Abstract
Description
[Technical field]
[0001] The present invention relates to a bicycle that allows a rider to ride and pedal in any direction, north, south, east or west, relative to the direction of travel. [Background technology]
[0002] Traditionally, bicycles were ridden facing forward and moved forward. This is common sense, and in order to ensure safety, it is necessary to keep one's eyes on the road when riding, so bicycles ridden facing in any other direction were almost unheard of, except for those used for performances and acrobatics. Summary of the Invention [Problem to be solved by the invention]
[0003] As mentioned above, this invention was made to realize a bicycle that the rider can ride facing in any direction, something that had not been paid much attention to or existed until now. The rider of the bicycle can ride in a natural posture by fixing the riding frame, which has the saddle and pedals, to the body so that it faces in any direction of the riding direction relative to the direction of travel.
[0004] For example, when riding facing west with the direction of travel being north, if the riding frame is attached to the vehicle body facing west, the saddle and pedals will face west, allowing you to ride facing west and travel north. [Means for solving the problem]
[0005] The vehicle is separated into a riding drive frame, which is the drive system in which a driver rides and pedals to generate driving force, and a vehicle body, which is the driven system that supports the axle to which the wheels are connected, and both are fixedly connected to each other so as to be rotatable in the desired direction on a vertical axis.
[0006] The riding drive frame has a saddle, supports the pedal shaft, and supports a vertical rotation shaft whose rotation is converted to vertical rotation by an orthogonal gear. The lower part of the frame has a connection part for connection to the vehicle body.
[0007] The pedal shaft of the riding drive frame and the axle of the vehicle body are horizontal shafts, and the riding drive frame and the vehicle body are rotatably connected to a vertical shaft. Therefore, by converting the horizontal rotation of the pedal shaft into vertical rotation inside the riding drive frame and supporting it as a vertical rotating shaft, it becomes possible to transmit rotation even when the vehicle is rotatably attached to a vertical shaft relative to the vehicle body. The rotation of this vertical rotating shaft is further converted into horizontal rotation by an orthogonal gear and transmitted to the axle of the vehicle body to rotate the wheels and move the vehicle.
[0008] This allows the two to be connected freely rotatably around the vertical axis of rotation, so that a rider on the riding frame can face in any direction and pedal in that direction to build a bicycle that travels in the desired direction. Effect of the Invention
[0009] Depending on the purpose of the bicycle, it is easy to make bicycles that can be ridden forward or sideways. It will be usable for a variety of purposes, including agriculture and tourism.
[0010] When used for agricultural purposes, the driver can ride sideways and move along the ridges while picking fruit. When used for construction work, the driver can move forward while carrying out construction work, which dramatically improves work efficiency. In addition, when used for sightseeing, if bicycles are used in an ingenious way, such as by leaving a certain distance between bicycles on bicycle-only roads, it will be possible to cycle sideways while enjoying the scenery.
[0011] In addition, if the riding drive frame is attached to a ship with a propeller attached to the drive shaft, it can be used as a human-powered ship. If it is attached to an aircraft, it can be used as a human-powered airplane. In addition, it has the potential to be used in a dramatically expanded range of fields as an innovative pedal-powered self-propelled vehicle in different environments than conventional ones.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0013] An embodiment in which the present invention is applied to a four-wheeled bicycle will be described below with reference to the drawings. The riding drive frame 100 is equipped with a pedal drive system consisting of a pedal 220, a pedal rod 210, and a pedal shaft 200, and this pedal shaft 200 is supported horizontally.
[0014] The horizontal rotation of the pedal shaft 200 is converted into vertical rotation by the pedal shaft orthogonal gear 230 and transmitted to the vertical rotation shaft 240, which is supported vertically by the vertical bearing 140.
[0015] A drive axle 320 having wheels 350 at both ends is supported by axle bearings 315 on the vehicle body 300 , and vertical rotational force is transmitted via a vehicle body orthogonal gear 330 .
[0016] When connecting and fixing the riding drive frame 100 and the body 300, the coupler 245 of the vertical drive shaft 240 and the body orthogonal gear vertical shaft 340 are connected to enable the rotational force of the pedal shaft 220 to be transmitted to the axle 350, and the body fixing hole 385 of the body fixing frame 380 and the riding drive frame fixing hole 185 are aligned and attached.
[0017] When installing the seat, you can choose to ride sideways or forward, and then secure the seat in place with screws.
[0018] As explained above, the rider H riding on the saddle 190 can ride and ride freely either facing forward or sideways relative to the vehicle body 300. However, by increasing the number of mounting holes, the riding direction can be selected from a wider range of fixed directions, such as diagonally sideways or diagonally forward.
[0019] Whether the driver H faces forward in the direction of travel and pedals the pedals 220 as shown in FIG. 3, or faces sideways as shown in FIG. 4, the horizontal rotation of the pedal shaft 220 is converted into vertical rotation by the double orthogonal gears 230, and then converted back into horizontal rotation by the body orthogonal gear 330 of the body 300 connected in the desired direction. The rotation is then transmitted to the axle 320 to rotate the wheels 350, allowing the vehicle to travel without any hindrance.
[0020] When the user wishes to change the direction of travel, the auxiliary wheels 360 can be operated to change their angle and change direction in any direction.
[0021] The above explanation has been given of an embodiment using a conventional bicycle in which the pedals 220 are rotated, but by providing a free hub 280 inside the left and right pedal bars 210 as shown in FIG. 5 and utilizing a means (known means) for converting the reciprocating motion of the pedals 220 into continuous rotation, it is possible to obtain continuous driving force by reciprocating both pedals, so that the vertical stroke of both pedals 220 can be made small and the rider H can ride at a lower position closer to the ground, making it possible to construct an even more user-friendly work bicycle.
[0022] Since the riding drive frame 100 can be used as a single component as a drive module, it can be attached to various vehicles. For example, if it is used in a boat with a propeller attached to the drive shaft, it can be used as a human-powered boat, and if it is used in an airplane, it can be used as a human-powered airplane.
