Description
BACKGROUND OF THE INVENTION
Field of the Invention

The present invention relates to motor mounts, and, in particular, to a motor mount for storing a trolling motor assembly below a surface of, for example, a deck.


Description of the Related Art

The pleasure boat industry has exploded in recent years, and to meet the needs of fishing boats, for example, trolling motors have become popular. A trolling motor is usually a secondary source of propulsion for a vessel. Trolling motors allow for a relatively small amount of thrust to propel a boat or other vessel through the water slowly and quietly. Typically, trolling motors are electric powered, using the vessel's existing power source or stand-alone power source (e.g., a separate battery). Such trolling motors are typically mounted to the top surface of the vessel's deck, and are configured to allow for storage of the trolling motor on top of the surface when not in use. Early designs allowed for manual manipulation of the trolling motor assembly to place it in the stowed position. For example, the trolling motor assembly might comprise a motor base and a propulsion shaft, where the propulsion shaft includes a propeller, and an optional head unit. In operation, the propulsion shaft is perpendicular to the motor base and extended downward into the water. Stowing the trolling motor includes lifting the propulsion shaft upward out of the water, and rotating the shaft to a horizontal and parallel position to the deck.


Recently, trolling motors have been designed that allow for such manipulation of the trolling motor assembly to transition between a deployed/extended position in operation to the stowed position, and vice-versa, automatically or with mechanical assistance. For example, U.S. Pat. No. 9,296,455 entitled “Trolling Motor” to Bernloehr et al., filed Apr. 17, 2014, describes such a trolling motor that provides mechanically assisted or automated stow/deploy and trim adjustment mechanisms. The trolling motor includes a motor base assembly with a steering module mounted to the base assembly. The steering module includes an internal drive arrangement for providing an output torque. The steering module also includes a trim module rotatably mounted to an upper portion of the steering module. A motor shaft assembly including a motor shaft, a head unit attached to an upper end of the motor shaft, and a motor power unit attached to a lower end of the motor shaft is also provided. The motor shaft extends through the base assembly, steering module, and trim module. A torque transfer arrangement is mounted between the trim module and the motor shaft of the motor shaft assembly for transferring the output torque provided by the steering module to the motor shaft to rotate the motor shaft assembly about a rotational steering axis. Such a trolling motor advantageously provides a user with a contemporary trolling motor at a lower cost of purchase, operation, and maintenance given a more compact and efficient design.


The recreational boat industry includes other types of pleasure craft, such as “lake boats” for similar applications. One type of such pleasure craft is a pontoon boat, which is a low-deck height (or “flattish”) boat that relies on pontoons to float. Common pontoon boat designs include lake boats, fishing boats, catamarans, and the like with a deck positioned over two (or more) pontoons. Pontoons may be simply constructed from sealed cylinders such as pipes or barrels, or fabricated as boxes from metal or concrete. Pontoon boat drafts may be as shallow as eight inches, which reduces risk of running aground and underwater damage, and are ideal for lake use. Pontoon boats for pleasure boating and fishing can be low cost for their capacity, and sales of such watercraft have exploded in recent years.


Trolling motors might be employed with pontoon boats, but their use is generally awkward. In a small fishing vessel, the trolling motor is typically fixed to the top deck at the bow, but in pontoon boat deck space and access to the foredeck (bow) is limited. Consequently, trolling motors are seldom used with, or installed in, pontoon boats.


SUMMARY OF THE INVENTION

This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.


In one embodiment, the present invention is a motor mount to deploy a boat motor comprising a track with guide rails extending along each side of the track to form a channel, and a sled positioned within the channel. The track includes a first end block between the guide rails at a first end, a second end block between the guide rails at a second end, and a rod rotatably fixed between the first and second end blocks, wherein the first end block has a rack formed thereon opposite to a top surface of the track, and the guide rails form an opening adjacent to the first end block, between the first and second end blocks, and opposite to the track top surface. The sled includes a top plate and a bottom plate, the top plate and the bottom plate having corresponding ends fixed with a hinge, the top plate fastened about the rod, the bottom plate have a gear formed around the hinge, and the hinge positioned facing toward the first end block. Rotating the rod in a first direction through the top plate moves the hinge of the sled within the channel toward the first end block, and rotating the rod in a second direction moves the sled within the channel toward the second end block and, when the rod rotates in the first direction and reaches the first block, the gear of the bottom plate engages the rack of the first end block, the bottom plate rotates about the hinge through the opening, and extends inverted over the first end block to an extended position.

