Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a remotely controlled traveling toy that allows the direction of the traveling toy to be easily changed in a narrow space.

Traveling toys are one of the most popular toys among many toys, and in particular, traveling toys that can be operated in various ways by remote control are popular not only among children but also among adults. However, in this type of conventional traveling toy, a wide running radius is required when changing the direction of the traveling toy.
If you run it in a small room or on a tabletop, it will immediately collide with a wall or fall off the tabletop, making it impossible to enjoy playing in these places.

The present invention was made in view of the above circumstances, and
By providing left and right drive wheels and gear groups for the drive wheels independently, and by rotating the left and right drive wheels in opposite directions, the direction of the traveling toy can be changed in extremely narrow spaces. The purpose is to provide a remotely controlled traveling toy that can be played happily in a room or on a tabletop.

Further, the present invention provides a remotely controlled running toy that allows the user to play by spinning the running toy, and also allows for various types of play, such as a game of competing with reflexes to stop the running toy in a predetermined direction. With the goal.

In order to achieve the above object, the present invention provides a remote-controlled traveling toy that is operated by remote control or the like and travels on four wheels with left and right front wheels and left and right rear wheels serving as driving wheels. A forward/reverse motor, a heavy object such as a battery are positioned above or behind the left and right rear wheels, and an auxiliary wheel for wheelie running is supported at the rear position of the rear wheels, (b) the rear wheels that become the drive wheels are (c) The forward and reverse motors have drive shafts protruding from each side in the axial direction of the vehicle body, and a drive shaft for the left drive wheel that transmits driving force between each of these drive shafts and the left and right drive wheels, respectively. A gear group and a gear group for the right drive wheel are provided independently, and (d) rotation of the motor drive shaft in two different directions is always applied to one of the gear groups for the left and right drive wheels, while rotation of the drive wheel in the same direction is always applied to either one of the gear groups for the left and right drive wheels. The configuration includes an idler gear that transmits the signal as follows.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

Fig. 1 is an overall perspective view of the running toy according to the embodiment, Fig. 2 is an exploded perspective view of the main parts, Fig. 3 is an enlarged plan view of the main parts, Fig. 4 is an explanatory diagram of the operation of the left gear group, and Fig. 5 is the right side. FIG. 6 is an explanatory diagram of the operation of the gear group, and FIG. 6 is an explanatory diagram of the direction change state of the traveling toy.

In these drawings, 10 is a vehicle body, 20 is a chassis base, 30 is a left and right side plate, 40 is a motor, and 50 is a
60 is a left drive section, and 60 is a right drive section.

The vehicle body 10 of the traveling toy is formed to imitate a passenger car. The chassis base 20 is provided with a mounting part 22 in the front part on which the printed circuit board 21 is mounted tilted forward, a motor storage part 23 in which the motor 40 is stored in the rear part, and a rechargeable motor 40 in the rear part. A battery storage section 24 for storing a battery 41 is provided. These are formed integrally with the chassis base 20 and tilted forward. 25 is a printed circuit board 21
A light emitting diode connected to the vehicle body 10 is fixed to the inside of the front part of the vehicle body 10 in order to light up the headlight 11 of the vehicle body 10.

The left and right side plates 30 are assembled on both the left and right sides of the chassis base 20, and include holding pieces 31 that press and fix both side edges of the printed circuit board 21, and a drive unit 5.
A gear box portion 32 is formed to cover and protect the gears 0 and 60. When the left and right side plates 30 are completely assembled to the chassis base 20, the clamps 32 at the tips of the left and right side plates 30 fit into the vehicle body hooks 34 and are clamped. In this way, the chassis is mounted on the chassis base 20.
It is formed by the left and right side plates 30 and a vehicle body hook 34, and is screwed to a fixing portion (not shown) provided inside the vehicle body 10 with a screw 35 via the vehicle body hook 34. Reference numeral 36 denotes front wheels attached to the left and right side plates 30, respectively.

The left drive unit 50 includes a gear 51, an intermediate gear 52, a large gear 53, and a gear 51 which is rotatably attached to one motor shaft 42 of a forward/reverse motor 40 having motor shafts 42 and 43 protruding from both sides in the width direction of the vehicle body. It is composed of a gear 54, an axle 55 having a large gear 53 pivotally attached to one end, and a drive wheel 56 pivotally attached to the tip of the axle 55 on the outside of the left side plate 30. Of these, the floating gear 54 is provided with an arc-shaped long groove 54a around the rotation center of the gear 51 on the side surface of the chassis base 20 and on the inner wall surface of the gear box 32 of the left side plate 30 (not shown).
It is installed freely here. This floating gear 5
4 is located between the gear 51 and the large gear 53 when the gear 51 rotates in the direction of the arrow A in FIG.
and the intermediate gear 52 and mesh with each other. Therefore, whether the gear 51 rotates in the A direction or the B direction, the large gear 53, that is, the drive wheel 56 always rotates only in the arrow C direction.

