Door hinge and galley enclosure including the same
View Patent ↗A 180 degree opening door hinge including an elongate spine having first and second edges extending along a length thereof, a primary hinge pivotally-mounted adjacent the first edge having a bracket for attaching the spine to a door jamb, and a secondary hinge pivotally-mounted adjacent the second edge having a bracket for attaching the spine to a door, wherein each of the primary and secondary door hinges have a range of pivoting motion of about 90 degrees relative to the spine, and a combined range of pivoting motion of about 180 degrees of the door relative to the door jamb.
1. A 180 degree opening door hinge, comprising:
(a) an elongate spine having a thickness, width and first and second longitudinally-extending edges extending along a length thereof, the spine having a first bore and a second bore extending along the respective first and second edges, and having at least one access port communicating with the first edge and the first bore and at least one access port communicating with the second edge and the second bore;
(b) a primary hinge pivotally-mounted adjacent the first longitudinally-extending edge of the spine and having a primary mounting bracket for attaching the spine to a door jamb, the primary hinge including a first hinge spindle positioned in the first bore and mounted in a first hinge spindle bushing extending through the at least one access port communicating with the first edge and carried on the primary mounting bracket for receiving the first hinge spindle therein for pivoting movement therein;
(c) a secondary hinge pivotally-mounted in spaced-apart relation to the primary hinge and adjacent the second longitudinally-extending edge of the spine for movement independent of the primary hinge, and having a secondary mounting bracket for attaching the spine to a door adapted for being opened and closed by pivotal movement of the door in relation to the door jamb, the secondary hinge including a second hinge spindle positioned in the second bore and mounted in a second hinge spindle bushing extending through the at least one access port communicating with the second edge and carried on the secondary mounting bracket for receiving the second hinge spindle for pivoting movement therein;
(d) the secondary hinge having a range of pivoting motion of about 90 degrees relative to the spine;
(e) the primary hinge having a range of pivoting motion of about 90 degrees relative to the spine; and
(f) the secondary hinge and the primary hinge having a combined range of pivoting motion of about 180 degrees of the door relative to the door jamb.
2. A 180 degree opening door hinge according to claim 1 , wherein the primary hinge and the secondary hinge are each mounted within first and second thickness planes of the spine.
3. A 180 degree opening door hinge according to claim 1 , wherein the spine includes a plurality of access ports spaced along the length of the spine communicating with the first hinge spindle and second hinge spindle therethrough.
4. A 180 degree opening door hinge according to claim 1 , wherein the spine is no thicker than the door to be attached to the spine by the secondary hinge.
5. A 180 degree opening door hinge according to claim 1 , wherein the first and second edges of the spine are radiused.
6. An enclosure having a door opening, a door jamb surrounding at least one vertical side of the door opening and a door mounted on the door jamb for pivotal 180 degree movement between an open position and a closed position relative to the opening, and comprising:
(a) an elongate spine having first and second longitudinally-extending edges extending along a length thereof and each having a predetermined thickness defining respective first and second thickness planes;
(b) a primary hinge pivotally-mounted adjacent the first longitudinally-extending edge of the spine and having a primary mounting bracket attaching the spine to the door jamb;
(c) a secondary hinge pivotally-mounted in spaced-part relation to the primary hinge and adjacent the second longitudinally-extending edge of the spine for movement independent of the primary hinge, and having a secondary mounting bracket attaching the spine to the door adapted for being opened and closed by pivotal movement of the door in relation to the door jamb;
(d) the secondary hinge having a range of pivoting motion of at least approximately 90 degrees relative to the spine;
(e) the primary hinge having a range of pivoting motion of at least approximately 90 degrees relative to the spine; and
(f) the secondary hinge and the primary hinge having a combined range of pivoting motion of 180 degrees of the door relative to the door jamb;
wherein the enclosure is an aircraft galley unit comprising first and second adjacent door openings each having a door jamb surrounding at least one vertical side of the door opening and a respective door mounted on the door jamb for pivotal 180 degree movement between an open position and a closed position relative to the respective first and second openings, the doors mounted adjacent each other wherein, when either the first or second door is positioned in an open position 180 degrees from the closed position, the door is positioned to the front of the other of the first or second doors and substantially parallel thereto.
7. An enclosure according to claim 6 , wherein the primary hinge and the secondary hinge are each mounted within the respective first and second thickness planes of the spine.
8. An enclosure according to claim 6 , wherein:
(a) the spine includes a first bore and a second bore extending along the respective first and second edges, and having at least one access port communicating with the first edge and the first bore and at least one access port communicating with the second edge and the second bore;
(b) the primary hinge includes a first hinge spindle positioned in the first bore and mounted in a first hinge spindle bushing extending through the access port communicating with the first edge and carried on the primary mounting bracket for receiving the first hinge spindle therein for pivoting movement therein; and
(c) the secondary hinge includes a second hinge spindle positioned in the second bore and mounted in a second hinge spindle bushing extending through the access port communicating with the second edge and carried on the secondary mounting bracket for receiving the second hinge spindle for pivoting movement therein.
9. An enclosure according to claim 8 , wherein the spine includes a plurality of access ports spaced along the length of the spine communicating with the first hinge spindle and second hinge spindle therethrough.
10. An enclosure according to claim 6 , wherein the spine is no thicker than the door to be attached to the spine by the secondary hinge.
11. An enclosure according to claim 6 , wherein the first and second edges of the spine are radiused.
12. An enclosure according to claim 6 , wherein the first and second hinges are positioned to reside during their respective full range of motion within the thickness plane of the spine.
