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
Claims20
A movement dampened device, comprising:
- a moving component of the device during operation;
- a nonmoving component of the device during operation;
- a device gear connected to one of said moving component and said nonmoving component;
- a damper assembly connected to the other of said moving component and said nonmoving component, said damper assembly including:
- a damper having a rotor and a rotor shaft;
- a damper gear operatively disposed on said rotor shaft for operative engagement with said device gear;
- and
- a biasing means between said damper and said damper gear exerting force against said damper and said damper gear in opposite directions.
A damper assembly comprising:
- a damper including a housing, a rotor in said housing and a rotor shaft extending outwardly from said housing;
- a damper gear disposed on a distal end of said rotor shaft;
- a damper bracket having a body between said damper and said damper gear and legs disposed outwardly of said damper and defining features therein for attaching said damper assembly in a device;
- cooperating engaging structures on said damper housing and said damper bracket for selectively engaging and disengaging said damper housing from said bracket for enabling and disabling relative rotation therebetween;
- and
- said damper bracket defining biasing structure operating against said damper housing and against a side of said damper gear facing said damper housing.
A damper assembly comprising:
- a damper bracket having a body and legs;
- a damper disposed between said damper legs on one side of said damper bracket body;
- a rotor in said damper having a shaft extending outwardly therefrom through said damper bracket body;
- a damper gear disposed on said rotor shaft on a second side of said damper bracket body;
- and
- said damper bracket body configured to provide biasing force from between said damper and said damper gear, said biasing force being exerted against each said damper and said damper gear.
