Description:
RELATED APPLICATIONS  
       [0001]    The present invention claims the benefit of U.S. Provisional Application No. 60/390,489 filed Jun. 21, 2002 and entitled “Framework Connection System,” which is hereby incorporated by reference in its entirety. 
     
    
     
       FIELD OF THE INVENTION  
         [0002]    The present invention is related generally to displays having support framework and graphical displays for use as exhibits at trade shows and the like. More particularly, the invention relates to such displays that are dissassemblable and that utilize tubular components to selectively vary the frame configuration.  
         BACKGROUND OF THE INVENTION  
         [0003]    Exhibits for tradeshows and other marketing venues utilize eye catching and informative graphical portions that are intended to inform and present an image to customers or potential customers. A common use will be at convention or exposition halls where perhaps a single day is allocated for each of setup and removal. To create desired attention-getting appeal, such displays can be massive in size and complexity. Moreover such convention space is usually extraordinarily expensive as is labor for set up and take down of the displays. Thus, such displays need to be designed to be easily and quickly erected and taken down. Such constraints often make these displays quite expensive. Moreover, often new fresh designs are desirable.  
           [0004]    Thus it is preferable that the displays are easily reconfigureable allowing at least the structural framework components to be reused in alternate display configurations.  
           [0005]    The above needs have been met to some extent with collapsible frameworks or collapsible trusses, as illustrated with U.S. Pat. No. 6,149,021, and with box frame designs, as illustrated with U.S. patent application Ser. Nos. 09/953,111 and 09/953,113. While all of these systems have their advantages, the collapsible systems cannot support extensive weight and the exposed truss systems present an industrial look. Large diameter tubular framework systems present a very desirable visual alternative. Such systems have been used in trade show type displays but have not had the flexibility and reconfigurability desirable in this type of product line. Generally such large diameter tubular displays must be custom made for a particular design and involve welded connections and very large sections. Currently, such large framework systems are cumbersome and are often designed with one particular configuration in mind. If the members are not welded, they are generally joined using limited fixed joint connections. Predefined and fixed tees, cross bars, elbows, and the like are provided to join members in a particular configuration. An inability to selectively design and setup such steel tubular framework systems is problematic. It would be highly desirable to have a large diameter display utilizing large diameter tubing that is easily reconfigurable and dissassemblable. It would also be desirable to be able to incorporate such large diameter tubing framework systems with existing truss or box frame systems.  
         SUMMARY OF THE INVENTION  
         [0006]    The display of the present invention addresses and solves many of the described problems that innately plague conventional displays. The present invention employs various individual components that are easily interconnectable to provide the end user with a myriad of framework configuration options utilizing large diameter tubing. These components can be selectively connected so that only those components are used that provide the user with the optimal configuration. As such, connectivity options are increased with the selective combination of only those components which are needed to meet the user&#39;s needs. In addition, the relatively simplistic design of the components and locking options of the present invention improves ease of assembly, disassembly, and reconfiguration.  
           [0007]    The framework connection system of the present invention generally comprises a plurality of frame members, preferably tubular, a plurality of end flanges, and a hub system. The hub system can comprise a hub plate assembly and/or a hub casting assembly. In addition, at least one clamp assembly, preferably cylindrical, can be included for circumferential attachment to the outer surface of the frame members to provide for selective removable fastening of various attachments and accessories at positions along the length of the frame members. The hub plate assembly and the hug casting assembly can be connected individually to the frame members, or in combination, to enable selective angular configuration of the frame members to construct a frame construction, such as those commonly utilized in display frame systems.  
           [0008]    An objective and feature of the present invention is the selective use and re-use of common component, such as hub plate and hub assemblies, to provide for variable frame connection configurations. Displays ranging from the simple to the complex are achieved using the same common mateable components.  
           [0009]    Another objective and feature of the present invention is the ability to selectively and modularly connect metallic tubing members, linear and curvilinear, to construct simple and complex frame connection configurations.  
           [0010]    Yet another objective and feature of the present invention is a display constructed of a tubular framework having clean and substantially uninterrupted visual lines, thus avoiding the conventional implementation of cumbersome, bulky, and unappealing hub designs. The present invention provides for substantial circumferential continuity or visual consistency between the frame member and the connected hub assembly.  
           [0011]    Still another objective and feature of embodiments of the present invention is a display constructed of strong and durable steel tubular frame members to allow for increased stability and strength while still permitting selective modular configuration.  
