Description

WALKING TOY ANIMAL: BACKGROUND OF THE INVENTION: In animal kingdom, some are invertebrate and do not have any foot such as worm-lizard and worm-snake, some are two-footed such as human being and poultry, and some are quadruped such as alligator and saurians. Among the animals, quadruped animals are the ones of which conventional toy animal manufacturers most preferably wish to manufacture imitation. However, it is very difficult to drive the four legs of a toy animal to simulate a living animal to walk.
In regular walking toy animals, the moving of the legs of a toy animal is generally performed through rolling contact, i.e. rollers are mounted on the legs of a toy animal at the bottom to help a toy animal to move. Toy animals of roller type moving structure are very dull and monotonous and can not attract children to buy.
In non-roller type walking toy animals, either two-footed or four-footed, the legs must be driven to rotate up and down through a certain range of angle so as to efficiently rub against ground surface and to push the body to move ahead. In order to simulate the walking of a living animal, the front, back, left and right legs must be scheduled to rotate according to a proper sequence. In case the legs of a toy animal are driven to rotate synchronously, the toy animal will be unable to move forward.
It is therefore, the main object of the present invention to provide such a walking toy animal which utilizes a gear power transmission mechanism, a pair of eccentric pins and a pair of driving axles to drive the four legs of the toy animal to rotate through a curved angle in proper sequence so as to simulate the walking of a quadruped animal.
Another object of the present invention is to provide such a walking toy animal which includes a selector switch to control the the toy animal to stop operation, to operate continuously or to operate intermittently according to the instruction of a pickup which will be triggered by external sound source.
Still another object of the present invention is to provide such a walking toy animal which includes a music IC and a speaker to simulate the crying of an animal.
A yet further object of the present invention is to provide such a walking toy animal which includes a safety ratchet to automatically cut off power transmission to let motor rotate idly when the power transmission mechanism is stuck, so as to protect the structure from damage.
SUMMARY OF THE INVENTION: The present invention relates to a walking toy animal which can be alternatively controlled through a selector switch to continuously generate sound, swing the head, and rotate the legs, or intermittently operated through the control of external sound source, in which gear set, eccentric wheels, eccentric pins and driving axles form a power transmission mechanism to drive the head and the legs of the toy animal to move.
BRIEF DESCRIPTION OF THE DRAWINGS: Fig. 1 is a perspective schematic view of a walking toy animal constructed according to the present invention; Fig. 2 is a perspective schematic view illustrating the internal structure of the present invention; Fig. 3 is a perspective fragmentary view of the present invention, illustrating the structure of the power transmission mechanism; Fig. 4 is a schematic drawing illustrating the continuous motion of the legs of a walking toy animal according to the present invention; and Fig. 5 is a schematic drawing illustrating the connection of the head portion with the upper shell and the bottom shell.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS: Turning now to the annexed drawings in detail, therein illustrated is a walking toy animal embodying the present invention and generally comprised of an upper shell (1), a bottom shell (2), two front legs (21) (21'), two back legs (22) (22'), a head portion (3), and a power transmission mechanism. There are mounted in the bottom shell (2) a battery chamber (23), a circuit board (24) and a gear box (25). As illustrated, a motor (251) is received in the gear box and comprising a motor shaft (252) having mounted thereon a pinion (253). The pinion (253) is engaged with a gear (2541) on an axle (254) at one end. The axle (254) comprises another gear (2542) at the other end. The gear (2542) is engaged with a gear (2551) on another axle (255).
