Description

[Detailed description of the invention] The present invention relates to a front axle holding structure for a children's play vehicle, and is particularly suitable for this type of vehicle equipped with a body made of synthetic resin, so that anyone can easily assemble the front axle to the body. In addition to making the work easier and more accurate, the front axle can be held extremely stably and robustly by the body, and consideration has been given to prevent accidents such as cracks in the body. To explain the specific configuration of the present invention based on an example, the first vehicle represents a car for children as a play vehicle.
~ In Figure 4, 1 is a body made of hard synthetic resin such as polypropylene, and an upper body 2 and a lower body 3, which are separately molded in advance, are removably fitted into each other at opposing opening edges. By putting them together, the whole is assembled into a box-like shape that looks like a middle-class sweets.

A front axle 4 is assembled and held on the bottom surface of the lower body 3 of the body 1 in the following manner.

Namely, numeral 5 denotes four front axle holding grooves formed integrally with the molding of the lower body 3 on the front bottom surface thereof, and as is clear from the figure, the lower and side sides are open. The side opening faces into and communicates with the inside of the front wheel fender 6.

As suggested from the enlarged view of FIG. 5, this holding groove 5 is
It is formed in advance integrally with the lower body 3 so that a part of the bottom surface itself of the lower body 3 is bent into a substantially vertical U-shape in cross section, and therefore the inside of the body 1 (lower body 3 Therefore, it can be said that a so-called lip that reinforces the front bottom surface of the lower body 3 is useful.

The holding grooves 5 are separately arranged as a left and right pair parallel to each other with a central notch 7 in the front bottom surface of the lower body 3 as a boundary.

However, as long as the front axle 4 can be held as a groove 5 that is formed integrally with the body 1 on the bottom surface and is open on the lower and side sides, the holding groove 5 can be used as a part of the bottom surface as described above. Instead of forming it in the form of a target bulge, it is also conceivable to partially thicken the bottom surface of the body 1 so as not to bulge out due to the total heat, and to form the holding groove 5 in the form of a cutout of the thick part. .

The front axle 4 is fitted into such a holding groove 5 from below in a horizontally extending state extending through the pair of left and right sides thereof.
As a result, it is restrained to the bottom surface of the lower body 3 so that it cannot be displaced.

In that case, in FIGS. 1 to 5, a fixing piece 8 is joined from below to the bottom of the lower body 3, and the fixing piece 8 is fixed to the bottom with bolts 9 to prevent the front axle 4 from falling off. This is only one example of a fixing means, and therefore, it may be directly fixed to the bottom surface of the lower body 3 by passing the bolt 9 to the front axle 4 as shown in FIG.

In short, as the front axle 4 is held by the groove 5,
By being fitted into the interior, the same effect can be achieved as long as positional displacement is restricted.

In this sense, the cross-sectional shape of the front axle 4 may be circular or square, and the material is not limited to metal, but may also be made of synthetic resin or other materials as long as it has the same strength. It is.

Both left and right ends of the front axle 4 pass through the side openings of the holding groove 5,
The front wheel fender 6 has an arcuate concave shape formed in the body 1 and projects into the front wheel fender 6, and the front wheels 10 are located at both ends of the projecting part.
L-shaped knuckle arms 11 are each pivotally connected in an upright penetrating state.

12 is a retaining ring for the arm 11, and 13 is a steering control plate fixedly integrated with the center of the front axle 4, and the lower end of the steering wheel shaft 14 is rotatably attached to the protruding rear end of the steering control plate. Insertion is locked.

Reference numeral 15 denotes a rotating projecting piece that integrally projects rearward from the middle part of the handle shaft 14, and a locking pin 16 is implanted at the projecting rear end.

Reference numeral 17 denotes a tie rod that connects the left and right pair of the knuckle arms 11, the central bent portion of which is engaged with the locking pin 16, and the left and right end portions of the tie rod that connect the left and right pairs of the knuckle arms 11. It is pivotally connected to the bending piece 18 of.

Further, reference numeral 19 is a concave-shaped support mast fixedly installed in the mutual internal space between the front ceiling surface of the upper body 2 and the front bottom surface of the lower body 3, and its upright portion extends inward toward the front wheel fender 6. By being brought into contact with the upper and lower bodies 2 and 3, the upper and lower bodies 2 and 3 are stretched to prevent distortion and deformation in the longitudinal and lateral directions.

Reference numeral 20 designates an adjustment slot formed at the lower end of the support mast 19, 21 a fixing bolt at the upper end, 22 a pedal mounting bar horizontally suspended on the support mast 19, and 23 a pedal.

As described above, in the present invention, when assembling and holding the front axle 4 on the body 1 molded from synthetic resin, the bottom surface of the body 1 is integrally formed with the holding groove 5 which is open on the lower and side sides. In order to fit the front axle 4 into the concave groove 5 in a penetrating state, for example, the front axle is simply assembled and fixed with bolts and nuts on the bottom of the flat body. Compared to the configuration, anyone can assemble the front axle 4 to the body 1 very easily and correctly.However, after assembly, the front axle 4 is held in the holding groove 5 so that it cannot be displaced. Therefore, it is possible to maintain an extremely stable and robust fixed state, and it is also possible to completely prevent cracks in the body 1 and unauthorized movement of the front axle 4 that spread from the fixed parts such as bolts.

Furthermore, since the front axle holding groove 5 is molded integrally with the body 1, it can not only be expected to be effective in mass production, but also reinforce the bottom surface of the body 1, which is a distant relative of the above effect. Synergistic.

Of course, when the size of the front wheels 10 is constant, the height of the body 1 above the ground can be lowered.

Furthermore, if the holding grooves 5 are arranged separately as a pair of left and right, the steering regulating plate 13 and the tie rod 17 can be arranged with respect to the front axle 4.
If such a mechanism can be rationally attached, and both left and right ends of the front axle 4 extend into the front wheel fender 6, and the knuckle arm 11 of the front wheel 10 is pivotally held by the projecting ends, then The assembly structure can be significantly simplified, and it can be said to be a highly profitable invention.
