Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a drive device suitable for use in a running toy that uses a spring as a drive source, and particularly to a drive device for a running toy that can freely change the speed of the running toy by releasing the mainspring to make it run. Regarding.

[Conventional technology]

A mainspring is used as the driving source, and when you push the car body backwards by hand and rotate the wheels in the opposite direction, the mainspring is wound up and stores energy.
Traveling toys have been widely known in which when the hand is released, the mainspring disengages and rotates the wheels, causing the vehicle to move forward. Conventionally, the means of adjusting the speed of the mainspring is to provide resistance to the release of the mainspring. Speed is controlled by a gear mechanism. Provides resistance to wheel rotation. There are various methods such as

[Problems to be solved by the invention]

The above-mentioned various conventional adjustment means are used when the mainspring's discharging action is directly transmitted to the wheels when running at high speed, when resistance is applied to the discharging of the mainspring, or when a reduction gear is interposed in the middle; , low-speed running occurs when resistance is applied to the wheels, but not only are the devices that carry out these means complicated in structure, but the switching operations are surprisingly troublesome, making it difficult to change speeds easily. There is a problem that the speed switching operation does not have the same feeling as in a real car, and furthermore, when you try to wind the mainspring by rotating the wheels in the opposite direction when the speed is set to low speed, the resistance of the wheels is large. Therefore, it was troublesome to have to remove the low-speed running setting each time when tightening.

