CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation-in-part of U.S. application Ser. No. 17/866,494, filed Jul. 16, 2022, entitled “Portable Multi-hinged Shelter,” which claims the benefit of U.S. Provisional Application No. 63/280,027, filed Nov. 16, 2021, entitled “Multi-hinged Fishing Shelter,” the disclosures of which, including all attached documents, are incorporated herein by reference in their entirety for all purposes. 
    
    
     FIELD OF THE INVENTION 
     The present invention is largely directed to a portable multi-hinged shelter for attachment to and operation with vehicles generally equipped with an open cargo bay or bed, such as a truck, a utility terrain vehicle (UTV), an all-terrain vehicle (ATV), or equivalent. More particularly, the portable multi-hinged shelter offers manual operation for expansion to form an enclosure for occupancy by multiple individuals and storage of cargo and the like and contraction to facilitate convenient self-storage on the vehicle for effectual transport to varying locations or destinations. 
     BACKGROUND OF THE INVENTION 
     Portable shelters or enclosures are often utilized in recreational activities such as ice fishing and camping to protect the enthusiast from the cold and sometimes harsh climatic conditions. Ice fishing, for example, is a popular and favorite outdoor sport or hobby held typically in northern regions of many countries with cold climatic conditions, often necessitating the need for some form of protective enclosure or shelter. Ice fishing in general involves catching fish from atop of an ice sheet formed on a body of water. Access to the aquatic environment that underlies the ice sheet is mainly achieved by drilling or cutting a hole through the ice sheet of sizable dimension to allow ample room for adequately accommodating passage of fish line, a fish catch of varying size and weight, and ancillary fishing equipment like that of a sonar fish finder without undue hinderance and difficulty. Some ice fishing enthusiasts or anglers desirably participate in the sport within the open environment so as take in the fresh air, while others may preferably reside within the comforts of an enclosure to protect them from the elements and harsh cold conditions. 
     Enclosures directed for this purpose may vary in type and size, with some being of the semi-permanent type fabricated from metal or wood to resemble a structured shed or shack and optionally fitted with wheels or skids to fulfill relocation relatively about the ice sheet as may be desired from time to time, whereas other types of enclosures may be extensively portable in nature. Portable shelters that often fulfill the enthusiastic angler&#39;s requirements are typically inexpensive, can accommodate one or more persons, albeit generally limited in number, lightweight for transport to and from the body of water, and incorporate features for quick assembly and disassembly so that one may desirably relocate the shelter coincident to the movement of feeding fish for attainment of the ultimate catch. 
     The construct of and features associated with portable fishing shelters are recognized in the art to vary by some degree, but are generally represented by three basic design types: a pop-up tent, a rigid sled incorporating a flip-over tent, and a flip-over tent connectively adapted to a utility terrain vehicle (UTV) or equivalent. 
     As considered the most basic form of a portable fishing shelter, the pop-up tent fishing shelter is usually featured with similar components as one would find for a tent used in camping, absent an integrated floor structure. This type of the portable shelter typically includes a light-weighted assembly of flexible poles hingedly mounted to and extending from hubs to expand outwardly and forcibly act against an all-encompassing, water-proof fabric skin to rigidly form a structured enclosure suited for occupancy and containment of a minimal amount of fishing gear and the like. Although pop-tent shelters are rather inexpensive and light-weighted for carry and assembly by an individual fishing angler, they can be cumbersome in fulfilling the capability of transporting the desirable amount of fishing gear with that of the pop-up tent, in addition to the difficulty associated with setup, particularly in relation to embedding the requisite anchors within the ice sheet and connecting lines to structural aspects of the pop-up tent to consummate the assembly. 
     In an extended version or variation of the pop-up tent fishing shelter described above, the rigid sled with the flip-over tent type of fishing shelter incorporates within the structure of the sled a pair of sideward anchoring plates that offers mounting of one or more swinging canopy supports that selectively connect in part to an outer, waterproof skin and pivotally rotate relative to the anchoring plate to spatially expand and relocate the outer skin from within the confines of the sled to structurally form an enclosure for occupancy and containment of a limited amount of fishing gear. Like the pop-up tent fishing shelter, the canopy supports inherently possess capabilities to extend outwardly and forcibly act against the outer skin and lock in place to consummate the assembly. Although this type of fishing shelter conveniently offers onboard storage of the outer skin and associated canopy supports to admirably advance aspects portability for transport to the body of water and relocation relatively about the ice sheet at moment&#39;s notice, there is a tendency for premature wear and tear of operative components and hardware as well as calamitous opportunities for damaging fishing gear and sensitive equipment due to traversing over rough sheets of ice and mounds of snow, particularly if the sled is being transported behind a moving vehicle like that of a snowmobile or UTV and the like. Additionally, this type of fishing shelter, like that of the pop-tent type, is spatially limited for occupancy and storage of fishing gear, can be difficult for one to manage setup during adverse climatic and windy conditions, and with due consideration of its weight and overall bulkiness and sizable dimension, can be problematic for the individual user to load and unload the fishing shelter respectively into and from the vehicle, which, on most occasions, necessitates use of a truck or an equivalent type of vehicle offering sizable holding capacity. 
     Like the two previously described portable fishing shelters, the flip-over tent for UTV&#39;s utilizes a plurality of flexible canopy supports and an attachable stretchable fabric skin capable of being attached to and expanded outwardly from the UTV to form an enclosure, generally offering a minimal footprint with limited overall spatial capacity for comfortably accommodating multiple anglers and fishing gear. As with most designs of this type, the flexible canopy supports and attachable fabric skin typically collapse or fold together to attain a level of compactness for convenient storage within the spatial confines of a cargo bay or bed of the UTV, which in turn adversely limits the vehicle&#39;s onboard storage capacity for carrying fishing gear and ancillary necessities. Although this type of portable fishing shelter may possess practicality and convenience for most anglers, there still remains unresolved issues of utilizing flexible canopy supports that are inherently difficult to manage during adverse, climatic conditions and are prone to breakage. Furthermore, inadvertent jarring of the vehicle during travel and snow and ice unwantedly accumulating within the bed of the UTV may unduly compromise vital operating components of the flip-over tent as well as fishing gear that may accompany transport therewith. 
     Accordingly, there remains a need for a portable multi-hinged shelter that is adaptable for use with most vehicle types having an open cargo bay or bed and incorporates structural components for readily forming a structural enclosure that sufficiently and comfortably accommodates one or more individuals and accompanying gear and attains a level of compactness for onboard storage on the vehicle without unduly compromising the vehicle&#39;s overall spatial capacity to stow and transport ancillary necessities and items typically relating to an outdoor excursion.

