CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This Application is a Non-Prov of Prov (35 USC 119(e)) application 61/020,047 filed on Jan. 9, 2008 and entitled Adaptable Tree Blind for Ladder Stand and Tree Stands. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The present invention relates generally to hunting blind assemblies and the like. More specifically, the present invention discloses an adaptable and covered tree blind that can be used in an elevated condition with conventional tree stands and ladder stands. The hunting blind is configured to completely surround an entire area of the tree or ladder stand, providing the hunter with total concealment while providing protection against weather conditions. 
       BACKGROUND OF THE INVENTION 
       [0003]    The present invention is documented with numerous examples of tree blind and collapsible shelter designs. The objective of such articles and assemblies is typically in providing some degree of either environmental shielding/insulation to the occupant, as well as further providing either or both of camouflage for shielding the occupant&#39;s presence, as well as providing for easy manipulation of weaponry (e.g. long barreled firearms and bows) carried by the occupant. 
         [0004]    U.S. Pat. No. 4,933,019, issued to Peruski, teaches a version of a collapsible portable shelter including a plurality of cover supporting frame bars pivotally mounted at one end of a central hub, this further including vertically spaced apart plates. The frame bars include inverted L shaped support bars, each with a generally vertical and ground supporting leg and in integral and generally horizontal base received between the upper plates. This enables a terminal end of the horizontal base to be pivotally mounted in an aperture provided in one of the plates and, in combination with a recess arrangement defined in the other plates and the incorporation of a spring mechanism urging the plates together, facilitates holding the horizontal members within their defined recesses, but allowing the members to be rotated between stowed (side-by-side) and angularly disposed (spread apart) positions consistent with the pattern of the recesses. 
         [0005]    U.S. Pat. No. 6,089,245, issued to Tseytlin, discloses a collapsible sun shade with hinged arms. The arms support a flexible sheet with a hub generally positioned at its center, and further such that the distal ends of the arms are connected to the sheet to support the same when the arms are spread apart. 
         [0006]    U.S. Pat. No. 7,246,630, issued to Ransom, teaches a pre-assembled and collapsible tree stand hunting blind which folds into a compact package, and utilizing coil-able steel frame members which may be collapsed. The enclosure is adapted to be attached to the trunk of a tree and to an associated platform, such as a hunters tree stand. The enclosure is further provided with camouflage elements to render the user relatively invisible to game in the surrounding environment. Reference is also made to the collapsible structure with top supporting elements in Ransom U.S. Pat. No. 7,137,399. 
         [0007]    Additional references of note include each of the versatile hunting or animal watching blind in Hanson 2006/0249640, the hunting blind and method of use in Maddox U.S. Pat. No. 7,182,091 and the hunting stand and blind in Hodnett U.S. Pat. No. 6,510,922. 
       SUMMARY OF THE INVENTION 
       [0008]    An adaptable blind for ladder stands and tree stands includes a platform that secures to a tree stand or ladder stand associated platform. A frame is assembled upon the platform and includes a plurality of upwardly extending and arcuately configured poles, these collectively establishing a superstructure which defines a three dimensional interior. A cover is assembled over the frame and encloses the interior, at least one access location in the cover material permitting a user to ingress and egress to and from the interior A combination seat and ladder can be separately provided and which is both secured to the tree or pole as well as supported upon or against the platform. 
         [0009]    Additional features associated with the platform include the provision of a plurality of interconnected length and width extending members, a further plurality of adjustable clamps associated with locations of the platform and which are adapted for receiving at least one of a tree or ladder stand platform of given dimensions. The clamps further include such as hooks capable of being fastened in order to draw the platform tight against a stand portion associated with the ladder. A plurality of channels are arranged in spaced apart and parallel extending fashion within the platform, the hooks being displaceably mounted within the channels and laterally adjusted to provide adaptability between multiple sized tree stands. 
         [0010]    The poles each further exhibit an elongated and angled member which is secured at a lower end to a selected corner inserting location integrated into the platform and, at an upper end, in pivotally displaceable and interconnecting fashion with an upper support assembly, and to which the other poles are likewise secured. These may further include such as frame supported bracket fixtures located at corner locations of said platform and to which are secured said poles. 
         [0011]    The upper support assembly includes a top plate and a spaced apart lower support plate, each of which includes mating apertured locations for receiving upper configured ends associated with each of the poles. In this fashion, the poles may be rotatably converted between expanded use and collapsed storage positions. 
