Abstract:
An improved fishing or hunting wader, exposure suit or foul weather pants/bib incorporates a novel waterproof connectable hatch to provide access for urination. The low profile and lightweight waterproof hatch is centered over the groin area and allows the wearer of a fishing wader, or similar foul weather gear pants, to be able to quickly open the hatch and urinate without removing the cumbersome garment. A hinged or connectable lid may swing upwards and downwards and features a hook-and-loop fastener, a magnetic, or mechanical fastener so that the lid is held up in place and out of the way. After urination, the lid may conveniently snap back into place against a seal or O-ring thereby forming a water tight seal.

CROSS REFERENCE TO RELATED APPLICATIONS 
     This non-provisional application claims priority to provisional patent application 61/766,089 filed on Feb. 18, 2013, the contents of which are fully incorporated herein with this reference. 
    
    
     FIELD OF THE INVENTION 
     The present invention generally relates to fishing waders. More particularly, the present invention relates to a water-tight urination relief hatch for fishing waders, foul weather gear, or aquatic sports wear. 
     BACKGROUND OF THE INVENTION 
     Waist and chest waders are commonly used worldwide by both fly fishermen, spin fishermen, hunters and the like. Modern waders typically have built-in feet and in many cases, these are built-in stocking feet or neoprene-type feet or boots. Similar equipment is worn by crab fishermen or other mariners in foul weather situations wherein chest-type rain pants with suspenders are used with a jacket over the top. In a fly or spin fishing application, a fishing vest is normally worn over the wader suspenders and also a foul weather jacket may be placed over top. For example, when a fisherman is in Alaska, it is not unusual for the fisherman to have on a pair of undergarments, such as jeans over a fleece, the chest waders and suspenders, a fly fishing vest, a rain proof over jacket, a wading safety belt, and another belt containing either a canister of pepper spray or a pistol for protection against bears and other wildlife. 
     For both fishing and foul weather gear applications, the wader or rain protection garment may be worn for many hours or even an entire day. Hunting waders are also very popular. Hunting waders come in a variety of camouflage patterns and accommodate the hunter who is wading through bogs or tundra or even lakes (for example—duck hunters). Another name for these systems is “Waders With Bibs.” One is referred to any search engine of the internet where one can enter the search term “waders” and see the wide variety that is available. Fishing wader manufacturers include Cabela&#39;s®, Orvis®, Simms®, Redbull®, Hodgman® and many others. Waders can either be simple waders or rain protection suits. Pants or chest high waders can be rubber or of modern high technical fabrics that breathe, such as Gore-tex®. 
     Taking the waders and all of this equipment off to urinate is a real hassle. Not only is it inconvenient, but in a driving rain storm, one can get very wet during the process. For an Alaska fly fisherman, taking off and laying down your fly fishing vest and jacket often results in it being laid along the muddy banks of a river or worse. Furthermore, taking off all of the gear could temporarily leave a fisherman or hunter without access to a firearm or bear spray if the need to defend themselves from wildlife occurred at that same moment. Even if this unfortunate situation never happens, it is still quite disconcerting to the fisherman or hunter every time they need to remove their gear and put themselves in greater harm. 
     Dehydration is another important issue which can happen to a fly fisherman or hunter. With the advent of modern breathable waders, it is now possible to hike for many miles wearing your waders. In July and August of 2012, the inventors of this patent application extensively fished Southeast Alaska&#39;s rivers and streams. The inventors found there is a tendency to drink very little water because it is so much of a hassle to remove all of the gear and the waders to urinate. Leg cramps and other symptoms due to dehydration became apparent on many occasions. This is simply an unhealthy situation. What is needed is to allow a fisherman or hunter wearing a wader to drink as much as they would like and still be able to relieve themselves in a quick and efficient manner. 
     Many have already attempted to address such issues and concerns, yet were either unsuccessful or unable to bring their inventions to market. Orvis&#39;s® U.S. Pat. No. 7,770,235 describes a typical modern fishing wader consisting of a lightweight nylon-faced laminate material utilizing tape or sonic welds to achieve a durable, lightweight and comfortable wader. The &#39;235 patent has no provision to facilitate urination. However, a number of rubber clothing or wader patents do disclose features for urination. For example, U.S. Pat. No. 291,854 to Platt shows a strapped opening in the front of the wader with folds to prevent water entry. This is, of course, a very crude and cumbersome approach compared to the present invention. 
