Patent attributes
The invention has an object to provide a door unit for a cold storage, enabling easy opening and closing operations of a door by engaging a latch with a latch receiver. The door unit includes a handle pivotally mounted on the side face of an outer door on its non-pivotal side at a predetermined height, and a latch receiver provided on the forward portion of a side surface of a main body at a height corresponding to the handle. The handle includes a grip to be grasped by fingers of a hand, and a latch detachably engageable with the latch receiver so that the latch engages a roller of the latch receiver in a state of the substantially vertical grip, and when the grip is pivotally moved in a direction away from the main body to a position where the grip intersects a horizontal plane at a predetermined angle, the pivotal movement of the handle is stopped and the latch disengages from the roller of the latch receiver.
