Abstract: A food service cart comprising a removable and adjustable hinge which accommodates for the normal inconsistences that are inherent with the rotational molding process. The hinge comprises a bore which is defined off-center relative to its longitudinal axis, allowing the bore to be selectively adjusted relative to a side panel and a door of the food service cart and provide a proper alignment there between. A plurality of facets disposed on the hinge ensure that it does not further rotate as the door is being rotated relative to the side panel. The food service cart also includes an expandable end table which forms a flush service with a side panel of the cart when in a collapsed or contracted configuration. A plurality of tray supports are disposed in the food service cart along with a flume defined therein which assists in the transfer of heat through the food service cart.

Abstract: A plate assembly for increasing the efficiency and safety of a rotational molding machine. The plate assembly includes a mold plate that is coupled to a mold and mold frame, and an arm plate that is coupled to a distal end of rotating arm portion of the rotational molding machine. The mold plate includes means for being rotated relative to the arm plate that the mold plate may be selectively engaged to the arm plate. The mold plate and by extension the mold are locked into position via a plurality of coupling means disposed on the arm plate. Once secured, the rotational molding process is carried out by the rotational molding machine rotating the mold and plate assembly around at least one axis of rotation as the mold is indexed or rotated through each of the plurality of fabrication steps.

Abstract: A food service system is formed using a plurality of units capable of being interlocked together in a variety of customizable configurations. The units of the food service system include a food service bar with buffet pan chillers, a work table, a cashier station, and variety of connecting pieces for linking each of the units together. The food service bar comprises a sneeze guard that protects the food contained within the bar on three sides and can be broken down and folded down and into itself when the bar is being transported or stored. The buffet pan chillers are double sided and configured such that when frozen, may accommodate a shallow food pan on one side and then flipped over to accommodate a deep food pan on the other side while still maintaining the same serving height. Each unit is configured to receive multiple sizes of wheels or casters.

Abstract: A mobile serving cart with adjustable hinges that allows for the production inconsistencies associated with rotational molding. The cart comprises a plurality of door assemblies, each door assembly comprising at least two hinge assemblies, at least one hinge assembly being disposed at the upper portion of the door assembly, and at least one other hinge assembly being disposed at the lower portion of the door assembly. Each hinge assembly comprises at least two door bolts, at least one cart bolt, and a pivot rod. The cart rod is disposed between the at least two door bolts at an orientation that is orthogonal to the at least two door bolts. The hinge assemblies provide a means for the rotationally molded door assemblies and side walls of the cart to be tightly or snuggly coupled together despite the manufacturing inconsistencies inherent to the rotational molding process.

Abstract: An improved refrigeration and heating system comprising a thermochemical device, and a mobile service cart. The thermochemical device is capable of refrigerating or cooling the ambient air due to an internal chemical process. This same chemical process also produces a significant amount of heat as a by-product which, if left alone, would normally be vented or released in to the atmosphere and become lost. However because the theremochemical device is disposed at the center of the cart, the heat which is generated by the cooling process is retained and utilized to provide a separate heating area within the cart. This allows the current system to operate as a closed loop, meaning that the cart and thermochemical device work in conjunction to form a self-sustaining hot and cold storage area with very little maintenance or input from a user.
