The racing course 4 has a structure in which the inner peripheral course 4a and the outer peripheral course 4b intersect with each other. Regardless of the starting position, the race course 4a and 4b travels to reach the original start point. It is like this. In this embodiment, two sets of a controller 1 and a car 2 are prepared. Normally, two cars 2 are set at the start position to start a race, and a goal of one or several laps is competed. Are playing. When playing alone, one vehicle 2 is automatically driven by the lock switch 14 and the other vehicle 2 is controlled to run.

Before describing the racing mat 3 in detail, the structure of the controller 1 and the drive mechanism of the automobile 2 will be briefly described.

FIG. 5 is an exploded perspective view of the controller 1. As shown in FIG. 5, the controller includes a main body 15 having a battery box 15a and an upper lid 16, and a control circuit is incorporated therein. The board 17 and various switches are housed therein. The low-speed traveling switch 12 is composed of a switch body 18 attached to the front side of the board 17 and a push button 19. The push button 19 is composed of a push button portion 20 and a mounting base portion 21, is swingably attached to a boss 22 inside the controller 1 at an end portion 21 a of the mounting base portion 21, and is externally attached at the push button portion 20 portion. Exposed. Further, a tongue piece 21b is formed on the opposite side of the end portion 21a of the mounting base portion 21, and the lock switch 14 is engaged with this tongue piece 21b. Similarly, the high-speed running switch 13 is composed of a switch body 23 and a push button 24 mounted on the back side of the board 17, and the push button 24 is composed of a push button portion 25 and a mounting portion 26. .

The lock switch 14 is slidably attached to the upper lid 16 and is engaged with the low speed traveling switch 12 on the lower surface. A linear cam 14a is formed on the lower surface of the lock switch 14, and the linear cam 14a engages with the tongue piece 21b of the low speed traveling switch 12. That is, by sliding the lock switch 14 to the lock position, the low speed traveling switch 12 is turned on, and the automobile 2 is automatically driven at a low speed. The transmitting antenna 11 is held so as to be sandwiched between the main body 15 and the upper lid 16, and is connected to the control circuit of the board 17.

Here, a method of operating the controller 1 will be described. When the automobile 2 is driven by the racing course 4, first, the main switch 36 of the automobile 2 is turned on and the mode changeover switch 37 is switched to the course mode. In this state, when the low speed traveling switch 12 is turned on, the vehicle 2 travels forward on the racing course 4 at low speed, and when the high speed traveling switch 13 is turned on, it travels forward at high speed. When both switches 12 and 13 are turned on at the same time, the high speed traveling switch 13 is prioritized and the automobile 2 travels forward at high speed. Therefore, in the actual running, the high-speed running switch 13 is turned on and off while the low-speed running switch 12 is turned on so as to correspond to the straight line portion and the curved portion of the racing course 4 to change the speed of the automobile 2. To control.

On the other hand, when driving the automobile 2 outside the racing course 4, first, the main switch 36 of the automobile 2 is turned on, and the mode changeover switch 37 is switched to the mode outside the course. In this state, when the low speed traveling switch 12 is turned on, the vehicle 2 travels forward at a low speed, and when the high speed traveling switch 13 is turned on, the vehicle turns back to the left. When both switches 12 and 13 are turned on at the same time, the high-speed running switch 13 is prioritized and the automobile 2 turns back to the left. Therefore, the low-speed traveling switch 12 and the high-speed traveling switch 13 can be properly used to drive the vehicle 2 off the course while avoiding obstacles and the like.

Next, the drive mechanism of the automobile 2 will be described with reference to FIG. Since the lower left part is the front part of the vehicle body 31 and the upper right part is the rear part with respect to the paper surface of the figure, the left and right expressions are the same as the vehicle body 31 in the following description, which is the opposite of the left and right paper surfaces. FIG. 6 is an exploded perspective view of the drive mechanism around the rear wheel 33. As shown in FIG. 6, the drive mechanism includes a drive motor 41, a clutch gear portion 42, a reduction gear portion 43, a high / low speed shift gear portion 44, and a power source. The transmission gear unit 45, the differential gear unit 46, and the engine sound generating unit 47 are included. The drive motor 41 is normally and reversely rotated at a constant speed by a drive circuit using a battery (not shown) housed in the above-mentioned battery box 38 as a power source, and the rotational power is transmitted from the pinion 51 to the clutch gear portion 42. .