         [0012]    The cover further includes at least one of a canvas, mesh or fabric material, this further defining at least one access door located on a first selected side and at least one window being formed along one or more additional sides. According to additional variants, the cover can exhibit a specified shape and size and include a camouflage or other suitable decorative pattern.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0029]    As will be described in additional detail in reference to the various illustrations disclosed herein, the adaptable hunting blind consists of three basic parts which are generally referenced to include a fabric, canvas, or mesh cover  10  (such as shown in detail in each of  FIGS. 4-6  and which can exhibit any of a desired decorative or camouflage pattern), a frame (as generally shown at  12 ) and a platform  14 . A more detailed description of the frame  12  and platform  14  will be had upon reference to the various succeeding illustrations of  FIGS. 1-3 , whereas additional illustrations and associated description directed to the covering material  10  is further provided in reference to  FIGS. 4-6 . 
         [0030]      FIG. 1  is an environmental view of an adaptable tree blind in a first application in use with an optional ladder stand, whereas  FIG. 2  is an enlarged perspective of the collapsible superstructure and platform associated with the tree blind and  FIG. 3  is an enlarged and partially rotated view of the platform in  FIG. 2 . The blind&#39;s platform  14  connects the blind assembly to an optional associated ladder stand platform and which, as illustrated, includes a ladder portion  16 , an angled, generally U shaped platform  18  (this extending in angular fashion from each of the spaced apart linear extending portions of the ladder and overlapping/securing upon the blind platform  14 ) and an optional seat portion  20  (this further being located at an upper end of the ladder stand and securing to an elevated location of a tree or pole (representatively illustrated at  22 ) by such as a circumference extending band, strap or bar (at  24 ). Although not clearly illustrated, it is further envisioned and understood that additional straps, bands, ropes and like can be provided for securing any portion of the assembly, including the seat or other location of the ladder platform, to the elevated location of the tree or pole. 
         [0031]    Both the platform  14  and associated frame  12 , as will be described in subsequent detail, can be constructed of various materials, not limited to steel, aluminum, fiberglass, or forms of high strength plastics, and given that they adhere to the dynamic and structural integrity requirements of the design. As best shown in each of  FIGS. 1 ,  2 ,  3 ,  12  and  13 , the platform  14  according to a first preferred embodiment is collapsible with threaded connections established between a single cross over beam  26  and a pair of crosswise extending and end connected support arms  28  and  30 . 
         [0032]    The exploded views of  FIGS. 2 and 15  each illustrate a pair of angled brackets  32  and  34  associated with opposite ends of the main cross over beam  26 . Mating and aligning interiorly threaded apertures are established between the brackets  32  and  34  and (central) mounting locations associated with each of the end connected support arms  28  and  30  (see apertures  36  and  38  in  FIG. 2 ), through which are inserted connecting knobs with threaded shafts (at  40  and  42 ) to assemble and secure together the beam  26  and support arms  28  and  30 . This allows the platform to be broken down for improved storage or transport, such as into and out of a wooded area. Additionally, providing a more compact design improves both manufacturing and packaging aspects of the invention. 
         [0033]    A pair of adjustable clamps, see at  44  and  46 , area seated within extending and end disposed channels  48  and  50  defined in the main cross over beam  26 . A further pair of underside engaged and interiorly threaded nuts (see knob shaped articles at  52  and  54 ) are provided and are selectively tightened in a rotated fashion with portions of the clamps  44  and  46  which extend through the linear channels  48  and  50 , this in order to reposition laterally (inward/outward) the locations of the upper hook shaped ends of the clamps  44  and  46  in order to secure such as side locations of the ladder platform  18  which is overlapping supported upon the main assembleable platform  14 . 
         [0034]    The configuration of the laterally adjustable clamps provides adaptability between multiple sized tree stand or ladder stand platforms. The invention contemplates an upper hook shaped portion associated with each clamp sliding in and out along the cross over beam  26  of the blind&#39;s platform, and such that the hook portions are slid into required positions to allow attachment of associated side walls of the stand platform  18 , and by which the upper hook shaped end of each of the clamp overhangs associated side walls of the stand platform  18 . Once the hooks are connected to the stand&#39;s platform, the hooks get fastened down (again via the threaded and underside engaged knobs  52  and  54 ), thereby drawing the platform  14  tight to the ladder stand platform  18  (see again  FIGS. 1 and 3 ). This provides the secure fit between the stand and blind platforms. After completing this step, the blind cover can then be installed onto the blind platform. 
