Abstract
A pivot door hinge having a door receiving channel member pivotally connected to a fixed base plate member, the base plate member having a pair of opposing parallel ridge members defining an alignment channel, such that the channel member is retained within the alignment channel until pivoted from the centered orientation, whereby the channel member rests on the ridge members.
Claims20
A pivot door hinge device comprising door self-centering means;
- said door self-centering means comprising a door receiving channel member having a generally rectangular bottom, and a base plate member comprising an alignment channel defined by a pair of generally parallel ridge members, wherein said channel member bottom is pivotable from a centered orientation within said alignment channel and between said ridge members to non-centered orientation wherein said channel member rests upon said ridge members.
A pivot door hinge device comprising:
- a door receiving channel member comprising a generally rectangular bottom;
- a base plate member comprising generally parallel ridge members and a channel bottom surface, said ridge members comprising ridge upper surfaces, ridge interior walls and sloped ends, said ridge interior walls and said channel bottom surface defining in combination an alignment channel adapted to receive said bottom of said channel member;
- pivot means connecting said channel member to said base plate member whereby said channel member may pivot from a centered orientation with said channel member bottom disposed within said alignment channel to a non-centered orientation with said channel member disposed on said ridge upper surfaces.
A pivoting door assembly for pivotally mounting a door between an upper stationary support member and a lower stationary support member, said assembly comprising:
- a door member;
- a base pivot hinge member connected to said door member;
- an upper pivot hinge member connected to said door member;
- said base pivot hinge member comprising a door receiving channel member comprising a generally rectangular bottom pivotally connected to a base plate member having generally parallel ridge members and a channel bottom surface, said ridge members comprising ridge upper surfaces, ridge interior walls and sloped ends, said ridge interior walls and said channel bottom surface defining in combination an alignment channel adapted to receive said bottom of said channel member in a centered orientation;
- whereby said channel member is pivotable from said centered orientation to a non-centered orientation wherein said channel member rests on said ridge upper surfaces.
