## Background
RELATED APPLICATION
This is a continuation-in-part of prior application Ser. No. 13/485,270, filed May 31, 2012, entitled GROUND BLIND, which is hereby incorporated in its entirety by reference herein.


BACKGROUND
1. Field
The present invention relates generally to erected enclosures and shelters. More specifically, embodiments of the present invention concern a ground blind operable to be used by one or more hunters and operable to be selectively erected and collapsed.
2. Discussion of Prior Art
Various types of prior art collapsible enclosures and shelters have been used for a wide range of outdoor applications such as camping, hunting, and storage. For instance, conventional collapsible tents tend to be very lightweight and have long been used by campers, hunters, and hikers. Some prior art collapsible enclosures are also designed for use as a hunting blind. Such conventional blinds have different shapes and sizes and are also operable to be either erected or collapsed in a matter of seconds.
Conventional collapsible enclosures and shelters have certain deficiencies. For those that are very light and portable, such structures are also known to lack rigidity when erected. Consequently, these enclosures perform poorly in adverse weather conditions such as high winds, rain, and heavy snow. At the same time, larger conventional enclosures and shelters are known to be heavy and bulky, are difficult for one or two people to quickly erect or collapse, and are difficult for one or two people to manually transport. In particular, larger prior art hunting blinds tend to be constructed of rigid building materials so that the blind is highly weather resistant but difficult for a person to transport without the assistance of a powered vehicle.
SUMMARY
The following brief summary is provided to indicate the nature of the subject matter disclosed herein. While certain aspects of the present invention are described below, the summary is not intended to limit the scope of the present invention.
Embodiments of the present invention provide a ground blind that does not suffer from the problems and limitations of the prior art enclosures set forth above.
A first aspect of the present invention concerns a collapsible enclosure that broadly includes a frame assembly and an outer shell. The frame assembly extends between and presents opposite frame ends. The frame assembly includes frame sections that each at least partly define a respective framed area. The frame sections are attached in series with one another to extend between the frame ends and present an adjacent pair of frame sections. The adjacent pair of frame sections are shiftably attached to one another and shiftable into and out of a collapsed position where the adjacent pair of frame sections extend alongside one another. The outer shell is removably attachable to the frame assembly so that the frame assembly and outer shell cooperatively define an interior space. The outer shell includes a shell segment removably attachable to a corresponding frame section, with the shell segment spanning the framed area of the corresponding frame section when attached thereto.
A second aspect of the present invention concerns a collapsible enclosure that broadly includes a frame assembly and an outer shell. The frame assembly extends between and presents opposite frame ends. The outer shell is attachable to the frame assembly so that the frame assembly and outer shell cooperatively define an interior space. The frame assembly includes frame sections shiftably attached in series with one another to extend between the frame ends, with the frame sections being erectable to cooperatively receive the outer shell along a frame assembly area. The outer shell includes shell segments removably attachable relative to the frame assembly when the frame assembly is erected to present an adjacent pair of shell segments. The adjacent pair of shell segments overlap one another to cooperatively span the frame assembly area when attached to the frame assembly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Turning initially to FIGS. 1-3, a ground blind 20 is constructed in accordance with a preferred embodiment of the present invention. The ground blind 20 preferably provides a semi-permanent camouflaged enclosure for one or more hunters. By referring to the ground blind 20 as semi-permanent, it will be understood that the ground blind 20 is preferably operable to be setup in an erected configuration or taken down and placed in a collapsed configuration in a matter of minutes by one or two hunters, as will be discussed further. In this manner, the ground blind 20 resists excessive wind, rain, or snow while being relatively portable.
The ground blind 20 is preferably used as a camouflaged shelter by hunters. For instance, the ground blind 20 could be used to hunt deer, turkey, or geese. To this end, the cover of the blind 20 presents an exterior surface with conventional camouflage graphics (not shown). Additionally, the ground blind 20 also preferably has a generally cylindrical shape so that the blind is sized and shaped to resemble the size and shape of a conventional round hay bale. Thus, with camouflage graphics resembling hay, the blind looks similar to a round hay bale. The illustrated blind 20 is preferably secured to the ground with an anchoring assembly including a plurality of conventional lines L and anchors An, although other anchoring structures could be used, e.g., depending upon the size and shape of the blind 20.
One of ordinary skill in the art will appreciate that the cover could have alternative graphics, such as alternative camouflage graphics suited for blending in with the adjacent environment, without departing from the scope of the present invention. While the blind 20 preferably has the cylindrical shape when erected, it is within the ambit of the present invention where the blind 20 has an alternative shape. Again, the blind 20 is preferred for use as a camouflaged shelter. However, it will appreciated that the blind 20 could have various other uses as an enclosure or shelter. For instance, the blind 20 could be used to provide an enclosure for covered storage. The blind 20 broadly includes a frame assembly 22 and a cover assembly 24.
Turning to FIGS. 10-18, the illustrated frame assembly 22 is a preferred support structure for blind 20. The frame assembly 22 preferably includes an articulated frame 26, front and back end frames 28,30, and a pair of elongated upper support rods 32. As will be discussed in greater detail, the articulated frame 26 is efficiently shiftable between erected and collapsed configurations. The articulated frame 26 preferably includes a plurality of tubular frame sections 34a-h and hinge devices 36 that interconnect adjacent pairs of the frame sections 34.
The tubular frame sections 34 each preferably include metal peripheral tubes 38 and metal tube connectors 40 (see FIGS. 12 and 18). The tube connectors 40 preferably are made of solid metal rod with opposite ends that project from a bend. Each pair of adjacent tubes 38 and the respective tube connector 40 are preferably welded to each other so that the frame section 34 is substantially rigid and unitary. The tubes 38 are preferably made from one-half inch nominal diameter steel tubing, although other tubing sizes could be used without departing from the scope of the present invention. While the tubes 38 and tube connectors 40 are preferably metal, the principles of the present invention are applicable where the tubes 38 and tube connectors 40 are made from other materials, such as a synthetic resin material. The articulated frame 26 preferably has a wear-resistant outer coating, such as a powder-coated finish or similar baked finish.
The illustrated tubular frame sections 34 each preferably have the peripheral tubes 38 arranged in a generally rectangular shape having a section width dimension W, with the peripheral tubes 38 and tube connectors 40 defining a continuous outer margin of a framed area F1 (see FIGS. 11 and 18). However, as will be explained in greater detail, the frame sections 34 could be alternatively shaped to provide the frame assembly 22 without departing from the scope of the present invention. For instance, one or more frame sections 34 could have different width dimensions W and/or could have different values of framed area F1.
