The riding toy A includes a toy body 5 having a substantially car body shape, and front and rear axles 4, 4 which are pivotally supported below the toy body 5 and have left and right wheels 3, 3 at both ends. ,
The toy body 5 includes a backrest frame 2 attached to the rear of the seat 1 at the rear end of the upper surface, a braking mechanism 10 attached to the rear end of the lower surface of the toy body 5, and the like (see FIG. 1).

The toy main body 5 is formed by integrally molding a resin material with a thickness enough to withstand the load when the infant 8 straddles, and is formed into various vehicle body shapes by the design of the riding toy A.

The rear axle 4 is rotatably supported by penetrating the rear side of the toy body 5. An intermediate portion of the axle 4 penetrates a tilt stopper 9 described later. And each of these front and rear axles 4, 4
Wheels 3 are fitted and fixed to both ends thereof, that is,
The axle 4 and the wheel 3 are configured to rotate integrally.

The inclined stopper 9 has a central vertical cross section having a substantially U-shape. One side of the upper side is fixed to the rear end of the lower surface of the toy main body 5 by fastening means 21 composed of bolts and nuts. The side portion has a rectangular shape in plan view extending along the rear axle 4. When the infant 8 puts weight on the backrest frame 2, the tilt stopper 9 causes the lower end 9 a to abut on the ground so that the front side of the toy body 5 supports the rear wheel 3. To prevent it from floating.

The backrest frame 2 has a substantially U-shaped frame shape in plan view with its opening facing downward, and both lower ends are fitted to the rear end of the upper surface of the toy main body 5. Is formed in a shape that the infant can easily grasp from behind so as to also serve as the pushing rod.

The braking mechanism 10 includes an engaging member 11 which approaches and separates from the outer peripheral surface of the rear axle 4,
And a knob 14 for rotating the close-up and separation of the toy, and is attached to the toy body 5 via the inclined stopper 9.

The engaging member 11 is formed in a substantially elongated hole shape into which the axle 4 is loosely inserted, and has an engaging frame 12 for moving the front end side 12a of the inner surface toward and away from the outer peripheral surface of the axle 4;
The engagement frame 12 includes a screw portion 13 integrally formed at the rear end.

The engagement frame 12 has a front end 12a on the inner surface thereof.
The axle 4 is formed in a vertical cross section in the shape of a vertical cross section so as to abut on one half of the outer peripheral surface of the axle 4 at two points.
By sliding the outer peripheral surface so that the axle 4 is sandwiched between
The sliding contact resistance is sufficiently ensured. The threaded portion 13 is formed in a male screw shape that makes the axle 4 and the axis substantially orthogonal to each other.

The knob member 14 has a female screw-shaped threaded portion 15 to be screwed into the screwing portion 13 at the front end side, and a disk-shaped knob portion 16 at the rear end side. It is coaxially formed integrally with the toy body 5, and is rotatably supported above the inclination stopper 9 in a state where the knob 16 is directed obliquely upward and rearward of the toy body 5.

Reference numeral 7 in the drawing denotes a handle 7 rotatably supported on the front side of the upper surface of the toy body 5, and a switch such as a horn or an electronic music box provided in the toy body 5 as necessary. Is provided on the upper surface of the handle 7.

According to the riding toy A, when the knob 16 of the knob 14 is turned clockwise from behind,
Engaging member 1 screwed with threaded portion 15 of knob member 14
1 is drawn to the knob member 14 side, and the inner surface front end side 12a of the engagement frame 12 approaches the axle. When the knob 14 is continuously rotated, the inner surface front end 12
a slides on one half surface of the outer peripheral surface of the axle 4 and gives a rotational resistance to the axle 4. At this time, since the axle 4 is slid on the outer peripheral surface so as to be sandwiched at two points by the inner surface front end side 12a of the vertical cross-section C-shape, a sufficient sliding contact resistance according to the tightening and tightening of the knob member 14 acts. I do. Therefore, by adjusting the tightening and tightening of the knob member 14 according to the walking ability and the growth degree of the infant 8, the sliding contact resistance can be varied, so that the axle 4 and the wheel 3 integrated with the axle 4 are formed.
Can adjust the rotational resistance.

In the riding toy A, the braking mechanism 10
Is attached to the toy body 5 via the inclined stopper 9, but as in the riding toy B exemplified as a reference example in FIG. 4, the inclined stopper 9 is omitted, and the knob 16 is raised on the bottom surface inside the toy body 5 '. To the main body 5 'of the toy body 5' so that the
Inner surface tip end 12a is configured to abut the axle 4 and sliding the
It is also possible . In this case, the effect of imparting rotational resistance to the axle 4 and the wheel 3 is provided in the same manner as the riding toy A, and the seat 1 'is provided so as to cover the upper surface of the toy body 5', so that the infant can mischief the knob. Turning 16 can be avoided. Note that other configurations of the riding toy B are the same as those of the riding toy A described above, and thus redundant description will be omitted.

Further, according to the riding toys A and B, the engaging member 11 is configured so that the front end side 12a of the inner surface of the engaging frame 12 is in sliding contact with the axle 4, but the rear end of the inner surface of the engaging frame 12 is formed. The side may be configured to be in sliding contact with the axle 4. In this case, it is preferable that the rear end side of the inner surface of the engagement frame 12 be formed in a C-shape in vertical cross section, as in the above embodiment. According to this configuration, in order to impart rotational resistance to the axle 4 and the wheels 3, the engaging member 11 is advanced by rotating the knob member 14 counterclockwise, contrary to the above-described embodiment, and The rear end side of the inner surface of the joint frame 12 may be brought into sliding contact with the axle 4.

Since the present invention is configured as described above, it has the following effects. Because the rotational resistance of the wheels can be adjusted by the braking mechanism, the toy body advances too far forward by increasing the rotational resistance, even when the child is just standing up and is used for walking training of an infant with a poor sense of balance. Can be prevented, and the infant who has weighed forward can be prevented from falling forward. Furthermore, in the case of an infant who has been equipped with walking ability to some extent, by reducing the rotation resistance,
You can practice walking with increased walking speed. In addition, when an infant accustomed to walking plays by straddling or pushing, it can be used as a conventional riding toy by further reducing the rotation resistance. In addition, the front end side of the inner surface of the engagement frame
Or, abut the rear end of the inner surface at one point on one half of the outer peripheral surface of the axle.
By forming it in a vertical cross-section in the shape of a letter C,
Contact resistance can be secured. In addition, the infant can put weight on the backrest frame.
When it is hung, the lower end of the tilt stopper
The front side of the toy body floats with the rear wheel
Can be prevented. Therefore, it is possible to provide a riding toy that can safely perform a walking exercise according to the walking ability of the infant and that can be safely played by infants of various ages.
