A concealed hinge for the rotatable movement of a door fixed to a door frame. The hinge includes: a fixed hinge body anchorable to the frame; a movable hinge body anchorable to the door; a connecting assembly for mutual connection of the fixed hinge body and movable hinge body so that the latter rotates with respect to the former about a first longitudinal axis between an open position and closed position. The fixed (or movable) hinge body includes a first (or second) box-shaped element concealedly insertable within the door (or frame). The first (or second) box-shaped element defines a second axis parallel to the first axis. The connecting assembly protrudes from the first box-shaped element in the open position of the movable element, the first box-shaped element being susceptible to internally contain the connecting assembly in the closed position of the movable element.

A retail display unit includes a top, a base including a slot and at least one swing door. The at least one swing door is rotatably coupled to the top and the base and includes a main panel and a lower rail engaged with a bottom of the main panel. A door catch is mounted to a back side of the lower rail and has a channel opening that faces downwardly at the base. A latch is rotatable through the slot in the base. When the at least one swing door is in a closed position, the latch is rotated through the slot in the base and positioned in the channel opening of the door catch to lock the at least one swing door.

A hinge assembly for a door of a household appliance has a first hinge and a second hinge. The first hinge includes a base portion and a door receiving portion. The base portion includes at least one elongated slot to receive a fastener. The elongated slot enables positioning of the door receiving portion. The second hinge includes a mounting block and a door plate. The door plate has a door receiving portion that has at least one elongated slot to enable positioning of the door receiving portion. The door plate is secured via at least one fastener to the mounting block. The mounting block is movable in a direction substantially perpendicular to the door plate for positioning the door.

A hinge assembly for securing a door on a gaming machine cabinet includes a first flange coupled to the door, a second flange coupled to the cabinet, a first link pair coupled to and extending from the first flange at a first pivot joint, a second link pair coupled to and extending from the first flange at a second pivot joint, a third link pair coupled to the first link pair at a third pivot joint, wherein the third link pair is further coupled to the second flange at a fourth pivot joint, and wherein the third link pair is further coupled to the second link pair at a fifth pivot joint, and a fourth link pair coupled to the second flange at a sixth pivot joint, wherein the fourth link pair is further coupled to the second link pair at a seventh pivot joint.

A hinge includes a bearing plate, a linkage mechanism, a shell element, and an elastic element. The linkage mechanism is linked to the bearing plate. The shell element is disposed on the support, is connected to the linkage mechanism and includes a receiving space. The elastic element is disposed in the receiving space and abuts against between the linkage mechanism and the shell element to provide an elastic force. When an external force is applied, the display device and the bearing plate rotate relative to the support between a first position and a second position. The bearing plate is linked to the linkage mechanism to compress or loosen the elastic element, and then the elastic force is changed. When the external force is removed, the display device and the bearing plate can be stopped at once at any position between the first position and the second position.

The present invention provides a refrigerator, comprising a cabinet, a door and a hinge body, wherein a positioning shaft and a guiding shaft are provided on the hinge body, and a positioning groove and a guiding groove are provided on the door; the door of the refrigerator according to the present invention may be moved by a distance in a direction away from a pivoting side when being opened, thereby avoiding inconvenience of opening the door due to the protrusion of the side wall of the door.
