Hereinafter will be described in detail the effect of the bicycle having an upright steering wheel according to a preferred embodiment of the present invention.

The bicycle having the upright steering wheel according to the preferred embodiment of the present invention controls the driving while operating the first brake levers while holding the first steering handles with both hands when driving in an upright state. When the respective first brake levers are pulled, the first brake pad device connected to each of the brakes rubs against the front wheels or the rear wheels.

In addition, when sitting in the saddle to drive, the bicycle is operated by manipulating the second steering knobs and the second brake lever installed on the crossbar below the steering frame.

12 is a state diagram of use of a bicycle having an upright steering wheel according to a preferred embodiment of the present invention. As shown in FIG. 12, the driver may travel in a state in which the arm is extended forward in the standing state of the bicycle according to the present invention. Since the steering knob 35 is located at about the shoulder height, the driver runs with the shoulders straight in a state where the waist is opened.

The steering rod uses the word rod but refers to a rod-shaped member having various lengths that are not limited to the shape of the cross section.

The coupling of the steering rod and the coupling of the reinforcement can be welded or bolted.

In the embodiment shown in Figure 2 of the present invention, but the lower end of the steering rod adopts a configuration in which the bolt is fixed to the crossbar, it is also possible to fix by welding.

In the embodiment of the present invention, the saddle is provided, but the present invention is not limited thereto.

Since the brake pad devices are fixed to the steering shaft, the bicycle of the present invention does not require a separate configuration for installing a plurality of brake pad devices, thereby reducing costs and lighter weight.

The steering rods are equipped with rubber grips on the upper and lower parts of the steering wheel, so that the upper and lower parts of the steering wheel can be held by hand without slipping. To move the steering wheel on the rung.

Although the steering rod of the present invention adopts an integrated structure over the entire length, it is also possible to adopt a folding structure to form a hinge structure at a predetermined portion to fix the link when used and to fold and store the link when not in use. On the other hand, if a plurality of pipes with different outer diameters are fitted together to form a steering rod, when driving, a pipe with a small outer diameter can be pulled out of the large outer diameter pipe to make the steering rod longer and the bicycle can be stored. In this case, the pipe having a small outer diameter can be inserted inside the pipe having a large outer diameter to reduce its size.

Since the steering rods and the reinforcing arms of the present invention adopt a structure that is joined by mutual fitting, even if there is a certain error between the parts to be joined, the parts to be joined can be aligned and combined by applying elastic deformation. Assembly is easy.

Steering knobs installed on steering rods formed upright can operate in a position similar to grabbing ski poles, making it easier for the operator to operate the brake lever while standing.

The installation of two brake pads on each wheel takes into consideration both driving in a standing position and driving in a sitting position, and adopts the cheapest means for braking on both sides.

The structure in which the steering frame is formed by bending a single pipe has fewer joints, which reduces assembly effort and prevents the strength of the joint from weakening.

The steering rods are connected to each other at the top to prevent the steering rods from bending in the left and right directions.

In order to control steering accurately when driving in the standing state, the steering frame should be rotated in both directions with both hands, and in order to transmit sufficient turning force to the steering frame, the distance between the parts of the steering frame with handles will be about shoulder width. It is necessary.

The ring-shaped steering part also has a steering handle that is about the height of the shoulder when the driver is standing, so that the driver is comfortable while standing upright.

In the first embodiment of the present invention, a steering rod and a reinforcing frame and a brake pad device having a steering handle are detachable, but the present invention is not limited thereto. It is also possible to form the device to be integrally fixed to the bicycle.

The bicycle according to the fourth embodiment of the present invention adopts a structure in which the annular steering frames having a steering handle are integrally fixed to the bicycle. However, the present invention is not limited thereto, and the annular steering frame is the same as the bicycle of the first embodiment. It is also possible to combine the removable means such as the crosspiece of the bicycle through the coupling means. Such coupling means may be the same or similar to the coupling means used in the steering rod and the reinforcement frame in the first embodiment. In addition, since the brake pad device connected to the brake lever of the detachable steering frame is also detachable, the steering frame and the brake pad device may be combined with a general bicycle.

In the bicycle of the present invention, since the reinforcing frame supporting the steering rod is installed, the reinforcing frame assists the torsional load in the front and rear direction acting on the steering rod. Therefore, the torsion loads generated in the front and rear directions of the steering rods are applied to prevent the steering rods from being damaged.

Since the third type of the reinforcement has a structure in which one side is supported in the center of the front wheel, the reinforcement can be erected vertically, so that the load acting by the steering rod is mostly acted in the axial direction of the reinforcement and does not act as a torsional load. Because of this, the steering rod is more reliably reinforced. In addition, the shock absorber is provided in the reinforcement portion so that the elastic deformation in the longitudinal direction does not interfere with the function of the shock absorber formed on the steering shaft, and the two shock absorbers function more effectively.

According to the bicycle having the upright steering wheel according to the preferred embodiment of the present invention having the above-described configuration, the steering wheel is extended upward, and thus the driver can operate the bicycle in a standing state.

In the bicycle of the present invention, since the user runs in an upright position, the amount of exercise applied to the lower body even when traveling for a short time has a great effect of greatly developing the lower extremity muscle of the leg.

You'll feel like you're skiing on the road because you're driving in an upright position you never thought of on a bike. In particular, you can feel the thrill of skiing as you do not have to step on the downhill slope where you do not have to pedal for acceleration.

Unlike a conventional bicycle, the bicycle of the present invention has a steering rod that extends to the shoulder height and a handle is formed on the steering rod, so that the waist is always straightened even when the pedal is stepped up so that the burden is not burdened on the waist. It does not have the effect of running for a long time standing up.

Since the bicycle of the present invention runs in a state where the upper body is not prone forward, the neck is not tilted back when the front of the vehicle is driven, so that the neck is not burdened even when the bicycle is run for a long time.

In addition, since the handle including the brake lever is formed on the steering rod extending upward, there is no problem in adjusting the direction or speed freely.

In the present invention, it is possible to saddle, so in this case, it is possible to drive upright with the above-mentioned advantages, and there is a remarkable effect of simultaneously satisfying two functions that the user may select to sit and drive.

The bicycle of the present invention prevents the steering rod from being damaged by forming a reinforcing frame such that the steering rod is not bent by a load generated when the user's arm pushes the steering rod upright or pulls it backward.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it is possible to make various modifications or variations without departing from the spirit and scope of the invention. Accordingly, the appended claims will cover such modifications and variations as fall within the spirit of the invention.
