DETAILED DESCRIPTION

In the following paragraphs, some embodiments of the invention will be described by way of example and not limitation. It should be understood based on this disclosure that various other modifications can be made by those in the art based on these illustrated embodiments.
Hereinafter, embodiments of a form changing toy according to the present invention will be described based on embodiments shown in the drawings. In the present specification and the scope of claims, a switch is a part of the movable part to perform moving.
As shown in FIGS. 1 and 2, the form changing toy 1 includes components of a body part 2, leg parts 3, a head part 4, a horn part 5, a tail part 6, etc. In the state shown in FIG. 1, the leg parts 3 are operated by a power source, and the form changing toy 1 moves forward while the head part 4 is continuously inclined downwardly. Then, at the point after a predetermined number of steps which the form changing to 1 takes, the horn part 5 projects forward, and when the head part 4 reaches the lower end, as shown in FIG. 2, an upper jaw 4 a, which is a part of the head part 4, swings vertically, so that while the horn part 4 swings vertically and the upper jaw 4 a swings vertically, it moves forward.
As shown in FIG. 1, the leg parts 3 are constituted with right and left front legs 3 a, and right and left back legs 3 b. As shown in FIG. 3, in the right and left front legs 3 a, the middle part is rotatably supported by an eccentric shaft 11 of a power system 10, and the upper end part is rotatably supported by the shaft 2 a, which is secured to the body part 2 through an elongated hole 3. On the other hand, in the right and left back legs 3 b, the middle part is rotatably supported to the body part 2 by a shaft 3 d. The middle part of the right and left front legs 3 a and the upper part of the right and left back legs 3 b are connected each other by a connecting body 7.
In the leg parts 3, the front legs 3 a swing by the eccentric shaft 11 which rotates by the power. The movement of the front legs 3 a is transmitted to the upper part of the back legs 3 b through the connecting body 7, and the back legs 3 a swing around the shaft 3 d as a center. In this case, when the front leg 3 a swings forward, the back leg 3 b swings rearward.
In the left and right sides of the form changing toy 1, the left and right eccentric shafts 11 are positioned with 180 degree phase difference each other. With this structure, when the left front leg 3 a swings forward, the right front leg 3 a swing rearward. By repeating this movement, the form changing toy 1 moves forward.
As shown in FIG. 4, the head part 4 is supported by the body part 2 through a connecting body 8. The connecting body 8 has an approximately triangular shape, and one corner part is rotatably arranged to the body part 2 by the shaft 2 a, and in the inside of the other one corner part, an elongated hole (not shown) is formed. In the elongated hole, a shaft 2 b is inserted and is rotatably supported by a slider 21 which will be described later. In the other remaining corner part of the connecting body 8, a lower jaw 4 b which is part of the head part 4 is formed.
The head part 4 is continuously lowered by a head part operation mechanism 20. As shown in FIG. 3, the head part operation mechanism 20 is provided with the slider 21 which is positioned in the upper side of the connecting body 7. The slider 21 is operated in the front and back direction. On the lower part of the slider 21, a serrated ratchet tooth 21 a is formed. On the other hand, a ratchet claw 7 a is formed on the connecting body 7. On the one side of the slider 21, as mentioned above, the connecting body 8 is rotatably supported by the shaft 2 b.
As shown in FIGS. 5 and 6, the slider 21 is formed over both sides of the body part 2, and on a plate 21 b which is the part over both sides of the body part 2, an elongated hole 21 c is formed and an elastic piece 21 d is formed in a projecting manner in the elongated hole 21 c. On the other hand, on the upper surface of the body part 2, a projection part 2 c is formed. On the side surface of the projection part 2 c, a plurality of recess parts 2 d is formed. The slider 21 is arranged in the body part 2 by fitting the elongated hole 21 c to the projection part 2 c of the body part 2, and the top end of the elastic piece 21 d presses and contacts to the recess parts 2 d of the projection part 2 c.
According to the head part operation mechanism 20 with such configuration, the ratchet claw 7 a contacts to the ratchet tooth 21 a of the slider 21 in accordance with the operation of the connecting body 7, and the slider 21 moves forward by an amount of one tooth only. Then the connecting body 8 is rotated around the shaft 2 a through the shaft 2 b, and the head part 3 is lowered by the amount of one tooth. The top end of the elastic piece 21 d is fitted to the next recess part 2 d, and the position of the slider 21 is determined. By repeating such operation, the head part 4 continuously moves downward. When the head part 4 reaches the lowest point, the top end 7 b of the connecting body 7 enters in the moving area and the upper jaw 4 a is pushed upward by the top end 7 b of the connecting body 7. When the top end 7 b of the connecting body 7 is retreated, in accordance with that, the upper jaw 4 a is lowered by its own weight so as to close the mouth.