     U.S. Pat. No. 2,385,816 illustrates a waterproof sealing closure zipper, which again, is very difficult and cumbersome to use and also, is not completely waterproof during long-term immersion, for example, in a river or a lake. 
     U.S. Pat. No. 2,570,019 illustrates a protrusion with a drawstring to facilitate urination. This has a number of obvious disadvantages. Not only is it aesthetically unacceptable, it would also tend to be very messy. 
     U.S. Pat. No. 2,746,113 illustrates yet another type of waterproof zipper, which again, is not completely waterproof during long-term immersion. 
     U.S. Pat. No. 2,853,758 shows a method of rolling the fabric tightly and then clamping it down to attempt a waterproof seal. This also has a lacing structure over it. Of course, all of this would be very cumbersome and probably no more efficient than simply removing the garment. 
     U.S. Pat. No. 4,274,159 illustrates a type of tube with a roll-up and a waterproof zipper. It is aesthetically unacceptable, messy and also cumbersome. 
     U.S. Pat. No. 4,601,085 illustrates a water resistant slide fastener which appears very cumbersome and difficult to use in practice. 
     U.S. Pat. No. 4,888,859 also illustrates a water tight slide fastener which appears to be not completely waterproof during long-term immersion. 
     U.S. Pat. No. 5,210,879 illustrates waders equipped with an opening and closing means to allow fisherman to urinate without having to draw the garment down. However, this opening is in the form of a tubular member, which must be coiled and then closed over with Velcro® to prevent ingress of water. Again, this is aesthetically not pleasing, messy and it is also dubious whether this would truly form a water tight seal. 
     U.S. Pat. No. 5,444,898 illustrates another type of water resistant closure, involving a slide fastening assembly and a pair of stringer tapes integrated with waterproof fabric. In the field, this would be difficult to use and very difficult to close back up again. 
     U.S. Pat. No. 6,105,214 illustrates a water resistant slide fastener with gripper elements positioned along the edges. Again, this looks like it would be very difficult to use and is of dubious quality during long-term immersion. 
     U.S. Pat. No. 6,223,349 illustrates a closure device for a slit opening of an aquatic sports suit. This is a type of zipper closure that may or may not be waterproof during total immersion. In any event, it would be difficult to use in the field and impractical for a chest wader. Most waders come up to well above the waist area. The drawing shown in FIG. 5 of the &#39;349 patent is really not practical. In other words, one is not going to be able to open up the zipper at the top of the garment analogous to a pair of Levis. This is because the wader typically goes up onto the chest where there may be one or more pockets for holding fly fishing boxes and the like. This is an essential problem with all of the zipper approaches in that there is really no way to open them in the traditional way at the top. This is because the garment goes a very long way above the groin area. Zipping the entire garment, from the chest all the way down to the groin then involves pockets, a safety belt and the suspenders which rapidly becomes very impractical. 
     U.S. Pat. No. 6,317,893 is a good illustration of a prior art wader with a safety belt  24  and suspenders  14 . This particular invention does not have provision for urination, but does illustrate the difficulty of removing the wader and pulling it down. Wader safety belt  24  is essential because if the person wearing the wader were to slip in a river or a lake, the wader legs would very quickly fill with water which could immediately add a lot of weight to the system and be life-threatening. Accordingly, one or more wader belts 24 or 18 are worn to prevent such water ingress into the system. Even if the water was not life-threatening, it would certainly wet the undergarments and make the wearer very wet and miserable for the remainder of the day. 
     U.S. Pat. No. 6,363,531 and U.S. Pat. No. 6,438,757 illustrate types of waterproof zippers. The &#39;757 patent shows a zipper that is designed with a flap enclosure at the top so that it would not have to be zipped all the way up the chest area. However, the next problem it ensues is one ends up with a very narrow slit, in terms of enough of an opening, to be able to conveniently urinate. 
