Claims15
A cargo lowering slide assembly comprising:
- a first slide assembly having at least a first slide rail and a second slide rail, the second slide rail interconnected and substantially parallel to the first slide rail, wherein the second slide rail is configured to slidably extend and retract longitudinally in relation to the first slide rail;
- the first slide rail having a spur gear axially interconnected with the first slide rail, and the second slide rail having a rack gear, wherein the spur gear of the first slide rail is intermeshed with the rack gear of the second slide rail, and wherein the rotation of the spur gear in a first direction extends the first slide assembly toward an extended configuration and wherein the rotation of the spur gear in a second direction retracts the first slide assembly toward a retracted configuration;
- a first scissor lift assembly comprising a scissors mechanism, the scissors mechanism comprising at least one scissors linkage with a first end comprising a pivoting connection and a sliding connection with the first slide assembly;
- the scissors mechanism further comprising a second end having a pivoting connection and a sliding connection with a cargo platform;
- a first cable lift assembly interconnected to the first slide assembly, the first cable lift assembly comprising a drum having a longitudinal axis substantially perpendicular to the direction of travel of the scissor lift assembly;
- and
- the first cable lift assembly further comprising a cable interconnected with the drum and interconnected with the scissor lift assembly or the cargo platform, wherein the rotation of the drum in a first direction lowers the cargo platform toward a lowered configuration, and wherein the rotation of the drum in a second direction raises the cargo platform toward a raised configuration.
