Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved body assembly structure for a button on a play vehicle for children.

Conventionally popular children's play cars have a synthetic resin body that is only shaped like an upright U-shape with an opening at the bottom, which results in poor body strength.
In the case of this type of automobile, the left and right sides of the body surrounding the seating opening are usually used as handrails, etc., and when a strong downward force is applied from above to these handrails, etc. The entire body is malformed,
It is particularly prone to distortion in the lateral direction, which causes cracks to occur from the lower edge of the opening, and if even a slight unevenness is formed on the lower edge of the opening, cracks are likely to occur. In any case, the safety of the undercarriage is unavoidable, with children injuring their legs or tearing their socks, and it is not easy to make the body itself two-tone, which is a cause for concern.

In this regard, there are some structures in which the upper and lower bodies are joined by a button on the metal body with flanges that extend horizontally outward, but in this case, both flanges simply form a horizontally joined palm shape. Therefore, sufficient assembly rigidity cannot be maintained unless both joining flanges are further fixed with bands, bolts, etc., which causes another problem in that the assembly work of the body becomes complicated.

The present invention has been devised to solve these problems with a simple structure that does not increase costs, and the specific structure will be explained based on the illustrated embodiment.
It is as follows.

That is, in the external view of FIG. 1, which shows a car for children as an example of a play vehicle, A indicates an upper body having a generally inverted U-shaped cross section as a whole, and B has a generally U-shaped cross section as a whole. The lower body is made of polypropylene or other hard synthetic resin material and is integrally molded from polypropylene or other hard synthetic resin material.

As is clear from FIGS. 2 to 4, the upper body A is provided with a seating opening 1 approximately in the center thereof, and the opening 1 is provided in the upper body A.
It is defined so as to be substantially surrounded by a standing wall 2 which is bent and suspended from the top surface of the building.

In this case, the standing wall part forming the rear side of the seating opening 1 functions as a backrest as it is, and the top part partitioning the front side of the opening 1 also has a steering wheel shaft 3.
A through hole 4 is opened.

Reference numeral 5 denotes a seat mounting wall extending horizontally from the surrounding standing wall 2 so as to block a portion of the rear side of the seating opening 1, and a cushion seat 6 is mounted on the wall.

In that case, the seat mounting wall 5 as suggested from the figure
is integrally suspended considerably lower than the fitting height plane of the lower edge of the opening of the upper body A and the upper edge of the opening of the lower body B, which will be described later, so as to penetrate into the hollow interior of the lower body B. There is.

Reference numeral 7 denotes a pair of left and right light mounting tubes located at the front of the body A and extending from the top surface thereof, into which headlights 8 are fitted in the form of lids.

On the other hand, as shown in FIGS. 2 to 4, the lower body B has an operating opening 9 located approximately in the center of its bottom surface and corresponding to a position approximately directly below the seating opening 1.

Reference numeral 10 denotes a pair of left and right front wheel fenders 111, which are also formed on the lower body B. A groove for inserting the front axle 12 is provided on the bottom surface of the lower body B so as to cross between the two fenders 10. , 13 are a pair of left and right rear wheel fenders that are recessed into the lower body B, and the rear center of the lower body B that occupies between them is connected as a so-called raised bottom type joint wall 14. There is.

This joining wall 14 faces directly below the seat mounting wall 5 and supports the mounting wall 5 from below, but in addition to providing mere contact support, it also supports the required number of both walls 5 and 14. It is preferable to fix with bolts 15 or the like.

It is a support wall for the rear axle that is separated between the joint wall 14 of the 16-bar and both rear wheel fenders 13, and in this case, the fender 13 and the joint wall 14 are both formed from the bottom. Therefore, the pair of left and right sides of the support wall 16 protrude downward relative to the support wall 16.

Reference numeral 17 denotes a pair of left and right rear axle insertion grooves provided in the center of both support walls 16, into which the bearings 19 of the rear axle 18 are respectively fitted.

The lower edge of the opening of the upper body A and the upper edge of the opening of the lower body B are set to a size that substantially corresponds to each other so that they can be attached and detached. , 4, it stands up as an annular collar piece 20.

