Bicycle is a means of movement that can be moved by rotating the pedal to obtain a driving force. In recent years, the use of bicycles is increasing for the purpose of exercise and leisure activities rather than the means of transportation, regardless of gender and age.

However, a general two-wheeled bicycle may be injured when the elderly or children run. To solve this problem, tricycles are being used.

However, the three-wheeled bicycle has a problem that the bicycle does not run stably because the pair of front wheels do not correspond to the steering direction when the user changes the steering wheel direction for steering on the curve road. That is, in the case of two-wheeled bicycle, the front and rear wheels can be tilted with respect to the ground as the user biases the body in the curve direction, and the two-wheeled bicycle can be driven stably. There was an unstable problem.

In addition, even when the front wheel is tilted, since the user must apply the load to the left and right, there is a problem that the tilting is not performed smoothly because it is difficult to move the body during driving. In addition, even when the front wheel is tilted, only the front wheel is tilted, and the seat and the frame in which the user is seated are not tilted.

On the other hand, the three-wheeled bicycle is capable of stable running compared to the two-wheeled bicycle, but has a disadvantage in that the overall volume is inconvenient to carry and store.

It is an object of the present invention to solve the above problems and to provide a reverse three-wheeled bicycle that can easily tilt the front wheel and the frame together while driving by changing the steering direction.

In addition, another object of the present invention is to provide a reverse three-wheeled bicycle that can be easily folded frame to facilitate the carrying and storage of the user.

It characterized in that it comprises a tilting transmission link to be.

According to one embodiment, the tilting transfer ring may be mutually coupled by a ball coupling link and a ball joint coupled to the steering rod receiving frame.

As shown in FIG. 3, the steering tilt transmission unit 400 according to the present invention includes a first front wheel coupling bar 410 and a second front wheel coupling bar that are coupled to the front wheel shafts 211 and 221 of the pair of front wheels 210 and 220. 420 and the upper horizontal coupling bar 430 and the lower horizontal coupling bar 440 which interconnects a pair of front wheel coupling bars 410 and 420 and transmits a steering direction of the steering rod 310 and the steering rod receiving frame Receiving frame coupling portion 450 is connected to the 330.

The first front wheel coupling bar 410 and the second front wheel coupling bar 420 are provided to have a predetermined length and are coupled in a direction perpendicular to the first front wheel shaft 211 and the second front wheel shaft 221. The pair of front wheel coupling bars 410 and 420 receives the steering direction from the upper horizontal coupling bar 430 and the lower horizontal coupling bar 440 so that the pair of front wheel shafts 211 and 221 are steered in the steering direction.

The upper horizontal coupling bar 430 and the lower horizontal coupling bar 440 is coupled to the lower region of the steering rod 310, a pair of front wheel coupling bars (410, 420) coupled to both ends of the steering direction of the steering rod 310 To pass.

Here, the upper horizontal coupling bar 430 is provided with a tilting transmission link (431). The tilting transmission link 431 is coupled in a direction perpendicular to the upper horizontal coupling bar 430 through a pair of fixed links 433. The transfer ball joint 431a is provided at an end region of the tilting transmission link 431.

The receiving frame coupling part 450 is coupled to one side of the steering rod receiving frame 330. The accommodating frame coupling part 450 is provided with a ball coupling link 455.

When the user rotates the steering rod 310 to change the steering direction, the position of the steering rod accommodation frame 330 is fixed. Therefore, the position of the ball coupling link 455 coupled to the steering rod receiving frame 330 side is fixed. On the other hand, the tilting transmission link 431 coupled to the steering rod 310 side is moved by the steering angle of the steering rod 310.

By the joint coupling of the ball joint 455a and the transfer ball joint 431a, the tilting transmission link 431 is eccentric by the tilting angle and tilted at an angle with respect to the axial direction. When the tilting transmission link 431 is tilted, the tilting angle is transmitted to the upper horizontal coupling bar 430 supporting the tilting transmission link 431, and the front wheel coupling bars 410 and 420 mutually coupled with the upper horizontal coupling bar 430. Delivered. Therefore, the pair of front wheels 210 and 220 are also inclined by the tilting angle.

4 to 7 are exemplary views showing a tilting process of the reverse three-wheeled front wheel bicycle 10 according to the present invention.

As shown in FIG. 4, when the user rotates the steering rod 310 in the clockwise direction, the upper horizontal coupling bar 430 and the lower horizontal coupling bar 440 directly coupled to the steering rod 310 are the steering rod 310. The steering angle of is rotated by. When the upper horizontal coupling bar 430 and the lower horizontal coupling bar 440 is rotated, the front wheel coupling bars 410 and 420 coupled to both ends thereof are also rotated by a steering angle. Accordingly, the front wheels 210 and 220 coupled to the front wheel coupling bars 410 and 420 also rotate by the steering angle and the steering direction is changed.

On the other hand, when the steering rod 310 is rotated in the clockwise direction, as shown in Figure 5, the position of the upper horizontal coupling bar 430 is moved from the axial direction to the right by the steering angle. At this time, since the position of the steering rod receiving frame 330 accommodating the steering rod 310 does not change, the positions of the ball coupling link 455 and the ball joint 455a are the same as before the steering direction is changed.

The tilting transmission link 431 has the same position as that of the transfer ball joint 431a coupled with the ball coupling link 455 and the lower region coupled with the upper horizontal coupling bar 430 is moved to the right as before the steering direction is changed. Therefore, the axis of the tilting transmission link 431 is rotated by a certain angle (a) with respect to the central axis.

