Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a children's vehicle, and more particularly to a children's vehicle that has been improved to allow a wide variety of uses.

BACKGROUND ART Some children's vehicles have two front wheels and two rear wheels, and for example, the front wheels can be turned by bundle operation.

Children's vehicles with such convertible front wheels are advantageous in developing children's motor and coordination skills.

However, for infants who are still young, a structure in which the front wheels can be turned is undesirable from a safety standpoint.

Therefore, it is desirable to have a structure that cannot be converted when the child is still young, and to have a structure that can be converted as the child grows up.

For this reason, it is preferable that the above-mentioned two states can be selected for one children's vehicle, and furthermore, it is desired that the effort for making this selection is simple.

Also, as another kind of children's rides like this,
Some vehicles have a handle at the rear of the vehicle for pushing by hand.

This handle is used, for example, when a child is placed on the children's vehicle and an adult pushes the child from behind, or when the child pushes the child's vehicle himself.

Considering the manner in which such a handle is used, it is not preferable for the front wheels to be configured to be able to turn as described above from the viewpoint of operation method, and therefore, the front wheels are always configured to be non-turnable.

However, if this handle is easily removable, when the hand-operated vehicle is no longer used, the handle can be removed and the child's vehicle transformed into a sleek appearance. Dew.

Now, if it is transformed into a children's vehicle with a smart appearance as described above, children will certainly be happy with this fact.

However, when transformed in this way, the children's vehicle is already in a position where the child can only operate it with his or her own knife.

If so, the child will now be able to maneuver more freely,
That is, it would be desirable to be able to turn the front wheels by means of a bundle.

Therefore, the main object of the invention is to provide a children's vehicle that is equipped with the above-mentioned features or that is capable of the various uses mentioned above.

The feature of this invention is "means for selectively fixing" the rotation of the bundle shaft.

The bundle shaft is rotatably received in a cylindrical portion formed at a relatively front portion of the vehicle body.

The "selective fixing means" includes (1) a "fixing member" held on the bundle shaft side and detachably attached to the bundle shaft, and (2) the "fixing member" formed on the vehicle body side. and an ``engaging portion'' that engages with the bundle shaft and prevents the bundle shaft from rotating relative to the cylindrical portion.

According to this invention, a single children's vehicle can be used in a manner in which the handle is pushed with the front wheels disabled, and in which the handle is removed and the front wheels can be turned so that the child can steer the vehicle. becomes.

Other objects and features of the present invention will become clearer from the detailed description given below with reference to the drawings. FIG. 1 is an external perspective view of one embodiment of the present invention.

FIG. 2 is a sectional view of FIG. 1. FIG. 3 is an exploded perspective view showing an embodiment of the essential elements of the present invention.

FIG. 4 is a sectional view showing the combined state of the elements shown in FIG. 3.

With reference to FIGS. 1 and 2, the children's vehicle includes a vehicle body 1 made of, for example, hard plastic.

A seat 2 is provided on the upper surface of the vehicle body 1 at a relatively rear portion thereof.

The seat 2 is preferably configured to be openable and closable, and appropriate items can be stored below the seat 2.

A bundle 3 is provided at a position where a child sitting on a seat 2 can operate it.

The bundle 3 is held against the vehicle body 1 by a bundle shaft 4.

The configuration related to this bundle shaft 4 will be described later.

A front axle 5 is held at the lower end of the bundle shaft 4, and front wheels 6 are rotatably provided at both ends of the front axle 5, respectively.

A rear axle 7 is supported at the rear of the vehicle body 1, and rear wheels 8 are provided at both ends of the rear axle 7, respectively.

A handle 9 is provided to protrude upward from the rear end of the vehicle body 1.

The handle 9 is used when pushing this children's vehicle from behind, and is configured so that it can be removed from the vehicle body 1 when it is no longer needed.

That is, the rod-shaped body 9a of the handle 9 facing in the vertical direction is simply inserted into the hole 1a provided in the vehicle body 1.

FIG. 2 shows how the bundle shaft 4 is attached.

Referring to FIGS. 2, 3, and 4, the bundle shaft 4 is composed of an upper tube 10, an intermediate shaft 11, and a lower block 12. As shown in FIG.

The aforementioned bundle 3 is thus fixed to the upper tube 10 and the front axle 5 is held to the lower block 12.

The upper end of the intermediate shaft 11 is inserted into the upper tube 10 and fixed to the upper tube 10 by a screw 13, and is fixed to the lower block 12 in advance.

In order to rotatably hold the bundle shaft 4, the vehicle body 1 is provided with a cylindrical portion 14.

This cylindrical portion 14 actually receives the intermediate shaft 11, and the upper and lower end surfaces of the cylindrical portion 14 are in contact with the lower end surface of the upper tube 10 and the upper end surface of the lower block 12, respectively. This prevents it from coming off.

A notch 15 is provided in the cylindrical portion 14 .

The cutout portion 15 is formed by cutting out the side wall of the cylindrical portion 14 by a predetermined angular range for reasons to be described later.

When the intermediate shaft 11 is inserted into the cylindrical part 14, the notch 1
A protrusion 16 is provided at a position such that the receptacle can be inserted into the receptacle 5.

The movement range of the protrusion 16 within the notch 15 is limited, so that the rotation range of the bundle shaft 4 is predefined.

This is done in consideration of safety and operability.

The following is a characteristic feature of this invention.

A through hole 17 is provided in the above-mentioned protrusion 16 in a direction intersecting the axis of the bundle shaft 4 .

A pin 18, such as a taper pin, is inserted into the through hole 17.

If a taper pin is used, it can be fixed simply by strongly driving it into the through hole 17.

The state in which the pin 18 is driven is clearly shown in FIG.

