Description
Summary of the Invention
Fishing boats and other outboard motor powered boats are frequently steered from behind by rotation of the motor upon turning of the conventional steering arm associated with the motor. This puts the fisherman or other boat man in awkward position of reaching at least partially rearward to steer the boat. It also occupies his hands to the exclusion of other activities such as tending fishing equipment.
The invention pertains to a foot operated steering apparatus for steering a boat having an outboard motor mounted on a transom thus to free the hands of the fisherman or boatman to perform other activity and also to enable the boatman to position himself more centrally in the boat if desired.
The apparatus includes a pair of longitudinal parallel spaced apart side frame members positioned on the floor or bottom of the boat. A platform is fastened to the side frame members and carries a horizontally disposed rotatable turntable. A steering cable is trained over a grooved rim of the turntable, extending rearwardly therefrom and eventually connected to the outboard motor. Foot pedals are rotatably mounted to a cross member extending between the longitudinal frame members and are associated with the turntable such that the depression of either a right or a left foot pedal by a fisherman seated on a boat seat is operative to turn the turntable and pull the steering cable to turn the boat in either a right or a left direction. The length of the side frame members is adjustable for installation in different lengths of boats. An adjustable rear cross brace assists in holding the frame members in place with respect to the boat.

Referring to the drawings, there is shown in FIGS. 1 and 2 a foot operated steering apparatus indicated generally at 10 according to the present invention installed in a boat 11 of the type propelled by outboard motor 12 fixed by motor clamps 13 on the transom 15 of boat 11. Outboard motor 12 propels boat 11 through the water and boat 11 is steered by rotation of outboard motor 12 relative to clamp assembly 13 about a generally upright axis in a direction opposite the intended direction of travel of boat 11. Boat 11 has a floor or bottom 16 joined to upwardly extended longitudinal sides 17, 18. A plurality of transverse seats 20, 21, 22 span the beam of boat 11 and are interiorly connected to sides 17, 18. A fisherman or other boat person can sit on one of the seats 20 and manipulate the foot operated steering apparatus 10 to turn the outboard motor 12 and steer boat 11 while having free hands for performing other functions.
Steering apparatus 10 includes a pair of first and second longitudinal, parallel spaced apart side frame members 23, 24 located on floor 16 of boat 11 extended from proximate the stern thereof to an intermediate location along the center line of boat 11. Forward ends of frame members 23, 24 are connected by a cross member 26. Frame members 23, 24 can be comprised of telescopically engaged tubular sections so as to be extendable and retractable in length and held in position by clamp assemblies 27, 28. As shown in FIG. 4, second frame member 24 includes a first hollow tubular section 24A and a second tubular section 24B telescopically engaged in the forward end of the first tubular member 24A. Clamp assembly 28 includes a nut 29 secured to the surface of the first tubular section 24A near the end thereof. A bolt 30 is threaded into the nut 29 and through a corresponding opening provided in the first tubular section 24B engaged therein to hold it in place. Bolt 30 is readily releasable for adjustment of the length of frame member 24. First frame member 23 is likewise adjustable.
The aft or rearward ends of side frame members 23, 24 are connected as by welding or the like to a tubular cross brace 32. Cross brace 32 comprises an open ended tubular member disposed transversely of the center line of bolt 11 and has legs 33, 34 telescopically engaged in either end and extending outward thereof. The legs 33, 34 terminate and feet 35 to bear against the inside surfaces of sidewalls 17, 18 of bolt 11. Clamp assemblies 37 located on the cross brace 32 are effective to clamp or lock the outwardly extended position of the legs 33, 34 with the feet 35 bearing against the interior surfaces of the boat walls 17, 18 to facilitate holding the frame members 23, 24 in place. Longitudinal brace members 38, 39 are connected to cross brace 32 and extended rearwardly therefrom to a point in surface engagement with the interior surface of transom 15 to further inhibit rearward movement of longitudinal side frame members 23, 24.
A horizontal plate or platform 41 is disposed between side frame members 23, 24 toward the forward ends thereof and is suitably secured to them as by welding. A circular, horizontal turntable 42 is rotatably mounted on the upper surface of platform 41. Referring to FIG. 5, platform 41 carries a suitable bearing assembly 43. A shaft 44 extends from the bearing assembly 43 and is centrally secured to the turntable 42 for rotational movement of turntable 42 about a generally vertical axis as indicated by the arrow 45 in FIG. 1.