Similarly, as shown in FIGS. 3 and 4, the lower edge of the opening of the upper body A is suspended as an annular collar piece 21 that can be attached to the collar piece 20 of the lower body B from the outside. A plurality of clamping pieces 22 constituting a groove S are also suspended from the inner side of the flange piece 21.

First, the lower edge of the opening of the upper body A is formed into a partial bifurcated shape by the outer collar piece 21 and the inner clamping piece 22 at a plurality of scattered locations. The opening edges of both bodies A and H are configured to fit together from the vertical direction so that the above-mentioned flange piece 20 related to the upper edge of the opening of lower body B can be held horizontally from both inside and outside sides. It is.

In this case, in the illustrated example, the clamping pieces 22 of the upper body A are provided in a plurality of stages over the entire vehicle, including the left and right sides and the front and back sides of the vehicle, and are scattered in multiple stages. It is also possible to limit the installation locations to, for example, only the left and right sides of the vehicle.

In addition, in the case of FIGS. 2 to 4, the clamping piece 22 is set to hang down from the lower edge of the opening of the upper body A to clamp the annular collar piece 20 of the lower body B, but on the contrary, as shown in FIG. As shown in FIG. 6, a similar clamping piece 22 is placed upright on the upper edge of the opening of the lower body B, and the annular collar piece 21 of the upper body A is held from both the inside and outside by the clamping piece 22 and the collar piece 20. It may be set so that it can be held.

In the illustrated example, the lower edge of the opening in the upper body A and the upper edge of the opening in the lower body B can be freely attached and detached by a required number of bolts 23 passing through in the longitudinal direction only at the front and rear sides of the vehicle. Although the buttons are fixed in place, and the left and right positions are limited to fitting the upper and lower bodies A and B through the clamping pieces 22, even if the buttons are placed in these positions, the required number of bolts must be passed through them laterally. Therefore, both the upper and lower bodies A.

The assembly strength of B may be further improved.

In the lower body B shown in FIG. 5.6, the outer annular collar piece 20 is turned outward and further bent down to function as a bumper or fender.

Figures 7 and 8 show the overall assembled state of the infant vehicle including the body of the present invention, and inside the upper and lower bodies A and B assembled as described above, there is a metal structure at the front position of the vehicle. A substantially channel-shaped support mast 24 is erected and buttoned, and the top surface of the mast 24 is joined to the ceiling surface of the upper body A, and is removably fixed with a required number of bolts 25. The bottom surface is joined to the bottom surface of the lower body B, and is also fixed with a required number of bolts 26.

Since both left and right side surfaces of this support mast 24 are in contact with or fixed to the front wheel fender 10 from the inside, this mast 24 supports both the upper and lower bodies A.

It acts as a rigid bracing body for the distortion that occurs in the longitudinal and lateral directions of B.

Similarly, in the rear position of the vehicle, the seat mounting wall 5 hanging down from the upper body A is connected to the clamping piece 22 between the lower edge of the opening of the upper body A and the upper edge of the opening of the lower body B. The button is placed at a lower height surface that penetrates into the hollow interior of the lower body B than the fitting height surface, and is supported from below by the joint wall 14 of the lower body B. Coupled with the fitting of both bodies A and B, it is possible to assemble both bodies A and B easily, smoothly, correctly and reliably. , it can be supported stably, and its assembly rigidity can also be improved.

Moreover, the two standing walls of body A serve as a backrest for the infant, and the top surface of body A serves as a so-called handrail.
It also means that each word can be used in other words.

In addition, as shown in the figure, 27 is a pair of left and right front axle fixing pieces, 28 is also a rear axle fixing piece, 29 is the above-mentioned steering mechanism installed at the bottom of the steering shaft 3 so as to be interlocked, 30 are a pair of left and right pedals suspended from the mast 24, and are connected to the crank part of the rear axle 18 and the swing arm 3.
They are each pivotally connected via 1.

