DETAILED DESCRIPTION OF THE PRESENT INVENTION

[0031] The innovation is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the innovation can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate a description thereof. Various embodiments are discussed hereinafter. It should be noted that the figures are described only to facilitate the description of the embodiments. They are not intended as an exhaustive description of the invention and do not limit the scope of the invention. Additionally, an illustrated embodiment need not have all the aspects or advantages shown. Thus, in other embodiments, any of the features described herein from different embodiments may be combined.

[0032] As noted above, there is a long felt need in the art for an improved throttle cable system for rescue vehicles like ATVs and jet skis. There is also a long felt need in the art for a dual throttle cable system that provides two independent throttles and cables for selectively actuating one of the throttle cable systems. Additionally, there is a long felt need in the art for two independent throttles and cables in rescue vehicles that enables activation of second throttle cable when a first throttle cable breaks down. Moreover, there is a long felt need in the art for improved throttle cable system that prevents rescue operations from taking additional time due to malfunctioning of a single throttle system of rescue vehicles. Further, there is a long felt need in the art for throttle cable system that accommodates left-handed drivers. Furthermore, there is a long felt need in the art for an improved throttling system that can be easily implemented in ATVs, jet skis, snowmobiles, and other recreational vehicles. Finally, there is a long felt need in the art for dual throttle cable system that facilitates acceleration of a rescue vehicle using the single throttle and enabling activation of the opposite throttle cable upon break down of the actuated throttle cable.

[0033] The present invention, in one exemplary embodiment, is an improved throttling system for ATVs, jet skis, snowmobiles, and recreational vehicles. The system includes a dual cabled throttle assembly featuring two individual throttle cables attached to corresponding throttle control bars, a carburetor independently connected to said throttle cables, wherein said throttle cables meet at a central plate and yoke, enabling a user to select and actuate a single throttle for actuating and powering the vehicle.

[0034] Referring initially to the drawings, FIG. 1 illustrates a top view of an ATV equipped with dual throttle control system of the present invention in accordance with the disclosed architecture. The dual throttle control system 100 of the present invention includes independent left throttle cable 102 and right throttle cable 104. The left throttle cable 102 is coupled to a left thumb throttle control 106 and the right throttle cable 104 is coupled to a right thumb throttle control 108 and the thumb throttle controls 106, 108 function as throttle levers for selectively and independently operating the respective throttle cables 102, 104.

[0035] The thumb throttle controls 106, 108 are preferably positioned on the handlebar 110 enabling a rider of the vehicle to easily control and actuate the throttle cables 102, 104. The thumb throttle control 106, 108 better enables the ATV 114 rider to shift bodyweight for optimal vehicle maneuverability while still maintaining precise throttle control.

[0036] The left throttle cable 102 connects the thumb throttle control 106 to a carburetor throttle 112 (shown in FIG. 2) of internal combustion engine of the ATV 114. Similarly, the right throttle cable 104 connects the thumb throttle control 108 to the carburetor throttle 112 of internal combustion engine of the ATV. The detailed description of the carburetor throttle 112 is described in FIG. 2.

[0037] During use of the ATV, one of the left and right throttle systems is used for providing acceleration to the ATV as per preferences of a rider. For example, when the right throttle cable 104 is actuated using the right thumb control 108, then, the left throttle cable 102 is not used and in case of a malfunction, break down, and/or crash damage in the active right throttle cable 104, the left throttle cable 102 is actuated for providing acceleration and therefore, eliminates the ATV from breaking down and prevents rescue situations from taking additional time due to malfunctioning rescue and safety vehicles. It is to be appreciated that when the right throttle control 108 is operational, the left throttle control 106 can be prohibited (i.e. disengaged) from operation, and vice versa. Thus, the throttle control can be selected and limited to one of the controls 106, 108 as desired by the user.

[0038] FIG. 2 illustrates a perspective view of connection of the throttle cables with the throttle carburetor of the present invention designed to deploy in rescue vehicles in accordance with the disclosed architecture. The carburetor 112 of the combustion engine of a vehicle in which the dual throttle system is installed is a modified carburetor to accommodate two independent throttle cables 102, 104. The carburetor 112 helps in mixing fuel and air together for facilitating internal combustion inside an internal combustion engine and can be independently actuated by any of the two throttle cables 102, 104.

