Title: Adjustable opening for a hunting blind

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims priority under 35 U.S.C. § 119(e) to U.S. Provisional Patent Application Ser. No. 62/141,926 filed Apr. 2, 2015, which is incorporated herein in its entirety by reference. 
    
    
     FIELD OF THE INVENTION 
     The invention generally relates to hunting blinds for use by hunters, photographers, or outdoorsmen. More specifically, the invention relates to hunting blinds with adjustable openings and pass-through features. 
     BACKGROUND OF THE INVENTION 
     Outdoorsmen such as hunters, nature observers, bird watchers, photographers, etc. usually prefer to remain hidden from the wildlife that they are hunting or studying. Hunting blinds are devices that cover and conceal a hunter to reduce the likelihood of detection. Early examples of hunting blinds include the cocking-cloth, a canvas and stick device that allowed hunters to approach pheasants. While early hunting blinds were relatively simple in design, modern hunting blinds may be complex and approach the size of a small house. Modern hunting blinds typically comprise one or more openings through which a user may have access to the outside environment. 
     Modern hunting blinds, including permanent structures and portable blinds, have limited functionality with respect to openings. Prior art hunting blinds typically have openings on one or more sides of the hunting blind; however, the size and location of these openings are fixed or relatively fixed. Examples of these hunting blind may be found in U.S. Pat. Nos. 8,776,814, 8,826,927, and 8,915,258, which are hereby incorporated by reference in their entirety. However, these fixed openings may not be effective for different sized users or different terrain. For example, a young hunter may require an opening in a different position that an older, taller hunter. Similarly, a hunting blind set up on a hillside may have openings oriented into the ground or into the sky. Moreover, there is a large variation in user size and terrain, and thus fixed openings hinder the ability of a user to function within a hunting blind. 
     In addition, different hunting endeavors may require different fields of view. Some hunting endeavors may require a larger field of view, for example, when bird hunting. Other hunting endeavors may necessitate a narrow field of view to avoid detection. Yet other endeavors such as animal watching and photography may require other fields of view. To accommodate these different endeavors, a user would have to buy several different types of hunting blinds specifically tailored for the particular use. This dramatically increases costs. Therefore, there is a need for an improved hunting blind that can accommodate various activities terrain, and individual stature that require different opening characteristics from a hunting blind. 
     SUMMARY OF THE INVENTION 
     It is thus an aspect of embodiments of the invention to provide a hunting blind with a highly adjustable opening. One or more covers may be used to manipulate an opening in the exterior wall of the hunting blind to produce a modified opening. Further, the covers may also comprise a relatively elastic material, thus allowing the covers to suit different requirements for different activities, terrain, and user stature. 
     The covers may employ fasteners and straps to manipulate the size and the shape of the modified opening. A cord may be positioned on the edges of top and bottom covers, and a plurality of first fasteners may be positioned long the cord. Second fasteners may be positioned in a variety of locations on the hunting blind. For example, second fasteners may be positioned on an inner surface of the hunting blind and/or vertical straps positioned proximate to a hub or a corner of the hunting blind. The fasteners selectively interconnect to each other such that the cord, and thus the edge of the covers, is manipulated and the cover takes on various sizes and shapes. 
     It is another aspect of embodiments of the invention to provide a hunting blind with a pass-through feature in the exterior wall that allows selective access to the external environment. In some embodiments, the pass-through feature allows a tripod to be positioned closer to the exterior wall and save space within the hunting blind. One of tripod&#39;s legs may extend through the pass-through feature. A sleeve may be positioned over an opening of the pass through feature wherein the sleeve receives the tripod leg and unfurls as the tripod leg extends through the pass-through feature. This sleeve prevents the typically metallic legs of a tripod from disrupting the camouflaging function of the hunting blind. 
     One particular embodiment of the present invention is a portable blind with an adjustable opening, comprising an exterior wall defining an interior volume; an opening in the exterior wall, the opening having a first area; a top cover partially closing the opening, the top cover having a bottom edge, wherein the bottom edge at least partially defines a passage extending along the top cover; a bottom cover partially closing the opening, the bottom cover having a top edge, wherein the top edge at least partially defines a passage extending along the top cover; a vertically oriented strap positioned at an edge of the exterior wall, the strap having a first end and a second end, the first end selectively interconnected to an upper portion of the exterior wall and the second end selectively interconnected to a lower portion of the exterior wall such that the strap extends across the opening, the strap having a plurality of first fasteners; a first cord disposed in the passage of the top cover, wherein at least one second fastener on the first cord is selectively interconnected to the plurality of first fasteners on the strap to control a position of the bottom edge of the top cover over the opening; and a second cord disposed in the passage of the bottom cover, wherein at least one second fastener on the second cord is selectively interconnected to the plurality of first fasteners on the strap to control a position of the top edge of the bottom cover over the opening, wherein the top cover and the bottom cover at least partially define a modified opening having a second area, wherein the first area is larger than the second area. 