     U.S. Pat. No. 6,389,598 illustrates a sealably accessible wader system. This particular invention attempts to create a wader material that forms an opening. A removably discrete and separate closure element is detachable from the wader. This creates problems in that the closure element must be placed on the ground during urination or held with one of the user&#39;s hands. This can become awkward and difficult to operate when in use. If the closure element is placed down on the ground it can become soiled and then later interfere with the watertight seal when reattached. There is no provision to attach the closure element to the wader where it does not interfere with the urination process. Furthermore, this particular invention does not disclose or teach how such a structure will be manufactured as the wader material is not a suitable material to be used to form a water tight hatch. Wader material is substantially flexible, malleable and flowing and does not hold its shape because it is not substantially rigid. The disclosure of the patent fails to enable one skilled in the art to actually practice the invention because its structures cannot be manufactured nor do the structures work in reality. 
     Accordingly, there is a need to provide a convenient access hatch in the wader or equivalent garment, which can be easily flipped open allowing the wearer to urinate without removing any of the other garments, belts or accessories. None of the prior art illustrates a sealed enclosure area with a hinged lid, which can be quickly opened. The present invention provides a hinged access cover which can be round, oval or of many shapes that when shut provides a high integrity waterproof seal. It is provided with a quick release snap so that it can be opened quite readily. The opening is sufficiently large to conveniently access undergarments and to be able to urinate, and the entire system does not feature tubes or tunnels, which could become messy during urination. In addition, the access cover is provided with a convenient attachment mechanism so that it can be put up out of the way during the process. It is readily closed by snapping it back into place and once again forming a waterproof seal for the wader or garment. The present invention fulfills the needs discussed above and provides other related advantages. 
     SUMMARY OF THE INVENTION 
     An exemplary embodiment of the present invention includes a waterproof pair of waders with a sealable opening for relief of bodily fluids within a pair of pants. The pair of pants comprises a first and second foot or boot portion joined respectively to a first and second leg portion. The first and second leg portions are joined to a torso portion terminating generally at or between a waist and a neck of a wearer. The pair of pants comprise a substantially waterproof material. A separately manufactured and substantially rigid base is sealed to the pair of pants disposed in a groin section of the pair of pants, wherein the base forms an aperture. A lid is pivotably attached to the base and configured to engage the aperture. A seal is disposed between the base and the lid forming a waterproof closure of the aperture when the lid is in a closed position. 
     Other exemplary embodiments may include the seal disposed on the base or the seal disposed on the lid. A manually releasable latch may be connected to the base and configured to retain the lid in the closed position. A compression latch may be connected to either the lid or base and configured to secure together the lid and base. The lid may comprise a grasping feature. A temporary attachment mechanism may be connected to the base or pair of pants and configured retain the lid in an open position. The temporary attachment mechanism may comprise a magnet, a hook-and-loop fastener or a second latch. The aperture may be circular, round, rectangular, or trapezoidal shaped. The seal may comprise a compressible seal. A cosmetic flap may be connected to the pair of pants covering the base and lid. The base may be comprised of a different material as compared to the substantially waterproof material of the pair of pants. 
     Another exemplary embodiment of the present invention includes a waterproof pants including a pair of pants comprising a first and second foot or boot portion joined respectively to a first and second leg portion. The first and second leg portions are joined to a torso portion terminating generally at or between a waist and a neck of a wearer. The pair of pants comprise a substantially waterproof material. A water-sealable opening is connected to the pair of pants disposed generally about a groin section. The water-sealable opening comprises a substantially rigid base sealed to the pair of pants forming an aperture, and a substantially rigid lid is pivotably connected to the base and configured to engage the aperture forming a waterproof seal therebetween. 
     Other exemplary embodiments may include a compressible seal disposed between the base and the lid. A latch mechanism may be attached between the base and the lid and configured to keep the lid in a closed position. The lid may comprise a grasping feature. A temporary attachment mechanism may be connected to the base or pair of pants and configured to retain the lid in an open position. The temporary attachment mechanism may comprise a magnet, a hook-and-loop fastener or an upper latch. A flap may be connected to the pair of pants covering the base and lid. 
     Another exemplary embodiment of the present invention includes a relief hatch retro-fit kit for a pair of waders or pants. A rigid base is sealable to the pair of pants and disposed in a groin section of the pair of pants. The base forms an aperture. A lid is connectable to the base and configured to engage the aperture. A cutting template is for marking on the pair of pants a cut path. 
