Description

[Detailed description of the invention] [Industrial application field] This invention relates to riding toys, and in particular,
This invention relates to a riding toy equipped with a cushion mechanism.

[Prior Art] Ride-on toys for children to ride and play are generally
The vehicle includes a vehicle body, and rotatable front wheels and rear wheels that are disposed below the vehicle body and support the vehicle body. A seat for a child to sit on is formed on the top surface of the vehicle body. In front of the seat, a handle post with a grip for the child is provided and projects upward from the vehicle body.

Such a riding toy is driven by a child sitting on a seat and kicking the ground with both feet while holding the handle with the child's hands. The grip portion is fixedly provided to the handle post, and some grip portions are fixed to the vehicle body, and may also serve as a steering handle. When the grip part also serves as a control handle, the rotation operation causes the handle post to rotate around its axis, changing the direction of the front wheel connected to the handle post, and changing the direction of the ride-on toy arbitrarily while driving. can be changed.

[Problems to be solved by the invention] However, the above-mentioned riding toys have
Those equipped with a cushion mechanism that can absorb the shock received from the wheels while driving are
Previously, this was not the case at all.

Therefore, this invention aims to provide a riding toy equipped with a cushion mechanism.

[Means for Solving the Problems] This invention is a riding toy comprising a vehicle body and rotatable front wheels and rear wheels disposed below the vehicle body and supporting the vehicle body, and which solves the above-mentioned problems. is solved as follows.

The axles of the front wheels and the rear wheels are attached to the lower ends of struts extending downward from the vehicle body.
The strut includes a first tubular member and a second tubular member that slidably fits onto the inner peripheral surface of the first tubular member in a telescoping manner. A first spring receiving wall extending from the inner peripheral surface of the first tubular member is provided in the space defined by the first tubular member, and the space is defined by the second tubular member. A second spring receiving wall extending from the inner peripheral surface of the second tubular member is provided within the space. A cushion spring is disposed between the first spring receiving wall and the second spring receiving wall, and acts in a direction to pull the first and second tubular members apart from each other. Furthermore, the first spring receiving wall is provided at a position offset from the longitudinal center of the first tubular member, and the first spring receiving wall is provided at a position offset from the longitudinal center of the first tubular member, and the first and second tubular members are mutually disposed in a state in which the cushion spring is accommodated. The overlap length can be adjusted in two stages,
The first tubular member can be fitted into the second tubular member from either side of each end thereof.

[Operations and Effects of the Invention] According to this invention, the length of the support column is changed by changing the overlapping length of the first and second tubular members. On the other hand, the cushion spring exerts its elasticity in a direction in which the first and second tubular members are pulled apart from each other, ie, in a direction in which the length of the strut is lengthened. Therefore, the action of shortening the length of the strut is opposed by the force of the cushion spring. Therefore, the impact received from the wheels on the vehicle body can be weakened.

As described above, when a cushion mechanism is added to a riding toy, the riding toy becomes superior in ride comfort, and is particularly effective for general play on the road.

Further, according to this invention, while maintaining the above-mentioned cushioning effect, the overlapping lengths of the first and second tubular members can be adjusted in two stages simply by changing the orientation of the first tubular member. Therefore, it becomes possible to adjust the height of the vehicle body and the seat from the ground or floor surface. At this time, since the first tubular member is used in either of two height-adjustable states, problems such as missing parts that may occur if separate parts are required for height adjustment are avoided. do not have.

In this way, this invention can broaden the age range of children who can ride on the toy compared to conventional riding toys. For example, if the lowest height obtained by height adjustment is set lower than conventional ones, a riding toy that can be enjoyed by children of a younger age can be obtained. In this way, if the age range of children who can ride on the toy is broadened, one riding toy can be used for a long time, and it can be said to be economically superior.

[Embodiment] An embodiment of this invention will be described with reference to FIGS. 1 to 5.

