- d) an upper bracket having mounting means to mount the upper bracket on the door;
- e) an interior pivot pin, parallel to said exterior pivot pin, extending between the upper bracket and the central pivot link providing for rotational movement of the door with respect to the central pivot link around the interior pivot point;
- f) exterior pivot detent means for providing at least one detent position located where the central pivot link is rotated to a fully extended position relative to the lower bracket;
- g) interior pivot detent means for providing at least one detent position for the upper bracket with respect to the central pivot link;
- h) biasing means for applying torque from the lower bracket to the central pivot link in the opening direction of the door; and
- i) biasing means for urging the central pivot link against the lower bracket whereby increased longitudinal load is placed on the central pivot link against the lower bracket.
- 10. The hinge of claim 9, including at least one rotation stop point that limits rotational movement of the central pivot link with respect to the lower bracket.
- 11. The hinge of claim 9, wherein the interior pivot detent means including a cammed surface, the cammed surface having a plurality of cam lobes located integral to the upper bracket adjacent and radially around the interior pivot pin and also including a mating cammed surface, having a like plurality of cam lobes located integral to the central pivot link and radially around the interior pivot pin.
- 12. The hinge of claim 9, including camming means to compel the exterior pivot point to fully rotate for the entire travel of the exterior pivot point prior to the interior pivot permitting motion when the door is opened and that compels the interior pivot point to fully rotate for the entire travel of the interior pivot point prior to the exterior pivot point permitting motion when the door is closed.
- 13. The hinge of claim 9, wherein the biasing means for urging the central pivot link against the lower bracket and the biasing means for applying torque are a single coil spring having a first and a second spring end, said first spring end secured within said central pivot link and said second end secured within said lower bracket whereby, when said central pivot link is rotated with respect to said lower bracket, said spring applies torque.
- 14. The hinge of claim 13, including camming means to compel the exterior pivot point to fully rotate for the entire travel of the exterior pivot point prior to the interior pivot permitting motion when the door is opened and that compels the interior pivot point to fully rotate for the entire travel of the interior pivot point prior to the exterior pivot point permitting motion when the door is closed.
- 15. A hinge having an interior pivot point and an exterior pivot point for mounting a door to a frame, the door capable of moving in an opening direction and a closing direction, said hinge comprising:
- a) a lower bracket having mounting means to mount the lower bracket on the frame;
- b) a central pivot link rotationally attached to the lower bracket;
- c) an exterior pivot pin extending between the lower bracket and the central pivot link providing for rotational movement of the pivot link with respect to the lower bracket around the exterior pivot point;
- d) an upper bracket having mounting means to mount the upper bracket on the door;
- e) an interior pivot pin, parallel to said exterior pivot pin, extending between the upper bracket and the central pivot link providing for rotational movement of the door with respect to the central pivot link around the interior pivot point;
- f) exterior pivot detent means for providing at least one detent position located where the central pivot link is rotated to a fully extended position relative to the lower bracket;
- g) interior pivot detent means for providing at least one detent position for the upper bracket with respect to the central pivot link;