DETAILED DESCRIPTION

In accordance with described embodiments, a motor mount for use with, for example, a trolling motor, allows for automatic or otherwise mechanical deployment of the trolling motor when in operation and stowing of the trolling motor under a deck when not in use. Such motor mount as described herein might advantageously be used with, or installed in, pontoon boats. When employed for such pontoon boat applications, the trolling motor might be stored under the pontoon boat deck and between the pontoons. Embodiments of the motor mount described herein might be powered using the existing power source or stand-alone power source (e.g., a separate battery) of the pontoon boat. Preferred embodiments of the motor mount might be advantageously employed in conjunction with the type of trolling motor described in, for example, U.S. Pat. No. 9,296,455 entitled “Trolling Motor” to Bernloehr et al., filed Apr. 17, 2014, the teachings of which are incorporated in their entirety herein by reference.


Before describing an exemplary embodiment of the trolling motor mount, use of the trolling motor mount, its general configuration and advantages is described with respect to FIGS. 1A, 1B and 1C. FIG. 1A shows a side view of pontoon boat 10 employing an exemplary embodiment of the present invention in a stowed position. FIG. 1B shows a front (bow) view of pontoon boat 10 employing the exemplary embodiment of the present invention in a stowed position. In accordance with exemplary embodiment, pontoon boat 10 having a deck 2 includes the exemplary embodiment of trolling motor mount 3 fastened under deck 2. Trolling motor assembly 4 includes a motor base 5 and propulsion shaft 6. In a stowed position, trolling motor 10 includes propulsion shaft 6 rotated to a horizontal (also with respect to motor base 5) and parallel position to deck 2. Trolling motor assembly 4 in a stowed configuration is mounted to a bottom surface of trolling motor mount 3, under deck 2, and between pontoons 1a and 1b, allowing for storing the motor when not in use in a protected position underneath deck 2.



FIG. 1C shows a side view of a pontoon boat employing an exemplary embodiment of the present invention in a deployed position. Motor mount 3 is now extended beyond front 9 of pontoon boat 10, inverting motor base 5. In operation, propulsion shaft 6 is perpendicular to motor base 5 and extended downward into the water. Such trolling motor mount advantageously provides a user with a contemporary trolling motor given a more compact and efficient design that can be employed easily in pontoon boats.


An exemplary embodiment of a trolling motor mount in accordance with the present invention is now described. FIG. 2 shows diagram of an exemplary embodiment of the trolling motor mount viewed from the side in a stowed position, and FIG. 3 shows diagram of an exemplary embodiment of the trolling motor mount viewed from the bottom in the stowed position.


Referring to FIGS. 2 and 3, trolling motor mount 3 includes track 20, sled 30, threaded rod 28 (e.g., a worm or screw), first end block 25, and second end block 27. First end block 25 is positioned at one end of the channel of track 20 generally near, for example, the front of a vessel, and second end block 27 is positioned at the opposite end of the channel of track 20. Track 20 provides a housing for sled 30 and includes top surface 21, and side guide rails 22 that form a generally u-shaped channel for sled 30 to slide in. Top surface 21 of track 20 might be fastened underneath a deck of a pontoon boat, and a trolling motor assembly (not shown in FIGS. 2 and 3) is mounted on a bottom motor area 36 of bottom plate 32 of sled 30.


Threaded rod 28 is generally fixed between first end block 25 and second end block 27 by points 39 and 40, respectively, in a manner that permits rotation of threaded rod 28. One end of threaded rod 28 extends through second end block 27, and might be fastened to either a motor or mechanical crank (not shown in FIGS. 2 and 3) to enable rotation of threaded rod 28.


Sled 30 includes top plate 31 and bottom plate 32, which are fastened together at corresponding ends by hinge 33. Hinge 33 is generally positioned to face toward first end block 25. Threaded rod 28 passes through a corresponding threaded receptacle (e.g., one or more nuts) in top plate 31 so that when threaded rod 28 is rotated, sled 30 slides within the channel of track 20. Bottom plate 32 includes gear 34 formed about hinge 33, and first end block 25 includes a (gear) rack 26 formed on its bottom surface.


Track 20 further includes an open area 50 within the bottom of the channel, and a closed are 51. When sled 30 is within closed area 51, the edges of bottom plate 32 slide on, and are retained by, guide rails 22. When sled 30 is within open area 50, the edges of bottom plate 32 are no longer retained by guide rails 22, permitting bottom plate 32 to rotate about hinge 33 out of open area 50. When top plate 31 rides on threaded rod 28 in either open area 50 or closed area 51, top plate 31 is retained within the channel by threaded rod 28 and guide rails 22.



FIG. 4A shows a cross section of track 20 showing the channel in open region 50, allowing bottom plate 32 of sled 30 to pass through open region 50. As shown, track 20 might include reinforced area 60 at bottom of guide rail 22, to provide some rigidity to an aluminum extrusion employed for track 20. FIG. 4B shows a cross section of track 20 showing the channel in closed (guided) region 51, allowing sled 30 to pass through closed region 51. As shown, track 20 might include reinforced area extended area 61 at bottom of guide rail 22, to allow sled 30 to sit within guide rails 22 on extended area 61 closed region 51 while being firmly retained within the channel.


