Abstract:
In accordance with one embodiment a marsh duck hunting stool, comprised of unitary construction having no detachable members, provides a compact, lightweight, floatable structure, with simple functionality, primarily used in a duck marsh environment. The stool includes a horizontally oriented seat platform with a single, elongated, vertically oriented support member. The support member comprises two tubular members, one sliding within the other, providing a plurality of seat height settings. A foot and stake assembly is pivotally disposed on the bottom end of the sliding tubular member. The foot and stake assembly limits soft soil penetration and provides fore and aft/side to side stability. The sliding tube rotates within the foot and stake assembly thereby providing 360 degree pivot of the seat platform.

     Marsh duck hunting is an extremely difficult and strenuous activity. Marsh duck hunters, usually burdened with heavy clothing, boots, and gloves, will wade to their chosen stationary location to hunt in a flooded marsh having water depths of 6″ to 35″. This flooded marsh will have a soft muddy, uneven underwater ground surface making it difficult to wade while maintaining balance. This flooded marsh includes vegetation having numerous forms such as trees, bushes and grasses often with underwater limbs and roots. Marsh duck hunters must also transport essential equipment such as gun, decoys and a device for sitting when wading to their chosen location. Upon arrival at the chosen location they will deploy decoys and then seek rest and concealment. This activity is often conducted during the dark, pre-dawn hours. 
     Marsh duck hunters therefore need a stool to sit on for rest and concealment. The stool needs to be compact and lightweight so it is easy to transport. When seeking concealment marsh duck hunters will utilize available vegetation where they will frequently encounter an underwater root system. The stool will therefore need to have a combination foot and stake system capable of penetrating this root system so the foot and stake can be embedded in the ground. When embedded, the foot and stake needs to provide stability with limited ground surface penetration of the stake. A stable stool will assist marsh duck hunters with maintaining their balance while sitting. Limiting ground surface penetration will maintain a constant seat height. The entire embodiment of the stool needs to be of a simple, single assembly having all non-detachable members. As such, marsh duck hunters will not have to contend with folding/unfolding or assembly/disassembly of the members nor will they have to contend with dropping and losing members in the water. The stool needs to be reliable thus it needs to be simple in functionality and strong in construction. The stool needs to have a pivotally mounted seat platform that allows marsh duck hunters to track their prey while remaining concealed with the lowest possible profile. The height of the seat from the ground needs to be adjustable to accommodate various water depths. Marsh duck hunters are constantly on guard to prevent dropping of their equipment in the water and thus loosing it. Therefore, the entire single stool assembly needs to float. 
     Single support post, pedestal type stools have been developed in the past for use in various outdoor activities. Some of the related prior art is designed for portability including features described as foldable, assembly/disassembly and collapsibility. These features have advantages for use on dry land but they become disadvantageous for use in a duck marsh. Following is a discussion of this prior art:

Inner pipe (1a) can become detached from outer pipe (1a). 
     Some of the related prior art claims suitability for use by the “duck hunter” as generally described, and in generally described conditions such as marsh, mud, muddy, sand, swamp, swampy, wetland, shallow, submerged, wet, damp, or soft. With consideration of the previous specific descriptions of the marsh duck hunter and the duck marsh, this prior art continues to include disadvantageous features and fails to include a totality of advantageous features for the activity of marsh duck hunting. A discussion of this prior art is as follows: 
     U.S. Pat. No. 6,893,097 Outdoor Stool System—The stake (52) and associated pivoting flared feet members (54, 56) is designed primarily for firm flat ground. The stool design comprising locking collar, pivoting feet, and necessary strength of support members, with no mention of the use of lightweight materials, indicates stool is made of metal thus heavy and sinkable. Stool comprises of detachable seat shaft (42) and locking collar (30). The “friction” engagement of seat shaft (42) by upper collar (30) could allow slippage of seat shaft (42). The pivotally mounted or fixed mounted seat (40) is a single center point design on bottom side of seat which creates a high wear, unstable joint. 
