Abstract
A hinge assembly for garage doors with relatively loose tolerance for the leaf assemblies and the central supporting member. A sleeve is rotably mounted over the supporting member and a folded portion of the leaf assembly journals the sleeve for a substantially frictionless linkage. The sleeve is made of a self-lubricating plastic material to reduce noise.
Claims3
A hinge assembly comprising:
- A) a first leaf assembly having a first flat portion with first and second ends, and including first and second angular walls perpendicularly mounted to said first and second ends, respectively;
- B) a supporting member rigidly mounted between said first and second angular walls to prevent any rotational or translational movement of said supporting member relative to said angular walls;
- C) a sleeve member rotably mounted over said supporting member;
- and
- D) a second leaf assembly having a second flat portion and a folded portion journaling said sleeve so that said second leaf assembly rotates about said sleeve and supporting member.
