Hinge for furniture
Hinge for furniture, comprising at least one pair of leaves ( 6 - 7 ) mounted in a transverse housing in a supporting profile ( 1 ) by means of parallel independent rotation pins ( 14 ), which extend through the knuckles ( 9 ) of the leaves, said knuckles being equipped with teeth ( 18 ), parallel to the rotation pins ( 14 ), which mesh with one another.
1. A hinge for furniture comprising: at least a pair of leaves mounted on a supporting profile, each leaf including an anchoring plate for anchoring the leaf to a piece of furniture, an end knuckle for mounting thereof on the profile, and a connecting intermediate arm between the end knuckle and the anchoring plate; wherein the leaves are mounted in a transverse housing of the profile by respective parallel independent rotation pins, which extend through the knuckles and are mounted on the profile in a longitudinal direction; the knuckles of the leaves each have teeth parallel to the rotation pins, which mesh with one another; and the supporting profile bears internal elastic means, which drive both leaves towards a position, in which the anchoring plates form a certain angle with each other.
2. The hinge according to claim 1 , wherein the at least a pair of leaves comprises at least two pairs of leaves, which are mounted on respective housings of the profile, with the rotation pins of one pair of leaves and the other aligned along the profile.
3. The hinge according to claim 2 , wherein the housings in which the different pairs of leaves are mounted, are located in positions axially spaced from each other and from the ends of the profile.
4. The hinge according to claim 1 , wherein the supporting profile includes wings with respective longitudinal facing grooves, and the elastic means comprise a flat spring with opposed edges, the flat spring being mounted, through the opposed edges thereof, in the respective longitudinal facing grooves of the wings of the supporting profile, the flat spring of which has a central window that determines two elastically flexible tongues, which rest against the knuckle of the two leaves of each pair of leaves, coinciding with respective abutments of said knuckles.
5. The hinge according to claim 1 , wherein the piece of furniture is a door, such that the at least a pair of leaves are anchored to two doors of the furniture, and the certain angle is an angle corresponding to the closed position of the two doors.
6. A hinge for furniture comprising: at least a pair of leaves mounted on a supporting profile, each leaf including an anchoring plate for anchoring the leaf to a piece of furniture, an end knuckle for mounting thereof on the profile, and a connecting intermediate arm between the end knuckle and the anchoring plate; wherein the leaves are mounted in a transverse housing of the profile by respective parallel independent rotation pins, which extend through the knuckles and are mounted on the profile in a longitudinal direction, the knuckles of the leaves each have teeth parallel to the rotation pins, which mesh with one another, and the supporting profile has a C-section and is provided internally, from a core, with mortisings for mounting the rotation pins of the pairs of leaves.
7. The hinge according to claim 6 , wherein the supporting profile is provided internally, from a free edge of wings thereof, with projections or longitudinal ribs which determine along said wings, seats for an external ornamental plate and an internal, longitudinal and laminar spring that presses said external ornamental plate against the seats thereof.
8. A hinge for furniture comprising: at least a pair of leaves mounted on a supporting profile, each leaf including an anchoring plate for anchoring the leaf to a piece of furniture, an end knuckle for mounting thereof on the profile, and a connecting intermediate arm between the end knuckle and the anchoring plate; wherein the leaves are mounted in a transverse housing of the profile by respective parallel independent rotation pins, which extend through the knuckles and are mounted on the profile in a longitudinal direction, the knuckles of the leaves each have teeth parallel to the rotation pins, which mesh with one another, and each pair of leaves is mounted on an U-shaped intermediate support that is coupled into the transverse housing of the supporting profile and between wings of the U-shaped intermediate support are located the knuckles of the pair of leaves, such that the rotation pins extend through the wings of the U-shaped intermediate support and the knuckles.