The clutch gear portion 42 includes an input gear 52 meshing with the pinion 51, an output gear 53, a clutch 54, and a coil spring 55 meshing with the clutch 54 via the output gear 53. It is configured by being installed coaxially. The input gear 52 and the driving side 54a of the clutch 54 are fixed to the rotating shaft 56, while the output gear 53 and the driven side 54b of the clutch 54 are mounted on the rotating shaft 56 in a freely rotating state. Therefore, the rotation of the input gear 52 is transmitted from the output gear 53 to the reduction gear portion 43 via the main driving side 54a and the driven side 54b of the clutch 54. In this case, the driven side 54b of the clutch 54 is urged by the coil spring 55 to the main driving side 54a of the clutch 54 via the output gear 53, and normally both the main driven side 54a and 54b rotate together, but the output gear 53 Is overloaded, the driven side 54b of the clutch 54 slides so that the direct drive motor 41 is not overloaded.

The reduction gear unit 43 is configured to be fixed to the rotary shaft 60 in a state where the three gears of the large gear 57, the middle gear 58, and the small gear 59 are in contact with each other. The large gear 57 meshes with the output gear 53 of the clutch gear portion 42 and serves as an input end for power, and the middle gear 58 serves as an output end for transmitting power to the high / low speed shift gear portion 44 during high speed traveling, thus serving as a small gear. Reference numeral 59 is an output end for transmitting power to the high / low speed shift gear portion 44 during low speed traveling. That is, the large gear 57, the middle gear 58, and the small gear 59 rotate integrally with each other, but due to the difference in the number of teeth of the middle gear 58 and the small gear 59, high speed traveling and low speed traveling are possible.

The high / low speed shift gear portion 44 includes a rotary arm 61 rotatably attached to an end portion of the rotary shaft 56 of the reduction gear portion 43, and a pair of shaft protrusions 62, 62 formed on the rotary arm 61. Each of them is composed of a high speed gear 63 and a low speed gear 64 which are rotatably supported. The high speed gear 63 meshes with the middle gear 58 of the reduction gear unit 43, and the low speed gear 64 meshes with the small gear 59 of the reduction gear unit 43. That is, in this portion, the middle gear 58 is the sun gear, the high speed gear 63 is the planetary gear, the high speed planetary gear train having the rotating arm 61 as the carrier, the small gear 59 as the sun gear, and the low speed gear 64 as the planetary gear. A low-speed planetary gear train having gears and a rotating arm 61 as a carrier is configured.

In this case, when the drive motor 41 rotates in the normal direction, the low speed gear 64 is revolved clockwise around the small gear 59 as viewed from the rotary arm 61 side so as to mesh with the transmission gear 65 of the power transmission gear portion 45. It has become. On the other hand, when the drive motor 41 rotates in the reverse direction, the high-speed gear 63 revolves counterclockwise around the middle gear 58 when viewed from the rotary arm 61 side, and directly meshes with the main gear 67 of the differential gear portion 46. That is, the transmission gear 65 of the power transmission gear portion 45 is fixed to the rotation shaft 66 thereof, and the main gear 67 of the differential gear portion 46 is rotatably attached to the rear axle 68, respectively. When the drive motor 41 is in the normal rotation, the rotational power from the low speed gear 64 is input to the main gear 67 via the transmission gear 65 and the reverse rotation of the middle gear 58 and the small gear 59 is performed. At this time, the rotational power from the high speed gear 63 is directly input to the main gear 67. With this structure, the forward and reverse rotations of the drive motor 41 are converted into low and high speed rotations and transmitted in the main gear 67 portion (see FIG. 7).

On the other hand, the operation end 37a of the mode changeover switch 37 comes into contact with and separates from the end 61a of the rotary arm 61. When the course mode is changed over, the mode changeover switch 37 is operated. The operating end 37a and the end 61a of the rotary arm 61 are separated from each other, and when the mode is switched to the off-course mode, both the end 61a and the operating end 37a are engaged. In this separated state, the dynamic force transmission path is as described above, but in the engaged state, the rotation of the rotary arm 61 is locked while the low speed gear 64 and the transmission gear 65 mesh with each other, and the drive motor 41 Both the normal and reverse rotational powers are transmitted to the differential gear section 46 via the power rotary gear section 45 as they are in the normal and reverse rotation. Therefore, two normal and reverse rotation patterns of the drive motor 41 that constitutes the drive source are converted into two traveling patterns of high speed and low speed in the course mode, and two traveling patterns of forward (low speed) and backward in the out-of-course mode. Is converted to. In the reverse running pattern, the axle 40 of the front wheel 32 on the right side has a long groove (see FIG. 4). Therefore, the axle of the front wheel 32 is actually tilted to the left due to road resistance. To be done.

