Abstract
An assembly, comprised of four rigid members, to facilitate manual carrying and portaging of a water craft, by a single person. This assembly is so constructed as to allow easy attaching to, and removal from, this craft. The two members of this assembly that are longitudinally aligned to the craft are of predetermined dimensions as to facilitate the comfortable transport of this craft upon the shoulders of a person. The remaining two rigid members are adapted as to allow secure yet adjustable fit to a broad range of water craft by predetermined means. This invention, when not in use, quickly and easily disassembles so that all components may be stored efficiently in or on the said craft.
Description
CA 0220~980 1997-0~-30 Description This invention, entitled the DW Carry System, relates to the manual carrying and portaging of many types of infl~t~ble water craft, kayaks, and similar craft. This system is designed to be used by one person while they carry such a craft.
The use of these types of water craft is growing in waterways once domin~ted by the traditional open decked touring canoe. This expansion has been restricted by difficulties in portaging these craft.
This problem is compounded when the distance traversed becomes lengthy.
The craft that this invention relates to, do not allow a comfortable hold upon them during carrying. Whereas, traditional canoes have gunwales to hold and thwarts or yokes to distribute their weight on the carrier during a portage; most other types of paddled craft do not have such structures or members. Thus, common practice in the carrying of kayaks, is to hook one's shoulder into the craft's cockpit; there by transferring the boat's weight to your shoulder. This creates significantly greater load on one side of your body, along with the resulting discomfort. Tnfl~t~bles and sit-on-tops rely on a shoulder strap, straps, or nothing at all for single person carrying. Many of the newer white water canoes have no yokes. They often do have central saddles to contend with during portages, and some rodeo canoes no longer have gunwales.
There exists currently a number of carry systems, for these types of craft, involving one or more straps. All of these work well over short distances. Over long portages, none of these systems compare favorably to the ease and comfort with which a canoe of equal weight may be portaged. In use, these strap based systems were found to situate the crafts weight to one side of the carrier's body, or align the craft lengthwise against his or her back. Both of these carrying positions proved uncomfortable on all hut the shortest of portages.
There were rigid member manual carry systems found for kayaks and like craft. One consisted of a yoke, like that found on a conventional canoe. In producing and testing this device, it was found to lack clearance for the head, relative to the kayak. This device is based on a single, relatively straight, rigid member; Thus, the carrier's head is mostly contained within the cock pit when this system is used.
CA 0220~980 1997-0~-30 This system required a cockpit rim to fasten to; It did not work on inflatable kayaks, sit-on-tops or inflatable rafts.
Another rigid member type manual carry system was fixed about the head of the person carrying the craft. This could be dangerous when used over irregular ground.
A better manual carry system, for these types of craft, must fill the following criteria: the efficient transfer of the craft's weight to the person carrying it, the efficient positioning of the craft's load relative to the person carrying the craft, the carry system mustn't interfere with the particular use for which the craft is intended, the carry system must evenly distribute the craft's load to both shoulders of the person carrying this craft, the carry system must be small enough to facilitate easy storage in or on the craft when said system is not in use and one model manual carry system should ~lt a number of similar water craft.
In drawings which illustrate embodiments of this invention:
Figure 1 is showing one embodiment of this invention.
Figure 2 is showing the embodiment of this invention, as shown in Figure 1, in use with one kayak design.
Figure 3 is showing details of the straps, their attachment and adjustment fittings, as shown in Figure 1.
Figure 4 is showing the details of a cross member attachment that is fixed in place by a release pin as shown in Figure 1, but without the strap. ( one of two such attachments ) Figure 5 is showing details of a cross member attachment having travel along part of one padded member as shown in Figure 1, but without the strap.~ one of two such attachments ) Figure 6 is showing a backpack with external frame so modified as to allow it's frame to act as if it were the carrier's shoulders during the use of this invention.
Figure 7 is showing one embodiment of this invention so adapted as to attach to an infl~t~ble craft by means of four fasteners.
This invention's efficiency in ca~rying a water craft 5 is found in the rigidity that is achieved between craft 5 and invention, as shown in one embodiment, Figure 2. The straps 1 are tightened up via the buckles 13, then tensioned by the tension devices 2 and their ret~ining buckles 14. Thus allowing the pads 3 to transfer the load evenly and efficiently to the carrier's shoulders 4 as if the invention were a fixed part of the craft 5.
