Description

Folding Jumping-bike for horse-riding effect "

The present invention relates to a folding jumping bicycle having an equestrian effect. More specifically, elastic springs are provided between the saddle frame and the lower frame and the handle frame, respectively, so that the user applies a load by using his or her body weight, thereby allowing the bicycle to jump up and down due to elasticity. The present invention relates to a folding jumping bicycle having a horse-riding effect that can be kept minimized.

In general, bicycles are a useful tool for locomotion as well as a role for fitness in modern life. Recently, as interest in health and leisure has increased, demand for exercise and hobby activity has been increasing, and bicycles having various purposes and functions have been developed and used, such as mountaineering, stunning, and the like.

For example, Korean Patent Application No. 20-318647 discloses a rear frame having a front frame to which front wheels are connected and a saddle to be installed, a rear frame to which a rear wheel is attached and which is coupled to the front frame via a connection hinge portion, And the other side is connected to one side of the rear frame to provide a shock-absorbing shock absorber. The bicycle has been developed and used so as to mitigate the shock transmitted to the frame when the vehicle is traveling on an unpaved road or uneven road.

However, the present invention solves only the problem of shock mitigation that is transmitted to the frame portion due to uneven road or floor condition, and can not expect any effect for a user who intends to exercise and leisure activities.

In addition, the conventional bicycle requires complicated operations such as turning a screw to fix the folding part in the folding or unfolding process, or the folding part is not firmly engaged so that an accident occurs when the folding part is released by an external impact There was a problem.

For example, the portable bicycle disclosed in Korean Patent Registration No. 0854018 is a folding type in which a saddle and a rear wheel portion are moved toward a front wheel and a handlebar portion, and includes a handlebar folding device and a vehicle body length adjusting device. Here, the handle bar was folded by the handle bar folding device, and the length of the bicycle was adjusted by the body length adjusting device.

However, a plurality of gears, idle gear pins, and the like are used for the handle bar folding device, and such a complicated structure has a problem in that the manufacturing complexity and the unit cost increase. In addition, the front and rear length of the bicycle was shortened.

Accordingly, there is a need for a solution that can solve all of the above problems.

Next, in FIG. 8C, the second sliding member 650 mounted on the handle bar 600 is pressed toward the handle bar elastic body 640, and then the third handle bar 630 is rotated. At this time, the folding engagement groove 635 of the third handle bar 630 is engaged with the engagement member 623 mounted on the second handle bar 620, so that the rotation angle of the folding shaft of the third handlebar 630 is limited do.

8D, the second handle frame 420 is inserted into the first handle frame 410 through the first hinge part 440 provided on the second handle frame 420, and the second handle frame 420, The second handle frame 420 is folded toward the rear wheel 120 while the engagement between the first handle frame 420 and the second handle frame 420 is released. This completes the simple folding that is portable.

8E, the front wheel 110 and the handle frame 400 are coupled to each other through a second hinge portion 260 provided between the first and second lower frames 210 and 220, The folding process of the bicycle according to the present invention is finally completed.

<The process of opening the bicycle>

8E, the front wheel and the handle frame on the opposite side of the rear wheel are rotated clockwise to rotate the first and second lower frames 210 and 220, In a parallel state.

The first handle frame 410 and the second handle frame 410 are rotated by rotating the second handle frame 420 exposed on the upper portion of the first handle frame 410, 420 are coupled to each other in a straight line.

The third handle frame 430 is also pulled out from the second handle frame 420 by the handle clamp 450 and fixed.

Next, as shown in FIG. 8D, when the third handlebar 630 is rotated, it is fixed in parallel with the second handlebar 620. At this time, the unfolding angle of the third handlebar 630 is restricted by the engagement of the release engagement grooves 634 formed on the third handlebar 630 with the engagement members 623 of the second handlebar 620. The second handle bar groove 633 formed in the third handle bar 630 is aligned with the first handle bar groove 653 formed in the second handle bar 620 and the first and second folding preventing surfaces 653a and 633a Are prevented from being arbitrarily collapsed by the third handle bar 630 being in close contact with each other. At this time, the second sliding member 650 is naturally returned to the engagement position by the restoring force of the handle bar elastic body 640. When the third handlebar 630 is folded and brought into contact with each other, the third handlebar 630 and the second slidebar 650 have a curved longitudinal profile, and the third handlebar 630 is unfolded, So that the first and second handlebar grooves 653 and 633 match each other naturally.

Next, the first saddle frame 310 is pivoted, and the second saddle 140 is pivoted by the shaft and is fastened to the first saddle frame 310 by the desorption member 380.

Next, the third saddle frame 330 is pulled out and fixed from the second saddle frame 320 by the saddle clamp 350, whereby the folded bicycle 100 is unfolded.

Thus, by providing the folding jumping bike 100 having the equestrian effect according to the embodiment of the present invention, the user can obtain thrill, pleasure, etc. through exercise through jumping. It is possible to increase the momentum and to minimize the volume, so that it is convenient to store and move, and the folding and unfolding method is simple and easy to use.

The folding jumping bicycle having the horseback riding effect described above can be applied not only to the configuration and the method of the above-described embodiments, but the embodiments can be applied to all or some of the embodiments selectively And may be configured in combination.