The differential gear section 46 includes a main gear 67 which is an input end of power, a pair of small pinions 69 and 69 incorporated in the main gear 67, and a left side gear 70 and a left side gear 70 which mesh with the small pinions 69 and 69 from both sides. And a right side gear 71. The left rear wheel 33 and the left side gear 70 are fixed to the rear axle 68, and the right rear wheel 33, the right side gear 71 and the main gear 67 are rotatably supported by the rear axle 68. The rotational power input to the main gear 67 is transmitted to both side gears 70, 71, the left side gear 70 side is transmitted to the left rear wheel 33 via the rear axle 68, and the right side gear 71 side is connected to the right side via the joint 72. It is transmitted to the rear wheel 33. In this case, the main gear 67, the both small pinions 69, 69 and the both side gears 70, 71 constitute a differential gear train, and the left and right rear wheels 33, 33 are provided with a differential, so that the vehicle 2 can be turned. It can be done easily.

The engine sound generating section 47 is driven by the drive gear 73 and the ratchet wheel 74 rotatably supported on the rear axle 68 between the left rear wheel 33 and the left side gear 70, and the ratchet wheel 74. The leaf spring 75 thus oscillates, and the drum 76 struck by the upper end bent portion 75a of the leaf spring 75 oscillates. The drive gear 73 and the ratchet wheel 74 are fixed to each other so as to rotate together. The leaf spring 75 is fixed to the frame 77 to which the drum 76 is attached, the tip end 75b engages with the ratchet wheel 74, and the upper end bent portion 75a faces the striking surface of the drum 76 with a gap. . The striking surface of the drum 76 is made of rubber or the like, and when the leaf spring 75 repelled by the ratchet wheel 74 continuously strikes, a sound similar to the engine sound is produced.

The rotational power to the engine sound generating section 47 is input from the transmission gear 65 of the power transmission gear section 45. In this case, the low speed traveling in the course mode and the forward and back turn traveling in the out-of-course mode are performed. In this case, power is transmitted from the low speed gear 64 of the high / low speed shift gear section 44 to the drive gear 73 via the transmission gear 65, and during high speed running in the course mode, from the high speed gear 63 of the high / low speed shift gear section 44 to the main gear 67. The power is transmitted to the driving gear 73 via. As a result, the rotation of the ratchet wheel 74 becomes slower when the vehicle 2 travels at a low speed, and the rotation of the ratchet wheel 74 becomes faster when the vehicle 2 travels at a higher speed, thereby generating an engine sound corresponding to the speed of the vehicle 2. You can

Reference numeral 78 in FIG. 6 is a drive circuit board, and a drive circuit for driving the drive motor 41 in the forward and reverse directions based on a control signal from the controller 1 is incorporated in the drive circuit board 78. There is. Also, in the figure, what is shown next to the drive circuit board 78 is a main switch 36 for turning the drive circuit on and off, and the main switch 36 includes a slide button 36a exposed on the surface of the vehicle body. It is composed of a switch body 36b.

Next, the racing mat 3 will be described with reference to FIGS. 3, 8 and 9. The racing mat 3 includes two long and short track rails 81 and 82 laid at the center of each of the inner and outer courses 4a and 4b, and both track rails 81 and 82 on the surface 3a of the racing mat 3 at appropriate intervals.

Therefore, the race course 4 having a desired shape is completed by sequentially inserting the track rails 81 and 82 into the fixing member 83. As shown in FIG. 9, the cross rail 84 is composed of four rail guides 85, 85, 85, 85 forming the intersection of the track rails 81, 82, and a holding plate 86 for holding the rail guide 85. The inner and outer track rails 81 and 82 are cross-connected to each other by inserting both ends of the inner and outer track rails 81 and 82 into the rail guides 85, 85, 85 and 85, respectively.

On the other hand, the vehicle 2 engages with both inner and outer track rails 81 and 82 at the portion of the guide member 39 on the lower surface of the vehicle body 31, and travels with both inner and outer track rails 81 and 82 as guides. At that time, although the front wheels 32, 32 are not particularly steered, they are automatically steered by the car bearing 40 having the long groove described above (see FIG. 4). Then, in the racing course 4 described above, the automobile 2 starting from the inner peripheral course 4a goes around the inner peripheral course 4a, then goes to the outer peripheral course 4b at the intersection, and completes the outer peripheral course 4b. After passing through the intersection again, it makes a half turn around the inner course 4a and returns to the original start (goal position). On the other hand, the car 2 starting from the outer peripheral course 4b enters the inner peripheral course 4a at the intersection after making a half-lap around the outer course 4b, completes one round of the inner course 4a, and then makes another half-lap around the outer course 4b via the intersection. Then return to the original start position (goal position). Therefore, various car races using two automobiles 2 are possible.

As described above, according to the present embodiment, the car 2 can be set on the track rails 81 and 82, and the car 2 can be run by the controller 1 to perform the car race on the racing mat 3. In this case, the racing mat 3 has the track rails 81 and 82 and the cross rail 84 which are attachable / detachable and made of a soft material, so that it can be extremely compacted by rolling or bending.