     Embodiments of the system may comprise additional features. For example, in some embodiments, the top cover has a first shape in a relaxed state, and the top cover has a second shape in a tensioned state when the first cord is selectively interconnected to the strap, wherein the first shape is distinct from the second shape. 
     Another particular embodiment of the present invention is a portable blind with an adjustable, variable access opening, comprising an exterior wall defining an interior volume; an opening in the exterior wall, the opening having a first area; a top cover partially closing the opening, the top cover having a bottom edge, wherein the bottom edge at least partially defines a passage extending along the top cover; a bottom cover partially closing the opening, the bottom cover having a top edge, wherein the top edge at least partially defines a passage extending along the bottom cover; a first cord disposed in the passage of the top cover, the first cord selectively interconnected to an inner surface of the exterior wall to control a position of the bottom edge of the top cover over the opening; and a second cord disposed in the passage of the bottom cover, the second cord selectively interconnected to the inner surface of the exterior wall to control a position of the top edge of the bottom cover over the opening, wherein the top cover and the bottom cover at least partially define a modified opening having a second area, wherein the first area is larger than the second area.

It should be understood, of course, that the invention is not necessarily limited to the particular embodiments illustrated herein. 
     DETAILED DESCRIPTION 
     The invention has significant benefits across a broad spectrum of endeavors. It is the Applicant&#39;s intent that this specification and the claims appended hereto be accorded a breadth in keeping with the scope and spirit of the invention being disclosed despite what might appear to be limiting language imposed by the requirements of referring to the specific examples disclosed. To acquaint persons skilled in the pertinent arts most closely related to the invention, a preferred embodiment that illustrates the best mode now contemplated for putting the invention into practice is described herein by, and with reference to, the annexed drawings that form a part of the specification. The exemplary embodiment is described in detail without attempting to describe all of the various forms and modifications in which the invention might be embodied. As such, the embodiments described herein are illustrative, and as will become apparent to those skilled in the arts, may be modified in numerous ways within the scope and spirit of the invention. 
     Although the following text sets forth a detailed description of numerous different embodiments, it should be understood that the detailed description is to be construed as exemplary only and does not describe every possible embodiment since describing every possible embodiment would be impractical, if not impossible. Numerous alternative embodiments could be implemented, using either current technology or technology developed after the filing date of this patent, which would still fall within the scope of the claims. To the extent that any term recited in the claims at the end of this patent is referred to in this patent in a manner consistent with a single meaning, that is done for sake of clarity only so as to not confuse the reader, and it is not intended that such claim term by limited, by implication or otherwise, to that single meaning. 
     Various embodiments of the invention are described herein and as depicted in the drawings. It is expressly understood that although the figures depict hunting blinds, covers, and fasteners, the invention is not limited to these embodiments. Further, terms such as “fasteners,” “first fasteners,” and “second fasteners” as well as “hunting blind” and “portable blind” may be interchangeable in some instances. 
     Now referring to  FIG. 1A , a front view of a hunting blind  2  with an adjustable opening  10  is provided. The hunting blind  2  has an exterior wall  4  that defines an interior volume of the hunting blind  2  where a user may set up gear for hunting, photography, etc. The exterior wall  4  of a portable hunting blind  2 , like the blind in  FIG. 1A , is typically made from a material that is collapsible. Thus, the hunting blind  2  comprises a plurality of hubs  6  and poles  8  that serve as a frame. The ends of the poles  8  are typically interconnected to the corners of the exterior wall  4 . In a collapsed state, the poles  8  are generally parallel to one another, and the exterior wall&#39;s  4  material is loose. In an opened state, the poles  8  spread out from one another until the poles  8  and hub  6  lie in a common plane. The hub  6  continues to extend outward and “pops” into place such that the exterior wall&#39;s  4  material is taught and extends outward and away from the center of the hunting blind  2  to provide the user with additional room and to provide the hunting blind  2  with additional structural integrity. 
     An opening  10  is disposed in two walls of the hunting blind  2  in  FIG. 1A . The opening  10  is a portion of the hunting blind  2  that does not comprise an exterior wall  4 . A top cover  12  is disposed on the top side of the opening  10 , and a bottom cover  14  is disposed on the bottom side of the opening  10 . Together, the top and bottom covers  12 ,  14  can manipulate the shape of the opening  10  into a modified opening wherein the modified opening has a smaller area than the entirety of the opening  10 . The modified opening is customizable to suit any activity including different types of hunting, animal watching, and photography. 
