Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a running toy that is capable of stabilizing straight travel and enhancing driving force when changing direction and starting running.

(Prior art and its problems) Conventionally, in this type of traveling toy (remotely controlled), a support member for supporting running wheels (front wheels) is rotatably supported on a chassis, and one of the running wheels is One of them is connected to a drive mechanism, and the other one is configured to rotate independently. and,
The support member is configured to rotate only in a direction opposite to the direction of rotation driven by the running wheels associated with the drive mechanism. however,
Although the above-mentioned running toys can easily change direction, since the driving force is applied only to the running wheels linked to the drive mechanism at the time of starting, it is not possible to achieve stable running in the straight direction, and there are problems such as a lack of power. This is a difficult point, and it was hoped that this would be resolved.

(Problems to be solved by the invention) The present invention has been made in view of the above-mentioned points of view, and it provides a running toy with excellent power, as well as stable running in the straight direction, especially when changing direction and starting. The purpose is to make suggestions.

(Means for Solving the Problems) As a means for solving the above problems, a traveling toy according to the present invention is characterized by having the following requirements.

(a) The support member that supports the running wheels must be rotatably supported in the horizontal direction on the chassis.

(b) One of the above running wheels is fixed to a drive shaft linked to a drive mechanism, and the other one is loosely attached to the drive shaft.

(c) A gear is fixed to the end of the drive shaft on the side of the running wheel that is loosely attached, and a planetary gear arranged on the outside of the wheel base of the running wheel is always meshed with the gear. .

(d) The planetary gear is housed so as to be movable within a space formed on the outside of the wheelbase, and the running toy runs in one direction on one side of the wheelbase with the planetary gear in between. A locking piece whose tip is locked to the planetary gear that moves when the device is moved is formed on the other side, and a contact piece that abuts the planetary gear is formed facing the space.

(e) The supporting member rotates with respect to the vehicle chassis so that the fixed traveling wheel among the traveling wheels does not go around further forward than the loosely attached traveling wheel, and is oriented so that it can travel straight ahead at the maximum. be regulated.

(Operations and effects of the invention) According to the above configuration, since the pinion rotates together with the drive shaft by operating the drive mechanism,
The planetary gear rotates and locks into the locking piece on the wheel base. The planetary gear cannot rotate any further. Therefore, the pinion, the planetary gear, and the locking piece of the wheel base are in a fixed state, and the wheel base rotates along with the rotation during driving. Further, the support member is regulated to rotate with respect to the vehicle chassis so that the fixed traveling wheel among the traveling wheels does not go around further forward than the loosely attached traveling wheel, and is oriented in a direction in which it travels straight ahead at the maximum. ing. Therefore, the traveling toy travels straight.

Next, when the transmission signal from the remote control unit is stopped while driving, the pinion fixed to the drive shaft that is linked to the drive mechanism is braked, whereas the running wheels rotate by inertia, so from now on, they will not come into contact. The piece comes into contact with the planetary gear and presses against it. As a result, the planetary gear is pushed out, so that the locking state with the locking piece is released, and the planetary gear idles while contacting the contact piece.
Therefore, the loosely attached running wheels continue to rotate due to inertia. On the other hand, the other running wheel is fixed to the drive shaft and is braked. Therefore, the running toy changes direction towards the fixed running wheels.

(Example) Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.

In the figure, symbol A indicates a traveling toy according to the present invention. This traveling toy A has a remote control unit 2 mounted in the center of a chassis 1, and the remote control unit 2 receives a transmission signal from a remote control unit (not shown) and operates a drive mechanism. It is formed like this. Since the remote control structure of the traveling toy A is well known, its explanation will be omitted.

As shown in FIG. 2a, the traveling toy A has a support member 4 rotatably installed in the horizontal direction on the upper front surface of the chassis 1 via a support shaft 3. The drive shaft 6 is connected via the provided bearings 5, 5.
is rotatably supported. A pinion 7 is fixed to one side of the treetop from the center of the drive shaft 6, and running wheels 8, which are front wheels, are mounted at both ends.
8 is provided.