     U.S. Pat. No. 2,634,795 Swivel Seat—Since the basic design description makes reference to threads, collars, pins, and recesses this seat is deemed to made from metal thus heavy and sinkable. The seat has detachable members described as follows: a. there is no provision to retain post (20) if cotter key (32) is removed thus post (20) can slide out and become detached from upright (10) b. there is no provision to retain collar (22) if post (20) becomes detached from upright (10) and screw (26) becomes loose, c. there is no provision to retain anchor (38, 40, 42) if cotter pin (48) is removed thus this anchor can slide off and become detached from upright (10), d. cotter pins (32, 48) have no provisions to retain them when they are removed from their slots. The hold force between set screw (26) and the side wall of post (20) can loosen from dynamic vertical and horizontal (rotational) forces. The pivotally mounted seat (14) is a single center point design on bottom side of seat which creates a high wear, unstable joint. The narrow, pointed lower end of upright (10) will move easily side to side in soft soil conditions. 
     U.S. Pat. No. 5,673,966 Duck Hunters Toole Seat—The seat (1), retaining pin (7), and disc (6) are all detachable members. The seat is made primarily of metal thus heavy and sinkable. The pivotally mounted seat (1) is a single center point design on bottom side of seat which creates a high wear, unstable joint. The lower disc (6) is adjustable to limit the spear (6) penetration of variable ground surface densities but the seat height is fixed since support tube (3) is of a fixed length. The narrow, pointed lower end of support tube (3) will move easily side to side in soft soil conditions. 
     U.S. Pat. No. 2,720,249 Vertically Adjustable Pedestal Supported Revolving Stool—This stool has multiple detachable members for means of disassembly/assembly for transport/use respectively. Pedestal (3) is detachable and sinkable. Anchoring post (5) and base (2) have no retention provisions when set screws (23, 14) are removed thus they can become detached and need reassembly. Set screws (23, 14) have no retention system when they are removed. The seat height is fixed since the pedestal (3) is of a fixed length. The pivotally mounted seat (1) is a single center point design on bottom side of seat which creates a high wear, unstable joint. The large base (2) is best suit able for flat surfaces. The narrow, pointed anchoring post (5) will move easily side to side in soft soil conditions. 
     U.S. Pat. No. 5,975,635A Portable Pedestal Seat—This seat has no foot to limit ground surface penetration thus constant adjustment of the stake (ref tube 16) length would be necessary since the seat would continue to sink from the weight and motion of the occupant. Sliding tube (16) is detachable. The entire seat is made of “structural plastic”. Structural plastic durable enough for duck marsh duty is sinkable. The seat (11) is rigidly affixed to pedestal (14). Alignment of seat height adjustment holes in large tube (15) and small tube (16) are by sight and feel. 
     U.S. Pat. No. 6,035,572 Combination Gun Rest, Stool, Walking Stick—This is a combination stool, walking stick. By its own description this stool is designed for use at “waters edge”. The support and foot members of this stool are constructed of PVC having “suitable physical and mechanical properties”. PVC with “suitable physical and mechanical properties” strong enough for duck marsh duty will sink. The pivotally mounted seat (1) is a single center point design on bottom side of seat which creates a high wear, unstable joint. The stool has multiple detachable members that need to be assembled and disassembled. The narrow, pointed lower end of upright (33) will move easily side to side in soft soil conditions. The seat (35) attachment to upright member (33) is fixed with means for removal and storage for transport. 
     U.S. Pat. No. 5,470,038 Self Stabilizing Seat Support—This seat base (12) attachment to main shaft (11) is rigidly fixed. The seat height is fixed since main shaft (11) is of a fixed length. The folding seat and folding foot designs are deemed to be made of a durable, rigid material such as metal or high strength plastic due to their complex functionally. Metal or high strength plastic durable enough for duck marsh duty is sinkable. The narrow pointed stabilizer shaft (10) will move easily side to side. The wide spreading stabilizer foot (30) is for use on flat, smooth surfaces. 
