1. Field of the Invention

This invention relates to water craft. This invention further relates to an apparatus for steering control of water craft by operator body motion commands.

2. Background of the Invention

Water craft with outboard motors are commonly used for recreational fishing in rivers and lakes. The outboard motors are electric or gasoline driven. One type of fishing, called trolling, requires the operation of the outboard motor while fishing. When trolling, the operator is compelled to steer the craft while fishing. Understandably, the operator, holding the fishing rod, will find it difficult to steer the craft and fish at the same time. Prior to my invention, trolling usually required setting the motor in a first desired direction along a first desired track. When the operator desires to change to a second direction and track, it is necessary to suspend fishing operations and direct fill attention to the outboard motor. Clearly, this disruption of fishing operations leads to a lessened enjoyment of the sport.

Therefore, it is desirable to have an apparatus that can be used for trolling that does not require the disruption of fishing operations to steer the craft.

OBJECTIVES OF THE INVENTION

It is an object of the present invention to provide an apparatus for steering control of a water craft by operator body motion commands.

It is a further objective of the present invention to provide an apparatus for steering water craft that does not require the operator to suspend fishing operations in order to change the direction of the water craft.

SUMMARY OF THE INVENTION

My invention is an apparatus for steering control of a water craft by operator body motion commands. The water craft has at least one flat hull cross-member having an upper surface and is propelled by an outboard motor having a first vertical axis. The apparatus comprises a swivel seat for accepting said body steering commands. The seat comprises swivel means for rotation about a second vertical axis and a bottom surface. The swivel seat has a first disengaged mode wherein the body motion commands are not transmitted to the outboard motor; and, a second engaged mode wherein the body motion commands are transmitted to the outboard motor. Also included are means for moving the swivel seat from the first disengaged mode to the second engaged mode and back again to the first disengaged mode. The invention includes means for transmitting the body motion commands to the outboard motor, whereby the body motion commands are translated into steering commands causing the outboard motor to pivot in a desired direction about the first vertical axis.

Swivel means comprises a first swivel co-axial with the second vertical axis and mounted by mounting means to the at least one flat hull cross-member upper surface; and, a second swivel coaxial with the second vertical axis and mounted by mounting means between the first swivel and the bottom surface of the swivel seat.

Engagement means comprises a first control member having a first end and a second end. The first control member first end is mounted by mounting means between the first swivel and the swivel seat bottom surface. There is a slotted sleeve fixed to the first control member second end. There is also a second control member having a first end and a second end. The second control member first end is mounted by mounting means between the first swivel and the second swivel. The second control member second end has an aperture and this aperture is co-axial with the slotted sleeve. A retractable biased engagement pin is slidably mounted within the slotted sleeve. The pin has an engagement end. The pin further has a first retracted position wherein the engagement end of the pin is disengaged from the aperture. This results in the swivel seat being in its first disengaged mode. In the second engaged position, the pin engagement end is engaged with the aperture thereby coupling the first control member to the second control member. This results in the first and second control members rotating dependently so that rotation of the swivel seat about the second vertical axis causes identical rotation of the second control member about the second vertical axis.

Means for transmitting the body motion commands to the outboard motor comprise a connecting member having a first end and a second end. The first end is connected by first connecting means to the second control member. The second end is connected by second connecting means to the outboard motor so that movement of the second control member about the second vertical axis is transmitted by the connecting member to the outboard motor and translated into sympathetic movement of the outboard motor about the first vertical axis.

The first swivel comprises a first upper mounting plate, a first lower mounting plate mounted to the hull cross-member upper surface; and, a first circular bearing track disposed between the first lower mounting plates and the first upper mounting plate. The first circular bearing track includes a first plurality of bearings permitting rotation of the first lower mounting plate with respect to the first upper mounting plate. The second swivel is similarly constructed.

Construction of the swivel seat comprises a horizontal seating platform having a left side and a right side. The horizontal seating platform is contoured for receiving the buttocks of an operator. There is also an upward sloping left side member fixed to the left side of the horizontal seating platform. The left side member is adjacent to the left thigh of an operator and contoured to receive the contour of the left thigh of an operator.

The stern includes a transom member (24) adapted to mount an outboard motor (26). The outboard motor can be an electric trolling motor or a small gasoline driven motor. The motor has a vertical shaft casing (28) in which the drive shaft of the motor is contained. The shaft casing rotates about a first vertical axis (29). The drive shaft is connected by a transmission (30) to a propeller (32). The small craft includes at least one flat hull cross-member (34) acting as a seat. The at least one flat hull cross-member (34) has an upper surface (38), a first length (40) and a first width (42).