     One or more of the covers  12 ,  14  may be comprised of a material that permits the covers  12 ,  14  to change between a first shape and a second shape. Thus, in some embodiments, a cover may comprise between about 1% and 50% elastane, neoprene, or other stretchable material. In various embodiments, a cover may comprise between about 5% and 20% elastane, neoprene, or other stretchable material. Further, these materials may be incorporated into a cover such that the cover stretches only in discrete directions, for example, one or two directions. 
     Now referring to  FIG. 1B , a front view of a hunting blind  2  that does not have top and bottom covers  12 ,  14  is provided. The opening  10  in the exterior wall  4  is shown in its entirety. In view of  FIG. 1A , it is shown that the covers  12 ,  14  are configured to change the size and shape of the opening  10  in  FIG. 1B . 
     Now referring to  FIG. 2 , a view of the top and bottom covers  12 ,  14  from inside the hunting blind  2  is provided. A hub  6  and pole  8  combination is in an opened state and is providing rigidity to a portion of the exterior wall  4  of the hunting blind  2 . The exterior wall  4  extends upward to provide a location where the hub  6  may be disposed. The remaining non-exterior wall  4  area is part of the opening  10  of the hunting blind, and the top and bottom covers  12 ,  14  manipulate the opening  10  into a modified opening. 
     A cord  20  is disposed along the top edge  18  of the bottom cover  14 , and in this embodiment, the cord  20  has elastic properties, which means that the cord  20  returns to an initial length after being stretched or otherwise distorted to a second length. It will be appreciated that in some embodiments, the cord is inelastic but otherwise adjustable to accommodate changes between a plurality of lengths. The edge is stitched or otherwise secured to the bottom cover  14  to provide an interior volume or top edge&#39;s passage  18  through which the cord  20  may be disposed. The cord  20  emerges from either end of the top edge&#39;s passage  18 . 
     A plurality of first fasteners  22  may be interconnected to the cord  20  at various positions along the cord  20 . In the embodiment shown in  FIG. 2 , a first fastener  22  is interconnected to a first end of the cord  20  and a second end of the cord  20  such that all of the first fasteners  22  are disposed outside of the top edge&#39;s passage  18 . In addition, one or more first fasteners  22  may be interconnected to an outer surface of the covers  12 ,  14 . 
     A plurality of second fasteners  26  is disposed on a strap  24  and provides a location for first fasteners  2  to selectively interconnect. The strap  24  is interconnected to the exterior wall  4 . In the embodiment in  FIG. 2 , the strap  24  is oriented vertically and interconnected to the exterior wall  4  above the hub  6  and the exterior wall  4  above the top cover  12 . The strap  24  in this embodiment includes plastic buckles at each end such that the strap  24  may be optionally removed from the hunting blind  2 . In other words, the strap  24  is removably interconnected to the exterior wall  4 , and the strap  24  can have fasteners at either end, including buckles, that interface with complementary features on the exterior wall  4  to provide the removable interconnection. Further, the strap  24  is adjustable in length to accommodate different sized hunting blinds  2 . 
     A first fastener  22  in  FIG. 2  is disposed on an outer surface of the bottom cover  14  proximate to the bottom cover&#39;s  14  top edge  18  and proximate to a midpoint of the top edge  18 . Another view of the first fastener  22  disposed on the cover is provided in  FIG. 4A . The first fastener  22  extends upwards and selectively interconnects to one of the second fasteners  26  disposed on the strap  24 . This selective interconnection allows the cord  20  and the bottom cover&#39;s  14  top edge  18  to be configured in a number of ways to provide a modified opening. In alternative embodiments of the invention, this first fastener  22  may be interconnected to a midpoint of the cord  20 , which emerges from the passage to selectively interconnect to one of the second fasteners  26 . 
     A first fastener  22  disposed on one end of the cord  20  is selectively interconnected to a second fastener  26  that is interconnected to the exterior wall  4 . This pulls a corner of the lower cover  14  out of the opening  10  of the exterior wall  4  to provide a modified opening. It will be appreciated that second fasteners  26  may be positioned at any location on the exterior wall  4  or any other component of the hunting blind  2 . It will be further appreciated that the first fasteners  22  may not be identical to each other. For example, the first fastener  22  at the ends of the cord  20  may be a carabiner-like hook while the first fastener  22  on the outer surface of the bottom cover  14  may be a plastic buckle. 
