Description

[Detailed Description of the Invention] Prior Art to which the Invention Pertains This invention relates to a wheeled vehicle that can change its form in various ways by changing the positional relationship of the wheels with respect to the base, and can run in any of the forms. .

Prior Art and Its Disadvantages In a traveling toy having a plurality of wheels, the positional relationship of the wheels with respect to the base can be changed,
A running toy whose running form can be changed is disclosed in Japanese Utility Model Application Publication No. 60-99996 and Japanese Utility Model Application Publication No. 45-5132.
It is known from the publication No.

However, in all of these prior art, the left and right front wheels and the left and right rear wheels are connected by an axle and a leg lever, respectively, so by opening and closing the angle formed by the front wheel leg lever and the rear wheel leg lever, The position of the wheels relative to the base can be changed. Therefore,
The scope of change in the form of a traveling toy is very narrow, and is limited to only the size of the gap between the front and rear wheels, the height of the base, and the slope of the front and rear leg levers.

In addition, the power section is installed between the leg levers of the rear wheels, and is commonly used for a pair of rear wheels (in 1987-
99996), the running mode of a running toy is always constant and hardly changes.

Purpose of the Invention The present invention has been made in view of the above points, and it is possible to change the position of a plurality of wheels with respect to the base independently, thereby widening the range of changes in the running form of a running toy. It is an object of the present invention to provide a wheel running body which is capable of varying the driving force of each wheel so that one running toy can exhibit various running modes.

Solution to Problem In order to achieve the above object, the wheeled vehicle according to the present invention has a plurality of mounting arms on both left and right sides of the base, each of which has its base ends independently rotated around a horizontal axis and fixed at an arbitrary angle. It is mounted in a straight line, and a wheel with a built-in power section is attached to the free end of each mounting arm.

Function: By independently rotating the mounting arms of the plurality of wheels, the positions of the wheels relative to the base can be changed in various ways. You can extend the mounting arms to the front and back of the base to place the wheels at the front and back of the base, or extend the mounting arms below the base at any angle to place the wheels at the front and rear of the base. The wheels can be placed side by side, front and back opposite each other, or the mounting arms can be rotated above the base so that the wheels are positioned below the inverted base. Additionally, the base can be bent forward or backward.

Since each wheel has a power section, by adjusting the ground pressure of each wheel during pullback, the amount of energy stored in the power section of each wheel can be made equal or uneven. The running mode differs depending on the inequality of the driving force of each wheel during running.

Embodiment of the Invention Next, an embodiment of the invention will be described with reference to the drawings.

The wheel running body according to the present invention generally includes a base A, at least four attachment arms B rotatably attached to the base at the base end, and a power source attached to the free end of each of the attachment arms. It consists of a built-in wheel C.

The base A can be connected to a mounting body D such as a running toy with wheels removed or an imitation animal having various shapes, as shown in the illustrated example, via a detachable connection means.

As shown in FIG. 2, such a coupling means may include, for example, a protrusion 1 or groove provided on the upper surface of the base A and a groove 2 or protrusion provided on the lower surface of the mounting body D. As shown in FIG. 3, projections 3a and 3b provided at the front and rear of the mounting body D are fitted into holes in elastic locking portions 4a and 4b provided at the front and rear of the base A,
The attachment body can be clamped and connected by elastic return of the locking portion, or any other known means can be used. In addition, an ordinary running toy that is equipped with a power part and wheels and can run independently can be used as an attached object.
This may be detachably fixed to the base A.

Each mounting arm B has its base end inserted into the base from both the left and right sides of the base on at least two parallel straight lines passing through the base A, and each mounting arm is independently inserted into the base. It is attached so that it can rotate around the end and be fixed to the base at any angle. In such a mounting structure, the base A is divided into upper and lower parts by the mounting arm through hole 5, and the upper part 6 and lower part 7 are connected by a tightening member 8 such as a screw or bolt nut, and the tightening member is tightened. Depending on the degree, the mounting arm B
A device that adjusts the frictional force between the base end of the base A and the through hole 5 of the base A to make the mounting arm B rotatable or non-rotatable relative to the base A, and a fourth As shown in the figure, two upper and lower members 11 are molded from hard synthetic resin and have semicircular female gears 9 and 10 at both ends.
are fixed to the base A at the center of the member with the semicircular female gears facing each other so that the semicircular female gears constitute a complete circular female gear, and both ends of both members are left free to form the complete circular female gear. By fitting the male gear 12 formed at the base end of the mounting arm B to the circular female gear, when the mounting arm B is rotated, each of the semicircular female gears of the two members is connected to each peak and valley of the male gear of the mounting arm. There are some types that allow the mounting arm to rotate by expanding and contracting in response to the rotation, and when the rotation is stopped at an arbitrary angle, it is fixed at the stopped position by the contraction of the complete circular female gear.

