Abstract: An adjustable rack assembly includes a base frame defining an upper end and an open front side and an extension frame defining an upper end, a bottom end and an open front side. The extension frame is slidably mounted to the base frame. The assembly further includes an actuator coupled between the base frame and the extension frame and operable to move the extension frame between a collapsed position and an extended position. A compartment unit is supported by the extension frame and is at least partially collapsible to accommodate the movement of the extension frame between the collapsed position and the extended position.

Abstract: A transportation rack includes a base frame configured for resting on a surface and including an upper open side and an open front side. The transportation rack further includes an extension frame defining an open front side and being slideably received through the open upper side of the base frame. An actuator is coupled between the base frame and the extension frame and is operable to move the extension frame in an extending direction outwardly from the base frame through the open upper side and a collapsing direction inwardly to the base frame through the open upper side. The transportation rack further includes a compartment unit supported by the extension frame and having a collapsing portion therealong that accommodates the extending and collapsing of the extension frame with respect to the base frame.