The axle (255) comprises a pinion (2553) enga'ged with a gear (2561) on another axle (256). A ratchet (2552) is co-axially connected with the gear (2553) on the axle (255). When the legs of the toy animal are stuck, the ratchet (2552) will immediately drive the gear (2553) to move away therefrom to cut off power transmission. As soon as resistance is disappeared, the spring (2554) which is mounted on the axle (255) will drive the gear (2553) back to engage with the ratchet (2552). Another axle (256) is set in the gear box and comprises an intermediate gear (2562) engaged with a big gear wheel (261) on a main axle (26). Two eccentric wheels (262) and (263) are mounted on the main axle (26) respectively disposed in contact with two push rods (264) and (265). The two push rods (264) and (265) are disposed to bilaterally connect with the head portion (3).Two rollers (266) and (267) which comprise respectively an eccentric axle (26681) or (26691) are mounted on the main axle (26) at both ends and respectively supported by two bearing brackets (2668) and (2669). The two front legs (21) and (21') are respectively inserted through holes (213) (213') of the bottom shell (2) letting the eccentric axles (26681) and (26691) respectively insert into the holes (211) (211') of the two front legs (21) and (21'). The two back legs (22) and (22') are respectively inserted through holes (214) and (214') of the bottom shell (2) and further connected with two pins (224) and (224') which are respectively inserted through the axial holes (221) and (221') of the back legs (22) and (22') to become firmly positioned at two bearing brackets (215) and (215').
The back leg (22) or (22') includes a upper connection end (225) or (225') having a recess (222) or (222') made thereon with an unitary pin (223) or (223') raised therefrom. Two driving axles (226) and (226') are bilaterally set inside the bottom shell (2) and respectively connected with the two front legs (21) and (21') and the two back legs (22) and (22'). As illustrated, each driving axle (226) or (226') comprises two holes (2261 and 2262) or (2261' and 2262') for insertion therein of the pin (212) or (212') and the pin (223) or (223') respectively.
Through pin-and-eye connection, the two front legs (21, 21') and the two back legs (22, 22') are respectively coupled with the two driving axles (226, 226').
The gear box (25) is covered with a box cover (2555) to let the axles (254), (255) and (256) be firmly positioned therein. A bearing block (26) each is respectively mounted on the bearing brackets (2668) and (2669) at the top to let the eccentric axles (26681) and (26691) be firmly positioned therein. The bearing brackets (215) and (215') are also respectively covered with a bearing block (217).
The upper shell (1) comprises a pair of housings (11) and (11) bilaterally disposed at the front two corners to define the moving range of the upper ends of the two front legs (21) and (21'), and another pair of housings (12) and (12') bilaterally disposed at the rear two corners to define the moving range of the upper ends of the two back legs (22) and (22').
As illustrated in Fig. 5, the head portion (3) comprises an axial hole (31) for insertion therein of the unitary pin (13) of the upper shell (1) from the top and the unitary pin (222) of the bottom shell (2) from the bottom. Through tenon-and-groove connection, the head portion (3) is firmly connected to the body of the toy animal. In the annexed drawing, the numeral (4) designates a circuit board, and the numeral (41) designates a pickup.
When motor starts to rotate, the main axle (26) drives the eccentric wheels (262) and (263) to push the push rods (264) and (265) to further drive the head portion (3) to swing. At the same time, the eccentric axles (26681) and (26691) of the rollers (266) and (267) drive the two front legs (21) and (21') to rotate up and down through a curved angle.
By means of power transmission through the driving axles (226) and (226'), the two back legs (22) and (22') will be carried to rotate up and down through same curved angle. The rotation of the left back leg (22') is in conformity with the right front leg (21) and the right back leg (22) is in conformity with the left front leg (21'). Fig. 4 illustrates the continuous rotary motion of the legs. When the front leg (21) is going to lift from the ground, the back leg (22) is about to rub on the ground (see Fig. 4-A); when the front leg (21) is lifted from the ground to step ahead, the back leg (22) starts to rub on the ground (see Fig. 4-B); when the front leg illustrated in Fig. 4-B. When the front leg (21) is stepping on the ground to start rubbing, the back leg is about to lift from the ground (see Fig. 4-C).
One of the main features of the present invention is the use of the rollers (266) and (267) which protect the main axle (26) from pressure and torsional force.
