Motorcycle throttle lock cruise control

Abstract

A cruise control for a vehicle having a mounted rotatable accelerator sleeve and throttle housing which is mounted to a handlebar. The cruise control mounts entirely to the accelerator sleeve and rotates in perfect unity with the throttle when it is rotated. The cruise control is mounted between the throttle housing and the rubber/plastic grip's inner end, directly onto the accelerator sleeve. When the single button of the cruise control is pressed, the cruise control engages and uses friction against the surface of the throttle housing to hold the throttle in place. The operator can force the throttle to rotate by overpowering the friction caused by the cruise control, or preferably, they can disengage the cruise control by pressing the single button again, resetting the cruise control to be engaged again by pressing the single button.

DETAILED DESCRIPTION OF THE INVENTION

(14) This invention 12, illustrated in the accompanying drawings, is meant to be used as a cruise control 12 for a vehicle which is steered by handlebars 1 and accelerates, maintains and decelerates its speed with a mounted rotatable accelerator sleeve unit 9, similar to a motorcycle. An example of this type of mounted rotatable accelerator sleeve unit 9 is shown in FIGS. 1-3 and 12-13. In FIG. 1 the rubber/plastic grip 4 is fixed to the accelerator sleeve 5 which is mounted to the throttle housing 2. The throttle housing 2 is mounted to the handlebars 1, and has, in this example, two throttle cables 3 protruding out of the throttle housing 2.

(15) FIG. 2 shows the exposed segment of the accelerator sleeve 5 between the throttle housing 2 and the rubber/plastic grip 4, which is where the invention 12 will be mounted. In FIG. 3, the cruise control 12 is attached to the mounted rotatable accelerator sleeve unit 9, and when combined 20, shows where the invention 12 attaches to the accelerator sleeve 5. FIG. 4 shows the pivotable clamping arm 10, its outer hinge 14 and the sidewall of the bolt hole 15. FIG. 4 shows the invention 12 in a position where the nut and bolt 16 have only been cinched down slightly, allowing the invention 12 to be mounted to accelerator sleeve 5 with a large diameter. FIG. 4 is a perspective view, viewing the side of the invention 12 that faces the throttle housing 2. In this view, you can see how the stopper 18 is positioned in relation to the pivotable clamp arm 10 and the single button 8. FIG. 5 shows the invention 12 with the nut and bolt 16 cinched tight to fit on an accelerator sleeve 5 with a narrow diameter. FIG. 6 shows the pivotable clamp 10 fully detached from the single body piece 11 and easily displays the inner part of the hinge 13 and the outer part of the hinge 14.

(16) FIG. 7 is a perspective view looking at the invention's 12 side which faces away from the throttle housing 2. FIGS. 7 and 10 shows the pivotable clamp arm's 10 thinner vertical serrated wall 19 and the body piece's 11 vertical serrated wall 22. The vertical serrated walls 19 and 22 are thinner than the overall width of the pivotable clamp arm 10 and the body piece 11, allowing the clamp 10 and body piece 11 to mount in a very small segment of the accelerator sleeve 5 between the throttle housing 2 and the grip 4.

(17) FIG. 8 shows the single button 8 in its properly extended resting position. When this button 8 is pressed in by the operator's thumb, like in FIG. 9, it will be forced back out by a spring-like mechanism housed within the single body piece 11.

(18) FIG. 10-11 show exactly how the stopper 18 protrudes and retracts from the single body piece 11. FIG. 10 shows the stopper 18 completely recessed in the single body piece 11, this is how the stopper 18 rests when the invention 12 is fully disengaged. FIG. 11 shows the stopper 18 protruding from the single body piece 11, this is how the stopper 18 rests when the invention 12 is fully engaged.

(19) FIG. 12 shows the combination 20 of the invention 12 attached to the mounted rotatable accelerator sleeve unit 9, similar to FIG. 3. The marker 21 at the end of the grip is showing the accelerator sleeve 5 in its rested state in FIG. 12. FIG. 13 shows the invention 12 and the mounted rotatable accelerator sleeve unit 9 fully combined 20 but unlike in FIG. 12 where the accelerator sleeve 5 is at rest, FIG. 13 shows the accelerator sleeve 5 rotated back to give the operator a comfortable cruising speed, and the invention 12 is holding the mounted rotatable accelerator sleeve unit 9 in place. The marker 21 in FIG. 13 denotes the rotation of the mounted rotatable accelerator sleeve unit 9 and the cruise control 12 combined 20.

