Window hinge assemblies including a hinge pin support and methods of using the same are described herein. The hinge assemblies include a track assembly, a shoe slidably engaged in a track of the track assembly, a sash arm configured for attachment to a rotating sash, the sash arm being pivotally attached to the shoe, and a connecting arm. The track assembly includes a base extending along a track axis, a shoe track extending along the track axis, a hinge pin attached to the base of the track assembly, and a hinge pin support restraining an upper end of the hinge pin from movement relative to the base.

Hinge for the movement in opening and closing of a door with respect to a shoulder of a furniture item, said hinge including return closing mechanisms, a first fixed part attached to the shoulder, and a second movable part attached to the door, the fixed part and the movable part being articulated one to the other so as to be able to rotate around a pin, which constitutes the axis of rotation of the hinge, wherein the return closing mechanisms include at least one spring arranged around the pin exerting a force in the direction of the axis of the pin in the final phase of closing, tending to rotate coupling surfaces of the fixed part and movable part of the hinge.

An adjustable base for mounting hinges for items of furniture, which comprises a fixing element which can be associated with a component of an item of furniture, a supporting element which can be associated with at least one component of a hinge, guiding elements for slideably guiding the supporting element with respect to the fixing element along a longitudinal direction, and actuation elements for slideably actuating, along the longitudinal direction, the supporting element with respect to the fixing element; the fixing element comprises a pair of side walls and the supporting element comprises a pair of wings which are substantially parallel to the longitudinal direction and are arranged between the side walls on opposite sides of the longitudinal central plane, each wing being slideably associated with a respective side wall so as to define the guiding elements.