     DETAILED DESCRIPTION OF THE INVENTION 
     While this invention is susceptible of being embodied in many different forms, the preferred embodiment of the invention is illustrated in the accompanying drawings and described in detail hereinafter with the understanding that the present disclosure purposefully exemplifies the principles of the present invention and is not intended to unduly limit the invention to the embodiments illustrated and presented herein. The present invention has particular utility as a portable shelter for outdoor excursions and like activities with structural features that readily advance assembly for immediate occupancy by one or more individuals and storage of accompanying gear and ancillary items, while equally possessing capabilities to attain a level of compactness for onboard, self-storage in connection with a variety of vehicle types. 
     Referring now to  FIGS.  1 - 4   , there is shown generally at  10  a portable multi-hinged shelter in expanded form and mounted and attached to a vehicle  12  of the particular type equipped with an open cargo bay  12   a  or bed, with a portion of the portable shelter extending outwardly from a rearward end  12   b  of the vehicle to advance an increase in spatial capacity for comfortably accommodating one or more individuals and storage of accompanying equipment and related gear. As further shown therein, the portable multi-hinged shelter includes a protective shell assembly  14  semi-permanently attached to and exteriorly covering a box frame  16  and a moveable frame assembly  18 , in addition to incorporating an integral assembly of flaps  20  suited to protectively wrap and encase the moveable frame assembly while presented in collapsible form, primarily in preparation for transport. 
     The box frame  16  in  FIGS.  5 - 8    preferentially resides above the open cargo bay  12   a  and is configured to attach to sidewalls  12   c  substantially forming the cargo bay of the vehicle and includes four corner posts  22  generally extending vertically in alignment with the sidewalls and perpendicular to a bottom surface  12   d  of the open cargo bay, with each of the corner posts having a first end  22   a  and a second end  22   b  respectively connecting to upper horizontal members  24  and lower horizontal members  26  by way of a three-way connector  28 . The three-way connector in particular is shown in  FIGS.  9 - 14    to include an aperture  30  extending through each of the three walls  28   a  of the three-way connector for accepting therethrough a cap screw  32  or equivalent, with a threaded end  32   a  thereof being threadably inserted within a cylindrical bore  22   c,    24   a,    26   a  extending lengthwise about the corner post as well as of each of the upper and lower horizontal members. Accessible openings  34  supplement the three-way connector to allow access to and passage of the cap screw for advancing and consummating assembly. To promote proper alignment and positioning of the corner posts  22  with respect to the horizontal members  24 ,  26 , the three-way connector as in  FIGS.  11  and  12    incorporates within its structure an alignment member  36  extending outwardly from a backside  28   b  of each wall configured with the aperture for fitment within an open track  22   d,    24   b,    26   b  integrated within and extending lengthwise along each of the corner posts and horizontal members, generally formed within each as an extrusion. A corner cap  38  of the type depicted in  FIGS.  13  and  14    encases the three-way connector, whereby connectivity is maintained by a pair of outward pins  40  that engage and snap in place within corners of an open side  28   c  of the three-way connector  28 , while a pair of inversed grooved slides  42  engagingly mate with an equally configured pair of inversed grooved slides  44  integrated within the structure of the three-way connector&#39;s walls bearing the accessible openings. 
     As further depicted in  FIGS.  7  and  8   , the box frame  16  incorporates one or more intermediate members  46  to supplement its overall strength and rigidity and generally connect midway to each of the upper horizontal members  24  and lower horizontal members  26  as well as extending in between a pair of parallel upper horizontal members  48 . Connection of the individual intermediate members in this regard may be advanced by a common connective assembly  50  primarily comprising a cap screw  50   a  or equivalent passing into and fitting within a cross bore  24   c,    26   c  extending perpendicularly through the upper and lower horizontal members, whereupon the cap screw&#39;s threaded end threadably engages a cylindrical bore  46   a  of the intermediate member  46 . 
     In some embodiments of the present invention, as represented in  FIGS.  5 ,  6 ,  15 , and  16    the box frame  16  may be fitted with an optional shelf system that fulfills expanded storage capabilities for items and the like interiorly within the confines of the portable shelter  10 . In this regard, a pair of shelf supports  52  individually extend horizontally in between and connect to one of the four corner posts  22  and a vertically orientated intermediate member  54 , generally in the manner shown in  FIGS.  7  and  8   . Connection is maintained by the common connective assembly  50 , whereby by individual cap screws  50   a  fit within a cross bore  22   e,    54   a  respectively extending through the corner post and vertically orientated intermediate member and threadably engage and terminate within a cylindrical bore  52   a  of the shelf support  52 . In completing assembly of the shelf system, a shelf platform  56  is illustrated in  FIGS.  5  and  6    to extend to each of the mounted shelf supports  52  and attaches thereto by way of a cap screw  58  or equivalent fitting within a cylindrical sleeve  60  fixedly attached to each corner of the shelf platform. A track nut  62  of the type shown in  FIG.  16    includes an overall geometric shape that enables it to slidably pass into and within an open track  52   b  of the mounted shelf support  52  yet inhibits upward movement as the cap screw  58  is tightened to a specified torque setting. Although the construct of the shelf platform  56  may exist in numerous forms, practically adapting use of the types conventionally known in the art, it is preferably fabricated from a plurality of inner supports  56   a  spaced apart from one another and bounded by and connected at their ends to a supportive frame  56   b  so as to maintain passing of light from above-positioned light fixtures that may be used within the interior of the portable shelter  10 . In some installations, where it is desired to increase the supportive strength of the shelf platform for heavily-weighted items, a stacked arrangement of shelf platforms may be aptly connected together by way of the cylindrical sleeves  60 , typically in the manner depicted in  FIG.  16   . 
