Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a motorized articulated vehicle on which several people can ride in a row and can also train teamwork while having fun.

(Conventional technology) Conventionally, there are bicycles that can accommodate three to five people in a row.

For example, a five-seater bicycle has five seats between the front and rear wheels on one frame, and each seat has a pedal that acts on the drive wheel (for example, the rear wheel) via a chain. It is provided. The bicycle can be run with a sense of unity by five people exerting their strength and pedaling together.

(Problem to be solved by the invention) However, since this bicycle has a one-piece frame that is long in the front and back direction, it can run smoothly in a straight line, but only the person in the lead can change the direction of travel. , and others are unable to change the direction of travel, so they simply pedal, unable to drive aggressively and unable to cultivate teamwork. Another problem is that when changing the direction of travel, only large curves can be used.

(Means for Solving the Problems) In order to solve the problems of the conventional example, the present invention provides a leading car that includes wheels, a power device for rotationally driving the wheels, a seat, and a handle, respectively, on a frame. , consists of a connected car equipped with wheels, a handle, and a seat on a frame that is rotatably connected to the rear end of the frame of the leading car, and the front end of the frame of this connected car has horizontal and vertical rotation. A combination of first and second rotatable connecting members is provided, and the first and second connecting members are provided in combination. A support shaft passing vertically through the second connecting member in a rotatable manner has a wheel at the lower end and a handle at the upper end. The terminal parts are fitted and rotatably connected by a pivot shaft, and the rear end part of the frame of this connected car is connected to the front second connecting member of the same connected car as described above, which is rotatably connected in sequence. The rear end of the frame of the rearmost connected vehicle is equipped with wheels, making it a powered connected vehicle.

(Function) In this motorized articulated vehicle, the leading car moves forward with its wheels driven by a power device provided therein. The coupled vehicles sequentially coupled to the rear end portion of the frame of the leading vehicle and the rearmost coupled vehicle coupled to the rear end portion of the frame of the coupled vehicle travel while being towed by the leading vehicle.

The connection parts between the rear end of the frame of the leading car and the front end of the connected car, and the rear end of the frame of this connected car and the front end of the connected cars that are successively connected, can be rotated horizontally and vertically. Since it is movable, when the leading car turns the steering wheel to change the direction of travel, the connecting part to the connected cars connected to it can rotate horizontally, so the connected cars can also turn the steering wheel accordingly. The direction of travel can be changed, and the connecting portion rotates vertically when traveling on uneven road surfaces.

This motorized articulated vehicle cannot run unless everyone drives it with teamwork; for example, if even one person turns the steering wheel in the wrong direction, the vehicle will be unable to run, allowing the vehicle to develop teamwork while having fun.

In order to prevent the handles 5, 5 from turning at a steep angle, there is a
A locking pin 11 that locks is provided.

12 is a connecting car connected to the rear end portion 2b of the frame 2 of the lead car 1 so as to be vertically and horizontally rotatable;
A substantially U-shaped first coupling member 14 is provided at the front end of the frame 13 of the coupling vehicle 12, and is located between the upper and lower pieces 14a and 14b of the U-shaped first coupling member 14. To,
A second connecting member 1 whose tip end is a flat bifurcated portion 15a
The proximal end portions 15b of the first. A wheel holder 17 is attached to the lower end of a support shaft 16 that vertically and rotatably passes through the second connecting member 14, 15, and a wheel 18 is rotatably attached to this wheel holder 17, and a footrest. 19 is also installed. Further, a handle 20 is provided at the upper end of the support shaft 16, and a handle 20 is provided at the upper end of the first connecting member 14 when the handle 20 is turned at a steep angle.
A locking pin 21.21 is provided which locks at zero.

22 is a seat provided in the middle of the frame 13.

The rear end portions 2b of the frame 2 of the leading car 1 are fitted into the planar forked portion 15a of the second connecting member 15 of the connected car 12 configured as described above, and these rear end portions 2 are fitted.
b and the plane bifurcated portion 15a are connected by inserting a pivot shaft 23 so as to be rotatable in the vertical direction.

Also, the rear end portion 13 of the frame 13 of this coupled vehicle 12

In this embodiment, the rearmost coupled vehicle 12' has a frame 13' having a triangular shape, with a first coupling member 14' provided at one corner and wheels mounted at the other two corners. It differs from the coupled vehicle 12 in that it is a tricycle with holders 17', 17' and wheels 18', 18' attached to these wheel holders 17', 17'; this is because the coupled vehicle does not fall over when stopped. In order to prevent it from falling over, it is necessary not only to have a three-wheeled structure as in this example, but also to make the rearmost connected vehicle a two-wheeled structure.
Thereafter, the wheel holder of the wheel may be provided with a stand that is used by rotating from the horizontal direction to the vertical direction when the vehicle is stopped.

Since this motorized articulated vehicle is constructed as described above, the leading vehicle 1 moves forward with its wheels 6, 6 being driven by the power device 7 provided therein. This lead car 1
The connected vehicle 12 sequentially connected to the rear terminal portion 2b of the frame 2 of
It runs while being towed by.

The connecting portion between the rear end portion 2b of the frame 2 of the leading car 1 and the front end portion of the connecting car 12 is rotatable horizontally and vertically, so that it can be rotated to the left as shown in FIG. When turning to
0 forward with your foot and turn the steering wheel 5 to the left to change the direction of travel to the left.The driver of the articulated vehicle 12.12' follows this and pushes the right footrest forward and turns the steering wheel to the left. , the travel of the entire motorized articulated vehicle can be changed to the left. In order to change the direction of travel, the vehicle cannot smoothly turn to the left unless the driver at the front of the vehicle performs the left turn operation sequentially from the driver of the connected vehicle to the driver of the connected vehicle. For example, if one of the drivers of a combined car fails to turn the steering wheel, or turns the steering wheel in the wrong direction, the overall driving becomes unnatural, or an abnormal force is applied and the combined car lifts off. Therefore, this motorized articulated vehicle can run smoothly by all the drivers of the lead vehicle and the coupled vehicle operating the footrests and steering wheel with good teamwork. If you want to turn to the right, do the opposite of the above.

In addition, as shown in Figure 4, when driving on an uneven road surface, the connecting part between the leading car and the sequentially connected connected cars can rotate in the vertical direction, so even in this case, smooth driving can be achieved. It can be performed.

(Effects of the Invention) Since the motorized articulated vehicle of the present invention is configured as described above, that is, the frame of the leading vehicle is provided with wheels, a power device for rotationally driving the wheels, a seat, a handle, and a brake, respectively. The front end of the frame of a connected car, which has wheels, a handle, and a seat, respectively, is connected to the rear end of the frame so that it can rotate horizontally and vertically, making it easy to drive the leading car and each connected car. If everyone is willing to do the same, it will be possible to drive around curves smoothly.
If everyone is not on the same page, that is, if even one person does not turn the steering wheel or turns the steering wheel in the opposite direction, the vehicle cannot run smoothly. Therefore, this motorized articulated vehicle can foster teamwork while having fun. In addition, when driving on uneven roads, the connection between the lead car and the connected cars that connect to it in turn rotates vertically, so if everyone is motivated, the cars can run smoothly even on uneven roads. It is a very fun vehicle.

In addition, the connection between the leading car and the connected cars connected sequentially to it is as follows:
By pulling out the pivot shaft inserted into the connecting portion, the leading car and each connected car can be easily disassembled individually, making operation easy.
