A first drive mechanism in which a moving body in the form of a car is attached and a driving force is stored in a mainspring when the moving body is pulled out backward from the main body of the vehicle; A second drive mechanism is provided with a flywheel that rotates at high speed to which driving force is transmitted from the first drive mechanism by a gear train when the vehicle is pulled toward the traveling vehicle body, and the first and second drive mechanisms A switching mechanism in which a switching gear is attached to a gear shaft that is slidable in the axial direction is disposed between the mechanism and the drive axle to which the drive wheel is attached, and the switching mechanism has a switching gear mounted on a gear shaft that can slide in the axial direction. When the mainspring unwinds, the movable body on the floor is attracted to the vehicle body, and at the same time, the flywheel of the second drive mechanism is rotated at high speed to accumulate driving force, and the movable body is mounted on the vehicle body. Then, the gear shaft of the switching mechanism is moved by engaging with a desired operating mechanism such as a rotating plate that rotates when the movable body comes into contact with it and an operating rod that slides in conjunction with the rotating movement. The connection between the first drive mechanism and the second drive mechanism is severed, and
The traveling vehicle is a driving device for a traveling toy configured so that a moving object is placed on a loading platform and the vehicle is driven by the driving force of the second driving mechanism.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 and subsequent figures show an embodiment of a traveling toy equipped with the drive device of the present invention. Figure 1A is an overall perspective view of a traveling vehicle, and Figure 1B is a motorcycle-shaped moving body pulled out from the traveling vehicle. Fig. 2A is a perspective view showing the state in which the driving force is stored in the first drive mechanism; Fig. 2A is a perspective view showing the state in which the upper outer shell of the vehicle body is removed; Fig. 2B is a perspective view showing the operating mechanism at the rear of the chassis. FIG. 3 is an exploded perspective view of the drive device of the present invention.

In the figure, reference numeral 1 denotes the vehicle body, and a loading platform 2 is provided at the rear of the chassis. Bearing plates 8, 8 protrude from the rear of the loading platform 2, and bearing plates 8, 8 are attached to the rear wall of the loading platform 2. The pin shafts 7a and 7b of the load receiving plate 6 are supported, and the load receiving plate 6 has a structure that can be opened and closed using the pin shafts 7a and 7b as fulcrums. A mooring frame 4 is erected in the center of the chassis, and a machine frame 1 of a drive mechanism, which will be described later, is located in front of the mooring frame 4.
3 is rotatably provided with a rotary plate 19 that pivotally supports support shafts 19a and 18b, and a long hole 21 formed in the lower side surface of the rotary plate 19 has a protruding portion formed at the base end of the connecting rod 10. A pin 9a protruding from the side surface of a protruding piece 9 provided at the inner corner of the cargo receiving plate 6 is fitted into the shaft hole 10a drilled at the tip of the connecting rod 10, into which the pin 10b is fitted; The rotating plate 19 and the load receiving plate 6 are connected.

The movable body 3 is normally mounted on the loading platform 2 of the vehicle main body 1 as shown in FIG. A through hole 20 opened in the center of the moving plate 19
It is attached to the end of the string 5 that passes through the inside.
Therefore, when the movable body 3 is pulled out to the rear of the vehicle body 1, the rotary plate 19 is pulled rearward by the string 5 inserted into the through hole 20, and rotates rearward about the support shafts 19a and 19b. The connecting rod 10 moves in conjunction with this.
moves rearward, so the load receiving plate 6 is opened and becomes the state shown in FIG. In addition, as the mainspring of the first drive mechanism unwinds, the moving body 3 is drawn to the traveling vehicle body 1, rides on the loading platform, and stops while being fitted into the mooring frame 4. At this time, the moving body 3 The front end presses the rear part of the rotating plate 19, and the rotating plate 19
Since the lower end of the container pivots forward, the load receiving plate 6 connected by the connecting rod 10 pivots around the pin shafts 7a and 7b and is closed, resulting in the state shown in FIG. 1A. Note that the shape of the moving body 3 is not particularly limited, but since the main body 1 is a running vehicle, the shape of the moving body with running wheels like that of a motorcycle eliminates unnaturalness and is a desirable combination. Become.

Next, the driving device of the traveling body in the present invention is the second
As shown in FIG. A, the drive device is assembled and attached to the machine frame 13 on the chassis in front of the mooring frame 4, and the details of the drive device shown in FIG. 3 will be described below.

First, the first drive mechanism 12 consists of a mainspring 16 and a string 5.
It consists of a winch 17 wrapped with. The mainspring 16 is attached at its inner end to the mainspring shaft 15, and at its outer end to a suitable position on the machine frame 13 (not shown).