Turning to FIG. 13, the hinge devices 36 each preferably include a pair of sleeves 42 fixed alongside one another so that the sleeves 42 present axes A that are substantially parallel to one another. As will be discussed, the sleeves 42 are preferably fixed so that the axes A define a hinge spacing dimension D1 that is about equal to or greater than the diameter dimension of the peripheral tubes 38. Preferably, the sleeves 42 comprise metal tubes, with the sleeves 42 being welded to each other. The hinge devices 36 also preferably include a pair of bushings 44 that are inserted and frictionally secured within the sleeves 42. The bushings 44 are preferably made of nylon, but could include other materials, such as ultra-high-molecular-weight (UHMW) polyethylene, another type of synthetic resin, or a relatively soft metal such as brass. The bushings 44 each present a bore that rotatably receives a corresponding one of the frame sections 34. Preferably, the bushings 44 and respective tubes 38 rotatably and frictionally engage one another so that frictional engagement between the tube 38 and bushing 44 restricts relative rotation therebetween. In this manner, each hinge device 36 interconnects a respective pair of adjacent frame sections 34 and serves to restrict relative rotation between the frame sections 34.
Turning to FIGS. 10-15 and 18, each pair of adjacent frame sections 34 is preferably interconnected by three of the hinge devices 36 so that the adjacent frame sections 34 and each hinge device 36 cooperatively form a pair of parallel hinges 46 that provide pivot joints permitting relative rotation about the parallel sleeve axes A. Of course, it will be appreciated that an alternative number of hinge devices 36 could be employed to provide suitable interconnection of the adjacent frame sections 34. Also, while the hinges 46 provide preferred pivot joints, the principles of the present invention are applicable where the pivot joints connecting each pair of adjacent frame sections 34 have an alternative construction.
Again, the sleeves 42 are preferably fixed so that the axes A define a hinge spacing dimension D1 that is about equal to or greater than the diameter dimension of the metal tubes. In this manner, adjacent frame sections 34 can preferably be shifted into and out of a folded position where the framed areas F1 of the adjacent frame sections 34 are positioned adjacent one another (see FIG. 18). Each frame section 34 preferably defines a plane P that extends through the longitudinal axes of the associated tubes 38. Preferably, the frame sections 34 and hinge devices 36 are constructed so that the planes P of adjacent frame sections 34 are substantially parallel with one another in the folded position (see FIGS. 12 and 18). However, for some aspects of the present invention, the planes P could define a slightly oblique angle in the folded position.
As will be discussed, the articulated frame 26 is preferably configured so that the hinge devices 36 allow the articulated frame 26 to assume a very compact shape in the collapsed configuration, as will be explained below. In the erected configuration, the articulated frame 26 preferably provides support for the top and opposite sides of the blind 20 and defines the shape of a covered interior space S.
Turning again to FIGS. 10-18, the end frames 28,30 preferably include tubular end frame sections 48,50, hinge devices 36 that interconnect the end frame sections 48,50, and connectors 52. The end frames 28,30 are also shiftable between erected and collapsed configurations.
Similar to frame sections 34, end frame sections 48,50 each preferably include metal peripheral tubes 54 and metal tube connectors 56. The end frame sections 48 also preferably include metal intermediate tubes 58 that extend laterally to be fixed to and thereby interconnect opposite peripheral tubes 54 (see FIG. 11). The end frame section 50 preferably does not include metal intermediate tubes so that the end frame section can accommodate a door for ingress and egress relative to the blind 20.
Again, the tube connectors 56 preferably are made of solid metal rod with opposite ends that project from a bend. The tubes 58 are preferably made from one-half inch nominal diameter steel tubing, although other tubing sizes could be used without departing from the scope of the present invention. Each pair of adjacent peripheral tubes 54 and the respective tube connector 56 are preferably welded to each other so that the frame section 48,50 is substantially rigid and unitary, although the tubes 54 and tube connectors 56 could be made from other materials, such as a synthetic resin material. The end frames 28,30 also preferably have a wear-resistant outer coating, such as a powder-coated finish or similar baked-on finish.
The end frame sections 48,50 preferably have the illustrated six-sided shape formed by peripheral tubes 54 that define a continuous outer margin of a framed area F2 (see FIG. 18). However, the end frame sections 48,50 could be alternatively shaped to provide the end frames 28,30 without departing from the scope of the present invention.
Each pair of end frame sections 48,50 is preferably interconnected by three of the hinge devices 36 so that the adjacent frame sections 48,50 and each hinge device 36 cooperatively form a pair of parallel hinges 46 that permit relative rotation about the parallel sleeve axes A. Of course, it will be appreciated that an alternative number of hinge devices 36 could be employed to provide suitable interconnection of the adjacent frame sections 48,50.
Turning to FIGS. 12 and 15, each connector 52 is preferably a unitary clamp and includes a central body 60 and opposite pairs of tabs 62 that present open ends of the connector 52. The tabs 62 can flex relative to the body 60, with the connector 52 presenting parallel bores 64. The bores 64 have axes A2 that are parallel and are positioned apart to define an opening spacing dimension D2. In the illustrated embodiment, the opening spacing dimension D2 is substantially the same as the hinge spacing dimension D1, although the opening spacing dimension D2 could be alternatively sized. The connectors 52 are preferably removably attached to the respective end frame section 48,50, with the tabs 62 of connectors 52 grabbing and holding the respective end frame section. However, it is within the scope of the present invention where the connectors 52 are captive, i.e., permanently attached, on either the respective end frame section 48,50 or the articulated frame 26.
The illustrated end frames 28,30 are removably attached along respective sides of the articulated frame 26 with the connectors 52, with the tabs 62 of connectors 52 grabbing and holding the articulated frame 26 so that the frame assembly 22 resists flexing movement and is preferably self-supporting. The frames 26,28,30 are preferably removably attached to one another with connectors 52 that provide tool-less connections. Thus, the frame assembly 22 can preferably be shifted between the collapsed and erected configurations without the use of tools. While the end frames 28,30 are preferably removably attached to articulated frame 26, a permanently-attached end frame structure, such as that shown in a subsequent embodiment, could be permanently attached to the articulated frame 26 without departing from the scope of the present invention.
