Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a toy car in which drive wheels can be selected.

(Prior Art) In a car toy that uses a mainspring unit in which a mainspring and a plurality of gears are linked and arranged inside one case, and an axle is fixed to the final gear, the mainspring unit is usually attached to the rear wheel. In many cases, it is configured to drive the By the way, it seems that converting such a rear wheel drive system to a front wheel drive system can be easily done by reversing the direction and mounting position of the spring unit. In a toy car, the front part of the car body is formed lower than the rear part, so the space for accommodating the internal spring unit is also smaller at the front part. For this reason, if the spring unit has the same shape and you try to change the drive system by reversing its direction or mounting position, the replaced spring unit will stick out and not fit properly in the car body, or the axle will be in an unbalanced position. I feel relaxed. Therefore, unless the spring unit is made considerably smaller than the size of the toy itself, it is not possible to change the drive system simply by changing the direction or mounting position. If you make the mainspring unit smaller, the driving force will also be smaller, so
This is not practical because it reduces the fun of driving by half.

(Technical problem of the invention) This invention was developed in view of the above circumstances, and its technical problem is to provide a toy car whose drive system can be easily changed.

(Means for Solving the Problems) In order to solve the above problems, the toy car according to this invention that can convert the drive system has a chassis, a first spring unit, a second spring unit, and non-driving wheels having the following configuration. It is characterized by comprising a holder.

(a) The chassis shall be installed so that it can be attached to and detached from the vehicle body.

(b) For the above-mentioned chassis, there is a first spring unit that holds and drives the front wheels, a second spring unit that holds and drives the rear wheels, and a non-driving wheel holder that holds the non-driving wheels. Any two of them are selectively detachable.

(c) The front and rear parts of the chassis are formed with engaging parts that engage with and disengage from the engaging parts formed at the front part of the first spring unit and the rear part of the second spring unit, respectively. , and the non-driving wheel holder is formed with an engaging portion that engages with and disengages from each of the engaging portions formed on the front and rear portions of the vehicle chassis.

(d) The central part of the vehicle chassis is provided with an engaging part at the rear of the first spring unit, an engaging part at the front of the second spring unit, and both ends of the non-driving wheel holder. A common engagement part that can be removed is formed.

Embodiment An embodiment of this invention will be described below with reference to the drawings.

In the figure, the symbol A indicates a toy car. This car toy A includes car bodies 1 each formed separately.
It is constructed by appropriately selecting and assembling a chassis 2, a first spring unit 3, a second spring unit 4, and a non-driving wheel holder 5.

The chassis 2 is detachably attached to the vehicle body 1, and internally holds a first spring unit 3 for driving a front wheel a, a second spring unit 4 for driving a rear wheel b, and a non-driving wheel c. A storage section 8 for the wheel holder 5 is formed, and axle bearing grooves 9 and 10 for the front wheel a and rear wheel b are formed by cutting out grooves 9 and 10 on both front and rear walls of the storage section 8, respectively, and at the upper center end of the both walls. Engagement protrusions 12, 1 are provided on both sides as a common engagement part.
2, and the lower ends of the front and rear walls have engaging grooves 13 and 14 as engaging parts, and the upper end has screw receiving grooves 1 of the vehicle body 1.
A screw hole 16 corresponding to 5 is formed.

The first mainspring unit 3 has a mainspring (not shown) and a reduction gear connected in a case 18 having half the length of the storage section 8 of the chassis 2, and has the shaft of the final gear protruding outward as an output shaft. A front wheel a is provided on the output shaft 17,
The case 18 is formed so that the upper front side thereof is inclined to be as compact as possible, and the output shaft 17 is formed so as to be provided at a position offset to the front side of the case 18. Further, engagement recesses 20 are formed on both sides of the upper rear wall of the case 18, and an engagement protrusion 21 is formed on the lower end of the front wall to engage with the engagement groove 13 of the chassis 2. Further, the length from the output shaft 17 of the first spring unit 3 to the end on the engagement convex portion 21 side is L1, and this length is the length from the rear end surface of the chassis 2 to the rear vehicle bearing groove 10. approximately equal to.

