 10. In similar manner, a flexible strip 50 provided with a continuous rack of teeth 52 is positioned within a channel 54 provided in the casing 10, and one end of the flexible strip 50 is attached to the shaft 36. From Figures 4 and 12, it will be apparent that the control knob 18, which is mounted . to the shaft 37 which is spring biased upwardly, is provided near the mid portion thereof with a gear 56 which meshes with a gear 58 which is appropriately mounted with fastener 60 to the casing 10 to rotate. In this manner, as the control knob-18 is manually rotated the gear wheel 56 rotates meshing with the gear 58 which rotates such that the teeth thereof mesh with the continuous rack of teeth 44 provided on the flexible . ¦ strip 42 causing the gear wheels 32 and the rod 30 to move along : the racks of teeth 34. In similar manner, the control knob 17 is provided near the mid portion thereof with a gear 62 having teeth which mesh with the teeth 52 of the flexible strip 50 such that rotation of the control knob 17 moves the flexible strip 50 within its channel 54, the result of which is to cause the gear wheels 38 and the rod 36 to move along the racks of teeth 40.
From the foregoing, it will be apparent that it is possible by manually rotating the control knobs 17 and 18 to move the magnet 26 longitudinally and transversely of the playing surface 12 resulting in a composite oblique movement when the control knobs 17 and 18 are operated simultaneously.
As seen in Figure 3, the housing 28 is provided with slots 27 through which the rod 30 extends and slots 29 through which the rod 36 extends. Thus, the housing 28 and magnet 26 are free to slide along the rods 30 and 36 since the rod 30 is positioned above the rod 36. As previously explained, the vehicle 16 is provided on the bottom side thereof with a magnet 19, as illustrated in Figure 13, thus causing the magnet 26 to attract the vehicle 16 through the thin strip 12 such that operation of the control knobs 17 and 18 permits the player to guide the vehicle 16 along the racing path 14.
As illustrated in Figure 5, the timing control knob 20 is mounted to a shaft 64 which is appropriately journalled within the walls of the casing 10 for rotation. Affixed to the shaft 64 is a gear 66, and a coil spring 68 is wound-around the shaft 64 having one end thereof attached to the shaft 64 and the other end 70 thereof attached to a plate 72 which, as illustrated in Figure 6, is mounted to the walls of the casing 10. It will be apparent, therefore, that rotation of the knob 20 stores energy in the coil spring 68 as it becomes wound around the shaft 64, the purpose of which will be described hereinafter. A plate 74 is also mounted about the shaft 64, as seen in Figure 5, and is provided with two separate cam surfaces 76 and 78, as illustrated in Figures 7-9.
Turning now to Figures 7-9, it will be apparent that a blocking member 80 is mounted for sliding movement with respect l ~o the casing 10, and the button 24 illustrated in Figure 1 is 30 ¦ formed as a part of the blocking member 80 and extends upwardly l through an opening provided in the top wall of the casing ¦ 10. Thus, by moving the button 24 sideways it is possible to ~ . ..

orient the blocking member 80 in three separate positions as illustrated in Figures 7, 8 and 9, respectively. It will be apparent that when the button 24 is positioned all the way to the left, it is possible by rotating the timing control knob 2Q clockwise to move the plate 74 associated therewith to the position illustrated in Figure 7. Movement of the button 24 one step to the right results in movement of the blocking member 80 to the position illustrated in Figure 8 wherein it : will be apparent that the clockwise rotation of the plate 74 is terminated as the cam-like surface 76 strikes the blocking member 80. Movement of the button 24 all the way to the right results in moving the blocking member 80 to the position illustrated in Figure 9 where it will be apparent that clockwise .
. rotation of the plate 74 is stopped as the cam-like surface 78 strikes the blocking member 80. From the foregoing, it will be apparent that by movement of the button 24 between the three separate positions specified above, it is possible to terminate the manual rotation of the timing control knob 20 in the three separate positioned illustrated in Figures 7, 8 and 9, the result of which is to decrease in sequential manner the amount of time that it takes for the control knob 20 and the plate 74 associated therewith to unwind under the influence of the coiled spring 68, as explained hereinafter.
With reference to Figures 5 and 6, it can be seen that the gear 66 meshes with a gear 82 which is formed as an integral part of a larger gear 84 which is secured to a shaft 86 which is appropriately journalled within the walls of the casing 10. .
