Description

Description: TECHNICAL FIELD The present invention relates to a device that allows a traveling body to move straight or obliquely on a groove plate having a plurality of guide grooves formed therein.

(Prior Art) There is, for example, a horse racing game in which a running body is placed on a groove plate and is made to run straight or obliquely.
In this horse racing game, a toy racehorse is placed on a track-free running surface, and a running body is provided below the running surface. Then, the running body is moved while magnetically attracting the racehorse and the running body.

In the conventional horse racing game apparatus, the drive wheels provided on the traveling body are steered directly by radio control.

(Problems to be Solved by the Present Invention) As described above, in the related art, since the traveling direction of the traveling body is controlled by radio control or the like, its control mechanism becomes expensive and its reliability is somewhat high. There was also the problem of chipping.

An object of the present invention is to provide an apparatus capable of controlling the direction of a traveling body with a mechanical structure.

(Means for Solving the Problem) The present invention is provided with a plurality of guide grooves that are elongated in the traveling direction, a groove plate in which the guide grooves are parallel to each other, and a traveling body that travels on the groove plates. , This running body
A drive wheel for moving it in a straight direction and a pair of sprockets for engaging the guide groove and moving the traveling body in the direction parallel to the guide groove are mounted on the main body, and the drive wheel has a circumferential direction. And each of the divided wheels are movable in the axial direction, and a guide mechanism for positioning the divided wheels at the axial center immediately before the divided wheels come into contact with the groove plate is provided. Is characterized in that it is configured to be driven by a motor.

(Operation of the present invention) Since the present invention is configured as described above, when the sprocket is rotated, the traveling body moves laterally on the groove plate so as to walk across the guide groove.

In the following, the direction that crosses the guide groove is called the X direction,
The guide groove direction is called the Y direction. As described above, the moving body is X
When moving in the direction, the split wheel, which is in contact with the groove plate, moves relative to the main body in the axial direction.

Therefore, the traveling body moves in both the X and Y directions at the same time, and the traveling body at this time moves in an oblique direction in which the velocity component in the X direction and the velocity component in the Y direction are combined.

Then, as described above, the split wheel that relatively moved with the main body is returned to the axial center position of the main body by the guide mechanism after it is separated from the groove plate, and it is grounded again. It is always located in the axial center.

(Embodiment of the present invention) The main body 1 of the traveling body a has standing walls 2 and 3 formed in front and rear thereof, and sprockets 4 and 5 are provided on the outer sides of the standing walls 2 and 3. The sprockets 4 and 5 rotate integrally via a rotary shaft 6, and the rotary shaft 6 is linked to the first electric motor m ₁ . The pitch of the teeth 4a and 5a of the sprockets 4 and 5 thus configured is made equal to the pitch of the guide grooves 8 formed in the groove plate 7 so that the teeth 4a and 5a can be rotated while being engaged with the guide grooves 8. .

In the main body 1 as described above, a pair of side plates 9 and 10 is provided on the front side where the sprocket 4 is provided. The side plates 9 and 10 are provided with a pair of rotary plates 12 and 13 rotatably spanning a plurality of support shafts 11 and are rotatable.
The second electric motor m ₂ is made to rotate 12 and 13.

A drive wheel 14 is provided on the support shaft 11, and the drive wheel 14 is divided into two parts from the diameter line of the drive wheel 14.
It is a and 14b. The split wheels 14a and 14b are provided on the support shaft 11
Is slidable in the axial direction with respect to the rotary plate
12 and 13 are designed to rotate integrally.

For each of the split wheels 14a and 14b as described above,
Friction bodies 15a, 15b made of rubber or the like are provided in the circumferential direction, and cam portions 16a, 16b are formed on both sides of the friction bodies 15a, 15b at a position lower than that. The cam portions 16a and 16b are rotated in the rotational direction 17 shown in FIG.
Towards the side, the width is gradually narrowed into a wedge shape.

The width of the friction bodies 15a and 15b is made larger than the groove width of the guide groove 8 so that the friction body does not fall into the guide groove 8.

Then, the side plates 9 and 10 fixed to the main body 1 are provided with position correcting members 18 and 19 with a constant facing interval, and the distance between the tips of the position correcting members 18 and 19 is When the maximum width portions of the cam portions 16a, 16b are made substantially equal to each other and the maximum width portions of the cam portions 16a, 16b come into contact with the position correcting members 18, 19, these split wheels 14a, 14b cause the shafts of the support shaft 11 to move. It is located at the center of the direction.

Moreover, when the maximum width portions of the cam portions 16a and 16b are in contact with the position correcting members 18 and 19 as described above, the split wheels 14a and 14b are set to be immediately before contacting the thin plate 7.