Turning to FIGS. 11, 12, and 14, the rods 32 each include multiple elongated rod segments 66 that each comprise a flexible tube that flexes elastically when attached to the frame. Preferably, the rod segments 66 comprises fiberglass tubes, although the rod segments 66 could include other materials without departing from the scope of the present invention. The rods 32 also include sleeves 68 and an elongated elastic cord (not shown). Each pair of adjacent rod segments 66 are removably interconnected by one of the sleeves 68 when the rod 32 is assembled. The cord is preferably attached to opposite ends of the rod 32 and extends the length of the rod 32 through the rod segments 66 and sleeves 68. Also, the cord is preferably under tension when the rod 32 is assembled to urge the pairs of adjacent rod segments 66 to remain interconnected.
The rods 32 further include a pair of metal end connectors 70 that present opposite tabs 72. The end connectors 70 are attached to opposite ends of the rod 32, with the tabs 72 serving to grab a respective pair of frame tubes. The rods 32 are attached to and extend along the length of the articulated frame 26 to interconnect multiple frame sections 34. In particular, the rods 32 preferably extend along frame sections 34c,d,e,f to support the cover assembly 24 along the top of the blind 20 (see FIG. 11). The rods 32 extend along a curved path that extends at least partly out of planes P of the frame sections 34c,d,e,f so that the rods 32 resist sagging of the top of the main cover 74. It will be appreciated that the rods 32 could have an alternative length so as to extend along more or less of the frame sections 34 without departing from the scope of the present invention.
Turning to FIGS. 1-10, the cover assembly 24 preferably provides a weather resistant cover for the frame assembly 22 so that the blind 20 presents the covered interior space S. The cover assembly 24 preferably includes a main cover 74, a fixed end cover 76, and a removable end cover 78, with the end covers 76,78 being attached to the main cover 74, as will be discussed. The main cover 74 includes an elongated central section 80, side and end margins 82,84, fabric strips 86, zippers 88 (shown schematically), and fabric hook assemblies 90. The central section 80 extends continuously between opposite end margins 84 and comprises a fabric sheet that presents interior and exterior surfaces 92a,b. The central section 80 also presents multiple slots 96,98 that define movable flaps 100,102.
The zippers 88 are conventional and are attached to the central section 80 along the slots 96,98 so that the flaps 100,102 can be selectively opened and closed. While the zippers 88 are preferred, it is within the ambit of the present where an alternative fastener arrangement is used to hold each flap 100,102 open or closed along the length of the respective slot 96,98.
The fabric hook assemblies 90 each include a hook 104 and a loop 106 (see FIGS. 9a and 9b). The hooks 104 are attached to flaps 100 and the loops 106 are attached to the central section 80 on the other side of slots 96. Thus, the hooks 104 can be removably connected to corresponding loops 106 to selectively hold the flap 100 upright. Alternatively, the hook assemblies 90 can be selectively disconnected to permit the flap 100 to drop into a hanging position.
Again, the main cover 74 includes side margins 82 and end margins 84. The end margins 84 preferably include elongated hook and loop fasteners 108,110 sewn onto the fabric at spaced apart positions along the end margins 84 (see FIG. 3a). The fasteners 108,110 are removably attached to one another so that the end margins 84 are each formed into a loop.
The fabric strips 86 are attached to the exterior surface 92b of the central section and extend laterally. The strips 86 are preferably sewn onto the central section 80 to form a plurality of laterally spaced loops 112 that provide brush connectors operable to receive and hold pieces of brush.
The fixed end cover 76 preferably includes a unitary main section 114, bottom sections 116, zippers 118, and fabric strips 120 (see FIG. 2). The main section 114 preferably comprises a fabric sheet that presents interior and exterior surfaces 122a,b, a continuous outer margin, and slots 124 that define movable flaps 126.
The bottom sections 116 are mounted along the bottom margin of the main section 114 and preferably include elongated hook and loop fasteners (not shown). The fasteners are sewn along the bottom margin and are removably attached to one another so that the bottom sections 116 form a loop.
The zippers 118 are conventional and are attached to the main section 114 along the slots 124 so that the flaps 126 can be selectively opened and closed. While the zippers 118 are preferred, it is within the ambit of the present where an alternative fastener is used to hold each flap 126 open or closed along the length of the respective slot 124.
The fabric strips 120 are attached to the exterior surface 122b of the main section 114 and extend laterally. The strips 120 are preferably sewn onto the main section to form a plurality of laterally spaced loops 128 that provide brush connectors operable to receive and hold pieces of brush.
The fixed end cover 76 is preferably sewn to the main cover 74 with a continuous line of stitches along the side of the main cover. However, the principles of the present invention are applicable where the end cover 76 and main cover 74 are fixed to each other with alternative fasteners. Also, while the end cover 76 is preferably fixed to the main cover 74, it is within the ambit of the present invention where end cover 76 is also removable such that both end covers 76,78 can be selectively attached to and removed from the main cover 74.
The combination of the main cover 74 and the fixed end cover 76 can be secured onto the frame assembly 22. In particular, the covers 74,76 are preferably positioned with the interior surfaces 93a, 122a against corresponding portions of the frame. The end margins 84 are then folded around the ends of the articulated frame 26 so that the covers 74,76 are secured to the frame, preferably with the covers 74,76 being under some tension so as to conform along the planar shapes of the frame sections.
The removable end cover 78 preferably includes a unitary main section 130, bottom sections 132, and zippers 134. The main section 130 preferably comprises a fabric sheet that presents interior and exterior surfaces 136a,b, a continuous outer margin, and slots 138,140 that define movable flaps 142 and a door 144.
The bottom sections 132 are mounted along the bottom margin of the main section and preferably include elongated hook and loop fasteners (not shown). The fasteners are sewn along the bottom margin and are removably attached to one another so that the bottom sections 132 form a loop.
The zippers 134 are conventional and are attached to the main section 130 along the slots 138,140 so that the flaps 142 and door 144 can be selectively opened and closed. While the zippers 134 are preferred, it is within the ambit of the present where an alternative fastener is used to hold each flap 142 and door 144 open or closed along the length of the respective slot 138,140.
The removable end cover 78 is preferably removably attached to the main cover 74 with a continuous zipper 146 that extends along the side of the main cover 74 (see FIG. 10). However, the principles of the present invention are applicable where the end cover 78 and main cover 74 are removably attached to each other with alternative fasteners. Also, while the end cover 78 is preferably removably attached to the main cover 74, it is within the ambit of the present invention where end cover 78 is fixed to the main cover 74.
