KAYAK-STABILITY SYSTEM
A kayak stability system that stabilizes a kayak and supports a kayaker in water such that he or she can more conveniently enter or re-enter the kayak from the water. The device includes at least one sponson attached to the kayak and retractably moveable from a stored position along an exterior surface of a hull of the kayak to a deployed position over the water to provide added buoyancy to the kayak for stabilizing the kayak and a stability arm for supporting the kayaker in the water. At least one stabilizing arm is also pivotally attached to the kayak and retractably moveable from a stored position along a surface of the hull to a deployed position over the water in spaced relation to a corresponding sponson. A combination of the deployed sponson and stabilizing arm provides support to a kayaker to allow the kayaker to more conveniently enter or re-enter the kayak from the water.
1. Field of the Invention
The present invention relates, generally, to a kayak and, more particularly, to a system for stabilizing the kayak and supporting a kayaker in water such that he or she can more conveniently enter or re-enter the kayak from the water.
2. Description of Related Art
It is known in canoeing and, in particular, kayaking for a kayak moving in a body of water to tip, flip, capsize, or otherwise overturn. This, in turn, causes a corresponding kayaker to be dumped from a cockpit of the kayak into the water either via a “wet exit”—wherein the kayaker intentionally extracts himself or herself from the cockpit while he or she is submerged under the surface of the water—or otherwise. This is especially true in dangerous kayaking conditions, such as when it is extremely windy and, thus, the waters are perilously wavy. When the kayak overturns, the cockpit can become flooded. Upon being dumped, the kayaker must then rescue himself or herself by resurfacing above the water, swimming to the kayak, possibly pumping out enough water from the cockpit to allow him or her to sufficiently tip the kayak, tipping the kayak, and re-entering the cockpit. After the kayaker has re-entered the cockpit, he or she may also finish pumping out any remaining water therein, such that he or she can resume kayaking or return safely to shore.
However, it is generally more difficult for kayakers who are beginners, relatively weak or unfit, and/or disabled or physically challenged to support themselves above the water surface, return to the kayak, pump out water from the cockpit, and/or re-enter the cockpit from the water. As a result, it is known for a kayak to include at least one rigid, floatable device to stabilize the kayak in the water and assist such a kayaker to support himself or herself above the water surface such that he or she can, for instance, pump out water from the cockpit. These devices include outriggers, sponsons, and the like.
For example, such a device, like an outrigger, can be attached to a hull of the kayak above the waterline. Generally, an outrigger device includes a shaft with one end that is permanently or semi-permanently attached to the hull and a float disposed on the free end of the shaft. The device extends to and floats on the water to more stabilize the kayak and, thereby, lessen the possibility of the kayak overturning in the first place. The device also creates a stability arm onto which the kayaker, who has been dumped into the water, can hold to assist him or her pump out water from the cockpit or use to draw him or her back to the cockpit.
One problem with such a device is that the kayak must be used while the device is permanently deployed onto the water. Of course, this deployment seriously inhibits, if not prohibits, the experience of kayaking by limiting operative speed and range of motion of the kayak. Another problem with the device is that to remove it from the water, the device must be disassembled from the kayak and either stored distant the kayak or stowed within the hull, where valuable storage compartments may already be stored with personal items, first-aid devices, and/or other kayaking implements. In turn, to deploy the device onto the water, the device must be retrieved from either distant the kayak or the hull and assembled to the kayak. This disassembly, storage or stowage, retrieval, and assembly, especially if performed continually, can be rather inconvenient, labor-intensive, and time-consuming.
In view of the above, the devices of the related art do not adequately assist beginner, relatively weak or unfit, and/or disabled or physically challenged kayakers. More specifically, the use of the devices of the related art does not adequately assist such a kayaker to conveniently enter or re-enter the cockpit from the water. In particular, the kayaker, especially one who is physically challenged, must use a great amount of his or her leg or trunk strength to get into the cockpit from the step or sling. Also, the use of the devices of the related art seriously inhibits, if not prohibits, the kayaking experience. Furthermore, the devices of the related art can be inconvenient, labor-intensive, and time-consuming to use.
Accordingly, it can be seen that needs exist for a system that adequately assists beginner, relatively weak or unfit, and/or disabled or physically challenged kayakers to conveniently enter or re-enter the kayak cockpit from the water. In particular, a need exists for such a system that does not require the kayaker, especially one who is physically challenged, to use a great amount of his or her leg or trunk strength to get into the cockpit from the water. A need also exists for such a system that is relatively more convenient and less labor-intensive and time-consuming to use. Additionally, a need exists for such a system that can be easily and quickly deployed onto the water, retracted from the water, and stowed on the kayak such that the system can be easily deployed and retracted.