     In addition to the description of the strap  24  with respect to  FIG. 2 , it will be appreciated that embodiments of the present invention may include a strap  24  at other locations on the hunting blind. For example, in  FIGS. 1A and 1B , a strap is shown at an edge of the exterior wall of the hunting blind. In yet further embodiments, a hunting blind may have multiple straps, for example, one strap at an edge of the hunting blind and two additional straps, each adjacent to a hub of the hunting blind. 
     Now referring to  FIG. 3 , another view of the top and bottom covers  12 ,  14  from inside the hunting blind  2  is provided. The bottom cover  14  comprises a cord  20 , and a first fastener  22  is disposed on an end of the cord  20 . The first fastener  22  is selectively interconnected to a second fastener  26  disposed on an inner surface of the exterior wall  4 . A plurality of second fasteners  26  is disposed on the inner surface of the exterior wall  4  to provide a number of locations to selectively interconnect with the first fastener  22 . Thus, the bottom cover  14  may be configured in a number of ways to provide a modified opening. 
     Similarly, the top cover  12  also comprises a cord  20  and a first fastener  22  disposed on an end of the cord  20 , wherein a plurality of second fasteners  26  provides a range of locations to selectively interconnect with the first fastener  22 . It will be appreciated that the top and bottoms covers  12 ,  14  may not necessarily both have a cord  20  and first fastener  22  combination. For example, in one embodiment the cords  20  for the covers  12 ,  14  may have a different number of first fasteners  22 . In yet further embodiments, the hunting blind  2  may only comprise one of the top cover  12  and the bottom cover  14 . Similarly, in some embodiments, the hunting blind  2  may comprise more than two covers  12 ,  14 . The hunting blind  2  may comprise a top cover  12 , a bottom cover  14 , a left cover, and a right cover where the covers are configurable to provide a modified opening. 
     Also shown in  FIG. 3  is a third fastener  28  disposed along a side edge of the top cover  12 , and another third fastener  28  is disposed along a side edge of the bottom cover  14 . The third fasteners  28  seal the side edges of the covers,  12 ,  14  to help protect the internal environment of the hunting blind  2 . The third fasteners  28  also help the covers  12 ,  14  define a modified opening. In the embodiment in  FIG. 3 , the third fasteners  28 . However, it will be appreciated that the third fasteners  28  may be any type of fastener discussed elsewhere herein. 
     Now referring to  FIGS. 4A and 4B , detailed views of a first fastener  22  and a first fastener  22  selectively interconnected to a second fastener  26  are provided, respectively. The first fastener  22  in  FIG. 4A  has a carabiner-type shape that comprises a nose, basket, and spine. The first fastener  22  may also have an optional gate portion that selectively encloses the central area of the first fastener  22 . The first fastener  22  may also have carabiner-like, including an oval shape, a regular D shape, an asymmetrical D shape, and a pear shape. 
     The second fastener  26  is a ring that is interconnected to the strap  24  via a small portion. To selectively interconnect the first and second fasteners  22 ,  26 , the nose of the first fastener  22  hooks onto the second fastener  26 . When the first fastener  22  is pulled taught, the second fastener  26  is positioned on the basket portion of the first fastener  22 . The spine of the fastener  22  is the long portion positioned opposite the gap where an optional gate portion may be positioned. 
     It will be appreciated that the first and second fasteners  22 ,  26  are not the only fasteners contemplated by embodiments of the invention. For example, a fastener may be a plastic buckle, a snap fastener, Velcro®, a hook-and-loop fastener, a three-ring release system, an bolt, a bayonet mount, a binder clip, a brass fastener, an R-clip, a bungee cord, a cable tie, a circle cotter, a clevis fastener, a lobster clasp, a Terry clip, a zipper, a permanent magnet, an electromagnet, or any other fastener that selectively interconnects two components together. 
     Now referring to  FIGS. 5 to 8 , various configurations of the hunting blind&#39;s  2  top and bottom covers  12 ,  14  are provided. The hunting blind&#39;s  2  covers  12 ,  14  in  FIG. 5  are in a closed state. This means that the modified opening&#39;s area is equal to zero. 
     Now referring to  FIG. 6 , the hunting blind&#39;s  2  covers  12 ,  14  are in a first configuration. The top cover  12  is fully extended downward, and the hunting blind&#39;s  2  bottom cover  14  is also in a downward position. This configuration pushes the modified opening lower on the hunting blind  2 . 
     Now referring to  FIG. 7 , the hunting blind&#39;s  2  covers  12 ,  14  are in a second configuration. The covers  12 ,  14  meet in the middle of the opening  10 , but the covers  12 ,  14  remain open on each side of the opening  10 . The resulting modified opening is actually two separate openings, one disposed on either side of the hunting blind  2 . 
