| Title: |
Storage and Transportation Trunk for Lighting Equipment |
| Abstract: |
A storage trunk for storing and transporting lighting equipment is
constructed using a rotationally molded cross linked polyethylene plastic.
The storage trunk is comprised of an enclosure body and a separately
removable lid. The lid may be secured to the enclosure body by means of a
plurality of latches. The interior of the enclosure body may be molded as
a generally open rectangular region or may include molded features for
receiving and supporting specific lighting instruments within its
interior. The hollow walls of the molded enclosure body are filled with
polyurethane foam for reinforcing the walls and damping their movement. A
perforated metal stiffening frame is molded into the base of the enclosure
body during the molding process for added strength. The underside of the
enclosure body provides a plurality of casters for easy movement. The
storage trunk features a unitized, seamless construction having no
fasteners or external reinforcements to leak, snag other objects, or fall
off. Various molded recesses, protrusions and surfaces in the storage
trunk serve to enhance the functionality, strength and durability of the
plastic storage trunk. Lateral bearing surfaces that protrude from the
storage trunk minimize the wear on the exterior surfaces of the trunk by
ensuring that the entire surface of the trunk does not contact adjacent
surfaces. The storage trunk is constructed with convoluted end surfaces
having protrusions and recesses that allow adjacent surfaces to interlock
when positioned end to end.
