Abstract
A door hinge having a particularly reliable and solid stop and holding device. The movable part (13) of the hinge lies along the hinge pin (1) between the fixed part (14) and a housing (17) which contains the holding mechanism and is integral with the fixed part (14). In the housing, a pivotable lever (19) is rotationally fastened to the movable part (13) and supports a roller (26) against which one or more notches (42, 45) are pushed by a spring-loaded device (31, 40). The notches define the open positions of the door (11). The housing (17) is sealed and fits onto the fixed part and the hinge pin. The hinge can be used particularly in motor vehicle doors.
Claims15
A hinge for a door having at least one stop notch, said hinge comprising:
- a fixed part attachable to a door frame;
- a movable part being secured to a door (11) and rotatably articulated to said fixed part via a hinge pin (15) to allow said movable part to pivot with said door about said hinge pin,
- a notch mechanism (16) interacting with said fixed and movable parts and having at least one stop notch for maintaining said door in at least a partially open position,
- a housing (17) containing said mechanism (16) and being fastened to one of said fixed and movable parts (13, 14), and
- a lever (19) being located within said housing (17) and being fastened to the other of said fixed and movable parts (13, 14), said lever (19) having an axial bore (19a) engaging said pin (15), and a first end of said lever (19) being engagable with said mechanism,
- wherein a pivotable part (31) is located in said housing and has a rotational axis (32) which extends parallel to a longitudinal axis of said hinge pin (15), said mechanism comprises at least first and second notches (29, 30) formed by concave surfaces which are supported by said pivotable part (31), and a biasing mechanism (33) biases said pivotable part (31) to a central pivot position so that said pivoting part initially pivots in a first direction as said lever (19) engages said first notch (29) and pivots in a second opposite direction initially as said lever (19) engages said second notch (30).
A hinge for a door having at least one stop notch, said hinge comprising:
- a fixed part attachable to a door frame;
- a movable part being secured to a door (11) and rotatably articulated to said fixed part via a hinge pin (15) to allow said movable part to pivot with said door about said hinge pin,
- a notch mechanism (16) interacting with said fixed and movable parts and having at least one stop notch for maintaining said door in at least a partially open position,
- a housing (17) containing said mechanism (16) and being fastened to one of said fixed and movable parts (13, 14), and
- a first lever (19) being located within said housing (17) and being fastened to the other of said fixed and movable parts (13, 14), said first lever (19) having an axial bore (19a) engaging said pin (15), and a first end of said first lever (19) being engagable with said mechanism,
- wherein said mechanism comprises a cam lever (38) which has a cam surface (38a, 43) provided with first and second notches (42, 45), a first end of said first lever (19) is pivotable supported by said housing, and a biasing mechanism biases a second opposed end of said cam lever (38) toward said first lever (19) for engagement with the first lever (19) as the door is moved to an opened position.
