Publication number: 20080040887Abstract: A hinge assembly mounts a video display screen to a surface, and more particularly to the passenger compartment of a vehicle. The hinge assembly allows for the pivotal attachment of a video display screen to a surface, preferably the ceiling of a vehicle, using a friction hinge. The hinge assembly may include a resilient washer that is attached to the hinge assembly on a pin. The resilient washer functions to limit axial movement of the hinge assembly along the pin and is adapted to prevent the hinge assembly from locking-up during rotational movement of the video display screen.Type: ApplicationFiled: August 16, 2006Publication date: February 21, 2008Inventor: Harry L. Dickerson

Patent number: 6761521Abstract: A captive screw including a screw and a ferrule is disclosed. One end of the ferrule is adapted for engagement to a hole in a panel to be secured by the captive screw. The screw has an annular flange that is captured within the bore of the ferrule. The screw has a shaft with a threaded portion. The threaded portion of the screw shaft can be made to extend from the ferrule to varying amounts as the screw is moved relative to the ferrule between extended and retracted positions. An optional spring may be provided in the ferrule to bias the screw toward the retracted position.Type: GrantFiled: December 14, 2001Date of Patent: July 13, 2004Assignee: Southco, Inc.Inventors: Edward A. McCormack, Thomas J. Ellis, Danin Sewalt, Harry L. Dickerson, Michael Menta, Kyle Sareyka, Richard Lewis, Thomas Aukzemas, James Wanstall

Patent number: 6238155Abstract: A torque screw having a screw with a head and a threaded shaft, a knob having a central longitudinal axis coaxial with the screw and a one-directional ratchet disposed between the knob and the screw that engages to allow the screw to be disengaged in a counter-clockwise direction using the knob, and engages when rotated in a clockwise direction to a predetermined torque value. Once that predetermined torque value is reached, the ratchet is caused to slip such that the knob turns relatively freely with respect to the screw.Type: GrantFiled: June 18, 1998Date of Patent: May 29, 2001Assignee: Southco, Inc.Inventors: Thomas V. Aukzemas, Thomas J. Ellis, Harry L. Dickerson, Lianli Ji

Patent number: 6086480Abstract: A method of making a knob and ferrule for a captive screw is disclosed, the knob integrally attached to the screw, the ferrule attachable to a panel. The method of making the knob includes providing an aluminum alloy base metal for the knob, pressing by cold-forming the base material into a generally cylindrical cup-shaped article using at least one pressing operation, the cup having a generally cylindrical side wall, removing any base material situated outside the perimeter of the cup-shaped cylindrical article, and providing a hole in the bottom of the cup, coaxial with the hollow cylindrical walls of the cup, thereby forming the knob.Type: GrantFiled: April 28, 1999Date of Patent: July 11, 2000Assignee: Southco, Inc.Inventors: Thomas J. Ellis, Edward A. McCormack, Harry L. Dickerson

Patent number: 5865582Abstract: A one-directional captive screw attachable to a panel that is hand tightenable, but requires a tool to loosen once hand tightened. The captive screw includes a screw having a head with a recess and a threaded portion, a knob having a central longitudinal axis coaxial with the screw, a one-directional ratchet between the knob and the screw. The ratchet engages to allow the screw to be tightened in a clockwise direction using the knob, and disengages when rotated in a counterclockwise direction, such that a tool is required to loosen the screw by use of the recess.Type: GrantFiled: March 5, 1997Date of Patent: February 2, 1999Assignee: Southco, Inc.Inventors: Thomas J. Ellis, Harry L. Dickerson
