Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a mounting structure for a drive mechanism in a traveling toy, in which drive units each having a drive mechanism are accommodated in a recess provided in a chassis of the toy in succession.

(Prior Art) Generally, it has been proposed and implemented that a driving mechanism is housed in this type of traveling toy and the driving force is used to drive the toy, but conventional traveling toys house only one such driving mechanism. As a result, the game lacks running speed, power, climbing ability, etc., and the fun of play is halved, so a solution to this problem has been desired.

(Problems to be solved by the invention) The present invention has been made in view of the above-mentioned viewpoints, and in particular, it is possible to easily and reliably attach the drive unit to the chassis with a simple structure. The object of the present invention is to propose a mounting structure for a drive unit in a traveling toy, which can provide a traveling toy with excellent running speed, power, and hill-climbing ability.

(Means for Solving the Problems) As a means for solving the above problems, the mounting structure of the drive unit in the traveling toy according to the present invention is characterized by having the following requirements.

(a) A recess is formed in the chassis of the traveling toy to house a drive unit having a plurality of drive mechanisms in the front and back direction, and an engaging part is provided at the front and rear of the recess, and a locking pawl is provided on the side wall.

(b) Engagement convex portions are formed protruding from the front and rear ends of the drive unit at positions overlapping with each other, and the drive unit is housed in a recess formed in the vehicle chassis in the front-rear direction.

(c) Within the vehicle chassis recess, the front and rear engaging protrusions of the frontmost and rearmost drive units are respectively engaged with the front and rear engaging parts of the recess.

(d) In the chassis recess, the rear engagement protrusion of the front drive unit overlaps the front engagement protrusion of the rear drive unit, and the front engagement protrusion of the upper engagement protrusion or the drive unit having the same overlaps with the front engagement protrusion of the rear drive unit. must be locked to the locking claw on the side wall of the recess.

(Operations and Effects of the Invention) As described above, according to the present invention, a recess for accommodating the drive unit is formed in the chassis of the traveling toy,
An engaging portion is provided at the front and rear of the recess, and locking pawls are provided on both side walls, and engaging convex portions are formed at the front and rear of the drive unit that is housed in the recessed portion one after the other in the vertical direction. First, the drive units are housed in the recessed portion of the chassis in a row. At this time, the front and rear engaging convex portions of the frontmost and rearmost drive units are respectively engaged with the front and rear engaging portions of the recessed portions. Next, at the connecting portion of the front and rear drive units, overlap the rear engaging convex portion of the front drive unit and the front engaging convex portion of the rear drive unit, and connect the upper engaging convex portion or the drive unit having the same. The front part of the recess is locked to the locking claw on the side wall of the recess. Thereby, the drive unit can be easily and securely attached without using fixing means such as screws. By connecting drive units in this way, the driving force is greatly increased, making it possible to obtain a running toy with excellent running speed, power, and hill-climbing ability.It also enables unusual running, and expands the range of play. can be expanded.

(Example) Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.

In the figure, reference numeral A indicates the mounting structure of the drive unit in the traveling toy according to the present invention. This drive unit mounting structure A is composed of a chassis 1 of a traveling toy and drive units a and a' accommodated in this chassis 1.

The chassis 1 has a recess 2 on its upper surface to accommodate the drive units a and a', and an engaging section 5 at the upper end inside the front wall 3 and the lower inside inside the rear wall 4 of the front and rear walls 3 and 4 in the longitudinal direction. , 6 are integrally provided in a protruding manner. Further, side walls 7, 7 in the longitudinal direction of this recess 2
Locking pieces 8, 8 are provided at opposing positions in the center of the locking pieces 8, and locking claws 9, 9 are protruded from inside the tips of the locking pieces 8, 8. 10,10,
Reference numerals 10 and 10 indicate shaft fitting grooves formed in the side walls 7, 7.

The drive units a and a', which are housed one after the other in the recess 2 formed on the upper surface of the vehicle chassis 1, have the same shape and the same function, and the drive units a and a' are located at approximately the center of the front and back and at the lower end of the rear. Engagement convex portions 11, 11a, 12, and 12a are provided protrudingly, respectively. These engaging protrusions 11 and 12 and 11a and 12
a are provided at height positions where they overlap with each other, and the distance between the front engaging protrusions 11, 11a and the lower surfaces of the units a, a' is approximately equal to the thickness of the rear engaging protrusions 12 and 12a. . Further, the drive unit a,
a' is the driving force of the drive source such as a mainspring, motor, friction, etc., which is transmitted through multiple gears to the wheels 13, 13,
The driving mechanism that is transmitted to the shafts 14, 14a of the shafts 13a, 13a is made into a unit. The mainspring is wound up by the wheels 13, 13, 13a, 13a, and the driving force is directly transmitted to the driving wheels to cause the traveling toy to travel.

Since the mounting structure of the drive unit in the traveling toy is constructed as described above, in order to accommodate the drive units a and a' in the recess 2 formed on the upper surface of the chassis 1, first, as shown in FIG. As shown in FIG. 1, a drive unit a is accommodated in the front part of a recess 2 formed in this vehicle chassis 1, and a front engaging protrusion 11 thereof is arranged in an engaging part 5 formed at the upper end of the front wall 3 of the recess 2. Engage the bottom. Next, drive units a' are accommodated in the recess 2 at the rear of drive unit a one after the other. In this case, the engaging protrusion 12a protruding from the lower surface of the rear end of this drive unit a' is engaged with the lower part of the engaging part 6 protruding from the inner lower part of the rear wall 4 of the recess 2, and Engagement protrusion 11a protruding from the center
overlaps the engagement convex portion 12 protruding from the rear lower end of the drive unit a. Locking claws 9, 9 are provided on the upper sides of both sides of the overlapped connecting portion 15 and protrude inside the tips of the locking claws 8, 8, which are provided at opposing positions in the center of the side walls 7, 7 of the recess 2. Lock by. As a result, the recess 2 formed in the chassis 1
The drive units a and a' can be easily and reliably housed in the drive unit without using fixing means such as screws. Note that the locking pawl 9 does not necessarily need to be locked to the upper engaging protrusion. For example, it may be configured to press the front part of the drive unit that has the upper engaging protrusion.

As mentioned above, by accommodating the two drive units a and a' in the chassis 1, a running toy with excellent running speed, power, and hill-climbing ability can be obtained. You can enjoy interesting games.

In the above embodiment, two drive units a and a' are housed in the recess 2 formed in the chassis 1, but the present invention is not limited to this, and for example, three or more drive units may be housed. In this case, the chassis 1 will of course be formed to accommodate this, and
The same applies to the locking claws 8, 8 provided at opposing positions on the side walls 7, 7 of this recess 2.