     As illustrated in  FIGS.  6 ,  17  and  18   , the box frame  16  is preferentially attached to the vehicle&#39;s cargo bay  12   a  by way of an assembly of eye bolts  64  and multiple turnbuckles  66  of the type generally recognized in the art for such applications, with each of the turnbuckles having a pair of ends  66   a  individually configured with a connective hook  66   b  or equivalent and a tensioning mechanism  66   c  operating conjunctively with threaded stem portions  66   d,  whereby turning of the tensioning mechanism clockwise or counterclockwise respectively shortens or lengthens the effective length of the turnbuckle. In fulfilling attachment of the turnbuckles  66  to the box frame, one end bearing the connective hook  66   b  engages a lowermost eye bolt  68  fixedly mounted to the open cargo bay&#39;s bottom surface, whereas the other, companion connective hook is configured to engage an uppermost eye bolt  70  extending outwardly from and connecting to one of the lower horizontal members  26 . Adjustability of the eye bolt along the lower horizontal members is fulfilled by the capabilities of a track nut  72  slidably fitting within the open track  26   b,  whereas a threaded portion  70   a  of the eye bolt passes into and threadably engages the track nut to consummate a secured arrangement, as generally depicted in  FIGS.  17  and  18   . 
     In further association with the box frame  16 , a plurality of alignment plates  74  may be employed to ensure proper orientation and alignment of the box frame relative to the open cargo bay  12   a  while positioned atop the sidewalls  12   c  thereof. As can be seen in  FIGS.  19  and  20   , each alignment plate includes a top planar element  76  integrally connecting to and being perpendicularly orientated to a sideward planar element  78 , where the top planar element is configured to sit atop of and engage the lower horizontal member with the sideward planar element being situated to simultaneously abut against the horizontal member and an inner wall surface  12   e  of the cargo bay&#39;s sidewall. Moveability and securement of the alignment plates relative to and along the lower horizontal member  26  is furthered by an assembled arrangement of a cap screw  80  passing into an aperture  76   a  extending through the top planar element  76  where it is allowed to threadably engage a track nut  82  capable of sliding along the open track  26   b  of the lower horizontal member  26  and being tightened to fulfill securement of the alignment plate. 
     Now in reference to  FIGS.  21 - 24   , the portable shelter  10  is further associated with a supportive wind wall  84  possessing structural features for connecting the box frame  16  to the moveable frame assembly  18  as well as supporting connectivity of a lower wind wall  86  that possesses capabilities of being moved inwardly toward the supportive wind wall and stowed for transportational purposes. 
     The supportive wind wall in particular is shown in  FIGS.  21  and  24    as having a pair of upright supports  88  each configured with a top end  88   a  and a bottom end  88   b  respectively connecting to an upper outward member  90  and a lower outward member  92  at each of their first ends  90   a,    92   a  by way of a two-way corner connector  94  and a three-way corner connector  96 .  FIGS.  25  and  26    generally illustrates the overall configuration of each corner connector, where an insertable end  94   a,    96   a  integrally formed with and extending outwardly from an exposed corner member  94   b,    96   b  associated therewith geometrically conforms to and fits interiority within the structural square tubing preferentially used in fabricating the moveable frame assembly  18 . It is generally understood within the context of this disclosure that the insertable end may be permanently or temporarily attached to the corresponding structural tubing by a variety of attachment means conventionally known in the art, including, but not limited to, press-fitted, screws, bolts, rivets, glue, and so forth. 
     As generally depicted in  FIGS.  21 - 23 ,  27 , and  28   , as an alternative, second embodiment of the moveable frame assembly  18 , each of the upright supports of the supportive wind wall  84  may be outfitted with dual-mountable pivot plates  98  in lieu of the upper outward member to advance connectivity to a sideward arm  100 . Connection of the dual-mountable pivot plates to the upright supports  88  is preferably maintained by attachment means relatively at its attachable end  98   a,  such as multiple bolt and nut assemblies  98   b  of the type typically shown in  FIG.  21   , rivets, screws, welds, and other methodologies recognized in the art for this purpose. Regardless of the overall construct of the supportive wind wall, each of the upright supports is further featured with at least one pair of supportive plates  102  that engagingly connect to an equal number of complementary supportive plates  104  extending outwardly from and connecting to the corner post  22  of the box frame  16  situated most rearward of the vehicle  12 .  FIG.  28    shows a typical arrangement of the supportive plates with that of the complementary supportive plates, whereby individual sets of bolt and nut assemblies  106  advance a temporary fixed connection thereof. 
     In fulfilling connection of the two upright supports  88  as well as offering overall structural support to the lower wind wall  86 , each of the bottom ends  88   b  in  FIGS.  21  and  22    connects to ends  108   a  of a lower support member  108  by way of one of the available insertable ends  96   a  of the three-way connector, particularly in a manner that allows the lower support member to generally reside on the same plane as the upright supports with the lower outward member  92  extending outwardly perpendicular thereto to advance connectivity to the lower wind wall. 
     Comparatively,  FIGS.  29  and  30    respectively show each of the upper outward members  90  or pair of dual-mountable pivot plates  98  as associated with the alternative embodiment of the moveable frame assembly  18  being connected to the sideward arm  100  in a manner that yields pivotal action relatively at an inward end  100   a  of the sideward arm. In applications employing usage of the upper outward members, for example, a pair of opposing inline plates  110  facilitates connectivity as well as providing for the desirable pivoting movement, where in particular a fixed end  110   a  of the inline plate is fixedly attached to the inward end of the sideward arm by fastening means, such as at least one pair of bolt and nut assemblies  112  of the type shown in  FIG.  29   , welds, or equivalent, whereas a free end  110   b  of the inline plate connects to a second end  90   b  of the upper outward member by pivot fastening means, such a singular bolt and nut assembly with inner washers possessing lubricity properties, a bolt, a pin, or equivalent types of fasteners capable of yielding pivoting movement. In like manner, the dual-mountable pivot plates  98  each includes an aperture  98   c  extending through a pivoting end  98   d  thereof as in  FIG.  21    to align with a cross bore  100   b  extending through the inward end  100   a  of the sideward arm as in  FIG.  31   , of which is appropriately fitted with pivot fastening means. Referring now to  FIGS.  24 ,  32  and  32 A , the lower wind wall is shown as including a supportive framed structure  114  pivotally connecting to a pair of rotatable arms  116  with each having a first end  116   a  pivotally connecting to a second end  92   b  of the lower outward member  92  to substantially form a lower wind wall with dual-hinged capabilities, whereby the lower wind wall is capable of pivot movement relatively at PB-A along path A in the direction of A′ toward the supportive wind wall to effect a compact relationship, and conversely, in the direction of A″ to effect expansion thereof with that of the moveable frame assembly  18 , as generally represented in  FIG.  30   . The supportive framed structure is generally depicted in  FIG.  32    as comprising a pair of supportive end members  118  with each having a first end  118   a  connecting to ends  120   a  of a cross beam  120  by way of the two-way corner connector  94 , particularly being arranged to allow the supportive end members to reside on the same plane as the cross beam. A handle assembly  122  of the type generally shown in  FIG.  32 A  preferably fulfills connectivity of a second end  118   b  of the supportive end member with that of a second end  116   b  of the rotatable arm and the second end  92   b  of the lower outward member  92  with that of the first end  116   a  of the rotatable arm. The handle assembly, as exemplarily described for use in connecting the supportive framed structure to the rotatable arm as in  FIG.  32 A , aptly includes a bolt  124  slidably fitting within an aligned arrangement of cross bores  118   c,    116   c  extending through the second ends of the supportive end member and rotatable arm and being fixed thereat by a lock nut  126  situated thereinbetween, whereas a threaded exposed end  124   a  of the bolt is threadably fitted with a sleeve  128  that connects to and conjunctively operates with a handle  130  for manually tightening or loosening the connection on an as-needed basis. 
