Abstract
A hinge includes a first rigid element enclosing elastic elements that have at least one elastic end oriented so that the elastic elements extend into a plane perpendicular to the axis of rotation of the hinge. One end of the first rigid element is formed by a knuckle-piece, which is inserted between a pair of knuckles that together constitute the rigid second element. A pin passes through all the knuckles. A bush, disposed between a female hinge of the second rigid element and the pin, defines a peripheral surface which serves as a cam surface, against which at least one portion of the elastic elements is adjusted.
Claims20
A hinge comprising:
- a first rigid part including a first knuckle at one end;
- a second rigid part comprising a second and a third knuckle at a first end, said first knuckle being insertable between said second and third knuckles, said first rigid part being pivotably mounted about a pin that extends through said first, second and third knuckles;
- a leaf spring contained within said first rigid part, said leaf spring comprising a clamping portion for engaging a cam surface for defining stable relative angular positions of said first and second rigid parts;
- and
- a bush around said pin, said bush having a cylindrical passage accommodating said pin and an external peripheral surface forming said cam surface;
- said leaf spring expanding perpendicular to axes of rotation of said first and second rigid parts;
- said leaf spring being substantially in a shape of a Y having two arms that form said clamping portion.
A hinge comprising:
- a first rigid part including a first knuckle at one end;
- a second rigid part comprising a second and a third knuckle at a first end, said first knuckle being insertable between said second and third knuckles, said first rigid part being pivotably mounted about a pin that extends through said first, second and third knuckles;
- a leaf spring contained within said first rigid part, said leaf spring comprising a clamping portion for engaging a cam surface for defining stable relative angular positions of said first and second rigid parts;
- and
- a bush around said pin, said bush having a cylindrical passage accommodating said pin and an external peripheral surface forming said cam surface;
- said leaf spring expanding perpendicular to axes of rotation of said first and second rigid parts;
- said clamping portion is substantially in a shape of a Y having two arms and wherein said leaf spring further comprises a third arm made in one piece with said two arms adjacent to said two arms, said third arm elastically abutting against said second rigid part.
A hinge comprising:
- a first rigid part including a first knuckle at one end;
- a second rigid part comprising a second and a third knuckle at a first end, said first knuckle being insertable between said second and third knuckles, said first rigid part being pivotably mounted about a pin that extends through said first, second and third knuckles;
- a leaf spring contained within said first rigid part, said leaf spring comprising a clamping portion for engaging a cam surface for defining stable relative angular positions of said first and second rigid parts;
- and
- a bush around said pin, said bush having a cylindrical passage accommodating said pin and an external peripheral surface forming said cam surface;
- said leaf spring expanding perpendicular to axes of rotation of said first and second rigid parts;
- said leaf spring is several superimposed leaf springs.
