Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field to which the Invention Pertains This invention provides that when an axle is fixed and a wheel is rotated in a fixed direction, rotational energy is accumulated in a built-in power unit, and when the wheel is released, one rotational energy is released. This invention relates to a wheel with a built-in power unit that allows the wheel to be rotated in the opposite direction.

Conventional technology and its disadvantages Is the conventional wheel simply a single wheel on an axle that can rotate freely? t
Since it is a simple structure, it does not have any rotational force.Therefore, if the power part is not connected to the wheel, only when the wheel is rotated with one hand will it receive one rotational force and inertia. It rotates only when a force is applied, and when connected to a power part, the wheels must be fixed to the axle, the Ip shaft must be linked to an external spring unit or the output shaft of a motor, and the axle itself must be rotatable. Therefore, it is not possible to bend the axle into an arbitrary shape or make it at an arbitrary angle so that the wheel can be fixed at an arbitrary angle to the object.

Purpose of the Invention In view of the above-mentioned points, the present invention provides a type of wheel in which the wheel is rotatably connected to the axle, by incorporating a power unit consisting of a mainspring and a transmission gear train within the wheel.
When the wheel is forcibly rotated in one direction with respect to the axle, the mainspring is wound up, and when the wheel is released, the spring spring 8 is rotated in the other direction with respect to the fixed axle by the return force, which allows the axle to be manufactured into any shape. It is an object of the present invention to provide a wheel with a built-in power unit, in which an axle can be attached at an arbitrary angle to an object to which the wheel is attached.

Means for Achieving the Object In order to achieve the above object, the present invention provides the following steps: a. An input gear train and an output gear train are provided inside one side of a hollow wheel, and b. A gear fixed to the input gear train and a terminal gear of the output gear train are connected by +1 to each of the starting end gear of the input gear train and the end gear of the output gear train. The provided gears are meshed with a terminal gear of the input gear train and a starting gear of the output gear train, respectively.

d. One end of a mainspring provided between the wheel and the rotating body is fixed to the wheel, and the other end is fixed to the rotating plate. e. Each gear train of the wheel, the gears on the vehicle, and the The power unit is composed of a gear provided on a rotary plate and the spring.

Examples of this invention Next, one embodiment of the present invention will be described based on the drawings.

The wheel with a built-in power unit according to the present invention has a hollow wheel A. This wheel is designed to facilitate the installation of each gear train's one rotating plate and mainspring, which will be described later, and the fitting of the gears on the axle.
It is divided into two plate-shaped cases A I e A on the left and right,
Stepped recesses 1 are formed at equal intervals on the outer periphery of one case A1, and a pair of hooks 2 are protruded from the outer periphery of the other case A2 at intervals corresponding to the stepped recesses 1, so that both cases are opened. The hollow wheel A is formed by slidingly fitting and locking six pairs of opposing hooks 2 into the stepped recesses l in the @ line direction. So, wheel A
A rubber tire B having lugs 3 or a tire B having no lugs can be covered and mounted on the outer periphery of the tire. However, by forming a tire tread pattern on the outer periphery of the wheel A, it may be made to also serve as a tire.Also, in the example shown in Figure 1, the wheel A has a perfectly circular side surface, but the side surface is a regular polygon other than a perfect circle. It may also have the following.

A gear train is attached to one side of the wheel, ie, inside one case AI. This gear train is provided to transmit an amount of rotation to the axle C that is proportional to the amount of rotation of a rotary plate that receives the unwinding force of the mainspring described later. The fkX train has input gear trains g2 to g4 and output gear trains g5. There is g6.

The input gear train meshes with the gear g+ of the axle C, which will be described later, and amplifies the amount of rotation given to the rotary plate, which will be described later, to give a large rotation in a predetermined direction, and fixes a plurality of gears having a predetermined gear ratio. It is rotatably supported on a plate 4 and is constructed by sequentially meshing with each other.In the illustrated example, it consists of three gears: a starting gear g2, an intermediate gear g3, and a terminal gear g4 formed in two stages, upper and lower. , the intermediate gear g3 has its rotating shaft inserted into an arcuate elongated hole 5 provided in the fixed plate 4, so that it can be engaged with and separated from the lower stage of the terminal gear g4. Further, the upper opening of the terminal gear g4 projects from a notch provided in the fixed plate 4 in the direction of the other case A2.

The output gear train gs*gb amplifies the amount of rotation in the opposite direction of the rotary plate described later and applies it to the wheel, and the output gear train gs*gb amplifies the amount of rotation in the opposite direction of the rotary plate described later and applies it to the wheel. In the illustrated example, the gear g5 whose shaft is inserted into the arcuate long hole 6 and the case A1 are configured to be freely attached.
and a gear g6 provided near the outer periphery of the gear g6.

The axle C passes through the wheel A at the center of its side surface, and the gear g1 fixed at the middle of the axle meshes with the start gear g2 of the input gear train and the end gear g5 of the output gear train. To be precise, as will be described later, the terminal gear of the output gear train meshes only during output due to the effect of the circular arc-shaped elongated hole 6.

The wheel A is provided with a rotary plate having a boss 7 at the center, and the six-rotary plate through which the axle C is rotatably passed through the center of the boss of the rotary plate has a surface facing the gear train. A small gear g7 is provided on the outer periphery of the boss protruding from the rotary plate, and a large gear g8 is provided on the inner periphery of a protrusion 8 protruding toward the gear train at the outer peripheral end of the rotary plate. The small gear gν and the large gear g8 are the terminal gear g4 of the input gear train and the starting gear g of the output gear train, respectively.
It is meshed with 6. In this way, the small gear g on the rotating plate
By meshing l with the terminal gear g4 of the input gear train, the small gear g7 also constitutes a part of the input gear train, increasing input efficiency, and the large gear g8 of the rotating plate is connected to the output gear. By meshing with the starting end gear g6 of the train, the large gear also constitutes a part of the output gear train and increases output efficiency.

