Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a changeable direction in a traveling toy that automatically changes direction while running.

(Prior Art and Object of the Invention) Conventionally, a traveling toy equipped with a drive unit can only travel straight ahead and cannot automatically change direction while traveling.

Incidentally, recently, there has been a demand for such traveling toys that can automatically change direction while traveling.

(Means for Achieving the Object) As a means for achieving the above object, a direction changing device for a traveling toy according to the present invention is a traveling toy equipped with a drive unit, and is characterized by having the following requirements: shall be.

(a) One end of the gear shaft of one gear of the drive unit is made to protrude outside, and another gear is fixed to that end.

(b) A movable member is supported on the gear shaft, and a gear that is always meshed with the other gear is pivotally supported on the movable member.

(c) The chassis is provided with a gear that can freely engage and detach from the gear provided on the movable member when the movable member is in operation.

(A cam member is provided on the gear shaft of the gear provided on the vehicle chassis above the gradient, and an operating rod that is linked to a wheel that is provided to be able to change direction is engaged with the cam member.

(Operations and Effects of the Invention) As configured above, according to the direction changing device for a traveling toy according to the present invention, a gear fixed to one gear shaft of the drive unit and a gear set to the movable member are connected to each other. Since they are always meshed, the movable member can be moved by changing the rotational direction of the other gear, and the gear provided on the movable member and the gear provided on the toy body can be meshed with each other.

A cam member is attached to a gear shaft of a gear provided on the chassis, and an operating rod is engaged with the cam member, which is linked to a wheel provided so as to be able to change direction. Therefore, when the gear provided on the movable member and the gear provided on the chassis are in mesh, the cam member rotates and the direction of the wheel can be changed via the operating rod.

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

1 and 2, reference numeral 1 indicates a running toy to which the direction changing device for a running toy according to the present invention is applied, and the running toy 1 is equipped with a drive unit a.

One end of the gear shaft 2 of one gear of the drive unit a projects outward from one side of the drive unit a, and another gear 3 is fixed thereto.

Further, a movable member 4 having a substantially rectangular shape is rotatably supported on the gear shaft 2 located outside the gear 3, and the tip of the movable member 4 is always meshed with the gear 3. The gear 5 that is attached is pivoted. The rotation range of the movable member 40 is regulated by a stopper member 6 provided diagonally above the side surface of the drive unit a. In this case, the movable member 4
Even when the gear 3 rotates, the state of engagement between the gear 3 and the gear 5 provided on the movable member 4 is maintained.

A gear 7 is disposed above the movable member 4, and a gear shaft 8 of the gear 7 is supported by a support member 9 provided on the chassis 1a. A cam member 10 is removably provided at the upper end of the gear shaft 8 and protrudes from the upper part of the vehicle body 1b. The gear 7 and the gear 5 provided on the movable member 4 are formed to mesh with each other when the movable member 4 rotates upward. by this,
The driving force of the drive unit a can be transmitted to the cam member 10.

A mounting member 13 to which a front wheel (wheel) 12, 12 is attached is pivotally supported on a support shaft 11 provided at the center of the front part of the chassis 1a so as to be movable back and forth, and the mounting member 13 is provided closer to one example. It is always biased in one direction by the elastic member 14. Further, an operating rod 15 is attached to the other side band of the mounting member 13.
is attached by a support shaft 16, and the operating rod 15
A rising portion 15a provided at the end of the chassis 1a protrudes from the top of the chassis 1a and is always in contact with the rear part of the cam member 4.9 This allows the operating rod 5 to move forward and backward as the cam member 4 rotates. The front wheel (wheel) 12.12 attached to the mounting member 13 can be changed in direction by moving.

The drive mechanism (not shown) of the drive unit a is conventionally known, and uses a mainspring as a drive source and transmits its driving force via a plurality of reduction gears to a drive shaft 17 to which rear wheels 16, 16 are attached.
It is intended to be transmitted to Note that the drive source is not necessarily limited to a spring, and may be a motor, friction, etc., for example.

Since the traveling toy 1 is constructed as described above, when using it, when the traveling toy 1 is pulled back to wind up the drive unit A mainspring and then released, the unwinding force of this mainspring is transmitted through the drive mechanism. The signal is transmitted to the drive shaft 17 of the rear wheels 16, 16, thereby allowing the traveling toy 1 to travel. In the above, when winding up the mainspring of the drive unit a, the gear 5 provided on the movable member 4
Since the movable member 4 is in the downward movement state and the gear 7 provided on the chassis 1a via the support member 9 is disengaged, it is recommended that the front wheels (wheels) 12 and 12 remain in the same state. held. Next, while the traveling toy 1 is running, the movable member 4 is moved upward by the unwinding force of the mainspring, and the gear 5 and the gear 7 are engaged with each other. As a result, as the cam member 10 rotates, the operating rod 15 engaged with the cam member 10 is pulled rearward, causing the operating rod 1 to rotate.
The direction of the front wheels 12.12 can be changed by rotating the mounting member 13 to which the front wheels (wheels) 12.12 linked to the front wheels 12.12 are attached about the support shaft 11.

According to the traveling toy 1 to which the direction changing device for a traveling toy is applied as described above, in the process of traveling by the driving force of the driving unit a, the operating rod 15 is actuated by the cam member lO linked to the driving unit a. Front wheel (wheel) 1
Since the direction of 2.12 can be changed, it is possible to enjoy interesting running play with the running toy l.
