Transmitter for wireless control

Abstract

To provide a radio control transmitter that generates and transmits a control signal controlling a travelling direction of a toy vehicle, the radio control transmitter comprises: a supporter provided with a bearing section which is spherically recessed at the upper part; a lower case wherein the supporter protrudes through an inner center base; an opening section of an upper case formed at the center wherein the supporter penetrates through; a substrate positioned inside the lower case and perpendicular to the supporter; a plurality of switches which are fixed around a substrate opening section opened on the substrate, and which determine the travelling direction of the toy vehicle; and a control shaft which maintains a plurality of pressing sections positioned on each of the switches, comprising a spherical end axis section which is rotably fixed to the bearing section at the lower part of the control shaft.

       11 . A radio control transmitter that generates and transmits a control signal controlling a travelling direction of a toy vehicle, comprising: 
 a supporter provided with a bearing section which is spherically recessed at the upper part;    a lower case wherein the supporter protrudes through an inner center base;    an opening section of an upper case formed at the center wherein the supporter penetrates through;    a substrate positioned inside the lower case and perpendicular to the supporter;    a plurality of switches which are fixed around a substrate opening section opened on the substrate, and which determine the travelling direction of the toy vehicle; and    a control shaft which maintains a plurality of pressing sections positioned on each of the switches, comprising a spherical end axis section which is rotably fixed to the bearing section at the lower part of the control shaft, the radio control transmitter further comprising: each pressing section which corresponds to the plurality of switches, and which is held by the other end of an elastic section that hangs down to an edge part of a rib which surrounds the center of the control shaft, and wherein the rib installs a lead axis being inscribed to each elastic section and extending downwardly.    
   
   
       12 . The radio control transmitter according to  claim 11  wherein the elastic section is a combination of the rib and an U-shaped spring.  
   
   
       13 . The radio control transmitter according to  claim 11  wherein the opening section on the substrate comprises a circular section on the same axis as the control shaft, and grooves extending out from the control shaft towards the direction of the switches.  
   
   
       14 . The radio control transmitter according to  claim 11  wherein the switches are positioned on the substrate in line symmetry including the control shaft.  
   
   
       15 . The radio control transmitter according to  claim 11  wherein the switches are positioned on the substrate in point symmetry with respect to the control shaft.  
   
   
       16 . The radio control transmitter according to  claim 11 , wherein the control signal is transmitted at a very high frequency or by being multiplexed into an infrared ray.  
   
   
       17 . The radio control transmitter according to  claim 11 , wherein the switch is serially connected to a lightning section flashing if the switch is selected.  
   
   
       18 . The radio control transmitter according to  claim 11 , wherein the toy vehicle installs a battery as a built-in power source and a chargeable connector terminal which is connected to the battery, that comprises another chargeable connector terminal connected to a built-in power source of the toy vehicle and connectable to the chargeable connector terminal installed inside the toy vehicle.