           [0012]    Another objective and feature of embodiment of the present invention is that the various securing members, such as the set screws, provide engagement with the pins of the mating components to correspondingly bring the components into abuttable or confrontable alignment.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS  
       [0058]    Referring primarily to FIGS. 1 a - 21 , the framework connection system  10  in accordance with the present invention generally comprises a plurality of frame members  12 , a plurality of end flanges  14 , a hub plate assembly  16 , and a hub assembly  18 . Various embodiments of the system  10  components, means of connectivity, and configuration options are described and shown in attached Appendix A, which is hereby incorporated by reference in its entirety. The frame members or segments  12  can be tubular steel tubing members, but in alternative embodiments, other materials and shapes can be employed. Each of the end flanges  14  are insertably attachable to at least one end of the frame member  12  such that the flange  14  is fixed within at least a portion of the tubing member  12 . The flanges  14  can be fixed to the end portion of the frame member  12  with a weldment bond to facilitate connectivity with other system  10  components. Other methods and techniques of attachment understood to one skilled in the art are also envisioned.  
         [0059]    Referring to FIGS. 1 a - 3 , and  21 , the frame members  12  of one embodiment can be constructed of cylindrical steel tubing having a central bore therethrough, and include an end portion  21  and end apertures or recesses  22  providing communication into the central bore. Wire management openings can further be included along the outer surface of the members  12  communicating into the central bore to provide wiring and cabling options throughout the framework. The longitudinal length of the frame members  12  define an axis a 1 . The members  12  can be of varying lengths, depending on the needs of the user. Other embodiments can be constructed of plastics other suitable materials, and can be constructed of square or rectangular tubing, or other shapes typically used to form display frame constructions. In one of the tubular embodiments, the members  12  can have an approximate outer diameter of 2½ to 4 inches. This outer diameter is preferably consistent along the entire length of the tubing, with the length being variable depending on the configuration needs of the manufacturer or end user. The tubing wall thickness is preferably in the range of 0.025 to 0.250 inches, but other dimensions are also envisioned for use with the present invention. The members  12  can be straight or linear, as shown in FIG. 2, or arcuate or curvilinear, as shown in FIG. 3.  
         [0060]    The inner diameter for the tubing bore is some size smaller than the outer diameter, for receiving the end flanges  14 , with the end flanges  14  defining an axis a 2 . The end flanges  14  include a body portion  23  and a face portion  27 . The face portion  27  is generally cylindrical to match the shape of the end portion  21  of the frame members  12  such that the face  27  of the flange  14  substantially lines up with the end of the frame member  12 , or is measurably inset, aligning axis a 1  and a 2 . The flanges  14  can further include a central aperture or recess  24 , a body aperture or recess  25 , and a plurality of indexing or alignment apertures or recesses  26 . Additionally, a plurality of indexing or alignment pins  28  selectively securable within the indexing apertures  26  can be provided. At least one connector pin  30 , and at least one connector fastener  32  can be included as well. The connector pin  30  can include at least one securement groove  31  proximate at least one end of the pin  30 . The connector pins referred to herein can be a one piece pin  30 , or two distinct but joinable pins  42 ,  44 , wherein one pin, i.e., pin  42 , comprises male threading, and a second pin, i.e., pin  44 , comprises female threading to facilitate connectivity. The longitudinal length of each pin  30 ,  42 ,  44  defines an axis a 4 . Various components may require pin  30 , others may require the connected combination of pins  42 ,  44 , and yet others may only require the threadable insertion of pin  42 . Regardless, reference herein to any of the referenced pins  30 ,  42 ,  44  is merely demonstrative as any one of the pins can provide the requisite connectivity described. Alternative embodiments of the pins  30 ,  42 ,  44  can take on various shapes, such as hexagonal or other non-cylindrical forms, along at least a portion of the longitudinal length. As such, the flats or edges of the non-cylindrical pin  30  are mateably inserted into the flange  14  central aperture  24  having a substantially similar shape such that rotation of the confronting tubing members  12  along the common axis a 1  is limited as shown in FIG. 1 e.    
         [0061]    Referring to FIGS. 1 d - 1   e , and  4 - 5 , the central aperture  24  traverses at least a portion of the face  27  of the flange  14  some distance inward through the body  23 . The body aperture  25  traverses into the body  23  transverse or radial to the central aperture  24  such that the apertures  24 ,  25  are in fluid communication with each other. The body aperture  25  can further include a lip proximate the point of communication with the central aperture  24  to provide a stop for an inserted connector pin  30 . When secured within the end portion  21  of the frame member  12 , the body aperture  25  of the flange  14  is substantially aligned with the end aperture  22  of the frame member  12  such that a fastener, i.e., the at least one connector fastener  32 , is insertable through both apertures  22 ,  25 , radially in relation to axis a 1  and a 2 , to fasten the connector pin  30  in place at the securement groove  31 . The central aperture  24  and the body aperture  24  can be threaded for receipt of various fasteners and/or pins for component connectivity.  
