DESCRIPTION OF THE INVENTION
U.S. Pat. No. 9,290,251 and U.S. patent application Ser. No. 14/791,926 filed Jul. 6, 2015 are incorporated herein by reference.
Referring to the drawings wherein like numerals indicate like elements, there is shown in FIG. 1, a watercraft 10 having a bow 12, stern 14, and a cockpit 16. In this embodiment, the trolling motor system 20 is affixed to the stern. The watercraft may be any light-weight watercraft, but it may be a kayak or canoe. If a kayak, it may be a single or tandem kayak with or without an open top.
The motor system 20 generally includes: a mounting system 22; a winch 30; a guidance mechanism 32; and a motor 34.
The mounting system 22 is attached to the watercraft. The mounting system 22 connects the motor, winch, and guidance system to the watercraft. The mounting system allows, when attached to the watercraft and the winch is rigidly affixed (e.g. versus the wire used with the electrical winch shown in U.S. Pat. No. 9,290,251) to the moveable end of the plate, the motor system to “bounce” (e.g., flex up and down), for example, when the a part of the motor system strikes a submerged object. The mounting system also facilitates the placement and removal of the motor system on the watercraft.
The mounting system 22 generally includes a bracket 21 and a plate 23, see FIGS. 2-5. The bracket 21 includes a connector 25 that removably joins the bracket to the watercraft. The plate 23 includes a first end 24, a moveable end 26, a hinge 28 therebetween. A pivot 27 connects the bracket 21 to the first end 24 of the plate 23 and allows the motor system to bounce. The moveable end 26 extends away from the stern 14 and hangs outside watercraft 10. Hinge 28 allows the movement of the moveable end (as will be discussed in greater detail below). The fixed end may include a stop 29 to prevent the downward movement of the moveable end 26 beyond a predetermined position (e.g., a horizontal plane).
The connector 25 may be any connector. The connector facilitates a universal connection between any style watercraft and the motor system. The connector allows movement between the bracket and the watercraft in multiple planes. In one embodiment, the connector 25 is a double ball joint. One ball (or a pair of balls) is affixed to the watercraft, the other ball (or pair of balls) is affixed to the bracket, and a socket (or clamp) interconnects the watercraft ball to the bracket ball. In other embodiments, the connector may be made of screw, bolts, clevis pins or the like.
Winch 30 may be mounted to (or affixed on) the fixed end 24 and thereby may be mounted on the stern 14. Winch 30 may be any device that is capable of raising and lowering, in a controlled manner, the distal end of the moveable end 26. Winch 30 may be: an electrical winch; a linear actuator, e.g., worm gear device; and/or hydraulic actuator. Winch 30 is coupled to a distal end of the moveable end 26, so that the winch may raise and lower the moveable end 26 between an upper and lower position, see generally FIGS. 6-8. In the embodiment, the winch is directly coupled with the moveable end (i.e., no intervening pulleys or linkages between the winch and moveable end). Springs (e.g., coil springs), not shown, interconnecting (i.e., spanning across the hinge) the fixed end and moveable end may be used to lessen shock during and/or facilitate movement between the up and down position. If the winch 30 is the actuator (linear or hydraulic), the coupling of the moveable end 26 of the plate to the free (or moveable) end of the actuator may prevent movement of the hinge 28; so pivot 27 allows the motor system to bounce. Operation of the winch may be controlled by a switch located at the winch or remotely from the cockpit.
Guidance mechanism 32 may be mounted to and below moveable end 26. Guidance mechanism 32 is rotationally affixed to the moveable plate 26, so that it may swing back and forth (oscillate) in a horizontal plane, see FIGS. 9-12. This movement may be about a pivot point, for example, pivot 44 and bracket 48, see FIG. 14. Guidance mechanism 32 may include a pair of laterally extending wings 33, see FIGS. 9-11. Wings 33 are aligned with pivot 44. Wings 33 are coupled to steering mechanism.
The steering mechanism may be any steering mechanism, for example, pedal operated (discussed below), joystick, rack and pinion, steering wheel, power-assisted, and the like. In the embodiment shown, the steering mechanism allows the user to forward (i.e., without any body twist or reaching backward during steering). As shown, the steering mechanism may include a wire guidance mechanism 40. Wires 40 connect the wings 33 to the cockpit from where the user steers the watercraft. These wires 40, in one embodiment, may extend within the hull of the watercraft (note the phantom lines, for example see FIGS. 9-13). As shown, the steering mechanism may, for example, include a pair of pedals 42 (for example, running in a horizontal track within the watercraft), but the steering mechanism is not so limited. With the pedals 42, the user steers the watercraft with their feet, see FIGS. 12 and 9-11.
Motor 34 may be affixed to and below and moves with the guidance mechanism 32 (as a single unit, i.e., when the guidance mechanism moves the motor moves). In the embodiment shown, motor 34 may be spaced below guidance mechanism 32 with a vertical plate (or rudder) 35. Motor 34, when in the down position, see FIG. 8, is submerged below the water line. Motor 34 may be an electric motor. Motor 34 may be a variable speed motor. Motor 34 may be reversible. Motor 34 includes a propeller. The propeller may be directly coupled to the motor (i.e., direct drive or with no linkage nor transmission between the motor and propeller).
A quick release mechanism 38 may couple the moveable plate 26 to the guidance mechanism 32 and motor 34. Quick release mechanism 38, one embodiment shown in exploded view in FIG. 14, generally includes pivot 44. Pivot 44 may be a threaded rod with a knob 46 at one end. As shown, bracket 48 may be a part of the guidance mechanism 32 (which may also be the rotational pivot for the guidance mechanism discussed above). Pivot 44 may be engaged with moveable end 26 via the bracket 48, is inserted into bracket 48, and is held in place by threading pivot 44 into vertical plate 35. Removal of pivot 44 from plate 35 allows the guidance mechanism 32 and motor 34 to be disengaged from motor system 20 for easy launch and removal of the watercraft from the water.
Skeg 60, see FIG. 1, is affixed at the bottom side of the motor. Skeg 60 a device that is intended to take a striking force between the motor system and a submerged obstruction.
A source of electricity 36 may be provided. Electricity source 36 may be any marine battery. The electrical source may be operatively connected to the winch and/or motor by any conventional means. As shown, FIG. 14, cord 50 interconnects the electrical source 36 to the motor 34, the cord 50 may run through opening 52 of the hull. The electrical may be located anywhere within or on the watercraft 10. Source 36 may be located aft of the cockpit 16 (i.e., the stern) within the watercraft (i.e. below a hatch). The source 36, however, may be located in the bow or between the bow and the stern, or in a battery box located behind the cockpit on the top of the hull.
In operation, see FIGS. 6-8, the winch may be used to raise and lower the motor system between an up position (FIG. 6), a down position (FIG. 8) and a mid position (FIG. 7). In FIGS. 9-13, the operation of the guidance mechanism 32 is illustrated as controlled by the steering mechanism. In FIG. 14, the operation of the quick release mechanism 38 is illustrated.
The motor system 20 may be made of any material, but in one embodiment the structural parts, (e.g., plate and brackets),may be made of light-weight and/or non-corroding materials, such as aluminum, plastic, and/or fiber reinforced composite, and combinations thereof.
The present invention may be embodied in other forms without departing from the spirit and the essential attributes thereof, and, accordingly, reference should be made to the appended claims, rather than to the foregoing specification, as indicating the scope of the invention.