     Now in reference to  FIGS.  27 ,  33  and  33 A , the moveable frame assembly  18  is further associated with a primary canopy  132  extending from and connecting to outward ends  100   c  of the sideward arms  100  and a secondary canopy  134  connecting intermediate along the sideward arms, whereby each of the canopies possesses the capabilities of collapsing inwardly toward the sideward arms as well as traveling outwardly therefrom respectively along paths C and D in  FIG.  30    to attain contraction and full expansion of the moveable frame assembly  18 . 
     As generally depicted in  FIGS.  29 ,  33  and  34   , the primary canopy  132  includes a pair of sideward members  136  each having a first end  136   a  connecting to ends  138   a  of a cross member  138  by way of the two-way corner connector  94 . The primary canopy is further shown as including a shortened arm  140  generally extending perpendicular to the sideward member  136  and connecting intermediate along thereof to a second end  136   b  of the sideward member by way of a pair of opposing T-plates  142  each having an outward portion  142   a  and a lengthened portion  142   b,  of which may be fastened by bolt and nut assemblies  144  as in  FIG.  29   , welds, or equivalent fastening means known in the art. In other featural aspects of the primary canopy  132 , each of the shortened arms includes first and second ends  140   a,    140   b  respectively connecting to the outward end  100   c  of the sideward arm  100  and a first end  146   a  of a sideward support  146  of a ground brace  148  by way of a pair of opposing inline plates  150  of the type shown in  FIGS.  35  and  36   , particularly equivalent to the type used for pivotally joining the inward end of the sideward arm to the upper outward member of the supportive wind wall. In the instance of their usage, a fixed end  150   a  of the individual inline plates is shown in  FIG.  29    as being fixedly attached to the outward end  100   c  of the sideward arm as well as the second end of the sideward support by fastening means, such as bolt and nut assemblies  152  as in  FIG.  29   , welds, or equivalent fastening methodologies known in the art. Comparatively, a free end  150   b  of the individual inline plate providing for capabilities for pivotal movement is shown as being attached to the first and second ends of the shortened arms by pivot fastening means, such as a bolt and nut assembly  154  as in  FIG.  29   , pass-through pin or bolt with locking capabilities, such as a lockable cross pin, cotter pin, couplers, eye pin, and so forth, or equivalent structural forms known in the art for fulfilling pivotal movement. 
     As an alternative embodiment, in lieu of the shortened arm, the primary canopy may connect to the sideward arms and ground brace by way of a pair of dual triangulated pivot plates  156  each configured with a pair of outward ends  156   a  and arranged in an opposing manner, whereby a fixed connection is maintained with the sideward members of the primary canopy by fastening means, such as bolt and nut assemblies  158  as in  FIG.  33   , welds, or equivalent methodologies known in the art for this strict purpose. Pivoting connectivity of the outward ends of the dual triangulated pivot plates with the outward end  100   c  of the sideward arm  100  and sideward support  146  of the ground brace is fulfilled by pivot fastening means to the likes noted above for the opposing inline plates. 
     As generally represented in  FIGS.  37  and  38   , the secondary canopy  134  is shown therein as possessing similar structural characteristics as the primary canopy, but differs slightly with respect to its mounting to the sideward arm  100 , particularly as such to allow full collapse inwardly toward the supportive wind wall  84 . Accordingly, the secondary canopy includes a pair of sideward members  160  each having a first end  160   a  connecting to ends  162   a  of a cross support  162  by way of the two-way corner connector  94 . Connection of the secondary canopy to the sideward arm may be fulfilled by a pivot bracket assembly  164  as in  FIG.  27    or by a pair of opposing T-plates  166  as in  FIG.  29   . 
     The pivot bracket assembly as generally represented in  FIGS.  39  and  40    provides for pivotal connection of the sideward members  160  to the sideward arms  100 , whereby an end-mountable bracket  168  and a plate-mountable bracket  170  respectively attach to the second end  160   b  of each sideward member and intermediate along each of the sideward arms  100  of the moveable frame assembly  18 . As generally depicted in  FIGS.  39  and  40    the end-mountable bracket includes an insertable end  168   a  integrally connecting to and extending inline and outwardly from an off-setting protuberance  168   b  configured with a cross bore  168   c.  The end-mountable bracket is further shown in  FIG.  39    as having a formed ridge  168   d  situated in between the insertable end and off-setting protuberance to serve as a stop mechanism as the insertable end slidably fits interiorly within the tubing of the sideward member. Permanent or temporary fastening of the insertable end to the sideward member may be maintained by screws, bolts, glue, and other methodologies recognized in the art for this purpose. 
     Comparatively, the plate-mountable bracket  170  is shown in  FIGS.  39  and  40    as comprising a complementary offsetting protuberance  170   a  integrally connecting to and extending outwardly from a base plate  170   b,  whereby the complementary offsetting protuberance engagingly mates with the adjacently-placed offsetting protuberance  168   b  of the end-mountable bracket and connects therewith by way of a bolt and nut assembly  172  appropriately suited for fitment within the arrangement of bores  168   c,    170   c  extending through the offsetting protuberances. Connection of the plate-mountable bracket is generally fulfilled by at least two bolts  174  or equivalent passing into and through an aligned arrangement of apertures  176  extending through the base plate of the plate-mountable bracket and sideward arm and threadably fitted with nuts  174   a.    
