Patent number: 8414058Abstract: A vehicle hinge set for supporting and operating decklid closures on a vehicle include at least one primary unit, at least one secondary drive unit slidably receivable against a primary unit, and a mount for supporting the aligned primary and secondary units. The primary unit combines a decklid strap pivotably connected to the primary unit, and may include a biasing mechanism. The secondary unit is mechanically and electrically coupled for motorized displacement of the strap of the primary unit.Type: GrantFiled: April 1, 2010Date of Patent: April 9, 2013Assignee: M&C CorporationInventor: Michael John Duffy

Patent number: 6648398Abstract: A method and apparatus for coupling a vehicle body panel partition for pivotal movement between an upright and a retracted position. A mounting includes hinge sets formed from two hinge leafs, each hinge leaf being used to retain one of the alternate ends of the torsion rod pin extending through aligned pivot portions on each pin leaf. Preferably, each hinge set is integrally formed with the torsion pin by retainers holding ends of the torsion pin with respect to each of the leafs. In the preferred embodiment, a return bent end of the torsion pin is received in an extended support member while the other end is retained in a returned bent portion of the second leaf, each end extending in a radial direction aligned at an angle to the direction of the other end.Type: GrantFiled: January 9, 2001Date of Patent: November 18, 2003Assignee: M&C CorporationInventor: Michael John Duffy

A mounting includes hinge sets formed from two hinge leafs, a hinge leaf being used to retain one of the ends of the torsion rod pin extending through aligned pivot portions on each hinge set. Preferably, each hinge set is integrally formed with the torsion pin by retainers holding ends of the torsion pin with respect to one leaf of each of the hinge sets. In the preferred embodiment, a return bent end of a common torsion pin is received in a first leaf of one of at least two hinge sets, while the other end of the rod is bent and retained in a second leaf of a second hinge set.Type: GrantFiled: September 27, 2002Date of Patent: September 16, 2003Assignee: M & C CorporationInventor: Michael John Duffy

Patent number: 6447043Abstract: A vehicle body closure assembly combines a hinge, that provides a plurality of pivot axes that are aligned with a common intersection point above a body opening closed by a closure panel hinged to the vehicle body, and a displacement limiter that controls the open position of the closure so that the hinge pieces maintain a stable alignment with respect to each other. Preferably, the hinge structure or adjacent supports include the displacement limiter. A panel mount defmes a first hinge axis, a body mount defines a second axis and a pair of links are pivotally secured together between the panel mount and the body mount to complete a hinge set. Preferably, a pair of hinge sets are secured to the hinge side of the closure panel to align said panel for movement in a non-interfering path with respect to body portions adjacent the path.Type: GrantFiled: January 9, 2001Date of Patent: September 10, 2002Assignee: M & C CorporationInventors: Marinus T. VandenHeuvel, Rafael Perlin, Michael John Duffy