In addition, a winch 17 attached to the mainspring shaft 15
The base end of the string 5 is locked and wound around the flange, and a gear 18 is formed by cutting teeth into the peripheral surface of the flange on one side. A movable body 3 is attached to the end of the string 5, and when the movable body 3 is pulled out to the rear of the vehicle body 1, the mainspring shaft 15 rotates and the mainspring 16 is tightened and driven by the first drive mechanism. Power will be stored.

The second drive mechanism 11 is built into the machine frame 13 and includes a flywheel 48 that is rotatably attached to a shaft 47;
It consists of a gear train formed by a plurality of gears that transmits driving force to the flywheel 48.
That is, a gear 40 having a small diameter and long in the axial direction and a gear 41 having a large diameter are mounted on the shaft 42, and a gear 43 having a small diameter and a gear 41 having a large diameter that mesh with the gear 41 are mounted on the shaft 45. The large-diameter gear 44 meshes with a gear 46 that is pivoted on a shaft 47 of a flywheel 48.

Next, a transmission mechanism that transmits the driving force from the first drive mechanism 12 to the switching mechanism 14 or the drive axle 30 will be described.

A gear 18 attached to the winch 17 meshes with a gear 32 that transmits drive to a switching mechanism 14, which will be described later. The gear 32 and the gear 33 are rotatably attached to a shaft 34, and both ends of the shaft 34 are rotatably supported in arcuate grooves 35, 35 formed in the machine frame 13. Therefore, when the movable body 3 is pulled out to the rear of the vehicle body 1, the gear 18 of the winch 17 rotates in the clockwise direction shown in the third figure, so that the shaft 34 on which the gears 32 and 33 are mounted rotates in the arcuate groove 35, 35 and is separated from the switching mechanism 14 or the gear on the drive axle 30 side and does not mesh with it.

Conversely, when the mainspring 16 of the first drive mechanism 12 is unrotated and the moving body 3 is being drawn toward the traveling vehicle body 1, the gear 18 attached to the winch 17
rotates in the counterclockwise direction shown in the third figure, so the shaft 34
is pressed below the arcuate grooves 35, 35, so the gear 33 meshes with the switching mechanism 14 or the gear on the drive axle 30 side, so that driving force can be transmitted.

Next, from the first drive mechanism 12 to the second drive mechanism 11
The switching mechanism 14 that transmits the driving force to the drive axle 30 side and further switches the driving force to the drive axle 30 side will be explained.

The switching mechanism 14 has switching gears 39 and 37 pivoted,
It is composed of a gear shaft 38 that is slidable in the axial direction. A coil spring 5 is attached to one end of the gear shaft 38.
0 is wrapped around the gear shaft 38 to press the gear shaft 38 toward the operating rod 22. A cylindrical contactor 49 is pivotally attached to the other end of the gear shaft 38, and the gear shaft 38 is connected to the gear shaft 38 by engaging with the engagement slope 23 formed at the tip of the operating rod 22. It slides in the axial direction.

The operating mechanism for operating the switching mechanism 14 includes a rotating plate 19 rotatably supported on the machine frame 13 and an L-shaped operating rod 22. Operating rod 22
A coil spring 22a is tensioned on and pulls the operating rod 22 toward the rotating plate 19.

Furthermore, the bent portion 22' of the operating rod 22 is connected to the rotating plate 1.
It is in contact with the lower end surface 19c of 9. Therefore, when the movable body 3 gets on the loading platform 2 and the front part of the movable body 3 rotates the rotating plate 19 forward by disengaging the mainspring 16 in the first drive mechanism 12, the operating rod 22
slides forward and an engagement slope 23 formed at the tip.
is in contact with the contact 49.

The purpose of this operating mechanism is to move the gear shaft 38 of the switching mechanism 14 in the axial direction, and this can be done by any method such as rotating a rotating lever instead of the operating rod 22. It is.

Next, a driving wheel mechanism including driving wheels 36, 36 to which driving force is transmitted from the first driving mechanism 12 or the second driving mechanism 11 via the switching mechanism 14 to drive the vehicle will be described.

Drive wheels 36 , 36 are pivotally attached to both ends of drive axle 30 . A pair of gears 31 and 51 are rotatably fitted loosely into an intermediate portion of the drive axle 30. Clutch pieces 53b, 54b on one side of slip-type clutch members 53, 54, which are safety devices, are integrally provided on the outer surfaces of the gears 31, 51.
It is loosely fitted so that it can rotate freely. Further, a pair of clutch pieces 53a and 54a that engage with the clutch pieces 53b and 54b are pivotally attached to the drive axle 30, and the clutch pieces 53a and 53b and the clutch pieces 54a and 54b are attached to the inside of the gears 34 and 51. The engagement state is maintained by being pressed by a push spring 55 wound around the drive axle 30.