While the cover assembly 24 preferably includes the end cover 78 being removable from main cover 74, it is within the scope of the present invention where the cover assembly 24 comprises a unitary cover construction that is not separable into multiple sections. Also, while the illustrated cover assembly 24 preferably includes end covers 76,78, it is within the scope of the present invention where end covers 76,78 are not included.
The illustrated cover assembly 24 is preferably constructed of a pliable fabric. The pliable fabric is also preferably made from synthetic resin fibers, although natural fibers could be used without departing from the scope of the present invention. Also, for some aspects of the present invention, the cover assembly 24 could be provided by a non-fabric construction, such as a molded synthetic resin construction (e.g., where the cover is formed by thermal molding, rotomolding, or injection molding). In one such embodiment, the cover assembly could include a plurality of molded panels that are attached to the frame assembly and overlap one another to cooperatively provide a continuous, weather-resistant shell for the ground blind. For instance, molded panels could be removably attached to corresponding frame sections 34 so that each of the attached panels spans the framed area of the corresponding frame section 34. Also, each adjacent pair of attached molded panels could overlap one another when the ground blind is erected so that the attached panels shed rain, snow, and other external elements. Yet further, the shell could include molded end panels that are removably attached to corresponding end frame sections 48,50 so that each of the attached molded end panels spans the framed area of the corresponding end frame section. Each pair of attached molded end panels could also overlap one another as well as adjacent molded panels that are attached to frame sections 34. In this manner, when the blind 20 is erected, the entire frame structure is substantially cooperatively spanned by the molded panels attached to frame sections 34,48,50 so as to form the continuous shell. It will be appreciated that such an alternative cover could include various doors and windows that are selectively opened and closed to permit desired use of the blind 20.
In referring to the ground blind 20 as a semi-permanent construction, it will be understood that the ground blind 20 is preferably operable to be setup or taken down in a time that ranges from about one (1) minute to about ten (10) minutes and, more preferably, ranges from about three (3) to four (4) minutes. Also, the semi-permanent blind 20 is preferably operable to be setup or taken down in the above-referenced times by one or two people.
Yet further, to provide a semi-permanent structure that is portable, the blind 20 preferably has a size and weight such that the blind can be transported manually by one or two people. The ground blind 20 preferably has a weight that ranges from about (20) pounds to about one hundred (100) pounds and, more preferably, is about seventy (70) pounds.
In the erected configuration, the blind 20 is preferably dimensioned to accommodate at least two users. Preferably, the blind 20 has a height dimension that ranges from about sixty (60) inches to about eighty (80) inches and, more preferably, is about seventy-three (73) inches. The width dimension W preferably ranges from about sixty (60) inches to about eighty (80) inches and, more preferably, is about seventy-two (72) inches. Also, the blind 20 presents a maximum lateral dimension M that ranges from sixty (60) inches to about eighty (80) inches and, more preferably, is about seventy-four (74) inches (see FIG. 10).
In the collapsed configuration, the articulated frame 26 preferably presents the width dimension W, a collapsed lateral dimension C, and a minimum collapsed thickness dimension (see FIG. 18). The collapsed lateral dimension C preferably ranges from about twenty (20) inches to about thirty (30) inches and, more preferably, is about twenty-four (24) inches. The minimum collapsed thickness dimension preferably ranges from about four (4) inches to about twelve (12) inches.
Turning to FIGS. 11 and 18, the articulated frame 26 is preferably shiftable between the collapsed and erected configurations. Again, in the erected configuration, the articulated frame 26 preferably takes on a generally cylindrical shape where the width dimension W is substantially constant along the length of the articulated frame 26. Thus, the blind 20 is sized and shaped to resemble the size and shape of a conventional round hay bale. For some purposes, the articulated frame 26 in the erected configuration could have an alternative shape, e.g., a frustum, cone, pyramid, cuboid, or horizontal cylindrical segment. In the erected configuration, the frame sections are moved out of the folded positions so that the articulated frame 26 spans an erected area E along the bottom of the interior space S, with the erected area E preferably being greater than the framed area F1 (see FIG. 3).
In the collapsed configuration, the adjacent pairs of frame sections 34 are each preferably in the folded position. Furthermore, the frame sections 34, which are preferably connected in series with each other, are folded so that the frame sections 34 are preferably stacked in series with each other (see FIG. 18). In other words, where the frame sections 34 cooperatively present interior and exterior faces of the articulated frame 26, the articulated frame 26 is collapsed by folding the frame sections 34 in an alternating pattern. For instance, the articulated frame 26 is collapsed by folding first and second connected frame sections 34a,b so that the interior faces are facing one another, folding second and third connected frame sections 34b,c so that the exterior faces are facing one another, folding third and fourth connected frame sections 34c,d so that the interior faces are facing one another, etc.
Also, the planes P of the frame sections 34 are preferably substantially parallel to one another in the folded position. Furthermore, the framed areas F1 are preferably in substantial registry with one another. In this manner, it has been found that the articulated frame 26 assumes a very compact shape in the collapsed configuration. However, for some aspects of the present invention, the planes P of frame sections 34 could be in a nonparallel orientation relative to one another in the collapsed configuration. Also, the frame sections 34 could be out of registry in the collapsed configuration.
While the illustrated frame sections 34 preferably form the same rectangular shape, it is within the ambit of the present invention where the frame sections 34 share an alternative shape, such as a square, triangular, or trapezoidal frame shape. Also, while the frame sections 34 preferably share the same shape, the frame sections 34 could also have shapes different from one another, e.g., to provide a suitable shape for the ground blind 20.
Again, the frame assembly 22 preferably has removable end frames 28,30. However, the frame assembly 22 could also have an end frame structure permanently attached to the articulated frame 26. Furthermore, for some aspects of the present invention, the frame assembly 22 could be devoid of end frames 28,30 while still being self supporting and substantially rigid. For instance, the articulated frame 26 could include gussets to selectively secure adjacent frame sections 34 in the illustrated erected configuration while restricting relative pivotal movement therebetween. In another alternative consistent with the principles of the present invention, the frame sections 34 of the articulated frame 26 could share the same shape (e.g., triangular or trapezoidal) and be connected to one another in series so that the frame sections 34 assume an approximately pyramidal, conical, frusto-pyramidal, or frusto-conical shape when arranged in the erected configuration.
