REFRIGERATION UNITS AND DOOR SYSTEMS FOR REFRIGERATION UNITS

摘要

Refrigeration units and door systems for refrigeration units are provided. A door system for a refrigeration unit includes an outer frame and at least two sliding doors having the same size. Each door can include inner, outer, upper and lower sides that can have side outer surfaces presenting a seal profile that permits each door to seal when in a closed position. Each door can include pins extending outward from side outer surfaces of the upper and lower sides. The door system can include two parallel running rails within the outer frame. Each rail can include an upper sliding groove in which the pins of the sliding door run when the sliding doors move to an open position and a plurality of seating grooves that open up to the upper sliding grooves and extend downward from the upper sliding grooves in which the sliding doors reside in a closed position.

1. A door system for a refrigeration unit comprising:
an outer frame; at least two sliding doors having the same size, each door comprising:
a frame with an inner side, an outer side, an upper side and a lower side and one or more slider guides on a top surface of the inner side, the slider guides serving as support for the other sliding door when the other sliding door is in an open position;the inner side, outer side, upper side and lower side having side outer surfaces that present a profile that permits each door to seal tightly when in a closed position;pins extending outward from a side outer surface of the upper side and a side outer surface of the lower side of the frame; two parallel running rails within the outer frame, the rails aligning with the upper and lower sides of the sliding doors, each rail comprising an upper sliding groove in which the pins of the sliding door run when the sliding doors are being moved to an open position and a plurality of seating grooves that open up to the upper sliding grooves and extend downward from the upper sliding grooves the pins residing in the seating grooves when the sliding doors are in a closed position; and the sliding doors residing in the same plane when the sliding doors are in a closed position and the sliding doors residing in two parallel planes when one of the sliding doors is in an open position.
