Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a toy drive mechanism equipped with two mainspring drive mechanisms, and when the mainspring is wound into the first mainspring mechanism, the second mainspring is automatically activated. The present invention relates to a drive mechanism for a toy in which a spring is also wound around the mechanism, and when the spring mechanism is unwound, the first and second spring mechanisms are unwound alternately to enable different operations.

[Prior Art] A traveling toy equipped with two drive mechanisms is disclosed in Japanese Utility Model Application No. 59-38997.
That is, it is equipped with a winch wrapped around a string and a first drive mechanism with a mainspring attached to the shaft. By pulling out the string, driving force is stored in the first drive mechanism, and as the first drive mechanism is released, the first drive mechanism is The rope is wound around the winch, and a flywheel that constitutes a second drive mechanism linked by a transmission gear rotates. Then, when the first drive mechanism is disengaged, the switching mechanism is activated, and the traveling body is driven by the flywheel of the second drive mechanism that rotates at high speed.

[Problems to be Solved by the Invention] The above conventional technology uses a mainspring for the first drive mechanism, and uses a flywheel rotated by the mainspring of the first drive mechanism for the second drive mechanism. Furthermore, since most of the driving force of the first drive mechanism during disengagement is used to rotate the flywheel of the second drive mechanism, it has been difficult to operate other operating members. Further, although the flywheel of the second drive mechanism is suitable for use as a driving force for driving the traveling body, it is not suitable for operating other operating members.

[Means for Solving the Problems] The present invention aims to solve the problems in the conventional technology described above, and a first spring mechanism and a second spring mechanism are disposed in the machine frame, and the first spring mechanism The first mainspring shaft of the mechanism is equipped with a thread reel and gears that lock the first mainspring and the base end of the cable.
A rotating gear attached to the tip of a rotating arm whose base end is rotatably supported on a first spring shaft is meshed with the gear. Then, the second spring mechanism
A gear that can mesh with the rotating gear is attached to the spring shaft, and a gear that transmits driving force to the driven side and a second spring are further provided. The swing lever, which is swingably supported within the machine frame, biases the spring in the direction in which the locking pawl provided at the lower end locks with the ratchet of the gear shaft on the driven side, and the groove in the center The cable is inserted into the cable, and a protrusion that engages with the edge of the groove of the swing lever is inserted through the cable.

[Operation] In the drive mechanism having the above configuration, by pulling out the cable wound around the thread reel of the first mainspring mechanism, the rotating arm rotates and the rotating gear meshes with the gear of the mainspring mechanism. The mainspring is simultaneously wound into the second mainspring mechanism. When the first spring mechanism is unwound, the cable is wound up, and at the end of the unwinding of the first spring mechanism, the protrusion provided on the cable swings the swinging lever and locks the swinging lever. In order to release the engagement between the pawl and the pawl wheel which is pivoted on the gear shaft on the driven side, the second spring mechanism is disengaged and other actuating members are activated.

[Example] The drawings show an example of the present invention, in which the main body 1 is formed in the shape of a penguin,
It is vertically divided from the center into a front outer shell 1a and a rear outer shell 1b. The arms 10, 10 are the support shaft 1
0a is pivotally supported inside the front outer shell 1a and is rotatable. The drive wheels 9, 9 are pivotally attached to both ends of the drive wheel shaft 8, and leg pieces 9a made of a highly flexible material are attached to the outer surfaces of the drive wheels 9, 9.
A knob 2 attached to the tip of the cable 3 is shaped like a baby penguin, and the cable 3 passes through a through hole 1c provided in the front shell 1a to the machine frame 4.
It is extended inside. A stopper 3a is provided on the tip side of the cable 3 to which the knob 2 is attached, which is formed into a protrusion by tying the cable 3 or the like. This stopper 3a is the stopper 3
It engages with a spherical protrusion 3b attached to the machine frame 4 side of a, passing through the cable 3.