A wheel C having a built-in power section is attached to the free end of each of the attachment arms B. This wheel includes a wheel 13 that is fixed to the mounting arm, a wheel 14 that is rotatably held with respect to the mounting arm, a tire 15 that covers the outer periphery of the wheel, and a tire 15 that is built into the wheel and that is attached to the wheel. It consists of a power unit that has a mainspring that is wound up by rotation in one direction to store rotational energy, unwinded to release rotational energy by releasing the wheel, and rotates the wheel in the opposite direction. The axle 13 may be integrally provided at the lower end of the mounting arm B.

Power units that use the mainspring as a rotational energy store usually have an input gear train to increase the efficiency of the input to the mainspring (winding the mainspring as much as possible with a small amount of rotation of the wheel) and an input gear train to increase the efficiency of the output from the mainspring. It has an output gear train (to rotate the wheel as much as possible with a small amount of unwinding of the mainspring).

5 to 8 show an example of a wheel incorporating such a power unit.

The wheel with a built-in power unit according to the present invention has a hollow wheel 14. This wheel has left and right dish-shaped cases 14 to facilitate the installation of each gear train, rotary plate, and mainspring, which will be described later, and the fitting of the wheel gears.
_{The case} 141 is divided into _{two parts} , with stepped recesses 16 formed at equal intervals on the outer periphery of one case ₁₄₁ ,
A pair of hooks 17 are provided protrudingly on the outer periphery of the other case 14 ₂ at a distance corresponding to the stepped recess 1 ,
The hollow wheels 14 are formed by arranging the openings of the two cases to face each other and slidingly fitting and locking each pair of hooks 17 into the stepped recesses 16 in the axial direction. A lug 1 is attached to the outer circumference of the wheel 14.
Rubber tires 15 with 5a or tires 15 without lugs can be mounted on the cover. However, by forming a tire lead pattern on the outer periphery of the wheel 14, it may also serve as a tire.
Further, although the wheel 14 has a perfectly circular side surface in the illustrated example, it may have a regular polygonal side surface other than a perfect circle.

One side of the wheel, i.e. one case 1
4 A gear train is attached to the inside of ₁ . This gear train is provided to transmit an amount of rotation to the axle shaft 13 that is proportional to the amount of rotation of a rotary plate that receives the unwinding force of a mainspring, which will be described later. The gear train includes input gear trains g ₂ to _{g 4} and output gear trains g ₅ and g ₆ .

The input gear train meshes with the gear _g1 of the axle shaft 13 to amplify the amount of rotation given and gives a large amount of rotation in a predetermined direction to the rotating plate D, which will be described later, and includes a plurality of gears having a predetermined gear ratio. are rotatably supported on a fixed plate 4 and are sequentially engaged with each other. In the illustrated example, the starting gear g ₂ , the intermediate gear g ₃ ,
It consists of three gears, the terminal gear _g4 , which is formed in upper and lower stages, and the intermediate gear _g3 has its rotation axis connected to the fixed plate 18.
The terminal gear g ₄ is inserted through the arc-shaped elongated hole 19 provided in the
It is said that it is possible to engage and separate from the lower stage of the Also,
The upper stage of the terminal gear _g4 projects from a notch provided in the fixed plate 18 toward the other case ₁₄₂ .

The output gear trains g ₅ and g ₆ amplify the amount of rotation in the opposite direction of the rotary plate 20 described later and give it to the wheel.
A plurality of gears having a predetermined gear ratio are sequentially meshed and are rotatably attached to the fixed plate 18. In the illustrated example, it is composed of a gear g ₅ whose shaft is inserted through the arc-shaped elongated hole 21 and a gear g ₆ provided near the outer periphery of the case 14 ₁ .

The axle 13 passes through the wheel 14 at the center of its side surface, and the gear _g1 fixed at the middle of the axle is meshed with the start gear _g2 of the input gear train and the end gear _g5 of the output gear train. be.
To be more precise, as will be described later, the terminal gear of the output gear train meshes only during output due to the action of the circular arc-shaped elongated hole 21.

A rotating plate 20 having a boss 22 at the center is provided inside the wheel 14, and the axle 13 is rotatably passed through the center of the boss of the rotating plate.
The rotary plate 20 has a small gear _g7 on the outer periphery of a boss protruding from the surface facing the gear train, and a large gear g7 on the inner periphery of a ridge 23 protruding toward the gear train at the outer peripheral end of the rotary plate. ₈ are respectively provided, and the small gear _g7 and the large gear _g8 are meshed with the end gear _g4 of the input gear train and the start gear _g6 of the output gear train, respectively, at predetermined positions on the rotary plate. In this way, by meshing the pinion _g7 of the rotating plate with the terminal gear _g4 of the input gear train, the pinion _g7 also constitutes a part of the input gear train, increasing input efficiency. In addition, the large gear g ₈ of the rotating plate is output as the starting gear g ₆ of the gear train.
By meshing with the large gear, the large gear also forms part of the output gear train, increasing output efficiency.

The opposite side of the rotating plate 13 and the other case 14 ₂
A mainspring 24, which is a rotational energy storage body, is installed between the side surface of the case and the inner end of the mainspring is fixed to a boss 22 that protrudes on the side opposite to the small gear _G7 of the rotating plate, and the outer end of the mainspring is attached to the case. 14 It is fixed on or near the outer peripheral wall of ₂ .

