The present invention relates to small boats and more particularly to outrigger stabilizers for a kayak or canoe.
Canoes and the covered version known as kayaks have been known for hundreds of years. The first canoes were made from wood and animal skins Kayaks were great for hunting in cold arctic waters. They were highly maneuverable and allowed their users to catch seals and walruses. Eventually, seal bladders were added to make them nearly unsinkable and hunting expeditions could last much longer if the kayak were fully provisioned.
Unfortunately, the very maneuverability of the kayak was also a weakness due to its instability. In the related art, it is well known that canoes or kayaks and other small watercraft are easily upset by sudden movement of an occupant or rough water in which waves hit against the boat side and can potentially tilt it over in an upsetting fashion. To counter the instability, it is known to attach outriggers as was common in Hawaii. While this improves stability, it greatly reduces the maneuverability so highly prized among kayak operators.
There is a need for a kayak type boat that maintains maneuverability yet is stable. Additionally, it is known that it requires many hours of practice to become an experienced boatman in a canoe or kayak.
Examples of related art similar to the present invention are described below, and the supported teachings of each reference are incorporated by reference herein:

At least one clamp secures the frame to a watercraft. The clamp comprises clamp members that are securable together such that the frame and a portion of the watercraft are held together between the clamp members.
U.S. Patent Application No. 2006/0102063: ACCESSORY PLATFORM ASSEMBLY FOR A KAYAK, published May 18, 2006 to BOELRYK, discloses an accessory platform assembly for attachment to kayak. The assembly comprises attachment means for attaching the assembly to the deck of a kayak, a frame attached to the attachment means, the frame holding a platform and allowing the platform to be moved from a closed position to an open position whereby in the open position the deck of the kayak lying below the platform in the closed position is exposed. The assembly optionally includes an outrigger assembly comprising parallel arms attached at one end to the attachment means and having an outrigger floatation device attached to an opposite end of the arms spaced away from the kayak to provide increased stability to the kayak.
The inventions heretofore known suffer from a number of disadvantages.

Referring now to the
Starting, in one embodiment, with the stabilizers 110 in a folded or stored position located on top of the kayak, a user may rotates the stabilizers 110 outward so
that the stabilizer 110 is positioned over the edge of the kayak 105. Next, the sliding support arm 115 may be moved back towards the kayak 105. In this configuration, as the stabilizer 110 is pushed upward by water pressure, sliding support arm 115 prevents it from rotating, thus stabilizing the kayak I 05.
To retract the stabilizers 110, in one embodiment, the process is reversed. The sliding support arms 115 are moved outward and then the stabilizers 110 are rotated to a retracted position. The length of the sliding support arm 115 may be varied to match a selected kayak or canoe. Additionally, a tie down such as hook and loop tie-down may be used (not shown) to secure the stabilizer 110 from moving while transporting the kayak 105.
Referring now to
Optionally, it is possible to place one stabilizing unit in the front of a kayak (not shown) instead of in the rear as shown. Another option not shown is a single rotating support rod that connects the rear and front stabilizers so an appropriately equipped one person kayak may have a front and rear stabilizer that is operable by one person.
The stabilizer may be made of most any known material, like plastic, carbon fiber of other appropriate material. The frame may also be constructed of most any known material, like aluminum or other appropriate material such as PVC pipe.
Although the present invention has been described in relation to particular embodiments thereof, many other variations and modifications and other uses will become apparent to those skilled in the art.
In another embodiment of the invention, starting with the stabilizers 110 in a folded or top position, a user rotates the stabilizers 110 outward so that the stabilizer 110 is positioned over the edge of the kayak 105. Next, the stabilizers are locked into their extended support position over the edge of the kayak 105, as detailed in the

A series of extension adjustment holes 208 are located on the end of the stabilizer support arm 215. In this embodiment of the invention, a detent style fastener is fixedly attached to the end of the arm base 214. The relative position of the stabilizer support arm 215 and the arm base 214 becomes locked when the detent fastener 210 synchronizes with an extension adjustment hole 208. The distance 216 can be adjusted by depressing the detent fastener 210 and sliding 212 the stabilizer support arm 215 to a new position and allowing the detent fastener to synchronize and lock with another extension adjustment hole 208. In this embodiment a detent fastener is used to lock the stabilizer support arm 215 and the arm base 214; however, it is anticipated that any number of fastening devices or suitable locking means, including but not limited to bolts, rivets, pins, screws, collets, clamps and clips, could be used to securely lock the stabilizer support arm to the arm base.