In use, the ground blind 20 is preferably erected by arranging the end frame 30 on the ground with the end frame sections unfolded. Then, the articulated frame 26 is preferably shifted from the collapsed configuration to the erected configuration by unfolding the frame sections 34 while the articulated frame 26 is supported with the side 82 along the ground. The unfolded articulated frame 26 is then attached to the unfolded end frame 30 with connectors 52.
The articulated and end frames 26,30 are then preferably rotated into an upright orientation. With the frames 26,30 in this upright orientation, the end frame 28 is preferably unfolded and attached to the articulated frame 26 along the side 82 with connectors 52. The rods 32 are then removably attached to the articulated frame 26 and preferably extend along frame sections 34c,d,e,f. 
The main cover 74 is then positioned in covering relationship with the articulated and end frames 26,30, with the end sections being folded over corresponding parts of the articulated and end frames 26,30 to secure the main cover 74. The removable end cover 78 is then secured to the main cover 74 with zipper 146 to be positioned in covering relationship with end frame 28. In the erected configuration, the illustrated blind 20 is preferably secured to the ground with the illustrated conventional lines L and anchors An, although other anchoring structures could be used.
The ground blind 20 is preferably collapsed by initially detaching the illustrated lines L and anchors An from the blind 20. Also, the removable end cover 78 can be unzipped and thereby preferably entirely detached from main cover 74. The main cover 74 and fixed end cover 76 can then be removed from the frame assembly 22.
With the cover assembly 24 removed, rods 32 can be detached and from articulated frame 26 and the frames 26,28,30 can be selectively detached from one another. For instance, one of the end frames 28,30 can be selectively detached with the frame assembly 22 in the upright position. The remainder of the frame assembly 22 can then be rotated so that the other end frame lies on the ground. The articulated frame 26 can then be detached from the other end frame. With the end frames 28,30 being detached, each end frame 28,30 can be shifted into the folded position (see FIG. 18). Also, the articulated frame 26 can be shifted into the folded position so that the frame sections 34 are stacked in series with one another.
Turning to FIGS. 19-41, alternative preferred embodiments of the present invention are depicted. For the sake of brevity, the remaining description will focus primarily on the differences of these alternative embodiments from the preferred embodiment described above.
Initially turning to FIG. 19-24, an alternative ground blind 200 is constructed in accordance with a second embodiment of the present invention. The alternative ground blind 200 includes an alternative frame assembly 202 and an alternative cover assembly 204.
The illustrated frame assembly 202 provides a preferred support structure for blind 200. The frame assembly 202 preferably includes an articulated frame 206, a pair of alternative end frame assemblies 208 supported at opposite ends of frame assembly 202, and elongated upper support rods 209. The articulated frame 206 preferably includes tubular frame sections 210a-h and hinge devices 212 that interconnect adjacent pairs of the frame sections 210.
Each of the end frame assemblies 208 preferably includes a set of end rods 214a-k, hinge elements 216 that pivotally support one end of the end rods 214, a hub assembly 218, and connectors 220.
End rods 214a-k each preferably comprise a unitary rod construction. Preferably, the end rods 214a-f are each pivotally attached at one end thereof to a respective one of the frame sections 210 one of the hinge elements 216. The other ends of rods 214a-f are preferably removably attached to hub assembly 218. Each hinge element 216 includes a tube section 222 and tabs 224, with a fastener 226 that extends through the tabs 224 (see FIGS. 21 and 22). Each tube section 222 is rotatably mounted on a corresponding one of the frame sections 210. The end rods 214a-f are attached to tabs 224 with fasteners 226 that extend through a hole (not shown) in the end rod 214a-f. 
The end rods 214g-j are pivotally attached to respective ones of end rods 214a-f with hinge elements 216. The end rods 214g-j are also removably attached to respective frame sections 210 with connectors 220. End rod 214k is pivotally attached to frame section 210a with a hinge element 216 and removably attached to frame section 210h with a connector 220.
The end rods 214 are each preferably pivotal between the collapsed configuration and the erected configuration. In the collapsed configuration, the end rods 214 are folded so that each end rod 214 extends along and is substantially parallel to the plane P of the frame section 210 that supports the end rod 214. Furthermore, the folded end rods 214 also preferably lie within the outermost margin of the frame section 210 that supports the end rod 214 in the collapsed configuration. In the erected configuration, the end rods 214 are moved into an erected position to cooperatively form an end frame structure that supports the articulated frame 206 (see FIG. 20).
The hub assembly 218 includes a base plate 228, a cover plate 230, a threaded bolt 232 fixed to the cover plate 230, and a threaded nut 234. The nut 234 is tethered to the base plate 228 and is removably threaded onto the bolt 232. The base plate 228 and cover plate 230 each present a plurality of slots 236 operable to receive respective end rods 214. The end rods 214 are preferably snapped into respective slots 236 so that the slots 236 restrict sliding movement of the end rods 214 out of the slots 236. The base plate 228 and cover plate 230 each also include an integral sleeve 237. The sleeve 237 of base plate 228 has end rod 214b secured thereto with a fastener. Sleeve 237 of cover plate 230 has end rod 214f secured thereto with a fastener.
The plates 228,230 are removably secured to each other by threading the nut 234 onto the bolt 232. Thus, the secured plates 228,230 cooperatively receive and secure the end rods 214a-f in the erected configuration and restrict relative movement of the end rods 214a-f. 
Turning to FIG. 19, the alternative cover assembly 204 preferably includes an alternative removable end cover 238 including a unitary main section 240, bottom sections 242, and zippers 244. The main section 240 preferably comprises a fabric sheet that presents interior and exterior surfaces, a continuous outer margin, and slots 246,248 that define movable flaps 250 and a door 252.
Alternative Collapsible Enclosure with Outer Shell
Turning to FIGS. 25-41, an alternative blind 300 is constructed in accordance with a third embodiment of the present invention. As with the previous embodiments, the blind 300 is preferably used as a camouflaged hunting shelter. However, the blind 300 can also be used as an enclosure for other purposes without departing from the scope of the present invention. For instance, the blind 300 could be employed as a storage enclosure. It is also within the ambit of the present invention where the blind 300 only partly encloses or covers the interior space within the blind 300. The alternative blind 300 preferably includes a frame assembly 302 and an outer shell 304.
The frame assembly 302 is similar to frame assembly 22 and includes an articulated frame 306, and front and back end frames 308,310. The articulated frame 306 preferably includes a plurality of tubular frame sections 312 and hinge devices 314 that interconnect adjacent pairs of the frame sections 312. The articulated frame 306 is preferably shiftable between erected and collapsed configurations.
