[57] ABSTRACT The invention is a friction lock which operates upon a throttle hand grip mounted on the steering arm of an outboard motor. An end cap threaded axially with respect to the steering arm urges the hand grip against the shoulder on the steering arm, thereby creating friction to hold the throttle grip in a selected position.
6 Claims, 5 Drawing Figures PATENTEDJAH 11914 SHEEIIUF 2 QIVWARU FRICTION LOCK FOR OUTBOARD MOTOR THROTTLE HAND GRIP BACKGROUND The invention is in the field of outboard motor throttle control devices, and more particularly pertains to means for retaining the throttle in a selected position.
One problem with twisting hand grip throttle controls is that they have a tendency to creep away from a selected setting when the drivers hand is removed from the hand grip. Many are biased to return to the slow speed position when released. This is particularly irritating in those instances where a constant speed is desired, for example, when trolling or running at full power. At the same time, it is undesirable to positively lock a throttle in a set position in such a manner that it cannot be readily adjusted in case of emergency.
It is therefore an objective of the invention to provide a device for locking the twist throttle control hand grip of an outboard motor in any selected position, but in a manner which permits immediate overcontrol in the case of an emergency.
SUMMARY Basically, the invention comprises a cylindrical handle piece adapted to rotate freely upon a cylindrical portion of the steering arm for the outboard motor. An end cap, threaded axially thereto with respect to the steering arm, adjustably abuts the outer end of said hand piece urging it onto the steering arm. Abutment means on the steering arm frictionally engages the inner end of said hand piece increasingly restricting its rotating motion as the end cap is tightened.
Among the advantages of the invention are the ease and speed with which throttle friction adjustments can be made, the simplicity of the structure over prior art throttle grip control linkages and savings which can be affected through the use of synthetic materials and plastics as described herein.
Other objectives, advantages and various further features of novelty and invention will be pointed out or will occur to those skilled in the art from a reading of the following specification in conjunction with the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. I is a top view of an outboard motor steering arm and throttle grip with a friction control device of the invention.
FIG. 2 is a vertical cross section through a side elevation of the handle of FIG. 1 illustrating a throttle friction control mechanism of the invention in the engaged position.
FIG. 3 is similar to FIG. 2 except that the throttle friction mechanism of the invention is illustrated in the disengaged position.
FIG. 4 is a cross section of a throttle control handle of the invention taken along line 4-4 of FIG. 3.
FIG. 5 is an interior end view of an end cap of the invention taken along Line 5-5 of FIG. 3.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. I shows a steering arm I for an outboard motor configured to pivotally engage the motor housing and throttle control mechanisms upon an axis 2 so that it can be raised and lowered. Control of the motor throttle is exercised by twisting a hand grip 3 mounted upon the steering arm 1. Throttle position legends 4, typical of the art, may be provided. As will be explained below, freedom of movement of the hand grip 3 is controlled by adjusting an end cap 5 which causes a frictional force to be exerted upon the body 7 of the hand grip 3.
Referring to FIGS. 2 and 3 the hand grip 3 includes a cylindrical body 7 and an elastomeric outer covering 8. The outer extremity of the steering arm 1 is reduced in diameter forming a basically cylindrical extension 10. The body 7 of the hand grip 3 has a bore 12 therein sized to engage the extension 10 of the steering arm yet freely rotate thereabout. The extension 10 is contoured to create inner and outer annular bearing elements 13 and 14 respectively, which engage and steady the body 7 of the handle grip with the area 15 in between being reduced in diameter so as not to engage the body 7.
In the embodiment of the invention illustrated the end cap 5 is configured to thread upon the outer extremity of a rectangular rod 17 which forms a portion of the throttle control linkage for the motor. The rod 17 extends through an axial bore 16 in the steering arm 1. The bore 16 is enlarged at the inner end 18 to receive therein a portion of a fitting 19 attached to the inner end of the rod 17. The fitting 19 includes an annular shoulder 20 which is engaged by the inner end 21 of a tubular portion 22 of the steering arm 1.