CA 0220~980 1997-0~-30 This invention disassembles and assembles quickly. It's disassembled components fit into a small package size; also, the preferred embodiment of this invention leaves no fixtures on the craft 5 when not in use. Thus guaranteeing that there will not be interference with the craft's 5 intended use. Please note that some embodiments of this invention do leave fittings on the craft. These embodiments are only intended for usage were they will not compromise the craft's intended use.
Each embodiment of this invention will fit numerous models and types of craft. This is achieved, on the preferred embodiment as in Figure 1, via the adjustment range with the straps 1 and the sliding of the cross member 6. On an embodiment as in Figure 7, fittings must be attached to the craft. The Figure 7 version is of use on multiple craft, so long as these craft are fitted to accept such attachments. This version, Figure 7, has been shown to not inhibit the use of most infl~t~les and some white water canoes.
The preferred embodiment of this invention, as shown in Figure 1, is assembled by first sliding the cross member 6 and it's fittings 10 onto the two padded 3 member's 7 shafts via the unpadded ends 11.
Then the other cross member 8 is slid onto the member's 7 unpadded ends 11 and fixed in place by the release pins 12. This in turn acts to contain the motion of the cross member 6, between the other cross member 8 and the pads 3 on the other ends of these padded 3 members 7. Now this embodiment of the invention appears as in Figure 1, and is ready for the straps 1 to be attached around the craft 5 using the buckles 13. Final tensioning is by the action of the tension devices 2 and their ret~ining buckles 14.
The location of attachment of the invention on the craft 5 is determined by the need to situate the crafts longit~ldin~l center of gravity 14 above the person's shoulders 4 carrying the craft 5, as shown in Figure 2. Once this invention's mounting position is determined it can be marked temporarily, or permanently, on the craft.
The positioning of the sliding cross member 6 will determine the angle, relative to the horizon, at which the craft 5 is carried. This angle will vary with each embodiment of this invention and model of craft carried. When the choice of position is made, for one embodiment of this invention and one kayak, marks may be made on the assembly to aid in efficient duplication of this position.
CA 0220~980 1997-0~-30 The preferred embodiment of this invention, Figure 1, is made up of four rigid tubular members 6, 7, 8. These members are attached to one another via four polyethylene fittings 9, 10. The sliding cross member 6 has two fittings 10 on its shaft being fixed in position by two pins 15. The other cross member 8 has two smaller f1ttings 9 fixed in position by two pins 16. The entire assembly is fixed together with the two release pins 12. These pins 12 fix the two padded members 7 in the ftting~ 9 on the cross member 8.
This preferred embodiment is constructed using: marine grade aluminum tubing for the four rigid members 6,7,8, UHMW
polyethylene for the four fittings 9, 10, solid stainless pins for the four fixed attachment points 15, 16 and the strap retention pins 19, marine grade stainless release pins 12 for the two detachable assembly points, neoprene foam for the pads 3 and anti scuff plates 17, nylon webbing for the strapping 1, derlin for the buckles 13, 14 and loops 18, and aluminum for the tension devices 2.
One embodiment, Figure 1, of this invention has been shown to function well on a large variety of craft. These include two person infl~t~ble rafts, roto-molded kayaks, blow-molded kayaks, infl~t~ble kayaks, folding kayaks, infl~t~ble canoes, sea kayaks and sit-on-tops.
Other embodiments of this invention also increase the clearance for the carrier's head while m~int~ining the craft parallel to the ground.
Thus allowing it's use with surf boards, wave boards and wind surfers.
This invention also worked well in combination with a backpack.
Figure 6 is showing such a backpack, so altered as to transmit the craft's weight to the carrier's hips instead of his or her shoulders.
Those backpacks, found adequate, utilize either an interior or exterior frame 20. Those backpacks having sufficient structural integrity as to transfer the predetermined load from the packs top to its hip belt 21 could be made to function with this invention. However, most of the internal frame packs needed extensive modifications and additions.
Accordingly, a rigid or semi-rigid external frame was found to be best in this application.
Such a backpack's frame, need only be notched 22 on top, leaving the center raised 23. This raised portion 23 protects the carrier's neck while using this invention in combination with this backpack. The resulting backpack's top profile substitutes for the carrier's shoulders and neck, and in doing so, it also centers the craft's weight over the carrier's head.