The end frames 308,310 preferably include tubular end frame sections 316,318, hinge devices 320 (see FIG. 28) that interconnect the end frame sections 316,318, and double-ended connectors 322. The end frames 308,310 are also shiftable between erected and collapsed configurations.
However, it is within the ambit of the present invention where the blind 300 has an alternative frame assembly. For instance, one or more of the articulated frame 306 and the end frames 308,310 could be alternatively constructed. Yet further, for some aspects of the present invention, the blind 300 could be devoid of one or more of the articulated frame 306 and the end frames 308,310.
Turning to FIGS. 40 and 41, the connector 322 is similar to connector 52 and includes a central body 322a and pairs of tabs 322b that present a pair of bores 322c and opposite open faces 322d of the connector 322. The connector 322 defines a length dimension L1 and a width dimension W1. The length dimension L1 preferably ranges from about ten millimeters (10 mm) to about one hundred millimeters (100 mm) and, more preferably, is about fifty millimeters (50 mm). The width dimension W1 preferably ranges from about five millimeters (5 mm) to about fifty millimeters (50 mm) and, more preferably, is about thirty-eight millimeters (38 mm).
The illustrated connector 322 also defines a bore diameter dimension D1 and a face width dimension F1. The bore diameter dimension D preferably ranges from about four millimeters (4 mm) to about forty millimeters (40 mm) and, more preferably, is about eighteen and six-tenths millimeters (18.6 mm). The face width dimension F1 preferably ranges from about two millimeters (2 mm) to about thirty millimeters (30 mm) and, more preferably, is about twelve and two-thirds millimeters (12.66 mm). The tabs 322b each present a thickness dimension T that ranges from about one millimeter (1 mm) to about ten millimeters (10 mm) and, more preferably, is about three millimeters (3 mm). However, any of the above-referenced dimensions could fall outside of the indicated ranges without departing from the scope of the present invention.
Also, the face width dimension F1 of the connector 322 is preferably less than the bore diameter dimension D1 to provide frictional engagement between the connector 322 and the part of the frame assembly 302 received within the corresponding bore 322c. To provide such frictional engagement, a ratio of the face width dimension F1 to the bore diameter dimension D1 preferably ranges between about one half (0.5) to about nine-tenths (0.9) and, more preferably, is about two-thirds (0.66).
Turning to FIGS. 25-29, the illustrated outer shell 304 preferably serves as a cover for the blind 300. However, it is within the scope of the present invention where the outer shell 304 does not fully cover the interior space of the blind 300. The outer shell 304 preferably includes side shell segments 324 and end shell segments 326a,b. 
The end shell segment 326a preferably includes an end panel 328, door 330, a window cover 332, and single-ended connectors 334. Preferably, the end panel 328, door 330, and window cover 332 are each unitary. The end panel 328 preferably presents outer side margins 336 and a door opening 338 spaced from the side margins 336.
The door 330 is preferably sized to selectively cover the door opening 338 and presents outer side edges 340, raised window frames 342 spaced from the side edges 340, and a window opening 344 located within the window frame 342 (see FIGS. 25-27). The door 330 is swingably attached to the end panel 328 with a hinge 346 (see FIG. 27). The hinge 346 is secured in an upright position along the side edge 340 and along a corresponding portion of the end panel 328 so that the door 330 swings about an upright axis. The door 330 is preferably swingable between an open position where the door 330 permits user ingress and egress through the door opening 338 (see FIG. 27) and a closed position where the door 330 covers the door opening 338 (see FIG. 25). The door 330 is selectively held in the closed position with a door latch 348 that is operably attached to the door 330 (see FIGS. 25 and 27).
The window cover 332 is preferably sized to cover the window opening 344. The window cover 332 is swingably attached to the end panel 328 with a hinge 350 (see FIGS. 27 and 28). The hinge 350 is secured in a lateral position to corresponding portions of the window cover 332 and the end panel 328 so that the window cover 332 swings about a lateral axis. The window cover 332 is preferably swingable between an open position (not shown) where the window cover 332 permits the user to see at least partly through the window opening 344 and a closed position (see FIG. 25) where the window cover 332 covers the window opening 344. The window cover 332 is selectively held in the closed position with a window latch 352 that is pivotally attached to the door 330 adjacent the window opening 344.
Turning to FIGS. 37-39, each of the single-ended connectors 334 is preferably a unitary frictional clamp and includes a central body 354 and a pair of tabs 356 that present an open face 358 of the connector 334. The central body 354 presents a generally flat mounting surface 360 and threaded holes 361 to receive screws (not shown). The tabs 356 can flex relative to the body 354, with the connector 334 presenting a bore 362. The bore 362 has an axis A that is generally parallel to the mounting surface 360, with the mounting surface 360 and axis A spaced apart from one another (see FIG. 39).
The illustrated connector 334 defines a length dimension L2 and a width dimension W2. The length dimension L2 preferably ranges from about ten millimeters (10 mm) to about ninety millimeters (90 mm) and, more preferably, is about forty-five millimeters (45 mm). The width dimension W2 preferably ranges from about five millimeters (5 mm) to about fifty millimeters (50 mm) and, more preferably, is about twenty-four millimeters (24 mm).
The illustrated connector 334 also defines a bore diameter dimension D2 and a face width dimension F2 between the tabs 356. The bore diameter dimension D2 preferably ranges from about four millimeters (4 mm) to about forty millimeters (40 mm) and, more preferably, is about eighteen millimeters (18 mm). The face width dimension F2 preferably ranges from about two millimeters (2 mm) to about thirty millimeters (30 mm) and, more preferably, is about twelve and two-thirds millimeters (12.66 mm). However, any of the above-referenced dimensions could fall outside of the indicated ranges without departing from the scope of the present invention.
Also, the face width dimension F2 of the connector 334 is preferably less than the bore diameter dimension D2 to provide frictional engagement between the connector 334 and the part of the frame assembly 302 received within the bore 362. To provide such frictional engagement, a ratio of the face width dimension F2 to the bore diameter dimension D2 preferably ranges between about one half (0.5) to about nine-tenths (0.9) and, more preferably, is about two-thirds (0.66).
The connectors 334 are preferably molded from a synthetic resin material. More preferably, the connectors 334 are injection molded from an ultra-high molecular weight polyethylene (UHMW-PE) material. However, it is within the ambit of the present invention where the connectors 334 include one or more alternative materials and/or are manufactured using a different process. The connectors 334 are preferably attached to respective end shell segments 326a,b with threaded screws (not shown). However, it is within the ambit of the present invention where the connectors 334 are alternatively mounted to end shell segments 326a,b. 