     Other exemplary embodiments may include a seal disposed between the base and the lid forming a waterproof closure when the lid is in a closed position. The base may include a flange for sealing to the pair of pants. An adhesive may be used for creating a waterproof bond between the flange and the pair of pants. A backing plate may be configured to fasten to the flange securing the pair of pants therebetween and forming a waterproof seal. A plurality of fasteners may be used for fastening the backing plate to the flange with the pair of pants therebetween. A plurality of rivets and a rivet gun may be used for fastening the backing plate to the flange with the pair of pants therebetween. At least one seal may be configured for placement between either the flange or the backing plate. A cutting board may be used for placement inside the pair of pants when cutting along the cut path. 
     Other features and advantages of the present invention will become apparent from the following more detailed description, when taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       FIG. 1  illustrates prior art chest waders  100 . These are also equivalent to prior art rain gear. The chest wader  100  may be of rubber, various breathable membranes, such as Cortex® neoprene or any other fabric. In a wading application, a safety belt  102  is typically worn. This is a tightly or snugly fitting belt which prevents the rapid ingress of water into the lower part of the waders if one should, for example, slip into a deep pool in a river. The suspenders  104  are worn over the shoulders and keep the waders held up in place. 
     Referring once again to  FIG. 1 , the waders can actually include an entire family of similar garments. As defined herein, the term “wader” includes chest high waders, waste high waders, foul weather or rain suits, exposure suits, ice rescue suits, survival suits and water rescue dry suits. The term “wader” is also extendable to any type of scuba diving gear, whether they be wet or dry suits. In the broadest sense, the term “wader” as used herein refers to any type of waterproof clothing. In one embodiment, the “wader” could be rain gear where the feet  106 , instead of being sealed to the wader pants, are actually a separate boot and the garment  100  is slipped down over the boots thereby keeping water from entering the boot. In a similar fashion, a rain jacket would be worn (not shown) over the wader along with a built-in hood or a hat. These types of heavy duty marine rain gear systems are worn throughout, for example, the Pacific Northwest where crab fishermen or other fishermen are on the ocean in extreme weather conditions. Ocean passage makers, such as sailors, have similar foul weather gear requirements, particularly for exposure suits. 
     Applications for waders with built-in feet include both traditional and fly fishermen as well as duck hunters and many other types of outdoor sports. For example, the present inventors have used waders extensively in Alaska where one not only wears the waders, but also a rain-type jacket over which (or under) is also placed a fly fishing vest. In addition, there is another belt (not shown) typically disposed somewhat below the safety belt  102 , which can contain a firearm, pepper spray, a knife or similar items. The present inventors also wore hand-held radios, for example, on a belt clip. 
     It is very important when you are hiking and wading to stay properly hydrated. The inventors found this to be a significant problem because urination is not easy when wearing such a system as illustrated in  FIG. 1  and as described. In order to urinate you first have to remove your belt containing the accessories, such as the gun, pepper spray canister and the radio. You also need to remove the fly fishing vest with all of its pockets and the rain jacket. Then you must remove the safety belt  102  and then remove the suspenders  104  at which point you are finally ready to drop down the waders to the point wear you can unzip your pants or pull down your fleece in order to perform the act of urination. When staying properly hydrated, this means, for an average adult male, that this process may be repeated from 5 to 10 times a day. Add the fact that many, if not most, fishermen are male and are in the upper age ranges (i.e. with enlarged prostates) meaning that the urination frequency becomes an enormous problem. 
       FIG. 2  is very similar to  FIG. 1 , but illustrates the present invention of a urinary relief hatch assembly  108  including a lid  110  as shown. This urinary relief hatch  108  can come in many forms as will be shown in subsequent drawings. In general, it has a hermetic watertight seal and a hinge  116  so that it can be easily raised up. In this case, there is either a hook-and-loop fastener patch, a snap or the like  112  which holds the urinary relief lid conveniently up in place. The present invention is best worn with the correct undergarments, such as a fleece with a large flap instead of a zipper so one may easily access the penis. As will be shown in an alternative embodiment, it is also possible for the urinary relief flap  150  to fold downward and simply hang by gravity below the opening in the waders. It is also important that the urinary relief lid  110  be sufficiently large in diameter cross-section to easily access the undergarments. This also makes it easy for a female to use the system along with a complimentary urination device, such as the Go-Girl®. The Go-Girl® is a flexible and soft rubber-like structure that allows women to urinate while standing up. It is a hygienic, portable discrete and reusable device that can be used in concert with the present invention. It would be easy for a female to use a device, such as the Go-Girl® by opening the lid  110  of the present invention and then inserting the Go-Girl® such that it channels bodily fluid out through the open lid  110 . 