This invention can also be secured by four fasteners 24, 25 as shown in Figure 7. This embodiment was found to be best suited to infl~t~hle craft, and white water canoes, where half of the fastener 25 could be glued to the hull material. This decreases the ease with which this invention may be transferred between craft, however, it speeds attachment and removal of this carry system from a craft so fitted. This embodiment also decreases overall weight carried.
The use of these types of water craft is growing in waterways once domin~ted by the traditional open decked touring canoe. This expansion has been restricted by difficulties in portaging these craft.
This problem is compounded when the distance traversed becomes lengthy.
The craft that this invention relates to, do not allow a comfortable hold upon them during carrying. Whereas, traditional canoes have gunwales to hold and thwarts or yokes to distribute their weight on the carrier during a portage; most other types of paddled craft do not have such structures or members. Thus, common practice in the carrying of kayaks, is to hook one's shoulder into the craft's cockpit; there by transferring the boat's weight to your shoulder. This creates significantly greater load on one side of your body, along with the resulting discomfort. Tnfl~t~bles and sit-on-tops rely on a shoulder strap, straps, or nothing at all for single person carrying. Many of the newer white water canoes have no yokes. They often do have central saddles to contend with during portages, and some rodeo canoes no longer have gunwales.
There exists currently a number of carry systems, for these types of craft, involving one or more straps. All of these work well over short distances. Over long portages, none of these systems compare favorably to the ease and comfort with which a canoe of equal weight may be portaged. In use, these strap based systems were found to situate the crafts weight to one side of the carrier's body, or align the craft lengthwise against his or her back. Both of these carrying positions proved uncomfortable on all hut the shortest of portages.
There were rigid member manual carry systems found for kayaks and like craft. One consisted of a yoke, like that found on a conventional canoe. In producing and testing this device, it was found to lack clearance for the head, relative to the kayak. This device is based on a single, relatively straight, rigid member; Thus, the carrier's head is mostly contained within the cock pit when this system is used.
CA 0220~980 1997-0~-30 This system required a cockpit rim to fasten to; It did not work on inflatable kayaks, sit-on-tops or inflatable rafts.
Another rigid member type manual carry system was fixed about the head of the person carrying the craft. This could be dangerous when used over irregular ground.
A better manual carry system, for these types of craft, must fill the following criteria: the efficient transfer of the craft's weight to the person carrying it, the efficient positioning of the craft's load relative to the person carrying the craft, the carry system mustn't interfere with the particular use for which the craft is intended, the carry system must evenly distribute the craft's load to both shoulders of the person carrying this craft, the carry system must be small enough to facilitate easy storage in or on the craft when said system is not in use and one model manual carry system should ~lt a number of similar water craft.
In drawings which illustrate embodiments of this invention:
Figure 1 is showing one embodiment of this invention.
Figure 2 is showing the embodiment of this invention, as shown in Figure 1, in use with one kayak design.
Figure 3 is showing details of the straps, their attachment and adjustment fittings, as shown in Figure 1.
Figure 4 is showing the details of a cross member attachment that is fixed in place by a release pin as shown in Figure 1, but without the strap. ( one of two such attachments ) Figure 5 is showing details of a cross member attachment having travel along part of one padded member as shown in Figure 1, but without the strap.~ one of two such attachments ) Figure 6 is showing a backpack with external frame so modified as to allow it's frame to act as if it were the carrier's shoulders during the use of this invention.
Figure 7 is showing one embodiment of this invention so adapted as to attach to an infl~t~ble craft by means of four fasteners.
This invention's efficiency in ca~rying a water craft 5 is found in the rigidity that is achieved between craft 5 and invention, as shown in one embodiment, Figure 2. The straps 1 are tightened up via the buckles 13, then tensioned by the tension devices 2 and their ret~ining buckles 14. Thus allowing the pads 3 to transfer the load evenly and efficiently to the carrier's shoulders 4 as if the invention were a fixed part of the craft 5.
CA 0220~980 1997-0~-30 This invention disassembles and assembles quickly. It's disassembled components fit into a small package size; also, the preferred embodiment of this invention leaves no fixtures on the craft 5 when not in use. Thus guaranteeing that there will not be interference with the craft's 5 intended use. Please note that some embodiments of this invention do leave fittings on the craft. These embodiments are only intended for usage were they will not compromise the craft's intended use.
