Abstract
A folding display frame comprises a grid of horizontal and vertical rod members forming an array of three dimensional cubicles. The cubicles have eight corners with a separate hub at each corner of the cubicle. The framework forming each cubicle has a top frame section, a bottom frame section, and two side frame sections. Each frame section is formed by two rods intersecting and pivotally join to each other midway between their ends. The ends of the rods in each cubicle are pivotally attached to corresponding hubs located at each of the corners of the cubicle. Adjacent cubicles in the array share common rods and hubs. Separate diagonal stabilizing members are located within bottom cubicles of the display frame to prevent the cubicles from being distorted into a parallelogram shape when the frame is erected in its fixed position and weight is supported on the front of the frame. Each diagonal stabilizing member comprises a telescoping brace comprised of inner and outer rod members slidable relative to each other to adjust the length of the brace. The rod members have means for restricting their maximum length, and the diagonal braces are mounted within the bottom cubicles so that they act as a restraint in the tension direction to restrict the bottom cubicles from distorting into a parallelogram shape.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