         [0062]    The indexing apertures  26  can also include a threading portion for receipt of the plurality of indexing pins  28 . Preferably, the indexing apertures  26  are located along the face  27  of the flange  14 , traverse in some distance through the face  27 , and are spaced at predetermined intervals following the diametrical face  27  of the flange  14  to provide for various lockable engagement options. The receivable indexing pins  28  can include a threaded portion to engage corresponding threading in the indexing apertures  26 . The indexing pins  28  can provide for needed stability when insertably aligned within those components having index receiving apertures. The primary stability function of the indexing pins  28  is to limit rotation of the member  12  in relation to interlocked components—i.e., another axially connected frame member  12  with flange  14 , or a connected hub assembly  18  as shown in FIGS. 1 d - 1   e , and  21 . Rotational movement about the longitudinal axis a 1  of the member  12  is restricted by the interlocked indexing pins  28 .  
         [0063]    A limited portion of the connector pin  30  can be inserted into the central aperture  24 , aligning axis a 2  and a 4 , such that one of the grooves  31  is alignable with at least one of the end apertures  22  of the frame member  12 . The connector fastener  32  is shaped and sized to be removably threaded into the end aperture  22  and through the body aperture  25  of the flange  14 , radially in relation to axis a 2  and a 4 , to securably engage the groove  31  of the connector pin  30 , pulling or drawing the connector pin and the engaging component (i.e., a hub or frame member) into abuttable securement with the flange  14 . The at least one connector fastener  32  can be a set screw, or other fastening means known to one skilled in the art for selectively engaging or locking with such a pin  30 . Bolts, screws, and a myriad of other fasteners and fastening means are envisioned for use throughout the present invention when component connectivity is required. The various setscrew fasteners of the present invention can be easily adjustably threaded into the respective apertures or recesses utilizing a setscrew wrench, such as that shown in FIG. 21.  
         [0064]    Referring primarily to FIGS.  8 - 9 , the hub plate assembly  16  can include a hub plate  33  having at least one connecting branch  34 . The plate  33  can further include a plurality of index receiving apertures or recesses  36 , and a central plate aperture or recess  38 . Each of the connecting branches  34  of the hub plate  33  can include a plurality of branch apertures or recesses  40 . The branch apertures  40  can completely pass through the branch  34 ; or they can define dimpled depressions in the branches  34 . The hub-plate assembly  16  can further include a first plate connector pin  42  and a second plate connector pin  44 , or alternatively, a single unitary-bodied pin. Preferably, the plate connector pins  42 ,  44  are removably connectable to one another through the central aperture  38 . This connectivity option can be achieved with the use of a threaded portion, wherein one of the pins includes a female threaded portion and the other pin includes a mail threaded portion, and the connectivity of the pins  42 ,  44  leaves a non-threaded portion of each pin, and axis a 4 , extending out transverse from the plane of the plate  33 . Other known connection methods and techniques are also envisioned.  
         [0065]    The hub plate  33  generally has a circular inner portion  35  preferably integral with the at least one connecting branch  34  such that the at least one branch  34  extends out from the inner portion  35  substantially along the same plane. The indexing apertures  36  are preferably spaced around the central aperture  38  through the circular inner portion  35  and are adapted to receive the indexing pins  28  for selective lockable engagement, as demonstrated in FIG. 1 d.  Embodiments of the hub plate  33  will employ varying branch  34  options, at varying angular configurations. For instance, one embodiment will include a single branch  34 , as shown in FIG. 8. Other embodiments will include the angular branch  34  options shown in FIGS. 13 and 20. As the figures show, specific embodiments include connecting branches  34  extending away from the inner portion  35  of the hub plate  33  at ninety degree increments, while other embodiments include one-hundred-twenty degree and one-hundred-thirty-five degree increments. A myriad of angular branch  34  configurations in addition to those shown can be employed without deviating from the spirit and scope of the present invention.  
         [0066]    Referring to FIGS.  6 - 7 , and  10 - 13 , embodiments of the hub assembly  18  are shown. The hub assembly  18  generally comprises a hub  46 , and at least one connector fastener  60 . The hub  46  can include a central hub aperture or recess  48 , a plurality of index receiving apertures or recesses  50 , at least one fastening aperture or recess  52 , a receiving slot  54 , at least one hub contour  56 , and a hub face portion  58 . In one embodiment, the hub  46  is generally cylindrical in cross-section (for certain cylindrical tubular frame member  12  systems), defines an axis a 3 , and is adapted for connection to the frame member  12  by selectively securing a grooved portion  31  of the connector pins  30 ,  42  through the central hub aperture  48  with the connector fastener  60 . Alternatively, the connector pin  42  can include a threaded portion threadably insertable into a mateable threaded central hub aperture  48  such that the groove portion  31  extends out from the hub face portion  58 . Like the connector fastener  32  for the end flange  14 , the connector fastener  60  of the hub assembly  18  can be a setscrew or like fastening means. As described herein, the other grooved portion  31  of the pin  42  is secured by the connector fastener  32  through the end aperture  22  of the frame member  12  and through the aligned body aperture  25  of the flange  14  such that it engages and selectively locks the connector pin  42  in place within the flange  14 . As such, the hub  46  is lockably engaged to the end portion  21  of the frame member  12  at the end flange  14 , thus aligning axis a 1  and a 3 , as best demonstrated in FIGS. 1 d - 1   e , and  21 . This connection results in the receiving slot  54  facing out from the frame member  12 .  