Referring now to FIGS. 5 to 8, the apparatus of my invention (10) comprises a swivel seat (44) having swivel means (45) permitting rotation of the seat (44) about a second vertical axis (46). The swivel seat (44) has a bottom surface (81). Swivel means (45) is mounted by mounting means to the upper surface of flat hull cross-member (34). Throughout the detailed description of my invention “mounting means” typically comprise a nut, bolt and washer combination. In another embodiment of the invention, the hull cross-member may be a separate rectangular member which can be temporarily and releasably fixed to the hull cross-member (34) by temporary mounting means such as clamps. The seat (44) is adapted to receive body motion commands from an operator as more fully explained below.

The apparatus of my invention has a first disengaged mode wherein the body motion commands of the operator are not transmitted to the outboard motor. The apparatus of my invention also has a second engaged mode wherein the body motion commands of the operator are transmitted to the outboard motor. Engagement means are included for moving the apparatus from the first disengaged position to the second engaged position. Means are provided for transmitting body motion commands of the operator to the outboard motor which cause the outboard motor to pivot in the desired direction about the first vertical axis.

Still referring to FIGS. 5 to 8, there is provided a more detailed description of the swivel seat (44) of my invention (10). The swivel seat (44) comprises a generally horizontal seating platform (56) having a left side and a right side. The seating platform may be contoured to more comfortably accept the buttocks of an operator. Alternatively, there may be a cushion fixed to the horizontal seating platform (56) for operator comfort. The seating platform (56) has a leading edge (60) having a sinusoidal contour that is adapted to comfortable accept the back thighs of an operator and, as well, to facilitate the swivel motion of the swivel seat by providing an abutting surface (at 60) between the legs of the operator for left and right swivel motions of the swivel seat.

In order to translate body motion of the operator into swivel motion of the swivel seat (44), the swivel seat includes a first upward curving left side member (64) fixed to the left side of the horizontal seating platform (56). The first curving left side member (64) has an inwards concave surface to better fit against the substantially convex contour of the left thigh of an operator. The first curving left side member (64) has a first top surface (68) to act as an arm rest and a first skirt (70) depending down from the first arm rest (68). The first skirt (70) and first top surface (68) create a first hollow (71) that may be used for grasping by the operator. Similarly, on the right side (22) of the swivel seat (44) there is a second upward curving right side member (72) fixed to the right side of the horizontal seating platform (56). The second curving right side member (72) has an inwards concave surface to better fit against the substantially convex contour of the right thigh of an operator. The second curving right side member (72) has a second top surface (74) adapted to act as an arm rest and a second skirt (76) depending from the second top surface (74). The second top surface (74) and the second skirt (76) act together to form second hollow (78) that may be used for grasping by an operator. The swivel seat (44) further includes a third upward curving back member (80) disposed between the left upwardly curving side member (64) and the right upward curving side member (72). The upward curving back member (80) is adapted to conform to the lower back and buttocks of an operator. The horizontal platform (56), left side member (64), right side member (72) and back member (80) are moulded from a suitable thermoplastic material from a single mould and form a single piece.

The pin member is engaged in a second engagement location into aperture (240). Similarly, if the operator wishes to swivel the swivel seat 30 degrees to left the pin member (300) can be engaged in a third engagement location into aperture (242).

Referring now to FIGS. 1 to 4 and to FIG. 16, 1 will now describe the means for transmitting body motion commands from the swivel seat (44) to the outboard motor (26). In FIG. 16, there are shown three views (A, B and C) of connecting member (51) having a first threaded end (450) and a second threaded end (452). There is also a first bracket (454) for connecting the connecting member (51) first threaded end (450) to the second control plate (200) and a second bracket (456) (identical to the first bracket illustrated in FIG. 17) for connecting the connecting member (51) second threaded (452) end to the outboard motor (26).

Referring now to FIG. 17, there are shown multiple views (side, A; top B; and perspective C) of one embodiment of the bracket (454). Bracket (454) comprises a base (462) having a threaded aperture (464) adapted to receive the connecting member threaded ends (450) and (452). There is also a first tine (466) fixed to the base (462). The first tine has a first arcuate free end (468) and a first tine first aperture (470). There is also a second tine (472) fixed to the base (462) opposite to and parallel to the first tine (466). The second tine has a second arcuate free end (474) and a second tine second aperture (476).

Referring to FIG. 18, there is illustrated first means for connecting the connecting member first threaded end to the second control member. Bracket (454) is adapted to receive the left side of the control plate (200) between the first and second tines. The first tine first aperture (470) and the second tine second aperture (476) are co-axially aligned with the control plate third aperture (228) or alternatively control plate fourth aperture (232). A pin member (480) adapted for quick releasable placement within the co-axially aligned first tine first aperture, second tine second aperture and control plate third aperture is inserted thereby fixing the connecting member (51) to the second control plate.

Referring to FIG. 19, there is illustrated second means for connecting the connecting member threaded second end to the outboard motor (26). There is a second bracket (456) comprising a second base (492) having a second threaded aperture (494) adapted to receive connecting member threaded end. There is a third tine (496) fixed to the second base with an arcuate free end and an aperture. There is a fourth tine (498) fixed to the second base opposite to and parallel to the third tine. The fourth tine has a fourth arcuate free end with a fourth tine fourth aperture.

