- the rib installs a lead axis being inscribed to each elastic section and extending downwardly. This prevents the control shaft 50 from becoming uncontrollable by rotating.
- the elastic section is a combination of the rib and an U-shaped spring.
- the radio control transmitter is not only simple in configuration but also controls a plurality of switches by using a single control shaft.
- 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. This prevents the control shaft 50 from becoming uncontrollable by rotating.

The bearingsupporter 90 installs abearing section 92 that is spherically recessed at the uppermost section. The height of the bearingsupporter 90 is almost identical to thesubstrate 30 supported by the plurality ofribs substrate 30 and the contact point of theend axis section 58 and thebearing section 92 are equal in height. - Furthermore, referring to FIG.5 illustrating the cross-section AA of FIG. 1, a connecting section that sets and charges a toy vehicle is prepared next to the
substrate 30.Electrodes electrodes power switch 10 prepared on the substrate. For example, if the chargeable electrodes are installed inside a toy vehicle, by contacting the installed chargeable electrodes toelectrodes electrodes - Moreover, as shown in FIG6, the upper
case opening section 51, a six petal-shaped opening section is prepared. In other words, the open shape has an arc R in 6 directions, and the center of each arc R is positioned to each apex of a hexagon, which is not illustrated. The shape allows thecontrol shaft 50 to shift readily in 6 directions of front, back, front right, rear right, front left and rear left. - The operations of the
radio control transmitter 2 with the above structure in accordance with the present invention will be described. - First of all, in the neutral state, that is, under the state of no manipulation, even if the
control shaft 50 is tilted by its own weight, the neutral state is maintained still, and thepressing sections control shaft 50. - Next, when the
control shaft 50 is titled in the specific direction, the push switches 32, 34, 36 and 38 are pressed by thepressing sections downward rib 9 and locked. Because the locking effect works from thedownward rib 9 to the direction where thecontrol shaft 50 returns to the neutral position, which facilitates thecontrol shaft 50 to return to the neutral position after finishing the manipulation of thecontrol shaft 50. Furthermore, since thecontrol shaft 50 is guided by the six petal-shapedopening section 51, it is movable to 6 directions of front, back, front left, front right, rear left, and rear right. - Herewith, the
lead axis grooves grooves control shaft 50 connected to thelead axis - Furthermore, when the
control shaft 50 is released so as to cease the tilting of thecontrol shaft 50 in the specific direction, thecontrol shaft 50 returns to its upright position by the repelling forces of both springs in the push switches 32, 34, 36 and 38 and the U-shaped springs 66, 68, 70 and 72. Although the U-shaped spring come in contact with the push switch positioned opposite to the tilted direction, however, since the pressing force does not exceed the repelling forces of both springs installed in the push switches 32, 34, 36 and 38 and the U-shaped springs 66, 68, 70 and 72, such that under no circumstance the push switches 32, 34, 36, 38 positioned opposite to the tilted direction become ON. - As described above, a radio control transmitter that generates and transmits a control signal controlling a travelling direction of a toy vehicle comprises a supporter provided with a bearing section which is spherically recessed at the upper part; a 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; and 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 is not only simple in configuration but also controls a plurality of switches by using a single control shaft.
- Moreover, each pressing section corresponds to the plurality of switches, and 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 each pressing body is positioned in a downward direction by preparing a pre-determined space between each pressing body and the top part of the switch. Now that the pressing section has a multiple functions, this contributes to the deletion of a number of structural components of the radio control transmitter. The rib installs a lead axis being inscribed to each elastic section and extending downwardly. This prevents the
control shaft 50 from becoming uncontrollable by rotating. - The elastic section is a combination of the rib and an U-shaped spring. The radio control transmitter is not only simple in configuration but also controls a plurality of switches by using a single control shaft.
- 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. This prevents the
control shaft 50 from becoming uncontrollable by rotating. - The switches are positioned on the substrate in line symmetry including the control shaft or in point symmetry. This prevents introducing errors due to a reaction of the
control shaft 50 occurred by stopping the pressing force into thecontrol shaft 50. - By transmitting the control signal multiplexed into very high frequency wave or an infrared ray, the control signal is capable of transmitting and receiving the transmission media without relying on the specific electromagnetic waves.
- The switch has a lighting section that flashes if the switch is serially connected to the lightning section and selected. Thus, the operationality of the switch in use is improved.
- The toy vehicle installs a battery as a built-in power source and a chargeable connector terminal which is connected to the battery, and comprises a chargeable connector terminal connected to a built-in power source of a radio receiver and connectable to the chargeable connector terminal installed inside the toy vehicle, thereby making it possible to comprise a various functions.
- Furthermore, the present invention is not limited to the previously described embodiment, and various modification and improvements to attain the objective of the present invention should be included within the scope of the present invention. For example, in the present invention, 4 switches are positioned in point symmetry, however, 6, 8, or more multiple switches may be positioned for allowing even better control.
- Moreover, the transmission signal used in the above embodiment is the radio signal, however, signal using other electromagnetic waves such as conventional infrared ray is also applicable.
- According to the present invention, in a radio control of a toy vehicle, by allowing users to manipulate a toy vehicle with their dominant hand, it becomes easier for both right-handed and left-handed users to manipulate a vehicle toy. Furthermore, a radio control transmitter is provided without involving a complex processing, which comprises a fewer number of components.