The machine frame 4 is installed inside the rear outer shell 1b that constitutes the main body 1. There is a slide frame 6 on the top of the machine frame 4.
is attached to the main body 1 so as to be slidable in the front-rear direction.
That is, guide pins 4a protruding from the top wall of the machine frame 4,
4a is fitted into a long hole 5a formed in the upper part of the slide frame 6, and the slide frame 6 is fitted with a guide pin 4a,
4a and a restraining plate 5 screwed onto the upper part of the guide pins 4a, 4a, so that the guide pins 4a, 4a can be slid. A pin 34 erected at an eccentric position of a rotating plate 33 pivotally attached to an end of a gear shaft 35 in the machine frame 4 is fitted into an elongated hole 6 a formed in the side wall of the slide frame 6 . Further, a pair of wing plates 7, 7 are protruded from both sides of the side wall of the slide frame 6, and pins 7a, 7a provided upright on the wing plates 7, 7 are connected to the arm portion 1.
It fits into an elongated hole 10c formed in a protruding piece 10b protruding from the proximal end side of Nos. 0 and 10. Therefore, when the rotary plate 33 rotates with the unwinding of the mainspring mechanism, which will be described later, the slide frame 6 slides, and the arms 10 and 1
0 rotates around the support shafts 10a, 10a. Next, the spring mechanism disposed within the machine frame 4 will be explained.

Inside the machine frame 4, a first spring mechanism 13 and a second spring mechanism are arranged side by side. First spring mechanism 1
3 is composed of several members attached to the first mainspring shaft 15. At the end of the first spring shaft 15 is a first spring 20 whose inner end is locked to the first spring shaft and whose outer end is locked to the mainspring case 14.
is wrapped. The mainspring case 14 is loosely fitted onto the first mainspring shaft 15 and is fixed to the inner wall of the machine frame 4. A thread reel 16 is attached to the first mainspring shaft 15 at a position adjacent to the mainspring case 14, and the proximal end of the cable 3 is locked to the thread reel 16. Adjacent to the thread winding reel 16, a base end portion of a rotating arm 18 is loosely fitted to the first mainspring shaft 15 so as to be freely rotatable. A rotating gear 19 is rotatably supported on the distal end side of the rotating arm 18. The gear 17 with which this rotary gear 19 is always meshed is the first gear.
It is attached to a mainspring shaft 15.

The second spring mechanism 21 has a second spring shaft 23
It consists of several parts attached to.
The second mainspring 22 has its inner end locked in a locking piece 32a of a pawl plate 32 which is freely fitted loosely and extends inside the mainspring case 22a, and its outer end is engaged with a locking piece 32a of a claw plate 32 which is freely fitted into the mainspring case 22a.
It is locked to 2a. The second spring shaft 23 is freely and loosely fitted into the mainspring case 22a, and the mainspring case 22a is fixed to the inner wall of the machine frame 4. The second spring shaft 23 has a polygonal cross section (quadrilateral in the embodiment). A clutch plate 30 whose outer periphery is formed into a gear shape and also serves as a transmission gear is attached to the middle portion of the second mainspring shaft 23. The shaft hole of the clutch plate 30 has the same shape as the cross section of the second spring shaft 23, and is slidable in the axial direction of the second spring shaft 23.
It is configured so that rotational force of No. 3 is transmitted.
The pawl plate 32 has an S-shape in plan, and the second spring shaft 23 is loosely fitted into a shaft hole in the center. Also,
A protrusion (not shown) is provided at the top end of the claw plate 32 and is inclined in one direction. The clutch plate 30 and pawl plate 32 are of conventional technology as a clutch mechanism for a mainspring drive mechanism, and are used to transmit the rotation to the mainspring when the mainspring shaft rotates in the direction to tighten the mainspring, and when the mainspring shaft rotates in the opposite direction. At this time, the protrusion of the pawl plate 29 escapes from the through hole 31 of the clutch plate 30 to prevent rotational force from being transmitted to the mainspring. A gear 24 pivotally attached to the second mainspring shaft 23 is a transmission gear that meshes with the rotary gear 19 of the first mainspring mechanism 13, and a push spring 25 wound around the second mainspring shaft 23 connects the clutch plate 30 to the pawl plate. 32.