Returning to FIGS. 2 and 3, rotating threaded rod 28 in a first direction through top plate 31 moves hinge 33 of sled 30 within the channel toward first end block 25, and rotating threaded rod 28 in a second direction moves sled 30 within the channel toward second end block 27. When threaded rod 28 rotates in the first direction and reaches first end block 25, gear 34 of bottom plate 32 engages rack 26 of first end block 25, bottom plate 32 rotates about hinge 33 to flip bottom plate 32 through the open area 50, and extends bottom plate 32 inverted over first end block 25 to an extended, or deployed, position. Blocks 29a and 29b are mounted about rack 26, and slots 38a and 38b are formed either side of or within gear 34. Blocks 29a and 29b may engage slots 38a and 38b, respectively, to allow for alignment and rigidity of extended bottom plate 32 in the deployed position. When a trolling motor assembly (not shown in FIGS. 2 and 3) is mounted on a bottom motor area 36 of bottom plate 32 of sled 30, this rotation about hinge 33 to flip bottom plate 32 through the open area 50 also flips the trolling motor assembly over to be positioned, for example, on the deck surface of a pontoon boat. Recess 41 shown at a rear of bottom plate 32 might allow space for a propulsion shaft of the trolling motor assembly to move up and down.


From a deployed position, rotating threaded rod 28 in a second direction moves sled 30 within the channel toward second end block 27, reversing the deployment operation. Bottom plate 32 rotates about hinge 33 to reverse-flip and return bottom plate 32 through open area 50, to retract bottom plate 32 into the channel of track 20 to a stowed position. As bottom plate 32 enters open area 50 and slides toward second end block 27, inclined areas 35a and 35b engage areas 61 (shown in FIG. 4B) of guide rails 22 to help lift bottom plate 32 of sled 30 into the closed area 51 of the channel of track 20.


In order to provide the operation of inverting bottom plate 32, top plate 31 and bottom plate 32 are preferably configured as shown in FIGS. 5, 6 and 7. In operation, sled 30 passes over first end block 25, and top plate 31 passes over first end block 25 to engage gear 34 with rack 26. Bottom plate 32 is generally positioned within a recess in top plate 31, as shown and described below with respect to FIG. 5.



FIG. 5 shows sled 30 having top plate 31, bottom plate 32 with gear 34, and hinge 33 as it passes over first end block 25 during a transition between deployed and stowed positions. Nut 39 engages threaded rod 28 within a cavity of top plate 31, and sled 30 might be stopped at the end of first end block 25 by bumpers 200a and 200b, having cushions 201a and 201b, respectively. As shown, top plate 31 includes a recess 202 in which bottom plate 32 is positioned, with walls 203a and 203b extending to form recess 202 and provide support of hinge 33. As top plate 31 passes over first end block 25, it passes over rack 26, and opening 205 allows for gear 34 to make contact with rack 26. Continued movement of top plate 31 provides force for rotation about hinge 33. Blocks 29a and 29b may engage slots 38a and 38b, respectively, to allow for alignment and rigidity of extended bottom plate 32 in the deployed position. A trolling motor assembly (not shown in FIG. 5) is mounted on a bottom motor area 36 of bottom plate 32 of sled 30.



FIG. 6 shows a relation of the first end block and the top and bottom plates of the sled in a stowed position. FIG. 7 shows a relation of the first end block and the top and bottom plates of the sled in a half-deployed position when rotated 90 degrees by engagement of gear 34 with rack 26.



FIG. 8 shows a motor and motor control system 1000 as might be employed by exemplary embodiments of the present invention. As described above, rotation of threaded rod (e.g., screw) 28 moves sled 30 within the channel of track 20, thereby stowing or deploying trolling motor 4. Also, as described above, rotation of threaded rod 28 might be accomplished by an electric motor. Referring to FIG. 8, motor box 1010 includes electric motor 1011 to drive threaded rod 28, and operation of electric motor 1011 is enabled by motor control 1012. Given an input, which might, for example, be from remote device 1013 coupled to motor box 1010, motor 1011 rotates threaded rod 28 to stow or deploy trolling motor 4. Remote device 1013 might be implemented either directly or wirelessly coupled to motor box 1010. Motor control 1012 might be coupled to motor base 5 of trolling motor assembly 4, and might receive or provide control signals to trolling motor assembly 4 to rotate, flip and/or extend propulsion shaft 6 as the trolling motor assembly's configuration is changed to stow or deploy trolling motor 4. Motor mount 3 might further include sensors 1001a-1001d to monitor position of sled 30 within track 20 during operation, and sensors 1001a-1001d might provide position information signals to motor control 1010. Motor control 1012 might be implemented with simple circuitry, or might include a processor and associated circuitry to implement algorithms to more precisely control operation of motor and motor control system 1000. Such control in various embodiments might include speed of motor and sled, movements of the deployment or stowage of the trolling motor assembly during configuration changes, as well as safety precautions when jams or other non-desirable events occur during operation.
