Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an animal activity toy in which, for example, a toy body formed in the shape of a duck exhibits movements similar to the ecological movements of a duck.

[Conventional technology]

Conventionally, this type of animal activity toy, for example, as described in Japanese Utility Model Publication No. 37-3169, has a toy body that simultaneously moves the wings on both sides up and down to make a flapping motion and the neck body. As described in Japanese Utility Model Publication No. 30-14026, the toy body opens and closes its mouth at the same time as it rotates its neck, and the wing bodies on both sides open and close. A structure in which the oscillator moves up and down is known.

[Problem that the invention attempts to solve]

According to the structures described in the above publications, the wing bodies on both sides only move up and down at a constant speed, and the neck body only rotates left and right at a constant speed. .

Therefore, in this type of animal activity toy, each movement is simple and has little variability, and if the toy is formed to imitate the shape of a bird such as a duck, it is difficult to understand the ecological behavior of a duck. The problem is that they are very different and it is difficult to arouse interest.

Therefore, the present invention was developed in view of these points, and the running motion of the toy body and the up-and-down movement of the neck are related to each other by changing the speed, in other words, the toy body moves slowly. When moving at high speed, the neck body moves up and down slowly and the wing body flaps slowly, and when the toy body moves at high speed, the neck body is tilted forward and the head is lowered. The object of the present invention is to provide an interesting animal activity toy that can make the body face forward and flap its wings at a high speed to perform movements similar to ecological movements.

[Means for solving problems]

The animal activity toy of the present invention includes a toy body 1 which is formed in the shape of a bird and has a built-in machine frame 10, and a toy body 1 which is pivotably mounted on the machine frame 10 and has wheels 76 at both ends.

, a cam disk 51 having a pushing ridge 55 on its inner side for pushing the interlocking shaft 62, and a pair of wing bodies pivotably supported on both sides of the machine frame 10 so as to be rotatable in the vertical direction. 17, and an operating protrusion 77 which is fixed to the axle 75 and moves the pair of blades 17 up and down via a swinging piece 78.

[Effect]

According to the animal activity toy of the present invention, when the electric motor 11 is driven, the first and second switching interlocking impellers 61 and 63 that are gear-engaged with the electric motor 11 are rotated.

Then, the rotating shaft 50 that is meshed and interlocked with this first switching interlocking gear 61 is rotated, and this rotating shaft 50
The cam disk 51 of the cam disk 51 is rotated, the cam 40 is forced to rotate intermittently by the plurality of protrusions 54 on the outer surface of the cam disk 51, and the neck body 25 to which the cam plate 40 is attached is intermittently rotated. The head is moved back and forth at a relatively slow speed and the head is shaken back and forth.

Further, the rotation of the first switching interlocking gear 61 rotates the first wheel drive gear 73, and the wheels 76 on both sides are rotated via the axle 75, so that the toy body 1 moves relatively slowly. Reduces the movement of driving straight at a certain speed. At the same time, the operating protrusion 77 fixed to the axle 75 is rotated, and the operating protrusion 77
The wing bodies 17 on both sides are moved up and down in a relatively slow motion via the swinging pieces 78, and the wing bodies 17 exhibit a flapping motion.

Therefore, the toy object 1 moves forward at a relatively slow speed while shaking its neck back and forth and flapping its wings.

Next, due to the rotation of the cam disk 51, the engagement guide edge 53 of the cam disk 51 engages with the cam plate 40, and this engagement guide edge 53 gradually forcibly rotates the cam plate 40 to a large extent, causing the neck The body 25 is forcibly rotated, the neck body 25 is brought down to a substantially horizontal position, and at the same time, the head body 26 is pushed up by the support piece 35 and rotated to the side opposite to the neck body 25, and is positioned forward. be done.

Therefore, the toy object 1 suddenly lowers its neck and lifts its head in a forward motion.

