Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a toy drive mechanism having a very simple structure that is molded from an extremely lightweight material such as plastic and has a very simple structure that allows a toy to move by operating a movable part, and a toy using the drive mechanism.

[0002]

[Prior art]

 Conventionally, cheap Zenmai is often used as a drive source for moving lightweight toys in order to reduce manufacturing costs. By the way, the movement of moving parts in moving lightweight toys is not limited to rotational movement, but various movements are often required. In order to obtain intermittent repetitive linear motion at high speed with a strong force, a technique is known in which the process of repeating the process of compressing and releasing the cylindrical coil spring with a combination of a spring and a cam is known.

[0003]

[Problems to be solved by the device]

 In the case of the coil spring as described above, the energy must be stored by the cam mechanism. In addition, due to the restrictions of lightweight toys, the mainspring must use a small one, so the cam mechanism required to control the release energy of the mainspring to contract and release the coil spring becomes more complicated. The energy loss was large and the duration was extremely short.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a mainspring mechanism that is wound in a case through a winding shaft that is supported by the case, and has a chevron tooth on a part of the outer periphery in association with the drive shaft of the mainspring mechanism. A drive gear having a drive gear is provided, 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 the drive lever is planted in the drive gear and the drive pin is driven. It is characterized in that it is fitted in a long groove formed at the rear portion of the 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 the appearance of a fish, a tail fin is connected to the speed control claw, a water gun having a nozzle as a mouth of a goldfish is formed in the case, and the drive lever is composed of an inner tube of the water gun. Is characterized by. 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]

[Action]

 Since the teeth of the drive gear have toothless portions, the rotational speed of the drive gear is not uniform. In other words, when the speed control pawl engages 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 reduced. It is transmitted directly to the drive gear via the pinion and rotates rapidly. Therefore, the reciprocating movement of the drive lever by the drive pin on the drive gear causes the goldfish to intermittently blow water out of its mouth while swimming, or land animals can jump while moving their arms.

【Example】

 An embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a side view of the entire 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-blowing goldfish is shown as the first embodiment. When the toy 10 is wrapped around the mainspring 1 and floated on the water, the water is intermittently ejected from the mouth into the air while swinging the tail fin 10c and swimming. In the figure, reference numeral 20 indicates a case of the toy body that houses the drive mechanism. Reference numeral 1 is a mainspring, the inner end of the mainspring 1 is connected to the winding shaft 2, the outer end is fixed to the inside of the mainspring case 20a, and the gear 3 is 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 the 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. A pinion 5 is fixed to the shaft 4 and meshes 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 that reciprocates in the horizontal direction. Then, as the drive gear 6 rotates, the drive lever 14 is reciprocated by the double dimension between the shaft 4 and the pin 7.

Reference numeral 10 c is a caudal fin of the toy 10, in which a pair of speed control claws 12 and 13 are alternately engaged with each of the angled teeth 8 of the drive gear 6, and the speed control claws 12 and 13 rotate 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 are kicked by the turning force from the mainspring 1, and the other speed controlling claw 13 (12) is used as a stopper. Engage with one of the other chevron teeth 8. Without the speed control claws 12 and 13, since there is no resistance even if the mainspring 1 is wound up, 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 rotational speed while braking in small increments.

The operation of this embodiment configured as described above will be described. When the speed control pawls 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 loosened. It moves linearly at a constant speed. However, since the drive gear 6 has the chevron teeth 8 only half its circumference, when the speed control claws 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, it is rapidly rotated, and the speed-adjusting pawls 12 and 13 are engaged with the next chevron-shaped tooth 8 to adjust the speed again. With the above structure, 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 action of the water gun inner cylinder 14 sucks in water in a gentle stroke and makes a rapid stroke. Then, you can get a water-blown goldfish that spouts water from the mouth into the air.

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. 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 incorporated in the case 20 has a mainspring and gears incorporated 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 rotary 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 rotary rod 53. The operating rods 54 provided on the upper portions of the speed adjusting claws 12 and 13 are inserted into the long grooves 55. Arms 51, 51 of the moving object are attached to both ends of the rotating rod 53. On the other hand, a pin 62 is horizontally extended at the lower part of the drive lever 14, and its tip is fixed to the upper part of the leg 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 claws 12 and 13 approach the toothless portion 9, the drive gear 6 rapidly rotates, the impact causes the leg portion 71 to strongly hit the ground, and the toy 50 jumps.