The swing lever 26 is pivotably supported within the machine frame 4 about a support shaft 28 as a fulcrum. Swing lever 26
One end of a tension spring 26b, which has a relatively weak elastic force, is locked to a locking protrusion 26a protruding from the upper part of the locking projection 26a.
The swing lever 26 is biased in the counterclockwise direction shown in the third figure. A slot 26 is provided in the middle part of the swing lever 26.
b is opened, and the cable 3 is inserted into the slot 26b. Furthermore, a locking pawl 29 is formed at the lower end of the swing lever 26 . This locking pawl 29 is provided so as to be removable from a ratchet wheel 11 which is pivotally attached to the drive wheel shaft 8 as a driven mechanism. The gear 1 rotatably attached to the drive wheel shaft 8 meshes with the transmission gear which also serves as the clutch plate 30. Further, drive shafts 9, 9 are pivotally attached to both ends of the drive wheel shaft 8.
Next, the driving states of the first spring mechanism 13 and the second spring mechanism 21 will be explained.

First, attach the knob 2 formed in the shape of a small animal to the main body 1.
When the cable 3 is pulled out from the cable 3, the cable 3 is pulled out in the direction of the arrow shown in the third figure, the first mainspring shaft 15 to which the thread winding reel 16 is attached rotates counterclockwise as shown in the third figure, and the first mainspring 20 is wound up. At this time, the rotary gear 19 meshing with the gear 17 rotates in the rotational direction of the gear 17 and meshes with the gear 23 of the second spring 21 . The gear 24 rotates in the direction of the arrow shown in the third figure, and the second spring 22 is also wound up at the same time. After the driving force is stored in the first spring mechanism 13 and the second spring mechanism 21, when the knob 2 is released, the first spring 20 is unrotated and the cable 3
is wound onto the thread winding reel 16 through the through hole 1c formed in the main body 1. At this time, the first mainspring shaft 15 rotates clockwise as shown in the fourth figure, and the rotating gear 19 meshing with the gear 17 rotates together with the rotating arm 18 in the clockwise direction as shown in the fourth figure. It meshes with a gear 36 which is pivotally attached to 35. Then, since the rotary plate 33 pivotally attached to the gear shaft 35 rotates and the eccentric pin 34 engages with the slide frame 6 to slide the slide frame 6, the arms 10, 10 attached to the main body 1 rotate. The bird will perform a movement, and the movement will look like a parent bird calling out to its young.

As the first spring mechanism 13 unwinds, the knob 2 attached to the tip of the cable 3 is drawn toward the main body 1 and reaches the position of the through hole 1c, when the spherical protrusion 3b engaged with the stopper 3a Swing lever 2
6b, thereby causing the swinging lever 26 to swing clockwise as shown in the fourth figure against the pull spring 26b. The pin 26c protruding from the top of the swinging lever 26 engages with the protrusion 37 projecting from the gear shaft 35, and the rotation of the rotating plate 33 is stopped and the operation of the first spring mechanism 13 is completed. .

Next, due to the swinging of the swinging lever 26, the locking pawl 29 provided at the lower end of the swinging lever 26 is moved to the ratchet wheel 1.
1, the second mainspring mechanism 21 is unrotated, and the main body 1 is driven by the drive wheels 9, 9.

[Effect] Thus, by pulling the knob away from the main body, driving force is stored in the first spring mechanism connected by the cable, and the second spring mechanism is activated by the rotating gear linked to the first spring mechanism. Furthermore, when the first spring mechanism is disengaged and a predetermined operation is completed, a swinging lever that functions as a stopper swings to perform other actions. Accordingly, it is possible to provide an excellent toy drive mechanism with high versatility.