Along with this operation, the pushing flange 55 on the inner surface of the cam disc 51 forcibly pushes the interlocking shaft 62 in the axial direction, and the first switching drive gear 61 fixed to the interlocking shaft 62 shifts to the first switching drive gear 61. The second switching interlocking gear 63 is disengaged from the wheel drive gear 73 and meshes with the second wheel drive gear 74 instead of the first switching interlocking gear 61, and the second switching interlocking gear 63 and the second wheel drive The engagement of the gears 74 causes the axle 75 to rotate at a relatively high speed, and the wheels 76 of the axle 75 to rotate at a relatively high speed, so that the toy object 1 rapidly moves straight ahead at a relatively high speed.

Along with this, this axle 7 rotates at high speed.
Since the actuating protrusion 77 fixed to the actuator 5 is also rotated at a relatively high speed, the actuating protrusion 77 causes the swinging piece 78 to swing up and down at a high speed. The pair of wing bodies 17 are moved up and down at a fast speed and exhibit a flapping action with a fast amplitude.

Accordingly, the toy object 1 changes from a normal running motion to a motion of moving forward by rapidly lowering its neck and flapping its wings at a high speed by the switching operation of the switching mechanism.

Then, the second interlocking gear 67 meshed with the first switching interlocking gear 61 is rotated, and the buzzing gear 70 provided coaxially with this second interlocking gear 67 is eccentrically rotated. The ringing piece 71 engaged with the tooth 70 is intermittently brought into sliding contact with the tooth, and this is amplified and resonated by the ringing body 72.

Further, due to the rotation of the second interlocking gear 67, the drive gear 52 is rotated via the intermediate gear 69 coaxial with the second interlocking gear 67.
The cam disk 51 of the rotating shaft 50 to which the cam plate 40 is fixed is rotated, and the protrusion 54 following the engagement guide edge 53 formed on the outer surface of the cam disk 51 is rotated as a unit. is forcibly rotated intermittently, and the pushing body 38 connected to this cam plate 40 via a coil spring 48 is similarly rotated, and the pushing shaft 42 of this pushing body 38 pushes the neck body 2.
5 is a coil spring 37 with the support shaft 24 as a fulcrum.
It moves back and forth intermittently with a relatively slow amplitude against the pressure, giving the appearance of shaking the neck back and forth. That is, as the cam disk 51 rotates with respect to the cam surface 43 of the cam plate 40, the first step 53a between one end of the engagement guide edge 53 of the cam disk 51 and one protrusion 54 6, the cam plate 40 is not pushed and the neck body 25 is held almost vertically. However, as shown in FIG. When it engages with the cam surface 43 of the cam plate 40, the cam plate 40 is gradually rotated in accordance with this rotation, and the push shaft 42 of the push body 38 pushes the neck body 25 slightly forward. 54 passes the cam plate 40, the neck body 25
When the cam plate 40 is returned to the rear by the restoring force of 7 and is located at the second step 543b between the rotating protrusion 54 and the other protrusion 54, the cam plate 40 40 and therefore,

When the cam plate 40 and the pushing body 38 are engaged with the cam surface 43 of the
5 forward again and push this other protrusion 54
passes through the cam plate 40, the neck body 25
is returned backwards.

Furthermore, the rotation of the first switching interlocking gear 61 causes the first wheel drive gear 73 to rotate, and the wheels 76 to rotate via the axle 75 fixed to the first wheel drive gear 73. , together with the other wheel 7, the toy body 1 moves straight at a relatively slow speed. At the same time, the actuating piece 77 fixed to the axle 75 is rotated, and the actuating piece 77 moves the blades 17 on both sides connected via the swinging piece 78 and the lifting piece 80 to the coil spring 23.
The wings 17 are moved up and down in a relatively slow motion against the pressure, and the wing body 17 exhibits a flapping motion.

Therefore, the toy concrete 1 is as shown in FIG.
It moves forward at a relatively slow speed while shaking its neck up and down and flapping its wings.