       FIG. 3  is taken from section  3 - 3  from  FIG. 2  and shows the urinary relief lid  110  in an enlarged view. Shown is a quick and convenient release snap  114  which is activated by simply pushing down with one&#39;s thumb. The lid  110  automatically flaps open as it is compressed against a rubber O-ring seal or the like attached to the base  105 , which naturally acts as a spring to keep it firmly seated, but also make it open on its own. Also shown is the hinge  116  which in this embodiment, is shown on top of the urinary relief hatch. 
       FIG. 4  is the same as  FIG. 3 , but it shows the relief lid  110  in the open position away from the base  105 . The snap  114  has been pushed down so that it disengages from the snap retainer  128  thereby allowing the entire relief lid  110  to pivot on its hinge assembly  116 . A garment  118  is shown through the relief hatch. In this case, the garment is some sort of a long underwear or fleece. There is an optional flapped opening  120  for convenient access to the penis. Some types of similar garments do not have such a flap, however, during experimentation the inventors found it very easy to pull down such a garment from its elastic band and still easily access the penis. A seal of silicone rubber or similar flexible material is shown  124  which could also be an O-ring. The various types of seals are not limited by the invention, but several examples will be given in subsequent drawings. When the urinary relief lid  110  is closed, it swings down on its pivot  116  until it firmly snaps in place between the snap retainer  128  and the snap assembly itself. A variety of materials can be used for all of these structures as will be discussed in subsequent drawings such as plastics, metals, composites, wood, fiberglass, laminates or combinations thereof. 
       FIG. 5  is very similar to  FIG. 4  except that the undergarment  118 ′ has a zipper  122 . This would be analogous say to a simple pair of jeans. With the relief lid  110  in the open position, one can see that it would be very easy to pull down the zipper  122  to access the penis for urination. It is also noted that the present invention is intended to be used for males, but could also be used for females. Auxiliary devices may be used by females to aid in the use of the present invention. For instance, a hygienic funnel, such as the Go-Girl® may be used by females that help capture and direct urination out through the present invention. 
       FIG. 6  is taken from section  6 - 6  from  FIG. 3 . The urinary relief lid  110  is shown seated closed by virtue of the snap assembly  114 ,  132 . There is a circumferential flexible or deformable seal  124  that is shown that is seated against a seal compressor  126 . One can see how the seal would be formed as it is pressed into the seal compressor  126 . This forms a water-tight seal which is extremely important for waders or heavy duty rain wear. In particular, this is important when wearing waders where this area of the wader is most often times under water. A seal joint  130  is shown which makes a connection between the wader or rain gear garment  100  and the urinary relief hatch assembly  108 . As will be shown, this joint can be of a thermal-setting adhesive, a glue, a rubber bond, a stitch, a thermal bond, a weld, a rivet or any other type of joint that would be waterproof and strong. 
       FIG. 7  was taken from section  7 - 7  from  FIG. 4  and shows the urinary relief hatch assembly  108  in  FIG. 6  in the open position. One can see that the water-tight deformable seal material  124  is no longer indented since it is no longer pressed against the seal compressor  126 . Also, in this embodiment there is a retention assembly attached to the urinary relief handle  132 . As will be shown, this relief hatch retainer  112   a  and  112   b  can be accomplished by a variety of designs. The idea of having the relief hatch in this embodiment open upwards is to provide maximum access to the penis for urinating and taking advantage of gravity so that one does not splash the lid  110  or any of its components with urine. 
       FIG. 7A  is an enlarged view of similar structure of section  7 A- 7 A taken from  FIG. 7  now showing a spring  107 . The spring  107  is biasing the lid  110  to remain open and not fall down and close against the base  105 . This prevents the lid  110  from unwantingly close against the base  105 . 
