Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a running toy, and particularly has two types of modes: a running mode and a running obstruction mode for interfering with the running of other running toys. and a traveling toy with increased usefulness.

(Prior art and its problems) Conventionally, when it comes to toys such as racing cars and remote-controlled cars that are equipped with drive sources such as motors and springs on the car body and run, emphasis has been placed primarily on making them run. Because of this, some people disliked it because it got boring quickly and lacked interest. At most, there were toys that caused racing cars and other cars running adjacent to each other to collide with each other. From this point of view, if a variety of configurations were added in addition to the fun of running, it would be possible to improve the usefulness of toys by increasing their uses and functions. In the case of toys, the power for running and the power for other operations were generally separate. For this reason, an increase in size and cost cannot be avoided.

(Object of the Invention) The present invention solves the above-mentioned problems, and in particular, provides a running toy that can improve functionality and usefulness by having a running obstruction mode for other running toys in addition to the normal running mode. Its purpose is to provide.

(Means for Achieving the Object) In order to achieve the above object, the traveling toy according to the present invention includes a traveling mechanism that drives wheels that are rotatably supported on a vehicle body, and a traveling mechanism that is protrusively provided on the side of the vehicle body. The present invention is characterized by comprising a protruding mechanism of a protruding means for obstructing the running of other running toys.

(Example) Hereinafter, the traveling toy of the present invention will be described in detail.

FIGS. 1a and 1b are perspective views of an embodiment of the present invention,
This traveling toy 1 includes a chassis 2 that is the base of the vehicle body, a motor (drive source) 3 mounted on the chassis 2, and front wheels 4 and rear wheels rotatably supported by the chassis 2. wheel 5, a first gear mechanism 10 that transmits the drive torque from the first output shaft 3a of the motor to the rear wheel 5, and a first gear mechanism 10 that transmits the drive torque from the second output shaft 3b of the motor to the ejecting mechanism 30. It is roughly constructed from two gear mechanisms 20. Note that it is possible to use various driving sources other than the motor, such as a spring. When using a motor, the direction of rotation can be changed by changing the polarity, using a clutch, etc.

As shown in FIGS. 2a and 2b, the first gear mechanism 10 includes a columnar base 11 rotatably supported in two directions on the chassis 2, and a predetermined circumferential interval on the side surface of the base 11. A pair of pinion gears 12a, 12b are rotatably supported on the upper surface of the base 11, and each pinion gear 12a, 12b and a first output shaft 3a (in a gear shape) are rotatably supported on the upper surface of the base 11. and a large gear 13 that constantly meshes with each other. When the first output shaft 3a rotates in the A direction, the crown gear 13 rotates in the C direction,
As shown by the solid line in FIG. 1b, the pinion gear 12a
is meshed with a driven gear 7a coaxially integrated with the tire 6a of the rear wheel 5, and when the output shaft 3a rotates in the direction B, the crown gear 13a rotates in the direction D. As shown by the dotted line, the pinion gear 12b is configured to mesh with a driven gear 7b which is also integrated with the tire 6b of the rear wheel 5. When the first output shaft 3a rotates in the A direction, the rear wheel 5 rotates in the forward direction (or backward direction) shown by the arrow by the pinion gear 12a, and when the first output shaft 3b rotates in the B direction Also rear wheel 5
are rotated in the same forward direction (or backward direction) by pinion gear 12b.

The second gear mechanism 20 is disposed between a pair of partition plates 40 and 41 supported on the chassis 2 in a substantially upright state, as shown in FIG.
As shown in figures a and b, the second output shaft 3b of the motor
Three transmission gears 21, 22, 23 that sequentially transmit driving torque from (gear-shaped) to the ejecting mechanism 30
It is composed of. Note that the number of transmission gears may be at least one. First transmission gear 21
The second transmission gear 22 includes small transmission gears 21a and 22a coaxially integrated with the rotation shaft thereof.
As shown in the figure, the second output shaft 3b has a large-diameter gear portion of the first transmission gear 21, a large-diameter gear portion of the second transmission gear 22 has a small transmission gear 21a, and a third
The transmission gears 23 mesh with the small transmission gears 22a, respectively. As shown in FIG. 3c, a rotating shaft 21b protrudes forward and backward from the center of the first transmission gear 21.
40a is a rotary shaft engagement guide portion (the recess area may be a guide made of a convex strip, etc.) consisting of a curved slit or the like punched out in each partition plate 40;
It is rotatably supported by 41a, and
The partition plate 40 is constantly urged upward (in the torque transmission cutoff release direction) by an elastic means 25 whose one end is supported by a locking portion 24 formed on the wall surface of the partition plate 40 . When the first transmission gear 21 rotates in the E direction, the third transmission gear 23 tries to rotate in the G direction, but the engagement projection 31a is rotated by the stopper 42b via the engagement piece 33a. As a result, the rotation of the transmission gear becomes difficult, and as a result, the rotating shaft 21b tries to move downward (in the torque transmission cutoff direction) against the force of the elastic means 25. Due to the downward displacement of the first transmission gear 21, the engagement between the small transmission gear 21a and the second transmission gear 23 becomes incomplete, so that the driving torque cannot be transmitted to the ejecting mechanism. Becomes incomplete. Even in the torque transmission cutoff state, the first and second transmission gears 2
1 (transmission small gear 21a) and 22, it is convenient to operate the ejecting mechanism described later. In the illustrated embodiment, the torque transmission cutoff release direction is upward;
Although the torque transmission cutoff direction is downward, this may be reversed, or the rotating shaft 21b may be displaced laterally. Further, the torque transmission cutoff section may be provided in another transmission gear.