     U.S. Pat. No. 401,302 Hunter&#39;s Portable Stool—Seat (A) attachment to support (C) is fixed. The seat height is fixed since support (C) is of a fixed length. The narrow, pointed stake at the lower end of support (C) will move easily side to side in soft soil conditions. Wood seat with back support and metal post assembly is large and heavy. 
     Some NPL has been found on related prior art that is commercially available. Considering many design details are omitted from the pertinent available literature whereby further disadvantages could possibly be cited and with consideration of the previous specific descriptions of the marsh duck hunter and the duck marsh, this prior art can still be shown to include disadvantageous features and fail to include a totality of advantageous features for the activity of marsh duck hunting. A discussion of this prior art is as follows: 
     Dick&#39;s Web Site Advertising “Avery Marsh Seat”: The support post and lower supports are aluminum which will make the entire seat sinkable. Seat is rigidly affixed to the support post with a folding mechanism. The supports are foldable but too wide for effective use in a vegetative under growth of a duck marsh. The narrow, pointed stake on the lower end of the support will move easily side to side, fore and aft in soft soil conditions. 
     Big Supply Shop Web Site Advertising “MOJO Mud Seat”: The stake and associated pivoting flared feet members are designed primarily for flat ground and would not be effective in the vegetative undergrowth of the duck marsh. The stool is made of steel thus heavy and sinkable. Seat is rigidly affixed to the top of the shaft. 
     Cabela&#39;s Web Site Advertising “Cabela&#39;s Northern Flight Marsh Chair”: The support post and lower supports are aluminum which will make the entire seat sinkable. Seat is rigidly affixed to the support post and includes a folding mechanism. The supports are foldable and too wide for effective use in a vegetative under growth of a duck marsh.

     DETAILED DESCRIPTION 
     First Embodiment—FIGS.  1 - 24   
       FIG. 1  to  FIG. 10   
     Made from floatable material, comprising a predetermined cross-sectional shape, a seat  2  is horizontally disposed. A seat cushion  1  is permanently glued to the topside of seat  2 . Made from floatable material, comprising an elongated, hollow, predetermined cross-sectional shape ( FIGS. 7, 8 ), an upper end of a seat base  4  is rigidly attached, at a right angle, to the underside of Seat  2 . Made from floatable material, a gusset  3  is rigidly attached to opposite sides of seat base  4  and the underside of seat  2 , thereby providing additional strength to the attachment of seat  2  to seat base  4 . 
     Made from floatable material, comprising a predetermined cross-sectional shape, an end cap  5  is attached to the lower end of seat base  4 , thereby providing additional strength to the lower end of seat base  4 . 
     Made from floatable material, comprising a predetermined cross-sectional shape, a foot  6  is horizontally disposed. Providing stability and resistance to soft ground penetration, foot  6  is pivotally attached to the lower end of a sliding tube  12  ( FIG. 2 ). 
     Made from floatable material, with center points in alignment, a stake base  7  comprising a predetermined cross-sectional shape, is rigidly attached to the under side of foot  6 . Made from floatable material, a top stake  8  and a bottom stake  9  interlock, thereby providing mutual lateral strength ( FIG. 11 ). Comprising a wide, blunt profile, top stakes  8  and bottom stake  9  are rigidly attached to the underside of stake base  7 . 
     Made from round schedule 40 PVC pipe, a stationary tube  11  is disposed inside the full length hollow center of seat base  4  ( FIG. 3 ). Surrounding stationary tube  11 , a through hole at the center point of end cap  5  ( FIG. 3 ) disposes stationary tube  11  on the lateral center point of seat base  4 . Sufficient in length, a lower portion of stationary tube  11  extends through end cap  5  exposing a lower through hole in stationary tube  11 . 
     Made from round schedule 40 PVC pipe, sliding tube  12  is slidably disposed inside stationary tube  11 . Comprising a failsafe connection, a wire lock pin  10  is disposed in the lower through hole of stationary tube  11  and one of a plurality of longitudinally aligned through holes in sliding tube  12 . 
