Blair - Inventors: Charles Blair - Web page: https://patentgrep.com/patent/US20060189226A1 ## CPC - B63H 21/213: {Levers or the like for controlling the engine or the transmission, e.g. single hand control levers} - B63H: MARINE PROPULSION OR STEERING (propulsion of air-cushion vehicles B60V1/14; specially adapted for submarines, other than nuclear propulsion, B63G; specially adapted for torpedoes F42B19/00) ## Abstract A torsional throttle control system is provided that may include any of a number of features. One feature of the throttle control system is twist-style grip that has an axis with an angle adjustable to a housing. Another feature comprises trim and/or outboard motor control(s) atop the grip. Yet another feature comprises the internal mechanism adapted to effect throttle control. Methods associated with use of the throttle control hardware and systems including a boat are also covered. ## Claims ### Claim 1 A throttle control comprising: a twist handle, the handle connected to a shaft with a first bevel gear toward a distal end of the shaft, a second bevel gear meshing with the first bevel gear, wherein rotation of the handle about an axis of the shaft provides an output from the second bevel gear for throttle control, and wherein an axis of the twist handle is adjustable relative to a fixed housing. ### Claim 2 (depends on 1) The assembly of claim 1, wherein the shaft includes a U-joint. ### Claim 3 (depends on 1) The assembly of claim 1, wherein the shaft is adjustable between about 15 and about 90 degrees. ### Claim 4 (depends on 1) The assembly of claim 1, wherein the second bevel drives a pinion gear meshing with a rack gear, and the rack gear provides an output travel for the device. ### Claim 5 (depends on 1) The assembly of claim 1, wherein the pinion gear comprises a sector, wherein a ball detent interfaces with detent positions spaced around the sector. ### Claim 6 (depends on 1) The assembly of claim 1, a detent means is provided for the handle adjustment. ### Claim 7 (depends on 1) The assembly of claim 1, further comprising at least one of trim and motor up/down buttons atop the handle. ### Claim 8 (depends on 1) The assembly of claim 1 set in a housing, the housing further comprising a gear shifter. ### Claim 9 (depends on 1) The assembly of claim 1, further comprising a cable, the cable connected to a rack gear meshing with a pinion gear, the pinion gear positioned to actuate fuel supply to an engine or motor. ### Claim 10 A throttle control, the controller having a rotatable handle to control engine or motor throttle, wherein the improvement consists of: the grip having an axis, wherein the axis is adjustable to a base at an angle without effecting steering. ### Claim 11 (depends on 10) The throttle control of claim 10, comprising a u-joint to allow for adjustment. ### Claim 12 (depends on 10) The throttle assembly of claim 10, wherein a detent means is provided for the adjustment. ### Claim 13 (depends on 10) The throttle assembly of claim 10, wherein a position of the grip can be locked at a desired point of adjustment. ### Claim 14 A throttle control, the controller having a rotatable handle to control engine or motor throttle, wherein the improvement consists of: at least one of a trim and an outboard up/down buttons atop the handle. ### Claim 15 (depends on 14) The throttle control of claim 14, wherein the handle has an ergonomic shape substantially as shown in FIG. 2A. ### Claim 16 (depends on 1, 10, 14) A boat comprising: a hull, at least one motor, and a throttle control selected from one of the throttle controls described in claims 1, 10 or 14 mounted to or integrated with the boat. ### Claim 17 A method of operating a boat by a user having first and second hands, the method comprising: grasping a steering wheel with the first hand one hand, grasping a throttle control with the second hand, and substantially maintaining a body position while effecting throttle control by supporting the body from forward and aft movement with the wheel and throttle control. ### Claim 18 (depends on 17) The method of claim 17, further comprising adjusting at least one of trim and motor up/down without substantially altering the second hand position. ### Claim 19 A method of operating a boat by a user having first and second hands, the method comprising: grasping a throttle control with the first hand, and adjusting at least one of trim and motor up/down with the hand while grasping the throttle control. ### Claim 20 (depends on 19) The method of claim 19, further comprising grasping a steering wheel with the second hand while grasping the throttle control with the first hand.
