[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a walking toy that uses a crank mechanism to walk.

[0002]

[Prior art]

 As walking toys, there is a toy that uses a crank mechanism to perform walking movements that imitate crustaceans, such as crabs.

In such toys, a toy body having a motor mounted thereon is provided with a crankshaft portion that rotates by receiving the power of the motor, and each end portion of the crankshaft is perpendicular to the shaft center. A crank mechanism is employed in which a pair of links extending in the left-right direction, which is a direction, are connected, and the middle portion of these links is supported by the toy body slidably in the longitudinal direction. A leg for walking is provided at the extended end of each link, and the forward side and the backward side with the middle part of each link as a fulcrum obtained by rotating the crank shaft with a motor are provided. The swinging motion creates a crab-like movement in the legs.

[0004]

[Problems to be solved by the device]

 However, although the structure in which the link is simply connected to the crankshaft allows the walking motion imitating a specific creature to be performed, the motion is monotonous and there is a drawback that it is not interesting as a toy. The present invention has been made in view of such circumstances, and its purpose is to provide a walking toy that is highly entertaining and can change its movement.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the walking toy of the present invention is equipped with a drive source device, and a toy body is provided on both sides of which an output shaft that rotates by receiving the power of the drive source device protrudes on both sides. Each output shaft is connected to a crank plate having a plurality of first connecting portions on the front surface at different positions around the axis of the output shaft, and has one end extending toward the crank plate and a walking leg. A plurality of links, each having a second end and an intermediate part that is slidably supported in the longitudinal direction, are provided at respective parts on both sides of the toy body that sandwich the crank plate, and the links are inserted into one end of each of the links. And a second connecting portion that is detachably connected to the first connecting portion of the crank plate for supporting each link on the crank plate through the insertion hole of each of the links. Link connection position for the crank plate In providing the connection operator for changing.

[0006]

[Action]

 According to the walking toy of the present invention, the connecting operator is used to select a connecting portion at an arbitrary position from the first connecting portion on each of the crank plates on both sides of the toy body, and to connect the connecting portion and the crank plate. If the connecting ends of the pair of extended links are connected, the system necessary for walking is established.

After that, when the drive source device is operated, the crank plates on both sides of the toy body are rotated, and a pair of links on both sides of the toy body are drawn with the middle part as a fulcrum, with the shaft center of the crank plate as a fulcrum. It swings according to the trajectory of the link connecting portion. This swinging motion is transmitted to each of the walking legs, causing the toy body to walk as if a crab were walking.

Here, when changing this movement, the connecting operator is used so as to change the combination of the first connecting portions on both sides of the toy body selected so far, that is, to change the link connecting position. One end of each pair of links on both sides of the toy body may be connected to the crank plate.

That is, the first connecting portions on both sides of the toy body are located at different positions around the axis of the output shaft. This difference in position acts as the size of the stroke of the walking leg on both sides of the toy body and the phase of the movement of the walking leg, so the toy body is operated in a different motion from the initial walking motion. . In other words, the toy body can make interesting movements for multiple types of shapes depending on the combination of link connection positions.

As a result, pin holes are provided in different parts around the axis of the output shaft 10.

The hole portions 19 are fitted into both ends of the output shaft 10 so that the pin holes are at predetermined positions, and the crank plates 17, 17 are entirely installed in front of and behind the main body. Specifically, the crank plates 17, 17 are arranged such that the pin hole positions are “A and A”, “B and B”, “C and C”, and “D and D” at the same position. Is positioned and fixed.

On the other hand, on both sides of the main body 1, a pair of support bosses 21 and 21 for fulcrums are projectingly provided on both sides sandwiching the crank plate 17. In this embodiment, in order to distinguish between the front supporting boss and the rear supporting boss of the main body 1, the front supporting boss of the main body 1 is suffixed with "a", and the rear part of the main body 1 is attached. "B" is added to the ending of the support boss of.

Each of the support bosses 21 a, 21 a and the support bosses 21 b, 21 b extends along the width direction at the tip end surface of the pedestal portion 22 projecting on the left side of the side portion of the main body 1 and the right end portion of the main body 1. Is provided on the front end surface of the frame-shaped pedestal portion 23. Each pedestal portion 22, 23 has an overall height corresponding to the distance from the side portion of the main body 1 to the crank plate 17.

The front support bosses 21 a, 21 a and the rear support bosses 21 b, 21 b are both arranged on a horizontal line that intersects with the axis of the output shaft 10 and extends in the horizontal direction, and has the same distance from the output shaft 10. It is arranged in the part that becomes.

The middle portion of the pair of link plates 24a, 24a is slidably supported by the front support bosses 21a, 21a. The intermediate portions of the pair of link plates 24b, 24b are also slidably supported by the rear support bosses 21b, 21b in a symmetrical relationship with the link plates 24a, 24a. Equivalent to a link).

