  • Patent number: 9297195
    Abstract: 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.

  • Patent number: 9261158
    Abstract: A damper assembly includes a housing, a rotor rotatable within the housing, a rotor shaft projecting outwardly of the housing and a damper gear disposed on the rotor shaft. A bracket includes legs disposed outwardly of the damper for securing the assembly in a device, the bracket further having a body between the damper and the damper gear, the body exerting force against each the damper and the damper gear. The damper is selectively engageable with and disengageable from the bracket for enabling and disabling relative movement between the damper and the bracket.

  • Patent number: 8925696
    Abstract: A damper assembly includes a fixed rack gear, a rotary gear damper having a gear engaged with the rack gear and a tether movable with the damper along the rack gear and a tether connecting the damper and a movable object to be controlled by the damper. The tether includes enlarged integral ends to secure the tether relative to the damper and the article to be controlled by the damper. A constant force spring interconnects movement of the damper relative to the fixed rack gear.

  • Patent number: 7753181
    Abstract: A damper for damping movement of an object is formed from silicone impregnated or silicone containing components. The damper includes a housing having walls defining a well and a rotor positioned in the housing within the well. The rotor is positioned to define a space between the rotor and the walls. One or more seals is positioned between the housing and the rotor to isolate the space from the environment. A damping fluid is present in the well between the rotor and the housing for damping rotation of the rotor relative to the housing. The housing, the rotor and the seals are formed from silicone containing or silicone impregnated materials. The damping fluid is also a silicone based material.
