Description

[Detailed description of the invention] Technical field to which the invention pertains This invention relates to a traveling toy whose traveling direction is changed to a set direction at a set time.

Conventional technology and its disadvantages Conventional running toys that change the direction of travel while running use a card system to set the direction of travel, and in order to obtain various conversion modes, a large number of cards are required. It is troublesome to handle and store;
In addition, the convertible direction of travel is limited, and the player cannot set the direction at will.

Purpose of this invention In view of the above points, this invention has made it possible to arbitrarily set the conversion direction and conversion timing by inserting an operating pin into a through hole at an arbitrary position among a large number of through holes. The purpose is to provide running toys.

Embodiment of this invention Next, an embodiment of this invention will be described based on the drawings.

Figure 1 shows the first model realized in the disc-shaped traveling toy _T1 .
An example is shown in Fig. 2, which shows a running toy in a normal form.
An example realized in _T2 is shown.

Below, what is shown in FIG. 1 will be explained in detail.

As shown in Fig. 3, the traveling toy _T1 includes a circular plate-shaped substrate A, a circular lid B fixed to the top surface of this substrate with screws, etc., and is rotatably supported at the center of the lid. It has a disc-shaped rotating plate C.

As shown in FIG. 4, the board A is provided with one front wheel 1 and a pair of rear wheels 2, which are free wheels projecting from the bottom surface of the board A. As clearly shown in FIGS. 3 and 5, the steering shaft 3 of the front wheel 1 projects from the upper surface of the base plate A, and a bifurcated first switch member sw ₁ is connected to the upper end of the steering shaft 3. One end of the first switch is connected to the other ends of elastic members 6 and 7, such as coil springs and rubber strings, which have one end locked to the locking pieces 4 and 5, respectively, so that in the natural state, the first switch _SW1 is The protrusions p ₁ and p ₂ provided at both ends are maintained on a straight line extending radially from the center of the substrate,
Front wheel 1 is facing forward.

On the top surface of the board A, there are battery storage sections 8 on both the left and right sides.
9 is provided in a protruding manner, and a lid 10 provided on the bottom surface of the board in each battery housing section can be opened and closed to allow loading and replacing of batteries.

Between the battery storage parts 8 and 9, a motor 11 using the battery as a power source, a gear train 12 to which rotational force of the motor is applied, and the gear train and the rear wheel 2 are provided.
The rotational direction switching unit 1 provided between the axle 13 of
4, and a transmission section 15 that receives rotational force from the gear train and transmits it to the rotary plate C.

The gear train 12 includes gears fixed to a motor shaft,
This gear is for speed reduction and is constructed by sequentially meshing a plurality of gears supported between a pair of bearing plates 16 and 17.

A pinion 12f having a large axial length and a pinion 12g having a small axial length are fixed on the shaft of the descending gear 12e of the gear train 12.

The rotation direction switching section 14 has two bearing plates 16, 1
Gears 14b and 14c are fixed to both ends of a slide shaft 14a that is slidably supported in the axial direction by 8.
The gear 1 is mounted on the gear 14c side on the shaft 14d, which is supported by the bearing plates 16 and 18 so as not to move in the axial direction.
4e, and gears 14f and 14g are fixed on the axle 13 of the rear wheel at positions corresponding to the gears 14b and 14c, respectively, and the gear 14b
is carried by a swinging arm 14h, and a second switch _SW2 is connected to the end of the swinging arm.

The swing arm 14h has bearing plates 16 and 18.
A cover 19 fixed to cover between the upper ends of the
The pin 23 of the second switch SW 2 is attached to the lower surface of the cover 19 so as to be swingable about the shaft 20, and the second switch SW ₂ is attached to the upper surface of the cover 19 so as to be rotatable about the shaft 22.
is inserted into the long hole 24 of the swing arm, so when the second switch is rotated within the range regulated by the lid B, the swing arm 14h rotates and the shaft 14a is rotated through the gear 14b. It is designed to move within a predetermined range in the axial direction.

In addition, the protrusion provided on the top surface of the second switch SW ₂
When p ₃ and p ₄ are located on a straight line extending in the radial direction from the center of the board A, the rotation direction switching section is in a neutral state, and the gears 14b and 14c are separated from the gears 14f and 14e, respectively. ing. However, the gear 14b is always engaged with the pinion 12f no matter which direction the shaft 14a moves, and the gear 14b is connected to the shaft 14 through the second switch.
They engage only when a is moved in one direction. Also, the gear 14c is separated from the gear 14e when the gear 14b meshes with the gear 14f;
It is positioned so that it meshes with 14e when it is separated from . Gears 14e and 14g are always meshed.

With the configuration of the rotation direction switching section described above, when the second switch sw ₂ is neutralized without applying any force to either of the protrusions p ₃ or p ₄ , the gears 14b and 14c are separated from the gears 14f and 14e, respectively. Motor 11
Even if a rotational force of 2 is applied through the gear train 12, the rear wheel 2 is stationary and the traveling toy does not travel.

On the other hand, when the second switch SW ₂ is rotated in one direction, the gear 14b is rotated through the swing arm 14h.
is engaged with 14f and the rear wheel 2 rotates forward, so this traveling toy travels forward.

Furthermore, when the second switch is rotated in the other direction, the shaft 14a is moved in the opposite direction by the swing arm 14h, so the gear 14b is separated from the gear 14f, and the gear 1
Since 4c engages with 14e, the shaft 14a is reversed and the running toy therefore runs backwards.

When the lid B is fixed to the substrate A, a pair of arcuate holes h ₁ , h ₂ , h ₃ , h ₄ provided on opposite sides of the support shaft 25 protruding from the center of the lid are provided. The protrusions _{p 1 ,} p ₂ , p ₃ , p ₄ of the switches sw 1 , sw ₂ are respectively inserted, and each switch is rotatable within the length range of the circular arc of each hole. For the first switch, the front wheel can change direction to the left or right without contacting the board, and for the second switch, when the front wheel rotates in one direction or the other direction, the gears 14b and 14c change to the gear 14f as described above. , 14e, so as to be engaged with or separated from each other in a predetermined relationship.

The transmission part 15 is a gear 1 at the end of the gear train 12.
Crown gear 15a and pinion 1 that mesh with 2g
5b, a gear 15c, a cylinder 15d, and a pinion 15e provided at the upper end of the cylinder and protruding upward from a hole 26 in the lid B. The crown gear 15a and pinion 15b are attached to the base plate A by a shaft 15f, and the gear 15c and tube 15d are held to the base plate by a shaft 15g. By making the diameter of the cylinder 15d larger than the diameter of the hole 26 of the lid B, the cylinder is rotatably held between the substrate A and the lid when the lid is attached.

With such a configuration, when the motor 11 rotates, the pinion 15e is rotated in a fixed direction.

The rotary plate C has a fitting hole 27 in the center, and the supporting shaft 25 of the lid B is fitted into the fitting hole, and a screw is screwed into the supporting shaft 25 from above the fitting hole 27. It is rotatably mounted. Also, on the rotating plate C,
A large number of through holes H that vertically penetrate the rotating plate on at least four concentric circles centered on the fitting hole.
1 ₁ ~ H1 _o , H2 ₁ ~ H2 _o , H3 ₁ ~ H3 _o , H4 ₁
~H4 _o are arranged in an arbitrary arrangement state. In the illustrated example, four rows of through holes are arranged in a radial manner, but the invention is not limited to this.

There is a predetermined relationship as shown in FIG. 7 between each of the through holes and each pair of holes h ₁ to _{h 4} through which the switches and protrusions p ₁ to _{p 4} of the lid are inserted. There is.
In other words, a pair of holes h ₁ and h ₂ for the first switch sw ₁
are provided at positions corresponding to the through holes H1 and H3 in the first and third rows from the outer periphery of the rotating plate, and
A pair of holes h ₃ and h ₄ for the second switch are similarly provided at positions corresponding to the through holes H2 and H4 in the second and fourth rows. Therefore, when the rotary plate C is rotated by the transmission section 15, each row of through holes moves and passes above one of the holes _h1 to _h4 of the lid B, respectively.

In FIGS. 1 and 3, P ₁ to _{P o} are all actuating pins formed in the same size, and can be inserted into through holes at arbitrary positions of the rotary plate, and can be inserted into through holes in a predetermined row. When inserted into the hole, the lower end of the operating pin contacts the protrusions p ₁ to _{p 4} of the switch that protrude upward from the predetermined holes of the lid B, and the protrusions are inserted into the holes h ₁ to _{h 4} in the longitudinal direction. In order to move the switch, in the case of the first switch, it is rotated in one direction around the steering shaft 3, and in the case of the second switch, it is rotated in one direction around the shaft 22. let

However, if the actuating pin is not inserted into any of the through holes, the protrusions of any of the switches will not receive any force and will be in a neutral state.

