DETAILED DESCRIPTION
[0020] FIG. 1 shows a cooker assembly 10 in accordance with the present invention, mounted to the gunwale 12 of an exemplary pleasure boat 14 or similar vessel so as to be suspended outboard of the vessel and over the surrounding water 16. As can also be seen with reference to FIGS. 2-3, the cooker assembly 10 includes two principle subassemblies, namely, a steamer/boiler assembly 20 in which the food is cooked and a support arm assembly 22 that suspends the steamer/boiler assembly outboard from the vessel.
[0021] As can be seen more clearly in FIGS. 2-4, the steamer/boiler assembly 20 includes a pot member 24 that holds a removable strainer basket 26 and that is closed by a lid 28 having a handle 30. A steam rack 27 may also be included, that rests on the bottom of the main pot 24 as shown in FIG. 4, to support the strainer basket above the level of the water in the pot. With just these basic components, the pot member somewhat resembles a conventional cooker pot with a strainer insert, and may suitably be constructed of aluminum, stainless steel or other suitable durable, heat resistant material. In the present invention, however, the closed lower end portion of the pot member 24 is integrally combined with a burner section 32 that provides a heat source for boiling water in the pot member and cooking the contents. The burner section includes a heating element 34 that in the illustrated embodiment is a propane-fueled burner, but in other embodiments may be burners using other forms of fuel such as white gas or diesel, or electric heating elements such as resistance heating coils or induction heating elements, for example.
[0022] As can be seen with further reference to FIGS. 2-4, burner 34 is enclosed within a depending shell 36, suitably cylindrical in shape that includes a series of vent openings 38 that admit combustion air, and a wind guard 40 that is slideable in an annular track using a knob 42 so as to selectively block or open the vent openings depending on wind direction and force. The burner section is welded or otherwise connected to the bottom of the steamer/boiler pot at a burner seat 44, so that the burner section and pot are joined together as an integrated structure, with a vent space 46 being provided at the top of the burner seat to allow combustion gasses to escape outwardly and upwardly about the perimeter of the pot.
[0023] A drain cock 48 is also mounted at the base of pot 24, to allow water/liquid to be drained and rinsed out when desired. The drain cock is preferably located towards the outboard side of the pot, so that when the pot is suspended over the side as shown in FIG. 1 the drain cock will discharge directly into the water and well away from the side of the boat.
[0024] Propane (LP gas) or other combustible fuel is supplied to the burner section through a flexible fuel line 50, from a main supply line 52 that is connected to a tank 54 (see FIG. 1) or other onboard source and routed through a regulator 56. The end of fuel line 50 that is in turn connected to the burner is shielded from heat/flame by a metal plate 58. In addition, an electric igniter 59 may optionally be included. In the case of embodiments using electric heating elements rather than gas, an electrical cord may be employed to supply current from a suitable source, such as an onboard generator or an inverter operating on batteries, for example.
[0025] As can be seen, the entire steamer/boiler assembly 20, including the burner section is supported from the arm assembly 22 by a gimble mechanism 60. The gimble mechanism includes a generally horizontal pivot arm 62 having a forked, semicircular yoke 64 at its outer end that extends around the upper end of pot 24. End portions of the yoke are joined to opposite sides of the pot by coaxial pivot connections 66, aligned 180° to the axis of the pivot arm and generally parallel to the gunwale of the boat (when the assembly is mounted and swung out as seen in FIGS. 1-4). As can be seen with further reference to FIGS. 2 and 4, pivot connections 66 are preferably located relatively close to the top of the steamer/boiler pot (i.e., above midlevel) so that the majority of the combined weight of the pot, whether empty or filled, and the burner section, will be located below the pivot connections and therefore act as ballast to maintain the assembly stable and upright within gimble mechanism 60.
[0026] As can be seen in FIG. 3 and also FIGS. 5-6, the base end of pivot arm 62 includes an axial shaft 68 that extends, in a direction generally opposite yoke bracket 64. As will be described in greater detail below, shaft 68 connects to support assembly 22 in a manner that provides a second pivot axis, perpendicular to that formed between yoke 64 and pot 24 by pivot connections 66. A slotted plate 70 extends downwardly from the junction between arm 62 and shaft 68, generally perpendicular to the axis of the latter. As shown in FIG. 4, the lower extent of the yoke bracket is preferably formed as an outwardly tapering flange 72, that is joined to the lower portion of pivot plate 70 by lower flange 74 of arm 62, to help support and transfer the weight of the cooker assembly into the into support assembly 22.
[0027] Referring again to FIGS. 3 and 4, the base shaft 68 of pivot arm 62 is inserted through a cooperating horizontal bore 76, formed in an upright stanchion 80 of the support assembly 22. A wing nut 82 is installed on the threaded end 84 of shaft 68 to join the arm 62 to the stanchion in pivoting relationship. Low friction washers 86, suitably formed of Teflon, nylon, UHMWPE or a similar plastic material, are installed on the shaft to form bearing interfaces between the stanchion and the nut on one side and the pivot plate 70 on the other. The arm and the pot assemblies are thus able to pivot about the horizontal axis defined by pivot shaft 68, in a fore-and-aft direction relative to the vessel as shown in FIG. 1, with selective tightening of the wing nut serving to dampen the motion as designed; the second horizontal axis formed by pivot connections 66 in turn enables the pot assembly to swing in-and-out in an athwart-ships direction.