Specifically, the link plates 24a, 24a and the link plates 24b, 24b are each provided with an elongated hole 25b along the longitudinal direction at the plate surface portion between them. Then, by inserting the long holes 25b of the link plates into the support bosses and by inserting the link stoppers 27c which can be inserted into the bosses into the boss ends projecting from the long holes 25b, the respective link plates are inserted. 24a, 24a and link plates 24b, 24b are supported slidably in the longitudinal direction.

The outer ends of the link plates 24 a, 24 a and the outer ends of the link plates 24 b, 24 b extend to the left and right sides of the main body 1. At the ends of the link plates 24a, 24a, two leg portions 25 (corresponding to the walking legs of the present application) imitating a crab leg are provided so as to be symmetrical with respect to the main body 1. . In addition, 25a shows the connection part for connecting the leg parts 25 and 25 comrades. Further, two end portions 26 (corresponding to a walking leg of the present application) imitating a crab leg are also provided at the ends of the link plates 24b, 24b so as to be symmetrical with respect to the main body 1. . The legs 25 and 26 have substantially the same shape. However, reference numeral 26a indicates a connecting portion for connecting the leg portions 25, 25 to each other.

The inner ends of the link plates 24 a, 24 a extend to the crank plate 17 in the front part of the main body 1. The inner ends of the link plates 24b, 24b extend to the crank plate 17 at the rear of the main body 1. A pin insertion hole 27 (corresponding to the insertion hole of the present application) having a diameter slightly larger than the inner diameter of the pin hole is provided at the end of each of the link plates 24a, 24a and the link plates 24b, 24b. There is. In this embodiment, in order to distinguish the pin insertion holes of the link plates 24a, 24a from the pin insertion holes of the link plates 24b, 24b, the pin insertion holes of the link plate 24a are suffixed with "a", The pin insertion hole of the link plate 24b has a suffix "b".

The end portions of the link plates 24a, 24a are selectively connected to the pin holes 20a to 20d of the crank plate 17 on the front part of the main body by using the connection operation tool 28a (corresponding to the connection operation element of the present application). The ends of the fixing and link plates 24b and 24b can be selectively fixed to the pin holes 20a to 20d of the crank plate 17 at the rear of the main body by using the connection operation tool 28b (corresponding to the connection operator of the present application). Is done. Specifically, the following operation tool structure is used to fix the ends of the front and rear link plates.

That is, each of the connection operation tools 28a and 28b is configured by providing the insertion boss 30 (corresponding to the second connection portion of the present application) at the tip of the cylindrical knob 29 which can be picked by fingers. The insertion boss 30 is insertable into the pin holes 20a to 20d and has a length dimension longer than the thickness dimension of the two linked link plates 24a, 24a (or link plates 24b, 24b).

As a result, on the front side of the main body 1, the ends of the link plates 24a, 24a are aligned so that the pin insertion holes 27a, 27a are aligned with one of the selected pin holes 20a-20d. After the parts are placed on the front surface of the crank plate 17, the insertion boss 30 is inserted into the pin hole selected from the pin insertion hole 27a, and the connecting operation tool 28a is stopped on the crank plate 17, so that the selected crank The pair of link plates 24a, 24a can be fixed at the position.

Similarly, on the rear side of the body 1, the ends of the link plates 24b and 24b are aligned so that the pin insertion holes 27b and 27b are aligned with one of the selected pin holes 20a to 20d. After the portion is overlaid on the front surface of the crank plate 17, the insertion boss 30 is inserted into the pin hole selected from the pin insertion hole 27b, and the connecting operation tool 28b is stopped on the crank plate 17, so that the selected crank The pair of link plates 24b, 24b can be fixed at the position. As a result, the link connection position with respect to the crank plates 17, 17 can be arbitrarily changed. Next, the operation of the walking toy configured as above will be described. An example will be described in which the front and rear link connection positions are set to different positions by “180 °” and the walking toy is walked.

First, the inner ends of the link plates 24 a, 24 a slidably supported by the support bosses 21 a, 21 a are overlapped with the pin hole portions indicated by “A” of the front crank plate 17. Then, the pin insertion holes 27a and 27a are aligned with the pin hole 20a.

Then, the insertion boss 30 of the connecting operation tool 28a is inserted from the pin insertion hole 27a into the pin hole 20a, and the connecting operation tool 28a is fixed to the crank plate 17. As a result, the link connection position at the front of the main body is set.

After that, similarly, the inner ends of the link plates 24b, 24b slidably supported by the support bosses 21b, 21b are pinned by the pin "C" of the front crank plate 17. The holes are overlapped with each other and the pin insertion holes 27b, 27b are aligned with the pin hole 20c. Then, the insertion boss 30 of the connection operation tool 28b is inserted from the pin insertion hole 27b into the pin hole 20c, and the connection operation tool 28b is fixed to the crank plate 17. As a result, the link connection position on the front of the main unit is set, and the system necessary for walking is set.