The arm base 214 is rigidly attached to the rotating support 117, such that a change in the height of the stabilizer creates an angular movement of the arm base 214, which in turn rotates the rotating support 117.
Also illustrated in
The stabilizer position locking mechanism is provided by a locking frame member 131. The locking frame member 131 may be tubular in construction, and would be rigidly attached to the kayak 105 using, for example, bolts or other suitable devices for securing it to the kayak 105. The distal end of the locking frame member 131, which sleeves and supports the rotating support 117 may have a series of frame positioning holes 197, 198 and 202. Corresponding positioning holes 196, 199, 203 are located in the rotating support 117.
If the stabilizer 110 is lowered, which in turn rotates the rotating support 117, it brings the frame positioning hole 198 in alignment with the matching positioning hole 199. In this arrangement, the stabilizer 110 is in the lower than horizontal position, as illustrated in
If the stabilizer 110, on the other hand, is lowered to an alternative arrangement, shown in
In this embodiment of the invention, the locking mechanism is illustrated as a bolt 204, which is placed in the two matching holes. In
The float rotating system 300 comprises a rotatable handle 320 operatively coupled to a rotating support 117. The handle 320 is linearly moveable between an engaged position and disengaged position and the rotating support 117 is operatively coupled to the frame system 400 and moveable between a locked and unlocked position. The handle 320 operatively coupled to the rotating support 117 may be accomplished by the handle 320 releasably engaging the rotating support 117 through linear movement of the rotatable handle 320 along the rotating support 117. Rotation of the handle 320 when engaged with the rotating support 117 rotates the rotating support 117. The float 110 is moved between the stored position and the deployed position in response to rotating the handle 320 of the float rotating system 300.
The handle 320 in the disengaged position allows for free rotation of the handle 320 about the rotating support 117. The float rotating system 300 comprises a first spring 312, wherein the first spring 312 biases the handle 320 toward the engaged position with respect to the rotating support 117.
The rotating support 117 is moveable between the locked position and the unlocked position in response to moving a lock pin corresponding to a plurality of apertures 318 extending through a depth plate 316 of the float rotating system 300 between a locked position and unlocked position. The locked position is the lock pin extending into one aperture 318 of the plurality of apertures 318 and the unlocked position is not extending into any of the plurality of apertures 318.
The float rotating system 300 comprises a second spring 314, wherein the second spring 314 biases the lock pin toward a locked position. The lock pin is moved to the unlocked position in response to movement of the handle 320 in a first linear direction. The lock pin is moved to the locked position in response to movement of the handle 320 moving to a default position.
Referring further to
The float rotating system 300 comprises a rotatable handle 320 operatively coupled to a rotating support 117. The handle 320 is operatively coupled to the rotating support 117 by being fixedly coupled to the rotating support 117 such that rotation of the handle results rotation of the rotating support 117. The float 110 is moved between the stored position and the deployed position in response to rotating the handle 320 of the float rotating system 300. This is accomplished at least because of the coupling of the stabilizer arm 310 to the rotating support 117, such that rotation of the rotating support 117 results in rotation of the float 110 about an axis of the rotating support 110. In other words, the axis of the rotating support 117 is the axis of rotation about which the float 110 rotates. In at least this way, the float 110 is moved between the stored position and the deployed position. Further, in at least this way, the float 110 is moved between the stored position and the deployed position in response to rotation of the handle 320.
Referring to
The float rotating system 300 comprises a lock spring 315, wherein the lock spring 315 biases the float rotating system 300 toward a locked position wherein the float 110 is not locked from rotation about the rotating support 117. This may be accomplished by biasing the lock pin 330 toward a locked position. The lock pin 330 may be located on the stabilizer arm 310 adjacent the depth plate 316 and is moved to the unlocked position in response to movement of the handle 320 from a default linear position in a first linear direction. Movement of the handle 320 in the first linear direction moves the rotating support 117 and the stabilizer arm 310 in the first linear direction, and thereby moves the lock pin 330 out of one of the apertures 318 and into the unlocked position, allowing the handle 320, the rotating support 117 and the stabilizer arm to rotate in order to rotate the float 110. The lock pin 330 is moved to the locked position in response to movement of the handle 320 moving to the default linear position, wherein the lock pin 330 engages an aperture 318 of the depth plate 316.
