Description

[Detailed Description of the Invention] (Field of the Invention) The present invention relates to a multi-legged toy that walks on its own using a power source such as a spring.

(Prior Art) Toys modeled after animals such as dogs that walk on four legs have been widely used. This is 2 on each left and right
A pair of book legs move back and forth alternately, and the main body swings from side to side as it walks, but if this swing becomes too large, it will fall, so the remaining two legs, which do not contribute to forward movement, are placed in order to prevent it from falling. Make sure that at least one of the legs is on the walking surface to support the main body.
I had to drag my feet along. As a result, walking ability was hindered, the stride width became narrower, and walking speed tended to slow down. Therefore, it was very boring for children and others to watch, lacked interest and fun, and was extremely boring.

In addition, there was a fatal defect in that the robot could not deviate from its unstable gait and could not walk, for example, on a walking surface slightly inclined to the left or right.

(Purpose of the invention) The invention was made to solve the above drawbacks.
The purpose of this is to model multi-legged creatures such as octopuses and science fiction space animals, so that their appearance does not look unnatural, and their ability to walk is not hindered at all. To provide a multi-legged walking toy that is fast, can walk anywhere, and can be played with great interest by children.

(Structure of the invention) In order to achieve the above object, the invention consists of a main body with a built-in power source, a main body located at the bottom of the main body near the center in the left and right direction, and two sets of left and right legs centered around a fulcrum attached to the main body. a walking leg that alternately reciprocates or moves in an elliptical manner in addition to the reciprocating motion, and walks with the main body tilting to the left and right; It is characterized by having a pair of left and right support legs that have the same shape and short length and provide support when the main body is tilted.

(Embodiment) A preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

Figure 2 is a side view of the same side, Figure 3 is an exploded perspective view showing the internal structure, Figures 4 A to D are explanatory diagrams of the operation of the front legs for walking, showing the internal side, and Figures 5 A to D are the rear legs for walking. It is an explanatory diagram of the movement of the foot.

First, with reference to FIGS. 1 and 2, the overall external configuration of the multi-legged walking toy according to the present invention will be described.

The embodiment is modeled after a space animal character in science fiction, and the multi-legged walking toy designated by reference numeral 1 consists of a head 2 and six legs 3.

The head 2 consists of a spherical case 4 and a driving section 5 (see FIG. 3) housed inside, and the case 4 has openings 6 and 7 shaped like eyes and a mouth formed in the front surface thereof.
A face panel 9 (see FIG. 3) depicting eyes and a mouth is provided inside so that it can be seen from the outside.

On the other hand, the foot portion 3 includes two walking feet 3a, 3b, 3c, and 3d located near the center in the left-right direction, and a pair of left and right supporting feet 3e, 3f on both outer sides of these feet.
are attached to the left and right side surfaces of the drive section 5 built into the case 4, as described later. Each of these legs 3a
-3f are all formed in substantially the same shape, and consist of a round bar-shaped leg portion 3h having a spherical node 3g in the middle and a hemispherical foot portion 3i. In addition, supporting feet 3e, 3f
are formed shorter than the walking legs 3a, 3b, . . . so that they are higher than the walking surface E by a height _H1 . Reference numeral 11 is a knob for winding the mainspring which is the power source.

Next, the internal structure will be specifically explained with reference to FIG. The drive unit 5 includes a substantially rectangular parallelepiped drive case 21 containing a power source such as a mainspring, and has a front foot support portion 22 and a rear foot support portion 23 formed in the front and rear portions of the drive case 21 .

On the other hand, a drive shaft 24 that protrudes laterally and is rotatably driven by the power source is provided at a position near the rear of the side of the drive case 21, and the center of the disc 27a of the cam-shaped drive member 26 is fixed to the drive shaft 24. At the same time, an eccentric pin 27b is provided protruding from the outer side of the end surface of the disc 27a. This pin 27b has a hole 2 in the front leg drive member 28.
9. Furthermore, loosely fit into the holes 32 of the hind leg drive member 31, and attach the retaining member 47.

Incidentally, the upper part of the walking forefoot 3a is integrally provided with a flat plate 35 having a hole 36 and a pin 34 provided above the forefoot, and a support pin 45 protruding from the forefoot support part 22 is loosely fitted into this hole 36, and a retaining member 47 is fitted. Install. Further, the pin 34 is loosely fitted into a hole 30 formed in the front part of the front leg drive member 28.