     In instances of using the opposing T-plates  166  for joining the secondary canopy to the sideward arm of the type represented in  FIGS.  41  and  42   , a lengthened portion  166   a  thereof is fixedly attached to the sideward arm  100  by fastening means, such as bolt and nut assemblies  166   b  as in  FIG.  29   , welds, rivets, or equivalent, whereas an outward portion  166   c  is attached to the second end  160   b  of the sideward member  160  by pivot fastening means, such as a singular bolt and nut assembly  166   d  as in  FIG.  42   , a pin with locking capabilities, or equivalent type of fastener capable of fulfilling pivotal action thereabout. 
     Consequently, through the structural connective arrangement of the end-mount and plate-mountable brackets, the secondary canopy  134  can pivotally travel relatively about PB-D inwardly toward the sideward arm  100  in direction of D′ along path D in  FIG.  30    until the first end of the sideward member  136  generally comes in proximate contact with the inward end  100   a  of the sideward arm as in  FIG.  27   . Conversely, the secondary canopy  134  can travel outwardly away and apart from the sideward arm  100  in direction of D″ along path D to the extent of establishing a near-perpendicular orientation thereof with respect to the sideward arm, as generally shown in  FIG.  30   . 
     In reference to  FIGS.  43  and  44   , the portable shelter  10  incorporates within its structure the ground brace  148  to provide for overall structural support of the moveable frame assembly  18  while presented in expanded form for accommodating occupancy by individuals Similar to the construct of the primary and secondary canopies, each of the sideward supports  146  of the ground brace  148  is shown in  FIG.  43    as comprising a second end  146   b  connecting to one of two ends  178   a  of a cross member  178  by way of the two-way corner connectors  94  with the insertable ends  94   a  associated therewith being permanently or temporarily attached by fasteners of the type recognized in the art for such purpose, including, press-fitted, screws, bolts, glue, or equivalent. As generally illustrated in  FIGS.  29  and  30    and discussed above, adaptation of the opposing T-plates or dual triangulated pivot plates  156  for joining the sideward supports  146  to the primary canopy  132  aptly allows the ground brace  148  to pivot and move inwardly with respect to the primary canopy  132  to fulfill states of partial compactness and expansion of the moveable frame assembly  18  as may be desired from time to time. 
     As further associated with the portable shelter  10 , the primary and secondary canopies as well as the ground brace may include multiple pairs of corner braces  180  of the type shown in  FIGS.  45  and  46    to offer structural strength and advance rigidity thereto, particularly among areas most prone to possible permanent disfiguration due to applied twisting and torsional forces that the portable shelter may sustain during operative events. Accordingly, it is desired to place and mount pairs of corner braces in an opposing manner relatively on each side of individual two-way and three-way corner connectors that effect to join the sideward members  136  with that of the cross member  138 , as generally associated with the primary canopy, and sideward members  160  with that of the cross support  162 , as generally associated with the secondary canopy  134 , as well as other structural components requiring supplemental support and rigidity. Like the opposing line plates, the corner braces are fastened to the appropriate, designated structure by fastening means, such bolt and nut assemblies  180   a  as in  FIGS.  45  and  46   , rivets, or equivalent. Now in reference to  FIGS.  47 - 49   , the portable shelter  10  incorporates within its overall structure a supportive extending assembly to assistively extend the moveable frame assembly  18  from the supportive wind wall  84  while in a contracted relation and offer continued support thereof while in an expanded relation. 
     As generally depicted in  FIG.  47   , the supportive extending assembly  181  includes a pair of angular moveable supports  182  each extendably spans the connective arrangement of the upright support  88  and sideward arm  100  to afford pivotal rotation relatively about a pivoting end  98   d  of the dual-mountable pivot plates  98  or free end  110   b  of the connected, opposing pairs of inline plates  110  generally designated at PB-B, whereby the sideward arms  100  primarily travel along path B in direction B′ to generally reside in proximity to the upright supports of the supportive wind wall  84  to effect a compact relationship thereof and, conversely, along path B in direction B″ to extend outwardly from the upright support of the supportive wind wall to effect a fully expanded relationship, as generally represented in  FIG.  30   . Each angular moveable support  182  is shown in  FIG.  47    as comprising a rigid member  184  having a first end  184   a  operably connecting to a slidable yoke assembly  186  and a second end  184   b  operably connecting to a pivot bracket assembly  188  of which respectively attaches to the sideward arm  100  and upright support  88  of the supportive wind wall. The slidable yoke assembly, as particularly shown in  FIGS.  47  and  48   , includes an arm-encompassing sleeve  190  capable of being slidably fitted to the sideward arm  100  and a pair of flanges  186   a  integral to and extending from one wall  186   b  of the arm-encompassing sleeve to form an inner slot  186   c  for receiving therein a center-positioned protuberance  192   a  of an end-mountable pivot bracket  192 . In  FIG.  47   , the end-mountable pivot bracket is further associated with an insertable end  192   b  integrally connecting to and extending outwardly from an intermediate ridge  192   c  that adequately serves as stop mechanism to the likes described above for the end-mountable bracket  168  of the pivot bracket assembly  164 , whereby the insertable end may be permanently or temporarily attached to the first end of the rigid member  184  of the angular moveable support by a variety of fasteners generally known in the art for such purpose. Connectivity between the slidable yoke assembly  186  and the center-positioned protuberance  192   a  is furthered by a bolt and nut assembly  194 , wherein the bolt  194   a  fits within an aligned arrangement of apertures  192   d,    186   d  extending through a face  192   e  of the center-positioned protuberance and pair of flanges  186   a  with a nut and washer  194   b  being mounted to the bolt to consummate the assembly. Comparatively, the pivot bracket assembly  188  appropriate for connecting the upright support to the angular moveable support  182  as in  FIG.  49    is structurally equivalent to the type used in connecting the secondary canopy  134  to the sideward arms  100 , whereby a plate-mountable bracket  196  is mountable to the upright support  88  with fastening means, such as bolt and nut assemblies  196   a,  screws or equivalent, while the end-mountable bracket  198  with an insertable end  198   a  is fitted interiorly within the second end  184   b  of the rigid member  184 . In completing the assembly, off-setting protuberances  196   a,    198   b  integrally made part of the plate- and end-mountable brackets are placed adjacent to one another and connected together by pivot fastening means, such a bolt and nut assembly  200  or equivalent to fulfill capabilities of pivotal movement thereabout, as typically shown in  FIGS.  39 ,  40  and  49   . 