         [0067]    In one configuration, the index receiving apertures  50  are located on, and pass through, the face portion  58  of the hub  46  for receivable alignment with the indexing pins  28  of the end flanges  14 , or other components. The fastening apertures  52  pass through the outer circumferential surface of the hub  46 , through the hub  46 , and into communication with the central aperture  48  and the receiving slot  54 . The receiving slot  54  passes through the central axis of the hub  46 , at the portion of the hub  46  distal the face portion  58  and traverses a distance into the hub  46  short of the face portion  58 . The slot  54  is generally sized and shaped so that it is capable of slidably receiving the at least one branch  34  of the hub plate  33 , as demonstrated in FIGS.  10 - 13 . Once received and positioned, at least one of the branch apertures  40  of the respective branch  34  is aligned and in communication with the fastening apertures  52  of the hub  46 , wherein a connector fastener  60 , such as is demonstrated in FIG. 13, locks the branch  34  in place. The at least one hub contour  56  is sized and shaped to enable confronting slidable engagement with the at least a portion of the outer circumferential surface of corresponding tubular frame members  12 , as shown in FIGS. 1 d - 1   e . As best demonstrated in FIGS. 1 d,  and  19 - 21 , the contours  56  of multiple hubs  46  interlocked around the connecting braches  34  of the intermediate hub plate  33  provide sufficient spacing for receiving the flange  14  and indexing pins  28  of a respective transversely or radially aligned frame member  12 .  
         [0068]    The present invention  10  can further include corner joint assemblies  100 , such as a fixed corner assembly  102  and/or a pivot corner assembly  104 , as shown in FIGS.  14 - 18 . The fixed corner assembly  102  of FIGS.  14 - 15  can include a fixed base portion  106  and a fixed angle portion  112 . The fixed base portion  106  includes a plurality of base indexing apertures or recesses  108 , a concave portion  109 , and a central aperture or recess  110 . The fixed angle portion  112  includes a corner face portion  114 , a plurality of angle portion indexing apertures or recesses  1   16 , and an angle portion central aperture or recess  117 . The fixed angle portion  112 , in one embodiment, is oriented substantially ninety degrees from the axis of the fixed base portion  106 . Other fixed angles between the angle portion  112  and the base portion  106  are envisioned in alternative embodiments. The base indexing apertures  108  and the angle portion indexing apertures  116  are both adapted to receive the indexing pins  28  of the end flanges  14  to provide selective engagement of the fixed corner  102  to respective frame members  12  to provide angular corner portions in a design frame construction. Similarly, the central apertures  110 ,  117  of the fixed corner assembly  102  are capable of receiving connector pins  30 ,  42  for further securement at one end within the central aperture  24  of respective end flanges  14  for attachment using the connector fastener  32  and methods described herein. The concave portion  109  is sized and shaped to compatibly confront at least a portion of the outer circumferential surface of a respective frame member  12  upon connection of the end flange  14  to the fixed angle portion  112 , as demonstrated in FIG. 15. Indexing pins  28  are also used as with any component capable of lockable engagement with the flange  14  of a frame member  12 .  
         [0069]    The pivot corner assembly  104  of FIGS.  16 - 18  can include a pivot base portion  120 , and a pivot arm  132 . Locking interval pins  140  can also be included. The pivot base portion  120  can include pivot base first indexing apertures or recesses  122 , a pivot base central aperture or recess  124 , a pivot base concave portion  126 , a pivot base axial groove  128 , and pivot base second indexing apertures or recesses  130 . The pivot arm  132  includes a pivot aperture or recess  134 , a pivot central aperture or recess  135 , a pivoting device  136 , and pivot arm indexing apertures or recesses  138 . The pivot arm  132  is capable of pivotable movement around the pivot device  136  for selective angular configurations. When a specific angular setting is obtained, the pivot device  136 , such as a pin, screw, bolt, and the like is lockably secured to temporarily fix the pivot arm  136  at the desired angle. In the embodiment of FIG. 16, the locking interval pins  140  are insertable into a portion of the pivot arm  136  to further stabilize the pivot arm  36  upon setting the arm  136  to the desired angle. These locking interval pins  140  are generally insertable into groove apertures or recesses  129  within the axial groove  128  of the base portion  120 , and can provide predefined, but selective, angular configurations for the pivot arm  136  of approximately zero degrees, forty-five degrees, and ninety-degree increments. Other predefined angular options are also envisioned. Without the interval pins  140 , the arm  136  is capable of adjustment along a myriad of angular settings. Again, the central apertures  124 ,  135  of the pivot corner assembly  104  are capable of receiving connector pins  30 ,  42  for further securement at one end within the central aperture  24  of respective end flanges  14  for attachment using the connector fastener  32  and methods described herein. The concave portion  126  defines a curved surface allowing the end of the pivot arm  136 , distal the pivot central aperture  135 , free pivoting movement. Indexing pins  28  are also used as with any component capable of lockable engagement with the flange  14  of a frame member  12 .  
