Patent ID: 7871113

Claim:
A door unit for a cold storage including a main body having an outer front surface and two outer side surfaces orthogonal thereto, whose front surface opening is closed in an openable and closable manner by means of a door having an outer front face and two outer side faces orthogonal thereto, whose one outer side is pivotally supported on the main body, the door unit including: a handle pivotally mounted on one outer side face of the door on its non-pivotal side at a location of a predetermined height so as to pivot about an axis extending horizontally between the two outer side faces of the door; a latch receiver provided on the forward portion of one outer side surface of the main body at a height corresponding to the height of the handle, the latch receiver having a roller pivotally mounted thereon; and the handle integrally comprising an elongated grip adapted to be grasped by fingers of a hand along its length and a latch detachably engageable with the latch receiver so that the latch engages the latch receiver in a state that a length direction of the grip is substantially vertical when the door is in a fully closed position by action of the latch and extends along the one outer side face of the door, and when the grip is pivotally moved in a direction away from the front surface of the main body, to reach a position where the length direction of the grip is relative to a horizontal plane at a predetermined angle, then both the pivotal movement of the handle is stopped by a pivoting limiting means and the latch disengages from the latch receiver; wherein the latch is protruding portions from a rear surface of the handle that extend rearwardly toward the main body and then extend downwardly for engaging the roller, when the grip is substantially vertical, and includes a roller receiver at a corner formed by the portions extending rearwardly then extending downwardly, and when the grip is pivotally moved in a direction rearward to a substantially vertical position, the latch engages the latch receiver from upward, the roller is received in the roller receiver, and the latch engages the latch receiver completely.