     Made from round schedule 40 PVC pipe, a retainer tube  14  comprises a through hole on one end ( FIG. 10 ) and a through slot beginning on the same end and in perpendicularity to the through-hole ( FIG. 9 ). Length of the through slot is less than the overall length of retainer tube  14  ( FIG. 9 ). A sparer tube  15  comprises a through hole. With the through hole in spacer tube  15  in alignment with the upper through hole in retainer tube  14 , spacer tube  15  is disposed inside the through slot of retainer tube  14  ( FIG. 9, 10 ). A stationary pin  13  is disposed within the alignment of an upper through of stationary tube  11 , and the though hole in spacer tube  15 , and the through hole in retainer tube  14 , thus disposing retainer tube  14  inside stationary tube  11 . Stationary pin  13  is longer than the diameter of stationary tube  11  thereby extending on each side of stationary tube  11 . The bottom side of seat  2  comprises a flat-bottom hole and slot at the center point ( FIG. 4, 5, 6 ). The top face of stationary tube  11  is disposed on the bottom of the flat bottom hole. The additional length of stationary pin  13  on each side of stationary tube  11  is disposed on the bottom of the pin slot ( FIG. 5 ). The opposite side of stationary tube  13  is flush with the bottom of seat  2  ( FIG. 5 ). Theretofore, attaching seat  2  to seat base  4  ( FIGS. 7, 8 ) disposes stationary tube  11  and retainer tube  14  with spacer tube  15 , as an assembly, within the embodiment. 
     
       FIGS. 11 to 22 
     
     Sliding tube  12  comprises an upper through hole and a lower through hole in longitudinal alignment, perpendicular to the longitudinally aligned plurality of through holes ( FIG. 12 ). A Sliding pin  20  is disposed in the upper through hole of sliding tube  12 . Both ends of sliding pin  20  are hammer forged flush with the outside surface of sliding tube  12 , thereby permanently affixing sliding pin  20  in the upper through hole in sliding tube  12 , and thereby preventing interference with the inside wall of stationary tube  11  (see  FIGS. 12, 13 ). With sliding tube  12  fully retracted inside stationary tube  11 , a lateral slot in the upper end of sliding tube  12  encompasses stationary pin  13  ( FIG. 12 ). 
     Sliding pin  20  is slidably disposed inside the through slot in retainer tube  14 , thus disposing retainer tube  14  inside sliding tube  12 . When sliding tube  12  slides to the bottom of stationary tube  11  and wire lock pin  10  is not installed, sliding pin  20  will contact the bottom end of the through slot in retainer tube  14  thereby preventing sliding tube  12  from sliding out of stationary tube  11 . Assuring free movement of pin  20 , spacer tube  15  maintains sufficient width of the through slot in retainer tube  14 . The through slot in retainer tube  14 , in perpendicular alignment with the lower through hole in stationary tube  11 , and encompassing sliding pin  20 , maintains longitudinal alignment of the plurality of through-holes in sliding tube  12  and the lower through hole of stationary tube  11 , thereby providing quick and easy insertion and removal of wire locking pin  10 . 
     Sufficient is size to surround the outside diameter of sliding tube  12  ( FIGS. 17, 18, 19 ), foot  6  comprises a through hole perpendicular to the top side and the underside. The through hole in foot  6  is countersunk on the underside ( FIG. 18 ). A retention washer  16  has a center hole diameter equal to the through hole diameter in foot  6 . With an outside diameter equal to the diameter of the countersunk hole, retention washer  16  is press fit into the bottom of the countersunk hole in foot  6  ( FIG. 18, 19 ). With the bottom end of sliding tube  12  extending through the through hole of foot  6 , a rotating pin  19  is disposed in the lower through hole in sliding tube  12  ( FIG. 12 ). Comprising a length longer than the diameter of sliding tube  12  and disposed inside the countersunk hole on the bottom of foot  6 , rotating pin  19  retains foot  6  on the lower end of sliding tube  12 . Retention washer  16  provides wear protection between rotating pin  19  and bottom of countersunk hole in foot  6 . 