The depth plate 316 may include a plurality of apertures 318. In one embodiment shown in
Because lock spring 315 biases the lock pin 330 into the locked position with the lock pin 330 inserted within one of the apertures 318a, 318b, 318c, 318d, and 318e, aligning the lock pin 330 with an aperture and releasing the handle 320 will move the handle 320 into the default linear position and the lock pin 330 into the locked position.
In another example, after moving the lock pin 330 into the unlocked position from aperture 318a with the float 110 in the stored position and rotating the handle 320 until the lock pin 330 does not align with an aperture 118a, a user may then allow the handle 320 to move toward the depth plate 316 by reducing the force applied to the handle in the first linear direction, wherein the lock pin 330 engages a surface of the depth plate. The user may then release all force in the first linear direction and rotate the handle 320 toward aperture 318b. As the lock pin 330 is rotated to aperture 318b, the lock pin 330 will eventually align with aperture 318b and the lock spring 315 will force the lock pin 330 into the aperture 318b, thereby locking the float at that particular depth. This may be repeated for each aperture 318a, 318b, 318c, 318d, and 318e of the plurality of apertures 318. While the depth plate 316 is shown with five apertures extending there through, it is understood that any number of apertures may be included.
Accordingly, the components defining any retractable stabilizer for a watercraft may be formed of any of many different types of materials or combinations thereof that can readily be formed into shaped objects provided that the components selected are consistent with the intended operation of a retractable stabilizer for a watercraft. For example, the components may be formed of: rubbers (synthetic and/or natural) and/or other like materials; glasses (such as fiberglass) carbon-fiber, aramid-fiber, any combination thereof, and/or other like materials; polymers such as thermoplastics (such as ABS, Fluoropolymers, Polyacetal, Polyamide; Polycarbonate, Polyethylene, Polysulfone, and/or the like), thermosets (such as Epoxy, Phenolic Resin, Polyimide, Polyurethane, Silicone, and/or the like), any combination thereof, and/or other like materials; composites and/or other like materials; metals, such as zinc, magnesium, titanium, copper, iron, steel, carbon steel, alloy steel, tool steel, stainless steel, aluminum, any combination thereof, and/or other like materials; alloys, such as aluminum alloy, titanium alloy, magnesium alloy, copper alloy, any combination thereof, and/or other like materials; any other suitable material; and/or any combination thereof.
Furthermore, the components defining any retractable stabilizer for a watercraft may be purchased pre-manufactured or manufactured separately and then assembled together. However, any or all of the components may be manufactured simultaneously and integrally joined with one another. Manufacture of these components separately or simultaneously may involve extrusion, pultrusion, vacuum forming, injection molding, blow molding, resin transfer molding, casting, forging, cold rolling, milling, drilling, reaming, turning, grinding, stamping, cutting, bending, welding, soldering, hardening, riveting, punching, plating, and/or the like. If any of the components are manufactured separately, they may then be coupled with one another in any manner, such as with adhesive, a weld, a fastener (e.g. a bolt, a nut, a screw, a nail, a rivet, a pin, and/or the like), wiring, any combination thereof, and/or the like for example, depending on, among other considerations, the particular material forming the components. Other possible steps might include sand blasting, polishing, powder coating, zinc plating, anodizing, hard anodizing, and/or painting the components for example.
In one embodiment, the purpose of the stabilizer assembly is threefold: (1) Provide a stabilizer assembly that can be easily installed/removed on a kayak, canoe or watercraft; (2) Provide adjustable levels of stabilization for a kayak, canoe or other type of watercraft, where the degree of stabilization can be adjusted for the situation and condition of the water; (3) Provide a training help or aid for an operator, learning to maneuver a kayak. This invention would assist the operator much like training wheels help a child learn how to ride a bike.
In another embodiment, when the vessel is being transported, the stabilizers would most likely be rotated to the top position as shown in
As the operator becomes more familiar with the craft and more adept at operating it in turbulent waters, the stabilizers could be retracted and elevated, as shown in
As the skill of the operator becomes greater, the stabilizers can be further retracted and elevated, such as a maximum essentially horizontal position, which is illustrated in
Once the operator become adept in all phases of the craft, the stabilizer assembly could be easily removed, much like removing training wheels from a bike.
There are many advantages that are realized by the retractable stabilizer system of the illustrated embodiments of the invention that are not taught by the known prior art. One skilled in the art will realize the benefits that are afforded the novice or beginning kayaker, or for fisherman that wants to stand in the kayak while fishing.
