Abstract
A hinge apparatus includes first and second hinge parts and a hinge pin assembly interconnecting the hinge parts. Cams on the hinge pin assembly are operatively associated for rotation with the hinge parts. Engaging surfaces of the cams provide dwell points during movement of the hinge parts relative to each other.
Claims23
A hinge apparatus providing at least one intermediate dwell position, said hinge apparatus comprising:
- a first hinge part and a second hinge part having interrelating structures;
- and
- a hinge pin assembly interconnecting said interrelating structures permitting relative pivotal movement of said first and second hinge parts about an axis of rotation defined by said hinge pin assembly;
- said hinge pin assembly comprising:
- a pin;
- a first cam plate on said pin and associated with one of said first hinge part and said second hinge part for rotation therewith, said first cam plate having a first contoured surface;
- a second cam plate on said pin and associated with the other of said first hinge part and said second hinge part for rotation therewith, said second cam plate having a second contoured surface disposed against said first contoured surface;
- and
- biasing means urging said first and second contoured surfaces into cooperative engagement.
A vehicle hinge apparatus for controlling swinging movement of a vehicle door, while providing intermediate dwell points in said movement, said hinge apparatus comprising:
- a body hinge part including a first mounting plate and first and second side plates in spaced relation;
- a door hinge part including a second mounting plate and third and fourth side plates in spaced relation;
- and
- a hinge pin assembly interconnecting said first, second, third and fourth side plates, said hinge pin assembly including:
- a hinge pin;
- a first cam plate disposed on said pin, said first cam plate having a first contoured surface and being connected to one of said body hinge part and said door hinge part for rotation therewith;
- a second cam plate disposed on said pin, said second cam plate having a second contoured surface and being connected to the other of said body hinge part and said door hinge part for rotation therewith;
- and
- spring means urging said first and second contoured surfaces into operative engagement.
A vehicle hinge apparatus comprising:
- a first hinge part;
- a second hinge part;
- a hinge pin interconnecting said first and second hinge parts for relative rotational movement about said pin;
- and
- first and second cams disposed on said hinge pin and operatively associated with said first and second hinge parts respectively, said cam plates having operatively engaging surfaces configured for providing alternating rotational zones of increased and decreased resistance to relative rotation.