         [0070]    Referring primarily to FIGS.  19 - 31 , various plates, caps, end plates, and like components can be attached to frame member  12  end portions  21  via the versatile and modular end flange  14  design and/or the hub plate  33 . For instance, FIGS.  19 - 21  show the implementation of an end filler cap  80  attachable to the hub plate  33  which is thereby secured to the flange  14  of the frame member  12 . The end filler cap  80  can include at least one cap aperture or recess  81 , and a plurality of cap indexing apertures or recesses  81   a . The at least one cap aperture  81  can receive any one of the connecting pins  30 ,  42  to provide coupleable engagement with the hub plate central aperture  38  and the central aperture  24  of the flange  14 . The connecting pin, preferably one of the two joinable pins  42 ,  44 , is then locked in place with the connector fastener  32  through the end aperture  22  of the frame member  12 . Again, the indexing pins  28  can provide rotational stability. The cap indexing apertures  81   a  can receive one end of the indexing pins  28  while the other is aligned with an indexing aperture  26  of the flange  14 . End filler caps  80  of the present embodiment can increase aesthetic appeal by closing off exposed hub  18  and hub plate  16  components. Further, the end filler caps  80  can increase stability and strength of frame member  12  junctures by filling in the voids between the hub  18  and hub plate  16  assemblies. The hub contours  56  of proximate hub assemblies  18  in a hub juncture, such as those shown in FIGS.  19 - 21 , are each generally shaped and sized to engage a portion of the circumferential surface of the end filler cap  80 .  
         [0071]    Various end caps  150   a,    150   b  can also be employed with the present invention to cap off exposed flanges  14  of the members  12 . For instance, FIGS.  22 - 25  show two embodiments of the end caps  150   a,    150   b  coupled in such a manner. FIGS.  22 - 23  show a large end cap  150   a  the cap  150   a  including a cap aperture or recess  152  for securably receiving one of the connector pins  42 ,  44  for insertion into the central aperture  24  of the flange  14 . In a preferred embodiment, a pin  42  having male threading at one end is threadably secured within the cap aperture  25  such that a grooved end  31  of the pin  42  is insertable within the central aperture  24  of the flange  14 . As such, fastener  32  engages the groove  31  of the connector pin  42  through the end aperture  22  of the frame member  12  to selectively lock the cap  150   a  in place. In addition, indexing pins  28  within the indexing apertures  26  of the flange  14  can be inserted into aligned apertures in the cap  150   a  to provide rotational stability. FIGS.  24 - 25  show a thin end cap  150   b,  wherein the,end cap  150   b  includes the cap aperture  152  for threadably receiving the threaded connector pin  42 . Again, a grooved portion  31  of the connector pin  42  is insertable within the central aperture  24  of the flange  14  to provide selective lockable engagement with fastener  32  through end aperture  22  of the frame member  12 . In at least one embodiment, this relatively thin end cap  150   b  embodiment does not utilize indexing pins  28 . Aesthetic appeal and functionality are enhanced with each of the end caps  150   a,    150   b.    
         [0072]    To facilitate standing frameworks, it may be necessary to include various stands, feet, pods and other supporting members at end portions of particular frame members  12 . FIGS.  26 - 31  demonstrate embodiments of these supporting members adapted for implementation with the present invention. In FIGS.  26 - 27  a base stand  154  including a base stand coupling  156  is shown for use with the present invention. The base stand  154  is generally disc shaped and can be of varying sizes depending on the support needs of the particular framework configuration. Other shapes and proportional configurations are envisioned as well. The base stand coupling  156  is connectably positioned on the base stand  154  for lockable engagement with the hub plate  33  of the hub plate assembly  16  or the flange  14  of the frame member  12 . When connected to the hub plate  33 , connector pin  42  can be insertable within the flange  14  central aperture  24 , while the other connector pin  44  is insertable into the base standing coupling through a centrally traversing coupling aperture  158 . A side stand fastening aperture  160  transverse to, but in communication with, the coupling aperture  158  can be included for receiving the connector fastener  60  to lock the base stand  154  against the grooved portion  31  of the inserted pin  44 . Indexing pin  28  can be utilized to further secure the base stand  154  to the hub plate assembly  16  for increased rotational stability.  