[0028] Consequently, the pot assembly, ballasted as described above, maintains a more-or-less upright orientation to avoid spillage despite pitching and rolling of the boat or other vessel. The extent of pivoting in-and-out swing in motion, in a direction perpendicular to the gunwale in FIG. 1 may be limited to a designed maximum by contact between the steamer/boiler pot and the gimble yoke. Pivoting motion in a fore-and-aft direction, parallel to the gunwale, may in turn be limited by cooperation of an arcuate slot 88 in a lower part of pivot plate 70 and a stop pin 90 that is installed in stanchion 80 below and parallel to pivot shaft 68. As can be seen in FIG. 6B, the stop pin 90 is sized to be received in the arcuate channel of the pivot shaft, the channel including first and second end points 92a, 92b, such that the pivot arm and plate will thus pivot freely in each direction until the ends 92a, 92b of the channel coming up against the stationary limit pin 90. As can be seen in FIGS. 2 and 6A, the limit pin 90 is secured in the upright stanchion 84 of the support assembly, by a nut 94 that is installed on a threaded end 96 of the pin opposite that which is received in the channel 78 of the pivot plate. The permitted range of motion may vary depending on design factors, but in the illustrated embodiment may suitably be about 30° total, i.e., 15° fore-and-aft of vertical. A low-friction washer 98 is installed between plate 70 and the side of the stanchion to facilitate the pivoting movement of the former.
[0029] As can be seen with further reference to FIGS. 4 and 6A-6B, the pivot arm of the support assembly is suitably constructed of a series of rigid tubular members mounted in end-to-end relationship, suitably formed of aluminum, stainless steel, fiberglass or molded plastic pipe, for example. Upper and lower relatively elongate, straight members 100, 102 form a vertical stanchion portion of the support arm, with the arm 62 of the gimble mechanism being mounted to the upper member in the manner described above. The lower end of the upper tubular member 100 is necked down to form a reduced-diameter neck portion 106 (see FIG. 4), that in turn is received in the upper end of the lower tubular member 102 to form a vertical-axis sleeve-and-socket connection 108 that permits the upper member 100 to rotate relative to the lower member 102. A spring-loaded locking button 110 projects from the stepped-down neck of the upper tubular member, through a cooperating opening 112 in the lower member 102 so as to lock the members against relative rotation. Depressing button 110 releases the locking mechanism, thereby allowing the gimble mechanism and pot assembly to be pivoted inboard for access at the gunwale, e.g., to load/unload basket 26. Depressing button 110 also allows the upper member 100 to be withdrawn from the lower member, for disassembly and stowage when desired.
[0030] A cap 114 closes the top of the upper tubular member 100, and a lanyard connects the lid 30 of the pot assembly to the upper end of the stanchion to the lid 30 of the pot assembly to prevent losing the lid overboard. In addition, a lamp unit 118 (e.g., an LED light unit) may be mounted to the upper end of the stanchion for purposes of illuminating the lid and the contents of the pot during dark.
[0031] A spring stopper 120 is mounted in the lower stanchion member 102 so as to extend outwardly towards the pot assembly, on a shaft 122 that is secured in the member by a nut 124 shaft. The bottom of the lower stanchion member is in turn mounted to a first 90° elbow 126 that bends downwardly and inwardly to a horizontal leg that extends towards the gunwale of the boat, and that is mounted at a sleeve-and-socket joint 128 to a second 90° elbow 130, joint 128 being secured by a spring-loaded button catch 132 similar to that described above. The second 90° elbow 130 extends horizontally and then back down vertically, the vertical leg being mounted to a base 134 that is in turn rotatably supported on a mounting plate 133. The mounting plate may be mounted directly to the gunwale, or, as is shown in FIGS. 6A-6B and also FIG. 2, it may be mounted to an adaptor 135 having a bore 136 that fits over and detachably engages a downrigger-type fishing rod holder, sometimes referred to colloquially a “rocket launcher,” of a generally conventional type that is commonly fitted to recreational boats; as can be seen, the bore 136 may be angled off vertical (e.g., by 5-30°) so as to correspond to the angle of the rod holder over which it fits.
[0032] The support assembly 22 may therefore be assembled and disassembled by joining/disconnecting the tubular segments and other components described above. The pieces of the support assembly are preferably sized so that when disassembled they will all fit within the interior of the strainer basket 26, which is in turn housed within the outer pot 24, thus providing compact, space efficient storage of the apparatus. Moreover, the entire pot assembly, with the components of the support assembly stowed therein, may be sized to fit within a standard 5 gallon bucket having a snap lid, both for purposes of shipping and marketing and also to provide the boat owner with a container that not only stores the system but that is also useful as an implement in and of itself.
[0033] It will be understood that the scope of the appended claims should not be limited by particular embodiments set forth herein, but should be construed in a manner consistent with the specification as a whole.