As shown in FIG. 6, when the tilting transmission link 431 is inclined, the upper horizontal coupling bar 430 and the lower horizontal coupling bar 440 supporting the tilting transmission link 431 also rotate the rotation angle of the tilting transmission link 431. (a) is inclined relative to the ground, and the inclination angles of the upper horizontal coupling bar 430 and the lower horizontal coupling bar 440 are transmitted to the front wheels 210 and 220 through the front wheel coupling bars 410 and 420. Therefore, the pair of front wheels 210 and 220 are also tilted and tilted with respect to the ground by the rotation angle a.

That is, in the reverse three-wheeled bicycle 10 according to the present invention, the steering direction of the front wheels 210 and 220 is changed according to the steering direction of the steering rod 310 and the front wheels 210 and 220 are changed according to the rotation angle of the tilting transmission link 431.

As shown, when the steering rod 310 is rotated in the counterclockwise direction, the pair of front wheels 210 and 220 are changed in the steering direction in the counterclockwise direction, and the tilting transmission link 431 is in the steering direction of the steering rod 310. Accordingly, the pair of front wheels 210 and 220 are tilted relative to the ground by a predetermined angle a while being rotated counterclockwise.

Here, the elastic member 460 included in the steering tilt transmission unit 400 acts an elastic force to maintain the standing tricycle 10 in the standing position in the initial position does not change the steering direction. The reverse tricycle 10 according to the present invention is steered by wind or external force in a state in which the user stands up without driving the reverse tricycle 10 because the front wheels 210 and 220 are tilted when the steering direction of the steering rod 310 is changed. If the direction changes, it is difficult to maintain the standing position.

The elastic member 460 imparts an elastic force so that the reverse tricycle 10 maintains the standing state in a state where the elastic member 460 is not traveling. Since the elastic member 460 only serves to maintain the standing state, the elastic member 460 preferably has an elastic force such that interference does not occur when the user applies an external force to change the steering direction.

The elastic member 460 is coupled to the upper region of the upper horizontal coupling bar 430, the lower region is coupled to the lower region of the steering rod (310). When the external force is applied to the steering rod 310 in the standing state, the elastic member 460 applies an elastic force to maintain the initial state in which the steering rod 310 is located at the center, and the user has an external force beyond the elastic force of the elastic member 460. To change the steering direction.

The rear wheel part 500 supports the rear wheel 510 to be rotatable with respect to the frame 100. The rear wheel part 500 includes a rear wheel 510 for generating a driving force, a rear wheel rotation shaft 520 for supporting the rear wheel 510 to be rotated, and one end of the rear wheel rotation shaft 520, and the steering part 300 and the seat. The rear wheel chain gear 530 receives a driving force by the driving chain 640 during driving by the unit 500.

The driving unit 600 generates a driving force on the rear wheel 510 to allow the reverse three-wheeled bicycle 10 to move. The driving unit 600 according to the present invention generates a driving force by the rotation of the pedal 610. The driving unit 600 includes a pair of pedals 610, a pedal shaft 620 for rotatably supporting the pedal 610, a pedal gear 630 coupled to the pedal shaft 620, and a pedal gear 630. Pedal chain 640 to transmit the rotation of the rear wheel 510. The pedal chain 640 is coupled to the pedal gear 630 and the rear wheel chain gear 530 of the rear wheel 510.

In the driving unit 600, the pedal gear 630 is rotated by the rotation of the pedal 610, the pedal chain 640 is rotated by the rotation of the pedal gear 630, and generates a driving force to the rear wheel 510.

Hereinafter, a folding process of the reverse tricycle 10 according to the present invention will be described with reference to FIGS. 8 to 11.

The user unlocks the locking lever 130 when the user wants to reduce the volume for storing or transporting the bicycle after using the reverse three-wheeled bicycle 10. As a result, the first moving frame 113 and the second moving frame 115 fixed to the guide frame 111 can be moved.

In this state, when the user presses the first moving frame 113 and the second moving frame 115 upward, as shown in FIG. 9, the first moving frame 113 and the second moving frame together with the lever shaft 131. The moving frame 115 moves along the guide rail 111c and is lifted. As the first moving frame 113, the second moving frame 115, and the guide frame 111 are moved, the fixed frame 120 is also bent in a 90 degree direction from the initial position.

As shown in FIG. 10, when the first moving frame 113 and the second moving frame 115 are positioned at opposite ends of the guide rail 111c, the fixed frame 120 is folded and folded and the front wheels 210 and 220 are rotated. The rear wheel 510 is in contact with each other.

When the folding is completed and the volume is minimized, the locking lever 130 is locked to maintain the folded state.

That is, the reverse three-wheeled bicycle 10 according to the present invention releases the locking lever 130 and is easily folded by the user pressing the first moving frame 113 and the second moving frame 115 upward. Volume can be minimized. In addition, since the guide rail 111c guides the folding process in the folding process, the folding may be stably performed.

As described above, the reverse three-wheeled bicycle according to the present invention may not only change the steering angle of the pair of front wheels according to the change of the steering direction, but also adjust the tilting angle of the pair of front wheels and the frame. Accordingly, the steering angle and the tinting angle can be conveniently adjusted while driving, and the tilting effect can be further increased because the front wheel and the frame are tilted together.

In addition, the frame can be mutually folded and the volume can be minimized by the two operations of unlocking the locking lever and pressing in the upward direction, thereby increasing user's convenience.

The embodiment of the reverse three-wheeled bicycle of the present invention described above is merely illustrative, and those skilled in the art will appreciate that various modifications and equivalent other embodiments are possible therefrom. Could be. Therefore, it will be understood that the present invention is not limited only to the form mentioned in the above detailed description. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