Next, when the other protrusion 54 passes through the cam plate 40 as described above due to the rotation of the cam disk 51,
The engagement guide edge 53 of the cam disk 51 engages with the cam surface 43 of the cam plate 40 from the other end, and this engagement guide edge 5
3, the cam plate 40 is gradually forcibly rotated (counterclockwise in FIG. 7), and the neck body 25 is coiled by the pushing shaft 42 of the pushing body 38, which is integrated with the cam plate 40. It is forcibly rotated about the support shaft 24 against the spring 37, and the neck body 25 is tilted almost horizontally as shown in FIG. When the neck body 25 is tilted horizontally, the head body 26 is gradually pushed up by the support piece 35 via the shaft rod 34, so the head body 26 supports the neck body 2 with the connecting shaft 28 as a fulcrum.
5, and the face 29 is positioned forward.

Therefore, the toy body 1 exhibits an action of rapidly lowering its neck.

Further, when the neck body 25 is horizontally tilted and the head body 26 is turned forward, the other end of the engagement guide edge 53 engages with the cam surface 43 of the cam plate 40, and the inside of the cam disc 51 The guide edge 56 of the pushing protrusion 55 formed on the side surface is connected to the engaging portion 6 of the sliding tube 65.
4, the engaging portion 64 is pushed by the tapered guide edge 58, and the pushing projection edge 5
5, and the interlocking shaft 6 to which this sliding tube 65 is fixed
2 is forcibly slid in the axial direction against the coil spring 66, and the first interlocking gear 60 fixed to the interlocking shaft 62 meshes and rotates while the gear interlocking mechanism 59
The meshing position is moved and rotated along the gears of
Further, the first switching interlocking gear 61 coaxial with the first interlocking gear 60 changes the meshing position with the second interlocking gear 67 as it moves in the axial direction, and rotates the second interlocking gear 67. However, a large-diameter second switching interlocking gear 63 that is separated from the first wheel driving gear 73 and is fixed to the interlocking shaft 62 in place of the first switching interlocking gear 61 is connected to the first wheel driving gear 73. The axle 75 is engaged with a coaxial second wheel drive gear 74, and the axle 75 is rotated at a relatively high speed by the engagement of the second switching interlocking gear 63 and the second wheel drive gear 74.
The wheels 76 of No. 5 are rotated at a relatively high speed, and the wheels 76
At the same time, the toy body 1 rapidly moves straight ahead at a relatively high speed.

Since the actuating protrusion 77 fixed to the axle 75 is also rotated at a relatively high speed, the actuating protrusion 77 causes the swinging piece 78 to swing up and down with a fast amplitude. The lifting piece 80 connected to the swinging piece 78 is also raised and lowered in a fast motion, and therefore the wing body 17 connected to the lifting piece 80 is moved up and down at a fast speed against the coil spring 23, and flaps with a fast amplitude. exhibits.

Further, in this case, since the second interlocking gear 67 is interlocked, the toy body 1 continues to make a chirping motion.

Therefore, the toy concrete 1 changes from the normal traveling motion shown in FIG. 8 to the switching action of the switching mechanism, and as shown in FIG. Exhibits the motion of running.

Next, when the pushing flange 55 is disengaged from the engaging portion 64 of the sliding tube 65 due to rotation of the cam disk 51, the interlocking shaft 62 is pushed by the restoring force of the coil spring 66 and returned. The second switching interlocking gear 63 is disengaged from the second wheel driving gear 74, and the first switching interlocking gear 61 again meshes with the first wheel driving gear 73. It returns to the motion of moving forward at a relatively slow speed while rocking back and forth and flapping its wings.

Further, in the above case, by preliminarily deviating the wheels 7 of the locking disc 6 by a predetermined angle, the toy object 1 exhibits the movement of turning at a predetermined turning angle while exhibiting each of the above-mentioned movements.