This riding toy 1 has an appearance as shown in FIG. This riding toy 1 includes a vehicle body 2,
It includes rotatable front wheels 3 and rear wheels 4 which are arranged below the vehicle body 2 and support the vehicle body 2.
On the top surface of the vehicle body 2, there is a seat 5 for a child to sit on.
is formed. In front of the seat 5, a handle post 7 is provided that projects upward from the vehicle body 2 and includes a pair of grips 6 (only one of which is shown) for the child. Note that the number and shape of the grip portions 6 are arbitrary. In this embodiment, the handle post 7 has a shape imitating the neck of an animal such as a "bear", but it may have a simple columnar shape. A hand handle 8 is provided at the rear end of the vehicle body 2.

The riding toy 1 has both front wheels 3 and rear wheels 4,
Each is equipped with a cushion mechanism, and
As shown in FIG. 2, a so-called height adjustment mechanism that can lower the height of the vehicle body 2 is also employed.

As shown thirdly, the handle post 7 is rotatably held relative to the vehicle body 2 about a vertically oriented axis. The front wheel 3 includes an axle 9, which is attached to the lower end of a strut 10 that is directly below the handle post 7 and extends downward from the vehicle body 2. The strut 10 includes a first tubular member 11 and
The second tubular member 12 is slidably fitted onto the inner peripheral surface of the first tubular member 11 in a nested manner.

The handle post 7 has a hollow cylindrical lower end, and a flange 13 is formed extending outward from the cylindrical lower end. A portion below the flange 13 is fitted into a relatively large diameter portion of the upper half of a cylindrical seat 14 formed on the vehicle body 2, and is rotatably held. At this time, the lower half of the seat 14 and the lower end of the handle post 7 form a uniform inner peripheral surface.

The first tubular member 11 has a cylindrical shape as a whole, and a flange 15 projecting outward is formed at a position that bisects its longitudinal dimension.
Further, a spring receiving wall 16 is formed inside the cylinder of the first tubular member 11 . The spring receiving wall 16 is formed at a position offset from the center of the first tubular member 11 when viewed in the longitudinal direction of the first tubular member 11, that is, at a position offset toward the lower side when viewed in FIG. The first tubular member 11 is also provided with two selectively used mounting holes 17 and 18 at vertically symmetrical positions. Third
In the state shown in the figure, the set screw 19 is inserted into one of the mounting holes 17, and the other mounting hole 18 remains open. Further, guide pin insertion holes 20 are provided in the first tubular member 11 at approximately equal distances with the spring receiving wall 16 as the center.
and 21 are provided. These guide pin insertion holes 20 and 21 are selectively used to receive the guide pin 22, and in the state shown in FIG. 3, the guide pin 22 is received in the guide pin insertion hole 21 located below. There is. The upper guide pin insertion hole 20 remains open. Furthermore, a notch 23 is formed in the upper end of the first tubular member 11 according to FIG. This notch 23 is
This is provided to allow cushioning action in the state shown in FIG. 4, which will be explained later.

The first tubular member 11 having such a configuration is inserted into the seat 14 and the lower end of the handle post 7 from below. Then, the set screw 19 is inserted into the mounting hole 17 and a mounting hole provided at a corresponding position on the handle post 7 (not shown), and the handle post 7 and the first tubular member 11 are mechanically fixed. At this time, the flanges 13 and 15 are
The seat 14 of the vehicle body 2 is sandwiched from above and below, and the handle post 7 and the first tubular member 11
The assembly consisting of the above is prevented from slipping out of the vehicle body 2.

The second tubular member 12 includes a cylindrical portion 25 having a spring receiving wall 24 near its upper end. The aforementioned axle 9 is held by this cylindrical portion 25. The cylindrical portion 25 is provided with a guide hole 26 extending in the vertical direction. An arm 27 is formed extending diagonally downward from the cylindrical portion 25, and a fall prevention roller 28 is provided at the free end of the arm 27.
is installed.