         [0073]    Referring primarily to FIGS.  27 - 29 , and  31 , a foot pod system  162  is shown. The foot pod system  162  includes a base pod  164 , a base cap  166 , and at least one pod fastener  168 . The base pod  164  is generally disk shaped and includes a threaded shaft  165  extending out from the pod  164 . The base cap  166  can include a plurality of base cap apertures or recesses  170 . In attaching the foot pod  162  to the flange  14  of the frame member  12 , the hub plate  33  is positionally aligned intermediate the flange  14  and the base cap  166  such that the pod fasteners  168  can be inserted up into the base cap apertures  170 , through the index receiving apertures  36  of the hub plate  33 , and into the indexing apertures  26  of the flange  14 , as best shown in FIG. 28. Upon alignment, the fasteners  168  can be tightened to fasten the base cap  166  to the hub plate  33  at the end portion  21  of the frame member  12 . The threaded shaft  165  of the base pod  164  can then be threadably inserted and secured within one of the base cap apertures  170 , as shown in FIG. 29. As such, a support stand or pod is provided at the end of the respective frame member  12  to increase stability and support for the framework system  10 . FIG. 31 shows another view of an embodiment of the foot pod system  162 , with base cap  166 , being connected through to the hub plate  33  of a two hub assembly  18  system.  
         [0074]    An alternate embodiment of the foot pod system  162  is included in FIG. 30. This embodiment includes the base pod  154  and corresponding threaded shaft  165 . However, connectivity with the frame member  12  can be achieved without the base cap  166  or intermediate hub plate  33 . To facilitate this connection to the flange  14  of the frame member  14 , the threaded shaft  165  can further include an end ball joint  176 , and a longitudinally threadably adjustable elongate nut  172  having an intermediate groove  174 . The elongate nut  172  is insertable along with the threaded shaft  165  into the central aperture  24  of the flange  14 , along aligned axis a 1  and a 2 , wherein the fastener  32 , such as the setscrew  32 , can secure the foot pod  162  in place by engaging the intermediate groove  174  of the elongate nut  172 . Longitudinal adjustments of the elongate nut  172  along the length of the threaded shaft  165  provide for selective height adjustments for the pod  162  in relation to the respective frame member  12 . The ball joint  176  is at least partially shrouded within the base pod  164  to enable angular adjustments of the shaft  165  in relation to the base pod  164 .  
         [0075]    Referring to FIGS.  32 - 36 , the framework connection system  10  can further include a clamp assembly  20 . In one embodiment, the clamp assembly  20  can include a first clamp  62 , a second clamp  64 , and lock fasteners  68 , with each clamp including locking channels  66 , attachment apertures  70 , inner circumferential surfaces  72 , outer circumferential surfaces  76 , and an inner attachment lining  74 . In those embodiments utilizing cylindrical tubing frame members  12 , the clamp assembly  20  is substantially cylindrical, with the inner surface  72  sized and shaped for confronting engagement around the outside surface of the frame members  12 . In addition, the outer circumferential surfaces  76  of the clamps  62 ,  64  can include surface flats  76   a.  Any surface of the clamps  62 ,  64  can include the attachment apertures  70 , including the flats  76   a . Unlike conventional clamping devices, the clamp assembly  20  of the present invention permits selective placement and removal of the claim assembly  20  along the length of the frame member  12  without the need to remove all frame attachments or appurtenances. The clamp portions  62 ,  64  can be separated and removed, wherein conventional unitary-bodied clamps require users to slide the clamp off an end portion of the frame member after removing each shelf, lamp, or other appurtenance that may be positioned between the clamp and the end of the frame member.  
         [0076]    The first clamp  62  and the second clamp  64  are joined at the confronting locking channels  66  of the respective clamps  62 ,  64  for selective engagement with a corresponding frame member  12 . The locking fasteners  68 , such as screws, bolts, and like means are inserted into the channels  66  to secure the clamps  62 ,  64  together around the frame member  12 . Other locking means known to one skilled in the art can also be employed.  
         [0077]    The inner attachment lining  74  is generally positioned along the inner circumferential surfaces  72  of the clamps  62 ,  64 , and as a result, can include two separate linings  74 . The lining  72  can serve many purposes, such as minimizing damage to the frame member  12  during the positioning, adjusting, and removing of the clamp assembly  20  from the frame members  12 ,.and to facilitate attachment. In one embodiment, the attachment lining  74  can be constructed of plastics, rubbers, or other like materials to protect the surfaces of the clamp assembly  20  and the engaged frame member  12  from scratching, and to provide effective slidability. In another embodiment, the lining  74  is constructed of a magnetic material or member to facilitate ease-of-attachment and stability during use. In both embodiments, the lining  74  can be attached to the inner surfaces  72  of the clamps  62 ,  64  with adhesives or other known bonding techniques and means.  