As described above, in the body assembly structure of a children's play vehicle according to the present invention, the upper body A and the lower body B are integrally molded separately from each other from a synthetic resin material, and the lower edge of the opening of the upper body A When assembling the upper edge of the opening of lower body B, the lower edge of the opening of upper body A is shaped into a bifurcated shape by buttoning the lower edge of the opening at multiple locations, thereby forming the upper edge of the opening of lower body B. Either it can be held horizontally, or the upper edge of the opening of the lower body B can be made into a bifurcated shape with buttons at multiple locations, so that the lower edge of the opening of the upper body A can also be held horizontally. , a seat mounting wall 5 whose opening edges are fitted in the vertical direction and which penetrates into the hollow interior of the lower body B beyond the fitting height surface is suspended from the upper body A, and the mounting wall 5 is fitted into the above-mentioned fitting. Since the button is placed at a height lower than the mating height and supported from below by the joint wall 14 provided on the lower body B, the following effects can be achieved.

That is, the fitting operation of the opening edges of the upper and lower bodies A and B is performed from the vertical direction, and the clamping action by the forked portions is performed from both the inner and outer sides in the horizontal direction. Because it is configured to occur in multiple locations scattered around, the forked part is only formed on one side of the body,
The fitted positioning state can be easily obtained without any particular restrictions, and both bodies A and B can be assembled with extremely high efficiency.

In this respect, if the entire opening edge is shaped like a fork,
Even if it is applied only to one body side, and even if it is fitted and operated from the vertical direction,
It is difficult to obtain a positioning and matching state of the clamping action of the bifurcated parts over the entire length, and it is inevitably necessary to perform complicated operations.

The bifurcated shape extending over the entire length also makes the opening edge of the body rigid, making it difficult to perform the matching operation.

1. In the conventional example mentioned at the beginning, in which the crank extends horizontally from both the upper and lower bodies and band rings are fitted to both flanges after the palms are joined, a band ring separate from the body itself is required. Of course, even if the body is made of synthetic resin, the band ring usually has a U-shaped cross section throughout, and it is fitted from the horizontal direction, so the matching condition is difficult. It will be extremely difficult to obtain this.

It is not possible to assemble it as easily and correctly as in the present invention.

If the band ring can be fitted easily, the flanges and the band ring may become misaligned or come off.

In this sense, although the present invention can be assembled very easily and correctly as described above, it has excellent machinability that will never cause misalignment, separation, improper deformation, cracking, etc. in the assembled state.
It is distinctive in that it provides stabilization.

First, the opening edges of both the upper and lower bodies A and H are kept in a fixed state by the inner and outer clamping action from the horizontal direction by the fork, so that the fitting operation can be performed from the vertical direction. This also means that the band ring, bolt, nut, etc. mentioned above are not indispensable in order to prevent the band from slipping off or coming off.

Even if the outermost edges of both the upper and lower bodies A and B collide with other objects, this will not cause them to come off, nor will they be displaced.

In addition, even if the left and right sides of the top surface of the upper body A are used as handrails, and a downward force is applied to these positions,
Assembling rigidity sufficient to withstand this is maintained, and the bodies A and B do not undergo unauthorized deformation or cracks such as distortion in the horizontal direction.

Furthermore, a seat mounting wall 5 that enters into the hollow interior of the lower body B at 1 above the fitting height plane of the opening edges together hangs down from the upper body A and is buttoned, and the seat mounting wall 5
The button is located at a height lower than the fitting height surface and is supported from below by the joining wall 14 of the lower body B, so that when the opening edges are fitted together, the upper body Seat mounting wall 5 of A - quickly lower body B
By entering the hollow interior, not only can the above-mentioned assembly work be made smoother and positioning easier to match, but also the seating part, which requires the most assembly rigidity during use, can be fixed to both the upper and lower bodies. A and B can be strengthened without making them particularly thick, and the infant can be kept in a stable seated state.

The supporting position of the seat mounting wall 5 by the joining wall 14 is higher than the fitting height surface of the opening edges with the lower body B.
Since it is a low-height surface that fits in, it can effectively prevent the above-mentioned mating height surface from being adversely affected by the movement of a seated infant, etc., and the necessary components include both bodies A, It is sufficient to integrally mold body B, and it is also possible to make bodies A and H two-tone with the colored resin, so it can be said to be a highly profitable idea.