SUMMARY OF THE INVENTIONThe present invention overcomes the problems in the related art in a system that stabilizes a kayak and supports a kayaker in water such that he or she can more conveniently enter or re-enter the kayak from the water. The system includes at least one sponson attached to the kayak and retractably moveable from a stored position along a surface of a hull of the kayak to a deployed position over the water to provide added buoyancy to the kayak for stabilizing the kayak and to assist re-entry to the kayak or canoe. At least one stabilizing arm is attached to the kayak and retractably moveable from a stored position along the interior/exterior surface of the hull to a deployed position over the water in spaced relation to a corresponding sponson. A combination of the deployed sponson and stabilizing arm provides support to an upper body of the kayaker to allow the kayaker to more conveniently enter or re-enter the kayak from the water.

Referring now to
To this end, example embodiments of the stability system 20 generally include at least one sponson 22 and at least one stabilizing arm 24 attached to the kayak 10. The sponsons 22 are retractably moveable from a stored position along a surface of the hull 12 to a deployed position over the water to provide added stabilization for the kayak 10. Similarly, the stabilizing arm 24 is retractably moveable from a stored configuration along a surface of the hull 12 to a deployed configuration over the water in spaced relation to a corresponding sponson 22. A combination of at least one sponson 22 and at least one stabilizing arm 24 provides support to a kayaker in the water to allow the kayaker to more conveniently enter or re-enter the kayak 10 therefrom. It should be noted that in example embodiments, the at least one sponson 22 and at least one stabilizing arm 24 are maintained along the exterior of the kayak 10 in a stored configuration, however, in alternative embodiments the at least one sponson 22 and at least one stabilizing arm 24 are stored within the hull 12 of the kayak so the at least one sponson and the at least one stabilizing arm do not interfere with a kayaker' s ability to paddle.
In a preferred example embodiment of the stability system 20, as depicted in
When in the stored configuration, as shown in
In this way, the kayaker, being located in either the water or cockpit 14, can immediately and readily manually pivot and, thereby, deploy one or both of the sponsons 22 from a stored configuration to a deployed configuration, wherein the sponsons 22 are moved from the stored configuration (as shown in
It should be appreciated by those having ordinary skill in the related art that the sponsons 22 can be secured to the exterior surface of the top of the kayak 10 (when in the stored configuration) by any suitable means, including but not limited to rubber bands, bungee cords, clips, hooks, hook and loop fastener, or any other conventional releaseable fasteners. By way of example only and not by way of limitation, each sponson 22 is preferably snap-fitted onto the surface of the kayak 10.
It should be appreciated by those having ordinary skill in the related art that the sponsons 22 can have any suitable structural relationship with the kayak 10. It should also be appreciated that each sponson 22, in general, including the support arm 28 and float 30, can have any suitable structure, shape, and size and be made of any suitable material to provide added buoyancy to the kayak 10 and create a grappling point for the kayaker in the water. For example, the support arms 28 can be between about 2 feet and about 15 feet in length. Alternatively, the support arms 28 can be longer than 15 feet. In preferred example embodiments, the support arms 28 are approximately half of the kayak's length. Additionally, the float 30 does not have to include any holes 32, or can include two or more holes as desired. It should also be appreciated that the support arm 28 and float 30 can have any suitable structural relationship with each other. For instance, the float 30 can be fixedly or pivotally attached to the free end of the support arm 28. In preferred example embodiments, the float 30 is pivotally attached thereto. It should also be appreciated that the support arm 28 can be partially hollow or solid. It should also be appreciated that the stability system 20 can include any suitable number of sponsons 22, including more than two.
Referring now to
It should be appreciated by those having ordinary skill in the related art that each of the sponsons 22 can be movably attached to the kayak 10 by any suitable means. It should also be appreciated that the stabilizing mechanism 36 can have any suitable shape, size, structure and structural relationship with the kayak 10. It should also be appreciated that the linkage member 38 and sponson support member 40 can have any suitable relationship with each other and the kayak 10.
Referring back to
The stabilizing arm 24 is substantially tubular in shape and generally has a diameter that is similar to the diameter of the support arm 28 of the sponson 22. In example embodiments, the diameter of the stabilizing arm 24 is between about 1 inch to about 5 inches—although in alternative embodiments the diameter can be less than 1 inch or greater than 5 inches as desired. The stabilizing arm 24 is also generally shorter than the length of the sponson support arms 28, but can be any length as desired. As explained earlier, the stabilizing arm 24 preferably hugs the exterior of the kayak 10, in the stored configuration, such that a kayaker in the water can immediately and readily manually pivot and deploy the stabilizing arm 24 outward from the respective side of the kayak 10. Also in this way, the kayaker, being located in the cockpit 14, can immediately and readily manually pivot and retract the stabilizing arm 24 inward to the respective side of the kayak 10 as desired. In the deployed configuration of the stability system 20, the sponson 22 and stabilizing arm 24 are disposed substantially parallel with each other and preferably, perpendicular to the kayak 10. However, in other embodiments, the arrangement of the stabilizing arm 24 and corresponding sponson 22 can be configured alternatively as desired. In example embodiments of the stability system 20 in the stored configuration, the sponson 22 and stabilizing arm 24 are disposed substantially parallel with each other and parallel with the kayak's exterior. In preferred example embodiments, the stabilizing arm 24 is made of metal. In alternative embodiments, the stabilizing arm can be formed from plastic, rubber, wood, or other materials as desired.
