Abstract

An improved swing away style door hinge utilizing three articulated hinge members and a means for controlling the position of at least one of the hinge members with respect to at least one other hinge member such that the hinge allows greater access through a doorway when the door is opened at a 90 degree angle.

8. The hinge of claim 7, wherein the fourth hinge member is positioned on a top end of the hinge.

9. The hinge of claim 7, wherein the fourth hinge member comprises a pair of fourth hinge members wherein a first fourth hinge member is positioned on a top end of the hinge and a second fourth hinge member is positioned on a bottom end of the hinge.

10. The hinge of claim 7, wherein the intermediate portion and second end of the first hinge member are generally formed at an obtuse angle with the generally planar first end of the first hinge member.

11. A hinge for attachment of a door to a jamb attachment face of a door jamb of a doorway, the doorway having a clearance space defined by the space between two parallel planes, each plane co-planar with a corresponding front face of a door stop on either side of the doorway, the hinge comprising:

a first hinge member fixably attached to the door jamb;

a second hinge member fixably attached to the door,

a third hinge member having a first end hingedly attached to the first hinge member and a second end hingedly attached to the second hinge member; and

at least one fourth hinge member positioned generally perpendicular to the first, second and third hinge members, having a first end pivotally attached to the second hinge member and a second end pivotally attached to the first hinge member;

wherein the door is positioned outside of the doorway clearance space when the door is opened 90 degrees and moveable to a position wherein the second hinge member is completely on the jamb side of the jamb attachment face.

12. The hinge of claim 11, wherein the first hinge member comprises a first generally planar end portion fixably attached to the door jamb, a second end portion including at least one knuckle, and an intermediate portion between the first end portion.

13. The hinge of claim 12, wherein the second end portion and the intermediate portion of the first hinge member are generally formed at an obtuse angle with the generally planar first end of the first hinge member.

14. The hinge of claim 11, wherein the first end of the fourth hinge member is attached to a pin extending from the second hinge member.

15. The hinge of claim 14, wherein the pin extending from the second hinge member is positioned on the second hinge member at point between the attachment of the second hinge member to the door and the hinged connection of the third hinge member to the second hinge member.

16. The hinge of claim 11, wherein the second end of the fourth hinge member is attached to a pin fixably attached to and extending from the knuckle of the second end of the first hinge member.

17. The hinge of claim 16, wherein the pin fixably attached to and extending from the knuckle of the second end of the first hinge member is attached to a doorway side of the knuckle at a position between the third hinge member and the intermediate portion of the first hinge when the hinge is positioned in a door closed configuration.

18. The hinge of claim 11, wherein the at least one fourth hinge member comprises a first fourth hinge member and a second fourth hinge member;

wherein the first fourth hinge member is attached on a top side of the first and second hinge members; and

wherein the second fourth hinge member is attached on a bottom side of the first and second hinge members.

19. The hinge of claim 18, wherein a first end of the first fourth hinge member is pivotally attached to a pin extending from the top side of the second hinge member and the first end of the second fourth hinge member is pivotally attached to a pin extending from the bottom side of the second hinge member.