On the other hand, the upper part of the walking hind leg 3b is integrally equipped with a flat plate 38 having a long hole-shaped guide groove 39 and a pin 37 provided below the guide groove 39, and a support protruding from the hind leg support part 23 is provided in the guide groove 39. Loosely fit the pin 46,
Attach the retaining member 41. At the same time, the pin 37 is formed in a hole 33 at the rear of the rear foot drive member 31.
fit loosely into A guide groove 48 is provided in the front part of the rear leg drive member 31 and is cut backward from the front end, and this groove 48 is engaged with the mainspring winding shaft 19 exposed toward the front of the left and right sides of the drive case 21. One of the shafts 19 extends to the outside of the spherical case 4, and the knob 11 is attached thereto.

On the other hand, a mounting protrusion 4 is provided at the upper end of the supporting foot 3e.
4 is inserted into the mounting hole 43 provided at the lower center of the drive case 21 and fixed.

By the way, there is a face panel 9 above the case 21.
The mounting base 8 includes a horizontal support part 8a and vertical support parts 8b, 8 hanging from both ends of the horizontal support part 8a.
Consists of c. Cutouts 8d and 8e that open downward are formed at the lower ends of each of the vertical supports 8b and 8c, and the cutouts 8d and 8e are engaged with the mainspring winding shaft 19 while being straddled onto the drive case 21. It is placed in such a manner that On the other hand, a support protrusion 8f is provided on the upper center surface of the horizontal support part 8a, and this 8f is connected to the face panel 9.
Install by inserting it into the hole provided on the rear back side. Also,
An engaging protrusion 10 is integrally formed on the upper part of one vertical support part 8c.

On the other hand, the front face panel 9 is provided with an eye portion 9a and a tooth portion 9b, which are visible from the outside through the openings 6 and 7 shown in FIG. Therefore, as shown in FIG. 4B, when walking, as the flat plate 35 provided on the forefoot 3a moves back and forth, the engagement protrusion 10 that comes into contact with the rear upper end periodically swings back and forth (in the direction of arrow f). urge The panel 9 moves up and down repeatedly with respect to the openings 6 and 7, thereby diversifying the facial expressions.

Although FIG. 3 shows only the left side of the toy, the position of the eccentric pin 27b attached to the outside of the flat plate 27a of the cam-shaped drive member 26 on the right side is symmetrical to that on the left side, that is, 180 degrees. ° Exactly similar to the left side, except that it protrudes in a rotated position.

FIGS. 4 and 5 illustrate how the walking legs 3a, 3b attached as described above are driven by the drive mechanism.

FIG. 4 shows the forefoot for walking 3a, and A to D represent the states when the cam-shaped drive member 26 is rotated by 90 degrees in the direction of arrow e from the state of A. The accompanying foot movements are represented by arrows df and dr. The front leg 3a for walking is indicated by the arrow df,
It can be seen that it reciprocates back and forth using the pin 45 as a fulcrum like dr.

FIG. 5 also shows the walking hind leg 3b, and A to D in FIG. 5 correspond temporally to A to D in FIG. 4. Here, the notch 48 of the hind leg drive member 31 is guided relative to the pin 25 with respect to the movement of the cam-like drive member 26, and the guide groove 39 of the upper part of the hind leg 3b for walking
is guided by the pin 46 and moves up and down and back and forth. For this reason, the hind legs 3b move in an ellipse, including up and down movements, as well as back and forth reciprocating movements like the front legs 3a, as shown by the arrow d.

Therefore, for example, when moving forward using the left walking legs 3a and 3b, the toy is inclined by an angle θ with respect to the walking surface E as shown by the dashed line in FIG. The foot part 3h supports the main body to completely prevent it from falling over, and the right leg for walking is completely raised from the walking surface, so it does not interfere with walking unlike conventional four-legged toys. Therefore, the stride length of the left foot for walking becomes the amount of forward movement of the main body, allowing efficient walking.

(Effects of the invention) As is clear from the above explanation, the invention includes a main body with a built-in power source, a main body located at the bottom of the main body near the center in the left-right direction, and left and right sets of legs moving back and forth alternately. The main body has walking feet that walk while tilting from side to side, and supporting feet that are located on both outer sides of the walking feet and have substantially the same shape as each of the feet and provide support when the main body is tilted. , when modeling a multi-legged creature such as a science fiction space animal, the appearance will not be unnatural, and the leg that does not contribute to walking on one of the left and right walking legs will be replaced by the leg that contributes to walking on the other. Since the walking ability is not hindered in any way, the walking speed is fast, and even on sloped walking surfaces to the left and right, the user can walk stably without falling over, so it can be used regardless of the walking location. It is possible to dramatically expand the range of toys, and provide toys that are rich in interest and fun for children and others, and that they will never get tired of.