It should be appreciated by those having ordinary skill in the related art that the stabilizing arms 24 can have any suitable structural relationship with the kayak 10. It should also be appreciated that each stabilizing arm 24 can have any suitable structure, shape, and size and be made of any suitable material to provide support to the kayaker in the water. It should also be appreciated that the stabilizing arm 24 can have any suitable range of motion. However, in example embodiments, the stabilizing arm 24 is pivotally coupled to the kayak 10 as shown in the drawing figures. With particular reference to
In operation, the kayak stability system 20 serves to assist a kayaker (or other vessel occupant) to enter the kayak 10 from the water. For example, once a kayaker has left the cockpit 14 of the kayak and has gotten into the water—either willfully or accidentally—it can be very difficult to reenter the kayak. The stability system 20 assists the kayaker in the following manner. Initially, once in the water, it is anticipated that the kayaker will “upright” the kayak (if necessary) such that the hull is properly floating in the water. Then, the kayaker can manually pivot the at least one—and preferably two—sponsons 22 from a stored configuration to a deployed configuration out over and onto the water. In doing such, the kayaker manually rotates the support arm 28 of the sponsons 22 away from the side of the kayak 10. In the deployed configuration, the kayak 10 is buoyed and stabilized by the sponsons 22. Next, the kayaker can manually pivot the at least one stabilizing arm 24 away from the side of the kayak 10. Once the sponsons 22 and stabilizing arm 24 are deployed, the kayaker can utilize one or more of the support arms 28 and/or the stabilizing arm 24 to hold onto for support while the kayaker removes water from the kayak cockpit (if necessary). When the kayaker is ready to reenter the kayak, the kayaker can use one or more of the support arms 28 and/or the stabilizing arm 24 as fulcrums or leverage points to hoist himself/herself into the cockpit 14 of the kayak 10. Once the kayaker is back into the cockpit 14, the kayaker can manually pivot the sponsons 22 and stabilizing arm 24 back into the stored configuration and revisit his/her kayaking activities.
It should be noted that the kayak stability system 20 of the present invention can be packaged and sold as a retrofit kit to allow existing kayak owners to modify existing kayaks. As such, existing kayak owners can modify their kayaks to include one or more sponsons 22 and/or one or more stabilizing arms 24 as described above. The retrofit kit can also include some or all of the fasteners and support mechanisms describe herein to assist the kayak owner in implementing the kayak stability system 20 on their existing kayak. It should be appreciated that there are numerous ways to attach the sponsons and/or stabilizing arms to an existing kayak, and the present invention is not limiting in this regard. However, optionally, a retrofit kit according to the present invention can also include at least one stabilizing mechanism 36 as described above for pivotally coupling the at least one sponson 22 to the kayak 10 and for linking together and stabilizing multiple sponsons 22. Additionally, the retrofit kit can also optionally include at least one stabilizing arm support member 42 for pivotally coupling the at least one stabilizing arm 24 to the kayak 10.
It should also be noted that the kayak stability system can be incorporated into and sold together with new kayaks. In this respect, another example form of the present invention includes a kayak 110 having a built-in stability system 120, as shown in
In example embodiments according to another form of the present invention, as depicted in
In still another embodiment of the present invention the kayak 10 can also include an adjustable and removable set of “training sponsons” (not depicted) to provide stability to the kayak for, say, beginner kayakers learning to kayak or disabled or physically challenged kayakers. The set of training sponsons can be adapted to permit such a kayaker to become accustomed to operating the kayak 10 without overturning it and help him or her keep upright so that the kayaker can learn how to paddle the kayak. As the skill of the kayaker progresses, the set of training sponsons can be adjusted accordingly until they can eventually be removed from the kayak permanently. Optionally, the training sponsons are adjustable in both size and the amount of floatation assistance provided to accommodate the new “paddler” to learn how to paddle the kayak.
As can easily be seen, the kayak stability system of the present invention adequately assists beginner, relatively weak or unfit, and/or disabled or physically challenged kayakers, such as those who are paraplegics, quadriplegics, or amputees. More specifically, the kayak stability system adequately assists such kayakers to conveniently enter or re-enter the kayak cockpit from the water. In particular, the kayak stability system does not require the kayaker, especially one who is paraplegic, to use any of his or her leg strength to get into the cockpit from the water. Also, the kayak stability system of the present invention is relatively more convenient and less labor-intensive and time-consuming to use than known stability devices. Furthermore, the kayak stability system does not affect operation or performance of the kayak. Finally, the kayak stability system adequately stabilizes the kayak in the water to minimize or even eliminate a possibility of the kayak overturning in the first place—especially when the water is perilously wavy.
The present invention has been described in an illustrative manner. It is to be understood that the terminology that has been used is intended to be in the nature of words of description rather than of limitation. Many modifications and variations of the present invention are possible in light of the above teachings. Therefore, the present invention may be practiced other than as specifically described.
