Abstract
A hinge (20) includes a hinge body (30) pivotally connected with a hinge pin (70) to a leaf (26). The hinge body (30) includes a base (32) supporting a riser portion (36) connected to knuckles (34). The hinge body is configured so that geometry holds a pin retaining member (50). The retaining member (50) includes a portion (56) inserting into a side opening (46) of the knuckles (34) which engages angular groves (74) and (76) formed in the pin (70).
Claims19
A hinge apparatus, comprising:
- a pin, including an annular groove formed therein;
- a hinge body, including a base portion and at least one knuckle, the knuckle defining a tubular opening formed therein configured for receiving the pin, the knuckle including an orifice formed in a side thereof, and a riser portion extending between the base and the knuckle, the riser portion including an alignment member extending outward;
- a pin retaining member having a portion extending into the orifice in the side of the knuckle, the pin retaining member including a portion mounted to the base and aligned by the riser portion.
A hinge apparatus, comprising:
- a pin having an annular groove formed therein;
- a hinge body comprising:
- a base having an orifice formed therein;
- a riser portion extending from the base and having an alignment member;
- a pair of aligned knuckles mounted on the riser portion, wherein each of the knuckles defines a tubular portion configured for receiving the pin, and an orifice formed in the side of each of the tubular portions;
- a pin retaining member having an upper portion configured for inserting into the orifice formed in a side of a first one of the tubular portions, and a lower portion inserting into the orifice in the base, wherein the lower portion includes a hole formed therein configured for receiving the alignment member.
