Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to a steering wheel, and more particularly to a steering wheel having a direction light button. 
         [0003]    2. Description of the Prior Art 
         [0004]    As shown in  FIG. 1 , a conventional automobile steering wheel comprises a lever  10  located at the left side of a steering wheel  11 . When the driver wants to take a turn, the lever  10  is pushed upward to indicate a right turn or the lever  10  is pushed downward to indicate a left turn. The end of the lever  10  is provided with a rotatable switch  101  which is used to turn on/off the headlight of the automobile. When in use, the driver has to move his/her left hand to control the operation of the lever  10 . Besides, the up and down movements of the lever  10  don&#39;t direct correspond to the left and right turnings, which can&#39;t be operated by intuition. In addition, the rotatable switch  101  of the lever  10  may be operated wrongly to turn on the headlight when the driver wants to take a turn. 
       SUMMARY OF THE INVENTION 
       [0005]    The present invention is to provide a steering wheel having a direction light button, which comprises a steering wheel and a direction light control button disposed at a predetermined position of the steering wheel. The direction light control button includes at least one left turn button and at least one right turn button. When the driver wants to take a turn, the driver can operate the direction light control button disposed on the steeling wheel with his/her hands. This is very handy for the driver to take a turn. The left turn button and the right turn button of the direction light control button can be operated by intuition, avoiding any wrong operation.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0014]    Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings. 
         [0015]    As shown in  FIG. 2 , a first embodiment of the present invention comprises a steering wheel  20 , a direction light control button  30 , a headlight control button  40 , and a recovery device  50 . 
         [0016]    The steering wheel  20  includes a circular grasp portion  21 , a central portion  22  and a connection portion  23  which is connected between the central portion  22  and the grasp portion  21 . 
         [0017]    The direction light control button  30  includes a left turn button  31  and a right turn button  32 . In this embodiment, the left turn button  31  and the right turn button  32  are mechanical buttons, which can by touch buttons, knobs or the like. The left turn button  31  and the right turn button  32  are respectively located at two sides of the grasp portion  21  of the steering wheel  20  close to the connection portion  23 . 
         [0018]    The headlight control button  40  is located at one side of the central portion  22  of the steering wheel  20  or at any desired position of the steering wheel  20 . The headlight control button  40  is composed of three press buttons  41  to elect a switch mode. 
         [0019]    The recovery device  50 , referring to  FIGS. 3 and 4 , includes a left unit  51 , a right unit  52  and a central unit  53  which are located under the central portion  22  of the steering wheel  20 , a control unit  54  which is located on a bottom of the central portion  22 , and a controller  55 . 
         [0020]    In order to understand the features of the present invention, the technical means of application, and anticipated effects, the use of the present invention is described hereinafter. 
         [0021]    Referring to  FIG. 2 , when taking a right turn, the driver presses the right turn button  32  with his/her right hand to actuate a direction light  60 . At this time, the driver&#39;s hands are still on the steering wheel  20  for ensuring driving safety. Besides, when taking a right turn, to press the right turn button  32  by intuition can avoid any wrong operation. 
         [0022]    Furthermore, referring to  FIGS. 3 to 5 , when the right turn button  32  is pressed, the control unit  54  on the bottom of the steering wheel  20  will touch off the right unit  52 , the left unit  51 , and then the right unit  52  in sequence. After the turning is achieved, the steering wheel  20  will bring a recovery motion for a straight route. This moment, the control unit  54  will touch off the right unit  52  again to know that the car has made a direction change. When the control unit  54  and the central unit  53  are overlapped, the central unit  53  will actuate the controller  55  to stop the operation of the direction light  60 . The central unit  53  can be omitted. Only the control unit  54  and the left unit  51 /the right unit  52  are required to touch off repeatedly for knowing the change of direction, such that the controller  55  stops the operation of the direction light  60 . 
         [0023]    In addition, the press buttons  41  of the headlight control button  40  are located at the side of the central portion  22  of the steering wheel  20 , which are separated from the direction light control button  30  for avoiding any wrong operation. The driver&#39;s hands are able to control the headlight control button  40 , without leaving the steering wheel  20 . 
         [0024]      FIG. 6  is a perspective view according to a second embodiment of the present invention, which is substantially similar to the first embodiment with the exceptions described hereinafter. The left turn button  31  and the right turn button  32  of the direction light control button  30  are located at the same side of the steering wheel  20 . A stop button  33  is provided between the left turn button  31  and the right turn button  32 . The driver can operate the direction light control button  30  with one single hand. When the driver wants to stop the direction light  60 , he/she can direct press the stop button  33  or the original preset button. Besides, the headlight control button  40  is located on the connection portion  23 , which uses a changeover switch  42  to control the operation. 
         [0025]      FIG. 7  is a perspective view according to a third embodiment of the present invention, which is substantially similar to the first embodiment with the exceptions described hereinafter. Two pairs of direction light control buttons  30  are provided under two sides of the connection portion  23  of the steering wheel  20 . Each pair of the direction light control buttons  30  includes a left turn button  31  and a right turn button  32 . The headlight control button  40  is located at one side of the central portion  22 , which uses a lever switch  43  to control the operation. 
         [0026]      FIG. 8  is a perspective view according to a fourth embodiment of the present invention, which is substantially similar to the first embodiment with the exceptions described hereinafter. Two pairs of direction light control buttons  30  are provided on the back of two sides of the connection portion  23  of the steering wheel  20 . Each pair of the direction light control buttons  30  includes a left turn button  31  and a right turn button  32 . The headlight control button  40  is located at one side of the central portion  22 , which uses a press switch  44  to control the operation. 
         [0027]    Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
