BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a locking device used in combination with a child vehicle, which enables the child vehicle to use a locking operation different from a normal usage. is there.

[0002]

2. Description of the Related Art Japanese Patent Application Laid-Open No. 3-47287 by the present applicant.
The publication discloses a locking device that is interesting for this invention. The locking device shown here
A curved surface that bulges downward is formed on the lower surface, and has a height to lift the child vehicle so that the wheel of the child vehicle is separated from the ground or the floor when mounted on the child vehicle. ing.

[0003] Therefore, when such a rocking device is attached to a child's vehicle, the child's vehicle can be played as if it were a rocking chair.

[0004]

However, in a state where the above-mentioned locking device is mounted on a child's vehicle, the posture of the child's vehicle is naturally unstable, so that only one infant rides on the child's vehicle. When trying to do so, accidents often occurred in which children's vehicles fell.

[0005] It is therefore an object of the present invention to provide a locking device used in combination with a children's vehicle, wherein the risk of falling as described above is extremely low.

[0006]

SUMMARY OF THE INVENTION This invention, like the conventional locking device described above, is combined with a children's vehicle comprising a vehicle body holding a seat and rotatable wheels provided below the vehicle body. It is directed to a locking device to be used, in order to solve the above-mentioned technical problems, a base member which is settled on a fixed surface such as the ground or a floor surface, and is attached to a lower portion of a children's vehicle, In this mounting state, the wheel is in a state of being suspended in the air, and the locking member is provided so as to be lockable by an axis which is directed above the base member in a horizontal direction with respect to the base member. .

[0007]

When the child's vehicle is mounted on the locking member provided in the locking device according to the present invention, the wheels float in the air, and the child's vehicle can be locked with the locking member while being held by the locking member. State. At this time, since the locking member is held by the base member which rests on the fixed surface, the locking operation of the locking member is limited to a certain range.

[0008]

Therefore, according to the present invention, when used in combination with a children's vehicle, it is possible to obtain a locking device with a very low possibility of falling even if an infant tries to ride alone on a children's vehicle. Can be.

Therefore, by attaching the locking device according to the present invention to a child's vehicle, the child's vehicle can be
You can play safely like a rocking chair.

DESCRIPTION OF THE PREFERRED EMBODIMENTS There are various types of children's vehicles used in combination with the locking device according to the present invention.
Typical examples thereof include riding toys, tricycles for children, walkers for infants, and the like. Hereinafter, as one embodiment of the present invention, a locking device used in combination with a riding toy will be described.

FIG. 1 is a side view showing a state in which a locking device 1 according to an embodiment of the present invention is combined with a riding toy 2, and FIG. 2 is a sectional view taken along line II-II of FIG. FIG. 3 is a perspective view showing the locking device 1 alone.

The riding toy 2 includes a vehicle body 4 holding a seat 3 for a child to sit on, and a plurality of rotatable wheels provided below the vehicle body 4, for example, two front wheels 5 and two rear wheels. The wheel 6 is provided.

The front wheel 5 is connected to a lower end of a handle post 7 rotatably supported with respect to the vehicle body 4, and the direction of the front wheel 5 is changed by rotating a steering handle 8 attached to the upper end of the handle post 7. It may be configured to be changed.

The seat 3 can be opened and closed, and a storage box 9 is provided below the seat 3. The locking device 1
A base member 10 that is settled on a fixed surface such as the ground or a floor surface, and a locking member 12 that is rotatably held above a base member 10 by a shaft 11 that is oriented horizontally with respect to the base member 10. Prepare.

The base member 10 has a bracket 13 through which the shaft 11 described above passes. Also, the base member 1
On the upper surface of 0, recesses 14 and 15 are provided to provide the respective displacement ranges of the front wheel 5 and the rear wheel 6.

On the other hand, the locking member 12 has a contact surface 16 with the riding toy 2 formed on the upper surface at the center in the width direction, and the contact surface 16 is provided with a screw hole 17. Also,
Steps 18 and 19 are formed on both sides of the contact surface 16 for placing a child's foot. The lower surfaces of the steps 18 and 19 are extended in a V-shape around the position of the shaft 11 so as to form an interval between the base member 10 and the locking member 12 to allow the locking operation. To be. At the rear end of each of the steps 18 and 19, rising portions 20 and 21 are formed.

In order to reduce the shock at each end of the locking operation of the locking member 12 with respect to the base member 10,
At each end of the locking operation of the locking member 12, a spring means for exerting a repulsive force in the opposite direction is preferably added. In the embodiment shown, four compression springs 2
2 is provided as this spring means. That is,
The compression spring 22 is disposed between the front and rear ends of each of the steps 18 and 19 and the base member 10.
In order to stably position these compression springs 22, spring receiving recesses 23 and 24 are provided on the upper surface of the base member 10 and the lower surfaces of the steps 18 and 19, respectively.

Such a locking device 1 and a riding toy 2
In combination, the locking member 12 is attached to the lower part of the riding toy 2. More specifically, it is positioned so that the bottom wall of the storage box 9 of the vehicle body 4 is in contact with the contact surface 16 formed on the locking member 12, and the storage box 9 is opened in a state where the seat 3 is opened. Is screwed into the screw hole 17. Thereby, the riding toy 2 and the locking member 12 are firmly integrated.

As described above, when the riding toy 2 is combined with the locking device 1, it is preferable to mount the protective frame 26 as shown in FIGS. Protective frame 2
Numeral 6 has a shape surrounding the waist of a child sitting on the seat 3 of the riding toy 2, and prevents a child placed on the riding toy 2 from falling off the seat 3.

The protection frame 26 is detachable at its front portion with respect to the steering handle 8, and its rear portion is attached through mounting holes 27 and 28 provided in the rising portions 20 and 21 of the locking member 12. Shaft 29
Are fixed to the locking member 12 by penetrating these portions.

Thus, as shown in FIGS. 1 and 2, a state in which the locking device 1, the riding toy 2 and the protection frame 26 are combined is realized. In this state, the front wheel 5 and the rear wheel 6 are suspended in the air, and therefore, as shown in FIG. 1, the locking member 12 moves around the shaft 11 with respect to the base member 10 as shown by an arrow 30 as shown in FIG. Locking operation can be performed. At each end of the locking operation, a force for locking in the opposite direction is exerted by the action of the compression spring 22, so that a shock that may occur at each end of the locking operation is reduced or prevented. With the locking operation of the locking member 12 described above, the riding toy 2 and the protection frame 26 are locked as indicated by an arrow 31 in FIG. In FIG. 1, one posture taken in the rocking operation of the riding toy 2 is shown by imaginary lines.