     As generally depicted in  FIGS.  50 ,  50 A and  51   , the supportive extending assembly may alternatively comprise a pair of telescopic supports  202  that connectively span from the upright supports  88  to the sideward arms  100 , whereby first and second ends  202   a,    202   b  of the telescopic support respectively connect to outward portions  204   a,    206   a  of upper and lower sets of opposing T-brackets  204 ,  206 . In particular, each telescopic support is shown in  FIGS.  50  and  51    as comprising an inner slidable support  208  slidably fitting interiorly within an elongate sleeve  210  that geometrically conforms therewith. The elongate sleeve includes a first open end  210   a  and a second open end  210   b  respectively accommodating an end cap  212  and a bushing  214  capable being placed interiorly in part within the elongate sleeve while permitting a portion of the inner slidable support  208  to slidably pass through an opening  214   a  associated with the bushing. Comparatively, the inner slidable support is shown to include an open end  208   a  for accommodating therein an insertable end  216   a  of a fitted stop mechanism  216 , whereby an enlarged portion  216   b  integrally extending outwardly from and in line with the insertable end forms a peripheral rim  218  that aptly engages with and abuts against an end wall portion  208   b  of the inner slidable support while being fixedly attached thereto. As further evident in  FIG.  50 A , the enlarged portion includes a spring-loaded pin  216   c  of conventional form and is geometrically configured to tightly fit, but slide interiorly within the elongate sleeve  210 , whereby formed surface ridges  216   d  existing exteriorly on the enlarged portion are capable of interactively engaging with and sliding relatively about the elongate sleeve&#39;s inner walls without profound resistance while the inner slidable support slidably moves in position to allow the spring-loaded pin to lockingly engage with one of a plurality of apertures  210   c  extending through a wall section  210   d  of the elongate sleeve  210 .  FIGS.  24  and  29    generally depict connectivity of each of the telescopic supports to the individual sets of T-brackets, where in particular a lengthened portion  204   b,    206   b  of each of the upper and lower sets of opposing T-brackets  204 ,  206  is respectively attached to the sideward arm  100  and upright support  88  by fastening means, such as bolt and nut assemblies  220  as in  FIGS.  41  and  42   , welds, or equivalent methodologies known in the art. Conversely, attachment of the first and second ends of the telescopic supports to each of the outward portions  204   a,    206   a  of the upper and lower T-brackets is fulfilled by pivot fastening means, such, for example, a bolt and nut assembly  222  with the bolt respectively passing through an aligned arrangement of apertures  202   c,    204   c,    206   c  extending individually through the first and second ends of the telescopic support and outward portions of the upper and lower sets of opposing T-brackets designated therefor with nuts being threadably attached thereto to complete the assembly. 
     As generally shown in  FIGS.  52 - 54   , the protective shell assembly  14  comprises a primary shelter shell  224  designated for use with the moveable frame assembly  18  and a secondary shelter shell  226  designated for use with the box frame that generally exists separable from the primary shelter shell, but semi-permanently attached thereto to facilitate assembly and disassembly for repairs that may be needed from time to time, for example, as well as providing for varied use of the box frame  16 , with and without the secondary shelter shell, apart from the moveable frame assembly  18 , with and without the primary shelter shell, and vice versa. 
     The primary shelter shell  224 , as represented in  FIGS.  52 - 54   , includes a top-rearward panel  228  integrally including a bottom outward flap  230  to engage with the ground&#39;s surface that functionally mitigates updrafts into an interior compailinent  232  of the portable shelter and an extending top flap  234  of the integral assembly of flaps  20  used in part to encase the moveable frame assembly while presented in collapsible form for transportational purposes. Other notable features of the top-rearward panel as in  FIG.  52    include an integrated rearward access door  236  operably configured with a zipper  236   a  or equivalent type of closure mechanism for sealing the doorway and one or more windows  238  with each having a closable flap  240  configured with a hook-and-loop fastener or equivalent attached along a top side thereof. 
     In  FIGS.  1 - 4  and  52 - 54   , the primary shelter shell  224  further includes a pair of side panels  242  each including a common perimeter edge  242   a  sewnly attached to and along a common sideward edge  228   a  of the top-rearward panel, a bottom outward flap  244 , an integrated door  246  to the likes set forth for the top-rearward panel, one or more sealable air vents  248 , an elongate sideward flap  250  possessing protective functionality substantially equivalent to the extending top flap  234  for transportational purposes, and a sideward closure flap  252  for enclosing an elongate area  254  formed in between the supportive wind wall  84  and corner post  22  of the box frame  16 , as generally depicted in  FIG.  28   . 
     In further association with the primary shelter shell  224 , as shown in  FIGS.  53  and  55 - 58   , a pair of bottom panels  256  is fixedly positioned relatively about the lower wind wall  86 , where in particular each bottom panel includes an outer sideward edge  256   a  sewnly attached to a lower perimeter edge  242   b  of the side panel and a common interior edge  256   b  configured with a hook-and-loop fastener  258  or equivalent to engagingly mate with its complementary hook-and-loop fastener or equivalent associated with the adjacent, companion bottom panel. 
     Connection of the primary shelter shell to the moveable frame assembly  18  as in  FIG.  3    is mainly provided by multiple straps  262  extending outwardly from and attaching to an interior surface  224   a  of the primary shelter shell. Each of the straps generally incorporates at its end a fastener  264  in the form of a hook-and-loop fastener, a D-ring  264   a,  snap, button, or other suitable types generally recognized in the art for fulfilling this purpose. Configuration and securement of the straps  262  specifically in relation to the cross member of the primary canopy, cross support of the secondary canopy, and cross member of the ground brace generally involves encircling the straps around each of the foregoing structures and affixing their position with the fastener.  FIG.  3    illustrates exemplarily availability of straps individually configured with a D-ring to effect connection of the top-rearward panel  228  to available loop brackets  266  extending outwardly from and connecting to the sideward support and cross member  178  of the ground brace  148  and bottom panels  256  of the lower wind wall  86 . 
     Comparatively, the secondary shelter shell  226 , as generally depicted in part in  FIGS.  59 - 61   , is shown therein as including a frontal-top-rearward panel  268  selectively positioned over front, top and back sides of the box frame  16 , whereby a rearward side  268   a  of the frontal-top-rearward panel includes an access door  270  configured with a zipper  270   a  or equivalent closure mechanism to possibly cordon off an interior space formed by the box frame and interior area of the moveable frame assembly  18  or offer complete enclosure of the box frame  16 , generally in instances of desirable non-use of or being disassembled apart from the moveable frame assembly  18 . 
