DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an active animal toy, for example, one in which an animal such as a dog performs active movements such as walking or sitting.

(Prior Art) Conventionally, this type of active animal toy that allows animals such as dogs to walk or sit has been disclosed, for example, in Japanese Patent Publication No. 55-20707, Japanese Utility Model Publication No. 57-5035, or Japanese Utility Model Publication No. 57-5035. A structure described in Japanese Patent No. 59-2393 is known. These conventional active animal toys have a structure in which walking or sitting movements are performed by switching between forward and reverse rotation of the electric motor or by changing the rotation direction of the gear drive mechanism.

In addition, in conventional active animal toys, in order to perform the sitting motion, a constantly rotating crank arm or the like is engaged with an engaging recess such as a lever that tilts the hind legs to rotate the hind legs in the sitting direction. A structure is adopted that operates the system.

(Problems to be Solved by the Invention) In the above-mentioned conventional active animal toy, a gear drive mechanism is used to switch the electric motor between forward and reverse rotation, or to switch the rotation direction of the gear drive mechanism. In addition, with a structure in which levers are operated by rotating the crank arm in the forward and reverse directions, there is a problem in that during walking motion, contact noise is generated when the crank arm touches the crank arm every time it rotates, which increases noise. are doing.

The present invention has been made in view of the above-mentioned problems, and the toy object, which is formed in the shape of an animal such as a dog, moves forward for a predetermined period of time without changing the direction of rotation of the gear drive, and then stops. While tilting the hind legs forward and sitting down, the toy body is supported by the rear part of the hind legs and the tail body, the tip of which has been placed on the ground in advance, and the left and right front legs are lifted up. The toy body is raised up, the left and right front legs move up and down at the same time, and the hind legs are linked, and the interaction between the hind legs and the tail body causes the toy body to move up and down as a whole, causing the so-called dog to chin-chin. The object of the present invention is to provide an active animal toy that exhibits movements in which the head and body move back and forth while performing such movements, and which makes less noise.

3, and the front leg drive mechanism 3.
3, the toy body 1 is supported by the rear leg bodies 10 and the tail body 15, and the head body 8 is moved back and forth when the toy body 1 is seated.

(Function) In the active animal toy of the present invention, the input gear 29 of the interlocking switching mechanism 28 is rotated by the drive of a power source such as an electric motor, and the output gear 4 is interlocked with the input gear 29.
6 is rotated. Further, the switching gear 30 is rotated in conjunction with the rotation of the output gear 46, and the front leg drive mechanism 33 is operated in conjunction with the switching gear 30.
In this case, one crank arm 34 and the other crank arm 35 are moved onto different axes and rotated in conjunction with each other with their positions shifted. By the interlocking rotation of the one crank arm 34 and the other crank arm 35, the left and right front leg frames 4 supported by the crank arms 34 and 35 are alternately moved back and forth, and the left and right front leg frames 4
The left and right rear leg frames 5 connected to the toy body 1 move forward and backward alternately in conjunction with the left and right rear leg frames 5, and the toy object 1 exhibits a forward walking motion by the left and right front leg bodies 9 and the left and right rear leg bodies 10.

In addition, at this time, due to the rotation of the output gear 46, the tail frame 14 is caused to hang downward by the actuating mechanism 80, so that the toy body 1 is moved downward from the tail body 15.
For a predetermined period of time, the robot exhibits the motion of walking forward while hanging down.

Next, the output gear 46 of the interlocking switching mechanism 28
When the relay gear 82 of the actuating mechanism 80 is further rotated by the rotation, the tail frame 14 is gradually lifted and rotated upward, and assumes an extended state in an upwardly inclined state.

Further, following the upward rotational movement of the tail frame 14, the left and right rear leg frames 5 are forcibly rotated forward by the rotation of the first cam 83, and the center of gravity of the toy object 1 is moved rearward. By being moved, the rear part of the toy body 1 is placed on the floor and the tip of the tail frame 14 is placed on the floor. Therefore, the toy object 1 stops its forward walking motion and thrusts the left and right hind legs 10 forward, and the toy object 1
It is supported by the rear part of the tail body 15 and the tip of the tail body 15, and exhibits the motion of sitting on its buttocks.