Although the drive mechanism of the present invention is constructed as described above, two transmission methods can be selected for implementation.

One method is shown by the solid line in Figure 3,
Gear 18 → Gear 32, Gear 33 → Gear 34 → Switching gear 37, Switching gear 39 → Second drive mechanism (Gear 4
0), the mainspring 16 of the first drive mechanism 12 moves the traveling vehicle body 1 forward at a gentle speed when the vehicle is released, and the moving body 3 rides on the loading platform 2 to operate the switching mechanism 14. and the traveling vehicle body 1 is the second
The vehicle is driven at high speed by the driving force of the drive mechanism 11.

The second transmission method is to transfer the gear 32 directly to the switching mechanism 14.
The vehicle main body 1 is stopped when the first drive mechanism 12 is unrotated, and the moving body 3 is mounted on the loading platform 2 to operate the switching mechanism 14. By doing so, the vehicle starts traveling by the driving force of the second drive mechanism 11.

Note that when the slip-type clutch 53 transmits the driving force using the first transmission method, when a sudden forward force is applied from the outside to the vehicle body 1 that is running slowly, the clutch pieces 53a, 53b
The mechanism slips and rotates to prevent excessive loads from being applied to other mechanisms.

Further, when the vehicle body 1 is traveling at high speed due to the driving force of the second drive mechanism 11, the clutch 54 is activated when the vehicle body 1 is prevented from moving forward by an obstacle or the like. 54b slips and rotates to prevent excessive loads from being applied to other mechanisms.

Next, the operating state of each mechanism constituting the drive device of the present invention will be explained.

First, it is assumed that FIG. 1A shows a state in which the moving body 3 is placed on the loading platform 2 of the vehicle body 1 and the vehicle body 1 is also stopped. From this stopped state, Figure 1B
When the movable body 3 is pulled out to the rear of the vehicle body 1 as shown in FIG.
The load receiving plate 6 connected by the connecting rod 10 opens rearward, and the operating rod 22 is moved backward by the coil spring 22a. At this time,
Since the gear shaft 38 of the switching mechanism 14 is disengaged between the contact 49 provided at the shaft end and the engagement slope 23 at the tip of the operating rod 22, the gear shaft 38 is moved toward the operating rod 22 by the coil spring 50 and pressed. It is being The switching gear 37 is in mesh with the gear 31 or the gear 33 of the drive axle 30, and is in mesh with the other switching gear 3.
9 does not mesh with the gear 51 of the drive axle 30, but meshes with the gear 40 of the second drive mechanism 11, so that the first drive mechanism 1
2 is in a state where it is possible to transmit the driving force stored in it.

Next, as shown in FIG. 1B, when the movable body 3 that has been pulled out is placed on the floor, the movable body 3
The string 5 is wound up by the unwinding of the mainspring 6 of No. 2 and is drawn toward the vehicle main body 1 side. At this time, driving force is transmitted from the first driving mechanism 12 to the flywheel 48 of the second driving mechanism 11 by a gear train including switching gears 37 and 39, and the flywheel 48 rotates at high speed, thereby storing driving force.

Eventually, the moving body 3 rides on the cargo receiving plate 2 using the opened cargo receiving plate 6 as a step, and fits into the mooring frame 4 provided in the center of the chassis, and the front end of the moving body 3 presses the rear of the rotating plate 19. Rotate the rotating plate 19 forward. By rotating the rotating plate 19 forward, the load receiving plate 6 connected by the connecting rod 10 is closed, and the operating rod 22 slides forward, and the engagement slope 23 at the tip contacts the contact 49 to switch. The gear shaft 38 of the mechanism 14 is slid in the axial direction.
Therefore, the switching gear 37 is either gear 31 or gear 3.
The other switching gear 39 meshes with the gear 51 provided on the drive axle 30, and the driving force of the second drive mechanism 11 is transmitted from the gear 40 of the second drive mechanism 11 to the drive axle 30. Therefore, the vehicle body 1 starts traveling forward at high speed.

In this way, a traveling vehicle implementing the drive device of the present invention stores driving force in the first drive mechanism equipped with a mainspring by pulling out the movable body, and when the first drive mechanism is disengaged, the drive force is stored in the second drive mechanism equipped with a flywheel. Drive force is stored in the drive mechanism, and when a moving object pulled by a string gets on the platform of the main body, the drive power transmission mechanism is switched, and the vehicle main body runs with the drive force of the second drive mechanism. Furthermore, it is possible to provide a driving device for a traveling toy that has excellent features such as being able to be used as a normal friction-type traveling toy when the moving object is on the carrier of the main body. .
