## Abstract

A hinge for door leaves of furniture and the like, which comprises a fixed part that can be connected to a body of a piece of furniture and a movable part that can be connected to a door leaf of the piece of furniture, the fixed part and the movable part being mutually connected in an oscillating manner by way of an articulation system that comprises at least one articulation axis and a rocker, the hinge comprising elastic means for opening the hinge which are functionally connected to the at least one rocker; the fixed part of the hinge is shaped so that it can be inserted into a seat defined within the thickness of an upper or lower wall of a piece of furniture.

## Claims

### Claim 1

A hinge for door leaves of furniture, which comprises a fixed part that can be connected to a body of a piece of furniture and a movable part that can be connected to a door leaf of the piece of furniture, the fixed part and the movable part being mutually connected in an oscillating manner by way of an articulation system that comprises at least one articulation axis and a rocker, the hinge comprising elastic means configured to open the hinge, which are functionally connected to said at least one rocker, wherein said fixed part of the hinge is shaped so that it can be inserted into a seat defined within the thickness of an upper or lower wall of the piece of furniture, said fixed part and said at least one rocker extending along a plane that is perpendicular to said at least one articulation axis, and
further comprising a movable transmission element for transmission between said elastic opening means and said at least one rocker, said movable transmission element extending and being movable along said perpendicular plane and having a thrust surface that is shaped and arranged in order to act against a lateral contact surface of said rocker.

### Claim 2 (depends on 1)

The hinge according to claim 1, wherein said thrust surface of the movable transmission element acts on said contact surface of the rocker at least in a neighborhood of the closed position of the hinge.

### Claim 3 (depends on 1)

The hinge according to claim 1, wherein said thrust surface of the movable transmission element and said contact surface of the rocker extend parallel to said at least one articulation axis.

### Claim 4 (depends on 1)

The hinge according to claim 1, wherein said movable transmission element is constituted by a lever that is supported in an oscillating manner by said fixed part of the hinge.

### Claim 5 (depends on 4)

The hinge according to claim 4, wherein said lever is supported in an oscillating manner by way of an oscillation axis that is arranged in an intermediate position along said lever, said elastic means acting on a first end of the lever, said thrust surface being provided at an end that is opposite with respect to said first end.

### Claim 6 (depends on 1)

The hinge according to claim 1, wherein said movable transmission element is constituted by a roller that is supported so that it can rotate by a sliding element pressed by said elastic means.

### Claim 7 (depends on 1)

The hinge according to claim 1, wherein said thrust surface of the movable transmission element and/or said lateral contact surface of said rocker is cam-shaped.

### Claim 8 (depends on 1)

The hinge according to claim 1, wherein said elastic means comprise a helical spring.

### Claim 9 (depends on 1)

The hinge according to claim 1, wherein the articulation system between the fixed part and the movable part of the hinge comprises four articulation axes and two rockers, which extend along said plane at right angles to the articulation axes.

### Claim 10 (depends on 1)

The hinge according to claim 1, further comprising adjustment means for adjusting the relative position between said fixed part and said movable part of the hinge in at least one among the lateral, front and vertical directions.

### Claim 11 (depends on 10)

The hinge according to claim 10, wherein said seat for the fixed part of the hinge opens onto a front side of the body of the piece of furniture, said adjustment means of the hinge being provided with actuation means that can be accessed from the front side of the body of the piece of furniture, said actuation means being arranged at the front side of the piece of furniture where said seat for the fixed part of the hinge opens.