Further, as the toy body 1 shifts to the above operation, the pushing cam 92 of the actuating plate 86 gradually pushes the electric motor gear 30 in the axial direction due to the rotation of the third cam 85, and this switching gear 30 is pushed. When the switching gear 30 is moved, the meshing of the switching gear 30 is switched, so that one crank arm 34 and the other crank arm 35 are converted to be on the same axis, and are rotated in conjunction with each other in this state. When the crank arms 34 and 35 are rotated by the rotation of the switching gear 30 as described above, the left and right front leg frames 4 are simultaneously moved up and down in the same position, and are linked to the movement of the left and right front leg frames 4. As a result, the left and right rear leg frames 5 are moved up and down. Furthermore, in this case, since the toy object 1 is supported by the tail frame 14, it exhibits a vertically bouncing motion in association with the vertical movement of the left and right rear leg frames 5. Therefore, the toy body 1 has left and right rear leg bodies 10.
When the dog is sitting with the front legs sticking out forward, the dog lifts the left and right front leg bodies 9 and simultaneously moves them up and down, bouncing the whole body and repeatedly exhibiting the so-called chin-chin motion for a predetermined period of time.

In addition, during the above-mentioned chin-chin motion, the head frame 3 is rotated forward and backward, and when the toy body 1 is seated with the left and right rear legs 10 protruding forward, the left and right front legs 9 is raised and moved up and down at the same time, bouncing the whole body, moving the head body 8 back and forth, wide opening and closing the mouth part 136, and repeating the behavior of a dog for a predetermined period of time.

Next, when the second cam 84 is further rotated, the tail frame 14 is rotated downward. In addition, the first
When the cam 83 is further rotated, the left and right rear leg frames 5 are rotated back to the rear, and the center of gravity of the toy body 1 is moved forward and returned to the front.
The rear part of the toy 1 separates from the landing surface, and therefore, as described above, the toy 1 in the seated state gets up again and moves forward again with the left and right front legs 9 and the left and right hind legs 10. Prepare for. Also, the third cam 8
5 is further rotated, the actuating plate 86 engaged with this third cam 85 rises, and the pushing cam 92
The pressure on the switching gear 30 is gradually released, and the switching gear 3
0 is moved by the compressed spring 53 and separated from the output gear 46, the back and forth movement of the head 8 of the toy object 1 is interrupted, and the switching gear 30 moves the head 8, which is located on the same axis, to move away from the output gear 46. The crank arm 34 and the other crank arm 35 roll back and forth again, shifting their positions, and in this state they are rotated in conjunction with each other. Therefore, the toy object 1 moves forward again by the interlocking movement of the left and right front legs 9 and the left and right rear legs 10 with the tail body 15 hanging down.

The rotating shaft 93 that fixed the first engagement lever 94 is rotated in conjunction with the rotating shaft 93, and the other link 98 of the link mechanism 96 pushes and rotates the bent portion of the crankshaft 38. The crank arms 39 at both ends of the shaft 38 are simultaneously rotated forward. This forward rotation of the crank arm 39, together with the repulsive force of the coil spring 99, forces the left and right rear leg frames 5 supported by the crank arm 39 to rotate forward, and the toy body 1 The storage case 1 of the toy object 1 is moved by moving the center of gravity backward.

Furthermore, when the toy body 1 shifts to the above-mentioned operation and the engagement protrusion 89 is pushed downward by the rotation of the third cam 85, this operating plate 86 81 via the guide elongated groove 87, and the extension plate portion 90, which is integrated with this operating plate 86, is similarly lowered relative to the mounting shaft 41 via the guide elongated hole 91, and this extension plate portion 90 The push cam 92 provided inside the pressure receiving part 5 of the switching gear 30
1 is gradually pushed in the axial direction, and this switching gear 30 is moved along the mounting shaft 41 in a direction toward the output gear 46 against the coil spring 53. That is, when the switching gear 30 is pushed in the axial direction by the pushing cam 92, the engaging protrusion 5 of the switching gear 30
2 gradually enters the engagement recess 43 formed in the bearing body 42 of the output gear 46 against the coil spring 53, and the switching gear 30 approaches the output gear 46. The switching gear 30 is a front leg drive mechanism 33.
is disengaged from the first interlocking gear 31, and the second interlocking gear 3 replaces the first interlocking gear 31.
It meshes with 2. When this switching gear 30 is meshed with the second interlocking gear 32, the second interlocking gear 32 is rotated, and the clutch gear 71 formed on the outer surface of the second interlocking gear 32 is engaged with the clutch disc body 55. Since it is meshed with a clutch gear 76 formed on the inner surface of the disc 73, the clutch disc body 5
5 is rotated integrally with the second interlocking gear 32. When this clutch disk body 55 is rotated,
Crankshaft 54 to which this clutch disk body 55 is attached
The engagement protrusion 78 formed at the tip of the gear support 77 of the clutch disc body 55 is rotated by itself approximately 180 degrees and engages with the locking protrusion 61 of the first interlocking gear 31, and the first interlocking gear 31 is engaged. One crank arm 34 and the other crank arm 35 of the gear 31 are positioned on the same axis, and are rotated in conjunction with each other in this state.

