Abstract
A hinge including a stiffened leaf. The hinge may generally comprise a first longitudinally-extending leaf having a base portion and a mounting portion offset and preferably parallel to the base portion that defines a cavity. The mounting portion may contain at least one hole for attaching the leaf to a hinged object with a fastener. In one embodiment, the hole further includes an annular reinforcement disposed in the cavity proximate to the hole. The hole may be conical in shape and may extend into the reinforcement to receive and support a conically-shaped fastener head. The hinge is suitable for thin leaf construction and continuous full-length hinge applications.
Claims33
A pinned continuous hinge mountable along substantially the entire length of a hinged object, the hinge comprising:
- a first hinge member including at least one first knuckle and a first longitudinally-extending leaf connected thereto, the first leaf including a pair of parallel spaced-apart longitudinally-extending base portions and a longitudinally-extending substantially flat mounting portion disposed therebetween, the mounting portion offset and parallel to the base portions, the mounting portion defining a longitudinally-extending cavity between the base portions, a first plurality of holes defined by the mounting portion and spaced along a first longitudinal axis, a second plurality of holes defined by the mounting portion and spaced along a second longitudinal axis, at least one each of the first and the second plurality of holes having an annular reinforcement disposed proximate to the hole in the cavity and extending outwards from the mounting portion, the mounting portion and reinforcement further defining a conical surface extending through the mounting portion and reinforcement around the periphery of the hole;
- a second hinge member including at least one second knuckle and a second longitudinally extending leaf connected thereto;
- the second leaf including a pair of parallel spaced-apart longitudinally-extending base portions and a longitudinally-extending substantially flat mounting portion disposed therebetween, the mounting portion offset and parallel to the base portions, the mounting portion defining a longitudinally-extending cavity between the base portions, a third plurality of holes defined by the mounting portion and spaced along a third longitudinal axis, a fourth plurality of holes defined by the mounting portion and spaced along a fourth longitudinal axis, at least one each of the third and the fourth plurality of holes having an annular reinforcement disposed proximate to the hole in the cavity and extending outwards from the mounting portion, the mounting portion and reinforcement further defining a conical surface extending through the mounting portion and reinforcement around the periphery of the hole;
- and
- a pin received through the first and second knuckles to pivotably connect the first and second hinge members.

A continuous hinge mountable along substantially the entire length of a hinged object, the hinge comprising:
- a first longitudinally-extending leaf having a length, the first leaf including a substantially flat longitudinally-extending base portion and at least one substantially flat longitudinally-extending mounting portion offset and parallel to the base portion to define a longitudinally-extending cavity between the mounting portion and the base portion, the mounting portion extending along the entire length of the first leaf;
- a longitudinally-extending joining member pivotably connected to the first longitudinally-extending leaf;
- a second longitudinally-extending leaf pivotably connected to the longitudinally-extending joining member;
- and
- a plurality of work-hardened annular reinforcements formed in the cavity and each reinforcement defining a conical mounting hole for receiving a fastener for mounting the first leaf to the hinged object.

A continuous hinge mountable along substantially the entire length of a hinged object, the hinge comprising:
- at least one longitudinally-extending leaf having a length and including a longitudinally-extending base portion having an underside and a thickness, and at least one longitudinally-extending substantially flat raised mounting portion having an underside and a thickness, the underside of the mounting portion offset and parallel to the underside of the base portion to define a longitudinally-extending cavity having a depth;
- at least one hole disposed in the raised mounting portion to attach the leaf to the hinged object, the hole having a conical surface;
- and
- a work-hardened reinforcing ring having a thickness disposed on the underside of the raised mounting portion around the hole, the ring extending into the cavity radially outwards from the hole and perpendicular to the underside of the mounting portion, wherein a combined thickness through the raised mounting portion and ring is greater than the thickness of the raised portion.
