BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drive mechanism for a toy and a drive mechanism for the toy, which is molded from an extremely lightweight material such as plastic and has a very simple structure that allows a movable part to be operated by power to move. Related to toys.

[0002]

2. Description of the Related Art Conventionally, an inexpensive spring is often used as a drive source for a moving lightweight toy in order to reduce the manufacturing cost. By the way, movement of a movable part in a moving lightweight toy is not limited to rotational movement, and various movements are often required. In order to obtain intermittent repetitive linear motion at a high speed with a strong force, there is known a technique of repeating a process of compressing and releasing a cylindrical coil spring with a combination of a spring and a cam.

[0003]

In the case of the coil spring as described above, the cam mechanism must store energy. Moreover, because of the restrictions of lightweight toys, a small spring must be used, so the cam mechanism required to control the release energy of the mainspring to contract and release the coil spring becomes more complicated. The loss was large and the duration was extremely short.

[0004]

In order to solve the above problems, the present invention provides a mainspring mechanism that is wound up through a winding shaft pivotally supported by the case in the case, and is interlocked with the drive shaft of the mainspring mechanism. Then, a drive gear having chevron teeth is provided on a part of the outer circumference, and a speed control pawl for controlling the rotational movement of the drive gear is attached to the case, while a drive pin for driving a drive lever is planted in the drive gear. In addition, the drive pin is fitted in a long groove formed in the rear portion of the drive lever, and the drive lever is moved back and forth by the rotational movement of the drive pin. In addition, the case is made to have a fish appearance, and a tail fin is connected to the speed control claw, and a water gun having a nozzle as a mouth of a goldfish is formed in the case,
It is characterized in that the drive lever is composed of an inner cylinder of a water gun. Further, the case is made to have the appearance of a land animal, and the arm portion is connected to the speed control claw, and the leg portion is connected to the drive lever.

[0005]

Since the teeth of the drive gear have toothless portions, the rotation speed of the drive gear is not uniform. That is, when the speed control pawl is engaged with the teeth of the drive gear, the rotation is relatively gentle, and when the speed control pawl approaches the toothless portion, the drive gear loses control resistance and the spring release force is released. It is transmitted directly to the drive gear via and rotates rapidly. Therefore, due to the reciprocating movement of the drive lever by the drive pin on the drive gear, the goldfish intermittently blows water from the mouth while swimming, or the land animal jumps while moving its arm.

[0006]

Embodiments of the present invention will be described in detail with reference to the drawings. 1 is an overall side view of the first embodiment, FIG. 2 is a plan view with an upper exterior removed, FIG. 3 is a plan view showing the principle of the present invention, and FIG. 4 is a side view of FIG. The present invention is, as it were, a toy that moves by utilizing pulsation, and a water-blown goldfish is shown as the first embodiment. When the toy 10 is wound around the mainspring 1 and floated on the water, the water is intermittently ejected from the mouth into the air while swimming by shaking the tail fin 10c. In the figure, reference numeral 20 indicates a case of the toy body that houses the drive mechanism. Reference numeral 1 is a mainspring, and the inner end of the mainspring 1 is a winding shaft 2.
The outer end is fixed to the inside of the mainspring case 20a, and the gear 3 is further connected to the upper part. A stopper works so that the winding shaft 2 rotates in one direction with respect to the case 20, and when the winding shaft 2 is wound up, the mainspring 1 is wound, and a rotating force is applied to the gear 3 with the winding shaft 2 as a reference.

Reference numeral 6 is a drive gear having a plurality of chevron teeth 8 formed on about half of its outer circumference, and the remaining portion is a drive gear having a toothless portion 9 lacking chevron teeth. It is rotatably supported in a cantilever manner. The shaft 4 has a pinion 5
Are fixed and mesh with the gear 3. Therefore,
The drive gear 6 is rotated by the force of the mainspring 1.