A spring power unit, which is a rotational energy storage body, is installed between the opposite side of the rotary plate C and the side of the other case A2, and the inner end of the spring protrudes to the side opposite to the small gear g7 of the rotary plate. It is fixed to the boss 7, and the outer end of the mainspring is fixed to the outer peripheral wall of the case A2 or its vicinity.

As mentioned above, the meshing 1 of the gear g+ of the axle C with the starting end gear g2 of the input gear train and the end gear g5 of the output gear train
Small gear g7 in the center of the rotary plate and the terminal gear g of the input gear train
In order to facilitate the arrangement of each gear train such that the large gear g8 on the outer periphery of the rotating plate can mesh with the starting gear g6 of the output gear train, the fixed plate 4 It is particularly formed in a U-shape (C-shape or horse-shape), and rotates between the outer periphery of the fixed plate and the outer periphery inner surface of the wheel A so that the axle C is located in the central notch. It is fixed to the side of one case AI with an interval slightly larger than the thickness of the protruding edge 8 of the plate.

As illustrated in FIG. 5, the mold @C is fixed to a base 9 such as a chassis of a traveling toy.

With the above configuration, when the axle C is fixed and the tire B, or if the wheel also serves as a tire, the wheel A itself is pressed against the running surface etc. and moved in a predetermined direction (to the left in FIG. 4), Since the wheel A is rotated counterclockwise in Fig. 4 and the axle is fixed, the input gear train is Each gear g
2 to g4 rotate in the direction shown by the thin line arrow in Fig. 4, and therefore the pinion g1 of the one-turn plate is rotated clockwise in the same figure, and as a result, the rotating plate C is also rotated clockwise. , the mainspring power section is wound up, and rotational energy is multiplied by Ti.

In this case, since the axis of the intermediate gear g3 of the input gear train is moved in the direction of the axle C along the arcuate elongated hole 5, the gears g2. g4, while the shaft of gear g5 of the output gear train is moved along the arcuate long hole 6 in the opposite direction to the axle C, and *wheel g! Since the mesh is released, the rotational force generated from the large gear g8 of the rotary plate and the rotational force applied from the axle C do not compete with each other.

After winding up the mainspring in this way, when the wheel is released by releasing the hand holding the moving toy to which this wheel is attached, rotational energy is released from the mainspring power part, and the large gear g8 and small gear of the rotating plate are released. The gear g1 rotates in the direction indicated by the thick arrow in FIG. 4, and each gear gs
*gz applies a counterclockwise rotational force to the starting end gear g6 of the output gear train, and a clockwise rotational force to the end gear g4 of the input gear train. However, since the axis of the intermediate gear g3 of the input gear train is moved toward the outer end of the circular arc-shaped elongated hole 5, the terminal gear g4 and the intermediate gear g3 are separated from each other, whereas the axis of the gear g5 of the output gear train is The terminal gear g5 is moved toward the inner end of the circular arc-shaped elongated hole 6, and the terminal gear g5 is surely engaged with the gear g1 of the axle C, and since the gear of the axle does not rotate, the output gear gb+gs is shifted in the same direction around the axle C. Since the vehicle revolves clockwise in the figure, the wheel A is rotated in the same direction, causing the traveling toy to travel rightward in the figure.

As mentioned above, the wheel according to the present invention has a structure in which the wheel itself outputs power, so there is no restriction that the wheel is connected to an external power section in a transmission system as in the past. It is possible to attach the wheel to a desired position with respect to the base without having to do so, and it is possible to realize various wheel attachment modes.

For example, as shown in FIG. 6, a base 9A having the appearance of a running toy or an animal has wheels attached to the front underside, and four parts opening downward are provided in the center of the base. , Attach rod-shaped or disc-shaped stays on both sides of the four parts,
By accommodating the wheel according to the present invention in the recess and fixing the axle to the stay, it is possible to provide a wheeled wheel-like traveling toy or monster, or to provide a mounting plate in place of the recess.

One or more wheels according to the present invention are mounted on each side of the mounting plate, and an axle is fixed to the mounting plate to provide a running toy as illustrated in FIG. be able to.

Further, since the axle does not need to be limited to a shape and structure for transmitting rotational force from an external power unit, it can have any shape and can be attached to the base at any angle.

The one in Fig. 5 is a 4 = 1-digit one that uses an approximately two-shape axle to rotate at any angle with respect to the base 9 and fix it at that angle. Based on the wheels as shown.

You can enjoy moving it to any position relative to the stand and running it in various poses.

Effects of the Invention As described above, according to the present invention, rotational energy is stored in the wheel by a small amount of rotation of the wheel in one direction, and the rotational energy is gradually released by releasing the wheel, so that the wheel rotates in the opposite direction. It is possible to provide a wheel with a built-in power unit that rotates a large amount. Therefore, since the structure is such that the wheels themselves output power, there is no restriction that the wheels are attached to the base in relation to an external power unit in terms of transmission system, as in the past, and the wheels can be attached to the base as desired. It can be mounted in any position, and various wheel mounting modes can be realized. Also,
The axle does not need to be limited to a shape structure for transmitting rotational force from an external power part, so it can have any shape.)
It becomes possible to install it at an angle of 1, a with respect to the , ti stand.
