Description

[Detailed description of the invention] This invention relates to an active animal toy, in which the toy has an external shape similar to that of a small dog, and by the operation of an automatic gear switching mechanism, it alternately and continuously performs walking and sitting actions, and also performs sitting actions. The purpose of this invention was to provide an animal toy that, when the toy's front legs are aligned and the toy's upper body jumps up, presents an adorable state that resembles a small dog begging for something.

This will be explained based on the embodiment shown in the drawings.
Reference numeral 1 denotes a toy body shaped like a small dog, with a battery box 2 sandwiched inside and a front machine frame 3 and a rear machine frame 4 formed before and after the battery box 2. The nose gear 5 is attached to both sides of a support shaft 6 supported on the front frame 3 by inserting vertical holes 7, 7 formed at the upper end of the support shaft 6, respectively. 8
is a crankshaft attached below the support shaft 6 supported on the front machine frame 3, and one of the protruding ends protruding outward from the machine frame is formed on a crank 9, and one of the front legs 5a is rotatably supported by the crankshaft. , the other protruding end is near its tip.
The connecting plate 11 with the engaging parts 10, 10 formed at 180° positions is fixed, and an engaging pin 12 that engages with the engaging parts 10, 10 is fixed on the inner side of the outer side 8a. A rotating plate 14 on which a crank pin 13 is fixedly attached is loosely attached to the outer surface of the plate, and the other front leg 5b is rotatably supported on the crank pin 13. 15, 15 each have one end attached to the front leg 5
a and 5b, and a crank part 17 formed on both protruding ends of a crank-shaped support shaft 16 whose other end is supported on the rear machine frame 4. , 17, and are pivotally attached to the upper ends of rear legs 18a and 18b, which are rotatably supported by the rear legs 18a and 17. The rear legs 18a and 18b each have a traction spring 19 that is hooked at one end to the upper rear part of the rear machine frame 4 and hooked at the other end to the cranks 17, 17, respectively.
19 so that the rotating position is always ensured. That is, when the rear legs 18a, 18b are rotated about the support shaft 16, the pivot support in the rear machine frame 4 of the support shaft 16 is located on either the left or right side of the traction springs 19, 19. Sama traction spring 19, 19
The rear legs 18a and 18b are moderated by attaching the following.

Reference numeral 20 denotes a swinging rod whose base end is attached to the crank part 17 which pivotally supports the rear leg 18b.A horizontally elongated hole 21 is formed in the front end of the swinging rod. ing. Reference numeral 23 denotes a clutch plate which is rotatably pivoted on the swinging rod 20, and has a cross-section shaped like a square, and near the tip thereof, an engaging pawl 25 on the rotating disk 24 fixed on the shaft 22 is attached. A notch 26 that engages only during reverse rotation is formed downward, and the other end of a spring 54, which has one end hooked to a locking protrusion 20a provided on the swinging rod 20, is hooked to the rear end. Thus, the distal end of the clutch plate 23 is always in contact with the rotating disk 24, so that the engagement between the notch 26 and the engagement pawl 25 becomes even more reliable.

Reference numeral 27 denotes a switching gear which is an automatic gear changing device installed on the sliding shaft 28 inside the front machine frame 3, and is connected to the prime mover 53.
It rotates in mesh with the associated drive gear. This switching gear 27 is a fixed gear 2 fixed on a sliding shaft 28.
9 and a free gear 30, of both gears, the fixed gear 29 has fewer teeth than the free gear 30, and the idle gear 30 is provided with an engagement hole provided in the fixed gear 29. It has the same structure as a conventionally known automatic gear changing mechanism for this type of gear.

Reference numeral 32 denotes a reversing gear fixed on the sliding shaft 28, and as the sliding shaft 28 slides due to the action of the automatic gear switching mechanism, the first meshing gear 3 on the intermediate shaft 33
4 or the second meshing gear 36 on the intermediate shaft 35. 37 is an intermediate gear fixed on the intermediate shaft 35, and is formed so as to always mesh with the first meshing gear 34 and mesh with the gear 39 on the crankshaft 8 to which the pinion 38 is fixed and the front leg 5 is attached. are doing. Reference numeral 40 denotes an intermediate gear fixed on the intermediate shaft 33 to which the first meshing gear 34 is fixed, and is formed so as to mesh with the gear 41 on the shaft 22 fixed to the outer end of the rotating disk 24.

Reference numeral 42 denotes a crank formed on the protruding end of the intermediate shaft 33 that protrudes outward from the front machine frame 3, and a connecting rod 45 whose one end is connected to a crank 44 which forms a tail 43 and is mounted on the rear machine frame 4. The other end is connected. Reference numeral 46 denotes an interlocking rod whose one end is connected to a whistle 49 which is installed in a head body 48 that is rotatably pivoted to the toy body 1, and has a locking step 50 on one side of the other end. A connecting hole 51 is formed, and the crank 42 is inserted through and connected to this connecting hole 51. 52 is a spring connected to the interlocking rod 46;
The device is designed to have the effect of opening and closing the mouth of the toy body by interaction with the toy body.

Since the present invention has the above structure, the switching gear 27
When the prime mover 53 is activated when the toy is in the state shown in FIG. 5, the toy body 1 starts walking in the state shown in FIG. 1 in the same way as a normal walking animal toy of this kind. Next, when the switching gear 32 slides under the action of the switching gear 27 and meshes with the second meshing gear 36, the gear transmission between the crankshaft 8 and the shaft 22 changes, so that both rotate in opposite directions. Therefore, the rotating disk 24
2 starts to rotate in the opposite direction, the engaging pawl 25 engages with the notch 26 of the clutch plate 23, and the swinging rod 20 is moved forward of the toy body 1 via the clutch plate 23. Therefore, the rear legs 18a, 18b
The toy body 1 is also rotated forward about the support shaft 16, and the toy body 1 operates in a sitting position as shown in FIG. At this time, since the crankshaft 8 also begins to rotate in the opposite direction at the same time, the positions of the connecting plate 11 and rotating plate 14 are displaced, and the crank part 9 and crank pin 13 form a crankshaft bent in the same direction. . Therefore, front leg 5
a and 5b are aligned and rotated in the same direction at the same time. At this time, since the crank 42 of the intermediate shaft 33 also rotates in the opposite direction, the crank 42 engages with the locking step 50 in the connecting hole 15 of the interlocking rod 46, and moves the interlocking rod 46 downward. The head body 48 is rotated about the pivot 47 at the same time as the toy body is pulled down and a whistling sound is generated, thereby opening and closing the mouth of the toy body.

From the above, according to the present proposal, the toy body intermittently repeats the walking action and the jumping action from a bent down position due to the action of the automatic gear change mechanism.
During the jumping operation, the spindle that operates the front legs rotates one of them from the middle and aligns both front legs to the same position before operating, so after being connected to the aligned front legs by a connecting rod. It makes a standing motion with its legs together, and then makes a jumping motion with its hind legs raising its upper body, making it look like a small dog jumping up and down begging for something, which is extremely interesting. It is something.
