Abstract

The invention relates to a door hinge system which includes an integral exposed vertically oriented pin as a portion of a doorframe bracket, and a central latch bracket as engaged to a door. The pivotal manipulation of the door engages the latch of the central latch bracket to the pin, to secure the door to the doorframe. The central latch bracket includes a channel for receipt of the pin which is securely and releasably retained in the channel by the leading cam edge of the latch and safety slide. Disengagement of the latch from the pin enables a door to be easily separated from doorframe for re-hanging at a future time.

Claims

1. A door hanging device comprising:

a door hinge, said door hinge comprising;

a) a door frame bracket engaged to a door frame, said door frame bracket comprising a base having a pin, said pin defining a vertical axis; and

b) a latch bracket engaged to a door, said latch bracket comprising a connecting wall, a central extension comprising a pivot pin, and a channel between said connecting wall and said central extension, said pivot pin having a vertical axis substantially parallel to said vertical axis of said pin, said latch bracket further comprising;

c) a latch, said latch being pivotally engaged to said pivot pin, said latch being constructed and arranged to pivot in a direction orthogonal to said vertical axis, said latch comprising a leading cam edge wherein said leading cam edge is constructed and arranged to engage said pin and releasably secure said pin during the positioning of said pin in said channel, said latch further comprising a slide channel and a slide positioned in said slide channel, said slide being constructed and arranged for slideable positioning over said pin following engagement of said leading cam edge to said pin, and

whereby said latch bracket is rotatable about said in and said door is at least one of attached to and disconnected from said door frame during one of hanging, re-hanging, and uncoupling of said door to said door frame.

2. The door hanging device according to claim 1, said latch bracket further comprising at least one upright support, said pivot pin being engaged to said upright support.

3. The door hanging device according to claim 2, said latch further comprising at least one tong disposed opposite to said leading cam edge.

4. The door hanging device according to claim 3, said door frame bracket further comprising a central shoulder.

5. The door hanging device according to claim 4, wherein said at least one tong is constructed and arranged to contact said central shoulder during engagement of said leading cam edge to said pin whereby said latch is manipulated from a first unlatched position into a second latched position.

6. The door hanging device according to claim 5, said door frame bracket further comprising a side wall, a shaped cutout, a first support, and a second support, said pin extending between said first support and said second support.

7. The door hanging device according to claim 6, said connecting wall comprising at least one hollow area defining at least one tab.

8. The door hanging device according to claim 7, wherein said at least one tab is constructed and arranged for positioning of said pin in said channel.

9. The door hanging device according to claim 8, said slide comprising a slide leading cam edge.

10. A door hanging device comprising:

a door hinge, said door hinge comprising;

a) a door frame bracket engaged to a door frame, said door frame bracket comprising a base having a pin said pin defining a vertical axis; and

b) a latch bracket engaged to a door, said latch bracket comprising a connecting wall, a central extension comprising a pivot pin, and a channel between said connecting wall and said central extension, said pivot pin having a vertical axis substantially parallel to said vertical axis of said pin, said latch bracket further comprising a latch, said latch being pivotally engaged to said pivot pin, said latch being constructed and arranged to pivot in a direction orthogonal to said vertical axis following positioning of said pin in said channel, said latch comprising a leading cam edge, wherein said leading cam edge is constructed and arranged to engage and to releasably secure said pin in said channel following positioning of said pin in said channel, said latch further comprising a slide channel and a slide positioned in said slide channel, said slide being constructed and arranged for slideable positioning over said pin following engagement of said leading cam edge to said pin, and

whereby said door is at least one of attached to and disconnected from said door frame during one of hanging, re-hanging, and uncoupling of said door to said door frame.

11. A door hanging device comprising:

a door hinge, said door hinge comprising;

a) a door frame bracket engaged to a door frame, said door frame bracket comprising a base having a pin, said pin defining a vertical axis; and

b) a latch bracket engaged to a door, said latch bracket comprising a connecting wall, a central extension comprising a pivot pin, and a channel between said connecting wall and said central extension, said pivot pin having a vertical axis substantially parallel to said vertical axis of said pin, said latch bracket further comprising a latch comprising a slide channel and a slide positioned in said slide channel, said latch being pivotally engaged to said pivot pin, said latch being constructed and arranged to pivot in a direction orthogonal to said vertical axis, said latch engaging said pin and releasably securing said pin in said channel following positioning of said pin in said channel whereby said latch is rotatable about said pin, said slide being constructed and arranged for slideable positioning over said pin into a first engaged position following engagement of said latch to said pin, wherein said slide in said first engaged position prevents pivotal unlatching of said latch from said pin, wherein said door is at least one of attached to and disconnected from said door frame during one of hanging, re-hanging, and uncoupling of said door to said door frame.

12. The door hanging device according to claim 11, said latch comprising a leading cam edge comprising a pressure edge, wherein said pressure edge is constructed and arranged to engage said pin and to releasably secure said pin during the latching of said pin in said channel.
