发明名称 Step Device for Accessing a Truck Bed
摘要 A step device for accessing a truck bed according to the present invention includes a telescopic boom assembly that is movable between retracted and extended configurations. A first end of the boom assembly may be coupled to the frame of a truck. The step device may be hidden from view beneath the truck bed at the retracted configuration. The step device also includes a plurality of steps movable between collapsed and deployed configurations. A linkage couples at least one of the steps with the boom assembly such that the steps are moved between collapsed and deployed configurations as the boom assembly is moved between retracted and extended configurations, respectively. A latch selectively holds the boom assembly at the extended configuration and, when released, a tension member biases the boom member to move to the retracted configuration.