     In completing enclosure of the box frame, as depicted in  FIGS.  62 - 64   , the secondary shelter shell  226  includes a pair of box side panels  272  each having an upper perimeter  272   a  and a pair of sideward edges  272   b  sewnly attached to a common sideward edge  268   b  of the frontal-top-rearward panel  268 . Other aspects of each box side panel as in  FIGS.  62  and  64    include an optional window  274  and zippered door  276  to gain convenient access to the interior space of the box frame and an integral sideward flap  278  configured with a hook-and-loop fastener  280  that selectively mates with a hook-and-loop fastener  252   a  integral to the structure of the sideward closure flap  252  of the side panel  242 , of which supplementally serves to protectively enclose the elongate area  254  formed in between the upright support  88  of the supportive wind wall and corner post  22  of the box frame. Connection of the secondary shelter shell  226  to the box frame  16  is fulfilled by a plurality of straps  282  with each extending outwardly from an interior side  268   c,    272   c  of the frontal-top-rearward panel and box side panel  272  and being configured with a fastener of the type generally associated, for example, with the top-rearward panel. In advancing a tight seal between the primary shelter and secondary shelter shells, an assembly of segmented straps  284  as in  FIGS.  2 ,  56  and  58    are provided to slidably fit and reside within formed sleeves  252   b,    228   b,    256   c  respectively integral to the sideward closure flap  252  of the side panel  242 , top-rearward panel  228 , and pair of bottom panels  256 . Fasteners  286  in the form of a buckle  286   a,  hook-and-loop fasteners, snaps, buttons, or equivalent provide means for connecting together ends  284   a  of the segmented straps. 
     Now by way of briefly exemplifying description of the assembly and functionally of the portable shelter  10 , one may appreciably gain further insight into the relatedness and interaction of the operative components discussed thus far that principally fulfill the utilitarian objects of the invention. 
     The box frame  16  is initially assembled by way of connecting together the corner posts  22  with that of the upper and lower horizontal members  24 ,  26  with structural provisions being made for mounting one or more shelves. The resultant box frame is selectively positioned about the sidewalls  12   c  of the open cargo bay and partially fitted with the secondary shelter shell  226  before finalizing attachment to the open cargo bay  12   a  by way of the turnbuckles  68 . 
     Comparatively, the moveable frame assembly  18  is preferably assembled in whole as a structure without the primary shelter shell  224  before being fixedly attached to the box frame, where in particular the supportive wind wall  84  pivotally connects to the lower wind wall  86  and the pair of sideward arms  100  followed by the primary canopy pivotally connecting to the sideward arms, the ground brace  148  pivotally connecting to the primary canopy  132 , and the secondary canopy  134  pivotally connecting to the sideward arms. In fulfilling manual operation for contraction and expansion of the portable shelter  10 , the supportive extending assembly, which preferably exists in form as pairs of angular moveable supports or telescopic supports, are selectively mounted within the structure of the moveable frame assembly. Regardless of using either the angular moveable supports or telescopic supports, which are shown in  FIGS.  29  and  30    as connectively spanning from the upright supports of the supportive wind wall to the sideward arms  100 , each possesses capabilities for pivotally moving the sideward arms outwardly from and inwardly toward the upright supports  88  of the supportive wind wall  84  along path B in  FIG.  30   . 
     Once in assembled form, the moveable frame assembly  18  is selectively located in vicinity of the box frame and positioned in a manner to allow the supportive plates connected to the rearward corner post  22  of the box frame  16  and supportive wind wall  84  to engagingly mate with one another, where in particular the supportive plates  102  mounted to the supportive wind wall rest upon the complementary supportive plates  104  affixed to and extending outwardly from the rearward corner posts. A bolt and nut assembly  106  accompanying and fitting to each of the mating, overlapping supportive plates consummates a secured connection of the moveable frame assembly to the box frame. After attachment in this regard, the primary shelter shell  224  is fitted relatively about and over the moveable frame assembly  18  and affixed thereto by means of the straps  262 , with sideward closure flaps  252  of the side panel  242  of the primary shelter shell engagingly mating with the integral sideward flap  278  of the box side panels  272  of the secondary shelter shell  262  by way of the hook-and-loop fasteners. 
     In operational configurations of the portable shelter  10 , the moveable frame assembly, as associatively attached to the box frame  16 , is presented in expanded form with and without attachment of the primary shelter shell  224 , as in  FIGS.  30  and  65   , and, conversely, in contracted form, as in  FIGS.  27  and  28    to permit encasement thereof by way of the integral assembly of flaps  20 , particularly the extending top flap  234  and elongate sideward flap  250 , with provisions for securement thereof by multiple elongate straps  288  configured with fasteners  290  in the form of buckles  290   a,  hook-and-loop fasteners, snaps, buttons, ties, or equivalent, primarily in preparation of transport. 
     In the exemplary instance of using the angular movable supports  182  to yield overall contraction of the moveable frame assembly  18 , the arm-encompassing sleeves  190  of the slidable yoke assembly  186  are slidably moved along the sideward arms  100  in the direction of A′ in  FIG.  30    toward the inward end  100   a  of the sideward arm, where in particular the sideward arms will pivot relatively at PB-B while moving inwardly along path B in the direction of B′ toward the supportive wind wall. At the same time, the primary and secondary canopies will respectively pivot relatively at PB-C and PB-D while moving inwardly along paths C and D in the directions of C′ and D′ toward the sideward arms followed by the ground brace pivoting at PB-E and moving inwardly along path E in the direction of E′ toward the primary canopy to attain an overall compact arrangement of the moveable frame assembly to the likes shown in  FIG.  27   . An end cap  92   c  of the type shown in  FIG.  21    may be fitted to the second end  92   b  of each of the lower outward members to offer protection of the sideward arm as it comes in proximity to the upright support  88 . Conversely, in fulfilling expansion of the movable frame assembly  18  to the likes shown in  FIGS.  30   , the arm-encompassing sleeve  190  of the slidable yoke assembly are slidably moved in the direction of A″ downwardly along the sideward arms  100  toward the outward end  100   c  thereof to the extent of intercepting one of a plurality of settable stops  292  desirably set and located about the length of the sideward arm, mainly represented by a cross pin  292   a  or like structure, whereby the sideward arms move outwardly from the supportive wind wall  84  along path B in the direction of B″ while the primary and secondary canopies respectively move and unfold along paths C and D in the direction of C″ and D″ to the extent of reaching the maximum, desirable length of limiting straps  294  individually mounting to and extending from each of the primary and secondary canopies to the sideward arms, as typically illustrated in  FIG.  24   . Approximately at the same time, the ground brace  148  will move outwardly from the primary canopy along path E in the direction of E″ and continue to unfold to the extent that the cross member  178  of the ground brace engages the ground&#39;s surface. 
