Title: Direction signal light

Description:
TECHNICAL FIELD OF THE INVENTION 
     The present invention relates to direction signal light, and in particular, to direction signal light which is extendable with respect to its width. 
     DESCRIPTION OF THE PRIOR ART 
     Bicycle with wireless transmission in controlling the direction signal light mounted at the end of the bicycle is not widely known but wireless transmission is very convenient in controlling signal. It is therefore conventional type of direction light structure for bicycle should be improved. 
     Bicycle for professional cyclists generally has a seat pad a higher position, the rear light mounted at a horizontal support below the seat pad allows people from behind to easily see the cyclists. However, for bicycles with a low seat pad, it is important to have a direction signal light structure which can be extended. 
     SUMMARY OF THE INVENTION 
     Accordingly, it is an object of the present invention to provide a direction signal light for bicycle comprising a controller, a direction signal seat, a red light and amber light module, characterized in that the controller having a touch control switch for left turning and right turning light is disposed at one end position of the handle of the bicycle, signal from the touch control switch is transmitted via wire or wireless transmission device to the direction signal light seat at the bottom section of the seat pad of the bicycle; the front section of the direction signal light seat is secured to a supporting rod below the seat pad, and the rear section of the direction signal light seat is provided with a center red light, a left amber light and a right amber light, and the interior of the direction signal light seat contains a wireless signal receiving device; and the red light is mounted at the center position at the rear section of the direction signals light seat, upon the triggering of the red light, the red light remains, and the left amber and right amber light being at the side position is extendable or retractable and the light or right amber light blinks when the switch is on. 
     Other objects, and advantages will become more apparent in view of the following detailed description in conjunction with the accompanying drawings.

         FIG. 1  shows a flowchart of a wireless transmission system of a controller of the present invention. 
         FIG. 2  shows a flowchart of a wireless receiving system of a direction signal light seat of the present invention. 
         FIGS. 3 to 5  show schematic views of the preferred embodiment of the present invention. 
     
    
    
     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring to  FIG. 1 , there is shown a schematic flowchart of a wireless transmission system of a controller in accordance with the present invention. When a wireless transmission system  10  is switched on, batteries and battery wire  11  respectively supply electrical energy to coding IC  13  and transmission wire  14 , and the wires for switching circuit  12  for the red light, left and right turning amber light is first connected to the coding IC  13  and is then connected to the transmission wire  14 . Via an antenna  15 , the control signal for left and right turning amber light is transmitted to the direction signal light seat as flashing amber light for left and right turning. The center red light is permanently lighted without turning off. 
     Referring to  FIG. 2 , there is shown a flowchart of a wireless receiving system of a direction light seat in accordance with the present invention. The wireless receiving system  20  is in combination with the wireless transmission system of the controller  10  and are in operation. Batteries and power source wire  22  respectively provide electrical energy to the receiving wire  23 , the decoding IC  24 , LED and the controlling wire  25 , and the signal from ON and OFF signal transmitted from the controller via the antenna  21  is received, by first passing the receiving wire  23 , via the decoding IC  24 , then to the LED and control wire  25  as lighted. 
     Referring to  FIG. 3 , there is shown a schematic view of a preferred embodiment in accordance with the present invention. The controller  30  is mounted onto the handle bar  31  of a bicycle. The rear light seat  32  is positioned at a supporting rod  34  beneath the seat pad  33 . The cyclist switches on the controller  30  and the power source of the direction signal light seat  32 . At this point of time the center red light  35  is lighted and remains lighted. If the cyclist wishes to turn the bicycle to left side, the left turn on the panel of the controller  30  is touched and the left turn amber light  36  flashes and at the same time, it is indicated on the panel. After the bicycle is in a straight position, the left turn signal is off. If the cyclist wishes to turn right, the left turn switch on panel of the controller  30  is touched, and the right turn light flashes and also is indicated on the panel. The wide of the signal light can be extended outward (laterally) if it is needed. 
     The left turn light  36  and the right turn light  37  is extendable from the housing  38 . 
     As shown in  FIG. 4 , the top drawing indicates the light seat  32  is yet to be extended laterally. One middle drawing indicates the left turn amber light  36  is extended and the right turn light  37  is extended halfway. The bottom drawing indicates that the extended recess  39  and protrusion  40  of the direction signal light seat  32  is in combination with the protruded edge at the inner edge of the housing  38  and the protruded point  41 , and is embedded at the blocking plate  43  of the slip  42 . Thus the length of the extension can be extended based on requirement 
     While the invention has been described with respect to preferred embodiment, it will be clear to those skilled in the art that modifications and improvements may be made to the invention without departing from the spirit and scope of the invention. Therefore, the invention is not to be limited by the specific illustrative embodiment, but only by the scope of the appended claims.
