Description

[Detailed description of the invention] The present invention relates to a running body in a racing toy that is capable of racing on an endless track, and particularly to a running body that has a built-in spring drive mechanism, it is possible to wind up the mainspring from the outside. The present invention also relates to running in a racing toy configured such that the speed of the running body can be arbitrarily adjusted.

Conventionally, racing toy running bodies with a built-in spring drive mechanism that run along an endless track running path have been widely used. The method used was to remove the body and press the running body in one direction on the floor, for example, or to turn the crown protruding from the outside of the running body with one's fingers.

However, these methods of winding up the mainspring involve taking out the running body from the running path of the track, which is cumbersome and requires taking out the running body especially when the mainspring of the running body weakens during the race. The fun was cut in half.

Furthermore, in the case of racing toys, if each running object does not have the same speed conditions, the outcome of the race will be determined by the speed conditions prior to the racing technique.

However, since the constituent members of a traveling body generally differ in their finishing accuracy and assembly accuracy, it is difficult to obtain traveling bodies under the same conditions.

Therefore, a mechanism is required to equalize the speeds of the traveling bodies under such different conditions.

However, in the past, all speed adjustments were made at the final stage of the assembly process, so the adjustment work was extremely complicated, resulting in high costs.

The present invention was developed in order to eliminate the various drawbacks mentioned above, and it is possible to wind up the mainspring from the outside while the traveling body is running, and also to freely adjust the speed of the traveling body. The purpose of the present invention is to provide a running body for a racing toy.

The details of the present invention will be explained below with reference to the drawings.

Figure 1 explains the entirety of the present invention, and in the figure,
The lace toy, which is designated by the symbol 1 as a whole, is formed into an endless shape 8

The mainspring winding device 4 has a bottom plate 8 integrally provided with the track member 2 and protruding outward, and a cover 9.
At the top, there is provided a retractable mechanism as shown in enlarged form in FIGS. 6 and 7.

That is, a rotary shaft 12 is rotatably supported between support plates 10 and 11 protruding from the bottom plate 8.

The rotating shaft 12 is disposed perpendicular to the running path 3, and a cylindrical fitting portion 13 is integrally provided at its outer end (in FIG. 7, on the outside of the support plate 11). The portion 13 is formed with a square hole 13a into which a square shaft-shaped protrusion 14a of a cylindrical fitting portion fixed to one end of the flexible wire 7 is removably fitted.

A cylindrical clutch member 15 constituting one of the one-way clutches is fixed near the support plate 11 of the rotating shaft 12, and a clutch member 16 constituting the other one-way clutch is rotatably fitted opposite to this. are combined.

A relatively long pinion gear 17 is formed integrally with the clutch member 16.

A coil spring 19 is elastically mounted between the end face of the pinion gear 17 and a spring receiver 18 provided on the rotating shaft 12, and biases the clutch members 15 and 16 in the direction of engagement.

On the other hand, a drive shaft 20 is slidably and rotatably provided between the support plates 10 and 11 in parallel with the rotating shaft 12, and a groove shaft 21 is integrally fixed to the center of the drive shaft 20. .

Annular grooves 23 and 24 communicating with the spiral groove 22 are formed in the center of the groove shaft 21, and pins 25 projecting from the bottom plate 8 are fitted into these grooves 22-24.

A gear 26 is integrally provided on the grooved shaft 21, and this gear 26 is constantly meshed with the pinion gear 17.

Further, a coil spring 27 is provided between the groove shaft 21 and the support plate 11.
A coil spring 28 is loaded between the gear 26 and the support plate 10, and is biased inwardly.

Furthermore, one end of the drive shaft 20, in FIG.
A bracket 29 is integrally fixed on the outside of 0,
An L-shaped locking piece 30 is protruded from the lower part of the outer surface.
An engaging portion 31 made of a pinion gear and having an engaging portion is protruded above the locking piece 30 .

As is clear from FIG. 6, the above-mentioned bracket 29 is slidably fitted into a guide piece 32 having the same shape as the bracket 29 and projecting from the track member 2 side of the cover 9.

Therefore, at the start of running, the driver grasps the grip 5 and turns the manual operation handle 6, thereby rotating the rotary shaft 12 via the flexible wire 7, and rotating the two integrally with the clutch pieces 15 and 16 engaged.

Then, the gear 26 meshing with the pinion gear 17 is rotated, and the grooved shaft 21 is also rotated integrally from the position where the pin 25 is fitted into the annular groove 23 and advances to the position where it is fitted into the annular groove 24.

Therefore, the drive shaft 20 moves forward by bending the coil spring 28, and the retaining part 31 moves forward together with the bracket 29, and projects in the direction of the traveling path 3.