After that, the switch lever 5 is rotated in the ON direction. Then, the motor 9 is activated by the electricity supplied from the dry battery 3. As a result, the rotation of the motor 9 is transmitted to the worm 12, the worm wheel 14, the small spur gear 15, and the large gear 16 in this order as shown in FIG. It is transmitted and the front and rear crank plates 17, 17 are rotated. As the crank plates 17, 17 rotate, the front and rear link plates 24a, 24a and the link plates 24b, 24b of the main body 1 start oscillating motion.

That is, the link plates 24a, 24a and the link plates 24b, 24b have link connection positions drawn with the shaft center (output shaft 10) of the crank plate 17 as a fulcrum with the support bosses 21a, 21b as an intermediate fulcrum. It swings according to the movement trajectory of. Specifically, the other ends of the link plates 24a and 24b oscillate along the loci shown by the solid line of reference character α shown in FIG. 5, respectively. Then, these swing motions are transmitted to the leg portions 25 and 26 from the link plate 24a and the link plate 24b.

Since the pin hole positions on the front and rear crank plates 17, 17 are “180 °” in phase, and the pin hole positions are farthest from the axial center (output shaft) of the crank plate 17 ( The front: A, the rear: C), the largest stroke produces a crab-like movement, that is, the legs 25 and 26 kick out alternately on the left and right sides, respectively. At this time, the connecting portions 25a and 26a do not hit each other (because the connecting portions 25a and 26a are set at positions where they do not collide). According to this combination of pin hole positions, the walking toy walks in a straight line with the largest stroke. If this movement is desired to be changed, the combination of the link connecting positions on the crank plates 17, 17 on both sides of the main body 1 selected so far may be changed.

For example, when changing from the combination of “front: A” and “rear: C” to the combination of “front: A” and “rear: A”, from the crank plate 17 at the rear part, the connecting operation tool 28b is pulled out, this time, the end portions of the link plates 24b, 24b are overlapped with the pin hole portions indicated by "A" of the crank plate 17, and the connecting operation is performed from the pin insertion holes 27b, 27b toward the pin hole 20a. The insertion boss 30 of the tool 28b may be inserted.

According to such a combination, the front and rear crank plates 17, 17 have the same pin hole position, and the pin hole position is farthest from the axial center (output shaft) of the crank plate 17, Only the main body 1 reciprocates up and down with the largest stroke without moving. In other words, in the walking toy, only the main body 1 moves largely up and down while stopped, and a state in which a crab is dancing at the same position is created.

When the combination of “front: A” and “rear: B” is changed, the pin hole positions on the front and rear crank plates 17, 17 are “90 °”, which are in phase with the rotation direction of the crank plate 17, Also, due to the difference between the position farthest from the shaft center (output shaft) of the crank plate 17 and the position closest to it, the walking toy can move as if a crab swivels to the right. Be created.

When the combination of “front: A” and “rear: D” is changed, the pin hole position in the front and rear crank plates 17, 17 is “90 °”, which is the direction opposite to the rotation direction of the crank plate 17. Due to the difference between the position farthest from the shaft center (output shaft) of the crank plate 17 and the position closest to the shaft center of the crank plate 17 caused by the position of the pin hole, the walking toy walks as if the crab turns to the left. Such a movement is created. Further, the following movements are obtained when the front portion is set to a position closest to the shaft center (output shaft) of the crank plate 17 in combination.

That is, when the link connection position is changed to a combination of “front: B” and “rear: A”, the walking toy produces a motion in which a crab walks while turning to the left. Changing to a combination of "front: B" and "rear: A" creates a motion in which only the main body 1 moves up and down slightly while it is stopped. Changing to a combination of "front: B" and "rear: C" will give the walking toy a movement in which the crab will walk while turning to the right. Changing to a combination of "front: B" and "rear: D" produces a walking motion in a straight line with a small stroke. However, due to the difference in the link connection position, the walking toy is operated in a different motion from the initial walking motion. Therefore, it is possible to bring interesting movements to the walking toy and improve the entertainingness according to a plurality of types depending on the combination of the link connection positions on both sides of the main body.

In one embodiment, the end portion of the link plate is fixed by inserting the boss of the connection operation tool into the pin hole of the crank plate, but the crank plate side is made the boss on the contrary. The end of the link plate may be fixed by forming a pin hole on the connection operation tool side. In the above-described embodiment, the present invention is applied to a walking toy imitating a crab, but the present invention is not limited to this, and the present invention may be applied to a walking toy imitating the movement of another living thing.

[0041]

[Effect of device]

 As described above, according to the present invention, the movement of the walking toy, which has been monotonous in the past, can be variously changed by combining the link connection positions on both sides of the main body. In other words, it is possible to provide interesting movements for a plurality of types of forms depending on the combination of link connection positions, and it is possible to provide a walking toy that is rich in interest.