         [0035]      FIG. 14  is a perspective view of an alternate variant of collapsible platform with a pair of cross over beams  56  and  58  interconnecting a pair of end connected support arms  60  and  62 . In the variant of  FIG. 14 , pairs of clamps  64  &amp;  66  and  68  &amp;  70  are mounted within associated and linear extending channels  72  &amp;  74  and  76  and  78  (these being capable of securing to multiple locations associated with such as a ladder stand platform as shown at  18 ). Connecting knobs/shafts are again shown at  40  and  42 , each of these defining an aligning mounting location (via associated apertures) established between a selected one of the cross over beams  56  and  58  and support arms  60  and  62 . Underside and threadably engaged knob shaped nuts are again provided (see at  80 - 86 ) and selectively engage and tighten underside protruding locations of the clamps  64 - 70 , respectively. 
         [0036]    The configuration of the cross over beams and end support arms in  FIG. 14  is further modified, such as by making each of the support arms  60  and  62  exhibit an “L” angled profile, and so that the elements inter-assemble in the manner shown. Associated mounting support fixtures, at  88 ,  90 ,  92  and  94  are affixed or integrally formed with associated edge locations of each of the end support arms, such as those shown at  28  &amp;  30  in  FIG. 13 . Modified support fixtures are further shown at  96 ,  98 ,  100  and  102  for end support arms  60  and  62  associated with the variant of  FIG. 14 . 
         [0037]    The frame (previously generally referenced at  12 ) includes a plurality of poles  104 ,  106 ,  108  and  110 . Each of the poles exhibits and elongate and multi-bend configuration (e.g. each pole being uniquely configured in a multiple successive angled fashion between first bottom and second top ends), and which eliminates the need for assembling shorter poles together prior to setting up in the field. The preformed poles  104 - 110 , upon assembly, serve as a frame superstructure to provide support for the cover  10  (as will again be described in further detail with reference to  FIGS. 4-6 ). 
         [0038]    A corresponding bottom end of each pole  104 - 110  is assembled with the platform by being inserted into associated mounting support fixtures  88 - 94 . The poles can likewise be constructed of various materials including steel, aluminum, fiberglass, or forms of high strength plastics, as long as they meet the structural and dynamic integrity requirements of the design. 
         [0039]    As best shown in each of  FIGS. 2 and 9 , the pole constructed superstructure frame further exhibits an upper support assembly including a top plate  112  and a spaced apart lower support plate  114 , and between which are sandwich received in pivotally permitting fashion angled upper end locations associated with each of the poles  104 - 110  (these further being illustrated at  116  and  118  for forward pivotally disposed poles  104  and  110  and further at  120  and  122  for rearward pivotally disposed poles  106  and  108 ). 
         [0040]    The plates  112  and  114  each include mating apertured locations (see as best shown by individual pluralities of mating apertures  124  and  126  in the enlarged illustration of  FIG. 9 ) for receiving upper configured ends  116 ,  118 ,  120  and  122  associated with each of the poles. As best seen in  FIG. 7 , the configured pole ends  116 - 122  each also include an aperture and which, upon aligning with the aperture patterns  124  and  126 , receive individual tightening bolts and nuts (see at  128  and  130  in  FIG. 2 ). In this fashion, the poles may be rotatably converted between expanded use ( FIG. 1 ) and collapsed storage ( FIG. 10 ) positions and, by virtue of the offset configuration of a subset plurality of rear end attachment portions  120  and  122  associated with a like subset pair of poles  106  and  108 , establishes a minimized gap between the collapsed poles, this reducing flex or bend of the poles during handling or transport when in the collapsed position. 
         [0041]    Referencing again  FIG. 1 , an explanation of an existing tree stand assembly, defined herein as being used in combination with the adaptable blind of the present invention, includes the ladder stand  16 , as customarily known, progressively angled at its upper end and terminating in a generally horizontal and “U” shape (see again at  24 ) which encircles the diameter of such as a tree  22  or other vertically extending spar or support (e.g. a utility pole or the like). It is further worth pointing out that the upper end support can be either mechanically secured and/or integrally formed with the ladder stand  16  and define the only contact point to the tree or pole  22 , and further such as upon being assembled or displaced around the circumference thereof. 