With the above configuration, the power switch 28 provided on the bottom surface of the board A can be operated without inserting any operating pins.
When turned ON, the motor 11 rotates and the gear train 12
The shaft 14a of the rotational direction switching section 14 is rotated through the transmission section 15, and the rotary plate C is rotated in a fixed direction through the transmission section 15. In this case, the first switch SW ₁ is in the neutral position and the front wheel 1 is facing straight ahead, but it is not specified whether the second switch SW ₂ is in the neutral position, the forward position, or the reverse position. . Therefore, when the traveling toy is placed on a flat surface and the user's hand is released, the rotary plate C rotates and moves straight forward or backward depending on the state of the second switch.

On the other hand, after inserting the operating pin P into one of the through holes of the rotary plate, turn on the power switch.
Then, when this traveling toy is placed on a flat surface, if the operating pin is inserted into the through hole at a predetermined position, it will come into contact with the protrusions p ₁ to _{p 4} of one of the switches due to the rotation of the rotary plate. Rotate that switch.

Referring again to FIG. 7, when the actuating pin P is inserted into the through hole of the first row H1, the actuating pin is pushed into the protrusion of the first switch _SW1 by rotation of the rotating plate C, for example, in a _clockwise direction. Rotate the switch clockwise via p ₁ . Therefore, the moving direction of the traveling toy, which had been traveling straight until then, is changed to the right.
On the other hand, when the operating pin is inserted into the through hole of the third row _H3 , the first switch _SW1 is rotated counterclockwise by the operating pin and the protrusion _P2 , so that the running toy The direction of travel is changed to the left.

In addition, when the operating pin is inserted into the through hole of the second row _H2 , when the operating pin reaches the corresponding position of the second switch by rotating the rotating plate clockwise in FIG. In order to rotate the second switch _SW2 clockwise in FIG. 7 via the protrusion _p3 , the shaft 14a is rotated to the left in FIGS. direction, and move gear 14b to 14f.
mesh with. Therefore, since the rear wheels 2 are rotated in the normal direction, the traveling toy moves forward.

On the other hand, when the actuation pin is inserted into the through hole of the fourth row _H4 , the actuation pin moves counterclockwise in Fig. 7 through the projection _p4 of the second switch due to the rotation of the rotary plate. Due to the rotation, the swinging arm 14h is moved to the right in FIGS. 5 and 6, so that the gear 14b moves away from the gear 14f and the gear 14c meshes with the gear 14e. Therefore, the rear wheel 2 is reversely rotated by the gear 14g, so that the traveling toy moves backward.

Then, after the running toy is grounded on the running surface,
When to steer and when to change direction is determined by the circumferential distance from the first switch and second switch of the through hole into which the operating pin P is inserted, and
The direction in which it travels is determined by which row of through holes the actuating pin is inserted into. Therefore, by variously changing the insertion position of the operating pin, the traveling direction of the traveling toy can be set in various ways.

If a large number of through holes are provided in the rotary plate, as in the example shown, by inserting the operating pin into the appropriate through hole, the traveling toy can be combined with straight parts, curved parts, etc. It is also possible to have fun by driving the vehicle along a prescribed travel path and competing to determine the accuracy of the position where the operating pin is inserted.

The one shown in FIG. 2 includes a motor, a gear train, a rotational direction switching section, and a transmission section provided on the board A shown in FIG. 3 within the body of a conventional traveling toy.
An empty board A ₁ , a lid B ₁ (not visible in Figure 2), and a rotating plate C ₁ are attached to the upper part of the body, and the first switch SW ₁ linked to the front wheel 1a is linked to the rotation direction switching section. A second switch _SW2 is provided on the lid B.

Effects of this invention As described above, according to this invention, there is provided a traveling body having a motor, a gear train, a wheel, a rotational direction converting part, and a transmission part, and a rotating force of the motor is applied to the traveling body from the transmission part. and an actuating pin that is detachably inserted into a number of through holes of the rotary plate and engages and operates the rotational direction converting portion by rotation of the rotary plate. Because of this, the conversion direction and conversion timing can be set at will by simply inserting the actuation pin into any of the many through holes, and it can be run in any manner with simple operations. You can enjoy it.
