An automated gate for robotic mowers may include at least two doors that are sized to receive a robotic mower, and it can be installed in any fence to enable the mower to move between the yards on its own. The at least two doors of an automated gate may provide optional capability to lock when not used by the mower and unlock automatically when the mower gets close. By default, the at least two doors may remain unlocked, yet closed, thereby providing a cost-effective solution for customers who do not have to worry about pets. An add-on module may be provided that may add a locking mechanism and triggering mechanism, thereby providing end users with the ability to lock the automated gate completely.

The present disclosure provides a hinge, a freight container that includes the hinge and a freight container that includes a locking rod and optionally the hinge. The hinge includes a locking pin, a first wing, a second wing and a first hinge pin that pivotally connects the first wing to the second wing. The hinge further includes a pair of hinge lugs each having a first set of surfaces defining openings through which a second hinge pin passes and at least one of the pair of hinge lugs having a surface defining an opening through which a locking pin reversibly travels.

Disclosed herein is a refrigerator of which door is opened without interference by a structure positioned next to a side of the refrigerator. Since a main body and the door of the refrigerator are provided with hinge units, while the door is opening, the hinge units rotate in a direction in which the door rotates while protruding, and thus the structure positioned next to the side of the refrigerator is not positioned in a radius of rotation of the door, and the door may rotate without interference. In addition, hinge covers which move in conjunction with the movement of the hinge units are provided at one sides of the hinge units. When the hinge units protrude due to the opening of the door, since protrusions of the hinge units are provided not to be exposed by one ends of the hinge covers sliding.