Then, as described above, the switching gear 30 is meshed with the first interlocking gear 32, and the second interlocking gear 32 is engaged with the switching gear 30.
When the crank arms 34 and 35 are rotated, the left and right front leg frames 4 are simultaneously moved up and down in the coaxial position around the support rod 37, and are linked to the movement of the left and right front leg frames 4. Left and right interlocking rods 4
0 is simultaneously linked up and down, and this left and right linking rod 40
With this action, the left and right rear leg frames 5 are attached to the crank arm 39 of the crankshaft 38 with their heel portions 5a touching the ground.
It moves up and down around the center. Also, in this case,
Since the toy object 1 is supported by the tail frame 14 made of a spring member, it exhibits an upward and downward bouncing motion in association with the vertical movement of the left and right rear leg frames 5. Therefore, as shown in FIGS. 4 and 6, when the toy body 1 is sitting with the left and right rear legs 10 protruding forward, the left and right front legs 9
The robot lifts up the dog and moves it up and down at the same time, making the whole body bounce for a predetermined period of time.

In addition, during the above-mentioned chink operation, the operating gear 120 is interlocked and rotated by the second interlocking gear 32 via the relay gear 122, so that the rotation of the operating gear 120 causes the operating gear 120 to An integral, substantially semicircular pinion 119 rotates while intermittently meshing with the rack 118, and presses the slider 116 forming the rack 118 downward. When the slider 116 is pressed downward, the slider 116 is moved by the coil spring 219.
The sounding body 124 is slightly lowered along the guide recess 114 of the guide frame plate 112 against the
When the bellows 125 of the slider 1 is extended and the pinion 119 is disengaged from the engaged rack 118, the slider 1
Reference numeral 16 denotes a bellows 12 which is instantly raised and expanded by the restoring force of a coil spring 129.
5 is contracted, and as a result, the pinion 119 is intermittently engaged and rotated with the rack 118, so that the slider 116 is moved up and down, and the bellows 12
5 is expanded and contracted, so the singing body 124 is played.

Further, when the operating gear 120 is rotated in conjunction with each other as described above, the crankshaft 121 to which the operating gear 120 is attached is rotated, and the operation of the crankshaft 121 causes the crank arm 1 of the crankshaft 121 to rotate.
An interlocking piece 131 connected between the head frame 30 and the head frame 3 is moved back and forth, and the head frame 3 is interlocked and rotated back and forth about the support shafts 133 on both sides. In this case, the head and body frame 3 has its rear opening 3a connected to the body frame 3.
Since the opening is formed with a large diameter so as to create a large step with respect to the neck portion 2a of the
3, as shown by the solid line and chain line in FIG. The neck portion 6a of the body 6 changes in appearance as it expands and contracts back and forth, up and down, and the back changes. Furthermore, due to the back and forth rotation of the head frame 3, the upper jaw body 134 opens and closes the lower jaw body 135, as if opening and closing the mouth part 136.

Therefore, when the toy body 1 is in a sitting state with the left and right rear legs 10 pushed forward, the left and right front legs 9 are lifted up, and these are simultaneously moved up and down, bouncing the whole body while the head body 8 is moved. While moving the mouth part 136 back and forth greatly, the mouth part 136 is opened and closed to emit sound,
The dog exhibits a twitching motion for a predetermined period of time.

Next, when the second cam 84 is further rotated, the second engagement lever 95 engaged with the second cam 84 gradually rotates clockwise in FIG. 7 against the coil spring 110. The reversing gear 102 is rotated counterclockwise in FIG. is rotated clockwise around the support shaft 108, that is, the engaging protrusion 1 is moved from the stopper 104.
09 rotates the driven gear 107 in the direction in which it separates,
The tail frame 14 attached to the driven gear 107 is rotated downward.