Turning again to FIGS. 25-29, the end shell segments 326b are similar to end shell segment 326a, but do not include the door 330 or an end panel that presents the door opening 338. The end shell segments 326b each preferably include an end panel 364, window cover 332, and connectors 334. Preferably, the end panel 364 and window cover 332 are each unitary. The end panel 364 preferably presents side margins 336, raised window frames 342 spaced from the side margins 336, and a window opening 344 located within the window frame 342.
The window cover 332 is preferably sized to cover the window opening 344. The window cover 332 is swingably attached to the end panel 364 with a hinge 350. The hinge 350 is secured in a lateral position to corresponding portions of the window cover 332 and the end panel 364 so that the window cover 332 swings about a lateral axis. The window cover 332 is preferably swingable between an open position (not shown) where the window cover 332 permits the user to see at least partly through the window opening 344 and a closed position (see FIGS. 25 and 26) where the window cover 332 covers the window opening 344. The window cover 332 is selectively held in the closed position with a latch 352 that is pivotally attached to the end panel 364 adjacent the window opening 344.
The end panels 328,364, door 330, and window covers 332 are preferably molded from a synthetic resin material. More preferably, the end panels 328,364, door 330, and window covers 332 are preferably molded using a thermoforming process and are molded from acrylonitrile butadiene styrene (ABS). However, it is within the ambit of the present invention where these components include one or more other materials. Furthermore, the end panels 328,364, door 330, and window covers 332 could be manufactured by one or more alternative molding processes and/or other manufacturing processes.
The end panels 328,364 are each preferably forty and one-half inches (40.5′′) wide by seventy-eight and one-half inches (78.5′′) long. The door 330 is preferably twenty-nine and one-eighth inches (29.125′′) wide by sixty-seven and three-quarter inches (67.75′′) long. The window covers 332 are each preferably thirteen and three-quarters inches (13.75′′) wide by twenty-three and one-half inches (23.5′′) long. However, the end panels 328,364, door 330, and/or window covers 332 could have alternative dimensions without departing from the scope of the present invention.
When attached to the frame assembly 302, two end shell segments 326a,b are removably attached along the front end of the frame assembly 302, and two end shell segments 326b are removably attached along the back end of the frame assembly 302. The two end shell segments 326a,b along the front end of the frame assembly 302 are preferably arranged so that inboard ones of the side margins 336 overlap one another to form a vertical seam 365 (see FIG. 25). Similarly, the two end shell segments 326b along the back end of the frame assembly 302 are preferably arranged so that inboard ones of the side margins 336 overlap one another to form another vertical seam 365 (see FIG. 26). In this manner, the overlapping arrangement of end shell segments 326 restricts water and/or debris from entering the blind 300. However, the end shell segments 326 could be alternatively configured and/or arranged without departing from the scope of the present invention.
The end shell segments 326a,b are preferably removably attached to corresponding end frame sections 316,318 with the connectors 334. In particular, the connectors 334 are preferably frictionally attached to the respective end frame section 316,318, with the tabs 356 of connectors 334 grabbing and frictionally holding the respective end frame section 316,318. However, it is within the scope of the present invention where the connectors 334 are alternatively attached to the end frame sections 316,318.
When attached to the corresponding end frame sections 316,318, the end shell segments 326 preferably span the corresponding frame section 316,318 and cover the framed area of the corresponding frame section 316,318. However, it is within the ambit of the present invention where one or more of the end shell segments 326 do not cover the corresponding frame section 316,318.
For instance, in one alternative embodiment, one or more of the end shell segments 326 could be mounted within the corresponding frame section 316,318 while also spanning the corresponding frame section. In other words, the end shell segment 326 could be mounted within the framed area of the corresponding frame section 316,318.
Turning to FIGS. 25-36, the side shell segments 324a,b,c are preferably removably attached to the articulated frame 306. Each side shell segment 324a,b,c preferably includes a corresponding side panel 366a,b,c and connectors 334. Preferably, the side panels 366a,b,c are each unitary and present opposite angled side margins 368, opposite angled end margins 370, and raised window frames 372 spaced along the length of the side panel 366a,b,c. Furthermore, the illustrated side panels 366 all preferably have substantially the same size and shape, other than notched openings and window openings, as will be discussed. In this manner, each of the side panels 366 can be formed from the same mold using a thermoforming process. However, it is within the ambit of the present invention the side panels 366 are differently sized and/or shaped.
For the side panels 366, the connectors 334 are attached to an interior surface of the corresponding side panel 366a,b,c. As will be discussed, some of the side panels 366 present notched openings 374.
Turning to FIGS. 30-33, the side shell segments 324c each preferably include a side panel 366c, window covers 376, and connectors 334. Preferably, the side panels 366c and window covers 376 are each unitary. The side panels 366c each preferably present side margins 368, end margins 370, raised window frames 372 spaced along the length of the panel, and a window opening 378 located within each of the window frames 372. The upper one of the side margins 368 defines spaced apart notched openings 374. The notched openings 374 are preferably sized and positioned to receive a connector 334 attached to an adjacent side panel 366.
Each window cover 376 is preferably sized to cover the corresponding window opening 378. The window cover 376 is swingably attached to the side panel 366c with a hinge 380. The hinge 380 is attached in a lateral position to corresponding portions of the window cover 376 and the side panel 366c so that the window cover 376 swings about a lateral axis. The window cover 376 is preferably swingable between an open position where the window cover 376 permits the user to see at least partly through the window opening 378 (see FIGS. 30-33) and a closed position where the window cover 376 covers the window opening 378 (see FIG. 35). The window cover 376 is selectively held in the closed position with a latch 352 that is pivotally attached to the end panel 366c adjacent the window opening 378.
The connectors 334 are preferably attached to the side panels 366c along the end margins 370 and along a lower one of the side margins 368. Preferably, two connectors 334 are attached along the end margins 370 and three connectors 334 are attached along the lower side margin 368. Also, the area along the upper one of the side margins 368 is preferably devoid of connectors 334. It has been found that this arrangement of connectors 334 enables secure and reliable attachment of the side shell segments 324c to the articulated frame 306 without introducing excessive stresses into either the side panel 366c or the frame 306. However, for some aspects of the present invention, the side shell segments 324c could have an alternative connector arrangement (e.g., with an alternative number of connectors 334).