Similarly, the second mainspring unit 4 has a mainspring and a reduction gear linked together in a case 18 of the same length as the one described above, and has the shaft of the final gear protruding outward as an output shaft. The case 18 is provided with a wheel b, but the upper rear side of the case 18 is inclined symmetrically with respect to the first spring unit 3, and there are engagement recesses 2 on both sides of the upper part of the front wall of the case 18.
0, an engagement convex portion 21 is formed at the lower end of the rear wall as an engagement groove that engages with the engagement groove 14 of the chassis 2. Furthermore, the length of the second spring unit 4 from the axle to the end on the engaging protrusion 21 side is L.
It is 2. This length is approximately equal to the length from the front end surface of the chassis 2 to the front axle bearing groove 9. Length L2 is greater than L1. This is because the space formed between the vehicle body 1 and the chassis 2 is narrower at the front where the first spring unit 3 is mounted than at the rear where the second spring unit 4 is mounted.

The second spring unit 4 may employ the same mechanism as the conventional main spring unit for driving the rear wheels;
Since the case 18 of the second mainspring unit 3 is symmetrically formed, there is only one more gear than the first mainspring unit 3.

Next, the non-driving wheel holder 5 has an engine shape, and has two axle holding grooves 22 and 23 formed therein.
The length to the end on the first side is formed corresponding to the lengths L1 and L2 of the first spring unit 3 and the second spring unit 4. The height H1 of the holder 5 is set equal to the height from the engagement protrusions 12, 12 of the storage section 8 of the vehicle chassis 2 to the bottom surface.

Next, when assembling a front-wheel drive type toy car using the above-mentioned components, the first spring unit 3 is placed in the front half of the storage section 8 of the chassis 2, and its engaging protrusion 21 is inserted into the front part of the chassis 2. It is installed by engaging the groove 13 and engaging the engaging concave portion 20 with the engaging protrusions 12, 12, and the engaging convex portion 21 of the non-driving wheel holder 5 is attached to the rear half of the storage portion 8. It is mounted by engaging the engagement protrusion 21 with the rear engagement groove 14 of the chassis 2 together with the wheel, and engaging the upper end with the engagement protrusions 12, 12. The vehicle chassis 2 in this state may be screwed together with the bumper members 6 and 7 to the vehicle body 1 by inserting screws through the screw holes 16.

When converting this to a rear wheel drive system, after disengaging the chassis 2 from the first spring unit 3 and the non-driving wheel holder 5 and removing them, the second spring unit 4 The engagement protrusion 21 and the engagement recess 20 are connected to the rear engagement groove 14 and the engagement protrusion 12,
12, and the engaging protrusion 21 and the upper end of the non-driven wheel holder 5 are engaged with the front engaging groove 13 of the chassis 2 and the engaging protrusions 12, 12. Bye. The non-driving wheel holder 5 can be selectively attached to the front or rear half of the storage section 8 by selecting either the front or rear wheel retaining grooves 22, 23.

Furthermore, when converting to a non-driving system, it can be achieved by engaging the non-driving wheel holders 5, 5 with the front and rear halves of the vehicle chassis 2.

Furthermore, when converting to a four-wheel drive toy car, the first spring unit 3 is inserted into the engagement groove 13 in the front half of the chassis 2 and the engagement protrusion 12 in the center.
The engagement protrusion 21 and the engagement recess 20 of the second mainspring unit 4 are inserted into the engagement groove 14 of the rear half of the chassis 2 and the engagement protrusion 12 of the central part. can be obtained by engaging and mounting them in the manner described above.

Effects of the invention As described above, according to the invention, it is possible to easily assemble and convert toy cars of any type, including front-wheel drive, rear-wheel drive, four-wheel drive, and non-drive, making it possible to make changes that were not possible before. You can enjoy a rich and interesting driving game.
