Abstract: Carrying cases are disclosed that include a tray for audio, computer, and/or video components. The tray can include a tray base member coupled to the case and a tray shelf that is movably coupled to the tray base member and configured to support a laptop or other audio, computer, or video component thereon. The tray shelf can be rotatable about a base axis defined by the tray base member, movable axially along the base axis, and/or rotatable about a tilt axis. In some embodiments, the tray base member can be secured to the case so that the base axis is generally stationary with respect to the case. The base axis can intersect the tray shelf, the top surface of the case, and/or the bottom surface of the case. In some embodiments, a hole can be positioned in a generally central portion of the tray shelf.

Abstract: A case system and method includes a first case and a second case. The first case has wheels and an extendable handle having two handle shafts. The second case has two parallel grooves which receive the two handle shafts. The second case also has two latches which lock the two handle shafts in place within the two parallel grooves, so that the two case are secured together and may be wheeled about as a single unit. In a second embodiment of the invention, the first case has a top half and a bottom half, the top half being removable from the bottom half. When the bottom half is stacked on top of the top half, two cavities in the top half receive the two wheels of the bottom half so that the bottom half resides in a level orientation.

Abstract: A platform is selectively attachable to the wall of an open container. The platform includes a hanger which is placed over and engages the top rim of the container wall. A bracket is pivotal between a flat storage position and a locked position perpendicular to the planar body of the platform. When the bracket is placed in the locked perpendicular position, the hanger may be placed over the top rim of the upstanding wall so that the bracket abuts the outside surface of the upstanding wall and the platform is therefore maintained in a substantially horizontal orientation.
