Description:
A live bait containment system for a watercraft hatch

Field of the Invention

[1] This invention relates generally to live bait containment systems and, more particularly, this invention relates to a l ive bait containment system for rapid tem porary installation within existing watercraft hatch es.

Background of the Invention

[2] Live bait containment systems for watercraft such as kayaks of various configurations exist including US 6354238 B1 (M OLESWORTH et al .) 12 M arch 2002 [hereinafter referred to as Dl] which discloses a collapsible ba it tank apparatus having a hinged interior sealing ring mated to a bladder. The hinged interior sea ling ring is folded to fit th rough a hul l hatch whereafter it is opened and clam ped to the hul l with an exterior seal ing ring.

[3] US 20070012236 Al (CAPLES) 18 January 2007 [hereinafter referred to as D2] discloses a motorised kayak having a bait tank integrally formed within the hul l. The floor of the tank of D2 may have a pum p and inlet which draws water in from beneath the hull into the tank and a drain.

[4] US 20160031533 Al (ROBLES) 04 February 2016 [hereinafter referred to as D3] discloses a fibreglass canoe having a n insulated l ive well tank integra lly formed within the hull .

[5] However, im provements to live containment systems are desirous and the present invention seeks to provide a system which overcomes or substantially amel iorate at least some of the deficiencies of the prior art, or to at least provide an alternative.

Summa ry of the Disclosure

[6] There is provided herein a l ive bait containment system for a hatch of a watercraft, such as a kayak.

[7] The present system has been designed for rapid instal lation and removal within an existing hatch as opposed to being permanently integral ly formed as are the prior art tank arrangements of D2 and D3.

[8] The present system has a hatch interfacing col lar can be screwed into an existing hatch plate of the kayak. The present system may therefore be installed within a foot wel l hatch so as to be conveniently accessible between one's legs in use for accessing l ive bait and temporary storage of catch. [9] The hatch interfacing collar has a pa rticular configuration to al low for swift installation and removal as com pared to the arrangement of Dl.

[10] Specifical ly, the hatch interfacing collar has an entrance leading to a n underside mouth that engages a flexible bladder in a fluid tight manner.

[11] The hatch interfacing col lar may further com prise a male interface and adjacent annul us which screws into a corresponding female interface of the hatch plate and clam ps against the hatch plate.

[12] The present arrangement is therefore superior in the way in which it can be quickly and easily tem porarily instal led within the hatch . Specifical ly, when em pty, the col lapsed bladder can easily fit through the hatch. Once inside, and when fil led with water, the bladder is able to distend to a diameter greater than that of an inner diameter of the hatch.

[13] Removal of the present system may further com prise disconnecting the hatch interfacing collar and manipulating the flexible water laden bladder out of the hatch or alternatively em ptying the bladder prior removal.

[14] In this way, the present system can be installed and removed m uch quicker than the arrangement of D l. Specifically, the hinged interior seal ing ring of D l requires folding for insertion via the hatch whereafter it is secured with an exterior seal ing ring secured thereto by fasteners. This is a difficult instal lation procedure and is therefore su itable for a more permanent installation.

[15] Conversely, the present system may be installed and removed in a matter of seconds as outlined above, thereby being suitable for removal after each use for cleaning, storage and the like.

[16] Furthermore, the present system com prises a pum p for aeration and/or water replenishment. The pum p is configu red to pum p via the ent rance such that supply hosing can be conveniently run exteriorly as opposed to the arrangement of Dl wherein the water supply hoses run directly from the bladder as opposed to via the seal ing ring of Dl. As such, the hosing of Dl m ust be run th rough the hu ll. As such, not only is it difficult to access the hoses of Dl for installation (one would need to be able to access the bladder via the seat to connect the hoses), the interior reticulation of the hosing of D l com prom ises the watertightness of the hul l i n the event of a leak.

[17] In a preferred em bodiment, pum p is configured to pum p through a sidewall of the entrance into the bladder thereunderneath so as to not obstruct the opening.

