Patent number: 9297195Abstract: A damper assembly incorporating a bushing adapted to rotate within a wall structure and engage a post on a bin or other element to be controlled. The bushing defines a hub of an integral, coaxial rotor which rides within a fluid containing housing. The bushing and rotor rotate concurrently about a common axis during rotation of the bin or other device being controlled. The drag on the rotor thereby slows the rotation of the engaged post and the associated bin or other structure being controlled.Type: GrantFiled: May 13, 2010Date of Patent: March 29, 2016Assignee: Illinois Tool Works Inc.Inventors: Toby Berry, Jr., David A.