[Means for Solving the Problems 1] The present invention has been made to solve each of the above-mentioned problems, and the first object of the present invention is to provide a simple structure. It is easy to manufacture and assemble, and
It is easy to switch between slow and fast speeds, and the switching operation can be performed with a lot of feeling.
The object of the present invention is to provide a driving device for a traveling toy that is devised so that even when the mainspring is tightened, the wheel can be easily reversed and the mainspring tightened with a small amount of force in the same way as when the mainspring is set at high speed.
In addition to the above objects, the second object of the invention is to:
To provide a drive device for a running toy that can freely control the start of running by locking the release of a mainspring. In order to achieve each of the above-mentioned objects, the first aspect of the present invention provides a traveling toy that runs by rotating wheels in the forward direction by the unloading action of a spring that is wound up by rotating the wheels in the opposite direction. , a transmission gear is attached to the governor shaft which is in contact with the governor plate and is always subject to rotational resistance, and a switching gear is attached to the switching shaft which is movably supported in the elongated hole of the frame. meshes with the operating gear that transmits transmission between the axle gear attached to the wheel shaft and the drive gear on the mainspring side,
The switching gear is configured to move and mesh with the transmission gear when the operating gear rotates due to the disengagement of the mainspring and travels and rotates the wheel, while the frame is configured to prevent movement of the switching gear. In the second aspect of the present invention, the speed of the running toy due to the release of the mainspring can be adjusted to two speeds, slow and fast. By engaging the stopper with the gear, and by providing a release element on the switching lever that can release the stopper from the drive gear, even if the mainspring is wound, it can be freely released using the operating lever. It is configured so that it can be controlled. DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Figures 1 to 3 show the structure of the first invention, and the reference numeral 1 in the figures indicates a frame attached to the inside of the traveling toy concrete T. As shown in the plan view shown in FIG. 1, the inside of is partitioned into a total of three partitions IA, 1B, and 1G by two partition plates 1a and 1b arranged in parallel in the middle. 2.2 is the front wheel, and 2a is the axle of the front wheel attached to the toy body T. Also, 3.3 is the rear wheel, and these rear wheel axles 3a
is rotatably inserted (erected) into the frame 1 inside the toy body T. In FIG. 3, reference numeral 4 denotes an axle gear attached to the axle 3a of the rear wheel, which is located at the second uIB of the frame 1. Reference numeral 5 designates an operating gear rotatably mounted in the second chamber 1B, which is configured to mesh with the axle gear 4 and rotate in conjunction with the axle gear 4. The transmission gear 6 shown in FIGS. 1 and 3 is always meshed with the operating gear 5, and the drive gear 8 rotates integrally with the mainspring 7 housed in the first chamber 1A of the frame 1 as shown in FIG. The transmission shaft 6a to which this gear 6 is attached is movably supported in long holes 1al (Ib side omitted) bored in the partition plates 1a and 1b (Ib side is omitted) as shown in Fig. 3. , As shown by each arrow in Figure 5 (a), the toy concrete T
When the rear wheel 3 is rotated backward in the clockwise direction, the rotation of the operating gear 5 is transmitted to the drive gear 8 to tighten the mainspring 7. In FIGS. 1 and 2, reference numeral 9 denotes a large driving gear integrally formed concentrically with the driving gear 8 of the mainspring 7, and this large gear 9 is a general intermediate pinion in the first chamber 1A of the frame 1. It always engages with 10 and enters L. Reference numeral 11 denotes an intermediate large gear integrally formed with the intermediate small gear 10, and the gear shaft 12 to which these rain intermediate gears 10111 are attached is formed through elongated holes 1C1 ( When the large driving gear 9 is driven and rotated by the mainspring 7 as shown by the arrow in FIG. Then, the intermediate large gear 11 meshes with the interlocking gear 13. This interlocking gear 13 is attached to the operating shaft 5a on which the operating gear 5 is attached. Therefore, when the mainspring 7 is released, the operating gear 5 is moved through the intermediate small gear 10 and the large gear 11 as shown in FIG. As shown in Figs. 1 and 3, the toy body T can be rotated in the clockwise direction and the rear wheels 3 are rotated in the counterclockwise direction to make the toy body T run to the left in the figure. 14 is a switching gear that is always meshed with the operating gear 5, and the switching shaft 15 to which this gear 14 is attached is connected to the first and second partition walls 1a. side omitted)
When the mainspring 7 is wound up as shown in Fig. 5(a), it is moved upward in the elongated hole 1a3 by the rotation of the operating gear 5, and as shown in Fig. 7(i). ), when the operating gear 5 is rotating as shown by the arrow in the figure in response to the discharging operation of the mainspring 7, it is configured to move downward within the elongated hole 1a3. In FIGS. 1, 3, and 4, 16 is a speed regulating shaft installed across the second chamber 1B and third chamber 1G of the frame 1,
An interlocking gear 17 is attached to the second chamber 1B side of this shaft 16, and a governor gear 18 is attached to the third chamber 1C side, and the switching gear 14 is arranged as shown in FIG. 7(A). long hole 1
When moving downward in a3, the interlocking gear 17 meshes with the switching gear 14, and the governor shaft 16 and the gear 18 rotate in conjunction with each other. One is a speed governor plate 20 rotatably supported in the third chamber 1C of the frame 1, and upper and lower teeth 19a and 19b formed in a notch at the tip of this plate mesh with the speed governor gear 18. This provides resistance to the rotation of the regulating shaft 16. (7th
(See Figure (C)) Next, reference numeral 21 denotes a switching lever 22 rotatably supported in the second chamber 1B of the frame 1, and the bent tip 21a of this lever 21 is always on the movement path of the switching shaft 15. The lever 21 that protrudes to prevent the downward movement of the switching shaft 15 is rotated as shown in FIGS. It can also happen. The drive device of the present invention configured as described above is shown in FIG.