[18] In a preferred em bodiment, the entrance is raised such that the sidewal l is substantial ly vertical . The raised inference may be cyl indrical and defining the opening coaxial ly therethrough. As such, when the hatch interfacing col lar is engaged to the hatch, suction and drain hosing may be conveniently run radial ly through the sidewall to edges of the kayak or through foot wel l drains thereof without having to pass through the opening.

[19] Furthermore, the pum p may be attached to an exterior of the sidewall, so as to allow for convenient non-submerged access and operation in use.

[20] In em bodiments, the male interface com prises threading for screw fit engagement with hatches of conventional configurations, thereby allowing for utilisation of the present system with conventional kayaks.

[21] However, in em bodiments, the present system may com prise an adapter plate which may be engaged or screwed to the hatch. I nterface adapter plate may com prise an interior female interface to which the exterior of the male interface mates.

[22] In em bodiments, the male interface may be configured to l im it rotation of the engagement during installation or removal, thereby reducing twisting of the hosing extended radially therefrom . In em bodiments, the male interface com prises radial locking tabs which interface with corresponding slots of the interface adapter or hatch. The slots are configured to accept the locking tabs for partway rotation (such as by less than 45°) twist lock engagement at term inal ends thereof.

[23] According to one aspect, there is provided a live bait containment system for a watercraft hatch, the system com prising a hatch interfacing collar having an underside male interface configured for releasable securement with a female male interface of a permanently affixed hatch plate in use, the col lar havi ng an underside mouth to which a bladder is engaged in a fluid tight manner, the bladder capable of distending to a diameter greater than that of the male interface, wherein the system com prises an upper entrance defining an opening into an interior of the bladder thereunderneath and a pum p which pum ps via the entrance into the bladder.

[24] The entrance may have a side wal l and wherein the pum p pum ps through a sidewall of the entrance.

[25] The sidewall may be substantial ly vertical such that the entrance may be rai sed with respect to the male interface.

[26] The pum p may be affixed to an exterior surface of the sidewal l.

[27] The exterior surface may com prise a pum p body connector to which the pum p may be releasably connected. [28] The pum p may be a water pum p and wherein the system further may com prise a suction hose leading to the water pum p which pumps water therefrom through the at least one side wal l.

[29] The l ive bait containment may further com prise an interior hose leading from an interior of the side wall to within the bladder .

[30] The suction hose may com prise an annular bung for frictional engagement within a drainhole of the watercraft in use.

[31] A distal end of the suction hose may com prise a sinker.

[32] The l ive bait containment may further com prise a drain hose through the at least one side wal l.

[33] The pum p may be configured to fill the system to the level of the drain hose.

[34] The drain hole passes through the at least one sidewal l via a n exit aperture and wherein the exit aperture may be above the male interface.

[35] The exit aperture may be within 2 cm of a rim of the entrance.

[36] The pum p may be an a ir pum p and wherein the system pum ps air through the at least one side wal l.

[37] The live bait containment may further com prise an interior hose from an inner of the side wall to within the bladder.

[38] The male interface may com prise radial interlocking tabs configu red for press in and partway rotation interlock with slots of the hatch plate.

[39] Partway rotation may be less than 45° of rotation.

[40] The hatch plate may be an adapter plate com prising a further male interface configured for interfacing with a further hatch plate and having an interior female interface configured for interfacing with the male interface.

[41] The live bait containment may further com prise a l id which fits the entrance.

[42] The lid may be a pop top lid in that it may com prise an inner annul us which frictionally engages a rim of the entrance.

[43] The entrance may be cylindrical .

[44] According to another aspect, there is provided a method of using of a live bait containment system as described herein, the method com prising inserting the bladder through the hatch plate and engaging the male interface to the hatch plate and then operating the pum p to pum p water through the entrance to fill the bladder.

[45] Other aspects of the invention are also discl osed. Brief Description of the Drawings

Description of Embodiments

[53] Figure 1 shows a perspective view of a fishing kayak 100 having a hul l 101 of conventional configuration. Figure 2 shows a respective top plan view thereof.

