Abstract:
There is provided a showcase which can expand a goods mounting area of a rack within a range of no interference with cooling in a display room. The showcase comprises a display room surrounded with a transparent wall supported by support pillars erected at four corners of a bottom frame, and a door, a rack hung in the display room to display goods, a cold air outlet formed on one side of the bottom frame, and a cold air inlet formed on the other side of the bottom frame. A space between the transparent wall of the other side of the display room and the rack is narrower than a space between the transparent wall of one side of the display room and the rack.
Abstract:
There is provided a simply-structured showcase which can lock a door without damaging an appearance. The showcase comprises a door pivotally supported on one side of an opening of a display room constituted in a main body to close the opening to be freely opened, main body side key metal fittings rotatably mounted to a surface of the door side of the main body on the other side of the opening, and door side key metal fittings rotatably mounted to a surface of the main body side on a non-pivotal support side of the door. The key metal fittings comprise through-holes for lock insertion, and are usually positioned in a space between the main body and the door. Portions in which the through-holes are positioned are protruded outward from the space in a rotated state, and the through-holes match each other in the state.