     In an alternative instance of using telescopic supports  202  for effecting manual movement of the moveable frame assembly  18 , overall operability of the sideward arms, primary and secondary canopies, and ground brace occurs in like manner described above for the angular moveable supports  182 , primarily about their respective pivots, but differs with respect to the manner in which the telescopic supports operate in relation to the sideward arms. In this regard, the spring-loaded pin  216   c  is depressed and released from its mating aperture  210   c  to allow the inner slidable support  208  to freely and slidably move inward within the elongate sleeve  210 , which simultaneously allows the sideward arms  100 , primary and secondary canopies and ground brace to collectively move and collapse inwardly toward the supportive wind wall  84 . Conversely, expansion of the movable frame assembly simply involves depression of the spring-loaded pin and manually applying an outward force to the sideward arms to extent of attaining a desirable position away and apart from the supportive wind wall, whereupon the canopies and ground brace will collectively unfold with the connected primary shelter shell while the spring-loaded pin is permitted to engage with one of the selected apertures such to lock the moveable frame assembly in place. 
     In using either the angular moveable supports  182  or telescopic supports to effect movement of the moveable frame assembly  18 , consideration is given to the lower wind wall  86  in instances of storage and use of the portable shelter  10 . Untightening the handle  130  allows the supportive framed structure  114  to freely pivot at PB-A and travel along path A and move inwardly and outwardly respectively in the direction of A′ and A″ toward and away from the supportive wind wall to assistively attain overall compactness and expansion of the moveable frame assembly. 
     In an optional configuration of the portable shelter  10 , as generally depicted in  FIG.  66   , a pair of telescopic support poles  296  may be used in lieu of or in conjunction with the lower wind wall  86  to supplement overall support to the moveable frame assembly  18  and advance options for connecting the primary shelter shell  224 . Like the telescopic supports  202  in terms of overall features and function, as operably associated with the sideward arms, each of the telescopic support poles as in  FIGS.  67  and  68    includes a lengthened sleeve  298  for housing and slidably accepting a portion of an elongate member  300 . An open end  298   a  of the lengthened sleeve includes a fitted bushing  302  configured with an opening  302   a  to permit select passage of the elongate member, whereas an open end  300   a  of the elongate member is fitted with an insertable end  304   a  of a stop mechanism  304 , of which is configured with a pin  304   b  of conventional form or equivalent structure for engaging with one of a plurality of apertures  298   b  extending through a wall section  298   c  of the lengthened sleeve. By and through the act of disengaging and engaging the pin at the appropriate or pre-select aperture advances fixed connectivity of the lengthened sleeve  298  with that of the elongate member  300 , particularly being advantageous in setting the overall length of the telescopic support poles to aptly correspond with the cross member  178  of the ground brace generally residing relatively at ground&#39;s surface as well as for stowing alongside the moveable frame assembly in contractive form. In other regards, each of the telescopic support poles  296  may be fitted with an end cap  306  and a foot pad  308  respectively at its first and second ends  296   a,    296   b.  Connectivity of each of the telescopic support poles to the moveable frame assembly  18  is preferably advanced by a pair of T-brackets  310  mountable in an opposing manner relatively about the sideward arms  100  by fastening means, such as a bolt and nut assembly  312  or equivalent, generally at a location in between the supportive extending assembly and the secondary canopy  134  collectively connecting to the sideward arms  100 . In fulfilling capabilities for compactness with that of the moveable frame assembly and securement therewith, each of the lower outward arms  92  may be fitted with an in-line plate  314  as in  FIG.  66   , whereby a fixed end  314   a  thereof is attached to the second end  92   b  of the lower outward member  92 , while a free end  314   b  thereof includes aperture  314   c  that aligns with an aperture  100   d  extending through the sideward arm. A spring pin  316  of conventional form is placed within the aligned arrangement of apertures to fulfill a locking relationship of the sidearm arm  100  with that of the supportive wind wall  84 , particularly upon the instance the telescopic support poles are in a retractable relation and abutting the sideward arms in proximity to the upright supports  88 . 
     In a typical, yet preferred approach for protectively encasing and wrapping the portable shelter  10  for storage and transport, the elongate sideward flaps  250  are moved inwardly and folded to cover a majority of the primary shelter shell  224  from behind, whereby hook-and-loop fasteners  250   a  existing along an outer leading edge  250   b  engagingly mate with one another, while ends  288   a  of the elongate straps  288  are secured together by the buckle  290   a  or equivalent. Subsequently, a pair of lower elongate straps  318  each connectively extending from the elongate sideward flaps  250  are positioned to engagingly mate with a buckle and strap assembly  320  associated with the pair of bottom panels  256 . In completing encapsulation of the contracted moveable frame assembly, the extending top flap  234  is downwardly folded over the connected arrangement of the elongate sideward flaps  250  to permit hook-and-loop fasteners  234   a,    250   a  respectively associated with a leading edge  234   b  of the extending top flap and on an exterior surface  250   c  of the elongate sideward flaps to engagingly mate with one another. Comparatively, in instances where the moveable frame assembly  18  is expanded for utilitarian purposes of occupancy, the elongate sideward flaps may be rolled and bounded by one or more sideward straps  322  extending from and connecting to the side panels  242 , whereby fasteners  322   a  such as a buckle or equivalent secures ends of sideward straps for fulfilling compact storage of the elongate sideward flaps alongside the side panels. 
     It is obvious that the components comprising the portable shelter  10  may be fabricated from a variety of materials, providing such selection or use of materials possess the capacity to withstand forces acting thereon throughout its duration of use as well as limiting occurrences of premature failure due to repeated forces acting thereon during contraction and expansion of the moveable frame assembly  18 . Accordingly, it is most desirable, and therefore preferred, to construct the portable shelter  10 , namely, components of the box frame  16  and moveable frame assembly from extruded aluminum, high tensile strength plastic, polymer composites, or an equivalent type of material that meaningfully offers reasonable structural strength for its weight, while limiting the extent by which the components may unacceptably fail due to applied stresses. 
     While there has been shown and described a particular embodiment of the invention, it will be obvious to those skilled in the art that various changes and alterations can be made therein without departing from the invention and, therefore, it is aimed in the appended claims to cover all such changes and alterations which fall within the true spirit and scope of the invention.
