Description

Stunt Bike {ACROBATIC CYCLE}

The present invention relates to a stunt bike, and more particularly, to a stunt bike that the bicycle does not fall by overcoming the fundamental instability of the unicycle while utilizing the characteristics of the unicycle.

Referring to FIG. 1, in general, a unicycle is rotatably connected to a hub 5 of a wheel 1 on a frame 5, a shaft is fitted to the hub 2, and both ends of the shaft are pedals 4. ) Is connected, the pedal effort is transmitted to the hub of the wheel through the shaft, the wheel is advanced, the saddle bar of the saddle (3) is connected to the top of the frame (5).

The conventional unicycle as described above can fall 360 degrees in any direction, requiring skilled skills for boarding.

Accordingly, it is an object of the present invention to provide a stunt bike in which the bicycle does not fall by overcoming the fundamental instability of the unicycle while utilizing the characteristics of the unicycle.

Stunt bicycle according to the present invention for achieving the above object is that the unicycle is coupled to the auxiliary wheel device, the vertical frame of the unicycle through the square piping of the arch support for forming the auxiliary wheel device lower part of the auxiliary wheel device It is fitted to the vertical projections erected in the center of the support frame, characterized in that the support plate disposed on the lower vertical frame of the unicycle is supported by a spring mounted to the lower support frame of the auxiliary wheel device.

The unicycle has a vertical frame composed of a pair of square pipes, so that wheels can be rotated by pedals between the square pipes, two square pipe tops are connected by a connecting member, and the top of the square pipe is connected. In the state where the height adjustment of the saddle is fitted, the height adjustment of the saddle is fixed by a bolt fastened to the square pipe, characterized in that the braking device brakes the wheel by the brake lever mounted on the handle of the saddle.

The auxiliary wheel device is a lower support frame connecting the front caster and the rear caster is composed of a pair of pipes, a pair of flanges of the arch support is coupled to the lower support frame by the fastening means, and the flange of the arch support The spring is mounted on the spring mounting portion of the lower support frame so that the spring is disposed between the vertical protrusions formed in the center of the lower support frame.

Thereby, the stunt bike according to the present invention can easily ride a beginner while taking advantage of the unicycle, and the shock is buffered by the spring.

Figure 2 is a perspective view of the stunt bike according to the present invention
3 is an exploded perspective view showing the stunt bike according to the present invention
Figure 4 is a side view showing a stunt bike according to the present invention

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

2 to 4, the stunt bike according to the present invention is a unicycle 10 is coupled to the auxiliary wheel device 50, the vertical frame 11 of the unicycle 10 is the auxiliary wheel device 50 It is fitted to the vertical projection (54) in the center of the lower support frame 53 of the auxiliary wheel device 50 through the square piping 65 of the arch support 60 constituting a), the vertical of the unicycle 10 A support plate 17 disposed at the bottom of the frame 11 is supported by a spring 55 mounted to the lower support frame 53 of the auxiliary wheel device 50.

The unicycle 10 has a vertical frame 11 is composed of a pair of square pipe (11a, 11b), the wheel 13 can be rotated by the pedal 15 between the square pipe (11a, 11b). The upper end of the two square pipes 11a and 11b are connected by the connecting member 12, and the height adjuster 21 of the saddle 20 is fitted to the upper end of the square pipes 11a and 11b. The height adjuster 21 of the saddle 20 is fixed by a bolt 22 fastened to the square pipes 11a and 11b, and the brake lever 31 mounted to the handle 25 of the saddle 20. As a result, the braking device 30 (see FIG. 3) causes the wheel 13 to be braked.

The auxiliary wheel 50 has a lower support frame 53 connecting the front caster 51 and the rear caster 52 with a pair of pipes 53a and 53b. The flange portion 61 of the pair of arcuate supports 60 is joined by fastening means 62 (bolts or rivets), and is formed in the center of the flange portion 61 and the lower support frame 53 of the arcuate supports 60. The spring 55 is mounted on the spring mounting portion 56 of the lower support frame 53 so that the spring 55 is disposed between the vertical protrusions 54.

Stunt bicycle according to the present invention configured as described above can be rotated by tilting the user's body sideways in the process of moving forward, stepping on the pedal (15), such as unicycle, auxiliary wheel device while taking advantage of the unicycle The unicycle 10 does not fall sideways by 50, even beginners can easily ride, the shock transmitted to the unicycle 10 by the spring 55 is completed, the handle 25 of the saddle 20 The wheel 13 may be braked by pulling the brake lever 31 installed in the brake lever 31.