         [0078]    Various other embodiments of the clamp assembly  20 , with one such embodiment shown in FIG. 32 a,  will include a hinge device  67 , wherein the first clamp  62  includes a first hinge portion  67   a  and the second clamp  64  includes a second hinge portion  67   b.  Generally, one of the respective first and second clamp locking channels  66  and locking fasteners  68  are replaced with the hinge  67  and the corresponding hinge portions  67   a,    67   b.  The corresponding hinge portions  67   a,    67   b  are pivotably mateable with a member such a hinge pivot pin  69  therethrough. The hinge  67  provides a pivoting joint connecting the clamps  62 ,  64  for selective rotational adjustment of the clamps  62 ,  64  in relation to each other to facilitate placement on and removal of the assembly  20  from the frame members  12 . Tab receiving recesses  71  can be included for attaching the inner lining  74 , as shown in FIG. 32 a.  However, other hinged embodiments of the clamp assembly  20  will connect a liner, magnetic member, and the like to the inner circumferential surface  72  of at least one of the clamps  62 ,  64  using the. adhesive or other bonding techniques and methods described herein.  
         [0079]    A myriad of frame system attachments arid appurtenances  178  can be secured to the frame members  12  by way of the clamp assembly  20  and the attachment apertures  70 , as shown in FIGS.  34 - 36 . For instance appurtenances  178  such as computer monitor support bars, screen attachment tubing and apparatus, lighting, banner connectors, shelves, literature racks, plasma supports, support brackets, CPU cabinets, keyboard tables, counters, and like components and accessories systems can be selectively attached to the attachment apertures  70  of the clamp assembly  20 . Referring to FIG. 34, a collar frame connector assembly  180  is shown. The collar assembly  180  generally includes at least one collar bracket  190  secured to the attachment apertures  70 , and a linking assembly  192 . The collar assembly  180 , and the linking assembly  192  in particular, are adapted to lockably engage the flange  14  of a frame member  12  to provide an additional connectivity option for the present invention.  
         [0080]    [0080]FIG. 35 shows two clamp assemblies  20  spaced along the length of the frame member  12  to provide support for a display mounting assembly  182 , such as those used to support computer displays and plasma screens. The display mounting assembly  182  can include a frame assembly and connecting brackets  186 , wherein the brackets  186  are secured to the attachment apertures  70  of the clamp assembly  20 . FIG. 36 demonstrates how a clamp assembly  20  can be utilized to secure a counter appurtenance  190  to the framework system at selective locations along the length of a frame member  12 . The counter or shelf  190  is positioned to rest upon the clamp assembly  20  and secured into at least one of the clamps  62 ,  64  through the attachment apertures.  
         [0081]    FIGS.  37 - 38  show a bracket device  192  which can include a central body portion  194 , at least one bracket branch  196 , bracket indexing apertures  198 , and a bracket central aperture  200 . Connector blocks  202  can also be included to provide modular connectivity for other tubing members, such as those tubing segments, members, and devices disclosed and taught in U.S. patent application Ser. Nos. 09/953,113 and 09/953,111, which are hereby incorporated by reference in their entirety. Other connectors or small tubing segments can be joined to the bracket device  92  using various connections, such as clips, snaps, tracks, and like connection means without deviating from the spirit and scope of the present invention. The branch  196  can be elongate branches as shown in FIGS.  37 - 38 , or they can take the form of clips or other connectors. In addition, a plurality of branches  196  can be employed, at various angles with respect to the central portion  194  and other branches  196 . The central body portion  194  is preferably sized and shaped for intermediate positioning and securement between two frame members  12  and their corresponding flanges  14  with the bracket branch  196  extending some distance out transverse or radial to the axis a 1  of the frame members  12 . As such, the bracket central aperture  200  and the bracket indexing apertures are adapted to intermediately receive the connector pin  30 ,  42  and indexing pins  28 , respectively, as demonstrated in FIG. 37. Upon securement of the end portions  21  and flanges  14  of the confronting frame members  12 , the bracket device  192  is locked into place.  