Therefore, the present invention relates to a running body used in a racing toy as described above, and the configuration thereof is shown in Figs. 2 and 3 below.
, FIG. 4, and FIG. 5 will be explained in detail.

In each of the above figures, the reference numeral 51 is the traveling object according to the present invention, which is illustrated as a motorcycle in this embodiment.

In this running body 51, 60 indicates left and right frames 60.
A and 60a are combined to form a body, and a front wheel 53 and a rear wheel 52, which is a driving wheel, are pivotally supported on this body 60.

A mainspring 61 is attached inside the body 60 by a mainspring winding shaft 55a, and the left and right frames 60
Spring winding shaft 55a protruding from a, 60b
A pair of spring winding gears 55 are provided protrudingly.

Furthermore, a gear 62 that is pivotally attached to the mainspring winding shaft 55 a is interlocked with a gear 64 provided on one side edge of the rear wheel 52 via a series of interlocking gears 63 .

It should be noted that the gear 6 of the gear train 63 that meshes with the gear 64
The shaft 65a of No. 5 is loosely fitted into the elongated hole.

Further, 66 is an intermediate frame.

Furthermore, guide rollers 54 are rotatably protruded from below both sides of the traveling body 51, respectively.

Therefore, this traveling body 51 has front wheels and rear wheels 52,
53 is fitted into the travel path 3, and the guide rollers 54 are brought into contact with both ends of the vehicle to balance the entire vehicle, so that the vehicle can run freely without falling over.

Further, as shown in FIG. 2, the traveling body 51 according to the present invention has an adjustment lever 56 rotatably protruding from the body above the rear wheel 52.

As shown in an enlarged view in FIG. 5, the adjustment lever 56 has its lower end firmly fitted into a support shaft 57 that projects horizontally into the body, so that it cannot be easily rotated without applying a large external force. installed on.

A torsion coil spring 58 is wound around the support shaft 57, one end of which is fixed to the adjustment lever 56 side, and the other end pressed against the support shaft 59 of the rear wheel 52.

Therefore, by rotating the adjustment lever 56, the pressure force of the torsion coil spring 58 against the support shaft 59 is adjusted,
The load on the rear wheels 52 can be adjusted.

This structure was adopted to adjust the running speed of each moving body because it was not uniform due to errors in the manufacturing process and finishing accuracy of parts. This is a feature of the idea.

Next, the operation of running a race using the running body 51 of the present invention will be explained. First, grip the grip 5 and turn the manual operation handle 6 to rotate the rotating shaft 12 via the flexible wire 7. Rotate them together with 15 and 16 in mesh.

Then, the gear 26 meshing with the pinion gear 17 is rotated, and the grooved shaft 21 is also rotated integrally from the position where the pin 25 is fitted into the annular groove 23 and advances to the position where it is fitted into the annular groove 24.

Therefore, the drive shaft 20 moves forward by bending the coil spring 28, and the retaining part 31 moves forward together with the bracket 29, and projects in the direction of the traveling path 3.

In this state, the rotating engagement member 55 consisting of the traveling body 51 and its gear faces the traveling path with the engaging portion 31 engaged,
As the manual operation handle 6 continues to rotate, the pin 25 continues to rotate while being fitted into the rear annular groove 24.
The engaging portion 31 also continues to rotate at the same position, and the mainspring of the traveling body 51 is wound up via the rotating engaging member 55.

When the manual operation handle 6 is rotated in the opposite direction when the winding is sufficiently performed, the groove shaft 21 is also rotated and moved back, and the annular groove 23 on the front side moves back to the position where the pin 25 is protruded.

Therefore, the bracket 29 and the retaining part 31 at the tip of the drive shaft 20 move backward, and the traveling body 51 is moved along the traveling path 3 by the released force of the mainspring stored in order to release the locking state with respect to the traveling body 51. and start driving.

In this way, the race is raced by completing a predetermined number of laps, but if the force of the mainspring becomes weak during the race, turn the manual operation handle 6 in the same way as described above to adjust the engagement part 31.
The moving body 51 is moved forward, the running body 51 is temporarily stopped, the mainspring is reeled in, and the running body 51 is caused to continue moving.

For example, in a 50-lap race, the winner will be determined by who arrives first.

As is clear from the above description, according to the present invention, a mainspring winding gear and an adjustment lever are provided protruding from a part of the body of the traveling body, and the mainspring winding gear consists of a mainspring and a series of gear trains. The mainspring drive mechanism is linked, and the adjustment lever is provided with a pressing means that can adjust the pressing force against the support shaft of the drive wheel of the traveling body in conjunction with the rotation of the adjustment lever. It is possible to freely select the load on the vehicle with a simple structure, and it is possible to adjust the speed with other vehicles to be raced to make it uniform. It has the great effect of allowing people to run races freely according to their will.
