Abstract
This hinge assembly includes normally interengaged leaves, one of these supporting a D-shaped shaft in fixed position. The opposite leaf has bearing sections with open sectors that admit only the minor transverse dimension of the shaft in a praticular relative angular position of the leaves. An abutment on the first leaf prevents disengagement of the second leaf in a position one hundred and eighty degrees from that position.
Claims4
A separable hinge assembly including first and second leaf members and a pin normally interengaging said leaf members to provide a pivotal connection, said hinge assembly having a freedom of articulation of substantially one hundred and eighty degrees, wherein the improvement comprises:
- pin bracket means on said first leaf member receiving said pin in fixed relationship with respect to said first leaf member;
- bearing means on said second leaf member normally embracing said pin around a sector greater than one hundred and eighty degrees, and having a gap adapted to provide a withdrawal passage for said pin in only one predetermined angular relationship of said leaf members;
- and
- abutment means on said first leaf member spaced from said pin to admit said bearing means between said pin and said abutment means said gap being disposed to provide withdrawal with said leaf members in substantially parallel relationship.
