Publication number: 20020013980Abstract: The door handle assembly includes a door handle which pivots about a pivot axis. A molded-in gear rack is formed on the door handle. The gears of the molded-in gear rack mesh with gears of a rotational damper so that the door handle pivots in concert with the rotation of the gears of the rotational damper. Furthermore, the rotational damper is generally cylindrical and further includes two pairs of radially outwardly extending wings. The rotational damper passes through an aperture in a damper support plate and the first pair of radially outwardly extending wings engage a first side of the damper support plate and engage or abut detent elements. The second pair of radially outwardly extending wings engage a second side of the damper support plate and limit the insertion of the damper through the damper support plate.Type: ApplicationFiled: September 20, 2001Publication date: February 7, 2002Inventors: Joseph J.

Patent number: 6213454Abstract: The damper includes a piston assembly which travels within a cylindrical damper housing between an extended position and a retracted position. A transverse channel is formed proximate to the open end of the damper housing. A latching diamond travels within the transverse channel. The piston assembly includes a piston shaft with a camming wall sub-assembly formed thereon which engages the latching diamond so that the piston assembly is latched in a “push-push” configuration in the extended position. In this latched configuration, the latching diamond is detent engaged by a concave detent apex formed on an island which includes a longitudinally chamfered portion. Additionally, the flexibility of the island in which the concave detent apex is formed may be increased by transverse passageways or “cored-out” areas in the piston shaft immediately adjacent to the island.Type: GrantFiled: March 31, 1999Date of Patent: April 10, 2001Assignee: Illinois Tool Works Inc.Inventors: Steven L.
