Abstract: A backpack frame has a front frame member in a front plane and a rear frame member in a rear plane that is spaced rearwardly of the front frame member. At least one spacer is connected between the frame members to hold the rear frame member in spaced relationship behind the front frame member. The rear frame member defines a load stand-off element at the rear plane to contact the load and to hold the load away from the body and legs of the user while the user is walking. One or more shoulder-engaging members such as a pair of straps is positioned for placement on the shoulders of the user and a flexible back-engaging panel member is connected in position to rest against the user's back below the shoulders to place a user's back at or forward of the front plane. A load-carrying support member on the backpack frame extends at least as far rearwardly as the rear plane to carry the load.

Abstract: An air distribution bi-folding door assembly of a refrigerated case opens and closes to allow for the loading of refrigerated items in the case. The doors are attached by a hinge. Each door is hollow and includes perforations which allow cool air which flows in the hollow space of the doors to distribute over the refrigerated items in the case. A wheel assembly is attached to the upper outer corner of each door and runs along a track as the doors open and close. An alignment assembly attached to the lower outer corners of each door ensures proper alignment of the doors during opening and closing.
