A display case door assembly for a temperature-controlled storage device includes a vacuum panel, a hinge rail, and a lighting element. The vacuum panel includes a first vacuum pane, a second vacuum pane, and an evacuated gap between the first and second vacuum panes. The evacuated gap provides thermal insulation for the vacuum panel. The hinge rail is coupled to an edge of the vacuum panel and configured to rotate along with the vacuum panel between an open position and a closed position. The lighting element is coupled to at least one of the edge rail and the vacuum panel and configured to emit light toward an interior of the temperature-controlled storage device when the hinge rail and vacuum panel are in at least the closed position.

This application is directed to a cabinet configured with at least a right side wall and a left side wall, defining together a cabinet space, closeable by a at least one front door pivotally articulated at a front portion of the cabinet and displaceable between a closed position and at least a first open position. At the first open position each of the at least one door is coplanar with a respective side wall and at least one of the right side wall and the left side wall are configured with wall rail segments. One or more of the respective at least one front door is configured with door rail segments, such that the wall rail segments are coextensive with respective door rail segments, with a sliding gap extending between neighboring ends of a wall rail segment and a door rail segment, and defining together one or more sliding planes. The planes are configured for slidingly supporting a support unit mountable thereon.

A cabinet door having a first member with a first recess disposed along a top side of the center panel between a first stile and a second stile, a second recess disposed along a bottom side of the center panel between the first stile and the second stile, and a first veneer having a longitudinally extending grain pattern; a second member with a second veneer having a longitudinally extending grain pattern, and a first rabbet; and a third member with a third veneer having a longitudinally extending grain pattern; and a second rabbet; where the second member fits into the first recess, the third member fits into the second recess, and the longitudinally extending grain pattern of the second veneer is parallel to the longitudinally extending grain pattern of the third veneer and perpendicular to the longitudinally extending grain pattern of the first veneer.

Provided herein is a door opening and closing apparatus capable of reducing torque of a motor required for removing an adhesive force between a door and a housing. The door opening and closing apparatus includes a motor configured to output power for opening and closing a door, a power transmission apparatus configured to transmit the power of the motor to a hinge by rotation of a plurality of driving gears, and an auxiliary apparatus configured to generate an auxiliary force for moving the door at a closing position toward an opening position, where the auxiliary force is generated at the auxiliary apparatus by the power of the motor before the power of the motor is transmitted to the hinge through the power transmission apparatus.

Embodiments of this application provide a testing apparatus, configured to test a battery and including a test body and a first door body. The test body may include an accommodating cavity for accommodating the battery, and an opening. The opening may communicate with the accommodating cavity, and the first door body may be connected to the opening and capable of moving relative to the opening. The first door body may have a first state and a second state; in the first state, the first door body may block a part of the opening; and in the second state, the first door body may seal the opening.