Each embodiment of this invention will fit numerous models and types of craft. This is achieved, on the preferred embodiment as in Figure 1, via the adjustment range with the straps 1 and the sliding of the cross member 6. On an embodiment as in Figure 7, fittings must be attached to the craft. The Figure 7 version is of use on multiple craft, so long as these craft are fitted to accept such attachments. This version, Figure 7, has been shown to not inhibit the use of most infl~t~les and some white water canoes.
The preferred embodiment of this invention, as shown in Figure 1, is assembled by first sliding the cross member 6 and it's fittings 10 onto the two padded 3 member's 7 shafts via the unpadded ends 11.
Then the other cross member 8 is slid onto the member's 7 unpadded ends 11 and fixed in place by the release pins 12. This in turn acts to contain the motion of the cross member 6, between the other cross member 8 and the pads 3 on the other ends of these padded 3 members 7. Now this embodiment of the invention appears as in Figure 1, and is ready for the straps 1 to be attached around the craft 5 using the buckles 13. Final tensioning is by the action of the tension devices 2 and their ret~ining buckles 14.
The location of attachment of the invention on the craft 5 is determined by the need to situate the crafts longit~ldin~l center of gravity 14 above the person's shoulders 4 carrying the craft 5, as shown in Figure 2. Once this invention's mounting position is determined it can be marked temporarily, or permanently, on the craft.
The positioning of the sliding cross member 6 will determine the angle, relative to the horizon, at which the craft 5 is carried. This angle will vary with each embodiment of this invention and model of craft carried. When the choice of position is made, for one embodiment of this invention and one kayak, marks may be made on the assembly to aid in efficient duplication of this position.
CA 0220~980 1997-0~-30 The preferred embodiment of this invention, Figure 1, is made up of four rigid tubular members 6, 7, 8. These members are attached to one another via four polyethylene fittings 9, 10. The sliding cross member 6 has two fittings 10 on its shaft being fixed in position by two pins 15. The other cross member 8 has two smaller f1ttings 9 fixed in position by two pins 16. The entire assembly is fixed together with the two release pins 12. These pins 12 fix the two padded members 7 in the ftting~ 9 on the cross member 8.
This preferred embodiment is constructed using: marine grade aluminum tubing for the four rigid members 6,7,8, UHMW
polyethylene for the four fittings 9, 10, solid stainless pins for the four fixed attachment points 15, 16 and the strap retention pins 19, marine grade stainless release pins 12 for the two detachable assembly points, neoprene foam for the pads 3 and anti scuff plates 17, nylon webbing for the strapping 1, derlin for the buckles 13, 14 and loops 18, and aluminum for the tension devices 2.
One embodiment, Figure 1, of this invention has been shown to function well on a large variety of craft. These include two person infl~t~ble rafts, roto-molded kayaks, blow-molded kayaks, infl~t~ble kayaks, folding kayaks, infl~t~ble canoes, sea kayaks and sit-on-tops.
Other embodiments of this invention also increase the clearance for the carrier's head while m~int~ining the craft parallel to the ground.
Thus allowing it's use with surf boards, wave boards and wind surfers.
This invention also worked well in combination with a backpack.
Figure 6 is showing such a backpack, so altered as to transmit the craft's weight to the carrier's hips instead of his or her shoulders.
Those backpacks, found adequate, utilize either an interior or exterior frame 20. Those backpacks having sufficient structural integrity as to transfer the predetermined load from the packs top to its hip belt 21 could be made to function with this invention. However, most of the internal frame packs needed extensive modifications and additions.
Accordingly, a rigid or semi-rigid external frame was found to be best in this application.
Such a backpack's frame, need only be notched 22 on top, leaving the center raised 23. This raised portion 23 protects the carrier's neck while using this invention in combination with this backpack. The resulting backpack's top profile substitutes for the carrier's shoulders and neck, and in doing so, it also centers the craft's weight over the carrier's head.
This invention can also be secured by four fasteners 24, 25 as shown in Figure 7. This embodiment was found to be best suited to infl~t~hle craft, and white water canoes, where half of the fastener 25 could be glued to the hull material. This decreases the ease with which this invention may be transferred between craft, however, it speeds attachment and removal of this carry system from a craft so fitted. This embodiment also decreases overall weight carried.