The second tubular member 12 is constructed by inserting the cylindrical portion 25 of the second tubular member 12 into the first tubular member 11 from below with the arm 27 directed forward. It is fitted into the tubular member 11. At this time, a cushion spring 29 made of, for example, a coil spring is inserted so as to be sandwiched between the spring receiving wall 16 and the spring receiving wall 24. Then, the guide pin 22 is inserted so as to pass through the guide hole 26 and one of the guide pin insertion holes 21. In this state, the second tubular member 12
is prohibited from rotating around its axis with respect to the first tubular member 11, but in the vertical direction, the range in which the guide hole 26 extends or the second tubular member 12 is
Only the range up to where the upper end surface comes into contact with the spring receiving wall 16 is allowed. At this time, the cushion spring 29
acts and exerts an appropriate cushioning action on the front wheel 3.

The state shown in FIG. 3 described above corresponds to the state shown in FIG. 1 in which the vehicle main body 2 is at a relatively high position. The state in which the height of the vehicle body 2 shown in FIG. 2 is lowered is as shown in FIG.
This is achieved by orienting the first tubular member 11 of the strut 10 upside down. At this time, set screw 1
9 is attached so as to pass through the attachment hole 18. Further, the guide pin 22 is provided so as to pass through the guide pin insertion hole 20. in this way,
When the first tubular member 11 is oriented upside down,
The effective length of the first tubular member 11 is shortened and the strut 1
The overall length of 0 is shortened and the vehicle body 2 is brought to a lower position.

Even in the state shown in FIG. 4, the cushioning action by the cushioning spring 29 is working. The aforementioned notch 23 allows the arm 27 to move between the first tubular member 11 and the arm 27 when the second tubular member 12 moves up and down relative to the first tubular member 11 as a result of the cushioning action.
This is to avoid interference with the

As shown in FIGS. 3 and 4, the column 10
is held rotatably about a vertical axis with respect to the vehicle body 2 together with the handle post 7. Therefore, when a child sitting on the seat 5 grips the grip part 6 with his/her hand and rotates the handle post 7, this is transmitted to the support column 10, and the direction of the front wheel 3 is changed. Thereby, the traveling direction of the riding toy 1 can be changed. The fall prevention roller 28 is provided to prevent the ride-on toy 1 from falling forward, and it always follows the movement of the handle post 7 so that it faces in the direction of movement of the front wheels 3. Follow it and change its position.

In this embodiment, the above-mentioned cushion mechanism and height adjustment mechanism are also provided in connection with the rear wheel 4, and care has been taken so that common parts can be used on the rear wheel 4 side as well. has been done. FIG. 5 shows the configuration of this rear wheel 4 side.

FIG. 5 shows the vehicle body 2 in a relatively high position, as shown in FIGS. 1 and 3. Here, the first tubular member 11, the second tubular member 12, and the cushion spring 29 constituting the above-mentioned support column 10 are commonly used, so corresponding parts have the same reference numerals. , and duplicate explanations will be omitted.

The configuration related to the rear wheel 4 shown in FIG. 5 differs from the front wheel 3 side only in the following points. That is, the first tubular member 11 is inserted into a seat 30 provided at the rear of the vehicle body 2 and fixed to the vehicle body 2 by a set screw 19 . In other words, the first tubular member 11 does not need to be rotatable relative to the vehicle body 2. Further, the second tubular member 12 is inserted into the first tubular member 11 with its arms 27 facing rearward. Thereby, the fall prevention roller 28 prevents the riding toy from falling backward. The second tubular member 12 holds the axle 31 of the rear wheel 4. The other configurations are the same as those on the front wheel 3 side. Therefore, when it is desired to lower the height of the vehicle body 2, the first tubular member 11 is oriented upside down.

In addition, as in this embodiment, the front wheel 3 side and the rear wheel 4 side
It goes without saying that common parts may not be used for each side, but unique parts may be used for each side.

Further, in the above embodiment, the support 10 is connected to the vehicle main body 2.
The front wheels 3 are held rotatably relative to each other, and the direction of the front wheels 3 is changed according to the rotation.
This invention can also be applied to riding toys in which the prop is fixed to the vehicle body and the direction of the front wheels cannot be changed.

Further, in the above-described embodiment, the support column 10 was constructed by a combination of two tubular members, the first tubular member 11 and the second tubular member 12. It may be added to constitute a support.

In addition, as a preferable example, the cushion spring is
Although a coil spring is shown as an example, other types of springs may be used.