If the rear wheel 3 is rotated in the opposite direction as in
, the operating gear 5, and the transmission gear 6 to the driving gear 8, and the mainspring 7 is thereby tightened. During this tightening, the switching gear 14 is rotated through the elongated hole by the rotation of the operating gear 5.
Since the mainspring 70 is always moved upward along the a3 as shown in FIG. This can be done with relatively little force. Furthermore, when tightening the mainspring 7, the gear shaft 12 also moves upward in the elongated hole 1c1 as shown in FIG. I can do it. On the other hand, when the wound mainspring 7 is released, the intermediate large gear 11 moves downward and meshes with the interlocking gear 13 as shown in FIG. Since it rotates in the upper clockwise direction, the axle gear 4 is rotated in conjunction with the rear wheel 3 to rotate the rear wheel 3 in the forward direction, thereby making it possible for the toy body T to run in the direction of the arrow in the figure. At this time, the transmission gear 6 moves upward along the elongated hole 1a1 and disengages from the driving gear 8, so that the resolving force of the mainspring 7 is smoothly transmitted to the axle gear 4 via the operating gear 5. As described above, according to the drive device of the present invention, the rear wheel 3
The folding elasticity of the mainspring 7 tightened by the reverse rotation of the mainspring 7 can be transmitted again to the rear wheel 3 side to make the toy body T run.In the present invention, in particular, the running speed of the mainspring 7 can be adjusted to slow or slow. It can be adjusted in two ways. That is, FIG. 6(b) shows the set state when the toy concrete T is driven at high speed. In this set state, the switching lever 2
1 connects its tip 21a to the switching shaft 15; □, machining, -
. □□□, Eng. , 6o butts,. Even when the gearwheel 5 rotates, the switching gear 14 continues to rotate at the position shown and does not mesh with the interlocking gear 17 on the governing shaft 16 side. The wheel 3 can be rotated at high speed (constant speed). Furthermore, when the switching lever 21 is rotated as shown in FIG.
Since the rear wheels 3 mesh with each other and provide resistance to the rotation of the operating gear 5, the rotation of the rear wheels 3 is slowed down and the traveling toy (2) travels slowly. Next, based on the description in FIGS. 8 and 9, the second embodiment of the present invention will be described.
The second invention will be explained. Incidentally, in the drawings, the same constituent members as those in the first invention are designated by the same reference numerals, and their explanations are omitted. The second invention is characterized in that the driving device for a traveling toy according to the first invention is configured such that discharging of the mainspring 7 can be freely controlled. That is, in FIG. 8, reference numeral 21b denotes a lower tip part connected to the tip side of the switching lever 21, and the switching lever 21 is connected to the tip part 21a on the upper stage side.
1 is formed in a substantially U-shape, and upper and lower release elements 21a1 and 21b1 are formed in the shape of a protrusion on the side surface of each tip.
are provided in a protruding manner, and both of these release elements 21a1 and 21b1 are inserted into guide elongated holes 1a bored in the first partition plate 1a of the frame 1.
4.1a5 protrudes into the first chamber 1A. In FIG. 9, reference numeral 30 denotes a stopper 31 which is pivotably supported in the first chamber 1A of the frame 1 so as to be able to move up and down. (See virtual line). These locking teeth 32 and locking protrusions 33
The drive gear 8 engages with the mainspring 7, which rotates counterclockwise in the drawing, in the discharging rotation direction and locks its free rotation. Release child 21
a1.21b1 is the rear end portion 30a of the stopper 30;
The release element 21 protrudes to a position where it can be pressed.
Even if a1.21b1 pushes the rear end portion 30a, the entire stopper 30 can be rotated in the double-clockwise rotation direction about the shaft support 31 as shown by the solid line in the figure, and the engagement can be released. According to the present invention configured as described above, after winding the mainspring 7, the switching lever 21 is rotated so that the upper end 2ia side is pressed against the switching shaft 15 as shown in FIGS. 8 and 9. In this case, the upper release element 2Ial pushes the stopper 30 to the state shown by the solid line in FIG. However, the toy concrete T runs at high speed. A position where the switching lever 21 is slightly returned from the state shown in FIGS. 8 and 9 is a neutral position, and in this state, the stopper 30 engages the middle drive tooth 8 and rotation is stopped. When the switching lever 21 is rotated horizontally from the state shown in both figures, the lower stage release element 21b1 releases the stopper 30 and allows the drive gear 8 to rotate, but in this state, the upper stage end portion 21a
is moved backward from the moving path of the switching shaft 15, and the operating gear 5 is affected by the speed governor shaft 16 and rotates slowly, so that the toy body T starts running slowly at the same time as the switching lever 21 is actuated.

【Effect of the invention】

Since the drive device for a running toy according to the present invention is as described above, the speed of the running toy can be switched between two speeds, slow and fast, by means of a spring. It has the feature that the traveling of the traveling toy can be controlled freely by locking the discharging of the bullet with a stopper. However, in the present invention, the above-mentioned speed change and the engagement and disengagement of the stopper with respect to the mainspring are all controlled by the switching lever. Since this can be done by operating a lever, it is possible to perform highly realistic operations and have fun playing and S. When the wheel is rotated in the opposite direction to wind the mainspring, the switching gear is inserted into the long hole according to the rotation of the operating gear. It also has the advantage that the mainspring can be tightened smoothly with less force without encountering resistance from the regulating shaft because it moves along the same axis and disengages from the interlocking gear on the regulating shaft side. , a gear mechanism, a switching lever, and a stopper, which can be constructed relatively easily, making it suitable for use in various running toys that use a spring as a drive source.