In FIG. 4, the pin 18 is in contact with both side edges of the notch 15.

Therefore, in this state, the intermediate shaft 11, that is, the bundle shaft 4, is prohibited from rotating relative to the cylindrical portion 14, that is, the vehicle body 1.

Here, the pin 18 constitutes the above-mentioned "fixing member", and both side edges of the notch portion 15 constitute the above-mentioned "engaging portion".

As described above, turning of the bundle 3 and the front wheels 6 is prohibited.

If a turning operation using the bundle 3 is desired, the narrow end of the pin 18 is driven in with a hammer and the pin 18 is pulled out from the through hole 17.

Accordingly, the bundle shaft 4 becomes rotatable within a predetermined rotation range, and the front wheel 6 can be turned by operating the bundle 3.

Various other variations are conceivable for selectively fixing the rotation of the bundle shaft 4.

This will be discussed below.

5 and 6 are views for explaining other examples of means for selectively fixing the rotation of the bundle shaft, with FIG. 5 being an exploded perspective view and FIG. 6 being a sectional view.

What is shown in FIGS. 5 and 6 is a slight modification of that shown in FIGS. 3 and 4 above, and corresponding parts are given like reference numerals, and the different parts are explained below. I will only explain about.

First, the cylindrical portion 14 has a through hole 19 extending through its side wall.
is provided.

A through hole 20 is also provided laterally through the intermediate shaft 11.

Note that the protrusion 16 is not provided with anything corresponding to the through hole 17.

In the above configuration, when the intermediate shaft 11 is inserted into the cylindrical portion 14, the protrusion 16 is received in the notch 15, and the through hole 19 and the through hole 20 are aligned.

Therefore, if the pin 21 is driven through the well-aligned through holes 19 and 20, then the intermediate shaft 11
That is, the bundle shaft 4 is fixed to the cylindrical portion 14.

Here, the pin 21 constitutes the "fixing member", and the periphery of the through hole 19 provided in the cylindrical portion 14 constitutes the "engaging portion".
Configure.

7 to 9 are diagrams for explaining still other examples of means for selectively fixing the rotation of the bundle shaft,
FIG. 7 is a partial sectional view of the children's vehicle, FIG. 8 is an exploded perspective view, and FIG. 9 is a sectional view.

In FIGS. 7 to 9, parts corresponding to those shown in FIGS. 1 to 4 are given the same reference numerals, and only different structures will be described below.

The cylindrical portion 14 is provided with another second notch 22 in addition to the notch 15 into which the protrusion 16 is received.

Both side edges of this second notch portion 22 constitute the above-mentioned “engaging portion”.

A key-shaped member 23 as the "fixing member" is prepared in correlation with the size of the notch 22.

This key-shaped member 23 is attached to the side of the intermediate shaft 11 with a screw 24.

This attached state is shown in FIG. 9, and as can be seen from FIG. 9, the key-shaped member 23 is tightly received in the second notch 22.

As described above, the intermediate shaft 11, that is, the handle shaft 4 is fixed to the cylindrical portion 14.

Then, when the screw 24 is removed with a screwdriver or the like, the key-shaped member 23 is separated and the handle shaft 4 becomes rotatable.

10 and 11 are views for explaining still another example of means for selectively fixing the rotation of the handle shaft, and FIG. 10 is a partial plan view of a children's vehicle. 11
The figure is a sectional view.

In FIGS. 10 and 11, parts corresponding to those shown in FIGS. 1 to 4 described above are given the same reference numerals, and different structures will be explained.

In the example shown here, the notch 15 and the protrusion 16 are not provided.

Instead, the overhanging portion 2 overhangs from the upper pipe 10.
5 is provided.

This projecting portion 25 is received in a fan-shaped recess 26 formed on the upper surface of the vehicle main body 1.

Therefore, the combination of the projecting portion 25 and the recess 26 defines the rotation range of the upper tube 10, that is, the handle shaft 4.

This projecting portion 25 is provided with a through hole penetrating into the vehicle body 1, and a pin 27 is driven into the through hole to fix the rotation of the handle shaft 4.

Here, the pin 27 constitutes the above-mentioned "fixing member", and the periphery of the through hole provided in the baby carriage main body 1 into which the pin 27 is received constitutes the above-mentioned "engaging portion".

12 and 13 are diagrams for explaining still another example of means for selectively fixing the rotation of the handle shaft, FIG. 12 is a perspective view of the main part, and FIG. 13 is a cross-sectional view. It is a diagram.

The example shown here should be understood to be a modification of the example shown in FIGS. 5 and 6.

Therefore, parts corresponding to those shown in FIGS. 5 and 6 are given the same reference numerals, and different structures will be explained below.

In this example, the through hole 19 shown in FIGS. 5 and 6,
20 is not provided.

Instead, the upper tube 10 is provided with a flange-like extension 28 .

This projecting portion 28 contacts the upper surface of the vehicle body 1.

The projecting portion 28 is provided with a through hole 29, and the vehicle body 1 is also provided with a through hole 30 so as to be aligned with the through hole 29.

With this configuration, when the pin 31 is driven through the through hole 29 and the through hole 30, the upper tube 10, that is, the handle shaft 4 is fixed.

Here, the pin 31 constitutes the "fixing member", and the through hole 30 constitutes the "engaging portion".

Still other examples may be considered as means for selectively fixing the rotation of the handle shaft.

As described above, according to the present invention, there is a mode of use in which the front wheel cannot be turned with the handle for manual pushing attached;
Both the use mode in which the front wheels can be turned with the handle removed and the use mode in which the front wheels can be turned are made possible for one child's vehicle.

Therefore, the mode of use can be appropriately selected according to the child's growth, and this is possible for one child's vehicle, which is very economically advantageous.
