Patent ID: 7905524

Claim:
A door with a pressure opening assembly positioned on a piece of furniture, comprising: a pull-push closing device attached to an interior side of the piece of furniture, the pull-push closing device comprising a first coupling element configured to engage a second coupling element located at an interior side of the door, and a first spring member; at least one articulated hinge positioned between the interior side of the door and the interior side of the piece of furniture, for allowing pivoting motion of the door, the at least one articulated hinge having a quadrilateral shape and movable between a compressed and a decompressed state, the at least one articulated hinge comprising: a wing fastened to the interior side of the piece of furniture and a bowl fastened to the interior side of the door; an outer and inner connecting rods, each pivotally connected to the wing and to the bowl; a second spring member positioned between the wing and the inner connecting rod, having a first arm bearing against the wing and a second arm bearing against a protrusion on one end of the inner connecting rod; wherein, when the door is closed, the first spring member is compressed by the first coupling element when the door is closed relative to the piece of furniture and the second spring member will be also compressed between the wing and the inner connecting rod so as to position the at least one articulated hinge in a compression state inside the bowl; and wherein, when a pushing force is exerted to the exterior side of the door, the first spring member will be decompressed to bias and move the first coupling element out of engagement with the second coupling element and the second arm of the second spring member will thrust against the protrusion of the inner connecting rod for pushing the hinge from the compressed state toward an open state, so that the at least one articulated hinge aid in the opening of the door by pushing the door toward the open position.