       FIG. 7B  is an enlarged view of similar structure of section  7 B- 7 B taken from  FIG. 7  now showing a cam mechanism  109 ,  111  in the open position. The cam  109  has a raised portion that interferes with protrusion  111 . In this way when the lid  110  is open it is held in the open position.  FIG. 7C  is an enlarged view of similar structure of section  7 C- 7 C taken from  FIG. 7  now showing the cam mechanism  109 , 111  in the closed position. Here, the raised portion of the cam  109  has passed the protrusion  111  and is no longer being held open. It will be understood that the cam  109  and protrusion  111  could be placed in different locations and different positions. This example merely illustrates that a wide variety of friction joints can be used to keep the lid  110  in the open position so it does not unwantingly close against the base  105 . 
       FIG. 8  is an enlarged view taken from section  8 - 8  from  FIG. 6 . Shown is a portion of the urinary relief lid  110  and the flexible seal  124 . The flexible seal retainer is the sandwich between structures  134   a  and  134   b . The seal  124  is press fit in a way that is held securely or snugly while the relief lid  110  is swung up or down. Also shown is the seal compressor assembly  126 . In the closed position, the deformable or compressible seal  124  is firmly seated against the seal compressor  126  in order to form a water-tight seal. 
       FIG. 9  is very similar to  FIG. 8  and simply shows the urinary relief lid  110  in the process of being swung open. At this point, one can see that the seal material  124  is no longer indented or compressed. 
       FIG. 10  is taken from section  10 - 10  from  FIG. 7 . This is a retainer mechanism so that when the lid is in the upward position, it is held up while one goes about their business of urinating. In the case of  FIG. 10 , this would be opposite polarity magnets so that the lid is held up magnetically in place. 
       FIG. 11  is taken from section  11 - 11  from  FIG. 7  and shows a male and female snap assembly. The female snap  112   a  is affixed to handle  132  and is pressed over the male snap portion  112   b  as shown. There is a retainer clip spring to hold the two firmly together. To unsnap this, one simply pulls against it as it pops off. The male and female portions of the snap may be used on either side. 
       FIG. 12  is taken from section  12 - 12  from  FIG. 7  and is very similar to  FIG. 10 . Shown are a hook-and-loop style attachments, which in the industry are also known as Velcro®. In a preferred embodiment, the part of the hook-and-loop attachment system that is attached to the wader  100  would be larger in diameter or size. This would allow for dimensional misalignments as material stretches or wrinkles. 
       FIG. 13  is very similar to  FIG. 3  except that the urinary relief hatch assembly  108  has more of a triangular shape and also has a different type of container and catch mechanism. For strength, in a preferred embodiment, the hinge  116  is shown full width. A compression latch  136  is used to compress the lid  110  against an O-ring seal  140 . The O-ring seal  140  is fitted into a groove  141 , which is better shown in  FIG. 14 .  FIG. 14  shows the urinary relief hatch  108  of  FIG. 13  in the open position. One can see the compression latch  136  and the compression latch retainer  138 . The compression latch, when pushed down, compresses the edge of the lid  110  firmly against the O-ring  140  which ratchet seals it and makes it water tight. It will be obvious to those skilled in the art that any number of alternative dimensions could be used to provide convenient access for urination. It will also be obvious to those skilled in the art that any of the retention devices as previously illustrated in  FIGS. 10 ,  11  and  12  may be adapted to the mechanism as illustrated in  FIGS. 13 and 14 . 
       FIG. 15  is a sectional view taken from section  15 - 15  from  FIG. 13 . It shows the lid  110  in the closed position with the compression latch  136  firmly seated in place, which is compressing O-ring  140  in both the axial and side load directions. This forms a very tight water-tight seal. Item  142  is a very rigid seating assembly for the O-ring, which also holds it firmly in place. It is really hard to visualize how the O-ring  140  is seated while it is compressed like this. One is referred to  FIG. 16 , which is taken from section  16 - 16  from  FIG. 14 . This shows the urinary relief lid  110  in the open position. With this in the open position, one can now clearly see the O-ring  140  in its uncompressed state. One can also see that there is a little groove or slot  144  into which the O-ring is firmly seated. To replace the O-ring, one expands the O-ring by stretching it in diameter and then slips it into this slot where it snaps firmly into place where it cannot come out. An alternative (not shown) would be to add some silicone grease all along the O-ring, which helps it to form a water-tight seal. 
