Description:
TECHNICAL FIELD 
       [0001]    The present invention relates to a scooter having position recovery and shock-absorbing functions, and more particularly, to a scooter having position recovery and shock-absorbing functions capable of attenuating a shock while enabling safe running even when the scooter is running or runs over an obstacle on a road surface. 
       BACKGROUND ART 
       [0002]    In general, since a scooter having two rear wheels has stability such that the scooter does not easily fall down to a left or right side in comparison with a bicycle or a two-wheeled scooter, anyone can easily run and ride the scooter. In addition, since a relatively wide carrier section can be provided on an upper section of a rear wheel section, the scooter can be used as an inexpensive means of transportation. 
         [0003]    However, since both of the real wheels of such a scooter protrude outward more than a front wheel, the scooter may be more easily turned over than the bicycle or the two-wheeled scooter. 
         [0004]    That is, when a driver changes a direction while running or the scooter runs over an obstacle on a road, the three-wheeled scooter may be tilted in a direction in which a centripetal force is applied, and the scooter may not be able to maintain or rapidly return to an equilibrium state of the rear wheel section. 
         [0005]    Accordingly, scooters have not been popularized as an inexpensive means of transportation that not only ordinary persons, but also the old and the infirm can easily learn to ride due to the above-mentioned problems. 
         [0006]    Accordingly, improvements of forward movement stability and recovery speed of when a center of gravity has moved are urgently required such that drivers can easily drive and stably ride scooters regardless of a running speed of the three-wheeled scooter, a load on the rear wheel section, a road surface state, and so on. 
       SUMMARY OF INVENTION 
     Technical Problem 
       [0007]    In order to solve these problems, an object of the present invention provides a scooter capable of rapidly recovering a position even when a direction of the scooter is changed or the scooter runs over an obstacle on a rod through shock-absorbing means mounted on front and rear sides. 
         [0008]    In addition, another object of the present invention provides a scooter capable of minimizing a shock transmitted along a road surface during running through the shock-absorbing means mounted on the front and rear sides. 
       Solution to Problem 
       [0009]    In order to achieve the aforementioned objects, the present invention provides a scooter having position recovery and shock-absorbing functions, the scooter including: a front wheel on which a steering shaft is mounted in a vertical direction; a front wheel section having a vertical connecting shaft coupled to the steering shaft and a handle mounted on an upper section thereof and configured to perform change of a direction and manipulation; a front coupling shaft having a front coupling section inserted and mounted in a portion at which the steering shaft is coupled to the vertical connecting shaft of the front wheel section, and a front connector having a connecting shaft coupling hole and a shock-absorbing coupling hole formed at one side and a lower end thereof; a footrest section disposed at a rear side of the front wheel section, and having a drive unit mounted on one side thereof, a vertical connecting section and a horizontal connecting section bent at a front side thereof, and a footrest connecting section having a coupling hole bent at a center thereof to be fixed to the connecting shaft coupling hole through a fastener; a shock-absorbing bar inserted and mounted in the shock-absorbing coupling hole of the front coupling shaft and having shock-absorbing connectors formed at both sides thereof at positions corresponding to shock-absorbing connectors formed at both sides of the horizontal connecting section; a front shock-absorbing means configured to recover a position and attenuate a shock using shock-absorbing members having ends fixedly coupled to the shock-absorbing connectors; and rear wheels mounted on both sides of a rear sides of the footrest section. 
       Advantageous Effects of Invention 
       [0010]    According to the present invention, as the shock-absorbing means are mounted on the front and rear sides, the position of the scooter can be rapidly recovered even when the direction of the scooter is changed or the scooter runs over an obstacle on a road while running, and anyone can easily use the scooter regardless of age or sex. 
         [0011]    In addition, as the shock-absorbing means are mounted on the front and rear sides, a shock transmitted along the road surface during running can be minimized, and a fatigue transmitted to a user can be minimized even in long term use.

         [0027]    In addition, shock-absorbing connectors  56  are symmetrically formed at both sides of the horizontal connecting section  53  to couple the front shock-absorbing means  70  thereto. 
         [0028]    The shock-absorbing bar  60  inserted into the shock-absorbing coupling hole  44  that constitutes the front coupling shaft  40  has a predetermined length to be inserted into the shock-absorbing coupling hole  44  of the front coupling shaft  40 , and shock-absorbing connectors  61  are symmetrically formed at both sides thereof. 
         [0029]    Here, the shock-absorbing connectors  61  are formed at positions corresponding to the shock-absorbing connectors  56  symmetrically formed at both sides of the horizontal connecting section  53 . 
         [0030]    The front shock-absorbing means  70  having ends fixed to the shock-absorbing connectors  56  and  61  are configured to attenuate a shock while recovering a position during running on the road surface or the ground. 
