Abstract
A door assembly is provided with a handle that is movable between a first handle position where the door assembly is unlatched and a second handle position where the door assembly is latched. The handle may also be movable to a third handle position where the door assembly is locked. A hollow conduit is operatively connected to the handle at a first end. A wire is disposed within the conduit and operatively connected to the handle such that the wire translates within the conduit when the handle is moved. A damping material is positioned between an outer surface of the wire and an inner surface of the conduit. The damping material is configured to dampen the motion of the handle. In one example, the damping material is silicone grease.
Claims16
A door assembly comprising:
- a handle movable between at least two positions:
- a first handle position where the door assembly is unlatched and a second handle position where the door assembly is latched;
- a hollow conduit operatively connected to the handle;
- a wire disposed within the conduit and operatively connected to the handle, wherein the wire translates within the conduit when the handle is moved;
- and
- a damping material positioned between an outer surface of the wire and an inner surface of the conduit, the damping material being configured to dampen the motion of the handle.
A door assembly comprising:
- a handle movable between three positions:
- a first handle position where the door assembly is unlatched, a second handle position where the door assembly is latched and unlocked, and a third handle position where the door assembly is locked;
- a hollow conduit operatively connected to the handle;
- a wire disposed within the conduit and operatively connected to the handle, wherein the wire translates within the conduit when the handle is moved;
- and
- a damping material positioned between an outer surface of the wire and an inner surface of the conduit, the damping material being configured to dampen the motion of the handle;
- and
- wherein the damping material has a viscosity that is between approximately 225,000 cP and 325,000 cP at 25° C.
A vehicle comprising:
- an entryway;
- a door assembly for the entryway, the door assembly having:
- an interior-facing member;
- a handle operatively connected to the interior-facing member and movable between at least two positions;
- a hollow conduit operatively connected to the handle;
- a wire disposed within the conduit and operatively connected to the handle, wherein the wire translates within the conduit when the handle is moved;
- a latch mechanism operatively connected to the wire such that the translation of the wire within the conduit actuates at least one component of the latch mechanism in order to selectively unlatch, latch and lock the door assembly;
- a damping material positioned between an outer surface of the wire and an inner surface of the conduit, the damping material being configured to dampen the motion of the handle;
- and
- wherein the damping material is silicone grease.