       FIG. 17  is taken from section  17 - 17  from  FIG. 15  and shows an enlarged view of the compression latch  136  firmly seated against its retainer  138 . This firmly compresses the O-ring  140  as shown, forming a water-tight seal. 
       FIG. 18  is very similar to  FIG. 17  except in this case, the O-ring is in straight compression when the lid  110  is seated. That is, the edge of lid  110  presses straight down against the O-ring, which causes it to change shape from a circle to more of an oval. Again, this forms a solid water-tight seal. Referring back to  FIGS. 15 ,  16 ,  17  and  18 , one can also see that there is a joint  146  between the wader or rain gear material and a groove that is formed in the urinary retention device  108 . The material  100  is held firmly in this groove  146  by compression, by glues or cements, by thermal-setting adhesives or the like. 
       FIG. 19  is very similar to  FIGS. 2 ,  13  and  14  except that in this case, the hinge  116  has been inverted so that it appears towards the bottom. In this case, there is no need for any type of retention device as previously illustrated in  FIGS. 10 ,  11  and  12 . In this case, the lid  110  flaps down and is held simply in place by gravity while one goes about the process of urination. One advantage of this assembly as illustrated in  FIG. 19  is its simplicity and reduced costs. Cost is reduced by not needing to provide for a retention device to hold the lid in the upward position. There are also some geometry advantages to the structure as illustrated in  FIG. 19  as this provides a more open access through the undergarment. 
       FIG. 20  illustrates a different type of O-ring compression assembly and is similar to those previously described in  FIGS. 15 through 18 . In the case of  FIG. 20 , one simply pushes downward on latch mechanism  114  while at the same time, pulls up on the handle mechanism  132 . This allows one to swing the lid  110  into its opening position  110 ′. As can be seen, in this configuration, the O-ring  140  is in direct compression. An alternative to  FIG. 20  is shown in  FIG. 21  and is very similar except that the O-ring is in both side and axial compression. 
       FIG. 22  is yet another type of latch retainer mechanism  148  which pivots on a hinge. One can see that by applying their thumb to location  114 , it is easy to rotate this latch so that the lid  110  can be swung into its open position  110 ′. 
       FIG. 23  is an alternative view of the wader relief mechanism  108  as previously illustrated in  FIGS. 2 ,  19  and any alternative thereof. In this case there is a flap  150  which covers over the urinary relief mechanism  108 , but preserves a better cosmetic look for the garment. The flap  150  may be of the same material as the wader itself. It may be held down by hook-and-loop type closures. 
       FIG. 24  is the same as  FIG. 23  which illustrates the flap  150  without the dash lines showing the present invention  108  underneath. One can see by looking at  FIG. 24  that this does provide a better cosmetic appearance. 
     There are several possibilities for the marketing of the urinary relief hatch assembly  108  of the present invention. One would be during original manufacturing of the wader and the rain garment, to simply install the urinary relief hatch at that time. Compatible materials would be used so that automated thermal-bonding or glue/adhesive processes can be used to join the wader material  100  to a flange  130 , which is part of the urinary relief mechanism  108 . However, there is a very important aftermarket. Many people already own very expensive waders and would like to retrofit their waders to add the urinary relief mechanism  108 . 
       FIG. 25  illustrates a kit which may be sold as an aftermarket assembly. The kit would contain the urinary relief hatch  108  of the present invention along with a template  152  which would come with instructions and in a preferred embodiment, a sticky adhesive  158  so that this could be placed on the garment. One could then either use the template  152  to trace a line with permanent ink, or use it as a cutting template to take a sharp knife  154  or scissors and cut an appropriate opening in the wader garment  100 . A convenient cutting board  156  may be optionally supplied which can be placed inside and behind where the cutting is to take place. This backing board  156  is very important because it would destroy the waders to cut through both the front and back sides at the same time. 
       FIG. 26  illustrates placing the backing or cutting board  156  inside the wader in the appropriate location and roughly centered over template  152 . Also shown, are a number of glues, adhesives or even epoxies  158  which may be used. There would be a variety of bonding agents  158  supplied in the kit along with instructions so that the user can properly identify which type of wader they have and what type of material it has and therefore what kind of sealant it will be compatible with. 
       FIG. 27  illustrates the use of the template  152  and the cutting tool  154  to make the primary opening in the front of the waders  100 . 