         [0082]    The system  10  of the present invention can further include various assemblies and connection components adapted to facilitate compatible interconnectivity with other framing systems. For instance, an end plate  82  assembly, as in FIGS.  39 - 40 , having a plurality of receiving apertures or recesses  83  can be included to connection to box frame assemblies such as the system described and disclosed in previously incorporated U.S. patent application Ser. Nos. 09/953,113 and 09/953,111. The receiving apertures  83  can be spaced to match corresponding box frame trusses or other frame members on one side, and aligned for lockable connection with indexing pins  28  and/or the connector pin  42  of the end flanges  14  on the other side. Connectors, such as the connector blocks  202 , can be secured to appropriate portions of at least one side of the end plate  82  to facilitate connection to the other frame members. As shown in FIG. 39, and as described herein, the connector pin  30 ,  42  can be threaded at one end for attachment to the end plate assembly  82 . Other embodiments may weld the plate  82  to the frame members  12 , or implement a myriad of other attachment techniques and methods. With such a configuration it is possible to join frame systems having very different shapes and structural characteristics, such as the joining of cylindrical tubing framing systems to square tubing box frame systems. Other possible combinations and end plate shapes are envisioned for joining frame systems having different shapes.  
         [0083]    Referring primarily to FIGS. 1 d - 1   e,  and  21 , in use the framework connection system  10  of the present invention provides the end user with a wide variety of angular configuration options using selective combinations of one or more of the end flanges  13 , the hub plate assemblies  16 , and the hub assemblies  18 . The following examples are merely to provide instruction on some of the potential permutations available to the end user, and are not intended to be at all exhaustive.  
         [0084]    In one embodiment, the system  10  can be quite simplistic in its configuration by providing for a direct connection of two axially aligned frame members  12 . With such a configuration, the connector pin  30  having two substantially identical ends with grooves  31 , is inserted into the central apertures  24  of the respective flanges  14  along axis a 2 , wherein connector fasteners  32  are inserted through the end apertures  22  of the frame members  12  to removably lock the frame members  12  abuttably together. The connector fasteners  32  engage the grooves  31  of respective end portions of connector pin  30  to achieve engagement in one embodiment. The indexing pins  28  can be included within the indexing apertures  26  of abutting flanges  14  to provide rotational stability. A plurality of these frame members  12 , straight or curvilinear, can be connected one after the other in series.  
         [0085]    In other embodiments, as demonstrated in FIGS. 1 d - 1   e , and  21 , the hub plate  33  and corresponding connecting branches  34  are connectable to hub assemblies  18  to further increase the angular configuration options of the system. Generally speaking, a corresponding hub  46  and hub assembly  18  is matched with every connecting branch  34  of the subject hub plate  33  such that the hub plate  33 , and the inner portion  35  in particular, interpose the hubs  46 . The branches  34  are slidably received in the receiving slots  54  of the hubs  46 . In those embodiments wherein the branches  34  are positioned at ninety-degree intervals, this will result in a maximum of four angular options along the plane of the plate  33 , for each plate  33  integrated into the system  10 . For instance, as shown best in FIGS. 1 d,  a three-way hub plate assembly  16  can be included, wherein the three hub plate  33  connecting branches  34  are connectable to three transversely aligned respective hub assemblies  18  via the hub receiving slots  52 . In turn, the hub assemblies  16 , at the end opposite the receiving slots  52 , are locked with connector pins  30 ,  42 , and/or aligned with the indexing pins  28 , to axially align the hub assemblies  16  with the respective flanges  14  of the frame members  12  along axis a 1  and a 2 . Further, two frame members  12  can be lockably secured to the inner portion  35  of the hub plate  33 , transverse to the plane of the plate  33 , using the plate connector pins  42 ,  44 . With such a configuration, a five member  12  juncture is created. Alternatively, a filler cap  80  can be inserted to fill in the exposed inner portion  35  of the plate  33 .  
         [0086]    Similarly, if a four branch  34  hub plate  33  is employed, it is possible to create a six member  12  juncture. Even a rather simple one way branch  34  hub plate assembly  16  can provide for a three member  12  juncture with the attachment of the hub  46  to the one branch  34 , and the transverse attachment of two additional members  12  at the inner portion  35  of the plate  33 . Moreover, clamp assemblies  20 , filler caps  80 , end plates  82 , corner joints  100 , base stands  154 , foot pods  162  and other components and assemblies can substitute for, or be incorporated with, the members  12 . It should be obvious to one skilled in the art that the removal, addition, and the selective combination of various system components leaves the end user with a multitude of angular, functional, and aesthetic configuration options, of which only a few have been described to merely advance an understanding of the advantages of the present invention. Combining the selective modular configuration of system  10  of the present invention with other appurtenances  178 , screens, and components and systems known to one skilled in the art for use with display frameworks are demonstrated in FIGS. 1 a - 1   c.    
         [0087]    Although the invention herein has been described by way of examples of preferred and alternative demonstrative embodiments, it will be evident that other adaptations and modifications may be employed without departing from the spirit and scope of the present invention. The terms and expressions employed herein have been used as terms of description and not of limitation. There is no intent to exclude equivalents and selective combinations, and it is intended that the description cover any and all equivalents that may be employed without departing from the spirit and scope of the invention.