One of the running wheels 8, 8 is fixed integrally with the drive shaft 6, and the other is rotatably attached to the drive shaft 6. A pinion 9 is fixed to the end of the drive shaft 6 on the side of the running wheel 8 which is loosely attached thereto. are always engaged.

The planetary gear 11 is mounted on the wheel base 10 as shown in FIGS. 1a and 1b.
A locking piece 13 whose tip locks on the planetary gear 11 that moves when the traveling toy A travels in one direction is on one side with the two sides in between, and a contacting piece 13 that abuts on the planetary gear 11 on the other side. Each piece 11 is formed facing the space. Note that 14 is a wheel cap. When the traveling toy A travels forward, the planetary gear 11 moves within the space 15 and is configured to lock onto the short locking piece 13. Reference numeral 16 indicates a locking member protruding from one rear side of the support member 4, and the locking member 1
6 is formed so as to come into contact with one side of the vehicle chassis 1 near the front. With this, the support member 4
With respect to the chassis 1, the rotation of the fixed running wheel 8 of the above-mentioned running wheels is restricted in front of the loosely attached running wheel 8 so that it does not turn around and travels straight at the maximum. ing.

A drive mechanism consisting of a motor 18 electrically connected to the remote control control section 2 is mounted on the support member 4, and a crank gear 19 fixed to the output shaft 18a of the motor 18 is connected to the drive shaft 6. It is meshed with a fixed pinion 7. This causes one of the running wheels 8, 8 to be linked with the motor 18. Reference numerals 21 and 2 indicate bearing portions provided on both rear sides of the chassis 1, and the bearing portions 21 and 21 include an axle 22.
is supported, and running wheels 23, 23 forming rear wheels are rotatably attached to both sides thereof.

Since the traveling toy A is configured as described above, in order to use it, first, the remote control unit 2 mounted on the vehicle chassis 1 receives a transmission signal from the remote control unit (not shown). Accordingly, a support shaft member 4 rotatably provided on the chassis 1 via a support shaft 3 is provided.
A drive mechanism consisting of a motor 18 mounted on the drive mechanism is activated, and running wheels 8, 8, which are front wheels attached to a drive shaft 6 driven by the motor 18, are activated.
It is possible to run by rotating one of the two. At this time, as shown in FIGS. 1a and 1b, the outer side of the wheel base 10 of the running wheel 8 that is fixed to the end of the drive shaft 6 and is always in mesh with the pinion 9 is attached to the drive shaft 6. Since the planetary gear 11 disposed in the space 15 moves within the space 15 and is locked to the locking piece 13, the planetary gear 11 cannot rotate. Therefore, the pinion 9, the planetary gear 11, and the locking piece 13 of the wheel base 10 are in a fixed state, and the wheel base 10 rotates with the rotation of the drive shaft 6. In addition, in the above, as shown in FIG.
is held in contact with one side of the front part of the chassis 1, so that the traveling toy A can be made to travel straight ahead.

Next, when the transmission signal from the remote control unit is stopped while driving, the pinion 9 fixed to the drive shaft 6 linked to the drive mechanism is braked, while the running wheels 8 rotate by inertia. The contact piece 12 contacts the planetary gear 11 and presses it. As a result, the planetary gear 11 is pushed out, so the locking piece 13
The locked state with the planetary gear 11 is released, and the planetary gear 11 idles while contacting the contact piece 12. Therefore, the traveling wheels 8 continue to rotate due to inertia. On the other hand, the other running wheel 8 is fixed to the drive shaft 6. Therefore, the traveling toy A changes direction toward the fixed traveling wheels 8 as shown in FIG. 2b.

Note that as a remote control method for the traveling toy A, in addition to radio control, a remote control may be adopted.