As mentioned above, the gear g ₁ of the axle 13 meshes with the starting gear g ₂ of the input gear train and the ending gear g ₅ of the output gear train, and the small gear g ₇ at the center of the rotating plate 20 meshes with the ending gear of the input gear train. In order to facilitate the arrangement of each of the gear trains such that they can mesh with G ₄ and the large gear G ₈ on the outer periphery of the rotary plate and the starting gear G ₆ of the output gear train, the fixed Plate 18 is especially U
The rotating plate 20 is formed in a C-shape (or a C-shape or a horse-shaped shape) so that the axle 13 is located in the center notch thereof, and between the outer periphery of the fixed plate and the outer periphery inner surface of the wheel 14. One case 14 1 with a gap slightly larger than the thickness of the ridge 23 of the case 14 ₁
It is fixed on the side of the

With the above configuration, the tire 15, or if the wheel also serves as a tire, the wheel 14 itself,
When pressed against a running surface and moved in a predetermined direction (leftward in FIG. 8), the wheel 14 is rotated counterclockwise in FIG. 8, and since the axle is fixed, the gear g ₁ on the axle and Due to the relative rotation with the starting end gear _g2 of the input gear train built in the wheel, each gear _g2 to _g4 of the input gear train rotates in the direction shown by the thin line arrow in FIG. The small gear _g7 of No. 20 is rotated clockwise in the figure, and as a result, the rotating plate 13 is also rotated clockwise, so
The mainspring 24 is wound up and rotational energy is stored.

In this case, the shaft of the intermediate gear g ₃ of the input gear train is moved in the direction of the axle shaft 13 along the circular arc-shaped elongated hole 19, so it meshes reliably with the gears g ₂ and g ₄ on both sides, whereas the output The shaft of gear g ₅ of the gear train has an arc-shaped long hole 2
1 in the opposite direction to the axle shaft 13 and is disengaged from the gear g ₁ , so that the rotational force applied from the large gear g ₈ of the rotary plate 20 and the rotational force applied from the axle 13 compete with each other. There is no.

After winding up the mainspring in this way, when you release your hand holding the moving toy to which this wheel is attached and release the wheel, rotational energy is released from the mainspring E and the large gear g ₈ of the rotating plate 20 is released.
_The small gear g ₇ rotates in the direction indicated by _the thick arrow in FIG _. Clockwise rotational force is applied to each end gear g ₄ . However, since the axis of the intermediate gear _g3 of the input gear train is moved toward the outer end of the arc-shaped elongated hole 19, the terminal gear _g4 and the intermediate gear _g3 are separated from each other, whereas the gear g of the output gear train ₅ is moved toward the inner end of the arcuate elongated hole 21, and the terminal gear g ₅ is connected to the gear g ₁ of the axle 13.
It definitely meshes with the. Since the gears on the axle do not rotate, the output gears g ₆ and g ₅ revolve around the axle 13 clockwise in the figure, so the wheel 14 rotates in the same direction, and the running toy etc. The vehicle will travel to the right in the figure.

As mentioned above, since the power section is built into the wheel C, there is no need for a fixed structure for transmitting rotational force from the power section provided on the base to the axle as in the past, and the mounting arm B is attached to the base. It is possible to have any shape that is rotatable with respect to A.

As shown in FIG. 9, each mounting arm B is independently and rotatably mounted parallel to the base 14 on at least two straight lines.
As shown in FIG. 10, each mounting arm B can be extended in both the front and rear directions of the base A to place the wheels 13 on the front and rear of the base, or as shown in FIG. Alternatively, as shown in Figure 12, you can turn the base upside down and the attached body upside down, or as shown in Figure 13, you can tilt the base forward and move the wheels forward accordingly. Furthermore, as shown in FIG. 14, the left and right mounting arms can be tilted forward and rearward, respectively, so that the wheels can be positioned forward and rearward, respectively. Moreover, since each wheel has a built-in power unit, when the running body in any pose is manually pulled back and released, the wheels rotate and run due to the release of the rotational energy stored in the mainspring.

Effects of the Invention As described above, according to the present invention, there is provided a base to which a mounting body having a desired shape can be connected, and one end of which can be fixed to the base at an arbitrary rotation angle, and each of which is independent of the other. A rotatably attached mounting arm,
Since it consists of a wheel with a built-in power unit attached to the free end of the mounting arm, the wheel can be moved to any position relative to the base by rotation of the mounting arm, transformed into various poses, and run in that pose. is possible,
It allows for play methods that cannot be predicted from conventional products.

In addition, since each wheel has a built-in power unit, it can easily travel on surfaces with high running resistance, just like a four-wheel drive vehicle, for example.
Furthermore, since all wheels have a power section, the amount of rotational energy stored in the power section of each wheel can be made equal or unequal by adjusting the ground pressure of each wheel during pullback. Therefore, it is possible to change the running mode.

As described above, the wheel running body according to the present invention is
It has a diversity in running form and mode that is not seen in conventional running toys.