A drive pin 7 is planted on the upper surface of the drive gear 6, and is fitted in a long groove 15 provided in a drive lever 14 which reciprocates in the horizontal direction. Then, as the drive gear 6 rotates, the drive lever 1 is moved by a size twice that between the shaft 4 and the pin 7.
Move 4 back and forth.

Reference numeral 10c is a caudal fin of the toy 10. A pair of speed control claws 12 and 13 are alternately engaged with each of the chevron teeth 8 of the drive gear 6, and the speed control claws 12 and 13 are arranged around the shaft 11. It reciprocates in a small angle in the direction of the arrow. The shape of the tooth 8 and the speed controlling claws 12, 13 and the speed controlling claw 12 (13) engaged with the tooth 8 is kicked by the turning force from the mainspring 1, and the other speed controlling claw 13 (12) is used as a stopper. To engage one of the chevron teeth 8. Without the speed control claws 12 and 13, even if the mainspring 1 is wound up, there is no resistance, so the drive gear 6 rotates at once and the energy of the mainspring is released instantaneously. However, in the present embodiment, the speed control claw 12 is used. By the action of Nos. 13 and 13, it is possible to obtain a substantially constant rotation speed while applying the brake in small increments.

The operation of the present embodiment configured as described above will be described. When the speed control claws 12 and 13 are engaged with the chevron teeth 8 of the drive gear 6, the drive gear 6 rotates at a constant controlled speed, so that the water gun inner cylinder 14 via the pin 7 is gently constant. Move linearly at speed. However, since the drive gear 6 has the chevron teeth 8 only half its circumference, when the speed control pawls 12 and 13 reach the toothless portion 9, the function as the speed governor is lost only in that section, and the drive gear 6 is controlled. Then, the speed control claws 12, 13 are engaged with the next chevron tooth 8, and the speed is controlled again. With the above configuration, when the mainspring 1 is now rolled up by hand and released to the surface of the water, the goldfish is propelled by the tilt of the caudal fin 10c and moves forward, and at the same time, the water gun inner cylinder 1
By the action of 4, a water-blowing goldfish is obtained in which water is inhaled in a gentle stroke and water is ejected from the mouth into the air in a rapid stroke.

A second embodiment of the present invention is shown in FIGS. 5 to 7. FIG. 5 is a front sectional view of the second embodiment, FIG. 6 is a side sectional view, and FIG. 7 is a movement of an arm. FIG.
In the figure, reference numeral 20 indicates a case of the toy body that houses the drive mechanism. As in the first embodiment, the mainspring case 20a built in the case 20 has a mainspring and gears built therein. Further, the drive gear 6, the drive pin 7, and the elements having the same configurations and functions as those of the first embodiment are designated by the same reference numerals.

A rotating rod 53 is horizontally rotatably attached to the inside of the case 20 by a shaft 57. A long groove 55 is formed at one end of the rotating rod 53. Into the long groove 55, the operating rod 54 provided on the upper portions of the speed control claws 12 and 13 is inserted.
Animal arm portions 51, 51 are attached to both ends of the rotating rod 53. On the other hand, a pin 62 is horizontally extended to the lower portion of the drive lever 14, and its tip is fixed to the upper portion of the leg portion 71.

The operation of the present embodiment configured as described above will be described. When the speed control claws 12 and 13 are engaged with the chevron teeth 8 of the drive gear 6, the operating rod 54 swings, so that the rotating rod 53 horizontally rotates about the shaft 57. However, when the speed control pawls 12 and 13 reach the toothless portion 9, the drive gear 6 rapidly rotates, and the impact causes the leg portion 71 to strongly hit the ground,
The toy 50 jumps.

[0014]

[Effect] Since the drive mechanism of the present invention effectively controls the release energy of the mainspring with the small size and simple structure as described above, a constant pulsating stroke can be efficiently generated. In addition, the energy loss of the mainspring is eliminated and the duration is extremely long. Therefore, it is extremely effective for various moving toys, such as a water-blowing goldfish and a jumping kangaroo toy, and it cannot be enjoyed as a toy for a long time.