       FIG. 28  shows the opening  160  into which the urinary relief assembly  108  is fitted into place. As one can see, the appropriate adhesive material  158  is first applied and then the urinary relief hatch is placed into the hole  160 . This can be done through the inside as shown or from the outside (not shown). 
       FIG. 29  is a kit very similar to  FIG. 25  and is used in very much the same way. Provided are two compressible rubber or neoprene or the like gaskets  162  and  164 . There is also a cutting template  152  and a backing board  156  along with the appropriate adhesives  158  as previously described in  FIG. 25 . In lieu of the adhesives, a pop rivet tool  166  may be provided along with the appropriate number of pop rivets  168  so that one can literally sandwich the wader material  100  (not shown) between the two gaskets  162  and  164  and then pop rivet everything in place. Pop rivets can press together solidly as they are tightened by compressing the two gaskets  162  and  164 , which are flexible. This provides a water-tight seal all around the periphery of the urinary retention device  108 . It will be obvious to one skilled in the art that any other type of fastener, such as screws and small bolt heads and the like may be used. 
       FIG. 30  is an enlarged view showing the use of the template  152  and backing plate  156  previously described in  FIG. 29 . 
     As shown in  FIG. 31 , the various components of the assembly are lined up. An adhesive, sealant or glue  158  is optionally applied prior to the seating of the components. The pop rivet gun  166  is used to place pop rivets  168  through each of the holes. The completed assembly, as shown in  FIG. 32 , forms a water-tight urinary relief hatch of the present invention. A backing plate  170  is provided for which to place the pop rivets. It is important that the backing plate  170  be of a rigid material and that the pop rivet holes or screw holes be placed close enough apart so that the gaskets  162  and  164  are uniformly compressed in a way that water cannot ingress. 
       FIG. 33  is a sectional view taken from section  33 - 33  from  FIG. 32 . Shown is the pop rivet  168  along with the cross-sectional view of the flange of the urinary retention device of wader material  100  along with the two gaskets  162  and  164 . In a preferred embodiment, only one gasket  162  or  164  is needed to form a reliable seal.  FIG. 33  shows the male end of the rivet  168   a  being inserted through the flange of the urinary retention block  172 , through sealing gasket  162 , through a pre-punched hole in the wader material  100  and through the secondary gasket  164  lined up with the holes in the retention flange  170 . 
       FIG. 34  is very similar to  FIG. 33  showing the rivet in its compressed state. As can be seen, gaskets  162  and  164  have been firmly compressed against the wader material or rain gear material  100 . In an optional embodiment, an adhesive  158  may be placed over both ends of each of the pop rivets to make sure that they do not leak water. 
       FIG. 35  is an alternative form of the invention with a twist cap lid  110  with taper engagement slots  176  which are designed to engage pins  174 . As the cap is twisted, it is compressed against gasket seat  126 . There is a gasket on the inside of the twist housing  110  (not shown). As the twist cap  110  is tightened, the gasket (not shown) is compressed against the gasket seat  126  in order to affect a water-tight seal. There is an optional tether  178  which can be of any suitable material which prevents the cap  110  from getting lost. Additionally, the tether  178  may be attached to the side of the wader such that when the lid  110  is opened, the lid  110  will be out of the way during urination. Alternatively, the tether  178  may be made of an elastic material such that the lid  110  is retracted further away from the aperture when opened. Referring once again to  FIG. 35 , one can see that this design offers a number of advantages, in that it is very quick and easy to use. Only a slight rotation of the cap lid  110  is required to engage the pins  174  and properly seat the gasket structure. 
       FIG. 36  is another type of round cap  110 , but in this case, it has female threads  180  which are designed to engage male threads  182  of the O-ring seat  126 . When the cap  110  is threaded down tightly, O-ring  124  is compressed against the O-ring seat  126  which affects a water-tight seal. Again, there is an optional tether  178  shown for the same purposes as previously described in  FIG. 35 . The tether  178  is rotatively attached to the center of the cap  110  so that it does not get tangled up as the cap  110  is screwed in place. 
     Although several embodiments have been described in detail for purposes of illustration, various modifications may be made to each without departing from the scope and spirit of the invention. Accordingly, the invention is not to be limited, except as by the appended claims.
