Abstract

Abstract An improved steering device for a marine propulsion unit that incorporates a steering bracket that is clamped to the transom of the associated watercraft in proximity to the tilt axis of the outboard drive. A steering rod is reciprocally supported in a bore in the steering bracket and is connected at one end to a push pull cable and at the other end to the steering arm of the outboard drive for effecting its steering.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 212 words
A steering device for a marine propulsion device affixed relative to the transom of a watercraft, said propulsion device comprising a drive shaft housing rotatably journaling an engine driven shaft, a swivel bracket journaling said drive shaft housing for steering movement about a generally vertically extending steering axis, a generally "C" shaped clamping bracket adapted to receive the upper end of the transom for affixing said propulsion device to the transom, pivot pin means interconnecting said swivel bracket and said clamping bracket for pivotal movement about a generally horizontally extending tilt axis, and a steering arm affixed to said drive shaft housing, the improvement comprising a steering bracket affixed between a downwardly extending face of said clamping bracket and an upwardly extending face of the transom, said clamping bracket extending over said steering bracket for direct attachment to the transom, said steering bracket defining a bore extending generally parallel to and offset from said tilt axis, a steering rod slidably supported in said bore for reciprocation relative thereto, means for affixing an operator controlled steering cable to said steering rod for effecting operator controlled reciprocation of said steering rod, and means connecting said steering rod to said steering arm for steering of said drive shaft housing upon reciprocation of said steering rod.
Claim 2
Dependent Claim 212 words
A steering device for a marine propulsion device affixed relative to the transom of a watercraft, said propulsion device comprising a drive shaft housing rotatably journaling an engine driven shaft, a swivel bracket journaling said drive shaft housing for steering movement about a generally vertically extending steering axis, a generally "C" shaped clamping bracket adapted to receive the upper end of the transom for affixing said propulsion device to the transom, pivot pin means interconnecting said swivel bracket and said clamping bracket for pivotal movement about a generally horizontally extending tilt axis, and a steering arm affixed to said drive shaft housing, the improvement comprising a steering bracket affixed between a downwardly extending face of said clamping bracket and an upwardly extending face of the transom, said clamping bracket extending over said steering bracket for direct attachment to the transom, said steering bracket defining a bore extending generally parallel to and offset from said tilt axis, a steering rod slidably supported in said bore for reciprocation relative thereto, means for affixing an operator controlled steering cable to said steering rod for effecting operator controlled reciprocation of said steering rod, and means connecting said steering rod to said steering arm for steering of said drive shaft housing upon reciprocation of said steering rod.
Claim 3
Dependent Claim 23 words
A steering device as set forth in claim 1 wherein the steering bracket is clamped to the transom independently of the clamping bracket.
Claim 4
Dependent Claim 29 words
A steering device as set forth in claim 2 wherein the steering bracket is affixed to the transom on the opposite side of the transom from the clamping bracket.
Claim 5
Dependent Claim 24 words
A steering device as set forth in claim 2 wherein the steering bracket forms a piece separate from the transom and the clamping bracket.
Claim 6
Dependent Claim 21 words
A steering device as set forth in claim 4 wherein the steering bracket has a recess for receiving the clamping bracket.
Claim 7
Dependent Claim 29 words
A steering device as set forth in claim 5 wherein the steering bracket is affixed to the transom on the opposite side of the transom from the clamping bracket.
Claim 8
Dependent Claim 28 words
A steering device as set forth in claim 1 wherein the axes of the bore and that defined by the pivot pin are disposed closely adjacent each other.
Claim 9
Dependent Claim 21 words
A steering device as set forth in claim 7 wherein the bore axis is disposed rearwardly and below the tilt axis.
Claim 10
Dependent Claim 27 words
A steering device as set forth in claim 1 further including means for affixing one end of a push-pull cable to one end of the steering rod.
Claim 11
Dependent Claim 25 words
A steering device as set forth in claim 1 wherein the means for connecting the steering rod to the steering arm comprises a steering link.
Claim 12
Dependent Claim 22 words
A steering device as set forth in claim 10 wherein the steering link is affixed to one end of the steering rod.
