The present disclosure provides a system for sealing a compartment. The system includes a door with a seal positioned on a bottom surface of the door. The system also includes one or more hinges coupled to the door. The door rotates from a closed position to an open position via the one or more hinges. A height of the door with respect to a floor surface increases in response to a rotation of the door from the closed position to the open position due to a helical slope of both a first cam surface of the one or more hinges and a second cam surface of the one or more hinges. The seal transitions from a compressed state to a relaxed state in response to the rotation of the door from the closed position to the open position.

A hinge device 1 comprises a dumper hinge 2 and a gravity hinge 3. The gravity hinge 3 comprises a rotational force imparting mechanism 70 for converting gravity of the door 6 to rotational force to a closing direction when the door 6 rotates to the closing direction. The dumper hinge 2 comprises a dumper mechanism 30 for reducing the rotational force to the closing direction of the door 6. The dumper mechanism 30 includes a linear dumper 31 disposed to the first hinge member 10 and a first cam member 32 and includes a second cam member 35 disposed to the second hinge member 20. The linear dumper 31 is positioned far from the shaft member 40 in an orthogonal direction to a shaft line of the shaft member 40 and is positioned along the shaft member 40. When the door 6 rotates, the linear dumper 31 is shortened.

A gate unit includes a gate mount adapted to mate with a frame bordering a passageway. The gate mount includes a gate hinge including a stationary pivot support and a movable pivot that is mated in rotative bearing engagement with the stationary pivot support to establish a gate-pivot axis. A gate is coupled to the movable pivot of the gate hinge for pivotable movement with the movable pivot about the gate-pivot axis between a closed position closing a walkway passage formed in the gate mount to block movement of a person through the walkway passage and an opened position opening the walkway passage to allow movement of a person through the walkway passage.

A gate unit includes a gate mount that is adapted to mate with a frame bordering a passageway and formed to include a latch receiver and a gate mounted on the gate mount for pivotable movement about a gate-pivot axis between an opened position opening a walkway passage formed in the gate mount and a closed position closing the walkway passage formed in the gate mount. The gate unit further includes a gate lock configured to lock the gate in the closed position closing the walkway passage formed in the gate mount.

A gate is mounted on a hinge to pivot about a pivot axis between opened and closed positions. A latch is mounted for movement relative to the gate to retain the gate in a closed and locked position

A display case door assembly for a temperature-controlled storage device includes an opening into the temperature-controlled storage device and a vacuum panel mounted within the opening. The vacuum panel includes a first vacuum pane of tempered glass, a second vacuum pane of tempered glass, and an evacuated gap between the first and second vacuum panes. The evacuated gap has a predetermined thickness within which a vacuum is drawn, thereby providing a thermal insulation effect for the vacuum panel. The vacuum panel further includes a plurality of spacers disposed within the evacuated gap and configured to maintain the predetermined thickness of the evacuated gap when the vacuum is drawn therein.

The transparent unit further includes a plurality of spacers disposed within the evacuated gap and configured to maintain the predetermined thickness of the evacuated gap when the vacuum is drawn therein.

A shower door hinge assembly includes a clamp, a member, a base, a spacer, and a pin. The clamp is configured to receive a portion of a shower door. The member is coupled to the clamp, and comprises a circumferential slot. The base is configured to be coupled to a fixed structure, and defines a hole. The spacer is coupled to the base. The member is rotatably coupled to the spacer. The pin includes a first end and a second end. The first end is configured to be received in the hole of the base, and the second end is configured to be received in the circumferential slot. The pin and the circumferential slot are cooperatively configured to define an end point of rotation for the shower door.