(20) This invention has many advantages over other types of motorcycle cruise controls and throttle locks due to its unique design and function. Some devices require the owner of the vehicle to drill into the throttle housing to mount the device, which may void the vehicle's warranty. Other devices require the owner of the vehicle to mount the device to the handlebar itself, taking up precious space on the handlebar, restricting the use of other safety gear such as hand guards and could block the operator's usage and view of the vehicle controls and dash display. Still, other devices require the owner of the vehicle to mount the device to the bar end of the handlebar, these types of throttle locks activate when the operator grips the device and rotates it as they rotate the throttle to accelerate. This is very dangerous and cumbersome for the rider, especially if they are wearing thick gloves and grab the device unintentionally, thus activating the device inadvertently. None of these previously mentioned devices, nor any others not mentioned here, function by rotating with the operator's hand and throttle as the operator accelerates the vehicle. All of the devices mentioned are mounted in place to either the handlebar, the throttle housing or some other non-rotating part, in order to hold the device as an anchor point. This causes a problem since the operator's hand doesn't remain in the same place while they rotate the throttle. Once they rotate the throttle, their hand will rotate away or towards the fixed controls of the cruise controls. The operator has to adjust their hand according to where the cruise control is located. Every time they change speeds, the controls for the cruise control will be in a different location.

(21) My invention 12 is different. It rotates naturally with the operator's hand and the throttle 5. With my invention 12, the controls 8 of my cruise control 12 will move in unison with relation to the operator's hand as they rotate the throttle 5 between various speeds. This invention's 12 controls 8 will always be perfectly located in relation to wherever the operator places their hand and the throttle 5. This is a great advantage for the operator since they will no longer need to slide their hand around the throttle 5 in order to manipulate the controls 8 of the cruise control 12. My invention 12 does not have an anchor point attached to the handlebars 1. My invention 12 doesn't need the owner to mount it to the throttle housing 2, they simply tighten the clamp 10 and the body piece 11 to the rotatable accelerator sleeve 5. My invention 12 does not cover any portion of the rubber/plastic grip 4, it gives the operator full use of the grip 4, as the manufacture intended.

(22) All visible parts of this invention 12, seen in all FIGS. can be fashioned out of any hard metal or plastic or the like by a CNC process, injection molding, die cast molding or any other parts building machine. The parts within the single body piece 11, which are not visible in the FIGS., can be fashioned from similar materials by the same manufacturing processes common to machine shops and the like.

(23) For proper use of this invention 12 on a vehicle, the operator must first detach the nut and bolt 16 and disjoint the outer hinge 14 from the inner hinge 13, which will completely remove the clamp 10 from the single body piece 11. The body piece 11 will then need to be positioned under the accelerator sleeve 5 between the throttle housing 2 and the grip 4, as in FIG. 3. Now, join the inner hinge 13 and the outer hinge 14 to connect the pivotable clamp arm 10 to the body piece 11, then place the bolt 16 through the clamp's 10 bolt hole 15 and through the body piece's 11 bolt hole 17, then cinch the clamp arm 10 down by tightening the nut and bolt 16 until sufficient pressure is made around the accelerator sleeve 5 between the clamp's 10 vertical serrated wall 19 and the body piece's 11 vertical serrated wall 22. The cruise control 12 is now securely attached to the accelerator sleeve 5 and will not slide side to side or rotate around the accelerator sleeve 5, but will move in conjunction with the accelerator sleeve 5.

(24) To operate the mounted rotatable accelerator sleeve unit 9 to accelerate the vehicle, the operator will need to rotate the accelerator sleeve 5 which in turn accelerates the speed of the engine and the vehicle, as well as turns the invention 12 in perfect rotational unity with the accelerator sleeve 5, since the two parts are now attached to each other. Once the operator has reached the desired speed, they can simply use their thumb to press the button 8 in fully, which engages the invention 12 and forces the stopper 18 to protrude from the body piece 11. Once the operator has fully pressed the button 8 in, the stopper 18 will be held in place by the mechanism inside the body piece 11 and the button 8 will automatically extend out of the body piece 11 back to its proper resting position. Now the cruise control 12 is fully engaged and holding the accelerator sleeve 5 in place by using the friction caused from the stopper 18 pressing against the throttle housing 2. This friction is strong enough to resist the biased spring tension on the throttle cables 3 which is constantly trying to rotate the accelerator sleeve 5 back to its resting position, however, it is not strong enough to resist pressure the operator places on the accelerator sleeve 5 if they choose to override the cruise control 12 and accelerate or decelerate the vehicle with the cruise control 12 fully engaged.

(25) When the operator chooses to disengage the cruise control 12, they need to press the button 8 fully in to allow the mechanism inside of the body piece 11 to retract the stopper 18 into its recessed hole within the body piece 11. Once the button 8 is fully pressed in and the stopper 18 has fully retracted, the button 8 will automatically extend out of the body piece 11 back to its resting position, ready to start the entire cycle over again.