Further, when the first cam 83 is further rotated, the first engagement lever 94 engaged with the first cam 83 is rotated clockwise in FIG.
The rotating shaft 93 provided with the engagement lever 94 is rotated in conjunction with the rotation, and the other link 98 of the link mechanism 96 pushes and rotates the bent portion of the crankshaft 38 . The crank arm 39 is simultaneously rotated rearward. As a result, the left and right rear leg frames 5 supported by the crank arms 39 at both ends are rotated back to the rear, and the toy body 1
The center of gravity of the toy concrete 1 is moved forward.
The hinge 18 of the storage case 17 separates from the landing surface, and therefore, as described above, the toy object 1 in the seated state rises again and moves the left and right front legs 9.
Then, the left and right hind legs 10 are used to prepare for forward walking motion again.

Further, when the third cam 85 is further rotated,
The actuating plate 86 engaged with this third cam 85 is pushed upward via its upper engaging protrusion 88,
And it is pushed up vertically via the support shaft 81 and the mounting shaft 41 inserted into the upper and lower guide slots 87 and the guide slots 91, respectively. As a result, the pushing cam 92 formed inside the extension plate part 90 integrated with the actuating plate 86 gradually releases the pressure against the pressure receiving part 51 formed in the boss 50 of the switching gear 30. Furthermore, when the push against the pressure receiving portion 51 is released, the switching gear 30 is moved in a direction away from the output gear 46 along the mounting shaft 41 by the restoring force of the compressed coil spring 53, and the switching gear 30 is moved in a direction away from the output gear 46 along the mounting shaft 41. The portion 51 is returned to the position below the extension plate portion 90 where it is not pushed by the pushing cam 92. Then, the switching gear 30 is disengaged from the second interlocking gear 32 of the front leg drive mechanism 33, and is again engaged with the first interlocking gear 31 instead of the second interlocking gear 32. In this way, when the switching gear 30 separates from the second interlocking gear 32, the driving of the second interlocking gear 32 is stopped, and the above-mentioned head of the toy concrete 1 starts from the rotation of the second interlocking gear 32. The back and forth movement of the body 8, the opening/closing movement of the mouth portion 136, and the ringing movement of the ringing body 124 are interrupted.

Further, when the switching gear 30 that has separated from the second interlocking gear 32 meshes with the first interlocking gear 31 again and the first interlocking gear 31 is driven by this switching gear 30, the first interlocking gear 31 is driven. When the gear 31 is rotated independently and the locking protrusion 61 has been rotated approximately 180 degrees, the locking protrusion 61 is again connected to the crankshaft 5.
It engages with the engagement protrusion 78 of the clutch disk body 55 provided at 4. As a result, one crank arm 34 and the other crank arm 3 located on the same axis
5 rolls back and forth again, shifting their positions, and in this state they are rotated in conjunction with each other. Therefore, the toy object 1 exhibits the action of walking forward again for a predetermined period of time by the interlocking movement of the left and right front legs 9 and the left and right rear legs 10 with the tail body 15 hanging down.

In this way, the toy body 1 repeatedly exhibits the above-mentioned series of various operations at predetermined intervals.

〔Effect of the invention〕

According to the present invention, the toy body exhibits an action of walking forward for a predetermined period of time, and during this action, the first cam, the second cam, and the third cam are rotated in conjunction with the output gear of the interlocking switching mechanism, The second cam first rotates the tail body of the toy body from a downwardly inclined state to a backwardly upwardly inclined state, and then the first cam forcibly rotates the rear leg body via a link mechanism. Then, the toy body lifts the left and right front legs to make it sit down, and with this movement, the tail body with its tip touching the ground causes the toy toy body to move forward. The third cam slides the switching gear of the interlocking switching mechanism in the axial direction, switches the front leg drive mechanism, and moves the crank arms at both ends on different axes. The left and right front legs, which have been converted to the same axis and aligned at approximately the same height, are simultaneously moved up and down, and the vertical movement of the front legs also causes the left and right hind legs to move up and down. As a result, due to the interaction between the hind legs and the tail body for a predetermined period of time, the toy body lifts its front legs and moves up and down as a whole while standing up, exhibiting a chin-ching motion, and also exhibits a third movement. When the front leg drive mechanism is switched and interlocked by the cam via the interlock switching mechanism, the head back and forth movement mechanism is interlocked when the toy is in a seated state, and the head body is moved back and forth,
The toy body moves up and down in a bouncy manner and exhibits a chin-chin motion.This motion is always driven in a fixed direction without requiring the forward and reverse rotation of the power source or the forward and reverse rotation of gears, and does not cause strain on each mechanism. No load is applied,
It is very interesting because it makes little noise and clearly exhibits the walking and sitting movements of animals such as dogs.
