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 Utility Model Application 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 rotating 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, since one end of the shell member is simply swingably attached to the support member, the mechanical chain reaction when the shell member is interlocked by the above-mentioned means is slow, and therefore the shell member The drawback was that it was difficult to realistically and realistically express biological movements (smoothness of movement).

Therefore, the purpose of this invention is to be able to smoothly create movements that are very mysterious and fascinating to watch, with a simple structure, and to arouse curiosity about toys, as well as to create a movement that is very mysterious and fascinating when viewed. To provide a running toy that can realistically and realistically express motion.

(Means for Solving the Problems) The present invention for achieving the above object includes a rotating drum 2 which is rotated in forward and reverse directions by a drive source 17 of a drive unit 16 housed inside, and an outer periphery on both sides of the rotating drum 2. In the traveling toy 1, the shell member 4 is provided with a support member 3 that rotatably supports the shell member 3 via a gear, and a shell member 4 whose one end is swingably attached to the support member 3. The lower half of the member 3 is radially divided into a plurality of first shell members 4a and a second shell member 4b that moves in conjunction with the movement of the first shell members 4a.
The first shell member 4a is attached to the shell member 4a on the rotating drum 2.
A spring 35 is provided on the support member to induce the movement of the means 5 and to spring the movement of the first shell member 4a.

Guide members 14 each having a substantially hook-like shape in a plan view, the other end of which is attached to the surface of the pair of first shell members 4a and extends from the side base end of the surface of the first shell members 4a, and a guide member 14 that is symmetrical to each guide member 14. A substantially boomerang-shaped member in a plan view is provided with one end fixed to the side proximal end of the back surface of each of the second shell members 4b and the other end extending to the side proximal end of the back surface of each of the first shell members 4a. It is composed of members 15 forming the following. This movement mechanism 6 is operated by the guide member 14 and member 15 of the mechanism 6.
By pinching the base end of the side part of the shell member 4a,
Each of the second shell members 4b described above is caused to smoothly swing in the radial direction (see arrow C in FIG. 3) in conjunction with the swing of each of the first shell members 4a (see arrow B in FIG. 3). I can do it.

As a result, the plurality of shell members 4 described above can create a very mysterious and fascinating movement when viewed, and can arouse the curiosity of children and the like.

Here, the spring 35 described above will be specifically explained with reference to FIG. 4 and FIGS. 6 and 7.

The springs 35 are a pair of torsion springs 35 respectively provided on the inner wall of the tip end of the support member 3 located in the radial direction of the rotating drum 2, as shown in FIG.
The pair of torsion springs 35 are connected to a pair of holding members 35a which are U-shaped in plan view and are fixed to the inner wall of the tip end of the support member 3 via bolts 35b.
It is fitted and held by protrusions 35c protruding from each inner wall. Moreover, this pair of springs 35 are

The moving toy 1 can be caused to swing smoothly, and the biological motion of the traveling toy 1 can be expressed realistically and realistically.

Next, based on FIG. 8 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 with it in the direction of arrow K. An inclined surface 29a that is inclined downward in the direction of arrow K is formed at the end of this rack 29, and after the drive shaft 7 continues to rotate in the normal direction for a while, this eventually causes the outside of the lever member 31 supported on the side wall of the rotating drum 2. It comes into contact with the side of the end 31a and pushes it upward along the slope 29a. Then, the needle-like locking part 3 provided at this inner end
1b is engaged with the groove of the second worm gear 32, moves the clutch shaft 33 equipped with the second worm gear 32 in the direction of arrow M against the repulsive force of the spring 34, and then disengages from the groove of the second worm gear 32 and moves therefrom. It locks with the end face to prevent the shaft 33 from returning due to the spring 34. At this time, the clutch shaft 33
The clutch gear 22 at the tip is separated from the intermediate gear 23, and the large diameter gear 24 formed at the tip of the gear 24 is separated from the intermediate gear 23.
It comes to mesh directly with a. 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 gear 26 and the pinion gear 28 are reversely rotated, and the moving direction of the rack gear 29, that is, the reversal activation member 30 is changed from the direction of arrow K to the direction of arrow L. An engaging portion 30a is provided at the tip of the reversing activation member 30, and as the reversing activation member 30 moves in the direction of arrow L, the engaging portion 30a eventually engages with the outer end 31 of the lever.
a and pushes the side part of this downward, and at the same time, the locking part 31b comes off in the radial direction from the end surface of the second worm gear 32, and the clutch shaft 33 returns to its original position again by the repulsive force of the spring 34. The drive shaft 7 rotates forward again in the same direction as in the initial state.
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.

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 direction of rotation of the drive shaft 7 is reversed by the reversing mechanism of the drive unit 16, the direction of the rotating drum 2 is reversed, causing the traveling toy 1 to rotate 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 contacts the running surface to restrict backward rotation of the toy 1.
and the protrusion 4h of the engagement piece 4f of the other 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, so that the pair of first shell members 4a At the same time as the engagement between the shell members 4a is released, 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. By gradually moving in the direction of arrow D in FIG. 3, the pair of first shell members 4a gradually swing, and
This rocking can be induced by a pair of springs 35 provided on the support member 3 and can be smoothly performed, and the two pairs of second shell members 4b accompanying this smooth rocking can be moved by the movement mechanism. 6, it can be smoothly and gradually swung (opened) in the radial direction. The movement of the pair of first shell members 4a and the two pairs of second shell members 4b is such that the swing speed of each member changes slightly because each member is independent. 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.

In this way, the running toy 1 of the present invention can smoothly create mysterious and fascinating movements in its movements, even though it is a toy 1, with a simple configuration. In addition to being able to express realistically,
This can make the child more curious about the toy 1, and the user can have fun playing with it.

(Effects of the invention) As is clear from the above explanation, according to the invention,
It is possible to smoothly create movements that are very mysterious and fascinating to watch with a simple composition, arousing curiosity about the toy, and realistically and realistically expressing the biological movements of the toy. It has the following effects.
