| Patent Number: |

| Title: |
Automated Truss Module |
| Abstract: |
An automated truss module for the support, transport and storage of
lighting instruments is comprised of an upper luminaire mounting platform
for mounting the lighting instruments and a separable transport support
fixture. A truss section assembly, capable of being suspended above a
performance area, is comprised of the upper luminaire mounting platform
mounted to a section of box truss by utilizing helical isolators that
provide a study cushion against shock and limit the transfer of vibration
between the upper luminaire mounting platform and the box truss. The truss
section assembly utilizes a motorized drive assembly to facilitate the
transfer of the lighting instruments between a protected transport
position, and a deployed position extending the lighting instruments below
the truss section assembly for operation. Interchangeable adaptors for
accommodating various types of lighting instruments are utilized for
mounting the lighting instruments to the upper luminaire mounting
platform. The transport support fixture may be secured by means of a latch
arrangement to the upper luminaire mounting platform during transportation
and storage of the truss section assembly with the mounted lighting
instruments. The transport support fixture contains interchangeable head
cradles that mate with the external profile of a lighting instrument in
order to minimize the movement of the lighting instruments during
transportation.
