As shown in FIG. 1, the bicycle 10 includes a front wheel 20 having steering characteristics, a rear wheel 30 for driving, a handlebar 40 for steering by a driver according to a driving direction, and a handlebar 40. The brake lever 50 and the front wheel 20 and the rear wheel 30 are rotatably mounted on the left and right ends of the frame 60 and the saddle 61 is mounted to allow the driver to sit. In addition to the brake arms 70a and 70b respectively mounted to the 20 and the rear wheel 30 to control the rotation of the wheels, other components are included.

The brake device of the bicycle configured as described above will be described in detail.

1 and 2, a pair of brake arms 70a and 70b are hinged to the frame 60 at both sides of the front wheel 20, respectively. The brake pads 71 are fixed to the inner surfaces of the pair of brake arms 70a and 70b, and when the pair of brake arms 70a and 70b are turned in a close direction, the brake pads 71 are moved to the front wheels 20. The rim 21 is pressed and braked by the friction between the brake pad 71 and the rim 21.

Meanwhile, as shown in FIG. 3, the brake lever 50 is mounted at the left end of the handle bar 40. One end of the first cable 80 is fixed to the bracket 51 of the brake lever 50, and the first wire 81 located inside the first cable 80 is fixed to the brake lever 50. Therefore, when the driver grips the handle bar 40 and the brake lever 50 together, the brake lever 50 is pivoted and the first wire 81 embedded in the first cable 80 is pulled.

The other end of the first cable 80 is fixed to a bracket 73 mounted on one of the brake arms 70a of the pair of brake arms 70a and 70b hinged to both sides of the front wheel 20, respectively. do. The first wire 81 embedded in the first cable 80 is fixed to the other brake arm 70b.

In such a structure of the braking device, when the driver grabs the brake lever 50, the first wire 81 is pulled by the turning of the brake lever 50, and thus the pair of brake arms 70a and 70b. The brake pad 71 pressurizes and brakes the rim 21 of the front wheel 20 while turning in a direction approaching each other.

When the driver releases the brake lever 50 held by the driver, the force pulling the first wire 81 is released, and the elasticity of the torsion spring (not shown in the figure) built in the pair of brake arms 70a and 70b is released. Turn in the direction of mutual expansion by the restoring force.

The rear wheel 30 of the bicycle is also the same as the structure of the front wheel brake device 20 described above, the brake lever for the rear wheel brake operation is mounted on the right end of the handle bar.

And, as shown in Figure 4, the stand 90 is mounted on the outer side of the frame 60 corresponding to the rear wheel 30. When the bicycle 10 is parked, the bicycle is erected by forming one contact point by the stand 90 in addition to the two contacts of the front wheel 20 and the rear wheel 30 contacting the ground. Such a stand is laid flat in the horizontal direction when driving, and is in contact with the ground while standing when parking.

However, when the bicycle is parked on the slope, the front wheel, the rear wheel and the stand alone cannot stand the bicycle. The reason is that the steering front wheel is biased by the inclined surface and naturally turns in the biased direction, that is, the downward direction. And the front wheel is rolled as the inclination direction of the ground and the direction of the front wheel gradually coincide, and as the front wheel with steering rolls downward, the entire direction of the bicycle is turned downward.

In this case, the rear wheel tries to maintain the standing state on the stand, but if the front wheel is rotated while the direction of the front wheel is turned downward, the bicycle is rolled downward by the rotation of the front wheel and the inclination angle of the ground.

In most cases, the bike's direction is twisted downwards, causing it to lose its center of gravity and fall over before rolling.

Recently, various accessories and safety tools for driving the bicycle are mounted on the bicycle. In particular, for long-distance bicycle driving, expensive GPS equipment may be mounted on the bicycle. In addition, many expensive bicycles are being produced.

However, when the bicycle falls, such expensive bicycles and expensive equipment are damaged, and when the bicycle falls, a person may hit a person and cause a safety accident.

In addition, when the driver parks the bicycle on a sloped slope, the driver tries to park in consideration of the center of gravity and the inclination angle of the bicycle so that the bicycle does not fall or roll down.

In addition, even if the bicycle parked on a flat surface because the steering wheel is steered, if strong wind or shock is applied to the front wheel, the center of gravity of the front wheel is shifted, the bicycle easily falls.