     Now referring to  FIG. 8 , the hunting blind&#39;s covers  12 ,  14  are in a third configuration. The top cover  12  is fully extended downward, and the bottom cover  14  is partially extended upward such that the bottom cover&#39;s  14  top edge is not parallel with the ground. Instead, a midpoint of the bottom cover&#39;s  14  top edge is positioned lower than the top edge&#39;s two ends. 
     It will be appreciated that the hunting blind&#39;s covers  12 ,  14  may have a variety of additional configurations. For example, in fourth configuration, the top cover  12  is fully extended downward, but the hunting blind&#39;s  2  bottom cover  14  is partially extended upward such that the bottom cover&#39;s  14  top edge is substantially parallel with the ground. In a fifth configuration, the top cover  12  and the bottom cover  14  meet at the sides of the opening  10 , but the midpoint of the top cover&#39;s  12  bottom edge extends upward, and the midpoint of the bottom cover&#39;s  14  top edge extends downward. This configuration leaves the modified opening positioned in the center of the opening  10 . 
     In a sixth configuration, the midpoint of the top cover&#39;s  12  bottom edge extends downward while the ends of the bottom edge remain upward. The midpoint of the bottom cover&#39;s  14  top edge extends downward while the ends of the top edge extend upward. In a seventh configuration, the midpoint of the top cover&#39;s  12  bottom edge extends upward while the ends of the bottom edge extend downward. The midpoint of the bottom cover&#39;s  14  top edge extends upward while the ends of the top edge extend downward. 
     Now referring to  FIG. 9 , a pass-through feature  30  is provided. The pass-through feature  30  comprises an opening  32  in the exterior wall  4  of the hunting blind that allows objects, such as a tripod, to pass through the exterior wall  4 . In the specific case of the tripod, the pass-through feature  30  allows the tripod and any instruments disposed on the tripod to be closer to the exterior wall  4 . This helps increase the available space within the hunting blind because the entirety of the tripod does not need to be disposed in the hunting blind. 
     The opening  32  in  FIG. 9  is a lateral slot that is oriented substantially parallel with the ground. It will be appreciated that the pass-through opening  32  may come in a variety of configurations and orientations. For example, the opening  32  may be oriented vertically with one end positioned proximate to the ground. In addition, the opening  32  may be disposed on any component of the hunting blind, including the covers discussed elsewhere herein. 
     Two straps  34  are positioned across the opening  32  to maintain the integrity of the exterior wall  4 . These straps  34  are interconnected to the exterior wall  2  on either side of the opening  32 . In some embodiments, the pass-through feature  30  may comprise zero, one, or three or more straps  34 . Further, the straps  34  may be selectively interconnected to the exterior wall  4  using any type of fastener discussed elsewhere herein. 
     A sealing flap  36  is positioned proximate to the opening  32  of the pass-through feature  32 . The flap  36  is oriented substantially parallel to the ground with one side of the flap  36  interconnected to the exterior wall  4 . The flap  36  may rotate about this interconnection to cover the opening  32 . Fasteners disposed on the flap  36  and the exterior wall  4  allow the flap  36  to selectively interconnect to the exterior wall  4 . This allows the flap  36  to cover the opening  32  when the pass-through feature  30  is not in use to protect the interior of the hunting blind against the environmental elements. It will be appreciated that the fasteners disposed on the flap  36  and the exterior wall  4  may be any fasteners described elsewhere herein. 
     Also shown in  FIG. 9  is a tripod  40  in the hunting blind is positioned close to the pass-through feature  30 , and one of the tripod&#39;s  40  legs physically passes through the pass-through feature  32 , which allows the tripod  40  set closer to the exterior wall  4  and preserve space within the hunting blind. While this exemplary figure shows a tripod  40 , the pass-through feature  30  has many other applications. For example, the pass-through feature  30  may be used to vent air from the hunting blind, to provide a line of sight out of the hunting blind, to dispose instruments for monitoring environmental conditions, to place scents, etc. 
     The pass-through feature  30  may also comprise a sleeve that conceals the tripod&#39;s  40  leg. Tripods  40  and other devices are often made from metallic or other reflective materials. Thus, it is desirable to maintain the camouflage function of the hunting blind  2 , even when a pass-through feature  30  is used. The sleeve may interconnect or selectively interconnect to at least a portion of the opening  32 , and the sleeve may encapsulate the tripod  40  leg as the leg extends through the pass-through feature  30 . Therefore, when the tripod  40  leg is fully extended through the pass-through feature  30 , the sleeve camouflages the leg and maintains the overall camouflage function of the hunting blind  2 .