Another embodiment of the present invention includes a method of using a retractable stabilizer, the method comprises aligning a handle of a float rotating system with a stabilizer arm with a float of the retractable stabilizer in a stored position; moving the handle into an engaged position; rotating a float to a deployed position in response to rotating the handle in the engage position; moving the handle into the default position when the float is in the desired orientation; moving the handle into a disengaged position; and rotating the handle while in the disengaged position to rotate the handle to a stored position without rotating the float.
The method may include moving the handle into the engaged position automatically moves a lock pin of the float rotating system from a locked position to an unlocked position. Moving the handle from the engaged position to the default position automatically moves the lock pin from the unlocked position to the locked position. Moving the lock pin between the locked position and unlocked position includes moving the lock pin between engagement and disengagement with any of the plurality of apertures of a depth plate of a frame system of the retractable stabilizer.
The method further comprises moving the handle into the disengaged position; and rotate the handle until it is aligned with the stabilizer arm when the float is in the deployed position. Additionally, the method includes moving the handle into the engaged position; and rotating the float into the stored position in response to rotating the handle. Further still, the method includes moving the handle into the disengaged position; and rotate the handle while in the disengaged position to rotate the handle to a stored position without rotating the float.
Embodiments of the present invention may include another method of using a retractable stabilizer. The method comprises moving the float rotating system into an unlocked position from a locked position; rotating a float to a deployed position from a stored position in response to rotating the handle; and moving the float rotating system into the locked position from the unlocked position.
The step of moving the float rotating system into the unlocked position from the locked position may comprise moving a lock pin of the float rotating system from a locked position to an unlocked position. Further, the step of moving the float rotating system into the locked position from the unlocked position may comprise moving the lock pin from the unlocked position to the locked position.
In the method, moving the lock pin between the locked position and unlocked position includes moving the lock pin between engagement and disengagement with any of the plurality of apertures of a depth plate of float rotating system.
The method may further comprise adjusting the depth a float of the retractable stabilizer extends within a body of water travelled by a watercraft the retractable stabilizer is coupled to in response to engaging the lock pin within a different aperture of the plurality of apertures of the depth plate.
The method may also comprise moving the float rotating system into the unlocked position from the locked position; rotating a float to the stored position from the deployed position in response to rotating the handle; and moving the float rotating system into the locked position from the unlocked position.
It is understood that the above-described embodiments are only illustrative of the application of the principles of the present invention. The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiment is to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
For example, although the reference has been made to kayaks throughout the specification, one skilled in the art will realize after reading the specification in light of the illustrated embodiment, there are other uses for the illustrated embodiments of the invention. Specifically, the same device would be adaptable to other vessels, like canoes, row boats, wave runners, ski boats, fishing boats, etc.
It is further noted that the structural elements of the illustrated embodiments may be made of most any material. For example, the material of the frame may be made of aluminum, fiber glass, plastics, ceramics, wood, etc. Additionally, the material for the stabilizers may be made hollow or solid, made of foam, wood, aluminum, plastic, fiber glass, etc.
Although the frame of the illustrated embodiment is illustrated to have a certain number of parts and shapes, any number of parts and shapes is considered to be within the scope of the presently illustrated embodiments. For example, sheets of material could be used instead of tubes. Any number of tubes could be used for increased supports.
Moreover, although the floats are illustrated to store above the surface level of the kayak, one skilled in the art could easily modify the illustrated embodiment. For example, the floats could be positioned below the top surface of the kayak by having recessed cavities built within the top of the kayak.
Another modification to the illustrated embodiment includes forming the entire structure integral with the kayak. For example, key features of the frame could be molded into the kayak. Wherein, the parts located on top of the. kayak could be molded into the walls or be internally portioned inside the kayak. The tubes or sheets of material could also be more conformal to the kayak or boat.
Thus, while the present invention has been fully described above with particularity and detail in connection with what is presently deemed to be the most practical and preferred embodiment of the invention, it will be apparent to those of ordinary skill in the art that numerous modifications, including, but not limited to, variations in size, materials, shape, form, function and manner of operation, assembly and use may be made, without departing from the principles and concepts of the invention as set forth in the claims. Further, it is contemplated that an embodiment may be limited to consist of or to consist essentially of one or more of the features, functions, structures, methods described herein.