The right drive unit 60 includes a gear 61 that is rotatably attached to the other motor shaft 43 of the forward and reverse rotation motor 40, and
1 and an intermediate gear 62 that meshes with the intermediate gear 62.
It is composed of a large gear 63 that meshes with the large gear 63, an axle 65 that pivots the large gear 63 on one end, and a drive wheel 66 that pivots on the other end of the axle 65 on the outside of the right side plate 30. Therefore, when the gear 61 rotates in the direction A, the large gear 63, that is, the drive wheel 66 rotates in the C direction, and when the gear 61 rotates in the B direction, the large gear 63
That is, the drive wheel 66 rotates in the D direction.

Since the left side drive section 50 and the right side drive section 60 are configured as described above, when the forward/reverse rotation motor 40 rotates in the normal direction and its two motor shafts 42 and 43 both rotate in the direction A, the left and right drive wheels 56 and 66 both rotate in the C direction to make the traveling toy go straight. Further, when the rotation direction of the forward/reverse motor 40 is switched and reversed, and the two motor shafts 42 and 43 are both rotated in the B direction, the left drive wheel 56 moves in the C direction, and the right drive wheel 66 moves in the D direction. Each rotates, causing the traveling toy to spin and change direction around its rear as shown in FIG.

Note that 71 is an antenna that receives a signal from a remote control device (not shown). Radio waves, infrared rays, etc. can be used as signals for remote control.
Further, reference numeral 72 denotes an auxiliary wheel for wheelie running that is rotatably supported at the rear of the chassis base 20. Since heavy objects such as the motor 40 and the battery 41 are located at the rear of the running toy, the running toy can be suddenly started or loaded with coins or the like to perform a wheelie.

Since the remotely controlled traveling toy in this embodiment is configured as described above, when the motor 40 is rotated in the forward direction by the remote control device, the traveling toy can be made to move straight, and when the motor 40 is rotated in the reverse direction, the front wheels float. In the upright position, the running toy can change direction and play with spin. Changing direction and spinning a traveling toy can be done in a very small space. Therefore, by repeating forward and reverse rotation, the game can be fully played even in a small room or on a tabletop.

Not limited to the above embodiment, it is of course possible to provide a floating gear in the right drive section to change the direction in which the traveling toy spins. Further, the headlight of the running toy can be made to turn on during the entire operation of the running toy, or only when the running toy is running straight or spinning.

As described above, according to the present invention, heavy objects such as a forward/reverse motor and a battery are positioned above or behind the left and right rear wheels that serve as driving wheels, and an auxiliary wheel for wheelie is supported at a position behind the rear wheels. Therefore, by suddenly starting the traveling toy, etc., the center of gravity is moved rearward, and the auxiliary wheels are brought into contact with the ground with the front wheels lifted up, allowing the user to enjoy wheelie driving.

Further, since the left and right drive wheels are made to rotate independently, and one of the drive wheels is always made to rotate in only one direction, the traveling toy can be made to move straight and spin. Furthermore, since the running toy is spun by rotating the left and right drive wheels in opposite directions, it is possible to do so within an extremely narrow space, and the direction of the running toy can also be changed within a narrow space. Therefore, even in a narrow room or on a tabletop, the player can enjoy playing while preventing collisions and falls.

At this time, since the center of gravity of the traveling toy is at the rear, the front wheels, which are the traveling wheels, float upwards, allowing for smooth spins or direction changes.On the other hand, when driving normally in a straight line, the four wheels It makes contact with the ground and allows stable straight-line driving.

Furthermore, the way a traveling toy changes from normal straight running to spinning with its front wheels floating or changing direction is full of surprises and is highly interesting as a toy.

In addition to enjoying the spin of the running toy itself, it can also be applied to various types of play, such as a game in which players compete on their reflexes to accurately stop the running toy in a predetermined direction.

Further, since the forward/reverse motor has drive shafts protruding from both sides in the vehicle width direction, the shaft and gears for transmitting data from the drive shaft to the right and left drive wheel gear groups can be omitted and simplified.