         [0031]    Here, the front shock-absorbing means  70  are coupled to the shock-absorbing connectors  56  and  61  using shock-absorbing members. The shock-absorbing members may be constituted by any one selected from a shock absorber, a spring, a rubber bar, and a connecting wire constituted by a plurality of rubber strings. In the present invention, an example constituted by the shock absorber will be exemplarily described.

In the present invention, an example constituted by the shock absorber will be exemplarily described. 
         [0036]    The embodiment of the scooter having position recovery and shock-absorbing functions configured as described above will be described with reference to the accompanying drawings. 
         [0037]    First, the steering shaft  21  is mounted on the center of the front wheel  20 , the vertical connecting shaft  31  is coupled to the steering shaft  21 , and then the front wheel section  30  on which the handle  32  is mounted to perform change of a direction and manipulation is mounted on an upper section thereof. 
         [0038]    Here, the front connector  42  having the connecting shaft coupling holes  43  formed at one side and a lower end thereof and the front coupling section  41  of the front coupling shaft  40  having the shock-absorbing coupling hole  44  are inserted into the portion at which the steering shaft  21  is coupled to the vertical connecting shaft  31  of the front wheel section  30 . 
         [0039]    In addition, the drive unit  51  is mounted on one side of the rear side of the front wheel section  30 , the vertical connecting section  52  and the horizontal connecting section  53  are bent at the front side, and the footrest connecting section  54  having the coupling hole  55  and the footrest section  50  having the shock-absorbing connectors  56  are mounted on the center and both sides of the horizontal connecting section  53 . 
         [0040]    That is, after disposing the footrest connecting section  54  having the coupling hole  55  at the front connector  42 , the fastening bushes  102  are mounted on both sides of the coupling hole  55 , the bolt  101  passes through the connecting shaft coupling hole  43  and the coupling hole  55 , and then the bolt  101  is fixedly fastened using the fixing nut  103 . 
         [0041]    Next, the shock-absorbing connectors  56  formed at both sides of the horizontal connecting section  53  and the shock-absorbing bars  60  having the shock-absorbing connectors  61  formed at corresponding positions are inserted and mounted in the shock-absorbing coupling hole  44  of the front coupling shaft  40 . 
         [0042]    Then, when the rear wheels  80  mounted on both sides of the rear side of the footrest section  50  are mounted on the shock-absorbing connectors  56  and  61  after fixing the shock absorbers of the front shock-absorbing means  70  to the ends thereof, assembly of the scooter  10  having position recovery and shock-absorbing functions is terminated. 
         [0043]    Here, the rear shock-absorbing means  90  includes the pair of fixing plates  91  mounted on the frame  57  that constitutes the footrest section  50  at an interval and having the shock-absorbing connecting hole  91   a  and the shaft coupling hole  91   b  formed at both ends and the frame connecting hole  91   c  formed at one side to be fixedly mounted on the frame  57  through the fastener  100 , the support  92  mounted between the fixing plate  91  and the fixing plate  91 , and the shock-absorbing member  93  coupled to the fixing jig  58  formed at the frame  57  and the shock-absorbing connecting hole  91   a  of the fixing plate  91 . 
         [0044]    Here, an assembly sequence of the scooter having position recovery and shock-absorbing functions may be configured differently from the above-mentioned description. 
         [0045]    In this state, the case in which the scooter  10  having position recovery and shock-absorbing functions is used is as follows. 
         [0046]    First, the scooter  10  having position recovery and shock-absorbing functions performs various functions in addition to change of direction while running using the handle  32  mounted on the front wheel section  30  and other additional devices. 
         [0047]    Here, in the scooter  10  having position recovery and shock-absorbing functions, the shock absorbers of the shock-absorbing means  70  and  90  mounted on the front and rear sides can absorb the shock transmitted from the road surface to minimize transmission of the shock. 
         [0048]    In addition, when the scooter  10  having position recovery and shock-absorbing functions changes a direction or runs over an obstacle while tilted, the scooter  10  can rapidly recover the position and attenuate the shock through the shock-absorbing means  70  and  90 . 
         [0049]    That is, the shock-absorbing members of the shock-absorbing means  70  and  90  can attenuate the shock and recover the position by closely attaching the tilted portion to the ground in a maximally rapid manner while the shock absorber moves forward as the applied force is weakened. 
         [0000]    Embodiments of the invention have been discussed above with reference to the accompanying drawings. However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes as the invention extends beyond these limited embodiments. For example, it should be appreciated that those skilled in the art will, in light of the teachings of the present invention, recognize a multiplicity of alternate and suitable approaches, depending upon the needs of the particular application, to implement the functionality of any given detail described herein, beyond the particular implementation choices in the embodiments described and shown above. That is, there are numerous modifications and variations of the invention that are too numerous to be listed but that all fit within the scope of the invention.