Since both ends of the connecting member (51) are threaded into a bracket the tension in the connecting member can be adjusted by threading more or less of the threaded ends of the connecting member into the bracket. As well, the connecting member has a contoured shape to permit transmission of movements from the swivel seat (44) to the outboard motor (26) in an offset manner.

Referring to FIG. 19 and FIG. 20, there is shown a bracket arm (500) having a longitudinal axis (502), a first half (504) and a second half (506). The first half has at least two apertures (512) and (514) positioned vertically. The second half has at least two apertures (508) and (510) positioned vertically. There is also one threaded longitudinal bore (516) adapted to receive threaded rod (520). Friction clamp (522) is adapted to clamp around the vertical shaft casing (524) of the outboard motor (26). The friction clamp (522) has a collar portion (526) adapted to frictionally engage the vertical shaft casing and two adjacent and parallel arms (528) and (530 not shown) apertured to receive threaded rod (520). There is a nut (532) adapted for threaded engagement onto the threaded rod so that the two adjacent and parallel arms are between the nut and the bracket second end. When the nut is rotated towards the bracket second end the two adjacent and parallel arms are compressed together thereby tightening the collar about the vertical shaft casing. A quick release pin (540) is provided for pinning the bracket first end between the third tine and the fourth tine in a pivoting engagement.

Referring back to FIG. 9, when the swivel motion of the swivel seat (44) is fixed with respect to the swivel motion of the control plate (200), arm (600) is used to control the direction of the swivel seat and as well the movement of the outboard motor. Arm (600) comprises shaft (602) having a first end (604) and a second end (606). Attached to the second end (606) is hand control knob (608) used by the operator to push the shaft bow ward or stem ward. The first end (604) is placed into shaft receiver (610) welded to the bottom surface of control member (200).

Referring now to FIG. 21, there is shown a diagram of the operation of my invention with the pin member (300) disengaged from control member (200). When the pin member (300) is disengaged from control member (200) first swivel body (90) and second swivel body (92) are free to swivel with respect to each other. Therefore, swivel seat (44) is free to swivel in any direction and cannot be used to direct the boat. The body motion steering control apparatus is disengaged. The arm (600) can be used to direct the craft in a desired direction or alternatively, the operator can swivel the swivel seat-towards the stem and control the direction of the boat using the arm (25) of the outboard motor (26). If the operator wishes the boat to go to the left the arm (600) is moved towards the bow (16) of the boat. This motion is transmitted by connecting member (51) in a pulling motion as indicated by arrows (700) side and the outboard motor (26) is turned so that the propeller (710) swings to the left pushing the bow of the boat to the left. If the operator wishes the boat to go to the right the arm (600) is moved towards the stern (18). The motion is transmitted by connecting member (51) as a pushing motion as indicated by arrows (730) and the propeller is forced to the right. The bow is then driven to the right.

Referring now to FIG. 22, the control pin (300) is engaged with control member (200). When the control pin is engaged the body motion steering control apparatus is engaged. First swivel body (90) is fixed and second swivel body (92) is permitted rotational movement. Therefore, only the swivel seat (44) may swivel with respect to mounting member (34). The swivel seat (44) can be used by the operator to impart motion to the propeller in order to direct the boat. In FIG. 22, if the operator swivels the seat to the right the swivel motion is transmitted by connecting member (51) to the motor as a pushing motion as indicated by arrows (734). This pushing motion causes the propeller on the motor (26) to turn to the right as shown by arrow (736) pushing the bow of the boat to the right. If the operator wishes the boat to move to the left, the operator swivels the swivel seat to the left this causes a pulling motion in connecting member (51) as indicated by arrows (830) causing propeller to move to the left as indicated by arrow (732). This pushes the bow to the left.

By using the swivel seat, the operator is able to troll at low speeds while fishing and use body motion to swivel the seat to the left or the right in order to direct the boat. This is a preferred hands free operation allowing the operator to concentrate on the sport. As previously noted, the operator can lock the swivel seat 30 degrees to the left or the right permitting the operator to face the desired side of the boat while using body motion to steer the boat.

Other embodiments of my invention are contemplated. For example, the arm (600) and shaft receiver (610) shown on FIG. 9 may be a single piece of solid, half inch round aluminum rod, welded to the control member (200).

In another embodiment of the invention, the first control member (150) can have the same dimensions as the second control member.

In still another embodiment of my invention, an optional bracket can be attached to the swivel seat (44) having control means to control the operation of the motor, such as start-stop and throttle.

Although this description has much specificity, these should not be construed as limiting the scope of the invention but as merely providing illustrations of some of the presently preferred embodiments of this invention. Thus the scope of the invention should be determined by the appended claims and their legal equivalents, rather than by the examples given.