The gear 84 in similar manner meshes with a gear 88 which is formed as a part of a larger gear 90 which is mounted to a shaft 92 which is appropriately journalled for rotation to the walls of the casing 10. The gear 90 meshes with a gear 94 l which is formed on the underneath side of a larger wheel 96 5 ¦ which is provided along the periphery thereof with a plurality of exaggerated teeth 98. An arm designated by the reference numeral 100 is attached to a shaft 101 which is appropriately journalled for rotation to the walls of the casing 10 such that the arm 100 is free to rotate about the axis of the shaft 102. The arm 100 is provided with fingers 102 which are spaced apart from each other a distance such that rotation of the wheel 96 causes the teeth 98 extending outwardly therefrom on opposite sides of the wheel 96 to sequentially strike opposite of the fingers 102 which causes a clicking sound while the lS arm continuously rotates back and forth. That is, as the wheel 96 rotates one of the teeth 98 on one side of the wheel 96 strikes one of the fingers 102 causing the arm 100 to rotate slightly in one direction and immediately thereafter one of the teeth 98 on the opposite side of the wheel 96 strikes the oppositely disposed finger 102 causing the arm 100 to rotate in the opposite direction, the cumulative effect thereof being a continuous process of engagement and disengagement between the rotating teeth 98 and the fingers 102 which is responsible for the causing the audible clicking sound.
There is also provided an arm 104 which is mounted to an inner wall 106 of the casing 10 to rotate about a shaft 108, as illustrated in Figure 10. The arm 104 is provided with an abutment 110 which extends downwardly through an opening provided in the wall 106 into the vicinity of a post 112 which ~1 1055978 is provided on one of the fingers 102 of the arm 100. The button 22 illustrated in Figure 1 extends upwardly from the arm 104, such that as the button 22 is moved forwardly the arm 104 rotates about the shaft 108 causing the abutment 110 to strike the post 112 urging the finger 102 associated therewith into jamming relationship against adjacent of the exaggerated teeth 98 formed on the wheel 96, the result of which is to prevent the wheel 96 from rotating. It will be apparent, therefore, that moving the button 22 forwardly stops rotation of the wheel 96 and the gears 66, 84 and 90. From the foregoing it will be apparent that after the control knob 20 is rotated clockwise to a starting position determined by the setting of the button 24, operation of the gearing mechanism in response to the uncoiling of the spring 68 causes the control knob 20 to rotate counterclockwise during which time a clicking sound is heard unless the button 22 is moved forwardly to stop the afore-. mentioned movement.
Turning now to Figure 4, the reference numeral 114 designates a slide mechanism which is appropriately mounted for movement along the casing 10. The slide mechanism 114 is provided with an abutment 116 around which one end of a spring 118 is attached, the other end of the spring 118 being secured to an abutment 120 which is formed as a part of the casing 10. Thus, the spring 118 normally urges the slide mechanism 114 to the right. The slide mechanism 114 is provided at one end thereof with a tooth 122, such that when the slide mechanism 114 is moved to the left the tooth 122 is jammed into .
position against adjacent of the teeth formed on the gear 58 the result of which is to prevent the control knob 18 from being operated. In similar manner, a tooth 124 is provided at , the other end of the slide mechanism 114 on the underneath ¦ surface thereof, such that as the slide mechanism is moved to the left the tooth 124 jams adjacent of the teeth of the gear 62 precluding the other control knob 17 from being operated.
, Movement of the slide mechanism to the left, therefore, prevents the player from moving the control knobs 17 and 18 to guide the vehicle 16 along the path 14 after the game is terminated.
As illustrated in Figures 4 and 9, the plate 74 which is mounted with the control knob 20 to the shaft 64 is provided with an , outstanding arm 126 which during the unwinding of the coil spring 68 moves in a counterclockwise direction along with the control knob 20 until the end of the cycle when it engages the surface 128 which is positioned inwardly within the slide ¦ mechanism 114, it being apparent that further counterclockwise movement of the outstanding arm 126 against the surface''128 causes the slide mechanism 114 to move to the left aagainst the surface 128 causing the slide mechanism 114 to move to the "
left against the force of the spring 118 abruptly terminating the ability of the control knobs 17 and 18 to be operated.
As illustrated in Figures 2 and 11, there is also provide a sound producing mechanism in 'the form of a bell 130 appropriately mounted to the casing 10, and a flexible strip 132 provided with a striking element 134 which is mounted to the casing 10 with a fastener 136. It will also be apparent from Figures 9 and 11 that the plate 74 which is mounted along with the control knob 20 to the shaft 64 is provided with an out-standing abutment 138. Thus, as the timing control knob 20 -12- ~

reaches the end of its counterclockwise movement the abutment 138 engages the free end of the strip 132 moving same to the position illustrated in dotted lines in Figure 11 until disengagement occurs, at which time the strip 132 moves backwardly to its original position at which time the element 134 strikes the bell 130 signalling the end of the game period.