A pair of first and second or left and right foot pedals 48, 49 are provided for rotation of turntable 42. A transverse mounting rod 50 is disposed between the longitudinal side frame members 23, 24 a distance slightly behind platform 41. As shown in FIG. 2, right foot pedal 49 has a rearward boss 51 secured to its lower surface and in pivotal engagement with the mounting rod 50. Foot pedal 49 is orientated in an upwardly inclined disposition and has a forward boss 52 mounted on its forward lower surface. Forward boss 52 is pivotally connected to one end of a foot pedal link 54. A transverse steering arm 55 is secured to turntable 42 and extends laterally across its upper surface. The opposite end of foot pedal link 54 is pivotally connected to one end of the transverse steering arm 55. Depression of foot pedal 49 is effective to rotate the turntable 42 in a counterclockwise direction as viewed in FIG. 1. In similar fashion, the left foot pedal 48 is connected by another foot pedal link 56 to the opposite end of the transverse steering arm 55 on the opposite side of the axis of rotation of turntable 42 such that depression of the left foot pedal 48 is effective to rotate the turntable 42 in a clockwise direction as viewed in FIG. 1. As shown in FIG. 5, arm 55 has an undercut groove 55A. Links 54 and 56 have heads that fit into the groove 55A to pivotally connect the links to the arm.
A steering cable 58 is trained around the forward perimeter of turntable 42 and extends rearwardly from either side of turntable 42. The perimeter of rim of turntable 42 is provided with a groove 59 for accommodation of cable 58 (see FIG. 5). Cable 58 extends tangentially from either side of turntable 42 rearwardly and parallel to side frame members 23, 24. One side 58A of cable 58 extends proximate and parallel to the first frame member 23 and is trained through a first pulley 60 fixed to the aft end of frame member 23. Cable side 58A extends from pulley 60 to a second pulley 61 fixed to the transom 15 on the opposite side of the center line of boat 11 with respect to the first pulley 60. Cable side 58A is trained through pulley 61 and then extends to motor 12. The second side 58B of cable 58 extends tangentially from turntable 42 proximate to and parallel to the second side frame member 24 and is trained through a third pulley 62 fastened to the aft end of the second side frame member 24. Cable side 58B extends from the third pulley 62 to a fourth pulley 63 fastened to the transom 15 of boat 11 and located on the opposite side of the center line of boat 11 relative to the third pulley 62. Cable sides 58A, 58B cross one another proximate the center line of boat 11 and proximate motor 12. Second cable side 58B is trained through the fourth pulley 63 and then extends to the motor 12.
Referring to FIG. 6, motor 12 has a conventional handle 65 having a closed loop clip 66 attached thereto. The end of cable side 58A is fastened to a first cable clamp 67. Cable clamp 67 is of a conventional releasable variety whereby the length of cable 58A can be adjusted. Cable clamp 67 is attached to a first tension spring 68 having a hooked end. The hooked end of tension spring 68 engages the clip 66 on handle 65. Second cable side 58B is fastened to a second cable clamp 70. Second cable clamp 70 is attached to a second tension spring 71 having a hooked end which is also engaged in the clip 66. Adjustment of the length of cable sides 58A, B so that there is tension in tension spring 68, 71 is effective to put a desired amount of tension in steering cable 58.
In use, a boatman is seated on seat 20 with feet engaging the foot pedals 48, 49 while motor 12 is operating. Depression of the right foot pedal 49 is effective to turn the boat in a right hand direction. As can be seen schematically in FIG. 3, depression of the right foot pedal 49 is effective to rotate turntable 42 in a counterclockwise direction as viewed in FIG. 3. This pulls the second side of 58B of cable 58, and through third and fourth pulleys 62, 63, the motor 12 is rotated in counterclockwise direction as viewed in FIG. 3. This is effective to turn boat 11 to the right. Depression of the left foot pedal 48 in like fashion is effective to turn the boat 11 to the left. The steering apparatus 10 is readily removable from boat 11 for placement in another boat. The frame members 23, 24 are adjustable in length so as to be fitted in boats of varying lengths. Likewise, the legs 33, 34 of cross brace 32 are extendable and retractable so as to be able to fit in boats of varying widths.
A modification of the foot power transmission assembly or drive, indicated generally at 75, is shown in FIG. 7. Assembly 75 has a first disc or pulley 76 rotatably mounted on an axle or fixed shaft 77. Axle 77 is secured to a cross plate 78 secured to frame members 23 and 24. A second disc or pulley 79 rotatable mounted on shaft 44 is secured to turntable 42. Pulley 79 has a diameter of about one-half of the diameter of pulley 76. Other size ratios between pulleys 76 and 79 can be used. A cable 81 is trained about pulleys 76 and 79 drivably connects the pulleys. A gear drive can drivably connect pulley 76 with pulley 79. Foot pedals 48 and 49 pivotally mounted on transverse rod 50 are connected to links 56 and 54, respectively. The forward ends of links 54 and 56 are located in grooves 82 and 85 in opposite sections of pulley 76. The links 54 and 56 are pivotally connected to pulley 76 so that the foot pedals 48 and 49 when depressed selectively rotate pulley 76 in opposite directions. Cable 81 transmits this rotational movement to small pulley 79 with an increase in torque. Pulley 42 moves cable 58 which turns motor 12.
While there has been shown and described several embodiments of a steering apparatus according to the invention, it will be apparent that variations and deviations can be had from the embodiments shown without departing from the scope and spirit of the invention.
