DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference to FIGS. 1–6, a toy with a moving head has a seat (17) provided in a lower end thereof, a gearbox (11), a head (2), and a transparent sphere (1).
The seat (17) has a battery box (171) provided on a top end thereof, a switch (15) mounted adjacent to the battery box (171), a buzzer (21) and a speaker (20) abutting the battery box (171), and a circuit board (16) adjacent to the switch (15) and electrically connected to the battery box (171), the switch (15), the buzzer (21) and the speaker (20).
A front support (14) is provided in a front end of the seat (17), and a front slot (141) is transversely defined in the front support (14). A right support arm (142) and a left support arm (143) extend out of the two sides of the front support (14), respectively. Two circular grooves are defined respectively at the ends of the support arms (142, 143). A rear support (23) is provided in a rear end of the seat (17) and a rear slot (231) is transversely defined in the rear support (23).
With reference to FIGS. 1, 2, 3 and 5, the gear box (11) has a right shell (29) and a left shell (33). A first protrusion (111) is integrally formed at a front end of the gear box (11) and inserted into the front slot (141) and a second protrusion (112) is integrally formed at a rear end of the gear box (11) and inserted into the rear slot (231). A right sliding passage (291) is defined in an upper periphery of the right shell (29) and a left sliding passage (331) is defined in an upper periphery of the left shell (33) and corresponds to the right sliding passage (291). Two guide pegs are formed respectively inside the right and left sliding passages (291, 331).
A first motor (35) abuts the lower periphery of the right shell (29) and a series of gears, a series of axles and a series of tubes are interconnected and mounted in the gear box (11) and connected to the first motor (35). The series of the gears has a first gear (40), a second gear (39), a third gear (38), a fourth gear (37), and a fifth gear (31). The series of the axles comprises a first axle (41), a second axle (36) and a third axle (30). The series of the tubes comprises a first tube (32) and a second tube (34). A first end of the first tube (32) extends out of the right shell (29) to be connected to an upper right actuating wheel (10) and a second end of the first tube (32) extends out of the left shell (33) to be connected to an upper left actuating wheel (26). An upper right eccentric lug (101) is formed eccentrically on the upper right actuating wheel (10) and an upper left eccentric lug (261) is eccentrically formed on the upper left actuating wheel (26).
A first end of the second tube (34) extends out of the right shell (29) to be connected to a lower right actuating wheel (12), and a second end of the second tube (34) extends out of the left shell (33) to be connected to a lower left actuating wheel (24). A lower right skewed lug (121) is formed eccentrically on the lower right actuating wheel (12) and a lower left skewed lug (241) is formed eccentrically on the lower left actuating wheel (24). The lower right and left skewed lugs (121, 241) are inserted into and pivoted relative to the circular grooves in the right and left support arms (142, 143) of the front support (14), and two end plates (13) are mounted at the ends of the support arms (142, 143) to hold the skewed lugs (121, 241) in the grooves.
A drive pulley (42) abuts the periphery of the left shell (33) and is connected to the first motor (35) via a central axle of the first motor (35). The first axle (41) is rotatably mounted in the left shell (33). A transfer pulley (44) abuts the periphery of the left shell (33) and is connected to a first end of the first axle (41). A drive belt (43) connects the drive pulley (42) to the transfer pulley (44). A second end of the first axle (41) is inserted into the left shell (33) and the first gear (40) is inserted onto the second end of the first axle (41). The second axle (36) is provided in the gear box (11) and the second gear (39) is rotatably mounted on the second axle (36). The third axle (30) is provided in the gear box (11) and the third gear (38) is rotatably mounted on the third axle (30). The fourth gear (37) is mounted on the second tube (34) and the fifth gear (31) is mounted on the first tube (32). Hence, all the gears are interconnected to each other and rotate simultaneously when driven by the first motor (35).
A right sliding plate (9) is received into the right sliding passage (291) and a left sliding plate (27) is received into the left sliding passage (331). A right horizontal slot (91) is transversely defined in the right sliding plate (9) and receives the upper right eccentric lug (101). A left horizontal slot (271) is transversely defined in the left sliding plate (27) and receives with the upper left eccentric lug (261). A right vertical slot (92) is defined in the right sliding plate (9) and a left vertical slot (272) is defined in the left sliding plate (27). The right and left sliding plates (9, 27) are mounted such that the guide pegs in the sliding passages (291, 331) are received in the right and left vertical slots (92, 272). A right cover (8) and a left cover (25) are mounted over the sliding passages (291, 331) to hold the sliding plates (9, 27) within the sliding passages (291, 331).
The head (2) has a chamber defined in an interior thereof and a second motor (3) is provided in the chamber. A lever (6) is connected to a rod (51), which is pivotally mounted to an inner wall of the chamber. Hence, the lever (6) can pivot relative to the chamber. A spring (5) is connected to the rod (51) and the free end of the lever (6) is connected to an end of a tether (4). The other end of the tether (4) is attached to the axle of the second motor (3). A jaw (7) is connected at the two ends of the rod (51). The battery box (171) is covered with a battery cap (18). The mechanical elements of the present invention are covered with a cloth (28), except for the head (2), thereby hiding the gearbox.
With reference to FIGS. 1, 3, 6 and 7, when the second motor (3) operates, the tether (4) is drawn up and to wind around the axle of the second motor (3) thereby pivotally the lever (6). This in turn rotates the rod (51) causing the jaw (7) to open. When the second motor (3) stops, the resilient force of the spring (5) forces the tether (4) to unwind from the axle of the second motor (3), returning the jaw (7) to its original closed position. With the alternating operation of the second motor (3), the jaw (7) can be alternately opened and closed. The series of the gears are rotated by the first motor (35). The upper actuating wheels (10, 26) are rotated by the first tube (32) to reciprocate the sliding plates (9, 27), thereby causing the head (2) to alternately rise and fall.
The transparent sphere (1) has an open end defined in a lower end thereof and the open end is mounted around a periphery of the seat (17). A collar (19) is provided on the periphery of the seat (17) to position the transparent sphere (1) on the seat (17).
Furthermore, with the rotation of the lower actuating wheels (12, 24) driven by the second tube (34), the gear box (11) can swivel between the front support (14) and the rear support (23). In addition to the foresaid action, the speaker (20) and the buzzer (21) are added to present a lived and dynamic effect of the present invention.
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
