Abstract
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bicycle, and more particularly, to a bicycle that is capable of low power and excellent in portability when a user uses and carries a bicycle.
Description
BACKGROUND OF THE
1A is unstable because there is no or insufficient means to steer only the front wheels separately; FIG. 1B is a publication No. 16444 (2001.03.05), in which there is no means to be a support point for the steering when attempting to steer the front wheels, so that there is no choice but to twist the whole body or use recoil. Steering is difficult if not (user); FIG. 1C is a Korean Utility Model No.19682 (September 23, 1993). The steering wheel can be steered by the saddle support point, but at the same time, the power system such as a pedal rotates left and right along the steering wheel. It is difficult to continuously touch the user's foot to the pedal and to transmit an effective force in a direction that is displaced.
In particular, if the steering angle is large, it is impossible to press the pedal itself.
The present invention minimizes the structure of the bicycle body (frame), reduces weight, and uses less force in use and transportation; Maximizes portability by achieving minimum volume; At the same time comfortably position the pedaling foot; Do it.
Front wheel stem; A saddle provided at an upper end of the front wheel stem; A front wheel provided at a lower end of the front wheel stem; A driving unit for driving the front wheels; A front wheel part comprising: a handle part including a handle stem provided between the saddle and the front wheel stem and a handle provided at a front end of the handle stem;
Rear wheel stem; A steering shaft support receiving the front wheel stem on an upper end of the rear wheel stem; Consists of a rear wheel portion including; the rear wheel provided at the bottom of the rear wheel stem,
Manipulating the handle is configured to turn the handle portion from side to side.
Further, when the handle is operated, the front wheel portion is configured to steer the steering shaft support as a shaft.
Alternatively, the handle stem may be installed on the front wheel stem and the steering shaft bearing of the rear wheel stem may receive the rear end of the handle stem to be a steering shaft.
According to the present invention,
The structure of the bicycle body is minimized; Lightweight and easy to use and carry; Can be achieved in a minimum volume to enhance portability; Comfortable position of the pedaling foot; It can enhance the convenience for the user and contribute to the expansion of the bicycle base.
In the case of a conventional all-wheel drive bicycle, when the front wheels change direction, the crank pedals must be switched in the same direction to avoid collision with the crank pedals. Bar eliminates these shortcomings.
In the present invention, the scope includes the other embodiments including the technical spirit of the present invention in addition to the illustrated embodiments.

In addition, the bevel gear can be replaced by other known combinations of gears, other mechanical elements, such as a friction difference. In other words, if the mechanical element that transmits the rotation (including diffraction) to the forward and reverse, or change the direction of the other angle to transmit the transmission, other known and common, including the common one can be used in the above configuration of the present invention and this element in the present invention Is called the steering operation transmission element.
On the other hand, the angle of the axis of the
Or fix the position of the saddle forward or rearward to match the ground point of the handle stem and the front wheel; As shown in FIG. 21 (A), the front wheel stem 110 may be bent to fold the folding means 170, and the rotation shaft of the front wheel stem and the saddle may coincide.
Here, the above-described configuration methods may be used for other purposes in addition to the case of matching the rotation axis of the saddle with the front wheel ground point.
Conversely, the rotation axis of the saddle and the rotation axis of the front wheel grounding point can be configured as a part, for convenience of configuration of the present invention; Give the caster angle to the front wheels; When the user's body leans forward when riding, the center of gravity of the user is formed in front so that the center of gravity is closer to the rotation axis to adapt to this; For convenience of steering operation; Affect the steering rotation of the handle stem through the weight of the user; Aesthetic appearance; For such purposes.
In FIG. 21 (B), the front wheel stem is divided into two parts and provided so that the folding means 170 can be formed by inserting the handle stem therebetween. It can also be inserted in between.
FIG. 22 exemplifies various types of handle stems and steering operation means, and FIG. 22 (A, C) shows a case in which a bevel gear (or material joint) is added to the rotation shaft of the
As shown in FIG. 16 (B, C), by disassembling and assembling each part, convenience of maintenance, storage, and transportation can be improved.
For all components, such as the steering control means 150, more specific details or those of other methods in addition to the above-mentioned configuration refers to those illustrated in Figs.
