[0002]
2. Description of the Related Art Conventionally, a hand-held unicycle, which is commonly called a cat car, is well known as a transportation device for materials, agricultural products, and the like, and is particularly useful for traveling in a narrow place.
[0003] When carrying large loads, heavy loads, or the like, a hand-held motorcycle that can easily maintain the balance of the vehicle body during traveling may be used.
[0004]
[Problems to be solved by the invention]
However, according to the above prior art, when traveling with loaded luggage as a problem of the unicycle, maintaining a balance of the vehicle body requires some skill and physical strength, so that a person who is unfamiliar with the operation or a woman or a person with weak physical strength It is unsuitable for humans, and is particularly remarkable when there is a large difference between the load center and the wheel contact surface, or on a rough road having a slope or unevenness.
A motorcycle is known as a means for compensating for the disadvantages inherent in a unicycle, in which it is difficult to maintain the balance of the body, but the motorcycle is inclined to the left or right with respect to the traveling or reversing direction, or on a rough road having irregularities. There was a danger of collapse, falling of the load, etc., and when liquid, powder, sludge, etc. were full, spillage and scattering in the passage were likely to occur.
Accordingly, an object of the present invention is to provide a hand-held type motorcycle that is easy to handle, safe, and has good running stability, even for a person who is unfamiliar with operation or a woman or a person with weak physical strength.
[0007]
[Means for Solving the Problems]
In order to solve the above problems, the invention according to claim 1 is provided with a bed rotating mechanism between a single-axle two-wheeled truck with good running stability and a bed, and the two arms of the operator to be added to the steering handle. A hand-carrying motorcycle characterized in that the loading platform can be leveled or tilted by adjusting the force.
According to a second aspect of the present invention, there is provided a two-wheeled vehicle having a carrier rotation suppressing plate which is fixed to a bogie to suppress the rotation of the carrier. A push function characterized by being able to arbitrarily select a function capable of arbitrarily selecting a function capable of horizontally or inclining the bed by adjusting the force of the two arms of the operator applied to the steering handle by holding the restraining plate in a free state without fixing. It is a motorcycle.
According to a third aspect of the present invention, there is provided a hand-operated two-wheeled vehicle having a function of adjusting a mounting width of a pair of wheels disposed on the same shaft depending on a use condition.
[0010]
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. 1 is a side external view of a hand-held motorcycle of the present invention, FIG. 2 is a front external view, FIG. 3 is a schematic diagram of a bed rotation suppressing mechanism, and FIGS. 4 and 5 are schematic diagrams of wheel width adjustment. It is.
The mounting portion of the loading tray 21 and the handle portion 9 are fixed to the loading frame 2 formed by bending an iron pipe, and the loading tray 21 is fixed to the loading frame 21 with a fastener (not shown). Collars 8, 8 for connecting to the truck are suspended via the iron pipes 7, 7, and a carrier rotation inhibiting plate 11 for suppressing the platform rotating function is provided at the rear center of the carrier. The mounting brackets 5a and 5b of the stand 4 are suspended from each other to form a carrier.
At the center of the bogie frame 10, bearing plates 14, 14 of the loading platform rotating fulcrum shaft 13 hang down. On both sides of the bogie frame 10, wheel support frames 15, 15 integrated with the wheel bearing plates 16, 16 hang down. The rotatable wheels 17, 17 form a bogie portion with a structure fixed to a wheel shaft 18 inserted through the wheel bearing plates 16, 16 by a plurality of wheel width adjusting cylinders 19.
A pair of stands 4 used for locking the motorcycle is fixed to the stand mounting brackets 5a, 5b by bolts 6a, 6b, but has a structure in which the bolts 6a, 6b can be loosened and removed. .
When the vehicle travels on a flat passage or when carrying a small volume or heavy object which does not have the danger of collapse or falling off even if the carrier is inclined, the carrier rotation inhibiting plate 11 for suppressing the carrier rotation function is fixed by bolts 12. By fixing to the carriage, the carriage and the carrier are integrated, the load on both arms of the operator is reduced, and more stable traveling is possible.
FIG. 4 shows a state in which the wheel width suitable for traveling on a narrow passage is narrowed.
FIG. 5 shows a state in which a wheel width suitable for loading and running a wide passage or a heavy object, a baggage having a high center of gravity, or a baggage whose center of gravity is largely shifted left and right is set. is there.
[0017]
FIG. 6 shows that in a passage inclined to the left and right with respect to the traveling direction, the two arms 20a and 20b of the operator (not shown) act on the steering handles 9 and 9 in the direction of the vertical arrows to adjust the right and left arms. In this state, the loading platform is rotated in a circular direction about the rotation fulcrum shaft 13 as a fulcrum and is kept horizontal.
FIG. 7 shows an embodiment in which the luggage carrier 1, the carriage 3 and the pair of stands 4 are separately housed, which saves space and contributes to a reduction in logistics costs on the manufacturing and sales routes. Space can be reduced.
[0019]
As described above, according to the present invention, by rotating the carrier with the carrier rotating fulcrum axis of the carrier rotating mechanism as a fulcrum, even if the truck is inclined on a rough or uneven road, It is possible to keep the loading platform horizontal with human power, avoiding dangers such as collapse of the load, falling of the load, spilling of the load, and by setting the wheel width according to the use situation, people who are unfamiliar with operation or women and Stable driving is possible even for people with weak physical strength.
When the vehicle is traveling on a flat passage, or when transporting a small volume or a heavy object or the like where there is no danger of collapse or falling off even if the carrier is tilted, the carrier rotation restraining plate is fixed to the carrier with bolts, and the carrier rotating mechanism is operated. By suppressing the load, the burden on the operator's arm is reduced, and more stable driving is possible.
In the present embodiment, the platform rotation inhibiting plate is fixed to the platform with bolts. However, the platform can be easily developed into a simple operation type such as a pin insertion type or a lever hook type.
It has a function of easily disassembling and assembling a carrier, a trolley and a stand, so that it is possible to reduce logistics costs on manufacturing and sales routes and reduce storage space for users.