The end cap 5 has an axial bore 25 therein threaded to receive the threaded end 26 of the shaft 17.
In operation, as the end cap 5 is threaded onto the shaft 17, its inner face 27 engages the outer edge 28 of the body 7 of the hand grip 3. As the shoulder 20 on element 19 will prevent outward movement of the shaft 17, further tightening of the end cap 5 will urge the body 7 to the shoulder 11 on the steering arm 1. A washer 29 disposd adjacent the shoulder 11 provides a controlled surface which is frictionally engaged by the inner annular end 30 of the handle body 7. As the handle body 7 and the end cap 5 both turn with the shaft 17, there is no relative motion or friction between the two with a change in power setting.
As best seen in FIG. 4, a bore 31 extending through the outer portion of the handle body 7 is rectangular, as is the shaft 17, so that turning of the grip 3 rotates the shaft 17 and the end cap 5. As the end cap 5 is further tightened, friction between the handle body 7, the washer 29 and the shoulder 11 is increased. Friction between the element 19 and the inner face 21 of the inner annular portion 22 of the steering handle I is reduced by a lubricant.
In the preferred embodiment of the invention it has been found most advantageous to employ certain plastic materials in the manufacture of the body 7, the end cap 5 and the element 19 of the throttle control linkage. Acetal resin plastic such as DuPont Delrin was selected for the handle body 7, the washer 29 and the element 19. Nylon was selected for the end cap 5 and neoprene rubber, impervious to fuels and other solvents, was selected for the handle grip 8. Aside from the fact that these materials offer protection against corrosion, their surfaces are suitable for frictional engagement without excessive wear. Further, the nylon threading within the end cap 5 will deform upon the tightening of the cap and function to resiliently urge the body 7 against the washer 29.
FIG. 3 illustrates the above described assembly with the end cap 5 backed off of the rod 17 so that the handle 3 rides loosely upon the extension of the steering arm 1.
FIG. 4 illustrates certain elements of the internal structure of the handle grip 3. The body 7 has four axial lands 33, 34, 35 and 36 extending from an annular groove 37 in the forward portion thereof (see FIG. 3) to the outer end thereof, the purpose of which is to engage matching detents in the neoprene rubber grip 8 which prevents it from slipping rotationally upon the body 7. The body 7 is reduced in weight by a series of arcuate bores 38, 39, 40 and 41 in the body thereof as illustrated in the drawings.
Referring to FIGS. 3 and 5, the periphery of the end cap 5 and the outer end of the neoprene grip 8 are matchingly stepped. The inner annular edge 51 of the neoprene grip 8 is slightly undersized with respect to its receiving step 52 in the cap 5. The frictional engagement between the surfaces 51 and 52, and the relatively fine nylon threads of the cap, together act to prevent its being vibrated loose during motor operation. This engagement also aids in keeping water and dirt from the interior of the handle. The body of the cap 5 is also reduced in weight by the presence of three arcuate bores 43, 44 and 45 positioned so that the solid annular portions 46 and 47 of the cap 5 engage the solid annular portions 48 and 49 of the handle body 7 when the cap 5 is tightened.
The invention thus presents a simple and effective means for creating and varying frictional restraint to the movement of the throttle grip 3 about the steering arm I, and thereby controlling movement of the throttle linkage shaft 17. It will be apparent to those skilled in the art that retaining shaft 17 in a selected position will effectively maintain the engine throttle at a corresponding position.
From the foregoing it can be seen that while sufficient frictional force can be brought to bear upon the grip 3 to prevent its turning, that no mechanical lock is applied so that should the operator choose he can vary the throttle setting simply by exerting sufficient rotational force to overcome the restraining frictional force.
While the principles of the invention have been described in connection with the above specific apparatus, it is to be clearly understood that this description is made only by way of example and not as a limitation to the scope of the invention.