[54] The kayak 100 may com prise a seat 115 having a foot well 104 thereinfront for seated use with legs aside a fishing rod 102 which may be held with a fishing rod holder 103. The hull 101 may comprise a forward storage com partment 106 and access hatch 107 therefor, typical ly enclosed with a l id and used for storage of personal items and use such as sunscreen, replenishments and the like. The hatch 107 may com prise a hatch plate 158 to which the lid is engaged . The hul l 101 may have other storage com partments 116 in em bodiments.

[55] The foot well 104 may com prise drains 105 therethrough.

[56] A live bait containment system 108 may be used to store l ive bait and catch within the storage space 106 of the kayak 100.

[57] The system 108 may com prise a hatch interfacing col lar 113 which engages the hatch plate 158 in em bodiments. The hatch interfacing col lar 113 is of a particular configuration for quick installation and removal.

[58] The hatch interfacing collar 113 may com prise an annul us 117 and male interface 119 for releasable engagement of a female interface of the hatch plate 158 in use. When the male interface 119 screws into or otherwise interlocks with the female interface of the hatch plate 158, the annul us 117 may clam p thereagainst, preferably in a water tight manner.

[59] Whereas the male interface 119 may be configured for engagement with hatch plates 158 of conventional configuration s, in em bodiments, the male interface 119 may be configured for engagement of an adapter plate 111 in em bodiments. Various adapter plates

111 may be provided to allow for engagement of the hatch engaging interface collar 113 of uniform configuration .

[60] The hatch interfacing col lar 113 may com prise an underside mouth 120 to which a flexible bladder 112 is connected in a fluid tight manner. The hatch interfaci ng collar 113 has an opening 124 to the mouth 120 for accessing the interior of the bladder 112 thereunderneath.

[61] The system 108 com prises a pum p 114 which may pum p air and/or water via the hatch engaging col lar 113 down into the bladder 112 thereunderneath.

[62] For water replenishment, the system 108 may com prise a suction hose 109 reaching beneath the water level 155 and a drain hose 110.

[63] With reference to Figure 3, there is shown a cross -sectional view of the system 108 installed within the hull 101.

[64] As can be seen, the male interface 119 of the hatch interfacing collar 113 has been screwed or otherwise engaged into the female interface of the hatch plate 158 or adapter plate 111 such that the annul us 117 clam ps thereatop.

[65] The pum p 114 may draw water in via a suction hose 109, a distal end of which extends beneath an adjacent water level 155. I n the em bodiments shown, the suction hose 109 may be reticulated through the footwell drain 105 and may be held in place by a n annular bu ng 141 engaged within the drain 105. Alternatively, the suction hose 109 may be run over the edge of the hull 101 and held beneath the water level 155 by a sinker 142.

[66] The pum p 114 may pum p via the interior hose 139 extending to wel l into the bladder

112 for adequate circulation.

[67] The drain hose 110 may al low excess water to flow from the system 108, sim ilarly via an opposite footwel l drain 105 or over the edge of the hul l 110.

[68] In em bodiments, the pum p 144 may pum p air via the interior hose 139 well into the bladder 112 for aeration. I n accordance with this em bodiment, the pum p 114 may draw from air surround ing the hatch interfacing collar 113, thereby negating the need for opposing 109, 110. [69] Figure 4 shows a preferred em bodiment of t he hatch interfacing collar 113 wherein the hatch interfacing collar 113 com prises a raised entrance 121, typically cyl indrical. The raised entrance 121 extending above the an nulus 117 conveniently presents an opening 124 therethrough while exposing at least one sidewal l through which the hoses 110 may be run through, thereby conveniently extending radia lly and not passing via the opening 124.

[70] Furthermore, in the em bodiment shown, the pump 114 may be adhered to the sidewal l of the raised entrance 121, thereby allowing for easily accessible, serviceable and controllable non-submerged operation .

[71] The inlet hose 109 may feed into the pum p 114 which may then pum p though the sidewal l via the interior hose 139 into the bladder 112.