         [0042]    In an elevated application such as shown in  FIG. 1 , the ladder  16  includes a platform  18  which is again secured to the main platform in the manner previously illustrated. As also shown in  FIG. 1 , the seat  20  includes a back and bottom, these integrally configured with an upper end of the ladder stand  16 . A forward cross bar, see at  132  in  FIG. 1 , can be provided for safety restraint of the user when used in an elevated and tree supported application. A ground supported variation of the adaptable hunting blind is also contemplated and does not require use of the ladder stand  16  components. 
         [0043]      FIG. 11  is a further illustration showing a variation of a platform according to the present invention in combination with a known tree stand design. In particular, a variation of a standing platform  18 ′ with modified seat  20 ′ is provided and which is supported upon the platform design of  FIG. 14 . The version of  FIG. 11  is similar to that illustrated in  FIG. 1 , and by which the strap, band or the like (not shown) can be provided for securing the standing platform to an elevated tree or pole location. 
         [0044]    Referring now to  FIGS. 4-6 , a succession of front, rear and left/right side views are shown respectively of the covering material  10  associated with the collapsible superstructure. In a preferred application, the cover  10  can exhibit such as a camouflage pattern (see at  11  in  FIG. 4 ) and consists of four sides, including front, left, right, and back interconnected sides. As shown in  FIG. 4 , the front side has a doorway opening, see zipper  134 , for entry into the blind, the configuration of the doorway opening capable of being utilized in combination with the ladder stand  16 . It is also noted, in the instance of the tree stand being mounted at the base of the tree for hunting on the ground, a user can enter the blind from the front as well. The zippered opening  134  is provided separately from a window  136 , this also capable of being zippered, for viewing the outside environment while inside the blind, as well as for permitting access for a long barrel firearm or arrow in the instance of hunting. 
         [0045]    Referencing further the rear side illustration of  FIG. 5 , exhibited are a pair of window openings  138  and  140  (these being positioned such as off to each side of the rear and in order to take into account the diameter of the pole or tree which is usually located to the center of the cover in an elevated mount configuration), this arrangement enabling the user to view outside while seated within the blind. The back side also includes a vertically extending upper zippered (or flap) portion  142 , and which zips up to enclose the cover, and such as after being assembled onto the platform  14 . A lower portion of the back side may further wrap around the tree stand and does not require a zipper. The side illustration of  FIG. 6  is a representative right side view, a corresponding left side view being a substantially mirrored opposite, and by which a further zippered window, at  144 , is provided. 
         [0046]    The cover  10  includes straps (now shown) which can be sewn in along the edges of the walls and which are used to tie around the frame constructing poles  104 - 110 , thereby securing the cover  10  to the pole frame. Upon removing the poles from the platform frame  14 , the cover  10  and poles can optionally stay connected to each other, with the poles collapsed to the position shown at  FIG. 10  for ease of transportation, such as in and out of the woods. 
         [0047]    An associated assembly method contemplates running a cable (not shown) through the end of each pole, the closed loop configuration achieved being in order to prevent the poles from separating during use Reference is also made to  FIG. 2  and which again illustrates similar poles in an assembled configuration. 
         [0048]    Novel aspects of the present invention include and are not limited to: 
         [0049]    providing total concealment to game and protection against weather; 
         [0050]    connecting to existing tree stands and ladder stands, such that no special stand is required to be used with the assembly; 
         [0051]    accommodating reasonably designed commercial tree and ladder stands; 
         [0052]    permitting user entry and exit from the front of the blind while it is assembled to the ladder stand or a tree stand being mounted at the base of a tree for hunting on the ground; 
         [0053]    incorporating an adjuster mechanism consisting of adjustable hooks that slide up and down the cross members of the tree blind&#39;s platform, allowing use with multiple platform sizes and widths; 
         [0054]    designing of the blind is designed to be easily folded up for carrying in and out of the woods with ease, while the platform can remain on the tree or ladder stand; 
         [0055]    providing the poles in a pre-formed state, which eliminates any need for assembling shorter poles together prior to setting up in the field; 
         [0056]    optimizing the number of poles required to firmly hold up the cover around the tree stand; 
         [0057]    pre-formed poles designed to provide space where space is needed inside the blind, with the bottom of the poles tapering in toward the center of the blind, reducing the size requirements of the blind&#39;s platform; and 
         [0058]    designing the platform such that the user can climb into and out of ladder stand without having to climb thru a hole in the cover, or without having to climb over a cross member in the platform. 
         [0059]    Having described my invention, other and additional preferred embodiment will become apparent to those skilled in the art to which it pertains and without deviating from the scope of the appended claims:
