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.

Door unit for cold storage

A low-temperature storage cooled/maintained in an ultra low temperature range, in which door lowering is automatically modified by an opening/closing operation of a thermal insulating door, and a concave/convex portion which is a contact portion with respect to a door switch disposed on the door can be secured. The low-temperature storage includes a thermal insulation box main body having an opening in a front surface thereof; a thermal insulating door openably/closably attached to the thermal insulation box main body by a plurality of hinges to close the opening; and a cooling device which cools a storage chamber formed by the door and the main body, wherein a spacer having a guide surface to forcibly correct door lowering by a closing operation of the thermal insulating door is disposed on a side on which any hinge is not disposed.

Low-temperature storage

An object is to provide a low-temperature storage capable of further dividing a medium storage chamber divided by a medium partition into upper/lower small sections (small storage chambers) by adding of an optional component and changing of an inner door, and the storage comprising; a thermal insulation box main body having an opening in a front surface thereof; a thermal insulating door openably/closably attached to the thermal insulation box main body; a medium partition which divides the opening into upper/lower medium openings; a shelf which divides a storage chamber formed by the thermal insulating door and the main body into upper/lower chambers in a position of the medium partition; a cooling device which cools the storage chamber; a metallic optional partition member which further divides the medium openings into upper/lower openings; a frame member formed of a resin and attached to a front part of the partition member to support an optional gasket; and a plurality of inner doors which openably close small openings divided by the partition member.

There is disclosed a cold storage which improves a door insulating performance, and which is preferable particularly for low-temperature insulation of chemicals, and the like. A low-temperature insulating showcase is formed by openably closing a storage chamber opening constituted in an insulation box by a door, the door is constituted of a transparent panel and a see-through composite layer glass, and a panel is detachably attached to the storage chamber side of the composite layer glass.
