NASA TECH BRIEF 
This NASA Tech Brief is issued by the Technology Utilization Division to acquaint industry 
with the technical content of an innovation derived from the NASA space program. 
Portable Display Paneling Has Wide Use, Easy Take Down and Assembly 
Bar 
The problem: Design of portable display paneling 
that is sturdy and yet can be taken down easily or 
reassembled. Completed display must be attractive 
and moderate in cost. 
The solution: A modular display panel based on a 
cross-shaped corner connector and wooden lattice 
bars. 
How it's done: The key element in this panel is the 
metal corner connector. For this application it is 
made of two metal stampings so designed that two 
identical pieces can be spot welded together to 
form the connector. Other joining methods, such as 
bolting or riveting, can be employed.
Form of the completed connector is a right-angled 
cross. Arms of the cross are hollow and square in 
cross-section so that a square wooden lattice bar will 
fit into each arm. A circular detent serves to secure 
the bar while an elongated detent acts as a stop. In 
the web between two adjacent arms there is a pocket 
slot to hold a modular-size panel. The display is 
constructed by putting the required number of bars 
and panels together. 
Variations in size, shape and choice of materials 
can be made to suit specific displays. Design is 
such that displays can be curved if desired. Other 
important features are: low cost, sturdiness, and ease 
of rapid assembly and disassembly.

Notes: 
1. This is a highly practical approach to the problem 
of large display panels. It could be useful to 
advertising firms, manufacturers who require dis-
plays at trade shows or other places, and research 
organizations. 
2. Because of the ease of take-down, this display 
greatly simplifies the problems of transportation 
and storage. Space required is much less and only 
simple packing crates are needed.
Display designers will have more flexibility in 
planning a layout. An alternate presentation, for 
example, can be put on the back of the modular 
panels. Position of the panels can be changed so 
that a display could offer a change in appearance 
if moved from one location to another. 
Patent status: NASA encourages commercial use 
of this innovation. No patent action is contemplated.