FIG. 4 shows an example of the ejecting mechanism 30, which includes a rotating plate 31 whose axis is coaxially supported by the rotating shaft 23a of the third gear 23 of the second gear mechanism 20. and an actuating member 33, which serves as a protruding means, is supported by a guide 42a on the front surface of the partition plate 41 so as to be able to reciprocate in the horizontal direction (including diagonally up and down directions), and whose movement limit is defined by a stopper 42b. and the actuating member 33
An engaging protrusion 31a is provided on the outer periphery of the rotary plate 31 to protrude in the outer radial direction. An engaging piece 33a is provided protrudingly. When the second output shaft 3b of the motor rotates in the direction A, the torque transmission cutoff section operates to limit the torque transmission between the first transmission gear 21 and the second transmission gear 22. Torque transmission to gear 23 is reduced. If the restriction by the torque transmission cutoff part is slightly reduced, a small amount of torque transmission will be performed, so that the rotation plate 31 can be moved in the G direction (non-operating direction).
As a result, the actuating member 33 can be pulled back by the engagement protrusion 31a. However, when the engagement protrusion 31a rotates to a position where it presses the engagement piece 33a against the stopper 42b as shown by the dotted line, the meshing portion of the first transmission gear 21 (small transmission gear 21a) and the second transmission gear 22 prevents the idling. Therefore, it becomes impossible to rotate any further in the G direction. When the second output shaft 3b starts to reverse in the A direction when the actuating member 33 is partially protruded, the rotary plate 31 rotates in the G direction, so that the spring 3
4, the actuating member is pulled back.
If the blocking force of the blocking section is to be strong, the actuating member 33 can be pulled back by increasing the pulling force of the spring 34.

When the second output shaft 3b of the motor rotates in the B direction, the rotary plate 31 also rotates in the H direction (actuation direction), so the engagement protrusion 31a engages with the engagement piece 33a, which is indicated by the arrow. Move in the direction of motion. In this embodiment, the ejection mechanism is configured to linearly protrude in and out in the lateral direction to obstruct (e.g. eject) a racing car or the like running next to it.

To explain the operation in the above configuration, first, when the motor 3, which is configured to be rotatable in two forward and reverse directions, is continuously rotated in one direction, for example, the direction A, the first and second output shafts 3a, 3b is A at the same time
Start rotating in the direction. When the first output shaft 3a rotates in the A direction, the crown gear 13 rotates in the C direction, and the pinion gear 12a rotates to the right driven gear 7a.
When the first output shaft 3b rotates in the B direction, the crown gear 13 rotates in the D direction and the pinion gear 12b rotates in the left driven gear 7b. The tires 6a and 6b are also rotated in the forward direction. The operation of the first gear mechanism 10 allows the vehicle body to move forward (or backward). Note that in this embodiment, only one wheel (rear wheel) is driven by the motor;
The front and rear wheels may be driven simultaneously (four-wheel drive).

Next, when the second output shaft 3b rotates in the A direction,
Torque transmission is attempted to be performed sequentially through the first, second, and third transmission gears 21, 22, and 23, but the torque transmission cutoff section
1 (21a) and 22, the actuating member 33 that constitutes the ejecting mechanism does not operate. When the second output shaft 3b rotates in the B direction, the rotating plate 31 also rotates in the H direction, so the engagement protrusion 31a acts on the engagement piece 33a of the actuating member 33 to move the actuating member 33 in the operating direction. . The pulling back of the actuating member 33 at the completion of the operation or during the operation is performed by the cooperation of the spring 34 and the rotary plate 31, or by the spring 34 alone.

In addition, in the above-mentioned embodiment, the drive source for driving is shared as the drive source for the push-down mechanism, but
It is not necessarily limited to this. The push-down mechanism may be a drive source separate from the travel drive source.

(Effects of the Invention) As described above, since the traveling toy according to the present invention includes the traveling mechanism and the ejecting mechanism of the ejecting means, not only can the traveling mechanism enjoy normal running, but also the ejecting mechanism allows the traveling toy to You can enjoy a game-like driving experience by interfering with the driving of cars. Therefore, according to the present invention, the functionality and usefulness of the traveling toy can be improved.