     Sufficient in size to surround the outside diameter of sliding tube  12 , the top side of stake base  7  comprises a flat bottom hole ( FIG. 21 ). The flat bottom hole in stake base  7  comprises a slot in the bottom. A stationary washer  18  comprises a round bar member welded to its underside ( FIGS. 14, 15, 16 ). Stationary washer  18  is disposed on the bottom of flat bottom hole in stake base  7  with the round bar disposed in the slot thereby preventing stationary washer  18  from rotating ( FIG. 21,22 ). The bottom face of stationary tube  12  is pivotally disposed on top of stationary washer  18 . Heretofore, stationary washer  18  provides vertical load support for sliding tube  12  and protects the bottom of the flat bottom hole in stake base  7  from wear. Sandwiched between stationary washer  18  and the bottom face of sliding tube  12 , a rotating washer  17  provides a rotational bearing surface for the bottom face of sliding tube  12 . 
     The under side of Stake base  7  comprises a slot, in perpendicular alignment with at slot. Disposed in the slots on the bottom of stake base  7 , top stakes  8  and bottom stake  9  are attached to stake base  7 . Comprising a pivotally mounted, non detachable assembly, stake base  7 , with top stake  8  and bottom stake  9 , is attached on center point to the bottom side of foot  6 , heretofore encompassing stationary washer  18 , rotating washer  17 , the lower end of slider tube  12 , rotating pin  19  and retention washer  16 . 
     
       FIGS. 23 and 24 
     
     A strap  21  comprises of a lower section and an upper section. A D-Ring is permanently attached to one end of the upper section of strap  21  and the opposite end is permanently attached to a strap adjuster  23 . A D-Ring is permanently attached to one end of the lower section of strap  21  and the opposite end is slidably attached to strap adjuster  23 . A screw eye  24  is permanently attached to gusset  3 . D-Ring  21  attached to the upper section of strap  21  is permanently attached to screw eye  24 . D-Ring attached to the lower section of strap  21  is permanently attached to wire lock pin  10  thereby securing wire lock pin  10  to the embodiment. 
     Operation 
     Having sliding tube  12  locked in the fully retracted position inside stationary tube  11 , the marsh duck hunting seat is typically carried with strap  21  adjusted to the preferred length. The top end of strap  21  is permanently attached to gusset  3 . The bottom end of strap  21  is permanently attached to wire lock pin  10 . 
     Seat  2  is rigidly attached, at a right angle, to the top of seat base  4 . Gusset  3  rigidly attaches to opposite top sides of seat base  4  and adjacent bottom sides of seat  2 . Stationary tube  11  is rigidly attached inside seat base  4 . Retainer tube  14  is rigidly attached inside stationary tube  11 , thus the stool needs no assembly/disassembly or folding/unfolding. 
     The seat and all rigidly attached members as heretofore described is adjusted to the desired height by first unlocking and removing wire lock pin  10  from the aligned through holes in stationary tube  11  and sliding tube  12 . Wire lock pin  10  is secured to the bottom end of strap  12 , thereby eliminating the fear of loss when removed from the through holes. Sliding tube  12  is then moved to a chosen position. The wire lock pin  10  is then re-inserted and locked in the aligned through holes thereby providing a failsafe connection between stationary tube  11  and sliding tube  12 . Because sliding pin  20  in sliding tube  12  slides longitudinally inside the through slot in retainer tube  14 , the chosen through hole in sliding tube  12  stays in alignment with the lower through hole in stationary tube  11  thereby providing quick and easy seat height adjustment. 
     If sliding tube  12  slides to its full extension without the wire lock pin  10  inserted in the aligned through holes in stationary tube  11  and sliding tube  12 , then sliding pin  20  will encounter the bottom of the through slot in retainer tube  14  and thus prevent sliding tube  12  from sliding out of stationary tube  11 . 
     The slot in the top end of sliding tube  20 , encompassing stationary pin  13  when sliding tube  12  is fully retracted inside stationary tube  11 , prevents sliding tube  12  from rotating inside stationary tube  11  if seat  2  is pivoted without the wire lock pin  10  inserted in the aligned through holes of stationary tube  12  and sliding tube  11 , thus preventing twisting and damaging retainer tube  14 . 
