Publication number: 20240151084Abstract: A hinged system includes a preassembled hinge module for pivotally coupling a first component to a second component. The preassembled hinge module includes a shaft, a torque element frictionally engaging the shaft, and a housing. The housing includes a cover, a side wall, and a rear wall that define an interior space enclosed within the housing. The interior space receives the torque element inside the housing. The cover defines a first aperture, and the rear wall defines a second aperture, the first aperture and the second aperture aligned with a pivot axis of the shaft. The shaft extends through at least the first aperture, the interior space, and the second aperture. The shaft is separate from, and configured to be mounted to, the first component. The housing is separate from, and configured to be mounted to, the second component.Type: ApplicationFiled: January 12, 2024Publication date: May 9, 2024Applicant: Southco, Inc.Inventors: Hector Eduardo Rivas, Mark James Rowley, Pradeep Jayanna, Michael Thomas Holland, Richard B.

Patent number: 11187009Abstract: A striker assembly includes a housing, a striker, and a spring. The housing has opposed sidewalls, each of which defines an aperture. The striker extends between the sidewalls of the housing with end portions of the striker positioned within respective apertures defined in the sidewalls. Each of the pair of end portions defines a surface extending in a transverse direction. The spring has a pair of end portions. Each spring end portion contacts the surface of a respective striker end portion. The spring is engaged with the housing to bias the end portions of the striker toward a centered position of the respective apertures. At least one of the end portions of the striker is movable transversely within the respective aperture away from the centered position of the respective aperture and is biased toward the centered position of the respective aperture.Type: GrantFiled: June 28, 2017Date of Patent: November 30, 2021Assignee: Southco, Inc.Inventors: Matthew Butler Frame, Brandon Vaughan Hastings, Richard B.

Patent number: 6174007Abstract: An actuator is used for operating a variety of latching mechanisms. In one embodiment, the latching mechanism includes a rotatable connecting member comprised of a single piece or of separate pieces attached together and the actuator includes a handle assembly operable through pivotal movements of a handle. In operation, the actuator is mountable in a panel or similar member so that the pivoting motion of the handle occurs along a longitudinal axis of the connecting member.Type: GrantFiled: May 19, 1999Date of Patent: January 16, 2001Assignee: Southco, Inc.Inventors: Richard E.

Patent number: 6116660Abstract: A latch has a housing for mounting in a door, panel or the like and a moveable pawl which engages a frame, panel or the like in a fastened position. The latch is provided with a substantially resilient member in the form of a seal, which is adapted to be compressed when the pawl is in the fastened position for inhibiting the passage of matter.Type: GrantFiled: October 3, 1998Date of Patent: September 12, 2000Assignee: Southco, Inc.Inventors: Richard B.

Patent number: 4890869Abstract: A draw latch is provided, of the over-center type, in which the latch has a base, a lever and a catch. The base and lever are pivotally connected to each other, and the catch and lever are pivotally connected to each other. The catch preferably has a lip or hook at its end, for engagement with a member that is to be drawn toward engagement with another member upon which the base is mounted, for drawing those members together, as the lever is moved from an open position to a closed position, through which movements the over-center motion is effected. Dimples or detents are used to provide a resistance to relative motion between the base and the lever on the one hand, and the lever and the catch on the other, through most of the range of their relative movements, but the detents become aligned or nested in one position for assembly of the components under non-frictional conditions, with the detents effecting a spring-like function upon legs of the lever.Type: GrantFiled: September 20, 1988Date of Patent: January 2, 1990Assignee: Southco, Inc.Inventor: Richard B. Langkamp, Jr.