Further, in the form changing toy 1, a unit case 50 is detachably mounted to the body part 2. The unit case 50 is provided with a horn locking mechanism 30 which locks a horn 50 a in the back side in a laying manner.
In the unit case 50, as shown in FIG. 6, the base part of the horn 5 a is rotatably supported to the bracket 2 e projecting to the unit case 50. The horn 5 a is urged by spring (not shown) so as to rotate toward the front side. The horn 5 a is locked by a hook 31, which is provided in the unit case 50, and is restrained to the body part 2. The hook 31 is urged in a locking direction by the spring, and the lower end part is stored in a hole 21 e which is formed on the slider 21. When the slider 21 moves forward, the lower part of the hook 31 is rotated by a rear end wall (not shown) of the hole 21 e, and therefore, the hook 31 becomes a release state.
Further, the form changing toy 1 is provided with an operation mechanism 40 in which the horn 5 a swings in a vertical direction in a state of projecting the horn 5 a forward as shown in FIG. 2. The operation mechanism 40 is provided with a slide body 41 which slides in a front and back direction by the gear of the power system 10 which will be described later.
As shown in FIG. 9, on the upper front end of the slide body 41, a projection 42 is formed. The projection 42 responses to the rear end 5 b of the horn 5 a. In a state in which the slide body 41 slides forward, the projection 42 contacts to the rear end 5 b of the horn 5 a, so that the top end of the horn 5 a moves upward.
The movement of the slide body 41 in the front and back direction is performed by the gear of the power system 10. As shown in FIG. 8, in the power system 10, the large gear 12 a is rotated by a motor (not shown), and a small gear (not shown) fastened in the same shaft meshes with a large gear 13 a. The large gear 13 a meshes with a crown gear 14 a. In the crown gear 14 a, a small gear 14 b is provided. On the other hand, an input gear 51 is rotatably supported in the unit case 50, and a gear 52 which meshes with the input gear 51 is rotatably supported.
When the unit case 50 is set to the body part 2, the input gear 51 meshes with the gear 14 b of the body part 2.
The gear 52 is stored inside the unit case 50. A pin 52 a is disposed in the upper surface of the gear 52. On the other hand, in the slide body 41, a cam (not shown) is formed. The slide body 41 moves in the front and back direction by the revolution of the pin 52 a in accordance with the rotation of the gear 52. When the slide body 41 moves forward, the projection 42 contacts to the rear end 5 b of the horn 5 a.
In the power system 10, the large gear 13 a and the small gear 13 b on the same shaft mesh with a crank gear 15 a. The power is transmitted to the crank shaft. With this structure, the front legs 3 a are operated.
In the form changing toy 1, the ratchet claw 7 a is operated by the movement of the connecting body 7 which operates the legs 3, and therefore, the slider 21 moves forward. When the slider 21 moves a few pitches, the hook 31 is operated by the rear end of the hole 21 e which is formed in the plate 21 b, and the restraint of the horn 5 a releases. Then, the horn 5 a rotates forward by the urging force of the spring. During the period, the leg parts 3 are continuously operated by the power.
After that, the horn 5 a is operated by the projection 42 of the slide body 41 which is operated by the revolution of the pin 62 a of the gear 52. In the operation state of the horn 5 a at that time, depending on the shape of the cam formed in the slide body 41, it can be set in various operation modes such that for example, the horn 5 a gradually moves upward and moves down sharply, etc.
During walking of the form changing toy 1, the slider 21 intermittently moves forward, and the connecting body 8 is intermittently rotated through the shaft 2 b. That is, the head part 4 intermittently moves downward. Further, when the head part 4 reaches the lower end, since the top end 7 a of the connecting body 7 hits the base end of the upper jaw 4 a of the head part 4, the upper jaw 4 a rotates upward, and therefore, it opens with respect to the lower jaw 4 b.
In the form changing toy 1 of the aforementioned embodiment, the leg parts 3 always walk, and the head part 4 is continuously lowered from the beginning of the walk. The horn 5 a is deployed forward when it walks few steps, and next, the horn 5 a keeps swinging vertically. When the head part 4 reaches the lowest point, the mouth of the head part 4 opens and closes. After that, the horn 5 a moves vertically, it keeps walking while opening and closing the mouth of the head part 4. However, the timing of these operations can be changed appropriately. For example, the deploying timing of the horn 5 a can be changed by changing the interval between the rear end wall 21 f of the hole 21 e and the hook 31. By changing the shape of the cam which is engaged with the pin of the gear 52, the swinging mode of the horn 5 a can be changed.
In the aforementioned embodiment, as the component parts, the horn 5 a, the head part 4, and the upper jaw 4 a were shown, but other component parts can be employed.
In the aforementioned embodiment, the unit case 50 which is provided with the horn part 5 is mounted on the body part 2, but the unit case 50 which is provided with other component parts can be mounted.