     Foot  6 , stake base  7 , top stake  8  and bottom stake  9  comprise a rigid assembly pivotally attached to the lower end of sliding tube  12 . The rigid assembly as heretofore described encompasses a rotating pin  19  disposed in the lower through slot of sliding tube  12  thus retaining the assembly on the bottom end of sliding tube  12 . 
     The rigid assembly of foot  6 , stake base  7 , top stake  8  and bottom stake  9 , as heretofore described, encompasses a stationary washer  18  and rotating washer  17  onto which vertical, pivotal, loading from sliding tube  12  is urged. 
     Top stake  8  and bottom stake  9  are positioned into the ground. The wide, blunt profile of top stake  8  and bottom stake  9  in combination with foot  6 , limits their penetration depth in soft ground thereby eliminating the need for further seat height adjustments. The wide profile of stake base  7  and top stake  8  and bottom stake  9  in combination with foot  6  provide side to side, fore and aft stability. 
     The flat side profile of top stake  8  and bottom stake  9  provide rotational resistance when embedded in soft ground thereby allowing proper functionality of the seat pivoting mechanism encompassed in the heretofore described pivotally disposed foot  6 , stake base  7 , top stake  8 , and bottom stake  9  assembly. 
     After use, top stake  8  and bottom stake  9  are removed from the ground. The wire locking pin ( 10 ) is unlocked and removed from the aligned through holes in stationary tube  11  and sliding tube  12 . Sliding tube  12  is fully retracted to its shortest position. Wire locking pin ( 10 ) is re-inserted and locked in the aligned through holes. 
     The marsh duck hunting seat is thereby ready for transport. 
     Conclusion, Ramifications, Scope 
     Thus the reader will see that at least on embodiment of the marsh duck hunting stool provides more advantages and fewer disadvantages to the marsh duck hunter as follows: 
     Comprising construction using predetermined proportions of floatable material, schedule 40 PVC pipe, metal, and nylon members, the marsh duck hunter stool will float, thereby reducing the fear of loss. 
     Comprising lightweight (less than 5 lbs.) and compact size (less than 22″ shortest length, the marsh duck hunter stool is easier to transport. 
     Comprising unitary construction with non detachable members, the marsh duck hunting stool is easier to use since no assembly/disassembly or folding/unfolding is needed. 
     Comprising unitary construction, fear of loss of any member is eliminated. 
     Comprising a pivotally attached lower foot and stake base, the seat will pivot 360 degrees allowing easier tracking of birds in flight 
     Comprising a pivotally attached lower foot and stake base, the seat attachment to the seat base can be rigid and reinforced, thereby providing more strength and durability at this high stress point. 
     Comprising a blunt shape and in combination with a flat foot, the stakes provide greater resistance to ground penetration thereby eliminating the need to re adjust seat height. 
     Comprising a wider profile, the stakes and stake base provide better side to side, fore and aft stability. 
     Comprising tapered bottom ends the stakes facilitate easier penetration of the underwater vegetative conditions in the duck marsh. 
     Comprising a sliding, vertically disposed tube inside a vertically disposed stationary tube, the seat height can be adjusted to accommodate various water depths. 
     Comprising self alignment of the longitudinally disposed seat height adjustment holes, the seat height is easier and quicker to set. 
     While the above description contains many specificities, these should not be construed as limitations on the scope, but rather as an exemplification of one embodiment thereof. Many other variations are possible. For example, the width and length of seat and seat base can vary, the seat base can be made from a single piece, the seat height can be taller or shorter, the foot size can vary, and the stake base size can vary. Furthermore, the embodiment title of “marsh duck hunting stool” should not be construed as limiting in scope, but rather as an exemplification of one embodiment thereof. For example, other possible uses would be, but not limited to, for fishing or field hunting. 
     Accordingly, the scope should be determined not by the embodiment illustrated, but by the appended claims and their legal equivalents.
