  • hub 1 contains certain specific features as part of its configuration, such features should not, without more, be considered as limiting when determining the scope of the patent property right. Instead, the scope of such property right should be determined by the claims which follow this section of the specification.

  • hub 1 is generally illustrated as having a convex or spherical type major surface, such configuration is employed, in part, to facilitate efficient manufacturing methods of the hub such as by molding when the hub is constructed from plastic(s) or similar type materials (e.g., so that the hub more easily releases from the mold).
  • the convex-type configuration which is illustrated is not necessary to achieve the various functional objects of the invention described herein, and thus, certainly, other configurations may be employed.

  • Each pivot connecting structure generally includes an outer aperture—for example, aperture 13 a (located on the outer surface of the hub, on side 9 b )—and an associated inner aperture—for example, aperture 15 a (located on the inner surface of the recess or cutout 11 a ).

  • a partially threaded screw with an unthreaded shoulder portion e.g., screw 19
  • the shoulder has an outer diameter which approximates, as near as possible, the inner diameter of outer aperture 13 a (see FIG. 2C , e.g., so that transverse or side-to-side type movement of the screw within the aperture is minimized).
  • pivot connecting structure permits frame members or rods to be (preferably pivotally) connected to the hub with a single fastener (e.g., screws as described). Nevertheless, this feature is optional and should not be imposed on the claim scope unless such a feature is otherwise claimed. It is further noted that although the structure of cutout 11 a , and its associated pivot connecting structure located in side 9 a , is repeated in each of polygonal portions or sides 9 b , 9 c , and 9 d , such identically disclosed structures need not be employed to practice the invention (nor is their equal spacing required).

  • FIG. 3 a profile view of a hub 1 is depicted therein showing one type of the many connector types which can be removably attached to the central aperture 23 of the hub (or, effectively permanently, such as by press fitting, for example). More specifically, FIG. 3 illustrates a threadable connector 301 having a button-type head (or rivet type head) to which display panels can be connected. In an embodiment where a stretch fabric-type display panel is employed, for example, the connector 301 can be inserted through an aperture of the stretch fabric panel thereby securely, albeit non-permanently, connecting it.
