Abstract:
A shock absorber for a scooter has a front shock absorber which is applied to a front wheel of the scooter and a rear shock absorber which is applied to a rear wheel of the scooter. When the scooter is ridden over a bumpy surface, both the shock absorbers minimize shocks to the scooter emanating from the bumpy surface.

Description:
BACKGROUND OF THE INVENTION  
         [0001]    1. Field of the Invention  
           [0002]    The present invention is related to a shock absorber, and more particularly to a shock absorber for a scooter which effectively minimizes shocks when the scooter is ridden over bumpy surfaces.  
           [0003]    2. Description of Related Art  
           [0004]    Recently a scooter has become a popular vehicle for riding short distances due to its light weight and small volume, as well as its fun-to-ride aspect. Generally, a scooter comprises of a body, a handlebar, a front wheel, and a rear wheel. However, the wheels of the scooter are made of hard rubber and so the scooter can not absorb shocks when it is ridden over bumps because the material of the wheels lacks resilience.  
           [0005]    When the scooter is ridden over bumpy surfaces, etc, the rider will experience shock and discomfort, as well as danger through the chance that control is lost due to the lack of effective shock absorbency.  
           [0006]    To overcome the shortcomings, the present invention tends to provide a shock absorber for a scooter to mitigate and obviate the aforementioned problems.  
         SUMMARY OF THE INVENTION  
         [0007]    The main objective of the invention tends to provide a shock absorber for a scooter which effectively minimizes shocks when the scooter is ridden over bumpy surfaces.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0012]    With reference to FIG. 1 and FIG. 2, a partial portion of a scooter fitted with shock absorbers in accordance with the present invention is shown. The scooter has a body ( 10 ), a handlebar base ( 20 ) securely mounted on a front end of the body ( 10 ), a head tube ( 21 ) that a handlebar stem ( 211 ) pivotally extends wherein connected to the handlebar base ( 20 ), a wheel base ( 22 ) connected to an end of the head tube ( 21 ), a front shock absorber ( 30 ), and a rear shock absorber ( 40 ).  
         [0013]    The front shock absorber ( 30 ) comprises two front V-shaped pieces ( 31  and  31 ′), a front piston ( 32 ) extending from a front housing ( 322 ), a first pin ( 33 ), a second pin ( 34 ) and a first spring ( 35 ).  
         [0014]    First ends of both front V-shaped pieces ( 31  and  31 ′) are pivotally connected to the wheel base ( 22 ) by a first pin ( 33 ) and second ends of both front V-shaped pieces ( 31  and  31  ′) are also pivotally connected by the second pin ( 34 ). A front wheel ( 23 ) is rotatably connected between the front V-shaped pieces ( 31  and  31  ′). The front piston ( 32 ) has a first end slidingly received in the front housing ( 322 ), and a second end pivotally secured to a joint of the head tube ( 21 ) and the wheel base ( 22 ). The front housing ( 322 ) has a first end defining an opening into which the front piston ( 32 ) is securely yet slidingly received and a second end pivotally secured to the second pin ( 34 ), wherein a first spring ( 35 ) is mounted around the front piston ( 32 ) and the front housing ( 322 ).  
         [0015]    The rear shock absorber ( 40 ) comprises two rear V-shaped pieces ( 41  and  41 ′), a rear piston ( 42 ) extending from a rear housing ( 422 ), a third pin ( 43 ), a fourth pin ( 44 ), a fifth pin ( 45 ), a second spring ( 46 ), two bases ( 47  and  47 ′) and two triangle pieces ( 48  and  48 ′).  
         [0016]    The two bases ( 47  and  47 ′) are securely connected to a rear portion of the body ( 10 ) and extend from opposed sides of the body ( 10 ). The two triangle pieces ( 48  and  48 ′) are respectively formed on the bases ( 47  and  47 ′).  
         [0017]    First ends of both rear V-shaped pieces ( 41  and  41  ′) are pivotally connected to the respective bases ( 47  and  47 ′) with the third pin ( 43 ) and second ends of both rear V-shaped pieces ( 41  and  41 ′) are pivotally connected with the fourth pin ( 44 ) extending therebetween. The fifth pin ( 45 ) is pivotally connected between the two triangle pieces ( 48  and  48 ′). A rear wheel ( 24 ) is rotatably connected between the two rear V-shaped pieces ( 41  and  41  ′). The rear piston ( 42 ) has a first end slidingly received in the rear housing ( 422 ), and a second end pivotally secured to the fifth pin ( 45 ). The rear housing ( 422 ) has a first end defining an opening into which the rear piston ( 42 ) is securely yet slidingly received and a second end pivotally secured to the fourth pin ( 44 ), wherein the second spring ( 46 ) is mounted around the rear piston ( 42 ) and the rear housing ( 422 ).  
         [0018]    With reference to FIG. 3, wherein only the front portion of the scooter and the front shock absorber ( 30 ) are shown, when the scooter is ridden over a bumpy surface, the front V-shaped pieces ( 31  and  31 ′) are pivoted upward about the first pin ( 33 ) due to the front wheel ( 23 ) encountering bumps, whereby the first spring ( 35 ) is temporarily compressed and the shock to the scooter is minimized. The rear shock absorber ( 40 ) function in a manner the same as the front shock absorber ( 30 ).  
         [0019]    It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