[0039] The left throttle cable 102 is inserted into a first throttle cable shaft 202 and the right throttle cable 104 is inserted into a second throttle cable shaft 204. The cables 102, 104 connect the thumb throttle controls 106, 108 respectively to the shafts 202, 204. It should be noted that a corresponding choke cable slot for each throttle cable slot may also be present in the carburetor 112 for restricting the flow of air in the carburetor of the engine. The shafts 202, 204 are integrally connected to a mixing chamber 206 used for mixing air and fuel together.

[0040] The carburetor 112 further has essential components like a fuel line connection 208, oil injector connection 210, throttle stop screw 212 and more for functioning of the carburetor 112.

[0041] It should be noted that the dual throttle system design is for vehicles whose steering unit does not rotate 360 degrees. Another embodiment of the system is designed for vehicles with steering unit capable of rotating 360 degrees.

[0042] FIG. 3 illustrates a perspective view showing activation of a second throttle cable upon break down of a first throttle cable of the dual throttle cable system of the present invention in accordance with the disclosed architecture. When one of the throttle cables, throttle cable 102, for example snaps or becomes damaged, the throttle system 100 enables the use of second throttle cable 104 for providing acceleration to the vehicle, thereby eliminating breakdown time and possible stranding. More specifically, when the left throttle cable 102 breaks, snaps, wears down, or comes out of adjustment, the drivability of the vehicle is not affected unlike with conventional single throttle cable systems, as a rider of the vehicle can actuate the right throttle cable 104 using the thumb controller 108.

[0043] The thumb controller 108 when actuated, enables the throttle cable 104 to actuate and facilitate acceleration. The rider is able to actuate the throttle without removing thumb or the palm of hand from contact with the handlebar. Similarly, when the right throttle cable 104 breaks down, the left throttle cable 102 can become functional using the corresponding thumb control positioned on the handlebar.

[0044] FIG. 4A illustrates a jet ski equipped with dual throttle system of the present invention in accordance with the disclosed architecture. As illustrated, the independent throttle control bars 402, 404 are positioned on the handlebar 406 of the jet ski 400 enabling independent control and activation of the throttle cables 406, 408. The first throttle cable 406 is coupled to the throttle control bar 402 and the second throttle cable 408 is coupled to the control bar 404 for independent operation and facilitation of acceleration of the jet ski 400.

[0045] The throttle system (including carburetor 412) is positioned inside the central housing 410 of the handlebar 406 and is coupled to the throttle cables 406, 408. As illustrated, in FIG. 4A, the left throttle control bar 402 is used by a rider for accelerating the jet ski 400 using the left throttle cable 406. The right throttle cable 408 can be used in a similar manner using the throttle control bar 404. In the present embodiment, the throttle cables 406, 408 are housed inside housing of the jet ski 400, unlike the open throttle cables shown in ATV of FIG. 1.

[0046] FIG. 4B illustrates another embodiment of the dual throttle system of the present invention used in a jet ski for providing acceleration in accordance with the disclosed architecture. The carburetor in the present embodiment is a half-moon dual carburetor 412 that has separate throttle cable connectors 414, 416. The first connector 414 is coupled to the first throttle cable 406 using a first connector slot 4140 and the second connector 416 is coupled to the second throttle cable 408 using a second connector slot 4160 enabling separate connections with the fuel and air mixing chamber 418.

[0047] It should be appreciated that the dual throttle control system can be designed to accommodate various carburetor designs and various throttle cables. Throttle cables of both push and pull types can be accommodated in the dual throttle system of the present invention and therefore, the system can be used for accelerating any type of rescue vehicle without any delay.

[0048] FIG. 5 illustrates a perspective view of a yoke and plate system used in the dual control throttle system for vehicles that have steering unit capable of rotating 360 degrees in accordance with the disclosed architecture. The present embodiment of the system 500 has a central plate 502 and a yoke for individual throttle cable for enabling connection to a carburetor of an engine. The first throttle cable 506 is attached to the yoke 504 and the central plate 502 enabling independent movement and use of the cable 506 for actuating a vehicle. Similarly, the second throttle cable 508 is attached to yoke 504 and the central plate 502 enabling independent movement and use of the cable 508 for actuating the vehicle.

[0049] The system 500 is designed to use with vehicles that have steering unit capable of rotating 360 degrees and thus the yoke and the plate are helpful in working of the throttle system.