The side shell segment 324a is similar to side shell segment 324c but does not present any window openings 378 and does not include any window covers 376, hinges 380, or latches 352. Thus, the side panels 366a each preferably present side margins 368, end margins 370, and raised window frames 372 spaced along the length of the panel. The upper one of the side margins 368 defines notched openings 374 spaced along the length of the side panel 366a. The connectors 334 are preferably attached to the side panels 366a along the end margins 370 and along the lower one of the side margins 368. Preferably, the upper one of the side margins 368 is devoid of connectors 334. Again, it has been found that this arrangement of connectors 334 enables secure and reliable attachment of side shell segments 324a to the articulated frame 306 without introducing excessive stresses into either the side panel 366a or the frame 306. However, for some aspects of the present invention, the side shell segments 324a could also have an alternative connector arrangement.
The side shell segment 324b is similar to side shell segment 324a but does not present any notched openings 374 and includes connectors 334 along both end margins 370 and both side margins 368. Thus, the side shell segment 324b preferably includes a side panel 366b and connectors 334. The side shell segment 324b preferably has two connectors 334 attached along both end margins 370 and three connectors 334 attached along both side margins 368. As will be discussed, this arrangement permits the side shell segment 324b to operate as a cap by overlapping both of the adjacent side shell segments 324a. 
The connectors 334 are preferably attached to respective side panels 366 with threaded screws (not shown). However, it is within the ambit of the present invention where the connectors 334 are alternatively mounted to side panels 366.
The side panels 366 and window covers 376 are preferably molded from a synthetic resin material. More preferably, the side panels 366 and window covers 376 are preferably molded using a thermoforming process and are molded from acrylonitrile butadiene styrene (ABS). However, it is within the ambit of the present invention where these components include one or more other materials. Furthermore, the side panels 366 and window covers 376 could be manufactured by one or more alternative molding processes and/or other manufacturing processes.
The side panels 366 are each preferably twenty-nine and one-half inches (29.5′′) wide by seventy-three and one-eighth inches (73.125′′) long. The window covers 376 are each preferably thirteen and three-quarters inches (13.75′′) wide by twenty-one and one-half inches (21.5′′) long. However, the side panels 366 and/or window covers 376 could have alternative dimensions without departing from the scope of the present invention.
Initially, the side shell segments 324 are all preferably installed so that the end margins 370 overlap the corresponding end shell segments 326 to cooperatively form peripheral end seams 382. This overlapping construction restricts water and/or debris from entering the blind 300 through the end seam 382. However, the side shell and end shell segments 324,326 could be alternatively overlapped without departing from the scope of the present invention. For instance, the end shell segments 326 could have outer margins that overlap end margins 370 of the side shell segments 324.
The side shell segments 324 are preferably removably attached to corresponding frame sections 312. In particular, the connectors 334 are preferably frictionally attached to the respective frame section 312, with the tabs 356 of connectors 334 grabbing and frictionally holding the respective frame section 312.
When attached to the corresponding frame sections 312, the side shell segments 324 preferably span the corresponding frame section 312 and cover the framed area of the corresponding frame section 312. However, it is within the ambit of the present invention where one or more of the side shell segments 324 do not cover the corresponding frame section 312.
For instance, in one alternative embodiment, one or more of the side shell segments 324 could be mounted within the corresponding frame section 312 while also spanning the corresponding frame section. In other words, the side shell segment 324 could be mounted within the framed area of the corresponding frame section 312.
The illustrated side shell segments 324 are preferably installed on each side of the blind 300 in series by starting with the lowermost side shell segment 324 and then attaching subsequent side shell segments 324 in overlapping engagement with the adjacent side shell segment 324. Thus, for each pair of overlapped side shell segments 324 on corresponding sides of the blind 300, the upper one of each overlapped pair of side shell segments 324 preferably overlaps the lower one of the overlapped pair of side shell segments 324 to cooperatively form a side seam 384 (see FIGS. 35 and 36). In this manner, the side shell segments 324 cooperatively restrict water and/or debris from entering the blind 300 along each side seam 384.
The side shell segment 324c is installed after the side shell segments 324a,b are attached to the articulated frame 306. The side shell segment 324c is attached so that the side margins 368 overlap corresponding adjacent side shell segments 324a. Thus, as mentioned above, the side shell segment 324c preferably serves as a cap for the blind 300. However, it will be appreciated that the blind 300 could have an alternative capping structure.
When installed, the side shell segments 324 preferably cooperatively span the framed areas of the frame sections 312 of articulated frame 306. Furthermore, the illustrated side shell segments 324 preferably cooperatively cover the articulated frame 306. However, it is within the ambit of the present invention where at least part of the articulated frame 306 is not covered by the side shell segments 324.
The illustrated side shell segments 324 and end shell segments 326 are preferably not attached directly to one another. Rather, as described above, the side shell segments 324 and end shell segments 326 are attached relative to one another by being removably mounted to corresponding portions of the underlying frame assembly 302. However, for some aspects of the present invention, at least some of the shell segments 324,326 could be attached directly to one another.
In use, the illustrated blind 300 is erected by first erecting the frame assembly 302. In erecting the frame assembly 302, the articulated frame 306 is attached to one of the end frames 308,310 as the one end frame 308,310 is lying along the ground. The other one of the end frames 308,310 is then attached to the articulated frame 306.
The end shell segments 326a,b are then removably mounted on corresponding end frames 308,310. Alternatively, the end shell segments 326a,b can be removably mounted to the end frames 308,310 prior to attaching the articulated frame 306 to the end frames 308,310.
The side shell segments 324a,b,c are then removably mounted on the articulated frame 306, with the side shell segments 324 overlapping the corresponding end shell segments 326. The side shell segments 324 are preferably mounted on each side of the blind 300 in series by starting with the lowermost side shell segment 324 and then mounting subsequent side shell segments 324 in overlapping engagement with the adjacent side shell segment 324. The side shell segment 324c is mounted after the side shell segments 324a,b, with the side shell segment 324c serving as a cap.
The preferred forms of the invention described above are to be used as illustration only, and should not be utilized in a limiting sense in interpreting the scope of the present invention. Obvious modifications to the exemplary embodiments, as hereinabove set forth, could be readily made by those skilled in the art without departing from the spirit of the present invention.
The inventor hereby states his intent to rely on the Doctrine of Equivalents to determine and assess the reasonably fair scope of the present invention as pertains to any apparatus not materially departing from but outside the literal scope of the invention as set forth in the following claims.
