Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a traveling toy with mysterious and fascinating movements.

(Prior Art) Traveling toys used as children's toys involve movement, so they are interesting as toys, and various toys have been proposed in the past. For example, there are various types such as those that run along a track, and those that travel in any direction and turn around when they hit a wall or the like and travel in the opposite direction. However, all of these running toys pursue only the fun of being able to run and move themselves, and the running motion is extremely simple and gets boring quickly.

Therefore, the present applicant has already proposed a running toy with mysterious movements, as shown in Japanese Utility Model Application Publication No. 14967/1983. This type of traveling toy has a shape that resembles a caterpillar, etc., and has a rotating drum rotatably supported by a support member of the toy, which is rotated using a drive source built into the drum. A mysterious running operation was performed by moving one shell member, one end of which was swingably attached to the support member, by a means linked to the rotation of the drum.

(Problem to be solved by the invention) However, since such traveling toys only have one shell member, which creates the toy's mysterious running motion, it is difficult to understand the movement process of the shell member. However, there was a problem in that children's curiosity about toys inevitably diminished. In addition, although the motion of the shell member expresses the biological motion of a caterpillar, etc., the motion itself feels like a mechanical motion (movement is stiff). There was a problem in that it was not possible to realistically and realistically express the softness of movement.

Therefore, the purpose of this invention is to be able to create movements that are very mysterious and fascinating when viewed, to arouse curiosity about toys, and to realistically and realistically express biological movements. Our goal is to provide a running toy that can

Next, based on FIG. 6 and FIG.
I will explain about it.

Reference numeral 17 denotes a motor driven by a battery (not shown). In the illustrated state, the output shaft 18 of the motor 17 is first driven through a gear 19, reduction gears 20, 21, clutch gear 22, and intermediate gear 23. It is transmitted to the shaft drive gear 24 and rotates in the forward rotation direction with respect to the drive shaft 7. At this time, the first worm gear 25 provided near the end of the drive shaft 7 rotates the flat gear 26 in the direction of arrow I, and the pinion gear 28 is integrally connected to the flat gear 26 via the shaft 27.
moves the reversing activation member 30 provided with the rack 29 that engages it in the direction of arrow K. An inclined surface 29a is formed at the end of this rack 29 and is inclined downward in the direction of arrow K. After the drive shaft 7 continues to rotate normally for a while, this eventually comes into contact with the side of the outer end 31a of the lever member 31. This is pushed upward along the slope 29a. Then this lever member 31
The needle-like locking portion 31b provided at the inner end of the clutch is engaged with the groove of the second worm gear 32, and the clutch shaft 33 equipped with the second worm gear 32 is moved in the direction of arrow M against the repulsive force of the spring 34. , after that, it comes off from the groove of the second worm gear 32 and engages with the end face of the second worm gear 32 to prevent the shaft 33 from returning due to the spring 34 . At this time, the clutch gear 22 at the tip of the clutch shaft 33 separates from the intermediate gear 23 and comes into direct meshing with the large diameter gear 24a formed at the tip of the gear 24. Therefore, at this point, the number of gears that transmit the drive of the motor 17 to the drive shaft 7 is reduced by one, and the drive shaft 7 begins to rotate in the opposite direction. Along with this, the first worm gear 25, the flat plate gear 2
6. The pinion gear 28 is reversed and the rack gear 2
9, that is, the moving direction of the reversal activation member 30 is changed from the direction of arrow K to the direction of arrow L. This reversal starting member 30
An engaging part 30a is provided at the tip of the lever, and when the reversal activation member 30 moves in the direction of arrow L, this engaging part 30a eventually comes into contact with the outer end 31a of the lever, pushing the side part of the lever downward. At the same time, the locking portion 31b is removed from the end surface of the second worm gear 32 in the radial direction, the clutch shaft 33 returns to its original position due to the repulsive force of the spring 34, and the drive shaft 7 is returned to its original position in the same direction. Rotate. In this way, this drive unit 16 has a reversing mechanism equipped with gear changing means, and reverses the rotational direction of the drive shaft 7 at regular intervals. The drive unit 16 is mounted such that its center of gravity is offset from the center of the rotating drum by a predetermined distance.

Traveling toy 1 with the mechanism of this embodiment explained above
Explain the overall operation of.

First, the rotating drum 2 is rotated in the forward direction by the forward rotation of the drive shaft 7 of the drive unit 16 described above, so that the traveling toy 1 rotates and travels in the direction of arrow A in FIG. At this time, since the center of gravity of the rotating drum 2 is displaced from its center, the rotational speed of the rotating drum 2 periodically slows down and speeds up repeatedly as if beating. For this reason, the running toy 1 moves like a living creature such as an insect moving forward.

When the rotation direction of the drive shaft 7 is reversed by the reversing mechanism of the drive unit 16, the direction of the rotary drum 2 is reversed, and the traveling toy 1 is rotated backward in the direction of arrow B in FIG. At this time, the tip of the stopper member 4g of the first shell member 4a of the plurality of shell members 4 comes into contact with the running surface to restrict backward rotation of the running toy 1 and stabilize the toy 1. The protrusion 4h of the engagement piece 4f of the first shell member 4a comes into contact with the running surface and comes off from the fitting hole 4e of the one first shell member 4a, thereby engaging the pair of first shell members 4a. At the same time, the pair of gear members 5a, which is the means 5 for swinging the pair of first shell members 4a, mesh with the large and medium diameter gears 12 and 13 of the rotating drum 2, and move in the direction of arrow D in FIG. By gradually moving the two pairs of second shell members 4b in the radial direction via the movement mechanism 6 provided in the pair of first shell members 4a and the two pairs of second shell members 4b. Swings (opens) smoothly and gradually. As for the movement of the pair of first shell members 4a and the two pairs of second shell members 4b, since each member is independent, the swinging speed of each member changes slightly. Therefore, the plurality of shell members 4 of the traveling toy 1 can realistically and realistically represent movements similar to the movement of the legs of an animal such as an octopus.

Next, from the state shown in FIGS. 2 and 3 in which the plurality of shell members 4 are oscillated, the traveling toy 1 moves to the second position as the wavy projections 2b of the drum 2 come into contact with the running surface due to the reversal movement of the rotating drum 2. Travel in the direction of arrow A in the figure.

Then, when the drive unit 16 is reversed again, the rotating drum 2 is also reversed, and the traveling toy 1 returns to the state shown in FIG. 1 through the states shown in FIGS. 2 and 3 again.
Change the direction of travel in the state shown in the figure.

As described above, although the traveling toy 1 of the present invention is a toy, its motions are mysterious and fascinating, and it can realistically and realistically express soft biological motions, so it can be used by children and others. can arouse great curiosity.

In this embodiment, the reversal of the driving direction was made to occur at regular intervals by the combination of gears.
For example, the lever 31 may be switched when the rudder 3b or the like touches an obstacle or the like.

(Effects of the invention) As is clear from the above explanation, according to the invention,
It is possible to create movements that are very mysterious and fascinating when viewed, arouse curiosity about the toy, and have effects such as being able to realistically and realistically express biological movements.
