Description

[Detailed explanation of the idea] The present invention relates to a steering mechanism for a traveling toy.

As shown in FIG. 1, a drive wheel 1 and an idler wheel 1', an axle 2 to which these wheels 1 and 1' are attached at both ends, a bearing 3 to which the axle 2 is attached, and a bearing 3 to which the bearing 3 is attached. The car body 4 that is extending and the axle 2 that is attached to the car body 4
It is equipped with a variable speed drive device (not shown) that rotates the wheels 1 and 1' at high speed or low speed, and the drive device rotates the axle 2 and wheels 1 and 1' at a high speed and at a low speed for high speed or low speed travel. Traveling toys that can be moved are well known.

By the way, most of the conventional traveling toys of this type can only move in a straight line, but cannot move in a non-straight line, that is, in a curved direction.

This is because, in general, a complicated M steering mechanism must be installed in order to make the toy move through a curve, making the traveling toy very expensive.

In the traveling toy having the above-mentioned structure, as shown in FIG. The bearing 3, which has been rotated by the driving force of the drive wheel 10, is stopped in a straight forward state.One end of the collar 6 is locked to the vehicle body 4, and the other end is locked to the bearing 3. The above-mentioned drawbacks of the conventional method are solved by configuring a steering mechanism with a spring 5 that rotates the bearing 3 to a non-straight traveling state when the driving wheel 1 is stopped and the rotational driving force of the driving wheel 1 is less than a set value. It is.

The bearing 3 is formed in the shape of a case, and a driving device including a motor, gears, etc. (not shown) is housed inside the bearing 3.

The spring 5 is attached to the vehicle body 4 at its center by a spring receiving piece 9, and in a doglegged state, one end 5a of the spring 5 is fixed to the bearing 3 and the other end 5b is fixed to the vehicle body 4. This applies a counterclockwise rotational force to the bearing 3.

10 is a spring receiving piece for locking one end 5a of the spring 5 to the bearing 3, and 11 is a spring guard for locking the other end 5b of the spring 5 to the vehicle body 4.

In addition, the stopper 6 has a nut 6a fixed to the vehicle body 4,
The bolt 6b is screwed onto the nut 6a, and the tip of the bolt 6b presses one side of the bearing 3 to restrict rotation of the bearing 3.

The reference numeral 7 designates a thrust bearing for attaching the idle wheel 1' to the axle 2 for idle rotation, and the reference numeral 12 designates a second stopper provided on the vehicle body 4 to restrict rotation of the bearing 3 in the counterclockwise direction.

Since the present invention is a steering mechanism configured as described above, when the toy is run by rotating the wheel 1 with a rotational driving force exceeding a set value, the clockwise direction is applied to the bearing 3 by the rotational driving force of the wheel 1. The rotational force overcomes the counterclockwise rotational force applied to the bearing 3 by the spring 5, and the bearing 3 is rotated clockwise until it hits the stopper 6, causing the toy to move straight.
Also, when the wheel 1 is rotated with a rotational driving force below the set value and the toy is run, the counterclockwise rotational force applied to the bearing 3 by the spring 5 is due to the rotational driving force of the wheel 1. Overcoming the clockwise rotational force applied to the bearing 3, the bearing 3 is rotated until it hits the second stopper 12,
This makes the toy move in a non-straight direction, or in a curved direction.

In addition, even if the speed change by the variable speed drive device is made in two stages, high and low speed, and the toy moves straight when traveling at high speed, and the toy moves at a predetermined bending angle when traveling at low speed, or the variable speed drive device The toy may be configured to be able to perform stepless gear changes, such that the toy travels straight when running at maximum speed, and gradually increases the turning angle as the speed decreases.

Further, the speed change is performed by an appropriate means such as wirelessly changing the gears of the speed change drive device.

As explained above, the present invention includes a driving wheel, a driven wheel, an axle to which these wheels are attached to each end,
It includes a bearing to which the axle is attached, a vehicle body to which the bearing is attached, and a variable speed drive device attached to the vehicle body for rotating the axle or wheel at high or low speed, and the drive device rotates the axle or wheel at high speed. A traveling toy that can be rotated at a low speed for high-speed or low-speed travel includes a pivot shaft that supports the bearing on the vehicle body so as to be rotatable in the left-right direction, and a pivot shaft that is attached to the vehicle body. a stopper for stopping the bearing rotated by the rotational driving force of the driving wheel in a straight-line state; This steering mechanism for a traveling toy is characterized by consisting of a spring that rotates the bearing in a non-straight state when the speed is below a set value, so it has a simple structure and is a simple method for changing the traveling speed of the toy. This has the effect that the toy can be reliably moved straight or in a curved direction.
