Abstract

The invention features a hinge or coupling two panels (P1, P2), one of which at least opens rotatably about an axis (X) parallel to the planes of the said panels, comprising a mobile fixing element (1) on the opening panel, a fixing element on the other panel and linking means (3) between the fixing elements co-operating with elastic return means of the panel opening to at least a stable angular equilibrium position, characterized in that the said return means consists of a ring (4) located in a cavity (10) of the mobile fixing element (1) and capable of being elastically deformed by the pressing action of a cam (30) rotating about a central shaft (5) parallel to the planes of the panels, being carried by the linking means (3).

Claims

1. A hinge for use in coupling first and second panels of which at least said first panel is movable by rotation about an axis parallel to respective planar surfaces of said first and second panels, comprising:

a first fixing element adapted to engage the first panel, said first fixing element comprising a removable ring disposed in a cavity thereof and a central shaft disposed parallel to the planar surfaces;

a second fixing element adapted to engage the second panel and having a link extending therefrom, said link further having a cam defined by a prismatic end thereof having plural surfaces, said link being rotatable about said central shaft with said cam thereby disposed in movable contact with a face of said ring;

wherein, plural angular equilibrium positions of said first and second fixing elements are defined by contact between said face of said ring and corresponding surfaces of said cam, and relative movement of said first and second fixing elements between said plural equilibrium positions is encouraged by elastic deformation of said ring by pressing action of at least one intersection of said surfaces of said cam against said ring.

2. The hinge according to claim 1, wherein said plural surfaces further comprise three lateral surfaces of said cam respectively connected at approximately 90°

angles by curvilinear edges.

3. The hinge according to claim 1, wherein said ring further comprises lateral ears adapted to preclude lateral movement of said ring.

4. The hinge according to claim 1, wherein said first fixing element further comprises two recessed cylinders adapted to receive respective ends of said central shaft, said cam being retained in contact with said ring between two recessed cylinders.

5. The hinge according to claim 1, wherein said first fixing element further comprises a stirrup element and a substantially parallel flange adapted to enclose said ring and said cam therebetween, and thereby permit engagement with a periphery of a notch provided on an edge of said first panel.

6. The hinge according to claim 5, wherein a central space defined between said stirrup and said flange is occupied by a shim surrounding said cavity for housing the ring.

7. The hinge according to claim 6, wherein said stirrup is coupled to said flange by a screw projecting through the cavity at a center of said ring.

8. The hinge according to claim 1, wherein said cam comprises an inner conduit traversed by said central shaft, thereby providing a degree of freedom in rotation of said cam.

9. The hinge according to claim 1, wherein said link is fixedly coupled to said second fixing element.

10. The hinge according to claim 9, wherein said link is fixedly coupled to said second fixing element via a 90°

bend.

11. The hinge according to claim 1, wherein said link further comprises a second cam at a second end thereof, said second fixing element further comprising a second removable ring in movable contact with said second cam.

12. The hinge according to claim 11, wherein the link is rectilinear to allow a 360°

clearance of the first and second panels.

13. The hinge according to claim 12, wherein the link further comprises a profile so as to define between respective ends thereof an angle between approximately 90°

and 180°

.

14. The hinge according to claim 1, wherein said second fixing element further comprises a plate adapted for fixing said second fixing end to a wall.
