A refrigerator according to the present embodiment comprises: a cabinet having storage spaces; a main door, which can rotate with respect to the cabinet and opens/closes the storage spaces; a sub door rotating with respect to the main door; and a hinge device, which is fixed to the front surface of the cabinet, supports the lower sides of the main door and the sub door and provides the center of rotation of the main door and the center of rotation of the sub door, wherein the center of rotation of the main door and the center of rotation of the sub door can be positioned on the sub door.

A counterbalance assembly for an appliance hinge has a base including first and second spaced-apart side walls and a transverse face wall. A channel is located between the first and second side walls. First and second notch portions are respectively located in the first and second side walls. A rotating cam is supported on the base and has a camshaft that extends between the side walls and that is adapted for rotation about an axis of rotation, a first end located in the first notch portion and a second end located in the second notch portion. A biasing spring has an inner end engaged with the base and an outer end spaced from the base. A spring rod includes an outer end operatively coupled to the spring and an inner end operatively coupled to the lever. The lever also pivotally connects to the lobe of the cam. A damper assembly is connected to the base and having a piston which is moved between a first position and a second position by the lever contacting the piston. The piston damps movement of the counterbalance assembly.

The present disclosure describes locking mechanisms comprising a locking component and a latching component. The locking component is within or otherwise connected to a first structure, such as a sliding door, and the latching component is within or connected to a second structure, such as a door jam. The latching component comprises a latch structure comprising features that can accept a portion of the locking component to lock the first structure to the second structure. In some embodiments, the latching component comprises a recess within the latching component. In some embodiments, the locking component comprises a rotating engagement structure configured to engage the latching component.

A rotary wing aircraft with a fuselage that is equipped with at least one rail, comprising at least one sliding element, in particular a sliding door or a sliding window, that is slidably supported by the at least one rail, wherein the at least one sliding element is at least slidable along the at least one rail by means of an opening sliding movement into an opening movement direction from a fully closed position into a fully opened position, wherein a dampening unit is provided that dampens the opening sliding movement of the at least one sliding element upon reaching of the fully opened position.

A fenestration automated operating system includes a fenestration frame, fenestration panel and one or both of a panel operating assembly or a panel latch assembly. The panel operating assembly is coupled with one or both of the fenestration frame or the fenestration panel. The panel operating assembly includes a panel actuator coupled with the panel actuator. A panel latch assembly is coupled with one or both of the fenestration frame or the fenestration panel. The panel latch assembly includes a latch and a latch actuator coupled with the latch. A fenestration controller is configured to operate each of the latch actuator and the panel actuator.

A hinge comprising: a first hinge member (110) comprising a cylinder barrel (117) having a longitudinal direction (118); a second hinge member (111) pivotably mounted on the first hinge member (110); and a dashpot interposed between said hinge members (110, 111) and configured for damping a closing movement of said closure member. The dashpot comprises a closed cylinder cavity formed within the cylinder barrel (117); a damper shaft (124) which extends into the cylinder cavity and is connected to the second hinge member (111); and a piston (147) within said cylinder cavity. The hinge members (110, 111) are made of a synthetic material and the damper shaft (124) is made of metal.

A dashpot comprising: a closed cylinder cavity and a damper shaft (24) which are rotatable with respect to one another; a piston (47) which is slideable between two extreme positions; and a motion converting mechanism to convert the relative rotation between the cylinder barrel (17) and the damper shaft (24) into a sliding motion of the piston (47). The motion converting mechanism comprises two co-operating screw threads, one (58) being provided on an outer wall of the piston (47) and the other one being provided on an inner wall of the cylinder barrel (17) or on an inner wall of a plastic tubular element fixed to the cylinder barrel. By providing the screw thread (58) on the outside of the piston (47), the diameter of the screw thread (58) is increased thereby increasing its lead and thus causing a higher volume of hydraulic fluid to be displaced during operation of the dashpot.