For example, when each of the split wheels 14a and 14b is at the position shown in FIGS. 5 to 7, one split wheel 14a is grounded and the other split wheel 14b is separated from the thin plate 7. Then, at this time, of the cam portion 16b of the other split wheel 14b,
The narrowest part faces between the position correcting members 18 and 19. When the drive wheel 14 is rotated from this state to the positions shown in FIGS. 8 to 10, the width of the cam portion 16b of the other split wheel 14b facing between the position correcting members 18 and 19 is gradually increased, and that portion is changed. The split wheels 14b are pushed by the position correcting members 18 and 19 and are pushed toward the axial center side.

Then, when the other split wheel 14b enters the state of FIGS. 11 to 13 immediately before it comes into contact with the groove plate 7, the other split wheel 14b.
Since the maximum width portion of the cam portion 16b of 14b comes into contact with the position correcting members 18 and 19, the other split wheel 14b is located at the axial center of the support shaft 11 immediately before it comes into contact with the groove plate 7. .

The cam portions 16a and 16b and the position correcting members 18 and 19 form the guide mechanism of the present invention.

In addition, a slide protrusion 21 is formed on the rear side of the rear surface of the main body 1, and the slide protrusion 21 and the drive wheel 14 contact the groove plate 7 so that the other portions of the main body 1 are separated from the groove plate 7. In addition to being lifted, the bottoms of the tooth spaces of the sprockets 4 and 5 are also lifted from the groove plate 7. The reason why only the drive wheels 14 and the slide projections 21 are in contact with the groove plate 7 is to reduce the contact friction between the main body 1 and the groove plate 7.

Then, the traveling pair a is placed on the groove plate 7, and the teeth 4a and 5a of the sprockets 4 and 5 are engaged with the guide groove 8. In this state, the second electric motor m ₂ is driven to drive the driving wheels 14
When is rotated, the driving force causes the traveling body a to move in the direction of arrow 20 in FIG. At this time, the teeth 4a, 5a of the sprockets 4, 5
Since the engagement between the guide groove 8 and the guide groove 8 functions as a guide, the traveling body a moves along the guide groove 8.

When, for example, the sprockets 4 and 5 are rotated from the above state, the traveling body a moves laterally as if it walks over the guide groove 8. At this time, for example, the split wheel 14a that is in contact with the groove plate 7 moves axially relative to the main body 1.

Therefore, the traveling body a skews in a direction in which the X-direction speed component of the sprockets 4 and 5 and the Y-direction speed component of the drive wheels 14 are combined.

In this way, the split wheel 14a relatively moved in the axial direction.
After returning from the groove plate 7, the cam portion 16a returns to the axial center position again while contacting the position correcting members 18 and 19.

As described above, the reason why the split wheel is returned to the axial center position immediately before it comes into contact with the groove plate 7 is to allow the traveling body a to skew in either the left or right direction. .

As is apparent from the above description, this device can freely control the traveling body a to be straight or oblique by controlling the _first and second electric motors m ₁ and m ₂ . Therefore, this device can be applied to any device as long as it allows the traveling body a to travel on the groove plate 7 having a large number of guide grooves 8.

For example, a horse racing game can be considered as one application example of this device. In this horse racing game, a horse model is placed on a trackless running surface, a groove plate 7 is provided under the running surface, and a running body a is placed on the groove plate 7. Then, the running body a is moved while magnetically attracting the racehorse model and the running body a. In this way, since the model follows the traveling direction of the traveling body a, the model on the traveling surface appears to be moving freely without being restricted by the trajectory.

Further, in this device, Y which is the direction of the guide groove of the traveling body a.
Since the movement in the direction is restricted by the sprockets 4 and 5 and the guide groove 8, the traveling body a can be moved along the guide groove 8 regardless of the control system. For example, if the groove plate 7 is S-shaped and the guide groove 8 is formed along it, the traveling body a can travel along the S-shape regardless of the control system.

Moreover, when the traveling body a is slanted, it is sufficient to control the rotation of the sprockets 4 and 5 as described above, so that the control system is simple.

Further, if the guide groove 8 is formed in an S shape as described above and the traveling body a is made to travel there, and the sprockets 4 and 5 are rotated in the process, the traveling body a is traveling in an S shape. , It is possible to draw a very complicated running pattern of going diagonally.

The groove plate 7 of this embodiment may have various shapes other than the S-shape, and may have a shape according to the purpose.

(Effect of the present invention) According to the device of the present invention, the traveling body on the groove plate can be freely controlled to move straight or obliquely. Moreover, since it has a mechanical structure, it is inexpensive and highly reliable.

Further, according to this device, since the movement of the traveling body in the Y direction, which is the guide groove direction, is restricted by the pair of sprockets and the guide groove, the control in the Y direction only needs to depend on the guide groove. No special control system is required.

Moreover, when the traveling body is slanted, it is sufficient to control the rotation of the sprocket as described above, so that the control system is simple.

Furthermore, if the groove plate is bent into an S-shape, it is possible for the traveling body to travel along the curved line and further skew, which makes it possible to perform extremely complicated traveling as a whole. is there.