[72] The drain hose 110 may feed through an apertu re 156 of the sidewall of the raised entrance 121. As such, water pum ped into the bladder 112 by the pum p 114 reaches the level of the aperture 156 whereafter it flows via the drain hose 110. As such, the water level may be substantial ly right to the level of the opening 124.

[73] The opening 124 may be selectively enclosed by a pop top lid 122 which may be pivotal ly engaged the raised entrance 121 by way of live hinge 157. The lid 122 may com prise an inner annul us 123 for frictional engagement against th e rim of the opening 124.

[74] An exterior of the engaging annul us 119 may comprise mating formations thereon for interfacing with the hatch plate 158 or adapter plate 111. In em bodiments, the mating formations may com prise threading so as to allow for the screwing in of t he hatch interfacing col lar 113 into the hatch plate 158.

[75] Flowever, especially with hosing 109, 110 extending readily therefrom, excessive rotation of the hatch interfacing col lar 113 and therefore twisting of the hosing 109, 110 may be undesirous and therefore the exterior of the male interface 119 may com prise radial locking tabs 118 which interface with corresponding slots 128 of the adapter plate 111 to allow pushing in partway rotation engagement at term inal ends thereof. Partway rotation may be rotation of less than 45° in em bodiments.

[76] The mouth 120 may be sim ilarly cylindrical and coaxial ly located with respect to the engagement male interface 119. The mouth 120 may com prise the same interior diameter as that of the opening 124 of the raised entrance 121.

[77] Figure 5 shows a top perspective exploded representation of the constituent com ponents of the system 108 com prising the hatch interfacing col lar 113, optional adapter plate 111, hatch plate 131 and bladder 112 [78] As is il lustrated, the engagement male interface 119 has the interlocking tabs 118 which slot into the corresponding slots 128 of the optional adapter plate 111. As such, the interface 130 may be quickly connected and disconnected from the adapter plate 111 without unnecessarily tangling the hoses 109, 110.

[79] Figure 5 further shows the entrance 121 extending proud of the engaging ann ul us 117 such as by more than 2 cm and preferably more than 5 cm in em bodiments, thereby allowing a sidewal l of sufficient height to accom modate the pum p 114 on an exterior surface thereof and to al low for the reticulation of hoses 109, 139 and 110 therethrough.

[80] Figure 5 shows the mouth 120, preferably cyl indrical, around which a neck 137 of the bladder 112 may be engaged with a com pression band 135 such as a worm-drive hose clam p in a fluid tight manner.

[81] When engaged in this manner, the system exposes the opening 124 which leads via the mouth 120 into an opening 138 of the bladder 112 to access contents within a body 136 thereof.

[82] Figure 6 shows an exemplary electrical schematic 143 of the present system 108.

[83] As is shown, the system 108 may com prise a battery 144 for pum p power supply. I n an em bodiment, the system 108 may com prise a water pum p 145 operably coupled to the battery 144 and selectively powered by way of a switch 146 to pum p water via a water pum p inlet 151 and out via a water pum p outlet 152. The water pum p inlet 151 may be connected to the suction hose 109 and the water pum p outlet 152 may be connected to the interior hose 139.

[84] In further em bodiments, the system 108 may com prise an air pum p 147 operably coupled to the battery 144 so as to pum p air via an air inlet 153 and out via an a ir outlet 154. The air outlet 154 may be connected to the interior hose 139.

[85] In one em bodiment, the system 108 com prises either the water pum p 145 or the air pum p 147. Flowever, in em bodiments, the system 108 may com prise both. I n em bodiments, the raised entrance 129 may com prise a connector allowing for the substitution of either a water pum p 145 or an air pum p 147 so as to configure the appl ication thereof.

[86] A timer 150 may interface the pum ps 145 or 147 to lim it the operational time thereof.

[87] The solar panel 149 may replenish the battery 144.

[88] In em bodiments, the raised entrance 121 may expose electrical contacts to which a n existing battery system of the kayak 100 may be connected. [89] The foregoing description, for purposes of expla nation, used specific nomenclature to provide a thorough understanding of the invention. However, it will be apparent to one skil led in the art that specific details are not required in order to practi se the invention.
