Description

Bicycle {BICYCLE}

The present invention relates to a bicycle, and more particularly, to a bicycle capable of a rearrangement and a rearrangement.

A bicycle is a transportation device that obtains power through a pedaling device that rotates through the user's vigor. Usually, the steering device is connected to the front wheel. That is, a steering wheel is provided on the upper part of the front wheel, and the steering shaft of the steering wheel and the steering shaft of the front wheel are integrally formed. When the user rotates the steering wheel by a certain angle, the front wheel rotates at a certain angle.

On the other hand, there is a bicycle in which the front wheel is steered in a direction opposite to the steering direction of the user in order to induce the user's interest and increase the commerciality.

Korean Utility Model Registration No. 20-0428483 (published on October 13, 2006, hereinafter referred to as "the present document") discloses a reverse handle bike. The bicycle of this document has a configuration capable of selectively adjusting the steering direction or the steering direction when the steering wheel is replaced with any one of the two front frames. More specifically, in the case of the tuning steering, the rotation of the steering wheel is directly transmitted to the steering shaft of the front wheel. In the case of the reverse steering, the direction of the steering wheel is changed through the gears, And is transmitted to the steering shaft of the front wheel.

However, such a bicycle has disadvantages in that, when the steering wheel is installed in the front frame and the steering direction is changed, the handle must be dismantled and then installed in another front frame.

In addition, since the steering shaft of the steering wheel is aligned with the steering shaft of the front wheel during reverse steering, the steering shaft of the steering wheel is separated from the steering shaft of the front wheel during reverse steering, There are different problems.

1 and 2, a bicycle 10 according to a preferred embodiment of the present invention includes a first switching box 100, a second switching box 200, a driving gear 300, An induction means 400, and a tidal-aroma inducing means 500.

The inverse steering refers to steering in which the rotational direction of the steering wheel 2 and the rotational direction of the front wheel steering shaft 1 are the same, Means that the rotational directions of the shafts 1 are opposite to each other.

The first switching box 100 and the second switching box 200 are formed in a box shape and form a space for accommodating the reverse steering induction means 400 and the decorating direction inducing means 500 therein. The first switching box 100 and the second switching box 200 may be slidably coupled to each other. To this end, a slide slot 120 may be formed on a side surface of the first switching box 100. When the user pushes the handle or the second switching box 200 forward, the second switching box 200 moves forward along the slide slot 120. On the other hand, a separate locking means may be added to prevent the second switching box 200 from moving.

In the first switching box 100, a front steering shaft 1 is rotatably engaged. To this end, a bearing (not shown) may be formed in the first switching box 100 to engage with the front steering shaft 1. [

And the steering wheel shaft 2 is rotatably coupled to the second switching box 200. At this time, the steering shaft 2 can be shiftably coupled to the second switching box 200 in the vertical direction.

The first switching box 100 and the second switching box 200 may be hermetically sealed so that rainwater or foreign matter does not enter the interior of the cradle inducing means 500 and the reverse steering inducing means 400.

Meanwhile, the first switching box 100 may be provided with a first cylindrical holder 110 into which the front wheel steering shaft 1 is rotatably inserted. The second switching box 200 may be provided with a second cylindrical holder 210 into which the steering shaft 2 is rotatably inserted. At this time, the second cylindrical holder 210 can be vertically shifted by a predetermined height in the second switching box 200.

The driving gear 300 is engaged with the end of the steering shaft 2 to transmit the rotational force of the user to the front wheel steering shaft 1. [ As the steering shaft 2 is shifted in the vertical direction, the driving gear 300 is also shifted in the vertical direction.

The reverse steering induction means 400 switches the steering wheel 2 in a direction opposite to the rotational direction of the steering wheel 2 and transmits the steering wheel to the front wheel steering shaft 1. The reverse steering induction means 400 may be a first driven gear 400 formed on the front wheel steering shaft 1. [ The first driven gear 400 meshes with the driving gear 300 to transmit the rotational force of the driving gear 300 to the front steering shaft 1. [ At this time, the gear ratio between the first driven gear 400 and the drive gear 300 may be 1: 1.

The tuning-aroma inducing means 500 switches to the same direction as the rotational direction of the steering wheel shaft 2 and transmits it to the front wheel steering shaft 1. [

The tuning-aroma induction means 500 may include a second driven gear 510 and a pinion gear 520. The second driven gear 510 is formed on the front wheel steering shaft 1 and can be installed directly below the first driven gear 400. The pinion gear 520 is arranged to engage with the second driven gear 510. The rotation axis 521 of the pinion gear 520 may be coupled to the first switching box 100. The pinion gear 520 meshes with the driving gear 300 to transmit the rotational force of the driving gear 300 to the second driven gear 510.

FIG. 4 is a diagram illustrating the movement of the first switching box and the second switching box during the steering mode change process.

Referring to Fig. 4, when changing from the inverse steering mode or the reverse steering mode to the inverse steering mode in the tuning direction mode, it is necessary to push the second switching box 200 forward or push it backward.

Hereinafter, the steering direction changing process will be described with reference to a process of changing from the inverse steering mode to the tuning direction mode.

Fig. 5 is a view showing the movement of the drive gear in the state of Fig. 4 (b).

4, the user pushes the handle or the second switching box 200 to shift the steering wheel shaft 2 forward as shown in Fig. 4 (a) to Fig. 4 (b) .

At this time, in the reverse steering mode, the driving gear 300 and the first driven gear 400 are engaged at the coupling reference plane P, but when the handle or the second switching box 200 is pushed, The state of engagement between the driving gear 300 and the first driven gear 400 is released as shown in Fig. 5 (b).
8, the engagement reference plane P is formed in a plane in which the teeth of the first driven gear 400 and the teeth of the gear of the drive gear 300 mesh with each other and the pinion gear 520, And the teeth of the gears of the driving gears 300 are in contact with each other and in contact with each other.

6 (a), when the user pushes down the steering wheel and shifts the steering wheel shaft 2 downward as shown in Fig. 4 (b) to Fig. 4 (c) The driving gear 300 is aligned with the height of the pinion gear 520 as shown in Fig. 6 (b).

Thereafter, when the user pushes the second switching box 200 backward, the drive gear 300 is shifted to the state shown in FIG. 6 (b) So that the rotational force of the driving gear 300 is transmitted to the front wheel steering shaft 1 via the pinion gear 520 and the second driven gear 510. [

Fig. 8 is a view showing a tilt direction mode and an inverse steering mode.

8, in the forward tilting mode, since the front wheel steering shaft 1 rotates in a direction opposite to the rotation direction of the steering shaft 2, the driving gear 300 is engaged with the first driven gear 400, The front wheel is rotated in a direction opposite to the rotation direction.

In the reverse steering mode, since the drive gear 300 is engaged with the pinion gear 520 and the pinion gear 520 is again engaged with the second driven gear 510, the same direction as the rotational direction of the steering wheel shaft 2 The front wheel steering shaft 1 is rotated, and the front wheel is rotated in the same direction as the rotational direction of the steering wheel.
